As shown in FIG. 9 , the mold core 35 has an elongated shape as a whole, and the mold core 35 has a rolling side, and the rolling side is adapted to fit with the pressing roller 372 . As shown in FIG. 3 , when the U-folding device 3 is in operation, the flat blank 91 is first placed on the material seat 34 , and then the hydraulic push rod 363 works to drive the swing frame 362 around it.

It should be noted that the degree of rebound of the flat blank 91 is affected by its own material and the processing environment. When the material or processing environment of the flat blank 91 is different, the degree of rebound of the flat blank 91 is also different. The rolling angle of the pressing roller 372 also needs to be changed. Since the pressing roller 372 in this patent is controlled by a servo motor, the servo motor can freely control the rotation angle of the pressing roller 372, thereby meeting different processing requirements of the equipment. In fact, the back of the bending equipment described in this patent is also provided with a welding device for the lower ring of the inner tank, and the U-shaped lower ring of the inner tank 92 obtained by bending will be sent to the welding equipment for the lower ring of the inner tank for welding processing; There will be a measuring device in the welding equipment for the lower ring of the liner to measure whether the lower ring 92 of the U-shaped liner is standard.

In this patent, the mold core 35 and the material seat 34 are automatically clamped through the mold clamping drive member 36, and then the left bending assembly 31 and the processing component 37 on the right bending assembly 32 are rotated and bent synchronously. The production of the flat blank 91 takes place in one go. In view of the different material springback coefficients, since the rotary driving member 374 in this patent is a driving motor, by controlling the rotation angle of the driving motor, the rolling stroke of the pressing roller 372 on the outer contour of the mold core 35 can be effectively changed to ensure high efficiency The U-shaped inner liner lower ring 92 that meets the requirements is processed, thereby improving the qualification rate of the product and the production efficiency. The rotary drive member 374 in this patent can also use a servo oil cylinder. However, compared with the servo oil cylinder, the driving motor has higher control precision and simple operation, and can be precisely controlled only by configuring the electrical circuit.

When the pressing roller 372 is rolling the flat blank 91, since the fixing points of the pressing roller 372 are at both ends of the pressing roller 372, when the pressing roller 372 is rolled, the two ends of the pressing roller 372 exert a greater pressure on the flat blank 91, The pressure on the flat blank 91 in the middle of the pressing roller 372 is relatively small, which will cause the unbalanced shape of the rolled U-shaped liner pressing ring 92 due to the unbalanced force of the flat blank 91, resulting in an unusable product. The pre-pressing assembly 38 can apply a certain strength of pre-tightening force to the pressing roller 372, so that the force on the pressing roller 372 on the flat blank 91 is the same everywhere, so that the pre-pressing assembly 38 can make the flat blank The bending angle and bending shape of 91 are more accurate, which is beneficial to improve the bending quality. Providing the pressing groove 3811 can make the pressing block 381 wrap around the outer edge of the pressing roller 372, so that the pressing roller 372 can be fully stressed, thereby improving the bending quality.

Further, the processing connecting plate 373 is also provided with an outer support 383, as shown in Figs. When the flat blank 91 is placed on the material seat 34, the outer end of the flat blank 91 is supported; at the same time, when the flat blank 91 is processed, the outer support 383 moves with the processing connecting plate 373, The outer support 383 supports the flat blank 91 in real time to prevent the flat blank 91 from slipping and affecting processing.

Since the mold clamping drive 36 in this patent includes a hydraulic push rod 363, the hydraulic push rod 363 has limited running accuracy, resulting in an uncertain operating position of the mold core 35; this patent uses the positioning pin 351 and the positioning seat 333; When the mold is closed, the positioning pin 351 will be located in the positioning groove 334 at the same time, so as to restrict the continuous downward movement of the mold core 35, and the positioning groove 334 restricts the movement of the positioning pin 351 to position the mold. At the same time, it prevents the mold core 35 from hitting the flat blank 91 and the material seat 34 due to the accuracy of the hydraulic push rod 363, causing the flat blank 91 or material holder 34 is damaged.
