Detailed Description

As shown in figure 1, the multi-angle batch bending machine for the pipes comprises a support 1, wherein a driving mechanism is installed on one side of the support 1, and a locking mechanism is installed on the other side of the support 1.

As shown in fig. 2-4, the driving mechanism includes a fixed sheave assembly 2, the fixed sheave assembly 2 includes a plurality of sheaves, the sheaves are fixedly assembled into a whole at intervals by a fixed shaft, and the fixed shaft is fixedly installed on the left and right installation plates of the bracket 1. The lower end of the fixed sheave assembly 2 is provided with a movable sheave assembly 3, the structure of the movable sheave assembly 3 is the same as that of the fixed sheave assembly 2, and the movable sheave assembly 3 comprises a plurality of sheaves and a fixed shaft, wherein two ends of the fixed shaft are rotatably arranged on a fixed plate 4, the upper end of the fixed plate 4 is rotatably arranged on the support 1 through a short shaft, and the axis of the short shaft coincides with that of the fixed sheave assembly 2. The short shaft is located the other end of fixed plate 4 and is fixed with gear 5.1, and gear 5.1 one side and rack 5.2 mesh, and rack 5.2 slides through slider 5.3 and sets up on slide rail 5.4 and through first cylinder 5.5 drive and reciprocate. When the first cylinder 5.5 contracts, the rack 5.2 drives the gear 5.1 to rotate clockwise, the short shaft fixed with the gear 5.1 drives the fixing plate 4 to rotate clockwise, and thus the movable sheave assembly 3 can rotate clockwise around the axis of the fixed sheave assembly 2.

As shown in fig. 3, the locking mechanism includes a pressing plate 6, the lower end of the pressing plate 6 is provided with positioning slots corresponding to the fixed sheave assembly 2 or the movable sheave assembly 3 in number, sliding blocks are fixed on the left and right of the pressing plate 6, the sliding blocks are slidably arranged in the slide ways of the sliding frame 7, and the sliding frame 7 is fixed on the support 1.
