DETAILED DESCRIPTION

[0027] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0028] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 8The figure is a structural diagram of a stamping equipment for hinge production provided by an embodiment of the present invention, comprising a workbench 1, wherein two groups of relatively distributed vertical plates 2 are fixedly installed on the surface of the workbench 1, a bearing plate 4 is slidably installed along the vertical direction between the two groups of vertical plates 2, a cylinder 3 is fixedly installed on the top ends of the two groups of vertical plates 2, the telescopic end of the cylinder 3 is connected to the bearing plate 4, a plurality of stamping columns 41 are arranged on the bottom wall of the bearing plate 4, a horizontal column 5 located below the bearing plate 4 is rotatably installed between the two groups of vertical plates 2, a bearing column 6 is fixedly installed on the surface of the horizontal column 5, the vertical cross-section of the bearing column 6 is a polygonal structure, a plurality of groups of placement grooves 61 distributed at equal intervals are provided on the surface of the bearing column 6, a stamping groove 62 cooperating with the stamping column 41 is provided on the bottom wall of the placement groove 61 into the bearing column 6, a positioning mechanism 8 cooperating with the horizontal column 5 is arranged between the two groups of vertical plates 2, and the positioning mechanism 8 includes a rotating component 81. The anti-inertia component 82 and the rotating component 81 are located on the bottom wall of the supporting plate 4 and are connected to the cross column 5. When the supporting plate 4 moves in the vertical direction, the rotating component 81 is used to control the cross column 5 and the supporting column 6 to rotate synchronously by a certain angle. The anti-inertia component 82 is located at the end of the supporting column 6. The anti-inertia component 82 controls the supporting column 6 and the cross column 5 to rotate precisely by a certain angle by cooperating with the rotating component 81. A clamping mechanism 7 that cooperates with the placement slot 61 is provided in the supporting plate 4. The clamping mechanism 7 includes an adsorption component 71 and a unloading component 72. The adsorption component 71 is located in the placement slot 61. The adsorption component 71 is used to fix the hinge to be stamped in the placement slot 61. The unloading component 72 is located in the supporting column 6 and is connected to the adsorption component 71. The unloading component 72 is used to remove the stamped hinge in the placement slot 61 by cooperating with the adsorption component 71.

[0030] Initially, the anti-inertia component 82 positions the cross column 5 and the load-bearing column 6. When stamping a batch of hinges, the hinge is placed in the placement groove 61 on the surface of the load-bearing column 6. The adsorption component 71 can conveniently fix the hinge in the placement groove 61. After the position of the hinge is fixed, the cylinder 3 pushes the load-bearing plate 4 to move vertically downward so that the bottom wall of the load-bearing plate 4 and the surface of the load-bearing column 6 fit each other. At this time, the stamping column 41 and the stamping groove 62 cooperate with each other, and the hinge in the placement groove 61 can be conveniently stamped. After the hinge in the placement slot 61 at the top of the support column 6 is stamped, the cylinder 3 pulls the support plate 4 to move vertically upward. While the support plate 4 moves upward, the rotating assembly 81 cooperates with the anti-inertia assembly 82 to control the cross column 5 and the support column 6 to rotate along their own axis by a certain angle, thereby causing another group of placement slots 61 on the surface of the support column 6 to rotate to the highest position. At this time, the hinge in the placement slot 61 at the highest position rotates to be distributed relative to the support plate 4. The cylinder 3 pushes the support plate 4 downward again, and the hinge on the surface of the support column 6 can be stamped again. After multiple cycles, the support column 6 rotates multiple times, thereby driving the stamped hinge to rotate synchronously. When the stamped hinge rotates to the lowest position on the surface of the support column 6, the unloading assembly 72 can automatically remove the stamped hinge from the placement slot 61, and a storage box is placed on the surface of the workbench 1. The hinge that falls off the surface of the support column 6 can automatically fall into the storage box.

[0031] like Figure 2 , Figure 3 , Figure 4 , Figure 7 As shown, as a preferred embodiment of the present invention, the rotating assembly 81 includes a fixed tooth ring 811 fixedly installed on the surface of the cross column 5, a slide groove 812 is opened at the end of the supporting plate 4, a sliding block 813 is slidably installed in the slide groove 812, a vertical rod 814 is fixedly installed on the bottom wall of the sliding block 813, a rack 815 is fixedly installed on the side wall of the vertical rod 814, the rack 815 is meshed with the fixed tooth ring 811, and the sliding block 813 is connected to a guide part 9. When the supporting plate 4 drives the sliding block 813 to move in the vertical direction, the guide part 9 controls the sliding block 813 to move synchronously in the slide groove 812.

