Description

Technical Field

[0001] This utility model relates to the field of hot shearing furnace technology, specifically to a long bar hot shearing furnace for producing aluminum profiles for guide rails. Background Technology

[0002] A hot shearing furnace is a heating device used in the production of aluminum profiles. Its main function is to heat aluminum alloy bars (or ingots) for subsequent shearing. It heats the aluminum to a certain temperature, bringing it to a plastic state to ensure a smooth cutting process and improve the processing quality of the aluminum profiles.

[0003] According to a public announcement (publication number: CN214720030U), a long bar hot shearing furnace for producing aluminum profiles includes: a base plate, a heating furnace fixedly connected to one end of the top of the base plate, a conveying mechanism located at the end of the top of the base plate near the heating furnace, a shearing mechanism located at the end of the top of the base plate near the conveying mechanism, and a cooling mechanism located at the end of the top of the base plate near the shearing mechanism. The cooling mechanism includes a cooling box, which is fixedly connected to the end of the top of the base plate away from the heating furnace. A second hydraulic rod is fixedly and movably connected inside the cooling box, and a straightening plate is fixedly connected to the output end of the second hydraulic rod.

[0004] In the aforementioned application, the cooperation between the transport mechanism and the shearing mechanism makes it difficult to fix and clamp the processed aluminum material when it needs to be sheared. This may cause the aluminum material to shift during the shearing process, resulting in the shearing length not meeting the quality requirements. Therefore, we propose a long bar hot shearing furnace for producing aluminum profiles for guide rails. Utility Model Content

[0005] To overcome the above-mentioned defects, the present invention provides a long bar hot shearing furnace for producing aluminum profiles for guide rails, which solves the technical problem of poor precision caused by unstable clamping during the cutting process in the prior art.

[0006] According to one aspect, at least one embodiment of the present invention provides a long bar hot shearing furnace for producing aluminum profiles for guide rails, comprising: a cabinet, a workbench fixedly connected to the side of the cabinet, a motor fixedly connected to the side of the cabinet, a rotating shaft fixedly connected to the output end of the motor, a cutting blade fixedly connected to the circumferential surface of the rotating shaft, a discharge port opened on the side of the cabinet, a clamping device provided on the top of the workbench, and a heating block provided inside the cabinet; The clamping device includes a support frame, the bottom of which is fixedly connected to the top of the workbench.

This design helps to improve the cutting accuracy and working efficiency of the hot shear furnace.

[0007] For example, in at least one embodiment of this utility model, a long bar hot shearing furnace for producing aluminum profiles for guide rails further includes: a rotating shaft fixedly connected to the side of the motor; a rotating shaft rotatably connected to the side of the cabinet; a belt shaft fixedly connected to the circumferential surface of the rotating shaft one; a belt shaft fixedly connected to the circumferential surface of the rotating shaft two; a belt provided on the circumferential surface of the belt shaft one; the belt shaft one being connected to the belt shaft two via the belt shaft one; a knocking rod fixedly connected to the circumferential surface of the rotating shaft two; a water tank fixedly connected to the side of the cabinet; an extrusion plate slidably connected inside the water tank; a moving column fixedly connected to the bottom of the extrusion plate; a water supply pipe fixedly passing through the side of the water tank; and a water trough fixedly connected to the side of the workbench. This design helps improve the working efficiency of the hot shearing furnace and reduce equipment wear. A limit rod is fixedly connected to the side of the motor, and the circumferential surface of the limit rod passes through and slidably connects to the side of the threaded sleeve, the purpose of which is to prevent the threaded sleeve from rotating. A second spring is fixedly connected to the circumferential surface of the movable column. The end of the second spring away from the movable column is fixedly connected to the bottom of the water tank. A water inlet is provided at the top of the water tank to allow the second spring to drive the movable column to reset. The end of the water supply pipe away from the water tank is located directly above the water trough. A water outlet is provided on the side of the water trough to prevent water accumulation. Two threaded sleeves, connecting rods, and clamping plates are provided, symmetrically arranged along the vertical central axis of the worktable. One end of the movable column is located on the displacement trajectory of the striking rod, so that the striking rod can push the movable column upward.

