Description

Technical Field

[0001] The present invention relates to the technical field of crimping, and specifically to a crimping device. Background Art

[0002] Crimping is a fastening method of installing one component on another by external force, and is a connection produced by mechanically pressing the components by means of manual or automatic special crimping tools.

[0003] For the operation of fiberglass sand-filled pipes, fiberglass cloth can be helically wound around the inner lining of the rotating fiberglass sand-filled pipe in the circumferential direction. During the winding process of the fiberglass cloth, resin glue needs to be synchronously applied to the side where the fiberglass cloth contacts the fiberglass sand-filled pipe to ensure that the fiberglass cloth fits more tightly with the fiberglass sand-filled pipe. However, in the existing manufacturing operation process, the fiberglass cloth is directly wound around the fiberglass sand-filled pipe without using any crimping device.

[0004] Therefore, the following problems will occur during the process of winding the gauze on the fiberglass sand-filled pipe: 1. During the winding process of the fiberglass, the fiberglass sand-filled pipe needs to rotate. The existing fiberglass sand-filled pipes generally have a long span. Due to the absence of any external force, the fiberglass sand-filled pipe is subject to a large centrifugal force during rotation, and the middle part of the fiberglass sand-filled pipe is prone to bending deformation, resulting in deformation of the internal structure of the fiberglass sand-filled pipe and affecting the quality of the fiberglass sand-filled pipe.

[0005] 2. During the gluing process of the existing fiberglass cloth, due to reasons such as the coating outflow speed, there may be a problem of uneven distribution of the resin glue on the surface of the fiberglass cloth. After gluing, there may be a problem that the fiberglass cloth does not fit tightly with the fiberglass sand-filled pipe when the fiberglass cloth is wound around the fiberglass sand-filled pipe. Without further external force pressing, the fiberglass cloth at the thinner resin glue part is prone to falling off from the fiberglass sand-filled pipe, affecting the winding effect of the fiberglass cloth on the surface of the fiberglass sand-filled pipe. Summary of the Invention

[0006] The purpose of the present invention is to provide a crimping device. After the fiberglass cloth is wound a certain distance, the fiberglass sand-filled pipe wound with the fiberglass cloth is roll-pressed by a crimping mechanism, so that the fiberglass cloth fits more tightly with the fiberglass sand-filled pipe and the strength of the fiberglass sand-filled pipe is improved.

[0007] The present invention is implemented by adopting the following technical solutions. A crimping device includes a base, and a supporting mechanism and a crimping mechanism are installed on the upper end surface of the base.

[0012] The supporting mechanism can support the rotating glass fiber sand-filled pipe. When the glass fiber cloth is wrapped for a certain distance, the rotating part stops working, and the glass fiber sand-filled pipe wrapped with the glass fiber cloth is rolled by the crimping mechanism, so that the glass fiber cloth and the glass fiber sand-filled pipe are more closely fitted, thereby improving the strength of the glass fiber sand-filled pipe.

[0013] Preferably, a moving block is slidingly provided on the upper end surface of the base, a curved plate is provided on the front end surface of the moving block, an adjusting plate is provided on the upper end surface of the curved plate, and the rear side of the adjusting plate is installed on the moving block through a hinge shaft, and an insertion rod for limiting the adjusting plate is provided on the front end surface of the adjusting plate, and a plurality of insertion holes cooperating with the insertion rod are evenly arranged on the front end surface of the upper end surface of the adjusting plate.

[0020] Preferably, annular grooves for making way for the two front and back sections of the U-shaped frame are respectively opened on the left and right inner side walls of the crimping cylinder. The left and right sides of the extrusion roller are abutted against the inner side wall of the crimping cylinder. The annular grooves can compensate for the lengths of the front and back sections of the U-shaped frame and the shaft heads of the extrusion roller, so that the extrusion roller rolls the fiberglass cloth inside the crimping cylinder more completely, avoiding the resin glue from moving into the gap between the extrusion roller and the inner side wall of the crimping cylinder, and improving the uniformity of the resin glue distribution.

