Description

Technical Field

[0001] The present invention belongs to the field of wire cutting technology, and in particular relates to a wire cutting device. Background Art

[0002] Wire cutting (WEDM) generally refers to electric spark wire cutting, which belongs to the category of electrical machining. The principle of wire cutting is that free positive ions and electrons accumulate in the field and quickly form an ionized conductive channel. At this stage, a current is formed between the two plates, resulting in countless collisions between particles, forming a plasma zone, and quickly rising to a high temperature of 8000 to 12000 degrees, instantly melting some materials on the surface of the two conductors. At the same time, due to the vaporization of the electrode and the dielectric fluid, a bubble is formed, and its pressure rises regularly until it is very high, and then the current is interrupted, the temperature suddenly drops, causing the bubble to explode inward, and the power generated throws the melted material out of the crater, and then the corroded material re-condenses into small spheres in the dielectric fluid and is discharged by the dielectric fluid. Then, through the monitoring and control of NC control and the execution of the servo mechanism, this discharge phenomenon is made uniform and consistent.

[0003] The existing device generally uses manual placement of workpieces during the processing process. During the placement process, there is a situation where the baffle may pinch the hand, which poses a certain safety hazard. Before processing, the thickness of the workpiece needs to be manually measured and the temperature of the wire cutting is adjusted. There is a certain error, the efficiency is not high, and the clamping force of the workpiece cannot be accurately adjusted, which will cause wear on the surface of the workpiece and affect the processing efficiency.

[0014] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: the present invention, through the coordinated use of the gripping manipulator and the equipment program, eliminates the need for workers to manually place the workpiece, preventing the workers' hands from being clamped by the two sets of baffles during the placement process; during the process of taking the workpiece, the thickness of the workpiece can be detected and the processing temperature of the wire cutting machine can be adjusted to prevent the surface of the workpiece from being burned or deformed due to excessive temperature, thereby ensuring that the mechanical strength and heat resistance of the workpiece are not affected;

The ink nozzle 44 is fixedly installed at one end of the gripping manipulator 4, and is used to spray the temperature-variable ink on the workpiece, so that the staff can observe the temperature of the workpiece after processing, and prevent burns caused by accidental touch during the gripping process. The gripping manipulator 4 is equipped with an ink supply pipeline externally connected to the ink supply device in the workshop, and is used to provide the temperature-variable ink for spraying;

[0033] A clamping assembly 5 is fixedly installed on one side of the operating table 14, and the clamping assembly 5 includes a first fixing seat 51, a telescopic gas rod 52, a clamping plate 53, and a clamping pad 531;

[0034] The first fixed seat 51 is fixedly installed on one side of the operating table 14, and is used to place two groups of telescopic gas rods 52. The first fixed seat 51 is built with a ventilation pipeline connected to the two groups of telescopic gas rods 52.

The two sets of fixing seats are used to cooperate with the equipment program to control the two sets of telescopic gas rods 52 to perform clamping operations;

[0036] The wire cutting machine 1 is driven by an external power supply, and the two sets of fixing seats provide compressed air through the pump air pipeline in the external workshop to drive the two sets of telescopic air rods 52 to extend or retract;

[0037] The wire cutting machine 1 is equipped with a device program, which can control the clamping and loosening of the two sets of mechanical claws, the extension and retraction of the two sets of telescopic gas rods 52, and the movement and stop of the moving seat 17;

[0038] The camera 3, the gripping robot 4, the thickness detector 43, the two sets of telescopic gas rods 52, the wire cutting machine 13, and the moving seat 17 are all connected with the equipment program signal.

