Description

Technical Field

[0001] This utility model relates to the field of steel production technology, specifically to a billet shearing machine with adjustable shearing length. Background Technology

[0002] Steel billets are the product obtained after casting molten steel produced in a steelmaking furnace. They are generally not directly available for market use and require further processing to become the final product. Steel billets are mainly used to produce various steel products. They come in various shapes, commonly including slabs, square billets, and rectangular billets. Square and rectangular billets can be rolled into structural steel, while slabs can be rolled into plates and used in the production of steel products, machine parts, and forgings. Therefore, as a semi-finished product in steel production, steel billets are an important raw material for the steel industry. During processing, steel billets need to be sheared to remove defects or meet specified length requirements, which necessitates the use of a billet shearing machine.

[0003] Patent CN210996882U discloses a billet shearing machine, including a worktable and a housing. The housing is located on one side of the upper part of the worktable, and a support is provided on the upper part of the worktable near the housing. An upper pressure shaft and a lower pressure shaft are respectively installed at the upper and lower ends of the support. One end of the upper and lower pressure shafts extends into the outside of the support and is fitted with a gear. The end of the lower pressure shaft away from the gear is installed at the front end of a servo motor. A telescopic rod is provided at the upper part of the housing and is fixedly installed on the upper side of the housing with bolts. A motor is installed at the bottom end of the telescopic rod, which is located inside the housing, and is fixedly installed at the bottom end of the telescopic rod with bolts. A cutting wheel is installed at the front end of the motor. In use, the servo motor drives the upper and lower pressure shafts to move the billet forward. The servo motor is controlled by an encoder, which can control the number of revolutions of the servo motor, thereby controlling the forward conveying length of the billet.

[0004] Although the above-mentioned device controls the conveying length of the steel billet using a servo motor, it still has the following shortcomings:

[0005] Steel billets come in a variety of shapes, including slabs, square billets, round billets, and rectangular billets. Their widths and heights vary. The distance between the upper and lower pressure shafts of the aforementioned device is fixed and cannot be adjusted according to the shape of the steel billet, thus limiting its applicability. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a billet shearing machine with adjustable shearing length, which can adjust the shearing length of various billets.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a billet shearing machine with adjustable shearing length, comprising a transport roller conveyor, the transport roller conveyor comprising limit frames on both sides and a conveying roller disposed between the limit frames, a plurality of roller conveyor limit components disposed on the inner side of the limit frames above the conveying roller, a pressing and fixing component disposed above the transport roller conveyor, a pressure roller counting component disposed at the end of the transport roller conveyor, and a fitted laser cutting component disposed behind the pressure roller counting component.

[0008] Furthermore, the roller conveyor limiting assembly includes a lateral concave plate disposed inside the limiting frame, an electric telescopic rod extending to the outside of the limiting frame is disposed at the rear end of the lateral concave plate, and a horizontally rotating limiting wheel is disposed between the inner front ends of the lateral concave plate.

[0009] Furthermore, the pressing and fixing assembly includes a pressing placement frame disposed above the limiting frame. The pressing placement frame is disposed between the last two roller limit assemblies. A hydraulic telescopic rod penetrating the top surface is disposed in the middle of the pressing placement frame. A pressing fixing plate is disposed on the bottom surface of the hydraulic telescopic rod. A pressing pad is bolted to the bottom surface of the pressing fixing plate.

[0010] Furthermore, the pressure roller counting assembly includes a pressure roller plate disposed at the end of the limiting frame, a fixed roller with the same top surface height as the top surface of the conveying roller disposed between the pressure roller plates, a lead screw vertically rotatably connected to the pressure roller plate, a lifting drive motor connected to the lead screw disposed on the bottom surface of the pressure roller plate, a lifting block rotatably connected to the upper end of the lead screw, a rotating shaft disposed between the lifting blocks, a lower pressure roller disposed on the outer side of the rotating shaft, a laser indicator disposed on the outer side of both ends of the lower pressure roller, and a laser counter disposed on the lifting block in cooperation with the laser indicator.

[0011] Furthermore, the laser cutting assembly includes a laser placement frame, a placement groove on the top surface of the laser placement frame, a movable block inside the placement groove, a laser cutter on the bottom surface of the movable block, a threaded rod connected to the movable block for lateral rotation, and a movement drive motor at the end of the threaded rod.

[0012] Furthermore, a laser indicator 2 is provided on the outer side of the upper end of the limiting wheel, and a laser counter 2 that cooperates with the laser indicator 2 is provided on the top surface of the limiting placement frame.

