Problems solved by technology

[0004] 1. The use of large machine tools or special machine tools is costly;
[0005] 2. The long (8m or 12m) channel steel itself has great flexibility, and there are many clamping points for fixture positioning points, resulting in complex fixture structure and long installation and adjustment time
[0006] 3. The long-grown (8m or 12m) channel steel itself has a large amount of deformation and complex deformation forms. Once installed and clamped, repeated adjustments and inspections are required, but the deformation cannot be eliminated, resulting in low processing efficiency and out-of-tolerance processing dimensions

Embodiment 1

[0035] The ultra-long profile processing device provided in this embodiment includes a milling machine and two supports. The workbench of the milling machine is adjustable in height and can be fed along the length direction of the workpiece; two clamps for positioning the workpiece are fixed in parallel on the workbench. There are rollers on the top of the bracket, which can reduce the friction when the workpiece moves; two brackets are set on both sides of the worktable, and keep a certain distance from the worktable, and the bracket and the fixture are on the same line.

[0036] Working principle of this embodiment: the processing method of the above-mentioned ultra-long profile processing device includes the following steps: the channel steel is fixed on the workbench by the clamp, and the protruding parts of the two ends of the workpiece are supported by the bracket. At this time, the height of the top of the bracket and the workbench Same, record the height of the worktabl...

Embodiment 3

[0046] This embodiment provides a method for processing super-long profiles, which is used to process welding notches of super-long channel steel, which specifically includes the following steps:

[0047] A. Install the two fixtures in parallel on the workbench of the vertical milling machine;

[0048] B. Place the brackets on both sides of the workbench of the vertical milling machine. The processed channel steel is placed on the brackets; the height of the brackets is adjusted roughly and finely to make the height of the channel steel consistent with the installation height of the fixture, and write down the workbench (original position value) height value;

[0049] C. Clamp the channel steel with a fixture to realize the horizontal and vertical positioning of the channel steel; start the milling machine, the milling machine table feeds and processes the notch, feeds to 100-150mm from the end of the stroke, and stops;

[0050] D. Loosen the fixture, lower the workbench, ret...

Abstract

The invention discloses an overlong sectional material machining device and method. The overlong sectional material machining device comprises a milling machine and a bracket, wherein the height of a working platform of the milling machine is adjustable and the working platform can be fed along the length direction of a workpiece; a plurality of clamps used for positioning the workpiece are fixedon the working platform in parallel; a roller is arranged at the top end of the bracket; and the bracket is arranged on the two sides of the working platform, and the bracket and the clamps are arranged on the same straight line and used for supporting the workpiece which is machined. The overlong sectional material machining device has a simple and reasonable structure, overcomes the defects of the prior art, realizes the advantages of low cost, high machining efficiency and high machining precision, and can be widely applied to machining of various overlong sectional materials. The invention also provides an overlong sectional material subsection milling method.

Description

technical field [0001] The invention relates to profile processing technology, in particular to an ultra-long profile processing device and processing method. Background technique [0002] The processing of super-long profiles has always been a difficult problem for manufacturers. For example, the side beams of the general-purpose bus chassis are super-long profiles, which are generally 8-meter or 12-meter-long channel steel. 3mmx14mm welding notch. Due to the deformation and flexibility of the channel steel profile, it is very difficult to adjust the positioning during full-length processing, and it is difficult to guarantee the accuracy requirement of the depth dimension of 3mm. [0003] Existing processing technology all adopts the gantry type, single-arm type, bed type milling machine planer or special lathe with processing length greater than the channel steel length, once installed and processed. However, these ultra-long profile processing methods all have the follo...
