Description
Technical Field
[0001] This invention relates to the field of metal combination processing technology, and in particular to a mechanical sandblasting combination machine tool for metal wire mesh and its metal wire mesh structure. Background Technology
[0002] Metal wire mesh is a widely used basic industrial product. Its core functions are to achieve filtration and separation (such as petrochemical filtration, food screening, and air purification) using its mesh structure, reinforcement and composite (as a skeleton layer for rubber and plastics in tires or building templates), protection and safety (mechanical protective fences, explosion-proof mesh for doors and windows), and construction and decoration (wired glass, exterior wall decorative mesh). On this basis, its surface interface can be recreated by sandblasting and grinding, which significantly enhances the bonding force with coatings or composite materials and obtains a matte and beautiful texture. Laser cutting can give it a precise shape and customized openings to meet the high precision requirements of medical implants.
[0003] The existing metal wire mesh sandblasting and cutting processes are carried out separately, using different machine tools, resulting in cumbersome processes and mechanical structures, low production efficiency, and low automation. Secondly, the wire mesh, which has been wound for a long time, will have local bending or wrinkling during sandblasting and cutting, making it impossible to shape effectively and reducing the processing quality. Furthermore, when laser cutting the wire mesh, heat dissipation is poor, and molten metal slag will adhere to the mesh walls and openings, affecting subsequent use.
[0004] In summary, considering that existing facilities cannot meet the needs of work, we propose a mechanical sandblasting combination machine tool for metal wire mesh and its metal wire mesh structure. Summary of the Invention

A return spring sleeved on the outside of the plug rod is fixed between the sealing plug and the cavity wall of the water pressure chamber.
[0017] As a preferred embodiment of the mechanical sandblasting combination machine tool for metal wire mesh described in this invention, wherein: a number of spray cylinders are equidistantly installed on the right end face of the hydraulic pressure device, the number of spray cylinders is preferably 6-10, the inside of the spray cylinder is provided with a spraying inner cavity communicating with the hydraulic pressure chamber, the sealing plug is movably disposed in the spraying inner cavity, the end face of the spray cylinder is provided with a number of atomizing holes communicating with the spraying inner cavity, the number of atomizing holes is not less than 1, and the atomizing holes extend and are distributed on the groove wall of the lower opening groove.
[0018] As a preferred embodiment of the mechanical sandblasting combination machine tool for metal wire mesh described in this invention, the air tank is connected to an air supply branch pipe, the air supply branch pipe extends downward into the interior of the negative pressure adsorption platform, the end of the air supply branch pipe is equipped with a multi-hole connector, the multi-hole connector is connected to a bottom cleaning sandblasting head that acts on the inclined filter screen, and the number of the cleaning sandblasting heads is preferably 2-6 sets.
[0019] As a preferred embodiment of the mechanical sandblasting combination machine tool for metal wire mesh described in this invention, the following features: short shafts are welded to the upper positions of both ends of the support rollers; the short shafts are connected to the inner wall of the negative pressure adsorption table via a second bearing seat; one set of the short shafts extends outward and is sleeved with 1-2 sets of pulleys; adjacent pulleys are connected by belts for transmission; one set of the several sets of short shafts is connected to a second servo motor via a coupling; and each set of support rollers is eccentrically rotated to seal into the negative pressure adsorption port.
[0020] This invention provides an improved mechanical sandblasting machine tool for metal wire mesh and its metal wire mesh structure, which has the following significant improvements and advantages compared with the prior art: Two sets of lifting cylinders are activated, and the lifting rods extend synchronously, driving the two sets of extrusion molds to move towards each other. The extrusion grooves contact the corresponding annular extrusion airbags, compressing a local area of the airbags. The side away from the compression area then expands after the air accumulates. The annular extrusion airbags fully fit the end face of the mesh body with the expansion part. The upper and lower sets of annular extrusion airbags limit and fix the left position of the mesh body, achieving the purpose of flexible positioning. In conjunction with the straightening seat, the mesh body is pulled to the right in a straight line, so that the mesh body between the annular extrusion airbags and the straightening seat is fully straightened through the cooperation of the two, achieving the purpose of automatic correction and effectively solving the problem of local bending or wrinkling of the wire mesh.
