Description
Affiliated technical field
The utility model relates to a kind of metal plastic deformation process equipment, especially a kind of drawbench that does not have the two-way continuous drawing of idle stroke.
Background technology
By plastic deformation metal being processed is a kind of process commonly used, wherein tubing, bar draw processing commonly used.Draw equipment commonly used has hydraulic drawbench and chain drawbench.The main function components of existing known drawbench is the core bar seat of outer mould base that the drawing external mold is housed, location internal mold core bar and the drawing car that chuck moves reciprocatingly is housed.(existing multistrand drawing mill can have several drawn wires on a drawn wire, i.e. a plurality of workpiece of drawing simultaneously, but also be unidirectional drawing, the backhaul of drawing car also is an idle stroke) outer mould base and drawing external mold, core bar seat have only one, and the drawing car also has only an end that the chuck of holding workpiece is housed.Before the drawing car advanced to outer mould base during work under the driving of hydraulic jack or chain, its chuck was clamped the workpiece front end that passes external mold, hydraulic jack or chain commutation then, and the drawing car retreats and leaves outer mould base, hauls workpiece and passes external mold and finish drawing work.In this working cycles of existing single strand drawing machine or multistrand drawing mill, the drawing car that moves reciprocatingly all is an idle stroke to the motion of outer mould base direction, and drawing process is interrupted, has both influenced the raising of production efficiency, also increases energy resource consumption.This problem has become the primary obstacle of drawing technique development.
Summary of the invention
The purpose of this utility model provides a kind of drawbench of new structure type, realizes not having the two-way continuous drawing of idle stroke, to significantly improve production efficiency, to reduce energy consumption of unit product, can obtain better economic benefit.
For achieving this end, technical solution adopted in the utility model is as follows: this drawbench is made up of attaching parts, power-driven system between outer mould base, core bar seat, lathe bed, die holder.It is characterized in that two outer mould bases are arranged on a drawn wire, an external mold is housed in each outer mould base, two core bar seats are arranged, an internal mold core bar is housed in each core bar seat, Workpiece clamping head all is equipped with at drawing car two ends.The centre bore axis of two external molds and two core bar seats point-blank, outer mould base and core bar seat put in order be two outer mould bases in the centre, two core bar seats are respectively in the outside of two outer mould bases.The drawing car places between two outer mould bases, does linear reciprocating motion on lathe bed, and the center line of drawing car two end pieces chuck and the centre bore axis of two outer mould bases and two core bar seats are point-blank.Drawing is automobile-used to be installed in two single-acting hydraulic jacks on the outer mould base respectively, perhaps with the double-act-ing hydraulic J-Horner that is installed on one of them outer mould base, perhaps uses chain drive.When the drawing car adopts hydraulic jack to drive, with the cylinder barrel connection outer mould base and the core bar seat of hydraulic jack.When the drawbench of this pattern is worked, the drawing car is when a direction motion, and the chuck of one end is extracted workpiece from the outer mould base of a side, and this chuck discharged workpiece when stroke finished, the chuck of the drawing car other end is clamped the workpiece in the opposite side outer mould base, and the drawing car oppositely continues drawing.It all is impulse stroke that this two-way drawing makes the positive revesal of drawing car linear reciprocating motion, does not have idle stroke, and drawbench has been realized the continuous drawing operation.
The beneficial effects of the utility model be following some, owing to realized the two-way continuous drawing operation that does not have idle stroke, the production efficiency of drawbench is improved, the ratio that the ratio that compare cost increases with existing drawbench increases much smaller than efficient, particularly when adopting hydraulic jack to drive, cylinder barrel connection outer mould base and core bar seat with hydraulic jack have replaced attaching parts between independent die holder, provide cost savings.Adopt many one-way cylinders to drive the pattern that the drawing turner is done jointly, every oil cylinder cylinder diameter can be less, and when large-tonnage, the total cost of oil cylinder can reduce a lot than the only big cylinder diameter oil cylinder of existing list.These variations make cost performance of the present utility model significantly be better than existing type.
