The first sliding frame 111 is rotatably provided with two groups of swing rods 112, each group of swing rods 112 includes four, and the four swing rods 112 are equidistantly distributed circumferentially on the first sliding frame 111. The side wall of the second fixed shell 109 is limited and slidably provided with four second sliding plates 113 equidistantly distributed circumferentially. The outer side surfaces of the four second sliding plates 113 are matched to form a circular ring. The second sliding plates 113 are rotatably connected to the adjacent swing rods 112, and the outer sides of the four second sliding plates 113 are installed with elastic sleeves 11 4. The elastic sleeve 114 is made of high temperature resistant material. A heating unit 115 is installed on the rear side of the right part of the support 1. The first sliding frame 111 is provided with a liquid circulation mechanism, which is used to cool the pipe fittings that have been processed. The fixed plate 1061 is provided with a swing mechanism, which is used for the reciprocating rotation of the second fixed shell 109, so that the four second sliding plates 113 can extrude the pipe fittings in multiple directions through the elastic sleeve 114, thereby improving the uniformity of the expansion change of the pipe fittings. The electric lifting platform 102, the electric slider 103, the first electric push rod 106, the second electric push rod 110, the heating unit 115, the liquid circulation mechanism and the swing mechanism are all electrically connected to the control console 101.

A first spring 203 is installed between the second sliding frame 202 and the bracket 104. The first spring 203 is sleeved on the adjacent second sliding frame 202. The left side surface of the second sliding frame 202 is set as an inclined surface, and the inclined surface of the second sliding frame 202 cooperates with the sliding ring 201. Under the operation of the third electric push rod 2, the four second sliding frames 202 clamp the pipe fittings in the center. When this clamping method is used to clamp pipe fittings of different diameters, the center line of the pipe fitting remains unchanged, which is convenient for the subsequent expansion processing of the clamped pipe fittings, thereby improving the applicability of the present invention.
[0033] Reference Figure 4 and Figure 5 The liquid circulation mechanism includes a liquid guide shell 3, which is fixed to the two first fixing rods 108. The middle part of the liquid guide shell 3 is a through hole. The first sliding frame 111 is located in the through hole of the liquid guide shell 3 and slides. The liquid guide shell 3 is divided into two upper and lower chambers. The two chambers of the liquid guide shell 3 are connected by four uniformly distributed conduits 301. The left part of the conduit 301 is embedded in the elastic sleeve 114. The upper chamber of the liquid guide shell 3 is connected to a liquid inlet pipe 302, and the lower chamber of the liquid guide shell 3 is connected to a liquid discharge pipe 303. The liquid inlet pipe 303 is connected to the lower chamber of the liquid guide shell 3. 02 and the discharge pipe 303 both penetrate the first sliding plate 107 and are fixed thereto, the liquid inlet pipe 302 is connected to a water pump electrically connected to the control console 101 through a hose, and when the second sliding plate 113 moves to extrude the pipe to expand, the control console 101 is used to enable the water pump to extract hot water, and the hot water is used to insulate the pipe to facilitate the smooth expansion of the pipe. When the expansion of the pipe is completed, the water pump extracts cold water, and the cold water circulates through the conduit 301 to quickly cool and shape the pipe, thereby improving the quality of pipe processing.
[0034] Reference Figure 7 The swing mechanism includes a servo motor 4 electrically connected to the console 101, the servo motor 4 is fixed to the right side of the fixed plate 1061, the right side of the first sliding plate 107 is fixed with a fixed sleeve 401, the servo motor 4 is located in the fixed sleeve 401, and the output shaft of the servo motor 4 and the fixed sleeve 401 are transmitted through a gear set (a gear is installed on the output shaft of the servo motor 4, and a gear ring is installed on the right end of the fixed sleeve 401, and the gear and the gear ring are meshing).
