Abstract
The invention relates to a machining process for a disc spring used for a forging press. The machining process is characterized in that round steel is blanked, upsetting operation and drawing-out forging operation are conducted at least four times, after the steel is annealed, the outer round face is turned, holes are drilled, the steel is turned and sliced, the two end faces of each piece are ground and deburred, and cold pressing forming is conducted on each piece on a cold pressing forming die; each piece is quenched, each piece is tempered in a die clamping state and air-cooled to the normal temperature after being tempered, and a product is checked and put in storage after the die is detached. According to the machining process, the process procedure is reasonable, the structural strength and the fatigue resistance of the disc spring are improved, the service life of the disc spring is prolonged, the halt repair time of the forging press is shortened, production efficiency is improved, the workload of workers is reduced, and the labor intensity of the workers is lowered.
Description
Technical field
The present invention relates to a kind of processing technology of spring, especially relate to a kind of processing technology of forging press disk spring.
Background technology
Forging press adopts disk spring device to carry out discharging to forging mostly, this disk spring usually adopts steel spring plate to make or processes by 60Si2MnA round steel annealing rear car, and technological process is through blanking → annealing → car outer diameter face → brill endoporus → section → grinding two end face → deburring → cold-press moulding → quenching → tempering.Because this kind of disk-shape spring structure is simple, processing technology is simple, low cost of manufacture.But; without forging processing in the processing technology of disk spring; have streamline distribution unreasonable; the internal flaws such as institutional framework is fine and closely woven not; and it is large to there is deflection when disk spring shapes; fatigue strength is lower; cause disk spring of poor quality, the problem that service life is shorter, in large batch of bearing ring forging process; forging press cannot long time continuous working; need frequent shutdown to keep in repair, change disk spring, reduce production efficiency; increase the workload of workman, increase the labour intensity of workman.
Summary of the invention
The applicant is for above-mentioned problem; be studied improvement; a kind of processing technology of forging press disk spring is provided; improve structural strength and the fatigue resistance of disk spring; extend disk spring service life, reduce forging press fault power time, enhance productivity; reduce the workload of workman, reduce the labour intensity of workman.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme:
A processing technology for forging press disk spring, with the blanking of 60Si2MnA round steel, carries out at least 4 jumping-ups, pullings and forges, annealing rear car periphery also bores endoporus, car cutting sheet, removes burr, cold-press moulding on cold-press moulding mould after every a slice grinding both ends of the surface; Quenching, and tempering under mold cramping state, after tempering, air cooling is to normal temperature, inspection warehouse-in after dismounting mould.
Further:
Described quenching process is carried out in batch-type furnace, and entering stokehold needs at disk spring uniformly brushing antioxidizing paint, and hardening heat is 850 ~ 890 ° of C, and the time at 8 ~ 12 minutes, and adopts oil quenching.
Described temperature is 450 ~ 490 ° of C, the time at 2.5 ~ 4 hours, air cooling after tempering.
Technique effect of the present invention is:
The processing technology of a kind of forging press disk spring disclosed by the invention; technological process is reasonable; improve structural strength and the fatigue resistance of disk spring; extend disk spring service life; reduce forging press fault power time; enhance productivity, reduce the workload of workman, reduce the labour intensity of workman.
Detailed description of the invention
Below the specific embodiment of the present invention is described in further detail.
With the blanking of 60Si2MnA round steel, carry out 6 jumping-ups, pullings and forge, annealing rear car periphery also bores endoporus, car cutting sheet, remove burr, cold-press moulding on cold-press moulding mould after every a slice grinding both ends of the surface, cold-press moulding Die Cone Angle should be larger than the cone angle of disk spring 30 ' ~ 1 °; Quench after shaping, quenching process is carried out in batch-type furnace, and entering stokehold needs at disk spring uniformly brushing antioxidizing paint, and hardening heat is 850 ~ 890 ° of C, and the time at 8 ~ 12 minutes, and adopts oil quenching mode; Carry out tempering after quenching, disk spring is stacked piecewise and by mold cramping, Die Cone Angle should be larger than the cone angle of disk spring 30 ' ~ 1 °, tempering under mold cramping state, temperature is 450 ~ 490 ° of C, and the time was at 2.5 ~ 4 hours, after tempering, air cooling is to normal temperature, inspection warehouse-in after dismounting mould.
