Abstract
The invention provides a start ratchet wheel and a processing technique thereof. The start ratchet wheel comprises a handle, wherein the front part of the handle is provided with a ratchet sleeve, a sleeve barrel is arranged in the ratchet sleeve, and the inner wall of the sleeve barrel is provided with teeth. The processing technique comprises the following steps: A, carrying out intermediate frequency heating on a 20CrMnTi material, then preparing the 20CrMnTi material subjected to intermediate frequency heating into a blank by utilizing a 100T punch, utilizing a 400T pressing machine to mold and extrude the blank to obtain the ratchet sleeve and the handle, carrying out tepefaction processing after trimming by utilizing a 80T punch, and forging the ratchet sleeve and the handle; B, hobbing the ratchet sleeve of the product obtained from the step A by utilizing a hobbing machine, thus obtaining the sleeve barrel with teeth; C, shaving the product obtained from the step B by utilizing a shaving machine; D, carrying out heat treatment on the product obtained from the step C by utilizing a continuous carburizing furnace; E. carrying out milling processing on the product obtained from the step D by utilizing an inner hole mill and a flat-stone mill; and F, cleaning the product obtained from the step E, painting preservative oil, and packing to obtain the finished product of the ratchet wheel. The start ratchet wheel has the advantages of simple structure, firmness and less material consumption, and is convenient to use; and the processing technique is simple.
Description
Technical field
The present invention relates to field of mechanical technique, particularly a kind of startup ratchet and processing technology thereof are used on the motorcycle initiating axle, play the motor centrifugation, are one of parts of clutch.
Background technique
The startup ratchet structure complexity that prior art provides, use inconveniently, also shaky, and the processing technology of the startup ratchet that provides of prior art is: round steel processing, car are washed, about consumptive material 600-700 gram, consuming time quite long, just be that the numerical control washing lotion is at least about 40 minutes.
Summary of the invention
The invention provides a kind of simple in structure, solid, easy to use and processing technology is simple, consumptive material is few startup ratchet and processing technology thereof.
To achieve these goals, the invention provides following technological scheme:
A kind of startup ratchet, it comprises handle, and the handle front portion is provided with ratchet sleeve, and is sleeved in the ratchet sleeve, and described sleeve lining is provided with tooth.
Preferably, described handle, ratchet sleeve and described sleeve are one-body molded.
The present invention also provides a kind of processing technology that starts ratchet, and it comprises step:
A, successively adopt 20CrMnTi material, heating in medium frequency, 100T punch press base, 400T press machine moulding extruding obtain ratchet sleeve and handle, again with carrying out warm processing after the side cut of 80T punch press, forging described ratchet sleeve and handle again;
The ratchet sleeve of B, the product that steps A obtained with gear hobbing machine carries out the sleeve that gear hobbing obtains having tooth;
C, the product that above-mentioned steps B obtains is carried out shaving with gear shaving machine;
D, the product that step C obtains is heat-treated with continuous acieration furnace;
E, endoporus mill and flat stone mill obtain product to step D and grind processing;
F, the product that step e is obtained clean rust preventive oil and are packaged to be finished product and start ratchet.

The embodiment of the invention also provides a kind of processing technology that starts ratchet, and it comprises step:
A, successively adopt 20CrMnTi material, heating in medium frequency, 100T punch press base, 400T press machine moulding extruding obtain ratchet sleeve and handle, again with carrying out warm processing after the side cut of 80T punch press, forging described ratchet sleeve and handle again;
The ratchet sleeve of B, the product that steps A obtained with gear hobbing machine carries out the sleeve that gear hobbing obtains having tooth;
C, the product that above-mentioned steps B obtains is carried out shaving with gear shaving machine;
D, the product that step C obtains is heat-treated with continuous acieration furnace;
E, endoporus mill and flat stone mill obtain product to step D and grind processing;
F, the product that step e is obtained clean rust preventive oil and are packaged to be finished product and start ratchet.
The technology that this processing technology processing starts ratchet is simple, consumptive material is few.The technology that present embodiment provides is used forging technology, no longer needs to wash, and a car is just passable, and the time only needed about 4 minutes, and consumptive material only needs gram more than 300, saves raw-material more than 1/2nd.
More than a kind of startup ratchet and processing technology thereof that the embodiment of the invention provided are described in detail, for one of ordinary skill in the art, thought according to the embodiment of the invention, part in specific embodiments and applications all can change, in sum, this description should not be construed as limitation of the present invention.
