Description

Technical Field

[0001] The invention belongs to the technical field of plasma cutting devices and relates to a fully automatic plasma cutting device for die-casting parts. Background Art

[0002] Plasma cutting machine is a machine that processes metal materials with the help of plasma cutting technology. Plasma cutting is a processing method that uses the heat of high-temperature plasma arc to partially or partially melt (and evaporate) the metal at the cut of the workpiece, and uses the momentum of high-speed plasma to remove the molten metal to form a cut. Plasma cutting machines are widely used in various industries such as automobiles, locomotives, pressure vessels, chemical machinery, nuclear industry, general machinery, engineering machinery, steel structures, etc.

[0003] Die casting is a kind of pressure casting part. It uses a pressure casting mechanical die casting machine with a casting mold installed. The heated liquid copper, zinc, aluminum or aluminum alloy metal is poured into the feed port of the die casting machine. The die casting machine casts copper, zinc, aluminum or aluminum alloy parts of the shape and size limited by the mold. Such parts are usually called die castings. After the die casting is die-cast, the excess part of the edge is generally cut off by a cutting machine and then polished, and most of them are cut by a fully automatic plasma cutting machine. When cutting the die casting, a large amount of powder debris and waste will be generated. The debris and waste generally fall directly on the workbench, and there are no corresponding protective measures, resulting in debris splashing, which is easy to cause harm to the staff. At the same time, the scattered debris and waste are not easy to collect in a centralized manner, which brings great trouble to the subsequent cleaning work. Therefore, we propose a fully automatic plasma cutting device for die casting parts to solve the above-mentioned problems. Summary of the invention

[0044] Example 1

[0045] like Figure 1 - Figure 4 As shown, a fully automatic plasma cutting device for die-cast parts includes a cutting chamber 1, a smoke exhaust pipe 3, a feed port 10 and a chamber door 14, and also includes a plasma cutting machine 4 arranged on one side of the top wall of the cutting chamber 1. The die-cast parts are cut inside the cutting chamber 1. The feed port 10 is opened on one side of the cutting chamber 1 for the entry and exit of the die-cast parts. Two mounting blocks 15 are symmetrically fixedly connected to the inner wall of the cutting chamber 1 on one side close to the feed port 10. The same first rotating rod 16 is rotatably connected between the two mounting blocks 15. The outer wall of the first rotating rod 16 is fixedly sleeved with a sealing baffle 17 for sealing the feed port 10. The first rotating rod 16 is sleeved with two first torsion springs 18 located on both sides of the sealing baffle 17, and the two ends of the first torsion spring 18 are respectively fixedly connected to one side of the corresponding mounting block 15 and one side of the sealing baffle 17. When no die-cast parts are fed into the cutting chamber 1, the sealing baffle 17 is in a vertical state under the elastic force of the first torsion spring 18, and the feed port 10 is blocked, so that the air in the cutting chamber 1 cannot be discharged from the feed port 10 and can only be discharged from the smoke exhaust pipe 3; when the feeding mechanism feeds the die-cast parts inward from the feed port 10, it can resist the sealing baffle 17 and automatically push it to flip, and the first torsion spring 18 is in a torsion storage state to realize feeding; and after the feeding mechanism takes out the cut die-cast parts, it can be taken out by the elastic force of the first torsion spring 18. The dynamic sealing baffle 17 automatically flips and resets to automatically seal the feed port 10 again. The smoke exhaust pipe 3 is fixedly connected to the top side of the cutting chamber 1, and the other end is connected to the smoke recovery and treatment device or directly discharged to the outside. The smoke generated during the cutting process is discharged outward from the smoke exhaust pipe 3, and the exhaust of the smoke will be accelerated during the blowing process of the blowing mechanism. At the same time, it also plays the role of air replacement in the cutting chamber 1 to avoid excessive smoke retention. The chamber door 14 is arranged on the side of the cutting chamber 1 away from the feed port 10. Opening the chamber door 14 facilitates the cleaning of powder debris inside the cutting chamber 1.

[0046] Example 2

[0047] This embodiment is a further improvement of the previous embodiment: Figure 1 - Fig.11As shown, a fully automatic plasma cutting device for die-cast parts is used in the field of plasma cutting, and also includes a feeding mechanism used in conjunction with a feed port 10. The die-cast parts are fixed on the feeding mechanism and fed into a cutting chamber 1 from the feed port 10, and then cut by a plasma cutting machine 4. The blocking mechanism is automatically opened during the feeding of the die-cast parts, and is automatically closed after the material is discharged; the feeding mechanism includes a moving column 2 used in conjunction with the feed port 10, a placing frame 13 is provided at one end of the moving column 2, a placing hole 20 is opened at the top of the placing frame 13, a plurality of placing bars 22 for placing the die-cast parts are fixedly connected side by side and equidistantly inside the placing hole 20, and a clamping assembly for clamping and fixing the die-cast parts is provided in the placing hole 20. First, the die-cast part is placed on the placement bar 22 in the placement hole 20, and then the die-cast part is fixed and clamped by the clamping assembly, and then it is sent into the cutting chamber 1 through the feed port 10, and the die-cast part is located directly under the plasma cutting machine 4, and then the die-cast part is plasma cut, and the fragments and debris generated by the cutting can fall from the gap between the placement bars 22 to the bottom of the cutting chamber 1 for stacking and storage.

