How does a precision lathe stamp spring thimble parts?

time:2020-11-27 Views:283

  The spring thimble is a spring-type probe made of three basic parts of needle shaft, spring and needle tube after being riveted and preloaded by precision instruments. It has a precision spring structure inside. The outer coating of the spring thimble is usually gold-plated, which can better improve its anti-corrosion function, mechanical performance, electrical performance, etc. The needle tip has sharp needles, grasping needles, round needles, knife needles, etc. Spring thimble is usually used in mobile phones, communications, automobiles, medical, aerospace and other electronic products to make precision connections, which can improve the corrosion resistance, stability and durability of these connectors. Because the spring thimble is a very fine probe, it can be used in precision connectors to reduce the weight of the connector and the volume of the appearance, which can make the connector more refined and beautiful.

How does a precision lathe stamp spring thimble parts?(图1)

  The spring thimble connector will be sent for electroplating immediately after stamping. At this stage, some problems similar to the stamping stage, such as twisting, chipping or deformation of the pins, will also occur when the stamped pins are sent to the electroplating equipment, and the spring thimble with the above problems will be eliminated. So, how does a precision lathe stamp spring thimble parts?

  1. Stamping of lathe:

  The manufacture of spring thimble connectors usually starts with stamping. After a large-scale high-speed punching machine, the spring thimble connector is stamped with a thin metal strip. One end of the large coiled metal belt is fed into the front end of the punching machine, and the other end is wound into the reeling wheel through the hydraulic worktable of the punching machine. During this process, some finished products will have quality problems, such as scratches, curling, etc. Such finished products will be eliminated.

  2. Finished product test:

  Manufacturers of spring thimble connectors hope that the inspection system can detect various defects such as very small scratches and pinholes on the plating appearance of the connector pins. Even if these defects are easily identifiable for other products, because most of the spring thimble connectors are irregular and have angled appearance design, it is difficult for the visual inspection system to obtain enough images to identify these subtle defects. After the needle and needle tube of the spring thimble are processed by a lathe, after passing the quality inspection, there is no knife mark or scratching problem, and the product is electroplated according to the customer's needs. We will also advise the customer on the thickness of the metal layer according to the customer's application. .
