Description

Technical Field

[0001] The present invention relates to the field of laser cutting technology, and in particular to a cutting device and method for steel plate processing. Background Art

[0002] Laser cutting uses a high-power density laser beam to irradiate the material to be cut, so that the material is quickly heated to the vaporization temperature, evaporated to form holes, and as the beam moves on the material, the holes continuously form a very narrow cut, completing the cutting of the material.

[0003] The laser cutting process requires the use of supporting parts. The supporting parts support the workpiece, so that the workpiece is at a certain distance from the workbench, and there is a certain gap at the bottom of the workpiece to prevent the laser from damaging the workbench. In order to meet the cutting requirements, the supporting parts are serrated in shape to reduce the contact area with the workpiece. However, the spacing between the current supporting parts is fixed and can only meet the needs of cutting workpieces of a certain size. If the workpiece is cut smaller than the spacing, the workpiece will fall into the gap and be difficult to remove. If the supporting parts are set too densely, not only will the cost be very high, but the amount of steel slag residue on the supporting parts will also increase. It is also difficult to clean small gaps. Because the steel plate has a large area and a heavy weight, it is easy to wear against the supporting parts when placed and adjusted, which will cause scratches on the bottom of the steel plate.

[0019] Furthermore, a controller is fixed on one side of the workbench, and the controller is electrically connected to motor one, motor two and the laser cutting machine body.

[0020] A method for using a cutting device for steel plate processing comprises the following steps:

[0021] Step 1, adjusting the receiving spacing: first start the motor 1 to drive the gear 1 to rotate forward, the forward rotation of the gear 1 satisfies the direction of the one-way gear 1 to drive the rotating shaft to rotate, and then the rotating shaft drives the bevel gear 2 to rotate, the bevel gear 2 drives the bevel gear 1 and the reciprocating screw 1 to rotate, one of the reciprocating screws 1 drives the other reciprocating screw 1 to rotate through two pulleys 1 and belt 1, the rotation of the two reciprocating screws 1 makes the receiving part 1 move on the thread, the movement of the receiving part 1 will pull the spring 1, the spring 1 will pull the receiving part 2 to move, and the receiving part 2 will pull the other receiving part 2 to move on the reciprocating screw 1 through the spring 2, adjust the spacing between the receiving parts to meet the conditions for supporting the cut and formed parts, adjust the corresponding spacing according to the size of the workpiece, support the cut parts, avoid the situation where they fall into the gap and are difficult to take out, and avoid the situation where they fall and bump;

[0022] Step 2, anti-wear placement of steel plate: then start motor 1 to drive gear 1 to reverse, and the reverse rotation of gear 1 satisfies the direction of rotation of one-way gear 2 to drive reciprocating screw 2, so reciprocating screw 2 drives pulley 2 to rotate, and pulley 2 drives another reciprocating screw 2 to rotate through belt 2, and the two reciprocating screws 2 rotate at the same time through moving plate 1 to move the U-shaped support frame upward, and move to the top of the U-shaped support frame higher than the height of the receiving part 1 and the receiving part 2. At this time, the moving plate 1 also moves to the top wire tail of the reciprocating screw 2, and then the steel plate is placed on the U-shaped support frame, and the motor 1 is continued to be started to drive gear 1 to reverse, and then the moving plate 1 drives the U-shaped support frame and the steel plate to move downward, and the steel plate falls on the top of the receiving part 1 and multiple receiving parts 2. The U-shaped support frame supports the steel plate to avoid scratches caused by the excessive weight of the steel plate when it is placed on the receiving part and the collision and friction with the receiving part, and it is also convenient to separate the steel plate from the cutting workpiece during the working cutting process, and to facilitate the unloading of the formed workpiece;

[0023] Step 3: Laser cutting: Then set the cutting program through the controller and transmit the cutting program to the laser cutting machine body, which cuts the steel plate through the laser beam;

