A kind of ladder -oriented track bending formation process

Abstract

The invention discloses a process for bending and forming a ladder guide rail. Steps 1: send the ladder guide rail into a bending forming device for the ladder guide rail; 2. set the top pressure and angle in advance according to the material of the processed profile; For the mold, give the profile a certain top pressure on the outside of the profile to make the middle section of the profile fully contact with the main body of the straight segment mold, and gradually form the required angle; 4. After the rotation, reshape to obtain the required ladder guide rail. The beneficial effects of the invention are as follows: the section size of the ladder guide rail profile is optimized; the material cost is saved; the bending deformation is carried out by means of numerical control roller bending, so as to ensure that the profile surface is not damaged.

Description

Technical field [0001] The invention involves the field of automation machinery, which is specifically for a bending process of a ladder guide rail. Background technique [0002] In recent years, with the continuous increase in urbanization, urban transportation has developed rapidly, urban transportation construction, and a large number of subway transportation projects have greatly driven the escalator industry. Using this process can not only produce high -quality metal profile products, but also improve the appearance quality of the product, greatly improve the utilization rate of board, thereby improving the market competitiveness of the enterprise. [0003] Market competition and product quality status: Under the pressure of market competition, all competitors participate in it. The size requirements of the product can generally meet the requirements of the customer, but it is difficult to do it in the same technical level. Doing fineness will inevitably bring the productio...

Problems solved by technology

[0005] The object of the present invention is to provide a bending forming process of ladder guide rails to solve the problem that the existing ladder guide rail bending forming device proposed in the above background technology cannot clamp the guide rails well, and the guide rails are easy to fall off and pop up during the bending process. People reposition the guide rails for bending, which wastes a lot of time. When bending thick guide rails, it is easy to cause the guide rails to fail to achieve the expected bending degree due to insufficient power when bending thicker guide rails, which affects the quality of the finished product.
