Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle technology, and in particular to an aluminum extrusion die structure for a new energy vehicle chassis shock absorber. Background Technology

[0002] Extrusion is a pressure processing method that uses a punch or die to apply pressure to a blank placed in a die, causing it to flow plastically and thus obtaining a part corresponding to the shape of the die's cavity or punch. During extrusion, the blank generates triaxial compressive stress, and even blanks with low plasticity can be extruded into shape. Nowadays, most aluminum profile forming technologies utilize extrusion dies. Extrusion is mainly used for metal forming, and with the increasing popularity of new energy vehicles, the demand for aluminum profiles for new energy vehicle shock absorbers is also increasing year by year.

[0003] Chinese Patent Authorization Announcement No.: CN 209424317 U, Authorization Announcement Date: September 24, 2019. This utility model proposes an extrusion mold for aluminum profiles of shock absorbers for new energy vehicles. The mold includes an extrusion chamber with an extrusion punch at one end and a movable block at the other end. The outer wall of the movable block is fitted against the inner wall of the other end of the extrusion chamber, and an electric push rod is connected to the other end of the movable block. The lower end of the electric push rod has a base. The shortcomings of this technical solution are: 1. The presence of the movable block results in insufficient flatness of the extruded workpiece, requiring secondary processing; 2. Low material feeding efficiency, which is not conducive to batch operations.

[0004] In summary, extrusion dies suffer from poor extrusion effect and low efficiency. Utility Model Content

[0005] This invention aims to overcome the shortcomings of existing extrusion dies, such as poor extrusion effect and low efficiency, and provides a structure for an aluminum extrusion die for new energy vehicle chassis shock absorbers that improves extrusion effect and efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A structure for an aluminum extrusion die for shock absorbers in a new energy vehicle chassis, comprising:

[0008] support;

[0009] The lower base is slidably connected to the bracket.

[0010] The upper template is arranged opposite to the lower base, and the upper template is connected to the support frame for lifting.

[0011] The forming mold has a limiting groove on its lower base, and the forming mold is fitted into the limiting groove.

[0012] A rotating shaft is connected to a shaping mold, and the shaping mold is rotatably connected to a support via the rotating shaft.

[0013] The material collection box is movably connected to the support frame.

[0014] The auxiliary feeding top block is rotatably connected to the support.

[0015] The support frame is equipped with a telescopic mechanism. The upper template is connected to the telescopic mechanism to reciprocate on the support frame, thereby controlling the distance to the lower base. The forming mold is used to place the aluminum billet. The upper template and the forming mold in the lower base cooperate to extrude and form shock absorbers for new energy vehicle chassis. The lower base is the support structure for the forming mold, which is a traditional split lower base. The lower base has two symmetrically arranged parts that support the forming mold during extrusion through limiting grooves, so that the forming mold can withstand the gravity during extrusion. At the same time, the forming mold is an integral structure to ensure the integrity of the workpiece forming. The lower base can be moved and removed so that the forming mold can rotate under the control of the rotating shaft, thereby unloading the formed workpiece under gravity, which quickly solves the problem of difficult workpiece removal. The collection box is connected to the support frame and can move so that it can move to the bottom of the forming mold and between the lower base during unloading, so that the workpiece falls into the collection box for collection, which facilitates efficient batch extrusion operations. The auxiliary unloading top block is connected to the support frame to assist the unloading of the workpiece by applying force. It achieves the effects of improving workpiece forming integrity, good extrusion effect, high material feeding efficiency, and facilitating batch operation.

[0016] Preferably, the support frame includes a worktable connected to several guide slides. The gaps between the guide slides serve as movable guide rails, and the lower bases are movably connected to these guide rails. The support frame is connected to a worktable, and the guide slides are equipped with several sets of guides for the movement of the structure via the movable guide rails between two guide slides. The two lower bases, including limiting grooves, are arranged in a mirror-like configuration to achieve relatively stable and precise movement of the two lower bases to support the shaping mold. This improves the accuracy and stability of the structural movement.

