A system compensation edge grinding mechanism and operating method for high-strength thin strip steel

Abstract

This invention discloses a system-compensated edge grinding mechanism and operating method for high-strength thin strip steel, relating to the field of strip steel trimming technology. By incorporating coarse grinding units and fine grinding units in edge grinding mechanism one and edge grinding mechanism two, the positions of the coarse and fine grinding units can be switched. This allows for a secondary fine grinding of the thin strip edge after initial coarse grinding using the fine grinding unit, significantly improving the surface finish of the thin strip edge and enhancing product processing efficiency. The grinding rollers are connected to drive shaft one and drive shaft two via flanges, allowing for the replacement of grinding rollers with different outer diameters to accommodate thin strips of varying widths. This ensures that the distance between the two opposing grinding rollers matches the width of the thin strip, meeting grinding requirements and adapting to the grinding of thin strip edges of different sizes, thus expanding the scope of application.

Description

Technical Field

[0001] This invention relates to the field of strip steel trimming technology, specifically to a system compensation grinding mechanism and operating method for high-strength thin strip steel. Background Technology

[0002] Steel strip is a type of metal strip, usually made from cold-rolled or hot-rolled steel plates through cutting, stretching or extrusion. It has the characteristics of high strength, toughness and rigidity, and is widely used in construction, automobiles, power, shipbuilding and other fields.

[0003] After the strip steel is cut, there will be broken edges and burrs on both sides of its edge. The strip steel needs to be trimmed to ensure that the straightness of the thin steel strip edge, the accuracy of the angle and the surface finish meet the processing requirements before it can be used for subsequent product processing.

[0004] The edges of the ground thin steel strip should have a bright surface and should not have scratches, wear or other defects. The subsequent packaging and transportation work can only be carried out after the surface roughness measuring instrument is used for evaluation.

[0005] However, traditional edge grinding devices mostly remove broken edges and burrs through a single grinding process. This grinding process mostly adopts a coarse grinding method, which still leaves scratches and marks on the edge of the thin steel strip after grinding, failing to meet the fine grinding requirements. As a result, the thin steel strip needs to be finely ground again before the actual product is processed, which is time-consuming, labor-intensive, and reduces processing efficiency.

[0006] Secondly, the grinding process of thin steel strips generates a lot of fine metal shavings, which are easily scattered everywhere, making them difficult to clean. Furthermore, the metal shavings dispersed in the air can easily enter the human respiratory tract, harming human health.

[0007] Therefore, this invention proposes a system compensation grinding mechanism and operation method for high-strength thin strip steel to solve the above problems. Summary of the Invention

[0008] To address the shortcomings of existing technologies, this invention provides a system-compensated edge grinding mechanism and operating method for high-strength thin strip steel. This solves the problem that most current edge grinding devices remove burrs and chips through a single grinding process, leaving scratches and marks on the thin steel strip edge after grinding, failing to meet fine grinding requirements. This necessitates a second fine grinding process before actual product processing, which is time-consuming, labor-intensive, and reduces processing efficiency. Furthermore, the edge grinding process generates a large amount of fine metal shavings that easily scatter, making them difficult to clean. These shavings, dispersed in the air, can easily enter the human respiratory tract, posing a health hazard.

[0021] This invention also discloses an operation method for a system compensation edge grinding mechanism for high-strength thin strip steel, which includes the following steps:

[0022] Step 1: Based on the current width of the thin steel strip to be edged, adjust the guide width of guide component 1 and guide component 2 respectively to ensure that the width formed between guide component 1 and guide component 2 matches the size of the thin steel strip. At the same time, adjust the edge grinding width of edge grinding mechanism 1 and edge grinding mechanism 2 to ensure that the edge grinding width of both matches the current width of the thin steel strip.

