The pressing vertical surface 248 faces the corresponding vertical surface 224 of the material support frame 22 and is spaced apart from the corresponding vertical surface to press the corresponding vertical plate 12 of the workpiece 1. The pressing vertical surface 248 can cooperate with the corresponding vertical surface 224 to clamp the corresponding vertical side plate 12. The second blade edge 249 is located at the bottom end of the abutment face 248 and has a height in the longitudinal direction Z slightly higher than the height of the first blade edge 240 of the punch 232. Thereby, the first blade edge 240 can be tangent to the second blade edge 249 to generate a shearing force to cut off the corresponding side panel 12. Two shoulder surfaces 250 are located on the front and rear sides of the pressing block 243, and each shoulder surface 250 is stopped by the stopper rib portion 217 of the corresponding guide plate 213. The stop rib 217 of each guide plate 213 stops the corresponding shoulder surfaces 247, 250, thereby preventing the second sliding member 24 from moving upward and away from the first sliding plate 230. The pressing block 243 is formed with an accommodating groove 251 facing the corresponding accommodating groove 225 of the material receiving frame 22 for accommodating a portion of the punch 232.

The inclined surface 373 contacts and pushes the second inclined surface 245 of the second protrusion 242, and the inclined surface 374 contacts and pushes the first inclined surface 237 of the first protrusion 231.

The following describes a mode of the side-punching die 200 for performing the side-punching trimming process on the workpiece 1:

referring to fig. 3, first, the workpiece 1 is placed on the carrier body 222 of the carrier 22, such that the carrier top surface 223 carries the flat plate 11 of the workpiece 1, and each of the side vertical plates 12 abuts against the corresponding side vertical surface 224. Each side vertical plate 12 protrudes out of the bottom end of the corresponding side vertical surface 224 by a certain distance. The first bolt 261 is elastically urged by the first spring 262 of each first reset group 26 such that the corresponding first sliding group 23 is maintained at the initial position shown in fig. 3. The second bolt 271 is elastically urged by the second spring 273 of each second reset group 27 through the washer 272 such that the corresponding second slide group 24 is maintained at the initial position shown in fig. 3.

Referring to fig. 7, the upper die 3 is driven by the punch to move downwards along the longitudinal direction Z, and the upper stripper plate 35 will press the top surface of the flat plate 11 of the workpiece 1 and clamp the flat plate 11 together with the bearing top surface 223 during the downward movement of the upper die 3, so as to prevent the flat plate 11 from shaking up and down. Meanwhile, the top of the second protrusion 242 and the top of the pressing block 243 of each second sliding set 24 are accommodated in the corresponding groove 351.

Referring to fig. 8, during the downward movement of the upper mold 3, since the upper stripper plate 35 presses the flat plate 11 of the workpiece 1 and is stopped by the material holder 22, the upper stripper plate 35 and the upper stripper plate 34 do not move downward, and only the upper mold base 31, the upper backing plate 32, the upper clamping plate 33, the spring 36 and the wedge 37 move downward. During the downward movement of the above-mentioned components, the spring 36 is pressed and deformed by the upper cushion plate 32, and the inclined surface 373 of the wedge body 371 of each wedge 37 contacts the second inclined surface 245 of the corresponding second protrusion 242, and the lateral component force applied to the second inclined surface 245 by the wedge body 371 pushes the second sliding set 24 to slide along the first sliding direction D1 parallel to the horizontal direction Y. In the process that the second sliding group 24 slides along the first sliding direction D1, the abutting vertical surface 248 of the abutting block 243 approaches the corresponding side vertical plate 12, and the second sliding plate 241 drives the second bolt 271 to move along the first sliding direction D1. The second spring 273 is compressed and deformed by the bolt head and the washer 272 during the movement of the second bolt 271 and accumulates the restoring elastic force.

