Problems solved by technology

[0002] The door slides commonly used in the market are formed by forging billet, steel ingot or steel. The processing process is complicated, the forming size is unstable, and the arc surface often appears uneven. The slide rail has relatively high requirements on the arc surface of the slide rail; due to the particularity of forging processing, there are often more shape deformations at the end and initial sections of the profile, which causes a large part of the material to be wasted because it cannot be used; forging Processing often requires high-temperature processing, and oil stains and other sundries stick to the product at high temperatures. This kind of oil stains is often difficult to deal with. Cleaning processes such as phosphating, pickling, etc. are required before spraying, galvanizing or electrophoresis on the finished product processing surface On the one hand, the processing cost is high, on the other hand, the waste cleaning solution will cause serious environmental pollution and high waste water treatment cost

Embodiment 1

[0025] A kind of sliding rail processing method provided in this embodiment, such as figure 1 As shown, including step A. Select the steel plate with the required width and thickness, such as figure 1 As shown in step A-1;

[0026] Step B. Carry out rolling from the lower part of the center of the steel plate to form the base segment 2 with the two sides 1 protruding upwards, and the base segment 2 is provided with a first arc surface 3, such as figure 1 Rolling according to the steps shown in B-1, the formation of the first arc surface 3 can make the processing of the two sides 1 easier, so that when the two sides 1 are bent upwards, there is enough extension capacity in the middle, avoid as much as possible The reduction of intermediate strength ensures the strength of the product;

[0027] Step C. Roll the two sides 1 from the upper part of both sides, and the two sides 1 gradually extend upwards to form the second arc surface 4, such as figure 1 Rolling according to the...

Embodiment 2

[0033] In the method for processing slide rails provided in this embodiment, in order to improve the strength, in addition to the features described in Embodiment 1, Step E is followed by Step F. Rolling the two sides 1 from the upper part until the two sides The side 1 ends towards the base segment 2 .

[0034] Such as image 3 As shown, the product obtained according to the method of this embodiment has lower processing difficulty, higher strength of the hanging wheel mounting surface 6, and better bearing capacity.

Embodiment 3

[0036] In the slide rail processing method provided in this embodiment, in order to improve the strength, in addition to the features described in Embodiment 2, the step F. is followed by step G. Bending the base body section 2 toward the direction of the two sides 1 Or rolling to form the first U-shaped side 7, and the two sides 1 are bent or rolled in the opposite direction. In this embodiment, the bending or rolling forming angle in step G. is 90 degrees, and the appearance is more beautiful.

[0037] Such as Figure 4 As shown, the product obtained according to the method of this embodiment has higher overall strength, and the mounting surface 6 of the hanging wheel can have a certain distance from the installation reference plane 5 of the slide rail, so as to avoid interference between the installation of the hanging wheel and the slide rail, and facilitate the installation of the hanging wheel .