[0023] Step 2: Start the power mechanism to drive both edge grinding mechanism 1 and edge grinding mechanism 2 to work. Then, use the traction device to pull one end of the thin steel strip so that the thin steel strip passes through guide component 1 and then undergoes the initial coarse edge grinding operation of edge grinding mechanism 1 and edge grinding mechanism 2 before being discharged through guide component 2. After the coarse edge grinding is completed, switch edge grinding mechanism 1 and edge grinding mechanism 2 to fine edge grinding working state. The traction device pushes the thin steel strip through guide component 2 and into the space between edge grinding mechanism 1 and edge grinding mechanism 2. After the fine edge grinding process of edge grinding mechanism 1 and edge grinding mechanism 2, it is discharged through guide component 1.

[0024] Step 3: While the thin steel strip is being roughened and finely ground, the power mechanism drives the first and second grinding mechanisms to work, and simultaneously drives the waste chip treatment mechanism to operate. The waste chip treatment mechanism sucks the metal waste generated during the grinding process into its interior and compresses the scattered metal waste.

[0025] Beneficial effects

[0026] This invention provides a system-compensated edge grinding mechanism and operating method for high-strength thin strip steel. Compared with the prior art, it has the following advantages:

[0027] 1. A system-compensated edge grinding mechanism and operating method for high-strength thin strip steel, wherein a coarse grinding unit and a fine grinding unit are set in edge grinding mechanism one and edge grinding mechanism two, and the positions of the coarse grinding unit and the fine grinding unit can be switched. This enables the fine grinding unit to perform a second fine grinding on the edge of the thin strip after the initial coarse grinding, thereby greatly improving the surface finish of the edge cut of the thin strip. It eliminates the need to grind the steel strip again before product processing, saving processing time and improving product processing efficiency.

[0028] 2. A system compensation grinding mechanism and operating method for high-strength thin strip steel, wherein the grinding rollers and drive shaft one and drive shaft two are connected by flanges, and grinding rollers with different outer diameters can be replaced according to the different widths of thin steel strips, so that the distance between the two relative grinding rollers is adapted to the width of the thin steel strip, thereby meeting the grinding requirements and being suitable for the cutting grinding of thin steel strips of different sizes, thus expanding the scope of application.

[0029] 3. A system compensation grinding mechanism and operating method for high-strength thin strip steel, which, by setting up a waste chip treatment mechanism, can automatically collect the metal waste generated during grinding, preventing the metal waste from flying around and thus avoiding air pollution and harm to human health; secondly, the collected metal waste can be compressed, thereby squeezing the loose metal waste into blocks, reducing its volume, and storing more metal waste in a limited space, thus extending the cleaning time of the metal waste; furthermore, the compressed metal waste has a fixed shape, which is convenient for subsequent transportation and storage.

[0030] 4. A system compensation grinding mechanism and operating method for high-strength thin strip steel. By setting a power mechanism, the grinding mechanism can simultaneously drive the waste chip treatment mechanism to collect and compress the waste chips generated during grinding while driving the first and second grinding mechanisms to perform edge grinding on the thin steel strip. There is no need to set up a separate power device for the operation of the waste chip treatment mechanism, saving the cost of setting up a power device, and making the structure simpler and easier for subsequent inspection and maintenance.

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] like Figures 1 to 13 This invention provides four technical solutions: a system compensation edge grinding mechanism for high-strength thin strip steel, specifically including the following embodiments:

[0047] Example 1: A system compensation edge grinding mechanism for high-strength thin strip steel includes a bearing mechanism 1. The top left and right sides of the bearing mechanism 1 are respectively provided with guide components 2 and 3 for guiding the edge grinding of the thin strip steel. The top of the bearing mechanism 1, located between guide components 2 and 3, is provided with edge grinding mechanisms 4 and 5 for edge grinding of the thin strip steel.

There are two square through slots 16 in each set, one on the front and one on the rear of the top of the operating table 11. The guide assembly 2 includes a bidirectional lead screw 21 rotatably connected to the bottom of the operating table 11 via a bracket and a handwheel 22 fixedly mounted on one end of the bidirectional lead screw 21. The outer wall of the bidirectional lead screw 21 is fitted with a calibration unit 1 23 and a calibration unit 24 for guiding the movement of the thin steel strip.

