Description

Technical Field

[0001] This invention relates to the field of cold rolling technology, specifically to a cold rolling equipment for high-nickel stainless steel chip carriers with anti-displacement function. Background Technology

[0002] High-nickel stainless steel is often used in the manufacture of chip scaffolds due to its good corrosion resistance, thermal stability and high strength. Before being manufactured into chip scaffolds, high-nickel stainless steel coils need to be cold rolled to ensure that the high-nickel stainless steel meets the size and performance requirements of chip scaffold manufacturing.

[0003] Existing cold rolling equipment often results in varying degrees of burrs or unevenness on the edges of cold-rolled steel strips. This necessitates transferring the strip to grinding equipment, increasing processing time. Furthermore, because the equipment cannot automatically adjust the amount of lubricant used based on the vibration caused by the friction between the work rolls and the steel strip during cold rolling, insufficient lubricant can lead to excessive friction between the work rolls and the steel strip, resulting in excessive vibration of the rolls and defects such as ripples in the cold-rolled steel strip. Conversely, excessive lubricant can reduce the friction between the work rolls and the steel strip, causing slippage or jamming and affecting the processing speed of cold rolling. Summary of the Invention

[0004] The purpose of this invention is to provide a cold rolling equipment for high-nickel stainless steel chip carriers with anti-displacement function, so as to solve the problems mentioned in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

The cold rolling equipment includes a base, a cold rolling mechanism, a conveying mechanism, an anti-deviation mechanism, and a grinding mechanism. The base and the cold rolling mechanism are fixedly connected, the conveying mechanism and the base are fixedly connected, there are two anti-deviation mechanisms, and the two anti-deviation mechanisms are fixedly connected to the cold rolling mechanism. There are four grinding mechanisms, which are symmetrically distributed vertically, and the four grinding mechanisms and one anti-deviation mechanism are fixedly connected.

[0007] The cold rolling mechanism and conveying mechanism are fixedly installed on the base to ensure stable operation. The high-nickel stainless steel coil for chip bracket processing is transported by the unwinding shaft of the conveying mechanism. The high-nickel stainless steel coil is cold rolled by the cold rolling mechanism. At the same time, the cold rolling mechanism sprays lubricating fluid according to the friction between the rolls and the steel strip to avoid excessive friction between the rolls and the steel strip, which would cause excessive roll vibration and ripples in the cold-rolled steel strip. It also avoids excessive lubricating fluid causing the rolls to slip and affecting the cold rolling speed. Anti-deviation mechanisms are set on both sides of the cold rolling mechanism to correct the steel strip and prevent it from deviating. Four grinding mechanisms are set on the anti-deviation mechanism on the cold rolling exit side. The four grinding mechanisms are located on both sides of the steel strip and are symmetrically distributed to grind the burrs on the upper and lower surfaces of the steel strip, thereby preventing the burrs on the edges of the steel strip caused by cold rolling from affecting the quality of subsequent chip bracket processing. The steel strip is collected by the winding shaft of the conveying mechanism.

[0008] Furthermore, the cold rolling mechanism includes a frame, an adjusting unit, an upper work roll, a lower work roll, a first bearing housing, a drive unit, a support unit, and a lubrication unit.

The vertical position of the No. 1 bearing seat is adjusted by the adjustment units, thereby adjusting the gap between the upper and lower work rolls and thus the thickness of the cold roll. The upper and lower work rolls are driven to rotate by the drive unit, thereby cold rolling the steel strip. At the same time, the lubrication unit automatically adjusts the speed of lubricant spraying according to the friction between the upper and lower work rolls and the steel strip to improve the quality of cold rolling. By setting the diameter of the upper work roll to be larger than that of the lower work roll, excessive local stress is avoided to prevent indentations or scratches, thus improving the quality of cold rolling.

One electrode is fixedly connected to the connecting block, and two electrodes are fixed to the piezoelectric ceramic. Through the connecting block, kinetic energy is transferred to the piezoelectric ceramic, causing it to generate current.

The driven gear drives the other rotating shaft to rotate. By setting two universal joints, the two universal joints are connected by a connecting shaft. The two universal joints are fixed to the rotating shaft and the work roller respectively, so that the rotating shaft drives the work roller to rotate, and is not affected by the vertical position of the work roller.

[0020] Furthermore, the support unit includes a slide rod and a return spring. The frame is provided with a first sliding groove, and the return spring is placed in the first sliding groove.

[0021] The frame is equipped with a first sliding groove, and a return spring is installed in the first sliding groove. The two ends of the return spring are fixed to the first sliding groove and the slide rod, respectively. The slide rod is fixed to the first bearing seat. When the second bearing seat in the vertical direction moves away from each other, the return spring releases its elastic force, causing the first bearing seat to move, thereby widening the gap between the two working rollers.

The base 1 and the cold rolling mechanism 2 are fixedly connected, the conveying mechanism 3 and the base 1 are fixedly connected, two anti-displacement mechanisms 4 are provided, and the two anti-displacement mechanisms 4 are fixedly connected to the cold rolling mechanism 2. Four grinding mechanisms 5 are provided, and the four grinding mechanisms 5 are symmetrically distributed vertically. The four grinding mechanisms 5 and one anti-displacement mechanism 4 are fixedly connected.