[0024] Step 4, regional workpiece laser cutting: When executing workpieces of different sizes on different areas of a steel plate at the same time, it is necessary to adjust the spacing according to the sizes of different workpieces. For example, the left side of the steel plate is cut for a large workpiece, and the right side is cut for a small workpiece. When the cutting of the large workpiece is completed, start motor 1 to drive gear 1 to reverse, so that the U-shaped support frame moves up to lift the cut steel plate. After the steel plate is lifted, the cut large workpiece still stays on the top of the receiving part, so lifting it will separate the steel plate from the large workpiece. At this time, start motor 2 to drive gear 2 to rotate forward. The forward rotation of gear 2 satisfies the direction of rotation of the one-way gear 3 to drive the reciprocating screw 3, so the reciprocating screw 3 Rotate and make the movable plate 3 push the piston rod in the piston cylinder to move, and squeeze the internal oil into the hydraulic cylinder through the pipeline. The hydraulic cylinder supports the movable plate to make it rotate around the connection point. The tilt of the movable plate will cause the receiving part and the U-shaped support frame to tilt. The friction force on the top of the U-shaped support frame keeps the steel plate stationary, while the large workpiece slides down along the slope of the receiving part. After sliding down, the reciprocating screw 3 continues to rotate to reset the movable plate 3 moved to the wire tail, and draw back the oil in the hydraulic cylinder to reset the movable plate and other structures. The separated workpieces are separated from the working area by sliding through the principle of gravity, without manual unloading, avoiding damage to labor caused by the receiving part;

[0025] Step 5, accepting spacing adjustment cutting: Then the controller starts the motor 1 to drive the gear 1 to rotate forward, and then rotates the reciprocating screw 1 to move the accepting part 1 and the accepting part 2 to one side, so that the spring 1 and the spring 2 shrink, and the accepting part 1 and the accepting part 2 move and gather at the bottom of the small workpiece area that needs to be processed, so that the spacing becomes smaller, and then the motor 1 drives the gear 1 to reverse, so that the U-shaped support frame drives the steel plate to move down, and the top of the U-shaped support frame is at the same height as the top of the accepting part, supporting one side of the steel plate, and then processing the small workpiece, automatically adjusting the acceptance spacing according to the workpiece size in different areas of the same steel plate, meeting the acceptance of workpieces of different sizes, avoiding the impact caused by the workpiece falling, and flexible use;

[0026] Step 6: Unloading: After processing, the U-shaped support frame moves up to separate the steel plate from the small workpiece, then tilts the movable plate, the small workpiece slides out, and then the steel plate is removed to complete the processing;

[0027] Step 7, cleaning: start motor 1 to drive gear 1 to rotate forward, adjust the spacing of the receiving parts to meet the specified cleaning spacing, start motor 2 to drive gear 2 to rotate reversely, so that gear 2 can drive the one-way gear 4 to drive the reciprocating screw 4 connected to it to rotate, the reciprocating screw 4 rotates through pulley 3 and belt 3 to drive another reciprocating screw 4 to rotate, the reciprocating screw 4 drives the moving plate 2 and the scraper to move, the scraper is inserted into the inner edge of the spacing to contact the receiving part, and the slag produced by cutting on the receiving part is scraped off. The slag formed on the receiving part is cleaned regularly by moving the scraper to avoid excessive accumulation affecting the accuracy of workpiece processing.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] 1. The installation adjustment mechanism of the present invention adjusts the corresponding spacing according to the size of the workpiece, supports the cut piece, avoids the situation where it falls into the gap and is difficult to take out, and also avoids the situation where it falls and bumps. It can also automatically adjust the receiving spacing according to the size of the workpieces in different areas of the same steel plate to meet the reception of workpieces of different sizes, avoid the impact caused by the workpiece falling, and is flexible to use;

