Description

Punching mold mechanism capable of multi-directional punching processing {PUNCHING MOLD DEVICE CAPABLE OF HORIZONTAL PUNCHING}

The present invention relates to a punching mold mechanism capable of performing multi-direction punch processing by being coupled to a conventional press device that moves vertically and horizontally, and can perform punching processing in multiple directions on a workpiece by being coupled to an existing movable press. And, it can be easily coupled to the press so that it can be punched in a desired angle and direction, and a number of punching mold mechanisms can be provided in one movable press, improving work efficiency by performing a number of punching processes with one press operation. The present invention relates to a punching mold mechanism capable of improving the strength of the workpiece, preventing damage to the workpiece or generating defective products, and improving the strength of the workpiece because it is a forged mold type.

In general, a bar-shaped raw material is processed to manufacture a bit that is coupled to a driver or a coupling member with a groove on the side. To this end, the outer peripheral surface of the processed product is cut and ground, and processing for groove formation. You get a processed product by doing the same.

In particular, in the case of manufacturing a cross-shaped driver bit, it is manufactured as described in Korean Patent Publication No. 10-1507492 "Cross-shaped driver bit and method of manufacturing a cross-shaped driver bit (hereinafter, Prior Document 1)", Looking at this, as shown in FIG. 14, the workpiece, which is the main body of the driver bit, is first cut into a conical shape, and then compressed on the side and the upper surface, respectively, and then pressed to produce a driver bit.

However, there is a problem that the manufacturing cost is increased and the manufacturing process is complicated due to many process steps to manufacture the driver bit, and the upper mold 210 is manufactured by pressing the upper mold 210 having a cross-shaped cavity from both sides. If the original pressurization direction is deviated due to this external impact or the like, there is a concern that defective products will be manufactured.

Accordingly, it is possible to mass-produce by simplifying the manufacturing process, and it is necessary to develop a technology capable of preventing the position of the pressing mold from changing to prevent the production of defective products when side pressing for manufacturing is performed.

On the other hand, in the case of the conventional press device, a vertical press that moves the mold in the vertical direction is widely used, whereas in the case of a technology that requires a side pressing process such as manufacturing a driver bit, there is a problem that it is impossible to manufacture using the existing vertical press. .

In addition, in order to solve this problem, even if the processed product is laid in a horizontal direction and the press work is performed, it is easy to be processed in a shape that is tilted downward, and there is a concern that the precision of the work is also degraded.

On the other hand, for the technique of pressing in the lateral direction, "Horizontal punching device (hereinafter, Prior Document 2)" is described in Korean Utility Model Publication No. 20-0140227 (see Fig. 15).

This prior document 2 is an actuator including a drive cam 10 that transmits power vertically downward, and a sliding cam 11 that is horizontally connected to the drive cam 10 to transmit power horizontally, and the actuator of the actuator A punch 12 horizontally connected to the sliding cam 11 to perforate by applying a blow to the material, a block 20 supporting the back side of the material so that the material is not pushed back by the punch 12; And it is installed in the groove of the block 20 so that the center of the punch 12 is aligned to support the back side of the punch 12 of the material, and one side is opened so that the punch 12 penetrating the material enters. In the horizontal punching apparatus including the die 21, the sliding cam 11 and the block 20 are placed on and fixed to the flat cam holder 30, and the liner 31 is placed on the entire bottom of the cam holder 30. It is characterized in that it is configured to move the drilling position in a state in which the centers of the punch 12 and the die 21 are aligned by inserting or chamfering.

However, in Prior Document 2, it is only described that the actuator connecting the drive cam 10 and the sliding cam 11 is moved to perform punching processing, and the point in which the drive cam is connected to the existing vertical press is described. It is difficult to apply to the existing vertical press because it is not, and even if the punch 12 moves horizontally, there is no description of a configuration that will prevent the position change even when used for a long period of time.

Therefore, it is necessary to develop a technology that can solve these problems, and furthermore, punching processing not only in horizontal direction but also in multi-direction is possible, and it can be applied to horizontal press as well as vertical press, so that punching can be processed at a desired angle. There is a need to develop a mold mechanism.

Another embodiment of the guide unit is shown, and Fig. 12 is a view showing another embodiment of the guide unit according to the present invention applied, and Fig. 13 is a cross-sectional view and a perspective view showing various embodiments of a workpiece processed through a punching mold mechanism according to the present invention. It is represented by

In the punching mold mechanism capable of multi-directional punching according to the present invention, the movable press moves up and down to directly couple to the movable press for press work to perform punching in multi-direction on the workpiece, and the upper fixing part 100, processing It consists of a unit 200, a switching unit 300 and a lower fixing unit 400.

