Abstract
The invention discloses a reciprocating-moving-type hydraulic drawbench, which solves the problems that an existing device cannot directly draw long workpieces, the drawbench is high in cost, and the machine body is long. The reciprocating-moving-type hydraulic drawbench is characterized by also comprising a left driving oil cylinder, a right driving oil cylinder and a draw bar, wherein the left driving oil cylinder and the right driving oil cylinder are arranged on a front part machine body; the draw bar is provided with a positioning groove; the outer end parts of piston rods of the driving oil cylinders are connected with a stress beam; the middle part of the stress beam is provided with an electromagnetic positioning card, and the electromagnetic positioning card clamps the draw rod by the positioning groove; the other end of the draw bar is connected with a hydraulic fixture for clamping workpieces. According to the invention, hydraulic force of piston cavities of two parallel hydraulic driving oil cylinders is taken as a power source, the requirement for cylinder diameter is lowered, and the idle stroke and return stroke are rapid; the strokes of the driving oil cylinders are related to the one-time moving distance, and the same workpiece can be subjected to reciprocating-moving-type drawing for multiple times, so that workpieces with any length can be drawn by driving oil cylinders with short cylinder diameter and strokes; only a mold holder is required; the machine body is very short; the manufacturing cost is low.
Description
Technical field
The present invention relates to a kind of hydraulic drawbench, relate to or rather the hydraulic drawbench that a kind of reciprocally vibration is used.
Background technology
Hydraulic pressure cold drawing machine is by allowing workpiece to be machined (material) by refrigeration distortion of running business into strong one such as moulds, thereby reaches the requirement of shape, size, surface quality and intensity aspect, efficiently realizes the object of ELEMENTARY INTRODUCTION TO NON.Traditional hydraulic pressure cold drawing machine has following problem: 1, drawing Workpiece length is subject to the restriction of traction fluid compressing cylinder stroke, and the directly draw of overlength, needs segmentation drawing, so not only time-consuming, has also reduced stock utilization.Want the workpiece elongating, will synchronously lengthen the stroke of traction fluid cylinder pressure and fuselage length etc., cost is too high.2, hydraulic drawbench cost is high, drawing oil cylinder cylinder diameter is large (diameter is generally all more than φ 400mm), stroke is generally all wanted more than 10 meters, such hydraulic cylinder cost is very high, also have three relatively large seat boards, 8 stay tubes and pull bar, fuselage etc., cost is generally all wanted more than 2,000,000 yuan, what have is higher, also has even up to ten million.3, take a large amount of factory buildings, fuselage is longer, with 10 meters of workpiece of drawing, calculates, and general drawbench is always about 50 meters of left and right.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art provides a kind of reciprocal vibration formula hydraulic drawbench, and simple in structure, fuselage is short, cost is low, and drawing workpiece distance is not driven oil cylinder stroke to restrict, workpiece that can drawing random length.
The present invention includes forward fuselage, die holder, rear portion fuselage, die holder is arranged between forward fuselage, rear portion fuselage, be characterised in that: also comprise left driving oil cylinder, right driving oil cylinder, pull bar, left driving oil cylinder, right driving oil cylinder are arranged in forward fuselage, and described pull bar is provided with and left driving oil cylinder, locating slot that right driving oil cylinder stroke is corresponding; The piston rod outer end of left driving oil cylinder, right driving oil cylinder connects a bearing beam, and the middle part of bearing beam is provided with electromagnetic location card, and electromagnetic location cartoon is crossed locating slot and blocked pull bar; Pull bar one end is through the interstitial hole of bearing beam, and the other end is connected with the hydraulically operated fixture of holding workpiece.
Between described left driving oil cylinder and die holder, also arrange apart from frame between right driving oil cylinder and die holder, apart from frame, for fixed drive oil cylinder, and make itself and die holder maintenance certain distance.
Operation principle:
The outer mold that die holder is passed in the end of workpiece is (if there is internal mold, the same internal mold of implanting), the hydraulically operated fixture that pull bar connects is clamped workpiece, the other end of pull bar is through the interstitial hole of bearing beam, and block with electromagnetic location card, two hydraulic jacks of synchronous driving, can extract workpiece the length of a stroke.Unclamp electromagnetic location card, allow bearing beam return with piston rod, and pull bar and workpiece are motionless, after hydraulic cylinder backhaul finishes, electromagnetic location cartoon is crossed locating slot and is again blocked pull bar, drives two hydraulic jacks to carry out second step drawing.Through the drawing of the reciprocal vibration formula of several times, just can drawing go out the length that whole workpiece needs.
The position of left driving oil cylinder, right driving oil cylinder from die holder distance more away from, pull bar is longer, workpiece that can drawing is just longer.Therefore between driving oil cylinder and die holder, be provided with apart from frame, pull open the distance that drives oil cylinder and die holder, for workpiece is abdicated length space.If spreading pull bar, just can adapt to the cold-drawn processing of longer workpiece.
As shown from the above technical solution, the present invention has following beneficial effect: 1, utilize the hydraulic coupling of the plunger shaft of two parallel hydraulic driving oil cylinders to do power source, like this requirement of cylinder diameter is just reduced a lot, and idle running backhaul is fast.Traditional hydraulic drawbench is a traction cylinder, and use is the area of rod end chamber.2, the stroke that drives oil cylinder only with single vibration distance dependent, and can not restrict the length of institute's drawing workpiece, can carry out the drawing of the reciprocal vibration formula of several times to same workpiece, the driving oil cylinder that available like this cylinder diameter and stroke are less, drawing goes out the workpiece of random length.3, compare tradition, only need a die holder, do not need traditional cylinder seat and tailstock, also do not need stay tube etc., so fuselage is very short, cost is low, length is approximately the Workpiece length of 2 times, and traditional drawbench fuselage is greater than the Workpiece length of 4 times.
