Description

Cutting blade bending apparatus having one-touch type bending nozzle

The present invention relates to a processing apparatus for producing a cutting blade having a variety of precise bending form according to the shape of the printed material mainly provided for cutting a flat printed matter, in particular the cutting blade of the completed state is given a predetermined function In the metal piece plate provided to be provided, the metal piece plate may correspond to various conditions of the plate, for example, thickness and height, and the like, and may be variously required for smooth use of the cutting blade as well as bending work in various forms. The present invention relates to a metal plate processing apparatus for realizing a shape of a cutting blade having an improved function capable of realizing branch conditions in a desired shape through a single processing apparatus.

In order to produce so-called boxed packaging or plastic wrapping paper of synthetic resin including various flat printed matters, cutting is performed along the planar shape of the printed matter, or in the case of a three-dimensional article, After the development, a predetermined cutting operation is performed to separate only the finished product, thereby enabling various post-treatment operations.

In this case, in order to perform the cutting operation (hereinafter referred to as "cutting operation"), cutting blades having the same shape must be provided to correspond to the outer circumferential shape of the article deployed in a plane, and the cutting The blades are fixed to the wooden board on the plate so that the cutting blades face the outer surface while maintaining a close and even height width.The blades are then placed on a press to form a multi-layered (or single) piece of blood. The workpiece can be appropriately cut.

The cutting blade is made of a metal plate plate made of special steel on a thin plate, and is formed in the form of a cutting blade on the leading surface along the longitudinal direction while maintaining a very long length in a strip form, precisely according to the shape of the workpiece It is bent and planted on wood boards to provide additional detail and precision work processes.

For example, in order to maintain the shape of the wood board according to the wood board installation, the bridge groove formed by selecting the bottom of the cutting blade of the plate, the mold pressure for embossing forming, and the recess part by selecting the partial portion of the cutting blade to form a groove The marking not only prevents the workpiece from being completely separated from the surrounding fabric, but also marks the position point when it is to be bent by hand rather than bending grooves and mechanical bending, which are formed perpendicular to the side of the plate when a right angle bending is necessary in some cases. It should cover a wide variety of tasks and so on.

In addition, according to the expansion of the use of the cutting blade to form a plurality of grooves evenly at a predetermined interval (the interval can be operated variablely) on the cutting blade to apply it to the flat printed matter so that it can be artificially torn off by the user Of course, it can be configured.

Of course, this functionality itself is already in general use, but its production work is not uniformly uniform, it is partial, and the precision is very low because it is processed at that time as needed.

For example, by selecting only the most basic work process and separating the cutting edge formation, bridge groove, and bending process after the bending process, which are prepared in multi-steps, the workability and cost increase are caused. Problems have been included in the past.

Therefore, a long straight plate on a continuous line having already formed cutting edges is attached to the feed feeder, and then forcedly fed into the device of the automatic bending process sequentially and continuously, thereby contacting the bending pin at the tip of the bending nozzle to perform a predetermined bending process. It is a general processing equipment to be produced through.

As is well known, the bending process is already set in the computer control program according to the specific shape and the dimensions required, and thus the bending operation is performed according to the operation control method. It is located at the tip of the nozzle and finely rotates to the left and right by the above control signal to properly bend the plate discharged to the outside through the bending nozzle, which is already introduced by Japanese Patent Application Laid-Open No. 8-99123. It has been.

At this time, the metal piece plate is bent in a predetermined shape according to the mold, and the respective lengths are calculated and then cut into a plurality of pieces prior to entering the bending nozzle, and then supplied one by one or another As proposed in Japanese Patent Application Laid-Open No. Hei 8-243834, it is to be cut immediately after bending. As a specific means of cutting, the plate which protrudes to the front while being closely gripped on the nozzle is repeatedly repeated left and right. The method of bending and cutting by accumulation of metal fatigue degree were adopted.

However, according to the manufacturing process of the metal piece plate as described above, it can be seen that there are some fatal factors inherent in the production of high-quality cutting blades, providing diversity (multifunctional) and uniform and simultaneous processes are impossible.

In other words, the biggest problem is that it is not possible to properly produce a number of necessary functions to be included in the cutting blade through a single processing device through a continuous line.

