Description

Technical Field

[0001] The invention relates to the technical field of pipeline cutting, and in particular to a cutting device for processing polyurethane thermal insulation pipes. Background Art

[0002] Polyurethane insulated pipe, full name: high-density polyethylene plastic outer polyurethane foam prefabricated direct buried insulated pipe, is composed of a working steel pipe for conveying medium, a polyurethane insulation layer, and a polyethylene plastic outer protective pipe, which are combined outward in sequence through equipment. The advantages and characteristics of prefabricated direct buried insulated pipes are: 1. Reduce the cost of the project. According to calculations by relevant departments, double-pipe heating pipes can generally reduce the cost of the project by about 25% (using glass fiber reinforced plastic as a protective layer) and 10% (using high-density polyethylene as a protective layer). 2. Low heat loss and energy saving. Its thermal conductivity is much lower than other commonly used pipe insulation materials in the past, and the insulation effect is improved by 4-9 times. In addition, its water absorption rate is very low, about 0.2kg / m2. The reason for the low water absorption rate is that the closed-cell rate of polyurethane foam is as high as about 92%. The low thermal conductivity and low water absorption, together with the insulation layer and the high-density polyethylene or fiberglass protective shell with good waterproof performance on the outside, have changed the situation of "wearing a wet cotton jacket" in the traditional trench laying of heating pipes, and greatly reduced the overall heat loss of the heating pipes. The heat loss of the heating network is 2%, which is less than the international standard requirement of 10%.

[0003] Polyurethane insulated pipes are widely used, but the polyurethane insulated pipes of the prior art need to be cut to a certain length during the production and delivery stage, but the pipe cutting mechanism of the prior art is not effective. Compared with traditional pipes, due to the particularity of the use scenarios of polyurethane insulated pipes, the diameter of the pipes produced is generally larger. The traditional method uses manual cutting, which is not only time-consuming and labor-intensive, but also has low cutting accuracy. With the continuous improvement of technology, some manufacturers use automated cutting knives for cutting, but the diameter of polyurethane insulated pipes is relatively large. If simple downward pressure cutting is used, the diameter of the cutting knife also needs to be very large, which not only greatly increases the production cost, but also the cutting knife with a larger diameter often gets stuck and heats up abnormally when cutting the polyurethane insulated pipe, which can easily damage the cutting knife and affect the accuracy of the cutting port of the polyurethane insulated pipe. At the same time, when our unit was studying and researching the polyurethane thermal insulation pipe production and processing industry, it was found that the pipe cutting mechanism efficiency of most polyurethane thermal insulation pipe manufacturers was reduced and the cutting accuracy needed to be improved. At the same time, the finished pipes after cutting still needed to be collected manually, which posed a great safety hazard. This seriously affected the efficiency of the efficient production and cutting of polyurethane thermal insulation pipes and restricted the pursuit of production profitability by the working conditions enterprises.

DETAILED DESCRIPTION

[0019] 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.

[0020] It should be noted that, in the specific implementation of the present invention, the possible terms such as "first" and "second" and other relational terms are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.

In the absence of further restrictions, the possible statements "including one" and other defined elements do not exclude the existence of other identical elements in the process, method, article or equipment including the elements.

[0021] In the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "provided with" that may appear should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be internal communication between two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0022] Example 1: Figures 1 to 8 As shown: A cutting device for processing polyurethane insulation pipes, comprising a base 1, a supporting mechanism 2, a cutting mechanism 3 and an adjusting mechanism 4. The invention has a compact structure, a simplified manufacturing process, and an improved dynamic balance of the structure; compared with the same power cutting mechanism cutting pipes, it saves more than 20% of materials, effectively reducing the manufacturing cost; at the same time, it also effectively improves the cutting efficiency and cutting accuracy of the polyurethane insulation pipe. The base 1 is distributed on the left and right. Among them, if Figure 1 As shown: the support mechanism 2 includes a support roller 21, a support frame 22 and a driving member 23. The support frame 22 is concave as a whole, and there are two support frames symmetrically distributed front and back, and the support frame can move forward and backward relative to the base. The support roller 21 can be rotatably adapted to be installed on the support frame 22; specifically, connecting shafts are set at both ends of the support roller, and the connecting shafts are connected to the side walls of the support frame through bearings. The purpose of such a setting is to improve the adaptability of the production and cutting of polyurethane insulation pipes of different specifications and diameters on the basis of ensuring the transportation stability of the polyurethane insulation pipe.

