Description

Technical Field

[0001] The utility model relates to the technical field of metal plate processing, in particular to a production line for processing a mold wear-resistant plate substrate. Background Art

[0002] Mold wear-resistant plate is an important material used in molds to reduce mechanical wear. It is widely used in plastics, rubber, metal, glass and other fields. It is made of steel plate as the base material and cemented carbide powder sintered on its friction surface. During substrate processing, cutting, leveling, and surface pretreatment are performed in sequence according to demand. The existing processing process has the following problems: ① The strong light and smoke generated by the laser cutting machine during cutting will pollute the working environment. The solution adopted is mostly to install a dust cover on the cutting head. However, the shaking caused by the movement of the dust cover and the cutting head will affect the cutting accuracy of the cutting head; ② The positions of the upper and lower sets of pressure rollers of the leveling machine are fixed, and the transmission structure of the upper and lower sets of pressure rollers is complex. When leveling plates of different thicknesses, the spacing between the upper and lower pressure rollers needs to be adjusted. The entire adjustment process is very cumbersome, time-consuming and labor-intensive; ③ During the sandblasting and grinding process, the slag, abrasive and powder dropped on the workpiece are mixed together, affecting the efficiency of workpiece processing. At the same time, the drive parts of the existing turntable sandblasting machine are located below it and work together in the sandblasting box, which greatly affects its service life.

Therefore, it should not be understood as limiting the present invention. In addition, if the terms "first", "second", etc. appear in the description of the present invention, they are only used to distinguish the description and should not be understood as indicating or implying relative importance.

[0034] In the description of the embodiments of the present invention, it should be noted that, unless otherwise specified or limited, the terms "disposed" and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0035] As shown in the accompanying drawings, the present invention includes a laser cutting machine 100, a leveling machine 110 and a sandblasting machine 120 installed in sequence from front to back. The steel plate is cut into the required shape by the laser cutting machine 100, and then leveled by the leveling machine 110 in sequence. After leveling, it is placed in the sandblasting machine 120 at one time, and the front and back sides of the steel plate are processed respectively to obtain the required substrate, which is convenient for the staff to coat the friction surface of the substrate with cemented carbide powder and send it into the calcining furnace for sintering.

[0036] The structure and working mode of the laser cutting machine 100: It includes a workbench 1, a machine tool main body 2 and a light-shielding and dust-collecting device. A cutting water trough 4 is provided on the top of the workbench 1, and a group of receiving plates 5 are provided on the top of the cutting water trough 4. A cutting head 6 is provided on the vertical axis of the machine tool main body 2, and the cutting head 6 is controlled to perform cutting action above the workbench 1; the light-shielding and dust-collecting device includes an electric slide 10, a translucent cover 11 and a dust collector 12. The electric slide 10 is horizontally installed below the horizontal axis of the machine tool main body 2 and is linked to the slider of the horizontal axis of the machine tool main body 2. The translucent cover 11 can be adjustably installed on the slider of the electric slide 10. A cutting head avoidance hole is provided on the top of the translucent cover 11. The cutting head 6 is located in the translucent cover 11. The dust collector 12 is installed on one side of the workbench 1, and an exhaust port connected to the air inlet of the dust collector 12 is provided on one side of the translucent cover 11.

[0037] The machine tool main unit 2 is the mechanical part that realizes the X-, Y-, and Z-axis motion. The X-axis, or horizontal axis, controls the left and right movement of the cutting head 6. The Y-axis, or vertical axis, controls the forward and backward movement of the cutting head 6. The Z-axis controls the vertical movement of the cutting head 6. This is a conventional CNC laser cutting machine structure. During cutting, the X, Y, and Z axes work together to perform the cutting action.

[0038] The receiving plate 5 is used to support the plate. Water is filled in the cutting water tank 4, and the water level does not exceed the receiving plate 5, which is convenient for cooling and absorbing part of the smoke and dust after cutting.

[0039] The bottom of the translucent cover 11 in this case is open, which is used to cover the cut part of the plate. There is a gap between the bottom of the translucent cover 11 and the plate, and the gap is 3-5mm to prevent the translucent cover 11 from scratching the plate during movement. At the same time, it serves as an air inlet when vacuuming to prevent smoke and dust from escaping.