[0008] According to another aspect, at least one embodiment of this utility model also provides a long bar hot shearing furnace for producing aluminum profiles for guide rails, comprising: a feeding device provided on the top of the workbench, the feeding device including a rotating shaft three, one end of the rotating shaft three being fixedly connected to one end of a reciprocating lead screw, a belt shaft three being fixedly connected to the circumferential surface of the rotating shaft three, a rotating shaft four being rotatably connected inside the workbench, a belt shaft four being fixedly connected to the circumferential surface of the rotating shaft four, a transmission belt being provided on the circumferential surface of the belt shaft three, the belt shaft three being connected to the belt shaft four via the transmission belt, and a conveyor belt being provided on the circumferential surface of the rotating shaft four. This design is beneficial to enhancing the stability and automation level of the overall equipment.

[0009] For example, in at least one embodiment of this utility model, a long bar hot shearing furnace for producing aluminum profiles for guide rails further includes: two rotating shafts (fourth shafts) symmetrically arranged along the vertical central axis of the worktable; each rotating shaft (fourth shaft) is connected to the other rotating shaft (fourth shaft) via a conveyor belt. This design facilitates the transportation of aluminum materials and reduces manual labor. A hydraulic cylinder is fixedly connected to the top of the worktable. One end of the hydraulic cylinder is slidably connected to a force-bearing rod via a piston, and the other end of the hydraulic cylinder is slidably connected to a hydraulic rod via another piston.

A spring (third spring) is fixedly connected to the side of the hydraulic cylinder. The end of the spring (third spring) away from the hydraulic cylinder is fixedly connected to the side of the push plate. One end of the force-bearing rod is located on the displacement trajectory of the clamping plate, the purpose of which is to allow the clamping plate to push the force-bearing rod to reset.

[0010] The beneficial effects of this utility model are as follows: In this invention, through the cooperation of components such as the motor, rotating shaft, and striking rod in the clamping device, when the worker puts the aluminum material into the cabinet, after the aluminum material is processed, it passes through the discharge port. The motor drives the reciprocating screw to rotate, which in turn drives the threaded sleeve, clamping plate, spring, and clamping plate to clamp the aluminum material. The motor drives the rotating shaft to drive the cutting blade to cut the aluminum material. The motor also drives the rotating shaft to drive the striking rod through the belt transmission system to push the moving column, thereby squeezing the water in the water tank. The water enters the water tank through the pipe, realizing the rapid cooling of the aluminum material. The water in the water tank flows out, completing the cooling treatment of the aluminum material. This achieves multiple clamping and cutting protection, ensuring processing accuracy.

[0011] In this invention, the aluminum material is transported through the coordinated operation of components such as the rotating shaft three, hydraulic cylinder, and push plate in the feeding device. The rotating shaft three drives the belt shaft three to rotate, which in turn drives the belt shaft four, and the rotating shaft four drives the conveyor belt. When the clamping plate completes clamping, it pushes the force rod, which in turn drives the hydraulic cylinder to push the push plate to feed the aluminum material. After feeding, the hydraulic rod is reset by the spring three, avoiding complex transportation and increased manual labor, thus facilitating the automatic transportation and feeding of aluminum materials and improving production efficiency.

A belt shaft 711 is fixedly connected to the circumferential surface of the rotating shaft 79, and a belt shaft 712 is fixedly connected to the circumferential surface of the rotating shaft 710. A belt 713 is provided on the circumferential surface of the belt shaft 711. The belt shaft 711 is connected to the belt shaft 712 via the belt 713. A knocking rod 714 is fixedly connected to the circumferential surface of the rotating shaft 710. A water tank 715 is fixedly connected to the side of the cabinet 1. An extrusion plate 716 is slidably connected inside the water tank 715. A moving column 717 is fixedly connected to the bottom of the extrusion plate 716. A water supply pipe 718 is fixedly passed through the side of the water tank 715. A water trough 719 is fixedly connected to the side of the workbench 2. This design helps to improve the working efficiency of the hot shear furnace and reduce equipment wear.

