[0002] Hinges are mechanical devices used to connect two solid objects and allow relative rotation between them. They are commonly used in doors and windows to facilitate opening and closing. During the manufacturing process of hinges, a punching device is required to punch holes in them.

[0003] When punching hinges of different sizes, workers often need to change the upper and lower dies simultaneously to perform the corresponding punching operation, which increases the time spent changing dies and reduces the processing efficiency of the punching operation. Therefore, in view of this, we have studied and improved the existing structure and its shortcomings to provide a punching equipment for hinge processing, in order to achieve a more practical purpose.

[0021] Example:

[0022] As attached Figure 1 To be continued Figure 5 As shown: This utility model provides a punching device for hinge processing, including a base 1. The base 1 has sliding grooves on both sides of its interior. A sliding plate 2 is slidably connected inside the sliding grooves. A support frame 3 is fixedly installed at the top of the base 1. An electric push cylinder 4 is fixedly installed at the top of the support frame 3. The output end of the electric push cylinder 4 extends through to the bottom of the support frame 3 and is mounted on a fixing plate 5. A punching head 6 is installed at the bottom of the fixing plate 5. Guide grooves are provided on both sides of the sliding plate 2. A clamp 7 is slidably connected between the two sets of guide grooves. A lower mold 8 is connected inside the two sets of clamps 7. Electric push cylinders 9 are fixedly installed on both sides of the sliding plate 2. The output ends of the two sets of electric push cylinders 9 extend through to the interior of the sliding plate 2 and are fixedly connected to the clamps 7.

[0023] Each of the slide grooves is equipped with a lead screw 10, and each lead screw 10 is equipped with a ball nut on its outer side. A slider 11 that can slide and connect with the slide groove is fixedly installed on the outer side of the ball nut. The slider 11 is fixedly connected to one side of the sliding plate 2, which facilitates the horizontal movement of the sliding plate 2 and provides convenience for subsequent punching operations.

[0024] One end of each of the two sets of lead screws 10 passes through a slide groove and a synchronous pulley is fixedly installed on the outside of the base 1. The two sets of synchronous pulleys are connected by a synchronous belt 12. A drive motor 13 is fixedly connected to one side of the base 1. The drive motor 13 is connected to one of the sets of synchronous pulleys for transmission, so as to provide power to the equipment and achieve precise movement.

[0025] The mounting plate 14 is installed on the outer side of the fixing plate 5. The outer side of the mounting plate 14 has four sets of through holes. The pressure rods 15 are slidably connected inside the through holes. The bottom ends of the four sets of pressure rods 15 are fixedly installed with abutment plates 16. The center of the abutment plate 16 has a guide hole, and the punching head 6 is slidably connected to the guide hole. The outer side of the pressure rods 15 is fitted with springs 17. The two ends of the springs 17 are respectively abutted against the abutment plates 16 and the mounting plate 14. Limiting rings 18 are fixedly installed on the outer side of both sets of pressure rods 15. The limiting rings 18 are in contact with the top end of the mounting plate 14. This allows the abutment plates 16 to stably press the workpiece during punching, thereby ensuring the punching quality.

[0026] The lower mold 8 has slots on both sides, and the sliding plate 2 has symmetrically arranged locking plates 19 inside, which engage with the slots to fix the lower mold 8 and improve the stability of the lower mold 8.

[0027] Both sides of the two sets of clamps 7 are provided with through holes, and optical shafts 20 are slidably connected inside the through holes. The two ends of the optical shafts 20 are respectively fixedly connected to the inner sidewall of the sliding plate 2, which facilitates the movement of the clamps 7 and prevents them from deviating during movement, thereby affecting subsequent use.

[0028] The sliding plate 2 has a through groove on one side of its bottom end, and a waste bin 21 is connected inside the through groove. A handle 22 is fixedly installed on one side of the waste bin 21 to facilitate the centralized collection of waste after punching, thereby improving the ease of use of the device.

[0029] The working principle of this embodiment: When using the punching equipment, firstly, the electric pusher cylinder 29 is activated. The electric pusher cylinder 29 pushes the clamp 7 to move towards the center and clamps and fixes the lower mold 8. Then, the hinge is placed inside the lower mold 8. Next, the drive motor 13 is activated, which drives the synchronous belt 12 and the synchronous pulley connected to the synchronous belt 12 to rotate, thereby causing the lead screw 10 fixedly connected to the synchronous pulley to rotate, which in turn drives the sliding plate 2 to move horizontally. At the same time, the electric pusher cylinder 14 is activated, which drives the fixed plate 5 at its bottom end to move down, so that the punching head 6 punches the hinge. When the hinge is punched, the lower mold 8 can be pressed and limited by the cooperation of the spring 17 and the abutment plate 16, reducing the stress deformation around the cut or the hinge as a whole caused by punching. The waste material after punching will fall into the waste bin 21 for centralized collection, which is convenient to operate.