On the other hand, even in the detailed process, the mold jig (which is not optional) whose size is uniformly fixed is fixed so that the formation of the bridge groove already maintains only a certain width. Since there is no simultaneous execution of the sewing process in one work line, it is inevitable to prepare a separate process, and thus involves another problem of burdening process loss.

In addition, when a plurality of guide bending pins are installed and the plate inserted therebetween is bent at a desired angle through intermittent rotation to the left and right, the complexity of the mechanical installation and precise angle adjustment are desired ( More specifically, the occurrence of an error in the case where a fine angle adjustment is required may be almost inevitable due to the deviation of the mechanical configuration.

In addition, in supplying a plate cut to a predetermined length in advance, a cumulative tolerance inevitably occurs between the respective cut plates, so that the bending itself on the bending nozzle is inevitably lowered in accuracy.

In addition, when any one of the plurality of guide bending pins are worn, it is difficult to accurately set the center, and in particular, when the two pins are not balanced, there is an operation problem that must be corrected individually.

In addition, the bending pin and the cutting blade of the plate is in contact with each other when bending, the risk of causing damage to the cutting edge is also very high.

However, above all, the cutting of the plate after the bending process is the most problematic. First, the cutting surface is not clean according to the non-momentary repeated bending operation of the left and right, and the burrs (protrusion surfaces of the metal pieces around the cutting surface) BURR) and so on, the appearance is remarkably poor, and accordingly, a finishing process, which is a surface reprocessing, is required. Second, the accuracy of cutting due to the calculation of fine dimensions is very low due to the occurrence of necessary tolerances during cutting. Occurrence involves a structural flaw that can only be tolerated.

Therefore, the formation and bending of the bridge grooves and the subsequent cutting process are sequentially performed on one line, and at the same time, the excellent surface treatment can be realized without the need for post-processing work according to the accuracy of fine angle adjustment and the cutting accuracy. Special attention should be paid to

In addition, it can cope with various sizes of the plate, and should be provided to perform various conditions required for smooth use of cutting blades as well as various types of bending work through a single processing device. .

To this end, the present invention allows the mold jig that can perform various functions to be detachable to enable the exchange and separation selection on the processing device, and also compatible use of each mechanical component to correspond to the size of the plate, etc. It was made possible, and thus it is an object of the present invention to provide a processing apparatus having an improved function so that it is possible to perform a variety of functions required according to the cutting operation of the cutting blade.

Of course, the processing apparatus provided by the above-mentioned object can provide a single or plural guide bending pins and promptly bounce them so that a quick bending operation can be achieved and the surface of the cutting surface can be kept very clean according to the instantaneous operation of the cutter. It can be maintained.

Therefore, the above-described improved function applied to the present invention can satisfy the strictly required precision while maintaining the operational speed, and ultimately, the economical benefit of improved workability can be improved. Has a purpose.

In this case, in order to set the left / right standby position of the cutter, the proximity sensor for confirming the last bending position of the plate and applying a predetermined signal may be provided.

Various preferred embodiments of the present invention may be more clearly reproduced through the following description with reference to the drawings.

1 is a perspective view showing the overall appearance of a processing apparatus that can be provided by one embodiment of the present invention, Figure 2 is a cross-sectional view showing the assembled state of the internal configuration of the processing apparatus of the present invention.

According to the present invention, the processing apparatus 100 of the improved function is first provided with a very long strip-shaped metal piece plate 1 in which a cutting blade is already formed as a raw material for the production of a cutting blade.

One side of the table 10 constituting the lower surface of the processing apparatus 100 is provided with a circular feed feeder 50 so that the metal piece plate 1 can be sequentially released while being squeezed to a sufficient length, The feed feeder 50 is addressed to the stepping motor 51 shaft which is presented as an example of the power generating means that exerts an intermittent driving force, so that the feeder 50 is sequentially rotated in one direction.

At this time, one or more feed feeders 50 may be installed in plural so as to maintain different rotation directions, and thus, even when the attachment direction of the plate 1 is different, it is possible to supply unreasonably. It is possible to enlarge the amount of the plate 1 that can be supplied according to the bar, which gives the advantage that it is possible to mount the plate 1 of different sizes (different conditions) in some cases.

