A kind of diel of fine-tuning mold and punching head
Technical field
The present invention relates to a kind of diels of fine-tuning mold and punching head, belong to Stamping Die Technology field.
Background technology
Diel is in Cold Press Working, by material(Metal is nonmetallic)It is processed into a kind of special work of part
Skill is equipped, referred to as cold punching die(It is commonly called as cold-punching mould).Punching press is at room temperature, to utilize the mold pair on forcing press
Material applies pressure, it is made to generate separation or plastic deformation, thus a kind of pressure processing method of part needed for obtaining.For shape
The more complicated product of shape generally requires to carry out lateral punching to a certain position of product or certain positions, is molded side core-pulling;
And the mechanism of lateral punching processing is completed, it mainly drives by drive block and is realized into sub- lateral movement, in shrapnel and Terminals Die
In tool, because of the unstability of angle rebound, it is often necessary to the stringenter product of shaping, especially angle requirement.
In shaping, the conventional practice is fixed using punch, and shaping surface is the Training system of plane.This kind of Training system
Under, due to the influence of the factors such as material thickness deviation, mold manufacturing error and forming technology, tends to punch occur and enter son
Stuck situation needs to dismantle template at this time, then repaiies punch, if once adjusted bad it is necessary to multiple form removal, mode transfer time
Several times will be increased, in production, since angle caused by the hardness of material and the deviation of thickness is overproof, form removal again adjusts,
Workload is considerably increased, and then causes to be delayed manufacturing schedule.For this reason, it may be necessary to design a kind of new technical solution, can integrate
Overcome above-mentioned the deficiencies in the prior art to property.

Drive rod;
The lower die holder is arranged above lower mold, is provided with what the cooperation mold and punching head used on the lower mold
Forming cavity.
As an improvement of the above technical solution, the lastics dress being used cooperatively is provided with positioned at the mold and punching head centre
It sets, the connecting rod of the upper die holder is provided through on the lastics device.
As an improvement of the above technical solution, the lower mold includes pedestal, and the pedestal both ends are symmetrically arranged with lower die
Block is both provided with internal module, the top turning of the lower module and the internal module on the opposite madial wall of two lower modules
Place is both provided with pulley, and the forming cavity adjustable plate being used cooperatively, forming cavity adjustable plate bottom end are provided on two pulleys
Face is provided with the sliding slot and sliding rail for coordinating the pulley to use, and the lower module top is both provided with the cooperation forming cavity and adjusts
The bindiny mechanism that plate uses.
As an improvement of the above technical solution, cold flow system makes are additionally provided in the lower mold, the cold flow system makes include
Cold runner, the cold runner pass through two lower modules, the internal module and pedestal setting, and in the lower module side wall
On be provided with the cold flow interface being connected with the cold runner.
The type of cooling of cold flow system makes of the present invention is one kind in cold airflow or salt bath.
Compared with prior art, implementation result of the invention is as follows by the present invention:
A kind of diel of fine-tuning mold and punching head of the present invention, improves mold in the prior art and is unable to adjust
The technical issues of, the adaptability of mold is improved, the processing quality and production efficiency of mold are improved, meets actual use and wants
It asks.
