Description

Technical Field

[0001] This utility model belongs to the field of metal grinding and repair technology, and specifically relates to a control device for eliminating edge cracks in hot-rolled strip of stainless steel composite plate. Background Technology

[0002] During the production and rolling of hot-rolled stainless steel composite strip, the edges of the hot-rolled stainless steel composite strip cool down quickly, which makes the edges prone to cracking. It is necessary to grind and repair the edges of the hot-rolled stainless steel composite strip. However, although most existing technologies have grinding functions, the grinding rollers of the grinding devices cannot be adjusted, resulting in rapid local wear and short life of the grinding rollers. Furthermore, uneven grinding due to different plate thicknesses can affect the quality of the plate.

[0003] A search revealed that the prior art (CN222037915U) describes a device for preventing edge cracking of hot-rolled thin composite plates. This device includes a support frame, a grinding device, a cleaning device, and a heating device. The support frame is a pair, with several transport rollers rotatably connected to its inner side, and several ball bearings are provided in a mounting groove I on one side of the support frame. The grinding device is rotatably connected to the mounting groove I at both ends. The heating device is fixedly connected to the other side of the support frame, and the cleaning device is located between the grinding device and the heating device and fixedly connected to the support frame. However, this prior art grinding device cannot adjust the grinding rollers when grinding the edges of hot-rolled thin plates, causing the grinding rollers to grind the edges of the hot-rolled thin plates on a localized surface for an extended period. This results in increased localized wear and shortened lifespan of the grinding rollers, and uneven grinding due to variations in plate thickness also affects the quality of the plate.

[0004] Further search revealed that the prior art (CN218801055U) describes a composite board grinding device with a cleaning function, comprising a bracket mounted on the top of a workbench, a dust collection hood mounted on the bottom of the bracket, a collection box mounted on the top of the bracket, a vacuum cleaner mounted on the top of the bracket, and a hose mounted on one side of the vacuum cleaner. A first rotating rod is rotatably connected to the inner wall of the bracket, and a first grinding roller is mounted on the surface of the first rotating rod. A first gear is connected to the surface of the first rotating rod, and a first motor is mounted on one side of the bracket. While this prior art enables simultaneous grinding of three sides of the composite board, the grinding roller cannot be adjusted when grinding the sides of the composite board. This causes the local end face of the grinding roller to grind the edge of the hot-rolled thin plate for a long time, resulting in increased local wear and shortened lifespan of the grinding roller. Uneven grinding also affects the quality of the board. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a control device for eliminating edge cracking of hot-rolled strip of stainless steel composite plate. By cooperating with the adjustment mechanism and the side grinding mechanism, it not only solves the problem of the bulging of the middle of the hot-rolled strip of stainless steel composite plate when grinding the edge, but also solves the problem of the grinding roller's local end face grinding the edge of the hot-rolled thin plate for a long time, which leads to the local wear of the grinding roller being aggravated and the service life being shortened.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A control device for eliminating edge cracking of hot-rolled strip in stainless steel composite plate includes a transport frame, transport rollers, a fixed frame, an upper extrusion roller, a lower extrusion roller, an adjustment mechanism, and a side grinding mechanism.

A motor I is installed on one side of each of the upper and lower extrusion rollers. The adjustment mechanism and the side grinding mechanism are both mounted on the fixed frame. The adjustment mechanism is used to adjust the upper extrusion roller's extrusion of the hot-rolled strip to prevent bulging in the middle of the hot-rolled strip when the side grinding mechanism grinds the edge of the hot-rolled strip. The side grinding mechanism grinds and repairs edge cracks in the hot-rolled strip.

[0008] The adjustment mechanism includes an electric push rod and a sliding frame; the lower extrusion roller is rotatably mounted on the bottom of the fixed frame, and the upper extrusion roller is movably connected to the sliding frame through sliding grooves I at both ends of the fixed frame; the electric push rod is mounted on the top of the fixed frame, and telescopic rods I are provided on both sides of the fixed frame; the telescopic ends of the electric push rod and the telescopic ends of the telescopic rods I are both fixedly connected to the sliding frame.