[0023] A limit rod 720 is fixedly connected to the side of the motor 72. The circumferential surface of the limit rod 720 passes through and is slidably connected to the side of the threaded sleeve 74. Its purpose is to prevent the threaded sleeve 74 from rotating.

[0024] A second spring 721 is fixedly connected to the circumferential surface of the movable column 717. The end of the second spring 721 away from the movable column 717 is fixedly connected to the bottom of the water tank 715. A water inlet 722 is opened on the top of the water tank 715. The purpose of this is to allow the second spring 721 to drive the movable column 717 to reset.

[0025] The end of the water pipe 718 away from the water tank 715 is located directly above the water trough 719. The side of the water trough 719 has an outlet to prevent water from accumulating in the water trough 719.

[0026] There are two threaded sleeves 74, connecting rods 75 and clamping plates 76, which are symmetrical to each other along the vertical central axis of the worktable 2. One end of the moving column 717 is located on the displacement trajectory of the knocking rod 714, so that the knocking rod 714 can push the moving column 717 to rise.

[0027] This embodiment provides a long bar hot shearing furnace for producing aluminum profiles for guide rails. In this utility model, through the cooperation of components such as the motor 72, rotating shaft 79, and striking rod 714 in the clamping device 7, when the worker puts the aluminum material into the cabinet 1, after the aluminum material is processed, it passes through the discharge port 6. The motor 72 drives the reciprocating screw 73 to rotate, which drives the threaded sleeve 74, clamping plate 76, spring 77, and clamping plate 78 to clamp the aluminum material. The motor 72 drives the rotating shaft 4 to drive the cutting blade 5 to cut the aluminum material. The motor 72 also drives the rotating shaft 79 to drive the striking rod 714 to push the moving column 717 through the belt 713 transmission system, thereby squeezing the water in the water tank 715. The water enters the water tank 719 through the pipe, realizing the rapid cooling of the aluminum material. The water in the water tank 719 flows out, completing the cooling treatment of the aluminum material. Multiple clamping and cutting protection are achieved to ensure processing accuracy.

[0028] See in some examples Figures 1-6 The reciprocating screw 73 drives the threaded sleeve 74 to rotate, thus achieving the effect of clamping the aluminum material. When the worker needs to process the aluminum material, the aluminum material is put in through the inlet of the cabinet 1. After the aluminum material is processed in the cabinet, it exits through the outlet 6. At this time, the motor 72 is started. The output end of the motor 72 drives the reciprocating screw 73 to rotate. During the rotation of the reciprocating screw 73, the threaded sleeve 74 is moved through the limit rod 720. During the movement of the threaded sleeve 74, the clamping plate 76 is driven through the connecting rod 75 to clamp the aluminum material. During the clamping process, the clamping plate 76 drives the spring 77 and the clamping plate 78 to clamp aluminum materials of different specifications. Then, the motor 3 is started. The output end of the motor 3 drives the rotating shaft 4 to rotate. During the rotation of the rotating shaft 4, the cutting blade 5 is driven to cut the processed aluminum material. The output end of the motor 72 drives the rotating shaft 79 to rotate. During the rotation, belt shaft 711 is driven to rotate. Belt shaft 711, in turn, drives belt shaft 712 via belt 713. Belt shaft 712, in turn, drives shaft 710. Shaft 710, in turn, drives lever 714 to push moving column 717. Moving column 717, in turn, drives extrusion plate 716 to extrude water from water tank 715. The water from water tank 715 then flows into water tank 719 through water pipe 718, achieving rapid cooling of the processed aluminum material. When lever 714 leaves moving column 717, moving column 717 returns to its original position due to the elasticity of spring 721. The water in water tank 719, after cooling the aluminum material, flows out through the outlet of water tank 719, thus achieving continuous cooling of the aluminum material, improving work efficiency, and reducing manual labor.

