The utility model discloses a kind of main mould positioning block structures, including spacer pad and main mould red needle, the spacer pad is cylinder, its two bottom center is provided with a central through hole, the main mould red needle is inserted into the central through hole, the central through hole diameter is adapted to the main mould red needle diameter, a side opening for extending to the central through hole is provided on the side of the spacer pad, a top stick is provided in the side opening, main mould red needle side is provided with a groove along its length, is provided with linear type or abnormal-shaped punch on an end face of the main mould red needle.Pass through a kind of main mould positioning block structure provided by the utility model, it can complete the functions such as positioning in punching press irregularly-shaped hole to hole site, the control for the needle stroke that liquidates, and due to the effect of side opening top stick, red needle will not keep punching course safer in punching course there is a phenomenon where popping up.
Description
Technical field
The utility model relates to field of machining, and in particular to a kind of main mould positioning block structure.
Background technique
Punching press is that depended on pressure machine and mold apply external force to plate, tubing and profile etc., is allowed to generate plastic deformation or divide
From thus the forming and machining method of the workpiece of shape and size needed for obtaining.
In punching parts, it is often necessary to stamp out a word hole or irregularly-shaped hole, mainly relies on be positioned manually at this stage, nothing
Method meet this pores set in place and depth in terms of required precision.
Summary of the invention
In order to solve the above-mentioned technical problem, the utility model provides a kind of main mould positioning block structure, can guarantee to rush
To the requirement in terms of position and depth when pressing a word hole or irregularly-shaped hole.
The technology employed by the present utility model is
A kind of main mould positioning block structure, including spacer pad and main mould red needle, the spacer pad are cylinder, two bottoms
Face is provided centrally with a central through hole, and the main mould red needle is inserted into the central through hole, and the central through hole diameter is adapted to institute
Main mould red needle diameter is stated, a side opening for extending to the central through hole, the side opening are provided on the side of the spacer pad
In be provided with a top stick, main mould red needle side is provided with one along its length and is not extend to the groove at both ends, described
Linear type or abnormal-shaped punch are provided on one end face of main mould red needle.
Preferably, the width of the groove of the main mould red needle is adapted to the diameter of the top stick.
Preferably, the length of the groove of the main mould red needle is equal to the path increment and the spacer pad of the main mould red needle
The sum of side opening diameter.
Preferably, the side opening is located at the spacer pad center, and the 1/2 of a diameter of spacer pad thickness.
Preferably, when the diameter of the main mould red needle is 0~10mm, the depth of the groove is 1mm.
Preferably, when the diameter of the main mould red needle is 10~30mm, the depth of the groove is 2mm.
Preferably, the chamfer angle of the recess edge is not less than 20 °, and otherwise the main mould positioning block structure will lose fixed
Position effect.
It is further preferred that the chamfer angle of the recess edge is not more than 45 °, speed is otherwise worn in chamfering active procedure
Degree is accelerated, and the service life of red needle will reduce.
The beneficial effects of the utility model are: by a kind of main mould positioning block structure provided by the utility model, it can be complete
At in punching press irregularly-shaped hole to functions such as the controls of the positioning of hole site, the needle stroke that liquidates, and due to the effect of side opening top stick, punching
Needle will not keep punching course safer in punching course there is a phenomenon where popping up.
