DETAILED DESCRIPTION

[0036] In order to make the technical problems, technical solutions and beneficial effects solved by the invention more clearly understood, the invention is further described below in conjunction with the accompanying drawings and embodiments.

[0037] Example 1

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

[0040] The turntable 13 is rotatably arranged above the chassis 12, and a rotating shaft 110 is fixed under the turntable 13. The rotating shaft 110 is sleeved in the sleeve 18, and the rotating shaft 110 is driven by the first driving source. The turntable 13 is provided with a plurality of punching holes 111 equidistantly distributed around the circumference, and the aperture of the punching holes 111 gradually increases from top to bottom, and the drop hole 19 is arranged below the punching hole 111. The height of the turntable 13 and the chassis 12 relative to the frame 11 is fixed, and in particular, the positions of the rotating shaft 110 and the first driving source are fixed, and can be fixed by a fixing frame or the like. The first driving source is a motor, and the motor drives the rotating shaft 110 to rotate, and the rotating shaft 110 drives the turntable 13 to rotate, and the punching holes 111 on the turntable 13 also rotate accordingly. The punching unit 17 cooperates with the punching holes 111 distributed around the circumference to work in an intermittent manner, and the working efficiency is higher.

[0041] A punching unit 17 is provided above a punching hole 111. When the turntable 13 rotates, it is ensured that the punching unit 17 is always facing a punching hole 111. Figure 6 The punching unit 17 includes a hydraulic cylinder 171, a lifting block 172, a central wedge block 173 and two side pressure 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 pressure blocks 174. The top of the first spring 175 is fixed on the lifting block 172. The first spring 175 is compressible between the side pressure blocks 174 and the lifting block 172. The inner side walls of the two side pressure blocks 174 contact the outer wall of the central wedge block 173. The other outer walls of the two side pressure blocks 174 can contact the hole wall of the punching hole 111. The side walls of the side pressure blocks 174 and the central wedge block 173 contact each other in sequence. The first inclined wall 1741, the shoulder wall 1742 and the second inclined wall 1743 are connected, the first inclined wall 1741 and the second inclined wall 1743 have the same slope and are inclined toward the center line of the central wedge block 173, the shoulder wall 1742 is inclined in the direction away from the center line of the central wedge block 173, the central wedge block 173 includes an upper conical block 1731 and a lower conical block 1732 of an integral structure, the outer wall of the upper conical block 1731 abuts against the first inclined wall 1741, the outer wall of the lower conical block 1732 abuts against the shoulder wall 1742 and the second inclined wall 1743, the side pressure block 174 moves along the outer wall of the central wedge block 173, and in a natural state, the bottom wall height of the central wedge block 173 is greater than the bottom wall height of the two side pressure blocks 174.

[0042] The material to be punched can be rectangular or cross-shaped. The material is placed on the punching hole 111, and the turntable 13 is rotated to move the material to the bottom of the punching unit 17. The hydraulic cylinder 171 drives the lifting block 172 to move down quickly. Since the bottom wall height of the central wedge block 173 is greater than the bottom wall height of the two side pressure blocks 174, the two side pressure blocks 174 first contact the material and press the material into the punching hole 111. The two side pressure blocks 174 drive the material to contact the bottom plate 12 first, and the lifting block 172 continues to press down. The first spring 175 is compressed, the central wedge block 173 continues to move down, and the lower conical block 1732 slides downward along the second inclined wall 1743, and the lower conical block 1732 squeezes the two side pressure blocks 174 outward, and the two side pressure blocks 174 move outward. When the central wedge block 173 contacts the chassis 12, the other outer walls of the two side pressure blocks 174 contact or almost contact the hole wall of the punching hole 111. At this time, the material is punched into a hardware in the shape of the punching hole 111. The hydraulic cylinder 171 drives the lifting block 172 to move upward, and the punching is completed. The turntable 13 drives the hardware to continue to rotate. When the hardware rotates to the drop hole 19, the hardware falls from the drop hole 19 and is collected by the collection component.

[0043] The punching unit 17 includes a second spring 176, the two ends of which are respectively fixed on the two side pressure 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 pressure block 174 always contacts 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 pressure block 174 are relatively displaced, the side pressure block 174 can always move along the first inclined wall 1741 and the second inclined wall 1743.

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

[0045] refer to Figure 3 The surface of the chassis 12 is provided with a plurality of platform support areas 121, and the heights of the plurality of platform support areas 121 are different. The platform support areas 121 of different heights are rotated to be directly below the stamping unit 17 to achieve fine adjustment of the distance between the chassis 12 and the turntable 13, and to achieve fine adjustment of the top and bottom diameters of the hardware. Each platform support area 121 is provided with a drop hole 19 to ensure that the stamping and dropping are completed at the same height.

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

[0047] The collecting assembly includes a collecting box, and the hardware dropped out of the drop hole 19 directly drops into the collecting box. Of course, the collecting assembly may also include a collecting pipe, and the hardware dropped out of the drop hole 19 drops into the collecting pipe and finally drops into the collecting box.

