Abstract

The utility model relates to a non-indentation mould used for sheet metal folding; one or a plurality of V-shape grooves are arranged on an integral mould steel, the two sides of the open position of each V-shape groove have circular arc R, the two sides of the open positions of the V-shape grooves are provided with O-shape grooves, column bodies whose section diameter matches with the diameter of the O-shape grooves are arranged in the O-shape grooves, the circular arc R of the exposed parts of the column bodies coincides with the circular arc R of the two sides of the open positions of the V-shape grooves. When the mould is used, the friction force between the mould and the work piece is reduced, and the work piece cannot be stretched and damnified or the indentation does not occur because the column bodies can rotate in the O-shape grooves.

Description

No impression panel beating Bending Mould

Technical field

The utility model relates to a kind of machine die, particularly a kind of mould that is used for the panel beating bending.

Background technology

Existing panel beating Bending Mould is generally processed by the mould steel of an integral body, when bender is worked, because the circular arc R of both sides, V-type channel opening position is bigger to the workpiece frictional force of processing, impression can be pulled or occur to surface of the work, for less demanding processing, this pull or impression can be left in the basket, but for some processing of having relatively high expectations, when for example Jia Gong workpiece is the metallic plate of surperficial aluminizing zinc, because this sheet material is light relatively, this pull or impression apparent in view, influence outward appearance and product quality, therefore need be improved mould.

Summary of the invention

The purpose of this utility model provides a kind of panel beating Bending Mould that can not produce impression or pull workpiece.

The purpose of this utility model is achieved through the following technical solutions: a kind of no impression panel beating Bending Mould, on the mould steel of an integral body, have one or more V-type grooves, there is circular arc R the both sides at V-type channel opening position, it is characterized in that having O type groove in both sides, V-type channel opening position, the cylinder that its diameter of section and O type groove diameter are complementary is housed in this O type groove, and the circular arc R of the circular arc R of this cylinder exposed parts and both sides, V-type channel opening position matches.

Said cylindrical material can be metal or nonmetallic materials in the such scheme.Metal material can be steel, copper, zinc-containing alloy etc., and nonmetallic materials can be nylon, bakelite or engineering plastics etc.Material requirements has certain wear-resisting and resistance to pressure.

The basis of the technical solution adopted in the utility model is, because O type groove and cylindrical existence, when bender is worked; along with pressing down of patrix; this cylinder can rotate in O type groove, the frictional force of mould and surface of the work is reduced, thereby protected surface of the work.The method of manufacture and use thereof of this mould is, in the both sides of the opening of the V-type groove of existing mold,, make or utilize commercially available and cylinder O type groove coupling separately with wire cutting method or other similar approach processing O type groove, it is penetrated the O type groove from the mould side, can use.

The utility model has the advantages that: one, can avoid impression is pulled or produced to workpiece, improve the quality of product; Two, can on existing panel beating Bending Mould, transform, simple and easy to do; Three, because cylinder can be easy to extract replacing out from the mould both sides, keep in repair more convenient.

Fig. 1 is the front view of the said single-V groove mould of the utility model.

Fig. 2 is the vertical view of the said single-V groove mould of the utility model.

Fig. 3 is the front view of the said many V-types groove mould of the utility model

The specific embodiment

The said no impression mould of present embodiment is single-V groove mould or many V-types groove mould, and V-type groove 2 is arranged on mold base 1, and the opening both sides of V-type groove 2 have O type groove 3, in O type groove 3 cylinder 4 are housed, as Fig. 1, Fig. 2 and shown in Figure 3.The material of the cylinder 4 of present embodiment is nylon 6 or nylon 66, wherein the subtended angle of the V-type groove 2 of single-V groove mould is 30 degree, the extended distance 24mm of V-type groove 2, the internal diameter of O type groove 3 and the section radius of cylinder 4 are complementary, the former is more bigger than the latter, and cylinder 4 can be rotated at mold pressure lower edge O type groove.

Claims

1, a kind of no impression panel beating Bending Mould, on the mould steel of an integral body, have one or more V-type grooves, there is circular arc R the both sides at V-type channel opening position, it is characterized in that having O type groove in both sides, V-type channel opening position, the cylinder that its diameter of section and O type groove diameter are complementary is housed in this O type groove, and the circular arc R of the circular arc R of this cylinder exposed parts and both sides, V-type channel opening position matches.

2, no impression panel beating Bending Mould according to claim 1 is characterized in that said cylindrical material can be metal or nonmetallic materials, and said metal material is steel or copper, and nonmetallic materials are nylon or bakelite.
