Here, the transfer part 21 is a part that serves to feed the strip in a step-wise manner into the press mold part 15, the press mold part 15 serves to process the strip through the press operation. Means.

In addition, the machine room 11 has a front part designed as a door, and the side part and the rear part have a form of a removable cover in order to increase accessibility related to assembly and maintenance of a drive unit, a servo motor, and the like of the driving unit.

In particular, when the vibration of the mechanical equipment is applied, the structural material is damaged, or if the vibration of the structure is large, the degree of the manufactured object is bad, so it is necessary to appropriate measures in terms of vibration reduction or vibration isolation.

To this end, the main body 12 is provided with four rubber air springs 44, one each disposed at the bottom four corners, and each rubber air spring 44 supports the four corners of the body 12 in a balanced manner. By giving, the main body 12 can have a dustproof structure that can cope with vibration actively.

Here, the rubber air spring 44 is a high-efficiency air spring dustproof mount combining rubber and air viscous damping, which is excellent in dustproof efficiency and serves to effectively isolate vibration from the main body 12.

In addition, the main body 12 is provided with a protection device 45 for the pumping operation type protection device, that is, the equipment is operated by pressing both pushbuttons with both hands as the protection means, and the press mold unit 15 and the transfer unit 21 Since the safety cover 46 is installed in each, it is possible to prevent the hands or handling tools, etc. from entering the work space inadvertently by the operator during operation.

Here, reference numeral 47 denotes a rail for unloading the strip after pressing.

2A to 2C are perspective views illustrating a press die part, a driving part, and a transfer part of a connector terminal high speed machining press according to an embodiment of the present invention, and FIG. 3 is a press die of a connector terminal high speed machining press according to an embodiment of the present invention. It is sectional drawing which shows a part, a drive part, and a conveyance part.

As shown in Figs. 2A to 2C and Fig. 3, the transfer part 21 is a means for transferring the strips step by step to the press working area, and is located in front of the press die part 15 so as to drive the servo motor as a drive source. It serves to inject the strip into the press mold unit 15 by an electric motor using a cam, and includes a clamp 19 that operates vertically and a gripper 20 that operates vertically and horizontally.

To this end, a conveying part frame 36 in the form of a box-shaped structure is installed inside the machine room 11 in the main body 12, and a conveying shaft is provided on the front and rear walls of the conveying part frame 36. Both ends of (37) are installed in a rotatable structure via a bearing.

Three cams 38a, 38b, and 38c which are positioned at regular intervals along the longitudinal direction of the shaft are provided on the feed shaft 37 thus installed.

Then, one side of the transfer part frame 36 is provided with a transfer motor 34, ie a servo motor, supported on the motor bracket 48 provided on the bottom surface of the base 10. The shaft 34 and the feed shaft 37 of the 34 are connected to each other by the belt transmission 35 so that power can be transmitted to each other.

That is, the pulley is mounted on the shaft of the transfer motor 34 and one end of the transfer shaft 27, respectively, and the belt is caught between both pulleys at this time, so that the driving force of the transfer motor 34 is the belt. The transmission shaft 27 is rotated while being transmitted through the transmission 35, and can eventually lead to rotation of the cams 38a, 38b, and 38c.

A gripper 20 and a clamp 19 are provided as a means for substantially holding or fixing the strip, and the gripper 20 and the clamp 19 are positioned back and forth to transfer the strip one step and to fix the strip. The role is to give.

That is, the gripper 20 serves to transfer the strip in the direction of progress while moving up and down and moving forward and backward, and the clamp 19 fixes the strip during press working. It will play a role.

The operation of the gripper 20 and the clamp 19 is made by sliding with the cams 38a, 38b, 38c on the feed shaft 27.

To this end, a gripper rod 41 which moves up and down while engaging the cams 38b and 38c in the feed shaft 37 and rollers 39b and 39c at the bottom contacting the rolling shaft 37 is coupled to the bottom of the gripper 20. At this time, the rollers 39b and 39c in the gripper rod 41 come into contact with the rolling surfaces of the cams 38b and 38c that rotate, thereby raising and lowering the gripper rod 41 and further moving forward and backward. This is achieved, and as a result, the strip can be transferred while the up and down, forward and backward operations of the gripper 20 integrally coupled with the gripper rod 41 are made.

