Description

Technical Field

[0001] The 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 plastics that replace metals to manufacture machine parts. Engineering plastics have excellent comprehensive properties, high rigidity, low creep, high mechanical strength, good heat resistance, good electrical insulation, and can be used for a long time in harsh chemical and physical environments. They can replace metals as engineering structural materials. Engineering plastic pipes are one of the most commonly used engineering accessories. They refer to pipes made of plastic materials. They are usually used for fluid transportation and drainage in various projects and buildings. Before the engineering plastic pipes are put into use, they are usually cut to length using a pipe laser cutting machine. Pipe laser cutting machines are mostly used to cut various hollow round tube materials of non-metallic solid materials, such as plastic pipes, PVC pipes, PVB pipes and other industrial and civil materials.

[0003] The existing patent CN219310367U discloses a tube laser cutting device. Through the cooperation between the transport component, the cutting component and the rotating component on the top of the base, the tube laser cutting device can directly fix tubes of different diameters, thereby reducing the time required for cutting the tubes during the production and processing process.

[0004] The above-mentioned equipment can only realize the adaptive fixing function for different pipes. However, in the specific process of laser cutting of the pipe body, due to the light weight of the plastic pipe fittings themselves, only the cutting section of the pipe body is clamped on one side, which may cause the plastic pipe fittings to shift or incompletely cut due to uneven force on the plastic pipe body, thereby affecting the cutting quality of the plastic pipe fittings. At the same time, due to the material limitations of the plastic pipe fittings themselves, after the outside is laser cut, the cutting area of ​​the plastic pipe fittings is heated, resulting in a brief heating and softening of the edge of the cutting surface of the pipe mouth, thereby increasing the risk of difficulty in completely separating or sticking between the pipe bodies during cutting, thereby affecting the cutting efficiency of the plastic pipe fittings.

[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 pipe in sections and cut it to a fixed length on the basis of the overall adaptive pressure limit of the pipe body, so as to ensure that the plastic main pipe and the cut branch pipe remain in a stable state, thereby reducing the deviation of the plastic pipe and affecting the cutting quality. At the same time, the cut surface of the pipe body is further divided to avoid the sticking of the pipe body due to the high temperature of laser cutting, thereby improving the processing efficiency of the plastic pipe.

[0012] Furthermore, a movable frame with a concave structure is movably connected between the upper and lower groups of clamp frames 1 and 2 and located on one side. A cylinder 2 is arranged between a side of the movable frame away from the opening and an inner wall of the corresponding segmented frame through a push rod. 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 abutment plates are provided between the two groups of hollow grooves opposite to each other.

DETAILED DESCRIPTION

[0027] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than 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.

[0028] Embodiment 1:

[0029] See also Figure 1 - Figure 7 As shown, a laser cutting device for processing engineering plastic parts comprises an operating frame 1, a top plate 2 is movably mounted on the top of the operating frame 1, and four groups of corners of the top plate 2 are penetrated by vertical poles 3 with an inverted T-shaped structure, the tops of the four groups of vertical poles 3 are fixedly connected to the inner wall of the top of the operating frame 1, and the outsides of the vertical poles 3 are located at the upper ends of the top plate 2 and are wound with spring coils 4, firstly, a single group of plastic pipe fittings for engineering 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 poles 3 respectively and presses against the spring coils 4 for compression, and the top plate 2 rises to a suitable height until it is adaptively pressed against the plastic pipe fittings, so as to achieve preliminary definition of the plastic pipe fittings;

[0030] A segmented cutting mechanism 5 is movably arranged at the bottom end inside the operating frame 1. The segmented cutting mechanism 5 includes a segmented frame 51 of a circular structure. The segmented frame 51 is slidably connected to the bottom end inside the operating frame 1, and sliding frames 52 are fixedly installed on both sides of the segmented frame 51. Two groups of sliding frames 52 are respectively sleeved on the two side frames of the operating frame 1. An inverted concave push frame 53 is fixedly installed on the top surface of the two groups of slide frames 52. A cylinder 54 is arranged between the top inner wall of the push frame 53 and the top surface of the operating frame 1 through a push rod. Rectangular inner grooves 55 are respectively arranged on the upper and lower end surfaces of the segmented frame 51; a steering cutting assembly 6 is arranged on the inner wall of one side of the segmented frame 51, and the steering cutting assembly 6 includes a limiting 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 end of the positioning plate 61 away from the segment frame 51 penetrates and is rotatably connected to the limiting cylinder 62, the upper and lower ends of the limiting cylinder 62 both extend to the outside of the positioning plate 61, a laser cutter 63 is horizontally penetrated at one side of the limiting cylinder 62 near the bottom cylinder mouth, 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 mouth of the limiting cylinder 62, a motor 65 is arranged at the bottom surface of the positioning plate 61 adjacent to the limiting cylinder 62, and the top output end of the motor 65 extends to the upper end of the positioning plate 61 and is fixedly installed with a driving gear 66, and the driving gear 66 is meshed with the driven gear ring 64;

