Description

Technical Field

[0001] The utility model belongs to the field of deburring equipment for continuous casting machines, in particular to a high-efficiency deburring machine. Background Art

[0002] During continuous casting production, a flame cutting machine is usually used to cut the steel billet into fixed lengths. During this process, a certain amount of burrs will be generated at the head and tail of the steel billet, which need to be removed by a deburring machine, otherwise it will affect the quality and production efficiency of rolling. There are many types of deburring machines, among which the widely used serrated deburring machine has the function of cutting burrs longitudinally and transversely at the same time. For example, patent publication number CN 204545600 U discloses a continuous casting billet deburring machine with a combined serrated scraper. The crossbeam box is a U-shaped structure, the knife seat is arranged in the movable body, the movable body is arranged in the crossbeam box, and the driving device causes the movable body to produce transverse reciprocating motion through a connecting rod. The temperature of the steel billet when passing through the deburring machine is 800±50℃. This type of crossbeam box structure is prone to deformation and bending under high temperature baking and impact, and the movable body will also deform accordingly, resulting in poor contact between the knife head and the steel billet, affecting the deburring effect. Patent publication number CN 112658225 A discloses a toothed deburring machine for the upper and lower surfaces of a continuous casting stainless steel slab. Its crossbeam is also a U-shaped structure, with holes opened on the side for the transverse connecting rod to pass through; the knife row is arranged on the lower crossbeam, and the knife row driving mechanism is arranged at the end of the lower crossbeam. The knife row can move relative to the crossbeam, and there is a moving space for the knife row inside the crossbeam. It can be seen that the crossbeam is also a box structure, and there is also the problem of easy deformation under high temperature baking and impact, which affects the deburring effect.

DETAILED DESCRIPTION

[0027] The present invention is described in detail below in conjunction with the accompanying drawings of the specification, but it should be noted that the implementation of the present invention is not limited to the following embodiments.

[0028] See Figure 1-Figure 9 A high-efficiency deburring machine includes a support beam 1, a bearing 2, a bearing box 3, a guide frame, and a cutter head assembly 10. The support beam 1 is supported on the bearing box 3 through the bearing 2, and the bearing 2 is interference fit with the support beam 1. The support beam 1 is a closed structure, and a mounting hole 102 is opened on the top of the support beam 1 for connecting with the cutter head assembly 10; the bearing box 3 is slidably connected to the guide frame through a roller 304.

[0029] The cutter head assembly 10 is clearance-matched with the mounting holes 102. The number of mounting holes 102 is 15 to 30, and the number of cutter head assemblies 10 is the same as the number of mounting holes 102. The cutter head 11 is fixedly connected to the cutter head assembly 10 by bolts. The top of the support beam 1 is a convex structure, and the mounting holes 102 are opened at the convex structure.

[0030] The support beam 1 is a solid structure with an integrated structure, the middle section is a square with a raised top, and the sections at both ends are circular. A water cooling channel 101 is provided in the support beam 1, and the water cooling channel 101 is arranged on both sides of the mounting hole 102. The water cooling channel 101 is connected at the end of the support beam 1 through a connecting channel 103. The cross section of the water cooling channel 101 is rectangular to increase the cooling area. Once the steel billet stays at the deburring machine for a long time, cooling water can be passed to the water cooling channel 101 on one side of the mounting hole 102. The cooling water enters from one end of the water cooling channel 101, passes through the connecting channel 103 from the other end, and enters the water cooling channel 101 on the other side of the mounting hole 102, and then flows out from the end of the water cooling channel 101 on the other side of the mounting hole 102, completing the cooling of the support beam 1, and preventing the support beam 1 from being deformed due to being in a high temperature environment for a long time.

[0031] The bearing box 3 is connected to rollers 304 on both sides and the upper and lower ends. There are eight rollers 304, which are connected to the guide frame through the rollers 304. The bearing box 3 includes a box body 301, a transparent cover 302, and a sealing ring 303. The bearing 2 is installed in the box body 301. The transparent cover 302 is connected to one side of the box body 301. The sealing ring 303 is connected to the transparent cover 302 and the other side of the box body 301. After the bearing 2 is installed in the box body 301, the transparent cover 302 is installed to seal the bearing 2 in the box body 301.

[0032] The guide frame is a square frame structure, and the square hole 501 in the guide frame rolls with the roller 304. The guide frame is composed of two guide frames, namely guide frame 1 5 and guide frame 2 6, which are respectively connected to two bearing boxes 3. The guide frame is fixedly connected to the equipment foundation through a support.

[0033] See Figure 1-Figure 3 One end of the support beam 1 (close to the guide frame 2 6) is hinged to the transverse connecting rod 7, and the other end (close to the guide frame 1 5) is connected to the flip gear 4. The flip gear 4 can be driven by the driving device to rotate 90°, and the flip gear 4 then drives the support beam to rotate 90°, and the cutter head 11 also flips 90°, and the residual burrs, slag, etc. on the support beam 1 and the cutter head 11 are poured away.

[0034] The other end of the lateral movement link 7 is hinged to the lateral movement eccentric sleeve 8. The guide frame 26 is connected to the lateral movement motor by bolts, and the lateral movement motor is connected to the lateral movement eccentric sleeve 8 by splines. The lateral movement motor seat 9 is fixed on the guide frame 6, and the lateral movement motor is fixedly connected to the lateral movement motor seat 9. The lateral movement motor drives the lateral movement eccentric sleeve 8 to rotate. Since the lateral movement eccentric sleeve 8 and the lateral movement link 7 are eccentrically installed, the lateral movement link 7 is guided by the roller 304 to achieve lateral movement.

[0035] The utility model has a reasonable structure. The support beam 1 adopts a closed structure instead of a box structure, which improves the rigidity. The cutter head assembly 10 is installed in the mounting hole 102 on the support beam 1, and no relative lateral movement occurs. When the cutter head 11 performs a deburring operation, reliable contact with the steel billet is ensured, and the contact area and contact pressure can also remain unchanged, and the burr removal rate is steadily improved. A water cooling channel 101 is set in the support beam 1, and cooling water can be passed through it to cool the support beam 1. The bearing box 3 and the guide frame are connected in a sliding manner, and the support beam 1 can move back and forth laterally with the bearing box 3.
