Description

Technical Field

[0001] This invention belongs to the field of metal parts cutting technology, specifically a stainless steel sheet cutting device. Background Technology

[0002] Laser cutting of stainless steel metal parts is an advanced processing technology. When cutting stainless steel metal parts, a whole piece of stainless steel metal sheet is usually placed on a laser cutting machine, and the laser cutting head cuts metal parts of different required shapes from the stainless steel metal sheet. It has the characteristics of high processing accuracy, high efficiency and good cutting quality.

[0003] Patent CN118951410A discloses a laser cutting device for metal processing, including a laser cutting machine body. A conveying component is installed inside the laser cutting machine body, and a fixing component is installed on the conveying component. Two sets of horizontal rails are symmetrically arranged on the laser cutting machine body, and the two sets of horizontal rails are slidably connected to a slide rail. A cutting head is installed on the slide rail. The fixing component includes two sets of connecting plates, multiple sets of support plates, rotating rollers, and other components. The conveying component is used to transport the cut metal parts to the next process. This solution fixes the metal sheet with the fixing component. Since the metal sheet is located above the conveyor belt of the conveying component, the cut parts will fall directly onto the conveyor belt of the conveying component, which is convenient for workers to collect the parts.

[0004] In the above-mentioned scheme, the metal sheet needs to be fixed before cutting. After the metal sheet is cut, a series of operations are required to make the waste material fall onto the conveying component before the next set of metal sheets can be cut. The fixing of the metal sheet and the recycling of the waste material are relatively troublesome, wasting a lot of time and making it impossible to continuously cut the metal sheet, thus reducing the efficiency of parts cutting. Therefore, the present invention provides a stainless steel metal sheet cutting device. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by the present invention to solve its technical problem is as follows: The stainless steel sheet cutting equipment of the present invention includes a frame, a conveying mechanism for conveying stainless steel sheets is provided inside the frame, an XY axis transport mechanism is installed on the frame, a laser cutting head is installed on the XY axis transport mechanism, the conveying mechanism includes two sets of drive shafts, the two sets of drive shafts are symmetrically rotated and installed in the frame, each end of the drive shaft is provided with a sprocket, the chain meshes with the two sets of sprockets, a number of cutting tables are arranged around the two sets of chains, the end of the cutting table is fixedly connected to the chain, and the cutting table is provided with a placement groove for placing stainless steel sheets; By driving several sets of cutting tables to make circular motion, each set of cutting tables can pass through the feeding point, the area below the XY axis conveying mechanism, and the unloading point. This allows the operator to simultaneously feed stainless steel sheets and unload metal parts and scrap materials during the stainless steel sheet cutting process, thereby enabling continuous cutting of stainless steel sheets and improving the efficiency of parts cutting.

[0007] Preferably, a waste box for placing metal scrap is provided between several sets of cutting tables, and both ends of the waste box are fixedly connected to the inner wall of the frame; The metal shavings generated during cutting will fall directly into the waste bin, thus achieving the recycling of metal shavings.

[0008] Preferably, the cutting table includes a frame, with two sets of chains connected to each end of the frame. A support platform for holding the stainless steel sheet is installed in the inner ring of the frame. Two sets of first limiting strips are movably installed on the frame, facing each other. Two sets of second limiting strips are also movably installed on the frame, facing each other. One side of each first limiting strip is fixedly connected to one end of two sets of U-shaped elastic strips, and the other end of the U-shaped elastic strips is fixedly connected to the edge of the frame. The two sets of first limiting strips, the two sets of second limiting strips, and the support platform together form a placement groove. Four sets of first guide grooves are provided on the frame. Two sets of first guide rails are fixedly connected to the lower end face of the positioning bar. The first guide rails are slidably connected to the first guide groove. Four sets of second guide grooves are also provided on the frame. Two sets of second guide rails are fixedly connected to the lower end face of the second positioning bar. The second guide rails are slidably connected to the second guide groove. A receiving plate is fixedly connected to the middle of one side of the first positioning bar. A roller is rotatably installed at the end of the receiving plate. Pushing blocks for pushing the rollers are provided on both sides inside the XY axis conveying mechanism. L-shaped rods are provided at both ends of the first positioning bar. A pin is provided at the end of the L-shaped rod. An oblique sliding groove is provided on the second guide rail. The pin is located in the oblique sliding groove. The rollers push the receiving plate, along with the first limiting strip, toward the stainless steel sheet. The first limiting strip stretches two sets of U-shaped elastic strips. Simultaneously, the first limiting strip drives the pin shaft to slide along the inclined slide groove via the L-shaped rod, causing the second guide rail to move along the second guide groove and simultaneously move the second limiting strip toward the stainless steel sheet until the two sets of first and second limiting strips are in a merged state. This corrects the position of the stainless steel sheet and ensures the accuracy of the laser cutting head cutting parts on the stainless steel sheet. After cutting, the cutting table continues to move, and the rollers will displace the push block. Under the rebound force of the U-shaped elastic strips, the two sets of first and second limiting strips return to a separated state. This not only makes it easier for workers to remove the waste material but also makes it easier for workers to place the stainless steel sheet into the placement groove.

