Description

Technical Field

[0001] The invention relates to the technical field of stainless steel wire drawing equipment, in particular to a stainless steel wire drawing equipment and process for automobile springs. Background Art

[0002] Stainless steel wire drawing equipment for automobile springs is a general term for equipment that is specifically used to process stainless steel wire into the diameter and mechanical properties required by automobile springs through a drawing process. The equipment uses mechanical force to gradually draw the stainless steel wire from a larger diameter to the required small diameter while maintaining the uniformity and good physical properties of the wire. The equipment is widely used in automobile manufacturing, machinery manufacturing and other fields, and is used to produce automobile springs and other parts that require high-precision, high-strength stainless steel wire.

[0003] In the drawing process of the existing stainless steel wire drawing equipment for automobile springs, the stainless steel wire is fed into the drawing head, clamped by the clamping device and pushed forward. At the same time, the drawing die applies tension to the wire, allowing it to pass through the aperture of the die and gradually become thinner. The lubrication system provides the necessary lubrication for the drawing process to reduce friction and wear. The control system accurately controls the drawing process according to the set parameters to ensure that the drawn stainless steel wire meets the requirements of automobile springs.

[0004] However, the deformation of existing stainless steel wire for automobile springs needs to be strictly controlled during the drawing process. If the deformation is too large and exceeds the plastic deformation capacity of the material, it will cause wire breakage. Therefore, reasonable design and control of deformation is the key to preventing wire breakage. The lubrication system plays a vital role in the drawing process. If the lubrication is poor, such as improper lubricant selection, too thin lubricating coating or failure of lubricating fluid, the friction between the stainless steel wire and the die will increase, leading to temperature rise, die sticking and other problems, which will cause wire breakage. To reduce the problem of wire breakage in the drawing process, it is necessary to start from multiple aspects such as equipment structure design, process control, and equipment maintenance to ensure that each link reaches the optimal state.

The rotation of the second rotating shaft 507 will drive the dragon 508 to rotate. The rotation of the dragon 508 will push the coolant at the bottom end of the shell 200 to the upper end of the first sleeve 305. The coolant enters the upper end of the first sleeve 305 and overflows from the small holes on the surface of the bearing 304, so that the steel wire 303 can be accurately lubricated and cooled. Through the set structure, when the first motor 301 rotates, it will also drive the dragon 508 to rotate and push the coolant at the bottom end of the shell 200 to the upper end of the first sleeve 305. The coolant enters the upper end of the first sleeve 305 and overflows from the small holes on the surface of the bearing 304, so that the steel wire 303 can be accurately lubricated and cooled.

[0048] When the steel wire rope 303 is wound around the surfaces of multiple bearings 304, it is necessary to manually push the connecting tube 602 outward to move outward. The outward movement of the connecting tube 602 will drive the movable body 701 away from the bearings 304. When the connecting tube 602 moves outward, it will drive the sliding block 601 to move outward. The outward movement of the sliding block 601 will compress the compression spring 603 in the second sleeve 600. When the steel wire rope 303 is wound around the surfaces of multiple bearings 304, the compression spring 603 will drive the connecting tube 602 to reset. The reset of the connecting tube 602 will drive the movable body 701 to reset close to the bearings 304, and the movable body 701 will move away from the shaft The bearings 304 can conveniently wind the steel wire rope 303 around the surfaces of multiple bearings 304. The movable body 701 is reset close to the bearings 304 to better flush the steel wire 303. When the steel wire rope 303 is wound around the surfaces of multiple bearings 304, it is necessary to manually push the connecting tube 602 outward to move outward when the steel wire rope 303 is wound around the surfaces of multiple bearings 304. The outward movement of the connecting tube 602 will drive the movable body 701 away from the bearings 304. The movable body 701 is away from the bearings 304, which can facilitate winding the steel wire rope 303 around the surfaces of multiple bearings 304. The movable body 701 is reset close to the bearings 304 to better flush the steel wire 303.

[0049] When the dragon 508 rotates to push the coolant at the bottom of the shell 200 to the inside of the first sleeve 305, part of it will enter the connecting tube 602, and the connecting tube 602 will enter the movable body 701. The coolant in the movable body 701 will be discharged through the circular hole 702. The coolant discharged through the circular hole 702 will flush the steel wire 303. In this way, when the coolant is discharged through the circular hole 702 to flush the steel wire 303, it can not only cool and lubricate the steel wire 303, but also clean the debris produced by the drawing and grinding of the steel wire 303 through the circular hole 702, so as to avoid the surface of the steel wire 303 adhering to the debris for a long time. Chips affect drawing. A structure is set up so that when the dragon 508 rotates to push the coolant at the bottom of the shell 200 to the inside of the first sleeve 305, the coolant will also enter the movable body 701, and the coolant inside the movable body 701 will be discharged through the circular hole 702. The coolant discharged through the circular hole 702 will flush the steel wire 303. In this way, when the coolant is discharged through the circular hole 702 to flush the steel wire 303, it can both cool and lubricate the steel wire 303. The coolant discharged through the circular hole 702 can also clean up the chips produced by drawing on the steel wire 303, so as to avoid the chips adhering to the surface of the steel wire 303 for a long time and affecting the drawing.
