This is a fine shell of rotary motor assembled on the image detection equipment of human digestive system. After receiving the inquiry drawings from customers, we set up a special team to carry out project approval and promotion,After understanding the customer's detailed demand information, from the mold design, to the mold material selection (Misumi standard parts, Japanese steel of the same grade), mold processing equipment (Seibu machine is mainly used for slow wire), mold assembly, mold debugging, punch (Aida machine imported from Japan), stamping, cleaning, packaging, etc., to ensure the qualification rate of each process, Especially in the tolerance of circular runout.To ensure that the parts can not only meet the needs of customers, but also exceed the expectations of customers in terms of tolerance, so as to facilitate assembly.
The shell of the steering motor has very high requirements for dynamic balance. The material thickness is 0.8mm, and there are four side punching holes, which are easy to deform. The ordinary forward die cannot meet the accuracy requirements of customers.
Considering the application and the accuracy requirements of the drawings, we used transmission die scheme with Japanese equipment AIDA, and 2D manipulator to meet the concentricity and coaxiality requirements during side punching, so as to ensure that the circular runout can meet the requirements of the customer during dynamic balance detection.
Strict Tolerance Requirement
The scheme of forward die, which is usually applied in the industry, is easy to deform the shell when processing the side punching, so the motor dynamic balance is abnormal when it rotates, and finally the whole motor is out of work. In the scheme of manipulator, our team discussed and simulated the process sequencing for many times, and passed the optimal process layout design to ensure the tolerance requirements of verticality and circular runout.
Control of stretch lines and burrs on cutting surface
The forming punch and die are made of tungsten steel. During the third drawing, we try our best to reduce the drawing lines and burrs and control them within the specified range. In the processing layout, we add shaping process. On the basis of ensuring the concentricity of the product, the generation of lines and burrs is strictly controlled.
After stamping, a layer of oil left on the surface of the product. How to realize the perfect cleaning treatment?
We install the product on the product rack, enter from the feeding port, carry out automatic cleaning and drying, and finally return to the packing port. The fully automatic ultrasonic carbon fiber cleaning equipment not only finished 100% cleaning efficiently, but also ensured zero-carbon emission and no environmental pollution
The finished parts and small module assemblies have been delivered. The assembled modules and parts will be fully tested for the small-scale trial production in next stage. This is an excellent project, in the overall test phase of the finished product, we are confident to achieve success. It is worth to mention that: small modules and parts testing have passed the one-time testing standard of our customer.