[0048] Example 2

[0049] like Figures 1 to 6 As shown, on the basis of Example 1, this embodiment provides a stamping unit 17, and a plurality of rounded movable blocks 116 are provided at the bottom of the stamping hole 111. The rounded movable blocks 116 are fixed to the bottom of the turntable 13 by torsion springs 117, and the bottoms of the two side pressure blocks 174 are provided with rounded structures 118 that match the shape of the rounded movable blocks 116. When there is no force, the rounded movable blocks 116 will not contact the chassis 12. When the rounded movable blocks 116 are squeezed by the central wedge block 173 and the two side pressure blocks 174, the bottom of the rounded movable blocks 116 will resist the chassis 12.

[0050] During stamping, the bottom of the side pressure block 174 drives the material to squeeze the rounded corner movable block 116, and the bottom of the rounded corner movable block 116 contacts 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 block 116 will not contact the chassis 12, ensuring the normal rotation of the turntable 13.

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

[0052] Example 3

[0053] like Figures 7 to 9 As shown, based on Example 1, this embodiment provides a feeding assembly 20, which is used to transport the material to the position of the punching hole 111.

[0054] The loading assembly 20 includes two parallel conveyor chain groups 21, on which a plurality of equidistant conveyor plates 22 are fixed. The conveyor plates 22 on the two conveyor chain groups 21 are aligned for up and down conveying, and the material is conveyed up and down between the two conveyor plates 22 of equal height. A first conveyor frame 23 is provided on one side of the two conveyor chain groups 21, on which a linear moving module 24 is provided, on which a movable conveying bracket 25 is provided, on which a conveying plate 26 of the same height as a group of conveyor plates 22 is provided, and on which a turntable 13 is provided the same height, and on which a first pushing assembly for pushing the material from the conveying plate 26 to the punching hole 111 is provided.

[0055] The loading assembly 20 includes a lever 28 , which is disposed between the conveying plates 22 of the two conveying chain groups 21 . The lever 28 is movable and is used to push the material on the conveying plates 22 onto the conveying plate 26 .

[0056] A second conveying frame 29 is provided on the other side of the two conveying chain groups 21, and a moving channel 210 is opened between the second conveying frames 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, and the second pushing component 213 is used to push the material on the moving channel 210 to the conveying plate 22.

[0057] The second pushing assembly 213 includes a fixed frame 2131, a linear moving member 2132, a lifting member 2133 and a pushing block 2134. The fixed frame 2131 is fixed in position, the linear moving member 2132 is fixed on the fixed frame 2131, the lifting member 2133 is vertically fixed on the movable end of the linear moving member 2132, and 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 bracket 25 and also completes pushing by horizontal movement and vertical movement.

[0059] The material is transported from the conveyor belt 212. When it is transported to the moving channel 210, one side of the material is pressed against the limit plate 211, the direction of the material is corrected, and the pushing block 2134 on the second pushing assembly 213 moves up and extends out of the moving channel 210, and pushes the material to between the two conveyor chain groups 21. The material is placed between two conveyor plates 22 of equal height. The two conveyor chain groups 21 drive the material to move up. When it moves up to the same height as the conveyor plate 26, the lever 28 pushes the material to the conveyor plate 26. The conveyor plate 26 moves through the linear moving module 24, approaches the turntable 13, and is then pushed to the punching hole 111 by the first pushing assembly.

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

[0061] The loading assembly 20 can straighten the material at a low position and transport it to the punching hole 111 at a high position. By controlling the length of the lever 28, the lever 28 can move the material at the same height as the conveying plate 26, but will not move the material at the same height as the moving channel 210. Therefore, the lever 28 will not affect the material transportation to the conveying plate 22. The lever 28 can achieve linear movement on the movable top plate 27 through an electric push rod, etc., and the position of the movable top plate 27 is fixed above the conveying chain group 21.

[0062] Example 4

[0063] like Fig.10 and Fig.11 As shown, based on the embodiment 1, this embodiment provides a positioning assembly 30, and the positioning assembly 30 is used to limit the material to the position of the punching hole 111.

[0064] There are multiple groups of positioning components 30, which include a base 31, a push rod 32, a second cylinder 33, a lifting rod 34, a movable rod 35, a third spring 36 and a pressure 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 push rod 32. The push rod 32 is rotatably connected to the lifting rod 34 on the inner side of the connection position with the movable rod 35, and the lifting rod 34 is rotatably connected to the base 31 below the connection position with the push rod 32. The second cylinder 33 is fixed on the turntable 13, and its movable end is fixedly connected to one end of the push 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 pressure plate 37. The pressure plate 37 is arranged on one side of the punching hole 111. The above all use a rotating shaft to achieve rotational connection.

[0065] When the material enters the punching hole 111 and presses against the side wall of the base 31, the second cylinder 33 retracts and the pressing plate 37 is reset. The pressing plate 37 presses the material. When the material follows the turntable 13 to the bottom of the punching unit 17, the pressing plate 37 is lifted again to avoid the punching unit 17. The positioning assembly 30 prevents the material from shaking during rotation.

[0066] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall fall within the protection scope of the present invention.
