Description

Technical Field

[0001] This utility model belongs to the field of stamping die support technology, and in particular relates to a material support with positioning and sensing functions in a multi-station stamping die. Background Technology

[0002] Traditional material supports only include material positioning and material arrival sensing functions. However, when there is a height difference on the blank holder surface of the drawing die, an additional floating material support must be added inside the die. This not only increases the die cost but also reduces die stability. Our invention proposes a material support with positioning and sensing functions for multi-station stamping dies. It integrates material support, material positioning, and material arrival sensing functions into one unit, which can save die space, reduce die cost, and facilitate die debugging. Utility Model Content

[0003] The purpose of this utility model is to provide a material support with positioning and sensing functions in a multi-station stamping die, which aims to solve the technical problem in the prior art that when there is a height difference on the blanking surface of the drawing die, an additional floating material support must be added to the die, which not only increases the cost of the die but also results in low die stability.

[0004] To achieve the above objectives, this utility model provides a material support with positioning and sensing functions within a multi-station stamping die, comprising an L-shaped positioning bracket, a lifting mechanism, a sensing swing block, and a sensor. The L-shaped positioning bracket includes a mounting portion and a connecting portion. One end of the mounting portion is connected to one end of the connecting portion. The mounting portion has a mounting groove, and a mounting hole is provided at the connection between the mounting portion and the connecting portion. The mounting hole passes through the L-shaped positioning bracket along its side end and communicates with the mounting groove. The mounting hole is used to mount the sensor. The sensing swing block is disposed within the mounting groove and is hinged to the mounting portion. The sensing swing block rotates around its hinge point with the mounting portion until its upper end extends out of the mounting groove towards the connecting portion, and its lower end extends out of the mounting groove away from the connecting portion. The lifting mechanism includes a lifting block and an elastic reset member. The lifting block is hinged to one side of the mounting part, and one side of the lifting block extends horizontally to the outside of the mounting part in the direction away from the connecting part. The extended end of the lifting block is lower than the end of the sensing swing block that extends out of the mounting through groove in the direction away from the connecting part. The elastic reset member is used to reset the extended end of the lifting block to keep it horizontal.

[0005] Furthermore, a waist-shaped hole is provided through the connecting part.

[0006] Furthermore, the inductive pendulum includes a counterweight and a sensing part, which are connected and located below the counterweight. One end of the counterweight extends towards the connecting part, while the other end extends obliquely downwards away from the connecting part. The sensing part rotates around the hinge point between the inductive pendulum and the mounting part, passing through a mounting hole.

[0007] Furthermore, the counterweight is provided with an arc-shaped limiting groove, and the lifting block is provided with a limiting screw. The limiting screw extends toward the counterweight and passes through the arc-shaped limiting groove to limit the counterweight.

[0008] Furthermore, the elastic reset component includes a reset spring, one end of which is connected to one side of the mounting portion, and the other end is connected to the lifting block.

[0009] The material support with positioning and sensing functions in a multi-station stamping die provided by this utility model embodiment has at least one of the following technical effects: When the material support with positioning and sensing functions in a multi-station stamping die provided by this utility model is installed on the lower die, the stamping material is placed on the pressure ring in its natural state, with the higher end of the profile resting on the pressure ring and the lower end resting on the lifting block. After the stamping material contacts the upper end of the sensing swing block, the stamping material drives the sensing swing block to rotate around its hinge point with the mounting part. Driven by the stamping material, the lower end of the sensing swing block swings to the sensing hole position, thus meeting the stamping requirements and reaching the working state. After the sensor recognizes the sensing swing block, it transmits a signal to the press. Only then can the upper table move the upper die base downwards to begin the stamping operation. After the upper die contacts the stamping material, because the driving force of the press is much greater than the pulling force of the elastic reset member, the stamping material begins to drive the lifting block to swing upwards, avoiding the stamping material, thus completing the stamping and drawing process. After drawing is complete, the upper table moves the upper die upwards, and the induction swing block loses its driving force from the stamping material, returning to its natural state under gravity. Similarly, the lifting block, losing the driving force from the stamping material and the press, also returns to its natural state under the pulling force of the elastic reset component. The pressure ring, under the action of a nitrogen spring or the press ejector rod, is lifted and reset. The robot arm then grips or picks up the product and places it in the next station. The material support has returned to its natural state from its working state, awaiting the next sheet feed. While satisfying the sensing function of the induction swing block, this system can also be applied in drawing stations with significant height differences. The supporting material makes the drawing process smoother, eliminates drawing defects caused by surface height differences, reduces workpiece manufacturing, reduces space occupation, reduces the processing costs of die mounting positions and clearances, and lowers the risk of interference from insufficient clearance in the processing of multiple positioning supports.

Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0018] In one embodiment of this utility model, reference is made to Figures 1-2As shown, a material support with positioning and sensing functions is provided in a multi-station stamping die, including an L-shaped positioning support 100, a lifting mechanism 200, a sensing swing block 300, and a sensor 400. The L-shaped positioning support includes a mounting part 110 and a connecting part 120. One end of the mounting part 110 is connected to one end of the connecting part 120. The mounting part 110 is provided with a mounting through groove 111. A mounting hole 112 is provided at the connection between the mounting part 110 and the connecting part 120. The mounting hole 112 passes through the L-shaped positioning support along the side end of the L-shaped positioning support and communicates with the mounting through groove 111. The mounting hole 112 is used to mount the sensor 400. The sensing swing block 300 is disposed in the mounting slot 111 and is hinged to the mounting part 110. The sensing swing block 300 rotates about its hinge point with the mounting part 110 until its upper end extends out of the mounting slot 111 in the direction close to the connecting part 120, and its lower end extends out of the mounting slot 111 in the direction away from the connecting part 120. The lifting mechanism 200 includes a lifting block 210 and an elastic reset member 220. The lifting block 210 is hinged to one side of the mounting part 110, and one side of the lifting block 210 extends horizontally to the outside of the mounting part 110 in the direction away from the connecting part 120. The extended end of the lifting block 210 is lower than the end of the sensing swing block 300 that extends out of the mounting slot 111 in the direction away from the connecting part 120. The elastic reset member 220 is used to reset the extended end of the lifting block 210 to keep it horizontal. In this embodiment, a material support with positioning and sensing functions, provided by this utility model, is installed on the lower die of a multi-station stamping mold. In its natural state, the stamping material is placed on the blank holder, with the higher end resting on the blank holder and the lower end resting on the lifting block 210. When the stamping material contacts the upper end of the sensing swing block 300, the stamping material drives the sensing swing block 300 to rotate around its hinge point with the mounting part 110. Driven by the stamping material, the lower end of the sensing swing block 300 swings to the sensing hole position, thus meeting the stamping requirements and reaching the working state. After the sensor 400 detects the sensing swing block 300, it transmits a signal to the press. Only then can the upper table move the upper die base downwards, starting the stamping operation. After the upper die contacts the stamping material, because the driving force of the press is much greater than the pulling force of the elastic reset member 220, the stamping material begins to drive the lifting block 210 to swing upwards. Avoiding the stamping material, the stamping and drawing process is completed. After the drawing is completed, the upper table moves the upper die upward, and the sensing swing block 300 will also lose the driving force of the stamping material and return to its natural state under the action of gravity. After the lifting block 210 loses the driving force of the stamping material and the press, it also returns to its natural state under the pulling force of the elastic reset component 220. The pressure ring is lifted and reset under the action of the nitrogen spring or the punch press push rod. The robot arm picks up or picks up the product and places it in the next workstation. The material support has returned from the working state to the natural state and is waiting for the next sheet to be fed.While meeting the sensing requirements of the 300-degree induction swing block, it can also be used in drawing stations with large height differences. The support material makes the drawing process smoother, eliminates drawing defects caused by surface height differences, reduces workpiece production, reduces space occupation, reduces the processing cost of mold installation positions and avoidance positions, and reduces the risk of interference due to insufficient processing avoidance of multiple positioning brackets.

[0019] Specifically, refer to Figures 1-2 As shown, the connecting part 120 is also provided with a through-hole 121. In this embodiment, the material support with positioning and sensing functions in the multi-station stamping die provided by the present invention is installed on the lower die by screws passing through the through-hole 121. The position of the L-shaped positioning support on the lower die can be easily and quickly adjusted through the through-hole 121, making assembly and adjustment more convenient.

[0020] Specifically, refer to Figures 1-2 As shown, the inductive pendulum 300 includes a counterweight 310 and a sensing part 320. The counterweight 310 is connected to the sensing part 320, and the sensing part 320 is located below the counterweight 310. One end of the counterweight 310 extends towards the connecting part 120, and the other end of the counterweight 310 extends obliquely from top to bottom away from the connecting part 120. The sensing part 320 rotates around the hinge point between the inductive pendulum 300 and the mounting part 110, passing through the mounting hole 112. In this embodiment, when the L-shaped positioning bracket 100 is not carrying the stamping material, due to the effect of the counterweight, the sensing part 320 is not on the side of the mounting hole 112, the sensor 400 cannot sense the sensing swing block 300, and the stamping machine will not start working. When the lifting block 210 carries the stamping material, the stamping material abuts against the sensing swing block 300, overcoming the gravity of the counterweight 310, causing the sensing swing block 300 to rotate, the sensing part 320 moves to the side of the mounting hole 112, the sensor 400 senses the sensing swing block 300, and the stamping machine starts working.

[0021] Specifically, refer to Figures 1-2 As shown, the counterweight is provided with an arc-shaped limiting groove 311, and the lifting block 210 is provided with a limiting screw 211. The limiting screw 211 extends towards the counterweight and passes through the arc-shaped limiting groove 311 to limit the counterweight. In this embodiment, the arc-shaped limiting groove 311 and the limiting screw 211 work together to limit the rotation distance of the inductive pendulum block 300 under its own weight, thus preventing the counterweight 310 from fully extending into the mounting slot 111, which would prevent the stamping material from contacting the inductive pendulum block 300 when placed on the lifting plate.

[0022] Specifically, refer to Figures 1-2As shown, the elastic reset member 220 includes a reset spring 221. One end of the reset spring 221 is connected to one side of the mounting part 110, and the other end is connected to the lifting block 210. In this embodiment, when the stamping material is placed on the lifting plate before the stamping machine performs stamping, the reset spring 221 provides support, allowing the lifting plate to lift the stamping material. When the stamping machine is working, it overcomes the spring force, causing the lifting block 210 to rotate to avoid air leakage. After stamping is completed, the reset spring 221 drives the lifting block 210 to return to its original position to carry the next piece of stamping material.

[0023] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
