When the rust removal roller 508 rotates, the eccentric block 512 is driven to rotate synchronously, thereby squeezing the second abutment plate 516, driving the second piston 514 to reciprocate in the second cylinder 513, so that the third one-way valve 518 and the fourth one-way valve 519 are alternately turned on, and air is injected into the dust removal pipe 520 and sprayed from the second spray hole 521 to the surface of the profile, so as to further spray dust on the profile and ensure the bending quality.

[0050] A bending method for steel profile processing, applicable to the above-mentioned bending equipment for steel profile processing, comprises the following steps:

[0051] S1: feeding; the profile is inserted between the abutting roller 504 and the driving roller 502, and the driving roller 502 is driven to rotate by the second motor 503 to convey the profile forward. At the same time, the two rust removal rollers 508 are driven to rotate, and the surface of the profile is rusted and cleaned by the wire brush 509. When the rust removal roller 508 rotates, the eccentric block 512 is driven to rotate synchronously to squeeze the second abutting plate 516, inject air into the dust removal pipe 520, and spray it from the second spray hole 521 to the surface of the profile, so as to further spray dust on the profile;

[0052] S2: Bending; after the profile to be bent is fed between the bending roller 302 and the moving roller 309, the sleeve 307 can be driven to rotate clockwise by the electric telescopic rod 313, and the profile is covered on the surface of the bending part 303 by the moving roller 309 to be bent. At the same time, the push rod 314 moves synchronously, thereby driving the first abutment plate 319 to move toward the first cylinder 315, and injecting air into the heating chamber 304 through the cavity 322. After being heated by the heating coil 305, the air is sprayed from the first spray hole 306 to the bending part of the profile to evenly heat the profile;

[0053] S3: unloading; the first motor 403 drives the half gear 402 to rotate one circle clockwise, thereby driving the second gear 401 to drive the bending roller 302 to rotate half a circle counterclockwise, so that the bending part 303 is separated from the surface of the profile, and at the same time, drives the limit frame 310 to move away from the profile direction, cancels the limit on the profile, and when the second gear 401 rotates, drives the second tooth plate 410 to move, thereby driving the driving block 408 and the cutter 409 on one side to move, and drives the cutter 409 on the other side to move closer through the third tooth plate 411 and the fifth gear 412 to cut the profile, and the bent profile can be taken out.

[0054] Specifically, the working principle of the bending equipment for processing steel profiles is as follows: when in use, the profile is inserted between the clamping roller 504 and the driving roller 502, and the driving roller 502 is driven to rotate by the second motor 503 to transport the profile forward. At the same time, the two rust removal rollers 508 are driven to rotate by the sixth gear 510 and the seventh gear 511, and the surface of the profile is rusted and cleaned by the wire brush 509 to ensure the flatness of the profile surface. When the rust removal roller 508 rotates, the eccentric block 512 is driven to rotate synchronously, thereby squeezing the second abutment plate 516, driving the second piston 514 to reciprocate in the second cylinder 513, so that the third one-way valve 518 and the fourth one-way valve 519 are alternately turned on, and air is injected into the dust removal pipe 520, and sprayed from the second spray hole 521 to the surface of the profile, so as to further spray dust on the profile and ensure the bending quality.

[0055] The profile to be bent is fed between the bending roller 302 and the moving roller 309. The electric telescopic rod 313 is extended to drive the first gear 311 through the first tooth plate 312 to drive the sleeve 307 to rotate clockwise, and the profile is covered on the surface of the bending part 303 through the moving roller 309 to be bent. At the same time, the bracket 308 drives the push rod 314 to move synchronously, thereby driving the first abutment plate 319 to move toward the first cylinder 315, and injecting air into the heating chamber 304 through the cavity 322 through the first piston 316. After being heated by the heating coil 305, the air is sprayed toward the bending part of the profile from the first spray hole 306 to evenly heat the profile. By heating the bending part, the plasticity of the material can be improved, so that more deformation becomes irreversible plastic deformation, the elastic deformation part is reduced, and the residual stress inside the profile is released and reduced, thereby reducing the rebound force of the profile after bending.

[0056] After the bending is completed, the first motor 403 drives the half gear 402 to rotate one circle clockwise, thereby driving the second gear 401 to drive the bending roller 302 to rotate half a circle counterclockwise, so that the bending part 303 is separated from the surface of the profile. At the same time, the half gear 402 drives the fourth gear 407 to rotate synchronously, drives the third gear 406 and the first screw rod 404 to rotate, drives the first threaded block 405 to drive the limiting frame 310 to move away from the profile, and cancels the limit on the profile. When the second gear 401 rotates, it drives the second tooth plate 410 to move, thereby driving the driving block 408 and the cutter 409 on one side to move, and drives the cutter 409 on the other side to move closer through the third tooth plate 411 and the fifth gear 412 to cut the profile, so that the bent profile can be taken out for easy use.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
