Description

Technical Field

[0001] This utility model relates to the field of punching technology, and in particular to a waste-shaking device. Background Technology

[0002] In the sheet metal processing of strip metal, one part of the strip forms the finished product, while the other part becomes scrap. The scrap needs to be separated from the strip to be discharged. This is typically achieved using a scrap-discharging device. Before separating the scrap from the strip, the device needs to push the scrap to bend it relative to the strip. In existing technology, a cylinder provides power to bend the scrap relative to the strip. However, the cylinder's movement efficiency is low, resulting in low efficiency for the scrap-discharging device. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a waste-discharging device that improves waste discharge efficiency.

[0004] This utility model provides a waste-shaking device, which includes a waste-shaking mechanism, a mold-closing mechanism, and a feeding mechanism. The waste-shaking mechanism includes a drive assembly, a stamping protrusion, and a waste-shaking slider. The waste-shaking slider has a waste-shaking hole, and the stamping protrusion is movably connected to the waste-shaking slider. The mold-closing mechanism includes a rotary driver and a cam. The cam has an outer peripheral surface that abuts against the stamping protrusion. The rotary driver is connected to the cam and can drive the cam to rotate around an axis perpendicular to a first direction, so that the cam pushes the stamping protrusion to move along the first direction and pushes the waste material on the strip located between the stamping protrusion and the waste-shaking slider, and is used to allow the waste material to extend into the waste-shaking hole. The drive assembly is connected to the waste-shaking slider and can drive the waste-shaking slider to move in a direction intersecting the first direction, so that the waste material is separated from the strip. The feeding mechanism is used to transport the strip between the stamping protrusion and the waste-shaking slider.

[0005] The waste-shaking device provided by this utility model has at least the following beneficial effects: When the stamping protrusion moves relative to the scrap slider, it can push the scrap on the strip so that the scrap bends relative to the strip. When the rotary driver drives the cam to rotate, the cam can drive the stamping protrusion to move so that the stamping protrusion can push the scrap. The cam has high motion efficiency. By driving the stamping protrusion to push the scrap through the cam, the scrap discharge efficiency can be improved.

[0006] In one embodiment of this implementation, the cam has a cam groove with opposite side walls, the outer peripheral surface of which forms one side wall of the cam groove, and the stamping protrusion slides in conjunction with the cam groove.

[0007] In one embodiment of this implementation, the waste-shaking mechanism further includes a pulley, which is rotatably connected to the stamping protrusion and abuts against the outer peripheral surface.

[0008] In one embodiment of this implementation, the waste-shaking mechanism further includes a linkage member that extends along a first direction. One end of the linkage member is connected to a stamping protrusion, and the other end is rotatably connected to a pulley.

[0009] In one embodiment of this implementation, the waste shaking mechanism further includes a support block, which is fixedly connected to the waste shaking slider along a first direction. The support block is used to abut against the material strip to provide support for the material strip.

[0010] In one embodiment of this implementation, the waste-shaking mechanism further includes a positioning plate, and a driving component can drive the waste-shaking slider to move along a second direction, which intersects with the first direction. A groove is provided on the positioning plate, which extends along the second direction, and the waste-shaking slider and the groove can be slidably engaged along the second direction.

[0011] In one embodiment of this implementation, the waste-shaking mechanism includes multiple stamped protrusions, and the waste-shaking slider has multiple waste-shaking holes, with the multiple stamped protrusions and multiple waste-shaking holes corresponding one-to-one.

[0012] In one embodiment of this implementation, the waste-shaking mechanism includes a positioning pin that extends along a first direction and is connected to a stamping protrusion. When the stamping protrusion moves relative to the waste-shaking slider, the positioning pin is used to insert into a hole on the material strip to position the material strip.

[0013] In one embodiment of this implementation, the feeding mechanism includes a rotating component that is rotatably connected to the waste shaking mechanism. The rotating component has a protrusion that extends in a direction perpendicular to the rotation axis of the rotating component. The protrusion is used to extend into a hole on the material belt, and the rotating component is used to convey the material belt.

