Description

Technical Field

[0001] This invention relates to the field of metal cutting technology, specifically a cutting machine for the production of stainless steel products. Background Technology

[0002] Cutting machines for stainless steel product manufacturing are specialized blanking equipment in stainless steel processing production lines. They are mainly used for cutting stainless steel plates, pipes, and profiles. They rely on mechanical cutting tools to separate the workpieces. Equipped with a cooling system, they suppress the cutting heat during stainless steel processing. Different cutting methods such as band saws, cold cutting saws, and milling can be selected according to the shape of the workpiece. The scissor-type band saw uses a feed method where the saw frame swings around the hinge axis. It relies on the continuous cyclic cutting motion of the ring saw blade to complete the workpiece cutting. It performs cutting processing on metal profiles, pipes, and bars.

[0003] To reduce the time wasted on single-pipe cutting and improve overall production efficiency, the production end often uses a multi-pipe stacking and clamping method for centralized sawing. Since stainless steel pipes generally have thin walls, if the clamping mechanism applies a large clamping load, the pipe wall will undergo plastic indentation deformation that is difficult to recover. Conversely, if the clamping pressure is set too low, the pipe is prone to axial movement during sawing. The steel pipes in the middle layer of the stacked structure have a higher risk of movement than the outer pipes. The moving steel pipes will apply lateral loads to the high-speed saw blade, continuously interfering with the saw blade's running trajectory and tension stability. This can cause the saw blade to fall off, affecting production, or even cause the saw blade to break due to a sudden increase in lateral alternating stress, resulting in safety risks. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a cutting machine for the production of stainless steel products, including a machine base, a saw frame rotatably connected to the top of the machine base, a slide table slidably connected to the top of the machine base, and further comprising:

[0021] Preferably, the locking assembly includes a plurality of latching blocks rotatably connected to the outer wall of the fixed housing, and the inner walls of the plurality of latching blocks are all fixedly connected with torsion springs;

[0022] The side of the torsion spring furthest from the locking block is fixedly connected to the fixed shell;

[0023] There are two locking blocks, which are set in a mirror image. The torsion spring has a certain elastic potential energy in its initial state, which drives the side of the locking block away from the torsion spring to be pressed tightly against the rotating shaft. The locking blocks are made of wear-resistant metal.

[0024] Preferably, the gear assembly includes a second gear rotatably connected to the outer wall of the fixed block;

[0025] Among them, gear two meshes with gear one;

[0026] Two gears are rotatably connected to the outer walls of the two fixed blocks near the rotating shaft on their adjacent sides, and the two gears mesh with the two gears.

[0027] Preferably, the sliding assembly includes a movable rod fixedly connected to the outer wall of the fixed block;

[0028] The movable rod connects two fixed blocks that are arranged opposite to each other in a set;

[0029] In a set of two opposing sliding blocks, a moving rod is fixedly connected to the side of each other. There are a total of six moving rods. The three moving rods closest to the block are perpendicular to the other three moving rods. The six moving rods are divided into two groups, with the three moving rods in each group arranged in a linear array.

[0030] Preferably, the linkage assembly includes a drive rod fixedly connected to the outer wall of the second gear, a long connecting rod rotatably connected to the side of the drive rod away from the second gear, and a short connecting rod rotatably connected to the side of the long connecting rod away from the drive rod.

[0031] Among them, the long connecting rod is rotatably connected to the outer wall of the sliding block near the fixed block, and the short connecting rod is rotatably connected to the outer wall of the sliding block away from the fixed block;

[0032] The long connecting rod is twice the length of the drive rod and the short connecting rod, and the drive rod, the long connecting rod, and the short connecting rod are all located on the side closest to the rotation axis.

[0033] Preferably, the friction assembly includes a rubber pad fixedly connected to the outer wall of the fixed rod;

[0034] The rubber pad is made of hard rubber and is tapered when it is not in contact with the stainless steel pipe, with the larger diameter part close to the moving block.

[0035] Preferably, the support assembly includes several spring pieces fixedly connected to the outer wall of the fixed rod, and a protective plate is fixedly connected to the outer wall of the movable block;

[0036] The protective sheet is located at the smaller diameter end of the rubber pad;

[0037] There are four spring clips arranged in a circular array. The side of the spring clip away from the fixing rod is fixedly connected to the rubber pad. The rubber pad is in a free state when it is not in contact with the stainless steel pipe.

