Embodiment Construction

[0018] The present invention will be further described below in conjunction with embodiment:

[0019] A beveling process for an angle steel tower, comprising the steps of:

[0020] 1) Beveling equipment

[0021] 1.1) When the material specification is within the bearing capacity of the beveling machine, the beveling machine should be preferred; when it exceeds the bearing capacity of the beveling machine, flame cutting equipment should be used;

[0022] 1.2) HP-30 bevel processing machine is suitable for bevel processing with workpiece tensile strength of 390-690N / mm2 (Q235 is 375-460N / mm2, Q345 is 470-630N / mm2); the groove angle that can be processed is 20-50o

[0023] (2) The minimum height of blunt edge can be 0, but preferably greater than or equal to 2mm;

[0024] (3) The maximum width of the groove surface varies according to the strength of the workpiece;

[0025] (4) The maximum workpiece thickness is 60mm;

[0026] 2) Ambient temperature of rolling shear: When ca...

Abstract

The invention discloses an angle-steel tower beveling technology. The technology comprises 1, arranging a beveling device, 2, setting a roll shearing ambient temperature, wherein when a carbon structural steel temperature is lower than -20 DEG C and a low alloy structural steel temperature is lower than -15 DEG C, a roll shearing process is not carried out, and 3, carrying out beveling through 3.1, well knowing equipment performances and an operation instruction through an operator, carrying out operation according to a recommend technical standard or parameters, seriously executing company device management related provisions and strictly following safe operation rules, 3.2, when beveling, limiting beveling width within the largest beveling surface width W, necessarily detecting an initial workpiece to determine if the size, deviation, burr and appearance are qualified, carrying out batch production after inspection passing and carrying out self-inspection in the process or after the process and 3.3, selecting cutters comprising three types of thick-, middle- and thin-tooth special-purpose cutters, wherein the thin-tooth special-purpose cutter can make beveling smooth. The technology has reasonable processes, a low manufacturing cost and reasonable and coordinating parameter matching and effectively improves product quality and production efficiency.

Description

technical field [0001] The invention relates to a beveling process of an angle steel tower. Background technique [0002] The existing angle steel tower beveling process has unreasonable process arrangement, numerous processes, unreasonable selection of process parameters, unreasonable collocation of process parameters, and high requirements for operator experience, resulting in high production costs and low product quality. , The yield rate is not high. Contents of the invention [0003] In view of the above-mentioned defects of the prior art, the technical problem to be solved by the present invention is to provide a beveling process of an angle steel tower with reasonable process and low manufacturing cost. [0004] To achieve the above object, the present invention provides [0005] A beveling process for an angle steel tower, comprising the steps of: [0006] 1) Beveling equipment [0007] 1.1) When the material specification is within the bearing capacity of the ...
