Description

Technical Field

[0001] This utility model relates to the field of punching technology for hardware parts, and more specifically, to a hardware processing punching device that is easy to adjust. Background Technology

[0002] Hardware refers to traditional hardware products, also known as "small hardware," which are made of five metals: gold, silver, copper, iron, and tin. These metals can be processed into works of art such as knives and swords, or into metal components. In modern society, hardware is much more extensive, including hardware tools, hardware parts, daily-use hardware, building hardware, and security products. Small hardware products are mostly not final consumer goods. When processing hardware products, punching is usually required for practical use, which necessitates the use of a punching machine.

[0003] Common metal processing punching equipment can only perform punching operations on metal products, but it lacks the function of conveniently adjusting the punching hole diameter. When punching metal products, punching heads are required to perform punching. However, punching heads are usually fixed with multiple bolts. When facing different hole diameter processing requirements, all bolts must be removed before a punching head that matches the required hole diameter can be reinstalled, which ultimately leads to a very cumbersome process for changing the punching head.

[0004] In summary, to facilitate the replacement of punch heads, it is necessary to solve the problem of cumbersome punch head disassembly and assembly procedures, so that punch heads can be easily replaced according to actual processing needs without the need for multiple bolts for fixation. Utility Model Content

[0005] The hardware processing punching device provided by this utility model solves the problem that punching cutters are usually fixed with multiple bolts. When facing processing requirements of different hole diameters, all bolts have to be removed, which affects the convenience of cutting head replacement.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a conveniently adjustable metal processing punching device, comprising a control housing, a lifting cylinder fixedly connected inside the control housing, a lifting rod slidably connected inside the lifting cylinder, a recovery frame fixedly connected to the outside of the lifting rod, a horizontal groove on the front side of the recovery frame, a vertical groove on the outside of the lifting rod, a first magnetic block fixedly connected to the bottom end of the lifting rod, multiple sliders slidably connected inside both the horizontal and vertical grooves, a shaped connecting rod fixedly connected to the front side of the sliders, a telescopic rod fixedly connected to the end of the shaped connecting rod away from the sliders, a punching head fixedly connected to the end of the telescopic rod away from the shaped connecting rod, a second magnetic block fixedly connected to the top of the punching head, the second magnetic block located below the lifting rod and at the top of the punching head being magnetically attracted to the first magnetic block, a lifting mechanism provided on the control housing for controlling the lifting movement of the punching head, and a support mechanism provided on the control housing for supporting the entire device and the metal products.

[0007] In a preferred embodiment, the lifting mechanism includes a drive assembly and a reset assembly, wherein the drive assembly controls the downward movement of the lifting rod, and the reset assembly controls the upward movement of the lifting rod.

[0008] In a preferred embodiment, the drive assembly includes a motor fixedly connected inside the control housing and an eccentric wheel fixedly connected to the output end of the motor.

[0009] In a preferred embodiment, the reset assembly includes a drive rod fixedly connected to the top of the lifting rod, a reset spring fixedly connected to the bottom of the drive rod, and a roller rotatably connected to the top of the drive rod.

[0010] In a preferred embodiment, the support mechanism includes a main frame assembly and a hardware placement assembly, wherein the main frame assembly is used to support the entire device and the hardware placement assembly is used to support the hardware.

[0011] In a preferred embodiment, the main frame assembly includes a support housing fixedly connected to the left side of the control housing, a support base plate fixedly connected to the bottom of the support housing, and four support legs fixedly connected to the bottom of the support base plate.

[0012] In a preferred embodiment, the hardware product placement assembly includes a pad disposed on the top of a support base plate and a discharge groove formed on the top of the pad.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention significantly improves the convenience and efficiency of punch hole diameter adjustment through an innovative sliding groove linkage design and magnetic fixing mechanism. Its sliding groove structure guides the slider and punch head to complete precise directional displacement. Combined with the transmission of the irregularly shaped connecting rod, the positioning process of punch heads of different sizes is smooth and intuitive, completely eliminating the cumbersome steps of disassembly, alignment, and tightening commonly found in traditional replacement methods. The magnetic adsorption design of the first and second magnetic blocks achieves a firm, self-fixing mechanism the moment the punch head is in place, requiring no manual locking. This not only greatly shortens replacement time and effectively avoids the risk of loosening during operation but also significantly reduces the probability of errors, ultimately achieving a fast, accurate, stable, and reliable convenient adjustment function for the punch hole diameter.