[0014] In one embodiment of this implementation, the feeding mechanism further includes a fixed seat, an elastic element, and a pressure roller. The fixed seat is fixed relative to the shaking mechanism. The rotating element and the pressure roller are rotatably mounted on the fixed seat. The rotation axis of the pressure roller coincides with the axis of the rotating element. One end of the elastic element is connected to the fixed seat, and the other end is connected to the pressure roller. The elastic element is used to drive the pressure roller to push the material strip toward the rotating element.

[0023] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0024] Please see Figures 1 to 6 , Figure 1 This is a three-dimensional structural schematic diagram of the waste-shaking device 100 according to one embodiment of the present utility model; Figure 2 yes Figure 1 Side view of the waste-shaking device 100; Figure 3 yes Figure 1 A schematic diagram of the structure including the stamped protrusion 12 and the locating pin 18; Figure 4 yes Figure 1 A schematic diagram of the mold closing mechanism 20 and the stamping protrusion 12, etc. Figure 5 yes Figure 1 A schematic diagram of the mold closing mechanism 20, the positioning plate 17, and the rocking block 13, etc. Figure 6 yes Figure 5An enlarged schematic diagram of a portion of the structure. This utility model provides a waste-shaking device 100, which includes a waste-shaking mechanism 10, a mold-closing mechanism 20, and a feeding mechanism 30. The waste-shaking mechanism 10 includes a drive assembly 11, a stamping protrusion 12, and a waste-shaking slider 13. The waste-shaking slider 13 has a waste-shaking hole 131, and the stamping protrusion 12 is movably connected to the waste-shaking slider 13. The mold-closing mechanism 20 includes a rotary driver 21 and a cam 22. The cam 22 has an outer peripheral surface 222, which abuts against the stamping protrusion 12. The rotary driver 21 is connected to the cam 22 and can drive the cam 22 to rotate around an axis perpendicular to a first direction. The cam 22 is moved to push the stamping protrusion 12 to move along the first direction and push the waste material on the strip 200 located between the stamping protrusion 12 and the waste rocking slider 13, and to allow the waste material to extend into the waste rocking hole 131. The drive assembly 11 is connected to the waste rocking slider 13 and can drive the waste rocking slider 13 to move in a direction intersecting the first direction, so as to separate the waste material from the strip 200. The feeding mechanism 30 is used to convey the strip 200 between the stamping protrusion 12 and the waste rocking slider 13.

[0025] Specifically, the first direction is parallel to the Z direction, the second direction is parallel to the Y direction, the stamping protrusion 12 and the waste rocker 13 are arranged along the Z direction, the stamping protrusion 12 and the waste rocker 13 are slidably connected along the Z direction, the axis of the waste rocker hole 131 is parallel to the Z direction, the feeding mechanism 30 conveys the material strip 200 along the X direction to the space between the stamping protrusion 12 and the waste rocker 13, the axis of the outer peripheral surface 222 of the cam 22 is parallel to the X direction, the rotation axis of the cam 22 is parallel to the X direction, and the cam 22 is located on one side of the stamping protrusion 12 along the Z direction. In some embodiments, the waste-shaking mechanism 10 further includes a guide rail 19 and a spring. The guide rail 19 is located between the stamping protrusion 12 and the waste-shaking slider 13 and is movably connected to the waste-shaking slider 13 in the Z direction. The spring is connected to the guide rail 19 and can provide a force in the Z direction to the guide rail 19. The guide rail 19 extends in the X direction and has a support surface perpendicular to the Z direction and a guide surface perpendicular to the Y direction. The support surface and the guide surface are used to abut against the strip 200.