[0017] Preferably, the bracket is connected to an auxiliary support base, which in turn is connected to a rotating mechanism. The rotating mechanism is connected to a mounting plate, with one end of the rotating shaft connected to the mounting plate and the other end detachably connected to the shaping mold. The auxiliary support base on the bracket connects to the rotating mechanism, enabling the rotating mechanism to drive the connected mounting plate. The mounting plate then drives the rotating shaft, which in turn rotates the shaping mold. This improves the automation level and connection stability of the structural operation.

[0018] Preferably, the shaping mold has a supporting boss, which is integrally connected to the port of the shaping mold. The supporting boss is bolted to a retaining ring with a slot. A rotating shaft is connected to a insert, which engages with the retaining ring and the insert with the slot. The integral supporting boss at the port of the shaping mold extends the surface structure of the mold outwards, preventing interference with the operation of the upper mold. The supporting boss is sleeved with the rotating shaft via a retaining block, and the insert engages with the slot. This allows the rotating shaft to rotate the retaining ring, which in turn rotates the shaping mold. The bolted connection between the retaining ring and the supporting boss facilitates disassembly and future maintenance of the shaping mold. This achieves improved structural connection stability and facilitates future maintenance.

[0019] Preferably, the collection box is slidably connected to the moving guide rail. The collection box is equipped with a buffer platform and an elastic mechanism. One end of the elastic mechanism is connected to the inner bottom of the collection box, and the other end is connected to one end of the buffer platform. A guide post is inserted into the buffer platform, and the elastic mechanism is sleeved with the guide post. The collection box is connected to a pair of guide slides and placed within the moving guide rail, allowing the collection box to move back and forth in a guided manner. The buffer platform is connected inside the collection box to buffer the impact force of workpieces falling into the collection box when the collection box is collecting workpieces from below, thanks to the elastic mechanism below the buffer platform. The buffer platform can move stably and elastically within the collection box via the guide post. This achieves the effect of improving the stability of the structural connection and protecting the workpieces.

[0020] Preferably, the other end face of the buffer platform is designed as a buffer ramp, and a buffer pad is connected to the buffer ramp. The upper end face of the buffer platform is also an inclined buffer ramp, and a soft buffer pad is connected to it. This achieves the effect of further protecting the workpiece and reducing operating noise.

[0021] Preferably, the buffer ramp is a rectangular surface with unequal heights on its two pairs of opposite sides. The buffer ramp is rectangular and slopes downwards to one side and from left to right to the other, thus buffering the falling workpieces while automatically gathering and organizing them. This further improves the efficiency of batch extrusion.

[0022] Preferably, the auxiliary feeding top block is equipped with a connecting rod. One end of the connecting rod is connected to a locking ring, and the other end of the connecting rod is connected to the auxiliary feeding top block. The locking ring is sleeved on the bracket. The auxiliary feeding top block is connected to the bracket via the locking ring on the connecting rod, making the auxiliary feeding top block easy to pick up and use. This allows for quick auxiliary feeding by utilizing the vibration generated when the auxiliary feeding top block strikes the shaping mold. This improves the stability of the structural connection and ensures the efficiency of the feeding operation.

[0023] The beneficial effects of this utility model are: the extrusion die improves the integrity of workpiece forming and has a good extrusion effect; it has high material feeding efficiency and facilitates batch operation; it improves the accuracy and stability of structural movement; it improves the stability of structural connection and facilitates later maintenance; it protects the workpiece and reduces operating noise.

The support boss 15 is bolted with a retaining ring 16. The retaining ring 16 is provided with a slot 17. The rotating shaft 6 is connected with an insert 18. The rotating shaft 6 is inserted into the retaining ring 16, and the insert 18 is inserted into the slot 17.

[0038] like Figure 5 As shown, the collection box 7 is slidably connected to the moving guide rail 11. The collection box 7 is provided with a buffer platform 19 and an elastic mechanism 20.

The buffer platform 19 is inserted with a guide post 21, and the elastic mechanism 20 is sleeved with the guide post 21.

[0039] like Figure 5 As shown, the other end face of the buffer platform 19 is set as a buffer slope 22, and a buffer pad 23 is connected to the buffer slope 22. The buffer slope 22 is a rectangular surface, and the two pairs of opposite sides of the buffer slope 22 are not of equal height.
