Embodiment 1

[0034] The processing method of the four-station die using H13 steel as a blank comprises the following steps:

[0035] 1) Carry out general car processing on the blank, and leave a machining allowance of 3 mm according to the final product size, and then process the inner hole part of the CNC lathe, and leave a machining allowance of 1 mm for the hole size;

[0036] 2) Carry out preheating treatment on the blank processed by CNC lathe, and then carry out vacuum quenching and tempering to obtain the die part 1 with a hardness reaching HRC47~52 degrees;

[0037] 3) Carry out CNC machining on the die part 1 again, process the bottom surface 3 of the conical frustum of the die part and leave a machining allowance of 0.3mm, then process and remove the allowance of the inner hole part 2 and the outer dimension of the die part 1, and then Polishing the bore portion 2;

[0038] 4) After polishing, take the top surface 4 of the truncated cone of the concave mold 1 as the reference pl...

Embodiment 2

[0049] The processing method of the four-station die using H13 steel as a blank comprises the following steps:

[0050] 1) Carry out general car processing on the blank, and leave a machining allowance of 3 mm according to the final product size, and then process the inner hole part of the CNC lathe, and leave a machining allowance of 1 mm for the hole size;

[0051] 2) Carry out preheating treatment on the blank processed by CNC lathe, and then carry out vacuum quenching and tempering to obtain the die part 1 with a hardness reaching HRC47~52 degrees;

[0052] 3) Carry out CNC machining on the die part 1 again, process the bottom surface of the conical frustum of the die part and leave a machining allowance of 0.4mm, and then process and remove the allowance of the inner hole part 2 and the outer dimension of the die part 1, and then process the The inner hole part 2 is polished;

[0053] 4) After polishing, take the top surface 4 of the truncated cone of the concave mold 1 ...

Abstract

The invention discloses a processing method of a four-station concave die. The processing method comprises the following processing steps of processing an engine lathe, processing a numerical control lathe, preheating, vacuum quenching and tempering, processing the numerical control lathe again, fine processing and nitriding. Through the improvement and the addition of the technology steps of an original four-station concave die, the service life of the four-station concave die and the product comprehensive performance are greatly increased.

Description

technical field [0001] The invention relates to a processing method of a die, in particular to a processing method of a four-station die. Background technique [0002] With the development of national economy and industrialization, there are more and more manufacturers of hot forging dies processing shaft and hub products. In recent years, manufacturers of new products of various specifications have come out continuously, which has made the market supply demand of hot forging dies continuously increase. [0003] At present, the service life of the mold and the product quality have always been the key factors affecting this type of product. The service life and quality of the products processed by the previous mold production process have not been able to meet an ideal requirement. It brings inconvenience to the user, and the production cost of the user cannot be effectively controlled. The reason is that the number of mold changes cannot be reduced, more products cannot be...
