Description

Technical Field

[0001] This invention belongs to the field of steel strip trimming technology, specifically, it relates to a steel strip trimming device for cold rolling of stainless steel strip. Background Technology

[0002] In the field of stainless steel strip cold rolling, strip trimming equipment is a key piece of equipment to ensure product quality and production efficiency. Most existing stainless steel strip cold rolling strip trimming equipment can well meet the trimming requirements of steel strips of conventional thickness (especially thinner ones). Through the cooperation of cutting components and guiding structures, stable cutting and edge treatment of thin steel strips can be achieved, which to a certain extent ensures the continuity of production and the appearance quality of products.

[0003] However, with the increasing demands on the performance of stainless steel strips in industrial applications, the use of thicker stainless steel strips is becoming more and more widespread. When using traditional edge-cutting devices to cut thicker steel strips, due to the high hardness and toughness of the thick steel strips, a large number of burrs are easily generated on the cut surface during the cutting process, and a large amount of debris is produced. This debris not only adheres to the surface of the steel strip, increasing the difficulty of cleaning, but also results in a slow cutting speed and a significant reduction in production efficiency due to the larger cutting depth required for thick steel strips.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0010] The substrate is equipped with a first guide roller and a second guide roller that rotate synchronously. The first guide roller is used to guide the cut steel strip to slide onto the friction plate for grinding, and the second guide roller is used to guide the ground steel strip and waste material to move to the water tank installed on the workbench surface for cleaning. The second guide roller is also used to guide the cut waste material to move downwards and cooperate with the upward-moving steel strip to generate shearing force at the cutting position.

[0011] The workbench is also equipped with a limiting roller for adjusting the tension of the waste strip after cutting.

[0012] In a preferred embodiment of the present invention, the bottom of the workbench is equipped with four support legs, and the adjacent support legs are equipped with reinforcing ribs. The heights of the adjacent reinforcing ribs are different to reduce excessive local stress. The bottom of the base plate is equipped with a base, which is in the shape of a boss and is connected to the workbench by bolts.

[0013] In a preferred embodiment of the present invention, positioning plates are installed at both ends of the roller, and the diameter of the positioning plates is larger than that of the roller. A drive shaft is installed at the rotation center of the positioning plates. The drive shaft movably passes through the base. A drive motor is installed at the end of the drive shaft. The housing of the drive motor is installed on the base plate. A cutting slit is opened on the roller, and the cutting slit is vertically corresponding to the cutting blade.

[0014] In a preferred embodiment of the present invention, a plurality of pairs of ball bearings are installed on the top plate, and a positioning rod is installed at the other end of the top plate. A positioning cover is inserted into the positioning rod and installed on the side wall of the base plate. A baffle is slidably arranged inside the positioning cover. One end of the baffle is connected to the positioning rod, and a compression spring is engaged between the other end of the baffle and the inner wall of the positioning cover. The compression direction of the compression spring and the movement direction of the positioning rod are both on the same straight line.

[0015] In a preferred embodiment of the present invention, a cutting motor is mounted on the rotation center of the cutting blade, a connecting frame is mounted on the housing of the cutting motor, the output shaft of the cutting motor is rotatably connected to the connecting frame, and a positioning seat is mounted on the side wall of the connecting frame. A pressure roller is mounted on the positioning seat, the pressure roller is adapted to the first guide roller, and the pressure roller is located above the first guide roller. The pressure roller and the first guide roller are used to position the steel strip to be ground.

[0016] In a preferred embodiment of the present invention, an electric push rod is installed on the connecting frame. The electric push rod is used to position the cutting blade. A mounting bracket is installed at the output end of the electric push rod. The mounting bracket is L-shaped. The side wall of the mounting bracket is connected to the substrate. An inclined plate is installed at the bend of the mounting bracket.

[0017] In a preferred embodiment of the present invention, a positioning frame is installed at the center of the first guide roller and the second guide roller, a synchronous shaft is installed through the positioning frame, the synchronous shaft movably passes through the substrate, a flip motor is installed at the end of the synchronous shaft, and the housing of the flip motor is installed on the side wall of the substrate.