The upper fixing part 100 is directly coupled to the working surface of the movable press 2, that is, the lower surface of the movable press 2 on which the press operation is performed, and is composed of an upper fixing part body 110 and a contact member 120. .

The upper fixing body 110 has a'Π' shape in cross section in the punching processing direction, and the upper surface 110a is fixedly coupled by direct contact with the mold, and a pair of shaft couplers at the bottom of the upper surface 110a ( 111) is formed protruding downward.

The shaft coupler 111 is formed in a pair and is spaced apart from each other to protrude, and the vertical moving shaft 310 of the switching unit 300 is interpolated and coupled to the spaced distance between the shaft coupler 111.

In addition, a shaft coupling hole 111a formed through the shaft coupling hole 111 in a direction perpendicular to the protruding direction of the shaft coupling hole 111, that is, in a horizontal direction vertical to the vertical direction, is formed.

When the vertical moving shaft 310 described later is interpolated and coupled, the shaft coupling hole 111a penetrates the upper through-shaft 130 through the shaft coupling hole 111a, and the shaft coupling hole 111, vertical moving shaft (310), the shaft coupling unit 111 is combined in an overlapping state in that order.

Therefore, the upper fixing part 100 and the vertical moving shaft 310 are coupled through the shaft coupling part 111, and a part of the upper end of the vertical moving shaft 310 is interpolated into a space spaced apart between the shaft coupling parts 111 Because it is combined in a state, the bonding strength can be improved.

In addition, a close contact member 120 protruding downward is provided in the center of the upper surface of the upper fixing part 100, that is, a space between the shaft coupling holes 111.

The contact member 120 is formed to protrude along the lower horizontal direction of the upper surface 110a in the same manner as the shaft coupling member 111, and the lower surface of the contact member 120 has a curved surface corresponding to the upper surface of the upper through-shaft 130 ( 120a) is formed by being recessed upward, and the upper through-shaft 130 is inserted into the curved surface 120a to be coupled.

This is because the upper fixing part 100 moves up and down by the upper surface, but by the lower fixing part 400, which will be described later, it is inclined toward the lower fixing part 400 rather than a completely vertical movement, so that the processing part 200 can be horizontally moved. Because it is adjusted so that the vertical movement shaft 310 is rotated about a certain range around the upper through-axis (130). At this time, the shaft coupling unit 111 coupled with the upper through-shaft 130 is also rotated, but it is shaken during rotation due to the space between the vertical moving shaft 310 and the lower end of the upper surface 110a of the upper fixing part 100 In order to prevent unstable rotation, the curved surface of the contact member 120 abuts the upper surface of the upper through-shaft 130 so that the upper fixing part 100 can be easily rotated along the upper through-shaft 130. .

The processing unit 200 is connected to the conversion unit 300 to perform punching processing in the horizontal direction through the conversion unit 300, in which one side collides with the workpiece to perform punching processing, and the other side is the conversion unit It is connected to and moves in the horizontal direction according to the vertical motion of the movable press (2).

The processing unit 200 is formed with a processing body 210, a punch 220, and a coupling bracket 230.

First, the processing body 210 has a prismatic shape, a punch 220 is provided at one end, and a coupling bracket 230 is provided at the other end to be coupled with the first connector 310 of the switching unit 300.

The punch 220 directly collides with the workpiece P to perform a punching process, and the user makes a punch 220 corresponding to the desired depressed shape to obtain a finished product having a desired shape. It is combined in a form. At this time, the punch 220 is inserted along the center of the processing body 210, the end of the punch 220 having a processing shape toward the processing surface side of the processing body 210 is exposed to the outside, and the other end is a coupling bracket 230 When the punch 220 is replaced by being exposed on the same surface as ), the punch 220 protruding toward the processing surface is pressed in the other direction to separate the punch 220 from the processing body 210.

The punch 220 performs punching processing while being in contact with or away from the workpiece P in the horizontal direction according to the movement of the processing unit 200.

Accordingly, a punch 220 is provided at one end of the processing body 210 and a coupling bracket 230 is provided at the other end.

The coupling bracket 230 is provided at the other end of the processing body 210, and is connected to the first connector 320 by extending a predetermined length in height and width from the processing body 210.

At this time, the lower surface of the coupling bracket 230 directly contacts the die 3, and the other end of the processing body 210 is provided at the center of the connection surface with the coupling bracket 230. Accordingly, the processing body 210 performs a horizontal motion with the die 3 and the height spaced apart from the die 3 centering on the portion in contact with the coupling bracket 230.