Of course, each of the feed feeder 50 is a guide (2) acting as a guide pipe in front of the feed feeder 50 so that the plate 1 can be released in the specified direction even if the direction of rotational drive is different A plurality of plates 1 guide guide rollers 52 are disposed between the plates 1, and the plate 1, which emits only a predetermined dimension in an unscrewed band shape, is always considered to have a constant orientation.

Such a plate 1 is inserted into the guide 2 to be advanced by a predetermined length by the power of the above-described stepping motor 51, in which the proper position of the lower end of the cutting blade (not the upper end) (in one bending pattern The required number of formations is already selected) to form a space by opening one side of the guide 2 to an appropriate size to partially form the bridge groove 1a, thereby forming the outer bridge mold 20 and the like. This may be appropriately attached and detached, may be mounted through one side of the guide (2), or may be considered to open the upper one side of the outer case surrounding the outer circumferential surface of the guide (2) to fit from above to be fixed from above. Could be.

Of course, a plurality of the above space parts may be provided in close proximity to each other, and therefore, it will be well anticipated that external molds having different functions may be properly disposed and mounted.

In the case of the tip of the guide (2) in the role of the guide pipe, a pair of support plates (3) which can be mounted at the upper and lower positions facing each other are provided to constitute a part of the processing apparatus (100) main body. And a bending nozzle 4 which is tightly fitted in the insertion groove 3a formed between the pair of supporting plates 3 and can be fixed in a vertical position, is horizontally flush with the tip of the guide 2 described above. Will keep one straight line.

Therefore, the plate 1 having passed through the bridge die 20 described above is inserted through the forming hole 4a of the bending nozzle 4 and finally discharged to the outside. In this case, according to the specification of the plate 1 Of course, the bending nozzle 4 having a suitable sized opening 4a can be used interchangeably, and the support plate 3 used to support it can also be replaced accordingly.

At the tip of the bending nozzle 4, at one end of the bending nozzle 4 to bend the plate 1 sequentially discharged at an arbitrary angle by a separate numerical control program so as to maintain a constant bending pattern. (It maintains a distance very close to the nozzle.) The operation of the stepping motor 30 is carried out in the vertical direction, and the up / down driving is performed after the upper / lower parts are fixed to maintain the rigidity in the raised state. A single or a plurality of guide bending pins 31 intermittently rotated by the means are provided.

At this time, by selecting the proper position of the guide (preferably the beginning and the end of the guide is desired), also removable removable roller 60, 60a can be installed from the tip of the outer case. The pressurized rollers 60 and 60a serve to press the tip of the plate 1 at an appropriate pressure so that the supply of the plate 1 through the guide 2 is always performed under a constant horizontal height. do.

In addition, a guide rail 11 having a predetermined length installed in the vertical direction is installed at the left and right ends of the bending nozzles 4, and the telescopic operation is performed immediately upon receiving a predetermined bending process completion signal while being inserted in the center thereof. A first cylinder 41 is provided at the center of the upper end of the guide rail 11 and a conveying member 40 connected to the piston is provided, and the bending nozzle 4 is operated by the operation of the cylinder 41. It is possible to slide down from the straight end to the vertical state.

In the center of the lower end of the conveying member 40, a plate holder 42 having a width of approximately the same width as its thickness in the vertical direction is bolted to the center of the lower end of the conveying member in an exchangeable manner. Rotatingly coupled to the conveying member 40 while maintaining a very small gap in front of the plate holder 42, the position of the last bending angle of the plate 1 is detected (or under the control of a preset program). ) The cutter 43 is pivoted to an arbitrary position on the left / right side with respect to the axis engaged by the second cylinder 44 provided on one side of the conveying member 40, and the conveying member 40 moves downward. When the plate holder 42 completes the insertion of the plate 1, the groove 45 is formed at the end of the table plate 10 so that the end thereof may be tightly fixed so as not to flow by the cutting operation of the plate 1. It is formed, the groove portion 45 is formed in the front direction of the guide groove 46 in the horizontal direction, while the end of the cutter (43) waiting to be held on the upper side of the slide inserted into the engaging groove ( A moving piece 48 having a 47 formed therein is installed, and the cutter 43 is connected to a link that can be repeatedly operated toward the left / right side by being connected to the cylinder at the bottom of the body for forced movement of the cutter 43. The end of the fixed and at the same time to move rapidly to the left / right to cut the plate (1) of the completed bending state by the cutter 43 instantaneously.

