Description
Technical field
The utility model relates to die device under the bending, specifically is the adjustable no impression mould of a kind of high duty metal sheet material opening.
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, 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; Simultaneously, also to change the counterdie V-shaped groove of different openings size at any time according to the difference of institute's bending workpieces sheet metal thickness.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, but also will be convenient for changing the openings of sizes of counterdie V-shaped groove.
The utility model content
The technical problem that the utility model will solve provides the adjustable no impression mould of a kind of high duty metal sheet material opening; It is simple in structure; Long service life; But bending different-thickness high duty metal sheet material effectively improves the presentation quality of sheet metal product, increases economic efficiency and is convenient to mold management and maintenance.
The technical scheme of the utility model is:
High duty metal sheet material opening is adjustable no impression mould comprises lower mold body, and the top of described lower mold body has square groove, is provided with two panels that are oppositely arranged in the square groove, is provided with the different backing plate of a plurality of thickness between the sidewall of panel and square groove; The both sides that are positioned at square groove on the lower mold body are provided with one group of screwed hole that connects; Two groups of screws pass the screwed hole of square groove both sides respectively; Two groups of contiguous both ends of screw connect with corresponding panel respectively, and all outside nut is screwed together with being arranged at lower mold body in the other end of two groups of screws; The top of described panel is provided with half slot, is arranged with the carbide alloy pole in the half slot, is installed with the fixedly pressing plate of carbide alloy pole on the panel upper surface, and the circular arc end face of pressing plate is pressed and is located on the sphere of carbide alloy pole.
Described lower mold body is positioned on left and right two outer walls below the square groove and is provided with supporting plate.
All fit on the forward and backward both ends of the surface of described panel and be provided with baffle plate.
The advantage of the utility model:
1, simple in structure, workable, response speed is fast, increases work efficiency;
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, cut down finished cost, be applicable to the Bending Processing of different-thickness sheet material, improved economic benefit, be convenient to administering and maintaining of mould.

The specific embodiment
See Fig. 4, high duty metal sheet material opening is adjustable no impression mould comprises lower mold body 1; The top of lower mold body 1 has square groove 2; Be provided with two panels that are oppositely arranged 3 in the square groove 2, be provided with the different backing plate of a plurality of thickness 4 (see figure 6)s between the sidewall of panel 3 and square groove 2 and (when panel 3 is fitted with the sidewall of square groove 2, can backing plate 4 be supported on the supporting plate 5 and be arranged on the screw 6; See Fig. 1, Fig. 2, Fig. 3), lower mold body 1 is positioned on left and right two outer walls of square groove 2 belows and is provided with supporting plate 5; The both sides that are positioned at square groove 2 on the lower mold body 1 are provided with one group of screwed hole that connects; Two groups of screws 6 pass through the screwed hole of square groove 2 both sides respectively; Two groups of screw 6 contiguous both ends connect with corresponding panel 3 respectively, and the other end of two groups of screws 6 all is screwed together with the nut 7 that is arranged at lower mold body 1 outside; See Fig. 5; The top of panel 2 is provided with half slot; Be arranged with carbide alloy pole 8 in the half slot; Be installed with the fixedly pressing plate 10 of carbide alloy pole 8 on panel 2 upper surfaces, the circular arc end face of pressing plate 10 is pressed and is located on the sphere of carbide alloy pole 8, and all fitting on the panel 2 forward and backward both ends of the surface is provided with baffle plate 9 (seeing Fig. 2, Fig. 3).
When high duty metal sheet material carries out Bending Processing; Earlier the extended distance between lower mold body 1 interior two panels 2 is adjusted to suitable width; Sheet material is placed on the lower mold body 1, utilizes patrix that sheet material is pressed down, workpiece in whole bending process only with panel 2 on carbide alloy pole 8 contact; And pole 8 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 1, eliminated 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 8 has high accuracy, anti abrasive characteristic more than HRC60, has improved the precision and the service life of mould; Lower mold body adopts whole processing, does not need the segmentation splicing, and what carbide alloy pole 8 was placed in panel 2 tops is half slot, and last available grinding machine correct grinding forms, and overall precision is very high, can exchange arbitrarily; Extended distance between the panel 2 can be adjusted and fixes through backing plate 4 according to the workpiece sheet metal thickness; Be fit to the particularly accurate bending requirement of high duty metal sheet material of different-thickness sheet material; Need not change different counterdies, nor, have the advantage of generalization, flexibility with the bending center of adjusting counterdie according to different notch sizes; Workable; Reduced the purchase quantity and the kind of Bending Mould, reduced buying expenses, not only increased economic efficiency but also be convenient to mold management and maintenance.