[0023] In this embodiment, Figure 3As shown: the driving member 23 is used to drive the supporting rollers 21 on the front and rear supporting frames 22 to move away from and approach each other, so as to complete the stable support and conveying operation of polyurethane insulation pipes of different diameters and sizes. Specifically, the driving member 23 includes a radial slide rail 231, a radial slider 232, a radial fixing block 233, a radial screw rod 234, an auxiliary plate 235 and a radial motor 236. The radial slide rail 231 is arranged on the base 1 in a front-to-back distribution and is located on the left side of the upper end surface of the base 1; the radial slide rail and the base can be connected and fixed by screws. The radial slider 232 is fixedly installed at the lower end of the supporting frame 22, and the radial slider 232 is kept matched with the radial slide rail 231; the radial fixing block 233 is fixedly installed in the middle of the supporting frame 22. In a preferred technical solution, the radial slider 232 is two symmetrically distributed on the left and right sides, and the radial slider 232, the radial fixing block 233 and the supporting frame 22 can be fixed by welding. The auxiliary plates 235 are arranged on the base 1, and are two distributed front and back, and the two can be fixed by welding, in order to provide support and rotation stability for the radial screw rod. The radial motor 236 is fixedly installed on the base 1 through a bracket, and the radial motor adopts a servo control motor, and the control position movement is more accurate.

[0024] Among them, Figure 3As shown, the radial screw 234 is distributed front and back, and is connected to the two auxiliary plates 235 through bearings, and the radial screw 234 is connected to the radial motor 236; with such a configuration, the radial motor can drive the radial screw to rotate synchronously. The radial screw 234 is divided into a front section and a rear section, and the thread rotation direction of the front section is opposite to that of the rear end. The front section and the rear section of the radial screw 234 are respectively threadedly connected to the radial fixing block 233 on the front side and the radial fixing block 233 on the rear side. With such a configuration, when the radial motor starts to rotate forward, it will drive the radial screw to rotate clockwise, and then, under the cooperation of the radial screw and the radial fixing block, a "screw nut" structure is formed. At this time, the radial slide rail and the radial slider play an auxiliary role in position guidance, so that the radial screw drives the two support frames and the support roller to approach each other as a whole. This state can be applied to the support, transportation and cutting operations of polyurethane insulation pipes with smaller diameters. When the radial motor starts to reverse, it will drive the radial screw to rotate counterclockwise, and then the radial screw drives the two support frames and the support rollers to move away from each other as a whole. This state can be applied to the support, transportation and cutting operations of polyurethane insulation pipes with larger diameters. In this way, the present invention further adopts the settings of radial slide rails, radial sliders, radial fixing blocks, radial screws, auxiliary plates and radial motors to drive the support rollers on the front and rear support frames to move away from or close to each other, so as to complete the stable support and transportation operations of polyurethane insulation pipes of different diameters and sizes. The optimized structural design improves the stability of pipeline support and transportation, and has stronger adaptability, avoiding the problem that the existing technology still needs to replace the support platform when facing the cutting and transportation operations of polyurethane insulation pipes of different specifications and models.

[0025] like Figure 1 and Figure 4As shown: In this embodiment, the cutting mechanism 3 includes a fixed plate 31, a crossbeam 32, a first cylinder 33, a mounting seat 34, a cutting motor 35 and a cutter 36. The cutting mechanism is located at the left position in the middle of the base as a whole, and the length of the polyurethane insulation pipe between the cutter and the mounting plate is the required length of the finished polyurethane insulation pipe. The fixed plates 31 are two symmetrically distributed front and back, and the crossbeam 32 is arranged between the two fixed plates 31 extending front and back, and the two are integrally formed; the bottom end of the fixed plate and the base can be fixed by bolt connection or direct welding. The first cylinder 33 is vertically distributed on the crossbeam 32, and the bottom end is connected to the mounting seat 34; an air pump is arranged on one side of the crossbeam for connecting and controlling the movement of the cylinder. The cutter 36 is connected and installed on the mounting seat 34 through a rotating shaft 37, and the cutting motor 35 is fixedly installed on the mounting seat 34 through a bracket and connected to the rotating shaft 37. With such a configuration, the start of the cutting motor will drive the rotating shaft and the cutter to move synchronously, and under the telescopic action of the cylinder, the preset height is lowered, that is, the cutter cuts the insulation pipe. In this embodiment, the optimized length adjustment and clamping synchronous rotation structure not only ensure the efficiency of the effective and complete cutting of the insulation pipe, but also a simple and small cutting cutter can be used to lower a small height to complete the complete cutting of the insulation pipe, which greatly reduces the production cost and is more cost-effective.