The coupling bracket 230 has a through hole 231a through which the first through shaft 320a can be penetrated, and the center has a first through-hole 231a formed on both side surfaces 231 around the surface coupled with the processing body 210. It is recessed in the direction in which the punch 220 is located by the diameter of the through shaft 320a. At this time, after the first through-shaft 320a is passed through the recessed inner surface, the coupling bracket 230 corresponds to the outer circumferential surface of the first through-shaft 320a so that it can be rotated around the first through-shaft 320a. A recessed recessed surface 232 is formed.

Therefore, when the coupling bracket 230 is inserted into the first connector 320 to be described later and then penetrated through the first through shaft 320a, the coupling bracket 230 can be rotated around the first through shaft 320a. To be.

On the other hand, through the lower fixing part 400, the conversion unit 300 is moved within a certain range, so that the processing unit 200 is moved in the horizontal direction, and the force transmitted from the conversion unit 300 to the processing unit 200 Accordingly, there is a fear that the processing unit 200 may move along the upper surface of the die 3.

This is because the impact generated when the processing unit 200 is punched, or the portion where the processing unit 200 and the conversion unit 300 are combined decreases due to long-term use, so that the configuration of the processing unit 200 is centered on the punching direction. Since there is a possibility that the product may be shaken from side to side, in this case, a large problem occurs that a defective product is produced by affecting the processing direction of punching processing.

In addition, since the processing body 210 is provided spaced apart from the upper surface of the die 3, it is unstable, and there is a concern that defective products may be manufactured even when inclined in the vertical direction.

Therefore, in the present invention, the processing unit 200 is to be moved only in the horizontal direction, that is, in the punching direction, and a guide unit 500 that can be prevented from leaving the installation position by shaking from side to side due to external force or the like is additionally configured (Fig. 8).

The guide part 500 has a larger rectangular shape than the processing part 200, and a guide hole 510 through which the processing part 200 passes is formed in the center, so that the processing part 200 is inserted into the guide hole 510 and It penetrates and moves horizontally.

At this time, the guide hole 510 has a shape corresponding to the cross-section of the processing body 210 and is formed to penetrate in the same direction as the moving direction of the processing unit 200.

In addition, lower fasteners 520 protruding in the vertical direction are formed on both lower side surfaces of the guide part 500, that is, a surface perpendicular to the guide hole 510. The lower fixing member 520 has a plurality of holes (not shown in the drawing) penetrating in the vertical direction, and a separate coupling member is interpolated and coupled with these holes so that the guide part 500 is fixed to the upper surface of the die 3 . At this time, a bolt through hole (not shown in the drawing) is arbitrarily arranged in the lower fastener 520 in the vertical direction so that the guide part 500 can be firmly fixed to the upper surface of the die 3 through a coupling member such as a bolt. do.

Therefore, by moving the processing unit 200 along the guide hole 510 of the guide unit 500, the switching unit 300 is moved out of the position where the processing unit 200 is installed or when the movable press 2 is raised. It also prevents being lifted along, guides the movement of the processing unit 200, and can play a role of fixing to the die 3. In addition, since the processing unit 200 is moved only in the same direction for a long period of time through the guide unit 500, the accuracy of punching processing can be maintained.

On the other hand, since the above-described guide part 500 is provided near the position where the punch 220 punches the workpiece P, there is no problem when punching in one direction, but when punching is performed in multiple directions, a plurality of guides There is a problem that the parts 500 may collide with each other, and there is a problem that there is insufficient space to be installed along the periphery of the workpiece P.

Therefore, the upper and lower surfaces of the guide part 500 disposed around the workpiece P are centered on the center of the corresponding surface facing the workpiece P, and the distance between the two sides is far from the punch 220. It has an inclined surface 521 that gradually widens as it gets smaller. This inclined surface 521 has an inclination from the front center to both side surfaces as shown in FIG. 8, so that even if the guide part 500 is installed along the periphery of the workpiece P, the inclined surface 521 does not collide between the guide parts 500, Make sure it can be installed sufficiently At this time, the inclined surface 521 is made to have an inclination as a whole from the lower fastener 520 to the guide part 500.

Therefore, by forming the inclined surface 521 having an inclination on the corresponding surface, even if the punching mold mechanism 1 including a plurality of guide parts 500 is installed, as shown in FIG. 10, the workpiece P can be easily Make sure it can be installed along the perimeter.

In addition, a fixing protrusion 530 protruding downward may be additionally provided on the lower surface of the guide part 500 so as to firmly fix the die 3 and the guide part 500.