[0021] The suction device inside the negative pressure suction seat is activated, generating negative pressure suction at several sets of negative pressure suction ports. This causes the mesh unit to be adsorbed onto several sets of arc-shaped support surfaces. On the one hand, the auxiliary cam clamping part limits and fixes the mesh, preventing it from being misaligned during sandblasting or cutting. On the other hand, waste and fine particles generated during sandblasting are promptly extracted after passing through the mesh holes and enter the interior of the negative pressure suction table, where they are intercepted by the inclined filter screen. This prevents the sand from damaging the back of the mesh and solves the problem of mesh clogging.
[0022] The movement of the moving stage and the laser cutting head are synchronized. When the moving stage passes a set of inclined sliders, the circular arc slider slides on the inclined sliders, and the two generate a squeezing force to pull the stopper rod outward. The stopper rod drives the sealing plug to instantly disengage from the spray cavity, allowing the water pressure in the water pressure chamber to enter the spray cavity and be sprayed outward from several sets of atomizing holes to form atomized liquid. The atomized liquid encounters the airflow that is being sprayed in the lower opening groove. Therefore, the airflow carries the atomized liquid towards the laser cutting position, achieving the purpose of timely heat dissipation and improving the quality of laser cutting.
[0023] The second servo motor is started, driving one set of short shafts to rotate. Through adjacent pulleys and belts, the transmission proceeds sequentially, causing several sets of support rollers to rotate eccentrically at a certain angle, blocking the corresponding negative pressure adsorption ports and creating a top-blocking effect. This prevents waste from overflowing during the blow-cleaning process. Then, air is supplied from the air tank, and the gas flows through the air supply branch pipe and is dispersed and sprayed from several sets of sand-cleaning nozzles. This effectively blows the inclined filter screen from the bottom, cleaning the residue on its outer surface and achieving automatic cleaning. This saves time and effort and effectively solves the problem of mesh clogging.
[0024] This invention combines three independent processes—sandblasting, cutting, and straightening—and utilizes a combination machine tool to simultaneously automate metal processing, significantly improving work efficiency and overcoming the problems of low production efficiency and high operating costs associated with independent machine tools.

One end of the lead screw 83 extends outward and is connected to a lead screw motor 86 via a coupling. Figures 15-18 .
[0045] Furthermore, a water pressure device 90 is fixed inside the heat sink 80 and to the left of the lower opening slot 89. One end of the water pressure device 90 is connected to a water supply pipe 91 and extends outward. A water pressure chamber 92 is laterally opened inside the water pressure device 90.

One end of the stopper rod 93 is fitted with a slanted slider 95, which has a lateral slant. A moving block 87 is fixed to the lower end of the moving platform 81, located to the left of the multi-functional nozzle 82. The lower end of the moving block 87 is fitted with an arc-shaped sliding head 88 that acts sequentially on the slanted slider 95. Figure 19 and Figure 20 As shown.
[0047] A sealing plug 96 is installed at the end of the stopper rod 93 away from the inclined slider 95. A return spring 97, sleeved on the outside of the stopper rod 93, is fixed between the sealing plug 96 and the cavity wall of the hydraulic chamber 92. Figure 19 and Figure 20 As shown.
[0048] Furthermore, several sets of spray cylinders 100 are equidistantly installed on the right end face of the water pressure device 90. Each spray cylinder 100 has an internal spray cavity 101 communicating with the water pressure chamber 92. A sealing plug 96 is movably disposed within the spray cavity 101, and the sealing plug 96 and the spray cavity 101 form a sliding seal. Several sets of atomizing holes 102 communicating with the spray cavity 101 are opened on the end face of the spray cylinder 100. The atomizing holes 102 extend and are distributed on the groove wall of the lower opening groove 89, such as... Figure 19 and Figure 20 As shown.
