Description

Technical Field

[0001] This utility model relates to the field of hardware parts processing technology, specifically to a pre-cutting device for manufacturing hinges for hardware parts. Background Technology

[0002] A hinge, also known as a hinge, is a mechanical device used to connect two solid objects and allow them to rotate relative to each other. It mainly serves to connect and rotate, enabling rotatable parts such as doors, windows, and cabinet doors to open and close smoothly. Before manufacturing a hinge, the hinge blades need to be punched. Currently, existing punching equipment is usually used to punch hinges.

The blanking punch includes: a punch holder with at least one mounting through hole and an assembly groove within the mounting through hole; and at least one punch component with an inclined protrusion at one end. The inclined protrusion extends obliquely from the farthest end of the punch component towards the other end and converges on the side wall of the punch component. Each punch component passes through a corresponding mounting through hole, and the inclined protrusion abuts against the assembly groove. Compared with existing technologies, this invention effectively avoids the problems of punch components loosening and breaking on the punch holder, prevents uneven force distribution caused by the protrusion during the pulling process, extends the service life of the punch component, and significantly improves production efficiency.

[0004] However, this device also has the following drawbacks:

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4 This utility model provides a technical solution:

[0026] A punching device for manufacturing hinges for hardware parts includes a processing table 1. A mounting groove 2 is provided on one side of the top surface of the processing table 1. A storage box 3 is fixedly installed in the middle of the top of the processing table 1. Two sets of limiting plates 12 are provided between the storage box 3 and the lower mold 7. The inner side of the limiting plate 12 is set as an inclined surface. The limiting plate 12 is fixedly connected to the processing table 1.

[0027] By setting up the storage box 3, multiple sets of material plates can be added at one time for automatic feeding by the feeding component. The material plates in the storage box 3 are automatically moved downward by gravity, which facilitates continuous feeding and improves processing efficiency. By setting up the limit plate 12, the material plates can be prevented from shifting during the feeding process, ensuring that the material plates smoothly enter the lower mold 7.

[0028] It also includes a feeding assembly, which includes a push plate 4. The middle of one side of the push plate 4 is fixedly connected to the telescopic end of the first electric telescopic rod 5. The push plate 4 is slidably engaged with the openings 6 on both sides of the bottom of the storage box 3. The first electric telescopic rod 5 is fixedly connected to the other side of the top surface of the processing table 1. Two sets of guide rods 13 are provided on both sides of the first electric telescopic rod 5. One end of the guide rod 13 is fixedly connected to both sides of one side of the push plate 4. The top of the guide rod 13 is flush with the top of the push plate 4. The guide rod 13 is slidably engaged with the fixing plate 14. The fixing plate 14 is fixedly installed on the top surface of the processing table 1.

[0029] By setting the first electric telescopic rod 5, the push plate 4 can be moved through the telescopic end of the first electric telescopic rod 5, thereby pushing the material plate into the lower mold 7, which improves processing efficiency, reduces labor costs, and replaces manual loading and unloading, thus avoiding safety accidents. By setting two sets of guide rods 13, the stability of the push plate 4 can be improved, preventing the push plate 4 from deviating. Furthermore, the top of the guide rod 13 is flush with the top of the push plate 4, which can prevent the push plate 4 from being stuck by the next material plate during the reset process.

[0030] It also includes a blanking assembly, which includes a lower die 7, which is installed in the mounting slot 2 by screws. An upper die 8 is provided directly above the lower die 7. The top center of the upper die 8 is fixedly connected to the telescopic end of the hydraulic cylinder 9. The hydraulic cylinder 9 is fixedly installed in the middle of the top surface of the top plate 15. The top plate 15 is fixedly connected to the processing table 1 by four sets of support columns 16. The upper die 8 slides with the support columns 16 around its perimeter.

[0031] The hydraulic cylinder 9 provides downward pressure, which, when used in conjunction with the upper die 8 and the lower die 7, enables the punching of the material sheet.

[0032] It also includes a feeding assembly, which includes a pusher frame 10. The top surface of the pusher frame 10 is set as an inclined surface. The pusher frame 10 and the surface of the lower mold 7 are provided with a sliding groove 11 for sliding cooperation. The bottom middle of the pusher frame 10 is fixedly connected to the telescopic end of the second electric telescopic rod 17. The bottom of the second electric telescopic rod 17 is fixedly installed on the mounting plate 18. The mounting plate 18 is fixedly connected to the support leg 19 at the bottom of the processing table 1.

[0033] By setting a second electric telescopic rod 17, the pusher frame 10 can be driven to move upward, thereby ejecting the material plate from the lower mold 7 after punching. The material plate can also slide to one side of the lower mold 7 via the inclined surface at the top of the pusher frame 10 to achieve automatic material discharge, which further improves processing efficiency and reduces labor costs.

[0034] In practical use, the device is moved to the designated position, and the material boards used to manufacture the hinges are stacked and placed in the storage box 3. During the punching operation, the first electric telescopic rod 5 is activated, and its telescopic end is extended. The telescopic end of the first electric telescopic rod 5 pushes the push plate 4 to move. The push plate 4 pushes out the bottom material board through the opening 6 at the bottom of the storage box 3, and moves into the lower mold 7 under the guidance of the two sets of limiting plates 12. When the material board is completely inside the lower mold 7, the first electric telescopic rod 5 is stopped from extending, and the hydraulic cylinder 9 is activated to control the hydraulic pressure. The telescopic end of cylinder 9 extends downward, and the telescopic end of hydraulic cylinder 9 pushes the upper mold 8 to move downward, cooperating with the lower mold 7 to punch out a circular hole of a specified size on the surface of the material plate. After punching, the upper mold 8 is reset by hydraulic cylinder 9, and the push plate 4 is reset by the first electric telescopic rod 5. Then the second electric telescopic rod 17 is started, and the telescopic end of the second electric telescopic rod 17 is controlled to drive the push frame 10 to move upward. The push frame 10 extends out from the slide groove 11, pushes the punched material plate upward, and slides out through the inclined surface at the top of the push frame 10 to achieve automatic material discharge.

[0035] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