The bidirectional lead screw and the sliding rod are located at the bottom of the fixed frame. The bidirectional lead screw is rotatably mounted to the fixed frame. One end of the bidirectional lead screw passes through the fixed frame and is fixedly connected to the output shaft of the motor II on one side of the mounting frame. The sliding rod is installed on both sides of the bidirectional lead screw. The bidirectional lead screw is provided with an accordion-style protective cover, which is sleeved on the bidirectional lead screw. One end of the accordion-style protective cover is fixed to the fixed frame, and the other end is fixedly connected to the sliding plate. There are two sets of sliding plates. The sliding plates are threadedly connected to the bidirectional lead screw and slidably connected to the sliding rod. The sliding plates are provided with a sliding groove II, and the upper and lower extrusion rollers are both located in the sliding groove II.

[0010] The sliding plate is provided with fixed plates on both sides, and the fixed plates are provided with sliding grooves III. The lead screw is rotatably installed on one side of the fixed plate, and a motor III is installed at one end of the lead screw. The output shaft of the motor III is fixedly connected to the lead screw. The sliding block is threadedly connected to the lead screw. The upper and lower ends of the sliding block are provided with telescopic protective sleeves, which are sleeved on the lead screw. The sliding block is slidably connected to the fixed plate through the sliding grooves III.

[0011] The sliding block is fixedly connected to the sliding shell. A mounting frame is slidably installed at one end of the sliding shell. Two sets of grinding rollers are rotatably installed on the mounting frame. A rotating shaft is provided between the two sets of grinding rollers.

A spring is sleeved on the outside of the telescopic rod II.

[0013] The bottom of the sliding shell is provided with several sets of suction ports.

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

[0015] 1) Motor II drives the bidirectional lead screw to rotate, causing two sets of sliding plates to move along the sliding rod, adjusting the spacing of the grinding rollers to adapt to hot-rolled strips of different widths; Motor III drives the lead screw to rotate, causing the sliding block to slide up and down along the sliding groove III of the fixed plate, adjusting the position of the grinding rollers, preventing the grinding rollers from grinding the edges of the hot-rolled thin plate on a localized end face for a long time, which would lead to increased localized wear and shortened lifespan of the grinding rollers; Through the dual dynamic adjustment of the spacing and position of the grinding rollers, the grinding rollers can be adapted to hot-rolled strips of different specifications while flexibly adjusting the position of the grinding rollers, avoiding excessive wear on the localized end faces of the grinding rollers, extending the service life of the grinding rollers, reducing maintenance costs, ensuring the uniformity of grinding, and effectively improving the edge processing quality and production efficiency of hot-rolled strips.

[0016] 2) The upper and lower extrusion rollers rotate, and the electric push rod drives the sliding frame to make the upper extrusion roller slide in the sliding groove I. Adjust the position of the upper extrusion roller to apply stable pressure to the middle of the hot-rolled strip, so as to prevent the side grinding mechanism from using too much force to grind the hot-rolled strip, causing the middle of the hot-rolled strip to bulge and damage the hot-rolled strip, and ensuring that the grinding and repair are carried out smoothly.

Detailed Implementation

[0024] To facilitate understanding by those skilled in the art, the following is in conjunction with the appendix. Figure 1-6 The technical solution of this utility model will be further described in detail below.

