Description

Technical Field

[0001] This application relates to the field of bar conveying equipment, and in particular to a bar conveying device. Background Technology

[0002] A bar conveyor is a device used to transport bar-shaped materials (such as metal bars, pipes, timber, etc.) from one location to another. It utilizes conveyors, lifting devices, and clamping systems to transport, lift, and secure the bars, meeting the transportation needs of production lines or workplaces. Bar conveyors are commonly used in industrial production processes to improve production efficiency, reduce manpower input, and ensure the safety and stability of the bars during transportation.

[0003] In the aluminum profile extrusion molding process, aluminum bars need to be conveyed and pushed into the extrusion equipment. The existing technology usually places the bars in a steel structure trough and applies a thrust to the tail of the bars to push them into the extrusion equipment.

[0004] Regarding the aforementioned technologies, during the transport of bar stock, pressure needs to be applied directly to drive the bar stock to move. However, excessive or uneven pressure may cause the bar stock to bend, deform, or break, seriously affecting the integrity of the bar stock. Summary of the Invention

[0005] In order to improve the phenomenon that the bar stock is easily bent and deformed by directly applying pressure to the bar stock during the transportation process, this application provides a bar stock transportation device.

[0006] This application provides a bar stock conveying device, which adopts the following technical solution: A bar stock conveying device includes a bar stock conveying platform with an arc-shaped groove on its upper surface for placing bar stock; a bar stock conveying table with a bar stock conveying block on its upper surface for transporting bar stock to an extrusion device; and a connecting table with an inclined upper surface for the bar stock to slide into the bar stock conveying table. The bar stock conveying platform includes a base plate and a fixed plate. The fixed plate is vertically disposed on the upper surface of the base plate and is located at one end of the base plate. A connecting plate is provided between the fixed plate and the connecting table, located at the top of the fixed plate. The arc-shaped groove is formed on the upper surface of the connecting plate. The connecting plate has three abutment holes, all extending along the length of the connecting plate. A movable section is formed on the upper surface of the base plate. The connecting plate has a sliding block slidably connected to the sliding groove. A push cylinder is provided on the side of the fixed plate. The piston rod of the push cylinder passes through the fixed plate and is fixedly connected to the sliding block. The sliding block is slidably connected to the sliding groove of the base plate. The top of the sliding block is provided with three support plates for supporting the bar stock. The top of the three support plates matches the arc groove of the connecting plate. The support plates are slidably connected to the abutment holes of the connecting plate. The upper end of the sliding block is provided with two lifting cylinders. The end of the lifting cylinder away from the sliding block is provided with a support plate. The bottom ends of the three support plates are fixedly connected to the support plate. The connecting platform has three movable grooves at the end near the bar stock conveying platform. The three movable grooves are respectively connected to the arc groove of the connecting plate.

[0007] By adopting the above technical solution, when workers need to transfer and push the bar stock into the extrusion equipment, they first place the bar stock in the arc-shaped groove of the bar stock conveying table, and then activate the lifting cylinder. The piston rod of the lifting cylinder drives the support plate to rise, which in turn drives the three support plates to rise, making the height of the bar stock higher than the height of the worktable, thus achieving the lifting of the bar stock. Then, the workers activate the pushing cylinder, which drives the sliding block to move, so that the bar stock is above the connecting table. Then, the lifting cylinder is activated again, causing the support plates to retract into the device, and then the bar stock falls off the support plates, slides on the inclined surface of the worktable, and then enters the bar stock conveying block of the bar stock conveying table. Then, the bar stock is transported to the designated position by the conveying block. No pressure is directly applied to the bar stock throughout the process, avoiding the bending, deformation or breakage of the bar stock caused by pressure during transportation, which helps to improve the integrity of the bar stock during transportation.

[0008] Optionally, the top of the bar conveying block is provided with a fixing groove for placing the bar. The fixing groove extends along the length of the bar conveying block. A conveying cylinder is provided inside the connecting platform. The piston rod of the conveying cylinder is fixedly connected to the end of the bar conveying block near the connecting platform. The piston rod of the conveying cylinder is perpendicular to the end of the bar conveying block near the connecting platform. The bar conveying block is slidably connected to the upper surface of the bar conveying platform.

