Description

Technical Field

[0001] The utility model relates to the technical field of new energy vehicles, in particular to an aluminum profile extrusion die for a left side beam of a battery pack of a new energy vehicle. Background Art

[0002] New energy vehicles are vehicles that use unconventional automotive fuels as their power source, and new energy vehicle battery packs use batteries as their core. After searching, the Chinese patent authorization number CN214556341U discloses an aluminum extrusion die for the left beam of a new energy vehicle battery pack. The aluminum extrusion die for the left beam of a new energy vehicle battery pack has eight feed holes on the surface of the upper die, which effectively solves the problem of low life of aluminum profiles for the left beam of traditional new energy vehicle batteries. It can effectively ensure the life of the extrusion die, better save the cost of extrusion production, and will not frequently damage the extrusion die. The overall structure is compact, but due to the thin thickness of the shunt bridge and the low structural strength, the shunt bridge will be deformed under the extrusion of the aluminum ingot during feeding, which will affect the profile feeding. Utility Model Content

[0003] In view of the shortcomings of the prior art, the utility model provides an aluminum profile extrusion die for the left beam of a new energy vehicle battery pack, which solves the problem in the background technology that the shunt bridge is thin and has low structural strength, and the shunt bridge will be deformed under the extrusion of the aluminum ingot during feeding, which in turn affects the feeding of the profile.

[0004] To achieve the above objectives, the utility model is implemented through the following technical solutions: an aluminum profile extrusion die for the left beam of a new energy vehicle battery pack, comprising a first die base, a shunt bridge, a cutter and a working belt, a shunt hole is opened on the top of the first die base, four shunt holes are provided, and a shunt bridge is provided between adjacent shunt holes, the outside of the first die base is rotatably connected to the outer die, and a crushing knife is welded on the top of the outer die, a die core is provided at the bottom of the first die base, the die core is inserted into the inside of the working belt, and there is a gap between the outer wall of the die core and the inner wall of the working belt, the working belt is opened at the bottom of the welding chamber, and the welding is provided inside the second die base.

[0005] Preferably, a cutter is embedded on the outer side of the top of the first die base. The cutter is a ring-shaped structure, and a waste groove is provided on the outer side of the cutter. The cross-section of the waste groove is a U-shaped structure. The surface of the aluminum ingot will form a curling edge through the waste groove while cutting, which is beneficial to avoid the cut waste being too long and contacting the aluminum ingot body to affect the feeding.

[0006] Preferably, the cutter is wedge-shaped and is regularly distributed in a circular shape at equal intervals on the top of the outer mold. The outer mold is driven to rotate by an external driving device, which in turn drives the cutter to rotate. While the cutter rotates, it can cut the waste inside the waste trough, which is beneficial to crushing the waste.

[0007] Preferably, the diverter bridge is in an arch-shaped structure, and both sides of the diverter bridge are chamfered, and the chamfered structure is helpful to reduce the resistance of the aluminum ingot entering the diverter hole.

[0008] Preferably, a buffer block is provided on the top of the diverter bridge, and the top of the buffer block is a conical structure. By providing the buffer block on the top of the diverter bridge, the conical structure of the buffer block is conducive to breaking the end of the aluminum ingot when the end of the aluminum ingot contacts the buffer block, thereby allowing the material to smoothly enter the diverter hole and reduce the resistance of the aluminum ingot.

[0009] Preferably, the outer side of the top of the diverter hole is chamfered, which is helpful to reduce the resistance between the material and the feed inlet of the diverter hole.

[0010] The utility model provides an aluminum profile extrusion die for the left side beam of a new energy vehicle battery pack. It has the following beneficial effects:

[0011] (1) An aluminum extrusion die for the left beam of a new energy vehicle battery pack is provided with four diverter holes, which is conducive to dispersing the material into the welding chamber. At the same time, by setting the top of the diverter bridge into an arch-shaped structure, when the aluminum ingot is fed, it will exert pressure on the top of the diverter bridge, and then the diverter bridge will disperse the pressure to both ends through the arch-shaped structure at the top. The pressure at both ends of the diverter bridge is supported by the first die base body, which is conducive to improving the pressure resistance of the diverter bridge, and thus helping to reduce the deformation probability of the diverter bridge. At the same time, by setting a buffer block on the top of the diverter bridge, the end of the aluminum ingot is facilitated to break the end of the aluminum ingot through the conical structure of the buffer block when it contacts the buffer block, so that the material can smoothly enter the diverter hole, reducing the resistance of the aluminum ingot.

[0012] (2) The aluminum profile extrusion die for the left side beam of the new energy vehicle battery pack is provided with an annular cutter on the top edge of the die, so that the outer surface of the aluminum ingot can be cut by the cutter when the aluminum ingot enters the diversion hole, so that the surface of the aluminum ingot can be peeled off, which is conducive to shaving off a thin layer on the surface of the aluminum ingot, thereby peeling off the outer layer of the raw material contaminated by external dust and particles, and effectively improving the subsequent product quality.

[0013] This solves the problem that the existing shunt bridge is thin, has low structural strength, and is deformed under the extrusion of the aluminum ingot during feeding, which in turn affects the feeding of the profile. BRIEF DESCRIPTION OF THE DRAWINGS