[0038] The present invention has the following beneficial effects:

[0039] (1) The present invention utilizes the method of pushing the stainless steel pipe towards the fixed shell so that the pipe contacts the rubber pad. During the continuous pushing process, the inner wall of the pipe presses the rubber pad and causes the spring to deform. The spring accumulates elastic potential energy. After the pipe contacts the moving block, it reaches the designated position. Under the influence of its own elastic potential energy, the spring applies strong pressure to the inner wall of the pipe and presses the rubber pad tightly against the inner wall of the pipe, thereby restricting the axial movement of the pipe. Through the application of the above components, the problem of insufficient clamping force when cutting stacked stainless steel pipes, which causes the stainless steel pipe to move during the cutting process, and the pipe to apply lateral load to the saw blade, causing the saw blade to fall off or even break.

[0040] (2) This invention utilizes the feature of the above-mentioned device where the spring sheet squeezes the rubber pad tightly against the pipe. When the spring sheet squeezes the rubber pad tightly against the inner wall of the pipe, the pipe is fixed, which reduces the pipe axis movement. After fixing the end of the pipe, the vibration of the pipe during cutting is reduced. At this time, the spring sheet can still undergo slight deformation, which can absorb the high-frequency fine vibration generated by cutting. This alleviates the problem of resonance during cutting when the pipe is completely fixed, which causes vibration marks on the cutting surface. After the pipe is cut, the stress released by the pipe is transmitted to the rubber pad and the spring sheet, which absorbs the released stress and reduces the jumping amplitude of the pipe. Through the application of the above components, the problem of vibration at the protruding end during pipe cutting, which causes the pipe to repeatedly clamp and release the saw blade, resulting in saw blade damage and burrs on the pipe is effectively alleviated. At the same time, the problem of sudden stress release when the pipe is broken, which causes the pipe to jump and collide with other pipes is also alleviated.

[0041] (3) This invention utilizes the characteristics of the rubber pad in contact with the pipe of the above-mentioned equipment. By setting a protective plate, when the pipe approaches the rubber pad, it will first contact the protective plate. At this time, after squeezing the protective plate, the protective plate will first squeeze the rubber pad, reducing the taper of the rubber pad, thereby reducing the area of ​​the rubber pad in contact with the pipe. When the pipe passes the rubber pad, the pipe has just pressed the spring, so the rubber pad has shrunk to the size of the inner wall diameter of the pipe. Through the application of the above components, the problem of burrs on the pipe cutting surface being scratched by the burrs during the next cut, resulting in a reduction in the life of the rubber pad, is effectively alleviated.

[0042] (4) The present invention utilizes the feature of the rotating shaft of the above-mentioned device. When the shaft is rotated, the distance between the fixed block and the sliding block can be adjusted, thereby changing the distance between the moving rods. This causes the moving blocks to change their positions in both the vertical and horizontal directions, thus changing the distance between the moving blocks. This allows the device to adapt to the stacking and cutting of pipes of different diameters. The fixed rod is threaded to the outer wall of the moving block, so the fixed rod and the parts fixed on it can be replaced together. This allows the rubber pads and springs of different diameters to be replaced when encountering pipes of different diameters. Through the application of the above components, the adaptability of the device is effectively improved and the cost is reduced. Attached Figure Description

The operator first adjusts the position of the slide table 15 and the fixed shell 111 according to the required cutting length, and fixes the slide table 15. The operator then checks whether the saw blade on the saw frame 14 is working properly, raises the saw frame 14, places the stainless steel pipe on the top of the machine base 13, pushes the stainless steel pipe to contact the moving blocks 311, and fixes the stainless steel pipe through the clamping platform on the top of the machine base 13. Then, the saw frame 14 is started, and the stainless steel pipe is cut when the saw frame 14 falls.

[0061] The regulating mechanism 1 also includes:

[0062] Locking assembly 11 is installed on the outer wall of the fixed housing 111;

[0063] Gear assembly 12 is mounted on the outer wall of the fixing block 211;

[0064] When the rotating shaft 112 drives the gear 121 to rotate, it will drive the gear assembly 12 to rotate. The locking assembly 11 can restrict the rotation of the rotating shaft 112.

