Description

Technical Field

[0001] The present invention relates to the technical field of engineering part cutting, in particular to a laser cutting device for processing engineering plastic parts. Background Art

[0002] Engineering plastics can be used as engineering materials and as plastics to replace metal in the manufacture of machine parts. They have excellent comprehensive properties, such as high rigidity, low creep, high mechanical strength, good heat resistance, and good electrical insulation. They can be used for long periods of time in harsh chemical and physical environments and can replace metal as engineering structural materials. Engineering plastic pipes are one of the most commonly used engineering accessories. They refer to pipes made of plastic materials and are usually used for fluid transportation and drainage in various engineering and construction applications. Before they are put into use, engineering plastic pipes are usually cut to length using a pipe laser cutting machine. Pipe laser cutting machines are mostly used to cut various hollow circular tubes made of non-metallic solid materials, such as plastic pipes, PVC pipes, PVB pipes and other industrial and civil materials.

[0003] Existing patent CN219310367U discloses a pipe laser cutting device. Through the coordinated use of the transport component, cutting component, and rotating component on the top of the base, the pipe laser cutting device can directly fix pipes of different diameters, reducing the time required for cutting pipes during the production process.

[0004] The above-mentioned equipment can only realize the adaptive fixing function for different pipes. However, in the specific laser cutting process of the pipe body, due to the light weight of the plastic pipe fitting itself, only the single-side clamping limit of the cutting section of the pipe body is provided, which can easily cause the plastic pipe fitting to shift or incomplete cutting due to uneven force on the plastic pipe body, thereby affecting the cutting quality of the plastic pipe fitting; at the same time, due to the material limitation of the plastic pipe fitting itself, after the outside is laser cut, the cutting area of the plastic pipe fitting is heated, resulting in a temporary heating and softening of the edge of the cutting surface of the pipe mouth, thereby increasing the risk of difficulty in completely separating the pipe bodies or sticking together during cutting, thereby affecting the cutting efficiency of the plastic pipe fitting.

[0005] In view of the technical defects in this aspect, a solution is now proposed. Summary of the Invention

[0006] The purpose of the present invention is to clamp the plastic tube in sections and cut it to a fixed length on the basis of adaptive pressure limiting of the entire tube body, so as to ensure that the plastic main tube and the cut branch tube are kept in a stable state, thereby reducing the deviation of the plastic tube and affecting the cutting quality. At the same time, the cut surface of the tube body is further divided to avoid the sticking between the tube bodies due to the high temperature of laser cutting, thereby improving the processing efficiency of the plastic tube.

[0009] Furthermore, the steering cutting assembly includes a limit plate, which is arranged at the middle and upper end of the inner wall of one side of the segmented frame, and the limit plate penetrates and is rotatably connected to the limit cylinder away from one end of the segmented frame, and the upper and lower ends of the limit cylinder extend to the outside of the limit plate, and a laser cutter is horizontally penetrated by one side of the limit cylinder near the bottom cylinder mouth, and the end of the laser cutter extends into the limit cylinder, and a driven gear ring is fixedly sleeved at the top cylinder mouth of the limit cylinder.

[0010] Furthermore, a motor is provided on the bottom surface of the limiting plate adjacent to the limiting cylinder, and the output end of the motor extends to the upper end of the limiting plate and is fixedly mounted with a driving gear, which is engaged with the driven gear ring.

[0011] Furthermore, the upper and lower end surfaces of the segmented frame are respectively provided with rectangular inner grooves, and the interior of the upper rectangular inner groove is slidingly connected to a clamp frame 1 at the front and rear ends respectively, and the interior of the lower rectangular inner groove is slidingly connected to a clamp frame 2 at the front and rear ends respectively, and the two groups of the clamp frames 2 and one end of a pair of opposite surfaces of the two groups of the clamp frames are both provided with an oblique groove 1, and the two adjacent groups of the oblique grooves 1 are mirror-symmetrical.

[0012] Furthermore, a movable frame with a concave structure is movably connected between the upper and lower groups of clamping frames 1 and 2 and located on one side. A cylinder 2 is provided between the side of the movable frame away from the opening and the inner wall of the corresponding segmented frame through a push rod, and a sliding shaft 1 is fixedly installed on the upper and lower end surfaces of the movable frame at the opening side. The four groups of sliding shafts 1 are respectively slidably connected to the corresponding inclined grooves.