[0009] Preferably, the support platform includes a receiving frame, which is movably installed below the frame. Several sets of triangular strips are installed in the inner circle of the receiving frame. Receiving brackets are fixedly installed at both ends of the lower part of the receiving frame. A spring is provided above the receiving bracket. The lower end of the spring is fixedly connected to the receiving bracket, and the upper end of the spring is fixedly connected to the frame. Four sets of through holes are opened at the four corners of the receiving frame. The through holes are slidably connected to guide posts. The upper end of the guide posts is fixedly connected to the frame. A pulley is rotatably installed at one end of the receiving bracket. Fixing strips are installed on both sides inside the frame. Several sets of teeth are provided on the fixing strips for pushing the pulley. Because the fixing strip has multiple teeth, the stainless steel sheet vibrates continuously. This continuous vibration causes the parts to detach from the scrap material in advance, making it faster and easier for workers to shake the scrap material and remove the parts.

[0010] The beneficial effects of this invention are as follows: 1. By driving several sets of cutting tables to make circular motion, each set of cutting tables can pass through the feeding point, the area below the XY axis conveying mechanism, and the unloading point. This allows the operator to simultaneously feed stainless steel sheets and unload metal parts and scrap materials during the stainless steel sheet cutting process, thereby enabling continuous cutting of stainless steel sheets and improving the efficiency of parts cutting.

[0011] 2. When the cutting table carrying the stainless steel sheet moves to the XY axis conveying mechanism, the two sets of rollers on the cutting table are squeezed by the two sets of push blocks, causing the rollers to push the receiving plate and the first limiting strip towards the stainless steel sheet. At the same time, the first limiting strip stretches the two sets of U-shaped spring strips. Simultaneously, the first limiting strip drives the pin to slide along the inclined slide groove through the L-shaped rod, causing the second guide rail to move along the second guide groove and drive the second limiting strip towards the stainless steel sheet synchronously until the two sets of first limiting strips and the two sets of second limiting strips are in a combined state, realizing the correction of the position of the stainless steel sheet and ensuring the accuracy of the laser cutting head cutting parts on the stainless steel sheet. After the cutting is completed, the cutting table continues to move, and the rollers will be offset from the push blocks. Under the rebound force of the U-shaped spring strips, the two sets of first limiting strips and the two sets of second limiting strips return to a separated state. This not only makes it easier for the staff to remove the waste material, but also makes it easier for the staff to place the stainless steel sheet into the placement groove.

[0012] 3. After the stainless steel sheet is cut, the cutting table moves towards the unloading point. During this process, the two sets of first and second limit bars return to their separated state, and the two sets of pulleys are squeezed by the teeth on the fixed bar. This causes the pulleys to drive the receiving frame, along with the receiving frame and the triangular strip, downwards. The receiving frame also stretches the spring, and the stainless steel sheet moves downwards along with the triangular strip until the pulleys disengage from the teeth of the fixed bar. Under the spring's rebound force, the receiving frame, along with the receiving frame, the triangular strip, and the stainless steel sheet, moves upwards until the receiving frame hits the lower end of the frame, causing the stainless steel sheet to vibrate. Because the fixed bar has multiple teeth, the stainless steel sheet vibrates continuously. This continuous vibration causes the parts to detach from the scrap material earlier, making it faster and easier for workers to shake the scrap material and remove the parts.

