Description

Technical Field

[0001] This utility model relates to the field of automotive water tank radiator technology, specifically a roller-type follow-up punching and shearing water chamber pressing tooth mechanism. Background Technology

[0002] The mainboard of the radiator is one of the most important components in the automotive radiator assembly. In existing production technologies, the blanking process for the mainboard has the following drawbacks: the movement rhythm of the traditional punching and shearing mechanism and the roller mechanism are difficult to coordinate effectively, resulting in asynchronous punching action and blank conveying speed. This easily leads to problems such as punching position deviation, incomplete tooth shape, or material tearing, directly affecting the assembly accuracy and service life of the radiator mainboard. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a roller-type follow-up punching and shearing pressure chamber tooth mechanism, which achieves synchronization with the speed of the roller-type discharge roller to complete the punching effect of the material plate.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a roller-type follower punching and shearing pressure chamber tooth mechanism, including a fixed frame, a follower frame, a cam fixing seat, and an eccentric cam; the follower frame is disposed within the fixed frame and can slide horizontally back and forth; a punching and shearing lower die assembly is fixedly disposed on the base plate of the follower frame; the cam fixing seat is disposed within the follower frame and can slide vertically up and down; the lower end of the cam fixing seat is connected to a punching and shearing upper die assembly adapted to the punching and shearing lower die assembly; one side of the eccentric cam is connected to the cam fixing seat, and the other side of the eccentric cam is connected to the drive wheel through a connecting shaft.

[0005] A further improvement is that: the fixed frame has a horizontally arranged U-shaped structure, and the top plate and the end of the top plate of the fixed frame are respectively provided with horizontal slide rails; the follower frame has an L-shaped structure, and the bottom plate and side plate of the follower frame are respectively connected to the corresponding horizontal slide rails through sliders, thereby realizing the horizontal sliding of the follower frame back and forth.

[0006] A further improvement is that a vertical slide rail is provided on the inner side of the side plate of the follower frame, and the cam fixing seat is connected to the vertical slide rail through a lifting slide plate, thereby realizing the vertical sliding of the cam fixing seat up and down.

[0007] A further improvement is that a partition is vertically installed inside the fixed frame, dividing its interior into two working areas. The connecting shaft passes through the partition, and one end of the connecting shaft is connected to the drive wheel in one of the working areas, while the other end of the connecting shaft is connected to the eccentric cam in the other working area.

[0008] A further improvement is that: the lower die assembly includes a blanking plate and a concave die plate arranged sequentially from bottom to top; the upper die assembly includes a punch fixing seat and a punch fixing plate arranged sequentially from top to bottom, the lower end of the punch fixing seat is provided with a punching head, and the punch fixing plate, the blanking plate and the concave die plate are all provided with positioning holes adapted to the punching head.

[0009] A further improvement is that a positioning groove for the sheet material to pass through is provided between the concave template and the punch fixing plate.

[0010] A further improvement is that the concave template is provided with several guide posts, and the upper end of the guide posts slides through the punch fixing plate.

[0011] A further improvement is that the drive wheel is connected to an external roller mechanism, thereby achieving synchronization with the speed of the rollers discharged by the roller mechanism.

[0012] A further improvement is that the drive wheel is a sprocket, which is connected to an external roller mechanism via a synchronous chain.

[0013] A further improvement is that the bottom of the fixing frame is provided with pads.

[0014] The beneficial effects of this utility model are as follows: In this invention, the roller mechanism drives the eccentric camshaft to rotate 360 ​​degrees via a synchronous chain-driven drive wheel; the follower frame and cam fixing seat move in tandem with the eccentric camshaft. When the camshaft is at its highest eccentric point, the punch seat and punch fixing plate are raised, and conversely, when it is at its lowest point, the punch falls to achieve punching, thereby synchronizing with the speed of the roller mechanism's discharge rollers to complete the punching effect on the material plate.