This fixing method of the fixing protrusion 530 performs a perforation in a corresponding shape so that the fixing protrusion 530 can be fitted at a position where the guide part 500 is to be installed on the upper surface of the existing die 3, In this way, the fixing protrusion 530 is inserted into the recessed groove so that the guide part 500 can be fixed and positioned at the correct position on the upper surface of the die 3. Therefore, the guide part 500 is more rigidly coupled and installed to the die 3 through the fixing protrusion 530, so that the position of the machining part 200 does not change even during frequent punching of the machining part 200. The processing part 200 is fixed and the guide part 500 is also securely fixed to the die 3 together.

The conversion unit 300 uses the vertical motion of the movable press 2 to switch the movable direction so that the processing unit 200 can perform horizontal movement, and the upper fixing unit 100 and the processing unit 200 are in a certain range. It plays the role of fixing and combining so that it can be moved within.

The conversion unit 300 has one end connected to the upper fixing part 100, the other end connected to the processing part 200, and the upper fixing part 100 and the processing part 200 are coupled in a form orthogonal to each other. The conversion unit 300 is a vertical moving shaft 310 directly connected to the upper fixing part 100, a first connector 320 directly connected to the processing part 200, and connected to the lower fixing part 400. The second connector 330, the vertical movement shaft 310, and the first and second connectors 320 and 330 are composed of a central bracket 340 connected to one.

First, the vertical movable shaft 310 is inserted into the lower surface of the upper fixing part 100, that is, in a space spaced apart between the shaft coupler 111 and is penetrated by the upper through-shaft 130, and the movable press ( According to the vertical motion of 2), the first and second connectors 320 and 330 and the central bracket 340 are moved up and down together.

When the vertical moving shaft 310 is combined with the upper fixing part 100, the upper connector 311 formed on the upper side is interpolated into the spaced apart space between the shaft coupler 111 to be in the center of the upper connector 311 The formed upper connection hole 311a and the shaft coupling hole 111a are in communication with each other, and the shaft coupling hole 111 and the upper connector 311 are inserted and fitted in the vertical direction.

At this time, the diameters of the upper connection hole 311a and the shaft coupling hole 111a are the same, and these diameters are coupled to correspond to the diameter of the upper through-shaft 130. In addition, the separation distance between the shaft coupling unit 111 is manufactured to be the same as the width of the upper end of the vertical moving shaft 310 so that the upper end of the vertical moving shaft 310 of the separation distance between the shaft coupling unit 111 is inserted into the upper connection hole ( 311a) and the shaft coupling hole 111a to be in communication.

When the upper connector 311 is inserted into the shaft coupling hole 111 and comes into close contact, the upper through shaft 130 passes through the communicating shaft coupling hole 111a and the upper connection hole 311a to be coupled (Fig. 7a). Reference).

It has a prismatic shape of the vertical movement shaft 310, and the lower end is coupled to the center of the upper surface of the central bracket 340. At this time, the vertical movement shaft 310 and the central bracket 340 are integrally manufactured so that the central bracket 340 can easily move according to the vertical movement of the vertical movement shaft 310.

The first connector 320 has one end coupled to the coupling bracket 230 formed at the other end of the processing unit 200, and the other end coupled to the second connector 330 and the central bracket 340, and through holes formed on both sides 321 and a first through shaft 320a coupled to the through hole 321, respectively, and a central member 322 in close contact with an outer peripheral surface of the central through-hole 340a.

The through hole 321 is formed on both sides of the first connector 320, and holes 321a are formed at one end and the other end. The diameter of the hole 321a formed at one end of the hole 321a, that is, at the position where the processing part 200 is coupled, corresponds to the diameter of the first through shaft 320a, and the first through shaft 320a is It is inserted through the die 3 in a direction parallel to it.

In addition, the diameter of the hole 321a formed at the other end of the through hole 321, that is, at a position coupled with the second connector 330 and the central bracket 340, corresponds to the diameter of the central through shaft 340a, and The through shaft 340a is inserted through the die 3 in a direction parallel to the die 3.

The central member 322 is located in the center of the first connector 320 and is provided in a state spaced apart from the through holes 321 on both sides. At this time, the central member 322 and the through hole 321 are connected by extending the center of the through hole 321 toward the through hole 321. That is, the through hole 321 and the central member 322 are manufactured in an integral type with the side centers connected to each other.

At this time, both side surfaces of the side of the central member 322 on the side where the through hole 321 is not located do not collide with the first through shaft 320a or the central through-shaft 340a that are inserted into the hole 321a, respectively. , In a form that can be in close contact with the outer circumferential surface, a curved surface 322a that is recessed to correspond to the outer circumferential surface is formed, respectively.

In addition, the spaced space between the central member 322 and the through hole 321 is spaced apart by the width of each of the components to be combined.

