The configuration of such a conventional material setting apparatus is shown in FIGS. FIG. 6 is a plan view of a conventional lower mold, and FIGS. 7A and 7B are cross-sectional views showing two examples of a conventional material setting apparatus.
In these drawings, 100 is a lower mold, 102 is a lower die set plate, 104 is a lower backing plate, and 106 is a die plate. The die plate 106 is fixed to the lower die set plate 102 via the lower die backing plate 104, and a plurality of dies (not shown) are attached corresponding to the pressing process. The hoop material 1 is fed in the direction of the arrow shown. Reference numeral 110 denotes a material guide lifter device that feeds and lifts the workpiece 1 and includes a plurality of guide pins 110a and a plurality of lifter pins 110b that can freely enter and exit. These pins 110a and 110b are provided so as to freely enter and exit the die plate 106 via springs 110c that are biased in the protruding direction. A guide groove 110d for guiding the side edge of the workpiece 1 is provided at the upper end of the guide pin 110a. 120 is a material setting device.
[0004]
In the example shown in FIG. 7A (hereinafter referred to as Conventional Example 1), the conventional material setting device 120 includes a material positioning pin 121 and a spring 122 that pushes up the material positioning pin 121. The spring 122 is always attached so as to protrude on the die plate 106. The material positioning pins 121 are arranged at substantially the center of the row of guide pins 110a and lifter pins 110b on both sides, and are arranged at the rear of the first step of press working. Further, the material positioning pins 121 protrude at substantially the same height as the guide pins 110a.
[0005]
In Conventional Example 1, the workpiece 1 is inserted along the guide grooves 110d of the guide pins 110a on both sides until the tip contacts the material positioning pins 121. After positioning, the upper die (not shown) is lowered, and the workpiece 1 is pushed down together with the guide pins 110a, the lifter pins 110b, and the material positioning pins 121 by the upper stripper plate, and the workpiece 1 is subjected to the first step (lead holes, etc.). ) Is pressed. In the second step, the operator pushes down the material positioning pin 121 using a bar or the like to sequentially feed the workpiece 1 and then performs the pressing in the second step. Thereafter, the workpiece 1 is manually fed sequentially until the final process, the workpiece 1 is passed through the material guide lifter device 110, and then the progressive press is started automatically.
[0006]
7B, the material positioning pin 121 is engaged with the cam portion 124a of the lever 124 through the knock pin 123. In the conventional example 2 shown in FIG. The lever 124 has a handle 124b and is operated from the side (front side) of the lower die set plate 102. That is, the handle 124 b of the lever 124 is turned by hand, the cam portion 124 a is rotated around the central axis of the lever, and the material positioning pin 121 is projected on the die plate 106 via the knock pin 123. Thereafter, the workpiece 1 inserted into the guide groove 110d of the guide pin 110a is brought into contact with the material positioning pin 121 to set the workpiece 1. After the setting, when the hand is released from the handle 124b, the lever 124 is rotated by its own weight, so that the material positioning pin 121 is lowered by its own weight and retracted into the die plate 106.
[0007]
[Problems to be solved by the invention]
However, the above-described conventional material setting apparatus has the following problems.
(1) In the conventional example 1, since the material positioning pin 121 is urged in the protruding direction by the spring 122, an operation of inserting a bar or the like into the mold and pushing down the material positioning pin 121 is required. However, this operation is not only dangerous, but in the case of a small mold, the gap becomes small, and the setting work becomes difficult.
(2) In Conventional Example 2, the lever 124 may be tight and may not rotate under its own weight. If this happens, the material positioning pin 121 will not be lowered, and if the mold is operated as it is, the mold may be destroyed. Further, since it is a cam type, it is necessary to make the lever 124 thick, which hinders downsizing of the mold.

[0037]
In the present invention, the material guide lifter device is not particularly limited. As shown in the conventional example, the present invention can also be applied to the material guide lifter device 110 composed of a plurality of freely accessible pins. However, in order to facilitate the insertion and feeding of the workpiece 1, the material guide lifter device 30 is configured as follows in the present invention.
[0038]
The material guide lifter device 30 is fixed on the die plate 12 of the lower mold 10 with screws (not shown), and a pair of guide members 31 that guide the feed of the workpiece 1 and between each guide member 31. A guide passage 33 for the workpiece 1 is formed, and a plurality of block-like lifter members 32 are provided so as to freely enter and leave the die plate 12. The gap of the guide passage 33 is designed to be slightly larger than the thickness of the workpiece 1.
[0039]
The guide member 31 is made of an L-shaped member, and is mounted on the die plate 12 with the horizontal portion 31a facing upward and facing each other inward. The guide members 31 are attached so that the inner width of the guide members 31 is slightly larger than the width of the workpiece 1. Accordingly, the side edge portion of the workpiece 1 is guided to feed along the inner surface of the vertical portion 31b of the guide member 31, and the horizontal portion 31a prevents the workpiece 1 from being lifted.
In addition, an inclined portion 31c is formed in the horizontal portion 31a at the entrance end of each guide member 31 so that the workpiece 1 can be easily inserted.
[0040]
The lifter member 32 is composed of a plate-like block member that is formed long in the feed direction of the workpiece 1. These block members are arranged in series, and the side edge of the workpiece 1 is arranged on the upper surface. To support. And the protrusion height of each lifter member 32 is always controlled so that the clearance gap between the lifter member 32 and the horizontal part 31a of the guide member 31 becomes the guide channel | path 33 of the side edge part of the workpiece 1 always. . Thereby, the height level of the upper surface (workpiece support surface) of each lifter member 32 is parallel to the upper surface of the die plate 12 and is horizontal.
