DETAILED DESCRIPTION

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1: Please refer to Figures 1-8 This invention provides a technical solution: a cutting device for producing stainless steel parts, comprising a cutting frame 1 and a laser cutting assembly, and a lifting module. The cutting frame 1 has a guide rail 2 on its top, and the laser cutting assembly is mounted on top of the guide rail 2. A square hole 3 is formed in the top of the cutting frame 1, and a square plate 4 is fixedly installed on the inner wall of the square hole 3. A groove is formed in the top of the cutting frame 1. The lifting module includes a pressing frame 5, a fixing assembly 6, a mounting frame 7, a cutting component 8, an elastic telescopic block 9, a rotating drum frame 10, a lifting frame 11, a connecting frame 12, and an elastic telescopic rod 15. The pressing frame 5 slides through the left and right walls of the square plate 4. The fixing assembly 6 is positioned on the cutting... The inner wall of the frame 1 has a mounting frame 7 fixedly installed on the top of the cutting frame 1, the cutting part 8 is placed on the top of the mounting frame 7, the elastic telescopic block 9 is fixedly installed on the bottom of the inner wall of the groove, the rotary drum frame 10 is fixedly installed on the free end of the elastic telescopic block 9, the lifting frame 11 is slidably installed on the bottom of the inner wall of the groove, the connecting frame 12 is fixedly installed on the right side of the pressing frame 5, and the elastic telescopic rod 15 is fixedly installed on the left side of the lifting frame 11. The circumferential surface of the rotary drum frame 10 is provided with protrusions to increase the friction between it and the cutting part 8. The rotation and traction form a continuous feeding rhythm, thereby reducing the manual lifting in semi-automatic feeding and facilitating the feeding of the cutting part, thus helping to improve the cutting efficiency.

[0023] The lifting frame 11 abuts against the bottom of the rotary drum frame 10, and the lifting frame 11 contacts the connecting frame 12. The free end of the elastic telescopic rod 15 is fixedly connected to the groove. The rotary drum frame 10 moves downward to reset and disengage from the cutting part 8. The cutting part 8 is completely placed on the mounting frame. With the rigid support of the mounting frame 7, a unified cutting benchmark is established, thereby avoiding positional displacement caused by continuous contact of the rotary drum frame 10. The lifting frame 11 moves to the right to squeeze the rotary drum frame 10. The rotary drum frame 10 moves upward under the pressure of the lifting frame 11 to lift the cut part 8. If the cut part 8 is stuck on the mounting frame 7 due to thermal deformation or debris adhesion after cutting, the lifting action can force separation, avoiding the cutting process stoppage caused by material jamming, thereby ensuring the stability of continuous laser cutting production.

[0024] During operation, after placing the cutting piece 8 on the left side of the mounting frame 7, push the cutting piece 8 to the right. As the cutting piece 8 moves to the right, it contacts the rotating drum frame 10 and presses against it. The cutting piece 8, subjected to the reaction force of the rotating drum frame 10, contacts the top of the rotating drum frame 10 and is pulled by its rotation, thus reducing the friction between the cutting piece 8 and the mounting frame 7 during placement. After the cutting piece 8 is placed on top of the mounting frame 7, a linear motor is installed on the right side of the square plate 4, and the output end of the linear motor is fixedly connected to the pressing frame 5. Start the linear motor... The machine operation drives the pressing frame 5 to move to the left, making contact with the cutting part 8 and pressing and fixing it. Simultaneously, the leftward movement of the pressing frame 5 causes the connecting frame 12 to move to the left, making contact with the lifting frame 11 and pressing it. The lifting frame 11, under the pressure of the connecting frame 12, moves to the left, pressing the elastic telescopic rod 15. The elastic telescopic rod 15, under the pressure of the lifting frame 11, retracts to the left and stores force. At the same time, the lifting frame 11... The left side moves away from the rotating drum frame 10. After the rotating drum frame 10 disengages from the lifting frame 11, the elastic telescopic block 9 moves downward and resets under its own elastic force. The downward movement of the elastic telescopic block 9 causes the rotating drum frame 10 to move downward and reset, disengaging from the cutting part 8. This disengagement allows the cutting part 8 to fully contact the mounting frame 7. The laser cutting assembly is then activated to cut the cutting part 8. After the cutting of the cutting part 8 is completed, the linear motor operates to press... The frame 5 moves to the right and resets. The pressing frame 5 moves to the right and resets, which drives the connecting frame 12 to move to the right. The connecting frame 12 moves to the right and disengages from the lifting frame 11. After the lifting frame 11 disengages from the connecting frame 12, the elastic telescopic rod 15 moves to the right and resets under its own elastic force. The elastic telescopic rod 15 moves to the right and resets, which drives the lifting frame 11 to move to the right. The lifting frame 11 moves to the right and squeezes the rotating drum frame 10. The rotating drum frame 10 moves upward under the squeeze of the lifting frame 11 and lifts the cut piece 8.

