Description

Technical Field

[0001] This invention relates to the field of sheet metal processing technology, specifically to a laser cutting and forming equipment for rectangular sheet metal parts. Background Technology

[0002] With increasingly fierce market competition and continuously improving market demand, laser equipment such as metal laser cutting machines has been widely used in the sheet metal processing industry and can also be applied to aluminum plate cutting, etc. Laser cutting is a high-precision processing method that uses a high-energy-density laser beam to heat the material, causing it to vaporize or melt, thereby achieving cutting. The sheet metal material of existing automotive sheet metal parts is low-carbon steel. When laser cutting equipment cuts it into rectangular sheet metal parts, the high temperature generated by the laser beam focused on the surface of the sheet metal material causes a rapid change in the temperature of the sheet metal material, resulting in thermal stress. This causes the edges of the cut rectangular sheet metal parts to easily deform, affecting the quality of the product. At the same time, a large number of sparks are generated during the laser cutting process, which can easily cause pollution and impact on the surrounding environment and is inconvenient to effectively recycle. Summary of the Invention

[0003] The technical problem solved by this solution is: (1) How to solve the problem of thermal stress caused by rapid temperature change of sheet metal material, which causes the edges of the cut rectangular sheet metal parts to be easily deformed, affecting the quality of the product; (2) How to solve the problem that a large number of sparks generated during laser cutting can easily pollute and affect the surrounding environment, and it is inconvenient to effectively recycle them.

[0004] The objective of this invention can be achieved through the following technical solution: a laser cutting and forming equipment for rectangular sheet metal parts, including a base and a fixed cover fixedly installed on its top, wherein the fixed cover is provided with a recycling mechanism for collecting sparks, and the top of the fixed cover is provided with an opening, and two guide rollers for supporting sheet metal materials are rotatably arranged on the top of the fixed cover on one side of the opening, the width of the guide rollers being greater than the width of the sheet metal materials, and a preheating mechanism for preventing deformation of the sheet metal materials is provided between the two guide rollers; The recycling mechanism includes a cylinder fixedly inserted into the base. The cylinder is arranged longitudinally, and a water storage box is fixedly installed at the extended end of the cylinder. The water storage box is located directly below the opening, and the size of the water storage box is larger than the size of the opening.

[0005] A further technical improvement of the present invention is that a return water tank and a water pump are provided on the base on one side of the cylinder, the output end of the water pump is connected to the side wall of the water storage box through a first hose, and the input end of the water pump is connected to the bottom of the return water tank through a connecting pipe.

[0006] A further technical improvement of the present invention is that: an adjusting pipe is fixedly installed on the outer wall of the return water tank, the adjusting pipe is arranged longitudinally, and a drain pipe is connected to the middle of the side of the adjusting pipe; a filter box is fixedly installed on the inner wall of the return water tank, and the output end of the drain pipe is connected to the input end of the filter box.

[0007] A further technical improvement of the present invention is that: a transmission rod is fixedly installed at the bottom of the water storage box, the bottom end of the transmission rod movably passes through the regulating pipe and is fixedly installed with a piston, and a second flexible hose is also connected to the bottom of the water storage box, the output end of the second flexible hose being connected to the top side of the regulating pipe.

[0008] A further technical improvement of the present invention is as follows: a fixed frame is fixedly installed on the top of the return water tank, and a flip plate is rotatably installed on the top of the fixed frame. One end of the flip plate is movably connected to the top of the transmission rod, and a lifting rod is longitudinally arranged on one side of the flip plate. The top end of the lifting rod movably passes through the fixed cover, and the bottom end of the lifting rod is movably connected to the other end of the flip plate. By controlling the extended end of the cylinder to extend to its maximum length, the water storage box rises to a distance of one centimeter from the fixed cover, and the water pump is turned on to facilitate the injection of clean water into the water storage box through the first hose. At this time, because the transmission rod pulls the piston to rise to block the output end of the second hose, the level of clean water in the water storage box rises. When the sheet metal material is cut by the laser cutting fixture, the generated sparks are cooled by the clean water in the water storage box to obtain debris, preventing pollution and impact on the surrounding environment. Then, the extended end of the cylinder is controlled to return to its shortest length, so that the clean water in the water storage box carries the debris into the filter box, which facilitates the effective recycling of the debris.

