Stainless steel bend

Stainless steel bend is also a kind of stainless steel special-shaped tube, which mainly differentiates the shape of the tube after forming, such as u-shaped tube, j-shaped tube, s-shaped tube and 90-degree serpentine bend.

Stainless steel special-shaped pipe is the general term of steel pipe with other section shapes except circular pipe. Due to the relationship of material, stainless steel special-shaped pipe is generally more than 304 material, with strong hardness of 200 and 201 material, making it more difficult to shape.

Stainless steel special-shaped tube is widely used in various structural parts, tools and mechanical parts. Compared with the circular tube, the stainless steel special-shaped tube generally has a larger inertia moment and section modulus, and a larger bending and torsion resistance, which can greatly reduce the weight of the structure and save steel.

Stainless steel section tube is generally based on cross section, the overall shape to differentiate, generally can be divided into: oval shaped steel tube, triangular shaped steel tube, hexagonal shaped steel tube, the diamond shaped steel tube, stainless steel decorative pattern pipe, stainless steel, U steel, D type pipe, stainless steel pipe bending, s-shaped curved pipe, octagonal shaped steel tube, semicircle deformed steel circle, not equilateral hexagons five disc shaped steel tube, the plum flower form shaped steel tube, double convex shaped steel tube, double concave shaped steel tube, melon seeds shaped steel tube, the cone shaped steel tube, corrugated shape profiled steel tube, etc.

Stainless steel section tube, stainless steel square tube, stainless steel square tube, specifications: 12.7 * 12.7 mm - 400 * 400 mm, thickness 0.6 mm to 20 mm, stainless steel pipe is usually 6 * 1-630 * 28. Specifications have four points, six points, 1 inch, 1.2 inch, 1.5 inch, 2 inch, 2.5 inch, 3 inch, 4 inch, 5 inch, 6 ", 8 ", 102, 108, 127, 133, 139, 159, 168, 177, 194, 219, 273, 325, 377, 426, 530, 630, etc. Stainless steel special-shaped tube generally refers to square moment steel tube, triangular tube, hexagon tube, stainless steel figure tube, U tube, D tube, water bend and so on.

What should be paid attention to when choosing the cutting quantity of stainless steel bend?

The size of cutting amount has a great influence on production efficiency and machining quality. Therefore, after determining the geometric parameters of the cutter, it is necessary to select a reasonable cutting amount. The following factors should be taken into account when selecting cutting amount: firstly, the cutting amount should be selected according to the hardness of the stainless steel stamping elbow and various blank. Secondly, the cutting quantity should be selected according to the cutting material, welding quality and cutting tool grinding conditions. The third is to be based on the diameter of parts, machining allowance and lathe accuracy to choose cutting dosage.

The stainless steel elbow, especially the austenitic type stainless steel ramming elbow, has good plasticity. In the cutting process, the chip is difficult to break, which increases the friction between the chip and the cutter surface and increases the cutting force. At the same time, machining hardening will increase the hardness and strength of the cutting material, and also increase the cutting force.

Reasonable selection of tool material, tool geometry and cutting amount can improve the production efficiency and quality of stainless steel elbow cutting.