[0030] 2. The present invention installs a lifting mechanism to support the steel plate, so as to avoid scratches caused by the excessive weight of the steel plate and the collision and friction with the receiving part when the steel plate is placed on the receiving part. It is also convenient to separate the steel plate from the cutting workpiece during the cutting process, and to facilitate the unloading of the formed workpiece;

[0031] 3. The mounting support unloading mechanism of the present invention uses the principle of gravity to slide the separated workpieces out of the working area, without the need for manual unloading, thus avoiding damage to the workers caused by the receiving parts;

[0032] 4. The present invention installs a slag processing mechanism to drive the scraper to move and regularly clean the slag formed on the receiving part to avoid excessive accumulation affecting the processing accuracy of the workpiece.

[0033] To sum up, the equipment has a novel design and is easy to operate. The equipment can automatically adjust the receiving spacing according to the size of workpieces in different areas of the same steel plate to meet the needs of workpieces of different sizes and avoid the impact of workpieces falling. It is flexible to use. In addition, the application has a supporting structure to drive the steel plate to move up and down, reduce scratches caused by friction when placed, and facilitate the separation of cut workpieces. The application also facilitates the unloading of workpieces without manual material removal, which is safer and more convenient. The application can also clean the receiving parts in time after processing to maintain the cutting height of the next workpiece. BRIEF DESCRIPTION OF THE DRAWINGS

[0056] A controller is fixed on one side of the workbench 11 , and the controller is electrically connected to the motor 1 41 , the motor 2 51 and the laser cutting machine body 7 .

[0057] Example 2: Reference Figure 2-5 : This embodiment provides a method for using a cutting device for steel plate processing based on embodiment 1, comprising the following steps:

[0058] Step 1, adjusting the receiving spacing: first start the motor 141 to drive the gear 142 to rotate forward, the forward rotation of the gear 142 satisfies the direction of the one-way gear 129 to drive the rotating shaft to rotate, and then the rotating shaft drives the bevel gear 210 to rotate, the bevel gear 210 drives the bevel gear 28 and the reciprocating screw 21 to rotate, one of the reciprocating screws 21 drives the other reciprocating screw 21 to rotate through two pulleys 22 and a belt 23, the rotation of the two reciprocating screws 21 causes the receiving part 25 to move on the thread, the movement of the receiving part 25 will pull the spring 126, the spring 126 will pull the receiving part 27 to move, and the receiving part 27 will pull the other receiving part 27 to move on the reciprocating screw 21 through the spring 24, adjust the spacing between the receiving parts to meet the conditions for supporting the cut and formed parts, adjust the corresponding spacing according to the size of the workpiece, support the cut parts, avoid the situation where they fall into the gap and are difficult to take out, and avoid the situation where they fall and bump;

[0059] Step 2, anti-wear placement of steel plates: Then start the motor 1 41 to drive the gear 1 42 to reverse. The reverse rotation of the gear 1 42 satisfies the direction of the one-way gear 2 34 to drive the reciprocating screw 2 31 to rotate, so the reciprocating screw 2 31 drives the pulley 2 32 to rotate, and the pulley 2 32 drives another reciprocating screw 2 31 to rotate through the belt 2 33. The two reciprocating screws 2 31 rotate at the same time through the moving plate 1 35 to move the U-shaped support frame 36 upward until the top of the U-shaped support frame 36 is higher than the height of the receiving piece 1 25 and the receiving piece 2 27. At this time, the moving plate 1 35 is also Move to the top wire tail of the reciprocating screw rod 2 31, then place the steel plate on the U-shaped support frame 36, continue to start the motor 1 41 to drive the gear 1 42 to reverse, and then make the movable plate 1 35 drive the U-shaped support frame 36 and the steel plate to move downward, and drop the steel plate on the top of the receiving part 1 25 and multiple receiving parts 2 27. The U-shaped support frame supports the steel plate to avoid scratches caused by the excessive weight of the steel plate and the collision and friction with the receiving part when the steel plate is placed on the receiving part. It is also convenient to separate the steel plate from the cutting workpiece during the working cutting process, and facilitate the unloading of the formed workpiece;

