Description
Technical Field
[0001] This utility model relates to the technical field of steel production and processing, specifically to a high-stability roughing rolling device for producing serrated flat steel. Background Technology
[0002] In industrial production, rough rolling, as a crucial starting process in flat steel production, plays a decisive role in product quality. Currently, most rough rolling equipment for sawtooth I-beam flat steel production employs two-roll mills. However, this type of equipment, due to its relatively fixed and simple structure, is prone to instability when dealing with workpieces of different specifications. For example, when rolling flat steel of different thicknesses, two-roll mills often use a design where one roll is fixed and the other is movable to adjust the rolling thickness. However, the movable roll is easily interfered with by the mounting mechanism during operation, leading to unstable rolling results and potentially damaging the workpiece. Furthermore, traditional two-roll mills achieve drive through meshing gear sets located at the outer ends of the two rolls, concentrating the driving force at the outer ends. This results in poor relative motion stability between the two rolls, easily causing fluctuations in the flat steel rolling quality. Therefore, developing a highly stable rough rolling device for sawtooth I-beam flat steel production is urgently needed to effectively improve the stability of the rough rolling process and product quality.
[0003] Application number CN202123039461.4 discloses a highly stable roughing rolling device for producing serrated flat steel. The device includes a mounting frame, with bearings A located on the lower part of the inner walls on both sides of the mounting frame. Slide grooves are formed on the upper part of the inner walls on both sides of the mounting frame. A rotating shaft A is installed inside the bearings A, and a drive pulley is located on one side of the outer wall of the rotating shaft A. A two-roll pressing mechanism is installed inside the slide grooves. The device has a reasonable structure. By incorporating the two-roll pressing mechanism, a drive motor is coordinated with the two-roll pressing mechanism, and the I-shaped base is fixed to the mounting frame with fastening bolts, increasing the stability of the two-roll pressing mechanism and enabling stable roughing production of serrated flat steel on the roughing rolling device. It also features a simple structure, convenient operation, and eliminates many cumbersome steps, effectively improving work efficiency and production stability. However, it has shortcomings. When rolling, the device is suitable for relatively flat surfaces. When processing irregularly shaped or differently thick surfaces, the device cannot differentiate between them.

[0025] Please see Figures 1-4 As shown, this utility model is a high-stability roughing rolling device for producing serrated flat steel, including a support assembly 1, a roughing rolling assembly 2 installed in the middle of the support assembly 1, a width adjustment assembly 3 fixedly installed on the top of the roughing rolling assembly 2, and a rolling surface adjustment assembly 4 fixedly installed on one side of the roughing rolling assembly 2. The width adjustment assembly 3 is fixedly installed on the top of the support assembly 1.
[0026] The rolling surface adjustment assembly 4 includes a brake motor 401. Two brake motors 401 are fixedly installed on the top and bottom of the mounting bracket 404, and a telescopic rod 402 is installed on one side of the brake motor 401.
[0027] By installing the rolling surface adjustment component 4 on the device, the position of the roughing surface can be adjusted left and right according to different working scenarios and different rolling surface roughing components 2. This makes the use of the device more convenient and flexible.
[0028] The support assembly 1 includes support columns 101, with fixed bases 102 fixedly installed at the bottom of the two support columns 101. The two support columns 101 are connected by a connecting plate 103. The inner wall of the support columns 101 has a lifting groove 104. The support columns 101, fixed bases 102, and connecting plates 103 together form a stable support structure. The mounting holes of the fixed bases 102 allow the device to be securely installed on the production workshop floor, ensuring the stability of the entire device during operation. The lifting groove 104 on the inner wall provides guidance and support for the lifting of the roughing rolling assembly 2.
[0029] The roughing rolling assembly 2 includes a lifting mounting block 201. The two sides of the lifting mounting block 201 are slidably mounted inside the lifting chute 104 via limiting sliders 202. A rotating rod 203 is fixedly mounted in the middle of the lifting mounting block 201, and a fixed mounting block 204 is correspondingly provided on the bottom side of the lifting mounting block 201. A fine roller 205 is fixedly mounted inside the rotating rod 203, and a coarse roller 206 is fixedly mounted in the middle of the fine roller 205. The lifting mounting block 201 moves vertically through the cooperation of the limiting sliders 202 and the lifting chute 104. The fine roller 205 and coarse roller 206 mounted on the rotating rod 203 apply pressure to the flat steel through rotation, achieving roughing processing.