[0025] Example 2: Please refer to Figures 1-8Based on Embodiment 1, this embodiment further includes a protection module and a limiting module. The protection module is used to prevent the cutting part 8 from warping after cutting, and the limiting module is used to limit the tightening force on the cutting part 8. The protection module includes a protection frame 131, a protection spring 132, a V-shaped plate 133, a return spring 134, and a hollow frame 135. The protection frame 131 is slidably installed at the bottom of the mounting frame 7. The protection spring 132 is disposed between the protection frame 131 and the mounting frame 7. The V-shaped plate 133 is slidably installed on the inner wall of the protection frame 131. The return spring 134 is disposed between the V-shaped plate 133 and the protection frame 131. The hollow frame 135 is fixedly installed on the top of the protection frame 131. The inclined surface of the V-shaped plate 133 can adapt to cutting parts 8 with different cross-sections. The elastic force of the return spring 134 provides continuous and moderate pressure to avoid displacement caused by vibration during the cutting process.

[0026] The protective module also includes a hollow plate 136 and a detection groove 137. The hollow plate 136 is slidably installed on the inner wall of the hollow frame 135, and the detection groove 137 is opened on the top of the mounting frame 7. If the position of the cutting part 8 is misaligned, it can be observed by the fact that the hollow plate 136 is not completely in contact with the detection groove 137. The deviation can be detected in time before the first piece is cut by manual observation of the fitting gap, so as to avoid the batch cutting parts 8 being out of tolerance due to feeding errors.

[0027] The bottom of the hollow plate 136 is set as an arc surface. The arc surface at the bottom of the hollow plate 136 can reduce the friction when the hollow plate 136 contacts the cutting part 8. A spring is set between the hollow frame 135 and the hollow plate 136. The spring can support the hollow plate 136. The left side of the V-shaped plate 133 is set as an inclined surface.

[0028] The limiting module includes a hollow frame 141, a displacement plate 142, a displacement ring 143, a limiting plate 144, a curved spring sheet 145, and a limiting hole 146. The hollow frame 141 is fixedly installed on the top of the pressing frame 5. The displacement plate 142 is slidably installed on the inner wall of the hollow frame 141. The displacement ring 143 is located between the hollow frame 141 and the displacement plate 142. The limiting plate 144 is slidably installed on the inner wall of the hollow frame 141. The curved spring sheet 145 is located between the hollow frame 141 and the limiting plate 144. The limiting hole 146 is opened on the top of the mounting frame 7. The limiting plate 144 can accurately control the maximum stroke of the pressing frame 5 to prevent the cutting part 8 from undergoing irreversible plastic deformation due to excessive fastening force, thereby reducing the scrap of appearance or size.

[0029] The hollow frame 141 is filled with gas. A rubber ring is provided between the hollow frame 141 and the displacement plate 142. The rubber ring can improve the sealing between the hollow frame 141 and the displacement plate 142. A sealing ring is provided between the hollow frame 141 and the limiting plate 144. The sealing ring can improve the sealing between the hollow frame 141 and the limiting plate 144.

[0030] The bottom of the limiting plate 144 is set as an inclined surface, which makes it easy for the limiting plate 144 to be reset. The displacement plate 142 penetrates the top of the protective frame 131 and contacts the V-shaped plate 133. The limiting plate 144 abuts against the mounting frame 7.

[0031] During operation, the pressing frame 5 moves to the left and contacts the protective frame 131, squeezing it. The protective frame 131, squeezed by the pressing frame 5, moves to the left, pulling on the protective spring 132. The protective spring 132 deforms and stores force due to this pulling. Simultaneously, the leftward movement of the protective frame 131 causes the V-shaped plate 133 to move, contacting and squeezing the cutting piece 8. The reaction force from squeezing the cutting piece 8 causes the V-shaped plate 133 to move upward, squeezing the return spring 134. The return spring 134, squeezed by the V-shaped plate 133, generates... The V-shaped plate 133, in conjunction with the spring force of the return spring 134, presses down on the top of the cutting piece 8. At the same time, the protective frame 131 moves to the left, causing the hollow frame 135 to move. The hollow frame 135 moves, causing the hollow plate 136 to move to the left. The hollow plate 136 moves to the left and contacts the detection groove 137, squeezing the detection groove 137. If the cutting piece 8 is positioned correctly, the hollow plate 136 will be completely in contact with the detection groove 137. If the cutting piece 8 is misaligned, it can be observed that the hollow plate 136 is not completely in contact with the detection groove 137. Once it is observed that the hollow plate 136 is not completely in contact with the detection groove 137, the position of the misaligned cutting piece 8 can be adjusted.

[0032] The V-shaped plate 133 moves upward and contacts the displacement plate 142, pressing it. The displacement plate 142 moves upward under the pressure of the V-shaped plate 133, pressing the displacement ring 143. The displacement ring 143 deforms and stores force under the pressure of the displacement plate 142. At the same time, the upward movement of the displacement plate 142 compresses the gas inside the hollow frame 141. The gas inside the hollow frame 141 moves towards the curved spring piece 145 under the pressure of the displacement plate 142. The gas inside the hollow frame 141 compresses the limiting plate 144 under the pressure of the gas inside the hollow frame 141. The limiting plate 144 moves downward under the pressure of the gas inside the hollow frame 141. The downward movement of the limiting plate 144 causes it to contact the limiting hole 146 and limit the pressing frame 5. The pressing frame 5 is limited by the limitation of the limiting plate 144, thus restricting the fastening force on the cutting part 8.
