Abstract
A reducing die comprises a tube cavity penetrating two ends, wherein the tube cavity comprises a sizing zone which is arranged at a position near an outlet end; and two ends of the sizing zone are expanded outwards. According to the invention, the two ends of the sizing zone are expanded outwards, so that the case that a head end is broken during drawing cannot occur easily, the yield and the production efficiency are improved.
Description
Technical field
The object of the present invention is to provide a kind of reducing die.
Background technology
The undergauge of metal material is achieved by drawing usually, but, during by drawing processed finished products, finally can cut away the head end made when grinding head, not only waste a large amount of materials, and yield rate be very low.When head is ground in drawing, if with press compacting, blank head end may be made to be out of shape uneven, and the situation extruding crack may be there is, very easily occur the phenomenon breaking head end like this when drawing is shaping, therefore, greatly reduce production efficiency.
Summary of the invention
The object of the present invention is to provide a kind of reducing die that can improve yield rate.
The object of the present invention is achieved like this, a kind of reducing die, comprises the tube chamber at through two ends, and described tube chamber comprises calibrating strap, and described calibrating strap is arranged on the nearer position of the distance port of export, and the two ends of calibrating strap are the type of extending out.Because the two ends of calibrating strap of the present invention are the type of extending out, not easily there is the situation breaking head end during drawing, not only increase yield rate, and improve production efficiency.
In order to make undergauge process more smooth, the port of export of above-mentioned calibrating strap extends out as outlet band, and the other end extends out as compression strap and lubrication belt.
In order to improve the order of yield rate further, above-mentioned outlet band is for extending out arc.
In order to drawing is more smooth, above-mentioned lubrication belt is arranged on arrival end, and compression strap is arranged between lubrication belt and calibrating strap.
Lubrication belt is tubaeform, can lubricating fluid be allowed when the draw to be full of blank surface along flaring opening, reach the effect of lubrication.
In order to ensure drawing quality, the length of compression strap is greater than the length of lubrication belt.
The present invention has following beneficial effect:
1, the two ends of the calibrating strap of reducing die of the present invention are the type of extending out, and not easily occur the situation breaking head end, not only increase yield rate, and improve production efficiency during drawing.
2, the openend of reducing die of the present invention is arc, and entrance is provided with lubrication belt, and the frictional force between blank and reducing die can be made to reduce, thus driving force when reducing the machine for shrinking draw, and contribute to the service life extending reducing die)
3, structure of the present invention is simple, easy to use.
Accompanying drawing explanation
Fig. 1 is reducing die structural representation of the present invention;
Fig. 2 is embodiment of the present invention reducing die working state schematic representation.
In figure, 1. tube chamber, 2. calibrating strap, 3. outlet band, 4. compression strap, 5. lubrication belt, 6. blank.
Detailed description of the invention
Embodiment, a kind of reducing die is tubulose, and comprise the tube chamber 1 at through two ends, tube chamber 1 comprises calibrating strap 2, and calibrating strap 2 is arranged on the nearer position of the distance port of export, and the two ends of calibrating strap 2 are the type of extending out.Calibrating strap 2 extends out as outlet band 3 to the port of export, and the other end extends out as compression strap 4 and lubrication belt 5.The vertical section of outlet band 3 is arc.Lubrication belt 5 is arranged on arrival end, and lubrication belt 5 is tubaeform, and compression strap 4 is arranged between lubrication belt 5 and calibrating strap 2.
The length of compression strap 4 is greater than the length of lubrication belt 5.
Be fixed on the die holder of machine for shrinking by reducing die of the present invention, die holder rear end is connected with moveable bearing, supports overhead gage at blank 6 tail end, controls machine for shrinking and moves to blank 6 with mould by die holder, finally by blank, realize undergauge.