[0040] The cutting head 6 extends into the translucent cover 11 to perform the cutting. During use, the cutting head 6 does not come into contact with the translucent cover 11. In this embodiment, the translucent cover is made of a dark filter material to block strong light and reduce light pollution. The translucent cover 11 is controlled by an independent electric slide 10 and moves left and right with the cutting head 6. This movement does not interfere with the cutting head 6, ensuring cutting accuracy.

[0041] Preferably, the top of the receiving plate 5 is a serrated structure, and a group of receiving plate mounting grooves are respectively provided on the lateral sides of the cutting water trough 4, and the receiving plate 5 is movably inserted in the corresponding receiving plate mounting grooves; a group of longitudinal support plates 15 are provided in the cutting water trough 4, and a group of longitudinal support plate plug-in grooves are provided at the bottom of the receiving plate 5, and the middle part of the receiving plate 5 is movably inserted on a group of longitudinal support plates 15.

[0042] The serrated structure can reduce the contact area between the receiving plate 5 and the bottom of the plate, making cutting smoother and reducing the possibility of the plate and the receiving plate 5 sticking together due to the melt.

[0043] The receiving plate 5 is movably inserted into the corresponding receiving plate installation groove for easy replacement. When cutting, the receiving plate 5 below will inevitably be cut. When the toothed portion of the receiving plate 5 is severely damaged, it needs to be replaced to ensure the stability of the receiving plate 5 support.

[0044] The longitudinal support plate 15 is fixedly installed in the cutting water trough 4, located below the receiving plate 5, and is used to support the middle position of the receiving plate 5. At the same time, a group of longitudinal support plate plug-in grooves are provided at the bottom of the receiving plate 5. The middle part of the receiving plate 5 is movably plugged into a group of longitudinal support plates 15, which can effectively prevent the receiving plate 5 from deformation.

[0045] Furthermore, a portion of the receiving plate 5 and the longitudinal support plate 15 are both located below the water level of the cutting water tank 4 .

[0046] That is, the receiving plate 5 and the longitudinal support plate 15 are combined with the water surface to divide the cutting trough 4 into multiple relatively independent dust suction areas. The distance between the water surface and the plate is between 40-50 mm, which can quickly absorb heat and smoke. The smoke generated at the bottom of the plate during cutting will be concentrated in the corresponding dust suction area below and adsorbed by the water surface instead of quickly dissipating into the entire cutting trough 4.

[0047] Furthermore, a plug-in block 17 is provided on the slider of the electric slide 10 , a plug-in slot matching the plug-in block 17 is provided on the translucent cover 11 , and a height adjustment screw 18 is provided on the top of the plug-in slot of the translucent cover 11 .

[0048] The translucent cover 11 can be detachably mounted on the slider of the electric slide 10 by cooperating with the plug-in slot and the plug-in block 17 . The height of the translucent cover 11 can be adjusted by the height-adjusting screw 18 according to the thickness of the plate.

[0049] Preferably, the translucent cover 11 is a rectangular cover parallel to the horizontal axis of the machine tool main body 2, and the cutting head avoidance hole is a long hole, which facilitates the cutting head 6 to move left and right in the translucent cover 11 for cutting.

[0050] Furthermore, two photoelectric switches 20 are provided on the slider of the electric slide 10 for controlling the left and right movement of the electric slide 10 respectively, and a sensing block 21 that cooperates with the photoelectric switches 20 is provided on the slider of the horizontal axis of the machine tool host 2.

[0051] In the initial state of this case, the cutting head 6 is located in the middle of the translucent cover 11. When the left and right movement of the cutting head 6 during the cutting process does not exceed the range of the translucent cover 11, that is, it does not exceed the two end positions of the cutting head avoidance hole, the translucent cover 11 remains stationary, and the cutting head 6 moves left and right in the fixed translucent cover 11 for cutting; on the contrary, when the cutting head 6 needs to move left and right to a position outside the translucent cover 11 for cutting, the translucent cover 11 will move laterally, so that the cutting head 6 is always located in the translucent cover 11.

[0052] The specific operation is that two photoelectric switches 20 are provided on the slider of the electric slide 10. The one on the left controls the electric slide 10 to move to the left, and the one on the right controls the electric slide 10 to move to the right. For example, the horizontal axis of the machine tool mainframe 2 moves the cutting head 6 to the left. When the sensing block 21 on the horizontal axis approaches the photoelectric switch 20 on the left, it means that the cutting head 6 has moved to the position closest to the left side of the translucent cover 11. At this time, the electric slide 10 starts to move the translucent cover 11 to the left by half a cover to ensure that the cutting head 6 has enough space to move left and right in the translucent cover 11. Conversely, when the sensing block 21 on the horizontal axis approaches the photoelectric switch 20 on the right, it means that the cutting head 6 has moved to the position closest to the right side of the translucent cover 11. At this time, the electric slide 10 starts to move the translucent cover 11 to the right by half a cover.

