Abstract
The utility model discloses a kind of deep-draw part bulging processing mold, comprise a die, be arranged on the binder drift above die and the de-feed ring be placed in die and forming punching head, described de-feed ring is socketed on forming punching head and the two can move up and down by relatively independent carrying out, the top of described forming punching head is provided with a projection, described projection diameter is less than forming punching head lower end diameter, and before described projection diameter and bulging, diameter of part to be processed is suitable.By the bulging processing of using this device effectively can complete the inwardly protruded deep-draw part of oppose side wall.Be different from the sidewall convex feature that tradition processing needs to be completed by rolling process part, use this device both can complete convenient stable large-scale industrial production, it also avoid slide block structure in tradition processing and, to the damage of part outer wall, further increase the quality of product.
Description
Technical field
The utility model relates to a kind of deep-draw part bulging processing mold, is particularly useful for the bulging processing of the inwardly protruded deep-draw part of partial sidewall, belongs to machine components manufacture field.
Background technology
In recent years, the demand of deep-draw part is increasing.It is cylindric that product design is also not only confined to straight wall, and the groove on the wall of image side, projection etc. feature, constantly challenges the process of manufacturing process.Such part generally uses conveying type mould to produce, and part is relatively free in mould, can shaping more complicated shape.But still existence part part as shown in Figure 2 cannot use existing transmission lathe to produce due to many reasons such as size is large, operation is many, the use limitation of machining tool.And this kind of feature side-wall inwardly protruding, feature more complicated, need to apply to rolling process to operate, and in continuous mould, part cannot rotate in existing processing method; If use slide block structure, part outer wall can be made again to produce cut.This causes a no small difficult problem just to the large-scale industrial production of enterprise.
Summary of the invention
In view of the defect that above-mentioned prior art exists, the purpose of this utility model proposes a kind of deep-draw part bulging processing mold.
The purpose of this utility model, will be achieved by the following technical programs:
A kind of deep-draw part bulging processing mold, comprise a die, be arranged on the binder drift above die and the de-feed ring be placed in die and forming punching head, described de-feed ring is socketed on forming punching head and the two can move up and down by relatively independent carrying out, the top of described forming punching head is provided with a projection, described projection diameter is less than forming punching head lower end diameter, and before described projection diameter and bulging, diameter of part to be processed is suitable.
Preferably, after described concave die cavity diameter and part bulging to be processed, external diameter is suitable.
Preferably, described de-feed ring external diameter is identical with the die cavity internal diameter of described die.
Preferably, described forming punching head is protruding is formed with an indent R angle with junction, forming punching head lower end.
Preferably, the radian of the indent radian at described R angle and the sidewall convex needed for part to be processed matches.
Preferably, the radian of the indent radian at described R angle and the sidewall convex needed for part to be processed matches.
Preferably, the processing method of described deep-draw part bulging processing mold, comprises the steps:
(1) binder step, binder drift promotes part to be processed and enters in the middle die cavity of die, and is pressed abd fixed in die by part to be processed;
(2) bulging step, after compression, forming punching head moves upward, and described forming punching head enters into the inside of part to be processed, completes the bulging punching press treating processing parts;
(3) de-material step, after the bulging of part to be processed completes, forming punching head resets downwards, and binder drift lifts upward simultaneously, and subsequently, de-feed ring moves upward, and the part completing bulging is ejected die;
(4) reset process, after the part after bulging completes is ejected die, de-feed ring resets downwards, and after described reseting procedure completes, binder drift promotes next part to be processed immediately and enters die.
The utility model gives prominence to effect: by the bulging processing of using this device effectively can complete the inwardly protruded deep-draw part of oppose side wall.Be different from the sidewall convex feature that tradition processing needs to be completed by rolling process part, use this device both can complete convenient stable large-scale industrial production, it also avoid slide block structure in tradition processing and, to the damage of part outer wall, further increase the quality of product.
Below just accompanying drawing in conjunction with the embodiments, is described in further detail detailed description of the invention of the present utility model, is easier to understand, grasp to make technical solutions of the utility model.
Accompanying drawing explanation
Fig. 1 is the structural representation of this device.
Fig. 2 is product structure schematic diagram.
Detailed description of the invention
As shown in Figure 1, the utility model discloses a kind of deep-draw part bulging processing mold, bulging for deep-draw part is processed, and comprise die 2, be arranged on the binder drift 3 above die and be placed in de-feed ring 1 and the forming punching head 4 of die inside, described de-feed ring 1 is sheathed on forming punching head 4.
The die cavity diameter of described die 2 is equal with the external diameter after part 5 bulging to be processed.
Described binder drift 3 is arranged on above die 2, and binder drift 3 lower end is connected to the top of part 5 to be processed, plays the effect of compacting part.
Described de-feed ring 1 is socketed on described forming punching head 4 and the two can move up and down by relatively independent carrying out.Described de-feed ring 1 external diameter is identical with the die cavity internal diameter of die 2.The top of described forming punching head 4 projects upwards and is formed with a projection, and described projection diameter is less than the lower end diameter of forming punching head 4, and suitable with the diameter before part bulging to be processed.The junction 6 of described forming punching head 4 top and forming punching head 4 lower end transition is in indent R angle, and the radian at described R angle conforms to the radian of the convex of part shown in Fig. 27, guarantees that forming punching head 4 is deep into the inside of part 5 to be processed smoothly with this.
Below sketch the course of work of the present utility model: binder drift 3 promotes part 5 to be processed and enters in the middle die cavity of die 2, and is pressed abd fixed in die 2 by part 5 to be processed.After compression, forming punching head 4 upwards punching press, due to the projection of its head and the design at indent R angle, makes forming punching head 4 be easy to enter in part 5 to be processed, and completes the bulging treating processing parts 5.After bulging machines, binder drift 3 and forming punching head 4 depart from part, de-feed ring 1 is moved, the part machined is ejected die 2, carry out next step processing.
Because de-feed ring 1 is very weak, when using this device to carry out Continuous maching, promote before next part to be processed 5 enters die 2, to need to carry out reset operation to de-feed ring 1, avoid the damage of de-feed ring 1 and the impact on forming parts at binder drift 3.
Deep-draw part bulging processing mold of the present utility model, by the expansion bulging carried out on pre-profiling product from inside to outside, more effectively can realize this feature of sidewall inwardly protruding of deep-draw part.Be different from the sidewall convex feature that tradition processing needs to be completed by rolling process part, use this device both can complete convenient stable large-scale industrial production, it also avoid slide block structure in tradition processing and, to the damage of part outer wall, further increase the quality of product.
The utility model still has numerous embodiments, all employing equivalents or equivalent transformation and all technical schemes formed, and all drops within protection domain of the present utility model.