[0049] In this embodiment, in the initial state, the net body 1 of the roll 13 is first allowed to move to the right along the guide groove 11 and enter the support plate 61. At this time, the hydraulic cylinder 30 is activated, and the hydraulic telescopic rod 31 extends to drive the straightening seat 32 to move below the heat sink 80. The motion guide of the stationary clamping plate 33 is used to lift the end edge of the net body 1 and enter the upper end face of the stationary clamping plate 33. At this time, the first servo motor 46 is started, which drives the two sets of drive gears 44 on the horizontal shaft 45 to rotate synchronously at a certain angle, meshing with the moving cam roller 4. On the toothed part 43 of 0, the moving cam roller 40 is rotated at a certain angle, so that the cam clamping part 47 first contacts the end edge of the mesh body 1 during the downward movement (during the contact process, the cam clamping part 47 has an inward pulling force on the mesh body 1), and then it is clamped by the stationary clamping plate 33. Then the hydraulic telescopic rod 31 is retracted, and the straightening seat 32 pulls the mesh body 1 to the right in a straight line until the mesh body 1 completely enters the sandblasting area (the area of the mesh body 1 entering the sandblasting area is a single mesh body unit to be sandblasted and cut).
[0050] Then, two sets of lifting cylinders 22 are activated simultaneously, and the lifting rods 23 extend synchronously, driving the two sets of extrusion molds 24 to move towards each other. The extrusion grooves 25 contact the corresponding annular extrusion airbags 16, compressing a part of the airbag. The side away from the compression area gathers air and expands. The annular extrusion airbags 16 fully fit the end face of the net body 1 with the expansion part. The upper and lower sets of annular extrusion airbags 16 limit and fix the left position of the net body 1. At this time, the hydraulic telescopic rod 31 is retracted, and the straightening seat 32 pulls the net body 1 to continue to move straight to the right. The net body 1 between the annular extrusion airbags 16 and the straightening seat 32 is fully straightened through the cooperation of the two, achieving the purpose of automatic correction.
[0051] Then, the sand supply hopper 51 supplies sand particles to the sandblaster 50, while the air tank 54 supplies air to the inside of the sandblaster 50 through the air supply pipe 55. After the sand particles and air are mixed, they pass through the sandblasting pipe 53 at high speed to perform fixed-point sandblasting on the net body 1 in the sandblasting area of the guide mesh groove 11, forming a frosted surface on the upper end of the net body unit. At the same time as sandblasting, the suction device inside the negative pressure suction seat 70 is activated, generating negative pressure suction at several sets of negative pressure suction ports 65, causing the net body unit to be adsorbed onto several sets of arc-shaped support surfaces 64. On the one hand, the auxiliary cam clamping part 47 limits and fixes the net body 1, and on the other hand, the waste and fine particles generated during sandblasting are promptly extracted after passing through the mesh holes 3 and enter the inside of the negative pressure suction table 60, where they are intercepted by the inclined filter screen 66. When the adsorption work is completed, the waste and fine particles on the screen move downward and enter the waste sand hopper 68 through the collection port 67 for centralized collection.
[0052] After sandblasting, the laser cutter 76 is activated. The laser cutting head moves linearly along the cutting limit track 75. The laser cutter 76 generates a laser beam, which is highly focused through the internal optical system to form a tiny spot. The laser cutting head concentrates energy, and the mesh above absorbs the laser energy, causing the local temperature to rise rapidly. The high temperature causes the material to undergo a phase change, changing from a solid state to a liquid state or even a gas state, thus achieving the purpose of cutting. A transverse cut is made to form a cutting edge. At the same time as cutting, the sandblaster 50 supplies air to the sandblasting branch pipe 56 (at this time, the sand supply hopper 51 is closed, and the air tank 54 supplies air normally). The gas flows through the corrugated telescopic pipe 57 and is sprayed out from the multi-functional nozzle 82 towards the cutting edge.
