Description

Technical Field

[0001] This invention relates to the field of corrugated pipe processing and manufacturing, and in particular to a corrugated pipe processing equipment. Background Technology

[0002] Existing metal corrugated pipe processing typically uses water expansion forming. The water expansion process uses pressure to pressurize liquid in a limited space, and the water pressure deforms the material to fit the mold shape. It has the advantages of low processing cost and high production efficiency.

[0003] However, during the processing of corrugated metal pipes, due to the corrugated folds on the pipe wall and the inherent resilience of the metal material, the newly extruded corrugated metal pipe still retains a certain degree of elasticity. When the corrugated metal pipe and the mold are removed from the forming machine, the release of this elasticity causes the corrugated metal pipe to stretch rapidly, which can easily damage the mold and the product. At the same time, in order to have better ductility and flexibility, corrugated metal pipes are usually designed with more corrugated folds and are formed by extrusion. This causes the corrugated folds to clamp the mold's closing position when the mold is opened, making the mold and the product even more susceptible to damage.

[0004] Furthermore, during the forming of the metal corrugated pipe, the pressure is applied to both ends of the pipe. Under the extrusion of the forming machine, the ends of the metal corrugated pipe are easily squeezed by the sealing plugs at both ends, resulting in the defect of deformation at the pipe ends, or even directly causing the metal corrugated pipe to break and be scrapped.

[0017] The beneficial effects of this invention are as follows: In the prior art, when processing metal tubes, the mold is usually removed from the forming machine first, and then the mold is opened. This causes the metal corrugated tube to stretch rapidly when the formed metal tube and the mold are removed from the forming machine due to the release of the rebound force, which can easily damage the mold and the product. This invention, through the second limiting plate and the first limiting plate, allows the first plastic block and the second plastic block to leave the corrugated folds of the corrugated tube in sequence, avoiding the folds from clamping the device and causing damage to the mold and the product. It realizes the material feeding method of removing the mold first and then releasing the formed metal tube, thus avoiding damage to the mold and the product.

[0018] The present invention uses a second spring and a second airbag to absorb the rebound force generated when the molded metal tube is unfolded, further preventing damage to the mold and the product;

[0019] During the processing of this invention, the cross-sections at both ends of the metal tube are not subjected to compressive force, thus avoiding the situation where the metal tube is squeezed and deformed by the sealing plugs at both ends, or even cracked and scrapped.

[0020] This invention uses a water tank in conjunction with two first baffles to collect and settle heavier impurities in the coolant. At the same time, the second baffles block impurities with a density lower than that of the coolant and a large number of air bubbles generated by the flow of the coolant, preventing them from moving to the inlet of the circulation pump. This avoids air bubbles or impurities being pumped into the metal pipe along with the coolant by the circulation pump, which would affect the processing effect. Attached Figure Description

Detailed Implementation

[0034] The following description is only a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.

The circulation pump 2 is installed at the bottom of the support 1. The molding system is connected to the top of the support 1. The sealing system is also connected to the top of the support 1. The molding system is connected to the sealing system. The sealing system seals both ends of the metal tube 100 and adds lubricant to the metal tube 100, filling it with lubricant. When the molding system compresses the metal tube 100 into a corrugated tube, the internal space of the metal tube 100 decreases, increasing the pressure of the lubricant inside. The lubricant expands outwards, making the tube wall of the metal tube 100 fit the mold more closely. When the molding system is opened, the remaining elasticity inside the metal tube 100 is released first, preventing damage to the device from the metal corrugated tube. The circulation system is connected to the bottom of the sealing system and is connected to the support 1 and the circulation pump 2. When the metal tube 100 is removed from the sealing system, the lubricant is recycled and filtered through the circulation system for reuse.

[0040] The compression assembly includes a first push rod 121, a second push rod 122, a mounting bracket 123, and a second limiting plate 124. The tops of the two first limiting plates 115 are each bolted with two first push rods 121. The second push rod 122 is provided in the rear part of the bracket 1. The mounting bracket 123 is fixedly connected to the telescopic part of the second push rod 122. The telescopic parts of the two first push rods 121 on the same side are connected to a second limiting plate 124. Each first limiting plate 115 and the second limiting plate 124 have two transverse grooves and one longitudinal groove. The two transverse grooves are used to guide the first shaping block 131 to move laterally, and the longitudinal groove is used to guide the second shaping block 133 to move longitudinally.