Attached Figure 3 is applied to the processing apparatus of the present invention by sequentially pulling out the metal plate through the guide roller 52 in a plurality of feed feeders 50, the metal plate is already formed a blade (cutting blade) is formed A perspective view of the peripheral device for feeding into the processing apparatus.

The guide roller 52 is divided into a side guide 52a and an upper / lower guide 52b, and guides the plate 1 to be released from the feed feeder 50 into the guide 2 as it is. Play a role. At this time, the roller (52c) located in the middle of the side guide roller (52a) to move to the left and right to serve to correct the curved portion of the plate to be drawn out, and also in the upper / lower guide roller (52b) The roller 52d positioned in the upper portion moves up and down and serves to straighten the curved portion in the vertical direction of the plate to be drawn out.

Figure 4 is an exploded perspective view showing one embodiment of the bridge mold detachably coupled to the guide of the present invention, Figure 5 (A) and (B) is a plan view of the bridge mold jig used in the prior art. 6A and 6B are exemplary views schematically illustrating the internal cross-sectional structure of the bridge die according to the present invention.

As described above, the mold jig 21 of the present invention is minimized in fluidity due to the fact that the protruding surface 21a of its tip is pre-fitted on the guide path 20a in the mold 20, and then the bridge is minimized. In the case of rapidly advancing inward by the external force to form the groove 1a, it slides in one direction toward the inclined surface and falls off from the wall surface of the guideway 20a, thereby significantly lowering the wear rate, thereby improving durability. Can be.

However, according to the conventional mold jig shape, when only one surface of the inclined surface is inserted or not at all on the guide path (20a) when the slide is pushed to the outside pressure is severely rubbed with the wall surface is worn or broken As a case has arisen, long-term use is practically impossible.

The bridge mold 20 having such improved performance can be installed by appropriately replacing the retaining jig 21 having a wide variety of sizes depending on the width of the bridge groove (1a) desired, the small jig Using the 21, the bridge groove 1a of the plate 1, which is intermittently moved by hitting repeatedly using external power while repeatedly moving the plate 1 finely, can be widened.

7 (A) and (B) and (C) illustrated are various types of plates that can be produced by the respective molds including the bridge molds, and this processing method is called a sewing process. As described above, the cutting edge portion of the plate 1 can be processed to the groove 1b to a predetermined width by using one mold jig.

For example, a processing method in which a plurality of perforations are formed in a straight line shape adjacent to a printed paper surface in order to remove only a portion required by a user may be embodied through the above sewing process. High frequency of use and the like, the spacing of the other space can be adjusted by repeated hitting of the mold jig as described above.

On the other hand, the bent groove processing apparatus for forming the groove portion and the right angle bending of the plate (1) should be provided, which is the groove portion and the bent groove using the grinder and the bite provided separately as shown in Figs. The purpose of formation can be achieved.

In addition, FIG. 10 is a plan view of the plate bent at a right angle according to the formation of the bent groove that can be formed through the means, Figure 11 illustrates a groove formed at a suitable interval on the blade plane of the plate.

According to this, a plurality of grooves 1c are formed at the tip of the cutting blade so that a predetermined distance can be maintained, so that the cut product is positioned on the peripheral base by the position of the grooves 1c and the width of the grooves 1c. By maintaining the connection with the base (mainly sales and storage prior to delivery to the consumer), it can be finally torn off and used by the user as needed. This is to avoid the hassle of selling or storing the printed sheets one by one. There is an advantage that can be properly resolved, and in such a plate 1, when bending at various angles including an acute angle and an obtuse angle is desired, one side along the short axis direction (vertical direction) height of the plate 1 is desired. By forming the bent groove (1d) perpendicular to the instantaneous, the bent groove (1d) can be maintained in a state bent at the correct angle with respect to the reference point.

That is, one end of the guide 2 is cut out to expose the plate 1 to be moved while being inserted through its inner surface to the outside, and an up / down cylinder 70 is installed on the upper end thereof, and the cylinder ( The stepping motor 71 is installed on the piston shaft of 70) and can be driven by a power shielded according to an up / down operation. The stepping motor 71 has a predetermined thickness and width that can be driven while being installed on the stepping motor 71. Since the grinder 72 is exposed, it is possible to form the bent groove 1d on the side as well as the groove 1c on the top of the plate 1 in the state exposed to the outside.

