Abstract
Description
Technical Field
[0001] The utility model relates to a pneumatic steel head pushing device of a hydraulic shear of a slab rolling mill, belonging to the technical field of hydraulic shears of slab rolling mills in metallurgy. Background Art
[0002] In domestic and foreign steel mills, the hydraulic shears of the billet mill have always been one of the indispensable equipment in the production process. After the billet mill is rolled, the billet needs to be cut or trimmed by the hydraulic shears before it can enter the continuous rolling mill for secondary rolling. When the hydraulic shears are cutting the billet heads or tails, due to the high temperature of the billet, the cut steel heads are easy to stick to the shear blades of the hydraulic shears and cannot fall off. Therefore, an operator needs to be permanently equipped at the hydraulic shears to clean the cut steel heads, which is time-consuming and laborious.
[0003] The solution to this problem is to design an automatic steel head pushing device. After the hydraulic shears finish cutting, the cut steel head can be cleaned up through the control of the solenoid valve. Therefore, the problem of personnel manually cleaning the cut steel head has been solved. Utility Model Content
[0004] The utility model aims to provide a hydraulic shear pneumatic steel head pushing device, which can automatically clean up the cut head or cut tail adhered to the lower shear blade of the hydraulic shear, and solve the problems existing in the background technology.
[0005] The technical solution of the utility model is:
[0006] A pneumatic steel head pushing device for a hydraulic shear of a billet rolling mill comprises a cylinder, a swing arm, a hammer, a main frame of the hydraulic shear, a cylinder support and a swing arm support, wherein the cylinder body of the cylinder is hinged on the cylinder support, the cylinder rod of the cylinder is hinged to one end of the swing arm, the other end of the swing arm is provided with a hammer that matches the steel head adhered to the lower shear blade of the hydraulic shear, the middle of the swing arm is rotatably connected to the swing arm support, and the cylinder support and the swing arm support are respectively fixed on the main frame of the hydraulic shear.
[0007] The striker is fixed to the end of the swing arm.
[0008] The hammer is a rectangular parallelepiped.
[0009] One end of the swing arm hinged to the cylinder rod is provided with a proximity switch matched with the swing arm.
[0010] The proximity switch is fixed on the main frame of the hydraulic shear through a bracket.
[0011] The middle of the swing arm is rotatably connected to the swing arm support through a swing shaft.
[0012] The utility model utilizes the lever principle and controls the cylinder through the electromagnetic valve to drive one end of the swing arm to extend and retract, so that the hammer at the other end knocks the steel head out of the hydraulic shearing opening, thereby automatically cleaning the steel head stuck on the lower cutting blade of the hydraulic shearing.
[0013] The utility model has the beneficial effect that after the hydraulic shears cut the head or tail of the steel billet, the cut head or tail adhered to the shearing blade of the hydraulic shears can be automatically cleaned off. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0017] The present invention will be further described below by way of examples with reference to the accompanying drawings.
[0018] Refer to the attached Figure 1-2 A pneumatic steel head pushing device for a hydraulic shear of a billet rolling mill comprises a cylinder 5, a swing arm 6, a hammer 8, a main frame of the hydraulic shear 12, a cylinder support 13 and a swing arm support 14. The cylinder body of the cylinder 5 is hinged on the cylinder support 13, the cylinder rod of the cylinder 5 is hinged to one end of the swing arm 6, and the other end of the swing arm 6 is provided with a hammer 8 that matches the steel head adhered to the lower shear blade of the hydraulic shear. The middle of the swing arm 6 is rotatably connected to the swing arm support 14, and the cylinder support 13 and the swing arm support 14 are respectively fixed on the main frame 12 of the hydraulic shear.
[0019] In this embodiment, refer to the attached Figure 1-2 The gas supply valve 1, the gas main line 2, the gas triplex 3 and the electromagnetic reversing valve 4 are common components matching the cylinder 5, and the model of the cylinder 5 is 125*250-S.