[0039] Workpiece thickness detection:

[0040] When the staff needs to perform wire cutting on the workpiece, the staff first turns on the external power supply, starts the wire cutting machine 1, starts the equipment program, and then manually opens the first baffle 11 and the second baffle 12. At this time, the equipment program first detects the position of the workpiece through the camera 3, and then the equipment program controls the clamping robot 4 to clamp the workpiece. The first mechanical claw 41 clamps the workpiece and fixes it and places it on the operating table 14. During the movement of the clamping robot 4, the second mechanical claw 42 clamps the workpiece and cooperates with the thickness detector 43 to perform thickness detection operation on it. The equipment program sets the thickness value of the workpiece to X1, X2, and X3, X1 is the minimum value, and X3 is the maximum value. The processing temperature of the wire cutting machine 13 is Y1, Y2, and Y3, Y1 is the minimum value, and Y3 is the maximum value. When the setting When the equipment program detects that the thickness of the workpiece is X1, the equipment program determines that the thickness of the workpiece is thin, and the processing temperature does not need to be too high. The equipment program controls the processing temperature of the wire cutting machine 13 to be adjusted to Y1. When the equipment program detects that the thickness of the workpiece is X2, the equipment program determines that the thickness of the workpiece is slightly thick, and the processing temperature needs to be increased to ensure the wire cutting efficiency. The equipment program controls the processing temperature of the wire cutting machine 13 to be adjusted to Y2. When the equipment program detects that the thickness of the workpiece is X3, the equipment program determines that the thickness of the workpiece is thick, and the processing temperature needs to be increased to ensure the wire cutting efficiency. The equipment program controls the processing temperature of the wire cutting machine 13 to be adjusted to Y3. After the workpiece thickness detection is completed, the gripping robot 4 will place the workpiece on the operating table 14. At this time, the staff only needs to assist in confirming the position of the workpiece and make fine adjustments to proceed to the next step.

[0041] By using the clamping robot 4 in conjunction with the equipment program, there is no need for the staff to manually place the workpiece, which prevents the staff's hands from being pinched by the two sets of baffles during the placement process. During the process of picking up the workpiece, the thickness of the workpiece can be detected and the processing temperature of the wire cutting machine 13 can be adjusted to prevent the surface of the workpiece from being burned, deformed, etc. due to excessive temperature, thereby ensuring that the mechanical strength and heat resistance of the workpiece are not affected.

[0042] Workpiece clamping operations:

[0043] After completing the above operations, the staff controls the equipment program to clamp the workpiece. The equipment program controls the workshop pump air pipeline to open. Compressed air is pumped from the first fixed seat 51 into the two sets of telescopic gas rods 52. The two sets of telescopic gas rods 52 extend outward and make the clamping plate 53 fit to the surface of the workpiece. The first fixed seat 51 and the second fixed seat 6 can clamp the workpiece. The equipment program sets the compressed air pumping amount to M3, M2, and M1. M1 is the minimum value and M3 is the maximum value. It can be adjusted according to specific production needs. When the staff needs to perform wire cutting processing on small workpieces, the staff controls the workshop pump through the equipment program. The air volume of the air pipeline is M3, and the two sets of telescopic air rods 52 extend to the maximum value to clamp the workpiece. When the staff needs to perform wire cutting processing on a medium-sized workpiece, the staff controls the air volume of the workshop pump air pipeline to M2 through the equipment program, and the two sets of telescopic air rods 52 reduce the extension value to clamp the workpiece. When the staff needs to perform wire cutting processing on a large-sized workpiece, the staff controls the air volume of the workshop pump air pipeline to M1 through the equipment program, and the two sets of telescopic air rods 52 extend to the minimum value to clamp the workpiece. After completing the above operations, the staff manually closes the two sets of baffles to perform subsequent wire cutting processing operations;

[0044] By using two sets of fixing seats in conjunction with the equipment program, the appropriate clamping force can be selected according to workpieces of different lengths. There is no need to manually adjust the clamping force, which reduces the complexity of the operation. When clamping, two sets of clamping pads can reduce the wear on the workpiece, prevent damage to the workpiece during the clamping process, reduce the scrap rate of the workpiece, and reduce the factory's production costs.

