Abstract

The invention discloses a dual-purpose pin for floating and lifting, and relates to a pin used for a stamping die. The pin comprises a cylinder, wherein one end of the cylinder is provided with a clamping joint; the clamping joint protrudes out of the cylinder and forms a boss; the other end of the cylinder, far away from the clamping joint, is provided with a clamping groove; the clamping groove and the boss are arranged on the cylinder surface at one end of the cylinder; and the cylinder surface at the other end of the cylinder, opposite to the clamping groove and the boss, is provided with a positioning surface. The pin has the beneficial effects that the cylinder is provided with a positioning surface, the rotation of the pin is avoided in the stamping process, the clamping groove and the boss on the cylinder achieve the positioning effect, and the floating and lifting of a plate-releasing inlet block is realized in conjunction with a spring.

Description

The dual-purpose pin of buoyance lift
Technical field
The present invention relates to the used pin of a kind of press tool.
Background technique
Take off plate in the patrix of press tool and take off plate and go into piece and adopt pin to be connected, be provided with spring in the bottom of pinning, the past pin only plays positioning action, in mould die opening and closing process, can't take into account and take off buoyance lift and the location that plate is gone into piece.
Summary of the invention
The present invention provides a kind of buoyance lift dual-purpose pin, positioning action when it not only plays mold closing, and with spring action effectively control take off the buoyance lift that plate is gone into piece.
In order to achieve the above object, the technological scheme of the present invention's employing is:
The dual-purpose pin of a kind of buoyance lift; Comprise cylinder; It is characterized in that: said cylinder one end is provided with the clamping head, and clamping head protrusion cylinder forms boss, is provided with draw-in groove away from a clamping the other end cylinder; Said draw-in groove and boss are provided with locating face on the cylinder of the relative the other end cylinder with boss of draw-in groove on the cylinder of cylinder one end.
The invention has the beneficial effects as follows that the present invention is provided with locating face on cylindrical body, avoid pin rotation in stamping process, to occur, draw-in groove and the boss that which is provided with have been realized positioning action, realize taking off the buoyance lift that plate is gone into piece with spring action simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the plan view of Fig. 1 of the present invention.
Among the figure: 1. cylinder; 2. clamping head; 3. draw-in groove; 4. boss; 5. locating face.
Embodiment
Through embodiment the present invention is further specified below.
Can know with Fig. 2 by accompanying drawing 1; The present invention includes cylinder 1; Said cylinder 1 one ends are provided with clamping 2, and clamping 2 a protrusion cylinder form boss 4, are provided with draw-in groove 3 away from clamping 2 the other end cylinder 1; Said draw-in groove 3 and boss 4 are provided with locating face 5 on the cylinder of draw-in groove 3 and boss 4 relative the other end cylinders 1 on the cylinder of cylinder 1 one ends.
During use, the present invention is fixed on and takes off plate and take off plate and go between the piece, is provided with spring in clamping 2 bottom, during the punching press mold closing, and length of spring compressed, indentation of the present invention.During die sinking, spring outwards acts on, and the present invention outwards ejects, and realizes the location through boss 4 and locating face 5 simultaneously.
Should be noted that mode of execution of the present invention only is to realize optimal way of the present invention, to belonging to general idea of the present invention, and only is conspicuous change, all should belong within protection scope of the present invention.