[0045] The cold rolling mechanism 2 and the conveying mechanism 3 are fixedly installed on the base 1 to ensure stable operation. The high-nickel stainless steel coil for chip bracket processing is conveyed by the unwinding shaft of the conveying mechanism 3. The high-nickel stainless steel coil is cold rolled by the cold rolling mechanism 2. At the same time, the cold rolling mechanism 2 sprays lubricating fluid according to the friction between the roll and the steel strip to avoid excessive friction between the roll and the steel strip, which would cause excessive roll vibration and ripples in the cold-rolled steel strip. At the same time, it avoids excessive lubricating fluid, which would cause the roll to slip and affect the cold rolling speed. Anti-deviation mechanisms 4 are set on both sides of the cold rolling mechanism 2 to correct the steel strip and prevent it from deviating. Four grinding mechanisms 5 are set on the anti-deviation mechanism 4 on the cold rolling exit side. The four grinding mechanisms 5 are located on both sides of the steel strip and are symmetrically distributed to grind the burrs on the upper and lower surfaces of the steel strip. This prevents the burrs on the edges of the steel strip caused by cold rolling from affecting the quality of subsequent chip bracket processing.

The upper work roll 23 and the lower work roll 24 are driven to rotate by the drive unit 26, thereby cold rolling the steel strip. At the same time, the lubrication unit 28 automatically adjusts the speed of the lubricant spray according to the friction between the upper work roll 23 and the lower work roll 24 and the steel strip to improve the quality of cold rolling. By setting the diameter of the upper work roll 23 to be larger than that of the lower work roll 24, excessive local stress is avoided to prevent indentation or scratches, thus improving the quality of cold rolling.

When the second bearing seat 222 in the vertical direction moves away from each other, the return spring 272 releases its elastic force, causing the first bearing seat 25 to move, thereby increasing the gap between the two working rollers.

[0060] like Figure 12 As shown, the anti-deviation mechanism 4 includes a second motor 41, a bidirectional lead screw 42, a baffle 43, a guide rod 44, and a nut 45. The second motor 41 is fixedly connected to the frame 21. The output end of the second motor 41 is fixedly connected to the bidirectional lead screw 42. The bidirectional lead screw 42 is rotatably connected to the frame 21. There are two baffles 43 and two nuts 45. The two baffles 43 are fixedly connected to the two nuts 45 respectively. The two nuts 45 are drivenly connected to the bidirectional lead screw 42. The guide rod 44 is slidably connected to the two baffles 43. The guide rod 44 is fixedly connected to the frame 21.

[0061] The position of the steel strip is restricted by the baffles 43 on both sides to prevent the steel strip from shifting. The output end of the No. 2 motor 41, which is fixed to the frame 21, is fixed to the bidirectional lead screw 42. The two ends of the bidirectional lead screw 42 are rotatably connected to the frame 21, providing support at both ends. The No. 2 motor 41 drives the bidirectional lead screw 42 to rotate. The nut 45 cooperates with the bidirectional lead screw 42. There are two baffles 43, which are fixed to the two nuts 45 located at both ends of the bidirectional lead screw 42. The guide rod 44 ensures that the baffles 43 can only move linearly, so that the nuts 45 drive the baffles 43 to move along the lead screw. The distance between the two baffles 43 can be adjusted to accommodate the cold rolling of steel strips of various sizes.

[0062] like Figure 13 As shown, the grinding mechanism 5 includes a mounting plate 51, a grinding wheel 52, and a pre-tension spring 53. The baffle 43 is provided with a second sliding groove 431. The mounting plate 51 and the second sliding groove 431 are slidably connected. The pre-tension spring 53 and the second sliding groove 431 are fixedly connected. The pre-tension spring 53 and the mounting plate 51 are fixedly connected.

[0063] By setting four grinding wheels 52, which are respectively set on both sides of the steel strip and distributed vertically, the edge of the steel strip is ground. A second sliding groove 431 is provided by the baffle 43, and the mounting plate 51 is slidably connected to the second sliding groove 431. The pre-tension springs 53 are fixed to the mounting plate 51 on both sides and the second sliding groove 431 respectively. The grinding wheels 52 are installed on the mounting plate 51, so that the grinding wheels 52 on the upper and lower sides can automatically adjust the spacing according to the thickness of the steel strip, thereby adapting to the cold rolling processing of steel strips of various sizes.

[0064] Working principle: The high-nickel stainless steel coil for chip bracket processing is conveyed to the cold rolling mechanism 2 via the unwinding shaft of the conveying mechanism 3. The second motor 41 drives the bidirectional lead screw 42 to rotate, causing the baffles 43 on both sides to move, thereby adjusting the distance between the two baffles 43 and limiting the position of the steel strip to prevent it from shifting. The drive cylinder 221 causes the third bearing seat 224 to move the first bearing seat 25, thereby adjusting the gap between the two work rollers. The first motor 261 drives a rotating shaft 2661 to rotate, causing the drive gear 264 to rotate. This, in turn, causes the drive gear 264 to drive the driven gear 265, resulting in one rotating shaft 2661 driving the other rotating shaft 2661. Universal joints 2662 at both ends of the connecting shaft 2663 are fixed to the rotating shaft 2661 and the work roll respectively, thereby driving the work roll to rotate and cold roll the steel strip. The water pump 283 pumps the lubricant from the storage tank 282 to the delivery pipe 284, and the lubricant is sprayed from several nozzles 285 to lubricate the work roll. When the work roll vibrates, the work roll collides with the connecting block 2813. The kinetic energy is transferred to the piezoelectric ceramic 2812 through the connecting block 2813, causing it to generate current. The electrode 2811 transmits the current to the control module 286. The control module 286 adjusts the output power of the water pump 283 according to the frequency and amplitude of the vibration, thereby controlling the amount of lubricant sprayed.