[0009] By adopting the above technical solution, when bar stock needs to be transported using a bar stock conveyor block, the bar stock slides from the connecting platform into the fixed groove of the bar stock conveyor block. Then, the operator starts the conveying cylinder, and the piston rod of the conveying cylinder drives the bar stock conveyor block to move, thereby transporting the bar stock to the designated position. This method is easy to understand and implement, and helps to improve work efficiency.

[0010] Optionally, the upper end face of the bar conveying platform is provided with two sliding grooves, both of which extend along the length of the bar conveying platform. The lower end face of the bar conveying block is provided with two sliding blocks, which are located at the sliding grooves of the bar conveying platform.

[0011] By adopting the above technical solution, during the sliding process of the bar conveyor, the sliding blocks will slide at the sliding groove of the bar conveyor, thereby restricting the movement direction of the bar conveyor blocks and improving the stability of the bar conveyor during the movement process.

[0012] Optionally, the fixing groove of the bar conveying block is connected to a clamping groove, which extends along the length of the bar conveying block. The clamping groove of the bar conveying block is provided with a bidirectional lead screw, and both ends of the bidirectional lead screw are threadedly connected to clamping plates for clamping the bar. The two clamping plates are arranged opposite to each other. One end of the bar conveying block is provided with a driving component for driving the bidirectional lead screw to rotate, and the driving component is connected to the bidirectional lead screw.

[0013] By adopting the above technical solution, when it is necessary to fix the bar stock in the bar stock conveying block, the operator starts the drive unit, which drives the bidirectional lead screw to rotate, thereby causing the two clamping plates in the bar stock conveying block to move towards each other, thus achieving the clamping of the bar stock and improving the stability of the bar stock during the movement process.

[0014] Optionally, the driving component includes a gear and a linkage block. The linkage block is disposed on the side of the bar conveying table near the driving component and extends along the length of the bar conveying table. A rack is provided at one end of the linkage block near the connecting table. The gear is disposed at one end of the bar conveying block near the linkage block and meshes with the rack. A first driven wheel and a second driven wheel are provided in the side wall of the bar conveying block. The gear is coaxially and fixedly connected with the first driven wheel. The first driven wheel and the second driven wheel mesh with each other. The second driven wheel is coaxially and fixedly connected with a bidirectional lead screw.

[0015] By adopting the above technical solution, when the bidirectional lead screw needs to be driven by a drive component, the operator only needs to start the conveying cylinder. The conveying cylinder drives the bar conveying block to move, thereby causing the gear to rotate through the rack. The rotation of the gear drives the first driven wheel to rotate, the first driven wheel drives the second driven wheel to rotate, and the second driven wheel drives the bidirectional lead screw to rotate. This realizes the operation of clamping the bar during the movement of the bar conveying block. By starting the conveying cylinder, both the movement of the bar conveying block and the clamping of the internal bar are realized. The linkage is strong and it is conducive to improving work efficiency.

[0016] Optionally, elastic layers are provided on opposite sides of both clamping plates, and the elastic layers are evenly distributed.

[0017] By adopting the above technical solution, the elastic layer of the clamping plate will preferentially contact the bar during the clamping process, thereby avoiding the bar from being directly subjected to force, which would cause the bar to bend, deform or break, thus improving the integrity of the bar during the conveying process.

[0018] Optionally, both sides of the connecting platform are provided with a first baffle to prevent the bar stock from slipping, and the two first baffles are arranged opposite each other.

[0019] By adopting the above technical solution, the first baffle can effectively prevent the bar stock from slipping off the connecting platform during the process of moving the bar stock from the connecting platform to the bar stock conveying platform, which helps to improve the safety of the bar stock during the movement process.

[0020] Optionally, the bar conveying block is provided with limiting plates on the side away from the connecting table and at both ends of the bar conveying block to prevent the bar from slipping.

[0021] By adopting the above technical solution and setting a limit plate, the situation where the bar stock falls off the bar stock conveyor block due to excessive speed during the falling process can be avoided, which is conducive to improving the safety of the bar stock conveying process and improving the integrity of the bar stock.