[0024] 4. In the crimping device designed by the present invention, the descending lifting roller can tighten the fiberglass cloth, and thus can play a compensatory role for the fiberglass cloth at the place where the resin glue is thicker, avoiding the fiberglass cloth from wrinkling and keeping the fiberglass cloth in a taut state all the time, improving the fit between the fiberglass cloth and the fiberglass sand-filled pipe, and further improving the strength of the fiberglass sand-filled pipe.

[0044] Refer to Figure 2 , the rotating part 11 includes symmetrically arranged left and right support frames 111, a rotating shaft 112 is installed on the opposite surfaces of the support frames 111 through bearings, a driving circular plate 12 is fixedly installed at one end of the rotating shaft 112 far away from the support frame 111, wherein the right support frame 111 is fixed on the base 1, the left support frame 111 is slidably arranged on the base 1, a fixed protrusion 113 is arranged on the front end surface of the left support frame 111, and a limiting rod 114 for limiting the support frame 111 is arranged on the fixed protrusion 113.

[0045] The driving circular plate 12 is composed of two circular blocks with different diameters. During specific operation, the limiting rod 114 is removed, and the left support frame 111 is taken off. The glass fiber sand-filled pipe 4 for winding the glass fiber cloth is sleeved on the supporting shaft 21. The left limiting frame is reset, and the limiting rod 114 is inserted into the starting position, and the circular block with a smaller diameter on the driving circular plate 12 is clamped inside the glass fiber sand-filled pipe 4. At the same time, the supporting shaft 21 is clamped on the left driving circular plate 12. After the glass fiber sand-filled pipe 4 is placed, the bidirectional air cylinder 1 is started to drive the moving rod 213 to move away from each other. During the movement of the moving rod 213, the supporting rod 22 is driven to rotate around the hinge shaft inside the placing groove 211, and the included angle formed by two adjacent upper and lower supporting rods 22 increases. Further, the supporting rod 22 drives the rubber ball 222 to tightly press against the glass fiber sand-filled pipe 4.

[0046] Refer to Figure 1 、 Figure 7 and Figure 8 As shown in, a moving block 13 is slidably arranged on the upper end surface of the base 1. An arc-shaped plate 14 is arranged on the front end surface of the moving block 13. An adjusting plate 15 is arranged on the upper end surface of the arc-shaped plate 14, and the rear side of the adjusting plate 15 is installed on the moving block 13 through a hinge shaft. A plug rod 16 for limiting the adjusting plate 15 is arranged on the front side of the upper end surface of the adjusting plate 15. A plurality of jacks 17 matching with the plug rod 16 are circumferentially and evenly arranged on the front side of the upper end surface of the arc-shaped plate 14. Two groups of left-right symmetric fixed frames 18 are fixedly installed on the front side of the upper end surface of the adjusting plate 15. A rotating roller 19 is installed between the left and right fixed frames 18 through a bearing. A lifting air cylinder 10 is installed on the upper end surface of the adjusting plate 15 and between the front and rear two groups of fixed frames 18 through a cylinder seat. The upper end surface of the telescopic end of the lifting air cylinder 10 is installed with a U-shaped plate 101. A lifting roller 102 is installed between the two vertical sections of the U-shaped plate 101 through a bearing.

[0047] After the glass fiber sand-filled pipe 4 is supported and limited, the glass fiber cloth is manually wound around the right end of the glass fiber sand-filled pipe 4. The external spraying device is placed between the glass fiber sand-filled pipe 4 and the rear rotating roller 19. Then, the resin glue is sprayed on the upper end surface of the glass fiber cloth through the external spraying device. One end of the glass fiber cloth far from the glass fiber sand-filled pipe 4 passes through the upper side of the rear rotating roller 19, the lower side of the lifting roller 102, the upper side of the front rotating roller 19 and is wound with the external winding mechanism. The upper side of the rear rotating roller 19 is flush with the glass fiber sand-filled pipe 4 to ensure that the resin glue can be horizontally sprayed on the glass fiber cloth and improve the uniformity of the resin glue coating;

[0048] In order to allow the glass fiber cloth to be spirally wound on the glass fiber sand-filled tube 4, the insertion rod 16 is removed, the adjustment plate 15 is rotated to tilt the adjustment plate 15 to a certain angle, and then the insertion rod 16 is inserted into the appropriate insertion hole 17 through the adjustment plate 15.

