Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of stainless steel wire polishing, in particular to a polishing device for stainless steel wire processing and production. BACKGROUND

[0002] As one of the four core varieties of steel plates, pipes, profiles and wires, stainless steel wire is a key reprocessed product processed by hot rolling wire rod through cold drawing process. It has outstanding corrosion resistance and can work stably in harsh chemical environments such as acid and alkali, so it is widely used in papermaking industry scenes that need to contact chemicals, and also widely used in many industrial fields such as rope making, spring and structural parts, which is an important basic component supporting industrial production.

[0003] However, after the stainless steel wire is drawn into shape, burrs will inevitably remain on the surface. Due to the particularity of the thin diameter of the steel wire and the curved surface structure of the outer surface, there are many technical defects in the traditional polishing method that are difficult to overcome in actual operation: first, impurities attached to the surface of the polishing belt or polishing disc cannot be removed in real time during the traditional polishing process. As the polishing operation continues, impurities will continue to accumulate and cause the surface roughness of the polishing belt to decrease significantly, directly causing poor polishing effect of the steel wire and failing to meet the requirements of industrial production on the surface quality of the steel wire; second, the traditional polishing device usually uses the same position of the polishing belt or polishing disc to polish the steel wire. Continuous friction in the local area will gradually increase the temperature of the polishing belt or polishing disc and cause it to deteriorate, significantly shortening its service life and increasing the cost of enterprise production materials; third, the traditional polishing device can only process burrs on newly drawn steel wires, and cannot effectively polish steel wires with rust, dirt and other impurities attached to their surfaces, which limits the application range of the device and makes it difficult to meet the production needs of the whole cycle of new and old steel wires.

One skilled in the art will recognize that some aspects of the embodiments described below can be used in other embodiments without departing from the scope of the present application.

[0019] Referring to Figures 1-8 In the embodiments of the present application, a polishing device for stainless steel wire processing and production includes a base plate 1 and two one-way wheels 2, the two one-way wheels 2 are respectively installed on the left and right ends of the upper surface of the base plate 1, the one-way wheels 2 play a limiting role on the steel wire, a tensioning mechanism 3 is installed on the middle of the upper surface of the base plate 1, two polishing mechanisms 4 that are symmetrical in front and back are installed on the top of the tensioning mechanism 3, a rotating mechanism 5 is installed on the right side wall of the polishing mechanism 4, the rotating mechanism 5 is used to drive the polishing mechanism 4 to run, the tensioning mechanism 3 provides tension for the polishing mechanism 4, so that the polishing mechanism 4 polishes the steel wire, and a knocking mechanism 6 is installed on the left side wall of the polishing mechanism 4.

When the handle 37 is rotated counterclockwise, the first rotating disc 36 drives the connecting rod 38 to rotate counterclockwise, and the connecting rod 38 pulls the polishing mechanism 4 to move inward, which facilitates the installation of the polishing mechanism 4 on the steel wire for polishing work.

[0021] Further, the polishing mechanism 4 comprises a shell 41 installed on the upper surface of the sliding block 33, the inner side of the shell 41 is provided with a second rotating shaft 42 at the upper and lower ends through bearings, the left and right sides of the outer wall of the second rotating shaft 42 are respectively provided with a winding drum 43 and a first spur gear 44, one end of the winding drum 43 is rotatably provided with a clamping plate 45 through a hinge, the other end of the clamping plate 45 is screwed with a screw 46, the winding drum 43 is clamped with a polishing belt 47 through the clamping plate 45, and the polishing belt 47 is fixed when the screw 46 is threadedly engaged with the winding drum 43, the winding drum 43 is rotated to wind and release the polishing belt 47, so that the polishing belt 47 is steel wire polished, the polishing belt 47 is uniformly stressed, the polishing belt 47 is cooled, the service life is prolonged, and the mechanical vibration caused by the steel wire can make the impurities on the surface of the polishing belt 47 fall off, so that the polishing belt 47 maintains excellent polishing effect. Since the polishing belt 47 is always in a dynamic moving state, and is not fixed at a single position and rubbed with the steel wire, on the one hand, the stress of the polishing belt 47 is uniformly distributed along the length direction, avoiding the local area from being abraded due to excessive friction; on the other hand, the heat generated by the friction between the polishing belt 47 and the steel wire is quickly dispersed with the movement, reducing the accumulation of heat in the local area, effectively preventing the polishing belt 47 from being deteriorated due to high temperature, and at the same time, the friction between the polishing belt 47 and the surface of the steel wire and the slight mechanical vibration caused by the rotation of the winding drum 43 can make the steel wire scraps, burrs and impurities attached to the surface of the polishing belt 47 automatically fall off, avoiding the roughness of the surface of the polishing belt 47 from being reduced due to the accumulation of impurities.

[0022] Further, the rotating mechanism 5 comprises a first box body 51 installed on the right side wall of the shell 41, a third rotating shaft 52 is installed on the inner side of the first box body 51 through a bearing, the left and right ends of the outer wall of the third rotating shaft 52 are respectively provided with one end of a support rod 53, the other end of the support rod 53 is provided with a sliding rod 54, the third rotating shaft 52 and the sliding rod 54 are connected through the support rod 53 to realize linkage, when the sliding rod 54 swings up and down, the third rotating shaft 52 rotates clockwise and counterclockwise, providing power for the movement of the polishing belt 47, the left end of the third rotating shaft 52 extends to the inner side of the shell 41 and is provided with a second spur gear 55, and the second spur gear 55 is meshed and connected with the first spur gear 44 to drive the two first spur gears 44 to rotate synchronously, and the rear middle part of the first box body 51 is provided with a driving assembly 56.

The sliding rod 54 provides a horizontal movement space for the plug rod 563, so that when the motor 561 drives the plug rod 563 to rotate, the plug rod 563 slides on the sliding rod 54 while the sliding rod 54 moves up and down, and the plug rod 563 can also stretch and contract on the rotating rod 562, so as to adapt to the distance change between the sliding rod 54 and the rotating rod 562.

Under the action of the tension of the tension spring 69, the pressing rod 67 is pulled upward; By loosening the shaft coupling, the fourth rotating shaft 62 can be separated from the second rotating shaft 42 to realize the deburring operation of the new steel wire.

[0025] Further, the outer side of the pressing plate 64 is arc-shaped, and the two sides are concave. With the rotation of the second turntable 63 driving the pressing plate 64, the curved surface of the pressing plate 64 can press the pressing rod 67 downward, so as to make the swing rod 66 swing upward to store energy. At the moment when the pressing plate 64 and the pressing rod 67 are separated, because the pressing plate 64 is concave, the pressing plate 64 will not hinder the pressing rod 67 from swinging upward rapidly, so that the knocking rod 68 has enough power to knock the steel wire.
