Abstract
The invention discloses a machining process of a tapered roller. The machining process includes the following steps of straightening and cutoff of wire rod materials, head grinding, stamping, ring belt stringing, soft grinding of external diameter, soft grinding of end faces, heat treatment, scale stringing, hard grinding of end face, coarse grinding of external diameter, fine grinding of external diameter, final grinding of external diameter, superfinishing of external diameter, cleaning and grading, and oiling and packing. By the machining process, machining efficiency and finished product rate are increased, production cost is lowered, the technical effect unexpected by technicians in the field is obtained, the longtime design set is overcome, a novel design and machining concept is provided, and the machining effect better than that in the prior art is obtained.
Description
Technical field
The present invention relates to the processing technique of a kind of taper roller.
Background technology
Taper roll bearing belongs to divergence type bearing, and the inside and outside circle of bearing is respectively provided with tapered raceway.This class bearing is divided into the different structural shapes such as single-row, biserial and four-row tapered roller bearing by the columns of filled roller.
Summary of the invention
Because the drawbacks described above of prior art, the technical problem to be solved is to provide the processing technique of a kind of taper roller, and this processing method is simple, eliminates a lot of repeatability operation, improves work efficiency.
For achieving the above object, the invention provides the processing technique of a kind of taper roller, comprise the steps, dish circle material alignment blocks → abrasive head → punching press → string annulus → buffing external diameter → buffing end face → heat treatment → string oxide skin → hard grind end face → corase grind external diameter → fine grinding external diameter → end grind external diameter → superfinishing external diameter → cleaning sort → oiling packs.
The invention has the beneficial effects as follows: technical scheme disclosed by the invention improves working (machining) efficiency, yield rate, reduce production cost, achieve the unforeseeable technique effect of those skilled in the art, overcome design set for a long time, provide a kind of new design and processing thought, and achieve more more preferable processing effect than prior art.
Detailed description of the invention
Technical scheme disclosed by the invention is the processing technique of a kind of taper roller, comprise the steps, dish circle material alignment blocks → abrasive head → punching press → string annulus → buffing external diameter → buffing end face → heat treatment → string oxide skin → hard grind end face → corase grind external diameter → fine grinding external diameter → end grind external diameter → superfinishing external diameter → cleaning sort → oiling packs.
Further, described Technology for Heating Processing comprises the steps, including normalizing process, uses nitrogen protection atmosphere and microcomputer carbon-potential control, and burner hearth forms the malleation of 1000Mpa-1100Mpa simultaneously, reaches the carbon potential of 1.00% and processes 2-3 hour in temperature 850-910 DEG C；Then carrying out quenching oil quenching, carry out cold treatment the most immediately, temperature is-30～-25 DEG C, after the cold treatment time is 260～300 minutes K cryogenic treatment, immediately entering a tempering stage, temperature is 160～170 DEG C, and temperature retention time is 180～250 minutes.
Technical scheme disclosed by the invention improves working (machining) efficiency, yield rate, reduce production cost, achieve the unforeseeable technique effect of those skilled in the art, overcome design set for a long time, provide a kind of new design and processing thought, and achieve more more preferable processing effect than prior art.
The preferred embodiment of the present invention described in detail above.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to the design of the present invention without creative work.Therefore, all technical staff in the art, all should be in the protection domain being defined in the patent claims the most on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment.
