[0020] In the above structure, the side punching blade, the side punching punch and the side punching driving mechanism are installed on the upper die, and a waste through hole is formed on the lower die seat of the lower die, which simplifies the structure of the stamping die for side punching. Compared with the side punching mechanism of the existing stamping die, the structure is simple and convenient for side punching of the product. More importantly, a blanking blocker is installed on the upper die. When the stamping die is closed, the blanking blocker can open the blanking hole of the side punching blade, and the waste generated by the side punching can fall through the blanking hole and the waste through hole in sequence; when the stamping die is opened, the blanking blocker can close the blanking hole of the side punching blade, and the waste is blocked and sealed in the blanking hole. In this way, the problem that the waste of the existing stamping die often falls disorderly on the lower die surface, resulting in the inability to produce smoothly is solved. It can be better applied to the side punching process in which the waste falls from the stripping plate of the upper die, thereby expanding the use conditions of this punching process.

[0021] Preferably, the side punch driving mechanism includes a side punch slider 1531, a side punch insert block 1532, a side punch stop block 1533, a side punch connecting rod 1534 and a side punch return spring 1535, the side punch slider is horizontally slidably installed at the bottom of the stripping plate, the side punch head is installed at the front end of the side punch slider, and the rear end of the side punch slider is formed with a first driving inclined surface 15311; the top end of the side punch insert block is installed in the upper clamping plate, and the bottom end of the side punch insert block is formed with a second driving inclined surface facing the side punch slider. Surface 15321, a block avoidance hole 141 for avoiding the side punch block is formed on the stripping plate; the side punch stop block is installed at the bottom of the stripping plate, and the front side wall of the side punch stop block is flush with the block avoidance hole, and a flange 15341 is formed at the rear end of the side punch connecting rod, and the front end of the side punch connecting rod moves through the connecting rod avoidance hole on the side punch stop block and is fixedly connected to the rear end of the side punch slider, and the side punch reset spring is positioned between the rear side wall of the side punch stop block and the flange. In this way, when the stamping die is closed, the upper clamping plate and the stripping plate are closed, and the side punch block can move downward through the mutual cooperation between the first driving inclined surface and the second driving inclined surface, driving the side punch slider to slide horizontally, thereby driving the side punch head fixed on the side punch slider to slide horizontally, so as to perform side punching on the product positioned on the side punch blade. At the same time, during the movement of the side punch slider toward the side punch blade, the side punch slider will pull the side punch connecting rod, thereby compressing the side punch reset spring to store energy, and the side punch stop block is installed at the bottom of the stripping plate and is flush with the blanking hole, thereby guiding and stopping the side punch block to move downward. When the stamping die is opened, the upper die seat, the upper pad and the upper clamping plate move upward, the upper clamping plate and the stripping plate open, and drive the side punch block to reset. At the same time, the energy stored in the side punch reset spring is released, and the reset side punch slider drives the side punch head to reset, completing a side punching, and then reciprocating. Among them, the structure in which the side punch slider is horizontally slidably installed at the bottom of the stripping plate can be in the form of a dovetail guide groove and a dovetail tenon.

[0022] Preferably, the side punch stop block is L-shaped, the top of the vertical part of the side punch stop block is installed at the bottom of the stripper plate, the front side wall of the vertical part of the side punch stop block is flush with the plug block avoidance hole, and the transverse part of the side punch stop block faces the side punch slider. In this way, the side punch stop block is designed to be L-shaped, the vertical part of the side punch stop block can guide and stop the side punch plug block, and the transverse part of the side punch stop block can limit the maximum stroke of the side punch plug block, and can also stop and position the side punch slider, and the connecting rod avoidance hole is designed in the transverse part to guide the side punch connecting rod.

[0023] Preferably, the side punch driving mechanism further includes a side punch discharge spring 1536, a side punch discharge plate 1537 and a punch fixing plate 1538, wherein the side punch is installed at the front end of the side punch slider through the punch fixing plate, the side punch discharge plate is horizontally slidably installed at the bottom of the stripping plate, and a punch avoidance hole for avoiding the side punch is formed on the side punch discharge plate, and the side punch discharge spring is installed between the punch fixing plate and the side punch discharge plate. In this way, the side punch can be installed at the front end of the side punch slider through the punch fixing plate, and the side punch discharge plate is elastically driven by the side punch discharge spring, so that the side punch can be quickly separated from the product after the side punch hole, thereby playing a role of discharge.

