    Diameter reduction machine product introduction

    The body adopts low-carbon steel and is welded into a C-shaped structure. It has good oil temperature and heat dissipation and is easy to handle. It is suitable for assembly line or unitized production. It is specially developed by Tianyu Machinery for automobile rubber shock absorber manufacturers. It has low power consumption and production. High efficiency, the product placement surface has a high-precision mechanical dead limit scale adjustment plate with 0.005MM as the unit, which makes the product diameter adjustable and does not affect the diameter of the reduced diameter product due to equipment or mold wear, and makes the mold larger The manufacturing is simple and the cost is greatly reduced. Its excellent performance has become a leader in the automotive rubber shock absorber industry at home and abroad. The equipment adopts a proportional relief valve and a pressure sensor, combined with a PLC programmable controller to form a closed-loop control system, so that the reduction force does not vary with temperature and voltage. The influence of material rigidity.

    Production process
    1. Rough machining with a lathe first, with a margin of 1MM.
    2. Heat treatment to HRC60-62.
    3. Finish machining on lathe, reserve 0.3MM margin.
    4. Finish machining to the required size on the internal and external cylindrical grinder.
    5. Laser print the product drawing number, and the arrangement number of 12 pieces.
    6. The thread is cut into 12 pieces, not all of which can be cut, set aside 0.5MM, and you can cut them all.
    7. Deburring.
    8. Material: CR12 CR12MOV.