[0053] Simultaneously, the lead screw motor 86 is started, and the lead screw 83 rotates, causing the moving stage 81 to move linearly along the direction of the lead screw 83 inside the heat sink 80 (the lead screw nut sleeve 84 and the lead screw 83 interact to generate motion power). The movement of the moving stage 81 and the laser cutting head are synchronized. When the moving stage 81 moves past a set of inclined sliders 95, the circular arc slide head 88 slides on the inclined sliders 95, and the two generate a squeezing force to pull the stopper rod 93 outward (the return spring 97 is compressed). The stopper rod 93 drives the dense The plug 96 instantly disengages from the spray cavity 101, allowing the water pressure in the water pressure chamber 92 to enter the spray cavity 101 and be sprayed outward from several sets of atomizing holes 102 to form atomized liquid. The atomized liquid encounters the airflow that is being sprayed in the lower opening groove 89, so the airflow carries the atomized liquid toward the laser cutting position to achieve timely heat dissipation. When the arc-shaped slider 88 passes the inclined slider 95, the sealing plug 96 returns to its original position and seals the spray cavity 101 in time under the compression force of the return spring 97.
[0054] After laser cutting, the sandblaster 50 supplies sand particles with normal airflow to the sandblasting branch pipe 56, and the multi-functional nozzle 82 sprays them towards the cutting edge. With the movement of the moving table 81, the molten slag at the cutting edge is treated to achieve the purpose of automatic cleaning. Then the treated mesh unit is taken out, and the above operation is repeated to circulate the mesh 1. Example 3
[0055] Based on Examples 1 and 2, the waste and fine particles intercepted on the inclined filter screen 66 have strong adsorption capacity, resulting in poor cleaning effect and easy clogging of the air-permeable mesh, interfering with the normal dust collection process. To solve the above technical problems, we connected an air supply branch pipe 110 to the outside of the air tank 54. A pulse valve is installed inside the air supply branch pipe 110, which extends downward into the interior of the negative pressure adsorption platform 60. Figures 21-22 As shown.
[0056] Specifically, a multi-hole connector 111 is installed at the end of the gas supply branch pipe 110. A sand-cleaning nozzle 112, which acts on the bottom of the inclined filter screen 66, is connected to the multi-hole connector 111. The arrangement of the sand-cleaning nozzles 112 can be designed according to actual conditions, such as... Figure 21 As shown.
[0057] Furthermore, short shafts 120 are welded to the upper positions of both ends of the support roller 63. The short shafts 120 are connected to the inner wall of the negative pressure adsorption platform 60 via a third bearing seat 121. One set of short shafts 120 extends outward and is fitted with 1-2 sets of pulleys 122. Adjacent pulleys 122 are connected by a belt 123 for transmission. One set of several sets of short shafts 120 is connected to a second servo motor 124 via a coupling. Each set of support rollers 63 is eccentrically rotated to seal into the negative pressure adsorption port 65 (large-area sealing is sufficient). Figure 22As shown.
[0058] In this embodiment, during cleaning, the second servo motor 124 is first started, driving one set of short shafts 120 to rotate. The shafts are connected to belts 123 via adjacent pulleys 122, and the transmission is sequential, causing several sets of support rollers 63 to rotate eccentrically at a certain angle, blocking the corresponding negative pressure adsorption port 65 and forming a top blocking effect. Then, the air tank 54 supplies air to the air supply branch pipe 110. The air flows through the air supply branch pipe 110 and is dispersed and sprayed out from several sets of sand-cleaning nozzles 112, effectively blowing the inclined filter screen 66 from the bottom to clean the residue on its outer surface.
