CN203817139U - Stamping die for sectional bar cut opening - Google Patents

Abstract

The utility model relates to a stamping die for a sectional bar cut opening. The stamping die is used for stamping an opening in a hollow internally-arranged shutter glass medium sectional bar. The stamping die for the sectional bar cut opening comprises a stamping die body and a bottom die. A cutter is arranged on the stamping die body. The cutter face of the cuter is an inclined plane. A discharging table is arranged below the cutter. The cut opening is formed in the position where the discharging table makes contact with the bottom die. The cutter, the discharging table and the cut opening are arranged in an axial symmetry mode. The stamping die for the sectional bar cut opening is simple in structure and can complete the opening cutting operation only by being composed of the stamping die body and the bottom die; the cutter face of the inclined plane is designed, so that shear force is dispersed, and the stamping resistance of a punching machine is reduced; after punching is completed, the discharging table automatically discharges scraps, and time and labor are saved.

Description

The diel of a kind of section bar otch

Technical field

The utility model relates to the diel of a kind of section bar otch, for the die-cut openning of built-in hollow louver glass medium section.

Background technology

In built-in hollow louver glass, upper and lower cover plate, the section bars such as drill flute, according to technique needs, must be at section bar upper punch otch, in order to connection, with the installation of the various accessories of facility, parts.

Traditional blanking die structure is more complicated, and critical piece has hold down gag, blanking units and chip removal device.When starting when die-cut, first by hold down gag, workpiece or section bar to be compressed, in case displacement, then by blanking units, undertaken die-cutly, finally by chip removal device, by die-cut, uselessly let out eliminating, or chip removal by hand.

Utility model content

In order to overcome the shortcoming of prior art, the utility model provides the diel of a kind of section bar otch.

Technical solutions of the utility model are as follows:

The diel of section bar otch, comprises punch die and bed die, and described punch die is provided with cutting knife, the knife face of described cutting knife is inclined-plane, described cutting knife has material platform, and the contact position of described material platform and bed die is otch, and described cutting knife, material platform and otch are axial symmetry setting.

The utility model beneficial effect is: (1) is simple in structure, only punch die and bed die, consists of, and just can complete incision operation; (2) design of the cutting knife face on inclined-plane has disperseed shearing force, has reduced the ram drag of punch press; (3), after die-cut, material platform is taken bits material automatically out of, time saving and energy saving.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the utility model is further illustrated.

Fig. 1 is structural representation of the present utility model.

Wherein: 1, punch die; 2, bed die; 3, cutting knife; 4, otch; 5, material platform; 6, section bar.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail.

Consult Fig. 1, the diel of a kind of section bar otch, comprise punch die 1 and bed die 2, described punch die 1 is provided with cutting knife 3, the knife face of described cutting knife 3 is inclined-plane, described cutting knife 3 has material platform 5, and described material platform 5 is otch 4 with the contact position of bed die 2, and described cutting knife 3, material platform 5 and otch 4 are axial symmetry setting.

The utility model operation principle is that section bar 6 is put into material platform 5, gently push-tight, punch die 1 moves downward, and cutting knife 3 contact section bars 6, form a little openning, punch die 1 continues down motion, due to the cutting knife inclined-plane of cutting knife 3, make section bar 6 have all the time the power being close to punch die 1, and the cutting knife inclined-plane of cutting knife 3 and bed die 2 formation shearing forces, can reduce the die-cut resistance of punch press, when die-cut, complete, punch die 1 moves upward, and by material platform 5, bits material strip is gone out.

Above-mentioned drawings and Examples are only for the utility model is described, any under technical field those of ordinary skill suitable variation or modification that it is done, or use other flower types instead and make this technical change, all should be considered as not departing from the utility model patent category.

Claims (1)

1. section bar otch diel, comprise punch die (1) and bed die (2), it is characterized in that: described punch die (1) is provided with cutting knife (3), the knife face of described cutting knife (3) is inclined-plane, described cutting knife (3) has material platform (5), described material platform (5) is otch (4) with the contact position of bed die (2), and described cutting knife (3), material platform (5) and otch (4) are axial symmetry setting.