[0041]
The lifter members 32 are alternately arranged at both side edges of the workpiece 1. That is, the lifter members 32 are arranged so that the gaps 34 between the adjacent lifter members 32 are alternated in one row and the other row. Therefore, the tip of the workpiece 1 does not exist in the gap 34 at the same time, and one of the side edges always extends on the front and rear lifter members 32 across the gap 34. Further, in order to keep the size of the gap 34 constant, a plurality of types of lifter members 32 having different sizes (lengths) are used. Accordingly, the positions of the gaps 34 on both sides are alternated, and the positions of the material inlet end and the outlet end of the lifter members 34 on both sides can be matched.
[0042]
An inclined portion 32a is provided at the tip end of the lifter member 32 on the workpiece insertion side, and the lower end of the inclined portion 32a is designed to substantially coincide with the upper surface of the die plate 12 when lifted.
The lifter member 32 is urged in the protruding direction by a spring 35. The spring 35 is inserted through a hole 36 provided in the lower die set plate 11 and is mounted between the upper lifter member 32 and the lower set screw 38. One or more springs 35 are arranged in a well-balanced manner so that the lift force acts on the lifter member 32 evenly.
[0043]
The lifter member 32 is inserted into the die plate 12 into, for example, an opening 37 formed by electric discharge machining. In order to restrict the protruding height of the lifter member 32, the opening 37 is provided with stepped portions 37b formed by a wide lower opening 37a, and these stepped portions 37b are provided at the lower end of the lifter member 32. The step portions 32b are brought into contact with each other to be locked. This locking means may be a method using a long hole and a pin, for example, but the contact method between the step 37b in the opening 37 and the step 32b at the lower end of the lifter member 32 is easier. Thus, it is easy to mount the lifter member. Further, the step portions 37b and 32b may be provided only in one of the plate thickness directions, or may be a flange portion projecting all around like a flange.
[0044]
Setting of the workpiece 1 using the material setting device 40 and the material guide lifter device 30 is performed as follows.
When the operator pushes the lever 42 by hand or using a bar or the like, the inclined portion 42a at the tip of the rod portion 42b enters under the lower end portion 41b of the material positioning pin 41, and the lower end portion 41b enters the inclined surface of the inclined portion 42a. Lift along. As a result, the material positioning pins 41 protrude from the die plate 12 as indicated by broken lines in FIG. In this state, the workpiece 1 is inserted into the gap formed by the guide member 31 and the lifter member 32 of the material guide lifter device 30, that is, the guide passage 33, and the material positioning in which the tip of the workpiece 1 is protruded as described above. It abuts on the pin 41. Here, the setting of the workpiece 1 in the first step of press working, that is, the setting of the blank material is performed. Next, the hand or the bar is released from the lever 42 and the lever 42 is returned to the original position by the spring 43. When the lever 42 returns, the inclined portion 42a moves backward, so that the material positioning pin 41 is lowered by its own weight, and the upper end 41a is retracted into the die plate 12. Therefore, at this time, the first step is pressed.
[0045]
According to the configuration of the material setting device 40, since the material positioning pin 41 protrudes or retracts from the upper surface of the die plate 12 when the operator pushes or releases the lever 42 with a hand or a rod or the like, the setting operation is performed. Can be performed safely and easily. In addition, since a rod or the like is not inserted into the mold, there is no problem even if the mold is downsized. Further, since the material positioning pins 41 are retracted from the upper surface of the die plate 12 in the second and subsequent steps of press working, the workpiece 1 can be easily fed forward. Even if the material positioning pin 41 is not lowered due to its own weight and is caught in the middle, it is pushed down by the lowering of the upper mold 20, so there is no possibility of destroying the mold.
Furthermore, by using this material guide lifter device 30, the lifter member 32 is formed in a block shape, so that the workpiece 1 can be inserted and fed smoothly and quickly.
[0046]
The operation of the material guide lifter device 30 will be described as follows. The workpiece 1 is inserted in the direction of the arrow shown in the figure. Each lifter member 32 protrudes at a predetermined height above the die plate 12 by a spring 35, and forms a guide passage 33 extending horizontally with the horizontal portion 31 a of each guide member 31. The tip of the workpiece 1 is inserted from the entrance of the guide passage 33 to the position of the processing portion in the first step. When the press process in the first process is completed, the process is sequentially fed to the position of the processed part in the next second process. In this way, the processing part is sequentially fed to the position of the processing part in the final process, and when the pressing process is completed, the tip of the workpiece 1 comes out from the outlet of the guide passage 33, and then automatic pressing is started. Further, at each press working, the lifter member 32 is pushed down against the force of the spring 35 by the stripper plate 23 of the upper die 20 through the work material 1, and the work material 1 is pressed against the upper surface of the die plate 12. In a state, a predetermined pressing process is performed by a punch or a bending die. When each press process is completed, the lifter member 32 protrudes to the original position by the spring 35, thereby lifting the workpiece 1 above the die plate 12. Then, the workpiece 1 is sequentially fed to the next processing portion position.
[0047]
In the material guide lifter device 30, the lifter member 32 is formed in a block shape that is long in the feed direction of the workpiece 1, and the lifter members 32 on both sides are alternately arranged. The tip always rests on one of the lifter members 32. In addition, since the inclined portion 32a is provided at the distal end portion of the lifter member 32 on the workpiece insertion side, even if the distal end of the workpiece 1 hangs down due to its own weight, the inclined portion 32a smoothly puts on the lifter member 32. It will be lifted. Therefore, according to the configuration of the material guide lifter device 30, the workpiece 1 can be inserted very easily and can be inserted very smoothly without hitting anywhere. Therefore, extremely safe and quick insertion is possible.
[0048]
