Abstract
An automotive lower front arm guide pipe processing technology is characterized by including selecting a standard pipe with the internal bore diameter being more than that of a guide pipe by 1-2 millimeters and the external circumferential diameter being more than that of the guide pipe by 2-4 millimeters, using a special extrusion die for extruding the selected standard pipe into a finished product profile, blanking the profile into a short material according to design requirements, subjecting the two ends of the short material to facing and internal bore turning, chamfering and burring so as to obtain the guide pipe. The automotive lower front arm guide pipe processing technology has the advantages of little allowance for machining, high material utilization ratio, low cost and short production period, thereby being high in popularization and application value.
Description
Technical field
The present invention relates to a kind of metal Cold-forming process, particularly underarm catheter fabrication technique before a kind of automobile.
Background technology
At present, before automobile, underarm conduit adopts round steel pipe to be processed being made mostly.Due to section bar specification, can not to fully meet processing request, endoporus and Excircle machining surplus big, and section bar is non-standard tubing, it is necessary to mold developing or be customized producing, and production cycle length, cost are high.
Summary of the invention
The invention aims to overcome the above-mentioned weak point of prior art, and provide a kind of allowance few, stock utilization is high, cost is low, underarm catheter fabrication technique before automobile with short production cycle.
For achieving the above object, the concrete assembly method that the present invention adopts is first to select diameter of bore more than product guide pipe inner hole diameter 1～2 millimeter, outside diameter more than the standard tubing of product conduit outside diameter 2～4 millimeters, use dedicated extruded mould that above-mentioned selected standard tubing is squeezed into product section bar, further according to designing requirement, the said goods cutting of material become the short material of product, then respectively the short material two ends of product being carried out car face, endoporus, chamfering, deburring become product conduit.
Due to the fact that the above processing method of employing, allowance is few, and stock utilization is high, cost is low, with short production cycle, has good application value.
Detailed description of the invention
First select diameter of bore more than product guide pipe inner hole diameter 1～2 millimeter, outside diameter more than the standard tubing of product conduit outside diameter 2～4 millimeters, use dedicated extruded mould that above-mentioned selected standard tubing is squeezed into product section bar, further according to designing requirement, the said goods cutting of material become the short material of product, then respectively the short material two ends of product being carried out car face, endoporus, chamfering, deburring become product conduit.
Claims (1)
1. underarm catheter fabrication technique before an automobile, it is characterized in that first selecting diameter of bore more than product guide pipe inner hole diameter 1～2 millimeter, outside diameter more than the standard tubing of product conduit outside diameter 2～4 millimeters, use dedicated extruded mould that above-mentioned selected standard tubing is squeezed into product section bar, further according to designing requirement, the said goods cutting of material become the short material of product, then respectively the short material two ends of product being carried out car face, endoporus, chamfering, deburring become product conduit.