[0026] Understandably, the support surface of the guide rail 19 can abut against the strip 200 from the side of the strip 200 toward the scrap slider 13, so that the strip 200 is supported by the guide rail 19. When the stamping protrusion 12 moves toward the scrap slider 13 in the Z direction, the stamping protrusion 12 can bend the scrap so that the scrap is located on the side of the strip 200 toward the scrap slider 13 in the Z direction. The guide rail 19 can be pushed and move toward the scrap slider 13 in the Z direction, and the spring is compressed so that the strip 200 moves closer to the scrap slider 13 in the Z direction, and the bent scrap extends into the scrap hole 131. The hole wall of the scrap hole 131 can abut against the scrap. The drive assembly 11 can drive the scrap slider 13 to reciprocate in the Y direction, so that the scrap is repeatedly bent relative to the strip 200, and the metal of the part where the scrap is connected to the strip 200 is fatigued, so that the part connecting the scrap and the strip 200 can break. When the stamped protrusion 12 moves away from the waste-shaking slider 13, the spring extends and pushes the guide rail 19, causing the guide rail 19 to drive the material belt 200 to move in the direction away from the waste-shaking slider 13. This helps reduce the risk of interference between the material belt 200 and the waste-shaking slider 13 during the conveying process. The guide surface can guide the movement of the material belt 200 in the X direction, and during the movement of the waste-shaking slider 13 in the Y direction, the waste-shaking slider 13 will generate a force on the material belt 200 in the Y direction. The guide surface can restrict the movement of the material belt 200 in the Y direction, which helps reduce the risk of the material belt 200 deviating from the stamped protrusion 12 during the conveying process.

[0027] It should be understood that during the rotation of cam 22 around an axis perpendicular to the Z direction, the stamping protrusion 12 can move relative to cam 22 along the outer peripheral surface 222 of cam 22. The distance between each point on the outer peripheral surface 222 of cam 22 and the rotation axis of cam 22 is different, which can cause the stamping protrusion 12 to move in a direction close to the rotation axis of cam 22, or to move in a direction away from the rotation axis of cam 22. Moreover, cam 22 is located on the side of stamping protrusion 12 along the Z direction, so that cam 22 can drive stamping protrusion 12 to move in the Z direction, so that stamping protrusion 12 can push the waste on the strip 200.

[0028] In the waste-shaking device 100 of this utility model, when the stamping protrusion 12 moves relative to the waste-shaking slider 13, it can push the waste on the material belt 200 so that the waste is bent relative to the material belt 200. When the rotating driver 21 drives the cam 22 to rotate, the cam 22 can drive the stamping protrusion 12 to move so that the stamping protrusion 12 can push the waste. The cam 22 has high movement efficiency. By driving the stamping protrusion 12 to push the waste through the cam 22, the waste discharge efficiency can be improved.

[0029] Please see Figure 1 and Figure 7 , Figure 7 yes Figure 1A schematic diagram of the structure of the cam 22, linkage 15, etc. In one embodiment of this implementation, the cam 22 has a cam groove 221, the cam groove 221 has opposite side walls, the outer peripheral surface 222 forms one side wall of the cam groove 221, and the stamping protrusion 12 slides in cooperation with the cam groove 221.

[0030] Specifically, on a plane perpendicular to the rotation axis of the cam 22, the projection of one side wall of the cam groove 221 is similar to the projection of the other side wall. It is understood that in some embodiments, a portion of the stamping protrusion 12 may extend into the cam groove 221 to slide in cooperation with it. The portion of the stamping protrusion 12 extending into the cam groove 221 is located between the two side walls of the cam groove 221. One side wall of the cam groove 221 can provide a force to the stamping protrusion 12 close to the rotation axis of the cam 22, while the other side wall of the cam groove 221 can provide a force to the stamping protrusion 12 away from the rotation axis of the cam 22. This ensures that the stamping protrusion 12 receives a driving force both during its movement toward and away from the rocking block 13, thus reducing the risk of the stamping protrusion 12 failing to move properly.

[0031] Please see Figure 7 In one embodiment of this implementation, the waste-shaking mechanism 10 further includes a pulley 14, which is rotatably connected to the stamping protrusion 12 and abuts against the outer peripheral surface 222.

[0032] Specifically, the rotation axis of pulley 14 is parallel to the rotation axis of cam 22. It can be understood that during the rotation of cam 22, cam 22 can drive stamping protrusion 12 to move in the Z direction through pulley 14, and pulley 14 can roll relative to cam 22 along the outer peripheral surface 222 of cam 22, which helps to reduce the friction between stamping protrusion 12 and cam 22.

