Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of stainless steel strip processing, particularly to a steel strip edge cutting device for stainless steel strip cold rolling. BACKGROUND

[0002] Cold rolling is an important metal processing technology that involves applying pressure to metal materials at room temperature to cause plastic deformation, achieving the desired thickness, shape, and performance. In the production of stainless steel strips, cold rolling technology is particularly important because it not only significantly improves the strength, hardness, and surface finish of stainless steel strips, but also optimizes the microstructure and mechanical properties of the material by precisely controlling the deformation process.

[0003] After completing the cold rolling process, the stainless steel strip needs to go through a winding process for storage, transportation, and subsequent deep processing. The winding process requires the stainless steel strip to be flat, tight, and damage-free, which is crucial for ensuring the quality of the final product and the efficiency of subsequent processing. Modern winding equipment is usually equipped with precise tension control systems and automatic centering devices to ensure that the steel strip is uniformly and stably wound on the core shaft during the winding process, avoiding problems such as slack, disorder, or scratches. Efficient winding technology not only improves production efficiency but also reduces material waste caused by improper operation.

[0004] Despite the continuous progress of cold rolling technology and winding equipment, existing winding systems still face challenges in dealing with certain specific situations. In particular, due to the possible slight differences in the thickness of the raw stainless steel strip, even after precise cold rolling processing, the edge area may still have unevenness. These uneven edges may cause uneven winding tension during the winding process, affecting the winding tightness and surface quality of the steel strip, and in severe cases, may even cause damage to the winding equipment or breakage of the steel strip. In addition, edge unevenness also brings difficulties to subsequent cutting, welding, and other processing steps, affecting the yield and quality stability of the final product. SUMMARY

A motor 23 is mounted on a mounting plate 11. Two first spline drive shafts 21 and a second spline drive shaft 26 are rotatably connected between the two mounting plates 11, located on the front and rear sides of the suspension frame 12 respectively. The first spline drive shaft 21 is positioned above the second spline drive shaft 26. All spline drive shafts have grooves, enabling them to drive the components on the shaft to rotate, and the components can slide on the shaft. The first spline drive shaft 21 and the second spline drive shaft 26 on the same side... The two spline drive shafts 26 are connected by a linkage 261 at both ends. The output shaft of the motor 23 is fixedly connected to the first spline drive shaft 21 on the front side. A cutting wheel 22 is provided on the first spline drive shaft 21 on the front side. A third guide roller 27 is provided on each of the two second spline drive shafts 26. The cutting wheel 22 is close to the edge of the third guide roller 27 so that the cutting wheel 22 can cut the stainless steel strip under the cooperation of the third guide roller 27. An adjustment component 24 for adjusting the position of the cutting wheel 22 and the third guide roller 27 is provided in the suspension frame 12. An extrusion component 25 for squeezing the stainless steel strip when cutting the stainless steel strip is provided at the bottom of the adjustment component 24.

[0032] As Figures 3-5 The adjusting assembly 24 comprises a bidirectional threaded screw rod 241, a positioning frame 242, and a shaft sleeve 243. The bidirectional threaded screw rod 241 is rotationally connected in the hanging frame 12. The positioning frame 242 is slidingly connected in the hanging frame 12. The positioning frame 242 is threadedly connected to the top of the bidirectional threaded screw rod 241. The shaft sleeve 243 is slidingly connected to the first spline transmission shaft 21 and the second spline transmission shaft 26. The bottom of the positioning frame 242 is rotationally connected to the shaft sleeve 243. The cutter 22 is fixedly connected to the shaft sleeve 243. The both ends of the connecting member 261 are rotationally connected to the shaft sleeve 243. It is emphasized that the outer ring of the shaft sleeve 243 is provided with a circular ring with a groove, which is similar to the structure of the belt pulley. The inner ring is provided with a stripe in cooperation with the spline transmission shaft. The inner and outer rings of the shaft sleeve 243 can rotate relatively, which plays a role of bearing.

[0033] As Figure 4 and Figure 5 The pressing member 25 comprises a sliding rod 251, a pressing roller 252, and a second elastic member 253. The sliding rod 251 is slidingly connected to the bottom of the front side of the positioning frame 242. The pressing roller 252 is rotationally connected to the bottom of the sliding rod 251.

The other end of the second elastic member 253 is fixedly connected to the sliding rod 251.

