Abstract

A jacking-up device of a jacking-up block on a drawing male die is characterized by comprising a jacking-up block body, an air cylinder, a guiding component, a magnet and a limit pin; the air cylinder is connected to the lower end of the jacking-up block body; a guide post part of the guiding part and the magnet are mounted in the jacking-up block body respectively; a guide sleeve part of the guiding part is mounted in the jacking-up block body; the air cylinder is mounted in a mold body. The jacking-up device has the advantages as follows: 1, compared with a traditional structure jacked on a blank holder, the jacking-up device avoids the shaking trend of the jacking-up block in the drawing process and lowers the debugging difficulty; 2, the jacking-up block is mounted on a lower die, so that the height of the blank holder can be reduced effectively; 3, the jacking-up block mounted on the lower die can use the guide post for guiding, so that the precision of the die can be increased; 4, the jacking-up block mounted on the lower die can be jacked up by the air cylinder, so that the effect of reducing the jacking-up time can be achieved, and a die structure does not require a prepressing pin.

Description

Hold up piece at the picking-up device drawing on punch

(1) technical field:

The utility model discloses a kind of picking-up device that is applied to drawing die, holds up piece at the picking-up device drawing on punch.

(2) background technology:

Automobile panel manufacturer taking cost into account now, for enhancing productivity, the overwhelming majority is that transfer matic is produced continuously, because the transfer matic punching press frequency is fast, and substantially unattended during work, rely on manipulator to send part, need the feed level of product consistent, this just requires most moulds to need product picking-up device.

(3) summary of the invention:

The purpose of this utility model is by a kind of piece that holds up at the picking-up device drawing on punch, it overcomes existing when drawing product and need to hold up, the picking-up piece of mould blank holder can have with the flow direction of plate the shortcoming of the trend of collecting together, the utility model meets the mould structure that transfer matic mould needs hold up, be a kind of succinct, practical, hold up structure reliably.

The technical solution of the utility model: hold up piece at the picking-up device drawing on punch, it is characterized in that it comprises picking-up block body, cylinder, guiding parts, magnet and limit journey pin, described picking-up block body lower end connects cylinder; The guide pillar part of described guiding parts and magnet are arranged on respectively and hold up in block body; The guide pin bushing of described guiding parts is partly arranged on and holds up in block body; Described cylinder is arranged in die ontology.

Described picking-up block body is placed in die ontology; Described cylinder is arranged in die ontology.

The course of work of the present utility model: mould closure state subiculum is bittiness, and bottom surface contacts with body zero clearance, during work, because cylinder is below holding up piece, cylinder piston motion drives picking-up piece and body guiding to hold up product, and limit journey pin plays the effect of secure side pin.

Operation principle of the present utility model: in a punching course, product moves with blank holder after blank holder lifts, and upper mould body is lifted to certain altitude exhaust hood and starts working, holds up product; Manipulator completes one and transmits after step pitch, cylinder drives picking-up piece to move downward until bottom dead centre, in this process, patrix is started working, and after picking-up piece is lower than blank holder, starts to touch material, and blank holder moves down with patrix until bottom dead centre completes a working cycles.

Superiority of the present utility model: 1 structure holding up on blank holder with tradition is compared, and has avoided holding up the trend of collecting together of piece in drawing process, has reduced the difficulty of debugging; 2, hold up piece and be arranged on the height that can effectively reduce blank holder on counterdie; 3, picking-up piece is arranged on counterdie and can uses guide pillar guiding, increases mould and die accuracy; 4, hold up piece and be arranged on counterdie and can use cylinder to hold up, there is to delay effect the picking-up time, mould structure can not used pre-pad.

(4) accompanying drawing explanation:

Fig. 1 is that picking-up piece described in the utility model is at the structure key diagram that draws the picking-up device on punch

To be picking-up piece described in the utility model drawing picking-up device on punch and be arranged on the fundamental diagram of counterdie to Fig. 2.

(5) specific embodiment:

Embodiment: hold up piece in the picking-up device (see figure 1) of drawing on punch, it is characterized in that it comprises picking-up block body 1, cylinder 2, guiding parts 3, magnet 4 and limit journey pin 5, described picking-up block body 1 lower end connects cylinder 2; The guide pillar part of described guiding parts 3 and magnet 4 are arranged on respectively and hold up in block body 1; The guide pin bushing of described guiding parts 3 is partly arranged on and holds up in block body 1; Described cylinder 2 is arranged in die ontology 6.

Described picking-up block body 1 is placed in die ontology 6; Described cylinder 2 is arranged on (see figure 2) in die ontology 6.
