Description
Technical field
The utility model relates to the electric spark linear cutting machine technical field, specifically a kind of reciprocating type line cutting machine bed electrode thread tension mechanism.
Background technology
Reciprocating type wire cutting machine tool is a kind of electric spark linear cutting machine that China created, had own independent intellectual property rights.Because the wire electrode of this lathe is toward the renaturation repeated application, compares with the unidirectional wire cutting off machine and to possess lot of advantages, but also have a lot of weak points.This lathe invention four still exists a lot of technical problems well not solve during the last ten years, is exactly wherein one as the tension force control of wire electrode.Present 90% lathe does not all have the tension control mechanism of wire electrode, still uses very original artificial tight silk method.Because everyone tensile force difference, and wire electrode in use for some time tension force diminish, so there is variation at any time in the state of discharge processing, cause operating efficiency low, the processing work roughness is poor.Also have a lot of problems in the existing tension mechanism patented technology of China, the tension force effect is bad, has only the minority lathe that this class mechanism is housed.From practice for many years, have only the weight tension mechanism that some actual effects are arranged, this mechanism mainly divides two kinds:
First kind of unidirectional tension mechanism (shown in Figure 1): half-turn on wire electrode work loop, by guide wheel (2), slide block (3), slide rail (4), weight (5) with wire electrode (1) tensioning.Because of resistance point at last half-turn, so there is tension force the workspace when wire electrode is descending.When wire electrode was up, the tension force of workspace descended, and caused the tension force difference of both direction, so the discharge machining state changes greatly.
Second kind of biaxial tension mechanism (shown in Figure 2): in wire electrode (1) work loop, by will the work electrode thread intension in loop of guide wheel (2), connecting rod (3), slide block (4), slide rail (5), steel wire rope (6), weight (7).Because of two resistance points occurring, be equivalent to the twice of active section at tension force, so be easy to generate fracture of wire near the wire electrode of wire storage cylinder (8).
Summary of the invention
The purpose of this utility model is exactly a kind of reciprocating type line cutting machine bed electrode thread tension mechanism of inventing at addressing the above problem.This mechanism is placed in the wire storage cylinder loop, makes the wire electrode in the reciprocating motion keep constant-tension, has avoided the resistance point occurring in the work loop, has solved above-mentioned prior art problem fully.
The utility model is achieved in that this tension mechanism is located in the wire storage cylinder loop, is made up of straining pulley, slide block, slide rail, guide wheel, steel wire rope and weight.The slide rail that slide block is installed is located on the fixed support that is connected with the silk cylinder base, and straining pulley is located on the slide block, and on straining pulley, the steel wire rope two ends of leaning on guide wheel to lead connect slide block and weight respectively from the wire electrode of wire storage cylinder.
The utility model is provided with tension mechanism in the wire storage cylinder loop, make the wire electrode on the wire storage cylinder produce constant-tension, and by the reciprocating motion of wire storage cylinder the wire electrode with steady-working state is transported in the work loop.Because tension mechanism is not arranged in the wire electrode work loop, so there is not the resistance point, wire electrode is in the working in reciprocating mode process, and tension force is constant, and the state of discharge processing is stable.The utility model has overcome existing tension control mechanism inconstant problem of tension force in wire electrode moves back and forth effectively, make the tension force of wire electrode remain constant, realize the stable of machining state, improved operating efficiency 20%, improved processing work surface roughness 20%.That this tension mechanism has is reasonable in design, low cost of manufacture, simple and reliable, use and install, debug characteristics easily.
Description of drawings
Fig. 1 is unidirectional tension mechanism schematic diagram.
Fig. 2 is the biaxial tension structural scheme of mechanism.
Fig. 3 is the reciprocating type line cutting machine bed electrode thread tension structural scheme of mechanism that is located in the wire storage cylinder loop.
The specific embodiment
Below in conjunction with accompanying drawing 3 the utility model specific embodiments are described:
At silk cylinder base 11 rear sides bolting support 10, slide rail 6 levels are installed in support 10 upper ends, and slide block 5 is assemblied in slide rail 6 and can be free to slide front and back.Straining pulley 4 is located on the slide block 5, from the wire electrode on the wire storage cylinder 21 on straining pulley 4.Steel wire rope 8 one ends are fixed on the slide block 5, and the other end is fixed on the weight 9 by guide wheel 7, and weight 9 is transmitted to gravity on the straining pulley 4 on the slide block 5 by steel wire rope 8.Along with slide block 5 moves backward along slide rail 6, straining pulley 4 is 1 tension of the wire electrode on the wire storage cylinder 2, and the weight that the big I of tension force is regulated weight according to the diameter of arts demand and wire electrode 1 realizes.