[0013] Furthermore, auxiliary rollers are provided at both ends of the upper surface of the lower end of the laser placement frame, and a collection groove is opened between the auxiliary rollers in the laser placement frame. A collection box communicating with the collection groove is provided on the bottom surface of the laser placement frame.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. By setting roller limit components on the conveyor rollers, steel billets of different widths can be limited during transportation, allowing them to move in a straight line; by setting down-fixing components, the steel billets can be fixed by down-pressing when they reach a designated position, making them ready for cutting; by setting pressure roller counting components, as the steel billets pass through, the rotating pressure rollers are counted with the cooperation of a laser indicator and a laser counter. By combining this with the fixed diameter of the pressure rollers, the length of the steel billets that have passed through can be obtained, thus allowing the cutting length to be adjusted as needed.

[0016] 2. By setting a laser indicator on the limit wheel and a matching laser counter on the limit placement frame, the length of the conveyed steel billet can be calculated by calculating the fixed diameter and number of rotations of the limit wheel. The accuracy of the shearing length can be further improved by cooperating with the pressure roller counting assembly. By setting a collection groove and collection box at the lower end of the laser placement frame, the debris cut by the laser can be collected to prevent the debris from affecting the shearing of the steel billet.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] like Figures 1 to 5 As shown, an adjustable shearing length billet shearing machine includes a transport roller conveyor 1. The transport roller conveyor 1 includes limit frames 101 on both sides and a conveying roller 102 disposed between the limit frames 101. Several roller conveyor limit components 2 are disposed on the inner side of the limit frames 101 above the conveying roller 102. A pressing and fixing component 3 is disposed above the transport roller conveyor 1. A pressure roller counting component 4 is disposed at the end of the transport roller conveyor 1. A fitted laser cutting component 5 is disposed behind the pressure roller counting component 4.

[0025] like Figure 1 As shown, the billet shearing machine of this utility model is structurally similar to existing billet shearing machines. For example, patent CN210996882U discloses a billet shearing machine. The main improvement of this utility model is that it can adjust the shearing length of various billets, such as... Figures 1 to 5As shown, in this utility model, an adjustable shearing length billet shearing machine first selects a suitable lower pressure pad 304 according to the shape and size of the billet and installs it on the lower pressure fixing plate 303. Then, the lifting drive motor 404 is controlled to rotate the screw 403, so that the lower pressure roller 407 moves to a suitable height, ensuring contact with the billet without hindering its forward movement. Subsequently, the electric telescopic rod 202 is controlled to move the lateral concave plate 201, so that the distance between the limiting wheels 203 is the same as the width of the billet, thereby limiting the billet. After the preparation work is completed, the conveying roller 102 will transport the billet, which will move in a straight line under the clamping of the limiting wheels 203 and enter the pressure roller counting assembly 4. At this time, the billet will drive the lower pressure roller 407 to rotate, and the laser indicator 6 on the lower pressure roller 407 will also rotate. The laser counter 7 on the lifting block 405 will cooperate with the laser indicator 6 to monitor the lower pressure roller. The number of rotations of the 407 is counted, which, in conjunction with the laser counter 9 on the side concave plate 201, allows for precise determination of the billet's passing length. Simultaneously, the laser indicator 8 on the limit wheel 203, in conjunction with the laser counter 9 on the side concave plate 201, counts the rotations of the limit wheel 203. By calculating the fixed diameter and rotation count of the limit wheel 203, the length of the conveyed billet can also be calculated and compared with the data calculated by the pressure roller counting assembly 4, thereby further improving data accuracy. When the billet entering the laser cutting assembly 5 reaches the required length, the hydraulic telescopic rod 302 is extended or retracted, causing the pressure pad 304 fixed on the pressure fixing plate 303 to press downwards to fix the billet. At this time, the moving drive motor 506 is controlled to move the moving block 503 on the threaded rod 505 back and forth, allowing the laser cutter 504 to move left and right to cut the billet, achieving billet shearing.

[0026] like Figure 2 and Figure 3 As shown, the roller conveyor limiting assembly 2 includes a lateral concave plate 201 disposed inside the limiting frame 101, an electric telescopic rod 202 extending to the outside of the limiting frame 101 is disposed at the rear end of the lateral concave plate 201, and a horizontally rotating limiting wheel 203 is disposed between the inner front ends of the lateral concave plate 201.

[0027] Specifically, by controlling the electric telescopic rod 202 to move the lateral concave plate 201 left and right, the limiting wheel 203 on the lateral concave plate 201 can clamp and limit the billet, allowing it to move forward in a straight line. At the same time, the rolling limiting wheel 203 can prevent the billet from continuing to move forward when facing smaller pressure.