[0049] See Figure 6 as well as Figure 10 The crimping mechanism 3 includes a crimping base plate 31 slidably arranged on the upper end surface of the base 1 and located below the supporting shaft 21, wherein a crimping cylinder 32 is provided on the upper end of the crimping base plate 31 and is coaxial with the supporting shaft 21. The crimping cylinder 32 is formed by mutually clamping semi-cylinders 321 symmetrically arranged front and back. A movable plate 34 is slidably provided inside the crimping cylinder 32.

[0050] See Figure 9 as well as Figure 10 A profile frame 35 is provided on the rear side of the movable plate 34, and a left-right symmetrical supporting spring rod 36 is installed between the left and right sections of the profile frame 35 and the movable plate 34. An extrusion roller 37 for pressing the glass fiber sand-filled tube 4 is installed between the front and rear sections of the profile frame 35 through a bearing. An adjusting rod 38 extending forward and backward is installed in the middle of the movable plate 34 through a thread. An annular groove 322 for making way for the adjusting rod 38 is provided on the crimping cylinder 32. A toggle rod 39 is installed at the front end of the adjusting rod 38, and the rear end of the adjusting rod 38 rests on the left and right sections of the profile frame 35.

[0051] See Figure 10 The inner wall of the crimping cylinder 32 is provided with left-right symmetrical slide rails 323 , and electric sliders 324 are respectively provided inside the slide rails 323 , and the two electric sliders 324 are fixedly connected to the movable plate 34 .

[0052] See Figure 6 as well as Figure 7 A linkage plate 311 is installed between the crimping base plate 31 and the moving block 13. A rectangular groove is provided on the front side of the upper end face of the base 1. A screw 103 is installed in the rectangular groove through a bearing, and the screw 103 and the arc plate 14 are screwed together. The rotating shaft 112 and the screw 103 are connected to each other through a belt drive.

[0053] See Figure 6 A 匚-shaped connecting frame 312 that is symmetrical front and back and opens upward is arranged between the crimping cylinder 32 and the crimping base plate 31. The two vertical sections of the 匚-shaped connecting frame 312 are respectively located on the left and right sides of the annular groove 322 and are fixedly connected to the crimping cylinder 32. The horizontal section of the 匚-shaped connecting frame 312 is slidably arranged on the upper end surface of the crimping base plate 31.

[0054] On the upper end surface of the crimping base plate 31 and between the two U-shaped connecting frames 312, a double-acting cylinder two (not shown in the figure) is installed through a cylinder seat. The front and rear telescopic ends of the double-acting cylinder two are respectively fixedly connected to the horizontal sections of the front and rear U-shaped connecting frames 312. On the right side of the upper end surface of the base 1, a driving motor is installed through a motor seat. The output shaft of the driving motor is connected to the left rotating shaft 112 through a belt drive. During specific operation, the double-acting cylinder two is started to drive the semi-cylindrical tube 321 to move away through the U-shaped connecting frame 312. At this time, the crimping cylinder 32 opens.

[0055] The driving motor is started to drive the left rotating shaft 112 to rotate through a belt drive. During the rotation of the left rotating shaft 112, the fiberglass sand-filled pipe 4 is driven to rotate through the cooperation of the driving circular plate 12 and the supporting shaft 21. During the rotation of the left rotating shaft 112, the arc-shaped plate 14 is synchronously driven to move from right to left through a belt drive. During the movement of the arc-shaped plate 14, the crimping base plate 31 is synchronously driven to move through the linkage plate 311. Thus, the fiberglass cloth can be spirally wound on the surface of the fiberglass sand-filled pipe 4 during the rotation of the fiberglass sand-filled pipe 4.

