Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts production, in particular to a punching die for an automobile air-conditioning pulley. Background Art

[0002] Automobile air-conditioning pulley punching refers to the mechanical stamping process on the air-conditioning compressor drive pulley in the automobile air-conditioning system to form holes of specific diameter and position.

[0003] When punching holes in existing automobile air-conditioning pulleys, the pulleys are usually placed manually so that they are located in the center of the punching die. However, manual adjustment has low precision and high labor intensity, and workers operate in the stamping area for a long time, which poses certain safety hazards.

[0004] Therefore, an automobile air-conditioning pulley punching die has been developed which can easily center the pulley and improve the punching accuracy of the pulley. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art in the above-mentioned background technology, the purpose of the utility model is to provide an automobile air-conditioning pulley punching die which can conveniently center the pulley and improve the punching accuracy of the pulley.

[0006] The technical solution is: a punching die for an automobile air-conditioning pulley, comprising a base, a twist handle, a bidirectional screw, a sliding seat, a central push wheel, a punching die, a hydraulic cylinder, a punching head and a clamping device. The inner middle part of the base is rotatably connected to a bidirectional screw, the front side of the bidirectional screw is connected to a twist handle, the front and rear parts of the bidirectional screw are both threadedly connected to a sliding seat, the sliding seats are both slidably connected to the base, the upper sides of the left and right parts of the sliding seat are rotatably connected to a central push wheel, the upper middle part of the base is slidably connected to a punching die, the top of the base is connected to a hydraulic cylinder, the telescopic end of the hydraulic cylinder is connected to a punching head, and clamping devices are provided on the upper sides of the left and right parts of the base.

[0007] As a further preferred solution, the twist handle is provided with anti-slip grooves.

[0008] As a further preferred embodiment, the clamping device includes a torsion head, a clamping ball, a ball joint, a middle connecting rod and a middle spring. The upper sides of the left and right parts of the base are rotatably connected to the torsion head, the upper parts of the torsion heads are rotatably connected to the clamping balls, the tops of the torsion heads are rotatably connected to the ball joints, the middle connecting rods are connected between adjacent ball joints, and the middle springs are connected between the rear torsion heads. Under the tension of the middle springs, the rear torsion heads will protect the layers from the downward pressure, and cooperate with the ball joints and the middle connecting pipe to synchronously control all the torsion heads to press the pulleys onto the base.

[0009] As a further preferred solution, the twisting head is a square distribution structure.

[0010] As a further preferred scheme, it also includes a unloading mechanism, which includes a material rack, a fixed motor and a cam. The material rack is connected to the upper middle side of the base, and multiple fixed motors are connected to the lower sides of the left and right parts of the perforating mold. Cams are connected to the output shafts of the fixed motors, and the cams are squeezed and matched with the material rack. The rotation of the fixed motor output shaft drives the cam to rotate, and the cam rotates to the protruding position to squeeze the material rack so that the perforating mold moves upward, thereby increasing the distance between the perforating mold and the material rack, which is convenient for the material dropped by punching.

[0011] As a further preferred solution, both the left and right parts of the material rack are inclined structures.

[0012] The beneficial effect is that the utility model drives the bidirectional screw to rotate by rotating the twist handle, and the bidirectional screw rotates to control the sliding seats to approach each other. The sliding seats approach each other and use the center push wheel to push the pulley to the center position, which can facilitate the centering of the pulley and improve the punching accuracy of the pulley.
