Description

Technical Field

[0001] The invention relates to the technical field of pipeline forming molds, and in particular to a demoulding structure for vertically forming a glass fiber reinforced plastic composite pipe. Background Art

[0002] The structure of the FRP composite pipe consists of four parts: lining, filter layer, structural layer and protective layer. The main raw materials and auxiliary materials used in the production of FRP composite pipes are resin, surface felt, glass fiber and quartz sand. The processing process is: first, evenly apply resin to the surface felt on the core mold, wait for it to gel, then evenly wrap the glass fiber, and finally evenly apply resin again. After it is shaped, the processing and production of the FRP composite pipe is completed.

[0003] When the existing FRP composite pipe is demolded after processing, lubricant is often added between the FRP composite pipe and the core mold, and then the FRP composite pipe is slowly pulled out manually. During this process, the inner wall of the FRP composite pipe is still tightly attached to the core mold after it is shaped, which makes it inconvenient to demold the FRP composite pipe. The demolding process is time-consuming and labor-intensive, and the lubricant is not easy to fill the space between the FRP composite pipe and the core mold, resulting in low demolding efficiency.

[0032] Example 1: A vertical forming glass fiber reinforced plastic composite pipe demoulding structure, as shown in the attached Figure 1 -Attached Figure 5As shown, it includes a support frame 1, a control panel 101 is installed on the left side of the front side of the support frame 1, the support frame 1 is F-shaped, the support frame 1 is fixedly connected to a first drive motor 102, and the support frame 1 is rotatably provided with a rotating sleeve 103, the middle part of the rotating sleeve 103 is set to an elastic high-temperature resistant material, and the rotating sleeve 103 and the output shaft of the first drive motor 102 are driven by a gear set (the output shaft of the first drive motor 102 is fixedly connected to a gear, and the left end of the rotating sleeve 103 is fixedly connected to a gear ring, and the gear and the gear ring are meshed), the left part of the support frame 1 is rotatably connected to a fixed column 104, the fixed column 104 is located in the rotating sleeve 103, and the right end of the fixed column 104 The left part of the support frame 1 is fixed with a rotating frame 105 fixed with a rotating sleeve 103, and the left part of the support frame 1 is provided with an electric slider 106 through a slide rail. The upper surface of the electric slider 106 is fixed with a first sliding plate 107. The fixed column 104 penetrates the first sliding plate 107 and is slidably connected with it. The first sliding plate 107 is fixed with a sliding sleeve 108 that slides on the fixed column 104. The right part of the sliding sleeve 108 is rotatably provided with a first sliding column 109. The first sliding column 109 is slidably connected to the fixed column 104 and the rotating sleeve 103, and the inner wall and left side wall of the first sliding column 109 are provided with sealing rings, which are used to strengthen its connection with the fixed column 104. The sealing between the first sliding column 109 and the rotating sleeve 103 is improved. The right side of the first sliding column 109 is fixedly connected with a first supporting plate 110 distributed equidistantly in the circumference. The right part of the fixed column 104 is slidably provided with a second sliding column 111. The inner wall and the right side wall of the second sliding column 111 are provided with a sealing ring. The sealing ring is used to enhance the sealing between it and the fixed column 104 and the rotating sleeve 103. The left side of the second sliding column 111 is fixedly connected with a second supporting plate 112 distributed equidistantly in the circumference. The first supporting plates 110 distributed equidistantly in the circumference and the second supporting plates 112 distributed equidistantly in the circumference cooperate to form a circular ring with a smooth outer surface, and the first supporting plate 110 and the second supporting plate 112 are provided. 2 are both configured as inclined surfaces, the inclined surface of the first support plate 110 cooperates with the corresponding inclined surface of the second support plate 112, the first sliding plate 107 is provided with a pushing mechanism for synchronously moving the first sliding column 109 and the second sliding column 111, the left side of the first sliding column 109 and the right side of the second sliding column 111 are fixedly connected with a fixed block 301, the fixed column 104 is provided with two sets of centrosymmetrical torsional mechanisms, the torsional mechanisms are used to rotate the first sliding column 109 or the second sliding column 111, the fixed block 301 cooperates with the corresponding torsional mechanisms, and the first drive motor 102 and the electric slider 106 are both electrically connected to the control panel 101.

