[0002] In the field of processing drawer guide hanging plates, traditional stamping processing methods have many limitations. In the early stage, manual feeding was mostly relied on, which not only had low efficiency, but also the feeding accuracy was greatly affected by human factors, resulting in uneven product quality and a high rejection rate. At the same time, it was difficult to achieve continuous and stable stamping operations with manual feeding, seriously restricting the improvement of production efficiency.

[0003] In terms of stamping dies, the traditional die structures are often fixed and single, and it is difficult to meet the processing requirements of various specifications of drawer guide hanging plates. When it is necessary to produce hanging plates of different sizes or shapes, usually the whole set of dies needs to be replaced, which is time-consuming, laborious and costly. Moreover, during the stamping process of traditional dies, the buffering and control of the impact force at the moment of stamping are insufficient, which easily causes rapid wear of the dies and damage to the equipment, further increasing the production cost and maintenance workload.

[0018] 1. The automatic feeding unit is firmly connected to the left side of the lower die base of the stamping die unit through bolts. The feeding groove on the top of the feeding frame provides a placement and conveying channel for the raw materials. The servo cylinders one on the front and rear sides of the feeding frame can flexibly drive the positioning frame to move up and down according to the thickness of the raw materials, accurately adjusting the distance between the positioning frame and the feeding groove to ensure that raw materials of different thicknesses can be effectively positioned and conveyed. The feeding rollers with rubber rings in the middle of the feeding groove and the positioning frame rotate clockwise below and counterclockwise above, clamping and conveying the raw materials in opposite directions to enhance the feeding stability. The servo cylinders two on the front and rear sides in the feeding groove push the limiting frame to move, and its guiding conveyor belt guides and limits the raw materials to prevent deviation. At the same time, the built-in motor that controls the rotation of the feeding rollers is connected to the rotation shaft stroke recorder, which accurately records the rotation stroke and precisely controls the feeding accuracy, greatly improving the processing efficiency and quality and reducing manual intervention.

[0019] 2. In the stamping die unit, the lower template is fixed at the top of the lower die base, and the guiding columns around are slidably connected with the guiding sleeves in the upper die base, ensuring the precise and stable up-and-down movement of the upper die base and providing reliable guidance for stamping. The stamping plate moves under the upper template through the positioning slide bars, and the positioning slide bars are slidably connected with the upper die base and the upper template. Cooperating with the buffer springs, it can effectively buffer the impact force during stamping, reduce the damage to the die and equipment, extend the service life, and can also meet the stamping requirements of materials with different thicknesses, improving the stamping quality.

[0020] 3. The connection slider one in the chute one connected to the left side of the bottom of the upper template drives the stamping rod to move, which cooperates with the connection slider two in the chute two in the stamping plate and the adjusting punching block in the adjusting groove in the lower template, and can flexibly adjust the punching position and spacing to achieve multi-group hole stamping processing at one time. With the shape of the punching hole being smaller at the top and larger at the bottom and the inclined surface design of the discharge chute, it is convenient for the waste to be discharged and avoids accumulation affecting the quality. In the stamping forming groove on the right side of the lower template, the servo electric cylinder three drives the forming adjusting plate to slide, flexibly adjusting the stamping forming space. The movable telescopic column in the telescopic groove expands and contracts according to the stamping situation under the action of the fixed rod and the connection spring, playing a role of buffering and supporting. The adjustable stamping block on the right side of the bottom of the upper template and the telescopic adjusting block on its left side are driven by the electric sliding table and can flexibly change the stamping shape to meet the stamping forming requirements of hanging plates with different shape specifications. The servo linear slide table in the groove on the right side of the bottom of the stamping plate drives the stamping cutter to slide, and the protruding length of the bottom end of the stamping cutter can be adjusted by the bolt group according to the thickness of the raw material to achieve precise cutting, making the entire stamping process more flexible, efficient and precise, and greatly improving the production diversity and product quality.

[0047] Embodiment 2

[0048] Specifically, the working method of the continuous stamping mechanism for processing drawer guide hanging plates is also disclosed in this embodiment, and the specific process is as follows:

[0049] Feeding preparation stage: Place the raw material of the drawer guide hanging plate on the feeding chute 14 at the top of the feeding rack 13 of the automatic feeding unit 2. According to the raw material thickness, start the servo cylinder one 15 on the front and rear sides of the feeding rack 13 to drive the positioning rack 16 to move up and down, adjust the distance between the positioning rack 16 and the feeding chute 14, and stably clamp the raw material; turn on the feeding rollers 17 in the middle of the feeding chute 14 and the positioning rack 16. Since the lower feeding roller 17 rotates clockwise, the upper feeding roller 17 rotates counterclockwise, and the rubber rings on the surface of the feeding rollers 17 increase the friction with the raw material, effectively clamping and conveying the raw material. At the same time, the rotation stroke recorder connected to the rotating shaft of the built-in motor for controlling the rotation of the feeding roller 17 starts to work, accurately recording the rotation stroke of the feeding roller 17 to ensure the feeding accuracy; the servo cylinder two 20 on the front and rear sides inside the feeding chute 14 pushes the limiting rack 18 to move, so that the guiding conveyor belt 19 on the limiting rack 18 plays a guiding and limiting role for the raw material, ensuring that the raw material will not shift during the feeding process and further improving the feeding accuracy.

[0050] Punching processing stage: When the raw material is conveyed to the stamping area of the stamping die unit 1, start the stamping control unit 3. The punching rod 25 passes through the connecting slider two 24 in the connecting chute two 23 in the stamping plate 8 and cooperates with the adjusting punching block 27 in the adjusting groove 26 in the lower template 7. By adjusting the positions of the connecting slider one 22, the connecting slider two 24 and the adjusting punching block 27, the punching processing of different positions on the raw material can be flexibly realized. Multiple groups of punching rods 25 and adjusting punching blocks 27 work together to realize the punching processing of multiple groups of holes on the raw material at one time;

[0051] During the stamping process, for the waste generated, due to the shape design of the internal matching punching hole 28 in the punching block 27 being smaller at the top and larger at the bottom, and the structure design of the bottom of the inner wall of the discharge chute 29 having an inclined surface and one side extending to the front of the lower die base 5 with a lower front and higher rear, the waste can smoothly pass through the matching punching hole 28 and fall into the discharge chute 29, and be discharged from the lower die base 5 along the discharge chute 29, avoiding waste accumulation and affecting the stamping quality;

[0052] Stamping forming stage: The raw material after punching is continuously conveyed to the position of the stamping forming groove 30 on the right side of the lower template 7.
