[0002] In modern industrial production, blanking and punching of parts are key processes in metal processing, machinery manufacturing, and automotive parts production, directly affecting product precision, production efficiency, and manufacturing costs. They are widely used in the processing of raw materials such as sheet metal and profiles.

[0003] In existing technologies, the conventional process for punching parts is as follows: first, the part to be processed is placed on the lower punching die, and then the hydraulic mechanism drives the punching head to apply downward pressure, thereby completing the punching operation of the part. The traditional processing method has some drawbacks: the lower punching die and the punching head are both fixed. When it is necessary to punch parts with different diameters, the punching slot of the lower punching die and the punching head cannot be adjusted according to the actual needs to switch to the corresponding diameter. As a result, the equipment can only complete the punching operation of a single specification and is difficult to adapt to the processing needs of punching multiple diameters. Utility Model Content

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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] Please refer to Figure 1 As shown, a part blanking punching adjustment mechanism includes a punching worktable 1, a support frame 2 fixedly installed on the upper end of the punching worktable 1, a fixed crossbeam plate 3 fixedly connected to the upper end of the support frame 2, a hydraulic mechanism 4 fixedly installed on one end of the fixed crossbeam plate 3, a punching head adjustment component 5 for switching punching heads of different diameters is provided at the lower end of the hydraulic mechanism 4, and a punching die adjustment component 6 for switching die holes of different diameters is provided below the punching head adjustment component 5.

[0018] In a specific embodiment, the hydraulic mechanism 4 serves as a power source, providing the pressure required for punching. When the equipment is started, the hydraulic mechanism 4 can drive the punch head adjustment component 5 below to move downwards, completing the punching operation on the workpiece through impact force. The operator can pre-adjust and lock the punch head of the corresponding diameter to the working position according to the hole diameter requirements of the part to be processed. When the hydraulic mechanism 4 is started, only the punch head in the working position will move downwards with the hydraulic power to complete the punching action. The punching die adjustment component 6 located directly below the punch head adjustment component 5 has a die hole cavity inside that corresponds one-to-one with the diameter of the punch head. After the punch head adjustment component 5 completes the diameter switching, the operator needs to adjust the punching die adjustment component 6 simultaneously to move the die hole of the corresponding diameter directly below the punch head, forming a coaxial alignment state of "punch head - workpiece die hole".

[0019] Please refer to Figures 1 to 3 As shown, as a technical optimization of this utility model, the punch head adjustment assembly 5 includes an upper template 51. A fastener 41 is fixedly installed on the upper end of the upper template 51. The upper end of the fastener 41 is fixedly installed on the lower end of the hydraulic mechanism 4. A guide groove 55 is opened inside the upper template 51. A guide rod 56 is slidably connected inside the guide groove 55. A connecting plate 57 is fixedly connected to one side of each of the two guide rods 56. A punch head body 54 of different diameters is fixedly connected to the lower end of the connecting plate 57. An electric push rod 53 is fixedly installed on one end of the connecting plate 57. The electric push rod 53 is fixedly installed on one side of the U-shaped bracket 52. One end of the U-shaped bracket 52 is fixedly installed at both ends of the upper template 51.

[0020] In a specific embodiment, when punching holes of different diameters is required for the part, the electric push rod 53 extends and retracts, driving the connecting plate 57 and the punch head body 54 to move synchronously. The guide rod 56 slides in the guide groove 55 to ensure that the punch head body 54 maintains a stable movement trajectory during the adjustment process. By switching punch head bodies 54 of different diameters, the punching processing requirements of different hole diameters can be met.

[0021] Please refer to Figures 1 to 4As shown, as a technical optimization of this utility model, the punching die adjustment assembly 6 includes a lower template 61 and a parts placement frame 66. The lower end of the parts placement frame 66 is fixedly installed on the upper end of the punching workbench 1. Track rods 62 are fixedly sleeved at both ends inside the parts placement frame 66. Sliding grooves 63 are opened inside the two track rods 62. Mounting plates 610 are fixedly connected to the opposite sides of the two track rods 62. Sliding rods 68 are slidably connected inside the sliding grooves 63 of the two track rods 62. The opposite sides of the two sliding rods 68 are fixedly connected to the two ends of the lower template 61. A lead screw 69 is rotatably sleeved inside the sliding groove 63 of one of the track rods 62. The lead screw 69 is rotatably connected inside the sliding rod 68. A micro motor 64 is fixedly installed at one end of the lead screw 69. A fixing plate 65 is fixedly installed at one end of the micro motor 64. The output shaft of the micro motor 64 is connected to one end of the lead screw 69.

[0022] Furthermore, the lower template 61 has punching slots 67 of different diameters at its center. Above the punching slots 67 of different diameters, there are connecting plates 57 of different diameters. The lower template 61 is slidably fitted inside the part placement frame 66, and the punching slots 67 of different diameters of the lower template 61 are exposed at the middle end of the part placement frame 66, corresponding to the lower part of the punching head body 54 of different diameters.

[0023] In a specific embodiment, when different punching slots 67 can be aligned with different punching head bodies 54, the diameter of the required punching slot 67 is determined according to the hole diameter requirements of the part to be processed. The micro motor 64 is started, and the output shaft of the motor drives the lead screw 69 to rotate. The lead screw 69 pushes the sliding rod 68 to slide along the sliding groove 63 through the thread transmission. The lower template 61 moves synchronously with the sliding rod 68. During the movement, the track rod 62 and the sliding groove 63 limit the offset of the lower template 61 to ensure its horizontal and stable movement. When the lower template 61 moves to the target position, the punching slot 67 of the corresponding diameter is just exposed in the middle working position of the part placement frame 66, that is, directly below the punching head, so as to realize the adjustment and switching of different punching slots 67. The part to be processed is placed in the part placement frame 66, so that its punching position is aligned with the exposed punching slot 67. The upper hydraulic mechanism 4 is started to drive the punching head of the corresponding diameter to move down, pass through the part and enter the punching slot 67 to complete the punching operation.

[0024] In use, when punching parts requiring holes of different diameters, the electric push rod 53 extends and retracts, causing the connecting plate 57 and the punch head body 54 to move synchronously. The guide rod 56 slides within the guide groove 55, ensuring the punch head body 54 maintains a stable movement trajectory during adjustment. By switching between punch head bodies 54 of different diameters, different punch head bodies 54 can be adjusted and switched. When different punching slots 67 can be aligned with different punch head bodies 54, the required diameter of the punching slot 67 is determined according to the hole diameter requirements of the part to be processed. The micro motor 64 is then started, and the motor output shaft drives the lead screw 69 to rotate. The lead screw 69 pushes the part through the threaded transmission. The sliding rod 68 slides along the sliding groove 63, and the lower template 61 moves synchronously with the sliding rod 68. During the movement, the track rod 62 and the sliding groove 63 limit the offset of the lower template 61 to ensure its horizontal and stable movement. When the lower template 61 moves to the target position, the punching groove 67 of the corresponding diameter is exposed in the middle working position of the part placement frame 66, that is, directly below the punching head, so as to realize the adjustment and switching of different punching grooves 67. The part to be processed is placed in the part placement frame 66, and its punching position is aligned with the exposed punching groove 67. The upper hydraulic mechanism 4 is activated to drive the punching head of the corresponding diameter downward, pass through the part and enter the punching groove 67 to complete the punching operation.
