A guide cavity 7 is provided inside the support frame 1, coaxially distributed with it. At least two lifting drive mechanisms 2 are evenly distributed around the axis of the support frame 1 on the side wall of the guide cavity 7.

The sleeve 3 is an arc-shaped groove structure coaxially distributed with the guide cavity 7, and every two sleeves 3 form a clamping group. The two sleeves 3 in the same clamping group are symmetrically distributed with respect to the axis of the guide cavity 7. At the same time, there are at least two clamping groups, which are distributed from top to bottom along the axis of the guide cavity 7. The shaping head 5 is located directly above the support frame 1 and is coaxially distributed with the guide cavity 7. The shaping head 5 is connected to the upper end face of the support frame 1 through the pressing mechanism 4. The drive circuit 6 is connected to the outer side of the support frame 1 and is electrically connected to the lifting drive mechanism 2, the sleeve 3, the pressing mechanism 4, and the shaping head 5 respectively.

[0023] The shaping head 5 includes a bearing base plate 51, a guide plate 52, a pressing plate 53, a driving guide rail 54, a temperature sensor 55, and an electric heating wire 56. The guide plate 52 is an inverted circular table-shaped hollow tubular structure. The bearing base plate 51 is embedded in the guide plate 52 and is a circular plate-shaped structure coaxially distributed with the guide plate 52. The outer side surface of the bearing base plate 51 is connected to the inner side surface of the guide plate 52. The upper end surface of the bearing base plate 51 is connected to the pressing mechanism 4 and is coaxially distributed. The outer side surface of the guide plate 52 is provided with at least two driving guide rails 54 distributed along the generatrix direction of the guide plate 52. The driving guide rails 54 are embedded in the guide plate 52 and are flush with the outer side surface of the guide plate 52. The number of the pressing plates 53 is consistent with the number of the driving guide rails 54. Each driving guide rail 54 is connected to the rear side surface of a pressing plate 53.

[0024] The driving guide rail 54 is a linear guide rail with any one of a screw mechanism, a gear and rack mechanism, and an electric telescopic rod as a power mechanism. The driving guide rail 54 is connected to the pressing plate 53 through a sliding block 57. The sliding block 57 is an “L”-shaped slot structure, which is covered on the upper end surface and the rear side surface of the pressing plate 53 and is connected to the upper end surface and the rear side surface of the pressing plate 53. A pressure sensor 58 is arranged at the position where the sliding block 57 is connected to the upper end surface of the pressing plate 57.

[0026] Further optimization is that the adjacent two pressing plates 53 are connected through an elastic connecting belt 50 and form a closed ring structure coaxially distributed with the guide plate 52.

[0027] Through the elastic connecting belt, on one hand, the synchronization of the pressing plates during the pressing and lifting can be coordinated to some extent, and the operation precision can be improved; on the other hand, the stress difference of the PFA material between the adjacent two pressing plates can be prevented, so that the PFA material is not seriously uneven after being formed.

[0028] Through the synchronous operation of the multiple pressing plates, on one hand, the flexibility of the equipment replacement and adjustment during the operation of the pressing plates can be improved, and the defect that all the pressing plates need to be replaced due to the local structure damage of the pressing plates can be avoided; on the other hand, the gap between the multiple pressing plates can be adjusted, so that the needs of the bending operation of the pipes with different diameters can be effectively met.

The driving telescopic columns 42 are at least two, embedded in the upper end surface of the bearing keel 41 and evenly distributed around the axis of the bearing keel 41. The outer side surface of the driving telescopic column 42 is hinged with the upper end surface of the bearing keel 41 through the turnover mechanism 43, and the lower end surface is hinged with the upper end surface of the bearing base plate 51 of the shaping head 5 through a hinge. The axis of the driving telescopic column 42 intersects with the axis of the bearing keel 41 and forms an angle of 10°-60°. The intersection point between the axis of the driving telescopic column 42 and the upper end surface of the bearing base plate 51 and the axis of the bearing base plate 51 is 1 / 5-4 / 5 of the radius of the bearing base plate 51. The outer side surface of the driving telescopic column 42 is provided with an inclination sensor 44, and the driving telescopic column 42 and the upper end surface of the bearing base plate 41 are connected through a pressure sensor 58. The turnover mechanism 43, the inclination sensor 44 and the pressure sensor 58 are electrically connected with the driving circuit 6.

[0030] Through the multiple driving telescopic columns driving the pressing operation at the same time, on one hand, the stability of the driving force of the pressing operation and the adjustment range of the driving force can be improved; on the other hand, through the multiple-point synchronous driving of the bearing base plate, the uniformity of the stress of the bearing base plate during the operation can be effectively improved. The driving force state is monitored by the pressure sensor, and then the actual working state of each driving telescopic column is adjusted according to the actual stress state of each pressure sensor, so that the working precision and the adjustment flexibility of the pressing operation can be further improved.