The support member is provided so that the up / down cylinder 70 can be positioned directly on the upper end of the separated guide 2 while being integrally formed with the table 10 of the base toward the separated one end of the guide 2. It is provided below 73, and is considered to be able to operate according to an internal control program.

At this time, the stepping motor 71 is fixed in a direction perpendicular to the piston shaft, the shaft is installed in the stepping motor 71 is driven while maintaining a predetermined depth and width while maintaining a predetermined interval on the upper end of the cutting blade It is to be able to form the groove portion (1c) in the portion and at the same time to be formed in the inner surface along the short axis direction the bending groove (1d) that is already defined in the position to be formed.

On the other hand, it is also possible to replace the grinder 72 to install a mold (not shown) that can correspond to the shape of the groove portion (1c) can be operated separately from the processing of the bending groove (1d) will be.

In addition, the up / down cylinder 70 is installed at the lower end of one side of the separated part of the guide 2, and the bite according to the up / down operation of the cylinder 70 by vertically installing the bite 74 at the front thereof ( It is also preferable to form the bent groove (1d) by 74).

12 (A), (B), and (C) are conventional examples showing that the lower surface of the plate is deformed by marking the lower surface to indicate a position point when the plate is curved. FIG. Exemplary state of use of the marking mold jig provided to enable the marking operation by the invention.

Marking work is to mark the bending position point during the bending work of the plate (1), for example, the fine and fine bending process is finally manual work so that mechanical bending process is impossible, the bending point is also bending work Elastic means in the inner surface through a plurality of pairs of mold jig (80, 80a), which is previously calculated along the numerical control shape and is also detachably provided and is instantaneously moved by the cylinder on both the left and right sides of the plate (1). By pushing the pin which is always maintained in one direction by the cylinder to form a bending point on the upper and lower sides of the plate (1).

However, conventionally, as shown in the drawings, by using a single mold jig to form a marking groove on one side of the bottom surface of the plate 1, when the marking grooves are concentrated while maintaining the mutual distance, the lower end portion is damaged and falls off. As there was a significant risk of occurrence of outward or severe distortion, it could be formed by selecting the upper / lower side (each formed at the center part with a certain distance from the outermost side) of the side of the plate 1 as an appropriate improvement. There is an advantage.

FIG. 14 is a perspective view showing an external configuration of the bending pin, and FIG. 15 is an enlarged plan view of the configuration of the bending pin, and FIG. 16 is an assembly configuration according to the actuating operation state of the bending pin. 17 is a cross-sectional state diagram shown and an exemplary state of operation of a bending pin fixed to and raised.

The bottom part table 10 of the bending nozzle 4 which is the straight end of the guide pipe guide 2 is formed with a space portion 12 of a circular shape (regardless of shape but preferably a circular shape). A first gear portion 33 is provided which is positioned in the bearing 32 so as to be freely rotated in place on the lower surface of the straight surface 12. The upper end portion of the bending nozzle 4, which is the upper end portion thereof, is correspondingly opposed thereto. In the form of a saw, a second gear portion 33a, which is also fitted to the bearing 32a, is provided.

An insertion hole 33b is formed at one side surface of the first gear part 33 and the second gear part 33a facing each other, and is inserted into the insertion hole 33b of the first gear part 33. The bending pin 31 is positioned so that the lifting and lowering is free, and the semicircular pin protection guide 29 is integrally protruded to one end of the outer circumferential surface of the insertion hole 33b (to be formed in accordance with the height width of the plate). In the continuous bending operation, it is possible to prevent the bending end of the bending pin 31 and the closed end such as breaking.

In addition, the semicircular pin protection guide 29 formed of the insertion hole 33b into which the bending pin 31 is inserted and one end of the outer circumferential surface thereof may be installed in single or multiple numbers according to the number of bending pins 31 installed. In this case, the bending pin 31 of an appropriate size may be selectively used depending on the degree of plate bending or the thickness or height of the plate material, thereby making it easier to perform the plate bending process.

