Types and Basic Parameters
This standard specifies the types and basic parameters of radial forging machines. J/9955.1—1999
2B362(03—87
This standard is applicable to radial forging machines (hereinafter referred to as radial forging machines) for round and square sections or non-ferrous metal forging. The types of radial forging machines are divided into vertical and horizontal types. 3 Basic static sensitivity
3.1 The main number of radial forging machines is the maximum diameter of the workpiece. 3.2 The basic integer of the vertical radial forging machine shall comply with the provisions of Table 1. Table 1 Number of vertical radial forging machines
Forgeable Maximum diameter
Maximum length
Maximum impact force of each slow head
Number of head impacts per minute
Diameter adjustment
Times/min
1When making hollow replacement parts, the length shall be specified by the order form to the manufacturer. 0
4(or 3)
2The maximum size of the pipe is called the maximum size of the pipe: if the slow-made alloy steel and other high-strength metal materials, the maximum size of the door silver should be reduced by 15% compared with the value listed in the table
The basic parameters of the horizontal forging machine shall comply with the requirements of Table 2. 3.3 Basic parameters of horizontal forging machine Maximum size of workpiece Length of workpiece Number of hammers Maximum striking force of each hammer Number of hammers per minute Diameter adjustment range Approved by the State Machinery Industry Bureau on May 14, 1994 4 (or 3): 360 Implementation on January 1, 2000