[0048] In one aspect of the present embodiment, the clamping assembly includes a groove 24 provided on the inner wall of one side of the placement hole 20, a bidirectional screw 25 is connected in a lateral rotation in the groove 24, and one end of the bidirectional screw 25 is rotated to extend to the outside of the placement frame 13 away from the moving column 2, and two nut blocks 26 are symmetrically threaded on the positive and negative thread segments of the bidirectional screw 25, and the two nut blocks 26 are both slidably connected in the groove 24, and one side of the two nut blocks 26 is fixedly connected with a clamping block 27 for clamping the die-casting part. After the die-casting part is placed in the placement hole 20, the bidirectional screw 25 is rotated to drive the two nut blocks 26 to move closer to each other, and at the same time drive the two clamping blocks 27 to move closer to each other, so as to clamp and fix the die-casting part, which is convenient for stable cutting.

[0049] In one aspect of the present embodiment, two horizontal plates 11 located below the placement rack 13 are symmetrically fixedly connected to one side of the moving column 2, two guide rods 12 are symmetrically fixedly connected to the tops of the two horizontal plates 11, and the placement rack 13 is slidably sleeved on the four guide rods 12, one side of the placement rack 13 is slidably connected to one side of the moving column 2, the outer walls of the four guide rods 12 are sleeved with first springs 19, the two ends of the first springs 19 are respectively fixedly connected to the bottom of the placement rack 13 and the top of the horizontal plate 11, and the top side of the two horizontal plates 11 is fixedly connected to the same support bar 23, and the bottom of the placement rack 13 is in contact with the top of the support bar 23. The four guide rods 12 can play a stabilizing effect of sliding guide for the placement rack 13, and the setting of the support bar 23 can play a role in limiting the downward movement of the placement rack 13, and at the same time can play a stabilizing support effect for the placement rack 13, so as to prevent the die-cast parts and the placement rack 13 from moving downward when the die-cast parts are cut.

[0050] Example 3

[0051] This embodiment is a further improvement of the previous embodiment: Figure 1 - Figure 8As shown, a fully automatic plasma cutting device for die-cast parts also includes an air blowing mechanism arranged in the cutting chamber 1, which is used in conjunction with the feeding mechanism, so that the feeding mechanism automatically inhales air during the feeding process, and then the feeding mechanism blows air during the discharging process to blow off the powder debris attached to the die-cast parts, thereby achieving an automatic cleaning effect and avoiding the powder debris from being taken out; the air blowing mechanism includes a piston box 5 fixedly connected to the inside of the cutting chamber 1 and located above the feed port 10, the piston box 5 is internally sealed and slidably connected to a piston plate 6, one side of the piston plate 6 is symmetrically fixedly connected with two piston rods 8, and one end of the two piston rods 8 extends outward and is respectively located on both sides of the plasma cutting machine 4, and the two piston rods 8 are fixedly connected at one end away from the piston plate 6. A movable plate 9 is fixedly connected to the two horizontal plates 11, and a one-way air inlet pipe 7 is fixedly connected to one side of the top of the piston box 5. One end of the one-way air inlet pipe 7 extends to the outside of the cutting chamber 1. Two one-way air outlet hoses 31 are symmetrically fixedly connected to the bottom of the piston box 5. One side of the two movable plates 9 is fixedly connected to the same U-shaped plate 29 located above the placement rack 13, and the cutting head of the plasma cutting machine 4 is located on the inner side of the U-shaped plate 29. An air supply pipe 30 is fixedly connected to the U-shaped plate 29 in a horizontal manner, and both ends of the air supply pipe 30 are respectively fixedly connected to one end of the two one-way air outlet hoses 31. The outer wall of the air supply pipe 30 is inclined and provided with a plurality of air outlet heads 32, and the air outlet angle of the air outlet head 32 is aligned with the placement hole 20. When the moving column 2 brings the placement rack 13 into the cutting chamber 1 from the feed port 10, the two horizontal plates 11 first push the sealing baffle 17 to flip, and then one end of the two horizontal plates 11 respectively contacts one side of the two movable plates 9. As the moving column 2 continues to move, the horizontal plate 11 can push the movable plate 9 to move, and at the same time drive the piston rod 8 to move, and then drive the piston plate 6 to move. At this time, the air outside the cutting chamber 1 can be sucked into the piston box 5 from the one-way air inlet pipe 7 for storage, and the movable plate 9 also drives the U The mold plate 29 moves, and drives the air outlet head 32 to move synchronously with the placement rack 13 through the air supply pipe 30, so that the air outlet head 32 is always aligned with the placement hole 20; through the setting of the one-way air outlet hose 31, the U-shaped plate 29 can be easily moved back and forth with the movable plate 9; when one side of the movable plate 9 conflicts with the inner wall of one side of the cutting chamber 1, the movable column 2 cannot continue to move, and the placement rack 13 drives the die-cast parts to be located just below the plasma cutting machine 4, and then the plasma cutting of the die-cast parts is achieved through adjustment operations.

