[0025] Example 1
[0026] A head-aligning device, such as Figure 1 As shown, it includes a mounting platform, on which two parallel push rod support seats 5 are fixed, and a push rod 7 that can move in the horizontal direction is provided in the push rod support seat 5. The two ends of the two push rods 7 are respectively connected to the same push head 1 and the same push plate 8. The push head 1 is arranged parallel to the push plate 8, and a driving mechanism is provided on the side of the push plate 8 away from the push rod support seat 5; guide rails 17 are fixed on both sides of the push head 1 in the horizontal direction, and guide wheels 4 cooperating with the guide rails 17 are provided at both ends of the push head 1.
[0027] The driving mechanism in this embodiment uses a hydraulic cylinder 12 with ear shafts on both sides. The side wall of the push plate 8 away from the push rod support seat 5 is connected to the connecting seat 10 by bolts. The ear ring at the end of the hydraulic cylinder 12 is connected to the connecting seat 10 by a first pin shaft 11. A hydraulic cylinder support seat 14 is fixed to the mounting platform. Two first copper sleeves 13 are symmetrically mounted on the hydraulic cylinder support seat 14. The ear shafts on both sides of the hydraulic cylinder 12 are mounted in the first copper sleeves 13 to position the hydraulic cylinder 12 in the front and back and left and right directions. The piston rod of the hydraulic cylinder 12 moves in the horizontal direction, thereby driving the push plate 8, push rod 7 and push head 1 to move in the horizontal direction. A valve station 15 is provided on the mounting platform. The energy medium provided by the valve station 15 and the pipeline 16 enables the piston rod of the hydraulic cylinder 12 to push out and retract to realize the forward and backward movement of the push head 1.
[0028] The push rod 7 is fixed to the push head 1 by a bolt. A threaded hole is provided on the push plate 8, and a threaded groove is provided at the end of the push rod 7 to match the threaded hole. After the push plate 8 and the push rod 7 are threadedly connected, they are fixed with a fastening nut 9.
[0029] The push plate 8 and the push head 1 are both rectangular in cross-section. The push rod 7 passes through the push rod support seat 5 and moves in the push rod support seat 5. The push rod support seat 5 performs radial positioning and axial guidance on the push rod 7.
[0030] like Figure 2 and Figure 3 As shown, the push rod support seat 5 comprises an upper body 502 and a lower body 501. The lower body 501 and the upper body 502 are connected by bolts 506. Bolt holes 5011 are provided at both ends of the lower body 501, which are secured to the mounting platform via bolts. A second copper sleeve 503 is installed between the lower body 501 and the upper body 502. The second copper sleeve 503 is sleeved around the outside of the push rod 7. The push rod support seat 5 in this embodiment utilizes a split bearing seat commonly used in the prior art, replacing the bearing with a second copper sleeve 503. The second copper sleeve 503 is a split copper sleeve, and seals 504 are provided at both ends of the second copper sleeve 503. The seals 504 are secured with split glands 505.
[0031] A first oiling hole 5021 is provided at the top of the upper body 502, and a second oiling hole 5031 is provided on the second copper sleeve 503, communicating with the first oiling hole 5021. An oiling tank 6 is provided at the top of the upper body 502, and an oil outlet pipe 601 is provided at the outlet of the oiling tank 6, which is threadedly connected to the first oiling hole 5021. Lubricating oil is contained in the oiling tank 6, and the lubricating oil flows from the oil outlet pipe 601 through the first oiling hole 5021 and the second oiling hole 5031, landing on the push rod 7. This reduces friction between the push rod 7 and the second copper sleeve 503, allowing the push rod 7 to move within the push rod support 5. The second copper sleeve 503 and the pressure cover 505 are both split to facilitate the inspection and maintenance of the equipment; the use of the seal 504 can store the lubricating grease supplied by the oil filling tank 6 in the push rod support seat 5, so that the push rod 7 can be better lubricated when moving in the push rod support seat 5. At the same time, the debris and iron dioxide on the exposed part of the push rod 7 can be cleaned to prevent them from entering the second copper sleeve 503, thereby reducing the movement wear of the spare parts.
[0032] The top of the oil filling tank 6 is provided with a filling hole 603, and a sealing cover is provided at the filling hole 603 for adding lubricating oil to the tank. A filter 602 is installed at the oil outlet of the oil filling tank 6, and the filter 602 adopts a conventional lubricating oil filter.
[0033] Guide wheel mounting bases 3 are fixed to each end of the pusher head 1. Guide wheels 4 are connected to these mounting bases via second pins 2. During installation, the central axis of the guide wheels 4 is perpendicular to the plane of the pusher head 1. In this embodiment, the guide wheels 4 utilize U-grooved guide wheels. When the hydraulic cylinder 12 is activated, the pusher head 1 reciprocates, and the guide wheels 4 move along the guide rails 17, guiding the pusher head 1 horizontally. The guide wheels 4 and guide rails 17, in conjunction with the push rod support base 5, provide dual guidance, thereby enhancing the structural rigidity of the device and increasing the reliability and stability of the pusher head 1 when unevenly loaded.
