Description

Technical Field

[0001] This utility model relates to the technical field of stamping dies, and in particular to a die stamping waste discharge mechanism. Background Technology

[0002] In existing stamping production, waste material is generated during each stamping process. This waste material is discharged through the waste hole and accumulates at the bottom of the stamping die. Therefore, the machine needs to be stopped periodically to remove the waste material, otherwise normal production will be affected. Furthermore, the accumulation of waste material inside the die can cause damage. However, stopping the machine to remove waste material disrupts normal production and reduces efficiency. If the removal is not thorough, waste material blockage can damage the die and pose a safety hazard to workers. Therefore, existing stamping dies are equipped with scrap guide channels on the lower die to discharge scrap outside the die. In order to allow the scrap to be discharged smoothly, a certain slope is set. After the scrap falls into the scrap guide channel, it automatically flows down the scrap guide channel and is then received by the scrap line outside the lower die and discharged to a designated location for collection. Workers do not need to clean the scrap, so the scrap will not accumulate on the lower die. However, the existing scrap guide channels have the following problems: (1) The scrap guide channel is inclined and set at the bottom of the lower die base. The scrap guide channel is fixed and cannot be moved. However, when the space of the lower die base is limited, such as when the die length is long or the height is small, the inclination angle of the scrap guide channel will be insufficient, which will eventually cause the scrap on the scrap guide channel to not slide out automatically, and the scrap will continue to accumulate on the scrap guide channel. To address the aforementioned issues, some companies have developed waste discharge mechanisms. For example, Chinese Patent Publication No. CN104308026A, published on January 28, 2015, discloses a waste recycling system for stamping dies. This system includes a camshaft, a sliding plate, and a waste recycling bin. The camshaft is connected to the sliding plate via its cam, and the sliding plate can slide on the worktable. The upper end of the other end of the sliding plate has an inclined plate. Below the inclined plate is a curved inclined plate. The camshaft is driven by a motor, and it uses a cam structure to drive the sliding plate to reciprocate, transporting the waste generated in the waste hole to the waste recycling bin to prevent waste accumulation. However, the above-mentioned waste recycling system adds a motor, which leads to a more complex structure and increased cost of the entire stamping die. Utility Model Content

[0003] The purpose of this utility model is to provide a die stamping waste discharge mechanism that is simple in structure, low in cost, and can efficiently discharge waste.

[0004] The purpose of this utility model is achieved as follows:

[0005] A die stamping waste discharge mechanism includes an upper die assembly and a lower die assembly arranged vertically. The upper die assembly has a pressure rod, and the lower die assembly has a waste receiving cavity and a waste outlet communicating with the waste receiving cavity. The front and rear sides of the waste receiving cavity are open, and a waste guide groove is slidably arranged inside the waste receiving cavity. The waste guide groove is inclined inside the waste receiving cavity and located below the waste outlet. A pusher arm is rotatably arranged on the lower die assembly about a horizontal line. A return spring is provided between the lower die assembly and the lower end of the pusher arm. The front end and rear end of the return spring are respectively connected to the lower die assembly and the pusher arm. The lower end of the pusher arm is fixedly connected to the top end of the waste guide groove. When the upper mold assembly moves downward towards the lower mold assembly, the pressure rod presses down on the upper end of the pusher arm, causing the lower end of the pusher arm to rotate backward and slide the waste guide groove towards the rear of the waste receiving cavity. The reset spring is stretched. When the upper mold assembly moves upward away from the lower mold assembly, the pressure rod moves away from the upper end of the pusher arm, and the reset spring pulls the lower end of the pusher arm to rotate forward. The pusher arm drives the waste guide groove to slide towards the front of the waste receiving cavity, and the waste on the waste guide groove automatically slides down and out of the waste guide groove. This invention utilizes the pressure rod and reset spring on the upper mold assembly to drive the pusher arm to rotate forward or backward, thereby moving the waste guide groove forward or backward. The waste on the waste guide groove will automatically slide out of the waste guide groove as it moves forward, thus achieving automatic waste discharge without manual cleaning, preventing waste accumulation, improving production efficiency, and avoiding damage to the mold.

[0006] The present invention can be further improved in the following ways.

