DETAILED DESCRIPTION
[0031] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.
[0032] Please refer to Figures 1-7 The present application provides a technical solution: a tent supporting steel pipe electric bending equipment, comprising,
[0033] The processing table 1 is provided with a processing platform 11 on the top, a set of sliding grooves are arranged on the top of the processing platform 11, and a conveying seat 2 is arranged in the sliding groove. A pushing motor 4 is arranged between the conveying seats 2. A bending frame 3 is arranged on the top of the processing table 1 between the conveying seats 2. A set of limiting frames 32 are movably arranged on the bending frame 3, which are used to abut against the edge of the steel pipe to limit the bending distance.
[0034] The conveying seat 2 is movably provided with a clamping frame 22 connected with a limiting tube 5 on one side. The limiting tube 5 is provided with a connecting frame 51 for clamping and positioning the steel pipe on one end. A transmission disc 52 is movably arranged on the outer side of the limiting tube 5, which is used to abut against the two ends of the steel pipe to assist in limiting. When the steel pipe needs to be bent, the steel pipe can be clamped outside the limiting tube 5. Before the bending process, the polishing ring on the outer side of the clamping pressing plate 56 can be used to polish and clean the inside of the steel pipe by means of the rotating shaft 53, so as to ensure the consistency of clamping. During the clamping process of the steel pipe, the height of the bending pressing plate 41 and the pressing roller 34 can be adjusted to keep them on the same horizontal line, so as to reduce the accidental small deviation during the bending process of the steel pipe, ensure the consistency of the steel pipe processing, and reduce the generation of defective products in the subsequent assembly process.
[0035] As shown in Figure 5 and Figure 6 , a telescopic rod is installed on one end of the connecting frame 51 and arranged in the limiting tube 5. A rotating shaft 53 is rotatably arranged in the connecting frame 51. A driving motor 531 is installed on the side of the connecting frame 51 away from the limiting tube 5. The rotating shaft 53 rotates with the output end of the driving motor 531. The driving motor 531 drives the rotating shaft 53 to rotate circumferentially, so as to make the external compression frame 55 rotate circumferentially in the steel pipe.
[0036] A plurality of positioning end blocks 54 are mounted on the rotating shaft 53, and telescopic shafts 541 are mounted at both ends of the positioning end blocks 54. A compression frame 55 is mounted at the top end of the telescopic shaft 541. The compression frame 55 is composed of a group of discs and a plurality of telescopic plates. A clamping pressure plate 56 is connected to the outer end of the compression frame 55. The clamping pressure plate 56 is used to abut against the inner wall of the steel pipe. During the circumferential movement of the compression frame 55, the steel pipe inside can be cleaned by the clamping pressure plate 56, which can reduce the offset and tilt of the steel pipe during the clamping of the connecting frame 51.
[0037] As shown in Figure 6 , the compression frame 55 is internally provided with an expansion pipe 551. The clamping pressure plate 56 is internally provided with a hollow structure and is in communication with the expansion pipe 551 at the bottom. A polishing ring can be clamped at the outer end of the clamping pressure plate 56. The polishing ring is used to abut against the inner wall of the steel pipe and follow the circumferential movement of the rotating shaft 53. This can reduce the small offset during clamping. The rotating shaft 53 moves circumferentially under the cooperation of the driving motor 531. The steel pipe inside can be polished under the action of the polishing ring clamped on the outer side of the clamping pressure plate 56. This can reduce rust and the accumulation of debris at the clamping position.
[0038] In addition, it should be noted that the polishing ring and the grid pad can be squeezed and rubbed against each other when the compression frame 55 is rotated to the position between the butt joint plates 57. The debris generated by polishing can be quickly shaken off. The steel pipe inside can be continuously cleaned. The accumulation of metal debris can affect the subsequent polishing efficiency. The connecting frame 51 can be rotated by 90 degrees. The steel pipe inside can be polished by the polishing ring. The steel pipe can be kept in a straight state during the auxiliary support of the connecting frame 51. The offset can be reduced.
[0039] As shown in Figure 7 , the connecting frame 51 is connected to the connecting plate 58 at both ends of the outer wall. A plurality of feeding shafts 581 are mounted on the connecting plate 58. The feeding shaft 581 is externally provided with a hollow limiting end block 582. The limiting end block 582 is semispherical and externally provided with a plurality of annular grooves. A group of butt joint plates 57 are mounted on the inner wall of the connecting frame 51. The butt joint plate 57 is arc-shaped and elastic on one side. The butt joint plate 57 is internally provided with a reset pipe 571. A plurality of conveying pipes are mounted on the reset pipe 571 and penetrate the connecting frame 51 and the connecting plate 58. The limiting end block 582 is in communication with the conveying pipe. During the clamping of the steel pipe, the connecting frame 51 can be conveyed to the position inside the steel pipe. The connecting frame 51 can abut against the position prone to deformation at both ends during the bending of the steel pipe. The connecting frame 51 can play a supporting role. The bending angle inconsistency during the subsequent production process can be reduced. The deviation of the bending angle of the same batch of steel pipes can be effectively reduced. The influence on the subsequent assembly can be reduced.
[0040] As shown in Figure 7As shown, a symmetrically arranged snap-in groove is provided on one side edge of the arc-shaped docking plate 57, and a grid pad is provided in the snap-in groove for squeezing and cleaning debris with the clamping pressure plate 56 during the circular motion. The grid pad can clean the surface of the grinding ring, reduce the amount of debris and dirt remaining on the grinding ring, and allow the debris to fall into the inside of the steel pipe for subsequent throwing out and cleaning.
