Description

Technical Field

[0001] The utility model relates to the technical field of square billet deburring, in particular to a three-roller pressing roller mechanism used in a square billet deburring device. Background Art

[0002] After a billet is cut by a flame cutting machine, burrs are generated on its lower surface. In the prior art, billet deburring is typically accomplished using devices such as scrapers and cleaning rollers. Typically, during the billet's transportation, the scraper or cleaning roller is lifted to support the billet's lower surface, and the billet is moved relative to the scraper to achieve deburring. For example, patent publication number CN212350642U discloses a reciprocating spring cutting and deburring machine for continuous casting billets. This machine utilizes the reverse rotation of a conveyor roller to drive the billet relative to the scraper to complete the deburring operation. However, in actual production, it has been found that if the lifting force of the scraper or other device is too great, the billet will be lifted from the conveyor rollers, causing it to disengage from the conveyor rollers, affecting the transportation of the billet. If the lifting force is reduced, burrs may not be completely removed.

[0003] In order to solve the above problems, the patent with authorization announcement number CN214108721U discloses a mechanism for removing burrs from the ends of square billets with front and rear pressure rollers. The device uses two front and rear pressure roller assemblies to press the running square billet, so that it runs smoothly and ensures that the bottom of the square billet is tightly fitted with the cleaning roller. However, the device uses the rotation of the cleaning roller to achieve deburring operation, and it is found in actual production that if a scraper is used in conjunction with the operation, when the square billet is input, since the rear part of the square billet is still in the flame cutting machine and other equipment, the square billet generally will not warp up, etc. After the billet is completely output, since there is no other equipment to limit the position, when the billet tail end is deburred, if only one side of the pressure roller and scraper in the above-mentioned CN214108721U patent are used in conjunction, the billet is prone to slight warping, etc., which will cause the billet to be not flat enough, thereby affecting the deburring quality.

[0011] 1. The utility model positions the billet through a three-roller pressing mechanism, which can ensure that the lower side of the head end or tail end of the billet is in full contact with the scraper, thereby ensuring the quality of deburring. When the head end of the billet is deburred, the first roller in the pressing mechanism presses the billet, and when the tail end of the billet is deburred, the second and third rollers in the pressing mechanism press the billet. In addition, considering that there is no equipment limit at the front of the billet after it is output, the third roller can press a position close to the middle of the billet, thereby cooperating with the second roller to ensure the flatness of the billet, thereby ensuring the quality of deburring at the tail end of the billet.

[0012] 2. The utility model provides a driving gear on the second hinge shaft at the connection between the second intermediate arm and the second swing arm, and a driven gear is provided on the third hinge shaft connecting the third swing arm and the upper end of the frame, and the driving gear drives the driven gear to rotate through the intermediate gear transmission torque, so that the swinging of the second swing arm can also drive the swinging of the third swing arm, thereby achieving the purpose of using one driving device to drive the second pressing roller and the third pressing roller to move, which will not increase the number of driving devices of the entire equipment, thereby ensuring that the manufacturing cost of the equipment is controllable, and the present invention can also achieve the purpose of the second pressing roller first contacting the upper surface of the square billet for positioning, and then the third pressing roller contacting the upper surface of the square billet for flattening through the design of the gear transmission ratio, the length of the second swing arm and the third swing arm.

DETAILED DESCRIPTION

[0018] The present invention will be further described below in conjunction with the accompanying drawings.

[0019] like Figures 1 to 3As shown, the utility model includes a first pressure roller assembly, a second pressure roller assembly and a frame 17, wherein the first pressure roller assembly is arranged on the input side of the frame 17 and includes a first pressure roller driving device 1, a first intermediate arm 2 and a first swing arm 4 which are hingedly connected in sequence, and a first pressure roller 5 is provided at the end of the first swing arm 4, and the second pressure roller assembly is arranged on the output side of the frame 17 and includes a third swing arm 15 and a second pressure roller driving device 6, a second intermediate arm 7 and a second swing arm 10 which are hingedly connected in sequence, wherein a second pressure roller 11 is provided at the end of the second swing arm 10, the second intermediate arm 7 and the second swing arm 10 are connected by a second hinge shaft 8, the third swing arm 15 is installed on the third hinge shaft 13, and a power transmission assembly is provided between the second hinge shaft 8 and the third hinge shaft 13 to transmit torque, and a third pressure roller 16 is provided at the end of the third swing arm 15.