[0053] The structure and working method of the leveling machine 110 include a frame 25, a lower roller press base 26, and an upper roller press base 27. The lower roller press base 26 is fixed to the frame 25. The upper roller press base 27 is movably mounted on the frame 25 via a lifting screw 28 and is located directly above the lower roller press base 26. The lower roller press base 26 is equipped with a set of lower leveling rollers 30. The upper roller press base 27 is equipped with a set of upper leveling rollers 31 that are staggered in front and behind the lower leveling rollers 30.

[0054] The lower roller press base 26 is provided with a height limiting mechanism 35 for limiting the distance between the lower leveling roller 30 and the upper leveling roller 31, and a driving mechanism 36 for driving the lower leveling roller 30 and the upper leveling roller 31 to rotate. The front end of the lower roller press base 26 is provided with a loading roller 37, and the rear end of the lower roller press base 26 is provided with a discharging platform 38.

[0055] The lower roller press base 26 and the upper roller press base 27 are distributed up and down, and are both relatively independent entities, which facilitates the adjustment of the overall distance between the lower leveling roller 30 and the upper leveling roller 31.

[0056] The lifting screw 28 is used to control the up and down movement of the upper roller press base 27, and the height limiting mechanism 35 is used to limit the distance between the lower roller press base 26 and the upper roller press base 27. Before adjustment, the upper roller press base 27 is lifted up by the lifting screw 28, and then the height limiting mechanism 35 is adjusted. After the adjustment is completed, the upper roller press base 27 is lowered and pressed tightly. At this time, the distance between the lower roller press base 26 and the upper roller press base 27 can be fixed.

[0057] Furthermore, the four corners of the upper roller press base 27 are each provided with a guide rod 40 , and the four corners of the lower roller press base 26 are each provided with a guide sleeve 41 that matches the guide rod 40 .

[0058] Through the cooperation of the guide rod 40 and the guide sleeve 41, the upper roller press base 27 can maintain vertical lifting and stability on the horizontal plane when moving up and down, and the lower leveling roller 30 and the upper leveling roller 31 always remain parallel.

[0059] Preferably, the height limiting mechanism 35 is composed of two pairs of worm gear elevators 42 , each pair of worm gear elevators 42 is synchronously lifted and lowered by a transmission rod, and the two pairs of worm gear elevators 42 are symmetrically installed on the left and right sides of the lower roller press base 26 .

[0060] Worm gear elevator mounting grooves are provided on the left and right sides of the lower roller press base 26. Each pair of worm gear elevators 42 are synchronously lifted and lowered by a transmission rod. A crank that drives the transmission rod to rotate is provided on the lower roller press base 26. The transmission rod and the crank are driven by gears. By turning the crank, the transmission rod is driven to rotate to achieve synchronous lifting of a pair of worm gear elevators.

[0061] Furthermore, fixing lugs 43 are symmetrically provided at the four corners of the lower roller press base 26 and the upper roller press base 27, and the upper and lower fixing lugs 43 are fixed by bolts.

[0062] After the spacing between the lower roller press base 26 and the upper roller press base 27 is adjusted, the four corners are fixed with bolts to further improve the stability of the lower leveling roller 30 and the upper leveling roller 31 during the rolling process.

[0063] Preferably, the driving mechanism 36 includes a leveling motor 45, a fixed transmission gear 46 and a movable transmission gear 47, and a group of lower leveling rollers 30 and a group of upper leveling rollers 31 are all driven by chains; the fixed transmission gear 46 is installed on one side of the upper roller press base 27, and is gear-transmitted to the upper leveling roller 31, and the movable transmission gear 47 is movably installed on one side of the lower roller press base 26 through a swing arm 50, and is gear-transmitted to the lower leveling roller 30, and a swing arm drive assembly 51 is provided on the lower roller press base 26, and the swing arm drive assembly 51 controls the movement of the movable transmission gear 47 to engage with the fixed transmission gear 46 for transmission, and the leveling motor 45 is installed on one side of the lower roller press base 26, and drives the lower leveling roller 30 to rotate.

