Description
Technical field
The utility model relates to technical field of forging, is specifically related to a kind of pressing equipment of conical inner ring forge piece.
Background technology
At present, processing conical inner ring forge piece generally involves the step such as punching press, rolling, and the forming punching head of conventional pressing equipment all has certain pattern draft, generally, this elder generation is pressed into forging in this pattern draft undershoot, then is placed on rolling equipment by this forging and carries out rolling.
But, in rolling process, usually there is forging outwards axial float to occur, produce sunken end face, thus cause forging to be scrapped.
Utility model content
The purpose of this utility model is to solve the problem, and provides a kind of structure simple, and not easily outside axial float during rolling, avoids the pressing equipment of the conical inner ring forge piece producing sunken end face.
The technical scheme that the utility model solves the problem is as follows:
A kind of pressing equipment of conical inner ring forge piece, the pressing equipment of described conical inner ring forge piece comprises forming punching head and steps of manufacturing blanks, described forming punching head comprises the drift body, punch holder and the plunger rod that are linked in sequence, the pattern draft of described drift body is 4-12 °, and the inner edge gradient of described steps of manufacturing blanks and the pattern draft of described forming punching head match.
Preferred as technique scheme, the pattern draft of described drift body is 6-10 °, and the inner edge gradient of described steps of manufacturing blanks and the pattern draft of described forming punching head match.
Preferred as technique scheme, the pattern draft of described drift body is 8 °, and the inner edge gradient of described steps of manufacturing blanks is 8 °.
Change the pattern draft of drift body and the inner edge gradient of steps of manufacturing blanks, be equivalent to change forging center of gravity when rolling, make it more lean forward, outside axial float not easily occurs.
Preferred as technique scheme, described punch holder is identical with the diameter of punch holder itself with the junction of drift body, and such punch holder can play the supporting role to drift better.
Preferred as technique scheme, the side of described plunger rod is provided with oblique draw-in groove, for the fixed-type drift when punching press forging.
Preferred as technique scheme, the material of described forming punching head is general cold work die steel or high carbon high chromium alloy tool steel, this toughness of material is good, even tissue, there is good elevated temperature strength, toughness and high temperature resistance fatigue behaviour, can bearing temperature cataclysm, and there is high rigidity, not easy to crack.
Preferred as technique scheme, the material of described forming punching head is wolfram steel.Wolfram steel has that hardness is high, wear-resisting, intensity and a series of premium properties such as toughness is better, heat-resisting, corrosion-resistant, particularly its high rigidity and wearability, even if also substantially remain unchanged at the temperature of 500 DEG C, 1000 DEG C time, still have very high hardness, wolfram steel is generally used for the higher punching press occasion of requirement.
In sum, the utility model has following beneficial effect:
1. the pressing equipment of a kind of conical inner ring forge piece described in the utility model increases pattern draft, when rolling, outside axial float not easily occurs;
2. a kind of structure described in the utility model is simple, easy to operate.