Detailed Implementation

[0023] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0024] Example 1: As Figures 1 to 3 As shown in the embodiment of the present invention, a stainless steel sheet cutting device includes a frame 1. A conveying mechanism 2 for conveying stainless steel sheets 6 is provided inside the frame 1. An XY axis transport mechanism 3 is installed on the frame 1. A laser cutting head 4 is installed on the XY axis transport mechanism 3. The conveying mechanism 2 includes two sets of drive shafts 201. The two sets of drive shafts 201 are symmetrically rotated and installed inside the frame 1. Both ends of the drive shafts 201 are provided with sprockets 202. Chains 203 mesh with the two sets of sprockets 202. Several sets of cutting tables 204 are arranged around the two sets of chains 203. The ends of the cutting tables 204 are fixedly connected to the chains 203. The cutting tables 204 are provided with placement slots 41 for placing stainless steel sheets 6.

[0025] Specifically, the XY-axis conveying mechanism 3 adopts a synchronous belt drive mechanism in the prior art. When stainless steel metal parts need to be cut, a set of stainless steel sheets 6 are placed on the cutting table 204 at the feeding point, and the stainless steel sheets 6 are located in the placement groove 41. Figure 2 The arrow indicates the material feeding point. Next, a motor drives a set of drive shafts 201 to rotate. These drive shafts 201 rotate two sets of sprockets 202, which in turn drive two sets of chains 203 and several sets of cutting tables 204 in a circular motion. The XY-axis transport mechanism 3 moves towards the attached... Figure 1The middle arrow indicates the direction of circular motion until the cutting table 204 carrying the stainless steel sheet 6 moves below the XY-axis transport mechanism 3. Through the cooperation of the XY-axis transport mechanism 3 and the laser cutting head 4, metal parts of different required shapes are cut from the stainless steel sheet 6. During the cutting process, the stainless steel sheet 6 can be placed onto the next set of cutting tables 204. After cutting is completed, several sets of cutting tables 204 continue to be driven in circular motion, causing the next set of cutting tables 204 carrying the stainless steel sheet 6 to move below the XY-axis transport mechanism 3. The processed stainless steel sheet 6 then moves to the unloading point. Figure 1 The middle arrow indicates the unloading point. During the cutting process of the laser cutting head 4 on the next set of stainless steel sheets 6, the operator can remove the metal parts and scrap material from the cutting table 204 at the unloading point, and place the stainless steel sheet 6 on the cutting table 204 at the feeding point. After the stainless steel sheet 6 is cut, the above operation is repeated. Compared with the existing technology, by driving several sets of cutting tables 204 to make circular motion, the cutting tables 204 can pass through the feeding point, the XY axis conveying mechanism 3, and the unloading point one by one. This allows the operator to simultaneously feed the stainless steel sheet 6 and unload the metal parts and scrap material during the stainless steel sheet 6 cutting process, thereby realizing continuous cutting of the stainless steel sheet 6 and improving the efficiency of parts cutting.

[0026] Furthermore, a scrap box 5 for placing metal scrap is provided between several sets of cutting tables 204, and both ends of the scrap box 5 are fixedly connected to the inner wall of the frame 1.

[0027] Specifically, when the stainless steel sheet 6 is cut, the metal scraps generated during cutting will fall directly into the waste box 5, thus achieving the recycling of the metal scraps.

[0028] like Figures 4 to 6As shown, the cutting table 204 includes a frame 2041, with two sets of chains 203 connected to both ends of the frame 2041. A support platform 2042 for holding the stainless steel sheet 6 is installed in the inner ring of the frame 2041. Two sets of first limiting strips 2043 are movably installed on the frame 2041, facing each other. Two sets of second limiting strips 2044 are movably installed on the frame 2041, facing each other. One side of each of the first limiting strips 2043 is fixedly connected to one end of two sets of U-shaped elastic strips 2045, and the other end of each U-shaped elastic strip 2045 is fixedly connected to the edge of the frame 2041. The two sets of first limiting strips 2043, the two sets of second limiting strips 2044, and the support platform 2042 together form a placement groove 41. Four sets of first guide grooves 411 are provided on the frame 2041. Two sets of first guide rails 431 are fixedly connected to the lower end face of the limiting strip 2043. The first guide rails 431 are slidably connected to the first guide groove 411. Four sets of second guide grooves 412 are also provided on the frame 2041. Two sets of second guide rails 441 are fixedly connected to the lower end face of the second limiting strip 2044. The second guide rails 441 are slidably connected to the second guide grooves 412. A receiving plate 2046 is fixedly connected to the middle of one side of the first limiting strip 2043. A roller 2047 is rotatably installed at the end of the receiving plate 2046. Pushing blocks 301 for pushing the roller 2047 are provided on both sides of the XY axis conveying mechanism 3. L-shaped rods 432 are provided at both ends of the first limiting strip 2043. A pin 433 is provided at the end of the L-shaped rod 432. An inclined sliding groove 442 is provided on the second guide rail 441. The pin 433 is located in the inclined sliding groove 442.