[0049] Calibration unit 1 23 and calibration unit 24 have the same structure. Calibration unit 1 23 includes a guide frame 231 that is slidably mounted on the top of the operating table 11 and a screw sleeve 232 that is fixedly mounted on the bottom of the guide frame 231 and slidably mounted in the square through groove 16. The screw sleeve 232 is threaded onto the outer wall of the bidirectional screw 21. Multiple mounting grooves are evenly provided at the bottom of the cavity of the guide frame 231. Vertical guide rollers 233 for supporting the thin steel strip are rotatably mounted inside the mounting grooves. Multiple transverse guide rollers 234 for guiding the movement direction of the thin steel strip are evenly rotatably mounted between the bottom and top opposite side walls of the cavity of the guide frame 231.

[0050] Example 2: The main difference between this example and the first technical solution is that: a system compensation edge grinding mechanism for high-strength thin strip steel, edge grinding mechanism 4 and edge grinding mechanism 5 have the same structure. Edge grinding mechanism 5 includes a lower mounting plate 51 rotatably disposed inside the adjustment through hole 15, a support rod 52 fixedly disposed on the top of the lower mounting plate 51, and a mounting plate 53 fixedly disposed on the outer wall of the support rod 52. A coarse grinding unit and a fine grinding unit for edge grinding of thin steel strip are respectively disposed on the top of the lower mounting plate 51 and on both sides of the support rod 52. The coarse grinding unit includes a drive shaft 54 ​​rotatably passing through the lower mounting plate 51. A flange 55 and a gear 56 are fixedly disposed at the top and bottom of the lower mounting plate 51, respectively. A drive shaft 57 rotatably passes through the interior of the mounting plate 53 and at a position opposite to the drive shaft 54. A gear 58 and a flange 59 are fixedly disposed at the top and bottom of the drive shaft 57, respectively. A grinding roller 510 is detachably disposed on the opposite sidewalls of flange 59 and flange 55. The grinding roller 510 has connecting flanges fixedly installed at its top and bottom ends, which are compatible with the structures of flange 2 59 and flange 1 55. Adjacent connecting flanges are connected by bolts, and the grinding roller 510 can be removed and replaced after the bolts are removed. Limiting blocks 511 are fixedly installed on both the front and rear sides of the upper part of the outer wall of the support rod 52. A knob 512 is slidably mounted on the outer walls of both the support rod 52 and the limiting blocks 511. A positioning block 513 compatible with the structure of the positioning hole 13 is fixedly installed on one side of the bottom of the knob 512. The coarse grinding unit and the fine grinding unit are completely identical in structure, except for the different grinding precision of the grinding roller 510. Sliding grooves compatible with the structure of the limiting blocks 511 are opened on both the front and rear sides of the inner wall of the knob 512, and the limiting blocks 511 are slidably positioned inside the sliding grooves. After the positioning block 513 enters the positioning hole 13, the position of the knob 512 is locked. Since the lower mounting plate 51, mounting plate 53, and support rod 52 are fixedly connected, the position of the grinding roller 510 is simultaneously determined when the position of the knob 512 is fixed. The position of the positioning block 513 corresponds to the position of one of the grinding rollers 510. When the positioning block 513 is located in one of the positioning holes 13, one of the grinding rollers 510 is close to the center of the operating table 11, that is, this grinding roller 510 participates in the grinding of the thin steel strip. When the knob 512 is rotated 180 degrees, this grinding roller 510 is replaced by the grinding roller 510 in another position. A ring is fixedly sleeved on the outer wall of the lower mounting plate 51, and an annular groove adapted to the structure of the ring is opened on the inner wall of the adjusting through hole 15.

