Description

Technical Field

[0001] This utility model belongs to the field of pickling technology for stainless steel composite plate coils, and specifically relates to a device for descaling stainless steel composite plate coils after annealing. Background Technology

[0002] To improve the pickling efficiency of hot-rolled strip steel, the surface of the hot-rolled strip steel is usually descaled before pickling. The tension leveler is a key piece of equipment for removing iron oxide scale from the surface of the strip steel, and it can also improve the shape of the strip steel.

[0003] A search revealed a scale breaking and straightening machine with the existing technology announcement number CN209318445U; it includes a frame and a bending unit mounted on the frame. The bending unit includes an upper bending roller group and a lower bending roller group. The upper bending roller group includes an upper bending roller seat and two or more upper bending roller systems, which are all mounted on the upper bending roller seat and arranged at intervals along the strip passing line. The lower bending roller group is located below the upper bending roller group and includes a lower bending roller seat and two or more lower bending roller systems, which are arranged alternately with the two or more upper bending roller systems, and both of the lower bending roller systems are mounted on the lower bending roller seat.

[0004] A search revealed an adjustable wrap angle stretch bending straightening machine with existing technology announcement number CN111229835B, comprising a steering roller, an inlet tension roller group, a roller distance scale, a roller distance moving screw cover, a lower roller distance moving mechanism, a protective cover, an outlet tension roller group, a lower roller distance moving mechanism, an upper roller distance moving mechanism, a roller distance indicator, a wedge, a central connecting column, a frame, a lifting platform, a lifting platform motor, and a lifting synchronous connecting rod. The steering roller, inlet tension roller group, first bending roller, intermediate bending roller, straightening roller, and outlet tension roller group are arranged sequentially according to the direction of strip steel running. The lower part of the first bending roller, intermediate bending roller, and straightening roller is equipped with a roller distance moving screw cover and a roller distance scale, and the upper part is equipped with a roller distance indicator.

[0005] The above-mentioned patented processing method has the following disadvantages: During the bending process of the strip steel, the oxide scale on the surface of the strip steel adheres to the surface of the working roll in the bending roll group, which will cause wear between the working roll and the support roll, and further cause wear on the surfaces of the working roll and the support roll, resulting in gaps between the working roll and the support roll; it will reduce the support effect of the support roll on the working roll, thereby affecting the bending and straightening effect of the working roll on the steel strip. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a tension leveling and descaling device for stainless steel composite plate coils after annealing. The cleaning mechanism can reduce the wear between the working roller and the support roller, increase the service life of the working roller and the support roller, and improve the descaling quality of stainless steel composite plate coils.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A descaling device for stainless steel composite plate coils after annealing includes a housing, an inlet, an outlet, a descaling mechanism, a cleaning mechanism, and conveying rollers. The inlet and outlet are located at opposite ends of the housing. The descaling mechanism is installed inside the housing, the cleaning mechanism is installed on the descaling mechanism, and the conveying rollers are installed on both sides of the housing. The stainless steel composite plate enters the housing through the inlet, and then undergoes descaling through the descaling mechanism to break the oxide scale on the surface of the stainless steel composite plate. Finally, it is transported out through the outlet.

[0009] The descaling mechanism consists of two sets, located on the upper and lower sides of the stainless steel composite coil, respectively. Each descaling mechanism includes a mounting frame, support rollers, working rollers, electric push rods I, and a mounting box. Several electric push rods I are provided, all fixed to the top of the box. The mounting frame is installed inside the box and connected to the output end of the electric push rods I. The mounting box is movably connected inside the mounting frame. A pair of support rollers are rotatably connected to the mounting frame via bearings. The working roller is rotatably connected to the mounting box below the support rollers, with its surface in contact with the support roller surface. When the stainless steel composite coil passes through the descaling mechanism, the electric push rods I provide power, simultaneously moving the mounting frame, support rollers, and working rollers up and down. This causes the working rollers to bend the stainless steel composite coil, further achieving tension straightening and descaling of the stainless steel composite coil, which is beneficial for pickling the stainless steel composite coil.

