Description

Technical Field

[0001] The present invention belongs to the technical field of electric power pipe forming equipment, and in particular to an MPP electric power pipe forming device and a forming method. Background Art

[0002] With the acceleration of urbanization and the continuous improvement of power facilities, the market demand for power pipes continues to grow. Traditional power pipe materials such as cement pipes and fiberglass pipes have many shortcomings, such as difficult construction and poor environmental protection. MPP power pipes have gradually become the mainstream choice of the market due to their excellent performance and environmental protection. Especially in the construction projects such as laying pipelines and cables in special areas such as roads, railways, buildings, and riverbeds, MPP power pipes have shown their unique advantages.

[0003] The formation of these water stains is mainly due to the fact that the cooling water fails to completely evaporate or drain during the spraying process. When the cooling water is sprayed on the pipe surface, although it can quickly take away the heat and cool the pipe, due to the influence of various factors such as the spraying volume, spraying time, pipe material and shape, some water may be retained on the pipe surface, especially when there are tiny grooves or unevenness on the pipe surface, water is more likely to accumulate.

[0004] Residual water stains will not only affect the appearance quality of the power pipe, but may also have an adverse effect on its performance. For example, water stains may cause rust and corrosion on the surface of the pipe, thereby reducing its service life. In addition, in the subsequent cutting and winding process, water stains may also affect the flatness of the cutting surface and the winding effect, and even cause the pipe to be deformed or damaged during transportation and installation. Therefore, it needs to be improved and optimized. Summary of the invention

[0016] A forming method of an MPP power pipe forming device, the specific steps of the method include:

[0017] S1. Raw material heating and extrusion: The MPP raw material is added to the extruder, heated and melted, and then extruded through a die to form a continuous tubular billet;

[0018] S2. Cooling and shaping: The extruded tubular billet immediately enters the cooling system, and the billet is quickly cooled and shaped by the cooling water;

[0019] S3. Traction and straightening: After cooling and shaping, the power pipe is pulled by the traction device and straightened by the straightening device;

[0020] S4. Cutting and reeling: The power tube is cut by the cutting device according to the set length; the cut power tube is reeled by the reeling device.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] The present invention solves the problem of water stains on the surface of the pipe by arranging a linkage mechanism between the sponge ring and the half gear. When the pipe is sprayed and cooled, a large amount of moisture often remains on its surface. If the moisture is not removed in time, the subsequent processing quality may be affected. The motor drives the rotating rod 1 and the rotating rod 2 to rotate in opposite directions, and the half gear rotates accordingly and meshes with the tooth block, driving the tooth block to reciprocate in the horizontal direction. The sponge ring is periodically squeezed by the extrusion ring to squeeze out the saturated water in the sponge ring, thereby ensuring the continuous water absorption capacity of the sponge ring, so that when the pipe passes through the other side of the partition, the water stains on its surface can be effectively adsorbed, thereby ensuring the dryness of the pipe and providing a strong guarantee for subsequent processing.

[0023] The present invention allows the operator to adjust the height of the box by pulling out the sliding rod and rotating the eccentric wrench. The lifting movement of the box is realized by the threaded connection between the screw rod and the base, which ensures the stability and accuracy of the lifting process. When the box is aligned with the outlet of the heating extruder on the assembly line, the pipe can smoothly enter the box for spraying and cooling treatment, which not only improves the production efficiency but also reduces the difficulty of operation, making the switching of equipment between different production lines more convenient.

[0024] After the water pump is started, the cooling water is pumped to the nozzle through the water pipe to spray and cool the pipe. At the same time, the refrigerator cools the water at the bottom through the refrigeration pipe to prevent the water temperature from being too high and affecting the cooling effect. The sprayed water is adsorbed and squeezed by the sponge ring, and then enters the other side of the partition through the inclined plate and the filter hole to continue to participate in the circulation spraying operation. This not only improves the utilization efficiency of the cooling water, but also ensures the uniformity and stability of the pipe during the cooling process. The circulation spray cooling mechanism enables the pipe to always maintain a suitable temperature state during the processing, providing strong support for the production of high-quality products.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] like Figures 1 to 10 As shown, the present invention provides an MPP power pipe forming device, comprising a box body 1, a partition 101 is fixedly installed inside the box body 1, sponge rings 2 are fixedly installed on the partition 101 and the corresponding inner wall of the box body 1, and extrusion rings 201 are fixedly installed on the sides of the two sponge rings 2 close to each other, and two groups of extrusion mechanisms are arranged on the outer wall of the partition 101;

[0038] The extrusion mechanism includes a mounting plate 1011 fixedly mounted on the outer wall of the partition 101, on the outer wall of the mounting plate 1011, a rotating rod 1 5 and a rotating rod 2 7 are rotatably mounted, and a gear 8 and a half gear 801 are fixedly sleeved on the outer walls of the rotating rod 1 5 and the rotating rod 2 7, respectively. Two convex slide rails 3 are fixedly mounted on the side where the box body 1 and the partition 101 are close to each other, and a gear block 4 is slidably mounted on the side where the two convex slide rails 3 are close to each other, and the gear block 4 is fixedly connected to the two extrusion rings 201.

