Abstract
The invention discloses a precision tube drawing machine. The precision tube drawing machine comprises a cam trolley, wherein wheels of the trolley are arranged upon guide rails on two sides of a transmission chain; a cam groove is formed in the center of the trolley; a cam is arranged in the cam groove; the front side of the cam is connected with a pull rod; the head of the pull rod is bent downwards to form a downward hook; a clamping block which is used for clamping a to-be-machined material is arranged on the rear side of the cam, clamps a tube when the cam moves forward, and unclamps a tube when the cam moves backward; the pull rod and the clamping block of the trolley are coordinated by using the cam; during operation, the hook at the front end of the pull rod of the trolley slightly hooks the transmission chain, the transmission chain drives the trolley to move forward, the cam moves forward, the clamping block clamps the tube, and after completely passing through a positioning device, the tube is no longer subjected to a backward pull force; the cam moves forward, the hook upwarps, the cam moves backward accordingly, the clamping block unclamps the tube, and the trolley can be pulled back to an original position by only pressing a motor button at the positioning device for next tube drawing. The precision tube drawing machine is simple and convenient.
Description
Technical field
The present invention relates to precision and automatically stretch Manifold technology field, relate in particular to a kind of accurate bench.
Background technology
At present, accurate nickel alloy capillary is roughly divided into two kinds of processing modes: the one, and rolling, is exactly by milling train down processing step by step; The 2nd, trombone slide, down processes tubing step by step by machine drawing.The advantage of tube rolling is that surfaces externally and internally quality conformance is higher, after solution treated, and stable mechanical performance; To be that the size of tube rolling is more difficult do too littlely shortcoming, and the capillary below 6mm is difficult to realize conventionally, and the precision that is exactly in addition tube rolling is low, with external diameter 6mm for example, corresponding tolerance is difficult to be controlled at ± 0.02mm in, then to have be exactly that the efficiency of rolling is low, the production cycle is long etc.The advantage of trombone slide is the capillary that dimensional accuracy is higher, can do very small diameter, and conventionally more than external diameter 0.3mm all can drawing, can draw special-shaped product etc. in addition, and shortcoming is that, inner face quality high to mould requirement difficultly controlled, spillage of material is large etc.
The current main one of trombone slide mode is exactly straight pulling method, stretching in tube apparatus at a scale exactly, drawing is less than the tubing of this device length, advantage is that precision is very high, deficiency is that efficiency is low, because the stretcher that this class trombone slide mode adopts is all cylinder conventionally, not only energy consumption is high in use for cylinder, and the efficiency of cylinder is very low, often completing a trombone slide just needs air pump again to inflate.
Summary of the invention
The present invention aims to provide a kind of accurate bench.
For realizing above-mentioned technical purpose, the present invention by the following technical solutions, a kind of accurate bench, comprise support, positioner, driving chain, stretching device and drive unit, positioner, driving chain and stretching device are all arranged on support, driving chain is arranged on the side of positioner, stretching device is located on driving chain, described stretching device is a cam dolly, dolly is connected with gearbox and motor, the wheel of dolly is located on the guide rail of driving chain both sides, the center of dolly is provided with cam path, in cam path, be provided with cam, the front side of cam is connected with pull bar, the head of pull bar is bent downwardly and forms a downward hook, hook hooks the drive rail between bench driving chain downwards, hook drives dolly forward by drive rail after hooking drive rail, when travelling forward, cam drives hook perk, the rear side of cam is provided with the fixture block for clamping rapidoprint, described fixture block clamps in the time that cam travels forward, cam loosens while moving backward.
Preferably, described motor is arranged on the below of support, and motor button is arranged on positioner place.
Preferably, described dolly adopts metal material to make.
Preferably, described dolly is provided with 4 wheels.
Different from traditional bench, the present invention has designed a cam dolly and has replaced traditional stretching device, the cam that utilizes its middle part of this dolly is coordinated pull bar and fixture block, when operation, the hook of dolly pull bar front end is taken to driving chain gently, driving chain drives dolly forward, now cam travels forward, fixture block clamps tubing, when tubing process positioner, can be subject to a pulling force backward, this pulling force is passed to cam by fixture block, the pulling force forward that the pulling force backward that cam is subject to and chain impose on cam by pull bar forms a balance, tubing is just driven forward by dolly, Deng tubing completely after positioner, tubing is no longer subject to pulling force backward, cam travels forward, drive the hook of dolly to be upturned forward, depart from driving chain, now cam is also no longer subject to driving chain and imposes on by pull bar the pulling force of cam, cam moves backward, fixture block is decontroled tubing, the motor button that now only need to click positioner place just can retract dolly original position and carry out trombone slide next time, simple and convenient, compare original very large cylinder, not only greatly save energy consumption, also improve operating efficiency.
