Here, the first arc roll 4 and the second arc roll 5 may be configured to be stationary, and at this time, the first arc roll 4 and the second arc roll 5 only need to be partially arc-shaped, and do not need to be designed to be cylindrical in the whole structure, and may also be configured to be rotatable, and at this time, the first arc roll 4 and the second arc roll 5 are both cylindrical.

The folded plate 6 is rotatably arranged on the support frame 1 or the first bearing plate 2, optionally, one end of the telescopic cylinder 9 is rotatably arranged on the support frame 1, the other end of the telescopic cylinder is rotatably arranged on the flat plate 62, and the folded plate 6 is rotated under the action of the telescopic cylinder 9. The folded plate 6 comprises a rotating frame 61 and a flat plate 62, the rotating frame 61 is rotatably arranged on the support frame 1 or the first bearing plate 2, the rotating frame 61 and the first arc-shaped rollers 4 are arranged in a one-to-one correspondence manner, and the flat plate 62 is connected with the rotating frame 61 in an oblique angle manner. The round roller 7 is arranged at the joint of the rotating frame 61 and the plate 62, the round roller 7 and the first arc-shaped roller 4 interact, and the round roller 7 rolls and presses the workpiece around the first arc-shaped roller 4 to form an outer end at b in the figure and the right in the figure 2. Preferably, the rotation axis of the circular roller 7 coincides with the rotation axis of the first arc-shaped roller 4, and the distance between the first arc-shaped roller 4 and the circular roller 7 is kept constant, so that the bending at the position b in fig. 2 is kept as uniform as possible, and the bending quality is improved.

In the present application, a preferred design scheme of the circular roller 7 is provided, specifically, as shown in fig. 4, the circular roller 7 includes a rotating shaft 71 and a plurality of bearings 72, the rotating shaft 71 is fixedly disposed on the folded plate 6, and the bearings 72 are sleeved on the rotating shaft 71. The round roller 7 is formed by combining the plurality of bearings 72, so that the size of the bearings 72 can be selected conveniently according to the types of workpieces, and the round roller is suitable for processing various workpieces; when part of the bearing 7 is damaged, the bearing can be replaced in a targeted manner without replacing the whole round roller, so that the embarrassment of replacing the whole round roller due to the damage of the part of the round roller 7 is avoided. On the basis, the positioning device shown in fig. 7 is designed to comprise a positioning wheel, the positioning wheel is sleeved on the rotating shaft 71 and is arranged between the bearings 72, and an annular arc groove corresponding to the workpiece is arranged on the outer side of the positioning wheel.

When the roller 7 is rotated until the workpiece abuts the second plane 83, the plate 62 is in a parallel position with the first plane 81 and clamps the workpiece, forming position c in fig. 2.

Because the machined part is tubulose, takes place deformation easily when the extrusion, so first loading board 2, second loading board 3, first arc roll 4, second arc roll 5, circle roll 7 and sketch plate 8 are equipped with the arc lumen that corresponds with the machined part, avoid the extrusion in-process, only carry out the bending processing to the evaporating pipe machined part, and can not cause the finished product surface to press from both sides and hinder, flatten unusual situation such as.

When the workpiece fixing device is used, the first bearing plate 2 and the second bearing plate 3 are opened, the workpiece shown in fig. 1 is placed on the first bearing plate 2, and then the first bearing plate 2 and the second bearing plate 3 are controlled to be close to each other, so that the middle part of the workpiece is fixed. Then, the control flap 6 is rotated, the circular roller 7, the first arc roller 4 and the second arc roller 5 interact to form an arc shape inside b in fig. 2, and then, subsequently, the circular roller 7 interacts with the first arc roller 4 to form an arc shape outside b in fig. 2. Thereafter, the flat plate 62 fixes the workpiece to the special-shaped plate 8, and is press-formed at c in fig. 2. And reversely controlling the folded plate 6, separating the first bearing plate 2 from the second bearing plate 3, and taking out the machined part to obtain a finished product.