[0033] As attached Figure 2 and attached Figure 4 -Attached Figure 6As shown, the pushing mechanism includes two first push rods 2 that are symmetrical in upper and lower directions, and the two first push rods 2 are both fixed to the left side of the first sliding plate 107. The support frame 1 is embedded with two first fixed shells 201 that are symmetrical in upper and lower directions, and the first push rod 2 is located in the corresponding first fixed shell 201 and slides. A connecting pipe 2011 is connected between the left sides of the two first fixed shells 201, and a liquid guide tube 202 is rotatably provided in the middle part of the right side of the connecting tube 2011. The liquid guide tube 202 is embedded in the fixed column 104, and a conduit 203 that is connected to the liquid guide tube 202 is embedded in the right part of the fixed column 104. The fixed column 104 is fixed with two second fixed shells 204 that are symmetrical in upper and lower directions, and the two second fixed shells 204 are both connected to the conduit 203. A second push rod 205 is slidably provided in the second fixed shell 204, and the second sliding column 111 is provided with symmetrically distributed limiting slide grooves, which are arc-shaped. The second push rod 205 is located in the second The sliding column 111 slides in the corresponding limiting groove on the first fixed shell 201 and the second fixed shell 204 is filled with liquid, and the volume of the first fixed shell 201 is the same as that of the second fixed shell 204. During the movement of the electric slider 106, the first sliding column 109 and the second sliding column 111 are synchronously moved away from each other through the connected parts. Since the first sliding column 109 and the second sliding column 111 are sealed with the fixed column 104 and the rotating sleeve 103, the gas pressure in the fixed column 104, the rotating sleeve 103, the first sliding column 109 and the second sliding column 111 is reduced. At the same time, the first support plate 110 and the second support plate 112 move to make the gas contact with the rotating sleeve 103. Under the action of the gas pressure, the rotating sleeve 103 is concave inward and separated from the formed glass fiber reinforced plastic composite pipe, thereby reducing the friction between the rotating sleeve 103 and the glass fiber reinforced plastic composite pipe and improving the demoulding efficiency.

[0034] As attached Figure 4 and attached Figure 7As shown, the torsion mechanism includes a fixing frame 3, which is fixed to the upper side of the fixing column 104, and the fixing frame 3 is arc-shaped. The fixing frame 3 is slidably connected to the corresponding fixing block 301, and the fixing block 301 is provided with a convex column. A first spring 302 is installed between the fixing block 301 and the corresponding fixing frame 3, and the first spring 302 is sleeved on the corresponding fixing frame 3. The upper side of the inner part of the rotating sleeve 103 is fixed with a limit block 303, and the limit block 303 is provided with an inclined surface that cooperates with the convex column on the corresponding fixing block 301, and is away from the first sliding column 109 and the second sliding column 111. During the rotation process, the fixed blocks 301 connected thereto are brought into contact with the corresponding limit blocks 303. Under the limiting action of the inclined surfaces on the limit blocks 303, the two fixed blocks 301 respectively drive the first sliding post 109 and the second sliding post 111 to rotate relative to each other. The rotation of the first sliding post 109 and the second sliding post 111 causes the first support plate 110 and the second support plate 112 to rotate, thereby changing the deformation position of the rotating sleeve 103, thereby increasing the separation area between the rotating sleeve 103 and the glass fiber reinforced plastic composite pipe, and further reducing the friction between the rotating sleeve 103 and the glass fiber reinforced plastic composite pipe.

[0035] During the production of the FRP composite pipe, a film is wrapped around the side wall of the rotating sleeve 103 in advance to facilitate the subsequent demoulding of the FRP composite pipe. Then, resin is evenly applied to the side wall of the rotating sleeve 103 and surface felt is added to the resin. Then, one end of the glass fiber on the existing winding device is fixed to the rotating sleeve 103. At this time, the glass fiber is located near the left end of the first sliding column 109. Then, the first drive motor 102 is started through the control panel 101. The first drive motor 102 drives the rotating sleeve 103 to rotate through the gear set. The rotation of the rotating sleeve 103 drives the fixed column 104 and the parts connected thereto to rotate together through the rotating frame 105. During the rotation of the rotating sleeve 103, the existing winding device performs corresponding left and right reciprocating movements, so that the glass fiber is wound around the side wall of the rotating sleeve 103 layer by layer, wherein the glass fiber is always slightly located between the first sliding column 109 and the second sliding column 111.

[0036] When the film is wrapped in a limited manner, the first drive motor 102 is turned off through the control panel 101 to stop the rotation of the rotating sleeve 103. The glass fiber is then cut and the resin is evenly applied to its outside again to complete the production and processing of the FRP composite pipe. The FRP composite pipe is then cooled and shaped.

[0037] After the glass fiber reinforced plastic composite pipe is shaped, the electric slider 106 is started through the control panel 101. The electric slider 106 drives the first sliding plate 107 to move to the left. The first sliding plate 107 drives the first sliding column 109 and the first support plate 110 evenly distributed thereon to move to the left through the sliding sleeve 108. During this process, the first sliding plate 107 simultaneously drives the two first push rods 2 to move to the left. The first push rod 2 moves to the left to squeeze the liquid in the two first fixed shells 201. The liquid in the two first fixed shells 201 enters the two second fixed shells 204 through the connecting pipe 2011, the liquid guide tube 202 and the catheter 203. The liquid in the second fixed shell 204 squeezes the adjacent second push rod 205 to move, and the second push rod 205 pushes the second sliding column 111 and the second support plate 112 connected thereto to move to the right. Since the volume of the first fixed shell 201 is the same as that of the second fixed shell 204, the moving speed of the first sliding column 109 is the same as the moving speed of the second sliding column 111.