[0022] In summary, this application includes at least one of the following beneficial technical effects of the bar stock conveying device: By setting up a bar conveying platform, bar conveying station, connecting platform, base plate, fixed plate, sliding block, pushing cylinder, support, and lifting cylinder, when the operator needs to transfer and push the bar into the extrusion equipment, the operator first places the bar in the arc groove of the bar conveying platform, and then starts the lifting cylinder. The piston rod of the lifting cylinder drives the support plate to rise, which in turn drives the three support plates to rise, so that the height of the bar is higher than the height of the worktable, thereby realizing the rise of the bar. Then the operator starts the pushing cylinder, which drives the sliding block to move, so that the bar is above the connecting platform. Then the lifting cylinder is started again, so that the support plates are retracted into the device, and the bar falls off the support plates, slides on the inclined surface of the worktable, and enters the bar conveying block of the bar conveying platform. Then the bar is transported to the designated position by the conveying block. No pressure is applied directly to the bar throughout the process, which avoids the bar bending, deformation or breakage caused by pressure during transportation, and helps to improve the integrity of the bar during transportation. By setting up gears, linkage blocks, racks, first driven wheels, and second driven wheels, when a drive component is needed to drive the bidirectional lead screw to rotate, the operator only needs to start the conveying cylinder. The conveying cylinder drives the bar conveying block to move, thereby causing the gears to rotate through the rack. The rotation of the gears drives the first driven wheel to rotate, the first driven wheel drives the second driven wheel to rotate, and the second driven wheel drives the bidirectional lead screw to rotate. This achieves the operation of clamping the bar during the movement of the bar conveying block. By starting the conveying cylinder, both the movement of the bar conveying block and the clamping of the internal bar are achieved. The linkage is strong and helps to improve work efficiency. By setting an elastic layer, the clamping plate will preferentially contact the bar stock during the clamping process, thereby avoiding the bar stock from being directly subjected to force, which would cause the bar stock to bend, deform or break, thus improving the integrity of the bar stock during the conveying process.

[0027] The present application will be further described in detail below with reference to all the accompanying drawings.

[0028] This application discloses a bar transport device.

[0029] Reference Figure 1 A bar stock conveying device includes a bar stock conveying platform 1, a bar stock conveying component 2, and a connecting platform 3. The bar stock conveying platform 1 is horizontally arranged, the bar stock conveying component 2 is located at one end of the bar stock conveying platform 1, and the connecting platform 3 is located between the bar stock conveying platform 1 and the bar stock conveying component 2. Both ends of the connecting platform 3 are connected to the bar stock conveying platform 1 and the bar stock conveying component 2, respectively. The bar stock conveying platform 1 supports and fixes the bar stock and transports the bar stock to the connecting platform 3. The bar stock conveying component 2 transports the bar stock block 22 to a designated position. The connecting platform 3 serves as a slide for the bar stock between the bar stock conveying component 2 and the bar stock conveying platform 1.

[0030] Reference Figure 1The bar conveying platform 1 includes a base plate 11, a fixed plate 12, and a connecting plate 13. The base plate 11 is horizontally arranged, and the fixed plate 12 is vertically arranged on the upper surface of the base plate 11, with the fixed plate 12 located at one end of the base plate 11. The connecting plate 13 is located between the fixed plate 12 and the connecting platform 3, and is located at the top of the fixed plate 12. An arc-shaped groove is formed on the upper surface of the connecting plate 13, and three abutment holes are formed on the connecting plate 13, all extending along the length of the connecting plate 13. A moving groove is formed on the upper surface of the base plate 11, and a moving block 14 is slidably connected to the moving groove. A pushing cylinder 15 is provided on the side of the fixed plate 12, and the piston rod of the pushing cylinder 15 passes through the fixed plate 12. The fixed plate 12 is fixedly connected to the movable block 14. The movable block 14 is slidably connected to the movable groove of the base plate 11. The top of the movable block 14 is provided with three support plates 16 for supporting the bar stock. The top of the three support plates 16 are matched with the arc groove of the connecting plate 13. The support plates 16 are slidably connected to the abutment holes of the connecting plate 13. The upper end of the movable block 14 is provided with two lifting cylinders 17. The end of the lifting cylinder 17 away from the movable block 14 is provided with a support plate 18. The bottom ends of the three support plates 16 are fixedly connected to the support plate 18. The connecting platform 3 is provided with three movable grooves at the end near the bar stock conveying platform 1. The three movable grooves are respectively connected to the arc groove of the connecting plate 13.