For example,

In addition, the clamp rod 40 which moves up and down while having the roller 39a at the lower end in contact with the cam 38a on the feed shaft 37 is also coupled to the bottom surface of the clamp 19, and the clamp at this time The rod 40 is raised and lowered while sliding with the rolling surface of the cam 38a which is rotating by using the roller 39a at the lower end, so that the clamp 19 which is integrally coupled with the clamp rod 40 is eventually obtained. Rise and fall operations can be achieved.

As such, by using a dedicated cam for each operation such as clamp up / down transfer, gripper up / down transfer, gripper front / rear transfer, and the like, a transfer means capable of high-speed rotation can be realized.

In general, the high speed operation was not possible in the existing domestic gripper feeder, because the feed amount of the material is adjusted to 0 ~ 20, 0 ~ 50 or more. Material transfer becomes impossible.

With this in mind, the present invention can implement a transfer unit suitable for high speed by limiting the adjustment amount to 0 to 10 according to the characteristics of the equipment.

For example, the present invention can be applied to the VG15H model capable of material transfer at a speed of 2000spm, the VG15H model is capable of material transfer of a distance of 0 ~ 15mm and the maximum feed rate is up to 3600spm, which is provided by the present invention In the case of the 3001 FPC contactor mold, which is the product to be processed, the material can be operated by setting the material feeding distance to 4.6mm and the feeding speed up to 2400spm.

The drive unit 16 is provided in the machine room 11 formed under the main body 12, and is a means for operating the press die unit 15 by using the drive motor 13 and the drive unit 14, In order to facilitate high speed operation in a compact structure, it has a structural feature that can minimize the amount of up and down feed.

To this end, a drive motor 13, that is, a servo motor, which is a driving source is provided, and the drive motor 13 at this time is installed on the drive frame 22 having a rectangular box shape installed on the bottom of the base 10.

In addition, a drive unit 14 is disposed in front of the drive motor 13 to substantially move the movable punch set 17 of the press die portion 15 up and down, and at this time, the drive unit 14 Is connected to the driver motor 13 side and the coupling means to receive power.

The drive unit 14 is an eccentric shaft 23 rotated by the drive motor 13, a connecting rod 24 for converting the rotational movement of the eccentric shaft 23 into a vertical linear movement, a movable punch set 17 ) And a connecting plate 26 connected to the side.

The eccentric shaft 23 is a kind of crankshaft, which is positioned side by side along the axis of the drive motor 13 and supported at both ends in a rotatable structure on the drive frame 22 via a bearing, and one end thereof. Is connected to the shaft of the drive motor 13 via a coupling.

At this time, the bearing used as the support means of the eccentric shaft 23 can be applied to the roller roller bearing having a strong characteristics in high-speed rotation and vibration resistance and impact resistance.

The connecting rod 24 is composed of a pair, is coupled at a predetermined interval on the eccentric shaft 23, the coupling portion with the shaft is interposed a bearing such as a cylindrical roller bearing, the eccentric shaft 23 It can be reciprocated up and down by the rotation of.

The connecting plate 26 is formed in a "c" shape, and the thickness is penetrated at the same time as the upper end of each connecting rod 24 in the form of a penetrating through the horizontal posture, the coupling portion of the connecting rod 24 at this time At the same time a bearing such as a needle bearing is interposed, the connecting pin 49 is horizontally fastened.

In addition, vertically mounted rods 25 are respectively installed at four corners of the upper surface of the connecting plate 26, and each rod 25 penetrates the fixed die set 18 in the press die 15. After extending to the upper side, it is coupled to the bottom surface of the movable punch set 17 by a bolt fastening structure.

In this case, a bush is interposed between the rod through portions of the fixed die set 18 to guide the vertical movement of the rod 25.

As the four rods 25 are connected between four corners of the movable punch set 17 and four corners of the connecting plate 26, the connecting plate 26 and the movable punch set 17 are driven together. In turn, the press working on the strip can be accomplished by the vertical press operation of the movable punch set 17.

That is, the power is transmitted in the order of operation of the drive motor → rotation of the eccentric shaft → connecting movement of the connecting rod → vertical movement of the connecting plate and the rod → vertical press operation of the movable punch set.

