An automatic waste collection structure for metal stamping dies

Abstract

This utility model belongs to the field of hardware processing technology and discloses an automatic waste collection structure for hardware stamping dies. It includes a base plate, a worktable fixedly mounted on the top of the base plate, and a lower die body fixedly mounted on the top of the worktable. This utility model, by setting up a sieve plate, a circular shaft, an elliptical block, and a metal shavings collection box, allows waste to fall through the waste hole into the top of the sieve plate. When the waste falls into the top of the sieve plate, the drive motor is activated, causing the circular shaft to rotate the elliptical block. This causes the elliptical block to press and push the bottom of the sieve plate, causing the sieve plate to rotate around a fixed axis. As the elliptical block continues to rotate, the sieve plate vibrates, dislodging metal shavings adhering to the surface of the waste. These metal shavings then fall through the sieve plate into the metal shavings collection box, while the waste falls into the waste collection box, thus classifying and collecting the waste and metal shavings.

Description

Technical Field

[0001] This utility model belongs to the field of hardware processing technology, specifically an automatic waste collection structure for hardware stamping dies. Background Technology

[0002] Metal stamping is a processing method that uses stamping dies and stamping equipment to apply pressure to metal sheets, causing them to undergo plastic deformation or separation, thereby obtaining parts or products with the required shape, size and properties.

[0003] During the stamping process of hardware parts, a large amount of waste and metal shavings are often generated. These wastes need to be collected for recycling. Although the stamping equipment of existing hardware parts production has the function of waste collection, it simply collects all the waste together without classifying the metal waste and metal shavings. As a result, a large amount of metal shavings are mixed in with the waste. Since metal shavings and larger pieces of waste differ in physical properties, chemical composition and subsequent processing technology, it is difficult to use uniform processing during recycling if they are not classified. This forces more manpower, resources and time to be invested in secondary sorting, which undoubtedly increases recycling costs and reduces recycling efficiency. Therefore, it is necessary to improve the process. Utility Model Content

[0004] The purpose of this invention is to address the above problems by providing an automatic waste collection structure for metal stamping dies, which has the advantage of separating metal chips.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic waste collection structure for metal stamping dies, comprising a base plate, a worktable fixedly mounted on the top of the base plate, a lower die body fixedly mounted on the top of the worktable, a waste hole opened inside the worktable, a fixed box fixedly connected to the top of the base plate, the top of the fixed box fixedly connected to the bottom of the worktable, a fixed shaft fixedly mounted on the left side inside the fixed box, a sieve plate movably sleeved on the outer surface of the fixed shaft, a drive motor fixedly mounted on the front of the fixed box, a round shaft fixedly connected to the other end of the output shaft of the drive motor, the rear end of the round shaft extending into the interior of the fixed box and movably sleeved with the inner wall of the fixed box, an elliptical block fixedly sleeved on the outer surface of the round shaft, the outer surface of the elliptical block movably connected to the bottom of the sieve plate, a metal shavings collection box movably mounted at the bottom of the inner cavity of the fixed box, a first baffle fixedly mounted on the top right side of the fixed box, and a waste collection box movably mounted on the right side of the top of the base plate.

[0006] As a preferred embodiment of this utility model, fixing blocks located below the sieve plate are fixedly installed on both the front and rear sides of the inner surface of the fixing box, and springs are fixedly installed on the top of the fixing blocks, with the top of the springs fixedly connected to the bottom of the sieve plate.

[0007] As a preferred embodiment of this utility model, a support frame is fixedly installed on the right side of the top of the workbench, a pneumatic cylinder is fixedly installed on the top of the support frame, the bottom end of the pneumatic cylinder passes through the support frame and is movably sleeved with the inner wall of the support frame, and the bottom end of the pneumatic cylinder is fixedly connected to the upper mold body.

[0008] As a preferred embodiment of this utility model, a round rod is movably sleeved inside the support frame, a connecting plate is fixedly connected to the right end of the round rod, and a cleaning brush is fixedly connected to the left end of the round rod.

