Description

TECHNICAL FIELD

[0001] The application relates to the technical field of plate stamping, in particular to a metal plate stamping die. BACKGROUND

[0002] Plate stamping refers to a plate forming processing method that metal plates are subjected to external force through stamping equipment and a die so that the metal plates are deformed or separated, thereby obtaining workpieces with required shapes and sizes. Currently, most of the metal plate stamping dies on the market adopt fixed punch design, that is, the punch is fixedly connected with the upper die seat, and cannot be flexibly adjusted according to the specific shape on the plate or the position that needs to be avoided. However, in the actual use process, due to the differences in the shape, size and structure of the plate, especially when the plate containing holes, flanges or protrusions is processed, the die needs to be frequently replaced, which increases the production time and cost and reduces the production efficiency.

[0006] Preferably, the lower die seat comprises a mounting plate, a guide column is arranged on the mounting plate, the upper end of the guide column penetrates through the upper die seat and is connected with the upper die seat in a sliding mode.

[0007] Preferably, a lower concave die is arranged on the mounting plate, and the lower concave die is used in cooperation with the adjustable punch.

[0008] Preferably, a plurality of guide grooves are arranged on the punch seat, the movable cutter die comprises a punch slidingly arranged in the punch seat, a plurality of positioning blocks are arranged on the side surface of the punch, and the positioning blocks are slidingly arranged in the corresponding guide grooves.

[0009] Preferably, the distal end of the positioning block is connected with the clamping plate.

[0010] In summary, the present application includes the following beneficial technical effects:

[0011] By combining the punch, positioning assembly, and lower die, the positioning assembly on the movable die without stamping operation can be removed as needed, the locking of the movable die by the clamping plate and magnetic column is released, and the movable die can move up and down along the movable die. During stamping, the movable die not limited by the clamping plate and magnetic column slides relative to the punch holder after contacting the metal plate, and the movable die limited by the clamping plate and magnetic column does not slide relative to the punch holder after contacting the metal plate, and still performs stamping operation. Compared with the prior art, the present application has the effects of convenient operation and strong applicability. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0016] The following will be described in detail in combination with the accompanying Figures 1-3 The present application will be further described in detail.

[0017] The embodiment of the present application discloses a metal plate stamping die. Referring to Figures 1-3 A metal plate stamping die, comprising a lower die seat 1 and an upper die seat 2, wherein the upper die seat 2 is installed on the movable end of the hydraulic cylinder of the plate stamping and bending machine through bolts, the lower die seat 1 comprises a mounting plate 101 with mounting holes, the mounting plate 101 is fixed on the workbench of the plate stamping and bending machine through bolts passing through the mounting holes, and a plurality of guide columns 102 are installed on the mounting plate 101, the upper die seat 2 is sleeved on the plurality of guide columns 102, and the guide columns 102 guide the stamping of the upper die seat 2 to ensure the precision of stamping.

[0018] Referring to Figure 2The lower end of the upper die holder 2 is detachably connected with a combined die 3, the combined die 3 comprises a punch holder 301 mounted on the upper die holder 2 by bolts, a knife groove is mounted in the middle of the punch holder 301, an adjustable punch is slidably mounted in the guide groove, the adjustable punch is composed of a plurality of independent movable knives 302, the movable knife 302 comprises a punch 3021 slidably mounted in the knife groove, two guide grooves are formed on both sides of each punch 3021 on the punch holder 301, a positioning block 3022 is slidably mounted in the guide groove, the positioning block 3022 is fixedly connected with the punch 3021, the punch 3021 is guided by the positioning block 3022 to slide up and down in the knife groove, and stamping avoidance is realized.

[0019] Referring to Figure 3 , the inner side of the two positioning blocks 3022 on the punch 3021 is provided with a through hole, a clamping groove 6 is mounted between the two guide grooves on the punch holder 301, a positioning assembly 4 is mounted in the clamping groove 6, the positioning assembly 4 comprises a positioning column slidably mounted in the through hole, and the end portions of the two positioning columns are in close contact with each other, the positioning column adopts two magnetic columns 402 with opposite magnetic poles, the two magnetic columns 402 are attracted by the magnetic force of the magnetic column 402, so that the two magnetic columns 402 form an integral whole, which is not easy to fall off, and facilitates subsequent disassembly, one end of the two magnetic columns 402 away from each other penetrates through the punch holder 301 and is connected with a clamping plate 401, the clamping plate 401 is slidably mounted in the clamping groove 6, the clamping plate 401 is clamped above the positioning block 3022, the positioning block 3022 is clamped and positioned by the clamping plate 401, the punch 3021 is positioned to prevent it from sliding, a pull ring 403 is mounted on the clamping plate 401, which facilitates subsequent separation of the magnetic columns 402, and quick disassembly is realized.

[0020] Referring to Figure 1 , the mounting plate 101 is provided with a lower concave die 5, the lower concave die 5 is used in combination with the punch 3021, and can be customized according to the bending angle of the plate.

[0021] The implementation principle of the metal plate stamping die in the embodiment of the application is as follows:

[0022] When there is a part on the plate that does not need to be stamped, the magnetic columns 402 can be separated by pulling the pull ring 403, so that the clamping plate 401 is quickly disassembled, and the positioning of the positioning block 3022 by the clamping plate 401 is released.

[0023] When the plate is placed on the lower concave die 5, the hydraulic cylinder of the plate stamping and bending machine starts to work, and pushes the upper die holder 2 to move downward. The upper die holder 2 drives the combined die 3 to move downward, and the punch 3021 cooperates with the lower concave die 5 to stamp the plate. Due to the guidance of the guide column 102, the precision and stability of the stamping are ensured.

[0024] In the stamping process, if the punch 3021 encounters a position that needs to be avoided (such as a hole, a flange or a protrusion on the plate), the punch 3021 can slide up and down in the tool groove, and the avoidance is realized through the guiding action of the positioning block 3022, so as to avoid damaging the mold or the plate.