[0033] Please see Figure 1 and Figure 7 In one embodiment of this implementation, the waste-shaking mechanism 10 further includes a linkage 15, which extends along a first direction. One end of the linkage 15 is connected to the stamping protrusion 12, and the other end is rotatably connected to the pulley 14.

[0034] Specifically, the linkage 15 extends along the Z direction. It can be understood that, on the one hand, by adjusting the distance of the linkage 15 extending along the Z direction, the stamping protrusion 12 can be connected to cams 22 of different sizes; on the other hand, by changing the distance of the linkage 15 extending along the Z direction, the stamping protrusion 12 can be connected to cams 22 with different rotation axes, which is beneficial to improving the applicability of the waste-shaking device 100.

[0035] Please see Figure 1 , Figure 5 and Figure 6In one embodiment of this implementation, the waste shaking mechanism 10 further includes a support block 16, which is fixedly connected to the waste shaking slider 13 along a first direction. The support block 16 is used to abut against the material belt 200 to provide support for the material belt 200.

[0036] Specifically, the support block 16 is disposed on one side of the waste rocker block 13 along the X direction, and the top side of the support block 16 is used to support the material strip 200. In a plane perpendicular to the Z direction, the projection of the support block 16 and the projection of the stamping protrusion 12 are arranged along the Y direction.

[0037] Understandably, when the stamping protrusion 12 pushes the scrap, the support block 16 provides support for the strip 200. The support block 16 and the stamping protrusion 12 work together to improve the bending effect of the scrap relative to the strip 200. In a plane perpendicular to the Z direction, the projections of the support block 16 and the stamping protrusion 12 are aligned along the Y direction, so that after the scrap is bent relative to the strip 200, it is located on one side of the support block 16 along the Y direction. Multiple scrap materials are arranged along the X direction on the strip 200. The support block 16 is located on one side of the scrap rocker block 13 along the X direction. After the scrap materials are bent relative to the strip 200, the feeding mechanism 30 can convey the strip 200 along the X direction so that the bent scrap materials move to the top side of the scrap rocker block 13 and the unbent scrap materials move to the top side of the support block 16. Subsequently, the stamping protrusion 12 moves downward to bend the scrap materials currently located on the top side of the support block 16. At the same time, it pushes the guide rail 19 downward to allow the scrap materials located on the top side of the scrap rocker block 13 to extend into the scrap rocker hole 131 and allow the scrap rocker block 13 to separate the scrap materials from the strip 200. With this arrangement, the process of bending the scrap materials and the process of separating the scrap materials from the strip 200 are performed in two positions, which helps to reduce the risk of interference between the stamping protrusion 12 and the scrap rocker block 13.

[0038] Please see Figure 1 , Figures 4 to 6 In one embodiment of this implementation, the waste-shaking mechanism 10 further includes a positioning plate 17, and the driving component 11 can drive the waste-shaking slider 13 to move along a second direction. The second direction intersects with the first direction. The positioning plate 17 is provided with a sliding groove 171, which extends along the second direction. The waste-shaking slider 13 and the sliding groove 171 can be slidably engaged along the second direction.

[0039] Specifically, the groove 171 has a groove wall perpendicular to the X direction. A portion of the waste-shaking slider 13 extends into the groove 171, and this portion slides against the groove wall. It is understood that the groove wall of the groove 171 guides the movement of the waste-shaking slider 13 along the Y direction and restricts its movement along the X direction. The placement of the waste-shaking slider 13 within the groove 171 helps reduce the risk of its position shifting in the X direction, thereby reducing the risk of waste failing to enter the waste-shaking hole 131.

[0040] Please see Figure 1 , Figures 4 to 6 In one embodiment of this implementation, the waste-shaking mechanism 10 includes a plurality of stamped protrusions 12, and the waste-shaking slider 13 is provided with a plurality of waste-shaking holes 131, with the plurality of stamped protrusions 12 and the plurality of waste-shaking holes 131 corresponding one-to-one.