[0018] In a preferred embodiment of the present invention, a first sleeve is sleeved at one end of the synchronous shaft, the bottom of the first sleeve is in contact with the waste strip, a second sleeve is sleeved at the center of the synchronous shaft, the bottom of the second sleeve is in contact with the cut steel strip, and the cut steel strip is in contact with the lower surface of the second guide roller, positioning rollers are installed at both ends of the second guide roller, and an inner groove is formed on the positioning roller, the bottom of the inner groove is in contact with the waste strip.

[0019] In a preferred embodiment of the present invention, the limiting roller has a groove for guiding the waste strip, and the waste strip is attached to the upper surface of the limiting roller. A limiting block is rotatably installed on the side wall of the limiting roller, and a limiting rod is movably provided through the limiting block, with the bottom of the limiting rod installed on the worktable.

[0020] In a preferred embodiment of the present invention, a limiting plate is installed on the top of the limiting rod, the limiting plate is positioned to determine the maximum movement path, a limiting spring is sleeved on the limiting rod, one end of the limiting spring is engaged with the worktable, the other end is engaged with the bottom of the limiting block, and during the downward sliding of the waste strip, the limiting roller is pushed to move downward synchronously.

[0021] Compared with the prior art, the present invention has the following advantages:

[0022] This invention achieves efficient processing of steel strips of varying thicknesses by switching the functions of the first and second guide rollers before and after rotation. When processing steel strips of normal thickness, the two guide rollers work together to smoothly guide the waste and steel strip. The waste is conveyed outward by the limiting roller, while the steel strip smoothly enters the subsequent process, ensuring efficient and stable routine production. When cutting thicker steel strips, the flip motor starts, causing the two guide rollers to rotate. The first guide roller lifts the steel strip and moves it to the inclined friction plate on the side wall of the cutting blade, thoroughly grinding burrs. The pressure roller synchronously limits the movement to ensure uniform grinding. The second guide roller presses down on the waste, creating a counterforce with the first guide roller to generate shearing force. This, combined with the cutting blade, reduces cutting resistance and improves cutting efficiency. The ground steel strip and waste, guided by the second guide roller, enter the water tank of the workbench for cleaning, effectively removing debris, impurities, and metal particles, ensuring the steel strip is clean and preventing waste residue from affecting subsequent processing.

[0023] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention.

[0040] Example 1:

[0041] like Figures 1 to 10 As shown, a steel strip trimming device for cold rolling stainless steel strip includes a worktable 1 and a matching base plate 12.

[0042] A conveying roller 15 for conveying steel strip is mounted on the base plate 12, and a pair of top plates 151 for guiding the position of the steel strip are provided on the conveying roller 15.

[0043] A circular roller 13 for supporting the steel strip is rotatably mounted on the substrate 12;

[0044] A cutting blade 14 is mounted on a base plate 12 that is vertically opposite to the roller 13. A friction plate 141 is mounted on the inner side wall of the cutting blade 14, and the surface of the friction plate 141 is inclined.

[0045] The substrate 12 is equipped with a first guide roller 22 and a second guide roller 23 that rotate synchronously. The first guide roller 22 is used to guide the cut steel strip to slide onto the friction plate 141 for grinding, and the second guide roller 23 is used to guide the ground steel strip and waste material to move to the water tank 16 installed on the surface of the worktable 1 for cleaning. The second guide roller 23 is also used to guide the cut waste material to move downward and cooperate with the upward moving steel strip to generate shearing force at the cutting position.

[0046] The workbench 1 is also equipped with a limit roller 3 for adjusting the tension of the waste strip after cutting.

[0047] The above structure realizes an integrated process of steel strip conveying, cutting, grinding and cleaning, which greatly improves production efficiency. The conveying roller 15 and the top plate 151 ensure stable conveying of the steel strip, reducing cutting deviation and material waste caused by unstable conveying; the cooperation between the circular roller 13 and the cutting blade 14 makes the cutting process more precise and efficient; the guiding effect of the first guide roller 22 and the second guide roller 23 ensures the orderly handling of the steel strip and waste after cutting, avoiding the problems of waste accumulation and chaotic steel strip handling; the limit roller 3 adjusts the tension of the waste strip, further ensuring smooth waste conveying and reducing downtime for maintenance.

