Description

Technical Field

[0001] The invention relates to the field of cutting equipment, in particular to automatic cutting equipment for stainless steel pipes. Background Art

[0002] As an indispensable basic material in modern industry, stainless steel pipes are widely used in the petrochemical, aerospace, automotive, food processing, architectural decoration and other fields due to their corrosion resistance, high strength, and high temperature resistance. Amid the rapid development of the intelligent manufacturing equipment industry, the production and processing of stainless steel pipes are gradually upgrading towards automation, precision, and flexibility. Metal cutting technology, especially cutting, is the core link in ensuring its quality and efficiency.

[0003] In the prior art, stainless steel pipes are generally cut by a rotating circular cutting knife. During use and observation, it is found that the cut stainless steel pipes usually fall directly onto the surface of the chute for transportation, which will cause the stainless steel pipes to be subjected to the impact force generated by free fall, thereby causing damage to the surface of the stainless steel pipes.

[0004] Therefore, in response to the above problems, a stainless steel pipe automatic cutting device is proposed. Summary of the Invention

[0005] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0006] The technical solution adopted by the present invention to solve its technical problem is: the automatic cutting equipment for stainless steel pipes described in the present invention includes a frame, the top of the frame is fixedly connected to a mounting plate; the top of the mounting plate is fixedly connected to a first cylinder; the output end of the first cylinder is fixedly connected to a support plate; a cutting assembly for cutting steel pipes is fixedly installed at the bottom of the support plate; a pair of support assemblies for lifting the cut section of the steel pipe are provided at the bottom of the support plate; a clamping assembly for fixing the steel pipe during cutting is provided at the top of the frame; the support assembly includes a first rack; the first rack is fixedly connected to the bottom of the support plate; the top of the frame is provided There is a groove that slides with the first rack, a gear is rotatably connected in the groove, and a second rack is slidably connected in the groove; the gear is in meshing relationship with the first rack and the second rack; a connecting plate is fixed to one side of the second rack, and a plurality of push rods are fixed to the bottom of the connecting plate, and the push rods are arranged in an arc shape; a chute is provided on the top of the frame, and a cavity is provided on the chute for placing the connecting plate and the push rod; through the cooperation of the connecting plate and the push rod, the cut section of the steel pipe can be lifted under the meshing action of the first rack, the gear and the second rack, so that it falls stably on the chute, reducing the damage caused by impact when the steel pipe falls directly.

[0007] Preferably, a sponge is fixed to the surface of the push rod; an exhaust pipe is connected to the top of the connecting plate; the connecting plate and multiple push rods are connected; the push rod and the sponge surface are porous; by arranging the sponge, the sponge can adapt to the gap existing when the push rod contacts the steel pipe, thereby allowing the push rod to adsorb the steel pipe, thereby improving the stability of the push rod when lifting the steel pipe.

[0008] Preferably, an air cavity is fixedly connected to the inner wall of the circular hole on the surface of the push rod; the surface of the air cavity is porous; a blocking block is slidably connected to the inner wall of the air cavity; a spring is fixedly connected between the blocking block and the inner wall of the air cavity; a trigger rod is fixedly connected to the other end of the blocking block; when there are differences in the sizes of the steel pipes, the smaller steel pipe will find it difficult to fully contact the push rod. At this time, the trigger rod corresponding to the sponge surface that the steel pipe can contact will slide into the interior of the air cavity with the blocking block under the squeezing action of the steel pipe, and put the spring in a compressed state. At this time, the air cavity can be connected to the outside world, so that the steel pipe can be opened. The holes of the push rod that are in contact with the pipe are in a negative pressure state, and the other blockages that are not in contact with the holes can still maintain a closed state to the air cavity under the elastic force of the spring. Since the total air pressure in the push rod is constant, the flow velocity in the holes that are in contact with the steel pipe can be increased, thereby improving the adsorption effect on the steel pipe. In addition, when the vacuum pump stops working, the assembly consisting of the trigger rod and the block can support the steel pipe under the action of the spring to reduce the adhesion between the steel pipe and the push rod caused by adsorption. Finally, the end of the trigger rod can be spherical to reduce the friction resistance caused by contact between the trigger rod and the steel pipe.

