Description

Technical Field

[0001] This utility model relates to the field of metal ingot cutting technology, specifically to a magnesium alloy chip breaking production line. Background Technology

[0002] Magnesium alloys are alloys composed of magnesium as a base and other elements. Due to their superior properties such as low density (approximately 2 / 3 that of aluminum alloys and 1 / 4 that of steel), high specific strength, and good heat dissipation, they are increasingly widely used in high-end manufacturing industries such as aerospace, new energy vehicles, and 3C electronics. In the production and processing of magnesium alloys, processing magnesium blocks into small particles is a crucial step, and cutting technology is commonly used due to its efficiency and precision. However, magnesium alloys have characteristics such as low melting points and high plasticity, and different magnesium alloys have different metallic compositions. During the cutting process, the particles cut from some magnesium alloy ingots are prone to sticking together. Sticking particles not only affect the quality of subsequent forming and processing and the performance of the final product, but may also clog equipment pipes and screens, significantly increasing equipment maintenance costs and placing considerable economic pressure on enterprises. Utility Model Content

[0003] This invention provides a magnesium alloy chip breaking production line to solve the technical problems in the prior art.

[0004] To solve the above problems, the magnesium alloy chip breaking production line provided by this utility model adopts the following technical solution: it includes a chip cutter, which is used to cut magnesium alloy ingots into magnesium alloy particles;

[0005] A chip breaker is connected to the discharge port of a chip cutter. The chip breaker is used to separate magnesium alloy particles that are stuck together.

[0006] Cyclone collector: The inlet of the cyclone collector is connected to the outlet of the chip breaker. The cyclone collector collects the dispersed magnesium alloy particles into the cyclone collector through negative pressure.

[0007] The vibrating screen is used to screen magnesium alloy particles. The feed inlet of the vibrating screen is connected to the discharge outlet of the cyclone collector.

[0008] As a further improvement, the chip cutter includes a frame, a chip cutting assembly mounted on one side of the frame, and a pusher assembly mounted on the other side of the frame. The pusher assembly is used to drive the magnesium alloy ingot to move, so that the magnesium alloy ingot moves toward the chip cutting assembly to cut the magnesium alloy ingot. The arrangement direction of the chip cutting assembly and the pusher assembly is defined as the left-right direction.

[0009] As a further improvement, the chip assembly includes a cutting roller rotatably mounted on a frame and a cutting motor mounted on the frame for driving the cutting roller to rotate.

[0010] As a further improvement, the pusher assembly includes a telescopic structure and a clamping structure, allowing the pusher assembly to clamp and move the magnesium alloy ingot left and right.

[0011] As a further improvement, the frame is also provided with a waste material hole for discharging waste material. A flap is provided at the waste material hole for controlling the opening and closing of the waste material hole. A waste material track is also provided below the waste material hole, so that the magnesium alloy ingot waste material can fall through the waste material hole to the waste material track for collection and recycling.

[0012] As a further improvement, a lifting mechanism for lifting magnesium alloy ingots is provided on the side of the frame, a material feeding structure that can move in the front-back direction is provided on the top of the frame, and a chip track is also provided on the frame.

[0013] As a further improvement, the chip breaker includes a base, a body mounted on the base, and an explosion-proof motor. The body has a cylindrical cavity, and a core is rotatably assembled inside the body. The core is connected to the explosion-proof motor, and the core is evenly distributed with material-dispersing blades.

[0014] As a further improvement, the inner wall of the cavity is provided with concave and convex surfaces.

[0015] As a further improvement, the mechanism has a conical structure, and the gap between the material handling blade at the feed inlet and the cavity is greater than the gap between the material handling blade at the discharge outlet and the cavity.

[0016] As a further improvement, the fan of the cyclone collector is a medium-pressure centrifugal fan, which enables the air pressure of the cyclone collector to collect the fine powder in the magnesium alloy particles while avoiding sucking the magnesium alloy particles away.

[0017] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0018] 1. This utility model, by setting up a chip breaker, can disperse the adhering magnesium alloy particles, ensuring product quality and preventing the adhering magnesium alloy from affecting the normal discharge of materials or causing damage to the equipment.

[0019] The inner wall of the chip breaker has a concave-convex structure, which can improve the dispersion effect of magnesium alloy particles. After the magnesium alloy particles enter the chip breaker, the material dispersing blade throws the magnesium alloy particles onto the concave-convex surface for high-frequency collision, so as to achieve the purpose of breaking the magnesium alloy particles.

[0020] The core of the chip breaker is conical. The gap between the material-dispersing blade and the cavity at the feed inlet is relatively large, which is conducive to feeding. The gap between the material-dispersing blade and the cavity at the discharge outlet is small, ensuring that each piece of magnesium alloy can be thrown onto the inner wall of the machine by the material-dispersing blade. This prevents a small number of adhered magnesium alloy particles from not being thrown away due to insufficient force caused by the large gap between the material-dispersing blade and the cavity.

[0021] 2. In this utility model, the feeding of magnesium alloy ingots is achieved through the cooperation of lifting mechanism, feeding structure and chip track. Its structure is relatively simple and reduces manufacturing cost.

[0022] In existing technology, after the lifting mechanism raises the magnesium alloy ingot to a set height, it grips the ingot with two jaws (two jaws are needed because the magnesium alloy ingot is long and narrow), and moves it to a set position. The pushing component then grips and pushes the ingot to move. In this invention, by creating a chip track on the frame, when the lifting mechanism raises the magnesium alloy ingot to the point where its bottom surface is flush with the upper surface of the frame, the pushing structure pushes the ingot into the chip track, eliminating the need for two jaws and reducing the manufacturing cost of the device.

[0023] 3. The blower of the cyclone collector of this utility model adopts a medium-pressure centrifugal fan, which can transport magnesium alloy particles into the cylinder of the cyclone collector while collecting fine powder generated during the processing, thus avoiding dust accumulation in the equipment. The reason for using medium pressure instead of high pressure is to avoid high pressure sucking away the target particles (i.e., magnesium alloy particles). Attached Figure Description

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0031] In the existing technology, the metal composition of different magnesium alloys varies. During the cutting process, the cut particles of some magnesium alloy ingots are prone to sticking together. The sticking particles can easily affect the quality of subsequent forming and processing and the performance of the final product.

[0032] To address the aforementioned problems, this invention utilizes a chip breaker to disperse adhered magnesium alloy particles, ensuring product consistency. Furthermore, this invention improves the chip breaker by incorporating a textured structure on its inner wall, enhancing the dispersion of magnesium alloy particles. Upon entering the chip breaker, the dispersing blades throw the particles onto the textured surface, resulting in high-frequency collisions that effectively break up the chips.

[0033] The core of the chip breaker is conical. The gap between the material-dispersing blade and the cavity at the feed inlet is relatively large, which is conducive to feeding. The gap between the material-dispersing blade and the cavity at the discharge outlet is small, ensuring that each piece of magnesium alloy can be thrown onto the inner wall of the machine by the material-dispersing blade. This prevents a small number of adhered magnesium alloy particles from not being thrown away due to insufficient force caused by the large gap between the material-dispersing blade and the cavity.