[0038] In the process of the first sliding column 109 and the second sliding column 111 moving away from each other, since sealing rings are installed on the first sliding column 109 and the second sliding column 111, the first sliding column 109 and the second sliding column 111 respectively maintain a sealed fit with the fixed column 104 and the rotating sleeve 103. In the above working process, the volume of the chamber formed by the first sliding column 109, the second sliding column 111, the fixed column 104 and the rotating sleeve 103 becomes larger, thereby forming a negative pressure in the chamber. Under the action of the negative pressure, the middle part of the rotating sleeve 103 is adsorbed through the gap between the first support plate 110 and the second support plate 112. Since the middle part of the rotating sleeve 103 is made of elastic material, the rotating sleeve 103 at the adsorbed position will be concave inward, and the inward concavity of the rotating sleeve 103 will be separated from the glass fiber reinforced plastic composite pipe, which is convenient for the subsequent removal of the glass fiber reinforced plastic composite pipe.

[0039] When the protrusion of the fixed block 301 moves close to the corresponding limit block 303, the inclined surface of the first support plate 110 moves close to the inclined surface of the second support plate 112. The subsequent electric slider 106 continues to work, and the first sliding post 109 and the second sliding post 111 continue to move, so that the inclined surface on the limit block 303 squeezes the protrusion of the adjacent fixed block 301. Since the two limit blocks 303 are centrally symmetrical, the two fixed blocks 301 rotate relative to each other at this time, that is, the first sliding post 109 drives the first support plate 110 on it to rotate together, and the second sliding post 111 drives the second support plate 112 on it to rotate together (at this time, the rotation direction of the second sliding post 111 is opposite to the rotation direction of the first sliding post 109). As the first support plate 110 and the second support plate 112 rotate, the adsorption position of the gas in the chamber on the rotating sleeve 103 is changed, so that the rotating sleeve 103 is separated from the glass fiber reinforced plastic composite pipe more thoroughly.

[0040] When the electric slider 106 moves to the left limit position and stops working, the first support plate 110 rotates so that its upper inclined surface fits into the corresponding second support plate 112, and then the lubricant is filled into the deformation groove of the rotating sleeve 103. The lubricant flows and fills the space between the rotating sleeve 103 and the FRP composite pipe, sufficiently reducing the friction between the rotating sleeve 103 and the FRP composite pipe. Then, the right end of the FRP composite pipe is clamped by the existing clamp, and then the existing traction device is used to slowly pull the FRP composite pipe to the right to complete the processing and demolding of the FRP composite pipe.

[0041] After the FRP composite pipe is demoulded, the electric slider 106 is started to move in the reverse direction through the control panel 101, so that it performs the above-mentioned reverse movement and reset. The inclined surfaces of the first support plate 110 and the second support plate 112 facilitate the above-mentioned reverse rotation and reset of the first sliding column 109 and the second sliding column 111, and at the same time facilitate the first support plate 110 to re-coordinate with the corresponding second support plate 112 for reset.

[0042] Example 2: Based on Example 1, as shown in the attached Figure 8 -Attached Figure 10 As shown, it also includes an extrusion demoulding mechanism for reducing damage to the glass fiber reinforced plastic composite pipe. The extrusion demoulding mechanism is arranged on the support frame 1, and the support frame 1 is slidingly provided with a slide groove. The extrusion demoulding mechanism includes two sliding blocks 4 symmetrical in front and back. The two sliding blocks 4 are slidably arranged in the slide groove of the support frame 1. The front part of the sliding block 4 is provided with a slide groove, and the right part of the sliding block 4 is provided with a chamber. A first sliding frame 401 is vertically slidably arranged in the slide groove of the sliding block 4, and a second driving motor 402 is fixedly connected to the right side of the first sliding frame 401. The output shaft of the second driving motor 402 is fixedly connected to a first gear 403. The support frame 1 is fixed with two first racks 404 symmetrical in front and back. The first gear 403 is meshed with the corresponding first rack 404. A second sliding frame 405 is vertically slidably provided in the chamber of the sliding block 4. The second sliding frame 405 is approximately in the shape of a 7, and a rotating device 405 is provided in the second sliding frame 405. A rotating shaft 406 is provided, which is fixedly connected to the output shaft of the corresponding second drive motor 402. A wedge block 407 for limiting the corresponding second sliding frame 405 is slidably provided in the chamber of the sliding block 4. A second spring 408 is installed between the wedge block 407 and the corresponding sliding block 4. A pull rope 409 is fixedly connected to the upper surface of the second sliding frame 405. The pull rope 409 penetrates the corresponding sliding block 4 and is slidably connected thereto. A second sliding plate 410 is slidably provided in the sliding groove of the support frame 1, and the second sliding plate 410 slides on the outside of the rotating sleeve 103. The left end of the pull rope 409 is fixedly connected to the second sliding plate 410. Both rotating shafts 406 are provided with a deceleration component, which is used to slow down the movement of the sliding block 4 and increase its traction force. The second drive motor 402 works to make the second sliding plate 410 push the glass fiber reinforced plastic composite pipe to the right with a constant pressure.