[0010] The cleaning mechanism includes a support plate, an electric push rod II, a scraper, and a collection box. The support plate is fixed to the side wall of the mounting box, the electric push rod II is fixed to the end of the support plate away from the mounting box, the scraper is connected to the output end of the electric push rod II, and the scraper blade is in contact with the surface of the work roller. The collection box is fixed to the electric push rod II below the scraper, and the end of the negative pressure suction pipe is connected to the side wall of the collection box. During the rotation of the work roller, the electric push rod II provides power to drive the scraper to move. The scraper blade contacts the work roller, causing the scraper to scrape off the impurities adhering to the surface of the work roller. The scraped impurities fall into the collection box and are then collected and discharged through the negative pressure suction pipe. The cleaning mechanism can reduce the wear between the work roller and the support roller, increase the service life of the work roller and the support roller, and improve the descaling quality of the stainless steel composite coil.

[0011] The output end of the electric push rod II is provided with a support block, and the support block has an installation groove inside. The scraper has a movable plate on its side wall near the electric push rod II. The movable plate is connected to the installation groove inside the support block. The two ends of the spring are fixed to the support block and the movable plate respectively. The collection box is fixed on the support block. The elastic force of the spring can make the movable plate drive the scraper to always be in contact with the surface of the work roller, preventing the scraper from wearing away from the work roller after long-term use, which would further prevent the scraper from being able to scrape off the impurities adhering to the surface of the work roller.

[0012] The mounting frame is equipped with an adjustment mechanism, which includes a lead screw, a connecting plate, a motor, and a guide rod. The mounting frame has guide grooves at both ends. One end of the connecting plate is movably connected inside the guide groove. Both ends of the lead screw are rotatably connected to the mounting frame via bearings. The guide rod is fixed to the end of the mounting frame away from the lead screw. A pair of connecting plates are provided, each connected to the lead screw and the guide rod respectively. The other end of the connecting plate is fixed to the side wall of the mounting box. The working roller and the support roller are connected to the mounting box. The motor is fixed to the top of the mounting frame, and its output end is connected to one end of the lead screw. The motor provides power to drive the lead screw to rotate. The lead screw, through a thread, drives the connecting plate to move along the guide groove of the mounting frame, thereby enabling fine adjustment of the height of the working roller and the support roller to accommodate stainless steel composite coils of different thicknesses.

[0013] An arc-shaped baffle is provided on the mounting box below the stainless steel composite coil. The arc-shaped baffle is located above the work roller. It can prevent the scraped oxide scale from falling between the support roller and the work roller, as well as between the support roller and the mounting box, thereby increasing the wear of the support roller.

[0014] The advantages of this utility model compared with the prior art are as follows:

[0015] 1) When the stainless steel composite coil passes through the descaling mechanism, the electric push rod I provides power and drives the mounting frame, support roller, and working roller to move up and down; thereby causing the working roller to bend the stainless steel composite coil; further realizing the tension straightening and descaling of the stainless steel composite coil; which is beneficial to the pickling of the stainless steel composite coil.

[0016] 2) During the rotation of the work roll, the electric push rod II provides power to drive the scraper to move. The scraper blade contacts the work roll, causing the scraper to scrape off the impurities adhering to the surface of the work roll. The scraped impurities fall into the collection box and are then collected and discharged through the negative pressure suction pipe. This cleaning mechanism can reduce the wear between the work roll and the support roll, increase the service life of the work roll and the support roll, and improve the descaling quality of the stainless steel composite coil.

[0017] 3) The spring force enables the moving plate to drive the scraper to always keep it in contact with the surface of the work roller, preventing the scraper from wearing away from the work roller after long-term use, which would further prevent the scraper from scraping off the impurities adhering to the surface of the work roller.

The scraped impurities fall into the collection box 504 and are then collected and discharged from the cleaning mechanism 5 through the negative pressure suction pipe 505. This can reduce the wear between the working roller 402 and the support roller 403, increase the service life of the working roller 402 and the support roller 403, and improve the tensile leveling and descaling quality of the stainless steel composite coil 7.

The elastic force of the spring 506 enables the movable plate 5031 to drive the scraper 503 to always be in contact with the surface of the work roller 402, preventing the scraper 503 from wearing away from the work roller 402 after long-term use, which would further prevent the scraper 503 from being able to scrape off the impurities adhering to the surface of the work roller 402.
