Description

Cam type limit folding mechanism for battery case

technical field

The invention relates to a cam type limit folding mechanism for battery casings, belonging to the technical field of battery casing folding.

Background technique

At present, our commonly used computer batteries, mobile phone batteries, etc., have a thin layer of outsourcing side shells on the outside of the batteries. During production, in order to improve production efficiency and reduce production costs reasonably, the outsourcing side shells are contracted. The shell production steps mainly include: firstly produce the plane on which the outer shell is unfolded, and then fold the plane by an edge folding machine or manually, and finally obtain the outer shell. The commonly used edge folding machine has a complex structure and is not designed for outsourcing edge shells, so it is not very convenient to use, and the use cost and maintenance cost are relatively high.

Contents of the invention

In view of the above problems, the present invention provides a cam-type limit folding mechanism for battery casings, which has a simple structure and is easy to operate, and effectively controls the use cost and maintenance cost while ensuring production efficiency.

The technical scheme that the present invention takes is:

The cam-type limiting hemming mechanism for the battery case includes a workbench, on which a bottom mold for hemming is installed, and a mounting column is vertically fixed on the workbench on the right side of the bottom mold. A casing is installed horizontally on the column, and a rotating shaft is installed horizontally on the casing. A handle plate for rotation is installed on the right end of the rotating shaft, and a mounting bracket is fixed on the mounting column. The feature is that the corresponding bottom mold is directly above it. A hemming reset mechanism for hemming is provided. The hemming resetting mechanism includes a hemming knife and a transmission rod that moves up and down. The hemming knife is installed on the lower end of the transmission rod through the knife holder. The through hole through which the rod freely passes up and down, and the transmission rod passes through the through hole. A reset plate for the upward movement of the transmission rod is fixed horizontally on the upper end of the transmission rod. A rubber block is set on the transmission rod between the reset plate and the mounting bracket. A cam mechanism for power transmission is arranged between the transmission rod and the rotating shaft, the frame of the cam mechanism is installed on the mounting bracket, the follower of the cam mechanism is arranged vertically, and the follower overlaps with the center line of the transmission rod. The cam of the cam mechanism is installed on the rotating shaft, and the limit block is fixed by bolts on the bottom mold on the right side of the hemming knife, and the right side of the bottom mold (2) is close to the left side wall of the mounting column (6). The height of the workbench (1) is 900mm to 1100mm, and the installation column (6) is a solid square column. The workbench (1) includes a table top, and four support legs are evenly arranged at the bottom of the table top. There are stretch bars in between.

Compared with the prior art, the beneficial effects brought by the present invention are mainly:

Through the invention, the structure is simple, the operation is convenient, and the use cost and the maintenance cost are effectively controlled while ensuring the production efficiency. When in use, just place the corresponding folding knife of the outer shell that needs to be folded flat on the bottom mold, and then rotate the rotating shaft by rotating the handle plate, so that the follower on the cam mechanism moves downward, and finally pushes the The reset plate overcomes the elastic force of the rubber block to drive the transmission rod to move downward, and finally installs the hemming work under the cooperation of the hemming knife and the bottom mold, and the production cost of the cam mechanism equipment is lower. Under the function of the limit block, it is convenient to fold the edge of the product of the same size. It is no longer necessary to perform visual inspection or ruler measurement when folding the edge. It only needs that the folded side of the product is tightly pressed against the left side of the limit block every time the edge is folded. On the side wall, you can wait for products of the same size, which is more convenient to use and higher in production efficiency.

detailed description

Below in conjunction with accompanying drawing and embodiment, further elaborate the present invention. In the following detailed description, certain exemplary embodiments of the invention are described by way of illustration only. Needless to say, those skilled in the art would realize that the described embodiments can be modified in various different ways, all without departing from the spirit and scope of the present invention. Accordingly, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.