[0009] A further technical improvement of the present invention is that: the preheating mechanism includes a mounting plate fixedly connected to the fixed cover, a lifting plate is slidably arranged on the front side of the mounting plate via a guide rail, the bottom of the lifting plate is fixedly connected to the top of the lifting rod, and an electric heating plate is also fixedly embedded in the bottom of the lifting plate.

[0010] A further technical improvement of the present invention is that: a mounting bracket is fixedly connected to the top of the fixing cover, an L-shaped rod is rotatably provided on the top of the mounting bracket, a pressing strip for positioning sheet metal material is fixedly installed in the middle of the L-shaped rod, and a rubber block is fixedly installed at one end of the L-shaped rod.

[0011] A further technical improvement of the present invention is that: a lifting frame is fixedly installed on the top side wall of the lifting rod, and a roller is rotatably provided at the end of the lifting frame. The roller is in rolling connection with the L-shaped rod. A guide frame for guiding the lifting rod is also fixedly connected to the top of the inner wall of the fixed cover. During the extension of the cylinder's extended end, the rotating plate is driven to rotate through the transmission rod, causing the lifting rod to drive the lifting plate and the electric heating plate to descend. When the cylinder's extended end has reached half its length, the roller rolls to the middle of the L-shaped rod, and the roller drives the L-shaped rod to rotate, so that the rubber block is in close contact with one of the guide rollers. The sheet metal is then fixed in place. At this point, the sheet metal material is positioned by pressing the strip in conjunction with the guide roller. When the cylinder's extended end reaches its maximum length, the roller rolls to the end of the L-shaped rod near the rubber block. The electric heating plate then contacts the sheet metal material, preheating the portion of the sheet metal material that needs to be cut. This prevents thermal stress caused by rapid temperature changes and avoids deformation of the edges of the cut rectangular sheet metal parts. At this point, the pressing strip and guide roller provide limiting, and the conveying fixture tightens the sheet metal material to prevent dents from forming at the contact point between the sheet metal material and the electric heating plate, which would affect the preheating effect on the sheet metal material.

[0012] Compared with the prior art, the beneficial effects of the present invention are: In use, this invention involves controlling the cylinder's extended end to its maximum length, causing the water storage box to rise to a distance of one centimeter from the fixed cover. The water pump is then activated, allowing clean water to be injected into the water storage box through the first hose. Simultaneously, the transmission rod pulls the piston upwards, blocking the output end of the second hose, causing the water level in the storage box to rise. When the sheet metal material is cut using a laser cutting fixture, the resulting sparks are cooled by the water in the storage box, producing debris and preventing pollution or impact on the surrounding environment. The cylinder's extended end is then controlled to its shortest position, allowing the water in the storage box to carry the debris into the filter box for effective debris recovery.

[0013] In use, as the cylinder extends, the transmission rod drives the tilting plate to rotate, causing the lifting rod to lower the lifting plate and the electric heating plate. When the cylinder extends to half its length, the roller rolls to the middle of the L-shaped rod, causing the L-shaped rod to tilt and the rubber block to come into close contact with one of the guide rollers, thus fixing it in place. At this time, the pressing strip, in conjunction with the guide roller, positions the sheet metal material. When the cylinder extends to its maximum length, the roller rolls to the end of the L-shaped rod near the rubber block, and the electric heating plate comes into contact with the sheet metal material. The electric heating plate preheats the part of the sheet metal material that needs to be cut, preventing thermal stress caused by rapid temperature changes and avoiding deformation of the edges of the cut rectangular sheet metal parts. At this time, the pressing strip, in conjunction with the guide roller, provides a limit, and the conveying fixture tightens the sheet metal material to prevent dents from forming at the contact point between the sheet metal material and the electric heating plate, which would affect the preheating effect on the sheet metal material.