[0013] Furthermore, the two groups of the clamping frames are provided with hollow grooves near both sides of the center, and side support plates are provided between the two groups of hollow grooves opposite to each other. The front and rear ends of the left and right groups of side support plates are respectively slidably connected to the inside of the sliding grooves provided on the front and rear inner walls of the rectangular inner groove. The left and right groups of side support plates are mirror-symmetrical with respect to the central axis of the segmented frame.

DETAILED DESCRIPTION

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0028] Example 1:

[0029] See also Figure 1 - Figure 7 As shown, a laser cutting device for processing engineering plastic parts includes an operating frame 1, a top plate 2 is movably mounted on the top of the operating frame 1, and four groups of vertical rods 3 with inverted T-shaped structures are penetrated at the corners of the top plate 2, the tops of the four groups of vertical rods 3 are fixedly connected to the top inner wall of the operating frame 1, and the outsides of the vertical rods 3 located at the upper ends of the top plate 2 are wound with spring coils 4. First, a single group of plastic pipe fittings for engineering use is vertically inserted into the operating frame 1, and the top ends of the plastic pipe fittings press upward against the top plate 2. The bottom of the top plate 2 is pressed and penetrates the four groups of vertical rods 3 respectively and presses against the spring coils 4 for compression. The top plate 2 rises to a suitable height until it adaptively presses against the plastic pipe fittings to achieve preliminary definition of the plastic pipe fittings.

[0030] The operating frame 1 is internally provided with a segmented cutting mechanism 5 at the bottom end thereof. The segmented cutting mechanism 5 comprises a segmented frame 51 of a circular structure. The segmented frame 51 is slidably connected to the bottom end of the operating frame 1, and a sliding frame 52 is fixedly installed on both sides of the segmented frame 51. The two sets of sliding frames 52 are respectively sleeved on the two side frames of the operating frame 1. The top surfaces of the two sets of sliding frames 52 are jointly fixed with an inverted concave push frame 53, and a cylinder 54 is provided between the top inner wall of the push frame 53 and the top surface of the operating frame 1 through a push rod. The upper and lower end surfaces of the segmented frame 51 are respectively provided with rectangular inner grooves 55; a steering cutting assembly 6 is provided on the inner wall of one side of the segmented frame 51, and the steering cutting assembly 6 includes a limit plate 61. The positioning plate 61 is arranged at the middle upper end of the inner wall of one side of the segment frame 51, and the limiting plate 61 is penetrated and rotatably connected to the limiting cylinder 62 at one end away from the segment frame 51. The upper and lower ends of the limiting cylinder 62 extend to the outside of the limiting plate 61. A laser cutter 63 is horizontally penetrated at one side of the limiting cylinder 62 near the bottom cylinder opening, and the end of the laser cutter 63 extends into the limiting cylinder 62. A driven gear ring 64 is fixedly sleeved at the top cylinder opening of the limiting cylinder 62. A motor 65 is provided on the bottom surface of the limiting plate 61 adjacent to the limiting cylinder 62, and the top output end of the motor 65 extends to the upper end of the limiting plate 61 and is fixedly installed with a driving gear 66, which meshes with the driven gear ring 64.

[0031] In the initial limited state of the plastic pipe fitting, the bottom of the plastic pipe fitting passes through the interior of the segmented frame 51, and the section of the bottom tube body passes through the interior of the limiting cylinder 62. The laser cutter 63 is then used to laser cut the plastic pipe fitting section that passes through the interior of the limiting cylinder 62 (the plastic pipe fitting section that is flush with the cutting head of the laser cutter 63). During cutting, the motor 65 is started to drive the driving gear 66 to rotate clockwise, and the driving gear 66 is engaged with the driven gear ring 64, forcing the driven gear ring 64 and the limiting cylinder 62 to rotate counterclockwise synchronously. The laser cutter 63 performs a circular motion with the limiting cylinder 62, which can achieve circumferential cutting of the outer wall of the plastic pipe fitting without rotating the plastic pipe fitting, thereby reducing the wear of the outer wall of the plastic pipe fitting.