[0035] When expanding the pipe fittings, first put the pipe fittings to be processed into the upper side of the electric lifting platform 102, then push the pipe fittings into the bracket 104, and then operate the control console 101 according to the size of the pipe fittings, so that the control console 101 starts the third electric push rod 2 to work for a corresponding time, and the third electric push rod 2 drives the sliding ring 201 to move to the right by a specified distance, and the sliding ring 201 moves to the right to squeeze the inclined surfaces of the four second sliding racks 202, and the squeezed four second sliding racks 202 are close to each other and clamp the pipe fittings in the center, so that the pipe fittings are fixed, and this fixing method When clamping and fixing pipes of different specifications, the center lines of the pipes always remain in the same position, which facilitates the present invention to perform expansion operations on pipes of different specifications and improves the applicability of the present invention. In the process of fixing the pipes, since the inner sides of the four second sliding frames 202 are provided with rubber blocks, the friction between the second sliding frames 202 and the pipes is increased, so that the four second sliding frames 202 firmly clamp the pipes. At the same time, the control console 101 controls the electric lifting platform 102 to perform corresponding lifting to ensure that the pipes are in a horizontal state, which is convenient for subsequent operations on the pipes.
[0036] After the pipe is fixed, the control console 101 controls the electric slider 103, which drives the bracket 104 and the electric lifting platform 102 to move, so that the pipe mouth of the pipe is facing the heating unit 115, and then the control console 101 starts the heating unit 115, and the heating unit 115 moves and sleeves on the right part of the pipe to heat the pipe inside it. After the pipe is preheated, the control console 101 controls the heating unit 115 to reset, and then the control console 101 controls the electric slider 103 to move, and the electric slider 103 moves through the connected parts to move the pipe, and makes the pipe mouth of the pipe face the first fixed shell 105, at this time, the center line of the pipe coincides with the arc center line of the first fixed shell 105.
[0037] After the pipe fitting is facing the first fixed shell 105, the first electric push rod 106 is started through the control console 101, and the first electric push rod 106 drives the fixed plate 1061 and the first sliding plate 107 to move leftward in the first fixed shell 105. The movement of the first sliding plate 107 drives the connected parts to move leftward together, so that the elastic sleeve 114 is gradually inserted into the pipe fitting. When the insertion depth of the elastic sleeve 114 is consistent with the expansion length required for the pipe fitting, the control console 101 closes the first electric push rod 106.
[0038] Then, the pipe expansion operation is performed, and the corresponding settings are made on the console 101 according to the diameter of the pipe and the required expansion distance of the pipe, so that the console 101 first starts the second electric push rod 110 to work for a specified time, and the second electric push rod 110 drives the first sliding frame 111 to move to the left by a specified distance, and the first sliding frame 111 moves to the left through two sets of swing rods 112 to make the four second sliding plates 113 move away from each other, and the four second sliding plates 113 move away from each other to extrude the elastic sleeve 114, so that the elastic sleeve 114 expands and extrude the heated part of the pipe, and the pipe expansion operation is performed. Under the tensile deformation and extrusion of the elastic sleeve 114, the pipe is expanded and changed in the circumferential direction to avoid excessive circumferential expansion and contraction changes of the pipe, which causes the pipe to be expanded and cracked and damaged. In addition, due to the setting of the console 101, the extension speed of the second electric push rod 110 gradually slows down, that is, the expansion speed of the elastic sleeve 114 gradually slows down, so that the pipe is prevented from being damaged by rapid expansion, thereby ensuring the quality of pipe processing.
