Technical Field


The contact finger of the composite watchband is a key component in high-voltage SF6 products. The shape of the part is complex and the precision is high. At the beginning of the production of high-pressure SF6 products in Xichang, the belt contact refers to imported from Japan. The technical difficulty of strip contact processing is to process a set of multi-process composite progressive stamping die and design a set of advanced technology and process. Reasonable multi-process composite progressive fine stamping die is the key to solve the problem.


Utility model content


The purpose of the utility model is to provide a multi-process composite progressive fine-blanking die with advanced technology, reasonable process and meeting the requirements of processing qualified watchband touch fingers.


The composite watchband touch finger overcomes the shortcomings of the prior art and provides a wrist-band finger punching die, which includes a die handle, an upper seat, a lower seat, an upper die and a lower die. The mold handle is arranged above the upper seat and fixedly connected with the upper seat. The bottom of the upper seat is provided with a ball guide post, and the bottom of the ball is provided with a lower seat. The lower mold is fixed at the position of the upper surface of the lower seat relative to the mold handle, and the surface of the lower mold is provided with two guide A plates; There is a boss above the guide plate, and the boss is fixed under the lower mold through a small guide post.


The die shank is formed by connecting the die shank joint, the movable die shank and the spherical spacer.


Detailed method


The mold of the contact finger of the composite watchband includes an upper seat, a guide post and a guide sleeve, a mold handle, an upper mold, a lower mold and a lower seat. Elastic unloading is used for unloading, and the elastic unloading plate is installed on the upper die. When stamping, the elastic discharge plate is always pressed against the sheet, and the stamping parts are relatively flat. The mold handle uses a floating mold handle, which is connected by a mold handle joint, a movable mold handle and a spherical gasket. The pressure of the press is transmitted vertically to the upper die. The guide device is a gapless guide device with high precision and long service life, and is suitable for stamping work of blanking dies. The ball accuracy is IT5, and the balls are arranged symmetrically and evenly, forming an angle of 5 ° with the center line, so that each ball has its own raceway when moving. The secondary is guided by a small guide post. The small guide column is made of Crl2, the outer diameter is less than 2.12, the tolerance is (0,-0.008), and the guide plate H6/f6 is matched. The third stage is guided by the punch and guide plate, and the punch and guide plate match H6/f6.