[0025] A control device for eliminating edge cracking of hot-rolled strip of stainless steel composite plate includes a transport frame 1, a transport roller 101, a fixed frame 102, an upper extrusion roller 103, a lower extrusion roller 104, an adjustment mechanism 2, and a side grinding mechanism 3. The transport frame 1 is equipped with several sets of transport rollers 101. The fixed frame 102 is installed on the transport frame 1 and is located between several sets of transport rollers 101. The upper extrusion roller 103 and the lower extrusion roller 104 are both installed on the fixed frame 102 and are arranged vertically and vertically. A motor I 105 is provided on one side of each of the upper extrusion roller 103 and the lower extrusion roller 104. The adjustment mechanism 2 and the side grinding mechanism 3 are both installed on the fixed frame 102. The adjustment mechanism 2 is used to adjust the upper extrusion roller 103 to extrude the hot-rolled strip to prevent the hot-rolled strip from bulging in the middle when the side grinding mechanism 3 grinds the edge of the hot-rolled strip. The side grinding mechanism 3 grinds and repairs the edge cracks of the hot-rolled strip.

[0026] As described above, the hot-rolled strip is conveyed by the transport roller 101 on the transport frame 1. After entering the area of ​​the fixed frame 102, the adjusting mechanism 2 adjusts the upper extrusion roller 103 to press against the middle of the strip to prevent the middle from bulging due to uneven force during grinding, thus ensuring a smooth grinding process. The side grinding mechanism 3 grinds and repairs the cracked edges of the hot-rolled strip, effectively repairing the cracks on the edges of the stainless steel composite plate hot-rolled strip and improving the quality of the stainless steel composite plate hot-rolled strip.

[0027] The adjustment mechanism 2 includes an electric push rod 23 and a sliding frame 25; the lower extrusion roller 104 is rotatably mounted on the bottom of the fixed frame 102, and the upper extrusion roller 103 is movably connected to the sliding frame 25 through the sliding grooves I 1021 at both ends of the fixed frame 102; the electric push rod 23 is mounted on the top of the fixed frame 102; telescopic rods I 24 are provided on both sides of the fixed frame 102; the telescopic ends of the electric push rod 23 and the telescopic ends of the telescopic rods I 24 are fixedly connected to the sliding frame 25.

[0028] As described above, the upper extrusion roller 103 and the lower extrusion roller 104 work together. The lower extrusion roller 104 is used for fixed support. The electric push rod 23 drives the sliding frame 25 to make the upper extrusion roller 103 slide in the sliding groove I 1021. The position of the upper extrusion roller 103 is adjusted to match the thickness of the hot-rolled strip of stainless steel composite plate. The motor I 105 on one side of the upper extrusion roller 103 and the lower extrusion roller 104 respectively drives the upper extrusion roller 103 and the lower extrusion roller 104 to rotate, applying stable pressure to the middle of the hot-rolled strip. This prevents the side grinding mechanism 3 from using too much force when grinding the hot-rolled strip, which would cause the middle of the hot-rolled strip to bulge and damage the strip, thus ensuring that the grinding and repair are carried out smoothly.

[0029] The side grinding mechanism 3 includes a motor II 31, a bidirectional lead screw 32, a sliding rod 33, a sliding plate 34, a lead screw 37, a motor III 39, a sliding block 310, a sliding shell 311, a mounting frame 312, a telescopic rod II 314, a motor IV 315, a grinding roller 318, and a connecting plate 319. The bidirectional lead screw 32 and the sliding rod 33 are located at the bottom of the fixed frame 102. The bidirectional lead screw 32 is rotatably mounted to the fixed frame 102, and one end of the bidirectional lead screw 32 passes through the fixed frame 102 and is fixed to the output shaft of the motor II 31 mounted on one side of the fixed frame 102. The connection is made by mounting sliding rods 33 on both sides of the bidirectional lead screw 32. The bidirectional lead screw 32 is provided with a bellows-type protective cover 35, which is sleeved on the bidirectional lead screw 32. One end of the bellows-type protective cover 35 is fixed to the fixed frame 102, and the other end is fixedly connected to the sliding plate 34. The sliding plate 34 is provided in two sets. The sliding plate 34 is threadedly connected to the bidirectional lead screw 32 and slidably connected to the sliding rod 33. The sliding plate 34 is provided with a sliding groove II 3401. The upper extrusion roller 103 and the lower extrusion roller 104 are both located in the sliding groove II 3401.