[0039] After the second sliding plate 113 has finished moving, the control console 101 continues to control the second electric push rod 110 to perform a contraction operation, so that the first sliding frame 111 moves a short distance to the right, and the first sliding frame 111 moves right to perform the above-mentioned reverse movement, so that the four second sliding plates 113 are close to each other, that is, the elastic sleeve 114 shrinks and breaks away from the contact inside the pipe. Then the control console 101 starts the servo motor 4, so that the servo motor 4 drives the fixed sleeve 401 to perform intermittent reciprocating rotation through the gear set. The fixed sleeve 401 rotates through the first sliding plate 107 and the two first fixed rods 108 to drive the second fixed shell 109 and the parts connected thereto to rotate together, so that the four second sliding plates 113 and the elastic sleeve 114 rotate within the sleeve to a certain extent. Whenever the elastic sleeve 114 stops rotating (that is, the servo motor 4 stops working), the control console 101 starts the second electric push rod 110 again to extend it, so that it performs the above-mentioned operation again, and the four second sliding plates 113 move away from each other and squeeze different parts of the pipe through the elastic sleeve 114, and squeeze the expanded end of the pipe in multiple directions.
[0040] Repeat the above operation to expand and extrude different parts of the pipe fittings by the four second sliding plates 113. However, during the intermittent reciprocating rotation of the fixed sleeve 401 (i.e., during the operation of the servo motor 4 controlled by the control console 101), the maximum rotation amplitude of the fixed sleeve 401 is 180°. Finally, the four second sliding plates 113 are squeezed in multiple directions by the elastic sleeve 114, so that the inner wall of the expanded part of the pipe fitting is smoother, thereby improving the processing quality of the pipe fitting.
[0041] While the four second sliding plates 113 are moving, the control console 101 simultaneously starts the water pump on the liquid inlet pipe 302, so that the water pump extracts hot water from the liquid storage shell. The hot water passes through the liquid inlet pipe 302 and the upper chamber of the liquid guide shell 3, and then enters the lower chamber of the liquid guide shell 3 through the three conduits 301. Then the hot water returns to the liquid storage shell through the discharge pipe 303. A heating unit 115 is provided in the liquid storage shell to maintain the temperature of the water therein. When the hot water flows in the conduit 301, the temperature of the water is transferred to the sleeve through the conduit 301 and the elastic sleeve 114, so as to maintain the temperature of the pipe during the expansion process and avoid the pipe being set too quickly and affecting the processing quality of the pipe.
[0042] After being squeezed in multiple directions by the four second sliding plates 113, the control console 101 causes the water pump of the liquid inlet pipe 302 to extract cold water from another liquid storage shell, so that the cold water flows through the three conduits 301, wherein the cold water absorbs the heat on the pipe fittings through the conduits 301 and the elastic sleeve 114, and cools and shapes the pipe fittings. After the cold water flows for a period of time, the control console 101 stops the water pump on the liquid inlet pipe 302, and then stops the servo motor 4 and causes the second electric push rod 110 to retract and reset. When the servo motor 4 stops, the solid The fixed sleeve 401 is in the initial state, that is, the two first fixed rods 108 are in a front-to-back symmetrical state, completing the expansion operation of the pipe fitting, and then the first electric push rod 106 is retracted to the initial state through the control console 101, and then the third electric push rod 2 is controlled to retract to the initial state through the control console 101, and under the elastic force of the four first springs 203, the four second sliding frames 202 move away from each other to release the fixation of the pipe fitting, and finally the processed pipe fitting is removed, and the above operation can be repeated when the expansion operation is performed on the remaining pipe fittings.

The fixed block 6 is located between the liquid guide shell 3 and the rotating disk 502, and the two first fixed rods 108 penetrate the fixed block 6, the liquid inlet pipe 302 and the liquid discharge pipe 303 and are slidably connected to the three. One side of the outer wall of the fixed block 6 is divided into a cylindrical side surface and a truncated cone side surface. The inner sides of the two support plates 5051 are fixedly connected to the limiting rod 601, which cooperates with the fixed block 6. The end of the limiting rod 601 close to the fixed block 6 is hemispherical, which is used to reduce the friction between the limiting rod 601 and the fixed block 6. The truncated cone side surface of the fixed block 6 cooperates with the swing rod 112 to ensure that the second sliding plate 113 and the support plate 5051 move synchronously and equidistantly. During the process of the extrusion roller rotating extruding the pipe fitting on the second fixed frame 506, the extrusion force of the extrusion roller on the pipe fitting during the expansion process is always consistent, so that the thickness of the side wall at the expansion of the pipe fitting remains uniform and consistent, thereby improving the quality of the expansion of the pipe fitting.
