Abstract

The invention discloses a method for making cold rolled section steel, and relates to the technical field of a metal cold roll forming method. The method comprises the following steps: (1) putting corresponding dies of products needing to be produced onto a cold rolled section unit roll shaft, adjusting the horizontal line of a bottom die, loading a material into a feeding frame, and introducing into a rolling forming unit; (2) introducing into a first orienting die through a seven-roll leveling device, rolling by an angle of 15 degrees through a flat plate material, treating through a plurality of dies having the angles of 20 degrees, 25 degrees, 30 degrees, 35 degrees, 40 degrees, 45 degrees, 50 degrees, 60 degrees and 90 degrees, adjusting each die to a required angle, and adjusting the pressure of each die within the same index; (3) inspecting, pasting labels, packaging and warehousing. In the method, a roll forming process is adopted. The method has the advantages of simple structure, convenience in operation, higher economic benefit, high yield, capability of saving time, labor and energy, safety, environmental friendliness and wide application range.

Description

A kind of preparation method of cold-rolled forming section

Technical field

The present invention relates to metal cold roll forming preparation method technical field, relate in particular to a kind of preparation method of cold-rolled forming section.

Background technology

Traditional metal crimping process using Sheet Metal Forming Technology, its complex structure, inconvenient operation, business efficiency is low, and output is not high, inadequate safety and environmental protection, labour is not strong, relatively wastes time and energy, and range of application is extensive not.

Summary of the invention

The preparation method that the object of this invention is to provide a kind of cold-rolled forming section, it adopts rolling-type moulding process, simple in structure, easy to operate, has higher economic benefit, and output is high, time saving and energy saving, energy-saving, safe and environment-friendly, range of application is more extensive.

In order to solve the existing problem of background technology, the present invention is by the following technical solutions: its preparation method is: 1, the corresponding mould of the product of required production is packed on cold-forming shapes unit roll shaft, the horizontal line of adjusting bed die, packs stock shelf into material, introduces roll forming unit; 2, through seven roller leveling apparatus, enter the directed mould of first, by plate material, be rolled into 15 ° of angles, so again through the mould of 20 °, 25 °, 30 °, 35 °, 40 °, 45 °, 50 °, 60 °, 90 ° multiple tracks different angles, angle per pass die adjustment to necessary requirement, make per pass die adjustment pressure all in identical index, according to section configuration, determine; 3, progressively will make required shape of product with steel roll extrusion, then turn round alignment by tune, after fixed scale frame, by the wrong cutter of hydraulic press, cut off, according to the length of customer requirement, operate; 4, check, labeling, packing and warehouse-in.

The present invention adopts rolling-type moulding process, simple in structure, easy to operate, has higher economic benefit, and output is high, time saving and energy saving, energy-saving, safe and environment-friendly, and range of application is more extensive.

The specific embodiment:

This specific embodiment is by the following technical solutions: its preparation method is: 1, the corresponding mould of the product of required production is packed on cold-forming shapes unit roll shaft, adjust the horizontal line of bed die, material is packed into stock shelf, introduce roll forming unit; 2, through seven roller leveling apparatus, enter the directed mould of first, by plate material, be rolled into 15 ° of angles, so again through the mould of 20 °, 25 °, 30 °, 35 °, 40 °, 45 °, 50 °, 60 °, 90 ° multiple tracks different angles, angle per pass die adjustment to necessary requirement, make per pass die adjustment pressure all in identical index, according to section configuration, determine; 3, progressively will make required shape of product with steel roll extrusion, then turn round alignment by tune, after fixed scale frame, by the wrong cutter of hydraulic press, cut off, according to the length of customer requirement, operate; 4, check, labeling, packing and warehouse-in.

This specific embodiment adopts rolling-type moulding process, simple in structure, easy to operate, has higher economic benefit, and output is high, time saving and energy saving, energy-saving, safe and environment-friendly, and range of application is more extensive.