[0009] Preferably, a V-shaped groove is provided on the inner wall of the chute; the V-shaped groove is located between a pair of supporting components; guide wheels are symmetrically installed on the inner wall of the chute; a pair of fixing rods are fixedly connected to one side of the frame, and a fixing plate is fixedly connected between the ends of the pair of fixing rods; after the steel pipe is released from the top rod and falls into the inside of the chute, the steel pipe can enter the inside of the V-shaped groove and slide to the top of the fixing rod under the guidance of the shape of the V-shaped groove. A pair of fixing rods can respectively suspend the steel pipe from the bottom, and the fixing plate will limit the steel pipe, so that the subsequently cut steel pipe will be temporarily stacked above the fixing rod for subsequent staff to take the material. In addition, there is a small distance between the guide wheel and the edge of the V-shaped groove to ensure that the steel pipe in the V-shaped groove will not slip out.

[0010] Preferably, a slide groove is provided on the surface of the fixed plate, a cross plate is rotatably connected in the slide groove, and a card plate is slidably connected in the slide groove; a handle is fixed on the top of the card plate, and the handle and the fixed plate are through-set and slidably connected; a support rod is provided between the cross plate and the card plate; when the steel pipe falls above the fixed rod, it will pass through the support rod and be stacked on the top of the fixed plate one after another, and it can be seen at this time Figure 7The pallet limits the upper part of the cross plate, and the support rod limits the lower part of the cross plate. When the steel pipe needs to be taken out, the staff can lift the handle of the pallet to release the limiting effect of the pallet on the cross plate. Then they can hold one end of the support rod and slide it along the slide groove on the surface of the fixed plate, so that the support rod can pass through the cross plate and rotate the cross plate 90° counterclockwise to achieve the removal of the support rod. At this time, the steel pipes connected in series on its surface can be transferred in batches through the support rod. When installing, the support rod can enter the slide groove and squeeze the cross plate. The cross plate can be rotated 90° clockwise under the squeezing action of the support rod. When the left end of the cross plate rotates, it can squeeze the pallet and lift it until the support rod enters between the pallet and the cross plate, thereby achieving rapid installation of the support rod.

[0011] Preferably, a plurality of first heart-shaped plates are fixedly connected to the middle part of the support rod; the first heart-shaped plates are arranged at equal distances; by setting the first heart-shaped plates, the steel pipe is in an eccentric state with the support rod when it initially slides on the fixed rod, so the first heart-shaped plates do not contact the steel pipe, and when the support rod is removed from the fixed plate, the steel pipe can be in a concentric state with the support rod, and at this time, the two ends of the surface of the first heart-shaped plate can be in line contact with the steel pipe, so that the steel pipe can be subjected to more friction when being transported by the support rod, thereby improving the stability of the steel pipe during transportation.

[0012] Preferably, the end of the support rod is fixed with a positioning plate; one side of the fixing plate is fixed with a positioning groove; the positioning groove and the positioning plate are arranged in a corresponding shape; through the cooperation of the positioning groove and the positioning plate, when the support rod is installed, the positioning plate and the inner wall shape of the positioning groove can be aligned, so that when the support rod is installed between the cross plate and the clamping plate, the positioning plate can also be matched with the positioning groove to achieve fixation and positioning of the support rod, thereby ensuring that the first heart-shaped plate can be in the upper position and will not cause obstruction when the steel pipe is discharged.

[0013] Preferably, the end of the support rod is threadedly connected to a baffle; the size of the baffle is larger than that of the first heart-shaped plate; the baffle is initially the same as the first heart-shaped plate and does not come into contact with the steel pipe. Before removing the support rod from the fixed plate, the baffle can be rotated to be screwed into the interior of the support rod under the action of thread transmission. The rotation can be half a circle or additional several weeks, so that the baffle can be rotated to the bottom and contact and limit the steel pipe near the end, further improving the stability of the steel pipe when being transported by the support rod. In addition, even if the baffle does not come into contact with the steel pipe, it can still limit the steel pipe on the support rod to reduce the situation where the steel pipe falls off the support rod.

