Abstract
The invention provides a bending die, which comprises a groove-shaped die base, wherein two sides of the inner side of the groove-shaped die base are oppositely provided with fixed blocks respectively, the opposite upper corners of the fixed blocks are provided with circular holes, the circular holes are tangential to the two right-angled edges of the fixed blocks, and the circular holes are in opposite semi-open states; and rollers are arranged in the circular holes. By using the rollers in the semi-open circular holes in the fixed blocks, the outer surface of a part and the rollers have a rolling formation process when the part is bent, so that frictional scratch of the outer surface of the part is avoided, and the sliding friction process of the old-fashioned 'V'-shaped bending die is totally changed; and the structure can be adopted in 'U'-shaped, 'L'-shaped, 'Z'-shaped and arc-shaped parts, so that the outer surfaces of the bent parts are not scratched, and the quality of the products is effectively ensured; and the structure is simple, economic and practical.
Description
Technical field
The present invention relates to the sheet metal cold forming manufacture field in the mechanical industry, specifically is a kind of Bending Mould.
Background technology
Bending is a kind of technology more common in the sheet metal cold working, and is simple to operate because of it, flexible and quick, obtained using widely in mechanical industry.Bending technique has irreplaceable effect in the processing of hardware, especially " L " shape, arc and " Z " shape part, and with respect to using mechanical press and mould molding, processing cost is cheaper, mould as shown in Figure 4.
But, the parts that adopt traditional bending technique to make, in various degree crush injury and scuffing are all arranged on its surface, by analyzing the part bending forming deformation process, the crush injury of finding piece surface be because the R angle on " V " shape groove top is less than normal and the parts deformation process in " V " shape groove in due to the wall friction.This situation, the general serviceability that can not influence part under the not high situation of surperficial quality requirement, can not process.But when the parts presentation quality is had requirement, just can not satisfy customer requirement, the part that is coated with reload request is especially arranged, the characteristics because of poor, the spreadability difference of light-proofness of paint expose undoubtedly open defect, have increased the work difficulty of japanning pre-treatment.
Summary of the invention
The present invention is in order to access appearance quality bending parts preferably, a kind of Bending Mould of special proposition.
For this reason, technical scheme of the present invention is, a kind of Bending Mould, comprise the grooved mold base, it is characterized in that: the inboard both sides at the grooved mold base are respectively equipped with fixed block relatively, and the Shang Jiaochu that fixed block is relative is provided with circular hole, and two right-angle sides of this circular hole and fixed block are tangent, and circular hole is semi-open relatively state, is provided with roller in the circular hole.
Beneficial effect:
The present invention utilizes the rolling of roller in two semi-open relatively circular holes, making needs the outer surface of bending parts and the process that roller has a rolling, in the process of bending, the shaping of rolling together of roller and parts, avoided the friction of parts outer surfaces to scratch, changed the process of old-fashioned " V " font Bending Mould sliding friction fully, when running into " U " font, " L " font, can adopt this kind structure when " Z " font and arc parts, the outer surface that folds the parts that come does not so all have the phenomenon of scuffing, has guaranteed the quality of product effectively, this is simple in structure, and is economical and practical.

Fig. 2 is master's TV structure schematic diagram of the present invention.
Fig. 3 is a left TV structure schematic diagram of the present invention.
Fig. 4 is the left TV structure schematic diagram of mould in the background technology.
1 is the grooved mold base among the figure, the 2nd, and fixed block, the 3rd, circular hole, the 4th, roller.
The specific embodiment
The present invention such as Fig. 1, Fig. 2, shown in Figure 3.
The present invention is respectively equipped with fixed block 2 relatively on the inboard both sides of grooved mold base 1, and fixed block 2 relative Shang Jiaochu are provided with circular hole 3, and two right-angle sides of this circular hole 3 and fixed block 2 are tangent, and circular hole 3 is semi-open relatively state, is provided with roller 4 in the circular hole 3.
In use roller 4 is penetrated in the circular hole 3, utilize the rolling of roller 4 in two semi-open relatively circular holes 3, making needs the outer surface of bending parts and the process that roller 4 has a rolling, roller 4 and the parts shaping of rolling together in the process of bending, can not rub scratches the parts outer surface, has changed the process of old-fashioned " V " font Bending Mould sliding friction fully, when running into " U " font, " L " font can adopt this kind structure when " Z " font and arc parts.
