Technical Field

[0001] The utility model relates to the technical field of straightening machines, in particular to a roller surface protection and cooling water pipe strengthening structure of a hot straightening machine. Background Art

[0002] The hot straightening machine for steel plates is a mechanical device used to correct the shape defects of steel plates produced during the hot rolling process. This equipment is usually used after hot rolling of steel to ensure that the straightness of the steel meets the product requirements. The hot straightening machine can work in different temperature ranges. Generally, hot straightening is carried out at 650-1000℃ and is mainly used for the production of medium and thick plates. The straightening temperature is an important parameter in the hot straightening process. If the straightening temperature is too high, the steel plate may bend during the cooling process. If the straightening temperature is too low, the straightening resistance will increase, making straightening difficult.

[0003] When the hot straightening machine is working, the temperature of the steel plate is usually between 600℃ and 850℃, which means that when the straightening roller contacts the high-temperature steel plate, the roller surface temperature will also rise, possibly reaching 300℃ to 400℃. In order to control the temperature of the straightening roller and avoid damage caused by overheating, the working roller of the hot straightening machine is usually cooled by cooling water pipes so that the straightening roller is kept between 100℃ and 200℃. At present, the cooling water pipes of the straightening machine will deform due to high temperature during use, and then contact with the straightening roller to cause wear of the roller surface, and scratches will be generated, making the surface of the steel plate rough. For this reason, a hot straightening machine roller surface protection and cooling water pipe strengthening structure is proposed. Utility Model Content

[0031] like Figures 1 to 6 As shown, a roller surface protection and cooling water pipe strengthening structure of a hot straightening machine comprises: a fixed seat 1, a support frame 101 is arranged outside the fixed seat 1, there are multiple support frames 101, straightening rollers 102 are arranged between the support frames 101, there are multiple straightening rollers 102, and the straightening rollers 102 are distributed in two rows; a connecting member 2 is arranged outside the fixed seat 1, and is used to guide cooling water; a cooling pipe 3 is arranged inside the support frame 101, and is used to cool the straightening roller 102; a supporting member 4 is arranged inside the cooling pipe 3, and is used to increase the strength of the cooling pipe 3. Specifically, in the process of straightening treatment, the cooling water flow is first guided by the connecting member 2, so that the water flow can evenly enter the cooling pipe 3. In the process of cooling the straightening roller 102, the cooling pipe 3 is supported by the supporting member 4, so as to increase the strength of the cooling pipe 3 when in use, avoid the bending of the cooling pipe 3 due to heat during use, and then the bent cooling pipe 3 contacts the straightening roller 102 to cause the surface of the straightening roller 102 to be damaged, thereby ensuring stability during use.

[0032] like Figures 1 to 6As shown, the connecting member 2 includes a connecting pipe 201, which is connected to the fixing seat 1. A water inlet pipe 202 is provided on the outside of the connecting pipe 201, and the water inlet pipe 202 is communicated with the connecting pipe 201.

Specifically, the inside of the connecting pipe 201 is hollow, and the control valve 203 can control the cooling water flow to ensure the cooling effect of the straightening roller 102 when in use. When in use, the cooling water first enters the connecting pipe 201 through the water inlet pipe 202, so that the cooling water is temporarily stored in the connecting pipe 201, and then the temporarily stored cooling water enters the cooling pipe 3 evenly through the adjustment of the control valve 203, so as to avoid the cooling efficiency being reduced due to the uneven water flow in the cooling pipe 3 when in use.

[0033] like Figures 1 to 6 As shown, the cooling pipe 3 is open at one end, there are multiple cooling pipes 3, and the cooling pipes 3 correspond to the control valve 203. The multiple cooling pipes 3 are staggered with the top straightening roller 102. The open end of the cooling pipe 3 is provided with a connecting pipe 302, and the connecting pipe 302 is connected to the control valve 203. The outer side of the cooling pipe 3 is provided with a water outlet hole 301. There are multiple water outlet holes 301, and the water outlet holes 301 are distributed in multiple rows. The open end of the cooling pipe 3 is also provided with a limiting component 5 for fixing the support member 4. Specifically, the cooling pipe 3 is made of stainless steel, and the water outlet holes 301 distributed in multiple rows can guide the cooling water to evenly cool the straightening roller 102, avoid uneven cooling during use, and ensure the straightening effect.

[0034] like Figures 1 to 6 As shown, the support member 4 is arranged inside the cooling tube 3, and a guide hole 402 is provided inside the support member 4, and the guide hole 402 penetrates the support member 4, and the extension direction of the guide hole 402 is parallel to the axis of the support member 4, and a through groove 401 and a groove 403 are respectively provided on the outer side of the support member 4, and there are multiple through grooves 401, which are connected with the guide hole 402, and the opening direction of the through groove 401 is perpendicular to the axis of the support member 4.

The support member 4 is made of carbon steel. During use, the support member 4 provides support to the cooling tube 3 to avoid local deformation of the cooling tube 3 due to heat during use. The guide hole 402 cooperates with the through groove 401 and the groove 403 to guide the coolant, so that the coolant inside the guide hole 402 can be discharged through the water outlet 301, thereby ensuring stability during cooling.

[0035] like Figures 1 to 6As shown, the limiting assembly 5 includes a block 501 and a fixing member 6, the block 501 is arranged inside the cooling pipe 3, and the block 501 is abutted against the end of the support member 4, a through hole 502 and an annular groove 504 are arranged inside the block 501, the through hole 502 penetrates the block 501, the annular groove 504 penetrates one end of the block 501, the fixing member 6 is arranged inside the annular groove 504, a connecting rod 505 is movably connected inside the block 501, and there are multiple connecting rods 505, a receiving groove 503 is arranged on the outside of the block 501, the receiving groove 503 corresponds to the connecting rod 505, a contact member 506 is arranged inside the receiving groove 503, and the contact member 506 moves relative to the block 501, and the contact member 506 is connected to the connecting rod 505, specifically, the contact member 506 is made of high temperature resistant rubber material The quality of the block 501 is increased, thereby increasing the stability of the position of the block 501 relative to the cooling tube 3 during use. The storage groove 503 guides the contact piece 506 to ensure the accuracy of the direction of the contact piece 506 when it moves. At the same time, when the block 501 is removed, the contact piece 506 is stored to avoid the contact piece 506 from contacting the inner wall of the cooling tube 3 and causing difficulty in removal. When the support piece 4 is placed in the cooling tube 3, the block 501 is first abutted against the support piece 4. After the abutment is completed, the connecting rod 505 is pushed outward by the fixing piece 6. When the connecting rod 505 is extended, the contact piece 506 is driven to fit with the inner wall of the cooling tube 3, so that the block 501 fixes the position of the support piece 4, avoids the support piece 4 from moving relative to the cooling tube 3 during use, and ensures stability during use.

[0036] like Figures 1 to 6 As shown, the fixing member 6 includes a limiting tube 602, which is conical relative to the end of the blocking block 501, and a connecting block 601 is provided at the other end of the limiting tube 602. Specifically, the limiting tube 602 is connected to the annular groove 504 by a thread, and the connecting block 601 can be connected to a socket wrench, so that the limiting tube 602 can be controlled. When in use, since one end of the limiting tube 602 is conical, during the movement of the limiting tube 602, the limiting tube 602 cooperates with the connecting rod 505 to push the contact member 506 to expand and contract, which is convenient for disassembly and installation of the support member 4.