That is, one end connected to the first connector 320 and the processing unit 200 as shown in FIG. 7B is combined with the central member 322 and the through hole 321 spaced apart by the width of the protruding side of the coupling bracket 230. The side of the bracket 230 is interpolated in the horizontal direction into the spaced space between the through hole 321 and the central member 322. Thereafter, when the through hole (231a) of the coupling bracket (230) and the hole (321a) formed in the through hole (321) are inserted to communicate with each other, the first through shaft (320a) is intubated into the inside of the holes (231a, 321a) communicated. do.

At this time, the first through-shaft 320a penetrates through the through hole 321 and the coupling bracket 230 and is in close contact with the inner side of the curved surface 322a of the central member 322, and again, the coupling bracket 230 and the through hole 321 ) Are inserted in the order of passing through.

Accordingly, the processing unit 200 and the first connector 320 rotate around the first through shaft 320a.

Likewise, the other end of the through hole 321 has a hole 321a at the other end and an inner connector 331 that is one end of the second connector 330 in the horizontal direction in the spaced apart space between the through hole 321 and the central member 322 When the hole 321a of the other end of the through hole 321 and the hole 331a of the inner connector 331 are interpolated to communicate with each other, the central through-shaft 340a is internally intubated and coupled. In addition, the inner intubated central through-shaft 340a has a curved surface 322a formed on the other end of the central member 322 in close contact with the outer circumferential surface, so that the first connector 320 can be rotated around the central through-shaft 340a. Yes (see Fig. 7c).

Meanwhile, the upper through-shaft 130, the first and second through-shafts 320a and 330a, and both ends of the central through-shaft 340a are recessed in the inner center so that snap rings (not shown in the drawings) can be provided. The snap ring keyway (131, 320b, 330b, 340b) is formed, respectively.

Inside the snap ring keyway (131, 320b, 330b, 340b), a ring having high frictional force such as a snap ring is coupled to the recessed inner side of the snap ring keyway (131, 320b, 330b, 340b), and the upper penetration shaft 130, The first and second through-shafts 320a and 330a and the central through-shaft 340a are prevented from being separated from each of the through-coupled configurations, and maintain the coupled state.

The second connector 330 is composed of an inner connector 331 formed in a direction connected to the first connector 320 and an outer connector 332 formed in a direction connected to the lower fixing part 400.

First, the inner connector 331 is formed by protruding both sides of the second connector 330 in the connection direction, and each inner connector 331 is spaced apart by the width of the central member 322 of the first connector 320 Lose.

In addition, the inner connector 331 is formed with a hole 331a passing through the die 3 in a horizontal direction, and as described above, the first and second connectors are interpolated in the horizontal direction to the other end of the first connector 320. The holes 321a and 331a formed in the connector 320 and 330, respectively, communicate with each other.

When the first connector 320 and the second connector 330 are interpolated and overlapped, the center bracket 340 descends upward to the outer surface of the through hole 321 of the first connector 320 and is in close contact. Therefore, the outer surface of the inner connector 331 is in close contact with the inner surface of the first connector 320 and the through hole 321, and the outer surface of the through hole 321 of the first connector 320 is the central bracket 340 It overlaps in close contact with the lower inner side. Thereafter, the central through-shaft 340a penetrates through the first and second connectors 320 and 330 and the lower end of the central bracket 340 and is coupled.

In addition, the inner connector 331 does not collide with the outer circumferential surface of the central through shaft (340a) when coupled with the central through-shaft (340a), and the first and second connectors (320, 330) are easily along the central through-shaft (340a). It is depressed inward to correspond to the outer peripheral surface of the central through-shaft (340a) so that it can rotate.

In addition, when the second through-shaft 330a is penetratingly coupled to the outer connector 332 described later on the other surface opposite to the direction in which the inner connector 331 protrudes, horizontally to correspond to the outer peripheral surface of the second through-shaft 330a. A protruding protruding surface 331b is formed. The protruding surface 331b also has a curved surface recessed to correspond to the outer circumferential surface of the second through-shaft 330a on the surface abutting the outer circumferential surface of the second through-shaft 330a, and is formed to protrude apart from the outer connector 332. , The side connector 411 of the lower fixing part 400 is interpolated and positioned at a distance between the protruding surface 331b and the outer connector 332.

The outer connector 332 is formed on both side surfaces centering on the opposite side in the horizontal direction of the inner connector 331, and the side connector 411 of the lower fixing part 400 on the inner side of the spaced space between the outer connector 332 Is inserted inward. At this time, when the side connector 411 is inserted in the horizontal direction, it is inserted into a space separated from the outer connector 332 and the protruding surface 331b, through which the hole 332a and the side connector 411 of the outer connector 332 ) Of the hole 411 is communicated. Thereafter, the second through-shaft 330a is inserted into the inside of the communicating holes 332a and 411. Through this, the outer connector 332 and the side connector 411 are connected.