[0032] When in use, the cylinder 3 pushes the carrier plate 4 to move downward, and the carrier plate 4 drives the vertical rod 814 and the rack 815 to move downward synchronously. When the carrier plate 4 moves downward, the guide portion 9 positions the sliding block 813 in the slide groove 812. At this time, the rack 815 does not contact the fixed gear ring 811 when it moves downward. After the stamping is completed, the cylinder 3 pulls the carrier plate 4 to move upward, and the carrier plate 4 drives the vertical rod 814 and the rack 815 to move upward synchronously. When the carrier plate 4 moves upward, the guide portion 9 positions the sliding block 813 in the slide groove 812. At this time, the rack 815 does not contact the fixed gear ring 811 when it moves downward. Part 9 adjusts the position of the sliding block 813 in the sliding groove 812. At this time, the rack 815 will contact the fixed gear ring 811 when moving upward. The rack 815 and the fixed gear ring 811 are meshed and transmitted, which can drive the cross column 5 and the bearing column 6 to rotate. After the rack 815 is separated from the fixed gear ring 811, the anti-inertia component 82 positions the bearing column 6. At this time, the cross column 5 and the bearing column 6 can stop rotating in time. At this time, another group of placement grooves 61 on the surface of the bearing column 6 are distributed relative to the bearing plate 4.

[0033] like Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, as a preferred embodiment of the present invention, the guide portion 9 includes a guide groove 92 opened on the side wall of the vertical plate 2, and the side wall of the sliding block 813 is provided with a guide column 91 slidably connected to the guide groove 92, and the guide groove 92 is composed of a left vertical groove 921, a right vertical groove 922, a bottom connecting groove 923 and a top connecting groove 924. The left vertical groove 921, the top connecting groove 924, the right vertical groove 922 and the bottom connecting groove 923 are connected in sequence to form an annular structure, and the top end of the left vertical groove 921 and the bottom end of the right vertical groove 922 are respectively provided with limit blocks 925 that cooperate with the guide column 91, and the sliding block 813 is provided with an adjustment portion 10 connected to the guide column 91.

[0034] When the supporting plate 4 is at the highest point, the guide column 91 is at the highest point of the top connecting groove 924. When the supporting plate 4 moves downward, the guide column 91 moves along the top connecting groove 924 and further into the right vertical groove 922. The guide column 91 and the right vertical groove 922 cooperate with each other to position the sliding block 813 in the sliding groove 812. At this time, the vertical rod 814 and the rack 815 will not contact the fixed gear ring 811 when moving downward. When the supporting plate 4 moves to the lowest point, the guide column 91 moves to the lowest point of the bottom connecting groove 923. After the stamping is completed, the supporting plate 4 moves upward. At this time, the guide column 91 moves along the bottom connecting groove 923 and further moves into the left vertical groove 921. The guide column 91 and the left vertical groove 921 cooperate with each other, and the position of the sliding block 813 can be synchronously adjusted in the slide groove 912. At this time, when the vertical rod 814 drives the rack 815 to move upward, the rack 815 will engage with the fixed gear ring 811. The meshing transmission of the rack 815 and the fixed gear ring 811 can drive the horizontal column 5 and the supporting column 6 to rotate between the two sets of vertical plates 2.

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, as a preferred embodiment of the present invention, the adjusting portion 10 includes a telescopic hole 101 opened on the side wall of the sliding block 813, the guide column 91 is slidably installed in the telescopic hole 101, and a control spring 102 connected to the guide column 91 is fixedly installed in the telescopic hole 101.

[0036] When the guide column 91 moves from the top of the left vertical slot 921 to the top connecting slot 924 and when the guide column 91 moves from the bottom of the right vertical slot 922 to the bottom connecting slot 923, the limit block 925 squeezes the guide column 91, and the telescopic hole 101 cooperates with the control spring 102 to conveniently adjust the position of the guide column 91.

[0037] like Figure 3 , Figure 7 , Fig.10 As shown, as a preferred embodiment of the present invention, the anti-inertia component 82 includes a plurality of groups of magnetic positioning blocks 821 fixedly installed on the side wall of the supporting column 6 and distributed in a ring shape with equal intervals, and a plurality of groups of magnetic positioning plates 822 cooperating with the magnetic blocks 821 are fixedly installed on the side wall of the vertical plate 2.

[0038] When the cross column 5 and the supporting column 6 remain stationary, the magnetic positioning block 821 and the magnetic positioning plate 822 are fitted together to form a whole. When the rack 815 and the fixed gear ring 811 are meshed for transmission, the cross column 5 drives the supporting column 6 to rotate. At this time, the magnetic positioning block 821 and the magnetic positioning plate 822 are separated from each other. After the rack 815 and the fixed gear ring 811 are separated, multiple groups of magnetic positioning blocks 821 are again fitted with multiple groups of magnetic positioning plates 822 to form a whole. The magnetic positioning blocks 821 and the magnetic positioning plates 822 cooperate with each other to effectively prevent the supporting column 6 from rotating too much, so that the highest placement groove 61 of the supporting column 6 is relatively distributed with the supporting plate 4.