[0048] like Figures 1 to 10As shown in the specific embodiment, four support legs 11 are installed at the bottom of the workbench 1, and reinforcing ribs 111 are installed on adjacent support legs 11. The heights of adjacent reinforcing ribs 111 are different to reduce excessive local stress. A base 121 is installed at the bottom of the base plate 12. The base 121 is boss-shaped and is bolted to the workbench 1. The above structure enhances the overall stability of the device, reduces the risk of equipment damage caused by stress concentration, extends the service life of the equipment, and reduces maintenance costs. The bolted connection between the boss-shaped base 121 and the workbench 1 facilitates the installation, disassembly, and maintenance of the equipment, improving equipment maintenance efficiency.

[0049] like Figures 1 to 10 As shown, furthermore, positioning plates 131 are installed at both ends of the circular roller 13, and the diameter of the positioning plates 131 is larger than the diameter of the circular roller 13. A drive shaft 133 is installed at the rotation center of the positioning plates 131, and the drive shaft 133 movably passes through the base 121. A drive motor 134 is installed at the end of the drive shaft 133, and the housing of the drive motor 134 is installed on the base plate 12. A cutting slit 132 is opened on the circular roller 13, and the cutting slit 132 is vertically aligned with the cutting blade 14. The positioning plates 131 can effectively prevent the steel strip from shifting laterally during the cutting process, ensuring cutting accuracy. The drive motor 134 drives the circular roller 13 to rotate through the drive shaft 133, providing stable power for the cutting process and ensuring the continuity and stability of the cutting process. The vertical alignment design of the cutting slit 132 with the cutting blade 14 makes the cutting more precise, reduces cutting errors, and improves product quality.

[0050] Example 2:

[0051] The difference between the above embodiments and this embodiment is that: Figures 1 to 10 As shown, a number of pairs of ball bearings 152 are installed on the top plate 151, and a positioning rod 154 is installed on the other end of the top plate 151. A positioning cover 153 is inserted into the positioning rod 154. The positioning cover 153 is installed on the side wall of the base plate 12. A baffle 155 is slidably arranged inside the positioning cover 153. One end of the baffle 155 is connected to the positioning rod 154. A compression spring 156 is engaged between the other end of the baffle 155 and the inner wall of the positioning cover 153. The compression direction of the compression spring 156 and the movement direction of the positioning rod 154 are both on the same straight line. The ball bearing 152 significantly reduces the friction between the top plate 151 and the steel strip, reducing scratches and other damage to the steel strip surface caused by friction and improving the product surface quality. The adaptive limiting structure composed of the positioning rod 154, positioning cover 153, baffle 155 and compression spring 156 can automatically adjust the limiting force on the steel strip according to the different widths and conveying conditions of the steel strip, ensuring stable conveying of the steel strip while avoiding damage to the steel strip due to excessive tightness, thus improving the equipment's adaptability to steel strips of different specifications.

[0052] like Figures 1 to 10As shown, in a specific embodiment, a cutting motor 142 is mounted on the rotation center of the cutting blade 14. A connecting frame 143 is mounted on the housing of the cutting motor 142. The output shaft of the cutting motor 142 is rotatably connected to the connecting frame 143. A positioning seat 222 is mounted on the side wall of the connecting frame 143. A pressure roller 221 is mounted on the positioning seat 222. The pressure roller 221 is adapted to the first guide roller 22 and is located above the first guide roller 22. The pressure roller 221 and the first guide roller 22 are used to position the steel strip to facilitate grinding. The cutting motor 142 provides strong power to the cutting blade 14, ensuring that the cutting blade 14 rotates at high speed and improving cutting efficiency. The pressure roller 221 cooperates with the first guide roller 22 to accurately position the steel strip during grinding, ensuring that the steel strip is always in the optimal grinding position, improving the grinding effect and grinding quality, and making the surface of the ground steel strip smoother and flatter.