[0045] Workpiece distance detection operation:

[0046] When the equipment program is performing the above-mentioned clamping operation, the equipment program detects the position of the workpiece to be clamped through the camera 3, and controls the moving seat 17 to move, thereby reducing the working stroke of the clamping robot 4. The equipment program sets the movement value of the moving seat 17 to N1, and N1 can be adjusted according to the specific needs of the staff. When the equipment program detects through the camera 3 that the workpiece to be clamped is located on the left side of the clamping robot 4, the equipment program controls the moving seat 17 to start and move to the left by a distance of N1, thereby shortening the distance between the clamping robot 4 and the operating table 14, thereby reducing the working stroke of the clamping robot 4. When the equipment program detects through the camera 3 that the workpiece to be clamped is located on the right side of the clamping robot 4, the equipment program controls the moving seat 17 to start and move to the right by a distance of N1, thereby shortening the distance between the clamping robot 4 and the operating table 14, thereby reducing the working stroke of the clamping robot 4.

[0047] By using the camera 3 in conjunction with the movable seat 17, the position of the workpiece can be detected before clamping and the distance between the clamping robot 4 and the operating table 14 can be automatically adjusted according to the position of the workpiece, thereby reducing the working stroke of the clamping robot 4 and improving the efficiency of workpiece clamping. At the same time, it can reduce the energy consumption during clamping, thereby playing a role in energy conservation and emission reduction.

[0048] Ink spraying operation:

[0049] When the equipment program is performing the above operations, the equipment program detects the clamped workpiece through the camera 3 and performs ink spraying operation on it. When the equipment program detects that the clamping robot 4 has clamped the workpiece, the equipment program controls the ink supply device in the production workshop to start, and the temperature-changing ink is sprayed from the ink nozzle 44 on the clamping robot 4 to the surface of the workpiece. The temperature-changing ink is a high-temperature color-changing ink with a color-changing range of 60°C-70°C. After the workpiece undergoes the wire cutting operation, a relatively high temperature will remain on the workpiece. At this time, the staff only needs to distinguish it by the color of the temperature-changing ink sprayed on the surface of the workpiece to prevent accidental touch and burns during the clamping process;

[0050] During the spraying process, the equipment program can spray different amounts of temperature-variable ink according to different thicknesses after the above-mentioned thickness detection, so as to prevent less ink from being sprayed on thick workpieces and affecting the observation of workers. The equipment program sets the spraying amount of the temperature-variable ink to H1, H2, and H3, where H1 is the minimum value and H3 is the maximum value. It can be adjusted according to specific production needs. When the equipment program detects that the thickness of the workpiece is X1, the equipment program controls the spraying amount of the temperature-variable ink to be H1, and sprays a small amount of temperature-variable ink from the ink nozzle 44 on the clamping robot 4 to the workpiece. The surface is prevented from being sprayed too much and dripping onto the floor of the production workshop to pollute the production environment. When the equipment program detects that the thickness of the workpiece is X2, the equipment program controls the spraying amount of the temperature-variable ink to be H2, and sprays the temperature-variable ink from the ink nozzle 44 on the clamping manipulator 4 to the surface of the workpiece. When the equipment program detects that the thickness of the workpiece is X3, the equipment program controls the spraying amount of the temperature-variable ink to be H3, and sprays a large amount of temperature-variable ink from the ink nozzle 44 on the clamping manipulator 4 to the surface of the workpiece to prevent the ink from being sprayed too little and being unfavorable to the observation of the staff.

[0051] By using the clamping robot 4 in conjunction with the ink nozzle 44, the workpiece can be marked during the clamping process, and the temperature-variable ink can be sprayed on the surface of the workpiece, so that the staff can intuitively identify whether the workpiece has a high residual temperature after cutting is completed, thereby preventing the high residual heat temperature of the workpiece from causing burns to the staff and reducing safety hazards in the production process.