[0020] When the utility model works, Figure 2 As shown, when deburring the lower side of the head end of the billet 19, the first pressing roller driving device 1 drives the first swing arm 4 to rotate downward through the first intermediate arm 2, thereby driving the first pressing roller 5 to press the head end of the billet 19. At this time, since the rear part of the billet 19 is still in the flame cutting machine and other equipment, it generally does not warp. Figure 3 As shown, when deburring the lower side of the tail end of the square billet 19, the second pressing roller driving device 6 drives the second swing arm 10 to rotate downward through the second intermediate arm 7, and then drives the second pressing roller 11 to press the tail end of the square billet 19. However, at this time, the square billet 19 has been completely output from the cutting machine, and there is generally no other equipment in front of it. Therefore, at this time, only relying on the cooperation of the second pressing roller 11 and the scraper 18, the square billet 19 is prone to slight warping and the like, and thus the square billet 19 cannot remain flat, which affects the deburring quality. Therefore, the utility model adds a third pressing roller 16 and a third swing arm 15. When the second swing arm 10 rotates, the torque can be transmitted through the power transmission component to drive the third swing arm 15 to rotate downward, so that the third pressing roller 16 at the end of the third swing arm 15 also presses the square billet 19, and as shown in FIG. Figure 3 As shown, the third swing arm 15 is longer than the second swing arm 10, which allows the third press roller 16 to be pressed near the middle of the billet 19. In this way, the present invention can ensure the flatness of the billet 19 during deburring through the combined action of the third press roller 16 and the second press roller 11, thereby ensuring the deburring quality. The first press roller drive device 1 and the second press roller drive device 6 can be devices such as hydraulic cylinders.

[0021] like Figure 1 As shown, in this embodiment, a first bracket 1701 is provided on one side of the upper end of the frame 17, and a second bracket 1702 is provided on the other side. The first intermediate arm 2 and the first swing arm 4 are connected through a first hinge shaft 3, and the first hinge shaft 3 is installed on the first bracket 1701, and the second hinge shaft 8, the power transmission assembly and the third hinge shaft 13 are all provided on the second bracket 1702.

[0022] like Figure 1 As shown, in this embodiment, the power transmission assembly includes a sequentially meshed drive gear 9, an intermediate gear 12, and a driven gear 14. The drive gear 9 is mounted on the second hinge shaft 8, and the driven gear 14 is mounted on the third hinge shaft 13. The number of intermediate gears 12 can be adjusted based on actual needs. In this embodiment, the second press roller 11 first contacts the upper surface of the billet 19 for positioning, and then the third press roller 16 contacts the upper surface of the billet 19 for flattening, by designing the gear ratio, the length of the second swing arm 10, and the third swing arm 15.

[0023] like Figures 1 to 3 As shown, in this embodiment, a scraper 18 that can be raised and lowered is provided inside the frame 17. Figure 2 and Figure 3 As shown, when removing burrs, the scraper 18 rises and abuts against the head end or tail end of the billet 19. In this embodiment, a lifting hydraulic cylinder or other device can be provided inside the frame 17 to drive the scraper 18 to rise and fall, which is a well-known technology in the art.

[0024] The working principle of this utility model is:

[0025] When the present invention is working, the billet 19 is driven into the frame 17 of the present invention through the transmission roller 20, wherein Figure 2 As shown, when deburring the lower side of the head end of the billet 19, the first pressing roller driving device 1 drives the first swing arm 4 to rotate downward through the first intermediate arm 2, thereby driving the first pressing roller 5 to press the head end of the billet 19, and the scraper 18 in the frame 1 rises and contacts the lower side of the head end of the billet 19, so that the first pressing roller 5 can ensure that the lower side of the head end of the billet 19 is in full contact with the scraper 18, and then the billet 19 is driven by the conveying roller 20 to move relative to the scraper 18, or the scraper 18 itself moves relative to the billet 19 to complete the deburring operation on the lower side of the head end of the billet 19. As shown in FIG. Figure 3 As shown, when deburring the lower side of the tail end of the billet 19, the second pressing roller driving device 6 drives the second swing arm 10 to rotate downward through the second intermediate arm 7, and then drives the second pressing roller 11 to press the tail end of the billet 19. When the second swing arm 10 rotates, the torque can be transmitted through the power transmission assembly composed of the driving gear 9, the intermediate gear 12 and the driven gear 14 to drive the third swing arm 15 to rotate downward, and then the third pressing roller 16 at the end of the third swing arm 15 also presses the billet 19, so as to ensure that the billet 19 is flat and will not warp, thereby ensuring the quality of deburring. The scraper 18 in the frame 1 rises and contacts the lower side of the tail end of the billet 19 and fully contacts it. Then the billet 19 is driven by the transmission roller 20 to move relative to the scraper 18, or the scraper 18 itself moves relative to the billet 19 to complete the deburring operation on the lower side of the head end of the billet 19.