The central bracket 340 has a prismatic shape in which the side and bottom surfaces of the first and second connectors 320 and 330 are open, and a central part of the upper surface is opened. At this time, a portion of the upper surface is opened in a form that connects the open sides, and is coupled to the lower surface of the vertical movement shaft 310 at the center of the upper surface of the central bracket 340, and within the center of the upper surface of the central bracket 340. A lower contact hole 342 is protruded on the side so as to be in close contact with the upper outer peripheral surface of the central through-shaft 340a.

At this time, since the lower surface of the central bracket 340 is opened, when the central bracket 340 is raised by the movable press 2, the first connector 320 rotates downward around the central through-shaft 340a. For this reason, the processing unit 200 can be moved horizontally.

The lower side of the side of the central bracket 340 protrudes downward, that is, in the direction in which the die 3 is provided, and is provided on the upper surface of the die 3. The bracket through hole 341 is formed in the central bracket 340 so that the central through-shaft 340a can pass therethrough.

Therefore, when the central bracket 340 is coupled with the first and second connectors 320 and 330, the holes 321a and 331a of the first and second connectors 320 and 330 and the bracket through hole 341 communicate with each other, The central through-shaft (340a) is connected to the inner intubation through the communication.

The lower fixing part 400 is fixed to the upper surface of the die 3 or the side of the movable press, and serves to fix the movement of the punching mold mechanism 1 only within a certain range.

In other words, it serves to prevent the processing unit 200 from vertically moving according to the movement of the movable press 2 through the lower fixing unit 400, and to fix the processing unit 200 so as to move along the punching direction. .

The lower fixing part 400 is composed of a connection member 410 connected to the second connector 330 and a fixing member 420 fixing the connection member 410.

First, the connecting member 410 has a pair of side connectors 411 protruding in the horizontal direction on both sides of one side, and the outer peripheral surface of the second through shaft 330a on the inner surface of the space spaced between the side connectors 411 The curved surface 412 is recessed to correspond to.

This side connector 411 is formed with a hole 411a penetrating in the lateral direction in the center, which is inserted into the inner side of the outer connector 332 of the second connector 330 as described above to the outer connector 332 It communicates with the hole 332a and is coupled through the second through shaft 330a.

The connecting member 410 has a part including a surface opposite to the surface on which the side connector 411 is formed is interpolated into the fixing member 420, and the fixing member 420 includes an upper surface and a rear surface, that is, a connecting member ( The fixing member body 421a having an open surface opposite to the direction in which 410 is located, and having a shape corresponding to the open upper surface of the fixing member body 421a, is provided on the upper surface of the fixing member body 421a to open A top surface finishing member 422 closing the upper surface of the structure, and a rear surface having a shape corresponding to the open rear surface of the fixing member body 421a, and provided on the rear surface of the fixing member body 421a to close the open rear surface It consists of a closing member 423 (see Figure 6a).

The fixing member body 421a is formed with fixing protrusions 421a that can be fixed to the die 3 on both sides around the direction in which the connection member 410 is inserted, so that the fixing protrusions 421a and the die 3 ) It is possible to fix the fixing member body (421a) to the die (3) through a separate coupling member such as a bolt that can be fixed through the vertical direction.

The fixing member body 421a has a surface in which the connecting member 410 is inserted and a surface opposite to the surface in which the connecting member 410 is inserted, that is, a surface located in the direction in which the processing unit 200 is moved, and the surface in which the connecting member 410 is inserted first When the first and second connectors 320 and 330 are positioned in a straight line, they are inserted into the insertion hole 421b formed to have a height if they match the height spaced apart from the upper surface of the die 3. At this time, the lower surface of the fixing member body 421 is not provided with the same length as the fixing protrusion (421a), and the connecting member 410 is inserted into the insertion hole (421b) to be spaced apart from the upper surface of the die (3). The lower surface is formed to a degree slightly wider than the distance to which the connecting member 410 is moved, and the rear side has a shape that is open without a lower surface.

Accordingly, the upper and rear surfaces of the fixing member body 421a into which the connection member 410 is inserted are provided with an upper surface finishing member 422 and a rear finishing member 423, respectively, to close the open upper surface and the rear surface, respectively, At this time, an adjustment member 430 is additionally formed on the opened lower surface.