The controller sets the upper limit pressure of the top of the pressure sensor 83. When the pressure at the top of the pressure sensor 83 reaches a certain value, the controller sends an alarm command to the pressure alarm. The pressure alarm then alerts the operator to handle the metal scrap inside the compression chamber 81 through an audible and visual alarm. An exhaust port is provided on the top of the compression chamber 81 to ensure unobstructed airflow inside. Multiple through holes are evenly distributed on the top of the extrusion block 84 to allow air to be discharged from the compression chamber 81 in a timely manner when the extrusion block 84 moves downward to generate compression. The inner diameter of these through holes is smaller than the minimum particle size of the grinding scrap. A compression block 84 is slidably arranged inside the compression box 81. A lifting rod 85 is fixedly arranged at the top of the compression block 84. The top of the lifting rod 85 slides through the compression box 81 and is fixedly arranged with a spring baffle.

The cylinder 881 is fixedly equipped with gear 3 885, and the bottom end of the drive shaft 4 884 is fixedly equipped with fan blade 886 below the filter plate 883. A discharge port is opened on the side wall of the cylinder 881 above the filter plate 883. A conduit 887 for conveying metal scrap into the compression box 81 is fixedly installed inside the discharge port. An exhaust port is opened at the bottom of the cylinder 881, and the top opening of the suction pipe 882 is located below the grinding roller 510 to facilitate the collection of generated metal scrap.The filter plate 883 is designed with an incline, with the side closer to the compression box 81 being lower than the other side. The bottom of the discharge port and the top of the filter plate 883 are in close contact, ensuring that metal scraps can enter the conduit 887 relatively smoothly. A feed port is provided on the side wall of the compression box 81, and one end of the conduit 887 is fixedly connected to the feed port. The feed port is located below the extrusion block 84.

Simultaneously, adjust the edge-grinding widths of edge-grinding mechanism 1 (4) and edge-grinding mechanism 2 (5) to ensure that their edge-grinding widths match the current width of the thin steel strip. Specifically, manually rotate handwheel 22. Because the lead screw sleeve 232 in calibration unit 1 (23) and calibration unit 2 (24) is connected to the bidirectional lead screw 21 by threads, and the outer wall of the bidirectional lead screw 21 has threads with opposite directions of rotation on both sides, the bidirectional lead screw 21 can rotate... The calibration units 23 and 24 are driven to move closer and further apart synchronously. The distance the guide frame 231 moves is observed by referring to the scale groove 17 on the top of the operating table 11. Since the initial distance between the side walls of the calibration units 23 and 24 is known, the distance between the calibration units 23 and 24 can be precisely adjusted with reference to the scale groove 17 and the known value until it is adjusted to match the distance between the side walls of the transverse guide rollers 234 in the calibration units 23 and 24 and the width of the thin steel strip that needs to be edged. Similarly, the adjustment process of the guide assembly 23 is the same as that of the guide assembly 2, and will not be described again here. When adjusting the edge grinding width of edge grinding mechanism 4 and edge grinding mechanism 5, since the grinding roller 510 and flange 2 59 and flange 1 55 are detachably connected, by replacing the grinding roller 510 with a different outer diameter, the spacing between the grinding rollers 510 in the relative positions of edge grinding mechanism 4 and edge grinding mechanism 2 5 is made to match the width of the thin steel strip. However, the coarse and fine grinding accuracy and height of the replaced grinding roller 510 are not changed, only its outer diameter is changed. The grinding roller 510 that meets the requirements is reinstalled between flange 1 55 and flange 2 59 and locked with bolts.

