Abstract
The invention relates to an assembling die structure with powder leaking grooves. The assembling die structure with the powder leaking grooves comprises an upper-two-lower-two structure mainly composed of two upper punches and two lower punches, wherein the second upper punch is arranged in the first upper punch and matched with the first upper punch, the second lower punch is connected in the first lower punch in a clamped mode and matched with the first lower punch, a product cavity is formed between the working surface of the second upper punch and the working surface of the second lower punch, a female die is installed on the outer surface of the first lower punch in a matched mode, a female die gland and a female die press pad which are fixed with each other are connected to the outer edge of the shoulder surface of the female die in a clamped mode, and grooves are formed in an effective section, matched with the female die, of the outer surface of the first lower punch in the radial direction. According to the assembling die structure with the powder leaking grooves, the first lower punch is provided with the powder leaking grooves, under the condition that the effective section is not reduced, iron powder existing in a gap between the first lower punch and the female die can be reduced in the process of die releasing, and therefore the die releasing of a product is smooth, and the life of the first lower punch is prolonged.
Description
Technical field
The invention belongs to field of powder metallurgy, be specifically related to a kind of assembling die structure carrying Lou powder groove, for suppressing the powder metallurgy product of the complexity with spline and deep trouth.
Background technology
The effective section of existing powder metallurgy drift is generally continuously equidistant straight section, and be namely parallel to pressing direction completely, in stowing operation, iron powder, due to Action of Gravity Field, does not exist only in die cavity, is present in the gap of drift and former yet; In pressing process, because density requirements is higher, drift compressive deformation swells; In knockout course, easily there is snap gauge, thus cause a large amount of maintenance in production process to scrap.
Because frictional force is large in knockout course, the wearing and tearing to drift can be accelerated, reduce the service life of drift.
Summary of the invention
Inventing problem to be solved is exactly in the assembling die of complexity, when neither reducing effective section, can reduce again powder metallurgy product in shaping knockout course, being deposited in the iron powder in the gap of undershoot and former, avoiding snap gauge.And extend the mold use life-span by optimal design, reduce production cost, solve the destabilizing factor in producing.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
A kind of assembling die structure carrying Lou powder groove, comprise and form upper two times two structures primarily of two upper punches and two undershoots, wherein, second upper punch is arranged in the first upper punch also to be formed and cooperatively interacts, second undershoot is connected in the first undershoot also to be formed and cooperatively interacts, product chamber is formed between the working face of the second upper punch and the second undershoot, the outer surface of the first undershoot coordinates former is installed, described former shoulder face outer rim is connected with the former gland and former pressure pad that fix, and effective section that described first undershoot outer surface coordinates with former is radially provided with groove.
Further, the groove on described first undershoot outer surface is communicated with face of cooling down.
Further, the fineness of described first undershoot outer surface and inner surface is within Ra0.04.
Further, the shaft shoulder place of described first upper punch is connected with stamping cover on first, the outer rim of the second upper punch is provided with multiple first upper punch pressure pad, and on the first upper punch pressure pad and first, stamping cover is abutted against, and the shaft shoulder place of the second upper punch and rear end face place are respectively arranged with stamping cover and the second upper punch pressure pad on second.
Further, the shaft shoulder place of described first undershoot is connected with first time stamping cover, extend cooperation in the first undershoot section in the second undershoot and the first undershoot pressure pad is installed, first undershoot pressure pad and first time stamping cover are abutted against, and the shaft shoulder of described second undershoot and corresponding end-faces place are respectively arranged with second time stamping cover and the second undershoot pressure pad.
The invention has the beneficial effects as follows:
1, after adopting first time punching forming of the present invention, pressed compact effectively can be prevented to be shaped in the compacting demoulding and to produce snap gauge phenomenon, obviously reduce the quality risk of pressed compact in forming process.
2, by producing checking, the first undershoot life-span of this invention is adopted to be enhanced about more than once than before.