[0029] Specifically, to ensure the accuracy of part cutting, the stainless steel sheet 6 and the placement groove 41 are fitted tightly. Since the stainless steel sheet 6 is typically cut, burrs may remain on its edges, making it difficult to place it into the placement groove 41. Furthermore, the thermal expansion and contraction of the stainless steel sheet 6 after cutting increases the difficulty for workers to remove the waste material from the placement groove 41. When the cutting table 204 is at the unloading point, the two sets of first limiting strips 2043 and two sets of second limiting strips 2044 are separated. The volume of the placement groove 41 formed by the two sets of first limiting strips 2043, two sets of second limiting strips 2044, and the support platform 2042 is larger than the volume of the stainless steel sheet 6, allowing workers to quickly and easily place the stainless steel sheet 6 into the placement groove 41. When the cutting table 204 carrying the stainless steel sheet 6 moves to below the XY axis conveying mechanism 3, the two sets of rollers 2047 on the cutting table 204 are respectively squeezed by the two sets of push blocks 301, causing the rollers 2047 to push the receiving plate. 2046, together with the first limiting strip 2043, moves towards the stainless steel sheet 6. The first limiting strip 2043 stretches the two sets of U-shaped elastic strips 2045. Simultaneously, the first limiting strip 2043, via the L-shaped rod 432, drives the pin 433 to slide along the inclined slide groove 442, causing the second guide rail 441 to move along the second guide groove 412, simultaneously moving the second limiting strip 2044 towards the stainless steel sheet 6, until the two sets of first limiting strips 2043 and the two sets of second limiting strips 2044 are in a combined state. The position of the stainless steel sheet 6 is corrected to ensure the accuracy of the laser cutting head 4 in cutting parts on the stainless steel sheet 6. After the cutting is completed, the cutting table 204 continues to move, and the roller 2047 will be offset from the push block 301. Under the rebound force of the U-shaped spring strip 2045, the two sets of first limit strips 2043 and two sets of second limit strips 2044 return to the separated state. This not only makes it easier for the staff to remove the waste material, but also makes it easier for the staff to place the stainless steel sheet 6 into the placement groove 41.

[0030] Example 2: Figure 7 and Figure 8 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: the support platform 2042 includes a receiving frame 421, which is movably installed below the frame 2041. Several sets of triangular strips 422 are installed in the inner circle of the receiving frame 421. The receiving frame 421 is fixedly installed at both ends below the receiving frame 421. A spring 424 is provided above the receiving frame 423. The lower end of the spring 424 is fixedly connected to the receiving frame 423, and the upper end of the spring 424 is fixedly connected to the frame 2041. Four sets of through holes 21 are opened at the four corners of the receiving frame 421. The through holes 21 are slidably connected to the guide post 22. The upper end of the guide post 22 is fixedly connected to the frame 2041. A pulley 425 is rotatably installed at one end of the receiving frame 423. Fixing strips 101 are installed on both sides inside the frame 1. Several sets of teeth 102 for pushing the pulley 425 are provided on the fixing strips 101.

[0031] Specifically, after the stainless steel sheet 6 is cut by the laser cutting head 4, the cut parts will get stuck on the scrap material due to thermal expansion and contraction. When the worker removes the parts, the worker needs to shake the scrap material first. Because the parts are stuck on the scrap material, shaking is time-consuming and laborious, thus increasing the difficulty of removing the parts. After the stainless steel sheet 6 is cut, the cutting table 204 will move towards the unloading point. During this process, the two sets of first limit bars 2043 and the two sets of second limit bars 2044 return to the separated state, and the two sets of pulleys 425 will be squeezed by the teeth 102 on the fixing bar 101, causing the pulleys 425 to drive the receiving frame 423 together with the receiving frame 421 and the triangular strip 422 towards the unloading point. The receiving frame 423 moves downward, and the tension spring 424 is stretched. At the same time, the stainless steel sheet 6 moves downward together with the triangular strip 422 until the pulley 425 misaligns with the teeth 102 of the fixing strip 101. Under the rebound force of the spring 424, the receiving frame 423, together with the receiving frame 421, the triangular strip 422, and the stainless steel sheet 6, moves upward until the receiving frame 421 hits the lower end face of the frame 2041, causing the stainless steel sheet 6 to vibrate. Since the fixing strip 101 has multiple teeth 102, the stainless steel sheet 6 vibrates continuously. Through continuous vibration, the parts are separated from the scrap material in advance, making it faster and easier for workers to shake the scrap material and parts.