[0031] Reference Figure 1 When the operator needs to transfer and push the bar stock into the extrusion equipment, the operator first places the bar stock in the arc-shaped groove of the bar stock conveying platform 1, and then activates the lifting cylinder 17. The piston rod of the lifting cylinder 17 drives the support plate 18 to rise, which in turn drives the three support plates 16 to rise, so that the height of the bar stock is higher than the height of the worktable, thereby realizing the rise of the bar stock. Then the operator activates the pushing cylinder 15, which drives the moving block 14 to move, so that the bar stock is above the connecting platform 3. Then the lifting cylinder 17 is activated again, so that the support plates 16 are retracted into the device, and the bar stock is detached from the support plates 16, thereby sliding on the inclined surface 31 of the worktable and entering the bar stock conveying component 2. Then the bar stock is transported to the designated position. No pressure is directly applied to the bar stock throughout the process, which avoids the bar stock being compressed during transportation, thus preventing bending, deformation or breakage of the bar stock and improving the integrity of the bar stock during transportation.

[0032] Reference Figure 2 and Figure 3The bar conveyor 2 includes a bar conveying platform 21 and a bar conveying block 22. The upper surface of the bar conveying platform 21 has two sliding grooves, both extending along the length of the platform. The lower surface of the bar conveying block 22 has two sliding blocks 23, located at the sliding grooves of the bar conveying platform 21. The top of the bar conveying block 22 has a fixing groove for placing bars, extending along its length. A conveying cylinder 24 is installed inside the connecting platform 3. The piston rod of the conveying cylinder 24 is fixedly connected to the end of the bar conveying block 22 near the connecting platform 3, and the piston rod is perpendicular to the end of the bar conveying block 22 near the connecting platform 3. The bar conveying block 22 is slidably connected to the connecting platform 3. On the upper end face of the bar conveying table 21, a clamping groove is connected to the fixing groove of the bar conveying block 22. The clamping groove extends along the length of the bar conveying block 22. A bidirectional lead screw 25 is provided at the clamping groove of the bar conveying block 22. Both ends of the bidirectional lead screw 25 are threadedly connected to clamping plates 26 for clamping the bar. The two clamping plates 26 are arranged opposite to each other. One end of the bar conveying block 22 is provided with a driving component 27 for driving the bidirectional lead screw 25 to rotate. The driving component 27 is connected to the bidirectional lead screw 25. Elastic layers 28 are provided on the opposite sides of the two clamping plates 26. The elastic layers 28 are made of rubber and are evenly distributed. Limiting plates 29 are provided on the side of the bar conveying block 22 away from the connecting table 3 and at both ends of the bar conveying block 22 to prevent the bar from slipping.

[0033] Reference Figure 2 and Figure 3 By setting the limiting plate 29, the situation where the bar stock falls off the bar stock conveying block 22 due to excessive speed can be avoided. During the sliding process of the bar stock conveying table 21, the sliding blocks 23 will slide at the sliding groove of the bar stock conveying table 21, thereby restricting the movement direction of the bar stock conveying block 22. When the bar stock needs to be conveyed using the bar stock conveying block 22, the bar stock slides from the connecting table 3 into the fixed groove of the bar stock conveying block 22. Then, the operator starts the conveying cylinder 24. The piston rod of the conveying cylinder 24 drives the bar stock conveying block 22 to move, thereby conveying the bar stock. When the bar stock is transported to the designated position and needs to be fixed in the bar stock conveying block 22, the operator starts the drive unit 27. The drive unit 27 drives the bidirectional lead screw 25 to rotate, thereby causing the two clamping plates 26 in the bar stock conveying block 22 to move towards each other, thus clamping the bar stock and improving the stability of the bar stock during movement. During the clamping process, the elastic layer 28 of the clamping plate 26 will preferentially contact the bar stock, thereby avoiding the bar stock from being directly subjected to force, which could lead to bending, deformation or breakage, and thus improving the integrity of the bar stock during the conveying process.