[0053] like Figures 1 to 10 As shown, furthermore, an electric push rod 144 is installed on the connecting frame 143. The electric push rod 144 is used to position the cutting blade 14, and a mounting bracket 145 is installed at the output end of the electric push rod 144. The mounting bracket 145 is L-shaped, and its sidewall is connected to the base plate 12. A slant plate 146 is installed at the bend of the mounting bracket 145. The electric push rod 144 can precisely adjust the position of the cutting blade 14 according to the cutting requirements of steel strips of different specifications, realizing flexible cutting of steel strips of different thicknesses and widths, and improving the versatility of the equipment. The design of the L-shaped mounting bracket 145 and the slant plate 146 enhances the stability of the installation structure of the cutting blade 14, reduces cutting deviations caused by vibration and other factors during the cutting process, and further improves the cutting accuracy.

[0054] Example 3:

[0055] The difference between the above embodiments and this embodiment is that: Figures 1 to 10 As shown, a positioning frame 211 is installed at the center of the first guide roller 22 and the second guide roller 23. A synchronous shaft 2 is installed through the positioning frame 211, and the synchronous shaft 2 movably passes through the base plate 12. A flip motor 21 is installed at the end of the synchronous shaft 2, and the housing of the flip motor 21 is installed on the side wall of the base plate 12. This structure drives the synchronous shaft 2 to rotate through the flip motor 21, thereby achieving synchronous rotation of the first guide roller 22 and the second guide roller 23, thus changing the conveying path of the steel strip and waste material. It can flexibly handle different cutting situations (such as thick steel strip cutting), improving the adaptability of the equipment and its ability to cope with complex working conditions.

[0056] like Figures 1 to 10As shown, in a specific embodiment, a first sleeve 24 is sleeved at one end of the synchronous shaft 2, with the bottom of the first sleeve 24 fitting against the waste strip. A second sleeve 241 is sleeved at the center of the synchronous shaft 2, with the bottom of the second sleeve 241 fitting against the cut steel strip. The cut steel strip also fits against the lower surface of the second guide roller 23. Positioning rollers 231 are installed at both ends of the second guide roller 23, and the positioning rollers 231 have inner grooves 232, with the bottom of the inner grooves 232 fitting against the waste strip. The first sleeve 24 and the second sleeve 241 respectively limit the movement of the waste strip and the cut steel strip, ensuring that the waste and steel strip can still be stably conveyed when the guide roller changes its conveying path, avoiding problems such as deviation and curling, and ensuring the smooth progress of the entire trimming process. The design of the positioning rollers 231 and the inner grooves 232 further enhances the positioning effect of the waste strip and improves the stability of waste conveying.

[0057] like Figures 1 to 10 As shown, the limiting roller 3 has a groove for guiding the waste belt, and the waste belt adheres to the upper surface of the limiting roller 3. A limiting block 31 is rotatably mounted on the side wall of the limiting roller 3. A limiting rod 311 is movably inserted through the limiting block 31, and the bottom of the limiting rod 311 is mounted on the worktable 1. A limiting plate 312 is mounted on the top of the limiting rod 311, and the limiting plate 312 positions the maximum movement path. A limiting spring 313 is sleeved on the limiting rod 311. One end of the limiting spring 313 is engaged with the worktable 1, and the other end is engaged with the bottom of the limiting block 31. As the waste belt slides downward under pressure, it pushes the limiting roller 3 to move downward synchronously. The limiting roller 3 and the limiting spring 313 can automatically adjust the tension of the waste belt according to the pressure change of the waste, effectively avoiding equipment failure caused by waste accumulation or poor conveying, ensuring the continuity of waste conveying, reducing manual intervention, and improving the degree of automation and production efficiency.

[0058] The implementation principle of the stainless steel strip edge trimming device for cold rolling of the present invention is as follows:

[0059] When performing cold rolling and trimming of stainless steel strip, the steel strip to be processed is placed on the conveyor roller 15. The top plate 151 on the conveyor roller 15 reduces the friction between the steel strip and the roller through the ball bearings 152. At the same time, the structure consisting of the positioning rod 154, the positioning cover 153, the baffle 155 and the compression spring 156 can limit and self-adjust the steel strip to ensure that the steel strip maintains a stable position during the conveying process.

[0060] The steel strip moves forward under the drive of the conveyor roller 15, passing over the circular roller 13. The circular roller 13 is driven to rotate by the drive motor 134 through the transmission shaft 133, and the cutting slit 132 on its surface is vertically aligned with the cutting blade 14. The cutting motor 142 drives the cutting blade 14 to rotate at high speed, and the electric push rod 144 adjusts the position of the cutting blade 14 through the mounting bracket 145, so that the cutting blade 14 can accurately cut the steel strip.