In particular, in the case of the drive unit 14 provided in the present invention, since it is located at the lower portion of the press mold part 15, there is provided a means for preventing the drive unit 14 from being affected by scrap discharged downward. do.

That is, the scrap chute 43 is installed at the bottom of the press mold part 15 at the bottom of the base 10, that is, at the bottom of the position where the scrap is discharged after press processing, thereby collecting scraps and interfering with the drive unit 14. A circular tube is extended to the inner space portion of the connecting plate 26 which is not in the shape of, for example, a "c" shape, so that the scrap can be discharged by the suction force.

In addition, in the ascending state of the mold (punch set) of the press die part 15, since a lot of air is introduced from the outside, a smooth suction action is performed. It is not possible to escape through the round tube and float in the chute, which may eventually be a cause of scrap rise and scrap clogging.

As a countermeasure against this, an air control plate 42 is installed in the scrap chute 43 to prevent the instantaneous vacuum occurring when the mold is lowered, thereby maintaining a certain amount of air entering from the outside.

The press mold part 15 is installed on the base 10 of the main body 12 toward the rear of the transfer part 21, and the upper movable punch set 17 and the lower fixed type which are operated up and down by the driving part 16. The die set 18 serves to machine the strip.

To this end, as shown in FIG. 4, the movable punch set 17 and the fixed die set 18 are formed as a mold means for performing a press working on a strip which is disposed up and down, and which advances therebetween. The die punch set 17 is supported by the rod 25 extending from the drive unit 14 of the drive unit 16 and moves up and down, and the stationary die set 18 is fixedly installed on the base 10. .

The movable punch set 17 is provided with a punch holder 29 in which a plurality of punches 28 for strip processing are mounted, and the fixed die set 18 has an angle in the punch holder 29. A die holder 27 having a punch hole corresponding to the punch 28 is provided.

At this time, the punch holder 29 and the die holder 27 are arranged in parallel with the traveling path from above and below with the traveling path of the strip in between.

In particular, the strip plate 31 is provided as a means for stably holding the strip during the press working of the punch 28, the bottom plate of the strip plate 31 is equipped with a strip holder 30 that substantially presses the upper surface of the strip. do.

At this time, the strip holder 30 is also arranged side by side along the traveling path of the strip.

These strip plates 31 are arranged side by side with appropriate spacing between the movable punch set 17 and the stationary die set 18, and are supported by a rod 25 passing through four corner portions. Is installed.

That is, it may be installed in a structure that is elastically supported by a spring (not shown) mounted around the rod 25 while contacting the top and bottom surfaces of the strip plate 31.

Accordingly, when the strip is seated on the die holder 27 of the fixed die set 18, the movable punch set 17 is lowered by the operation of the driving unit 16, and with this the movable punch set ( The strip plate 31 at the bottom of the 17 is pressed to pre-contact and fix the strip while the punch 28 in the punch holder 29 of the movable punch set 17 strikes the strip. Thus, the press working on the strip is made.

In particular, the present invention provides a new type of punch means to prevent the scrap from rising during strip press processing.

For example, when the punch 28 has a circular shape, the scrap according to this is also a garden, and when the roughness of the straight land booze of the die is high, it can be easily rotated or stuck close by the oil in the die without being caught by the die.

In order to solve this problem, as shown in FIG. 5, by forming the protrusion 32 on the lower edge portion of the punch 26 as much as the thickness of the strip, the scrap is artificially stretched at the time of punching so that the scrap is placed on the die side. Induced to be pinched.

More preferably, by processing a micro groove, such as a barrel wire, in the straight land portion of the die side to modify the shape of the scrap of the garden, it can be more surely caught in the die to prevent the scrap from rising. do.

6A and 6B, the die holder 27 of the fixed die set 18 is provided with an air hole 33 in communication with one side of the passage 50 through which scrap is discharged, thereby providing a flow of air. Through the discharge of the scrap can be made smoothly.

Accordingly, by processing a hole through which air can flow in the scrap discharge direction to create a strong flow of air during the operation of the suction device, it is possible to smoothly discharge the scrap to prevent the rise of the scrap and clogging phenomenon.

