Abstract
The invention discloses the drawing process of a kind of laminated multi-layer workpiece；The advantage of the multilayer pipe obtained by the method is that the external diameter of each layer of pipe is interior the most consistent through data with its pipe of outer one layer；Multiple workpiece are stacked together and stretch, this ensures that thering the concordance of institute's trombone slide, the precision keeping pipe is consistent, improves the quality of production of pipe, improve yield rate, meanwhile, being also greatly reduced the cost of product, overall processing process is fairly simple, easy to operate, can pull out multiple pipe with a mould, yield is big, good in economic efficiency.
Description
Technical field
The present invention relates to the drawing process of a kind of workpiece, particularly relate to the drawing process of a kind of laminated multi-layer workpiece, belong to the ring steel belt processing technique field of infinitely variable transmission.
Background technology
At present, a lot of automobiles and electronics field are required for using metal drive belt, and the steel band required for this series products all needs to meet bigger intensity, it is accomplished by metal with certain thickness for meeting this intensity, but thickness is accomplished by the most greatly the biggest bending radius, also it is accomplished by bigger drive, but the drive beaten just takies much room；But, a lot of automobiles and electronic product do not allow take big space or cannot install the biggest drive at all.
In order to solve this contradiction, we can be the steel bands use stacked together of the most how thin of annular, the structure of a lot of ring steel belt stackings is the intensity that can ensure that transmission band, and has the radius that can make drive the least, because the bending radius needed for the very thin thickness of every transmission band is the least.
At present, in known technical field, drawing process majority is that single monolithic piece stretches, and the internal diameter of pipe when thus cannot ensure twice stretching keeps consistent, is difficult to control the concordance of the precision to pipe, causes the qualification rate of product to be substantially reduced；If the concordance of product cannot be ensured, then cannot produce qualified product, the batch that just cannot meet same pipe uses demand.
Summary of the invention
The present invention is in order to make up the deficiencies in the prior art, it is provided that the drawing process of a kind of laminated multi-layer workpiece, and the method can effectively realize the stretching together of laminated multi-layer workpiece, and ensure that the concordance that multilayer workpiece stretches.
The drawing process of a kind of laminated multi-layer workpiece, it is characterised in that specifically comprise the following steps that
The first step, chooses suitable metal material；
Second step, is placed on selected metal material in off-the-shelf mould；
3rd step, adjusts the pressure of master cylinder, makes pressure limit in the range of 8 2000 ton forces；
4th step, stretches workpiece, and metal material is pulled into tubulose.
Improve further, in step one, described metal material be thickness be the metal material of 0.1-2mm.
Improving further, in step one, described metal material is rustless steel, steel alloy, aluminum, ferrum, copper, titanium or other metals.
Improving further, in step 2, described mould is die and punch；And the internal diameter of die is equal to the thickness sum of punch external diameter with metal material.
Improving further, in step 4, the pipe pulled out, the thickness of tube wall is 0.1-2mm, and bore is 10-2000mm, and the height of pipe is 3-2000mm.
Compared with prior art, use such scheme, the invention has the beneficial effects as follows: multiple workpiece are stacked together and stretch by the present invention, this ensures that thering the concordance of institute's trombone slide, the precision keeping pipe is consistent, improves the quality of production of pipe, improve yield rate, meanwhile, being also greatly reduced the cost of product, overall processing process is fairly simple, easy to operate, can pull out multiple pipe with a mould, yield is big, good in economic efficiency.
Detailed description of the invention
The drawing process of a kind of laminated multi-layer workpiece, it is characterised in that specifically comprise the following steps that
The first step, chooses suitable metal material, concrete selected metal material be thickness be the metal material of 0.1-2mm；Described metal material is rustless steel, steel alloy, aluminum, ferrum, copper, titanium or other metal materials；
Second step, is placed on selected metal material in off-the-shelf mould；Concrete described mould is die and punch；And the internal diameter of die is equal to the thickness sum of punch external diameter with metal material；
3rd step, adjusts the pressure of master cylinder, makes pressure limit in the range of 8 2000 ton forces；
4th step, stretches workpiece, and metal material is pulled into tubulose；The pipe pulled out, the thickness of tube wall is 0.1-2mm, and bore is 10-2000mm, and the height of pipe is 3-2000mm；
The advantage of the multilayer pipe obtained by the method is that the external diameter of each layer of pipe is interior the most consistent through data with its pipe of outer one layer.
If if ensure that the interior warp of a pipe is accomplished with another external diameter consistent being difficult to of high accuracy by all means by monolithic stretching, but it is the most consistent with the interior warp of other arm just can be relatively easy to, by the method, the external diameter obtaining an arm.
The present invention solves the external diameter of an arm with the interior of its last layer pipe through reaching the problem that high accuracy is consistent.
Multiple workpiece are stacked together and stretch by the present invention, this ensures that thering the concordance of institute's trombone slide, the precision keeping pipe is consistent, improves the quality of production of pipe, improve yield rate, meanwhile, being also greatly reduced the cost of product, overall processing process is fairly simple, easy to operate, can pull out multiple pipe with a mould, yield is big, good in economic efficiency.
The present invention is not limited to above-mentioned specific embodiment, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, done all conversion, within all falling within protection scope of the present invention.