[0056] When the fiberglass cloth is wound a certain distance, the rotating shaft 112 stops rotating. At this time, the semi-cylindrical tube 321 synchronously moves to the front and rear sides of the fiberglass sand-filled pipe 4. The double-acting cylinder two is started again to drive the semi-cylindrical tube 321 to move towards each other through the U-shaped connecting frame 312. The semi-cylindrical tubes 321 are mutually fitted. The left and right side walls of the semi-cylindrical tubes 321 clamp the fiberglass sand-filled pipe 4 wound with the fiberglass cloth. At this time, the toggle lever 39 is rotated to drive the adjusting rod 38 to rotate. During the rotation of the adjusting rod 38, it moves backward synchronously. At this time, the rear end of the adjusting rod 38 drives the U-shaped frame 35 to move backward. During the movement of the U-shaped frame 35, the pressing roller 37 is brought to lean against the fiberglass cloth on the fiberglass sand-filled pipe 4, and the supporting spring rod 36 is stretched.

[0057] At this time, the electric slider 324 is started to drive the moving plate 34 to move circumferentially around the fiberglass sand-filled pipe 4. During the movement of the moving plate 34, the pressing roller 37 is driven to press the fiberglass cloth on the fiberglass sand-filled pipe 4 through the cooperation of the supporting spring rod 36 and the U-shaped frame 35. Thus, during the rolling process of the pressing roller 37, the resin glue on the fiberglass cloth can be evenly distributed, avoiding the situation that the fiberglass cloth is easily detached from the fiberglass sand-filled pipe 4 at the place where the resin glue is thinner, making the fiberglass cloth fit more closely with the fiberglass sand-filled pipe 4, and improving the winding effect of the fiberglass cloth on the surface of the fiberglass sand-filled pipe 4.

[0058] Refer to Figure 9, annular grooves 325 for making way for the two front and rear segments of the C-shaped frame 35 are provided on the left and right inner side walls of the crimping cylinder 32, and the left and right sides of the extrusion roller 37 are abutted against the inner side wall of the crimping cylinder 32. The annular grooves 325 can compensate for the lengths of the front and rear segments of the C-shaped frame 35 and the shaft heads of the extrusion roller 37, so that the extrusion roller 37 can roll the fiberglass cloth inside the crimping cylinder 32 more completely, avoid the resin glue from moving into the gap between the extrusion roller 37 and the inner side wall of the crimping cylinder 32, and improve the uniformity of the resin glue distribution.

[0059] The left and right sides of the crimping cylinder 32 can prevent the resin glue on the fiberglass cloth of the fiberglass sand-filled pipe 4 from overflowing from the left and right sides during the rolling process, ensure the uniform thickness of the resin glue between the fiberglass sand-filled pipe 4 and the fiberglass cloth, avoid the resin glue from being too thin, improve the adhesion between the fiberglass cloth and the fiberglass sand-filled pipe 4. After the rolling is completed, start the double-acting cylinder two to drive the semi-cylindrical barrel 321 to move away through the C-shaped connecting frame 312, and the crimping cylinder 32 opens;

[0060] Start the lifting cylinder 10 to drive the lifting roller 102 to move downward through the C-shaped plate 101. At this time, the downward movement of the lifting roller 102 tightens the fiberglass cloth, compensates for the fiberglass cloth at the place where the resin glue is thicker, avoids the fiberglass cloth from wrinkling and keeps the fiberglass cloth in a taut state all the time, improves the adhesion between the fiberglass cloth and the fiberglass sand-filled pipe 4, and further improves the strength of the fiberglass sand-filled pipe 4.

[0061] After the above steps are completed, repeating the above actions can perform the crimping treatment on the next section of fiberglass cloth.