[0034] The stainless steel strip after cold rolling passes between the first guide roller 13 and the second guide roller 15. When the stainless steel strip presses the second guide roller 15, the second guide roller 15 compresses the first elastic member 141 through the sliding member 14, so as to ensure the pressing force of the first guide roller 13 and the second guide roller 15, and ensure that the stainless steel strip keeps flat when passing. The edge cutting of the stainless steel strip needs to be completed by the pressing of the cutter 22 and the third guide roller 27 first, then the edge polishing by the polishing member 33, and finally the winding. After the stainless steel coil is processed, the motor 23 is turned off.

[0035] Before cutting the stainless steel strip, the distance between the two cutters 22 is adjusted according to the width of the stainless steel strip after cold rolling. First, the bidirectional threaded screw rod 241 is rotated. The bidirectional threaded screw rod 241 pushes the positioning frame 242 which is threadedly connected thereto. The positioning frame 242 slides in the hanging frame 12. The bottom of the positioning frame 242 slides on the first spline transmission shaft 21 through the shaft sleeve 243. Then, the positioning frame 242 is moved. The cutter 22 slides with the shaft sleeve 243. At the same time, the connecting member 261 slides with the shaft sleeve 243, so as to slide on the first spline transmission shaft 21 and the second spline transmission shaft 26. The position of the shaft sleeve 243 is limited by the bidirectional threaded screw rod 241, so as to fix the position of the cutter 22 and the connecting member 261 after moving, and ensure the stability of the cutter 22. In the process of moving the connecting member 261, the third guide roller 27 is pushed to slide on the second spline transmission shaft 26, so that the end of the third guide roller 27 keeps close to the cutter 22, and the cutting precision is ensured.

[0036] Subsequently, the motor 23 and the winding wheel are started, the motor 23 drives the first spline transmission shaft 21 to rotate, and the protruding edge contacts the cutting wheel 22 during the backward winding of the stainless steel belt, that is, is inserted between the cutting wheel 22 and the third guide roller 27, and the edge cutting is completed by extrusion through the cutting wheel 22 and the third guide roller 27, and during cutting, the top of the stainless steel belt contacts the extrusion roller 252, the extrusion roller 252 presses the stainless steel belt through the elastic force of the second elastic member 253, ensures that the edge of the stainless steel belt does not lift up during cutting to affect the cutting precision, and the third guide roller 27 is driven to rotate during extrusion of the stainless steel belt and the third guide roller 27, so that the second spline transmission shaft 26 rotates between the mounting plates 11, and the cut stainless steel belt moves backward;

[0037] As shown in Figure 6 and Figure 7 , the polishing mechanism 3 includes a first pulley set 31, a second pulley set 32, and a polishing member 33, the end of the third guide roller 27 at the rear end of the suspension frame 12 is sleeved with the polishing member 33, the polishing member 33 is located on one side away from the two third guide rollers 27, the first spline transmission shaft 21 on the front and rear sides is connected through the first pulley set 31, the first pulley set 31 is sleeved on the shaft sleeve 243 of the first spline transmission shaft 21 on the front and rear sides, and the first spline transmission shaft 21 on the rear side is connected through the second pulley set 32.

[0038] When the stainless steel belt passes through the third guide roller 27 at the rear end, the two ends contact the polishing member 33, the first spline transmission shaft 21 on the rear side starts to rotate through the transmission of the first pulley set 31, and then drives the second spline transmission shaft 26 on the rear side to rotate through the second pulley set 32, so as to drive the third guide roller 27 and the polishing member 33 connected to the second spline transmission shaft 26 on the rear side to rotate, since the cut burr of the stainless steel belt generated during edge cutting by the cutting wheel 22 is towards the bottom, and then the polishing member 33 is arranged below and on both sides of the stainless steel belt, the motor 23 drives the first spline transmission shaft 21 on the rear side and the shaft sleeve 243 to rotate through the first spline transmission shaft 21 and the first pulley set 31, and the first pulley set 31 can slide on the first spline transmission shaft 21 through the shaft sleeve 243, and drives the third guide roller 27 to move through the connecting member 261, so that the third guide roller 27 on the second spline transmission shaft 26 driven by the second pulley set 32 can be attached to the stainless steel belt, and the polishing effect of the polishing member 33 is ensured;

[0039] As shown in Figure 8 and Figure 9As shown, the cutting mechanism 4 includes a guide elbow 41, a first gear shaft 42, a second gear shaft 43, a third belt pulley set 44 and a cutting wheel 45, the front side connecting member 261 is connected with the guide elbow 41, the bottom of the guide elbow 41 is rotatably connected with the first gear shaft 42 and the second gear shaft 43, the first gear shaft 42 and the second gear shaft 43 are engaged with each other, the front side second spline transmission shaft 26 is driven by the third belt pulley set 44, and the opposite sides of the left and right first gear shafts 42 and the second gear shafts 43 are both connected with the cutting wheel 45. The extension line of the bottom port of the guide elbow 41 is located between the two cutting wheels 45.

