Description

Technical Field

[0001] This utility model relates to the field of wear-resistant steel plate technology, and specifically to a rolling mill for the production of wear-resistant steel plates. Background Technology

[0002] After the existing steel plate is welded, the heat generated during welding will cause a temperature difference between the weld and the surrounding steel plate, resulting in thermal stress. The uneven expansion and contraction of different metal materials will cause deformation and make the steel plate appear bent. Therefore, in the production of wear-resistant steel plates, it is necessary to roll the steel plate to restore its flatness.

[0003] In existing rolling processes for flatness testing of steel plates after welding, the rolling mill provides relatively simple rolling power, which cannot be adjusted according to the power requirements of steel plates with different strengths. This results in energy waste during the rolling of low-strength wear-resistant steel plates. Therefore, a rolling mill for the production of wear-resistant steel plates is proposed to provide a rolling mechanism with combined power supply for wear-resistant steel plates produced by welding. This can improve the flatness of the steel plates after welding, achieve flexible power supply, and effectively save energy costs. Summary of the Invention

[0004] To address the problems in the existing technology, this utility model provides a rolling mill for the production of wear-resistant steel plates. It provides a rolling mechanism with power combination and distribution for wear-resistant steel plates produced by the surfacing process, which can improve the flatness of the steel plate after surfacing, realize flexible power distribution, and effectively save power energy costs.

[0005] The technical solution adopted by this utility model to solve its technical problem is a rolling mill for the production of wear-resistant steel plates, comprising:

[0006] The frame shall have at least one set for supporting the rolling components;

[0007] The rolling section is mounted on the frame;

[0008] The power supply unit is mounted on the frame and connected to the rolling section;

[0009] Surface treatment department.

[0010] By adopting the above technical solution, a rolling mechanism with power supply is provided for wear-resistant steel plates produced by the surfacing process, consisting of a frame, rolling section, power supply section and surface treatment section. This improves the flatness of the steel plate after surfacing and enables rolling treatment of wear-resistant steel plates with different hardness and strength using different rolling drive forces.

[0011] Specifically, the racks are arranged at equal intervals, and the inlet and outlet ends of adjacent racks correspond to each other. The surface treatment unit is located at the inlet end of the first rack arranged at equal intervals.

[0012] Specifically, the rolling section includes:

[0013] Roller frame, located at the top of the machine frame;

[0014] The lower roll is located at the bottom inside the roll frame;

[0015] The upper roll is located on top of the lower roll.

[0016] By adopting the above technical solution, the wear-resistant steel plate is rolled through the rolling section, resulting in better flatness of the steel plate after welding.

[0017] Specifically, the power supply unit includes:

[0018] The motor is mounted on the frame;

[0019] The speed reducer is mounted on the frame and connected to the motor;

[0020] The first pulley is provided in at least one set and is connected to the motor, the reducer and the lower roller;

[0021] The second pulley is mounted on the upper roller;

[0022] The lower gear is mounted on the lower roller;

[0023] The upper gear is mounted on the upper roller and meshes with the lower gear.

[0024] By adopting the above technical solution, the power required for rolling is distributed through the power distribution unit to match the rolling operation of steel plates of different strengths. When rolling wear-resistant steel plates with slightly lower strength, only some of the drive motors need to be turned on. However, when rolling wear-resistant steel plates with high strength, all motors can be turned on to provide driving force, thereby achieving flexible power distribution and effectively saving power energy costs.

[0025] Specifically, the first pulley is connected to the drive shaft of the motor, the input shaft and output shaft of the reducer, and the shaft end of the lower roller. The first pulley of the motor drive shaft is connected to the first pulley on the input shaft of the reducer via a belt. The first pulley of the output shaft of the reducer is connected to the first pulley on the lower roller via a belt. The second pulleys of the upper roller are connected to each other via belts.

[0026] Specifically, the surface treatment section includes:

[0027] Cabinet;

[0028] A through-hole is created in the cabinet body;

[0029] The vacuum cleaner is mounted on the cabinet and located at the bottom of the through-panel opening;

[0030] The air vent is located on the outside of the cabinet.

[0031] Specifically, the vacuum cleaner has two sets of dust inlets, which are respectively located at the top and bottom of the through-plate opening.

[0032] By adopting the above technical solution, the surface of the wear-resistant steel plate to be rolled is cleaned by the surface treatment department to reduce the debris remaining on the surface of the wear-resistant steel plate after grinding in the welding process, thus ensuring the quality of the wear-resistant steel plate after rolling.

[0033] The beneficial effects of this utility model are as follows: The assembly, consisting of a frame, rolling section, power supply section, and surface treatment section, provides a rolling mechanism with combined power supply for wear-resistant steel plates manufactured using the surfacing welding process. This improves the flatness of the welded steel plate and allows for rolling of wear-resistant steel plates with different hardness and strength using different rolling drive forces. When rolling lower-strength wear-resistant steel plates, only some of the drive motors need to be activated, while for high-strength wear-resistant steel plates, all motors can be activated to provide driving force, thus achieving flexible power supply. This method can effectively save on the power and energy costs of wear-resistant steel plate production. Simultaneously, it can clean the surface of wear-resistant steel plates about to undergo roll forming, reducing residual debris after grinding, thus ensuring the quality of the wear-resistant steel plates after roll forming. It also solves the problem of wasted power during the roll forming process of existing steel plates after welding, where the rolling mill provides only a single type of power and cannot adjust the power supply according to the different strengths of the steel plates, resulting in wasted power during the roll forming of low-strength wear-resistant steel plates.

