Abstract
The utility model discloses a demoulding device for a lateral flanged hole of a semispherical shell. The demoulding device comprises a baseplate, a support seat arranged on the baseplate, a female die movably arranged on the support seat and being capable of reciprocating in the horizontal direction, a male die fixed on the support seat and matched with the female die, an unloading plate sleeved on the male die and being capable of sliding horizontally along the male die, and a guide post of which one end is connected with the unloading plate and the other end is arranged on the support seat. The demoulding device is utilized to greatly reduce moulding surface deformation and surface damage of parts in the demoulding process, and a compression spring supports a returning device to enable a workpiece to be uniformly stressed in the demoulding process, so that the wall thickness uniformity and moulding surface quality of a formed flanged hole are greatly improved, the defects of deformation, impact damage and the like of the workpiece, caused during forced demoulding, are effectively avoided, and the benefits of stabilizing the forming quality, improving the product moulding surface and surface qualities and increasing the demoulding efficiency are obtained.
Description
Technical field
The utility model relates to the machine die processing technique field, and is particularly related to a kind of Loadings On Hemispherical Shell side direction flanging bore stripper apparatus.
Background technology
The flange of flange hole has changed the Type of Welding of flange and hole in the past, has greatly improved weld seam inherent quality and soldering reliability.As a kind of comparatively ripe technology, obtaining using comparatively widely at the bottom of carrier rocket tank case and on pressurizing transmission system spherical shell housing.
Traditional flange hole flanging forming apparatus structure is simple, there is no stripper apparatus, adopt hand ejection after hole flanging is shaped, not only forming efficiency is low, forced stripper mechanism easily causes the part type facial disfigurement simultaneously, the defectives such as damage in the surface, scuffing, in addition, due to the support that there is no stripper apparatus, in turn-up process, part soars, easily wave, thereby cause flanging bore hole wall height dimension inconsistent, the thick lack of homogeneity of the hole wall of flange.And on the tank Loadings On Hemispherical Shell in the carrier rocket model, be designed with the flange flanging bore of horizontal direction, because the flanging bore aperture is less, must carry out hot forming, and material is softer under heated condition, as adopt forced stripper mechanism, not only can cause serious the drawing, damage of material surface, but also can bring certain hidden danger to safety in production.
The utility model content
In view of this, the utility model is intended to solve prior art in knockout course, causes the part type facial disfigurement, the technical problems such as damage in the surface, scuffing.The utility model provides a kind of Loadings On Hemispherical Shell side direction flanging bore stripper apparatus, and it comprises: base plate; Supporting seat is arranged on described base plate; Former is movably set on described supporting seat, and can move back and forth along horizontal direction; Formpiston is fixed on described supporting seat, coordinates with described former; Stripper is set on described formpiston, does horizontal slip along described formpiston; Guide pillar, an end is connected with described stripper, and an end is arranged on described supporting seat; And guide plate, be connected by screw in described stripper bottom.
Further, described supporting seat is connected with described base plate by dormant bolt.
Further, described stripper apparatus also comprises: Compress Spring is set on described guide pillar, and two ends are embedded in respectively in described stripper and described supporting seat.
Further, described guide pillar is arranged on described supporting seat, and an end is connected with nut.
In sum, the utility model provides a kind of Loadings On Hemispherical Shell side direction flanging bore stripper apparatus, part type facial disfigurement and surface damage in knockout course have greatly been reduced, support discharging device by Compress Spring, make workpiece uniform stressed in knockout course, greatly improve shaping flanging bore evenness of wall thickness and profile quality, effectively avoided workpiece deformation that forced stripper mechanism causes, the defective such as damage, obtain the stable formation quality, improved product profile and surface quality, improved the beneficial effects such as demoulding efficiency.
Description of drawings
Figure 1 shows that the structural representation of the Loadings On Hemispherical Shell side direction flanging bore stripper apparatus that the utility model one embodiment provides.
The specific embodiment
For the purpose of this utility model, feature are become apparent, below in conjunction with accompanying drawing, the specific embodiment of the present utility model is further described.
See also Fig. 1, it is depicted as the structural representation of the Loadings On Hemispherical Shell side direction flanging bore stripper apparatus that the utility model one embodiment provides.
This Loadings On Hemispherical Shell side direction flanging bore stripper apparatus comprises: base plate 1; Supporting seat 2 is arranged on described base plate 1; Former 3 is movably set on described supporting seat 2, and can move back and forth along horizontal direction; Formpiston 4 is fixed on described supporting seat 2 by bolt 10, coordinates with described former 3; Stripper 5 is set on described formpiston 4, does horizontal slip along described formpiston 4; Guide pillar 8 one ends are connected with described stripper 5, and an end is arranged on described supporting seat 2.
In the utility model embodiment, described stripper apparatus also comprises: guide plate 6 is connected to described stripper 5 bottoms by screw 12.
In the utility model embodiment, described guide plate 6 is copper guide plate, effectively reduces wear, and improves mechanism service life.
In the utility model embodiment, described supporting seat 2 is connected with described base plate 1 by dormant bolt 11.
In the utility model embodiment, described stripper apparatus also comprises: Compress Spring 9 is set on described guide pillar 8, and two ends are embedded in respectively in described stripper 5 and described supporting seat 2.
Under Compress Spring 9 effects, screen resilience promotes stripper 5 workpiece is deviate from, in the utility model embodiment, adopt many Compress Springs 9, as 4, support stripper 5, make workpiece uniform stressed in knockout course, effectively reduce the part type facial disfigurement, improve shaping flanging bore evenness of wall thickness and profile quality.
In the utility model embodiment, described guide pillar 8 is arranged on described supporting seat 2, and an end is connected with nut 7, regulates the initial alignment of stripper 5 by nut.
The device that the utility model provides is installed by shown in Figure 1, and after fixing with the platen face, bottom outlet on Loadings On Hemispherical Shell is enclosed within on formpiston 4 neck positions, then rotating nut, adjust guide pillar 8, till making the stripper 5 that is attached thereto be close to the Loadings On Hemispherical Shell inwall, then complete the flanging forming in hole by former 3 horizontal movement to the right, after flange is completed, former 3 is return left to be resetted, stripper 5 is moved to the left under the effect of Compress Spring 9 screen resiliences, and promotes workpiece it is deviate from from formpiston 4, completes knockout course.
The utility model has solved in the past after the flange hole flange must forced stripper mechanism, and the problems such as the profile that causes distortion and surface damage have reached the stable formation quality, improved product profile and surface quality, improve the beneficial effect of demoulding efficiency.
In sum, the Loadings On Hemispherical Shell side direction flanging bore stripper apparatus that the utility model embodiment provides, part type facial disfigurement and surface damage in knockout course have greatly been reduced, support discharging device by Compress Spring 9, make workpiece uniform stressed in knockout course, shaping flanging bore evenness of wall thickness and profile quality have greatly been improved, effectively avoided workpiece deformation that forced stripper mechanism causes, the defective such as damage, obtain the stable formation quality, improved product profile and surface quality, improved the beneficial effects such as demoulding efficiency.