[0061] Under normal circumstances, the waste material after cutting is conveyed outward through the first guide roller and the second guide roller, and the waste material overlaps on the limit roller and is conveyed outward synchronously.

[0062] However, when cutting thicker steel strips, burrs easily appear on the cut surface, and a large amount of debris is generated at the cutting location, while the cutting speed also slows down. At this time, the flip motor 21 is started, driving the synchronous shaft 2 to rotate, which in turn causes the first guide roller 22 and the second guide roller 23 to rotate.

[0063] After the first guide roller 22 rotates, its position changes, and it lifts the steel strip upward through contact with the steel strip. Since the first guide roller 22 corresponds to the friction plate 141 on the side wall of the cutting disc 14, the lifted steel strip can accurately move onto the friction plate 141. The surface of the friction plate 141 is inclined. This inclined design allows the contact area and angle between the steel strip and the friction plate 141 to change as the strip moves, thus adapting to the grinding requirements of different thicknesses. For thicker steel strips producing longer burrs, the steel strip can achieve a longer grinding stroke and greater grinding pressure as it moves along the inclined friction plate 141, ensuring that the burrs are fully removed.

[0064] Meanwhile, the pressure roller 221, mounted on the positioning seat 222, is located above the first guide roller 22. After the steel strip is lifted and moved upward, the pressure roller 221 maintains close contact with the steel strip, limiting the steel strip in its higher position. The pressure roller 221, through its own pressure, restricts the swaying and deviation of the steel strip during the grinding process, ensuring that the steel strip always moves stably along the inclined surface of the friction plate 141, making the grinding process more uniform and efficient, and guaranteeing grinding quality.

[0065] After the second guide roller 23 rotates, its movement trend is to press the waste generated by cutting downwards.

[0066] During this process, the first guide roller 22 moves the steel strip upward, while the second guide roller 23 presses the waste material downward, creating opposing forces that generate shearing force. This shearing force, in conjunction with the cutting force of the cutting blade 14 itself, plays a crucial auxiliary role in cutting thick steel strips. When cutting thick steel strips, the material has greater hardness and thickness. Relying solely on the cutting force of the cutting blade 14 not only results in slow cutting speed but also easily leads to uneven cut surfaces and burrs. The shearing force, however, applies an additional pulling force to the steel strip during the cutting process, helping the cutting blade 14 to cut into the steel strip more smoothly, reducing cutting resistance, and thus improving cutting efficiency and quality.

[0067] Meanwhile, the first sleeve 24 and the second sleeve 241 play an indispensable limiting role throughout the process. The bottom of the first sleeve 24 is in contact with the scrap strip. As the second guide roller 23 rotates and presses down on the scrap, the first sleeve 24 can stably limit the position of the scrap strip, preventing the scrap from shifting or curling during transportation and ensuring that the scrap is transported downward along the predetermined path. The bottom of the second sleeve 241 is in contact with the cut steel strip. As the first guide roller 22 moves the steel strip upward, the second sleeve 241 closely contacts the steel strip, providing support and guidance, ensuring that the steel strip remains stable as it is guided to the friction plate 141, and preventing swaying or separation from the transportation path. Working together, even when the guide roller changes the transportation path of the scrap and steel strip, the two sleeves can still ensure the stable forward movement of the scrap and steel strip, enabling the entire edge-cutting device to operate efficiently and stably when processing thick steel strips, completing a series of tasks such as edge cutting, grinding, and scrap processing.

[0068] During the above process, the waste material is adhered to the limiting roller 3. The structure consisting of the groove, limiting block 31, limiting rod 311, and limiting spring 313 on the limiting roller 3 adaptively adjusts the tension of the waste strip according to the pressure changes of the waste material, preventing the overall operation from being affected by waste accumulation or poor conveying. After grinding, the steel strip, guided by the second guide roller 23, moves together with the waste material to the water tank 16 on the surface of the worktable 1 for cleaning. This cleans away residual debris and impurities generated during grinding, ultimately completing a series of operations such as efficient edge trimming, grinding, cleaning, and waste treatment of the thick steel strip.