[0034] The furnace opening of conventional billet heating furnaces is equipped with a placement plate, one end of which is mounted with a trimming baffle. Billets are moved onto the placement plate via rollers, where they violently impact the trimming baffle during movement, achieving trimming. When installing the trimming device provided in this embodiment, the mounting platform is installed on the side of the original placement plate opposite the trimming baffle. Simultaneously, the original billet-moving rollers at the furnace opening are relocated to the side of the furnace opening. This optimizes the roller operating environment, increases the lifespan of the rollers and trimming baffle, and reduces the maintenance cost of production-related spare parts.
[0035] When the end trimming device provided by the utility model is used, Figure 1As shown, the steel billet 18 is transferred from the roller conveyor to the placement plate, and the hydraulic cylinder 12 is started to drive the push plate 8, the push rod 7 and the push head 1 to move back and forth. The push head 1 pushes the tail of the steel billet 18 to move until the tails of multiple steel billets 18 are in contact with the push head 1, completing the alignment operation.
[0036] Example 2
[0037] A trimming device, the technical solution in this embodiment is basically the same as that in embodiment 1, except that: a baffle 507 is provided at the first oil filling hole 5021 in this embodiment to facilitate intermittent addition of lubricating oil to the inside of the push rod support seat 5.
[0038] like Figure 4 As shown, a baffle 507 is provided in the first oil filling hole 5021, and the side wall of the baffle 507 is fixed to the L-shaped connecting rod 508. A first slide groove 5022 communicating with the first oil filling hole 5021 is provided inside the upper seat body 502, and a second slide groove 5023 communicating with the first slide groove 5022 is provided on the top of the upper seat body 502. The horizontal section of the L-shaped connecting rod 508 is located in the first slide groove 5022, and the vertical section of the L-shaped connecting rod 508 is located in the second slide groove 5023; the horizontal section of the L-shaped connecting rod 508 moves horizontally along the first slide groove 5022, and at the same time drives the baffle 507 to slide horizontally along the first slide groove 5022; the vertical section of the L-shaped connecting rod 508 slides along the second slide groove 5023, and the top end of the vertical section of the L-shaped connecting rod 508 extends out of the upper seat body 502.
[0039] A spring 509 is disposed in the first chute 5022. One end of the spring 509 is secured to the sidewall of the first chute 5022, away from the first oil hole 5021, and the other end is secured to the vertical section of the L-shaped connecting rod 508. The spring 509 maintains the baffle 507 in the first oil hole 5021 under the elastic force of the spring 509. When lubrication of the push rod 7 is required, the vertical section of the L-shaped connecting rod 508 is slid to slide the baffle 507 from the first oil hole 5021 into the first chute 5022, connecting the first oil hole 5021 with the second oil hole 5031 and lubricating the push rod 7.
[0040] In this embodiment, the upper part of the first oil filling hole 5021 is circular and the lower part is square. The circular part is threadedly connected to the oil outlet pipe 601 of the oil filling tank 6, and the baffle 507 is located in the square part. The shape of the baffle 507 is square. At the same time, the second oil filling hole 5031 is also designed to be square.
[0041] The upper body 502 has a square slot 5024 inside that connects to the first oil inlet 5021. A protrusion is fixed to the end of the baffle 507 away from the L-shaped connecting rod 508. The protrusion inserts into the slot 5024. The protrusion and slot 5024 enhance sealing and prevent oil leakage when the device is not in operation. A sealing cover can be installed above the second chute 5023 to prevent impurities from falling into the second chute 5023.
[0042] The baffle 507 provided in this embodiment facilitates intermittent oil injection into the push rod support seat 5. When the head-aligning device is working, the staff can slide the L-shaped connecting rod 508 at intervals to make the baffle 507 slide into the first slide groove 5022, connect the first oil injection hole 5021 with the second oil injection hole 5031, and the lubricating oil in the oil injection tank 6 enters the push rod support seat 5 to lubricate the push rod 7. After adding a certain amount of lubricating oil, loosen the L-shaped connecting rod 508.
[0043] For more convenient use, an electric telescopic rod can also be installed on one side of the push rod support seat 5, and the telescopic end of the electric telescopic rod is connected to the vertical section of the L-shaped connecting rod 508, and the electric telescopic rod is used to control the sliding of the L-shaped connecting rod 508.
[0044] The end-aligning device provided by this utility model replaces the original roller friction-based movement of the billets with an axial hydraulic thrust mechanism. This eliminates the impact force generated by acceleration on the end-aligning baffle and rollers during billet movement, ensuring the stability and smoothness of billet movement. The modification of the end-aligning device also relocates the roller installation position from the original furnace mouth to the side of the furnace mouth, thereby optimizing the device's operating environment, effectively improving the stability and service life of the rollers and end-aligning baffles, reducing their use and maintenance costs, ensuring production continuity, and achieving better economic value.