[0007] The lower end of the pusher arm is provided with a horizontal connecting rod, and the connecting rod is provided with at least two connecting blocks, which are fixedly connected to the waste guide chute.

[0008] A limiting groove is provided at the rear end of the waste receiving chamber corresponding to the position of the connecting rod. The limiting groove is located on the front side of the connecting rod and prevents the connecting rod from sliding forward. Due to the limiting groove, after the connecting rod collides with the limiting groove, the waste guide channel suddenly stops moving forward, which will eventually cause the waste on the waste guide channel to slide out of the waste guide channel quickly due to inertia.

[0009] The limiting groove is stepped. Under the action of the reset spring, the connecting rod slides along the limiting groove. Due to the sudden change and stop of the position of the connecting rod, the waste guide groove will suddenly stop moving forward, which will cause the waste on the waste guide groove to slide out of the waste guide groove faster due to inertia.

[0010] The front and rear ends of the reset spring are fixedly connected to the inner wall of the waste receiving chamber and the connecting rod, respectively.

[0011] A support roller is rotatably provided on the inner bottom surface of the waste receiving chamber. The support roller is close to the lower end of the waste guide groove, and the bottom surface of the waste guide groove sits on the wheel surface of the support roller, thereby making the waste guide groove slide smoothly and with good sliding effect.

[0012] At least two fixed seats are provided at intervals along the left and right direction of the waste receiving chamber on the inner bottom surface of the waste receiving chamber. At least two support rollers are rotatably provided on the fixed seats, so that the waste guide groove slides smoothly and has a good sliding effect.

[0013] The material pusher arm is located at the rear of the waste receiving chamber.

[0014] The bottom end of the waste guide trough extends from the front side of the waste receiving chamber, making it easier for the external waste bag to catch the waste.

[0015] The bottom of the waste guide chute is equipped with a detachable extended tray. This invention extends the length of the tray, making it easier for an external waste bag to catch the waste.

[0016] The pusher arm is Γ-shaped. The design of this utility model is reasonable, and the upper end of the pusher arm can be easily pressed down and rotated.

[0017] A clearance groove is provided at the rear end of the waste receiving chamber corresponding to the position of the pusher arm, and the pusher arm rotates within the clearance groove.

[0018] The pressure bar is located directly above the upper end of the pusher arm.

[0019] The width of the waste guide channel is matched with the width of the waste receiving cavity, and the waste guide channel can completely catch the waste falling from the waste outlet, resulting in good material receiving effect.

[0020] The beneficial effects of this utility model are as follows:

[0021] 1. This utility model utilizes the pressure rod and reset spring on the upper mold assembly to drive the pusher arm to rotate forward or backward, thereby driving the waste guide groove to move forward or backward. The waste on the waste guide groove will automatically slide out of the waste guide groove as it moves forward, thus achieving automatic waste discharge without manual cleaning, preventing waste accumulation, improving production efficiency, and avoiding damage to the mold.

[0022] 2. The waste receiving chamber of this utility model is provided with a limiting groove at the rear end. After the connecting rod collides with the limiting groove, the waste guide channel suddenly stops moving forward, which will eventually cause the waste on the waste guide channel to slide out of the waste guide channel quickly due to inertia.

[0035] Example 1, as Figures 1 to 11As shown, a die stamping waste discharge mechanism includes an upper die assembly 1 and a lower die assembly 2 arranged vertically. The upper die assembly 1 is provided with a pressure rod 11, and the lower die assembly 2 is provided with a waste receiving cavity 21 and a waste outlet 20 communicating with the waste receiving cavity 21. The front and rear sides of the waste receiving cavity 21 are open, and a waste guide groove 3 is slidably provided in the waste receiving cavity 21. The waste guide groove 3 is inclined in the waste receiving cavity 21 and located below the waste outlet 20. A pusher arm 31 is rotatably provided on the lower die assembly 2 about a horizontal line. A return spring 34 is provided between the lower die assembly and the lower end of the pusher arm. The front end and rear end of the return spring 34 are respectively The lower end of the pusher arm 31 is fixedly connected to the lower die assembly 2 and the upper end of the pusher arm 31. The lower end of the pusher arm 31 is fixedly connected to the top end of the waste guide groove 3. When the upper die assembly 1 moves downward toward the lower die assembly 2, the pressure rod 11 presses down on the upper end of the pusher arm 31, and the lower end of the pusher arm 31 rotates backward and drives the waste guide groove 3 to slide toward the rear side of the waste receiving cavity 21. The reset spring 34 is stretched. When the upper die assembly 1 moves upward away from the lower die assembly 2, the pressure rod 11 moves away from the upper end of the pusher arm 31, and the reset spring 34 pulls the lower end of the pusher arm 31 to rotate forward. The pusher arm 31 drives the waste guide groove 3 to slide toward the front side of the waste receiving cavity 21.

