Description
Technical field
The utility model relates to the Precision Forming Technology of part.Relate to a kind of device for discharging that moves back specifically, when being applicable to introversion Noodles parts such as producing cold, warm, hot precision plastic forming internal spline, internal gear, endoporus in batches, moving back of the mandrel that contains in its part or the blank or mould unloaded.
Background technology
At present, when introversion Noodles parts (blank) such as cold, warm, hot precision plastic forming internal spline, internal gear, endoporus, the reason that is subjected to forming technology, technical limitations now all adopts and increases by a procedure and move back and unload mandrel (mould).Namely behind the main forming of finishing introversion Noodles parts (blank) such as internal spline, internal gear, endoporus, contain mandrel or mould in the shaping semi-products, need increase by a procedure again moves back specially and unloads mandrel or mould, also need change manufacture specially move back the discharging mould, and because this processing and manufacturing of moving back the discharging mould of needs of the relation of matching bothers relatively, need to take again press apparatus simultaneously, so just make the press live load increase, not only time-consuming but also effort, production efficiency is not high and waste energy.
Summary of the invention
The purpose of this utility model provides a kind of device for discharging that moves back at existing weak point in the above-mentioned prior art just.Device of the present utility model can be installed in the non-groundwork of press position, realizes the mandrel in the part semi-products or mould are withdrawed from the press operate as normal.Also namely utilize the complementary energy of equipment, once two procedures are finished in action, can reduce power consumption, reduce machine utilization, enhance productivity.
The purpose of this utility model can realize by following technique measures:
The device for discharging that moves back of the present utility model is made of upper punch and following stationary magazine creel two parts; Wherein, Described punch branch comprises the connecting plate that is sleeved on successively together and carries out spacing drift, drift adapter sleeve and nested structure by the inner and outer ring platform that cooperatively interacts; Described stationary magazine creel down partly comprises the mould tube, be installed in the retainer ring in the mould tube lower cavity, be arranged in the ring that withdraws from of retainer ring inner chamber body, be installed in the mould tube upper chamber and be positioned at the element mounting (blank seat) of sleeved structure that is used for placing part or blank and mandrel or set of molds zoarium of retainer ring upper end; Described drift is arranged on mandrel or mould top in the mode with mandrel or mould coaxial line.
The upper mouth of element mounting described in the utility model (blank seat) is the back taper loop configuration; The described device for discharging that moves back is installed in the mould bases up and down of press or the outside, groundwork position (the non-groundwork of press position) of template.
Operation using method of the present utility model may further comprise the steps: upper punch, and---following stationary magazine creel------------mandrel (mould) moves back and unloads, and corresponding centering is finished and is moved back discharging in press work to place part (blank) by---part (blank) removes---.More specifically:
A, processing upper punch, part (blank) seat, move back parts such as unloading ring;
B, fit on drift, following stationary magazine creel;
C, upper punch is fastened on top mold frame or the template, will descends stationary magazine creel to be fastened on down on mould bases or the template;
D, with upper punch, down stationary magazine creel is adjusted to center line centering up and down;
E, part (blank) is placed in part (blank) seat:
F, along with the normal descending action of press drives the descending pushing mandrel of upper punch (mould);
G, attend by the descending of press, upper punch pushing mandrel (mould) is deviate to it:
H, part (blank) is removed, finish and move back the discharging action.
It should be noted that: described fit on drift, following stationary magazine creel are according to geomery processing upper punch and the blank seat (element mounting) that will move back the mandrel (mould) that unloads; In actual applications, no matter mandrel (mould) size shape how, upper punch all can be made symmetrical circular, and upper punch can need not change (usually) substantially and only needs the renewal part seat to get final product.And described move back device for discharging when being applicable to Plastic Forming introversion Noodles part in batches moving back of its mandrel (mould) unload, and this method is the complementary energy when utilizing press main forming part, is once to move to finish two procedures, kills two birds with one stone.
The beneficial effects of the utility model are as follows:
1, apparatus structure is simple, and required precision is not high, and processing and manufacturing is easy;
2, press apparatus complementary energy recycling belongs to green manufacturing;
3, reduce manufacturing procedure, kill two birds with one stone, enhance productivity;
4, this device is applicable to that its semi-products contain moving back of mandrel or mould after the Plastic Forming of producing introversion Noodles part in batches and unloads versatility, practicality, strong operability.

The specific embodiment
The utility model is further described below in conjunction with embodiment (accompanying drawing):
As shown in Figure 1, the described device of device for discharging that moves back of the present utility model is made of the non-groundwork of press position upper punch and following stationary magazine creel two parts; Wherein, Described punch branch comprises the connecting plate (3) of the drift (1), drift adapter sleeve (2) and the nested structure that are sleeved on successively together and cooperatively interact; Described stationary magazine creel down partly comprises mould tube (9), be installed in the retainer ring (8) in mould tube (9) lower cavity, what be arranged in retainer ring (8) inner chamber body withdraws from ring (7), is installed in mould tube (9) upper chamber and is positioned at the element mounting (6) that is used for placing part or blank (4) and the sleeved structure of mandrel or mould (5) assembly of retainer ring (8) upper end; Described drift (1) is arranged on mandrel or mould (5) top in the mode with mandrel or mould (5) coaxial line.
For the part that makes various ways or blank (4) thus can remove easily and finish in the manufactured part mandrel or moving back of mould (5) unloaded, the utility model is designed to the back taper loop configuration with the upper mouth of described element mounting (blank seat) (6).
Device of the present utility model can be installed in the non-groundwork of press position---and be that the described device for discharging that moves back is installed in the mould bases up and down of press or the outside, groundwork position of template.Its objective is and in the press operate as normal, realize the mandrel in the part semi-products or mould are withdrawed from.Also namely utilize the complementary energy of equipment, once two procedures are finished in action, can reduce power consumption, reduce machine utilization, enhance productivity.
The concrete assembling mode that moves back device for discharging of the present utility model is as follows:
With drift adapter sleeve (2) and connecting plate (3) interference fit, then drift (1) is put into its hole earlier, partly use bolted on top mold frame or press template the upper punch that assembles; Withdrawing from the mould tube (9) of packing into after ring (7) and retainer ring (8) cooperate, element mounting (blank seat) (6) is pressed into forms stationary magazine creel part down in the mould tube (9) then.Following stationary magazine creel partly is fixed by bolts to down mould bases or press template and upper punch correspondence position.So, this moves back device for discharging and just can begin along with press main forming action auxiliaryly to have moved back discharging work, and then realizes in the Plastic Forming introversion Noodles part semi-products that mandrel or moving back of mould unload.