[0031] The turnover mechanism and the inclination sensor arranged at the same time can realize the flexible adjustment of the working position of the driving telescopic column, so that the needs of the equipment operation under different processing conditions can be effectively met. In addition, the driving direction of the driving telescopic column can be adjusted to indirectly adjust the actual output value of the pressing driving force.

[0032] Further optimization is that the drive telescopic column 42 can be any one of an electric telescopic column, a hydraulic telescopic column, or a pneumatic telescopic column.

[0033] Furthermore, the jacket 3 includes a bracket 31, elastic pads 32, a horizontal drive mechanism 33, a temperature sensor 55, a pressure sensor 58, a connecting buckle 34, and an electromagnet 35. The bracket 31 is a groove-shaped structure with an arc-shaped cross-section, and its outer side is connected to the lifting drive mechanism 2 through at least two horizontal drive mechanisms 33. The axes of the horizontal drive mechanisms 33 are perpendicular to and intersect with the axes of the guide cavity 7 and the bracket 31, and each horizontal drive mechanism 33 is evenly distributed from top to bottom along the axis of the bracket 31. Several elastic pads are provided inside the front end face of the bracket 31. The bracket 31 is equipped with at least one temperature sensor 55, with the temperature sensor 55 located at the midpoint of the bracket 31. The pressure sensor 58 is located at the connection between the horizontal drive mechanism 33 and the bracket 31. The horizontal drive mechanism 33, the temperature sensor 55, and the pressure sensor 58 are all electrically connected to the drive circuit 6. Several connecting buckles 34 and electromagnets 35 are connected to the front end face of the bracket 31, symmetrically distributed on both sides of the axis of the bracket 31, and evenly distributed from top to bottom along the axis of the bracket 31. The electromagnets 35 are connected in parallel and are all electrically connected to the drive circuit 6.

[0034] The horizontal drive mechanism can drive the bracket to work in the horizontal plane, thereby achieving the purpose of clamping and positioning the pipe through the two clamps; at the same time, during the clamping and positioning process, on the one hand, the electromagnet can be used to assist in positioning with magnetic force; on the other hand, the elastic pads can reduce the damage to the pipe caused by the bracket.

[0035] Meanwhile, during the clamping and positioning process, the temperature sensor can detect the temperature of the pipe and, together with the electric heating wire of the forming head, can heat or keep the PFA material warm.

[0036] In a further optimized configuration, the connecting buckles 34 of the brackets 31 of the two clips 3 in the same working group are connected by straps 36.

[0037] The straps can also help improve the stability of the clamp for holding and positioning the pipe.

[0038] In this embodiment, the driving circuit 6 is a circuit system based on a programmable controller. The driving circuit also includes, but is not limited to, any one or more of the following common control interfaces: display, buttons, potentiometer, and keyboard.

[0039] In its specific implementation, this invention first assembles the supporting frame, lifting drive mechanism, clamp, pressing mechanism, shaping head, and drive circuit that constitute this invention to obtain a processing device for finished products.

[0040] When the working operation is carried out, first, the pipe to be processed is clamped and positioned by the jacket, and the pipe axis is vertically distributed with the horizontal plane, and the upper end surface of the pipe is above the upper end surface of the bearing frame, then the plastic head is driven by the pressing mechanism to press down, the plastic head is uniformly pressed into the upper end surface of the pipe to be processed, and the guide plate outside the plastic head is in contact with the inner side of the PFA material lining, and during the pressing process of the plastic head, the inclined outer surface of the guide plate is used to preliminarily bend the PFA material lining, and at the same time, the driving guide rail drives the pressing plate to synchronously press down, and the PFA material lining after preliminary bending is finally bent and positioned by the pressing plate, so as to complete the folding and covering of the PFA material lining on the flange outside the pipe end surface, and the PFA material lining after bending can be continuously pressed and positioned to improve the stability of the connection between the PFA material lining and the flange.

[0041] In addition, during the working operation, the heating mechanism such as the electric heating wire provided by the jacket and the plastic head is used to heat or heat preservation of the pipe to be processed and the PFA material, so as to improve the processing efficiency and reduce the structural defects such as uneven thickness, cracks and even breakage of the PFA material during bending; at the same time, the driving force during the operation can be detected by the pressure sensor, and the working driving force can be accurately controlled to improve the working efficiency, prevent the instability of the connection between the PFA material and the flange caused by insufficient driving force, and prevent the structural damage of the PFA material caused by excessive stress.

[0042] The novel equipment has simple structure, high integration and modularization, can efficiently bend and form the PFA material lining layer at both ends of the pipe, effectively ensure that the PFA material lining reliably covers the outside of the flange at both ends of the pipe, and overcome the defects such as uneven thickness, cracks and even breakage of the PFA material lining layer at the bending part during the bending of the PFA material lining by the traditional equipment, so as to effectively improve the stability and reliability of the connection and positioning between the PFA material lining and the pipe.
