Description

Technical Field

[0001] The invention relates to the technical field of metal rolling equipment, and in particular to a metal rolling equipment for processing a bridge body of a bridge frame. Background Art

[0002] The production process of stainless steel horizontal bridge is complex, including multiple steps such as material selection, processing, manufacturing, surface treatment and assembly. Among them, the rolling process is an important link in its production and is indispensable. Through hot rolling and cold rolling processes, stainless steel plates are made into steel plates or steel strips with specific thickness and width. These steel plates are further processed into basic components of the bridge; The metal rolling equipment used for the bridge body processing of the current bridge frame is found to have at least the following technical problems: First, the metal materials currently used to manufacture bridges may have oxide scale, rust or other impurities, which not only affect the appearance quality of the product, but may also be pressed into the metal during the rolling process, causing product quality problems such as surface defects and reduced strength.

[0003] Second, currently when the stainless steel plate is transported, there is no mechanism for positioning it on the conveyor, which causes the stainless steel plate to move easily and cannot enter the rolling mill forward, thereby reducing the rolling effect.

[0004] Third, when stainless steel is cold rolled, due to its high deformation resistance and tendency to work hardening, the use of appropriate lubricants can effectively reduce the friction coefficient, reduce rolling pressure and improve the surface quality of the strip. The current rolling equipment does not have a mechanism for applying lubricants, and it needs to be operated before rolling, which greatly reduces the efficiency of palm oil coating.

Two extension blocks 26 are fixedly mounted on the push-pull rod 23, and trapezoidal long rods 27 are fixedly mounted on the two extension blocks 26. The two trapezoidal long rods 27 are respectively penetrated and slidably mounted in the rectangular holes 18 provided in the two lifting rods 14, and the stainless steel When processing the steel bridge frame, the stainless steel plate needs to be rolled first, and the equipment is used for rolling the stainless steel plate. When in use, the stainless steel plate is placed on the object roller conveyor 31, and the conveying rollers on the object roller conveyor 31 will convey the stainless steel plate. The left ends of the movable side plate 21 and the fixed side plate 32 in the equipment are both rounded, which can guide the stainless steel plate and prevent the stainless steel plate from being stuck with the side of the object roller conveyor 31. When conveying, the stainless steel plate will first pass between the two brush fixing rods 25, and the two brush fixing rods 25 will pass through the two brush fixing rods 25. Brushes are provided on opposite sides of the brush fixing rods 25. The present invention arranges two brush fixing rods 25 on the movable side plate 21, so that when the equipment is conveying the stainless steel plate, the brushes on the two brush fixing rods 25 will clean the oxide scale, oil stains, dust and other impurities on the stainless steel plate, so as to avoid these impurities from being embedded in the metal or affecting the surface quality of the product during rolling, thereby improving the quality of the stainless steel plate after rolling. The left end of the movable side plate 21 is made of a deformable material, so that it can be bent at any time.

[0021] Two scrapers 24 are provided on the movable side plate 21, and two brush fixing rods 25 are provided on the movable side plate 21. The brush fixing rod 25 is located on the left side of the scraper 24. A guide rod 12 is fixedly installed at the bottom of the inner wall of the lubricating oil tank 11. The connecting plate 15 penetrates and is slidably installed on the circumferential surface of the guide rod 12. When the stainless steel plate passes through the distance sensor 44 on the movable side plate 21 (the distance sensor 44 is a mature technology in the prior art, and the distance sensor 44 is connected to the control box, the PLC controller and the cylinder 33 through the currently known connection method), the distance sensor 44 will transmit a signal to the control box under the recognition, and the control box will control the control box through the PLC controller. The cylinder 33 is controlled so that the cylinder 33 drives the telescopic rod 34 to move, and the telescopic rod 34 drives the movable side plate 21 to move, and under the action of the distance measuring sensor 44, the movable side plate 21 will be attached to one side of the stainless steel plate. At this time, the other side of the stainless steel plate is attached to the fixed side plate 32, so that the stainless steel plate can be input and positioned. The present invention uses a movable side plate 21 set at the upper end of the object roller conveyor 31, so that the device can correct the position of the stainless steel plate before conveying the stainless steel plate to the two rollers, so that it can enter the two rollers in the positive direction for rolling, thereby effectively improving the rolling effect.