[0014] Preferably, the clamping assembly includes a vertical plate; the vertical plate is fixedly mounted on the top of the frame; a second cylinder is fixedly connected to one side of the vertical plate; a circular plate is rotatably connected to the inner wall of the vertical plate; the top of the circular plate is rotatably connected to the output end of the second cylinder; a plurality of wavy grooves are provided on the surface of the circular plate, and grooves are provided at corresponding positions on the surface of the vertical plate; a pressure block is slidably connected in the wavy groove of the circular plate, and the pressure block and the groove on the surface of the vertical plate are both slidably connected; when the steel pipe needs to be fixed, the second cylinder can be started to drive the circular plate to rotate, and when the circular plate rotates, the plurality of pressure blocks can be driven to approach the outer wall of the steel pipe at the same time under the cooperation of the wavy groove on its surface and the groove on the surface of the vertical plate, so as to clamp the steel pipe and realize rapid fixation of the steel pipe.

[0015] Preferably, a pair of partitions are fixed to the top of the frame; the partitions are located on one side of the first rack; by setting the partitions, the partitions can block the groove where the first rack is located to reduce the contamination caused by splashing debris when it is cut by the steel pipe, thereby affecting the stable engagement between the first rack, the gear, and the second rack.

[0016] The present invention is beneficial in that: 1.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Specific examples are given below.

[0023] See also Figures 1 to 8 As shown, an automatic stainless steel pipe cutting device according to an embodiment of the present invention includes a frame 1, a mounting plate 12 is fixedly connected to the top of the frame 1; a first cylinder 13 is fixedly connected to the top of the mounting plate 12; a support plate 14 is fixedly connected to the output end of the first cylinder 13; a cutting assembly for cutting steel pipes is fixedly installed at the bottom of the support plate 14; a pair of support assemblies for lifting the cut section of the steel pipe are provided at the bottom of the support plate 14; a clamping assembly for fixing the steel pipe during cutting is provided at the top of the frame 1; the support assembly includes a first rack 15; the first rack 15 is fixedly connected to the bottom of the support plate 14; a groove is provided on the top of the frame 1 for sliding cooperation with the first rack 15, a gear 16 is rotatably connected in the groove, and a second rack 17 is slidably connected in the groove; the gear 16 is in meshing relationship with the first rack 15 and the second rack 17; a connecting plate 18 is fixedly connected to one side of the second rack 17, and a plurality of ejector rods 19 are fixedly connected to the bottom of the connecting plate 18, and the ejector rods 19 are arranged in an arc shape; a chute 110 is provided on the top of the frame 1, and a cavity is provided on the chute 110 for placing the connecting plate 18 and the ejector rods 19; The steel pipe is conveyed to the bottom of the mounting plate 12. The steel pipe conveying method can be intermittent conveying by a V-shaped conveying roller. After controlling the cutting length of the steel pipe, the steel pipe can be fixed by the clamping assembly. Then the first cylinder 13 can be started to push the support plate 14, so that the support plate 14 brings the cutting assembly close to the steel pipe. The cutting assembly can cut the steel pipe by a rotating tool. During the movement of the support plate 14, it can move synchronously with the first rack 15. The first rack 15 will mesh with the gear 16. The gear 16 can mesh with the second rack 17 to transmit the power of the first rack 15 to the second rack 17, so that the second rack 17 can move vertically in the opposite direction of the first rack 15. The second rack 17 can move together with the connecting plate 18 and the top rod 19 and approach the steel pipe cutting section. The steel pipe is cut by the cutting assembly During cutting, the cut section can be supported by the push rods 19 on both sides so as not to fall suddenly onto the chute 110. After cutting, the first cylinder 13 can be started and reset. When the support plate 14 is reset, the first rack 15 can be engaged with the gear 16, and the gear 16 can be engaged with the second rack 17 to reset the second rack 17. The second rack 17 can be lowered with the cut steel pipe through the connecting plate 18 and the push rod 19. During the process, the steel pipe can be separated from the push rod 19 when it contacts the chute 110 and slide out under the action of gravity, and the steel pipe can be collected by the box body; through the cooperation of the connecting plate 18 and the push rod 19, the cut section of the steel pipe can be lifted under the meshing action of the first rack 15, the gear 16, and the second rack 17, so that it can fall stably onto the chute 110, reducing the damage caused by impact when the steel pipe falls directly.

