The hollow guide rail processing technology process comprises the following steps of cutting: cutting the steel material into required dimensions; stamping: putting the cut steel into a die, and stamping and forming; punching: punching the punched steel; surface treatment: the machined steel is subjected to surface treatment to ensure that the surface is smooth and corrosion-resistant.
Some prior art devices for processing hollow guide rails, such as the automatic punching production line for hollow guide rails disclosed in chinese patent publication No. CN104741441B, include: the plate bar discharging machine, the cold roll forming machine, the tracking cutting machine, the longitudinal conveyor and the transverse conveyor belt are sequentially arranged along the conveying direction, the two punching machines are arranged on the left side and the right side of the transverse conveyor belt at intervals in a front-back staggered mode, two supporting wheel guide rail placing platforms are arranged above the transverse conveyor belt at intervals, each supporting wheel guide rail placing platform is respectively aligned with one punching machine and provided with a pushing mechanism, a material blocking mechanism is arranged behind the first supporting wheel guide rail placing platform along the forward conveying direction of the hollow guide rail, and a jacking and transverse moving mechanism is arranged below the transverse conveyor belt.
The traditional hollow guide rail processing equipment has the advantages that the punch used for stamping the steel is of a fixed shape, namely, the sheet steel is changed into a 'several' -shaped steel by virtue of the cooperation between the punch of the fixed shape and the bottom die; after the stamping starts, the bottom of the punch is firstly contacted with the steel, the steel cannot be tightly attached to the top surface of the bottom die in the pressing process, even the steel can be separated from the top surface of the bottom die to form a bulge (shown in figure 2), and the steel can be pressed on the top surface of the bottom die by the stamping head only when the stamping is close to the end; thus, redundant materials appear in the arc-shaped area in the middle of the steel, and the thickness of the part is increased; the two side edges of the steel material inevitably form shrinkage, so that the shape of the formed steel material does not reach the standard; in addition, because the steel is not limited in the stamping process, horizontal deflection can occur, and the two sides of the stamped steel are asymmetric; in order to avoid such a situation, in the prior art, the steel can only be punched for multiple times, that is, each bending part is punched independently, and according to the shape of the hollow guide rail shown in fig. 1, at least five times of punching are needed, and the steel needs to be positioned before each punching, which is not beneficial to rapid production. Based on the above, how to improve the speed of stamping production under the condition of ensuring that the shape of the hollow guide rail meets the standard is a technical problem which needs to be solved by the technicians in the field.
