Abstract
The utility model relates to a female die structure capable of preventing waste rebound. The female die structure comprises a female die provided with a through groove in the middle. An inverted cone frustum structure is formed on the upper portion of the through groove. A cone frustum structure is formed on the lower portion of the through groove and at the bottom of the inverted cone frustum structure by means of extension. The female die structure further comprises wastes generated during machining. The wastes clamped in the inverted cone frustum structure fall into the cone frustum structure and enter a waste groove. The female die structure is simple in structure, convenient to manufacture and operate, low in cost, and suitable for hard material punching, and waste rebound can be prevented effectively during die punching.
Description
Technical field
The utility model relates to die device, especially a kind of die structure of anti-waste material rebound.
Background technology
Stamping-out is a kind of stamping procedure that utilizes punch die that part material or operation part are separated with another part material, worker's (order) part or waste material.
In actual process, the problem that waste material rebound will inevitably run into when being present punch process, phenomenons such as product is bad, mould damage that it easily causes.The main cause that causes the waste material rebound has the absorption of vacuum generation, the absorption at punch cutting edge place, the absorption that fluid produces, the magnetic force of punch, the negative pressure that die compressed air causes etc.In order to prevent the waste material rebound, often adopt the method for liftout punch, band pore punch or increase die inner surface roughness.The effect of these methods is all little, and the phenomenon of waste material rebound does not improve.
The utility model content
The applicant is at the shortcoming that easily produces the waste material rebound phenomenon in the above-mentioned existing production technology; the die structure that provides a kind of anti-waste material rational in infrastructure to knock-on; thereby prevented that effectively waste material from the phenomenon of rebound taking place; protection die upper surface; when carrying out punching press next time; can not damage die upper surface or damage band material, prolong the service life of die.
The technical scheme that the utility model adopts is as follows:
A kind of die structure of anti-waste material rebound comprises die, and described die middle part has the break-through groove, and described break-through groove top becomes the reverse frustoconic structure, and described break-through groove bottom also is positioned at the reverse frustoconic structural base and extends into the truncated cone-shaped structure; Also comprise the waste material that produces in the process, described waste material is stuck in in the reverse frustoconic structure, enters reject chute in falling the truncated cone-shaped structure again.
As further improvement in the technical proposal:
The diameter a of described reverse frustoconic structure end face is 6.06mm, and the diameter b of described reverse frustoconic structure bottom surface is 6.00mm;
The diameter of described truncated cone-shaped structure end face is identical with the diameter of reverse frustoconic structure bottom surface;
The diameter of described waste material is identical with the diameter of reverse frustoconic structure end face.
The beneficial effects of the utility model are as follows:
The utility model is simple in structure, and is easy to make, easy to operate, and cost is low, can effectively prevent the phenomenon of waste material rebound in the mould stamping-out process, and the utility model is also applicable to hard occasion of expecting stamping-out.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Wherein: 1, die; 2, reverse frustoconic structure; 3, waste material; 4, truncated cone-shaped structure.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.
As shown in Figure 1, the die structure of the anti-waste material of present embodiment rebound comprises die 1, and die 1 middle part has the break-through groove, and break-through groove top becomes reverse frustoconic structure 2, and break-through groove bottom also is positioned at reverse frustoconic structure 2 bottoms and extends into truncated cone-shaped structure 4; Also comprise the waste material 3 that produces in the process, waste material 3 is stuck in in the reverse frustoconic structure 2, enters reject chute in falling truncated cone-shaped structure 4 again.
The diameter a of reverse frustoconic structure 2 end faces described in the utility model is 6.06mm, and the diameter b of reverse frustoconic structure 2 bottom surfaces is 6.00mm.
The diameter of truncated cone-shaped structure 4 end faces is identical with the diameter of reverse frustoconic structure 2 bottom surfaces, and namely the diameter of truncated cone-shaped structure 4 end faces is 6.00mm.
The diameter of waste material 3 is identical with the diameter of reverse frustoconic structure 2 end faces, and namely the diameter of waste material 3 is 6.06mm.
In the actual use, when punch (not drawing among the figure) stamping-out produces waste material, punch (not drawing among the figure) withstands in the reverse frustoconic structure 2 that waste material 3 at first enters die 1, because die 1 reverse frustoconic structure 2 is 0.06mm with the size section difference of truncated cone-shaped structure, this moment, waste material 3 was mobile from top to bottom under the effect of punch (not drawing among the figure), because more and more littler in reverse frustoconic structure 2 inside dimensions, frictional force increases, waste material 3 just is stuck among the die 1 firmly like this.Effectively reduced the rebound of die 1 waste material 3; Through continuous stamping-out, after the waste material 3 of Chan Shenging passed through before, the waste material 3 accumulation back extruding of follow-up generation were dropped downwards, enter reject chute until breaking away from die 1.
The utility model is circular and various abnormally-structured products applicable to easily producing waste material 3, and versatility is extensive, and cost is low.
More than describing is to explanation of the present utility model, is not the restriction to utility model, and the utility model institute restricted portion within protection domain of the present utility model, can be done any type of modification referring to claim.
