Abstract
The utility model discloses a kind of door leaf side channel steel piercing dies for belonging to mechanical processing tool and mould range.The door leaf side channel steel piercing die is made of punch-pin, cavity plate and bottom plate；Its convex mould is screwed with die shank；Cavity plate is fixed on bottom plate, and striker plate is supported in the surface of cavity plate on bottom plate；Punch-pin is coaxially fixed across striker plate with cavity plate.The utility model solves the position error offset that scribing line centering by hand generates, when saving scribing line centering time for being wasted increased precision with punch die mould tooling while being improved production efficiency, reduction production cost and labor intensity.
Description
Technical field
The utility model belongs to mechanical processing tool and mould range, more particularly to a kind of door leaf side channel steel piercing die.
Background technology
Existing door leaf side channel steel mounting hole is carried out on drilling machine, and technique is first scribing line positioning by hand, when punching, first
Spile positioning, then punches；If it is macropore, also score expands several times, and process is relatively more, bothersome, and the error generated is inclined
It moves；If with electric hand drill, error bigger is not easy to ensure processing quality, and high rejection rate, processing technology is complicated, and labor intensity is big, ring
Border is seriously polluted, inefficiency.
Utility model content
The purpose of this utility model is to generate big error deviation for scribing line positioning by hand, punching in the prior art；No
Easily ensure processing quality, high rejection rate, processing technology is complicated, and the big deficiency of labor intensity proposes a kind of door leaf side channel steel punching
Mould；It is characterized in that, the door leaf side channel steel piercing die is made of punch-pin, cavity plate and bottom plate；Its convex mould 2 is inserted into die shank 1
It is screwed in groove；Cavity plate 4 is fixed on bottom plate 5, and striker plate 3 is supported on right over cavity plate 4 on bottom plate；Punch-pin 2 is worn
Striker plate 3 is crossed, it is coaxial fixed with cavity plate 4.
The punch-pin 2, cavity plate 4 are matched with the punch size size of regular shape on door leaf side channel steel.
The punch-pin and cavity plate use the Cr12 alloy tool steels of quenched processing.
Door leaf side channel steel is placed on the cavity plate, positioning plate 6 is used in combination to position, and striker plate 3 pushes down door leaf side channel steel.
The punching of the regular shape is circle, ellipse, triangle, square, rectangle or regular hexagon.
The utility model has the beneficial effects that solving the position error offset that scribing line centering by hand generates, scribing line is saved
The time wasted when centering is increased precision while being improved production efficiency with punch die mould tooling, reduces production cost and labor
Fatigue resistance.
Description of the drawings
Fig. 1 is door leaf side channel steel piercing die structural schematic diagram.
Fig. 2 is the door leaf side channel steel piercing die schematic top plan view after removing punch-pin.
The A-A sectional views that Fig. 3 is.
Specific implementation mode
The utility model proposes a kind of door leaf side channel steel piercing dies；It is explained below in conjunction with the accompanying drawings.
Fig. 1, Fig. 2 show door leaf side channel steel piercing die structural schematic diagram.The door leaf side channel steel piercing die is by punch-pin, recessed
Mould and bottom plate are constituted；Its convex mould 2 is inserted into the groove of die shank 1 and is screwed；Cavity plate 4 is fixed on bottom plate 5, striker plate 3
It is supported on bottom plate right over cavity plate 4；Punch-pin 2 passes through striker plate 3, coaxial fixed with cavity plate 4.Wherein, punch-pin 2, cavity plate 4 with
Punch size size matches on door leaf side channel steel.Punch-pin and cavity plate are made of the Cr12 alloy tool steels of quenched processing.
When work, punching machine uses 250 t hydraulic press, door leaf side channel steel piercing die to be mounted on work surface of punching machine, first
Selection and punch size size, the matched punch-pin 2 of shape and cavity plate 4 on door leaf side channel steel are adjusted to coaxial and fixed；By door
Fan side channel steel 7 is placed on above cavity plate 4, and positioning plate 6 is used in combination to position, and striker plate 3 pushes down door leaf side channel steel（As shown in Figure 2 and Figure 3）；
It adjusts punching machine stroke and carries out punching channel steel hole.
