Detailed implementation mode

[0036] In order to make the technical problems, technical solutions and beneficial effects solved by the invention more clear and understandable, the following further describes the invention in conjunction with the drawings and embodiments.

[0037] Embodiment 1

[0038] As Figures 1 to 6 shown, this embodiment provides a hardware part auxiliary stamping device, including a stamping assembly 10 and a collection assembly. The collection assembly is arranged below the dropping hole 19 and is used to collect the hardware parts falling from the dropping hole 19. The stamping assembly 10 includes a frame 11, a chassis 12, a turntable 13 and a stamping unit 17.

[0039] An installation bracket 115 is fixed on the frame 11. The chassis 12 is arranged on the frame 11. A sleeve 18 is fixed under the chassis 12. The sleeve 18 passes through the frame 11. At least one dropping hole 19 is opened on the chassis 12. A hole corresponding to the position of the dropping hole 19 is opened on the frame 11.

[0040] The turntable 13 is rotatably arranged above the chassis 12. A rotating shaft 110 is fixed under the turntable 13. The rotating shaft 110 is sleeved in the sleeve 18. The rotating shaft 110 is driven by a first driving source. A plurality of stamping holes 111 are arranged on the turntable 13 at equal circumferential intervals. The aperture of the stamping holes 111 gradually increases from top to bottom. The dropping hole 19 is arranged below the stamping holes 111. The heights of the turntable 13 and the chassis 12 relative to the frame 11 are fixed. In particular, the positions of the rotating shaft 110 and the first driving source are fixed and can be fixed by means of a fixing frame or the like. The first driving source is a motor. The motor drives the rotating shaft 110 to rotate. The rotating shaft 110 drives the turntable 13 to rotate. The stamping holes 111 on the turntable 13 also rotate accordingly. The stamping unit 17 works in an intermittent manner in cooperation with the circumferentially distributed stamping holes 111, and the working efficiency is higher.

[0041] Above a stamping hole 111, there is a stamping unit 17. When the turntable 13 rotates, it is ensured that the stamping unit 17 is always directly opposite a stamping hole 111 below. Refer to Figure 6 , the stamping unit 17 includes a hydraulic cylinder 171, a lifting block 172, a central wedge block 173 and two side pressing blocks 174. The hydraulic cylinder 171 is fixed on the mounting frame 115. The lifting block 172 is fixedly connected under the hydraulic cylinder 171. The central wedge block 173 is fixed under the lifting block 172. A first spring 175 is fixed above the two side pressing blocks 174. The top of the first spring 175 is fixed on the lifting block 172. The first spring 175 can be compressed between the side pressing block 174 and the lifting block 172. The inner side walls of the two side pressing blocks 174 abut against the outer wall of the central wedge block 173. The other outer walls of the two side pressing blocks 174 can abut against the hole wall of the stamping hole 111. The side wall of the side pressing block 174 in contact with the central wedge block 173 includes a first inclined wall 1741, a shoulder wall 1742 and a second inclined wall 1743 connected in sequence. The first inclined wall 1741 and the second inclined wall 1743 have the same slope and incline towards the center line of the central wedge block 173. The shoulder wall 1742 inclines away from the center line of the central wedge block 173. The central wedge block 173 includes an upper tapered block 1731 and a lower tapered block 1732 of an integral structure. The outer wall of the upper tapered block 1731 abuts against the first inclined wall 1741. The outer walls of the lower tapered block 1732 abut against the shoulder wall 1742 and the second inclined wall 1743. The side pressing block 174 moves along the outer wall of the central wedge block 173. In the natural state, the bottom wall height of the central wedge block 173 is greater than the bottom wall heights of the two side pressing blocks 174.

[0042] The material to be stamped can be rectangular or cross-shaped. Place the material on the stamping hole 111, rotate the turntable 13, and turn the material to directly below the stamping unit 17. The hydraulic cylinder 171 drives the lifting block 172 to move downward rapidly. Since the bottom wall height of the central wedge block 173 is greater than the bottom wall height of the two side pressing blocks 174, the two side pressing blocks 174 first contact the material and press the material into the stamping hole 111. The two side pressing blocks 174 drive the material to first contact the chassis 12. The lifting block 172 continues to press downward, the first spring 175 is compressed, the central wedge block 173 continues to move downward, and the lower conical block 1732 slides downward along the second inclined wall 1743. The lower conical block 1732 extrudes the two side pressing blocks 174 outward, and the two side pressing blocks 174 move outward. When the central wedge block 173 contacts the chassis 12, the other outer walls of the two side pressing blocks 174 abut or almost abut the hole wall of the stamping hole 111. At this time, the material is stamped into a hardware part in the shape of the stamping hole 111. The hydraulic cylinder 171 drives the lifting block 172 to move upward, and the stamping is completed. The turntable 13 drives the hardware part to continue rotating. When the hardware part rotates to the dropping hole 19, the hardware part drops from the dropping hole 19 and is collected by the collection assembly.