[0040] As shown in Figure 1 and Figure 4 It also includes a collection box 46, and the base 1 is slidably connected with the collection box 46 on the left and right sides, and the collection box 46 is located below the lower end port of the guide elbow 41.

[0041] In order to meet the requirements of thickness and width at the same time, the two sides of some stainless steel strips need to be cut after cold rolling, at this time the two sides of the cut stainless steel strip are continuous as a whole, the cut stainless steel strip is guided by the guide elbow 41, moves downward along the arc surface of the guide elbow 41, and passes between the two cutting wheels 45, the second spline transmission shaft 26 drives the first gear shaft 42 through the third belt pulley set 44, thereby driving the second gear shaft 43 engaged with the first gear shaft 42 to rotate in reverse, so that the two cutting wheels 45 rotate in reverse at the same speed, when the cutting knife on the cutting wheel 45 contacts, the stainless steel strip passing in the middle is extruded, the cutting work is completed, so that there is no too long stainless steel strip which is difficult to handle later, and the collection box 46 can timely collect the cut stainless steel strip and the generated debris, which is convenient for later processing.

[0042] As shown in Figure 10 and Figure 11 It also includes a top cover 5, a lower roller 51, an upper roller 52, an adjusting screw 53 and a fourth belt pulley set 54, the top cover 5 is connected to the top front and rear ends of the two mounting plates 11, the two mounting plates 11 are rotatably connected with two lower rollers 51, and the two mounting plates 11 are slidably connected with two upper rollers 52, the lower roller 51 and the upper roller 52 are located at the front end and the rear end of the mounting plate 11 respectively, the adjusting screw 53 is rotatably connected in the mounting plate 11, the top of the adjusting screw 53 penetrates through the top cover 5, the upper roller 52 is threadedly connected with the adjusting screw 53, the upper roller 52 is provided with a sliding block and a roller structure, the roller is rotatably arranged between the two sliding blocks, the sliding block is slidably connected with the mounting plate 11 and is threadedly connected with the adjusting screw 53, and the adjusting screws 53 connected with the same top cover 5 are driven by the fourth belt pulley set 54.

[0043] The stainless steel strip is extruded by the lower roller 51 and the upper roller 52 before and after cutting and polishing, so that the stainless steel strip can be completely flat during processing. For stainless steel strips of different thicknesses, the worker rotates the adjusting screw 53 and synchronously rotates the adjusting screw 53 connected to the two ends of the upper roller 52 through the fourth pulley set 54, so that the upper roller 52 moves synchronously at both ends, and the upper roller 52 slides in the mounting plate 11 to change the distance between the upper roller 52 and the lower roller 51, ensuring the extrusion effect on the stainless steel strip.

[0044] The stainless steel strip after cold rolling is first extruded by the lower roller 51 and the upper roller 52 to keep it flat, and the height of the upper roller 52 can be adjusted by the cooperation of the adjusting screw 53 and the fourth pulley set 54 to adapt to stainless steel strips of different thicknesses. Then, after completing the width adjustment and passing through the cutting wheel 22 fixed by the shaft sleeve 243 and the third guide roller 27, the motor 23 drives the first spline transmission shaft 21 to rotate, and the extrusion piece 25 makes the stainless steel strip adhere to the third guide roller 27, so that the rotating cutting wheel 22 and the third guide roller 27 perform edge cutting work on the stainless steel strip, and the cut part is guided to the cutoff wheel 45 by the guide elbow 41. The first gear shaft 42 and the second gear shaft 43 driven by the third pulley set 44 rotate in opposite directions to make the cutoff wheel 45 rotate in the opposite direction synchronously to cut off the cut part.

The second guide roller 15 can adaptively adjust the extrusion force according to the thickness of the stainless steel strip through the first elastic element 141 on the sliding element 14, to ensure that the stainless steel strip remains flat. Then, the cut edge is polished by the polishing piece 33, and finally, the stainless steel strip is transmitted again by the lower roller 51 and the upper roller 52.
