Description

Technical Field

[0001] This utility model relates to the field of aluminum rod manufacturing technology, and in particular to a novel aluminum rod peeling knife for automatically curling waste materials. Background Technology

[0002] In the hot extrusion process of aluminum alloys, in order to improve the deformation capacity of aluminum alloys, the aluminum casting rod is generally heated to 500-530℃ before being placed into the die cylinder and extruded through the die to obtain the required shape.

[0003] The oxide scale formed during the casting process of aluminum alloy hot extrusion bars has high hardness, which easily causes wear on the extrusion cylinder and inclusions during subsequent extrusion. In order to reduce the damage of the die cylinder to the oxide scale generated during aluminum bar casting and improve the quality of the final product, it is generally necessary to remove the oxide scale on the surface of the aluminum casting bar before extrusion. The traditional method of removing the oxide scale of aluminum bars is generally to use a lathe turning method. This method has low production efficiency and high labor intensity. There is also an aluminum bar peeling device, which includes a base and a peeling knife set on the base. The peeling knife has a through hole for the aluminum bar after peeling to pass through and a cutting edge set at the end of the through hole for circumferential cutting of the aluminum bar to achieve a preset outer diameter. Because the temperature is high during cutting, the oxide scale peeled off from the aluminum bar is easy to stick to the cutting edge and is not easy to fall off due to its own weight. Therefore, the oxide scale needs to be peeled off the peeling knife manually to avoid affecting the processing of the next aluminum bar. The operation is cumbersome. At the same time, the peeled outer scale is thin and large in volume, which is not conducive to transportation and subsequent melting processing. Utility Model Content

[0004] The purpose of this utility model is to overcome the defects in the existing technology and provide a new type of aluminum rod peeling knife for automatically curling waste materials.

[0005] To achieve the above objectives, the technical solution of this utility model is to design a novel automatic aluminum rod peeling knife for curling waste materials, comprising a peeling knife body, wherein the peeling knife body has a through hole penetrating the body, one end of the through hole forms a peeling blade, and a plurality of annularly arranged cutting edges are provided on the side of the peeling knife body away from the end face of the through hole, the cutting edges protruding from the peeling knife body, and a plurality of annularly arranged guide strips are also provided on the side of the peeling knife body away from the end face of the through hole. One end of the peeling blade is integrally connected to a corresponding guide strip. A guide strip is also provided between two adjacent cutting blades. The end face of the guide strip near the peeling blade is a concave arc groove. A limiting ring is protruding at the end of the peeling knife body away from the peeling blade. A connecting hole is provided on the limiting ring. A first annular oil passage is provided inside the limiting ring and communicates with the connecting hole. A first oil injection hole is provided on the outer peripheral surface of the peeling knife body between two adjacent guide strips and communicates with the first oil passage. The opening of the first oil injection hole faces the peeling blade.

[0006] In a further preferred embodiment, the limiting ring is further provided with an annular second oil passage, the connecting hole is connected to the second oil passage, and the arc groove of the guide strip is also provided with a second oil injection hole that is connected to the second oil passage respectively, with the opening of the second oil injection hole facing the peeling blade.

[0007] A further preferred technical solution is that a ball bearing is embedded in the end face of the second oil injection hole of each arc groove.

[0008] In a further preferred embodiment, the peeling blade is an annular peeling blade, which is formed on an annular conical surface at one end of the through hole. The annular conical surface rises inward from the end face of the through hole along the length to the outer surface of the peeling blade body, and the annular conical surface forms a sharp blade at one end of the through hole.

[0009] In a further preferred embodiment, the cutting edge is prismatic, wherein one edge of the prismatic shape is the cutting edge, the cutting edge faces the end where the peeling edge is located, and the width of the cutting edge gradually increases in the axial direction.

[0010] The advantages and beneficial effects of this utility model are as follows: Since the peeling knife is made of the same material, it does not need to be welded, and the knife has higher precision; the peeling knife is equipped with a guide bar and a cutting edge, which makes the cut aluminum chips automatically roll into a ring-shaped whole, making it easy to collect aluminum chips; since the cutting edge has a certain thickness, it is more durable than the traditional blade, and the durability time is increased.

[0011] Cutting fluid can absorb and remove a large amount of heat generated during the cutting process, reduce the temperature of the cutting area, prevent the aluminum rod and peeling blade from overheating, reduce thermal deformation and peeling blade wear, and improve machining quality and peeling blade life.

Detailed Implementation

[0016] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0017] like Figure 1 As shown, a novel automatic aluminum rod peeling knife for curling waste includes a peeling knife body 10. The peeling knife body 10 has a through hole 11 penetrating the body. One end of the through hole 11 forms a peeling blade 14, which is used to cut the material. In one embodiment, the peeling blade 14 is an annular peeling blade, which is formed on an annular conical surface at one end of the through hole 11. The annular conical surface rises inward from the end face of the through hole 11 along the longitudinal direction to the outer surface of the peeling knife body 10. The annular conical surface forms a sharp blade at one end of the through hole 11, which can cause the material being cut to flip outward along the conical surface. Under the action of external force, the aluminum rod is squeezed into the through hole 11 of the peeling knife from the front of the peeling blade 14. The aluminum rod is cut by the peeling blade 14 to form an outer shape within the range limited by the inner contour of the through hole 11, and the oxide scale of the aluminum rod is peeled off from the aluminum rod by the annular conical surface.

