Description

Technical field:

[0002] The utility model relates to a mechanism used in a processing device, in particular to a lining pipe fitting laser blanking mechanism. The lining pipe fitting can be a polytetrafluoroethylene lining pipe fitting (that is, a pipe made of polytetrafluoroethylene). The device serves as an auxiliary mechanism during laser processing of polytetrafluoroethylene lining pipe fittings. Background technology:

[0004] Laser cutting machines are often used for cutting workpieces. For some tubes and rods, laser cutting machines are like grinding wheel cutting machines, but the tooling or discharge mechanism of grinding wheel cutting machines cannot be applied to laser cutting machines. Usually, when grinding wheel cutting machines cut tubes, they only need to clamp one end before cutting, which is not applicable to laser cutting machines.

[0005] Lined pipe fittings (including polytetrafluoroethylene lined pipe fittings) have high requirements for dimensional accuracy. The use of abrasive wheel cutting machines is prone to produce shavings and poor clamping support stability and reliability, which can easily affect the quality of the finished product.

[0006] A Chinese patent "A laser blanking mechanism with a slag removal structure" was retrieved, with announcement number CN219900688U, which includes a fixed frame, a hollow rod, a clamping mechanism, a laser cutting mechanism and a pipe. The top outer surface of the fixed frame is laterally slidably installed with a hollow rod; the laser blanking mechanism with a slag removal structure, when in use, the laser blanking mechanism with a slag removal structure is provided with a hollow tube, a dust collecting hole, a hollow disk, a hollow rod, a dust collecting bag, a vacuum cleaner and a stretch hose, so that when the slag is removed, the hollow tube can be inserted into one end of the cut pipe as a whole, and the dust collecting hole is aligned with the bottom side of the cutting head of the laser cutting mechanism, so that the whole can effectively collect the spark sediment ejected by the cutting in time during cutting, and then after the overall cutting is completed, the vacuum cleaner can be used to absorb and collect the sediment dust in the dust collecting hole, and the overall slag removal and collection effect is good, reducing the splashing of sediment dust.

[0007] Although the above-mentioned existing patent has good overall slag removal and collection effect and can reduce the splashing of sediment and dust, it cannot support the free end according to the length of the processed pipe and rod, and cannot meet higher processing requirements.

[0029] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0030] The utility model provides a liner pipe fitting laser blanking mechanism, comprising a laser processing device 1, specifically a laser cutting device, wherein the laser processing device 1 comprises a main body 2 capable of emitting laser vertically, wherein the main body 2 can be in at least a vertical direction (such as Figure 1vertical direction), radial direction (such as Figure 1 The above is existing equipment, and the specific work will not be repeated.

[0031] A material receiving platform 3 is provided below the main body 2, and the material receiving platform 3 includes two parallel side walls 4 arranged at high and low intervals. A plurality of parallel support bars 5 arranged at intervals are detachably connected to the upper parts of the two side walls, and the support bars 5 and the lining pipe fittings A to be processed are perpendicular to each other in space; among the two side walls 4, the higher side wall is arranged on the inner side, and the lower side wall is arranged on the outer side, and the two ends of the support bars 5 are respectively supported on the two side walls 4, so that the support bars 5 are inclined, and the slope is 5-10 degrees.

[0032] Specifically, the support bar 5 includes a rectangular sheet 501 and an inclined sheet body 502 arranged on one long side of the rectangular sheet, the inclined sheet body 502 forms a 120-170 degree angle with the rectangular sheet 501, and the end of the rectangular sheet is provided with a bending portion 503, which can be embedded in the notch 12 on the upper part of the side wall. On the side wall on the same side, the spacing between two adjacent notches 12 is greater than the width of one support bar 5, but less than the width of two support bars 5; the bending portion 503 and the notch 12 are connected with a gap or transition fit, so that the support bar 5 can be easily installed into the notch 12, the length of the inclined sheet body is shorter than that of the rectangular sheet, and the end of the inclined sheet body is close to the inner side of the side wall, the inclined sheet body can guide the debris dropped on it into the aisle, and the support bar 5 can be stamped from a metal plate; if the two side walls are flush and paved by a flat plate, the blanking cannot be easily rolled down, and the debris cannot be discharged.

[0033] An aisle 6 is formed between the two side walls, and a slide rail 7 is provided at the bottom of the aisle. The slide rail is provided with a support seat 8 that can slide along the length direction of the slide rail. The cross-section of the slide rail 7 can be T-shaped, and the support seat 8 slides in cooperation with the T-shaped slide rail 7. The bottom surface of the support seat 8 is also processed with a slide groove for the T-shaped slide rail 7. The slide groove transitions with the slide rail 7, which is conducive to stable sliding and can prevent debris from entering the slide groove.

[0034] A lift platform 9 is provided on the support seat 8, on which a replaceable support block 10 for supporting the first end of the material to be processed is installed, and the upper surface of the replaceable support block 10 abuts against the bottom of the material to be processed for support.

[0036] Since the diameters of the processed lining pipes are not necessarily the same, and since the lifting stroke of the cylinder is fixed, if the replaceable support blocks 10 are made according to the diameters of different lining pipes, then multiple models of replaceable support blocks 10 will be required. Therefore, different numbers of gaskets 15 with different thicknesses are used to adapt to lining pipes with different diameters, where the thickness of the gaskets is 1, 2, 5 and 10 mm. Gaskets with thicknesses of 1, 2, 5 and 10 mm can adapt to the size requirements of most lining pipes. In this way, only a few types of replaceable support blocks 10 can be made, such as replaceable support blocks with arc-shaped or V-shaped surface shapes as above.

[0038] A rack 16 parallel to the slide rail is provided at the bottom of the aisle, and a gear 17 driven by a motor 18 and capable of meshing with the rack is provided on the support seat. The motor starts working by connecting the power supply (controlling the opening and closing of the switch), realizing the rotation of the gear 17, and then driving the support seat to move along the track.

[0039] The working method of the laser blanking mechanism of the lining pipe fittings of the utility model is to determine the position to which the support seat and its upper components move along the slide rail according to the length of the lining pipe fittings after cutting when processing a batch of lining pipe fittings, and remove several support bars above the support seat position to avoid interference when the lifting platform and the replaceable support block are lifted or lowered, while the support bars at other positions are retained.

[0040] During operation, after the material to be processed (lining pipe fittings) passes through the loosened jaws and moves to the top of the support seat (the moving power can be provided by manual labor or by a conveyor belt, etc.), the lifting platform rises and supports the first end of the material to be processed, and at the same time, the jaws clamp the material to be processed at a position away from the first end, and the laser equipment (laser cutting equipment) starts to emit a laser to cut the lining pipe fittings, and the cut lining pipe fittings slide off the support block and slide from a high place to a low place along the surface of several support bars, and the lifting platform descends; thereafter, the jaws release the position of the material to be processed away from the first end, and the material to be processed (lining pipe fittings) moves to the top of the support seat, and the lifting platform rises and supports the first end of the material to be processed, and the subsequent processes are as described above.

[0041] The utility model provides a lining pipe laser blanking mechanism with support from the support seat and the support block thereon, so that the free end (first end) of the lining pipe can be supported, thus avoiding deviation during processing, which is beneficial to ensuring processing accuracy; by providing a plurality of parallel and spaced support bars, and the support bars are supported by side walls arranged at different heights on both sides, the processed debris can be discharged into the aisle from the interval between the two support bars, and each support bar forms an inclined slope, which is beneficial for the lining pipe to slide to a low position, so as to perform unified material collection and facilitate use.
