Electric vehicle frame tube side wall boss extrusion molding mechanism

Abstract

This utility model provides an extrusion forming mechanism for a side wall boss on an electric vehicle frame tube fitting, including a base. A fixing block is fixedly installed at the top of the base. A convex groove is formed on the top of the fixing block. An insert is embedded on one side of the convex groove, and a fixing cylinder is fixedly installed on the other side of the convex groove. An inclined top block is fixedly installed at the bottom of the inside of the fixing cylinder, and an extrusion steel ball is placed at the top of the inclined top block. An extrusion assembly is provided at the top of the inside of the fixing cylinder. When extruding a side wall boss on an electric vehicle frame tube fitting, this extrusion forming mechanism pushes the extrusion steel ball into the inside of the frame tube fitting plug through the extrusion assembly. The extrusion of the steel ball forms a boss on the side wall of the electric vehicle frame tube fitting, ensuring not only the curvature of the boss but also the uniform force on the side wall of the electric vehicle frame tube fitting during the extrusion process, thus ensuring the curvature and quality of the formed boss.

Description

Technical Field

[0001] This utility model belongs to the field of electric vehicle frame processing technology, and relates to an extrusion molding mechanism for side wall bosses of electric vehicle frame tubes. Background Technology

[0002] The electric vehicle frame is an important component of the electric vehicle, directly affecting the structural strength and performance of the entire vehicle. In the production and processing of traditional electric vehicle frame tubes, in order to facilitate the connection between the tubes, the side walls of the electric vehicle frame tubes need to be processed. This is done by extruding the side walls of the electric vehicle frame tubes to form bosses, which facilitates the connection.

[0003] Traditional processing of side wall bosses on electric vehicle frame tubes mainly involves forming bosses through internal extrusion. However, existing side wall extrusion methods for electric vehicle frame tubes cannot guarantee uniform stress distribution within the tube, affecting the curvature of the boss formation. To address these issues, we designed an extrusion forming mechanism for side wall bosses on electric vehicle frame tubes. Summary of the Invention

[0004] The purpose of this invention is to provide an extrusion molding mechanism for the side wall bosses of electric vehicle frame tubes, so as to solve the problems mentioned in the background art.

[0005] The purpose of this utility model can be achieved through the following technical solution: an extrusion molding mechanism for the side wall boss of an electric vehicle frame tube, including a base, a fixing block fixedly installed at the top of the base, a convex groove opened at the top of the fixing block, an insert embedded on one side of the convex groove, a fixing cylinder fixedly installed on the other side of the convex groove, an inclined top block fixedly installed at the bottom of the inside of the fixing cylinder, an extrusion steel ball placed at the top of the inclined top block, an extrusion assembly provided at the top of the inside of the fixing cylinder, a frame tube insertion port opened on one side of the fixing block, and a through hole communicating with the frame tube insertion port opened on the side wall of the fixing cylinder.

[0006] In the above-mentioned electric vehicle frame tube sidewall boss extrusion forming mechanism, the frame tube insertion port has a frustum-shaped structure, and the top dimension of the frame tube insertion port is larger than the size of the extruded steel ball.

[0007] In the above-mentioned electric vehicle frame tube side wall boss extrusion molding mechanism, the extrusion assembly includes a push rod and a pressure block. The pressure block is fixedly installed at the top of the push rod, and the bottom of the push rod is inserted into the interior of the fixed cylinder.

[0008] In the above-mentioned electric vehicle frame tube side wall boss extrusion forming mechanism, the bottom of the push rod is provided with an inclined surface, and the inclined surface is symmetrical to the top inclined surface of the inclined block, and the inclined surface is in contact with the surface of the extruded steel ball.

[0009] In the above-mentioned electric vehicle frame tube side wall boss extrusion molding mechanism, an arc-shaped groove is provided on one side of the insert, and the outer surface of the fixing cylinder is in contact with the arc-shaped groove.

[0010] In the above-mentioned electric vehicle frame tube side wall boss extrusion molding mechanism, the top of the pressure block is fixedly connected to the telescopic end of the electric hydraulic cylinder.

[0011] Compared with the prior art, the advantages of the electric vehicle frame tube side wall protrusion extrusion forming mechanism of this utility model are as follows: When the extrusion forming mechanism extrudes the side wall protrusion of the electric vehicle frame tube, the extrusion assembly pushes the extrusion steel ball to move into the inside of the frame tube plug. The extrusion of the extrusion steel ball forms the protrusion on the side wall of the electric vehicle frame tube. This not only ensures the curvature of the protrusion, but also ensures that the side wall of the electric vehicle frame tube is subjected to uniform force during the extrusion process, thus ensuring the curvature and quality of the protrusion.

Detailed Implementation

[0018] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0020] Specifically, when the extrusion molding mechanism extrudes the protrusion on the side wall of the electric vehicle frame tube, it pushes the extrusion steel ball 11 into the inside of the frame tube plug through the extrusion assembly. The extrusion of the extrusion steel ball 11 forms the protrusion on the side wall of the electric vehicle frame tube, which not only ensures the curvature of the protrusion, but also ensures that the force on the side wall of the electric vehicle frame tube is uniform during the extrusion process.

[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the electric vehicle frame tube side wall boss extrusion forming mechanism of this utility model has a frame tube insertion port 3 with a frustum-shaped structure, and the top dimension of the frame tube insertion port 3 is larger than the dimension of the extruded steel ball 11.

The pressure block 8 is fixedly installed on the top of the push rod 7, the bottom of the push rod 7 is inserted into the interior of the fixed cylinder 6, and the top of the pressure block 8 is fixedly connected to the telescopic end of the electric hydraulic cylinder.

[0023] The bottom of the push rod 7 has an inclined surface, which is symmetrical to the top inclined surface of the inclined block 9, and the inclined surface is in contact with the surface of the extrusion steel ball 11.

[0024] Specifically, the pressing block 8 and the push rod 7 work together to push the extruded steel ball 11 downwards, while the inclined top block 9 at the bottom of the fixed cylinder 6 facilitates the movement of the extruded steel ball 11 to the side.

[0025] An arc-shaped groove is provided on one side of the insert 5, and the outer surface of the fixing cylinder 6 is in contact with the arc-shaped groove.

[0026] Specifically, the arc-shaped groove makes contact with the surface of the fixed cylinder 6, which facilitates the limiting and fixing of the fixed cylinder 6.

[0027] In specific implementation, when using the electric vehicle frame tube side wall boss extrusion forming mechanism, firstly, the base 1 is fixedly connected to the worktable, then the top of the pressure block 8 is connected to the telescopic end of the electric hydraulic cylinder, then one end of the electric vehicle frame tube is inserted into the inside of the frame tube insertion port 3, then the electric hydraulic cylinder is opened, and the pressure block 8 is pushed downward by the electric hydraulic cylinder, and the push rod 7 is pushed downward by the downward movement of the pressure block 8, and through the cooperation of the push rod 7 and the inclined top block 9, the extrusion steel ball 11 flows into the inside of the frame tube insertion port 3 through the through hole 10, and the end face side wall of the electric vehicle frame tube is extruded to form a boss.