[0043] The stamping unit 17 includes a second spring 176. The two ends of the second spring 176 are respectively fixed on the two side pressing blocks 174. The central wedge block 173 is provided with a through hole 177 for the second spring 176 to pass through. Under the action of the second spring 176, the side pressing block 174 always abuts against the outer wall of the central wedge block 173. Under the pulling of the second spring 176, even if the central wedge block 173 and the side pressing block 174 have relative displacement, the side pressing block 174 can always move along the first inclined wall 1741 and the second inclined wall 1743.

[0044] Reference Figure 2 , a bearing 112 and a gear 113 are provided on the sleeve 18. The chassis 12 is installed on the frame 11 through the bearing 112. The gear 113 is provided below the bearing 112. A tooth shaft 114 meshing with the gear 113 is provided on one side of the gear 113. The position of the tooth shaft 114 is fixed and driven by a second driving source. The second driving source drives the tooth shaft 114, the tooth shaft 114 drives the gear 113 and the sleeve 18 to rotate, and further drives the chassis 12 to rotate relative to the frame 11.

[0045] Reference Figure 3 , a plurality of platform support areas 121 are provided on the surface of the chassis 12. The heights of the plurality of platform support areas 121 are different. Rotate the platform support areas 121 with different heights to directly below the stamping unit 17 to realize fine adjustment of the distance between the chassis 12 and the turntable 13, and realize fine adjustment of the top diameter and the bottom diameter of the hardware part. Each platform support area 121 is provided with a dropping hole 19 to ensure that stamping and dropping are completed under the same height condition.

[0046] An annular groove 14 is formed in the chassis 12, and a number of rolling balls 15 are defined in the annular groove 14. An annular guide rail 16 is formed at the bottom of the turntable 13, and the rolling balls 15 rotate along the annular guide rail 16. Through this setting, the relative rotational position of the chassis 12 and the turntable 13 is ensured, and the dropping hole 19 is always located directly below the punching hole 111.

[0047] The collecting assembly includes a collecting box, and the hardware parts falling out from the dropping hole 19 directly fall into the collecting box. Of course, the collecting assembly can also include a collecting pipeline, and the hardware parts falling out from the dropping hole 19 fall into the collecting pipeline and finally fall into the collecting box.

[0048] Embodiment 2

[0049] As Figures 1 to 6 shown, on the basis of Embodiment 1, this embodiment provides a stamping unit 17. A plurality of rounded corner movable blocks 116 are provided at the bottom of the punching hole 111. The rounded corner movable blocks 116 are fixed to the bottom of the turntable 13 through torsion springs 117. Rounded corner structures 118 matching the shapes of the rounded corner movable blocks 116 are provided at the bottoms of the two side pressing blocks 174. In the case of not being stressed, the rounded corner movable blocks 116 do not contact the chassis 12. When the rounded corner movable blocks 116 are squeezed by the central wedge block 173 and the two side pressing blocks 174, the bottoms of the rounded corner movable blocks 116 abut against the chassis 12.

[0050] During stamping, the bottom of the side pressing block 174 drives the material to squeeze the rounded corner movable block 116, and the bottom of the rounded corner movable block 116 abuts against the chassis 12 to achieve rounded corner stamping. When the stamping is completed, under the reset action of the torsion spring 117, the rounded corner movable blocks 116 do not contact the chassis 12, ensuring the normal rotation of the turntable 13.

[0051] Refer to Figure 4 , a first cylinder 119 is fixedly provided on the mounting frame 115. A push block 120 is fixed to the bottom of the first cylinder 119. The push block 120 is arranged above a punching hole 111, and the dropping hole 19 is arranged below the punching hole 111. After stamping is completed, the turntable 13 drives the hardware part to rotate to below the push block 120, and the first cylinder 119 pushes the push block 120 downward, and the push block 120 pushes the hardware part out of the punching hole 111. This embodiment can stamp hardware parts with one or more rounded corners at the bottom.

[0052] Embodiment 3

[0053] As Figures 7 to 9 shown, on the basis of Embodiment 1, this embodiment provides a feeding assembly 20 for conveying materials to the position of the punching hole 111.

[0054] The feeding component 20 includes two juxtaposed conveyor chain groups 21. A number of equidistant conveyor plates 22 are fixed on the conveyor chain groups 21. The conveyor plates 22 on the two conveyor chain groups 21 are aligned for up-and-down conveyance. Materials are conveyed up and down between two conveyor plates 22 at the same height. On one side of the two conveyor chain groups 21, there is a first conveying rack 23. A linear movement module 24 is provided on the first conveying rack 23. A movable conveying support 25 is provided on the linear movement module 24. A conveying plate 26 at the same height as a group of conveyor plates 22 is provided on the conveying support 25. The conveying plate 26 is at the same height as the turntable 13. A first pushing component for pushing materials from the conveying plate 26 to the punching hole 111 is provided on the conveying support 25.

