Abstract
The utility model discloses a high-strength sheet metal dent-free die. The die comprises a lower die body, wherein one or a plurality of V-shaped grooves are arranged on the lower die body, a semi-circular groove and a step-shaped groove are respectively arranged on both sides of notches at top ends of V-shaped grooves on the lower die body, hard alloy round rods are clamped inside semi-circular grooves, pressing plates which are used for fixing hard alloy round rods are fixedly installed inside step-shaped grooves, and arc end faces of pressing plates are pressed on spherical surfaces of hard alloy round rods. The die is simple in structure, long in service life, can be used for bending high-strength metal sheets of different thickness, can effectively improve the appearance quality of sheet metal products and can improve economic benefits.
Description
Technical field
The utility model relates to die device under a kind of bending, specifically is that a kind of high duty metal sheet material does not have the impression mould.
Background technology
At present; Bending Mould is a die apparatus commonly used in the sheet metal product machine-shaping; Development along with industries such as engineering machinery, automobile, track traffic, boats and ships, Aero-Space, electrical instrumentation and building decorations; Both at home and abroad panel beating enterprise requires increasingly highly to forming accuracy, presentation quality, the complex-shaped degree of sheet metal product, and this is simultaneously also to the accuracy of manufacture of Bending Mould and the very high requirement that also proposes service life.The V-shaped groove that the counterdie used of tradition bending has openings of sizes to differ usually is used for the sheet material of bending different-thickness.During bending under the effect of bending power; Sheet material moves and receives the extruding of bending power along counterdie V-shaped groove mouth edge; Form tangible impression defective on the sheet metal part surface after the shaping thereby make, the width of imperfect tape is about 0.414 times of V-shaped groove mouth, has had a strong impact on the presentation quality of product.Solve the above-mentioned defective that occurs in traditional bending, just must overcome the mobile frictional force that sheet material is formed with the counterdie V-shaped groove of sheet material in the bending process.
The utility model content
The technical problem that the utility model will solve provides a kind of high duty metal sheet material does not have the impression mould, and it is simple in structure, and long service life, but bending different-thickness high duty metal sheet material effectively improve the presentation quality of sheet metal product, increase economic efficiency.
The technical scheme of the utility model is:
High duty metal sheet material does not have the impression mould; Comprise lower mold body; Described lower mold body is provided with one or more V-shaped grooves, and the both sides that are positioned at V-shaped groove top notch on the described lower mold body are provided with a half slot and a step groove, are arranged with the carbide alloy pole in the described half slot; Be installed with the pressing plate that is used for fixing the carbide alloy pole in the step groove, the circular arc end face of pressing plate is pressed and is located on the sphere of carbide alloy pole.
All fit and be provided with the termination baffle plate in the bottom that is positioned at each carbide alloy pole end face on the described lower mold body.
The advantage of the utility model:
1, simple in structure, whole processing, it is convenient to manufacture;
2, the carbide alloy pole is in the sheet material Bending Processing; Can rotate along the moving direction of sheet material; Make workpiece become present rolling friction by traditional static friction contacting stressed back with lower mold body; Eliminate impression and scratch that surface of the work produces owing to being squeezed, effectively improved the presentation quality and the precision of workpiece;
3, V channel opening size can be fit to the particularly accurate bending requirement of high-strength plank of different-thickness sheet material according to workpiece sheet material Thickness Design, reduces product cost, increases economic efficiency.

Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the structural representation of lower mold body.
The specific embodiment
See Fig. 1, Fig. 2; High duty metal sheet material does not have the impression mould; Comprise lower mold body 1 (see figure 3), lower mold body 1 is provided with two V-shaped grooves 5, and the both sides that are positioned at two V-shaped groove 5 top notches on the lower mold body 1 are provided with a half slot 6 and step groove 7 (see figure 3)s; Be arranged with carbide alloy pole 2 in the half slot 6; Be installed with the pressing plate 3 that is used for fixing carbide alloy pole 2 in the step groove 7, the circular arc end face of pressing plate 3 is pressed and is located on the sphere of carbide alloy pole 2, all fits and be provided with termination baffle plate 4 in the bottom that is positioned at each carbide alloy pole 2 end face on the lower mold body 1.
Patrix is pressed into workpiece in the process of lower mold body 1; Because the carbide alloy pole 2 on 5 mouthfuls of both sides of V-shaped groove protrudes in the inclined-plane of V-shaped groove 5; Make workpiece in whole bending process, not contact V-shaped groove 5 inclined-planes; Only contact, and pole 2 can rotate along the moving direction of sheet material, make workpiece stressedly then become present rolling friction contacting by traditional static friction with lower mold body with carbide alloy pole 2; Eliminate impression and scratch that surface of the work produces owing to being squeezed, effectively improved the presentation quality and the precision of workpiece.Wherein the hardness of carbide alloy pole 2 has high accuracy, anti abrasive characteristic more than HRC60, has improved the precision and the service life of mould; Lower mold body 1 adopts whole processing, does not need the segmentation splicing, and what the carbide alloy pole was placed in the both sides of V-shaped groove 5 top notches is half slot 6, and last available grinding machine correct grinding forms, and overall precision is very high; V-shaped groove 5 openings of sizes can be fit to the particularly accurate bending requirement of high-strength plank of different-thickness sheet material according to workpiece sheet material Thickness Design, have filled up the market vacancy.
Claims (2)
1. high duty metal sheet material does not have the impression mould; Comprise lower mold body; Described lower mold body is provided with one or more V-shaped grooves, it is characterized in that: the both sides that are positioned at V-shaped groove top notch on the described lower mold body are provided with a half slot and a step groove, are arranged with the carbide alloy pole in the described half slot; Be installed with the pressing plate that is used for fixing the carbide alloy pole in the step groove, the circular arc end face of pressing plate is pressed and is located on the sphere of carbide alloy pole.
