Description
Technical Field
The invention relates to a shell trimming die tool.
Background
For various machines, the flatness of the casing, etc. has to be taken into account for the precision of installation and subsequent use, and the edges of the casing must be processed, at present, the common processing method is edging processing, and the method has large workload, high manpower consumption and high cost
And the precision is not easy to control, and people need a better way to complete the processing of the edge of the shell.
Disclosure of Invention
The invention aims to solve the technical problem of providing a shell trimming die tool.
The invention is realized by the following technical scheme:
the machine shell trimming die tool comprises a lower die plate, an upper die plate, a trimming die base, a pair of holding cylinders, a cylinder seat, a trimming die cutting edge, a side holding shell die, an upper die subplate and a lower pressing cylinder, wherein the pair of holding cylinders are connected with the side holding shell die and are symmetrically arranged on the lower die plate through the cylinder seat, the trimming die base is fixedly arranged on the lower die plate, the lower pressing cylinder is arranged above the upper die plate and is used for driving the upper die plate to press downwards, the upper die subplate is arranged below the upper die plate, a lower limiting column is arranged on the lower die plate, an upper limiting column is arranged on the upper die subplate, the lower limiting column and the upper limiting column are mutually matched and are used for supporting the upper die subplate, a stripper plate is further arranged between the upper die subplate and the upper die plate, time delay and lower pressing linkage is realized between the stripper plate and the upper die plate through a spring, the trimming die cutting edge comprises an upper cutting edge and, the lower cutting edge is fixed above the trimming die base, and the upper cutting edge is arranged below the upper die auxiliary plate and is linked with the stripper plate through a connecting rod.
The invention has the beneficial effects that:
the invention has the advantages of ingenious structure, high automation degree, stable operation of the shell, clean and neat edge cutting and worth of popularization.
Drawings
For ease of illustration, the invention is described in detail by the following specific examples and figures.
FIG. 1 is a schematic structural diagram of the present invention.
Detailed Description
As shown in fig. 1, the machine shell trimming die tooling comprises a lower template 1, an upper template 2, a trimming die base 3, a pair of tightly-holding cylinders 4, a cylinder seat 5, a trimming die cutting edge, a side tightly-holding machine shell die 7, an upper auxiliary template 8 and a pressing cylinder, wherein the pair of tightly-holding cylinders 4 are connected with the side tightly-holding machine shell die 7 and are symmetrically arranged on the lower template 1 through the cylinder seat 5, the trimming die base 3 is fixedly arranged on the lower template 1, the pressing cylinder is arranged above the upper template 2 and is used for driving the upper template 2 to press downwards, the upper auxiliary template 8 is arranged below the upper template 2, a lower limiting column 9 is arranged on the lower template 1, an upper limiting column 10 is arranged on the upper auxiliary template 8, the lower limiting column 9 and the upper limiting column 10 are matched with each other to support the upper auxiliary template 8, a stripper plate 11 is further arranged between the upper auxiliary template 8 and the upper template 2, and time delay linkage between the stripper plate 11 and the upper template 2 is realized through a spring 12, the trimming die cutting edge comprises an upper cutting edge 6.1 and a lower cutting edge 6.2, the lower cutting edge 6.2 is fixed above the trimming die base 3, and the upper cutting edge 6.1 is arranged below the upper die auxiliary plate 8 and is linked with the stripper plate 11 through a connecting rod.
When the trimming machine works, firstly, a workpiece is fixed on the lower cutting edge of the trimming die, then the two holding cylinders drive the side faces matched with the appearance of the workpiece of the machine shell to hold the machine shell tightly, then the pressing cylinders drive the upper template to press downwards, the upper template drives the stripper plate to press downwards in a delayed way through the spring until the upper cutting edge is matched with the lower cutting edge to cut off the waste edges on the workpiece of the machine shell, the trimming work is finished, then the pressing cylinders stop working, the upper template rebounds to the original position under the reaction force of the spring to wait for the next work, the trimming is further strengthened under the reaction force of the spring, and the flash can be reduced.
The above description is only an embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that are not thought of through the inventive work should be included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope defined by the claims.
