Abstract
The utility model relates to auto parts and components field, particularly drawing die, comprises punch and die and holding pad, described die comprises core rod and die holder, core rod is placed in the cavity of die holder, and be provided with cushion block between at the bottom of the bottom of core rod and the chamber of cavity, this cushion block is fixed on core rod or die holder.Owing to adopting above technical scheme, adjustment height of cushion block between core rod and die holder just equals the relative altitude that have adjusted die core rod forming surface and holding pad, thus realize the drawing depth of adjustment mould, only need cushion block to disassemble and carry out replacing thickness and just can realize this object, adjustment is got up very convenient, saving of work and time, efficiency is high.
Description
Technical field
The utility model relates to auto parts and components field, particularly drawing die.
Background technology
The outer covering piece of automobile adopts drawing operation to make, and drawing operation is the flow harden characteristic that make use of steel, and so-called flow harden characteristic refers to that metal is in cold conditions plastic deformation, makes the strengthening index of metal, as the raising such as yield point, hardness.At normal temperatures, remove external force after steel being stretched to strain, steel are after this processing, the length of steel increases, reduced, and elastic limit rises to and is equivalent to raw material strain, greatly improve elastic limit of materials, and strain rate is reduced, improve the rigidity of material.If but less the causing of steel stretch range is not stretched to strain and has just removed external force, the intensity of steel can be caused not enough.The hair net outside plate of such as automobile, the part such as luggage-boot lid outside plate and top cover, because its Curvature varying is less, shape is comparatively mild, and moulding is simple, and deformation extent is very little, that is stretch range is little, just be easy to cause part rigidity not enough, under natural storage state, have the defect stayed, very easily produce distortion, product quality is poor, just needs to adjust drawing depth.
Traditional drawing die is integral type structure, and its binder surface and shaping profile are a foundry goods.If mould finds that after developing the rigidity of part is not enough, usually take adjustment blank holder pressure, optimize periphery addendum, adjustment draw-bead structure or research the measures such as profile laminating rate to improve.The time that these measures spend is long, costly, to die ontology injury comparatively greatly, the rigidity of part may effectively not improved or be not improved simultaneously.
Summary of the invention
It is abundant that the purpose of this utility model is to provide a kind of drawing, drawing die easy to adjust
For achieving the above object, the utility model have employed following technical scheme: a kind of drawing die, comprise punch and die and holding pad, described die comprises core rod and die holder, core rod is placed in the cavity of die holder, be provided with cushion block between at the bottom of the bottom of core rod and the chamber of cavity, this cushion block is fixed on core rod or die holder.
Owing to adopting above technical scheme, adjustment height of cushion block between core rod and die holder just equals the relative altitude that have adjusted die core rod forming surface and holding pad, thus realize the drawing depth of adjustment mould, only need cushion block to disassemble and carry out replacing thickness and just can realize this object, adjustment is got up very convenient, saving of work and time, efficiency is high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
The structural representation of core rod during Fig. 2;
Fig. 3 is the structural representation of die holder.
Detailed description of the invention
As Figure 1-3, a kind of drawing die, comprise punch 10 and die 20 and holding pad, described die 20 comprises core rod 21 and die holder 22, core rod 21 is placed in the cavity 221 of die holder 22, be provided with cushion block 23 between at the bottom of the bottom of core rod 21 and the chamber of cavity 221, this cushion block 23 is fixed on core rod 21 or die holder 22.
Die 20 is divided into core rod 21 and die holder 22 two parts, processing is got up also very convenient.Adjustment height of cushion block 23 between core rod 21 and die holder 22 just equals the height that have adjusted core rod 21, so core rod 21 forming surface and and the relative altitude of holding pad 23 also just obtain adjustment, thus realize the drawing depth of adjustment mould.When finding that part rigidity is not enough, only need cushion block 23 to disassemble to process, or directly changing cushion block 23 just can realize increasing stretching depth, adjustment is got up very convenient, and saving of work and time, efficiency is high.
Described cushion block 23 is provided with two or more and is evenly spacedly distributed in cavity 221.In order to alleviate mold weight, save production cost, core rod 21 is not solid construction, is reinforcements that interval arranges outwardly convex in the bottom of core rod 21, the utility model be exactly at the bottom of the chamber of reinforcement and cavity 221 between cushion block 23 is set, each reinforcement correspondence arranges a cushion block.
In the bottom that described cushion block 23 is fixed on cavity 221 and both adopt screw to connect, the surrounding sidewall of described core rod 21 is equipped with slide plate 211, and this slide plate 211 abuts on the sidewall of cavity 221.The thickness of adjustment slide plate 211 can adjust the position of core rod 21 in cavity 221, be detachable connection between slide plate 211 and core rod 21 in the utility model, if slide plate 211 has wearing and tearing after using for a long time, can directly by replacing slide plate 211, ensure the stability of core rod 21, also save production cost.
On the sidewall of described cavity 221, the position corresponding with slide plate 211 is provided with the flange 222 that leads, and slide plate 211 abuts on the plate face of guiding flange 222.When core rod 21 loads die holder 22, slide plate 211 is along guiding flange 222 slide downward, guiding flange 222 makes core rod 21 form discontinuity with die holder 22 contact, is also convenient to the taking-up from die holder 22 of core rod 21 while ensureing the reliable and stable loading die holder 22 of core rod 21.Slide plate 211 and guiding flange 222 can adopt high-abrasive material to make.