The adjusting member 430 is provided in the inner space of the fixing member 420 as shown in FIGS. 6A and 6B, and is located on the lower surface side that is opened when the fixing member 420 is coupled to the die 3.

At this time, the height of the adjustment member 430 is lower than the height of the fixing member body 421 and can be moved up and down along the inside of the fixing member body 421, and this adjustment member 430 has a lower part of the upper surface through which it is coupled. The position can be adjusted in the vertical direction through the adjustment bolt 440.

First, the adjusting member 430 has a tapered surface 431 inclined downward on a surface facing the connecting member 410. In this case, the tapered surface 431 is inclined from an upper side to a lower side to form a shape having a lower surface area smaller than that of the upper surface. In this case, the tilt (x°) may be 1.5°, but is not limited thereto.

Therefore, the fixing member through the tapered surface 431 of the adjustment member 430, since it is necessary to adjust the direction in which the connection member 410 moves according to changes in the workpiece or punching through the adjustment member 430 The moving distance of the connecting member 410 interpolated to 420 can be adjusted. For example, when the moving distance of the processing unit 200 needs to be shortened, if the adjusting member 430 is moved upward and fixed, the moving distance of the connecting member 410 is also shortened, so that it can be adjusted through the adjusting member 430. I can.

In this way, it has the effect that it can be easily applied to punching processing having various reciprocating distances through the adjustment member 430.

The adjustment bolt 440 for adjusting the position of the adjustment member 430 described above has a bolt shape having a screw thread formed on the outer circumferential surface, and a part of the lower end is inserted through the hole 431 formed on the upper surface of the adjustment member 430, and the A hole 422a vertically extending the upper surface finishing member 422 at a position corresponding to the hole 431 is also penetrated.

At this time, a screw thread is formed inside the holes 422a and 431 described above, and is screwed together with the adjustment bolt 440 so that the adjustment bolt 440 can move in the vertical direction.

Therefore, the height of the adjustment member 430 can be adjusted through the rotation of the adjustment bolt 440 without the need to separately disassemble the lower fixing part 400 for adjusting the height of the adjustment member 430, through which the adjustment member ( The height of the 430) is adjusted so that the moving distance can be adjusted during punching.

In addition, the lower fixing part 400 is provided on the lower surface of the fixing member body 421a in the same manner as the guide part 500 described above, and a lower fixing protrusion 440 protruding in the downward direction is formed, and such a lower fixing protrusion 440 is the position of the lower fixing protrusion 440 among the places where the fixing member body 421a is first installed on the die 3 so that the die 3 and the fixing member body 421a can be more firmly fixed and coupled. A perforation work is performed to dig a groove by recessing it to correspond to the shape of the lower fixing protrusion 440 in a place corresponding to. Thereafter, the lower fixing protrusion 440 is inserted into the perforated groove to be fitted and fixed so that the fixing member body 421a can be firmly fixed to the die 3.

On the other hand, the upper through-shaft 130, the first and second through-shafts (320a, 330a), of the configurations that are through-coupled to the central through-shaft (340a), the coupling bracket (230) excluding the shaft coupling (111), the upper connector (311), the first and second connectors (320, 330), and the side connectors 411 are all bent to process the upper through-shaft 130, the first and second through-shafts 320a and 330a, and the central through-shaft 340a. It can be easily rotated according to.

In addition, the upper through-shaft 130, the first and second through-shafts 320a and 330a, and the central through-shaft 340a are provided with a closing member (not shown in the drawing) at both ends after they are penetrated and rotate frequently. Even in the intubated position, it can be prevented.

The punching mold mechanism 1 having the above-described configuration moves along with the elevating movement of the movable press 2 to punch the workpiece P, and an operation example of the punching mold mechanism 1 is described in detail with reference to FIG. 9. do.

First, (A) of FIG. 9 shows that when the upper fixing part 100 is vertically lowered while the movable press 2 is lowered at the maximum, the vertical moving shaft 310 is lowered in the vertical direction and the central bracket of the conversion part 300 (340) The lower surface is in close contact with the upper surface of the die 3, through which the first and second connectors 320 and 330 are extended to both sides around the central bracket 340, so that the processing unit 200 is provided with a workpiece. It moves horizontally to the side. Through this, the punch 220 moves toward the workpiece P provided in the die 3 to perform punching.

After the punching mold mechanism 1 performs punching, the movable press 2 gradually moves upward, and the upper fixing part 100 and the vertical moving shaft 310 are movable as shown in FIG. 9B. While moving upward together with the press 2, the first and second connectors 320 and 330 connected to the central bracket 340 rise in a form inclined upwards around the central through-shaft 340a.