Referring to fig. 9 and 10, when the wedge body 371 continues to move downward to separate the inclined surface 373 from the second inclined surface 245, and the wedge body 371 contacts the upright surface 246 of the second protrusion 242 with the upright surface 375 connected to the top end of the inclined surface 373, the second sliding set 24 cannot continue to slide along the first sliding direction D1. At this time, the second sliding group 24 is positioned at the pressing position as shown in fig. 9. When the second sliding group 24 is at the pressing position, the pressing vertical surface 248 of the pressing block 243 presses the corresponding side vertical plate 12 and clamps the corresponding side vertical plate 12 together with the corresponding side vertical surface 224, thereby preventing the side vertical plate 12 from shaking left and right.

Referring to fig. 11 and 12, as each wedge 37 of the upper mold 3 continues to move downward, the inclined surface 374 of the wedge body 371 contacts the first inclined surface 237 corresponding to the first protrusion 231, and the lateral component of the force applied to the first inclined surface 237 by the wedge body 371 pushes the first sliding set 23 to slide along a second sliding direction D2 parallel to the horizontal direction Y and opposite to the first sliding direction D1. During the sliding of the first sliding group 23 in the second sliding direction D2, the first protrusion 231 presses the second spring 273 to continue the compression deformation, and the first sliding plate 230 presses the first spring 262 to compress the deformation and accumulate the return elastic force through the first bolt 261. The first blade 240 of the punch 232 protrudes out of the accommodating groove 225 and moves towards the second blade 249 of the pressing block 243, the first blade 240 presses the corresponding side plate 12 to deform the corresponding side plate, and then the shearing force generated by the first blade 240 passing below and tangent to the second blade 249 gradually breaks the corresponding side plate 12.

When the upper clamping plate 33 of the upper die 3 contacts and is blocked by the upper stripper plate 34 from further downward movement, the first sliding group 23 is positioned in the punching position as shown in fig. 11. At this time, the first cutting edge 240 of the punch 232 is accommodated in the accommodating groove 251, and the shearing force generated by the tangency of the first cutting edge 240 and the second cutting edge 249 cuts the corresponding side plate 12 into the plate body 121 and the scrap 122, so as to complete the edge cutting process of the side plate 12.

Referring to fig. 3 and 11, the punch press drives the upper mold 3 to move upward and return to the initial position shown in fig. 3. At this time, the restoring elastic force required to be accumulated by the first spring 262 drives the first sliding group 23 to slide along the first sliding direction D1 (shown in fig. 8) through the first bolt 261 and restore to the initial position shown in fig. 3, and the restoring elastic force required to be accumulated by the second spring 273 drives the second sliding group 24 to slide along the second sliding direction D2 through the washer 272 and the second bolt 271 and restore to the initial position shown in fig. 3.

By means of the design manner that the wedge block 37 firstly pushes the second sliding group 24 to slide to the abutting position and then pushes the first sliding group 23 to slide to the punching position, the abutting vertical surface 248 and the corresponding side vertical surface 224 of the abutting block 243 can firstly clamp the opposite side vertical plate 12 of the workpiece 1 to prevent the opposite side vertical plate 12 from swinging left and right, so that when the first cutting edge 240 of the punch 232 is matched with the second cutting edge 249 of the abutting block 243 to perform side punching on the side vertical plate 12, the side vertical plate 12 can be trimmed quickly and accurately, and the cut trace of the trimmed plate body 121 is smooth and beautiful, so that the plate body 121 meets the size requirement on subsequent assembly.

Referring to fig. 13, in another embodiment of the present invention, the number of the receiving groove 225, the first sliding group 23, the second sliding group 24, the first resetting group 26, the second resetting group 27, the groove 351 of the upper stripper plate 35, and the wedge 37 of the material-receiving frame 22 may be one, and the number is not limited to the number disclosed in the present embodiment.

In summary, in the side stamping die 200 of the present embodiment, the height of the portion of the second sliding set 24 for pushing the wedge 37 along the longitudinal direction Z is higher than the height of the portion of the first sliding set 23 for pushing the wedge 37, so that the wedge 37 can push the second sliding set 24 to slide to the pressing position first and then push the first sliding set 23 to slide to the stamping position. Borrow this, can cut edge and make the plate body 121 cut mark after cutting edge to the side riser 12 of work piece 1 fast and accurately level pleasing to the eye to make plate body 121 accord with the size demand on the follow-up equipment, can reach really the utility model discloses the purpose of claiming.