[0032] Working principle: A set of stainless steel sheets 6 is placed on the cutting table 204 at the feeding point, and the stainless steel sheets 6 are located in the placement groove 41. Figure 2 The arrow indicates the material feeding point. Next, a motor drives a set of drive shafts 201 to rotate. These drive shafts 201 rotate two sets of sprockets 202, which in turn drive two sets of chains 203 and several sets of cutting tables 204 in a circular motion. The XY-axis transport mechanism 3 moves towards the attached... Figure 1 The middle arrow indicates the direction of circular motion until the cutting table 204 carrying the stainless steel sheet 6 moves below the XY-axis transport mechanism 3. Through the cooperation of the XY-axis transport mechanism 3 and the laser cutting head 4, metal parts of different required shapes are cut from the stainless steel sheet 6. During the cutting process, the stainless steel sheet 6 can be placed onto the next set of cutting tables 204. After cutting is completed, several sets of cutting tables 204 continue to be driven in circular motion, causing the next set of cutting tables 204 carrying the stainless steel sheet 6 to move below the XY-axis transport mechanism 3. The processed stainless steel sheet 6 then moves to the unloading point. Figure 1 The middle arrow indicates the unloading point. During the process of the laser cutting head 4 cutting the next set of stainless steel sheets 6, the operator can remove the metal parts and waste material at the unloading point from the cutting table 204, and at the same time place the stainless steel sheet 6 on the cutting table 204 at the unloading point. After the stainless steel sheet 6 is cut, the above operation is repeated. When the cutting table 204 is at the unloading point, the two sets of first limiting bars 2043 and two sets of second limiting bars 2044 are in a separated state. The two sets of first limiting bars 2043, two sets of second limiting bars 2044, and the support platform 2042 together form a placement groove 41 with a volume larger than the volume of the stainless steel sheet 6, allowing the operator to quickly and easily place the stainless steel sheet 6 into the placement groove 41. When the cutting table 204 carrying the stainless steel sheet 6 moves to below the XY axis conveying mechanism 3, the two sets of rollers 2047 on the cutting table 204 are squeezed by the two sets of push blocks 301, causing the rollers 2047 to push the receiving plate 2046 along with the first limiting bars 2043 toward the stainless steel sheet 6, and the first limiting bars 2043 stretch the two sets of U-shaped bars 2044. The U-shaped spring bar 2045, and the first limiting bar 2043, through the L-shaped rod 432, drives the pin 433 to slide along the inclined slide groove 442, so that the second guide rail 441 drives the second limiting bar 2044 to move synchronously towards the stainless steel sheet 6 along the second guide groove 412, until the two sets of first limiting bars 2043 and two sets of second limiting bars 2044 are in a merged state, so as to correct the position of the stainless steel sheet 6 and ensure the accuracy of the laser cutting head 4 in cutting parts on the stainless steel sheet 6. After the cutting is completed, the cutting table 204 continues to move, and the roller 2047 will be offset from the push block 301. Under the rebound force of the U-shaped spring bar 2045, the two sets of first limiting bars 2043 and two sets of second limiting bars 2044 return to the separated state. After the stainless steel sheet 6 is cut, the cutting table 204 moves towards the unloading point. During this process, the two sets of first limiting bars 2043 and the two sets of second limiting bars 2044 return to the separated state, and the two sets of pulleys 425 are squeezed by the teeth 102 on the fixing bar 101, causing the pulleys 425 to drive the receiving frame 423, along with the receiving frame 421 and the triangular strip 422, to move downwards. At the same time, the receiving frame 423 stretches the spring 424, and the stainless steel sheet 6 moves downwards along with the triangular strip 422. 22 moves downward together until the pulley 425 is misaligned with the teeth 102 of the fixing strip 101. Under the rebound force of the spring 424, the receiving frame 423, together with the receiving frame 421, the triangular strip 422, and the stainless steel sheet 6, moves upward until the receiving frame 421 hits the lower end face of the frame 2041, causing the stainless steel sheet 6 to vibrate. Since the fixing strip 101 has multiple teeth 102, the stainless steel sheet 6 vibrates continuously. Through continuous vibration, the parts are separated from the scrap material in advance.