[0031] When the plastic pipe is initially limited, the bottom of the plastic pipe runs through the segment frame 51, and the section of the bottom tube body runs through the limiting cylinder 62. The laser cutter 63 is then used to laser cut the plastic pipe section that runs through the limiting cylinder 62 (the plastic pipe section 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 meshed with the driven gear ring 64 to force the driven gear ring 64 and the limiting cylinder 62 to rotate counterclockwise synchronously. The laser cutter 63 moves in a circle with the limiting cylinder 62, which can realize circumferential cutting of the outer wall of the plastic pipe without rotating the plastic pipe, thereby reducing the wear of the outer wall of the plastic pipe.

[0032] After the fixed-length cutting of the bottom pipe body 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 together to pull the segmentation 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;

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

[0034] Embodiment 2:

[0035] See also Figure 3 , Figure 5 - Figure 7 As shown, the upper rectangular inner groove 55 is slidably connected with a clamping frame 1 56 at the front and rear ends, and the lower rectangular inner groove 55 is slidably connected with a clamping frame 2 57 at the front and rear ends. The two groups of clamping frames 2 57 and one end of the opposite sides of the two groups of clamping frames 1 56 are both provided with an inclined groove 1 58. 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. The upper and lower end surfaces of the movable frame 59 are fixedly installed with a sliding shaft 1 510 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 the plastic pipe is cut to a fixed length, in order to maintain the stability of the uncut pipe body, the second cylinder 591 is started and the push rod is used to push the movable frame 59 to move linearly, and the sliding shafts 1 510 on the upper and lower end surfaces of the movable frame 59 move linearly along the corresponding inclined groove 1 58, respectively, and force 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 respectively close to each other, and respectively clamp the outer wall of the plastic pipe in multiple sections, so as to further maintain the stability of the plastic pipe;

[0037] It is worth mentioning that the steering cutting assembly 6 is located between the clamp frame 1 56 and the clamp frame 2 57. Therefore, during the cutting process, the two sets of clamp frames 1 56 and the clamp frame 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 on the pipe body during cutting, thereby reducing the cutting effect of the pipe body.

[0038] Embodiment three:

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

[0040] See also Figure 6 - Figure 7As shown, the two groups of second clamping frames 57 are provided with hollow grooves near both sides at the center, and a side abutment plate 511 is 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 abutment plates 511 are respectively slidably connected to the inside of the sliding grooves provided on the front and rear inner walls of the rectangular inner groove 55. The left and right groups of side abutment 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 groups of second clamping frames 57 and the centers of the opposite surfaces of the two groups of side abutment plates 511. A long groove 513 is provided at the center of the top surface of each group of side abutment plates 511, and a second inclined groove 514 is fixedly installed at the front and rear ends of the long groove 513. The two groups 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, and the top of the second sliding shaft 515 is fixedly connected to the corresponding inner wall of the top of the hollow groove.

[0041] In the process of continuously cutting the pipe in sections and changing the position of the cutting section, 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 approach each other, forcing the semicircular thin slices 512 on the opposite sides of the two to be inserted into the front and rear ends of the cutting line at the same height. At the same time, as the front and rear two groups of clamping frames 57 approach each other, the two groups of side abutment plates 511 move relative to each other, 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 plate 511 to move linearly. Therefore, the left and right groups of side abutment plates 511 approach each other, and the semicircular thin slices 512 on the opposite sides of the two 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 intervals between the upper and lower groups of pipe bodies that have been cut and separated, further assisting the separation of the cut plastic pipes 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 cut the cut section of the plastic pipe body, reduce the sticking 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 fittings presses upward against the top plate 2, the bottom of the top plate 2 is pressed and penetrates through the four sets of vertical rods 3 respectively and presses against the spring group coil 4 for compression, and the top plate 2 rises to a suitable height until it is adaptively pressed against the plastic pipe fittings;

[0046] Next, a portion of the plastic pipe is passed through the inside of the limiting cylinder 62, and then the air cylinder 591 is started, and the push rod is used to push the movable frame 59 to move linearly, and the sliding shaft 510 on the upper and lower end surfaces of the movable frame 59 moves linearly along the inside of the corresponding inclined groove 58, respectively, and the inner wall of the inclined groove 58 is forced 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 respectively close to each other and 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, respectively, and forces 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 stability of the cut section pipe body; then the laser cutter 63 is used to laser cut the plastic pipe section that passes through the inside 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 meshed 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 moves in a circle 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 rod is used to pull the push frame 53 upward, and the bottom of the push frame 53 is pulled upward by the two sets of sliding frames 52 to pull the segmentation 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.
