Abstract
The utility model discloses a reciprocating type cold drawing machine which has simple structure and can carry out super length drawing on pipes and bars. The cold drawing machine comprises a drawing die holder arranged at a machine tool charging initial end, a drawing trolley which can move along a guide rail arranged on a machine tool, an annular traction system which tracts the drawing trolley as well as a power system which drives the annular traction system, wherein the drawing trolley is fixedly connected with the annular traction system. The drawing trolley is fixedly arranged on the annular traction system and is driven by a forward reverse motor to do reciprocating movement, and drawing can be carried out on super long pipes and bars for multiple times until the specified length is obtained; compared with a hook type cold drawing machine, the drawing trolley operates stably, and no uncoupling is required, thus causing the cold drawing effect to be good and greatly improving the production efficiency. Compared with a cylinder spiral cam type cold drawing machine, the reciprocating type cold drawing machine in the utility model has simple structure, low cost and immeasurable market potential.
Description
Technical field
The utility model relates to the metalworking technology field, relates in particular to the cold-drawn machine of bar or tubing.
Background technology
Existing pipe bar cold-drawn machine is broadly divided into two kinds, and a kind of is coupling type, and also having a kind of is the cylindrical screw cam-type.
Wherein the coupling type cold-drawn machine is with linking up with the stretching primary coupler on the unidirectional loop trailer system, drawing the stretching dolly thus and moving, being stretched by stretching dolly pinch tube bar.After stretching finished, will break off relations this moment to the stretching dolly, the stretching dolly retracted again or get back to original position by gradient free skating, beginning stretching next time.Because adopt the drag hook traction, the stretching dolly can cause and tremble that speed is inhomogeneous in whole drawing process, the cold drawn effect of influence pipe bar, production efficiency is low.After in addition the pipe bar being carried out the stretching of a specification length, cut off the pipe bar and could allow the stretching dolly reset, carry out stretching next time.Surpass the stretching of the pipe bar of stretching dolly mobile displacement for those specification length, can not repeatedly stretch, just cut off the pipe bar up to required specification length, because the stretching dolly is after finishing one-off drawing, allow the stretching dolly reset if not cutting off in tension breaks off relations under the situation of pipe bar by force, be easy to cause production accident.
As for another kind of cylindrical screw cam-type cold-drawn machine, be by the cylindrical screw cam that the rotates dolly straight reciprocating motion that realizes stretching, can repeatedly be stretched to required specification length to the pipe bar, cut off again, solved the existing technical problem of above-mentioned coupling type cold-drawn machine fully, but because its complex structure, cost is high, makes the market competitiveness have a greatly reduced quality.
The utility model content
Technical problem to be solved in the utility model provides a kind of simple in structure, can carry out the reciprocating type cold-drawn machine that the overlength degree stretches to the pipe bar.
Technical problem to be solved in the utility model is to realize by following technical scheme: a kind of reciprocating type cold-drawn machine, comprise the stretching die holder that is located at lathe charging initiating terminal, the stretching dolly that can move along the guide rail that is located on the lathe, drawing the loop pulling system of stretching dolly and the dynamical system that drives annular trailer system, it is characterized in that: described loop pulling system comprises at least one conduction chain or rope, fixedly connected with the two ends of described stretching moving of car direction respectively in the two ends of described conduction chain or rope, described dynamical system provides power by clockwise and anticlockwise motor, and the universal driving shaft of described clockwise and anticlockwise motor is provided with brake apparatus.
On the basis of the above, described conduction chain is provided with two, the parallel respectively both sides of being located at lathe, and be provided with the up guide rail and the descending guide rail of conduction chain.
On the basis of the above, described every conduction chain is plugged into by the chain of two kinds of different sizes and is formed, and wherein connecting chain that the stretching dolly points to that end of lathe charging initiating terminal, to connect the chain specification of the stretching dolly other end relatively little.
Adopt the beneficial effect that the utility model brought: because the stretching cart stationary is installed in the loop pulling system, drive reciprocating motion by clockwise and anticlockwise motor, can the pipe bar of overlength repeatedly be stretched, up to required specification length, relative coupling type cold-drawn machine, the stretching trolley travelling is steady, need not to break off relations, make cold drawn respond wellly, production efficiency greatly improves.Also have the utility model simple in structure with respect to cylindrical screw cam-type cold-drawn machine, it is cheap to fake, and has immeasurable market potential.
Description of drawings
Fig. 1 is the reciprocating type cold-drawn machine top structure of a utility model schematic diagram;
Fig. 2 is that the A of Fig. 1 is to the side structure schematic diagram.
The specific embodiment
A kind of reciprocating type cold-drawn machine, comprise the stretching die holder 2 that is located at lathe 1 charging initiating terminal, can be along stretching dolly 3, loop pulling system of drawing stretching dolly 3 that the guide rail that is located on the lathe 1 moves and the dynamical system that drives annular trailer system.
As preferred embodiment a kind of, the loop pulling system comprises two conduction chains 5, these parallel respectively both sides of being located at lathe 1 of two conduction chains 5, fixedly connected with the two ends of stretching dolly 3 directions of motion respectively in two ends, the drive sprocket that is looped around lathe 1 two ends simultaneously to 6 and driven sprocket on 7, and be provided with the up guide rail 8 and the descending guide rail 9 of conduction chain 5.Dynamical system provides power by clockwise and anticlockwise motor 4, and the universal driving shaft of clockwise and anticlockwise motor 4 is provided with brake apparatus 10.Certainly the loop pulling system can adopt alternate manner, and is above-mentioned as preferred embodiment a kind of such as pull-cord, just in order to make 3 operations of stretching dolly more steady.
In order farthest to reduce cost, as the preferred embodiment of another kind, every conduction chain 5 is plugged into by the chain of two kinds of different sizes and is formed, and wherein connecting chain that stretching dolly 3 points to that end of lathes 1 charging initiating terminal, to connect the chain specification of stretching dolly 1 other end relatively little.
