As shown in fig. 9, the mold core 35 is a long strip, and the mold core 35 has a rolling side adapted to fit with the pressing roller 372. As shown in fig. 3, when the U folding device 3 works, the planar blank 91 is first placed on the material seat 34, and then the hydraulic push rod 363 works to drive the swing frame 362 to rotate around the rotation connection point of the swing frame and the sub-seat body 361, so that the outer end of the swing frame 362 moves from top to bottom, and the mold core 35 at the outer end of the swing frame 362 abuts against the upper side of the planar blank 91 above the material seat 34, so as to perform mold closing. In this patent, in order to facilitate the display of the bent structure of the flat blank 91, in fig. 3-5, the left bending assembly 31 and the right bending assembly 32 of the single U-folding device 3 respectively display the structure of the flat blank 91 in the bent state and the non-bent state. As shown in fig. 4 and 5, when the machining assembly 37 works, the machining seat 371 rotates to drive the pressing roller 372 to abut against the rolling side of the mold core 35, and rolls along the outer contour of the rolling side, so as to bend one end of the planar blank 91. In the patent, the planar blank 91 is bent into the U-shaped inner container lower ring 92, that is, the corner part of the U-shaped inner container lower ring 92 is arc-shaped, so that an arc surface is arranged on the rolling side of the mold core 35, and the angle of the arc surface is at least 90 degrees, so as to adapt to the rolling processing of the pressing roller 372; in this embodiment, the angle of the arc surface is 180 degrees, so that the manufacturer can properly make the rolling angle of the pressing roller 372 exceed 90 degrees, thereby preventing the produced U-shaped liner lower ring 92 from being out of standard due to the rebound of the material of the flat blank 91, and setting the angle of the arc surface on the rolling side to 180 degrees, so as to provide a rolling space for the pressing roller 372. It should be noted that the resilience of the planar blank 91 is affected by the material and the processing environment of the planar blank 91, and when the material or the processing environment of the planar blank 91 is different, the resilience of the planar blank 91 is also different, and accordingly, the rolling angle of the pressing roller 372 needs to be changed for adaptation; and because compression roller 372 in this patent is controlled by servo motor, servo motor can freely control compression roller 372 pivoted angle to can satisfy the different processing demands of equipment. In fact, an inner container lower ring welding device is further arranged behind the bending device, and the bent U-shaped inner container lower ring 92 is sent to the inner container lower ring welding device for welding; the inner container lower ring welding equipment is provided with measuring equipment for measuring whether the U-shaped inner container lower ring 92 is standard or not, if the U-shaped inner container lower ring 92 is not standard, the bending deviation condition of the U-shaped inner container lower ring 92 is recorded, related data are sent into the bending equipment, and the bending equipment adjusts the rolling angle value of the pressing roller 372 according to the related data, so that closed-loop automatic adjustment is realized; in addition, the measuring device can also be arranged in the bending device disclosed in the patent, for example, on a conveying device or a blanking device behind the U folding device, and the measuring device can also realize closed-loop automatic adjustment.

It should be noted that, since the present patent is provided with the left bending assembly 31 and the right bending assembly 32, the left bending assembly 31 and the right bending assembly 32 work simultaneously to perform bending processing on the left and right ends of the planar blank 91 simultaneously.

This patent is through the compound die driving piece 36 realizes the compound die of mold core 35 and material seat 34 automatically, then buckles the processing subassembly 37 on assembly 31 and the right side assembly 32 through a left side and rotates in step and buckle the processing, once only realizes the manufacturing to plane blank 91. To the different circumstances of material coefficient of resilience, because the rotation driving piece 374 in this patent is driving motor, through control driving motor's turned angle, can effectively change the stroke of compression roller 372 rolling on mold core 35 outline, ensure that the efficient processing goes out the U-shaped inner bag lower ring 92 that meets the requirements to the qualification rate and the production efficiency of product have been improved. The rotary driving part 374 in the patent can also adopt a servo oil cylinder, but the driving motor is higher in control precision compared with the servo oil cylinder, and the operation is simple, and the precise control can be carried out only by configuring an electric circuit.

Further, a processing connecting plate 373 is arranged between the two processing seats 371, a pre-pressing assembly 38 is arranged on the processing connecting plate 373, and the pre-pressing assembly 38 comprises:

a pressing block 381 which is provided on the processing connecting plate 373 and abuts against the pressing roller 372; and

and the compression driving part 382 is connected with the compression block 381 and is used for providing compression force for the compression block 381.

As shown in fig. 6 to 8, the pressing driving member 382 is a servo cylinder disposed on the processing connecting plate 373, and the pressure of the servo cylinder can be adjusted according to the processing requirement; the pressing block 381 is driven by the motor push rod to move, and a pressing groove 3811 for accommodating the pressing roller 372 is formed in the pressing block 381. The compression roller 372 is at the both ends of the compression roller 372 when the plane blank 91 is rolled, because the fixed point of the compression roller 372 is at the both ends of the compression roller 372, when the compression roller 372 is rolled, the pressure of the two ends of the compression roller 372 to the plane blank 91 is large, the pressure of the middle part of the compression roller 372 to the plane blank 91 is relatively small, so that the shape of the U-shaped inner container pressing ring 92 rolled out due to the unbalanced stress of the plane blank 91 is not standard, and the product cannot be used. The pre-pressing assembly 38 can apply a pre-tightening force with a certain strength to the pressing roller 372, so that the acting force on the pressing roller 372 on the plane blank 91 is the same everywhere, and thus the bending angle and the bending shape of the plane blank 91 can be more accurate through the pre-pressing assembly 38, which is beneficial to improving the bending quality. The setting compress tightly groove 3811 can make the compact heap 381 cladding is along outside compression roller 372, makes compression roller 372 abundant atress, and then improves the quality of buckling.

Further, an outer seat 383 is further disposed on the processing connecting plate 373, as shown in fig. 7 and 8, the outer seat 383 is disposed outside the pressing roller 372, and the outer seat 383 is used for supporting the outer end of the planar blank 91 when the planar blank 91 is placed on the material seat 34; meanwhile, when the planar blank 91 is processed, the outer seat 383 moves along with the processing connecting plate 373, and the planar blank 91 is supported in real time by the outer seat 383, so that the planar blank 91 is prevented from slipping to influence the processing.

Because the mold closing driving part 36 comprises the hydraulic push rod 363, the running precision of the hydraulic push rod 363 is limited, so that the running position of the mold core 35 is uncertain; the positioning pin 351 and the positioning seat 333 are adopted; when the mold core 35 is completely closed, the positioning pin 351 is simultaneously located in the positioning groove 334 so as to limit the mold core 35 to continuously move downwards, and the positioning pin 351 is limited by the positioning groove 334 to position the mold core 35, so that the mold core 35 is fixed at an accurate position for bending; meanwhile, the die core 35 is prevented from impacting on the plane blank 91 and the material seat 34 due to the accuracy problem of the hydraulic push rod 363, and the plane blank 91 or the material seat 34 is prevented from being damaged.