[0042] Each first shaping block 131 has two protrusions at its bottom and two grooves at its top. The protrusions at the bottom of each first shaping block 131 can slide vertically within the grooves at the top of another first shaping block 131 connected to it below. Each second shaping block 133 has one protrusion at its bottom and one groove at its top. The protrusion at the bottom of each second shaping block 133 can slide vertically within the grooves at the top of another second shaping block 133 connected to it below. In each shaping assembly, the topmost first shaping block 131 is slidably connected to a second limiting plate 124, and the two protrusions at the bottom of the bottommost first shaping block 131 pass through the first limiting plate 115 and are fixedly connected to the connecting block 114. The topmost second shaping block 133 is slidably connected to a second limiting plate 124, and the protrusion at the bottom of the bottommost second shaping block 133 is slidably connected to the first limiting plate 115.

[0043] The sealing system includes a bottom sealing assembly and a top sealing assembly; the bottom sealing assembly is connected to the middle of the bracket 1; and the top sealing assembly is connected to the mounting bracket 123.

[0044] The bottom sealing assembly includes a collection pipe 211, a connecting plate 212, a first air inlet pipe 213, a guide block 214, a support frame 216, an inlet pipe 217, a one-way valve 218, and a second spring 219; the collection pipe 211 is vertically inserted through the middle of the support frame 1; two connecting plates 212 are fixedly connected inside the collection pipe 211; the two connecting plates 212 are jointly fixedly connected to the first air inlet pipe 213; three guide blocks 214 are equidistantly arranged around the first air inlet pipe 213; the upper part of the first air inlet pipe 213 is connected to the first air... The first airbag 215 is fixed by embedding its two ends into the wall of the first air inlet pipe 213; a support frame 216 is slidably connected inside the collection pipe 211, and the support frame 216 is slidably connected to the guide block 214, and the support frame 216 is slidably connected to the first airbag 215; the first air inlet pipe 213 is connected to a liquid inlet pipe 217, and the liquid inlet pipe 217 passes through the collection pipe 211; a one-way valve 218 is installed on the liquid inlet pipe 217; three second springs 219 are provided between the support frame 216 and the guide block 214.

[0045] The top sealing assembly includes a connecting pipe 221 and a second air inlet pipe 223; the mounting bracket 123 is connected to the connecting pipe 221; the upper part of the connecting pipe 221 is connected to the second air inlet pipe 223; the lower part of the connecting pipe 221 is connected to the second airbag 222; the outer surfaces of the first airbag 215 and the second airbag 222 are provided with a number of annular protrusions to increase the friction with the metal pipe 100 and achieve a better sealing effect.

[0046] The circulation system includes a water tank 311, a cover plate 312, a waste liquid pipe 313, a first baffle 314, a second baffle 315, and an infusion pipe 316. The water tank 311 is installed at the bottom of the bracket 1, and the right side of the water tank 311 is connected to the circulation pump 2. The top of the water tank 311 is detachably connected to the cover plate 312. The waste liquid pipe 313 passes through the upper front part of the cover plate 312 and is connected to the collection pipe 211. Two first baffles 314 are fixedly connected to the bottom of the water tank 311. The second baffle 315 is fixedly connected to the lower part of the cover plate 312 and is located between the two first baffles 314, so that an S-shaped channel is formed inside the water tank 311. The infusion pipe 316 is connected to the outlet of the circulation pump 2.

[0047] Before the specific operation of this invention:

[0048] First, open the cover plate 312 and add lubricant to the water tank 311. Connect the first air inlet pipe 213 and the second air inlet pipe 223 to the external air pumps respectively. Start the circulation pump 2 to pump the lubricant in the water tank 311 into the delivery pipe 316. The lubricant enters the inlet pipe 217 through the one-way valve 218 to purge the air in the delivery pipe 316 and the inlet pipe 217. This prevents excessive air from entering the metal pipe 100 with the lubricant during the device processing, which would affect the device forming effect. During the air removal process, excess lubricant flows out from the top of the inlet pipe 217, flows down along the outer surface of the first air inlet pipe 213 and the first air bag 215, flows into the collection pipe 211 through the gap of the support frame 216, and then returns to the water tank 311 through the waste liquid pipe 313. After removing the air, turn off the circulation pump 2. This completes the preparation of the device.

[0049] In the specific operation of this invention:

[0050] The metal tube 100, cut to the correct length, is placed vertically on the support frame 216. Then, the four guide rails 112 are controlled to drive the two connecting blocks 114 through the four moving blocks 113. Each of the two connecting blocks 114 drives several first shaping blocks 131 above it to move toward the first airbag 215.