[0055] Step 2: Start the power mechanism 6 to simultaneously drive the edge grinding mechanism 4 and edge grinding mechanism 5. Then, use the traction device to pull one end of the thin steel strip, so that the thin steel strip passes through the guide assembly 2 and undergoes the initial coarse edge grinding operation of edge grinding mechanism 4 and edge grinding mechanism 5. After that, it is discharged through the guide assembly 3. After the coarse edge grinding is completed, switch edge grinding mechanism 4 and edge grinding mechanism 2 to the fine edge grinding operation state. The traction device pushes the thin steel strip through the guide assembly 2 to enter between edge grinding mechanism 4 and edge grinding mechanism 2. After the second fine edge grinding process of edge grinding mechanism 4 and edge grinding mechanism 2, it passes through the guide assembly. The specific process is as follows: The thin steel strip is placed on the vertical guide roller 233 in calibration unit 1 23 and calibration unit 2 24, and the side wall of the thin steel strip abuts against the outer wall of the transverse guide roller 234. Then, the servo motor 61 is turned on by the control box 7. The output shaft of the servo motor 61 drives the helical gear disk 62 to rotate. Since the bevel gear 2 633 in transmission component 1 63 and transmission component 2 64 are both meshed with the helical gear disk 62, the rotation of the helical gear disk 62 can simultaneously drive the rotation of transmission component 1 63 and transmission component 2 64. The bevel gear 1 632 drives the bevel gear 3 634 to rotate rapidly. Drive gear 635 meshes with gear 58, and the outer diameter of drive gear 635 is much larger than that of gear 58, enabling gear 58 to rotate at a faster speed. Since gear 58 is fixedly connected to drive shaft 57, the traction device pulls the thin steel strip between edge grinding mechanism 4 and edge grinding mechanism 5, and it contacts the outer walls of the two opposing coarse grinding units. The rapidly rotating grinding roller 510 grinds the sides of the thin steel strip, removing burrs and debris. The servo motor is turned off when the thin steel strip has completely passed between edge grinding mechanism 4 and edge grinding mechanism 5. Machine 61: Manually pull up knob 512 to disengage positioning block 513 from positioning hole 13. Then, rotate knob 512 180 degrees to move fine grinding unit into working position, i.e., close to the thin steel strip. Next, push knob 512 downward to move positioning block 513 back into positioning hole 13 on the other side, locking the position of fine grinding unit. Following the working method of coarse grinding unit, the thin steel strip is pushed in the opposite direction by traction equipment. After passing through edge grinding mechanism 1 4 and edge grinding mechanism 2 5, the thin steel strip undergoes secondary fine grinding, smoothing out scratches and wear on the side of the thin steel strip.

[0056] Step 3: While the thin steel strip is being roughened and finely ground twice, the power mechanism 6 drives the first grinding mechanism 4 and the second grinding mechanism 5 to work simultaneously, which can also drive the waste chip treatment mechanism 8 to operate. The waste chip treatment mechanism 8 sucks the metal waste generated by the grinding into its interior and compresses the scattered metal waste. The specific process is as follows: Since gear 3 885 and gear 1 56 are meshed, even after the fine grinding unit and the coarse grinding unit switch positions, gear 1 56 in both grinding units will simultaneously complete the meshing connection between gear 1 56 and gear 3 885 after locking in position. When gear 1 56 drives gear 3 885 to rotate rapidly, the transmission shaft 4 884 drives the fan blade 886 to rotate, generating suction force. The metal waste generated during grinding is sucked into the cavity of the cylinder 881 through the suction pipe 882. After the metal waste is filtered by the filter plate 883, the air is discharged through the exhaust port at the bottom of the cylinder 881. Under its own gravity, the metal waste slides down the inclined surface of the filter plate 883 into the guide tube 887. Due to the inclined design of the guide tube 887 towards the compression box 81, the metal waste continues to slide down into the compression box 81. Inside the compression chamber 81, the rotation of the transmission shaft 884 drives the worm gear 811 to rotate the worm wheel 812. The power is transmitted through the transmission shaft 89 to drive the cam 810 to rotate. During the rotation of the cam 810, it intermittently pushes the lifting rod 85 downward. The extrusion block 84 extrudes the metal scrap accumulated in the compression chamber 81. As the metal scrap gradually increases, the distance between the bottom of the extrusion block 84 and the metal scrap gradually decreases, that is, the pressure of the extrusion block 84 on the metal scrap gradually increases. The pressure sensor 83 transmits the pressure data to the controller in real time. When the pressure sensed by the pressure sensor 83 reaches the set value, the controller sends an alarm command to the pressure alarm to remind the staff that the metal scrap collected in the compression chamber 81 is about to be full and to clean the metal scrap in the compression chamber 81 in time.