When the bending pin 31 is formed in plural numbers, the number is preferably 2-4.

In particular, the planar cross-sectional structure of the bending pin 31 maintains the curved round shape in a convex shape toward the outside, and the inner surface has a slightly concave shape, so that the portion in contact with the bending surface of the plate 1 is convex. Arrange so that the edge of the concave surface.

In addition, the corner portion is provided with a depression 31a for maintaining a proper distance, which is located at the top as well as the lower end of the cutting edge of the plate 1, resulting in protrusions other than the depression 31a. This part is in close contact with the middle part of the plate 1 and finally pushed (by rotating) to prevent damage to the cutting edge due to bending.

Along with this, there is an advantage in that the center setting is easy without the bias of the force occurring.

Since the lower end of the bending pin 31 is connected to the cylinder 34 piston in a fixed state with the lower end of the first gear part 33, the lower end of the bending pin 31 is vertically positioned through the space part 12 at the tip of the bending nozzle 4. It can be sufficiently indented operation, the tip is fitted to another insertion hole (33b) located at the top at the same time to maintain the firm fixed state.

At this time, if a deviation occurs in the position of another insertion hole (33b) located at the top to move the gear box in which the second gear portion (33a) is installed in the front / rear, left / right to correct this Accurate centering is possible.

For the left and right rotational movement of the bending pin 31, the first and second gear units 33 and 33a described above are stepping motors on the bottom surface of the processing apparatus 100 so as to be interlocked at the same driving ratio. 30) The plurality of drive gears 35 and 35a fixed to the shaft are connected to each other by a belt, and the rotational force control of the stepping motor 30 and the driving of the cylinder 34 are due to the control of a preset program. Do.

That is, the bending pin 31 which protrudes so that the plate 1 discharged | emitted through the guide 2 in some predetermined form may be adjacent to the front-end | tip of the bending nozzle 4, and the 1st, 2nd gear part 33 ), (33a) is rotated at the same time to smoothly adjust the angle of the plate (1), in the case of bending by changing the bending direction, the raised bending pin 31 is lowered to the right and left of the plate (1) By repositioning and repositioning, continuous repetitive work is possible.

Meanwhile, as shown in FIG. 16, the bending pin 31 has a plurality of bending pins 31 having a proper size according to the bending angle of the plate 1 or the thickness and height of the plate material. It is provided to be used alternately. Thus, in order to bend the plate 1 discharged from the tip of the bending nozzle 4 into various shapes, a first bending pin 31 having a predetermined size is firstly selected, and the vertical direction on one side of the tip of the bending nozzle 4 is selected. After performing the bending operation by bending, the used first bending pin 31 is lowered, and then the second bending pin (not shown) or the third bending pin (not shown) is again set by a predetermined program. It is selected and subjected to the same processing as the first bending pin 31.

At this time, the adjustment of the distance α between the bending nozzle 4 and the bending pin 31 is adjusted according to the thickness of the plate 1 due to the removable bending nozzle 4, for example, when the plate 1 is rather thin. In the following, the bending nozzle 4 is advanced to narrow the gap width, and when the thickness is very large, the gap width needs to be relatively wide. For this purpose, the bending nozzle 4 can be retracted by a predetermined position. The overall assembly structure of the bending nozzle shown in FIG. 18 can be understood through a side view showing the tip of the processing apparatus provided with the bending nozzle of FIG. 19.

20 is a block diagram showing a front surface of a processing apparatus in which a plate holder and a cutter are installed to fix and cut a metal plate discharged through a bending nozzle in the present invention, and FIG. It is a block diagram which shows the enlarged action state of a plate holder and a cutter.

Hereinafter, the cutting operation of the bent plate is described in more detail.

As described above, the plate 1 in a state where the bending operation is completed is continuously advanced and positioned at the front of the table 10, and at the same time, the bending of the plate 1 in the final left / right direction is completed in accordance with the completion of the above-described bending operation. The cutter 43 is provided so as to be moved in advance to the position necessary for cutting of the plate 1, which is a pre-stage position of the completed cutting blade, by applying the state in advance by the pattern operating program, and the cutter 43 is A conveying member inserted into the guide rail 11 so as to easily slide up / down by the operation of the first cylinder 41 which is upwardly protruding from the tip of the bending nozzle 4 toward the front ( The shaft is installed to allow left / right rotation with the lower surface of 40).