[0022] Two springs 13 are fixedly installed on the upper end of the connecting plate 15, and an upper cover 51 is fixedly installed on the upper end of the lubricating oil tank 11. The upper cover 51 is provided with a refueling port 52. The upper ends of the two springs 13 are fixedly installed on the lower end of the upper cover 51. When the movable side plate 21 moves toward the fixed side plate 32, the heightening rod 22 and the push-pull rod 23 at the upper end of the movable side plate 21 will also move. At this time, the push-pull rod 23 will drive the two extension blocks 26 to move, and the two extension blocks 26 will drive the two trapezoidal long rods 27 to move. At this time, the two trapezoidal long rods 27 will pass through the rectangular hole 18 opened by the lifting rod 14, squeeze the lifting rod 14, and move it upward. When the two lifting rods 14 move upward, the two lifting rods 14 drive the connecting plate 15 and the multiple blocking blocks 16 at the lower end thereof to move upward. At this time, the blocking blocks 16 will be opened from the lubricating oil tank 11. The palm oil added into the lubricating oil tank 11 from the refueling port 52 will flow from the oil dripping hole 17 onto the stainless steel plate, thereby improving the rolling of the stainless steel plate. The present invention adopts the lubricating oil tank 11 arranged on the fixed side plate 32 and the linkage structure between the movable side plate 21 and the lubricating oil tank 11, so that the palm oil can be coated on the surface of the stainless steel plate while the stainless steel plate is positioned and moved, thereby effectively reducing friction and wear, reducing rolling pressure, improving the rolling efficiency of the stainless steel plate and the surface quality of the strip, and improving the efficiency of palm oil coating while the stainless steel plate is positioned and moved. When the cylinder 33 drives the movable side plate 21 back to its original position, the two lifting rods 14 will return to their original position under the extrusion of the spring 13, thereby blocking the oil dripping hole 17 through the blocking block 16.

[0023] A convex groove 41 is provided on the object roller conveyor 31, a T-shaped block 42 is slidably sleeved in the convex groove 41 provided on the object roller conveyor 31, a rotating rod 43 is fixedly installed on the T-shaped block 42, the left end of the movable side plate 21 is rotatably connected with the rotating rod 43, a distance measuring sensor 44 is provided at the front end of the movable side plate 21, a telescopic rod 34 is fixedly installed at the rear end of the movable side plate 21, a cylinder 33 is provided at the rear end of the telescopic rod 34, and the cylinder 33 is fixedly installed on the object roller conveyor 31. When the movable side plate 21 moves, the left end of the movable side plate 21 is rotatably installed on the T-shaped block 42 and the rotating rod 43, and the T-shaped block 42 can be in the convex groove 41 provided on the object roller conveyor 31. 1, so when the movable side plate 21 moves, the position of the movable side plate 21 is still in contact with the side of the object roller conveyor 31, and will not be far away from the object roller conveyor 31, so that the next stainless steel plate to be conveyed can continue to be guided, and the transportation of the next stainless steel plate will not be affected by the movement of the movable side plate 21. In the present invention, after palm oil is added to the stainless steel plate, the stainless steel plate will continue to move toward the direction of the scraper 24. At this time, under the contact between the scraper 24 and the stainless steel plate, the palm oil on the stainless steel plate will be evenly spread, so that the friction and wear between the stainless steel plate and the roller are reduced, and the rolling efficiency of the stainless steel plate and the surface quality of the strip are further improved.

[0024] Working principle: The first step is to roll the stainless steel plate when processing the stainless steel bridge frame. The equipment is used to roll the stainless steel plate. When in use, the stainless steel plate is placed on the object roller conveyor 31. The conveying rollers on the object roller conveyor 31 will convey the stainless steel plate. The left ends of the movable side plate 21 and the fixed side plate 32 in the equipment are both rounded, which can guide the stainless steel plate and prevent the stainless steel plate from getting stuck with the side of the object roller conveyor 31. When conveying, the stainless steel plate will first pass through the two brush fixing rods 25. However, brushes are provided on the opposite surfaces of the two brush fixing rods 25. The present invention uses two brush fixing rods 25 arranged on the movable side plate 21, so that when the equipment is conveying the stainless steel plate, the brushes on the two brush fixing rods 25 will clean the oxide scale, oil stains, dust and other impurities on the stainless steel plate to avoid these impurities from being embedded in the metal or affecting the surface quality of the product during rolling, thereby improving the quality of the stainless steel plate after rolling. The left end of the movable side plate 21 is made of a deformable material, so that it can be bent at any time.

