Description

Technical Field

[0001] The utility model relates to the technical field of hinge processing, in particular to a punching device used for hinge production. Background Art

[0002] A hinge, also known as a hinge, is a mechanical device used to connect two solids and allow them to rotate relative to each other. Hinges are widely used in our daily lives. For example, in the field of furniture, cabinet doors and wardrobe doors usually require hinges to open and close. High-quality hinges can ensure smooth opening and closing of doors, reduce noise, and be durable. Although hinges seem simple, they are an indispensable and important component in connection and rotation. During the production process, holes need to be punched out of hinges to facilitate bolt fixing.

[0003] The utility model with application number 202322696386.1 discloses a hinge stamping die. By setting a convenient replacement component, the stamping head can be replaced conveniently and quickly, thereby saving a lot of manpower and material resources. By setting a second connecting column and a spring, the component can be automatically reset, thereby achieving the effect of automatically clamping the stamping head. By setting a clamping block, the stamping head can be clamped and fixed. By setting a first connecting ring and a second connecting ring, the stamping head can be easily installed and disassembled during replacement. By setting a clamping groove, the clamping block can be perfectly clamped into the second connecting ring, thereby achieving The effect of fixing and preventing falling off is achieved by setting the support plate and the support block so that the two can be located at the same horizontal plane, which facilitates the interaction between the subsequent components and the materials on the support plate. By setting the second cylinder and the push plate, the steel can be automatically pushed away from the support plate after the stamping is completed, so as to prevent the subsequent processing from being affected. The problem that the existing hinge needs to be stamped by a stamping die during the production process is solved. Since the stamping die frequently contacts the hinge during operation, the stamping head will be worn and needs to be replaced regularly, which is time-consuming and labor-intensive.

[0004] However, the above-mentioned hinge stamping die lacks a limit clamp for the hinge during stamping, and manual assistance is needed to limit the hinge during stamping, which poses a safety hazard and is likely to cause the hinge to move. The above-mentioned hinge stamping die requires manual assistance to place the hinge on the support plate during stamping, and then remove it after the stamping is completed, which is likely to affect the stamping efficiency. The surface of the support plate in the above-mentioned hinge stamping die is flat, and the waste generated by stamping cannot be automatically removed, so that the surface of the support plate needs to be cleaned before each stamping. Therefore, the utility model proposes a punching device for hinge production to solve the problems existing in the prior art. Utility Model Content

A bracket 2 is fixed in the middle of the punching table 1, a cylinder 3 is fixed on the top of the bracket 2, a lifting platform 4 is fixed below the telescopic end of the cylinder 3, lifting slide rails 5 are symmetrically fixed on both sides of the bracket 2, sliders 6 are symmetrically fixed on both sides of the lifting platform 4, the sliders 6 slide in contact with the lifting slide rails 5 on both sides, and springs are symmetrically fixed below the lifting platform 4. 7. A limit plate 8 is fixedly provided at the lower end of the spring 7, a sliding feeding mechanism is provided on the punching table 1, a punch replacement mechanism is provided under the lifting table 4, and a feeding mechanism is provided at the lower middle part of the punching table 1. The cylinder 3 is supplied with air by an external air pump. When punching, the cylinder 3 extends to drive the lifting table 4 and the slider 6 to descend along the lifting rail 5. The limit plate 8 first contacts the feeding guide rail 10 and is clamped on both sides of the hinge for limiting. The spring 7 elastically makes the limit plate 8 stably clamped on both sides of the hinge. After the punching is completed, the cylinder 3 retracts to drive the limit plate 8 to rise to release the limit, thereby realizing the limit of the hinge by synchronous lifting and lowering with the punching action, and effectively preventing the hinge from displacement during the punching process.

[0020] The sliding feeding mechanism includes a supporting punching plate 9, a feeding guide rail 10, a feeding roller 11 and a motor 12. A supporting punching plate 9 is fixedly provided in the middle of the punching table 1, and a feeding guide rail 10 is fixedly provided on the supporting punching plate 9. A feeding roller 11 is rotatably provided on one side of the punching table 1. A motor 12 is fixedly provided at the rear of one side of the punching table 1. The output end of the motor 12 is drive-connected to the feeding roller 11. One side of the feeding guide rail 10 extends outward and tilts upward. The bottom of the feeding roller 11 is close to the feeding guide rail 10. A feeding mechanism is provided in the middle of the supporting punching plate 9. Before punching, the hinge is arranged and placed on the upward tilted side of the feeding guide rail 10 to facilitate sliding feeding of the hinge. When feeding, the motor 12 drives the feeding roller 11 to rotate, and the friction of the feeding roller 11 pushes the hinge to slide along the feeding guide rail 10 to feed.

[0021] The punch replacement mechanism includes a slide groove 13, a punch block 14, a through hole 15, a threaded hole 16 and a fixing bolt 17. A slide groove 13 is provided in the middle of the bottom of the lifting platform 4. A punch block 14 is slidably inserted along the slide groove 13 at the bottom of the lifting platform 4. Through holes 15 are symmetrically provided at the four corners of the punch block 14. Threaded holes 16 are symmetrically provided at the four corners of the bottom of the lifting platform 4.

[0023] The punching device for hinge production arranges the hinges and places them at an inclined position on one side of the feeding guide rail before punching. When loading, the motor starts to drive the feeding roller to rotate at intervals and rub against the hinge to realize feeding. When punching, the cylinder extends to drive the lifting platform and the slider to slide down along the lifting slide rail, so that the limit plate first contacts the feeding guide rail, and the hinge is clamped between the limit plates to prevent the hinge from displacement. As the lifting platform further descends, the hinge is punched by the punch block, and the waste generated by the punching automatically falls into the collection box through the discharge chute and the discharge pipe. At the same time, the spring is compressed to keep the limit plate clamped and limited. After the punching is completed, the cylinder retracts to drive the lifting platform to rise and drive the limit plate to rise to release the limit. The motor drives the feeding roller to rotate again and rub against the hinge to feed again, thereby realizing automatic feeding and punching. When the punching specifications need to be changed, the fixing bolts are screwed down, the punch block is pulled out along the slide groove for replacement, and the fixing bolts are screwed in again.