[0023] Please see Figure 3As shown, a fixed bracket 704 is fixedly installed on the top of the aforementioned return water tank 706. A flip plate 703 is rotatably mounted on the top of the fixed bracket 704. One end of the flip plate 703 is movably connected to the top of the transmission rod 713, and a lifting rod 705 is longitudinally arranged on one side of the flip plate 703. The top end of the lifting rod 705 movably passes through the fixed cover 4, and the bottom end of the lifting rod 705 is movably connected to the other end of the flip plate 703. By controlling the extended end of the cylinder 709 to extend to its maximum length, the water storage box 701 rises to a distance of one centimeter from the fixed cover 4, and the water pump 8 is turned on, facilitating... Clean water is injected into the water storage box 701 through the first hose 710. At this time, the piston is pulled up by the transmission rod 713 to block the output end of the second hose 702, causing the water level in the water storage box 701 to rise. When the sheet metal material is cut by the laser cutting fixture 1, the generated sparks are cooled by the clean water in the water storage box 701 to obtain debris, preventing pollution and impact on the surrounding environment. Then, the extended end of the cylinder 709 is controlled to return to its shortest position, so that the clean water in the water storage box 701 carries the debris into the filter box 707, which facilitates the effective recovery of the debris.

[0024] Please see Figure 2 and Figure 5 As shown, the preheating mechanism 2 includes a mounting plate 201 fixedly connected to the fixed cover 4. A lifting plate 204 is slidably provided on the front of the mounting plate 201 via a guide rail. The bottom of the lifting plate 204 is fixedly connected to the top of the lifting rod 705, and an electric heating plate 203 is also fixedly embedded in the bottom of the lifting plate 204.

[0025] Please see Figure 5 and Figure 6 As shown, the top of the aforementioned fixed cover 4 is also fixedly connected to a mounting bracket 202. An L-shaped rod 205 is rotatably mounted on the top of the mounting bracket 202. A pressing strip 207 for positioning sheet metal material is fixedly installed in the middle of the L-shaped rod 205, and a rubber block 208 is fixedly installed at one end of the L-shaped rod 205.

[0026] Please see Figure 5As shown, a lifting frame 209 is fixedly installed on the top side wall of the lifting rod 705. A roller is rotatably provided at the end of the lifting frame 209, and the roller is in rolling connection with the L-shaped rod 205. A guide frame 11 for guiding the lifting rod 705 is also fixedly connected to the top of the inner wall of the fixed cover 4. During the extension of the cylinder 709, the transmission rod 713 drives the flipping plate 703 to rotate, causing the lifting rod 705 to drive the lifting plate 204 and the electric heating plate 203 to descend. When the cylinder 709 extends to half its length, the roller rolls to the middle of the L-shaped rod 205, and the roller drives the L-shaped rod 205 to flip, so that the rubber block 208 and one of the guide rollers 6 The sheet metal is then pressed tightly against the guide roller 6 to fix it in place. At this time, the sheet metal material is positioned by pressing the strip 207 in conjunction with the guide roller 6. When the extended end of the cylinder 709 is extended to its maximum length, the roller rolls to the end of the L-shaped rod 205 near the rubber block 208. The electric heating plate 203 is in contact with the sheet metal material. The electric heating plate 203 preheats the part of the sheet metal material that needs to be cut, preventing thermal stress caused by rapid temperature changes and avoiding deformation of the edges of the cut rectangular sheet metal parts. At this time, the pressing strip 207 and the guide roller 6 provide limiting for it, and the conveying fixture 9 tightens the sheet metal material to prevent dents from occurring at the contact point between the sheet metal material and the electric heating plate 203, which would affect the preheating effect of the sheet metal material.

