Technical Field

[0001] The utility model relates to the technical field of stainless steel pipe processing, and more specifically, to a stainless steel pipe port shaping device. Background Art

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4 As shown, a stainless steel pipe port shaping device of an embodiment of the utility model includes a base 1, two shaping mechanisms are correspondingly arranged at both ends of the base 1, a support seat 2 is arranged at the center of the two shaping mechanisms, a pipe supporting seat 20 is fixedly arranged in the middle of the support seat 2, and a plurality of limit units 3 are equidistant and spaced apart on the front and rear sides, and a linkage mechanism is built into the support seat 2, which is linked with each limit unit 3 to control each limit unit 3 to clamp or release the pipe.

[0021] When in use, the pipe to be shaped is placed on the support seat 2, and the linkage mechanism is used to control each limit unit 3 to synchronously clamp the pipe, and then the shaping mechanisms at both ends of the base 1 are started to shape the two ends of the stainless steel pipe;

[0022] The utility model can control each limiting unit 3 to synchronously clamp or release the pipe through the linkage mechanism, and the limiting unit 3 can adapt to the clamping and limiting of pipes of different sizes, effectively improving the use flexibility and practicality of the device.

[0023] The limiting unit 3 includes a column 30, a sliding rod 31 is movably provided on the top of the column 30, the inner end of the sliding rod 31 is connected to an inclined plate 32 and the outer end is connected to a limiting ring 33, the outer ring of the sliding rod 31 is located between the limiting ring 33 and the column 30 and is sleeved with a first spring 34; a linkage portion 35 is also extended from the outer end of the sliding rod 31 and a guide column 36 is fixedly provided on the linkage portion 35, and the support seat 2 is provided with a U-shaped seat 21 on the outside of each column 30, and a linkage rod 22 is rotatably provided on the inner side of the U-shaped seat 21, and a U-shaped groove 23 adapted to the linkage portion 35 is formed on the top surface of the linkage rod 22, and the U-shaped groove 23 has two corresponding strip grooves 24 adapted to the guide column 36.

[0024] When in use, when it is necessary to clamp the pipe fittings, each linkage rod 22 is controlled to rotate with the connection with the U-shaped seat 21 as the axis. The rotation process is that the upper end of the linkage rod 22 rotates toward the side of the column 30 and the lower end rotates away from the side of the support seat 2. The linkage rod 22 rotates through the cooperation between the strip groove 24 and the guide column 36 to drive the linkage part 35 to move. The linkage part 35 drives the slide bar 31 to slide toward the inner side of the support seat 2 and causes the first spring 34 to be in a compressed state. The slide bar 31 slides inward and drives the inclined plate 32 to move to clamp the pipe. The steel pipe is stably clamped by multiple limit units 3.

[0025] When the clamping of the pipe fitting needs to be cancelled, each linkage rod 22 is controlled to rotate and the first spring 34 is released. At this time, each inclined plate 32 moves away from the pipe side to cancel the clamping of the pipe fitting.

[0026] The linkage mechanism includes a cavity 4 formed in the support seat 2, a gear shaft 40 is rotatably arranged between the left and right inner walls of the cavity 4, and movable columns 41 are movably penetrated through the front and rear inner walls of the cavity 4 at the corresponding positions of each linkage rod 22, and the inner ends of the movable columns 41 are provided with tooth grooves 42 adapted to the gear shaft 40, and the outer ends are provided with push plates 43 matched with each linkage rod 22; one end of the gear shaft 40 extends through to the outside of the support seat 2 and is connected to a turntable 5, the outer ring of the gear shaft 40 is located on the inner side of the turntable 5 and is fixed with a retaining ring 50, and the inner side of the retaining ring 50 is slidably provided with a first chuck 51, the outer ring of the gear shaft 40 is located between the retaining ring 50 and the first chuck 51 and is sleeved with a second spring 52, and a second chuck 53 is provided on the side wall of the support seat 2 at the corresponding position of the first chuck 51.

