Description

Technical Field

[0001] The invention relates to the technical field of liner production and processing, and in particular to a bending device for the production and processing of thermoplastic formed liner pipes. Background Art

[0002] Liner pipe generally refers to plastic-lined steel pipe. Plastic-lined steel pipe is based on galvanized seamless steel pipe and welded steel pipe. After the weld ribs are removed from the inner wall, food-grade polyethylene pipe of the same diameter as the galvanized pipe is lined. The thickness of the polyethylene lining must comply with the HG / T 20538-2016 standard. It is finally formed after being pressurized and heated for a certain period of time. It is an upgraded product of traditional galvanized pipe and an ideal pipeline for conveying media such as acid, alkali, salt, and corrosive gases. Hot bending is the process of bending the pipe fittings after heating them to a fixed bending temperature of the pipe fittings. Thermoplastic pipe is a member of the polyolefin series and one of the lightest known plastics. It has excellent chemical resistance to many acids, alkalis and organic solvents. When producing thermoplastic pipes, hot bending forming processing equipment must be used to hot bend the pipes.

[0003] Announcement No. CN 214111451 U discloses a hot bending forming processing device for thermoplastic plastic pipes. By setting a cooling mechanism, the cold air blower is started after the processing is completed. The cold air flow generated when the cold air blower is running can enter the cavity through the connecting pipe and be sprayed out by multiple spray holes. The cold air flow sprayed by the multiple spray holes can be blown to the surface of the pipe after the hot bending process, thereby having a cooling effect on the pipe. There is no need to disassemble the pipe from the hot bending device and then transport it to the cooling equipment for cooling, which improves the working efficiency of the device and can also prevent the staff from being scalded by the high-temperature pipe when taking and placing the finished pipe, thereby improving the safety of the device. By setting an air guide cover, the staff can rotate the air guide cover by the handle to rotate the air guide cover to the top of the mounting plate, and one end of the air guide cover is just placed on the two support blocks. Under the action of the air guide cover, the cold air flow can be blown to the pipe more concentratedly, thereby improving the cooling effect. However, the patent still has the following problems in actual use:

[0004] Although the hot bending forming processing device of the thermoplastic plastic pipe can realize the cooling function of the pipe, it is not convenient to fix pipes of different diameters, and it is not possible to recycle heat energy, resulting in a waste of heat energy. The pipe is cooled by the cold air flow generated by the operation of the cold air blower. Although it can realize rapid cooling of the pipe, since the temperature of the pipe is high and the temperature of the cold air is low, it is easy to cause the pipe to break due to thermal expansion and contraction, which is not conducive to the bending of the pipe.

[0005] Therefore, a bending device for the production and processing of thermoplastic formed liner pipes is proposed to solve the above-mentioned problems. Summary of the invention

[0006] The object of the present invention is to provide a bending device for the production and processing of thermoplastic formed liner pipes, so as to solve the problem that the hot bending forming processing device of the thermoplastic plastic pipe proposed in the above background technology can realize the cooling function of the pipe, but it is not convenient to fix the pipes of different diameters, and it is not possible to recycle the heat energy, resulting in the waste of heat energy.

The specific contents are as follows:

[0022] 1. By setting up the thermoplastic mechanism, not only can the lifting motor be used to drive the first sprocket transmission assembly and the lifting bidirectional threaded rod to rotate, so that the lifting threaded sleeve can drive the lifting rotating rod to rotate while moving relatively on the lifting bidirectional threaded rod, thereby realizing the lifting and lowering of the lifting plate, and moving the top bending roller to the top of the liner body.

[0041] The fixing mechanism 2 includes a first fixing support 201 and a second fixing support 202. The first fixing support 201 is fixedly installed at the bottom of the lifting plate 112, and the second fixing support 202 is fixedly installed at the top of the workbench 101. One side of the first fixing support 201 is rotatably connected with an adjusting knob 203. The end of the adjusting knob 203 is fixedly connected with an adjusting bidirectional threaded rod 204. The outer side of the adjusting bidirectional threaded rod 204 is threadedly connected with an adjusting threaded sleeve 205. The bottom of the two adjusting threaded sleeves 205 is fixedly installed with a top rotating support 206. The bottom of the top rotating support 206 is rotatably connected to a fixed rotating rod 207, and the middle part of the two fixed rotating rods 207 is rotatably connected to an adjusting rotating shaft 208. The adjusting knob 203 is used to drive the adjusting bidirectional threaded rod 204 to rotate, so that the adjusting threaded sleeve 205 can drive the fixed rotating rod 207 to rotate around the adjusting rotating shaft 208 while the adjusting bidirectional threaded rod 204 rotates relative to each other. The top rotating support 206 can change the rotation angle and height of the fixed rotating rod 207, so that the liner body 137 of different diameters can be initially fixed.

