DETAILED DESCRIPTION

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figures 1 to 3 , in the embodiment of the present invention, a hardware punching device with high positioning accuracy includes:

[0032] A workbench 1 and a feeding groove 101 and a punching groove 102 arranged at the top of the workbench 1. The punching groove 102 is arranged at one end of the feeding groove 101 and extends through to one end of the outer wall of the workbench 1. A storage groove 103 is arranged inside the workbench 1 at the end of the feeding groove 101 away from the punching groove 102;

[0033] A discharge plate 2 arranged on the outer wall of the workbench 1 near one end of the feeding groove 101, and a first electric push rod 3 is installed at one end of the workbench 1 away from the discharge plate 2;

[0034] Support columns 4 fixed to the top of the workbench 1 and distributed outside the punching groove 102. The top of the support column 4 is provided with a top plate 5. A second electric push rod 6 is installed at the top of the top plate 5. The output end of the second electric push rod 6 penetrates below the top plate 5 and is connected with a punching seat 7;

[0035] A feeding mechanism 8 distributed inside the storage groove 103 and at the top of the workbench 1, which is used for automatically feeding the hardware raw materials and automatically discharging the raw materials after punching;

[0036] A limiting mechanism 9 distributed at both ends inside the punching groove 102 and extending through to the inside of the workbench 1, which is used for limiting the raw materials inside the punching groove 102.

[0037] In this embodiment: The hardware raw materials can be placed through the feeding groove 101. The hardware raw materials inside the feeding groove 101 can be pushed into the punching groove 102 through the feeding mechanism 8, and the raw materials after punching inside the punching groove 102 can be pushed to the discharge plate 2 for discharging operation. The raw materials entering the punching groove 102 can be limited through the limiting mechanism 9 to avoid displacement and limitation of the raw materials during the punching process. Then, the punching seat 7 can be driven to move downward through the second electric push rod 6 to punch the hardware raw materials.

[0038] Please pay special attention to Figures 1 to 3 , the feeding mechanism 8 includes:

[0039] Guide vertical rods 801 fixedly connected to the top of the workbench 1 and distributed outside the feeding groove 101;

[0040] The L-shaped push block 802 disposed inside the storage groove 103, and the output end of the first electric push rod 3 penetrates into the storage groove 103 and is connected to the L-shaped push block 802;

[0041] The linkage arm 803 located at the bottom end of the L-shaped push block 802 and extending through one end of the outer wall of the workbench 1. The top end of the linkage arm 803 is provided with a first extrusion block 804 and a second extrusion block 805. The second extrusion block 805 is located at the end of the linkage arm 803 away from the L-shaped push block 802, and the first extrusion block 804 is located at the end of the second extrusion block 805 close to the L-shaped push block 802;

[0042] A through groove extending through the feed groove 101 and the stamping groove 102 is provided inside the workbench 1. A punching head is provided at the bottom end of the stamping seat 7, and a punching groove matching the punching head is provided at the bottom end of the inner wall of the stamping groove 102.

[0043] In this embodiment: Before stamping the raw material of the hardware part, it is necessary to first place the raw material of the hardware part into the feed groove 101 along the trajectory of the guide vertical rod 801, and then stack the raw materials of the hardware part one by one. The guide vertical rod 801 can limit the raw material of the hardware part to keep it in a neat stacked state. When punching is required, the first electric push rod 3 can be started. The first electric push rod 3 can push the L-shaped push block 802 towards the feed groove 101. When the L-shaped push block 802 contacts the raw material inside the feed groove 101, the L-shaped push block 802 will push the bottommost raw material of the hardware part to move along the through groove into the stamping groove 102. During this process, the top end of the L-shaped push block 802 can support the upper raw material of the hardware part. After the raw material of the hardware part is pushed, the first electric push rod 3 runs in the reverse direction to drive the L-shaped push block 802 to automatically reset. When the L-shaped push block 802 is received into the storage groove 103, the upper raw material of the hardware part automatically falls into the feed groove 101, and then repeating this operation can realize the automatic feeding operation of the raw material of the hardware part, and the punched raw material can be pushed during the feeding process, so that the punched raw material is moved out along the discharge plate 2 for automatic discharging operation.

[0044] Please refer specifically to Figures 1 to 3 , the limiting mechanism 9 includes:

[0045] The first limiting block 901 disposed at one end of the inner wall of the stamping groove 102 close to the feed groove 101, and the bottom end of the first limiting block 901 extends through the inside of the workbench 1 and is in close contact with the top end of the first extrusion block 804;

[0046] The second limiting block 902 disposed at one end of the inner wall of the stamping groove 102 close to the discharge plate 2, and the bottom end of the second limiting block 902 extends through the inside of the workbench 1 and is in close contact with the top end of the second extrusion block 805;

[0047] The limiting slide block 903 is located inside the workbench 1 and fixedly connected to both ends of the outer walls of the first limiting block 901 and the second limiting block 902. An elevating chute matching the limiting slide block 903 is arranged inside the workbench 1.