[0027] When in use, the turntable 5 is rotated to drive the gear shaft 40 to rotate. The gear shaft 40 rotates and engages with the tooth grooves 42 at the inner ends of the movable columns 41 to synchronously drive the outer ends of the movable columns 41 to extend outward. The extension of the movable columns 41 drives the push plates 43 at the outer ends thereof to extend out and contact the lower end of the linkage rod 22. The push plates 43 push the lower end of the linkage rod 22 to cause the linkage rod 22 to rotate, thereby controlling the inclined plate 32 to clamp the pipe fittings.

[0028] When it is necessary to cancel the clamping limit of the pipe fitting, the rotating disk 5 is rotated to reset the movable columns 41 and the push plates 43. At this time, the energy stored in the first springs 34 is released and the linkage rods 22 and the inclined plate 32 are reset. At this time, the clamping limit of the inclined plate 32 on the pipe is eliminated, and the pipe fitting can be taken and placed.

[0029] Further, in the initial state, the first chuck 51 and the second chuck 53 are in a limited clamping state, specifically, a plurality of clamping grooves are equidistantly and circumferentially provided on the outer side of the second chuck 53, and each clamping block is located in a corresponding clamping groove when the first chuck 51 and the second chuck 53 are in the limited clamping state, and a clamping block adapted to each clamping groove is provided on the inner side of the first chuck 51, and the first chuck 51 and the gear shaft 40 are in a sliding fit, so when the first chuck 51 and the second chuck 53 are in the limited clamping state, the gear shaft 40 cannot rotate, and the rotation of the gear shaft 40 can be locked so that each limiting unit 3 remains in a locked state or an unlocked state, thereby ensuring the stability of the device in use;

[0030] The clamping stability between the first chuck 51 and the second chuck 53 is ensured by the second spring 52. When the rotation lock of the gear shaft 40 is released, the first chuck 51 is controlled to overcome the elastic force of the second spring 52 and slide along the gear shaft 40 toward the side of the second chuck 53, prompting each clamping block to withdraw from the slot to cancel the limiting clamping of the two. At this time, the gear shaft 40 can be rotated and each limiting unit 3 can be controlled to switch the working state. After the gear shaft 40 rotates and completes the state switching of the limiting unit 3, the first chuck 51 is released and the first chuck 51 retreats to the initial position due to the release of the stored energy of the second spring 52 and forms a limiting clamping with the second chuck 53 again, thereby locking the gear shaft 40.

[0031] Two hydraulic push rods 10 are correspondingly arranged on the top surface of the base 1 and located at the position of the support seat 2 , and the output shafts of the hydraulic push rods 10 are drivingly connected to the lower bottom surface of the support seat 2 .

[0032] When in use, the two hydraulic push rods 10 are used to control the lifting and lowering of the support base 2, so that the support base 2 can adjust its height according to the pipe to be shaped, so as to adjust the pipe to the optimal processing position.

[0033] The shaping mechanism includes a sliding die base 11 fixed on the base 1, a sliding template 12 arranged on the sliding die base 11, a servo motor 13 arranged on the sliding template 12, and a shaping sleeve 14 connected to the servo motor 13. The sliding template 12 is connected to a power source 15 for driving it to slide back and forth along the sliding die base 11. When in use, after the pipe is placed on the support base 2, two power sources 15 (preferably electric push rods) drive the two sliding templates 12 to slide synchronously and toward each other along the corresponding sliding die base 11. At this time, the two shaping sleeves 14 move and push the pipe to the center position. At this time, the linkage mechanism controls each limit unit 3 to clamp the pipe, and then starts the two servo motors 13 and drives the two shaping sleeves 14 to shape the two ends of the pipe. After the processing is completed, each sliding template 12 is controlled to retract to the initial position.

[0034] The electrical components mentioned in this article are all connected to an external main controller and 220V mains electricity, and the main controller can be a conventional known device for controlling a computer or the like.
