Description

Technical Field

[0001] This utility model belongs to the field of steelmaking continuous casting, specifically relating to a movable cutter holder guide slide mechanism and a hydraulic shearing machine for continuous casting billets. Background Technology

[0002] The hydraulic shearing machine for continuous casting billets is a type of equipment used for cutting billets to length in continuous casting machines. It is characterized by enormous shearing forces (thousands of tons), high-temperature operating environments, large billet cross-sections, and the need for frequent blade changes to adapt to different cross-sections. Its performance directly impacts the normal production of the continuous casting machine, making it a crucial piece of equipment in continuous casting production. To ensure continuous and stable operation of the hydraulic shearing machine, it needs to be equipped with a movable blade holder guide slide mechanism and a blade side clearance adjustment wedge slide mechanism. The movable blade holder guide slide mechanism limits the movement of the movable blade holder (with the blades mounted) on both sides, providing an extremely stable and highly rigid linear motion track. The blade side clearance adjustment wedge slide mechanism allows for online, precise, and quantifiable adjustment of the lateral clearance between the upper and lower blades.

[0003] Currently, the guide slide of the movable cutter holder is mainly designed as a whole. The guiding accuracy depends on the manufacturing precision. It is very difficult to adjust the guide clearance during assembly, and there is even no function to adjust the guide clearance. The guide clearance increases with use, resulting in poor guiding effect during the shearing motion of the movable cutter holder, large side clearance between the upper and lower shear blades, and the movable cutter holder can only be replaced when the shearing clearance exceeds the tolerance. In addition, the guide slide is in a high-temperature working environment, and the high temperature accelerates the wear rate. The replacement and installation frequency is high. The installation design of the guide slide is unreasonable, and the replacement and installation are very troublesome, which increases the maintenance difficulty. Utility Model Content

[0004] The purpose of this utility model is to provide a movable tool holder guide slide mechanism and a continuous casting billet hydraulic shearing machine including the above mechanism, which is convenient to load and unload, easy to adjust the guide gap, and the wear-resistant slide can be replaced separately, saving spare parts costs.

[0005] The technical solution adopted in this utility model is: A movable tool holder guide slide mechanism includes a slide body and a wear-resistant slide. The slide body adopts an embedded installation structure. The two sides of the slide body are installed on the outside of the frame through shims, and the middle is embedded in the frame. The shims are used to adjust the guide gap between the slide body and the movable tool holder. The wear-resistant slide is separately set from the slide body. The wear-resistant slide is detachably installed on the guide surface of the slide body and is used to make guide contact with the movable tool holder.

[0006] Preferably, the skateboard body is connected to the frame on both sides by multiple connecting screws.

[0007] Preferably, the connecting screws on both sides of the skateboard body are arranged in a single vertical row, and the side of the washer has openings corresponding to each connecting screw. The washer can be inserted from the side between the skateboard body and the frame and allow the connecting screw to be accommodated in the corresponding opening.

[0008] Preferably, the slide body has two guide surfaces, one guide surface corresponding to the side of the movable cutter head, and the other guide surface being directly opposite the blade side clearance adjustment wedge slide mechanism. The wear-resistant slides are respectively installed on the two guide surfaces of the slide body. The wear-resistant slides on the slide body and the blade side clearance adjustment wedge slide mechanism together form a guide groove that surrounds the three sides of the movable cutter head.

[0009] Preferably, the movable tool holder guide slide mechanism is arranged in pairs on both sides of the frame, and the frame is provided with two pairs of movable tool holder guide slide mechanisms vertically.

[0010] Preferably, a baffle is provided on the outside of the frame, which limits one side of the slide body.

[0011] Preferably, the wear-resistant skateboard and the skateboard body are positioned by pins and connected by countersunk screws.

[0012] Preferably, the wear-resistant skateboard is made of hard alloy steel and its surface has undergone heat treatment.

[0013] Preferably, the skateboard body is made of cast steel, forged steel, or steel plate.

[0014] A hydraulic shearing machine for continuous casting billets includes the aforementioned movable cutter holder guide slide mechanism.

[0015] The beneficial effects of this utility model are: The skateboard body can be embedded and installed from the outside of the frame, which not only facilitates installation and disassembly but also makes it easy to observe the wear condition of the guide. In addition to the convenient installation and disassembly of the skateboard body, the guide clearance can be adjusted by replacing the shims, which is convenient. The wear-resistant skateboard adopts a split and detachable structure. When the wear-resistant skateboard is severely worn, it can be replaced separately without replacing the skateboard body, thus saving spare parts costs. Attached Figure Description

In this embodiment, the slide plate body 3 can be embedded and installed from the outside of the frame 1, which not only facilitates installation and disassembly but also facilitates observation of guide wear. Based on the convenient installation and disassembly of the slide plate body 3, the guide clearance can be adjusted by replacing the shim 7, making guide clearance adjustment convenient. The wear-resistant slide plate 2 adopts a separate, detachable structure. When the wear-resistant slide plate 2 is severely worn, it can be replaced separately without replacing the slide plate body 3, saving spare parts costs.