[0042] The bottom support rod 209 is fixedly installed at the inner center position of the second fixed support 202, and a support spring 210 is fixedly installed in the middle of the bottom support rod 209. The two ends of the support spring 210 are symmetrically installed with a clamping sliding sleeve 211. The top and bottom of the clamping sliding sleeve 211 are rotatably connected with a clamping rotating rod 212. The ends of the two clamping rotating rods 212 are rotatably connected with a rotating plate 213. The outer side of the rotating plate 213 is fixedly installed with a clamping plate 214. The top of the top clamping plate 214 is fixedly installed with a clamping spring 215. The top of the spring 215 is fixedly connected to a bottom support seat 216, and the two sides of the bottom support seat 216 are symmetrically rotatably connected to the first clamping arm 217, and the top side of the pressing sliding sleeve 211 is fixedly installed with a first rotating support 218, and the top of the first rotating support 218 is rotatably connected to a clamping rotating rod 219, and the top of the clamping rotating rod 219 is rotatably connected to a second rotating support 220, and the top of the second rotating support 220 is fixedly connected to a second clamping arm 221, and the two sides of the second clamping arm 221 are symmetrically installed with clamping slide rails 222. The second clamping arm 221 is slidably connected to the first clamping arm 217 through the clamping slide rail 222. When the liner body 137 is placed on the bottom support seat 216, the bottom support seat 216 squeezes the compression spring 215 through the gravity of the liner body 137 itself, thereby realizing the rotation of the first clamping arm 217, and the liner body 137 can be initially clamped and fixed. When the lifting plate 112 drives the first fixed support 201 and the fixed rotating rod 207 to move downward, the liner body 137 can be squeezed to make the liner body 137 continue to move downward. The clamping rotating rod 212 is driven to rotate relative to each other while stretching the supporting spring 210, so that the clamping rotating rod 212 drives the first rotating support 218 and the clamping rotating rod 219 to move horizontally. Under the limiting action of the first clamping arm 217, the second rotating support 220 drives the second clamping arm 221 to slide inside the first clamping arm 217, and the bottom of the liner body 137 is clamped for the second time by the first clamping arm 217 and the second clamping arm 221, thereby improving the clamping stability of the liner body 137 and facilitating the bending of the liner body 137.

[0043] Working principle: Before using this thermoplastic forming liner production and processing bending equipment, it is necessary to check the overall condition of the device to ensure that it can work normally. Figure 1 - Fig.12As shown, first, the liner body 137 is placed on the bottom support seat 216 on the top of the workbench 101, and the bottom support seat 216 is squeezed and compressed by the gravity of the liner body 137 itself to realize the rotation of the first clamping arm 217, so that the liner body 137 can be initially clamped and fixed. When the lifting plate 112 drives the first fixed support 201 and the fixed rotating rod 207 to move downward, the liner body 137 can be squeezed to make the liner body 137 continue to move downward, and drive the compression rotating rod While 212 rotates relative to each other, the supporting spring 210 is stretched, so that the clamping rotating rod 212 drives the first rotating support 218 and the clamping rotating rod 219 to move horizontally. Under the limiting action of the first clamping arm 217, the second rotating support 220 drives the second clamping arm 221 to slide inside the first clamping arm 217, and the bottom of the liner body 137 is clamped for the second time by the first clamping arm 217 and the second clamping arm 221, so as to improve the clamping stability of the liner body 137 and facilitate the bending of the liner body 137.

[0044] Secondly, the adjusting knob 203 is used to drive the adjusting bidirectional threaded rod 204 to rotate, so that the adjusting threaded sleeve 205 can make the adjusting bidirectional threaded rod 204 rotate relatively while the top rotating support 206 drives the fixed rotating rod 207 to rotate around the adjusting rotating shaft 208, which can change the rotation angle and height of the fixed rotating rod 207, so that the liner body 137 of different diameters can be initially fixed, and the lifting motor 107 is used to drive the first sprocket transmission assembly 108 and the lifting bidirectional threaded rod 109 to rotate, so that the lifting threaded sleeve 110 can move relatively on the lifting bidirectional threaded rod 109 while driving the lifting rotating rod 111 to rotate, thereby realizing the lifting and lowering of the lifting plate 112, and moving the top bending roller 131 to the top of the liner body 137. The bending roller 131 has a built-in heating wire, which can realize the heating function of the bending roller 131.

[0045] Finally, the first translation motor 113 drives the first translation rotation rod 114 to rotate, so that the first translation threaded sleeve 115 drives the top bending base 121 and the bending roller 131 to move horizontally, and the top bending roller 131 is moved to the top bending area of ​​the liner body 137 and the liner body 137 is heated, and the second translation motor 116 is started to drive the second sprocket transmission assembly 117 and the second translation threaded rod 118 to rotate, so that the second translation threaded sleeve 119 drives the translation bracket 120 and the bottom bending base 121 to move horizontally, and the bottom bending roller 131 is moved to the area of ​​the bottom of the liner body 137 that needs to be bent to support and heat it at the same time, so as to facilitate the bending of the liner body 137. When the liner body 137 reaches the bending condition, the bending motor 124 can be used to drive the bending threaded rod 125 to rotate to make the liner body 137 be bent. The bent thread bracket 126 drives the bending sliding rod 127 and the bending roller 131 to move up and down, thereby realizing the bending of the liner body 137. After the bending is completed, the cooling water inside the refrigeration box 128 is pumped into the first spiral tube 134 and the second spiral tube 135 through the water inlet pipe 133 by the water pump 132, so as to quickly cool down the bending roller 131, so that the bent liner body 137 can be quickly cooled. At the same time, the first spiral tube 134 and the second spiral tube 135 can heat the water inside and keep the hot water warm through the insulation box 129. When the subsequent liner body 137 needs to be bent, the hot water stored in the insulation box 129 can be pumped into the first spiral tube 134 and the second spiral tube 135, so as to quickly preheat the bending roller 131, thereby achieving the effect of saving energy.