At the lower end of the transfer member 40, a plate holder 42, which can be detachably attached to the plate 1, can be fixed while protrudingly fixed from the top, and FIG. 23 shows a plate holder having such a role. Is shown in perspective view, and FIG. 24 illustrates its cross-sectional view.

The plate holder 42 is composed of a pair provided in a mutually symmetrical shape so that a gripping groove 42a of a size suitable for the thickness width of the plate 1 can be provided.

That is, the gripping grooves 42a are formed by processing the inner surfaces of the plate holders 42 that are separated from each other, and the gripping grooves 42a are formed in the form of passages when the pair of the gripping grooves 42 are fixed to face the inclined top. The inner surface of the upper end is triangular due to the mutually inclined surface, so that the cutting edge of the triangular shape is fixed while being accurately inserted, thereby preventing the cutting blade from being broken, thereby replacing the bending nozzle 4. Poetry is characterized by being exchanged together integrally.

In addition, the lower end of the holding groove 42a is extended toward the outside to maintain a somewhat open state, which is the front end of the plate 1 discharged through the bending nozzle 4 and the center of the plate holder 42 Even if it does not coincide, the tip of the plate 1 is naturally considered to be immersed.

Thereafter, as shown in (A) and (B) of FIG. 27, a cutter 43 is moved in advance by the second cylinder 44 to a position necessary for cutting the plate 1 and waits. This is downward while being very close to the front of the plate holder 42 as described above, the movable piece 48 located on the front surface of the groove portion 45 at the tip of the table 10 is also integrally horizontally moved to the locking groove 47. Cutter 43 end of the upper portion of one side is bite is fixed firmly.

Therefore, the cutter 43 is connected to the cylinder at the lower end of the body so as to be forcedly moved along the guide groove 46 in the horizontal direction from the front of the groove part 45 and repeatedly operated toward the left / right sides. The plate 1 is firmly cut at the desired dimension, and the left / right rotation for waiting of the cutter 43 confirms the bent final position of the plate 1 and applies a predetermined signal. Of course, it is also possible by the proximity and the photo sensor.

At this time, as shown in the perspective view of the cutter shown in FIG. 25 and the front state diagram shown in FIG. 26, the inclined surface 43a which maintains a predetermined angle β on both sides so as to be cut from the lower surface of the plate 1. By forming the lower side of the upper side of the lower edge of the cutter 43 is widened to the first contact with the side of the plate (1) to be lifted from the bottom to prevent damage to the cutting blade.

That is, when the plate 1 is cut from above, the plate 1 is forced downward on the plate holder 42 at the same time as it is cut (by being pressed), so that the angle of the blade does not match, and the plate holder does not fit. Healing a fatal defect that 42 cannot be supported and eventually cut in an oblique direction. When cut from the bottom, the plate 1 rises upside down but prevents further rise by the plate holder 42. It can be cut cleanly without difficulty.

On the other hand, Figure 28 is an exemplary view showing that the cutting blade discharged through a series of manufacturing process as described above is installed and fixed on the wooden board, wherein the cutting blade is installed in one direction and another cutting blade in a perpendicular direction to each other When tightly fixed and fixed, the tapered surface of the cutting blade causes gap tolerance. To prevent this, select the height of the cutting blade part of the cutting blade fixed in the right angle to protrude the tapered surface. It is obvious that the cutting edge can be maintained in a perpendicular direction of the cutting edge without any gap clearance by close processing.

As described above, the metal plate processing apparatus for realizing the shape of the cutting blade of the present invention is mainly provided for cutting the printed material is a processing device for manufacturing a cutting blade having a variety of precise bending form according to the shape of the printed material It can cope suitably with various conditions of the plate, and can realize various conditions required for smooth use of cutting blades as well as bending work in various forms in a shape desired by a user through a single processing device. have.

In addition, from the supply of plates to the final cutting process and the cutting edge of the cutting edge can be precisely performed through a single process line, the economical useful value provides a great advantage.

On the other hand, the present invention exemplified the best embodiment thereof, but is not limited thereto, and may be considered without departing from the scope of the present invention if limited to the appended claims may be considered a modification of the embodiments described so far.