[0065] The pitch mechanism 2 also includes:

[0070] Friction assembly 31 is installed on the outer wall of fixed rod 312;

[0071] Support component 32 is installed on the outer wall of fixed rod 312;

[0072] Among them, the support component 32 supports the friction component 31 to be in close contact with the inner wall of the steel pipe.

[0073] Example 2, please refer to Figures 4-9 The present invention is a cutting machine for the production of stainless steel products. Based on the first embodiment, the locking assembly 11 includes a plurality of locking blocks 113 rotatably connected to the outer wall of the fixed shell 111, and the inner walls of the plurality of locking blocks 113 are all fixedly connected with torsion springs 114.

[0074] The side of the torsion spring 114 away from the locking block 113 is fixedly connected to the fixed shell 111;

[0075] There are two locking blocks 113, which are set in a mirror image. The torsion spring 114 has a certain elastic potential energy in its initial state, which drives the side of the locking block 113 away from the torsion spring 114 to be in close contact with the rotating shaft 112. The locking block 113 is made of wear-resistant metal.

[0076] Gear assembly 12 includes a second gear 122 rotatably connected to the outer wall of the fixed block 211;

[0077] Among them, gear 122 meshes with gear 121;

[0078] Two gears 122 are rotatably connected to the outer walls of the two fixed blocks 211 near the rotating shaft 112 on their adjacent sides. The two gears 122 mesh with the two gears 121 respectively.

[0079] The sliding component 21 includes a movable rod 213 that is fixedly connected to the outer wall of the fixed block 211;

[0080] Among them, the movable rod 213 connects two fixed blocks 211 that are arranged opposite to each other in a set;

[0081] Two sliding blocks 212 arranged opposite each other in a group are also fixedly connected to moving rods 213 on their adjacent sides. A total of six moving rods 213 are provided. The three moving rods 213 near the locking block 113 are perpendicular to the other three moving rods 213. The six moving rods 213 are divided into two groups, and the three moving rods 213 in one group are arranged in a linear array.

[0082] The linkage assembly 22 includes a drive rod 221 fixedly connected to the outer wall of the gear 2 122. A long connecting rod 222 is rotatably connected to the side of the drive rod 221 away from the gear 2 122, and a short connecting rod 223 is rotatably connected to the side of the long connecting rod 222 away from the drive rod 221.

[0083] Among them, the long connecting rod 222 is rotatably connected to the outer wall of the sliding block 212 near the fixed block 211, and the short connecting rod 223 is rotatably connected to the outer wall of the sliding block 212 away from the fixed block 211.

[0084] The length of the long connecting rod 222 is twice that of the drive rod 221 and the short connecting rod 223. The drive rod 221, the long connecting rod 222 and the short connecting rod 223 are all located on the side close to the rotating shaft 112.

[0085] After the pipes are stacked, adjust the position of the slide table 15 and the fixed shell 111 to the cutting length and fix them in place. Then press the two locking blocks 113, causing the torsion spring 114 to accumulate elastic potential energy. The side of the two locking blocks 113 away from the torsion spring 114 is not in contact with the rotating shaft 112. Rotate the rotating shaft 112, which drives the two gears 121 to rotate. At this time, the two gears 122 meshing with the gears 121 also rotate, thereby driving the drive rod 221 to rotate. At this time, the drive rod 221 pushes the long connecting rod 222 to move upward, and the long connecting rod 222 rotates, pushing the short connecting rod 223 to rotate and move upward, so that the sliding block 212 can move upward, and the two The spacing between the sliding blocks 212 and the fixed blocks 211 remains equal. Similarly, the sliding blocks 212 in the vertical direction and the sliding blocks 212 in the horizontal direction move the same distance, thereby driving the moving rod 213 to move. The moving blocks 311 slide on the moving rod 213. The moving blocks 311 can move at the same speed in the vertical and horizontal directions. The nine moving blocks 311 are always in a linear array. Adjust the spacing between the moving blocks 311 to be equal to the spacing between the stainless steel pipes, release the two locking blocks 113, and the torsion spring 114 releases its elastic potential energy, causing the locking blocks 113 to contact the rotating shaft 112. Through friction, the rotating shaft 112 remains fixed and does not rotate, and the position of the moving blocks 311 remains fixed.

