It is believed that the spring will be familiar to you, because we can see it in our daily life, and you often play with it when you are a student, and now many machines will use it. We should not underestimate the small spring. Its advantage is very large. It can prolong the service life of the machine, and the vitality of the spring is also very high. If there are some heavy objects pressing on it, It will deform, but it will not be damaged. Only if the object is not pressed, it will change back to its original shape. I believe you must be curious about how to improve the quality of the spring. Let me tell you the following:
1. How to optimize the drawing process? When the number of equipment reels is under certain conditions, it is necessary to keep the total compression rate unchanged, properly reduce the partial compression rate, properly add the drawing times, especially reduce the partial compression rate of the terminal ground, which can change the internal stress distribution of the steel wire, so that the tensile strength continues to decline, the plastic target is rising, and the product qualification rate will be greatly improved.
2. During the drawing process, the sliding friction between the spring steel wire and the drawing die may lead to uneven deformation of the steel wire in the die hole, and a lot of heat energy will occur, adding energy consumption. At this time, the wire drawing powder needs to be dry and have good fluidity. During the drawing together, it also needs to be mixed frequently, so as to avoid coking of the wire drawing powder. During the drawing process, ensure that the cooling water channels of the die box and the drum are smooth, can adhere to the flow requirements, and insist that the die box is dry and clean. The drawing machine drum adopts internal narrow gap water cooling and external forced air cooling. The product drum adopts internal spray water cooling and external annular gap forced air cooling. The cooling water with relatively low hardness is used. The water pressure is 0.2-0.3mpa and the temperature should not exceed 30 ℃.
3. Three temperatures and one speed shall be strictly controlled during spring production;, It is necessary to control the lead temperature, furnace temperature, wire temperature and the running speed of steel wire in the furnace, so as to reduce the oxidation of the steel wire surface, prevent the steel wire from hanging lead, and strengthen the management of the lead tank to ensure that the surface of the lead liquid is covered tightly, so that the steel wire can cross run in the lead pot. In addition, it is also necessary to control broken ends and loose ends, and it is strictly forbidden to stop and go offline.
