Description

Technical Field

[0001] This utility model relates to the field of aluminum profile extrusion die technology, and in particular to an industrial aluminum profile extrusion die that prevents workpieces from flying out. Background Technology

[0002] Industrial aluminum profile extrusion dies designed to prevent workpieces from flying out are special dies designed to ensure stable forming of aluminum profiles during high-speed extrusion and to prevent uncontrolled metal flow that could lead to workpiece splashing or breakage. They are commonly used in the construction, new energy vehicle, and photovoltaic industries.

[0003] In the existing industrial aluminum profile extrusion process, due to the high pressure and high speed operating environment of extrusion molding, and the sudden release of the huge internal stress remaining in the long tail material after the extrusion is completed, the tail workpiece may be accidentally thrown out, causing personal injury, equipment damage or production interruption.

[0004] To address the aforementioned issues, we propose an industrial aluminum profile extrusion die that prevents workpieces from flying out. Utility Model Content

[0005] The purpose of this utility model is to solve the problems in the background art by proposing an industrial aluminum profile extrusion die that prevents workpieces from flying out.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an industrial aluminum profile extrusion die for preventing workpieces from flying out, comprising a base, an upper die and a lower die provided in the recess of the base, the upper die and the lower die cooperating with each other, a frame provided on the upper surface of the base, a motor fixedly connected to the outer wall of the frame via a support plate, the output end of the motor passing through the frame, a slide groove fixedly connected to the inner wall of the frame, a reciprocating lead screw provided inside the slide groove, the end of the reciprocating lead screw being fixedly connected to the output end of the motor, a slider threadedly connected to the outer wall of the reciprocating lead screw, a cutting blade fixedly connected to the end of the slider, the cutting edge of the cutting blade being adjacent to the discharge end face of the lower die.

[0007] In the above-mentioned industrial aluminum profile extrusion die for preventing workpieces from flying out, two locking mechanisms are symmetrically arranged on the outer wall of the base. The locking mechanism includes a cylinder on the outer wall of the base. The piston rod of the cylinder is rotatably connected to a pulling rod. The pulling rod is fixedly connected to a locking rod. The locking rod cooperates with the lower die.

[0008] In the above-mentioned industrial aluminum profile extrusion die for preventing workpieces from flying out, the discharge end face of the lower die is provided with a roller conveyor, and a protective cover is fixedly connected to the surface of the roller conveyor.

[0009] In the above-mentioned industrial aluminum profile extrusion die for preventing workpieces from flying out, the discharge end face of the lower die is provided with a recycling box, and the lower surface of the recycling box is rotatably connected with casters.

[0010] In the above-mentioned industrial aluminum profile extrusion die for preventing workpieces from flying out, the surface of the roller conveyor is provided with a waste outlet, which corresponds to the inlet of the recycling bin.

[0011] In the above-mentioned industrial aluminum profile extrusion die for preventing workpieces from flying out, the cutting blade is provided with a splash guard, which is fixedly installed on the outer wall of the base.

[0012] Compared with existing technologies, the advantages of the industrial aluminum profile extrusion die for preventing workpieces from flying out provided by this utility model are as follows: 1. After the aluminum profile is extruded from the discharge end face of the lower die, just before the traction machine is about to release the constraint, the motor starts, driving the reciprocating screw to rotate, realizing the slider to make vertical reciprocating motion along the slide groove, thereby driving the cutting blade to cut the root of the aluminum profile at the discharge end face of the lower die. By shortening the length of the scrap section to the extreme, it loses the space for macroscopic elastic deformation, and the elastic potential energy stored inside cannot be converted into kinetic energy of violent motion, only micro-deformation can occur, thus fundamentally solving the safety hazard of the workpiece flying out; 2. After the aluminum profile is extruded from the discharge end face of the lower die, it moves forward along the roller conveyor. The protective cover constrains the tail end that has not yet entered the roller conveyor into the internal space. Its weak jumping energy is quickly dissipated by the inner wall of the protective cover, preventing the ejection accident caused by the stress release at the tail end of the workpiece and ensuring operational safety. In summary, this invention transforms the dangerous problem of long tail material ejection into a safe problem of short waste material disposal by actively cutting at the root of the mold's discharge end face, effectively ensuring the safety of operators and equipment and improving production efficiency.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figures 1-3 An industrial aluminum profile extrusion die for preventing workpieces from flying out includes a base 1. An upper die 2 and a lower die 3 are provided in the recess of the base 1. The upper die 2 and the lower die 3 cooperate with each other. A frame 4 is provided on the upper surface of the base 1. A motor 6 is fixedly connected to the outer wall of the frame 4 through a support plate 5. The output end of the motor 6 passes through the frame 4. A slide groove 19 is fixedly connected to the inner wall of the frame 4. A reciprocating screw 7 is provided inside the slide groove 19. The end of the reciprocating screw 7 is fixedly connected to the output end of the motor 6. A slider 8 is threadedly connected to the outer wall of the reciprocating screw 7. A cutting blade 9 is fixedly connected to the end of the slider 8. The cutting edge of the cutting blade 9 is adjacent to the discharge end face of the lower die 3. When the aluminum profile is extruded from the discharge end face of the lower die 3 and before the traction machine is about to release the constraint, the motor 6 starts and drives the reciprocating screw 7 to rotate, so that the slider 8 makes vertical reciprocating motion along the slide groove 19, thereby driving the cutting blade 9 to cut the root of the aluminum profile at the discharge end face of the lower die 3. By shortening the length of the waste section to the extreme, it loses the space for macroscopic elastic deformation. The elastic potential energy stored inside cannot be converted into kinetic energy for violent movement, and can only undergo slight deformation, thus fundamentally solving the safety hazard of the workpiece flying out.

[0017] Two locking mechanisms are symmetrically arranged on the outer wall of the base 1. The locking mechanism includes a cylinder 10 on the outer wall of the base 1. The piston rod of the cylinder 10 is rotatably connected to a pulling rod 11. The pulling rod 11 is fixedly connected to a locking rod 12. The locking rod 12 cooperates with the lower mold 3. Before the mold starts working, the cylinder 10 pulls back the piston rod, which drives the pulling rod 11 to descend, so that the locking rod rotates counterclockwise, thereby pressing and locking the lower mold 3 with the locking rod, improving the overall stability of the mold and reducing the risk of mold and workpiece displacement.

[0018] The lower die 3 has a roller conveyor 13 on its discharge end face. A protective cover 14 is fixedly connected to the surface of the roller conveyor 13. After the aluminum profile is extruded from the discharge end face of the lower die 3, it moves forward along the roller conveyor 13. The protective cover 14 constrains the tail end that has not yet entered the roller conveyor 13 into the internal space. Its weak jumping energy is quickly dissipated by the inner wall of the protective cover, preventing the ejection accident caused by the stress release at the tail end of the workpiece and ensuring operational safety.

[0019] The lower die 3 has a recycling box 15 at the discharge end face. The lower surface of the recycling box 15 is rotatably connected to a caster wheel 16. The surface of the roller conveyor 13 has a waste outlet 17, which corresponds to the inlet of the recycling box 15. When a new round of extrusion begins, the extremely short waste section is pushed out of the discharge end face of the lower die 3 by the new aluminum rod and falls directly into the recycling box 15 through the waste outlet 17, thus realizing the automatic collection and centralized recycling of waste.

[0020] The cutting blade 9 is equipped with a splash guard 18, which is fixedly installed on the outer wall of the base 1. The splash guard 18 can limit the metal chips and sparks generated during cutting to a local area, further protecting the equipment and operators.

[0021] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