[0039] Through the design of the extrusion mechanism, that is, the coordinated action of the rotating rod 1 5, the rotating rod 2 7, the gear 8, the half gear 801 and the tooth block 4, the periodic extrusion of the sponge ring 2 is realized. This design can efficiently squeeze out the saturated water in the sponge ring 2, thereby ensuring the continuous water absorption capacity of the sponge ring 2. When the pipe passes through the sponge ring 2, the water stains on its surface can be quickly absorbed, ensuring the dryness of the pipe, providing a strong guarantee for subsequent processing.

[0040] like Figures 8 to 9 As shown, a fixed block 2 18 is fixedly installed on the bottom of the box body 1, a rotating rod 4 19 is rotatably installed inside the fixed block 2 18, a bevel gear 3 1902 is fixedly installed on one end of the rotating rod 4 19, two T-shaped blocks 1901 are fixedly installed on the outer walls of both sides of the rotating rod 4 19, a sliding sleeve 20 is slidably installed on the outer wall of the rotating rod 4 19, and sliding grooves 2001 are respectively provided on both sides of the sliding sleeve 20, and the two sliding grooves 2001 are respectively slidably connected with the corresponding T-shaped blocks 1901, an eccentric wrench 2002 is rotatably installed on the front of the sliding sleeve 20, a sliding rod 21 is slidably installed inside the sliding sleeve 20, two fixed blocks 13 are fixedly installed on the bottom of the box body 1, and rotating rods 3 14 are rotatably installed inside the two fixed blocks 13, and three bevel gears 1401 are fixedly sleeved on the outer wall of the rotating rod 3 14, and the bevel gear 1 1401 located in the middle is meshed with the bevel gear 3 1902.

[0041] By means of the sliding connection between the rotating rod 4 19 and the T-shaped block 1901 thereon and the slide groove 2001 in the slide sleeve 20, the stable sliding and positioning of the slide sleeve 20 on the rotating rod 4 19 is achieved. This design allows the operator to adjust the position of the slide sleeve 20 by rotating the eccentric wrench 2002, and then achieve precise adjustment of the box body 1 relative to other parts of the production line through the connection between the slide rod 21 and the bottom of the box body 1. Once adjusted to the desired position, the eccentric wrench 2002 can lock the slide sleeve 20 to prevent it from moving during operation.

[0042] like Figures 4 to 5 As shown, a motor 6 is fixedly installed on the top of the box body 1, and the output shaft of the motor 6 is fixedly connected to the corresponding rotating rod 5, and pulleys 501 are fixedly sleeved on the outer walls of the two rotating rods 5, and the two pulleys 501 are connected through a belt 502. An inclined plate 9 is arranged under the two sponge rings 2, and the inclined plate 9 passes through the partition 101 and is fixedly connected to the partition 101. A plurality of filter holes 10 are opened on the top of the inclined plate 9, and the plurality of filter holes 10 are designed to be equidistantly distributed.

[0043] Inclined plates 9 are arranged under the sponge rings 2 in the device. These inclined plates 9 penetrate the partition 101 and are fixedly connected to the partition 101. The design of the inclined plates 9 allows the squeezed water to flow smoothly to the filter holes 10 on the top thereof. The filter holes 10 are designed to be distributed at equal distances, which not only ensures the uniform discharge of water, but also can effectively filter out impurities and particles in the water to prevent them from clogging the drainage system.

[0044] like Figures 2 to 3As shown, a water pump 12 is fixedly installed on the front of the box 1, a water pipe 1201 is fixedly installed on the bottom of the water pump 12, the other end of the water pipe 1201 extends into the box 1, a water pipe 2 1202 is fixedly installed on the top of the water pump 12, the other end of the water pipe 2 1202 extends into the box 1 and is fixedly connected to the inner wall of the box 1, a plurality of nozzles 12021 are fixedly installed on the bottom of the water pipe 2 1202, a refrigerator 11 is fixedly installed on the back of the box 1, a refrigeration pipe 1101 is fixedly installed on the bottom of the box 1, and the back of the refrigeration pipe 1101 extends out of the box 1 and is fixedly connected to the refrigerator 11.

[0045] Through the integrated design of the refrigerator 11 and the refrigeration pipe 1101 in the device, a stable, low-temperature cooling water source is provided for the circulating cooling system. The refrigerator 11 circulates the cooling water to the box body 1 through the refrigeration pipe 1101 to ensure that the cooling water is always kept in a suitable low temperature range. By combining accessories such as the water pump 12, water pipe 1 1201, water pipe 2 1202, nozzle 12021, refrigerator 11 and refrigeration pipe 1101, the dual effects of spray cooling and refrigeration cooling are achieved, which not only improves the cooling speed of the pipe, but also ensures the dimensional stability and quality consistency of the pipe during the molding process. At the same time, the efficient combination of spraying and cooling also shortens the production cycle and improves the overall production efficiency.

