Abstract
The manufacture craft of the open trunk brake drum of the present invention safety loop, it is characterized in that comprising the steps: (1) first get 30mm-60mm wide × the thick low charcoal alloy-steel plate of 8mm is as the material of making safety loop, and length is according to brake drum size diameter Len req; (2) material of step (1) is carried out to cold rolling, volume circle by self-control cold-rolling mill, then weld and make the each kind required size of brake drum safety loop with gas-shielded welder; (3) after finally safety loop made step (2) being 400-600 degree Celsius by heating heating by electric cooker to temperature, again safety loop is assembled on brake drum, can obtain the raw product of trunk brake drum safety loop, this technique is made simple, the product of making flexible, the long service life of expanding with heat and contract with cold, and can not rupture under chilling, anxious hot state.
Description
Technical field
The present invention relates to the processing method of automobile braking parts, particularly the manufacture craft of trunk brake drum safety loop.
Background technology
Current rapid economic development be unable to do without automobile, and automobile is the main means of transport in land. In brake system of car, the quality of each parts directly affects the security of operation of automobile. Automobile brake drum is to adopt casting pig casting to form at present, and gray cast iron material characteristic is indeformable, heat conduction is fast, but easily cracked, in automobilism, brake drum is the part of undertaking retarding braking, in retarding braking process, brake drum is bearing under high pressure, high temperature and anxious heat, chilling working condition, and in automobilism, brake drum is easy to crack, once brake drum cracking produces brake failure and causes the unsafe accident of automobilism. Easily cause problem of Cracking in order to solve because brake drum produces high pressure, high temperature and anxious heat, chilling in the time braking, we install special steel safety loop additional and solve on brake drum reinforcement mouth.
Summary of the invention
In order to overcome above shortcomings part in prior art, the object of the present invention is to provide a kind of manufacture craft of trunk brake drum safety loop, this technique is made simple, the product of making flexible, the long service life of expanding with heat and contract with cold, and can not rupture under chilling, anxious hot state.
In order to reach above-mentioned object, the present invention adopts following concrete technical scheme: the manufacture craft of trunk brake drum safety loop, is characterized in that comprising the steps:
First get 30mm-60mm wide × the thick low charcoal alloy-steel plate of 8mm is as the material of making safety loop, and length is according to brake drum size diameter Len req;
By stepMaterial carry out cold rolling, volume circle by self-control cold-rolling mill, then make the each kind required size of brake drum safety loop with gas-shielded welder welding;
Finally by stepAfter made safety loop is 400-600 degree by heating heating by electric cooker to temperature, then safety loop is assembled on brake drum, can obtains the raw product of trunk brake drum safety loop.
Compared with prior art, the present invention has following outstanding advantages and effect:
1. brake drum safety loop is made by low charcoal steel alloy, and this strength of materials is high expands with heat and contract with cold flexiblely, and it can not rupture under chilling, anxious hot state;
2. ensureing that automobile is in operation produces brake failure can not break because of brake drum time, ensure vehicle operational safety, substantially prevented in automobilism because of brake drum break generation accident, ensure vehicle operational safety, extended the service life of brake drum;
3. in car running process, if brake drum has slight slight crack safety loop to play a protective role, allow driver or repairman have more time and chance to go to find and convert it, get rid of to greatest extent potential safety hazard.
4., when brake drum ftractures suddenly, safety loop has played protective effect, being difficult for splinter of use and cause brake system Its Failures or cause miscellaneous part damage, thereby ensured traffic safety.
Detailed description of the invention
In order further to explain technical scheme of the present invention, below by specific embodiment, the present invention will be described in detail.
The manufacture craft of trunk brake drum safety loop, is characterized in that comprising the steps:
First get 30mm-60mm wide × the thick low charcoal alloy-steel plate of 8mm is as the material of making safety loop, and length is according to brake drum size diameter Len req;
By stepMaterial carry out cold rolling, volume circle by self-control cold-rolling mill, then make the each kind required size of brake drum safety loop with gas-shielded welder welding;
Finally by stepThe principle that made safety loop utilization is expanded with heat and contract with cold, after being 400-600 degree, then is assembled to safety loop on brake drum by heating heating by electric cooker to temperature, can obtain the raw product of trunk brake drum safety loop.
Finally it should be noted that: above embodiment is only unrestricted in order to technical scheme of the present invention to be described, although the present invention is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement technical scheme of the present invention, and not departing from the spirit and scope of technical solution of the present invention, it all should be encompassed in the middle of claim scope of the present invention.