[0032] After the fixed-length cutting of the bottom pipe body is completed, the cylinder 1 54 is activated, and the push frame 53 is pulled upward by the push rod, and the bottom of the push frame 53 is pulled upward by the two sets of sliding frames 52 until the steering cutting assembly 6 moves to the next cutting point. Then the above cutting steps are repeated to achieve the same length of pipe cutting;

[0033] Therefore, this structure can not only provide preliminary adaptive limited clamping for plastic pipe fittings, but also perform segmented, sealed, and rotary cutting of plastic pipe fittings. On the basis of ensuring uniform segmented cutting of plastic pipe fittings, it also reduces the probability of injury to personnel during operation and improves the laser cutting efficiency of plastic pipe fittings.

[0034] Example 2:

[0035] See also Figure 3 、 Figure 5 - Figure 7 As shown, the interior of the upper rectangular inner groove 55 is slidably connected to a clamping frame 1 56 at the front and rear ends respectively, and the interior of the lower rectangular inner groove 55 is slidably connected to a clamping frame 2 57 at the front and rear ends respectively. An inclined groove 1 58 is provided at one end of the two groups of clamping frames 2 57 and the opposite sides of the two groups of clamping frames 1 56. The two adjacent groups of inclined grooves 1 58 are mirror-symmetrical. A movable frame 59 with a concave structure is movably connected between the upper and lower groups of clamping frames 1 56 and the clamping frame 2 57 and located on one side. A cylinder 2 591 is provided between the side of the movable frame 59 away from the opening and the corresponding inner wall of the segmented frame 51 through a push rod, and a sliding shaft 1 510 is fixedly installed on the upper and lower end surfaces of the movable frame 59 at the opening side. The four groups of sliding shafts 1 510 are slidably connected to the corresponding inclined groove 1 58 respectively.

[0036] When cutting the plastic pipe to a fixed length, in order to maintain the stability of the uncut pipe, the second cylinder 591 is activated, and the push rod is used to push the movable frame 59 to move linearly. The sliding shafts 510 on the upper and lower end surfaces of the movable frame 59 move linearly along the corresponding inclined groove 58, forcing the inner wall of the inclined groove 58 to resist. In this way, the front and rear clamping frames 56 and the front and rear clamping frames 57 are respectively moved closer to each other and respectively clamp the outer wall of the plastic pipe in multiple sections, thereby further maintaining the stability of the plastic pipe.

[0037] It is worth noting that the steering cutting assembly 6 is located between the clamping frame 1 56 and the clamping frame 2 57. Therefore, during the cutting process, the two sets of clamping frames 1 56 and clamping frames 2 57 respectively clamp the upper and lower ends of the pipe cutting point to maintain the stability of the cut section of the pipe body to avoid the pipe body from being offset due to uneven force during cutting, thereby reducing the cutting effect of the pipe body.

[0038] Example 3:

[0039] After the laser cutter 63 cuts the tube, the temperature of the plastic tube surface at the cut section increases, and some plastic tubes temporarily heat up and soften at the edges as the temperature rises, which can easily cause the plastic tubes in the cut section to stick together, thereby affecting the segmented cutting quality of the plastic tube.

[0040] See also Figure 6 - Figure 7The two sets of side plates 511 are respectively slidably connected to the inner grooves provided on the front and rear inner walls of the rectangular inner groove 55. The left and right sets of side plates 511 are mirror-symmetrical with respect to the central axis of the segmented frame 51. Semicircular thin slices 512 are fixedly installed at the centers of the opposite surfaces of the two sets of clamping frames 57 and the centers of the opposite sides of the two sets of side plates 511. A long groove 513 is provided at the center of the top surface of each set of side plates 511, and a second inclined groove 514 is fixedly installed at the front and rear ends of the long groove 513. The two sets of second inclined grooves 514 are mirror-symmetrical with respect to the central axis of the long groove 513, and a second sliding shaft 515 is slidably connected to the end of the second inclined groove 514 away from the long groove 513. The top of the second sliding shaft 515 is fixedly connected to the inner wall of the top of the corresponding hollow groove.

