Abstract
The invention relates to the technical field of dies and discloses a die chute structure for oblique blanking. The die chute structure is mounted between an upper die and a lower die of a die. The upper die is provided with male dies while the lower die is provided with female dies. The chute structure comprises rail plates and sliders; the rail plates are of oblique sliding surfaces provided with guide grooves; the sliders are provided with guide blocks matched with the guide grooves and further provided with male die via holes matched with the male dies. Elastic resetting devices are arranged on the sliders and used for resetting the sliders to the original positions after blanking of the male dies. Both the guide grooves and the guide blocks are of square structures. Due to the guide grooves and the guide blocks which are of the square structures, defects of unbalance stressing and shortening of die service life caused by friction force of T-shaped grooves are overcome. The die with the chute structure has the advantages of processing easiness, balanced stressing during operation and greatly prolonged service life.
Description
Technical field
The present invention relates to technical field of mold, more particularly, particularly a kind of mould sliding groove structure for oblique shock wave.
Background technology
As shown in Figure 1, it is the structure chart of existing typical basin frame series products, and structurally it belongs to notch cuttype band clinohedral class product.And on the progressive die is produced, A and B place need stamping-out to fall excess stock acquisition window, in the design of mould structure, because basin frame series products has inclined-plane, be all generally to adopt oblique impact mode to carry out stamping-out.
As shown in Figure 2, stamping-out mode of the prior art adopts the sliding groove structure of slide block and guide-rail plate, and its operation principle is: punch is by B face and the T-slot 21 of guide-rail plate 20, and punch via hole 22 guiding, obtain guiding more accurately, and stamping-out is accurate; But actual in the process of mould, guarantee simultaneously a plurality of the depth of parallelism and flatness, process more difficultly, and do not reach perfect condition.Simultaneously in the material returned, because contact-making surface is too many, between face and face, there is frictional force, make spring can produce and be subject to force unbalance when the material returned, the force analysis of this structure as shown in Figure 3, comprise de-material power F1, punch frictional force F2, de-material spring force F3, self gravitation G and T-slot frictional force F4, because the stress surface of T-shaped groove frictional force F4 is more, in production practices, slide block 23 and punch are easily stuck 20 li of guide-rail plates, and work as punch, do not exit die completely, simultaneously mould starts up time, mould just there will be and draws quick-fried phenomenon, directly reduced the service life of mould.
Summary of the invention
The object of the present invention is to provide a kind of mould sliding groove structure for oblique shock wave, this structure has advantages of that processing is simple, stress balance and can extend die life.
In order to achieve the above object, the technical solution used in the present invention is as follows:
A kind of mould sliding groove structure for oblique shock wave, it is installed between the upper die and lower die of mould, described patrix is provided with punch, described counterdie is provided with die, described sliding groove structure comprises guide-rail plate and slide block, and described guide-rail plate is provided with the sliding surface of inclination, and this sliding surface is provided with gathering sill, described slide block is provided with the guide pad matching with gathering sill, and described slide block is also provided with the punch via hole cooperatively interacting with punch; And on described slide block, be also provided with elastic recovery device, this elastic recovery device for returning to initial position by slide block after punch shock wave, and described gathering sill and guide pad are square structure.
Preferably, described elastic recovery device comprises and is located at the spring eye on slide block and is located at the returning spring in spring eye.
Preferably, described punch is matched in clearance with coordinating of punch via hole.
Compared with prior art, the invention has the advantages that: sliding groove structure of the present invention, owing to having adopted gathering sill and the guide pad of square structure, avoided the frictional force because of T-shaped groove in prior art cause being subject to force unbalance and reduce die life, on the whole, use the mould of this sliding groove structure to there is processing simple, stress balance in the course of the work, the advantage that extends greatly die life.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be described in further detail.
Consult in Fig. 5 shown in Fig. 5 a and 5b, Fig. 6, a kind of mould sliding groove structure for oblique shock wave provided by the invention, it is installed between the upper die and lower die of mould, described patrix is provided with punch 9, described counterdie is provided with die, described sliding groove structure comprises guide-rail plate 3 and slide block 8, described guide-rail plate 3 is provided with the sliding surface of inclination, this sliding surface is provided with gathering sill, described slide block 8 is provided with the guide pad 15 matching with gathering sill, and described slide block 8 is also provided with the punch via hole 13 cooperatively interacting with punch 9; And on described slide block 8, be also provided with elastic recovery device, this elastic recovery device for returning to initial position by slide block 8 after punch 9 shock waves, and described gathering sill and guide pad 15 are square structure.
Used after sliding groove structure of the present invention, owing to having adopted gathering sill and the guide pad 15 of square structure, avoided the frictional force because of T-shaped groove in prior art cause being subject to force unbalance and reduce die life, make the mould with this sliding groove structure there is processing simply, stress balance in the course of the work, the advantage that extends greatly die life.
Concrete, in the present invention, described elastic recovery device comprises the spring eye 14 of being located on slide block 8 and is located at the returning spring 4 in spring eye 14; And the present invention also comprises the pressure guide-rail plate spring 12 being installed on upper padding plate 1 and upper mounted plate 2.