[0043] As attached Figure 11 As shown, the deceleration assembly includes a second gear 5, which is fixed to the corresponding rotating shaft 406, and the second sliding frame 405 is rotatably provided with a third gear 501 meshing with the corresponding second gear 5, and the support frame 1 is fixed with a second rack 502, and the second rack 502 cooperates with the corresponding third gear 501, and the transmission ratio of the third gear 501 to the adjacent second rack 502 is smaller than the transmission ratio of the first gear 403 to the adjacent first rack 404. In the process of the second sliding plate 410 pushing the FRP composite pipe to the right, if the movement resistance of the FRP composite pipe increases, the first gear 403 is disengaged from the adjacent first rack 404, and at the same time, the third gear 501 is meshed with the adjacent second rack 502. Due to the smaller transmission ratio, the extrusion force of the second sliding plate 410 on the FRP composite pipe becomes larger. When the movement resistance of the FRP composite pipe is restored, the extrusion force on the FRP composite pipe is restored to be constant again, thereby reducing damage to the FRP composite pipe while ensuring the demoulding efficiency.

[0044] In the initial state, under the elastic force of the second spring 408, the wedge block 407 squeezes and limits the second sliding frame 405, so that the first gear 403 is engaged with the adjacent first rack 404, and the third gear 501 is disengaged from the adjacent second rack 502. Then, after the electric slider 106 has finished working, the two second drive motors 402 are started to work synchronously through the control panel 101. The two second drive motors 402 drive the adjacent first gears 403 to rotate. At the same time, the first gear 403 moves on the adjacent first rack 404, that is, the two sliding blocks 4 move to the right. The movement of the sliding block 4 drives the second sliding plate 410 to move to the right through the pull rope 409. The second sliding plate 410 moves to the right and squeezes the FRP composite pipe. Due to the deformation of the rotating sleeve 103, the contact area between it and the FRP composite pipe is reduced, thereby reducing the friction between the FRP composite pipe and the rotating sleeve 103, thereby reducing the damage to the FRP composite pipe during the demoulding process.

[0045] During the process of the second sliding plate 410 pushing the FRP composite pipe to move to the right, when the movement resistance of the FRP composite pipe suddenly increases, the two second drive motors 402 continue to work, causing the two sliding blocks 4 to continue to move to the right. However, at this time, due to the increased movement resistance of the FRP composite pipe, the pulling force of the pull rope 409 on the adjacent second sliding frame 405 increases, and the pull rope 409 pulls the adjacent second sliding frame 405 and the parts connected thereto to move upward together, and the second sliding frame 405 moves upward to squeeze the adjacent wedge block 407 to move to the left, wherein the second sliding frame 405 moves upward. , so that the third gear 501 is engaged with the adjacent second rack 502, and at this time the second drive motor 402 rotates to drive the second sliding frame 405 to rotate, and the second sliding frame 405 drives the third gear 501 to rotate through the second gear 5, and continues to move the sliding block 4 to the right. Since the transmission ratio of the third gear 501 and the adjacent second rack 502 is smaller than the transmission ratio of the first gear 403 and the adjacent first rack 404, the movement speed of the sliding block 4 is slowed down, but at this time the driving force of the sliding block 4 to drive the second sliding plate 410 to move becomes larger, thereby ensuring the demoulding efficiency of the glass fiber reinforced plastic composite pipe.

[0046] When the moving speed of the FRP composite pipe is restored, the second sliding frame 405 is restored to its initial state under the elastic force of the second spring 408, that is, the first gear 403 is restored to the meshing with the adjacent first rack 404, thereby reducing the extrusion of the FRP composite pipe, and reducing the damage to the FRP composite pipe while ensuring the demoulding efficiency of the FRP composite pipe. When the second drive motor 402 moves to the right limit and stops the process, the demoulding of the FRP composite pipe is completed, and then the second drive motor 402 is started through the control panel 101 to work in reverse and reset.

Any technician familiar with this technical field can easily think of changes or replacements within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