[0024] See also Figure 4 and Figure 5 As shown, the surface of the ejector pin 19 is fixed with a sponge 2; the top of the connecting plate 18 is connected to an exhaust pipe 22; the connecting plate 18 and the plurality of ejector pins 19 are in communication; the ejector pins 19 and the surface of the sponge 2 are porous; When the cut steel pipe is lifted, the negative pressure supply device connected to the end of the exhaust pipe 22 will be started. The negative pressure supply device can be specifically a vacuum pump. After starting, the connecting plate 18 and the push rod 19 will be in a negative pressure state, and the steel pipe will also come into contact with the sponge 2 when it falls to the surface of the push rod 19. Because of its flexibility, the sponge 2 can be concave and adhered to the surface of the steel pipe under the action of the squeezing, so that the steel pipe can be adsorbed to the surface of the push rod 19 under the adhesion action of the sponge 2 and the negative pressure of the circular holes on the surface of the push rod 19, so as to improve the stability of the steel pipe when being lifted on the push rod 19. In addition, when the steel pipe falls to a certain distance as the push rod 19 is about to contact the chute 110, the vacuum pump can stop working to ensure that the steel pipe can be stably removed from the push rod 19; by providing the sponge 2, the sponge 2 can adapt to the gap existing when the push rod 19 contacts the steel pipe, thereby allowing the push rod 19 to adsorb the steel pipe, thereby improving the stability of the push rod 19 when lifting the steel pipe.

[0025] See also Figure 5 As shown, the inner wall of the circular hole on the surface of the push rod 19 is fixedly connected to the air cavity 3; the surface of the air cavity 3 is porous; the inner wall of the air cavity 3 is slidably connected to a blocking block 32; a spring is fixedly connected between the blocking block 32 and the inner wall of the air cavity 3; the other end of the blocking block 32 is fixedly connected to a trigger rod 33; When there are differences in the sizes of the steel pipes, the smaller steel pipe will find it difficult to fully contact the push rod 19. At this time, the trigger rod 33 corresponding to the surface of the sponge 2 that the steel pipe can contact will slide into the interior of the air cavity 3 with the block 32 under the squeezing action of the steel pipe, and put the spring in a compressed state. At this time, the air cavity 3 can be connected to the outside world, so that the hole of the push rod 19 that the steel pipe contacts is in a negative pressure state, and the remaining block 32 that does not contact the hole can still maintain a closed state to the air cavity 3 under the elastic force of the spring. Since the total air pressure in the push rod 19 is constant, the flow rate at the hole that the steel pipe contacts can be increased, thereby improving the adsorption effect on the steel pipe. In addition, when the vacuum pump stops working, the assembly composed of the trigger rod 33 and the block 32 can support the steel pipe under the action of the spring to reduce the adhesion between the steel pipe and the push rod 19 caused by adsorption. Finally, the end of the trigger rod 33 can be spherical to reduce the friction resistance caused by contact between the trigger rod 33 and the steel pipe.

[0026] See also Figure 1 and Figure 6 As shown, a V-shaped groove 4 is formed on the inner wall of the chute 110; the V-shaped groove 4 is located between a pair of support assemblies; guide wheels 42 are symmetrically mounted on the inner wall of the chute 110; a pair of fixing rods 43 are fixed to one side of the frame 1, and a fixing plate 44 is fixed between the ends of the pair of fixing rods 43; After the steel pipe comes off the top rod 19 and falls into the chute 110, the steel pipe can enter the interior of the V-shaped groove 4 and slide to the top of the fixed rod 43 under the guidance of the shape of the V-shaped groove 4. A pair of fixed rods 43 can respectively suspend the steel pipe from the bottom, and the fixed plate 44 will limit the steel pipe so that the subsequently cut steel pipe will be temporarily stacked above the fixed rod 43 for subsequent staff to take the material. In addition, there is a small distance between the guide wheel 42 and the edge of the V-shaped groove 4 to ensure that the steel pipe in the V-shaped groove 4 will not slip out.

