Problems solved by technology
When two times of punching are used, due to the repetition and conversion of positioning and the plastic deformation of the material in the second punching process, the width of the drive wheel ribs cannot be guaranteed to be consistent, especially in the two punchings, odd intervals The punching force of the transmission wheel of the magnetic groove cannot be symmetrical and balanced, resulting in the easy breakage of the die punch, the cost of a single die is increased, and two sets of dies are required to process this part

Embodiment Construction
[0019] The invention consists of two parts: an upper mold assembly and a lower mold assembly:
[0020] The upper die assembly consists of the following parts:
[0021] (1) As shown in Figure 1: The main structure of the upper mold assembly is composed of an upper template 1, an upper mold backing plate 2, an upper mold fixing plate 3 and a discharge plate 7. The upper die plate 1, the upper die backing plate 2 and the upper die fixing plate 3 are fixedly connected by screws 5. In order to ensure the clamping and guiding of the upper mold, a small guide post 12 and a small guide sleeve 13 are used for guiding and positioning between the upper mold backing plate 2, the upper mold fixing plate 3 and the discharge plate 7.
[0022] (2) As shown in Figure 1: The punching part of the upper die assembly is mainly composed of the upper die fixing plate 3, the outer punch 8 and the inner punch 9. As shown in Figure 3, the upper die fixing plate 3 is provided with a circle of outer grooves 3...

The invention relates to a once molding die of a vehicle air-conditioning clutch driving wheel, comprising an upper die assembly and a lower die assembly. The once molding die is characterized in that an upper die fixing plate in the upper die assembly is connected with a group of external punches and a group of inner punches; outer grooves (16a, 18a) corresponding to the external punches and inner grooves (16b, 18b) corresponding to the inner punches are arranged in a concave die (16) in the lower die assembly and a lower die backing plate (18). The periphery of the concave die (16) is provided with a concave die outer casing (17) to protect the concave die to be capable of bearing the simultaneous impact of the inner punches and the external punches. The once molding die has the advantages that the die is processed in one time molding during the punching processing; technical requirements of parts are guaranteed; the service life of the punches during the punching is improved by about 10 times; the efficiency is improved by nearly one time; and the processing cost is reduced.
Description
Technical field [0001] The invention relates to manufacturing equipment for automobile parts, in particular to a punching die for a clutch transmission wheel of an automobile air conditioner. Background technique [0002] The role of the transmission wheel in the clutch is to transmit power, and the size of the magnetic isolation groove and the accuracy of the shape and position tolerance directly affect the torque during power transmission. In the same industry in China, both the even-numbered magnetic isolation grooves and the odd-numbered magnetic isolation grooves of the transmission wheels are formed by two punching and the production efficiency is low. The punching and forming of the transmission magnetic isolation magnetic groove is a difficult part to process. Its characteristic is that the magnetic transmission groove is only 3mm wide, the bottom surface of the part is 5.2mm thick, and the structure of the inner and outer ring magnetic grooves is close to the inner and o...
