Description

Technical Field

[0001] The utility model relates to the technical field of hardware processing, in particular to a punching device for processing sheet-shaped hardware. Background Art

[0002] Hardware is usually made of metals such as steel, aluminum, and copper, and is made through processing and surface treatment processes. It is widely used in technical fields such as construction, machinery, and electronics. Sheet hardware processing mostly includes cutting and forming of sheet hardware. Forming can be done through stamping, bending or other forming processes.

[0003] Among them, when punching sheet hardware, the continuous long sheet hardware is automatically transported to the punching station, and the sheet hardware is punched by lowering the punching head. The waste generated after punching is easy to remain in the sheet hardware or get stuck in the hole head, which requires manual processing later, thereby affecting the punching efficiency of the entire sheet hardware. For this reason, we propose a punching device for sheet hardware processing to solve the above problems. Utility Model Content

[0026] The punching mechanism 4 includes a third frame 41, which is fixedly mounted on the top of the second frame 21. Lifting cylinders 42 are fixedly mounted on both sides of the third frame 41. A fourth frame 421 is fixedly mounted on the driving end of the lifting cylinder 42. A connecting pipe 43 is fixedly mounted in the middle of the fourth frame 421.

[0028] The bottom end of the positioning pressure shaft 45 extends out of the bottom end of the punching cutter head 44, and a punching base 31 used in conjunction with the punching cutter head 44 is movable on one side of the material placement table 3 near the connecting pipe 43. The long sheet hardware is stably transported on the material placement table 3. When the punching position of the long sheet hardware moves to the position of the punching cutter head 44, the lifting cylinder 42 is controlled to open and drive the fourth frame 421 to drive the connecting pipe 43, the positioning pressure shaft 45 and the punching cutter head 44 to move downward. The positioning pressure shaft 45 first contacts the punching position of the sheet hardware for positioning, and then continues to lower the connecting pipe 43, the positioning pressure shaft 45 and the punching cutter head 44. The shaft 45 and the punching cutter head 44, the third ring 471 squeezes the buffer spring 472 to contract, and the punching cutter head 44 descends through the sheet metal and is placed in the punching base 31, and the punching position of the sheet metal is automatically punched. After the punching is completed, the connecting tube 43, the positioning pressing shaft 45 and the punching cutter head 44 are moved upward, and the buffer spring 472 is reset to drive the positioning pressing shaft 45 to always press the punching position of the sheet metal, effectively preventing the waste generated by the punching from being stuck in the punching cutter head 44, so that the waste is retained in the punching position of the sheet metal, which is convenient for the subsequent use of the punching cutter head 44;

[0029] The external thread of the punching base 31 is installed with a connecting screw 32, and the top thread of the connecting screw 32 is installed at the bottom end of the material placement table 3, so that the punching base 31 can be easily disassembled and replaced by removing the connecting screw 32.

[0030] The auxiliary mechanism 5 includes an auxiliary transverse frame 51 and a guide slide shaft 52. The guide slide shaft 52 is fixedly mounted on one side end of the fourth frame 421. An adjustment slot 501 corresponding to the guide slide shaft 52 is opened on one side of the auxiliary transverse frame 51. The guide slide shaft 52 is slidably engaged in the adjustment slot 501. A material-removing longitudinal rod 53 is movably inserted into the end of the auxiliary transverse frame 51 away from the guide slide shaft 52. The guide slide shaft 52 slides in the adjustment slot 501 to adjust the distance between the material-removing longitudinal rod 53 and the punching head 44 to adapt to the distance between two adjacent hole positions.

[0031] The outer thread of the material return longitudinal rod 53 is installed with a first nut 54, and the upper surface of the first nut 54 contacts the lower surface of the auxiliary horizontal frame 51. The outer thread of the material return longitudinal rod 53 is installed with a second nut 541, and the lower surface of the second nut 541 contacts the upper surface of the auxiliary horizontal frame 51. The material return longitudinal rod 53 is fixed by using the first nut 54 and the second nut 541.

[0032] A fastening bolt 55 is threadedly installed on the top of one side of the auxiliary horizontal frame 51 close to the fourth frame 421. The end of the fastening bolt 55 extends into the adjustment slide groove 501. The end of the fastening bolt 55 contacts the upper surface of the guide slide shaft 52, and the fastening bolt 55 is used to fix the guide slide shaft 52.

After the punching position of the sheet hardware is automatically punched, the sheet hardware is continued to be transferred so that the next punching position is moved to the position of the punching head 44. At this time, the waste material moves to the material return slot 301, and the punching head 44 is lowered to continue punching. At the same time, the fourth frame 421 drives the auxiliary horizontal frame 51 and the material return longitudinal rod 53 to descend, and the material return longitudinal rod 53 assists in pressing the waste material, and the waste material automatically separates from the sheet hardware and falls into the material return frame 7 for automatic waste return, thereby improving the use effect of the entire punching device.

[0034] Working principle: When in use, according to the punching requirements, replace and install the appropriate punching head 44, punching base 31, and slide the guide slide 52 in the adjustment slide 501, adjust the distance between the material return longitudinal rod 53 and the punching head 44 to adapt to the distance between two adjacent holes, and fix the guide slide 52 by tightening the bolt 55;

[0035] The long sheet hardware is transported stably on the loading platform 3. When the punching position of the long sheet hardware moves to the position of the punching cutter head 44, the lifting cylinder 42 is controlled to open and drive the fourth frame 421 to drive the connecting pipe 43, the positioning pressure shaft 45 and the punching cutter head 44 to move downward. The positioning pressure shaft 45 first contacts the punching position of the sheet hardware for positioning, and then continues to descend the connecting pipe 43, the positioning pressure shaft 45 and the punching cutter head 44. The third ring 471 squeezes the buffer spring 472 to contract, and the punching cutter head 44 descends through the sheet hardware and is placed in the punching base 31 to automatically punch the punching position of the sheet hardware. After the punching is completed, the connecting pipe 43, the positioning pressure shaft 45 and the punching cutter head 44 are moved upward, and the buffer spring 472 is reset to drive the positioning pressure shaft 45 to always press the punching position of the sheet hardware, effectively preventing the waste generated by the punching from being stuck in the punching cutter head 44, so that the waste remains in the punching position of the sheet hardware.

[0036] After the punching position of the sheet hardware is automatically punched, the sheet hardware continues to be transported so that the next punching position is moved to the position of the punching head 44. At this time, the waste material moves to the material return groove 301, and the punching head 44 is lowered to continue punching. At the same time, the fourth frame 421 drives the auxiliary horizontal frame 51 and the material return longitudinal rod 53 to descend. The material return longitudinal rod 53 assists in pressing the waste material, and the waste material automatically separates from the sheet hardware and falls into the material return frame 7 for automatic waste return, thereby improving the use effect of the entire punching device.

[0037] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
