Description

Technical Field

[0001] This utility model belongs to the field of HDPE corrugated pipe technology, and in particular relates to a cutting structure for HDPE corrugated pipe. Background Technology

[0002] Corrugated pipe refers to a tubular elastic sensitive element made of foldable corrugated sheets connected along the folding and expansion direction. HDPE corrugated pipe is a new type of lightweight pipe material made of high-density polyethylene. It has the characteristics of light weight, low price, high pressure resistance, good toughness, fast construction, and long service life. Due to its convenient and reliable connection, it is widely used in petrochemical, instrumentation, aerospace, chemical, power, water conservancy, metallurgy and other industries. However, in the production and processing of HDPE corrugated pipe, it is often necessary to cut the corrugated pipe, which has been processed to a long length at once, into suitable lengths to facilitate the storage, transportation and use of HDPE corrugated pipe in different fields. However, it still has the following drawbacks in actual use:

[0003] 1. Utility model with publication number CN220614218U discloses a corrugated pipe cutting device. By setting a clamping mechanism, the upper and lower cutting sleeves are brought closer and further apart by the first driving component, thereby clamping and positioning the area of ​​the corrugated pipe to be cut, which is used to constrain the displacement of the area of ​​the corrugated pipe to be cut during cutting. After the upper and lower cutting sleeves are brought closer together, a cutting channel is formed. The cutting tool is driven through the cutting channel by the second driving component to complete the cutting of the corrugated pipe. Since HDPE corrugated pipe has a certain elasticity, in order to avoid the vibration of the corrugated pipe causing the cutting position to shift during the cutting process, a relatively precise cutting structure and positioning device are usually required, resulting in high cost and maintenance expenses of the device.

[0004] 2. Because HDPE corrugated pipes have a certain degree of elasticity, they will inevitably deform during the cutting process using a cutting structure, resulting in uneven cuts and requiring a longer time for loading and unloading, thus reducing processing efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a cutting structure for HDPE corrugated pipes. By using a quick-freezing box, a rotating motor, and a positioning cylinder, it solves the problems that when cutting HDPE corrugated pipes, due to their elasticity, the device needs to have high processing precision, resulting in high device cost and maintenance expenses. However, it is still difficult to avoid problems such as deformation and displacement of the corrugated pipe during the cutting process, which leads to low cut flatness and requires a long time for loading and unloading the corrugated pipe.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a cutting structure for HDPE corrugated pipe, including a quick-freezing box, a rotating motor and a positioning cylinder. A heat-insulating water inlet pipe is inserted and snapped through the top of one side of the quick-freezing box. The rotating motor and the positioning cylinder are snapped into the top of the quick-freezing box. A positioning airbag and a sealing airbag are provided at the bottom of the rotating motor. A cutting wheel is provided at the bottom of the positioning cylinder.

[0008] Water is poured into the inside of the corrugated pipe through an insulated water inlet pipe, and then frozen in a quick-freezing chamber. This rapid freezing solidifies the water, shaping the corrugated pipe and ensuring its stability during cutting. The device is simple in structure and easy to operate, significantly reducing processing and maintenance costs. A rotating motor drives the corrugated pipe to rotate, facilitating the cutting wheel's cut. A positioning airbag stretches the corrugated pipe, ensuring its stability during water pouring. A sealing airbag seals the bottom of the corrugated pipe, preventing water leakage. A positioning cylinder moves the cutting wheel up and down, allowing for cutting at appropriate locations on the corrugated pipe surface, thus improving ease of use.

[0009] Furthermore, an insulation cover is rotatably snapped onto one side of the quick-freezing box, a waste bin is snapped onto the bottom side of the quick-freezing box, and shock-absorbing pads are snapped and fixed around the bottom of the quick-freezing box.