[0086] Friction assembly 31 includes a rubber pad 313 fixedly connected to the outer wall of fixed rod 312;

[0087] Among them, the rubber pad 313 is made of hard rubber. When the rubber pad 313 is not in contact with the stainless steel pipe, it is conical, with the large diameter position close to the moving block 311.

[0088] The support assembly 32 includes several spring pieces 321 fixedly connected to the outer wall of the fixed rod 312, and a protective piece 322 is fixedly connected to the outer wall of the moving block 311.

[0089] Among them, the protective plate 322 is located at the small diameter end of the rubber pad 313;

[0090] There are four spring pieces 321 arranged in a circular array. The side of the spring piece 321 away from the fixing rod 312 is fixedly connected to the rubber pad 313. The rubber pad 313 is in a free state when it is not in contact with the stainless steel pipe.

[0091] The stainless steel pipe is pushed toward the fixed shell 111, so that the pipe contacts the rubber pad 313. During the continuous pushing process, the inner wall of the pipe presses the rubber pad 313 and causes the spring piece 321 to deform. The spring piece 321 accumulates elastic potential energy. After the pipe contacts the moving block 311, it reaches the designated position. Under the influence of its own elastic potential energy, the spring piece 321 applies strong pressure to the inner wall of the pipe and presses the rubber pad 313 tightly against the inner wall of the pipe, thereby restricting the axial movement of the pipe.

[0092] One specific application of this embodiment is as follows: When in use, the operator first adjusts the position of the slide table 15 and the fixed shell 111 according to the required cutting length, and fixes the slide table 15. Then, the operator checks whether the saw blade on the saw frame 14 can be used normally. The operator then raises the saw frame 14, places the stainless steel pipe on the top of the machine base 13, pushes the stainless steel pipe to contact the moving block 311, and fixes the stainless steel pipe through the clamping platform on the top of the machine base 13. Then, the operator starts the saw frame 14, and the stainless steel pipe is cut when the saw frame 14 falls.

[0093] To reduce the time wasted on single-pipe cutting and improve overall production efficiency, multi-pipe stacking and clamping methods are often used for centralized sawing. Since stainless steel pipes generally have thin walls, if the clamping load applied by the clamping mechanism is too large, the pipe wall will experience plastic indentation deformation that is difficult to recover from. Conversely, if the clamping pressure is set too low, the pipe is prone to axial movement during sawing. Pipes in the middle layer of the stacked structure have a higher risk of movement than those on the outer layers. Movement in these pipes will exert lateral loads on the high-speed saw blade, continuously interfering with the blade's trajectory and tension stability. This can cause the saw blade to detach, affecting production, or even break due to a sudden increase in lateral alternating stress, posing a safety risk. After the materials are stacked, adjust the position of the slide table 15 and the fixed shell 111 to the cutting length and fix them. Then press the two locking blocks 113 to allow the torsion spring 114 to accumulate elastic potential energy. The side of the two locking blocks 113 away from the torsion spring 114 does not contact the rotating shaft 112. Rotate the rotating shaft 112, which drives the two gears 121 to rotate. At this time, the two gears 122 meshing with the gears 121 also rotate, thereby driving the rod 221 to rotate. At this time, the driving rod 221 pushes the long connecting rod 222 to move upward, and the long connecting rod 222 rotates, pushing the short connecting rod 223 to rotate and move upward. Thus, the sliding block 212 can move upward, and the two sliding blocks 212... The spacing between the fixed blocks 211 remains constant. Similarly, the sliding blocks 212 in the vertical direction and the sliding blocks 212 in the horizontal direction move the same distance, thereby causing the moving rod 213 to move. The moving blocks 311 slide on the moving rod 213. The moving blocks 311 can move at the same speed in the vertical and horizontal directions. The nine moving blocks 311 are always in a linear array. Adjust the spacing between the moving blocks 311 to be equal to the spacing between the stainless steel tubes, release the two locking blocks 113, and the torsion spring 114 releases its elastic potential energy, causing the locking blocks 113 to contact the rotating shaft 112. Through friction, the rotating shaft 112 remains fixed and does not rotate. The position of the moving blocks 311 remains fixed. At this time, the stainless steel tube is moved towards the fixed shell. The pipe is advanced in the 111 direction, causing it to contact the rubber pad 313. During the continuous advancement, the inner wall of the pipe presses against the rubber pad 313, causing the spring 321 to deform. The spring 321 accumulates elastic potential energy. After the pipe contacts the moving block 311 and reaches the designated position, the spring 321, under the influence of its own elastic potential energy, applies strong pressure to the inner wall of the pipe and presses the rubber pad 313 tightly against the inner wall of the pipe, thereby restricting the axial movement of the pipe. Through the application of the above components, the problem of insufficient clamping force when cutting stacked stainless steel pipes, which leads to the movement of the stainless steel pipes during the cutting process, the lateral load on the saw blade, and the saw blade falling off or even breaking is effectively alleviated.