[0064] Both ends of the lower leveling roller 30 and both ends of the upper leveling roller 31 are provided with sprockets, and the lower leveling rollers 30 and the upper leveling rollers 31 are connected by chains.

[0065] In this case, gears are provided at the ends of one of the lower leveling rollers 30 and one of the upper leveling rollers 31. A fixed transmission gear 46 is mounted on the upper roller press base 27 and can move up and down with the upper roller press base 27, constantly meshing with the gear on the upper leveling roller 31. One end of a swing arm 50 is coaxially mounted on the geared end of one of the lower leveling rollers 30, meaning that the movable transmission gear 47 constantly meshes with the gear on the lower leveling roller 30. When adjusting the spacing, the swing arm drive assembly 51 controls the height adjustment of the movable transmission gear 47 to facilitate meshing with the fixed transmission gear 46. The swing arm drive assembly 51 in this case is a worm gear lifting assembly, with the lifting rod hinged to the bottom of the swing arm 50 and the base hinged to the lower roller press base 26.

[0066] Furthermore, a pair of transverse limit rollers 53 are provided at the discharge end of the loading roller 37, a transverse chute is provided on the loading roller 37, a pair of sliders are provided in the transverse chute, and a locking screw is screwed on the slider, and the pair of transverse limit rollers 53 are respectively installed on the corresponding sliders.

[0067] The distance between the two transverse limit rollers 53 can be adjusted according to the width of the plate. When in use, the steel plate is fed in from between the two transverse limit rollers 53. After the front end of the steel plate enters the lower leveling roller 30 and the upper leveling roller 31, the two transverse limit rollers 53 can effectively prevent the steel plate from sliding sideways and can keep moving in a straight line.

[0068] The structure and working method of the sandblasting machine 120 include a sandblasting box 60, a screening hopper 61, and a rotary sandblasting table 62. The sandblasting box 60 is installed on top of the screening hopper 61 and is connected to the screening hopper 61 to form a sandblasting cavity. A sandblasting gun 63 is provided in the sandblasting box 60, and an inclined screen plate 65 is provided in the screening hopper 61. A sand outlet connected to the sandblasting gun 63 is provided on one side of the screening hopper 61 at the lower end of the screen plate 65. A slag collecting box 66 is provided at the bottom of the screening hopper 61.

[0069] The rotary sandblasting platform 62 is movably mounted on the top of the screening hopper 61 . A driving motor 68 for driving the rotary sandblasting platform 62 to rotate is provided on one side of the screening hopper 61 .

[0070] The sandblasting box 60 is provided with a transparent observation window and a pair of hand holes. Rubber gloves are provided in the hand holes to facilitate the staff to put their hands into the sandblasting box 60 to operate the sandblasting gun 63. A pressure tank and a medium power system are provided on one side of the sandblasting box 60 to pressurize the abrasive and spray it out through the sandblasting gun 63. The working principle is the same as that of the existing press-in dry sandblasting machine.

[0071] In this case, a sieve plate 65 is provided in the screening hopper 61. After the abrasive grinds the workpiece and falls, it is screened through the sieve plate 65 together with the working slag. The complete abrasive is located above the sieve plate 65, while the smaller slag and powder pass through the sieve plate 65 and fall into the slag collecting box 66 below, completing the sorting and ensuring the grinding effect of the abrasive.

[0072] Secondly, the driving motor 68 of this case is located outside and separated from the rotating sandblasting table 62. When driving the rotating sandblasting table 62 to rotate, it will not be affected by the abrasive in the sandblasting chamber, thereby extending its service life.

[0073] When taking or placing workpieces, the rotary sandblasting table 62 can be moved out of the sandblasting box 60 , which is convenient and quick.

[0074] Furthermore, a pick-up door is provided on one side of the sandblasting box 60 , and a group of cleaning nozzles 70 facing the rotating sandblasting table 62 are provided on the rear side of the sandblasting box 60 at the end of the pick-up door.

[0075] The access door seals the sandblasting chamber 60 and allows for workpiece access. A cleaning nozzle 70, connected to a pressure tank, uses high-pressure gas within the tank to purge abrasive from the rotating sandblasting table 62 and the workpiece surface, preventing it from being carried out and contaminating the environment. During installation, the cleaning nozzle 70 is tilted downward, toward the central axis of the rotating sandblasting table 62. Before the rotating sandblasting table 62 is removed, the cleaning nozzle 70 is activated, and the rotating sandblasting table 62 remains in rotation.