[0010] The waste bin catches the falling ice fragments after cutting, and the shock-absorbing pad reduces the impact of ground vibration on the cutting process, ensuring stability. After the corrugated pipe is positioned in the quick-freezing box, water is poured into the corrugated pipe through the insulated water inlet pipe and frozen in the quick-freezing box. The ice inside the corrugated pipe helps to shape the pipe, preventing large vibrations during cutting due to its elastic material, thus ensuring cutting efficiency. The structure is simple, easy to operate, and greatly reduces processing costs and maintenance expenses.

[0011] Furthermore, a heating support rod is snapped onto the bottom of the rotating motor, and a first support frame is welded and fixed to the outer circumference of the heating support rod. The positioning airbag is snapped and fixed to the outer circumference of the first support frame. A first air pump is snapped through one end of the top of the first support frame. The first air pump and the positioning airbag are connected through the first support frame. A material inlet is opened through the top of the first support frame. The heating support rod is inserted through the top of the quick-freezing box. One end of the heat-insulating water inlet pipe hangs over the top of the material inlet.

[0012] When positioning the corrugated pipe, the corrugated pipe is fitted onto the surface of the heating support rod and the upper end of the corrugated pipe is attached to the outside of the first support frame. The positioning airbag is inflated by the first air pump to expand and squeeze and position it on the inner wall of the corrugated pipe, thereby positioning the corrugated pipe and ensuring its stability during the water pouring process.

[0013] Furthermore, an extension tube is slidably snapped onto the bottom of the outer periphery of the heating support rod, a second support frame is welded and fixed to the bottom of the extension tube, a sealing airbag is snapped and fixed to the top of the second support frame, a second air pump is snapped through the bottom of the second support frame, and the second air pump and the sealing airbag are connected through the air.

[0014] During the positioning of the corrugated pipe, the inner bottom of the corrugated pipe is fitted onto the outer circumference of the sealing airbag. The sealing airbag is then inflated by a second air pump, causing it to collide with and press against the inner wall of the corrugated pipe, sealing the bottom of the corrugated pipe and preventing water poured into the corrugated pipe from flowing out. After the corrugated pipe is cut, the ice is heated by the heating support rod, which can quickly melt the ice adhering to the support rod and the surface of the extension pipe, allowing the corrugated pipe to be quickly removed. The loading and unloading operation is simple and convenient, improving processing efficiency.

[0015] Furthermore, a telescopic tube is slidably engaged at the bottom of the positioning cylinder, a drive assembly is engaged at the bottom of the telescopic tube, a sliding groove is provided at the bottom of the drive assembly, and the telescopic tube is inserted through and connected to the top of the quick-freezing box.

[0016] The positioning cylinder can drive the extension and retraction of the telescopic tube, and adjust the height of the cutting wheel. The drive assembly has a cylinder inside, which can adjust the distance between the cutting wheel and the corrugated pipe, making it convenient to cut the corrugated pipe at different positions and to cut corrugated pipes of different sizes, thus improving the ease of use of the cutting structure.

[0017] Furthermore, a cutting motor is rotatably engaged at the top of the cutting wheel, and a slider is fixedly engaged at the top of the cutting motor, with the slider slidably engaged at the bottom of the groove.

[0018] The cutting motor can drive the cutting wheel to move at high speed, quickly cutting the corrugated pipe and improving the automation of the cutting structure.

[0019] This utility model has the following beneficial effects:

[0020] 1. This utility model solves the problem that HDPE corrugated pipes, due to their elasticity, require precise cutting structures and positioning devices during cutting to prevent vibration and displacement, leading to high costs and maintenance expenses. This is achieved by using a quick-freezing chamber and a rotating motor. After the corrugated pipe is positioned and installed, water is poured into it through an insulated water inlet pipe. A sealed airbag prevents water from flowing out from the bottom of the pipe. The quick-freezing chamber then freezes the water inside the pipe. The solidified ice shapes the corrugated pipe, ensuring its stability during cutting. The elastic pipe wall is supported by the ice, preventing vibration and deformation. The device is simple in structure, easy to operate, and significantly reduces processing and maintenance costs.