[0055] The feeding component 20 includes a lever 28. The lever 28 is arranged between the conveyor plates 22 of the two conveyor chain groups 21. The lever 28 is movable and is used to push the materials on the conveyor plate 22 onto the conveying plate 26.

[0056] On the other side of the two conveyor chain groups 21, there is a second conveying rack 29. A moving channel 210 is formed between the second conveying racks 29. A limiting plate 211 is fixed on one side of the moving channel 210, and a conveyor belt 212 is provided on the other side. A second pushing component 213 is provided in the moving channel 210. The second pushing component 213 is used to push the materials on the moving channel 210 onto the conveyor plate 22.

[0057] The second pushing component 213 includes a fixed frame 2131, a linear moving member 2132, a lifting member 2133, and a pushing block 2134. The position of the fixed frame 2131 is fixed. The linear moving member 2132 is fixed on the fixed frame 2131. The lifting member 2133 is vertically fixed at the movable end of the linear moving member 2132. The pushing block 2134 is fixed on the linear moving member 2132.

[0058] The structure of the first pushing component is similar to that of the second pushing component 213. The first pushing component is fixed on the conveying support 25 and also completes the pushing through horizontal movement and vertical movement.

[0059] Materials are conveyed from the conveyor belt 212. When conveyed to the moving channel 210, one side abuts against the limiting plate 211, and the direction of the materials is straightened. The pushing block 2134 on the second pushing component 213 moves upward and extends out of the moving channel 210, and pushes the materials between the two conveyor chain groups 21. The materials are placed between two conveyor plates 22 at the same height. The two conveyor chain groups 21 drive the materials to move upward. When moving up to the same height as the conveying plate 26, the lever 28 pushes the materials onto the conveying plate 26. The conveying plate 26 moves through the linear movement module 24, approaches the turntable 13, and is then pushed to the punching hole 111 by the first pushing component.

[0060] The linear moving part 2132 in this embodiment has the same function as the linear moving module 24. The linear moving module 24, the linear moving part 2132, and the lifting part 2133 all adopt existing technologies.

[0061] The feeding component 20 can place the materials at a low position in a proper orientation and convey them to the punching hole 111 at a high position. By controlling the length of the shifting rod 28, the shifting rod 28 can shift the materials at the same height as the conveying plate 26, but will not shift the materials at the same height as the moving channel 210. Therefore, the shifting rod 28 will not affect the conveyance of the materials to the transfer plate 22. The shifting rod 28 realizes linear movement on the moving top plate 27 through an electric push rod or the like, and the position of the moving top plate 27 is fixed above the conveyor chain group 21.

[0062] Embodiment 4

[0063] As Figure 10 and Figure 11 shown, on the basis of Embodiment 1, this embodiment provides a positioning component 30, and the positioning component 30 is used to limit the materials at the position of the punching hole 111.

[0064] There are multiple groups of positioning components 30. The positioning component 30 includes a base 31, a top rod 32, a second air cylinder 33, a lifting rod 34, a movable rod 35, a third spring 36, and a pressing plate 37. The base 31 is fixed on the turntable 13. One end of the movable rod 35 is rotatably connected to the base 31, and the other end is rotatably connected to the top rod 32. The top rod 32 is rotatably connected to the lifting rod 34 on the inner side of the connection position with the movable rod 35. The lifting rod 34 is rotatably connected to the base 31 below the connection position with the top rod 32. The second air cylinder 33 is fixed on the turntable 13, and its movable end is fixedly connected to one end of the top rod 32 away from the base 31. The top of the third spring 36 is fixed on the lifting rod 34, and the bottom is fixed on the pressing plate 37. The pressing plate 37 is arranged on one side of the punching hole 111. The above all use rotating shafts to achieve rotational connections.

[0065] In the non-working state, the pressing plate 37 abuts against the turntable 13. When the second air cylinder 33 extends, it drives one end of the top rod 32 to lift. Under the limiting cooperation of the base 31, the other end of the top rod 32 drives the movable rod 35 and the lifting rod 34 to rotate relative to the base 31, and the lifting rod 34 lifts upward, and the pressing plate 37 also lifts accordingly. When the materials enter above the punching hole 111 and abut against the side wall of the base 31, the second air cylinder 33 retracts, and the pressing plate 37 resets, and the pressing plate 37 presses the materials. When the materials follow the turntable 13 and rotate to below the punching unit 17, the pressing plate 37 lifts again to avoid the punching unit 17. The positioning component 30 prevents the materials from shaking during rotation.

[0066] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention.