[0060] Step 3, laser cutting: Then, the cutting program is set through the controller, and the cutting program is transmitted to the laser cutting machine body 7, and the laser cutting machine body 7 cuts the steel plate through the laser beam;

[0061] Step 4, regional workpiece laser cutting: when executing workpieces of different sizes on different areas of a steel plate at the same time, it is necessary to adjust the spacing according to the sizes of different workpieces. For example, a large workpiece is cut on the left side of the steel plate, and a small workpiece is cut on the right side. When the cutting of the large workpiece is completed, start motor 1 41 to drive gear 1 42 to reverse, so that the U-shaped support frame 36 moves up to lift the cut steel plate. After the steel plate is lifted, the cut large workpiece still stays on the top of the receiving part, so lifting it will separate the steel plate from the large workpiece. At this time, start motor 2 51 to drive gear 2 52 to rotate forward. The forward rotation of gear 2 52 satisfies the direction of rotation of the one-way gear 3 18 to drive the reciprocating screw 3 17 to rotate, so the reciprocating screw 3 17 rotates and The movable plate 3 16 pushes the piston rod in the piston tube 15 to move, and the internal oil is squeezed into the hydraulic cylinder 14 through the pipeline. The hydraulic cylinder 14 supports the movable plate 12 to rotate around the connection point. The tilt of the movable plate 12 will cause the receiving part and the U-shaped support frame 36 to tilt. The friction force on the top of the U-shaped support frame 36 keeps the steel plate stationary, while the large workpiece slides down along the slope of the receiving part. After sliding down, the reciprocating screw rod 3 17 continues to rotate to reset the movable plate 3 16 moved to the wire tail, and the oil in the hydraulic cylinder 14 is drawn back to reset the movable plate 12 and other structures. The separated workpieces are separated from the working area by sliding through the principle of gravity, without manual unloading, and avoiding damage to labor caused by the receiving part;