[0021] 2. This utility model solves the problem that HDPE corrugated pipes, due to their elasticity, inevitably deform during cutting using a cutting structure, resulting in uneven cuts and requiring lengthy loading and unloading processes, thus reducing processing efficiency. By incorporating a quick-freezing box and a rotating motor, the new design addresses this issue. During positioning, the corrugated pipe is fitted onto the outside of the heating support rod and extension tube. The positioning and sealing airbags are inflated, expanding and pressing against the top and bottom inner walls of the corrugated pipe, thus completing its positioning. After cutting, the ice inside the corrugated pipe is heated by the heating support rod, melting the ice and creating a gap between the ice and the heating support rod and extension tube, allowing workers to quickly remove the cut corrugated pipe. The loading and unloading operation is simple and convenient, improving production efficiency. Attached Figure Description

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0030] Please see Figure 1-5As shown, this utility model is a cutting structure for HDPE corrugated pipe, including a quick-freezing box 1, a rotating motor 2 and a positioning cylinder 3. A heat-insulating water inlet pipe 101 is inserted and snapped through the top of one side of the quick-freezing box 1. The rotating motor 2 and the positioning cylinder 3 are snapped and snapped into the top of the quick-freezing box 1. A positioning airbag 204 and a sealing airbag 208 are provided at the bottom of the rotating motor 2. A cutting wheel 301 is provided at the bottom of the positioning cylinder 3.

[0031] Open the insulation cover 102 and attach the HDPE corrugated pipe to the outer circumference of the heating support rod 201 and the extension pipe 202, so that the top of the corrugated pipe is located outside the first support frame 203 and the bottom is located outside the sealing airbag 208. Inflate the positioning airbag 204 and the sealing airbag 208 with the first air pump 205 and the second air pump 209, so that the positioning airbag 204 and the sealing airbag 208 expand and press against the inner wall of the corrugated pipe. Close the insulation cover 102 and pour water into the corrugated pipe through the insulation water inlet pipe 101. Then, refrigerate the water in the corrugated pipe through the quick-freezing box 1. Freezing causes water to solidify rapidly, shaping the corrugated pipe. Positioning cylinder 3 drives telescopic tube 302 to extend and retract, moving cutting wheel 301 to the required cutting height. Sliding block 305 slides along slide groove 304, moving cutting wheel 301 towards the surface of corrugated pipe. Cutting motor 306 is started to drive cutting wheel 301 to rotate at high speed to cut corrugated pipe. After cutting, ice is heated by heating support rod 201, creating a gap between ice, heating support rod 201, and extension tube 202, making it easy for workers to quickly remove the cut corrugated pipe.

[0032] Among them, such as Figure 1-2 As shown, a heat preservation cover 102 is rotatably snapped onto one side of the quick-freezing box 1, a waste bin 103 is snapped onto the bottom side of the quick-freezing box 1, and shock-absorbing pads 104 are snapped and fixed around the bottom of the quick-freezing box 1.

[0033] Before cutting, water is poured into the inside of the corrugated pipe through the insulated water inlet pipe 101, and the water is frozen through the quick-freezing box 1. The ice inside the corrugated pipe shapes the corrugated pipe to prevent large vibrations during the cutting process due to its elastic material. The ice fragments during the cutting process fall into the waste bin 103 for collection.

[0034] Among them, such as Figure 1 , 3As shown, a heating support rod 201 is snapped onto the bottom of the rotating motor 2. A first support frame 203 is welded and fixed to the outer circumference of the heating support rod 201. A positioning airbag 204 is snapped and fixed to the outer circumference of the first support frame 203. A first air pump 205 is snapped through one end of the top of the first support frame 203. The first air pump 205 and the positioning airbag 204 are connected through the inside. A material inlet 206 is opened through the top of the first support frame 203. The heating support rod 201 is inserted through the top of the quick-freezing box 1. One end of the heat preservation water inlet pipe 101 hangs over the top of the material inlet 206. An extension pipe 202 is slidably snapped onto the bottom of the outer circumference of the heating support rod 201. A second support frame 207 is welded and fixed to the bottom of the extension pipe 202. A sealing airbag 208 is snapped and fixed to the top of the second support frame 207. A second air pump 209 is snapped through the bottom of the second support frame 207. The second air pump 209 and the sealing airbag 208 are connected through the inside.

