Abstract

The utility model discloses a die for downward drawing procession of a thin-material work piece. The die comprises an upper die plate, a concave die, a lower die plate, an ejection pressing spring, a pressure plate, a plunger chip, an ejection block, stripping springs and a striking plate, wherein the pressure plate is installed on the upper die plate through cooperation of the ejection pressing spring and a guide post; the plunger chip is fixedly installed on the upper die plate; the concave die is installed on the lower die plate; the plunger chip is matched with a cavity of the concave die; the striking plate is installed below the lower die plate; the lower surface of the striking plate is connected and matched with a plurality of stripping springs; the ejection block is fixedly installed on the striking plate; the ejection block is inserted into the cavity of the concave die; the striking plate is connected with the upper die plate through a plurality of limiting posts. When the die for downward drawing procession of the thin-material work piece disclosed by the utility model works, because of existence of the limiting posts, linkage of the upper die plate and the striking plate can be realized, alternative contact of the plunger chip and the ejection block with the thin-material work piece can be realized, the thin-material work piece bears a small force and is hard to deform.

Description

Mould for the downward stretch process of thin materials and parts
Technical field
The utility model relates to a kind of diel, specifically a kind of mould for the downward stretch process of thin materials and parts.
Background technology
Numerous parts product, because of the consideration of the factors such as use or Structural Design Requirement, usually has the structure of downward stretching indent.In order to process class formation, be generally to use punch press and mould to coordinate, carry out punching stretch.The mould structure of existing stretching and punching is similar, and its basic principle is to compress material by the holding pad on mould, then uses drift to coordinate counterdie shape chamber to carry out punching stretch processing.The structure of this kind of mould is comparatively simple, uses reliably, be widely adopted, but in actual use, mould also needs to consider the problem of de-material, and the product after machining is separated with drift and mould, so that take off.This type of present mould has deficiency on de-material, specifically, its de-material of present mould is to utilize the jacking block of establishing in holding pad and counterdie to coordinate, drift rollback above pushes away and synchronizes with jacking block, take off material, product is when de-material, can be subject to the internal resistance frictional force of drift and separation of products and the upward pressure of jacking block simultaneously, when as poor in product structure intensity, can cause product distortion to a certain degree, thin materials and parts particularly, its distortion is more obvious, makes the thin materials and parts that drawn processes not meet product design structural requirement.
Utility model content
The purpose of this utility model is to provide a kind of a kind of mould that can reduce pressure suffered in the de-material process of thin materials and parts after stretch process completes.
For achieving the above object, the technical scheme that the utility model adopts is:
For a mould for the downward stretch process of thin materials and parts, it includes cope match-plate pattern, die, lower bolster, top pressure spring, holding pad, drift, jacking block, de-material spring and re-packs.
The logical top pressure spring of holding pad and guide pillar cooperation are arranged on cope match-plate pattern;
Drift is packed on cope match-plate pattern;
Die is arranged on lower bolster;
Described drift coordinates with the shape chamber of die;
Re-pack and be arranged under lower bolster, its lower surface is connected cooperation with a plurality of de-material springs;
Described jacking block is packed in and re-packs above, and described jacking block inserts in the shape chamber of die;
Described re-pack with cope match-plate pattern between by many limited posts, be connected.
The utility model when work, because of spacing existence of living, can realize cope match-plate pattern and re-pack interlock, can realize drift and alternately contact with thin materials and parts with jacking block, thin materials and parts are stressed less, not yielding.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
For convenience of the utility model is understood, existing in conjunction with Fig. 1 for an embodiment, the utility model is made to further explanation.
Embodiment:
As shown in Figure 1, the utility model includes cope match-plate pattern 1, die 2, lower bolster 3, top pressure spring 4, holding pad 5, drift 6, jacking block 7, de-material spring 8 and re-packs 9.The logical top pressure spring 4 of holding pad 5 and guide pillar cooperation are arranged on cope match-plate pattern 1; Drift 6 is packed on cope match-plate pattern 1; Die 2 is arranged on lower bolster 3; Described drift 6 coordinates with the shape chamber of die 2; Re-packing 9 is arranged on lower bolster 6 times, and its lower surface is connected cooperation with a plurality of de-material springs 8; Described jacking block 7 is packed in and re-packs on 9, and described jacking block 7 inserts in the shape chamber of dies 2; Described re-packing 7 is connected by many limited posts 10 with 1 of cope match-plate pattern.