[0028] like Figure 1 and Figure 2As shown, the pressing and fixing assembly 3 includes a pressing placement frame 301 disposed above the limiting frame 101. The pressing placement frame 301 is disposed between the last two roller limit assemblies 2. A hydraulic telescopic rod 302 is disposed through the middle of the top surface of the pressing placement frame 301. A pressing fixing plate 303 is disposed on the bottom surface of the hydraulic telescopic rod 302. A pressing pad 304 is bolted to the bottom surface of the pressing fixing plate 303.

[0029] Specifically, by setting up a pressure placement frame 301, when the steel billet needs to be sheared, the hydraulic telescopic rod 302 will extend and retract, causing the pressure pad 304 fixed on the pressure fixing plate 303 to press down and fix the steel billet. When facing different types of steel billets, the pressure pad 304 can be replaced to adapt to the shape of the steel billet and ensure the fixation of the steel billet.

[0030] like Figure 5 As shown, the pressure roller counting assembly 4 includes a pressure roller plate 401 disposed at the end of the limiting frame 101. A fixed roller 402 with the same top surface height as the top surface of the conveying roller 102 is disposed between the pressure roller plates 401. A lead screw 403 is vertically rotatably connected to the pressure roller plate 401. A lifting drive motor 404 connected to the lead screw 403 is disposed on the bottom surface of the pressure roller plate 401. A lifting block 405 is rotatably connected to the upper end of the lead screw 403. A rotating shaft 406 is disposed between the lifting blocks 405. A lower pressure roller 407 is disposed on the outer side of the rotating shaft 406. Laser indicators 6 are disposed on the outer sides of both ends of the lower pressure roller 407. A laser counter 7 that cooperates with the laser indicators 6 is disposed on the lifting block 405.

[0031] Specifically, based on the type and size of the steel billet, the lifting drive motor 404 is controlled to rotate the lead screw 403, causing the lifting block 405 to drive the rotating shaft 406 and the lower pressure roller 407 to move up and down. When the height is appropriate, the lower pressure roller 407 will rotate as the steel billet passes through. At this time, the laser indicator 6 will also rotate. The laser counter 7 on the lifting block 405 will work with the laser indicator 6 to count the number of rotations of the lower pressure roller 407, thereby accurately determining the length of the steel billet passing through. With the fixing of the lower pressure fixing component 3, the shearing length can be adjusted.

[0032] like Figure 4 As shown, the laser cutting assembly 5 includes a laser placement frame 501, a placement groove 502 is provided on the top surface of the laser placement frame 501, a moving block 503 is provided in the placement groove 502, a laser cutter 504 is provided on the bottom surface of the moving block 503, a threaded rod 505 is rotatably connected to the moving block 503, and a moving drive motor 506 is provided at the end of the threaded rod 505.

[0033] Specifically, after the steel billet is transported to the appropriate position, the pressing and fixing component 3 will press down to fix the steel billet, then turn on the laser cutter 504, and then control the moving drive motor 506 so that the moving block 503 on the threaded rod 505 can move back and forth, thereby allowing the laser cutter 504 to move left and right to cut the steel billet and realize the shearing of the steel billet.

[0034] like Figure 3 As shown, a laser pointer 28 is provided on the outer side of the upper end of the limiting wheel 203, and a laser counter 29 that cooperates with the laser pointer 28 is provided on the top surface of the side concave plate 201.

[0035] Specifically, by setting a laser indicator 28 on the limiting wheel 203, the number of rotations of the limiting wheel 203 can be counted during the transport of the steel billet, in conjunction with the laser counter 29 set on the side concave plate 201. By calculating the fixed diameter and the number of rotations of the limiting wheel 203, the length of the transported steel billet can be calculated, and the accuracy of the shearing length can be further improved in conjunction with the pressure roller counting assembly 4.

[0036] like Figure 4 As shown, the upper surface of the lower end of the laser placement frame 501 is provided with auxiliary rollers 507 at both ends, and the laser placement frame 501 between the auxiliary rollers 507 is provided with a collection groove 508, and the bottom surface of the laser placement frame 501 is provided with a collection box 509 that communicates with the collection groove 508.

[0037] Specifically, by setting auxiliary rollers 507, the steel billet can be fed into the laser placement frame 501 to prevent the steel billet from colliding with the laser placement frame 501. A collection groove 508 is opened in the laser placement frame 501 between the auxiliary rollers 507, and together with the collection box 509, the debris cut by the laser can be collected to prevent the debris from affecting the shearing of the steel billet.

[0038] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