[0027] Please see Figure 6 As shown, a limiting block 206 is fixedly installed in the middle of the mounting bracket 202, and the end of the L-shaped rod 205 away from the rubber block 208 is fixedly connected to the limiting block 206 by a tension spring.

[0028] Please see Figure 1 and Figure 2 As shown, a trapezoidal block 10 for conveying sheet metal parts is provided above the opening 5. The bottom of the trapezoidal block 10 is fixedly connected to the inner wall of the opening 5 through a connecting rod. A laser cutting fixture 1 is provided on the fixed cover 4 on the rear side of the opening 5. The laser cutting fixture 1 is existing technology, and the output end of the laser cutting fixture 1 is facing the opening 5.

[0029] Please see Figure 2 and Figure 6 As shown, the laser cutting fixture 1 described above is provided with a conveying fixture 9 for pulling sheet metal materials on the side away from the mounting plate 201. The conveying fixture 9 is existing technology.

[0030] Working principle: When using this invention, firstly, as... Figure 1 and Figure 2 As shown, sheet metal material is placed on two guide rollers 6, and slowly conveyed by conveying fixture 9. Before the laser cutting fixture 1 starts working, as... Figure 2 and Figure 3As shown, by controlling the extension end of cylinder 709 to extend from its shortest to its longest length, the water storage box 701 rises to a distance of one centimeter from the fixed cover 4, activating the water pump 8 to allow it to inject clean water from the return water tank 706 into the water storage box 701 through the first hose 710. At this time, because the transmission rod 713 pulls the piston up to block the output end of the second hose 702, the level of clean water in the water storage box 701 rises, as... Figure 2 and Figure 3 As shown, when the sheet metal material is cut by the laser cutting fixture 1, the generated sparks penetrate the opening 5 and are cooled by the clean water in the water storage box 701 to remove debris, preventing pollution and impact on the surrounding environment. Then, the extended end of the cylinder 709 is controlled to return to its shortest position, causing the transmission rod 713 to drive the piston to slide down to the lowest position. At this time, the top wall of the piston corresponds to the position of the inlet end of the drain pipe 712, so that the clean water in the water storage box 701 carries the debris into the filter box 707, facilitating the effective recovery of the debris, while the clean water is filtered into the return water tank 706; Figures 2-4 As shown, when the extended end of cylinder 709 is at its shortest position, water pump 8 remains on, facilitating the flow of water from the first hose 710 to flush the filter box 707 and prevent the accumulation of residual debris. Figure 2 , Figure 3 and Figure 5 As shown, during the extension of the cylinder 709, the transmission rod 713 drives the tilting plate 703 to rotate, causing the lifting rod 705 to lower the lifting plate 204 and the electric heating plate 203. When the cylinder 709 extends to half its length, the roller rolls to the middle of the L-shaped rod 205, causing the L-shaped rod 205 to tilt, making the rubber block 208 tightly adhere to one of the guide rollers 6 and fix it in place. At this time, as... Figure 3 , Figure 5 and Figure 6 As shown, the sheet metal material is positioned by pressing the strip 207 in conjunction with the guide roller 6. When the extended end of the cylinder 709 reaches its maximum length, the roller rolls to the end of the L-shaped rod 205 near the rubber block 208. During this process, the L-shaped rod 205 does not rotate, and the electric heating plate 203 is in contact with the sheet metal material. The electric heating plate 203 is turned on to preheat the part of the sheet metal material that needs to be cut, preventing thermal stress caused by rapid temperature changes and avoiding deformation of the edges of the cut rectangular sheet metal parts. At this time, as... Figure 2 , Figure 5 and Figure 6 As shown, the pressing strip 207, together with the guide roller 6, provides a limit to the sheet metal material, and the conveying fixture 9 tightens the sheet metal material to prevent the contact area between the sheet metal material and the electric heating plate 203 from being dented, which would affect the preheating effect of the sheet metal material; while the cut rectangular sheet metal parts will be guided along the trapezoidal block 10 to the external collection box.