[0051] It should be noted that the initial state of the device is as follows: Figure 7 As shown, the four first springs 117 are in a compressed state, providing a force to the two first limiting plates 115 to move laterally toward the first airbag 215. However, the two first limiting plates 115 are blocked by a connecting block 114 and a first shaping block 131 fixed thereto, respectively, and cannot move toward the first airbag 215. At this time, the positions of the first limiting plates 115 and the set of shaping components above them are relatively fixed.

[0052] When the two connecting blocks 114 move toward the first airbag 215, the two first limiting plates 115 also move toward the first airbag 215 under the action of the four first springs 117. The two first limiting plates 115, through several second shaping blocks 133 above them and the protrusions on their surfaces, drive a second limiting plate 124 to move laterally toward the first airbag 215. When the two first limiting plates 115 contact the metal tube 100, the two first limiting plates 115 restrict the bottom of the metal tube 100, and the two second limiting plates 124 also contact the top of the metal tube 100, restricting the top of the metal tube 100 and preventing the metal tube 100 from tilting. It should be noted that at this time, the clamping force of the two second limiting plates 124 and the two first limiting plates 115 on the metal tube 100 is provided by the four first springs 117. At this time, the clamping force on the metal tube 100 is small, which can only prevent the metal tube 100 from tilting.

[0053] The air pump is controlled to inflate the first air inlet pipe 213. The gas in the first air inlet pipe 213 enters the first air bladder 215, causing the first air bladder 215 to inflate and block the bottom opening of the metal tube 100. Together with the two first limiting plates 115, the first air bladder 215, which was previously uninflated, inflates, pressing the support frame 216 downwards and causing it to move away from the bottom opening of the metal tube 100. At this point, the device is in the following state: Figure 5 As shown on the right, this is to prevent the support frame 216 and the metal tube 100 from squeezing each other during subsequent processing, which could cause deformation at the opening of the metal tube 100.

[0054] Meanwhile, the two connecting blocks 114 continue to drive several first plastic blocks 131 above them to move towards the center of the first airbag 215. The first plastic blocks 131 drive the connecting rods 132 connected to them to move laterally towards the first airbag 215. At this time, the second plastic blocks 133 are restricted by the first limiting plate 115 and cannot move laterally. The first plastic blocks 131 slide in the two transverse grooves opened in the first limiting plate 115, and the connecting rods 132 slide in the arc grooves of the second plastic blocks 133. Under the combined action of the connecting rods 132 and the arc grooves of the second plastic blocks 133, the second plastic blocks 133 move longitudinally towards the first airbag 215 through the longitudinal grooves opened in the first limiting plate 115, so that several second plastic blocks 133 come into contact with the metal pipe 100. At the same time, the circulation pump 2 is started. The circulation pump 2 pumps the coolant in the water tank 311 into the inlet pipe 217. After that, the coolant flows out from the pipe opening of the inlet pipe 217 and enters the metal pipe 100.

[0055] Then, the two connecting blocks 114 continue to drive the several first shaping blocks 131 above them to move towards the center of the first airbag 215, so that the two first limiting plates 115 and the two connecting blocks 114 together clamp the bottom of the metal tube 100. It should be noted that at this time, the connecting rod 132 slides in the straight groove of the second shaping block 133 and will not drive the second shaping block 133 to move; the several first shaping blocks 131 and the several second shaping blocks 133 together wrap the metal tube 100, and the device is in the following state: Figure 8 As shown, at the same time, the second push rod 122 retracts, causing the mounting bracket 123 to drive the second airbag 222 into the top of the metal tube 100 through the connecting pipe 221. When the metal tube 100 is filled with coolant, the circulation pump 2 is turned off, and the air pump is controlled to inflate the second air inlet pipe 223. The gas in the second air inlet pipe 223 enters the second airbag 222 through the connecting pipe 221, causing the second airbag 222 to expand, thereby blocking the top opening of the metal tube 100. It should be noted that at this time, the clamping force of the two second limiting plates 124 and the two first limiting plates 115 on the metal tube 100 is provided by the four first springs 117 and the four guide rails 112. At this time, the clamping force on the metal tube 100 is relatively large, which can keep the metal tube 100 fixed in position even when it is deformed by subsequent extrusion.