[0039] like Figure 1 , Figure 7 , Figure 8 , Fig. 9 As shown, as a preferred embodiment of the present invention, the adsorption component 71 includes vertical holes 711 respectively opened at both ends of the placement groove 61, and a compression spring 712 is fixedly installed in the vertical hole 711, and a magnetic block 713 extending to the outside of the vertical hole 711 is fixedly installed at the telescopic end of the compression spring 712, and the magnetic block 713 is slidably connected to the vertical hole 711.

[0040] The extrusion spring 712 applies a thrust to the magnetic block 713, and the magnetic block 713 extends into the placement slot 61, and the hinge is placed in the placement slot 61. The two groups of magnetic blocks 713 adsorb and fix the hinge in the placement slot 61 through magnetic attraction, and the bearing column 6 drives the hinge to rotate synchronously. When the hinge rotates to the highest position, the bearing plate 4 drives the stamping column 41 to move downward, and the hinge can be stamped conveniently. When the placement slot 61 on the surface of the bearing column 6 rotates to the lowest position, the unloading assembly 72 controls the magnetic block 713 to move into the vertical hole 711. At this time, the hinge is separated from the magnetic block 713 under the action of gravity, and the hinge falls freely.

[0041] like Figure 1 , Figure 7 , Figure 8 , Fig. 9 As shown, as a preferred embodiment of the present invention, the unloading assembly 72 includes a counterweight block 721 placed in a vertical hole 711 and sleeved in a compression spring 712, a through hole 722 is opened in the middle of the counterweight block 721, and a guide wheel 723 is rotatably installed at one end of the vertical hole 711 away from the magnetic block 713, and a pulling rope 724 is fixedly installed at one end of the magnetic block 713 facing the vertical hole 711, and the end of the pulling rope 724 away from the magnetic block 713 passes through the through hole 722 and the guide wheel 723 and is connected to the counterweight block 721.

[0042] When the placement slot 61 rotates to the lowest point of the supporting column 6, the counterweight block 721 moves downward in the vertical hole 711 under the action of gravity, and the counterweight block 721 and the pulling rope 724 cooperate with each other to pull the magnetic block 713 toward the vertical hole 711. At this time, the hinge is separated from the magnetic block 713 under the action of gravity, and the hinge falls freely.

[0043] The working principle of the present invention is: initially, the magnetic positioning block 821 and the magnetic positioning sheet 822 are attached to each other to form a whole, and the horizontal column 5 and the bearing column 6 remain stationary. The hinge is placed in the placement slot 61, and the two groups of magnetic blocks 713 adsorb and fix the hinge in the placement slot 61 through magnetic attraction. After the position of the hinge is fixed, the cylinder 3 pushes the bearing plate 4 to move vertically downward so that the bottom wall of the bearing plate 4 and the surface of the bearing column 6 fit each other. At this time, the stamping column 41 cooperates with the stamping slot 62, and the hinge in the placement slot 61 can be stamped conveniently. When the bearing plate 4 moves downward, the guide column 91 moves along the top connecting groove 924 and further into the right vertical groove 922. The guide column 91 cooperates with the right vertical groove 922 to locate the position of the sliding block 813 in the slide groove 812. At this time, the vertical rod 814 and the rack 815 will not contact the fixed gear ring 811 when moving downward. When the supporting plate 4 moves to the lowest point, the guide column 91 moves to the lowest point of the bottom connecting groove 923. After the stamping is completed, the supporting plate 4 moves upward. At this time, the guide column 91 moves along the bottom connecting groove 923 and further moves into the left vertical groove 921. The guide column 91 cooperates with the left vertical groove 921 to synchronously adjust the position of the sliding block 813 in the slide groove 912. At this time, when the vertical rod 814 drives the rack 815 to move upward, the rack 815 will engage with the fixed gear ring 811. The gear ring 815 engages with the fixed gear ring 811 to drive the horizontal column 5 and the supporting column 6 to rotate a certain angle between the two groups of vertical plates 2, thereby making the other group of placement grooves 61 on the surface of the supporting column 6 rotate to the highest position. At this time, the hinge in the highest position placement groove 61 rotates to be relatively distributed with the supporting plate 4, and the cylinder 3 pushes the supporting plate 4 to move downward again, and the hinge on the surface of the supporting column 6 can be stamped again. The bearing column 6 rotates multiple times in a reciprocating cycle, thereby driving the stamped hinge to rotate synchronously.

[0044] When the hinge after stamping rotates to the lowest position on the surface of the bearing column 6, the counterweight block 721 moves downward in the vertical hole 711 under the action of gravity, and the counterweight block 721 and the pulling rope 724 cooperate with each other to pull the magnetic block 713 toward the vertical hole 711. At this time, the hinge is separated from the magnetic block 713 under the action of gravity, and the hinge falls freely.

[0045] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