[0009] As a preferred embodiment of this utility model, a power motor is fixedly installed on the right side of the top of the workbench, and a rotating shaft is fixedly connected to the other end of the output shaft of the power motor, with a rotating rod fixedly sleeved on the outer surface of the rotating shaft.

[0010] As a preferred embodiment of this invention, the right end of the rotating rod is hinged to a hinge rod, and the right end of the hinge rod is hinged to the bottom of the connecting plate.

[0011] As a preferred embodiment of this utility model, the workbench has a through hole located on the left side of the lower mold body, and a second baffle is fixedly installed on the top of the workbench.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, by setting up a sieve plate, a round shaft, an elliptical block, and a metal shavings collection box, allows waste to fall into the top of the sieve plate through the waste hole. When the waste falls into the top of the sieve plate, the drive motor is started, causing the round shaft to rotate, which in turn causes the elliptical block to squeeze and push the bottom of the sieve plate, causing the sieve plate to rotate around a fixed axis. As the elliptical block continues to rotate, the sieve plate vibrates, which shakes the metal shavings attached to the surface of the waste off, allowing the metal shavings to fall through the sieve plate into the metal shavings collection box. The waste will fall into the waste collection box, thus classifying and collecting the waste and metal shavings.

[0014] 2. This utility model, by setting up a round rod, a connecting plate, a cleaning brush, and a power motor, allows the lower mold body to be cleaned by starting the power motor, which causes the rotating shaft to rotate. At this time, the hinge rod will pull the connecting plate to the left, thereby driving the cleaning brush to the left through the round rod. This allows the cleaning brush to sweep the metal shavings on the top of the lower mold body through the through hole to the top of the sieve plate, and finally through the sieve plate into the interior of the metal shavings collection box.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 5As shown, this utility model provides an automatic waste collection structure for metal stamping dies, including a base plate 1, a workbench 2 fixedly installed on the top of the base plate 1, a lower die body 3 fixedly installed on the top of the workbench 2, a waste hole 4 opened inside the workbench 2, a fixed box 5 fixedly connected to the top of the base plate 1, the top of the fixed box 5 fixedly connected to the bottom of the workbench 2, a fixed shaft 6 fixedly installed on the left side inside the fixed box 5, a screen plate 7 movably sleeved on the outer surface of the fixed shaft 6, a drive motor 8 fixedly installed on the front of the fixed box 5, a round shaft 9 fixedly connected to the other end of the output shaft of the drive motor 8, the rear end of the round shaft 9 extending into the interior of the fixed box 5 and movably sleeved with the inner wall of the fixed box 5, an elliptical block 10 fixedly sleeved on the outer surface of the round shaft 9, the outer surface of the elliptical block 10 movably connected to the bottom of the screen plate 7, a metal shavings collection box 11 movably installed at the bottom of the inner cavity of the fixed box 5, a first baffle 12 fixedly installed on the top right side of the fixed box 5, and a waste collection box 13 movably installed on the right side of the top of the base plate 1.

[0023] During stamping, the waste material will fall through the waste hole 4 to the top of the screen plate 7. When the drive motor 8 starts, the round shaft 9 will drive the elliptical block 10 to rotate, causing the outer surface of the elliptical block 10 to press and push the bottom of the screen plate 7, causing the screen plate 7 to rotate upward around the fixed shaft 6. As the elliptical block 10 rotates continuously, it will cause the screen plate 7 to vibrate, causing the waste material on the top of the screen plate 7 to move along the top of the screen plate 7 and fall into the waste collection box 13. The metal chips that fall on the top of the screen plate 7 or are attached to the surface of the waste material will fall into the metal chip collection box 11 under the action of vibration.

[0024] Among them, fixing blocks 14 located below the sieve plate 7 are fixedly installed on both the front and rear sides of the inner surface of the fixing box 5. A spring 15 is fixedly installed on the top of the fixing block 14, and the top of the spring 15 is fixedly connected to the bottom of the sieve plate 7.

