Abstract
The utility model relates to a component of a cold drawing machine, in particular to an outer drawing die of the cold drawing machine, which is mainly used for drawing thin-walled tubes. The outer drawing die is a conical die with a die bearing, the length L of the die bearing ranges from 15%D to 18%D, and the D is the diameter of a tube to be drawn. Thin-walled tubes made by the outer drawing die, such as gas cylinder tubes and the like, can meet specified requirements without a straightening machine for straightening, thereby avoiding the problem of tube pressing damage of the tubes during straightening in a traditional process.
Description
Technical field
The utility model relates to a kind of assembly of drawbench, refers in particular to a kind of drawing external mold of drawbench, and the drawing external mold of this drawbench is mainly used in drawing thin wall type tubing.
Background technology
Tubing is flexural deformation easily after process is pulled out the machine drawing, so need after the drawing just can reach requirement by the straightener aligning, yet for some thin wall type tubing, as gas cylinder tube etc., because tube wall is thinner, when using common straightener to align pipe, easily pipe is shriveled, influence quality.Though the equipment for straightening of supporting special use is arranged at present, use this equipment investment bigger, cause production cost higher.
The utility model content
The technical problems to be solved in the utility model is: the phenomenon that shrivels easily takes place when thin wall type tubing such as gas cylinder tube etc. are aligned with straightener after drawing, influence product quality, and use special-purpose equipment for straightening to cause production cost too high, provide a kind of drawing external mold that is specifically designed to the drawbench of drawing thin wall type tubing in order to address this problem, the thin wall type tubing that uses this drawing external mold to extract can be in order to avoid aligning.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of drawing external mold of drawbench, be mainly used in drawing thin wall type tubing, this drawing external mold is Su Shimo, has calibrating strap, the length L of described calibrating strap is 15%～18%D, and wherein D is a diameter for the treatment of the tube drawing material.
The beneficial effects of the utility model are: the thin wall type tubing that uses this drawing external mold draw to go out, as gas cylinder tube etc., need not can reach the requirement of regulation again through the straightener aligning, therefore evade the tubing crushing problem that occurs when aligning process in the traditional handicraft.
Description of drawings
Below in conjunction with drawings and Examples this practical new work type is further specified.
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1. drawing external mold 2. calibrating straps
The specific embodiment
A kind of drawing external mold 1 of drawbench is mainly used in drawing thin wall type tubing, and this drawing external mold 1 is Su Shimo, has calibrating strap 2, and the length L of calibrating strap 2 is 15%～18%D, and wherein D is a diameter for the treatment of the tube drawing material.
Key of the present utility model is in the design of drawing external mold calibrating strap length.The calibrating strap length of present common tube-drawing external mold is (10%～12%) D, and the calibrating strap length of the utility model drawing external mold is 15%～18%D, and promptly length has extended 50% than common tubing drawing die calibrating strap length.This scheme is exempted the effect of aligning operation specially at the design of thin wall type tubing by adjusting the length of drawing external mold calibrating strap, can reach the tubing that draw is gone out.
With drawing
426 * 6 gas cylinder tube is an example, the linearity of tubing can reach 1/1000 (10 meters maximum deflection 15 of total length) behind the draw, therefore exempt to align and just can satisfy 10 meters maximum deflection of total length less than 20 requirement, and if use common drawing external mold to carry out draw, the linearity of tubing is 2/1000 (10 meters maximum deflection 30 of total length) behind the draw.
Claims (1)
1. the drawing external mold (1) of a drawbench is mainly used in drawing thin wall type tubing, and this drawing external mold (1) is Su Shimo, has calibrating strap (2), it is characterized in that: the length L of described calibrating strap (2) is 15%～18%D, and wherein D is a diameter for the treatment of the tube drawing material.