[0094] Utilizing the characteristic of the aforementioned device where the spring 321 compresses the rubber pad 313 tightly against the pipe, the periodic impact force generated by the saw blade during cutting will act on the pipe. If the cutting length is too long, the protruding part of the pipe is prone to vibration during the cutting process, resulting in continuous compression of the saw blade at the cutting position. The saw blade is repeatedly clamped and released, reducing its lifespan. Furthermore, when the cutting is about to be completed, a portion of the pipe remains uncut. The repeated vibration acts on the uncut portion, causing the remaining small part of the pipe to tear rather than be cut, resulting in large burrs on the pipe. Moreover, when the pipe breaks, the stress is suddenly released, causing the pipe to jump and collide with the remaining uncut sections, exacerbating the burr problem. When the spring 321 compresses the rubber pad 313 tightly against the inner wall of the pipe... At this point, fixing the pipe reduces the pipe axis movement. Fixing the pipe end reduces the vibration of the pipe during cutting. The spring 321 can still undergo slight deformation, which can absorb the high-frequency fine vibration generated by cutting. This alleviates the problem of resonance during cutting when the pipe is fully fixed, which causes vibration marks on the cutting surface. After the pipe is cut, the stress released by the pipe is transmitted to the rubber pad 313 and the spring 321 to absorb the released stress and reduce the jumping amplitude of the pipe. Through the application of the above components, the vibration of the protruding end during pipe cutting is effectively alleviated, which causes the pipe to repeatedly clamp and release the saw blade, resulting in saw blade damage and burrs on the pipe. At the same time, it alleviates the problem of sudden stress release when the pipe is broken, which causes the pipe to jump and collide with other pipes.

[0095] Utilizing the characteristics of the rubber pad 313 in contact with the pipe in the aforementioned equipment, burrs will exist on the surface of the pipe after cutting. When the burr side contacts the rubber pad 313, it will tear and scratch the rubber pad 313, causing damage and greatly reducing its service life. By setting a protective plate 322, when the pipe approaches the rubber pad 313, it will first contact the protective plate 322. At this time, after squeezing the protective plate 322, the protective plate 322 will first squeeze the rubber pad 313, reducing the taper of the rubber pad 313, thereby reducing the contact area between the rubber pad 313 and the pipe. When the pipe passes the rubber pad 313, the pipe has just pressed the spring 321, so that the rubber pad 313 has shrunk to the size of the inner diameter of the pipe. Through the application of the above components, the problem of burrs on the pipe cutting surface scratching the rubber pad 313 during the next cut, thus reducing the service life of the rubber pad 313, is effectively alleviated.

[0096] Utilizing the rotating shaft 112 of the aforementioned device, the distance between the fixed block 211 and the sliding block 212 can be adjusted when the shaft 112 is rotated. This changes the distance between the moving rod 213, thereby causing the moving block 311 to change its position in both the vertical and horizontal directions. The change in the distance between the moving blocks 311 allows for the stacking and cutting of pipes of different diameters. Furthermore, the fixed rod 312 is threaded onto the outer wall of the moving block 311, allowing the fixed rod 312 and the parts fixed to it to be replaced together. This enables the replacement of rubber pads 313 and spring sheets 321 of corresponding diameters when encountering pipes of different diameters. Through the application of the above components, the adaptability of the device is effectively improved, and the cost is reduced.