[0018] Because the peeling blade 14 is a closed annular structure, the oxide scale also forms a complete annular structure, making it difficult for the oxide scale to fall off the aluminum rod. In order to make the oxide scale fall off, a number of annularly arranged cutting blades 12 are provided on the peeling blade body 10 on the side of the peeling blade 14 away from the end face of the through hole 11. The cutting blades 12 are protruding on the peeling blade body 10. In this way, when the oxide scale is turned outward along the annular conical surface, it is cut axially by the cutting blades 12, so that the annular oxide scale is cut into a number of fan-shaped oxide scales.

[0019] In one embodiment, the cutting edge 12 is prismatic, with one edge of the prismatic shape serving as the cutting edge. The cutting edge faces the end where the peeling edge 14 is located. The width of the cutting edge 12 gradually increases axially, thus giving the cutting edge 12 good cutting ability and good structural strength, making it less prone to deformation. Furthermore, the cutting edge 12 is disposed on the peeling edge 14 formed by the annular conical surface, that is, the cutting edge 12 protrudes from the peeling edge 14. This allows the oxide scale to be turned outward along the peeling edge 14 while being divided into several pieces by the cutting edge 12.

[0020] On the side of the peeling blade 14 away from the end face of the through hole 11, there are several annularly arranged guide strips 15. The end of the cutting blade 12 away from the peeling blade 14 is connected to a corresponding guide strip 15 to improve the strength of the cutting blade 12 and enable it to withstand the pressure generated by cutting. A guide strip 15 is provided between two adjacent cutting blades 12. The end face of the guide strip 15 near the peeling blade 14 is a concave arc groove 13. This allows the oxide scale of the aluminum rod to form a curled shape, avoiding the accumulation of waste material and reducing the difficulty of descraping.

[0021] like Figure 2 As shown, the peeling knife body 10 has a limiting ring 16 at one end away from the peeling blade 14. The limiting ring 16 has a connecting hole 17. The limiting ring 16 has an annular first oil passage 19 that communicates with the connecting hole 17. The outer circumferential surface of the peeling knife body 10 between two adjacent guide bars 15 has a first oil spray hole 20 that communicates with the first oil passage 19. The opening of the first oil spray hole 20 faces the peeling blade 14. When the peeling knife is working, cutting fluid is sprayed onto the peeling blade 14 through the first oil spray hole 20 to cool and lubricate the peeling blade 14 and the aluminum rod.

[0022] like Figure 3 As shown, the limiting ring 16 is also provided with an annular second oil passage 18. The connecting hole 17 is connected to the second oil passage 17. The arc groove 13 of the guide strip 15 is provided with a second oil injection hole 21, which is connected to the second oil passage 18. The opening of the second oil injection hole 21 faces the peeling blade 14. When the peeling blade is working, cutting fluid is sprayed into the arc groove 13 through the second oil injection hole 21 to lubricate the oxide scale to form a curled shape.

[0023] In order to form a rolled shape on the oxide scale and reduce the friction coefficient between the oxide scale and the arc groove, a ball bearing 22 is embedded on the end face of the second oil injection hole 21 of each arc groove 13. When the oxide scale forms an outward rolled shape along the arc groove 13, the oxide scale rolls and rubs against the ball bearing 22, which can reduce the friction coefficient between the oxide scale and the arc groove 13.

[0024] Cutting fluid absorbs and removes a large amount of heat generated during the cutting process, reducing the temperature of the cutting area, preventing overheating of the aluminum rod and the peeling blade 14, reducing thermal deformation and wear of the peeling blade 14, and improving machining quality and the life of the peeling blade 14. Simultaneously, cutting fluid forms a lubricating film during cutting, reducing cutting forces and friction, decreasing wear on the workpiece and tool, and improving cutting efficiency and surface quality. Furthermore, cutting fluid can flush the cutting area, removing chips, metal particles, and contaminants, maintaining the cleanliness and precision of the aluminum rod surface, and preventing the accumulation and adhesion of debris generated during cutting. The rust inhibitors in the cutting fluid protect the aluminum rod surface from oxidation and corrosion, preventing rust and damage during machining. In summary, the use of cutting fluid aims to improve machining efficiency and quality, and protect the peeling blade 14 and the environment.

[0025] During operation, the aluminum rod is ejected from the peeling blade by the ejector cylinder, thereby removing the oxide scale from the surface of the aluminum rod. The specific peeling steps are as follows: First, the aluminum rod is placed on the support platform. Then, the support platform moves along the base to one side of the peeling blade 14. Next, the pusher moves towards the peeling blade, causing the aluminum rod to press against the peeling blade 14. As the pusher moves, the peeling blade 14 performs a circumferential cut on the aluminum rod, causing the part of the aluminum rod outside the discharge hole to peel off the main body under the action of the peeling blade 14. The part of the aluminum rod inside the discharge hole enters the discharge hole and moves backward. When the aluminum rod is completely inside the discharge hole, the aluminum rod is peeled.

[0026] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
