Description

Technical Field

[0001] The invention relates to a boosting device, in particular to a push-type deburring boosting machine suitable for a scraper-type deburring machine for a short fixed-length slab in steelmaking and continuous casting and a use method thereof. Background Art

[0002] At present, steelmaking and continuous casting slabs in various steel plants need to be cut into fixed lengths using a fire cutter. After cutting, the iron oxide burrs generated on the lower surface of the slab ends must be cleaned. When using a scraper-type deburring machine to remove burrs, due to the light weight, small inertia, and small friction driving force of the roller table of the short fixed-length slab, the resistance of the scraper to the slab cannot be overcome, and the slab is stuck at the scraper and cannot be deburred or removed from the line. In order to avoid the above phenomenon, a flat-push booster device for deburring short fixed-length slabs has been studied and designed. The deburring is completed by pushing the front and rear ends of the slab to overcome the resistance of the scraper. Summary of the invention

[0003] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide a push-type deburring booster and a method of use, which can effectively improve the deburring rate of short fixed-length slabs, operate smoothly and safely, and be easy to use and maintain.

[0004] To achieve the above object, the present invention is implemented through the following technical solutions:

[0005] A push-type deburring booster comprises a frame, a movable body, a pressure roller, a push rod, a lifting hydraulic cylinder, a traveling hydraulic cylinder, a track and a roller; the frame is mounted on the tracks on both sides of the deburring machine, and rollers are installed at the bottom of the frame; the traveling hydraulic cylinder is fixed on the track, and the traveling hydraulic cylinder pushes the frame to reciprocate; a lifting hydraulic cylinder and a slideway are fixed at both ends of the frame, and the piston rod of the lifting hydraulic cylinder is connected to the movable body, and the movable body can slide up and down along the slideway driven by the lifting hydraulic cylinder; pressure rollers and push rods are installed on both sides of the movable body, the pressure rollers are used to position the slab and increase the driving friction of the roller on the slab, and the push rods are used to push the slab to overcome the resistance of the scraper to remove burrs.

[0006] A small wheel is arranged at the bottom of the push rod.

[0007] The traveling hydraulic cylinders are arranged on both sides of the frame, with two traveling hydraulic cylinders arranged on each side, and piston rods of the traveling hydraulic cylinders are pressed against the frame to push the frame.

[0008] A method for using a push-type deburring booster comprises the following steps:

[0009] 1) After the short fixed-length slab is transported from the cutting area roller to the deburring area roller, the deburring machine detection and control system controls the roller to rotate and drive the slab forward, and the deburring machine scraper rises and is close to the lower surface of the slab; the movable body descends along the slide, and the rollers and push rods on both sides of the movable body press on the upper surface of the slab at the same time;

[0010] 2) When the front end of the slab approaches the center of the booster, the roller on one side of the movable body is suspended, and the push rod on one side descends to the front end of the slab. The frame moves in the same direction as the slab under the drive of the traveling hydraulic cylinder. The push rod and roller table linked with the frame jointly drive the slab to overcome the resistance of the scraper to remove burrs. After the deburring work is completed, the scraper of the deburring machine descends, and the movable body rises to its original position under the drive of the lifting hydraulic cylinder;

[0011] 3) The roller rotates to drive the slab forward. When the tail end of the slab approaches the center of the booster, the movable body descends along the slide, the pressure roller on the other side of the movable body is suspended, and the push rod on the other side descends to the rear end face of the slab. The frame runs in the same direction as the slab under the drive of the traveling hydraulic cylinder. The push rod and roller linked to the frame drive the slab together to overcome the resistance of the scraper to remove burrs. After the deburring work is completed, the scraper of the deburring machine descends, and the movable body rises to its original position driven by the lifting hydraulic cylinder, waiting for the next short fixed-length slab.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The push-type deburring booster is suitable for a wide range of slab specifications, ensuring that the slab overcomes the resistance of the scraper during deburring, improving the deburring rate, ensuring the safe and stable operation of the deburring machine, and improving the deburring effect of the slab.