[0025] In the second step, when the stainless steel plate passes through the distance sensor 44 on the movable side plate 21 (the distance sensor 44 is a mature technology in the prior art, and the distance sensor 44 is connected to the control box, the PLC controller and the cylinder 33 by a connection method currently known), the distance sensor 44 will transmit a signal to the control box under the recognition, and the control box will control the cylinder 33 through the PLC controller, so that the cylinder 33 drives the telescopic rod 34 to move, and the telescopic rod 34 will drive the movable side plate 21 to move, and under the action of the distance sensor 44, the movable side plate 21 will be attached to one side of the stainless steel plate, and the other side of the stainless steel plate will be attached to the fixed side plate 32, so that the stainless steel plate can be input and positioned. The present invention uses a movable side plate 21 set at the upper end of the object roller conveyor 31, so that the device can correct the position of the stainless steel plate before conveying it to the two rollers, so that it can enter the two rollers in a positive direction for rolling, thereby effectively improving the rolling effect.

[0026] In the third step, while the movable side plate 21 moves toward the fixed side plate 32, the heightening rod 22 and the push-pull rod 23 at the upper end of the movable side plate 21 will also move. At this time, the push-pull rod 23 will drive the two extension blocks 26 to move, and the two extension blocks 26 will drive the two trapezoidal long rods 27 to move. At this time, the two trapezoidal long rods 27 will pass through the rectangular hole 18 opened by the lifting rod 14, squeeze the lifting rod 14, and move it upward. When the two lifting rods 14 move upward, the two lifting rods 14 drive the connecting plate 15 and the multiple blocking blocks 16 at the lower end thereof to move upward. At this time, the blocking block 16 will be moved out of the oil dripping hole 17 opened in the lubricating oil tank 11, and at this time, the palm oil added to the inside of the lubricating oil tank 11 from the refueling port 52 will be filled. The oil will flow from the oil dripping hole 17 onto the stainless steel plate, thereby improving the rolling of the stainless steel plate. The present invention uses a lubricating oil tank 11 set on the fixed side plate 32 and a linkage structure between the movable side plate 21 and the lubricating oil tank 11, so that palm oil can be coated on the surface of the stainless steel plate while the stainless steel plate is positioned and moved, thereby effectively reducing friction and wear, reducing rolling pressure, improving the rolling efficiency of the stainless steel plate and the surface quality of the strip, and improving the efficiency of palm oil coating while the stainless steel plate is positioned and moved. When the cylinder 33 drives the movable side plate 21 back to its original position, the two lifting rods 14 will return to their original position under the extrusion of the spring 13, thereby blocking the oil dripping hole 17 through the blocking block 16.

[0027] In the fourth step, when the movable side plate 21 moves, the left end of the present invention is rotatably mounted on the T-block 42 and the rotating rod 43, and the T-block 42 can move in the convex groove 41 opened in the object roller conveyor 31. Therefore, when the movable side plate 21 moves, the position of the movable side plate 21 is still in contact with the side of the object roller conveyor 31 and will not move away from the object roller conveyor 31, so that the next stainless steel plate to be conveyed can continue to be guided, and the transportation of the next stainless steel plate will not be affected by the movement of the movable side plate 21.

[0028] In the fifth step, after palm oil is added to the stainless steel plate, the stainless steel plate will continue to move toward the scraper 24. At this time, the palm oil on the stainless steel plate will be evenly spread under the contact between the scraper 24 and the stainless steel plate, thereby reducing the friction and wear between the stainless steel plate and the roller, further improving the rolling efficiency of the stainless steel plate and the surface quality of the strip.

[0029] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