[0041] During the process of continuously cutting the pipe in sections and changing the cutting section position, the clamping frame 1 56 rises and moves to the upper end position of the next cutting point, and the clamping frame 2 57 moves to the previous cutting line in sequence. At this time, the above clamping steps are repeated;

[0042] When clamping again, the front and rear two groups of clamping frames 57 are close to each other, forcing the semicircular thin slices 512 on the opposite sides thereof to be inserted into the front and rear ends of the cutting line at the same height respectively. At the same time, as the front and rear two groups of clamping frames 57 are close to each other, they respectively move relative to the two groups of side abutment plates 511, and the sliding shaft 515 moves with the clamping frame 57 and moves along the corresponding inclined groove 514. The inner wall of the inclined groove 514 is abutted, causing the side abutment plates 511 to move linearly. Therefore, the left and right groups of side abutment plates 511 are close to each other, and the semicircular thin slices 512 on the opposite sides thereof are respectively inserted into the front and rear ends of the cutting line at the same height. The four groups of semicircular thin slices 512 are respectively inserted into the gaps between the upper and lower groups of pipe bodies that have been cut and separated, further assisting the separation of the cut plastic pipe parts and reducing the sticking between the cut pipe bodies. At the same time, after the bottom pipe body is separated, the bottom support of the plastic pipe section to be cut can be provided, thereby increasing the stability of the pipe body.

[0043] The structure can further separate the cut section of the plastic pipe body, reduce the adhesion between the plastic pipe fittings in the cut section, and improve the cutting quality of the plastic pipe fittings.

[0044] Working principle:

[0045] When the present invention is used, firstly, a single set of plastic pipe fittings for engineering is vertically inserted into the operating frame 1, and the top of the plastic pipe fitting presses upward against the top plate 2. The bottom of the top plate 2 is pressed and passes through the four sets of vertical rods 3 respectively and presses against the spring coils 4 for compression. The top plate 2 rises to a suitable height until it adaptively presses against the plastic pipe fitting.

[0046] Next, a portion of the plastic pipe is passed through the interior of the limiting cylinder 62. Then, the second cylinder 591 is activated, and the push rod is used to push the movable frame 59 to move linearly. The sliding shafts 1 510 on the upper and lower end surfaces of the movable frame 59 move linearly along the interior of the corresponding inclined groove 1 58, forcing the inner wall of the inclined groove 1 58 to be pressed. In this way, the front and rear clamping frames 1 56 and the front and rear clamping frames 2 57 are respectively moved closer to each other and respectively clamp the outer wall of the plastic pipe in multiple sections.

[0047] Then, the plastic pipe section is cut to a fixed length, and the cylinder 2 591 is started to push the movable frame 59 to move linearly, and the sliding shaft 1 510 on the upper and lower end surfaces of the movable frame 59 moves linearly along the corresponding inclined groove 1 58, forcing the inner wall of the inclined groove 1 58 to be resisted, so that the front and rear two groups of clamping frames 1 56 and the front and rear two groups of clamping frames 2 57 are close to each other, and the steering cutting assembly 6 is located between the clamping frame 1 56 and the clamping frame 2 57, and the two clamp the upper and lower ends of the cutting point of the pipe fitting respectively to keep the pipe body of the cut section stable; then the laser cutter 63 is used to laser cut the plastic pipe section passing through the interior of the limiting cylinder 62, and the motor 65 is started to drive the driving gear 66 to rotate clockwise, and the driving gear 66 is engaged with the driven gear ring 64 to force the driven gear ring 64 and the limiting cylinder 62 to rotate counterclockwise synchronously, and the laser cutter 63 performs a circular motion with the limiting cylinder 62 to cut the outer wall of the plastic pipe fitting;

[0048] Finally, after the fixed-length cutting is completed, the cylinder 1 54 is started and the push frame 53 is pulled upward by the push rod, and the bottom of the push frame 53 is pulled upward by the two sets of sliding frames 52 to pull the segment frame 51 and the steering cutting assembly 6 until the steering cutting assembly 6 moves to the next cutting point, and then the above cutting steps are repeated to achieve the same length of pipe cutting.
