Abstract
The utility model discloses a structure for fixing a small punching needle on a stripper plate. The structure for fixing the small punching needle on the stripper plate solves the problem that according to the prior art, fracture of needles can happen frequently in a stamping process. The structure for fixing the small punching needle on the stripper plate is characterized in that the structure for fixing the small punching needle on the stripper plate comprises the stripper plate, casting insert and the punching needle, a casting insert hole is wire-cut in the stripper plate, a punching needle hole is wire-cut in the casting insert, the assembling gap between one side of the casting insert and one corresponding side of the stripper plate is 0.005mm, the casting inset is divided into first casting insert and second casting insert, the total height of the first casting insert and the second casting insert is the same as the height of the stripper plate, the assembling gap between one side of the second casting insert and one corresponding side of the punching needle is 0.01mm, and the assembling gap between one side of the first casting insert and one corresponding side of the punching needle is 0.007mm. The punching needle is clamped by the first casting insert and the second casting insert at the same time in a production and stamping process, and therefore the frequency of the needle fracture is reduced. The structure for fixing the small punching needle on the stripper plate has the advantages that the frequency of the needle fracture is reduced, time is saved for mold maintenance staff, and the utilization rate of a punching machine is improved.
Description
Technical field
The utility model relates to a kind of diel field, relates in particular to the fixing little red needle structure of a kind of stripper plate.
Background technology
Red needle is the size of directly cutting its red needle at the stripper plate center line at the fixing means of stripper plate in the existing mould; and bore red needle in the front of stripper plate and keep away a hole; but it is smaller to meet some red needles; when product material is thicker; this fixing means red needle in the actual production punching course fractures through regular meeting, because the red needle material, line cuts precision; many-sided reasons such as product material is blocked up, the generation that in punching course, still can't thoroughly solve the broken needle problem.
Summary of the invention
The purpose of this utility model is: provide a kind of stripper plate to fix little red needle structure, have the problem that broken needle often takes place in the punching course to solve prior art.
Reaching the technical scheme that the purpose of this utility model takes is: a kind of stripper plate is fixed little red needle structure, it is characterized in that: comprise stripper plate, mold insert, red needle, described stripper plate line cuts the mold insert hole, described mold insert line cuts the red needle hole, fit-up gap between mold insert and the stripper plate is monolateral 0.005MM, wherein mold insert is divided into first mold insert, second mold insert, first mold insert, the total height of second mold insert equals the height of stripper plate, the fit-up gap of second mold insert and red needle is monolateral 0.01MM, and the fit-up gap of first mold insert and red needle is monolateral 0.007MM.When the production punching press, by first mold insert, second mold insert is kept a grip on red needle simultaneously, thereby reduces the number of times of broken needle.
The beneficial effect that the utility model reaches is: adopt the utility model by having reduced the number of times of broken needle, saved the personnel's that repair a die time, improved the utilization rate of punch press.
Description of drawings
Fig. 1: structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing structural representation of the present utility model is described more at large.
With reference to Fig. 1, a kind of stripper plate is fixed little red needle structure, it is characterized in that: comprise stripper plate 1, mold insert 2, red needle 3, described stripper plate 1 line cuts the mold insert hole, described mold insert 2 lines cut the red needle hole, fit-up gap between mold insert 2 and the stripper plate 1 is monolateral 0.005MM, and wherein mold insert 2 is divided into first mold insert, 21, the second mold inserts 22, first mold insert 21, the total height of second mold insert 22 equals the height of stripper plate 1, and second mold insert 22 is monolateral 0.01MM with the fit-up gap of red needle 3, and first mold insert 21 is monolateral 0.007MM with the fit-up gap of red needle 3.When the production punching press, first mold insert, 21, the second mold inserts 22 are kept a grip on red needle 3 simultaneously, thereby reduce the number of times of broken needle.
Should be understood that, for those of ordinary skills, can be improved according to the above description or conversion, and all these improvement and conversion all should belong to the protection domain of the utility model claims.
Claims (1)