[0027] See also Figure 6 and Figure 7 As shown, a sliding groove is provided on the surface of the fixed plate 44, in which a cross plate 52 is rotatably connected, and a clamping plate 53 is slidably connected in the sliding groove; a handle is fixed to the top of the clamping plate 53, and the handle and the fixed plate 44 are provided through and slidably connected; a support rod 5 is provided between the cross plate 52 and the clamping plate 53; When the steel pipe falls onto the fixing rod 43, it will pass through the support rod 5 and gradually stack onto the fixing plate 44. Figure 7When the left end of the cross plate 52 rotates, the card plate 53 can be squeezed and lifted up until the support rod 5 enters between the card plate 53 and the cross plate 52, thereby realizing the rapid installation of the support rod 5.

[0028] See also Figure 6 As shown, a plurality of first heart-shaped plates 6 are fixedly connected to the middle of the support rod 5; the first heart-shaped plates 6 are arranged at equal distances; By setting the first heart-shaped plate 6, the steel pipe is initially in an eccentric state with the strut 5 when sliding on the fixed rod 43, so the first heart-shaped plate 6 does not contact the steel pipe. When the strut 5 is removed from the fixed plate 44, the steel pipe can be concentric with the strut 5. At this time, the two ends of the surface of the first heart-shaped plate 6 can be in line contact with the steel pipe, so that the steel pipe can be subjected to more friction when being transported by the strut 5, thereby improving the stability of the steel pipe during transportation.

[0029] See also Figure 6 and Figure 7 As shown, the end of the support rod 5 is fixed with a positioning plate 72; one side of the fixing plate 44 is fixed with a positioning groove 7; the positioning groove 7 and the positioning plate 72 are arranged in a corresponding shape; Through the cooperation between the positioning groove 7 and the positioning plate 72, when the strut 5 is installed, the positioning plate 72 can be aligned with the inner wall shape of the positioning groove 7 so that when the strut 5 is installed between the cross plate 52 and the clamping plate 53, the positioning plate 72 can also be fitted and docked with the positioning groove 7 to achieve the fixation and positioning of the strut 5, thereby ensuring that the first heart-shaped plate 6 can be in the upper position and will not cause any obstruction to the discharge of the steel pipe.

[0030] See also Figure 6 As shown, the end of the support rod 5 is threadedly connected to a baffle 8; the size of the baffle 8 is larger than that of the first heart-shaped plate 6; The baffle 8 is initially the same as the first heart-shaped plate 6 and does not come into contact with the steel pipe. Before removing the strut 5 from the fixed plate 44, the baffle 8 can be rotated to screw into the interior of the strut 5 under the action of threaded transmission. The rotation can be half a circle or several additional circles, so that the baffle 8 can be rotated to the bottom and contact and limit the steel pipe near the end, further improving the stability of the steel pipe when being transported by the strut 5. In addition, even if the baffle 8 does not come into contact with the steel pipe, it can still limit the steel pipe on the strut 5 to reduce the situation where the steel pipe falls off the strut 5.

[0031] See also Figure 8 As shown, the clamping assembly includes a vertical plate 9; the vertical plate 9 is fixedly mounted on the top of the frame 1; a second cylinder 92 is fixedly connected to one side of the vertical plate 9; a circular plate 93 is rotatably connected to the inner wall of the vertical plate 9; the top of the circular plate 93 is rotatably connected to the output end of the second cylinder 92; a plurality of wavy grooves are provided on the surface of the circular plate 93, and corresponding grooves are provided on the surface of the vertical plate 9; a pressure block 94 is slidably connected in the wavy groove of the circular plate 93, and the pressure block 94 is slidably connected to the groove on the surface of the vertical plate 9; When the steel pipe needs to be fixed, the second cylinder 92 can be started to drive the circular plate 93 to rotate. When the circular plate 93 rotates, the wavy groove on its surface and the groove on the surface of the vertical plate 9 can cooperate to drive multiple pressure blocks 94 to approach the outer wall of the steel pipe at the same time to clamp the steel pipe and achieve rapid fixation of the steel pipe.