[0021] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] Refer to the instruction manual appendix Figures 1 to 5A conveniently adjustable metal punching device includes a control housing 1. A lifting cylinder 11 is fixedly connected inside the control housing 1. A lifting rod 12 is slidably connected inside the lifting cylinder 11. A retrieval frame 13 is fixedly connected to the outside of the lifting rod 12. A horizontal groove 14 is provided on the front side of the retrieval frame 13. A vertical groove 15 is provided on the outside of the lifting rod 12. A first magnetic block 16 is fixedly connected to the bottom end of the lifting rod 12. Multiple sliders 17 are slidably connected inside both the horizontal groove 14 and the vertical groove 15. A shaped connecting rod is fixedly connected to the front side of each slider 17. 18. A telescopic rod 19 is fixedly connected to the end of the irregular connecting rod 18 away from the slider 17. A punch head 20 is fixedly connected to the end of the telescopic rod 19 away from the irregular connecting rod 18. A second magnetic block 21 is fixedly connected to the top of the punch head 20. The second magnetic block 21 located below the lifting rod 12 and the top of the punch head 20 is magnetically attracted to the first magnetic block 16. A lifting mechanism is provided on the control housing 1. The lifting mechanism is used to control the lifting movement of the punch head 20. A support mechanism is provided on the control housing 1. The support mechanism is used to support the entire device and hardware products.

[0023] It should be noted that the multiple punch heads 20 have different sizes, but the multiple second magnetic blocks 21 have the same size as the first magnetic block 16, and the extension lengths of the multiple telescopic rods 19 are also different.

[0024] Refer to the instruction manual appendix Figures 1 to 4 The lifting mechanism includes a drive assembly and a reset assembly. The drive assembly controls the downward movement of the lifting rod 12, and the reset assembly controls the upward movement of the lifting rod 12.

[0025] It should be noted that by having the roller 323 contact the eccentric wheel 312, the lateral thrust of the eccentric wheel 312 is reduced, so that the drive rod 321 only receives the downward thrust.

[0026] Refer to the instruction manual appendix Figure 3 The drive assembly includes a motor 311 fixedly connected inside the control housing 1 and an eccentric wheel 312 fixedly connected to the output end of the motor 311.

[0027] It should be noted that the eccentric wheel 312 is driven to rotate by the motor 311, and the eccentric wheel 312 will come into contact with the roller 323 during the rotation process.

[0028] Refer to the instruction manual appendix Figure 4 The reset assembly includes a drive rod 321 fixedly connected to the top of the lifting rod 12, a reset spring 322 fixedly connected to the bottom of the drive rod 321, and a roller 323 rotatably connected to the top of the drive rod 321.

[0029] It should be noted that when the eccentric wheel 312 is not in contact with the roller 323, the lifting rod 12 loses its downward pressure. At this time, the lifting rod 12 is pushed up and down by the thrust of the return spring 322, and the lifting rod 12 drives the punch head 20 to move upward in sync until the punch head 20 is reset.

[0030] Refer to the instruction manual appendix Figures 1 to 2 The support mechanism includes a main frame assembly and a hardware product placement assembly. The main frame assembly is used to support the entire device, and the hardware product placement assembly is used to support the hardware products.

[0031] It should be noted that a slot is provided on the support base plate 412 at the position corresponding to the discharge trough 422, which facilitates the discharge of waste materials.

[0032] Refer to the instruction manual appendix Figure 1 The main frame assembly includes a support housing 411 fixedly connected to the left side of the control housing 1, a support base plate 412 fixedly connected to the bottom of the support housing 411, and four support legs 413 fixedly connected to the bottom of the support base plate 412.

[0033] It should be noted that the support base plate 412 is supported by four support legs 413, so that the support base plate 412 is a certain distance from the ground, so that the downward discharge of waste will not be obstructed.

[0034] Refer to the instruction manual appendix Figure 1 The hardware product placement assembly includes a pad 421 disposed on the top of the support base plate 412 and a discharge groove 422 opened on the top of the pad 421.

[0035] It should be noted that when the hardware product is placed on the pad 421, the punch head 20 will press the hardware product as it moves downward.

[0036] Working principle: First, place the hardware product on the pad 421. Then, select the appropriate punch head 20 according to the required hole diameter. After selection, push all the sliders 17 to slide in the horizontal slide groove 14 until the slider 17 connected to the appropriate punch head 20 is above the vertical slide groove 15. At this time, pull down the appropriate punch head 20. The appropriate punch head 20 drives the slider 17 to slide from the horizontal slide groove 14 to the inside of the vertical slide groove 15 through the special-shaped connecting rod 18 until the appropriate punch head 20 is below the lifting rod 12. Then, pull the appropriate punch head 20 towards the lifting rod 12. At this time, the appropriate punch head 20 drives the telescopic rod 19 to extend until the appropriate punch head 20 is above the vertical slide groove 15. Position 0 is below the first magnetic block 16. At this time, the matching punch head 20 is magnetically attracted to the first magnetic block 16 through the second magnetic block 21, thereby fixing the matching punch head 20. Then, the motor 311 drives the eccentric wheel 312 to rotate. During the rotation, the eccentric wheel 312 will contact the roller 323. The contact between the roller 323 and the eccentric wheel 312 reduces the side thrust of the eccentric wheel 312, so that the drive rod 321 only receives the downward thrust. The drive rod 321 drives the matching punch head 20 to move downward through the lifting rod 12 until the matching punch head 20 punches the hardware product. The punched waste is discharged downward through the discharge chute 422.

[0037] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
