Abstract
The utility model discloses a plug-in stamping die with a mandril below. The plug-in stamping die with the mandril below comprises a punch pin body which is cylindrical and a lower die, wherein a die cavity of the lower die is stair-stepping, a punch pin fixing sleeve is arranged outside the punch pin body in a sleeve mode, a circular conical surface is arranged at the top end of the punch pin body, the circular conical surface is matched with the inner conical surface of the punch pin fixing sleeve, a puller bolt is arranged above the punch pin body and is threadedly connected with the inner wall of the punch pin fixing sleeve, a movable mandril is arranged below the lower die and is opposite to the die cavity of the lower die, and the lower end of the movable mandril is connected with an air cylinder. In the plug-in stamping die with the mandril below, the puller bolt is arranged at the top end of the punch pin body in a pressed mode, reliability of punch pin installation is good, stamping accuracy of products is high, production efficiency is improved, and the movable mandril is arranged below the lower die, so that workpieces which are processed are easy to take out.
Description
Technical field
The utility model relates to the plug-in type diel, and a kind of below has the plug-in type diel of push rod specifically.
Background technology
Drift also is punch, patrix, formpiston, red needle etc., and drift is that drift is mounted in the metal parts in the diel, is applied to contact with the direct of material, makes material generation deformation, cuts material.Mold and punching head generally adopts high-speed steel and wolfram steel etc. as material, and high-speed steel drift and wolfram steel drift are arranged.Directly contact with material (metal or nonmetal) after the mold and punching head that has been installed in die assembly on the forcing press, make material generation separation or plastic deformation, thereby obtain required part.
The utility model content
The purpose of this utility model provides the plug-in type diel that a kind of below has push rod, the installation good stability of drift, and the punching precision of product is high, has improved production efficiency.
The technical solution of the utility model is as follows:
A kind of below has the plug-in type diel of push rod, include columniform red needle body, counterdie, the die cavity of counterdie is step-like, the red needle body is set with the red needle fixed cover outward: the top of red needle body has taper seat, taper seat cooperates with the conical surface of inboard wall of red needle fixed cover, and there is the puller bolt that is screwed together in red needle fixed cover inwall the top of red needle body; The below of counterdie is equipped with movable push rod, and movable push rod is over against the die cavity position of counterdie.
Described movable push rod lower end is connected to cylinder.
The utility model has the advantage of:
Puller bolt of the present utility model is pressed the top of putting with the red needle body, the installation good stability of drift, and the punching precision of product is high, has improved production efficiency, and movable push rod is installed below counterdie, the convenient workpiece that takes out after processing.
Description of drawings
Fig. 1 is the novel structural representation of this practicality.
The specific embodiment
Referring to accompanying drawing, a kind of below has the plug-in type diel of push rod, include columniform red needle body 1, counterdie 5, the die cavity 6 of counterdie 5 is step-like, be set with red needle fixed cover 2 outside the red needle body 1: the top of red needle body 1 has taper seat 3, taper seat 3 cooperates with the conical surface of inboard wall of red needle fixed cover 2, and there is the puller bolt 4 that is screwed together in red needle fixed cover inwall the top of red needle body 1; The below of counterdie 5 is equipped with movable push rod 7, and movable push rod 7 is over against die cavity 6 positions of counterdie 5; Movable push rod 7 lower ends are connected to cylinder 8.