[0056] The two second limiting plates 124 and the inflated second airbag 222 together fix the top of the metal tube 100, and the two first limiting plates 115, the inflated first airbag 215 and the two connecting blocks 114 together fix the bottom of the metal tube 100. The metal tube 100 is filled with coolant. At this time, the device is in the following state: Figure 10 As shown on the left;

[0057] The four first push rods 121 and one second push rod 122 are controlled to retract synchronously, causing the two second limiting plates 124 and the inflated second airbag 222 to move downwards, compressing the metal tube 100 downwards. This increases the pressure of the coolant inside the metal tube 100, deforming the tube wall through water pressure and forcing it to conform to the internal shape of the first molding block 131 and the second molding block 133, thus completing the forming process of the metal tube 100. It should be noted that at this time, the ends of the metal tube 100 are not subjected to compressive force. The upper part of the metal tube 100 is driven by the friction between the two second limiting plates 124 and the inflated second airbag 222, while the bottom of the metal tube 100 is fixed by the clamping force between the two first limiting plates 115, the inflated first airbag 215, and the two connecting blocks 114. The device is in the following state at this time: Figure 10 As shown on the right.

[0058] Then, the air pump is controlled to expel the gas from the first airbag 215, reducing its volume and causing it to lose contact with the bottom of the metal tube 100. The coolant inside the metal tube 100 flows out from the bottom of the metal tube 100, flows through the gap in the support frame 216 into the collection pipe 211, and then returns to the water tank 311 through the waste liquid pipe 313. At the same time, the support frame 216 moves upward under the elastic force of the three second springs 219, contacting the bottom of the processed metal tube 100. It should be noted that the coolant first falls into the space between the water tank 311 and the front first baffle 314. Inside, heavier impurities in the coolant settle here. The coolant flows from above the first baffle 314 in front into the space between the two first baffles 314. The remaining impurities in the coolant settle in the space between the two first baffles 314. Impurities with a density less than that of the coolant are blocked by the second baffle 315. At the same time, a large number of air bubbles generated by the flow of coolant are also blocked by the second baffle 315 because they float on the surface of the coolant and cannot move to the back of the water tank 311. This prevents air bubbles or impurities from being pumped into the metal pipe 100 by the circulation pump 2 along with the coolant, which would affect the processing effect.

[0059] Then, the control guide rail 112 drives the connecting blocks 114 to move to the left and right sides of the device, so that the two connecting blocks 114 move away from the metal tube 100. The two connecting blocks 114 drive several first shaping blocks 131 above them to move to the left and right sides of the device, so that all the first shaping blocks 131 leave the outer surface of the metal tube 100. At this time, the two first limiting plates 115 still restrict the bottom of the metal tube 100, and the two second limiting plates 124 and the inflated second airbag 222 together fix the top of the metal tube 100. It should be noted that at this time, the first shaping blocks 131 drive the connecting blocks 114 to move to the left and right sides of the device, so that all the first shaping blocks 131 move away from the outer surface of the metal tube 100. The connecting rod 132 slides within the straight groove of the second molding block 133 without causing the second molding block 133 to move. The first molding block 131 continues to move to the left and right sides of the device, causing the connecting rod 132 to slide within the arc-shaped groove of the second molding block 133, thus moving the second molding block 133 to the front and rear sides of the device. This allows the second molding block 133 to leave the outer surface of the metal tube 100, preventing the corrugated folds processed on the metal tube 100 from trapping the second molding block 133 and the first molding block 131, which could cause the metal tube 100 to get stuck during subsequent demolding, resulting in damage to the metal and the device.

[0060] When the first shaping block 131 on the left bottom and its connected connecting block 114 contact the leftmost end of the transverse groove of the first limiting plate 115, the connecting block 114 on the left drives the first limiting plate 115 on the left to move to the left. The first limiting plate 115 on the left, through several second shaping blocks 133, drives the second limiting plate 124 on the left to move to the left. Similarly, the first limiting plate 115 and the second limiting plate 124 on the right also move to the right, causing the bottom of the metal tube 100 to lose its fixation. The metal tube 100, which has just been extruded, releases its elastic force. Since the top of the metal tube 100 is supported by the expanded second airbag 222, the elastic force causes the metal tube 100 to unfold downwards, causing the bottom of the metal tube 100 to drive the support frame 216 to move downwards. The support frame 216 causes the three The second spring 219 is compressed, thereby absorbing the energy released by the rebound of the metal tube 100. At this time, the bottom of the metal tube 100 is connected to the second airbag 222, and the second airbag 222 can also undergo a certain deformation to absorb energy. Then, the air pump is controlled to discharge the gas in the second airbag 222. Under the elastic force of the three second springs 219, the metal tube 100 is supported by the support frame 216 and moves upward back to its original position. At the same time, the second push rod 122 is controlled to extend, driving the second airbag 222 to rise and return to the initial height. Then, the processed corrugated tube is manually removed from the support frame 216, thus completing one processing of the metal tube 100. The four first push rods 121 are controlled to extend synchronously, so that the device returns to the initial state, which is convenient for the next processing.