[0034] Reference Figure 3The driving component 27 includes a gear 271 and a linkage block 272. The linkage block 272 is located on the side of the bar conveying table 21 near the driving component 27 and extends along the length of the bar conveying table 21. A rack 273 is provided at one end of the linkage block 272 near the connecting table 3. The gear 271 is located at one end of the bar conveying block 22 near the linkage block 272 and meshes with the rack 273. A first driven wheel 274 and a second driven wheel 275 are provided in the side wall of the bar conveying block 22. The gear 271 is coaxially and fixedly connected to the first driven wheel 274 and the second driven wheel 275. The first driven wheel 274 and the second driven wheel 275 mesh with each other. The second driven wheel 275 is coaxially and fixedly connected to the bidirectional lead screw 25.

[0035] Reference Figure 2 and Figure 3 When the drive component 27 is needed to drive the bidirectional lead screw 25 to rotate, the operator only needs to start the conveying cylinder 24. The conveying cylinder 24 drives the bar conveying block 22 to move, thereby causing the gear 271 to rotate through the rack 273. The rotation of the gear 271 drives the first driven wheel 274 to rotate, the first driven wheel 274 drives the second driven wheel 275 to rotate, and the second driven wheel 275 drives the bidirectional lead screw 25 to rotate. This realizes the operation of clamping the bar during the movement of the bar conveying block 22. By starting the conveying cylinder 24, both the movement of the bar conveying block 22 and the clamping of the internal bar are realized. The linkage is strong and it is conducive to improving work efficiency.

[0036] Reference Figure 1 and Figure 2 The upper surface of the connecting platform 3 is set as an inclined surface 31, and both sides of the connecting platform 3 are provided with first baffles 32 to prevent the bar stock from slipping. The two first baffles 32 are arranged opposite to each other. By setting the inclined surface 31, the bar stock can roll into the bar stock conveying block 22 below. During the process of the bar stock moving from the connecting platform 3 to the bar stock conveying platform 21, the first baffles 32 can effectively prevent the bar stock from slipping off the connecting platform 3, which helps to improve the safety of the bar stock movement process.

[0037] The implementation principle of a bar stock conveying device according to an embodiment of this application is as follows: When the operator needs to convey and push the bar stock into the extrusion equipment, the operator first places the bar stock in the arc-shaped groove of the bar stock conveying platform 1, and then starts the lifting cylinder 17. The piston rod of the lifting cylinder 17 drives the support plate 18 to rise, which in turn drives the three support plates 16 to rise, so that the height of the bar stock is higher than the height of the worktable, thereby realizing the rise of the bar stock. Then the operator starts the pushing cylinder 15, which drives the sliding block 23 to move, so that the bar stock is above the connecting platform 3. Then the lifting cylinder 17 is started again, so that the support plates 16 are retracted into the device, and the bar stock falls off the support plates 16, slides on the inclined surface 31 of the worktable, and enters the fixed groove of the bar stock conveying block 22. Then the device is started. The conveying cylinder 24 drives the bar conveying block 22 to move, thereby causing the gear 271 to rotate through the rack 273. The rotation of the gear 271 drives the first driven wheel 274 to rotate, which in turn drives the second driven wheel 275 to rotate. The second driven wheel 275 then drives the bidirectional lead screw 25 to rotate, thus enabling the bar conveying block 22 to clamp the bar during its movement. By activating the conveying cylinder 24, both the movement of the bar conveying block 22 and the clamping of the internal bar are achieved. This strong linkage improves work efficiency. The bar is then transported to the designated location without any pressure acting directly on it, preventing the bar from bending, deforming, or breaking due to pressure during transportation and thus improving the integrity of the bar during transport.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