[0032] See also Figure 1 As shown, a pair of partitions 10 are fixed to the top of the frame 1; the partitions 10 are located on one side of the first rack 15; By setting up the partition 10, the partition 10 can block the groove where the first rack 15 is located to reduce the pollution caused by splashing debris when it is cut by the steel pipe, thereby affecting the stable engagement between the first rack 15, the gear 16, and the second rack 17.

[0033] Working principle: The steel pipe is conveyed to the bottom of the mounting plate 12. The steel pipe conveying method can be intermittent conveying by a V-shaped conveyor roller. After controlling the cutting length of the steel pipe, the steel pipe can be fixed by the clamping assembly. Then the first cylinder 13 can be started to push the support plate 14, so that the support plate 14 brings the cutting assembly closer to the steel pipe. The cutting assembly can cut the steel pipe through a rotating tool. During the movement of the support plate 14, it can move synchronously with the first rack 15, and the first rack 15 will engage with the gear 16. The gear 16 can engage with the second rack 17 to transmit the power of the first rack 15 to the second rack 17, so that the second rack 17 can move vertically in the opposite direction of the first rack 15, and the second rack 17 can move together with the connecting plate 18 and the top rod 19 And approach the cutting section of the steel pipe. When the steel pipe is cut by the cutting assembly, its cutting section can be supported by the push rods 19 on both sides so as not to fall suddenly onto the chute 110. After cutting, the first cylinder 13 can be started and reset. When the support plate 14 is reset, the first rack 15 can be engaged with the gear 16, and the gear 16 can be engaged with the second rack 17 to reset the second rack 17. The second rack 17 can be lowered with the cut steel pipe through the connecting plate 18 and the push rod 19. During the process, the steel pipe can be separated from the push rod 19 when it contacts the chute 110 and slide out under the action of gravity. The steel pipe can be collected by the box body; when the cut steel pipe is lifted, the negative pressure supply device connected to the end of the exhaust pipe 22 will be started. The negative pressure supply device can be specifically a vacuum pump. After starting The connecting plate 18 and the push rod 19 can be in a negative pressure state, and when the steel pipe falls to the surface of the push rod 19, it will also come into contact with the sponge 2. Due to its flexibility, the sponge 2 can be concave and adhered to the surface of the steel pipe under the action of squeezing, so that the steel pipe can be adsorbed to the surface of the push rod 19 under the action of the adhesion of the sponge 2 and the negative pressure of the circular holes on the surface of the push rod 19, so as to improve the stability of the steel pipe when it is lifted on the push rod 19. In addition, when the steel pipe is lowered to a certain distance with the push rod 19, that is, when the steel pipe is about to come into contact with the chute 110, the vacuum pump can stop working to ensure that the steel pipe can be stably removed from the push rod 19; when there are differences in the sizes of the steel pipes, the smaller steel pipe will find it difficult to fully contact the push rod 19. At this time, the trigger rod 33 corresponding to the surface of the sponge 2 that the steel pipe can contact will be on the steel Under the extrusion of the tube, the block 32 slides into the interior of the air cavity 3 and puts the spring in a compressed state. At this time, the air cavity 3 can be connected to the outside world, so that the hole of the push rod 19 that contacts the steel tube is in a negative pressure state. The remaining block 32 that does not contact the hole can still maintain a closed state to the air cavity 3 under the elastic force of the spring. Since the total air pressure in the push rod 19 is constant, the flow rate at the hole that contacts the steel tube can be increased, thereby improving the adsorption effect on the steel tube. In addition, when the vacuum pump stops working, the assembly composed of the trigger rod 33 and the block 32 can support the steel tube under the action of the spring to reduce the adhesion between the steel tube and the push rod 19 caused by adsorption. Finally, the end of the trigger rod 33 can be spherical to reduce the friction resistance caused by contact between the trigger rod 33 and the steel tube.After the steel pipe is released from the top rod 19 and falls into