[0030] The width adjustment assembly 3 includes a pneumatic telescopic pump 301, which is fixedly installed on the top of the support column 101 via a fixed bracket 302. A push rod 303 is installed at the bottom of the pneumatic telescopic pump 301, and a lifting mounting block 201 is fixedly installed at the bottom of the push rod 303. The pneumatic telescopic pump 301 uses gas pressure to drive the push rod 303, thereby driving the lifting mounting block 201 to move up and down in the lifting slide 104, thereby adjusting the distance between the coarse roll pressure shaft 206 and the fine roll pressure shaft 205 in the roughing assembly 2, and realizing the adjustment of the rolling width of the flat steel.
[0031] A brake lever assembly 403 is installed at the end of the telescopic rod 402.
[0032] The brake lever assembly 403 includes a first connecting hinge end 4031, which is installed at the end of the telescopic rod 402. A brake push rod 4032 is fixedly installed on the other side of the first connecting hinge end 4031, and a second connecting hinge end 4033 is fixedly installed on the other end of the brake push rod 4032. The second connecting hinge end 4033 is fixedly installed at the other end of the rotating rod 203. The brake motor 401 rotates to drive the telescopic rod 402 to extend and retract. The brake lever assembly 403 at the end of the telescopic rod 402 converts the linear motion of the telescopic rod 402 into an angular change of the rotating rod 203 through the first connecting hinge end 4031, the brake push rod 4032, and the second connecting hinge end 4033, thereby realizing the adjustment of the rolling surface angle of the roughing assembly 2 and meeting the production requirements of different specifications of serrated flat steel.
[0033] This highly stable serrated flat steel production roughing unit is based on the principles of mechanical transmission and automated control. Through the coordinated operation of its components, it achieves the roughing process of the flat steel. The support column 101, fixed base 102, and connecting plate 103 together form a stable support structure. The mounting holes of the fixed base 102 allow the unit to be securely installed on the production workshop floor, ensuring the stability of the entire unit during operation. The lifting groove 104 on the inner wall provides guidance and support for the lifting of the roughing rolling assembly 2. The lifting mounting block 201, through the cooperation of the limiting slider 202 and the lifting groove 104, achieves vertical movement. The fine roller 205 and coarse roller 206 mounted on the rotating rod 203 apply pressure to the flat steel through rotation, achieving rough rolling. The pneumatic telescopic pump 301 uses gas pressure to drive the push rod 303, which in turn drives the lifting mounting block 201 to move up and down in the lifting slide 104, thereby adjusting the distance between the coarse roller 206 and the fine roller 205 in the rough rolling assembly 2, and adjusting the rolling width of the flat steel. The brake motor 401 rotates to drive the telescopic rod 402 to extend and retract. The brake lever assembly 403 at the end, through connecting hinge end one 4031, brake push rod 4032, and connecting hinge end two 4033, converts the linear motion of the telescopic rod 402 into the angular change of the rotating rod 203, thereby realizing the adjustment of the rolling surface angle of the roughing assembly 2 to meet the production requirements of different specifications of serrated flat steel. The support assembly 1 is securely installed on the production workshop floor through the mounting holes on the fixed base 102. The connection of the connecting plate 103 is checked to ensure the stability of the support assembly 1. The pneumatic telescopic pump 301, brake motor 401, and other power components are debugged to ensure normal operation. According to the specifications of the serrated flat steel to be processed, the rolling width of the roughing assembly 2 is set using the width adjustment assembly 3. The pneumatic telescopic pump 301 is started, causing it to move the lifting mounting block 201 within the lifting slide 104 via the push rod 303, adjusting the distance between the coarse roller pressure shaft 206 and the fine roller pressure shaft 205 to a suitable position. Simultaneously, the rolling surface adjustment assembly 4 is used to set the rolling surface angle of the roughing assembly 2. Start the brake motor 401, and adjust the angle of the rotating rod 203 via the telescopic rod 402 and brake rod assembly 403 to bring the rolling surfaces of the coarse roller 206 and fine roller 205 to the required angle. Feed the flat steel to be processed into the roughing assembly 2. The coarse roller 206 and fine roller 205 apply pressure to the flat steel during rotation, performing roughing. If adjustment of the rolling width or rolling surface angle is needed during processing, it can be made at any time via the width adjustment assembly 3 and rolling surface adjustment assembly 4. After completing the roughing of the flat steel, remove the processed flat steel. Reset the width adjustment assembly 3 and rolling surface adjustment assembly 4, turn off the pneumatic telescopic pump 301, brake motor 401, and other power components, and clean and maintain the equipment to prepare for the next processing cycle.
