Embodiment Construction

[0018] The following describes the embodiments of the present invention in detail.

[0019] The invention provides a ball joint processing technology, the ball joint includes a ball head and a pipe fitting, the ball head and the pipe fitting are integrally formed by forging, the processing technology includes the following steps:

[0020] a1. Material preparation: select the appropriate blank according to the size of the drawing;

[0021] a2. Annealing: heat the billet to 900-1000°C, keep it warm for 3-4 hours, cool the billet to 300°C with the furnace, and then take it out of the furnace for air cooling;

[0022] a3. Hot forging: heating the blank to 1000-1100°C to forge the ball head to obtain the blank, and then cool it naturally;

[0023] a4. Clamping: Clamp the blank on the chuck, turn the end face of the pipe, and drill the center hole for positioning;

[0024] a5. Machining the outer circle: According to the size of the drawing, the pipe fittings are rough-turned, lea...

Abstract

The invention provides a machining technology for a ball hinged joint. The machining technology comprises the following steps of a1, preparing materials; a2, carrying out annealing, specifically, heating a blank to 900-1000 DEG C, carrying out heat preservation for 3-4 hours, cooling the blank to 300 DEG C along with a furnace, then discharging the blank out of the furnace and carrying out air cooling; a3, carrying out hot forging, specifically, heating the blank to 1000-1100 DEG C for forging and pressing to form a ball head so as to obtain a blank part and then carrying out natural cooling;a4, carrying out clamping, specifically, clamping the blank on a chuck, turning the end surface of a pipe and drilling a positioning center hole; a5, machining an outer circle, specifically, roughly turning the part of the pipe according to the drawing size, reserving 1-5 mm as the allowance and carrying out finish turning on the outer circle; a6, carrying out punching; a7, machining the ball head, specifically, clamping the blank again, turning the end surface, drilling the positioning center hole, replacing a drill bit, expanding the hole to reach a specified size and turning an annular groove inside the hole according to the drawing size; a8, carrying out heat treatment; and a9, carrying out the three steps, firstly, grinding a workpiece to reach a specified size, secondly, cleaning anddrying the workpiece and thirdly, carrying out electroplating treatment on the workpiece according to the requirements. The machining technology for the ball hinged joint has the advantages that themachining steps are clear, the machining efficiency is high, and the quality is good.

Description

technical field [0001] The invention relates to a processing technology, in particular to a ball joint processing technology. Background technique [0002] The common parts of each series of "ball hinge joints" were introduced by Luoyang Mining Machinery Factory from Sweden ASEA Company in 1986, and are important parts connecting the vertical shaft of the hoist monitor and the reducer. New structure, small size, light weight, but complex processing, is a blank in the domestic manufacturing industry. "Ball joints" are divided into "single ball joints" and "double ball joints". Because it is an important component, it has high requirements for its processing quality and strength. Contents of the invention [0003] 【1】Technical problems to be solved [0004] The technical problem to be solved by the present invention is to provide a ball joint joint processing technology with high processing efficiency and good quality. [0005] 【2】Technical solution to solve the problem ...