[0045] In the initial state, under the action of the tension spring 505, the two third sliding plates 504 make the limit rod 601 always fit the side wall of the fixed block 6 through the connected support plate 5051. When the pipe is expanded, the distance between the extrusion rollers on the two second fixed frames 506 is adjusted according to the diameter of the pipe. By twisting the two adjacent rotating sleeves 507 of the same support plate 5051, the two rotating sleeves 507 rotate synchronously to move the adjacent second fixed frames 506, thereby changing the position of the extrusion rollers on the second fixed frames 506. In combination with the scales on the second fixed frames 506, the consistency of the adjustment of the two second fixed frames 506 is maintained, and finally the distance between the two extrusion rollers after adjustment is always slightly larger than the diameter of the processed pipe.
[0046] After the adjustment of the squeezing rollers on the two second fixed frames 506 is completed, the above operation is performed through the control console 101, and the control console 101 starts the driving motor 5 at the same time, wherein during the operation of the second electric push rod 110, the four second sliding plates 113 move away from each other, and the second electric push rod 110 works and drives the fixed block 6 to move to the left through the first sliding frame 111 at the same time, and the fixed block 6 moves leftward first to move the two limiting rods 601 located on the cylindrical side section thereof, at this time the two limiting rods 601 remain stationary, but at this time the first sliding frame 111 drives the four second sliding plates 113 away from each other through the connected swing rod 112, the four second sliding plates 113 move away from each other through the elastic sleeve 114 to squeeze the pipe fitting to deform, and the pipe fitting will be tightly attached to the squeezing rollers on the two second fixed frames 506, and at this time the second fixed frame 506 moves to slightly compress the adjacent second spring 508, and under the elastic force of the second spring 508, the squeezing roller of the second fixed frame 506 slightly squeezes the outer wall of the pipe fitting.
[0047] Then the first sliding frame 111 continues to move to the left, and the first sliding frame 111 drives the fixed block 6 to move synchronously. At this time, the two limiting rods 601 move the truncated cone side section located on the fixed block 6. Under the extrusion of the truncated cone side section on the fixed block 6, the two limiting rods 601 drive the connected support plate 5051 and the second fixed frame 506 to move, and in this process, the four second sliding plates 113 continue to move away from each other. At this time, the moving speed of the second fixed frame 506 is the same as the speed of the second sliding plate 113, so that the extrusion roller on the second fixed frame 506 always contacts the outer wall of the pipe fitting, and the extrusion force of the extrusion roller on the pipe fitting is always kept constant.
[0048] During this process, the driving motor 5 works synchronously. The driving motor 5 drives the rotating disk 502 to rotate through the gear set, and the rotating disk 502 drives the connection connected thereon to rotate together. Even if the extrusion rollers on the two second fixed frames 506 rotate circumferentially to extrude the pipe fittings during the expansion process, the extrusion force of the extrusion rollers on the pipe fittings is always kept constant. Therefore, during the expansion process of the pipe fittings, the thickness of the side wall of the pipe fittings is always kept consistent, and the outer wall of the pipe fittings is kept flat and smooth, thereby improving the quality of pipe fitting processing.
[0049] When the squeezing roller rotates to extrude the pipe, due to the small elastic force of the adjacent second spring 508 on the second fixed frame 506, the squeezing roller on the second fixed frame 506 will not squeeze the pipe to cause obvious deformation. It is mainly used to squeeze the pipe flat. Later, when the four second sliding plates 113 shrink and rotate, the squeezing roller will not squeeze the pipe to cause deformation. The above operation is repeated. After the expansion of the pipe is completed and shaped, the servo motor 4 is controlled to stop to the initial state through the control console 101, and the second electric push rod 110 is controlled to shrink to the initial state. Then, the first electric push rod 106 is controlled to shrink and reset through the control console 101 (wherein the first sliding plate 107 drives the rotating disk 502 to move together through the four limit blocks 501 during the movement). At this time, the driving motor 5 keeps working to make the two squeezing rollers rotate out of contact with the pipe. Then the control console 101 stops the driving motor 5, and the above operation is repeated to remove the processed pipe.