[0062] During the crimping process of the fiberglass sand-filled pipe using the above crimping device, the following steps are included: First step, placement treatment: Remove the limit rod 114 and remove the left support frame 111. Sleeve the fiberglass sand-filled pipe 4 to be wound with fiberglass cloth on the supporting shaft 21. Reset the left limit frame and insert the limit rod 114 into the starting position, and make the smaller-diameter round block on the driving circular plate 12 be clamped inside the fiberglass sand-filled pipe 4, and at the same time make the supporting shaft 21 be clamped on the left driving circular plate 12.

[0063] Second step, support treatment: After the placement of the fiberglass sand-filled pipe 4 is completed, start the double-acting cylinder one 212 to drive the moving rod 213 to move away. During the movement of the moving rod 213, it drives the support rod 22 to rotate around the hinge shaft inside the placement groove 211, and the included angle formed by the upper and lower adjacent support rods 22 increases. Then the support rod 22 drives the rubber ball 222 to tightly press the fiberglass sand-filled pipe 4.

[0064] The third step is gluing: after the support and limiting of the glass fiber sand-filled tube 4 is completed, the glass fiber cloth is manually wound around the right end of the glass fiber sand-filled tube 4, and the external spraying equipment is placed between the glass fiber sand-filled tube 4 and the rotating roller 19 at the rear side, and then the resin glue is sprayed on the upper end surface of the glass fiber cloth by the external spraying equipment. The glass fiber cloth is away from the end of the glass fiber sand-filled tube 4 and passes through the upper side of the rotating roller 19 at the rear side, the lower side of the lifting roller 102, and the upper side of the rotating roller 19 at the front side to be wound with the external winding mechanism.

[0065] Step 4, winding processing: start the two-way air cylinder 2 to drive the semi-cylinder 321 to move away from each other through the 匚-shaped connecting frame 312. At this time, the crimping cylinder 32 is opened, and the driving motor is started to drive the rotating shaft 112 on the left to rotate through the belt transmission. During the rotation of the rotating shaft 112 on the left, the driving circular plate 12 and the supporting shaft 21 cooperate with each other to drive the glass fiber sand-filled tube 4 to rotate. During the rotation of the rotating shaft 112 on the left, the curved plate 14 is synchronously driven to move from right to left through the belt transmission. During the movement of the curved plate 14, the crimping base plate 31 is driven to move synchronously through the linkage plate 311, and then the glass fiber sand-filled tube 4 during the rotation process can spirally wrap the glass fiber cloth on its surface.

[0066] Step 4: Crimping: When the glass fiber cloth is wound for a certain distance, the rotating shaft 112 stops rotating. At this time, the semi-cylinder 321 moves synchronously to the front and rear sides of the glass fiber sand-filled tube 4. The two-way cylinder 2 is started again to drive the semi-cylinder 321 to move toward each other through the 匚-shaped connecting frame 312. The semi-cylinder 321 fits each other. The left and right side walls of the semi-cylinder 321 clamp the glass fiber sand-filled tube 4 after the glass fiber cloth is wound. At this time, the toggle rod 39 is rotated to drive the adjusting rod 38 to rotate. The adjusting rod 38 moves backward synchronously during the rotation process. At this time, the adjusting rod The rear end of 38 drives the profile frame 35 to move backward. During the movement of the profile frame 35, it drives the squeezing roller 37 to stick to the glass fiber cloth on the glass fiber sand-filled tube 4. The electric slider 324 is started to drive the movable plate 34 to move circumferentially around the glass fiber sand-filled tube 4. During the movement of the movable plate 34, the supporting spring rod 36 and the profile frame 35 cooperate with each other to drive the squeezing roller 37 to squeeze the glass fiber cloth on the glass fiber sand-filled tube 4, so that the resin glue on the glass fiber cloth can be evenly distributed during the rolling process of the squeezing roller 37.

[0067] Step 4: Compensation: Start the lifting cylinder 10 to drive the lifting roller 102 downward through the molded plate 101. At this time, the lifting roller 102 moves downward to tighten the glass fiber cloth, compensating for the glass fiber cloth where the resin glue is thicker.