5. A method for using a cutting device for steel plate processing, which is applicable to a cutting device for steel plate processing as claimed in any one of claims 1 to 4, characterized in that: The following steps are involved: Step 1: adjusting the receiving spacing: first, start the motor 1 (41) to drive the gear 1 (42) to rotate forward. The forward rotation of the gear 1 (42) satisfies the direction of driving the rotating shaft to rotate. Then the rotating shaft drives the bevel gear 2 (210) to rotate. The bevel gear 2 (210) drives the bevel gear 1 (28) and the reciprocating screw 1 (21) to rotate. One of the reciprocating screws 1 (21) drives the other reciprocating screw 1 (21) to rotate through two pulleys 1 (22) and belt 1 (23). The rotation of the two reciprocating screws 1 (21) causes the receiving member 1 (25) to move on the thread. The movement of the receiving member 1 (25) pulls the spring 1 (26). The spring 1 (26) pulls the receiving member 2 (27) to move. The receiving member 2 (27) pulls the other receiving member 2 (27) to move on the reciprocating screw 1 (21) through the spring 2 (24). The spacing between the receiving members is adjusted to meet the conditions for supporting the cut and formed parts. Step 2: Place the steel plate for anti-wear: Then start the motor 1 (41) to drive the gear 1 (42) to reverse. The reverse rotation of the gear 1 (42) satisfies the direction of the one-way gear 2 (34) to drive the reciprocating screw 2 (31) to rotate. Therefore, the reciprocating screw 2 (31) drives the pulley 2 (32) to rotate. The pulley 2 (32) drives another reciprocating screw 2 (31) to rotate through the belt 2 (33). The two reciprocating screws 2 (31) rotate at the same time through the moving plate 1 (35) to make the U-shaped support frame (36) on. Move until the top of the U-shaped support frame (36) is higher than the height of the receiving member 1 (25) and the receiving member 2 (27), at which time the moving plate 1 (35) also moves to the top thread tail of the reciprocating screw 2 (31), and then place the steel plate on the U-shaped support frame (36), continue to start the motor 1 (41) to drive the gear 1 (42) to reverse, and then make the moving plate 1 (35) drive the U-shaped support frame (36) and the steel plate to move downward, so that the steel plate falls on the top of the receiving member 1 (25) and the plurality of receiving members 2 (27); Step 3: Laser cutting: Then, a cutting program is set through the controller, and the cutting program is transmitted to the laser cutting machine body (7), and the laser cutting machine body (7) cuts the steel plate through a laser beam; Step 4: Regional workpiece laser cutting: When different sizes of workpieces are cut on different areas of a steel plate at the same time, the spacing needs to be adjusted according to the sizes of the workpieces. Specifically, the left side of the steel plate is cut for large workpieces, and the right side is cut for small workpieces. When the cutting of the large workpiece is completed, the motor 1 (41) is started to drive the gear 1 (42) to reverse, so that the U-shaped support frame (36) moves up to lift the cut steel plate. After the steel plate is lifted, the cut large workpiece still stays on the top of the receiving part, so lifting it will separate the steel plate from the large workpiece. At this time, the motor 2 (51) is started to drive the gear 2 (52) to rotate forward. The forward rotation of the gear 2 (52) satisfies the one-way gear 3 (18) to drive the reciprocating screw 3 (17 ) rotates, so the reciprocating screw rod three (17) rotates and causes the movable plate three (16) to push the piston rod in the piston tube (15) to move, squeezing the internal oil into the hydraulic cylinder (14) through the pipeline. The hydraulic cylinder (14) supports the movable plate (12) to rotate around the connection point. The tilt of the movable plate (12) will cause the receiving part and the U-shaped support frame (36) to tilt. The friction force at the top of the U-shaped support frame (36) keeps the steel plate stationary, while the large workpiece slides down along the slope of the receiving part. After sliding down, the reciprocating screw rod three (17) continues to rotate to reset the movable plate three (16) that has moved to the wire tail, and draws back the oil in the hydraulic cylinder (14) to reset the movable plate (12) and other structures. Step 5: Cutting by adjusting the receiving spacing: the controller then starts the motor 1 (41) to drive the gear 1 (42) to rotate forward, and then rotates the reciprocating screw 1 (21) to move the receiving part 1 (25) and the receiving part 2 (27) to one side, so that the spring 1 (26) and the spring 2 (24) contract, and the receiving part 1 (25) and the receiving part 2 (27) move and gather at the bottom of the small workpiece area to be processed, so that the spacing becomes smaller, and then the motor 1 (41) drives the gear 1 (42) to rotate reversely, so that the U-shaped support frame (36) drives the steel plate to move downward, and the top of the U-shaped support frame (36) is at the same height as the top of the receiving part, supporting one side of the steel plate, and then processing the small workpiece; Step 6, unloading: After processing, the U-shaped support frame (36) moves upward to separate the steel plate from the small workpiece, and then the movable plate (12) is tilted to slide the small workpiece out, and then the steel plate is removed to complete the processing; Step 7, cleaning: start motor 1 (41) to drive gear 1 (42) to rotate forward, adjust the receiving member spacing to meet the specified cleaning spacing, start motor 2 (51) to drive gear 2 (52) to rotate reversely, so that gear 2 (52) can drive one-way gear 4 (66) to drive reciprocating screw 4 (61) connected thereto to rotate, reciprocating screw 4 (61) rotates through pulley 3 (62) and belt 3 (63) to drive another reciprocating screw 4 (61) to rotate, reciprocating screw 4 (61) drives moving plate 2 (64) and scraper (65) to move, and scraper (65) is inserted into the inner edge of the spacing to contact the receiving member, and the steel slag produced by cutting on the receiving member is scraped off.
