本文主要从球坯成型方面进行某些技术探讨。在自动冷镦机方面要提高其生产效率首先要在切料系统下功夫,特别是要寻找一种新的热处理方法来制造曲线板,提高其高速时的耐磨性;其次采用集中强度润滑系统和良好的润滑油过滤装置;停车是否可靠也是解决高速冷镦机的效率的一个重要方面。在提高冷镦球坯质量方面,认为有必要改进冲头滑块导轨面的设计,增加或加固切料刀杆在切料位置的支承导轨,改变切料曲线板的运动方向,改进切料胎固紧方式等。在冲球模(压球胎)方面,应采用新材料,如钢结硬质合金,大球模采用锒压组合冲模,并应提高冲模的加工精度。
This article mainly from the ball blank forming some technical discussions. In the automatic cold heading machine to improve its production efficiency, we must first work in the cutting system, in particular, to find a new method of heat treatment to create curved plate to improve its wear resistance at high speed; followed by intensive lubrication system And a good oil filter device; parking is reliable and also solve the high-speed cold heading machine efficiency is an important aspect. In improving the quality of the cold heading blank, it is considered necessary to improve the design of the punch slider guide surface, increase or reinforce the support guide of the cutter arbor in the cutting position, change the movement direction of the cut curve board, Fastening methods. In the red ball mold (ball pressure), should adopt new materials, such as steel hard alloy, large ball mold using pressure combination die, and should improve the processing accuracy of the die.