[0052] Example 4

[0053] This embodiment is a further improvement of the previous embodiment: Figure 1 - Fig.10As shown, the bottom of the two movable plates 9 close to the corresponding horizontal plate 11 are fixedly connected with a fixed block 40, the top of the fixed block 40 is slidably penetrated by a sliding rod 41, the top of the sliding rod 41 extends upward and is fixedly connected with a movable block 42, the bottom end of the sliding rod 41 extends downward and is fixedly sleeved with a rectangular block 43, the outer wall of the sliding rod 41 is sleeved with a second spring 44, and the two ends of the second spring 44 are respectively fixedly connected to the bottom of the fixed block 40 and the top of the rectangular block 43, the bottom of the two horizontal plates 11 is away from the movable column 2. The side edge is fixedly connected with a clamping block 21 that is engaged with the corresponding movable block 42, and the movable block 42 is provided with an inclined surface that cooperates with the clamping block 21 on the side away from the movable plate 9. When the cross plate 11 enters the cutting chamber 1 from the feed port 10 along with the moving column 2, the cross plate 11 drives the clamping block 21 to move, and makes the clamping block 21 first conflict with the inclined surface of the movable block 42. In the process of continuing to move, the movable block 42 will be squeezed to move downward, and at the same time, the slide bar 41 will be driven to move downward and stretch the second spring 44. When one side of the cross plate 11 contacts one side of the movable plate 9, the clamping block 21 is just misaligned with the movable block 42, and the movable block 42 is reset upward along with the slide bar 41 under the elastic force of the second spring 44, and the clamping block 21 is stuck between the movable plate 9 and the movable block 42; the cross plate 11 pushes the movable plate 9 to move, and drives the piston plate 6 to move, and the air outside the cutting chamber 1 is sucked into the piston box 5 through the one-way air inlet pipe 7; when the cutting of the die-cast parts is completed, the movable column 2 is pulled outward, and the placement rack 13 is driven to move outward to take the cut die-cast parts. The movable plate 9 is pulled back to its original position in the direction of the feed port 10 by the contact between the clamping block 21 and the movable block 42. At the same time, the piston plate 6 is pushed back to its original position by the piston rod 8. At this time, the air sucked into the piston box 5 can be pushed out into the air pipe 30 through the one-way air outlet hose 31, and then sprayed out from the air outlet head 32. Since the air pipe 30 and the air outlet head 32 move synchronously with the movable plate 9 through the U-shaped plate 29, and the air outlet head 32 is always aligned with the placement hole 20, the die-cast parts can be continuously blown and cleaned during the process of being taken out by the air outlet head 32, and the powder and debris remaining on the surface of the die-cast parts during cutting can be blown off and left in the cutting chamber 1, so as to avoid bringing some powder and debris out of the cutting chamber 1, and also reduce the trouble of cleaning after the staff takes it out.When the air outside the cutting chamber 1 is blown into the cutting chamber 1 from the air outlet head 32, on the one hand, the powder debris remaining when the surface of the die-cast parts is cut can be cleaned up, and on the other hand, the air inside the cutting chamber 1 can be replaced. When the die-cast parts are plasma cut, a large amount of smoke will be generated. Since the air inside the cutting chamber 1 is not circulated, the smoke dissipates very slowly in the cutting chamber 1. If the smoke is not sucked out by the suction device, a large amount of it will remain in the cutting chamber 1. If the suction device is used to smoke, since the suction intensity of the suction device is generally very large, the metal dust fragments in the smoke will inevitably be sucked away, which is not convenient for subsequent smoke treatment. If it is discharged directly, it will also have a certain impact on the air environment. At this time, by replacing the air, the outside air can be used, and the pressure difference between the inside and the outside can be used to discharge the smoke inside the cutting chamber 1 to the outside, which accelerates the dissipation of the smoke and reduces the emission of metal dust. At the same time, no additional suction device is required to work, thereby reducing energy consumption.