[0024] Preferably, the product is L-shaped, the vertical part of the product is positioned on the side punch blade, and the transverse part of the product is located at the bottom of the side punch discharge plate. The side punch head is installed on the upper die, and the transverse part of the L-shaped product is convenient to extend at the bottom of the side punch head, which is convenient for product positioning.

[0025] Preferably, a first slope surface 1522 is formed on the front side of the bottom end of the side punch blade, the blanking blocker is L-shaped, the top of the vertical part of the blanking blocker passes through the stripper plate and is installed on the upper clamping plate, the transverse part of the blanking blocker is located below the side punch blade, and can be accommodated in the waste material through hole, and can close the blanking hole, and the top of the transverse part of the blanking blocker is formed with a second slope surface 161 matching the first slope surface. In this way, the blanking blocker is designed to be L-shaped, the vertical part of the blanking blocker is better installed on the upper mold, and the transverse part of the blanking blocker can better achieve the function of closing the blanking hole. And through the cooperation between the first slope surface and the second slope surface, the slope surface can also guide the discharge of the waste material, which is convenient for the discharge of the waste material.

[0026] Preferably, the punching opening 1523 of the side punching edge is composed of a straight opening portion 15231 and a flared opening portion 15232, and the flared opening portion is connected between the straight opening portion and the blanking hole. Here, the punching opening corresponds to the side punching head and is used to cut waste materials. The punching opening is designed to have a straight opening portion and a flared opening portion, and the flared opening portion is connected, which can facilitate the falling of waste materials and avoid the waste materials from being stacked together, resulting in the side punching edge being damaged by explosion.

[0027] Preferably, a stripping spring is installed between the stripping plate and the upper clamping plate, and the stripping spring elastically separates the stripping plate and the upper clamping plate by a certain distance. Usually, one end of the stripping spring is installed on the upper die seat of the upper die, and the other end passes through the upper pad and the upper clamping plate to connect with the stripping plate, so as to realize the function of popping open the stripping plate.

[0028] The working principle of the waste material falling control mechanism of the punching die side of the present invention is as follows:

[0029] In the initial state, the upper die and the lower die are in an open state, the upper clamp and the stripper plate are in an open state, and the front end of the side punch is retracted into the punch avoidance hole of the side punch stripper plate. The second slope surface at the top of the transverse part of the blanking blocker fits with the first slope surface at the bottom of the side punch blade, and the transverse part of the blanking blocker closes the blanking hole, and the waste is blocked and closed in the blanking hole. At this time, the product to be punched is positioned and placed on the side punch blade.

[0030] When closing the mold, the upper mold and the lower mold are first closed, and the blanking blocker and the side punch blade are partially accommodated in the waste through hole on the lower mold base. Then, the upper mold continues to move downward, the upper clamping plate and the stripper plate are closed, and the side punch plug block passes through the plug block avoidance hole on the stripper plate. Through the interaction between the first driving inclined surface and the second driving inclined surface, the side punch slider is driven to move toward the side punch blade. At this time, the side punch head installed at the front end of the side punch slider begins to side punch the product. While the side punch slider moves toward the side punch blade, the side punch slider will pull the side punch connecting rod, thereby compressing the side punch reset spring to store energy. While the side punch head moves toward the side punch blade, the side punch stripper plate will compress the side punch stripper spring to store energy.

[0031] When opening the mold, the upper mold base, upper pad and upper clamping plate move upward, the upper clamping plate and stripping plate open first, and the upper clamping plate drives the side punch block to move upward and reset. At the same time, the side punch reset spring stores energy and releases it, and the reset side punch slider drives the side punch head to reset. At the same time, the unloading spring stores energy and releases it, and the side punch unloading plate is reset to separate the side punch head from the product, completing a side punching hole, and then repeating the cycle.

[0032] Therefore, the present invention solves the problem that waste materials of existing stamping dies often fall disorderly on the lower die surface, thus causing unsmooth production. It can be well applied to the side punching process where waste materials fall from the stripping plate of the upper die, thereby expanding the use conditions of this punching process.