[0036] This is a more specific technical solution of the present invention.

[0037] The lower end of the pusher arm 31 is provided with a horizontal connecting rod 32, and the connecting rod 32 is provided with at least two connecting blocks 33, which are fixedly connected to the waste guide trough 3.

[0038] A limiting groove 22 is provided at the rear end of the waste receiving chamber 21 corresponding to the position of the connecting rod 32. The limiting groove 22 is located on the front side of the connecting rod 32 and prevents the connecting rod 32 from sliding forward.

[0039] The front and rear ends of the reset spring 34 are fixedly connected to the inner wall of the waste receiving chamber 21 and the connecting rod 32, respectively.

[0040] A support roller 25 is rotatably provided on the inner bottom surface of the waste receiving chamber 21. The support roller 25 is close to the lower end of the waste guide 3, and the bottom surface of the waste guide 3 sits on the wheel surface of the support roller 25.

[0041] At least two fixed seats 24 are provided at intervals along the left and right directions of the waste receiving chamber 21 on the inner bottom surface of the waste receiving chamber 21, and at least two support rollers 25 are rotatably provided on the fixed seats 24.

[0042] The pusher arm 31 is rotatably located on the rear side of the waste receiving chamber 21.

[0043] The limiting groove 22 is stepped.

[0044] The bottom end of the waste guide trough 3 extends from the front side of the waste receiving chamber 21.

[0045] The bottom end of the waste guide chute 3 is provided with a detachable extension tray 35.

[0046] The pusher arm 31 is in the shape of a Γ.

[0047] A clearance groove 23 is provided at the rear end of the waste receiving chamber 21, corresponding to the position of the pusher arm 31.

[0048] The pressure rod 11 is located directly above the upper end of the pusher arm 31.

[0049] The width of the waste guide channel 3 is matched with the width of the waste receiving cavity 21.

[0050] The working principle of this utility model is as follows:

[0051] When the mold is closed and the upper mold assembly 1 moves downward toward the lower mold assembly 2, the upper mold assembly 1 drives the pressure rod 11 to descend. The pressure rod 11 presses down on the upper end of the pusher arm 31, and the lower end of the pusher arm 31 rotates backward. The lower end of the pusher arm 31 drives the connecting rod 32, the connecting block 33, and the waste guide groove 3 to slide toward the rear side of the waste receiving cavity 21. At this time, the reset spring 34 is stretched, and the waste generated during the stamping of the upper mold assembly 1 and the lower mold assembly 2 will fall from the waste outlet 20 onto the waste guide groove 3.

[0052] When the mold opens and the upper mold assembly 1 moves upward away from the lower mold assembly 2, the upper mold assembly 1 drives the pressure rod 11 to rise. The pressure rod 11 moves away from the upper end of the pusher arm 31, and the reset spring 34 returns to its original state. The reset spring 34 pulls the connecting rod 32, the connecting block 33, the waste guide groove 3, and the lower end of the pusher arm 31 to rotate forward. The pusher arm 31 drives the waste guide groove 3 to slide towards the front of the waste receiving cavity 21. Due to inertia, the waste on the waste guide groove will automatically slide out of the waste guide groove as it moves forward. Furthermore, when the connecting rod 32 collides with the limiting groove 22, the sudden change and stop of the position of the connecting rod 32 will cause the waste guide groove 3 to suddenly stop moving forward, ultimately causing the waste on the waste guide groove 3 to quickly slide out of the waste guide groove 3 due to inertia.