[0050] Example 3: Based on Example 2, refer to Figure 2 and Fig.10, further comprising a supporting mechanism, the supporting mechanism being arranged on the first fixed shell 105, the supporting mechanism being used for centrally supporting the pipe fitting, the supporting mechanism comprising a fourth electric push rod 7 electrically connected to the console 101, the fourth electric push rod 7 being embedded in the connecting block of the first fixed shell 105, the telescopic end of the fourth electric push rod 7 being fixedly connected to a second fixed rod 701, the second fixed rod 701 penetrating the fixed plate 1061 and the first sliding frame 111 and being slidably connected to the two, the left end of the second fixed rod 701 being fixedly connected to a fixed frame 702, the fixed frame 702 being located on the left side of the elastic sleeve 114, the fixed frame 702 being embedded with a The fifth electric push rod 703, the telescopic end of the fifth electric push rod 703 is fixedly connected to the third sliding frame 704, the third sliding frame 704 is provided with four groups of guide grooves equidistantly distributed in the circumferential direction, the guide grooves gradually approach each other from left to right, the fixed frame 702 is slidingly provided with four fourth sliding plates 705 equidistantly distributed in the circumferential direction, the fourth sliding plate 705 is provided with two symmetrically distributed protruding columns, the protruding columns of the fourth sliding plate 705 cooperate with the adjacent guide grooves on the third sliding frame 704, and the inner wall of the pipe fitting is centrally supported by the four third sliding frames 704, so as to further ensure the stability of the pipe fitting during the processing, thereby indirectly improving the quality of the pipe fitting after processing.
[0051] After the heated pipe is moved to face the first fixed shell 105, the fourth electric push rod 7 and the first electric push rod 106 are started to extend synchronously through the control console 101, and the fourth electric push rod 7 drives the fixed frame 702 and the parts connected thereto to move to the left through the second fixed rod 701, while the first electric push rod 106 works to perform the above operation, so that the elastic sleeve 114 moves to the left and enters the pipe.
[0052] When the fourth electric push rod 7 and the first electric push rod 106 finish working and stop, the fifth electric push rod 703 is started through the control console 101 first, and the fifth electric push rod 703 drives the third sliding frame 704 to move rightward. The third sliding frame 704 moves rightward so that the guide groove on it squeezes the protruding columns of the four fourth sliding plates 705. The squeezed four fourth sliding plates 705 move away from each other and contact the inner wall of the pipe fitting, wherein the four fourth sliding plates 705 simultaneously support the pipe fitting in the center, further fixing the pipe fitting to ensure that the pipe fitting remains stable during the edge expansion process, thereby ensuring the quality of the pipe fitting after processing.
[0053] Subsequently, the above operation is repeated through the control console 101 to make the four second sliding plates 113 move accordingly in the pipe. When the expansion of the pipe is completed, the above operation is repeated through the control console 101 to stop and reset the second electric push rod 110 and the servo motor 4. Then, the first electric push rod 106 is started to shrink and reset through the control console 101. After the first electric push rod 106 returns to its initial position, the control console 101 stops driving the motor 5. At this time, the pipe is centrally clamped by the four second sliding frames 202 and centrally supported by the four fourth sliding plates 705 to prevent the pipe from shaking. Subsequently, the fifth electric push rod 703 is firstly retracted and reset through the control console 101, and then the fourth electric push rod 7 is retracted and reset, that is, the above reverse operation is performed. After that, the third electric push rod 2 is reset, and the processed pipe can be removed.
