Description

Technical Field

[0001] This utility model belongs to the field of aluminum rod forming production technology, and in particular relates to an aluminum rod hot shearing mechanism in an aluminum rod extrusion forming production line. Background Technology

[0002] The aluminum rod extrusion production line is a core component of aluminum alloy profile manufacturing. Through precise thermodynamic processing, it transforms aluminum ingots into complex cross-section profiles required in fields such as construction, transportation, and electronics. The entire system forms a complete closed loop from raw material processing to finished product output, and its process design fully integrates materials science and precision manufacturing technology. From raw material intake to finished product output, each step of the production line undergoes rigorous thermodynamic control and mechanical balance calculations to ensure that the final profiles achieve industry-leading mechanical properties and dimensional accuracy. The aluminum rod shearing process mainly involves cutting aluminum rods heated to approximately 480℃ to a fixed length using a hot shearing machine. The shearing process must maintain a temperature of no less than 400℃ to prevent material hardening.

[0003] Comparing with Chinese Patent CN213033385U, a hot shearing device for aluminum bars in an aluminum profile extrusion production line is disclosed. The device includes a heating furnace, a shearing mechanism, and a controller. The shearing mechanism is located at the material output end of the heating furnace and is used to shear the aluminum bars output from the furnace. The shearing mechanism includes a frame, a hydraulic cylinder mounted on the frame, a shearing blade connected to the hydraulic cylinder, and a shearing die cooperating with the shearing blade. A receiving flip-plate mechanism is provided on the frame, and a receiving groove is located directly below the receiving flip-plate mechanism. The controller is located away from the heating furnace and the shearing mechanism. The controller has a first control button and a second control button. The first control button controls the start and stop of the output mechanism of the heating furnace, and the second control button controls the punching action of the hydraulic cylinder. The device features a simple structure, convenient operation, and good safety.

[0004] However, the aforementioned patent lacks a channel to support the hot aluminum rod as it moves in and out, and the lack of clamping reduces the shearing accuracy and can cause the hot aluminum rod to jump, leading to safety accidents. Therefore, a new device needs to be designed. Utility Model Content

[0005] The purpose of this invention is to provide an aluminum rod hot shearing mechanism for an aluminum rod extrusion molding production line to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A hot shearing mechanism for aluminum rods in an aluminum rod extrusion forming production line includes a cutting device for defining dimensions and cutting the aluminum rods, and a frame device for supporting and clamping the aluminum rods during feeding. The cutting device is mounted on the frame device. A discharge device for supporting the aluminum rods, cutting them, and flipping them for unloading is provided at the discharge end of the frame device. The frame device includes a main body, a first support at one end of the main body, and a discharge base at the end of the main body away from the first support. A clamp for pressing down and fixing the aluminum rods is provided above the first support. The cutting device includes a cutting frame with a through hole in the middle, a first hydraulic cylinder at the top of the cutting frame, a shearing blade at the bottom telescopic end of the first hydraulic cylinder, and a limiting component for sliding adjustment of the shearing size at the rear of the cutting frame; the unloading device includes a second bracket with a fixed rotating shaft mounted on it, a second support rotatably mounted on the fixed rotating shaft, and two second hydraulic cylinders symmetrically mounted on the front of the second support, which are respectively hinged to the second support and the unloading base.

[0008] Furthermore, the clamping assembly includes a first bracket, on which two third hydraulic cylinders are symmetrically mounted, and clamping blocks are mounted on the bottom telescopic ends of the third hydraulic cylinders.

[0009] Furthermore, the bottom of the clamping block is provided with a V-shaped groove.

[0010] Furthermore: the limiting component includes a limiting slide fixedly disposed behind the cutting frame, a limiting slide rod slidably installed in the middle of the limiting slide, and a locking pin installed on the limiting slide.

[0011] Furthermore, the limiting slide bar is horizontally positioned and is L-shaped.

[0012] Furthermore, both the first bracket and the second bracket are arc-shaped, with the arc of the second bracket being larger than that of the first bracket.

[0013] Furthermore, the bottoms of the first bracket, the second bracket, and the through hole are on the same horizontal line.

[0014] Compared with existing technologies, the beneficial effects are:

[0015] 1. The symmetrical pressing structure of V-groove clamping blocks and double third hydraulic cylinders enhances the fixing force on the heated aluminum rod, preventing the aluminum rod from sliding or vibrating during the shearing process and ensuring cutting accuracy. The arc design of the first bracket, together with the clamping components, further optimizes the aluminum rod support contact surface and reduces safety risks. Through precise positioning, stable clamping, automated unloading, and structural optimization, the efficiency and quality of aluminum rod shearing and the overall automation level of the production line are significantly improved.

[0016] 2. The second bracket is driven by a hydraulic cylinder to flip and unload, realizing the automatic transfer of the aluminum rod after shearing, reducing manual intervention and improving the continuity of the production line; the design of the first and second brackets being horizontally aligned with the bottom of the through hole ensures seamless connection of the aluminum rod feeding, cutting and unloading process, reducing the risk of jamming.

[0017] 3. Modular design (cutting device, frame device, unloading device) facilitates maintenance and functional expansion, reducing equipment downtime; L-shaped limit slide bar and arc bracket and other structural designs take into account strength and functionality, and are suitable for the working environment of high temperature aluminum bars;

[0018] 4. The adjustable and precise positioning of the aluminum rod cutting length is achieved through the cooperation of the limiting slide bar and the locking pin, ensuring the consistency of the cutting size and meeting different process requirements; the coordinated design of the through hole of the cutting frame and the limiting component avoids the deviation of the aluminum rod during cutting and improves the quality of the cutting surface.

[0028] In this embodiment: the frame device includes a main body 101, a first bracket 102 is provided at one end of the main body 101, and a discharge base 106 is provided at the end of the main body 101 away from the first bracket 102.

Then, the first bracket 103 supports the third hydraulic cylinder 104 to push the clamping block 105 down to press the aluminum rod tightly and fix it on the first bracket 102.
