Side punching die for compressor motor shell

Abstract

The invention discloses a side punching die for a compressor motor shell. The side punching die comprises an upper seat plate, a lower seat plate, a shaping female die, an upper fixing plate arranged on the upper seat plate, and an upsetting inclined sliding block, an elbow joint pressure sliding block, a side punch sliding block which are arranged on the upper fixing plate, a plane lubricating base and a sliding rail base arranged on the lower seat plate, an upsetting sliding block which is arranged on the plane lubricating base and is pushed by the upsetting inclined sliding block to do linear motion, a side surface punching sliding block which is arranged in the sliding rail base and pushed by the side punch sliding block to do linear motion, a guiding device which is arranged on the lower seat plate and used for guiding the shaping female die, and a forming stress block which is arranged on the lower seat plate and used for limiting a product, a side surface punching male die is arranged on the side surface punching sliding block, and a pier-shaped male die is arranged on the upsetting sliding block. According to the side punching die for the compressor motor shell, the stability and reliability of product manufacturing can be improved, and the punching quality of the compressor motor shell is improved.

Description

technical field [0001] The invention belongs to the technical field of moulds, and in particular, the invention relates to a punching die for the casing side of a compressor motor. Background technique [0002] The current compressor motor casing is completed by multi-step stretching, rotary cutting and side punching, because the compressor motor casing is an elliptical full-curved part, after multi-step stretching, the compressor motor casing The step at the mouth is an elliptical curved surface, and the mouth is uneven, so it is impossible to effectively confirm that the plane to be used meets the requirements. After rotary cutting, the end surface is flat, and it is confirmed that the shape and size of the elliptical curved surface meet the requirements. , but in the side punching pier leveling process, due to the influence of the compressor motor casing by a very large side impact force and punching force, the size of the mating surface of the elliptical curved surface v...

Problems solved by technology

[0002] The current compressor motor casing is completed by multi-step stretching, rotary cutting and side punching, because the compressor motor casing is an elliptical full-curved part, after multi-step stretching, the compressor motor casing The step at the mouth is an elliptical curved surface, and the mouth is uneven, so it is impossible to effectively confirm that the plane to be used meets the requirements. After rotary cutting, the end surface is flat, and it is confirmed that the shape and size of the elliptical curved surface meet the requirements. , but in the side punching pier leveling process, because the compressor motor casing is affected by a very large side impact force and punching force, the size of the mating surface of the elliptical curved surface varies, which cannot meet the size and fit requirements

[0003] No matter how the previous stretching process is adjusted, the rotary cutting process cannot meet the accuracy guarantee of the ellipse assembly size. The side punching tooling is also continuously improved, improving the force of the pressing material, the sequence of the slider action, and the adhesion of the die surface. Both cannot meet the size requirements of the ellipse assembly surface

[0004] Therefore, the existing process cannot guarantee the size of the elliptical surface of the compressor motor casing in the side punching process, which leads to a very high number of defective products in the stamping process, and in the subsequent assembly process of the automated production line, the mating parts cannot be effectively matched. , leading to welding problems and scrapping the entire motor assembly, resulting in irreparable major economic losses and delivery delays