[0055] This embodiment is a further improvement of the previous embodiment: Figure 1 - Fig.13 As shown, the two rectangular blocks 43 are fixedly connected to the side away from the corresponding movable plate 9 with a stopper 45, and the bottom inner wall of the cutting chamber 1 is arranged in a rectangular shape and fixedly connected with four vertical rods 33, and the tops of the four vertical rods 33 are fixedly connected with the same fixed seat 34, and the fixed seat 34 is symmetrically fixedly connected to the side away from each other with two L-shaped stoppers 39 used in conjunction with the corresponding stopper 45, and one side of the stopper 45 is provided with an inclined surface used in conjunction with the L-shaped stopper 39. When the movable plate 9 is in the initial state, as shown in FIG. Fig.15 As shown, at this time, the L-shaped support rod 39 is in a state of resistance to the support block 45, and at the same time, the slide rod 41 is moved downward and the second spring 44 is in a stretched state, and the bottom of the movable block 42 is in contact with the top of the fixed block 40; when the horizontal plate 11 enters the cutting chamber 1 along with the movable column 2 and contacts the movable plate 9, the block 21 can just pass over the top of the movable block 42, and then as the horizontal plate 11 pushes the movable plate 9, the support block 45 begins to move away from the L-shaped support rod 39 and gradually leaves the state of resistance. At this time, the movable block 42 will move upward under the elastic force of the second spring 44 After the movable plate 9 is reset, the card block 21 is clamped between the movable plate 9 and the movable block 42, so that the movable plate 9 can be automatically brought back when the horizontal plate 11 is pulled outward, thereby achieving the effect of blowing; and in the overall return process, after the block 45 contacts the L-shaped contact rod 39, the movable block 42 will be automatically driven downward through the sliding rod 41 to release the clamping of the card block 21, so that when the movable plate 9 is returned to the initial state, the conflict between the card block 21 and the movable block 42 is automatically released, so that the horizontal plate 11 and the placement rack 13 can be moved outward normally along with the movable column 2.

[0056] Example 6

[0057] This embodiment is a further improvement of the previous embodiment: Figure 1 - Fig.14 As shown, the top of the fixed seat 34 is provided with a plurality of through holes 35 arranged side by side and at equal intervals, and a second rotating rod 36 is connected to the inner side of the through hole 35 in a transversely rotatable manner, and a rotating block 37 is fixedly sleeved on the outer wall of the second rotating rod 36, and two second torsion springs 38 are sleeved on the outer wall of the second rotating rod 36, respectively located on both sides of the rotating block 37, and the two ends of the second torsion spring 38 are respectively fixedly connected to the inner wall of the through hole 35 and one side of the rotating block 37, and a top block 28 used in conjunction with the rotating block 37 is fixedly connected to one side of the bottom of the placement frame 13, and a slope used in conjunction with the rotating block 37 is provided on the side of the top block 28 close to the moving column 2. First, as shown in FIG. Fig.15 As shown, when the moving column 2 does not move the placement rack 13 into the cutting chamber 1 or the cross plate 11 does not push the movable plate 9 to move, the rotating block 37 is in a vertical state with its top extending upward. When the moving column 2 drives the placement rack 13 into the cutting chamber 1 and pushes the movable plate 9 to move, the top block 28 first contacts the rotating block 37 and can push the rotating block 37 to rotate as it moves, which will not affect the normal feeding of the die-cast parts. When the top block 28 is free from the contact with the rotating block 37, it will automatically reset the rotating block 37 under the elastic force of the second torsion spring 38. After the moving column 2 has completely fed the die-cast parts into place, as shown in FIG. Fig.14 As shown, the top block 28 completely passes over all the rotating blocks 37, while some of the rotating blocks 37 are pressed by the moving column 2 and cannot be reset, but it does not affect the use of the entire device and the cutting operation; when the die-casting parts are cut, the moving column 2 pulls the placement rack 13 to move outward for discharging, at this time, the top block 28 and the rotating block 37 move in the opposite direction to contact, because the rotating block 37 is resisted by the inner wall of the through hole 35 and cannot rotate clockwise, thereby playing the role of rotation limit, at this time, through the inclined surface on the top block 28 and the resistance of the rotating block 37, the top block 28 can be driven to move upward, thereby driving the placement rack 13 to slide upward and stretch the first spring 19, when the top block 28 is separated from the resistance with the rotating block 37, the placement rack 13 is driven to reset downward under the elastic force of the first spring 19, thereby achieving the effect of vibrating the placement rack 13, thereby achieving the effect of vibrating the die-casting parts clamped inside, and can shake off the powder debris remaining on the die-casting parts during cutting, and cooperate with blowing to further improve the cleaning effect. By providing a plurality of rotating blocks 37 , a vibration can be achieved each time a rotating block 37 passes through, thereby greatly improving the cleaning effect of powder debris on the die-casting parts.

Those skilled in the art may make any selections according to their needs or convenience.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution, which should be included in the scope of the claims of the present invention.