[0040] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0041] To save energy, such as Figure 1-4 As shown, the rolling mill for producing wear-resistant steel plates according to this utility model includes:

[0042] Frame 1 is provided with at least one set for supporting the rolling components;

[0043] Rolling section 2 is mounted on frame 1;

[0044] The power supply unit 3 is mounted on the frame 1 and connected to the rolling section 2;

[0045] Surface treatment section 4.

[0046] In use, the machine frame 1, the rolling section 2, the power supply section 3 and the surface treatment section 4 provide a rolling mechanism with power combination supply for wear-resistant steel plates made by the overlay welding process. It can use different rolling driving forces to perform rolling treatment with wear-resistant steel plates of different hardness and strength, realize flexible power supply, and effectively save power energy costs.

[0047] For example, such as Figure 1 As shown, the present invention also includes that the frames 1 are arranged at equal intervals, and the inlet and outlet ends of adjacent frames 1 are corresponding to each other, and the surface treatment part 4 is located at the inlet end of the first frame 1 arranged at equal intervals.

[0048] To improve the flatness of wear-resistant steel plates, for example, such as Figure 2 , 3 As shown, the present invention also includes, the rolling section 2, comprising:

[0049] Roller frame 201 is mounted on top of frame 1;

[0050] The lower roll 202 is located at the bottom of the roll frame 201;

[0051] The upper roll 203 is located on top of the lower roll 202.

[0052] In use, the wear-resistant steel plate passing between the lower roll 202 and the upper roll 203 is rolled by multiple sets of opposing lower rolls 202 and upper rolls 203, so that the wear-resistant steel plate has better flatness.

[0053] To distribute driving force, for example, such as Figure 2 , 3 As shown, the present invention also includes, the power supply unit 3 includes:

[0054] Motor 301 is mounted on frame 1;

[0055] The reducer 302 is mounted on the frame 1 and connected to the motor 301;

[0056] At least one set of first pulleys 303 is provided and connected to motor 301, reducer 302 and lower roller 202;

[0057] The second pulley 304 is mounted on the upper roller 203;

[0058] The lower gear 305 is mounted on the lower roll 202;

[0059] The upper gear 306 is mounted on the upper roller 203 and meshes with the lower gear 305.

[0060] In use, the motors 301 on multiple sets of frames 1 drive the corresponding first pulleys 303 to rotate, which in turn causes the corresponding reducers 302 to drive the lower rollers 202 to rotate. Based on the meshing of the lower gear 305 and the upper gear 306, the upper rollers 203 and the lower gear 305 rotate in opposite directions, thus performing rolling operations on the incoming wear-resistant steel plates.

[0061] For example, such as Figure 1 , 2 As shown, the present invention further includes the following: the first pulley 303 is connected to the drive shaft of the motor 301, the input shaft and output shaft of the reducer 302, and the shaft head of one end of the lower roller 202; the first pulley 303 of the drive shaft of the motor 301 is connected to the first pulley 303 on the input shaft of the reducer 302 via a belt; the first pulley 303 of the output shaft of the reducer 302 is connected to the first pulley 303 on the lower roller 202 via a belt; and the second pulleys 304 of the upper roller 203 are connected to each other via belts.

[0062] When in use, workers select the required number of motors 301 to work based on the strength of the wear-resistant steel plate. The higher the strength of the steel plate, the more motors 301 are turned on. If the strength of the steel plate is low, only some motors 301 are turned on, thereby achieving the effect of energy saving.

[0063] Based on the transmission of the second pulley 304 between the upper rolls 203, even if only one set of motors 301 is working, multiple sets of rolls on the frame 1 can be driven.

[0064] To improve quality, for example, such as Figure 1 , 4 As shown, the present invention also includes, the surface treatment part 4 includes:

[0065] Cabinet 401;

[0066] Through-hole 402 is opened through the cabinet 401;

[0067] Vacuum cleaner 403 is installed on cabinet 401 and located at the bottom of through-panel opening 402;

[0068] Air outlet 404 is located on the outside of cabinet 401.

[0069] The vacuum cleaner 403 has two sets of dust inlets, which are respectively located at the top and bottom of the through-plate opening 402.

[0070] During use, the wear-resistant steel plate passes through the through-hole 402, and the dust inlet of the vacuum cleaner 403 performs a suction operation at the top and bottom of the outlet 404, so that the debris on the surface of the wear-resistant steel plate passing through the outlet 404 is removed, thus cleaning the steel plate and improving the quality of the wear-resistant steel plate rolling process. This effectively prevents debris from being pressed onto the surface of the steel plate.

[0071] In use, the power supply components of the work site provide power to the electrical mechanism described in this application. During rolling, the wear-resistant steel plate to be rolled is fed into the through-hole 402 by workers or a conveyor. The wear-resistant steel plate passes through the through-hole 402 and enters between the lower roll 202 and the upper roll 203. The worker selects the required number of motors 301 to work according to the strength of the wear-resistant steel plate. The higher the strength of the steel plate, the more motors 301 are turned on. If the strength of the steel plate is low, only some motors 301 are turned on. Based on the transmission of the second pulley 304 between the upper rolls 203, even if only one set of motors 301 is working, multiple sets of rolls on the frame 1 can be driven. The motors 301 drive the corresponding first pulley 303 to rotate, which causes the corresponding reducer 302 to drive the lower roll 202 to rotate. Based on the meshing of the lower gear 305 and the upper gear 306, the upper roll 203 and the lower gear 305 rotate in opposite directions, thus performing the rolling operation on the incoming wear-resistant steel plate.
