Description

Technical Field

[0001] The utility model relates to the technical field of H-beam flange straightening machines, in particular to an overheating-proof H-beam flange straightening machine. Background Art

[0002] H-shaped steel is an economical and efficient profile with a more optimized cross-sectional area distribution and a more reasonable strength-to-weight ratio. It is named because its cross-section is the same as the English letter "H". During the welding process of H-shaped steel, the flange plate will inevitably bend and deform due to the concentrated heat input at the weld. The H-shaped steel flange straightening machine is a special equipment used to straighten the flange plate of welded H-shaped steel.

[0003] When the common straightening machines on the market are in use, the transmission roller relies on friction to drive the H-beam to move, and the correction is performed while moving. After long-term use, a large amount of heat is generated on the surface of the transmission roller. If the heat is not dissipated in time, the flange of the H-beam will soften, affecting the correction result. Therefore, an anti-overheating H-beam flange straightening machine is proposed to address the above problems. Utility Model Content

[0004] The utility model aims to provide an overheat-proof H-beam flange straightening machine to solve the problem that the correction result will be affected if the heat at the driving roller is not dissipated in time.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] The cam is provided with a plurality of holes on one side of the cam, and the plurality of holes are provided on the cam, and the plurality of holes are provided on the cam.

[0007] Preferably, a handle having a spherical end is fixedly connected to the top of the rubber stopper, and the top of the handle is located lower than the highest point of the transmission roller.

[0008] Preferably, one end of the copper rod passes through the outer wall of the driving roller and the fixed frame, and the cross-sectional area of ​​the copper plate and the driving roller is consistent.

[0009] Preferably, a pulling member with a T-shaped cross section is slidably connected to one side of the support plate, a limiting block for penetrating the hole of the positioning column is fixedly connected to one end of the pulling member, and a spring is provided on the outside of the pulling member.

[0010] Preferably, the spring is arranged between the limiting block and the inner wall of the groove opened in the support plate, and the positioning column and the limiting block are both arranged in the groove opened in the support plate.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] In the utility model, through the machine body, fixed plate, transmission roller, fixed frame, through hole and rubber plug, the user can pull out the rubber plug, fill the fixed frame in the transmission roller with coolant, and effectively cool down the overall temperature of the transmission roller; through the handle arranged on the top of the rubber plug, it is convenient to pull out and insert the rubber plug; through the copper plate and copper rod, since the copper material has good heat conductivity, the heat on one side of the transmission roller can be transferred to the coolant through the copper rod for heat dissipation and cooling, which further increases the heat dissipation effect of the transmission roller; through the support plate, hollow frame, motor and heat dissipation fan, the user starts the motor to drive the heat dissipation fan to rotate, which can effectively dissipate the heat at the transmission roller and the remaining rotating rollers, so that the H-shaped steel has a heat dissipation effect during the correction process; through the positioning column, pulling member, limit block, spring and groove, the user can pull the pulling member to fix the positioning column under the hollow frame, thereby fixing the hollow frame 11; the detachable hollow frame 11 is convenient for cleaning and maintenance.

A hollow frame 11 is tightly fitted on the top of the support plate 10. A cooling fan 13 is arranged in the hollow frame 11. One end of the cooling fan 13 passes through the hollow frame 11 and is fixedly connected to the output shaft of the motor 12. A positioning column 14 with a hole in the middle is fixedly connected to the bottom of the hollow frame 11. A groove 18 is opened in the support plate 10.

[0025] A handle 7 with a spherical end is fixedly connected to the top of the rubber plug 6. The position of the top of the handle 7 is lower than the highest point of the transmission roller 3, which is convenient for pulling out and inserting the rubber plug 6, and does not affect the fitting transmission of the transmission roller 3 and the H-shaped steel; one end of the copper rod 9 passes through the outer wall of the transmission roller 3 and the fixed frame 4, and the cross-sectional area of ​​the copper plate 8 and the transmission roller 3 is consistent, so that the copper plate 8 and the copper rod 9 can transfer the heat at the transmission roller 3 to the coolant for cooling and heat dissipation; a pulling member 15 with a T-shaped cross-section is slidably connected to one side of the support plate 10, and a limit block 16 for passing through the hole of the positioning column 14 is fixedly connected to one end of the pulling member 15, and a spring 17 is provided on the outside of the pulling member 15 for fixing the positioning column 14; the spring 17 is arranged between the limit block 16 and the inner wall of the groove 18 opened in the support plate 10, and the positioning column 14 and the limit block 16 are both arranged in the groove 18 opened in the support plate 10, which is convenient for disassembly of the hollow frame 11.

[0026] Working process: During the operation of the equipment, the external power supply is energized. When the overheat-proof H-beam flange straightening machine is in use, first place the machine body 1 in a suitable position, and the user holds the handle 7 and moves it upward, driving the rubber plug 6 to move upward at the same time until it is pulled out, and then pours coolant into the through hole 5 opened on the outer wall of the transmission roller 3 and the fixed frame 4, and then inserts the rubber plug 6 into the through hole 5, passes the H-beam through the two fixed plates 2, and the transmission roller 3 is attached to the H-beam to convey and correct it.

By setting up several structures with heat dissipation and cooling, the heat generated by the H-shaped steel during the correction process can be effectively cooled and dissipated, thereby avoiding the situation where heat affects the correction result.