[0026] like Figure 1 and Figure 5As shown: In this embodiment, the adjustment mechanism 4 includes a positioning plate 41, a moving part 42 and a clamping part 43. The positioning plate 41 is arranged on the base 1 and is located on the right side of the cutter 36. The center of the positioning plate 41 is consistent with the center of the polyurethane insulation pipe; the moving part 42 is used to drive the positioning plate 41 to move left and right relative to the base 1 to complete the cutting operation of the polyurethane insulation pipe of a preset length. In a preferred technical solution, the moving part 42 includes an axial slide rail 421, an axial slider 422, an axial fixing block 423, an axial screw rod 424, a side wing plate 425 and an axial motor 426. The axial slide rail 421 is arranged on the base 1 in a left-right distribution, and the axial slide rail can also be fastened to the end face of the base by screws. Correspondingly, a scale line extending left and right can also be set at the base corresponding to the axial slide rail for distance observation. The axial slider 422 is arranged on the positioning plate 41 and is matched with the axial slide rail 421; the axial slider and the positioning plate can be fixed by welding. The axial fixing block 423 is arranged at the bottom center of the positioning plate 41, and the side wing plates 425 are two and are distributed on the left and right sides. The axial screw rod 424 is arranged between the two side wing plates 425 and is connected to the axial motor 426 at one end. The axial motor 426 is fixedly installed on the right side of the base 1 through a bracket; wherein, the axial motor also adopts a servo control motor, the purpose of which is to accurately control the moving position of the positioning plate, thereby ensuring the accuracy of the cutting length of the insulation pipe. The axial screw rod 424 is threadedly connected to the axial fixing block 423. In this way, the axial slider cooperates with the axial slide rail to form a good auxiliary guiding effect. Then, when the axial motor starts to rotate forward, it will drive the axial screw rod to rotate clockwise, and a screw nut structure will be formed between the axial screw rod and the axial fixing block, that is, the clockwise rotation of the axial screw rod will drive the axial fixing block and the positioning plate to move to the left as a whole, and at this time, the polyurethane insulation pipe is cut to a shorter finished insulation pipe. When the axial motor starts to reverse, it will drive the axial screw to rotate counterclockwise, that is, the axial screw will drive the axial fixing block and the positioning plate to move to the right as a whole. At this time, it corresponds to the demand for cutting longer finished polyurethane insulation pipes.

[0027] like Figure 5As shown: In this embodiment, the positioning plate 41 includes a base plate 411 and a movable plate 412. A guide rod 413, a rotating lead screw 414 and a rotating handle 415 are also provided between the base plate 411 and the movable plate 412. Among them, the base plate 411 extends forward and backward, and the axial slider 422 is fixedly installed on the base plate 411. The guide rod 413 is vertically distributed and arranged on the rear side of the base plate 411, and the bottom end of the guide rod and the base plate can be fixed by welding. The rotating lead screw 414 is vertically distributed and rotatably arranged on the front side of the base plate 411, and the rotating lead screw and the base plate can be connected by a bearing to maintain relative rotation and non-relative movement. The movable plate 412 is arranged above the base plate 411, and is distributed through the guide rod 413 and the rotating lead screw 414. Among them, the movable plate 412 and the guide rod 413 are maintained in sliding connection, and the movable plate 412 and the rotating lead screw 414 are maintained in threaded connection; the rotating handle 415 is arranged at the top of the rotating lead screw 414. With this arrangement, the guide rod plays an auxiliary guiding role. By rotating the handle, the synchronous rotation of the screw can be achieved, which will drive the upward and downward movement of the movable plate. The purpose of this arrangement is to adjust the position of the mounting plate on the movable plate accordingly. Since the support rollers distributed on the left side are away from or close to each other to adapt to the support requirements of polyurethane insulation pipes of different diameters and sizes, that is, the central axis heights of polyurethane insulation pipes of different sizes are different. The corresponding right side can ensure that the center of the mounting plate is consistent with the polyurethane insulation pipe by adjusting the vertical height position of the movable plate, thereby providing favorable conditions for subsequent center clamping and rotary cutting movements.