Thereafter, as shown in (C) of FIG. 9, when the movable press 2 rises to the highest point and the press is completely opened, the vertical movement shaft 310 rises vertically, but due to the lower fixing part 400, the lower fixing part 400 ), the vertical movement shaft 310, the first and second connectors 320, 330, and the central bracket 340 are pulled toward the side in which the vertical movement shaft 310 is rotated around the upper penetration shaft 130 It is inclined toward the lower fixing part 400, and the second connector 330 rotates around the second through-shaft 330a and is inclined toward the side where the lower fixing part 400 is located, and the second connector 330 is pulled. The upper through-shaft 130 is also inclined toward the lower fixing part 400. In addition, the first connector 320 rotates about the central through-shaft 340a of the central bracket 340 moved upward so that the first connector 320 moves toward the lower fixing part 400.

Therefore, the first connector 320 rotates and moves toward the lower fixing part 400 around the first through shaft 320a, and the processing part 200 connected through it also moves horizontally toward the lower fixing part 400 Away from the workpiece.

At this time, the processing unit 200 is interpolated and penetrated into the guide unit 500 so as to be horizontally moved along the guide hole 510.

Therefore, when the movable press 2 rises, the punching mold mechanism 1 is driven in the order of (A), (B), and (C) of Fig. 9, and the movable press 2 descends to punch the workpiece. In this case, it is driven in the reverse order of (C), (B), (A) of FIG. 9 so that the processing unit 200 moves horizontally.

In addition, as shown in FIG. 10, the punching mold mechanism 1 installs a plurality of punching mold mechanisms 1 in one movable press 2 centering on the workpiece P as shown in FIG. The work efficiency can be improved by performing the punching process once.

Particularly, in the case of a workpiece having several grooves in the lateral direction, such as a cross-shaped driver bit, it is necessary to punch a number of times in the horizontal direction, but since it is punched four times in a single press operation, the manufacturing speed is fast and mass production is easy. Has the advantage of doing it.

On the other hand, since the above-described guide part 500 is applied to one punching mold mechanism 1, when the punching mold mechanism 1 is installed in multiple directions in order to perform multi-directional punching processing, the guide part 500 is also There is a discomfort that each is necessary.

In addition, when a problem such as loosening of one guide part 500 due to frequent machining occurs, a problem that it is difficult to perform the same punching process through a single press operation occurs, and each guide part 500 Additional problems such as insufficient space of the die 3 may occur due to the occupied area.

Therefore, the guide unit 500 that can prevent this problem is as follows.

As shown in FIG. 11, as another embodiment of the guide part 500, the body has a cylindrical shape 500a or a prismatic shape 500b, and a guide groove 510 into which each of the processing parts 200 is inserted is a side surface of the body. Is formed to be recessed toward the center of the workpiece (P) is formed to be recessed from the upper surface to the lower surface where the guide grooves 510 are located so that the guide groove 510 and the outside communicate with each other.

Therefore, a workpiece (P) is provided in the center where the multidirectional guide groove 510 and the outside communicate with each other, and the processing body 210 is installed in a state in which the processing body 210 is inserted into each guide groove 510. Moves along the guide groove 510 so that the workpiece P can be processed (see FIG. 12).

At this time, the guide part 500 is made of an integral type, and a plurality of punching mold mechanisms 1 can be firmly positioned and fixed by allowing a multi-directional punching process to be performed through one guide part 500. .

In addition, when punching is performed in six directions instead of four directions such as a hexagon wrench, the punching in six directions can be performed using the guide portion 500c in which six guide grooves 510 are formed.

Therefore, such a punching mold mechanism 1 can be combined with the lower surface of an existing movable press to perform punching in multiple directions on a workpiece fixed and positioned on a die, and can be easily combined so that it can be punched at a desired angle. , It is possible to have a plurality of punching mold mechanisms in one movable press, so that it is possible to perform a number of punching processing with one press operation, thereby improving work efficiency and preventing damage to the workpiece or occurrence of defective products. It has the effect of being able to.

Through this, it is possible to manufacture a workpiece having various cross-sectional shapes as shown in FIG. 13, and such a workpiece has an advantage that it can be used for a driver, a gear, a wrench, and the like.

In particular, the punching mold mechanism 1 according to the present invention is a forged mold type that performs punching on the workpiece P itself, rather than cutting and grinding the workpiece P, so that the strength of the workpiece P can be enhanced. The effect of obtaining a high-strength workpiece (P) can also be obtained.

On the other hand, what has been described with reference to FIGS. 1 to 13 above is a description of only the main matters of the present invention, and the present invention is not limited to the configurations of FIGS. 1 to 13 as various designs are possible within the technical scope. Is self-explanatory.