[0048] In this embodiment: During the process of the first electric push rod 801 driving the L-shaped push block 802 for automatic feeding, the L-shaped push block 802 can drive the linkage arm 803 to move synchronously, and the linkage arm 803 can drive the first extrusion block 804 and the second extrusion block 805 to move synchronously. When the L-shaped push block 802 has not yet contacted the hardware raw material, the first extrusion block 804 and the second extrusion block 805 will first separate from the first limiting block 901 and the second limiting block 902 respectively. At this time, the first limiting block 901 and the second limiting block 902 will automatically move downward under their own gravity. When the L-shaped push block 802 enters the feeding groove 101 and contacts the hardware, the tops of the first limiting block 901 and the second limiting block 902 are flush with the bottom end of the inner wall of the stamping groove 102. When the L-shaped push block 802 continues to move and pushes the hardware raw material into the stamping groove 102, this hardware raw material will push the raw material completed in the stamping groove 102 into the discharging plate 2. At the same time, the first extrusion block 804 will be driven to approach the second limiting block 902. When there is still a certain distance between the unpunched hardware raw material and the second limiting block 902, the first extrusion block 804 first contacts the second limiting block 902 and squeezes the second limiting block 902 to move upward. The second limiting block 902 will jack up the tail end of the punched hardware raw material, so that the punched hardware raw material can fall onto the blanking plate 2 faster. Finally, the L-shaped push block 802 will push the unpunched hardware raw material to closely fit with the second limiting block 902. At this time, the feeding and discharging of the hardware raw material are completed. Then, the first electric push rod 3 runs in the reverse direction to drive the L-shaped push block to automatically reset. During this process, the first extrusion block 804 will first separate from the second limiting block 902, and then contact the first limiting block 901 and squeeze the first limiting block 901 to move upward, while the second extrusion block 805 resets and contacts the second limiting block 902 to squeeze it to move upward. Finally, the first limiting block 901 and the second limiting block 902 can limit both ends of the hardware raw material, thus avoiding the phenomenon of the hardware raw material shifting during the punching process.

[0049] Please refer with emphasis to Figure 1 , the number of the material guiding vertical rods 801 is set to be multiple. The distribution tracks of the multiple material guiding vertical rods 801 match the inner wall of the feeding groove 101 and also match the outer wall of the hardware.

[0050] In this embodiment: Multiple material guiding vertical rods 801 facilitate the falling of the raw materials of the hardware parts into the feeding groove 101, and the raw materials of the hardware parts can be neatly stacked through the material guiding vertical rods 801, so that multiple raw materials of the hardware parts can be placed at one time, effectively improving the working efficiency.

[0051] Please refer specifically to Figures 2 to 3 , the bottom ends of the first limiting block 901 and the second limiting block 902 are of a hemispherical structure, both ends of the first extrusion block 804 are of an inclined surface structure, one end of the second extrusion block 805 close to the linkage arm 803 is of an inclined surface structure, and a set of linkage arms 803, first extrusion blocks 804, and second extrusion blocks 805 are arranged on both sides of the L-shaped push block 802. A chute matching the linkage arm 803, the first extrusion block 804, and the second extrusion block 805 is arranged inside the workbench 1.

[0052] In this embodiment: By the contact between the inclined surfaces of the first extrusion block 804 and the second extrusion block 805 and the spherical surfaces of the first limiting block 901 and the second limiting block 902, it is convenient to push the first limiting block 901 and the second limiting block 902 to move upward. By arranging two sets of linkage arms 803, first extrusion blocks 804, and second extrusion blocks 805, the up and down movement of the first limiting block 901 and the second limiting block 902 can be made more stable.

[0053] Please refer specifically to Figures 2 to 3 , there is a spacing between one end of the top of the L-shaped push block 802 far from the first electric push rod 3 and the feeding groove 101, and a horizontal plane structure is arranged at the top of both the first extrusion block 804 and the second extrusion block 805.

[0054] In this embodiment: With this structure, when the hardware parts pushed by the L-shaped push block 802 have not contacted the second limiting block 902, the first extrusion block 804 can contact the second limiting block 902 one step earlier, and the second limiting block 902 is kept in a jacked-up state through the horizontal plane structure at the top of the first extrusion block 804, so that the second limiting block 902 limits the hardware parts. After the L-shaped push block 802 is reset, the first limiting block 901 and the second limiting block 902 can be kept in a stable jacked-up state through the horizontal plane structures at the tops of the first extrusion block 804 and the second extrusion block 805.

[0055] The above-mentioned is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.