[0030] The sliding plate 34 is provided with fixed plates 36 on both sides. The fixed plates 36 are provided with sliding grooves Ⅲ3601. The lead screw 37 is rotatably installed on one side of the fixed plate 36. A motor Ⅲ39 is installed at one end of the lead screw 37. The output shaft of the motor Ⅲ39 is fixedly connected to the lead screw 37. The sliding block 310 is threadedly connected to the lead screw 37. The upper and lower ends of the sliding block 310 are provided with telescopic protective sleeves 38. The telescopic protective sleeves 38 are sleeved on the lead screw 37. The sliding block 310 is slidably connected to the fixed plate 36 through the sliding grooves Ⅲ3601.

[0031] The sliding block 310 is fixedly connected to the sliding shell 311. A mounting frame 312 is slidably installed at one end of the sliding shell 311. Two sets of grinding rollers 318 are rotatably installed on the mounting frame 312. A rotating shaft 317 is provided between the two sets of grinding rollers 318. The rotating shaft 317 is rotatably connected to the mounting frame 312. The top ends of the grinding rollers 318 and the rotating shaft 317 both pass through the mounting frame 312 and are located in the sliding groove IV 3111 of the sliding shell 311. The top ends of the grinding rollers 318 and the rotating shaft 317 are both provided with pulleys. The pulleys at the top ends of the grinding rollers 318 and the rotating shaft 317 are connected by belt drive. A protective shell is provided on the outside of the pulleys. The protective shell is slidably connected to the sliding shell 311. A motor IV 315 is installed at the top of the protective shell. The output shaft of the motor IV 315 passes through the protective shell and is fixedly connected to the rotating shaft 317.

[0032] A plurality of sets of telescopic rods II 314 are provided between the mounting frame 312 and the sliding shell 311. A connecting plate 319 is fixedly connected to one side of the mounting frame 312. The connecting plate 319 is fixedly connected to the telescopic end of the telescopic rod II 314. The connecting plate 319 is slidably connected to the sliding shell 311 through the telescopic rod II 314. A spring 313 is sleeved on the outside of the telescopic rod II 314.

[0033] The bottom of the sliding shell 311 is provided with several sets of suction ports 316;

[0034] As described above: Motor II 31 drives the bidirectional lead screw 37 to rotate, causing the two sets of sliding plates 34 to move along the sliding rod 33, adjusting the spacing of the grinding roller 318. The accordion-style protective cover 35 extends and retracts synchronously to adapt to hot-rolled strips of different widths. Motor III 39 drives the lead screw 37 to rotate, causing the sliding block 310 to slide up and down along the sliding groove III 3601 of the fixed plate 36. The telescopic protective sleeve 38 extends and retracts synchronously to prevent dust from adhering to the lead screw 37 and affecting its transmission. The sliding shell 311 and mounting bracket 312, which are fixedly connected to the sliding block 310, rise and fall with the sliding block 310, adjusting the grinding roller 318 to a suitable position and preventing localized damage to the grinding roller 318. Long-term grinding of the edges of hot-rolled thin plates leads to increased local wear and shortened lifespan of the grinding rollers 318. The motor IV 315 drives the rotating shaft 317, which, through the transmission of the pulley and belt, drives the two sets of grinding rollers 318 to rotate at high speed to grind and repair the cracks on the edges of the strip. The telescopic rod II 314, in conjunction with the outer spring 313, buffers the grinding rollers 318 when they contact the edges of the hot-rolled strip, preventing the grinding rollers 318 from hard-hitting and damaging the edges of the hot-rolled strip. The suction port 316 at the bottom of the sliding shell 311 promptly removes debris that enters the sliding shell 311, preventing debris from accumulating inside the sliding shell 311 and preventing the mounting bracket 312 from sliding inside the sliding shell 311.
