To plate drawing machine.
Plate drawing machine is a kind of metal pipe material drawing equipment of high speed, and it can realize the tube reducing of tubing and subtract wall.Existing disk
Drawing die seat assembly in machine drawing is made up of straightener, drawing external mold, rotary shaft, is realized together by drawing external mold core print
Time tube reducing of secondary stretching, i.e., one and subtract wall, stretching is then drawn using the disk of multi-pass, pipe diameter and wall thickness is reached product
Product requirement.
In the prior art, the Chinese utility model patent of Application No. CN201520419850.5, disclosing one kind is used for
The plate drawing machine of metal pipe material drawing, the operation of head processed and drawing feeding is substituted by mechanized equipment, realizes automation feeding
Function, reduces artificial intensity, improves efficiency, but can not realize equipment multi-pass stretch function on the same stage.Therefore, in metal pipe material
In drawing process, preferably improve production efficiency, reducing energy consumption, it is ensured that the stability of product quality is, it is necessary to drawing die holder
Structure is optimized and improved.
Utility model content
In view of the shortcomings of the prior art, the utility model provides a kind of bimodulus draw-off gear for air-conditioning coil pipe, pass through
Twice drawing-die is set, can simultaneously be realized secondary tube reducing and once be subtracted the bimodulus drawing process of wall, efficiency high.
The utility model is achieved through the following technical solutions.
A kind of bimodulus draw-off gear for air-conditioning coil pipe, including the draw-off gear being connected with straightener, described drawing
Device includes the first drawing-die and the finishing die that set gradually；The just drawing-die include first drawing-die seat and in first drawing-die seat just
Drawing outer die orifice, the finishing die includes finish draw die holder and the outer die orifice of the finish draw in the finish draw die holder；It is described just to draw outer die orifice
With the through hole that is passed through for tubing is provided with the outer die orifice of finish draw.
A drawing-die is provided only with most of draw-off gear of the prior art, therefore in the drawing process of tubing, is needed
Wanting the drawing of twice independence to operate could complete stretching, and tedious process takes and efficiency is low.In the utility model, by just drawing
Mould and finishing die set gradually, and the tubing in straightener out is directly over stretching and finish draw at the beginning of this twice and stretch：Just
Drawing-die is used for the empty of tubing and draws tube reducing, the tube reducing that finishing die is used for tubing to subtract wall；One-off drawing operation realize twice tube reducing and
Once subtract wall, shorten operation, save the substantial amounts of time, improve efficiency, and the lumber recovery of product is high.
Preferably, the through hole arrival end just drawn on outer die orifice and the outer die orifice of finish draw is provided with round table-like deformed area, should
The side wall angle of round table-like deformed area is 10 ° ~ 15 °, it is ensured that when tubing enters die orifice outside the just outer die orifice of drawing and finish draw, tube surfaces
It is not scratched.
Preferably, being provided with floating core head in the outer die orifice of the finish draw.In the drawing process of tubing, the floating core head is placed in
Inwall in tubing inner chamber with tubing offsets, it is ensured that pipe material inner wall thickness is uniform in drawing process, inner wall smooth, realizes good
Subtract wall effect.
Preferably, just drawing-die and the finishing die are on diaphragm capsule, it is ensured that the stability of drawing pipe and same during work
Step property.
Compared with prior art, the utility model has the advantages that：There is first drawing-die and finish draw there is provided one kind
The bimodulus draw-off gear of mould, can once complete the drawing process of tubing, realize that secondary tube reducing once subtracts wall, reduce disk and draw stretching
Passage, shortens technological process, improves efficiency and product lumber recovery.
Brief description of the drawings