[0041] Specifically, there are two stamping protrusions 12 and two waste-shaking holes 131 on the waste-shaking slider 13. This arrangement allows the waste-shaking device 100 to simultaneously bend multiple waste materials on the material strip 200 and to simultaneously separate multiple waste materials on the material strip 200, which helps to improve the efficiency of the waste-shaking device 100.

[0042] Please see Figure 1 , Figure 3 and Figure 4 In one embodiment of this implementation, the waste shaking mechanism 10 includes a positioning pin 18, which extends along a first direction and is connected to a stamping protrusion 12. When the stamping protrusion 12 moves relative to the waste shaking slider 13, the positioning pin 18 is used to extend into a hole on the material strip 200 to position the material strip 200.

[0043] Specifically, the positioning pins 18 extend along the Z direction, and multiple positioning pins 18 are provided, arranged at intervals along the X direction. It can be understood that the positioning pins 18 are fixed relative to the stamping protrusions 12. When the positioning pins 18 extend into the holes on the strip 200, they can correct the relative position of the strip 200 and the stamping protrusions 12, and also fix the strip 200 and the stamping protrusions 12 relative to each other. This reduces the risk that the stamping protrusions 12 may fail to push the scrap material due to the relative position of the strip 200 and the stamping protrusions 12 not conforming to expectations.

[0044] Please see Figures 1 to 2 In one embodiment of this implementation, the feeding mechanism 30 includes a rotating member 31, which is rotatably connected to the waste shaking mechanism 10. The rotating member 31 is provided with a protrusion 32, which extends in a direction perpendicular to the rotation axis of the rotating member 31. The protrusion 32 is used to extend into a hole on the material belt 200, and the rotating member 31 is used to convey the material belt 200.

[0045] Specifically, in some embodiments, both the waste-shaking mechanism 10 and the feeding mechanism 30 are mounted on a frame. A rotating member 31 is rotatably mounted on the frame about an axis parallel to the Y direction. Multiple protrusions 32 are provided, arranged circumferentially at intervals along the rotation axis of the rotating member 31. It is understood that the material belt 200 has multiple spaced waste materials, requiring the feeding mechanism 30 to convey the material belt 200 at a preset step distance so that the multiple waste materials move to the bottom side of the stamping protrusion 12, allowing the stamping protrusion 12 to bend the multiple waste materials sequentially. When the protrusions 32 on the rotating member 31 extend into the holes on the material belt 200, the relative sliding between the material belt 200 and the rotating member 31 during rotation is reduced, which facilitates the feeding mechanism 30 conveying the material belt 200 at a preset step distance, thereby reducing the risk that the stamping protrusion 12 will fail to bend the waste materials.

[0046] Please see Figure 1 and Figure 2 In one embodiment of this implementation, the feeding mechanism 30 further includes a fixed base 33, an elastic element, and a pressure roller 34. The fixed base 33 is fixed relative to the waste shaking mechanism 10. The rotating element 31 and the pressure roller 34 are rotatably mounted on the fixed base 33. The rotation axis of the pressure roller 34 coincides with the axis of the rotating element 31. One end of the elastic element is connected to the fixed base 33, and the other end is connected to the pressure roller 34. The elastic element is used to drive the pressure roller 34 to push the material strip 200 toward the rotating element 31.

[0047] Specifically, the feeding mechanism 30 also includes a connecting rod 35. One end of the connecting rod 35 is rotatably connected to the fixed seat 33 about an axis parallel to the Y direction, and the other end is rotatably mounted with a pressure roller 34. The rotation axis of the pressure roller 34 is parallel to the Y direction. One end of a spring is connected to the fixed seat 33, and the other end is connected to the connecting rod 35. The spring can drive the connecting rod 35 to rotate so that the connecting rod 35 drives the pressure roller 34 to approach the rotating part 31.

[0048] Understandably, the material belt 200 can pass between the pressure roller 34 and the rotating member 31. When the pressure roller 34 pushes the material belt 200 toward the rotating member 31, it can reduce the risk that the protrusion 32 on the rotating member 31 will exit through the hole on the material belt 200, which is beneficial for the feeding mechanism 30 to convey the material belt 200 at a preset step distance.

[0049] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