[0025] When the sieve plate 7 rotates upward, the spring 15 will be stretched, which will cause the spring 15 to drive the sieve plate 7 to rotate downward under the elastic recovery action.

[0026] Among them, a support frame 16 is fixedly installed on the right side of the top of the workbench 2, and a pneumatic cylinder 17 is fixedly installed on the top of the support frame 16. The bottom end of the pneumatic cylinder 17 passes through the support frame 16 and is movably sleeved with the inner wall of the support frame 16. The bottom end of the pneumatic cylinder 17 is fixedly connected to the upper mold body 18.

[0027] The operator activates the pneumatic cylinder 17, causing the upper mold body 18 to move downwards, thereby enabling stamping processing.

[0028] The support frame 16 has a circular rod 19 movably connected inside. The right end of the circular rod 19 is fixedly connected to a connecting plate 20, and the left end of the circular rod 19 is fixedly connected to a cleaning brush 21.

[0029] When the connecting plate 20 moves to the left, it will drive the cleaning brush 21 to move to the left through the round rod 19, so that the cleaning brush 21 can clean the metal shavings on the top of the lower mold body 3 and prevent the metal shavings from affecting the stamping of the hardware parts.

[0030] Among them, a power motor 22 is fixedly installed on the right side of the top of the workbench 2, and a rotating shaft 23 is fixedly connected to the other end of the output shaft of the power motor 22. A rotating rod 24 is fixedly sleeved on the outer surface of the rotating shaft 23.

[0031] The operator starts the power motor 22, which causes the rotating shaft 23 to drive the rotating rod 24 to rotate.

[0032] The right end of the rotating rod 24 is hinged to a hinge rod 25, and the right end of the hinge rod 25 is hinged to the bottom of the connecting plate 20.

[0033] When the rotating shaft 23 drives the rotating rod 24 to rotate, it will drive the connecting plate 20 to move to the left through the hinge rod 25, thereby causing the round rod 19 to move to the left.

[0034] The workbench 2 has a through hole 26 located on the left side of the lower mold body 3 inside, and a second baffle 27 is fixedly installed on the top of the workbench 2.

[0035] By providing through holes 26, the cleaning brush 21 can push metal shavings through the through holes 26 to the top of the sieve plate 7 when it moves to the left.

[0036] Working principle and usage process of this utility model:

[0037] The operator places the material on top of the lower mold body 3, and then starts the pneumatic cylinder 17, which drives the upper mold body 18 downward to press the material. The waste material will fall into the top of the screen plate 7 through the waste hole 4. After the drive motor 8 is started, the round shaft 9 will drive the elliptical block 10 to rotate, which will cause the elliptical block 10 to squeeze and push the bottom of the screen plate 7, causing the screen plate 7 to rotate upward. When the screen plate 7 rotates upward, the spring 15 will be stretched, and the spring 15 will drive the screen plate 7 to return to its original position under the elastic recovery action. This process is repeated. As the elliptical block 10 rotates, the screen plate 7 will vibrate, which will shake off the metal chips attached to the surface of the waste material. The metal chips will fall into the metal chip collection box 11 through the screen plate 7, while the waste material will fall into the waste collection box 13, thus classifying and collecting the waste material and metal chips.

[0038] After stamping is completed, when it is necessary to clean the metal shavings on the top of the lower die body 3, the power motor 22 can be started, causing the rotating shaft 23 to drive the rotating rod 24 to rotate, thereby causing the hinge rod 25 to move. The hinge rod 25 will pull the connecting plate 20 to move to the left, and then drive the cleaning brush 21 to move to the left through the round rod 19, so that the cleaning brush 21 can sweep the metal shavings on the top of the lower die body 3 through the through hole 26 to the top of the screen plate 7, so that the metal shavings fall into the metal shavings collection box 11 through the screen plate 7.