[0041] like Figure 2 As shown, a group of transmission plates 31 are movably provided at the top of the bending frame 3, a pair of lifting shafts are provided at the top of the transmission plate 31, a limit frame 32 is provided at the top of the lifting shaft, a control motor 33 is installed on the top of the limit frame 32, and a movable plug rod is provided at the bottom of the control motor 33 that passes through the limit frame 32, and a clamping roller 34 is provided on the outside of the movable plug rod. The outer wall of the clamping roller 34 is in the shape of an inwardly concave arc surface, which is used to rest on the outer wall of the steel pipe. Under the control of the control motor 33, the position of the clamping roller 34 can be fitted to the outer wall of the steel pipe, thereby reducing the accidental flattening of the steel pipe in the local area during the bending process, and can also be quickly adjusted when replacing steel pipes of different models, and has good applicability.
[0042] like Figure 2 and Figure 3 As shown, a straight groove is provided at the outer end of the limit frame 32, and a buffer pad 35 is clamped inside the straight groove. A number of elastic sheets are provided on the side of the buffer pad 35 close to the pressing roller 34 to reduce the adhesion of dirt and debris on the surface of the pressing roller 34, which may cause indentations and scratches on the surface of the subsequent steel pipe. During the bending process, under the influence of the interaction force, the pressing roller 34 can be pushed to rotate outside the movable plug rod, and the elastic sheets on the surface of the buffer pad 35 can play a cleaning role, reducing the situation where dirt or metal chips remaining on the surface leave indentations or scratches on the surface of the steel pipe.
[0043] like Figure 4 As shown, a group of pushing tubes 21 are installed on the top of the conveying seat 2. The height of the pushing tubes 21 is adjustable. The clamping frame 22 is installed at one end of the pushing tube 21. Both ends of the clamping frame 22 are provided with hinged plates. The limiting tube 5 is movably arranged inside the hinged plate. The height of the pushing tube 21 can be adjusted. When steel pipes of different sizes are replaced, the clamping height of the steel pipe can be adjusted to be kept on the same horizontal line with the clamping roller 34, thereby reducing the accidental occurrence of small offsets during the bending process of the steel pipe.
[0044] like Figure 4 As shown, a push rod motor 23 is installed at one end of the clamping frame 22, and a rubber pad is provided on the conveying end of the push rod motor 23, and the rubber pad is used to press against one end of the limiting tube 5 to play a locking role. With the help of the push rod motor 23, the rubber pad can be pressed against one end of the limiting tube 5, which can play a locking role during the clamping and grinding process, thereby reducing the shaking of the steel pipe.
[0045] likeFigure 1 As shown, the push motor 4 output end is mounted with a detachable bending pressing plate 41, which can be adjusted according to the actual situation.
[0046] Working principle: first, when the steel pipe needs to be bent, the steel pipe can be clamped outside the two end limiting pipes 5, and before bending, the inside of the steel pipe can be polished by the polishing ring outside the clamping pressing plate 56 with the help of the rotating shaft 53, to ensure the consistency of clamping, and during the clamping process of the steel pipe, the height of the bending pressing plate 41 and the pressing roller 34 can be adjusted to keep the same horizontal line, reduce the accidental situation of small deviation during the bending process of the steel pipe, ensure the consistency of the steel pipe processing, reduce the generation of defective products in the subsequent assembly process, and before clamping the steel pipe, the steel pipe can be abutted between the transmission discs 52, which can limit the steel pipe, and at this time the connecting frame 51 can enter the inside of the steel pipe, the telescopic shaft 541 can be fed outward and the rotating shaft 53 can rotate under the cooperation of the driving motor 531, which can polish the inside of the steel pipe under the action of the polishing ring clamped outside the clamping pressing plate 56, reduce the rust and the situation of residual debris at the clamping position, and during the circular motion, the compression frame 55 can be rotated to the butt joint plate 57, so that the polishing ring and the grid mat are extruded and rubbed, the debris generated by polishing can be quickly shaken off, and the inside of the steel pipe can be continuously cleaned;
[0047] Then, after finishing cleaning the inside wall of the steel pipe, the inside of the steel pipe can be clamped by the single connecting frame 51, and the limiting pipe 5 moves in the clamping frame 22, so that the debris generated by polishing in the steel pipe is discharged, and during the clamping process, as the connecting frame 51 feeds into the inside of the steel pipe, it can be abutted at the position prone to deformation at both ends during the bending process of the steel pipe, which can play a supporting role and reduce the accidental situation of inconsistent bending angle in the subsequent production process.
[0048] Finally, after clamping, the push rod motor 23 can be reset to reduce the locking of both ends of the steel pipe, and the bending pressing plate 41 can be abutted on the steel pipe by the conveying end of the push motor 4, which can drive the steel pipe to deform, and the push tube 21 can also deform and move outward, reducing the interference of the steel pipe bending, and under the control of the control motor 33, the position of the pressing roller 34 can be fitted to the outer wall of the steel pipe, reducing the accidental situation of local flattening of the steel pipe during the bending process, and under the influence of the interaction force, the pressing roller 34 can be pushed to rotate outside the movable rod, and the elastic sheet on the surface of the buffer pad 35 can play a cleaning role, reducing the situation that dirt or metal chips on the surface leave marks or scratches on the surface of the steel pipe.
[0049] While embodiments of the application have been shown and described, it is to be understood that the embodiments described are merely exemplary of the principles and application of the present application. Numerous modifications and adaptions can be effected without departing from the spirit and scope of the present application, which is not limited to the exact construction and arrangement described.