[0029] refer to Figures 1-6In some embodiments, a hot shearing furnace for producing aluminum profiles for guide rails further includes a feeding device 8. The feeding device 8 includes a rotating shaft 3 81, one end of which is fixedly connected to one end of a reciprocating lead screw 73. A belt shaft 3 82 is fixedly connected to the circumferential surface of the rotating shaft 3 81. A rotating shaft 4 83 is rotatably connected inside the worktable 2. A belt shaft 4 84 is fixedly connected to the circumferential surface of the rotating shaft 4 83. A transmission belt 85 is provided on the circumferential surface of the belt shaft 3 82. The belt shaft 3 82 is connected to the belt shaft 4 84 via the transmission belt 85. A conveyor belt 86 is provided on the circumferential surface of the rotating shaft 4 83. This design is beneficial to enhancing the stability and automation level of the overall equipment.

[0030] There are two rotating shafts 83, which are symmetrical to each other along the vertical central axis of the worktable 2. The rotating shafts 83 are connected to the other rotating shaft 83 through the conveyor belt 86. This design is beneficial for transporting aluminum materials and reduces manual labor.

[0031] A hydraulic cylinder 87 is fixedly connected to the top of the workbench 2. One end of the hydraulic cylinder 87 is slidably connected to a force rod 88 via a piston. The other end of the hydraulic cylinder 87 is slidably connected to a hydraulic rod 89 via another piston. A push plate 810 is fixedly connected to the end of the hydraulic rod 89 away from the hydraulic cylinder 87. This design is beneficial for cutting aluminum materials through the hydraulic cylinder 87.

[0032] A spring 811 is fixedly connected to the side of the hydraulic cylinder 87. The end of the spring 811 away from the hydraulic cylinder 87 is fixedly connected to the side of the push plate 810. One end of the force rod 88 is located on the displacement trajectory of the clamping plate 76. The purpose is to enable the clamping plate 76 to push the force rod 88 to reset.

[0033] In this embodiment, the aluminum material is transported through the cooperation of components such as the rotating shaft 81, hydraulic cylinder 87, and push plate 810 in the feeding device 8. The rotating shaft 81 drives the belt shaft 82 to rotate, the transmission belt 85 further drives the belt shaft 84, and the rotating shaft 83 drives the conveyor belt 86. When the clamping plate 76 completes clamping, it pushes the force rod 88, which in turn pushes the hydraulic rod 89 through the hydraulic cylinder 87, causing the push plate 810 to push the aluminum material out of the container. After the material is unloaded, the hydraulic rod 89 is reset by the spring 811. This avoids complex transportation and increases manual labor, helps to realize the automatic transportation and unloading of aluminum materials, and improves production efficiency.

[0034] In this embodiment, a feeding device 8 is provided on the workbench 2 to achieve the effect of feeding aluminum materials. During the rotation of the third rotating shaft 81, the third belt shaft 82 rotates. During the rotation of the third belt shaft 82, the fourth belt shaft 84 rotates via the transmission belt 85. During the rotation of the fourth belt shaft 84, the fourth rotating shaft 83 rotates. During the rotation of the fourth rotating shaft 83, another fourth rotating shaft 83 rotates via the conveyor belt 86, thereby achieving the effect of transporting the aluminum materials. After the clamping plate 76 clamps the aluminum, the clamping plate 76 moves and pushes the force rod 88. The force on the force rod 88 pushes the hydraulic rod 89 through the hydraulic cylinder 87. During the movement of the hydraulic rod 89, the push plate 810 moves, pushing the transported aluminum materials. After feeding is completed, the hydraulic rod 89 is reset by the elastic action of the third spring 811, thereby achieving the effect of feeding aluminum materials and improving overall work efficiency.