For example, as a countermeasure for high speed operation, oil is directly drawn from the upper part of the mold to smoothly supply the oil, so that oil is caught between the scrap and the scrap when punched, and belongs to the punch holder 29. Problems that occur in some punches of the punch 28, that is, the shape of the scrap is not only small, but also the nature of the narrow width and the longitudinal direction is easily entangled, there is a problem that the scrap can be blocked in the straight land.

As a countermeasure against this, a hole through which air can flow was processed to smoothly discharge the scrap. In this case, the die may be inclined to enter a vertical straight land portion, or the die may collapse when processing with diagonal lines when the other invention is thin and long. As a result, the die can be machined in a horizontal direction with the top of the die so as to match the end of the straight land.

In addition, a water tank (not shown) is formed on an upper surface of the strip holder 30 of the press mold part 15, and when oil is directly supplied from an upper portion of a mold (movable die set), the oil is contained in the water tank. In this case, the fuel oil can be continuously supplied during the slide, thereby effectively discharging the frictional heat and the fuel heat of the slide surface, so that a high speed operation of 2000spm is possible.

On the other hand, the present invention provides a new type of equipment control system suitable for high-speed press work.

In order to be able to perform high-speed presses, synchronization between the servo axes must be a very important part.

The equipment of the present invention is composed of a main servo motor (drive motor) for driving a press and a feeding servo motor (feed motor) for conveying materials, and the rotation ratio of the material conveying device selected to achieve a speed of 2000spm is 1: Since 3, the rotation ratio of the main servo motor and the feeding servo motor is 3: 1.

Therefore, timing unbalance is likely to occur if the synchronous operation control system is unstable between start / stop.

In view of this, the present invention provides a method of operating the control system in a synchronization manner based on a virtual axis.

In this method, in order to prevent the current position deviation of each axis from increasing as the speed that becomes a problem in the way that the feeding servo motor follows the position of the main servo motor, the PLC gives the operation command to the virtual axis, and each servo This is how the motor follows the position of the virtual axis.

In this case, the virtual axis is rotated at a specified speed, and the axis has the effect of reducing the current position deviation in the high speed operation by simultaneously giving the respective axes a synchronous command to the virtual axis.

As a result of checking the current position of each axis every 2ms at 2000spm, it was confirmed that an error value without any problem in the operation of equipment up to about 0.1deg occurred.

Therefore, looking at the operating state of the connector terminal high-speed processing press is configured as follows.

7A and 7B are cross-sectional views illustrating an operating state of a connector terminal high speed machining press according to an embodiment of the present invention.

As shown in FIGS. 7A and 7B, the strip 100 supplied in an uncoiler manner is operated to raise and lower the clamp 19 and the gripper 20 of the conveying part 21 located at the front end of the main body 12. And forward and backward by one step by forward and backward operations, and the strip 100 is moved in a continuous manner in the working area of the press die portion 15, that is, the movable punch set 17 and the fixed die set ( 18) is introduced into the area to be formed between.

When the strip 100 is seated and positioned in the work area of the press die part 15, the drive motor 13 of the drive unit 16 is operated to operate the eccentric shaft 23 of the drive unit 14 and the connecting rod 24. And the connecting plate 26 are linked to each other, and the movable punch set 17 of the press die portion 15 connected thereto by the lowering of the connecting rod 24 and the connecting plate 26. At the same time, the punches 28 in the punch holder 29 of the movable punch set 17 at this time hit the strip 100, so that the press working on the strip 100 is performed.

At this time, the one-time punching process for the script 100 is a one-time lowering of the entire movable punch set 17 including the connecting rod 24 and the connecting plate 26 according to one rotation of the eccentric shaft 23. This is accomplished by a lift operation.

Subsequently, when the punching is completed once for the strip 100, the strip 100 is moved forward one step again by the transfer unit 21, and the above-mentioned punching process is repeatedly performed, thereby providing high-speed continuous automation. The process allows the strip to be pressed.

As described above, in the present invention, by constructing a new type of high speed processing press that organically combines the conveying part and the press mold part of the upper part of the equipment and the driving part of the lower part of the equipment, it is possible to simplify the structure and reduce the size of the equipment and to apply the efficient operation mechanism. There is an advantage that can improve productivity and quality, such as dramatically increasing the speed.