the chute 110, the steel pipe can enter the interior of the V-shaped groove 4 and slide to the top of the fixing rod 43 under the guidance of the shape of the V-shaped groove 4. A pair of fixing rods 43 can respectively suspend the steel pipe from the bottom, and the fixing plate 44 will limit the steel pipe so that the subsequently cut steel pipes will be temporarily stacked above the fixing rod 43 for subsequent staff to take the material. In addition, there is a small distance between the guide wheel 42 and the edge of the V-shaped groove 4 to ensure that the steel pipe in the V-shaped groove 4 will not slide out; when the steel pipe falls above the fixing rod 43, it will pass through the support rod 5 and be stacked on the fixing plate 44 one after another. At this time, it can be seen; Figure 7The clamping plate 53 limits the upper part of the cross plate 52, and the support rod 5 limits the lower part of the cross plate 52. When the steel pipe needs to be taken out, the staff can lift the handle of the clamping plate 53 to release the limiting effect of the clamping plate 53 on the cross plate 52. Then, one end of the support rod 5 can be held and slid along the sliding groove on the surface of the fixed plate 44, so that the support rod 5 can pass through the cross plate 52 and rotate the cross plate 52 90 degrees counterclockwise to realize the removal of the support rod 5. At this time, the steel pipes connected in series on its surface can be transported in batches through the support rod 5. When installing, the support rod 5 can enter the sliding groove and squeeze the cross plate 52. The cross plate 52 can be rotated 90 degrees clockwise under the squeezing action of the support rod 5. When the left end thereof rotates, the clamping plate 53 can be squeezed and lifted until the strut 5 enters between the clamping plate 53 and the cross plate 52, thereby realizing the rapid installation of the strut 5. By providing the first heart-shaped plate 6, the steel pipe is initially eccentric with the strut 5 when sliding on the fixing rod 43, so the first heart-shaped plate 6 and the steel pipe do not contact each other. When the strut 5 is removed from the fixing plate 44, the steel pipe can be concentric with the strut 5. At this time, the two ends of the surface of the first heart-shaped plate 6 can be in line contact with the steel pipe, so that the steel pipe can be subjected to more friction when being transported by the strut 5, thereby improving the stability of the steel pipe during transportation. Through the cooperation of the positioning groove 7 and the positioning plate 72, when the strut 5 is installed, the positioning plate 72 can be aligned with the steel pipe. The shape of 72 and the inner wall of the positioning groove 7 makes it possible for the positioning plate 72 to fit in with the positioning groove 7 when the support rod 5 is installed between the cross plate 52 and the clamping plate 53, so as to fix and position the support rod 5, thereby ensuring that the first heart-shaped plate 6 can be in the upper position and will not cause any obstruction when the steel pipe is discharged; the baffle 8 is initially the same as the first heart-shaped plate 6 and will not come into contact with the steel pipe. Before the support rod 5 is removed from the fixing plate 44, the baffle 8 can be rotated to make it screwed into the interior of the support rod 5 under the action of the threaded transmission. The rotation can be half a circle or additional weeks, so that the baffle 8 can be rotated downward and contact the steel pipe near the end to limit the position, further improving the stability of the steel pipe when it is transported by the support rod 5. In addition, the baffle Even if the plate 8 does not contact the steel pipe, it can still limit the steel pipe on the support rod 5 to reduce the situation where the steel pipe falls off the support rod 5; when the steel pipe needs to be fixed, the second cylinder 92 can be started to drive the circular plate 93 to rotate. When the circular plate 93 rotates, the wavy groove on its surface and the groove on the surface of the vertical plate 9 can cooperate to drive multiple pressure blocks 94 to approach the outer wall of the steel pipe at the same time to clamp the steel pipe and achieve rapid fixation of the steel pipe; by setting the partition 10, the partition 10 can block the groove where the first rack 15 is located to reduce the situation where it is contaminated by splashing debris when it is cut by the steel pipe, thereby affecting the stable engagement between the first rack 15, the gear 16, and the second rack 17.