[0035] When positioning the corrugated pipe, the corrugated pipe is fitted onto the outer circumference of the heating support rod 201 and the extension tube 202, with the upper end of the corrugated pipe attached to the outside of the first support frame 203 and the bottom end located outside the second support frame 207. The positioning airbag 204 and the sealing airbag 208 are inflated by the first air pump 205 and the second air pump 209, causing them to expand and press against the inner wall of the corrugated pipe to position the corrugated pipe and prevent water poured into the corrugated pipe from flowing out from the bottom of the corrugated pipe. When cutting, the motor 2 is rotated to drive the heating support rod 201 and the extension tube 202 to rotate, which in turn drives the corrugated pipe to rotate, making it easier to cut the corrugated pipe at various angles. After cutting, the heating support rod 201 is turned on to heat the ice, melting the ice attached to the surface of the heating support rod 201 and the extension tube 202, making it easier for the staff to quickly remove the corrugated pipe.

[0036] Among them, such as Figure 1 , 4 As shown in Figure 5, a telescopic tube 302 is slidably connected to the bottom of the positioning cylinder 3, a drive assembly 303 is connected to the bottom of the telescopic tube 302, a slide groove 304 is opened at the bottom of the drive assembly 303, the telescopic tube 302 is inserted through and inserted into the top of the quick-freezing box 1, a cutting motor 306 is rotatably connected to the top of the cutting wheel 301, a slider 305 is fixedly connected to the top of the cutting motor 306, and the slider 305 is slidably connected to the bottom of the slide groove 304;

[0037] During cutting, the positioning cylinder 3 drives the telescopic tube 302 to extend and retract, adjusting the height of the cutting wheel 301. The drive assembly 303 drives the slider 305 to move along the slide groove 304, bringing the cutting wheel 301 close to the corrugated pipe. The cutting motor 306 drives the cutting wheel 301 to rotate at high speed to cut the corrugated pipe.

[0038] The specific working principle of this utility model is as follows: Open the insulation cover 102, attach the corrugated pipe to the outer circumference of the heating support rod 201 and the extension pipe 202, ensuring the upper end of the corrugated pipe is against the outside of the first support frame 203 and the bottom end is located outside the second support frame 207. Inflate the positioning airbag 204 and the sealing airbag 208 using the first air pump 205 and the second air pump 209, causing them to expand and press against the inner wall of the corrugated pipe, thus positioning the corrugated pipe. Close the insulation cover 102 and freeze the water using the quick-freezing box 1. The ice inside the corrugated pipe shapes it, preventing excessive vibration during cutting due to its elastic material. The positioning cylinder 3 drives the telescopic pipe 302. The height of the cutting wheel 301 is adjusted by the extension and retraction of the cutting wheel 301. The drive assembly 303 drives the slider 305 to move along the slide groove 304, so that the cutting wheel 301 approaches the corrugated pipe. The cutting motor 306 drives the cutting wheel 301 to rotate at high speed to cut the corrugated pipe. During the cutting process, the rotating motor 2 drives the heating support rod 201 and the extension tube 202 to rotate, which further drives the corrugated pipe to rotate, making it easier to cut the corrugated pipe at various angles. The ice fragments during the cutting process fall into the waste bin 103 for collection. After the cutting is completed, the heating support rod 201 is turned on to heat the ice, so that the ice attached to the surface of the heating support rod 201 and the extension tube 202 melts, making it easier for the staff to quickly remove the corrugated pipe.

[0039] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
