Embodiment 1

[0036] see Figure 1 to Figure 8, is an energy-saving pendulum shear for thin slab continuous casting and rolling, including a motor 1, a gear box 2, an eccentric crankshaft 3, a negative pressure system 7, an upper shearing device 8, a swing frame 9, a lower shearing device 10, and a motor 1 The gear box 2 is connected with the eccentric crankshaft 3, the eccentric crankshaft 3 is connected with the upper shearing device 8, the eccentric crankshaft 3 is installed on the swing frame 9, the motor 1 drives the eccentric crankshaft 3 to rotate, drives the upper shearing device 8 to move, and the lower shearing device 8 The cutting device 10 jointly realizes the shearing of the slab. Among them, a guide sleeve 4 and a guide rod 5 are installed between the upper shearing device 8 and the eccentric crankshaft 3; one end of the guide sleeve 4 is rotated and installed on the eccentric crankshaft 3 through a split bearing 11, and the other end is provided with a guide hole 42; the guid...

Embodiment 2

[0041] The difference between this embodiment and embodiment 1 is that the number of wedge-shaped block 6 is only one, the driving device adopts a single-cylinder hydraulic cylinder, and other structures and connections are the same as in embodiment 1.

Abstract

The invention belongs to the technical field of continuous casting and rolling, and relates to an energy-saving thin slab continuous casting and rolling pendulum shear. A guide sleeve and a guide rod are arranged between an upper shearing device of the pendulum shear and an eccentric crankshaft; one end of the guide sleeve is rotatably connected with the eccentric crankshaft, the other end of the guide sleeve is provided with a guide hole, one end of the guide rod is slidably connected with the guide sleeve through the guide hole, and the other end of the guide rod is connected with the upper shearing device; a first positioning surface is arranged on the guide sleeve, and a second positioning surface is arranged on the guide rod; a wedge block is arranged between the first positioning surface and the second positioning surface; the first positioning surface and the second positioning surface are in surface contact with the wedge-shaped block; the wedge-shaped block is connected with a driving device; and the wedge-shaped block is driven by the driving device to slide between the first positioning surface and the second positioning surface so as to adjust the distance between the first positioning surface and the second positioning surface. By means of the energy-saving thin slab continuous casting and rolling pendulum shear, the wedge-shaped block is adopted to replace a traditional hydraulic cylinder positioning manner, and a hydraulic pressurization system is omitted, so that the requirements of a power system and an oil supply system of a hydraulic station are reduced, and the equipment investment cost and energy consumption of the pendulum shear are reduced.

Description

technical field [0001] The invention belongs to the technical field of continuous casting and rolling, and relates to an energy-saving pendulum shear for continuous casting and rolling of thin slabs. Background technique [0002] The pendulum shear is an important core equipment in the thin slab continuous casting and rolling mill, which is used for shearing the dummy bar and the intermediate billet. Since the slab to be sheared has a large thickness and a large width, the required shearing force is also very large. [0003] In the prior art, such as the Chinese patent with the publication number CN112809066A, a hot-rolled slab connecting device is disclosed, which includes an upper shearing device and a lower shearing device, a fixed frame, a hydraulic shearing device and the Hot-rolled slab pendulum shear swing control device. The hot-rolled slab pendulum shear swing control device includes the assembly of the transmission eccentric crankshaft and the assembly of the swi...