[0046] like Figures 8 to 10 As shown, two screw rods 15 are rotatably installed at the bottom of the box body 1, and bevel gears 1501 are fixedly sleeved on the outer walls of the two screw rods 15, and the two bevel gears 1501 are respectively meshed with the corresponding bevel gears 1401. Bases 16 are threadedly sleeved on the outer walls of the two screw rods 15, and two rectangular grooves 1601 are respectively provided on the tops of the two bases 16. Limiting links 17 are respectively hingedly installed inside the four rectangular grooves 1601. The tops of the four limiting links 17 are hinged to the bottom of the box body 1, and the four limiting links 17 are respectively composed of two short links hinged to each other.

[0047] The screw rod 15 is driven to rotate by installing two screw rods 15 at the bottom of the box body 1, and the bevel gear 2 1501 on the outer wall of the screw rod 15 is meshed with the bevel gear 1 1401 on the rotating rod 3 14. When the rotating rod 3 14 is driven to rotate by the bevel gear 3 1902, the screw rod 15 will also rotate accordingly through the meshing transmission of the bevel gears. Since the screw rod 15 and the base 16 are connected by a threaded sleeve, the rotation of the screw rod 15 will drive the base 16 to move up and down, thereby adjusting the height of the box body 1.

[0048] A forming method of an MPP power pipe forming device, the specific steps of the method include:

[0049] S1. Raw material heating and extrusion: The MPP raw material is added to the extruder, heated and melted, and then extruded through a die to form a continuous tubular billet;

[0050] S2. Cooling and shaping: The extruded tubular billet immediately enters the cooling system, and the billet is quickly cooled and shaped by the cooling water;

[0051] S3. Traction and straightening: After cooling and shaping, the power pipe is pulled by the traction device and straightened by the straightening device;

[0052] S4. Cutting and reeling: The power tube is cut by the cutting device according to the set length; the cut power tube is reeled by the reeling device.

[0053] The working principle and use process of the present invention:

[0054] First, the slide bar 21 is pulled outward, and then the eccentric wrench 2002 is rotated so that the eccentric wrench 2002 no longer contacts the outer wall of the slide bar 21. Then the slide bar 21 is pulled out horizontally, and then the eccentric wrench 2002 is rotated to fix the slide bar 21. The operator holds the slide bar 21 and rotates it, and the slide bar 21 drives the rotating rod 4 19 to rotate, and the rotating rod 4 19 drives the bevel gear 3 1902 to rotate, and the bevel gear 3 1902 is meshed with the middle bevel gear 1 1401, thereby driving the rotating rod 3 14 to rotate, and the rotating rod 3 14 is rotated. The three 14 drives the bevel gears 1401 on both sides to rotate, and the bevel gears 1401 on both sides mesh with the bevel gears 1501 on both sides, so that the bevel gears 1501 drive the screw rod 15 to rotate, and the screw rod 15 base 16 is connected to the bottom of the box body 1 through the threaded connection, so that the screw rod 15 is connected to the base 16 through the threaded connection to perform up and down lifting movement, so that the box body 1 can be aligned with the outlet of the heating extruder in the previous step on the assembly line, so that the pipe can smoothly enter the box body 1;

[0055] When the extruded tubular blank enters the box body 1, the water pump 12 is started to pump the cooling water at the bottom of the box body 1 to the nozzle 12021 of the water pipe 1202 through the water pipe 1201 to spray and cool the extruded tubular blank. At the same time of spraying, the refrigerator 11 is started to cool the water at the bottom through the cooling pipe 1101 to prevent the water temperature from being too high to effectively cool the material;

[0056] After being sprayed and cooled, the pipe continues to move and enters the other side of the partition 101. Through the contact between the pipe and the two sponge rings 2, the water stains on the surface are absorbed. Due to the long-term use of the sponge ring 2, it will be too saturated with water and cannot continue to absorb water. At this time, it is necessary to start the motor 6, and the output shaft of the motor 6 drives the corresponding rotating rod 1 5 to rotate. The two rotating rods 1 5 are driven by the belt 502 to rotate, and the two rotating rods 1 5 drive the two gears 8 on the outer wall of the rotating rod 2 7 to rotate. Through the meshing with the two gears 8 on the outer wall of the rotating rod 2 7, the two rotating rods 1 5 and the rotating rod 2 7 rotate in opposite directions, thereby driving The half gears 801 on the outer walls of the movable rotating rod 1 5 and the rotating rod 2 7 rotate. When the two half gears 801 rotate, one of them will mesh with the adjacent tooth block 4, while the other will not contact the tooth block 4, so that the tooth block 4 reciprocates in the horizontal direction under the opposite rotation of the two half gears 801, thereby squeezing the corresponding sponge rings 2 through the two squeezing rings 201, so that the moisture in the two sponge rings 2 is squeezed out, which can continue to absorb water stains on the pipe, and the squeezed water enters the other side of the partition 101 through the inclined plate 9 and the filter hole 10 on the top of the inclined plate 9, and continues the residual circulation spraying operation.
