Abstract
The invention discloses a manufacturing process of brake drum safety loops of heavy trucks. The manufacturing process is characterized by selecting a low-carbon alloy steel plate with the width of 30mm to 60mm and the thickness of 8mm as a material for manufacturing the safety loops, wherein the length of the steel plate is defined according to the needed sizes and diameters of brake drums; and the manufacturing process is also characterized by comprising the following steps of: performing cold rolling and coiling on the material through a self-cold rolling mill; welding the material by a gas welding machine to form the safety loops with the sizes meeting the requirements on the sizes of the various brake drums; and finally, heating the safety loops to 400-600 DEG C by a heating electric furnace and assembling the safety loops on the brake drums, thus obtaining the brake drum safety loops of the heavy trucks. The manufacturing process disclosed by the invention is simple, and the manufactured product has the advantages of good flexibility of expanding with heat and contracting with cold and long service life and is prevented from being cracked at quenching and quick heating states.
Description
Technical field
The present invention relates to the processing method of motor vehicle braking parts, particularly the manufacture craft of truck 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.The quality of each parts directly influences the security of operation of automobile in the brake system of car.Automobile brake drum is to adopt the casting pig casting to form at present; And the gray cast iron material characteristic is indeformable, and heat conduction is fast, but is prone to cracked; Brake drum is a part of undertaking retarding braking in automobilism; Brake drum is bearing under high pressure, high temperature and anxious heat, the chilling working condition in the retarding braking process, and brake drum is easy to crack in the automobilism, and brake drum in a single day cracking produces brake failure and causes the unsafe accident of automobilism.Be prone to cause the cracking problem in order to solve because of brake drum produces high pressure, high temperature and anxious heat, chilling when braking, we install special steel safety loop additional and solve on brake drum reinforcement mouth.
Summary of the invention
In order to overcome the above-mentioned weak point that exists in the prior art; The object of the present invention is to provide a kind of manufacture craft of truck brake drum safety loop; This technology is made simple, the product of making flexible good, the long service life of expanding with heat and contract with cold, and under chilling, anxious hot state, can not rupture.
In order to reach above-mentioned purpose, the present invention adopts following concrete technical scheme: the manufacture craft of truck brake drum safety loop is characterized in that comprising the steps:
The thick low charcoal alloy-steel plate of
at first gets 30mm-60mm wide * 8mm is as the material of making safety loop, and length is according to brake drum size diameter Len req;
at last that step
is made safety loop is heated to after temperature is the 400-600 degree through adding electrothermal stove; Again safety loop is assembled on the brake drum, can obtains truck brake drum safety loop and give birth to article.
Compared with prior art, the present invention has following outstanding advantage and effect:
1. the brake drum safety loop is made by low charcoal steel alloy, and this strength of materials height expands with heat and contract with cold flexible good, and it can not rupture under chilling, anxious hot state;
2. guaranteeing that automobile is in operation in the time of can not breaking because of brake drum produces brake failure, guarantees vehicle operational safety, has prevented basically in the automobilism to guarantee vehicle operational safety because of the brake drum institute's generation accident of breaking, and has prolonged the service life of brake drum;
3. in car running process,, let driver or repairman have more time and chance to go to find and convert it, get rid of potential safety hazard to greatest extent if brake drum has slight slight crack safety loop to play a protective role.
4. when brake drum ftractureed suddenly, safety loop had played protective effect, being difficult for splinter of use and cause the malfunctioning problem of brake system or cause miscellaneous part to damage, thus guaranteed traffic safety.
The specific embodiment
In order further to explain technical scheme of the present invention, come the present invention is set forth in detail through specific embodiment below.
The manufacture craft of truck brake drum safety loop is characterized in that comprising the steps:
The thick low charcoal alloy-steel plate of
at first gets 30mm-60mm wide * 8mm is as the material of making safety loop, and length is according to brake drum size diameter Len req;
The principle that
expands with heat and contract with cold the made safety loop utilization of step
at last; Be heated to after temperature is the 400-600 degree through adding electrothermal stove; Again safety loop is assembled on the brake drum, can obtains truck brake drum safety loop and give birth to article.
What should explain at last is: above embodiment is only unrestricted in order to technical scheme of the present invention to be described; Although the present invention is specified with reference to preferred embodiment; Those of ordinary skill in the art is to be understood that; Can make amendment or be equal to replacement technical scheme of the present invention, and not break away from the spirit and the scope of technical scheme of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