[0028] like Figure 2 and Figure 6 As shown: In this embodiment, the clamping member 43 is used to complete the clamping operation of the end of the polyurethane thermal insulation pipe and drive the polyurethane thermal insulation pipe to rotate synchronously when the cutter 36 is operating. Specifically, the clamping member 43 includes a mounting plate 431, a driving plate 432, a driving shaft 433 and a driving motor 434. The driving shaft 433 is arranged on the movable plate 412 in a left-right distribution, and the driving motor 434 is arranged on the movable plate 412 through a bracket, and the output shaft is connected to the driving shaft 433; wherein, the driving motor can also be a servo-controlled motor. The mounting plate 431 is a cylindrical structure, and the interior is hollow. The right end of the mounting plate 431 is connected to the driving shaft 433 through a bearing, and the left end face is also provided with an arc groove 436. For details, refer to Figure 7As shown. When the clamping rod is at the outermost end of the arc groove, it is in the initial state; the forward rotation of the driving motor will drive the driving plate to rotate counterclockwise, and the corresponding clamping rod will move inward along the arc groove, forming a clamping operation on the centrally distributed polyurethane thermal insulation pipe. The driving plate 432 is also circular and is installed inside the mounting plate 431. The driving plate 432 is fixedly connected to the driving shaft 433. A clamping rod 437 is also provided on the driving plate 432, and the clamping rod 437 passes through the arc groove 436 to the left. The mounting plate 431 and the driving plate 432 are concentrically arranged with the polyurethane thermal insulation pipe. The clamping rod 437 and the arc groove 436 are any of three, four, five, six, etc. groups that are matched and evenly distributed in an annular shape. Please refer to the specific Figure 7 and Figure 8 The structure shown, Figure 7 The dotted line indicates the maximum outer diameter of the polyurethane insulation pipe that can be cut and clamped.

[0029] With this arrangement, when the staff adjusts the distance between the cutter and the mounting plate to a preset length, the right end of the polyurethane insulation pipe moves through an external conveying device to contact the left end face of the mounting plate. In the initial state, the clamping rod is on the outside of the arc groove. At this time, the right end of the insulation pipe is in tight contact with the mounting plate, providing sufficient friction. Then the staff starts the drive motor. The forward rotation of the drive motor will drive the drive plate to rotate counterclockwise, and the corresponding clamping rod will move inward along the arc groove of the mounting plate, forming a clamping operation for the centrally distributed polyurethane insulation pipe. At this time, the insulation pipe, the mounting plate and the drive plate form an integrated structure. The continued forward rotation of the drive motor will drive the insulation pipe to rotate synchronously, thereby achieving a circular motion of the insulation pipe to complete an efficient cutting operation. At the same time, the clamping structure of the mounting plate, drive plate, drive shaft and drive motor is combined with the moving part structure for axial movement adjustment. The spatial structure is compact, which not only ensures the stability of the clamping and rotation of the polyurethane insulation pipe, but also can realize the cutting of finished pipes with different length requirements. The simple structure can achieve uniform cutting of larger specifications of polyurethane insulation pipes, effectively prolonging the service life of the cutter and greatly improving the accuracy of the cutting end of the insulation pipe.

[0030] like Figure 1As shown: In this embodiment, a finished product collection box 5 is also provided on the front side of the base 1, and an inclined conveying surface 6 is also provided on the base 1 on the right side of the cutter 36 and the left side of the mounting plate 431, and the lower side of the conveying surface 6 is close to the finished product collection box 5. Specifically, a through hole is provided on the base, and the conveying surface is arranged at the through hole in an inclined manner to guide the delivery of the finished insulation pipe to be dropped. Correspondingly, in order to ensure the accuracy of the position of the finished product collection box, a connecting piece can be provided between the base and the finished product collection box, and the connecting piece can preferably adopt a matching installation structure of a strong magnet sub-block and a strong magnet mother block. When the insulation pipe rotates one circle, the cutter can complete the complete cutting of the insulation pipe. While the cutting efficiency is high, it also effectively protects the safe use of the cutter, and further improves the service life of the cutter. After the insulation pipe completes the cutting of the preset length, the reverse rotation of the driving motor will cause the clamping rod to move outward along the arc groove to complete the unlocking operation of the insulation pipe. At this time, the axial motor reverses one circle, driving the mounting plate and the positioning plate to move right by a preset distance (a relatively small distance of 1-3cm) as a whole to complete the release of the finished insulation pipe. The finished insulation pipe after cutting will automatically fall and slide along the conveying surface 6 into the finished product collection box. When the storage of the finished product collection box reaches the preset amount, the staff will move and pull out and replace the corresponding new finished product collection box.
