Abstract
The utility model relates to a combined forging die, which comprises a die head and a die body. The outer edge of the lower end surface of the die head is fixedly connected with the outer edge of the upper end surface of the die body by means of welding. The combined forging die has the advantages that the combined forging die overcomes the shortcoming that an integral forging die cannot be reused, reduces manufacturing cost, omits integral replacement when needing to be replaced due to the fact that the abraded die head or the abraded die body only needs to be independently detached so as to be replaced, meets the requirements of energy conservation and emission reduction, is low in processing difficulty and short in processing time, not only improves integral utilization rate, but also prolongs the service life, and further improves production efficiency.
Description
Technical field
The utility model relates to a kind of combined type forging die, belongs to the technical field of forging mold.
Background technology
It is monolithic construction that employed now forging die adopted more, and in the process of forging, because the impulse force of punch press is bigger, so after using a period of time, the upper inner edge of forging die can be damaged, thereby influences the forging of machine components.For example, need the hand that is coupling of the forging die processing shaft coupling of preferred dimension precision at the shaft coupling manufacture field.Forging die after the wearing and tearing can not use repeatedly, yet the process-cycle of new forging die is long, difficulty is big, cost is high, has become influence and has produced one of key factor of forging efficient.Therefore, become and improve into the technical problem that product forging quality level and efficient are needed to be resolved hurrily the service life that effectively prolongs forging die.
At above technical problem, Chinese patent: CN201231297Y discloses a kind of hot forged mould, it is characterized in that, inner surface in the forging die chamber body is provided with embedding die, after treating the embedding die wearing and tearing, can only realize economical with materials, the purpose that increases the service life by the local replacing embedding die.But the shortcoming of this patent is: having put down in writing this embedding die in the patent document is to embed die ontology by the mode that cold cover, hot jacket or machinery are pressed into, therefore can tentatively judge, the forging die steadiness that this patent is put down in writing is poor, changes local time, and difficulty is also bigger.

A kind of method of making combinations thereof formula forging die, concrete steps are as follows:
1) lower surface of die head is provided with outer ring boss, and the upper surface of die body is provided with interior annular boss, and the height of described interior annular boss and outer ring boss is identical; The internal diameter of described outer ring boss and the external diameter of interior annular boss adapt;
2) operating personnel adopt lathe respectively at the outward flange finished edge of the upper surface of the outward flange of outer ring boss and die body, and the degree of depth of groove is the 11%-15% of forging die thickness;
3) die head is heated to 240-280 ℃, die head after the heating is enclosed within on the upper surface of die body of normal temperature, the outward flange groove of the outward flange groove of outer ring boss and the upper surface of die body forms the combination groove, when die head returns to 150-180 ℃ by the time, operating personnel become one die head and die body in the place's welding of combination groove;
4) die head after will welding and die body carry out high tempering and handle, and temperature is 640-670 ℃, is incubated 2.5-3 hour;
5) die head behind the high tempering and die body are carried out Quenching Treatment, heating-up temperature is 830-860 ℃, is incubated 2.5-3 hour;
6) die head and the die body after will quenching carries out temper, temperature 480-500 ℃, be incubated 2.5-3 hour, the combined type forging die.
According to the utility model, preferred, above-mentioned steps 3) formed combination groove is a V-butt in, and bevel angle is 85 °-95 °.
According to the utility model, preferred, above-mentioned steps 3) formed combination groove is the U-shaped groove in.
According to the utility model, preferred, above-mentioned steps 4) high tempering described in handle and step 6) described in temper be respectively in well formula tempering furnace, to carry out.
Welding is left the groove of different shape, so that more easily send into welding rod or welding wire during than steel plate at the edge fit place for through welding.Groove depth that the utility model is selected and bevel angle not only guarantee through welding, and welding is convenient, can reduce the filling amount of metal, can guarantee that again welding deformation is little, firmly the degree height.
Advantage of the present utility model is:
1, the utility model can effectively overcome the shortcoming that the monoblock type forging die can not use repeatedly, has reduced the cost of making forging die.
2, when needs are changed forging die, only need change after the dismounting separately and get final product the die head of wearing and tearing or die body occurring, need not whole forging die is changed, meet the requirement of energy-saving and emission-reduction.
3, difficulty of processing of the present utility model is low, and process time is short, has not only improved the utilization rate of mold integral, and has prolonged the life-span of forging die, and then improved production efficiency.
