Abstract
The utility model relates to a non-bending die for copper bars, which is used for high-and-low pressure complete equipment. The non-bending die for copper bars is characterized in that one or more V-shaped notches are arranged on a piece of integral die steel, and two sides of the opening of each V-shaped notch are provided with circular arcs R. Further, two sides of the opening of each V-shaped notch are provided with O-shaped slots, a cylinder with the section diameter matching with the diameter of the O-shaped slot is mounted in each O-shaped slot, and a circular arc R of the exposed portion of each cylinder matches with the circular arcs R on two sides of the opening of the V-shaped notch. Due to the O-shaped notches and the cylinders, the cylinders can rotate in the O-shaped slots along with pressing of an upper die when a bending machine works, friction force among the die and surfaces of copper bars is reduced, the copper bars can not be strained or cause marks, and surfaces of the copper bars are protected.
Description
Technical field
The utility model relates to machine die in a kind of high-low pressure complete set of equipments processing operation, particularly a kind ofly is used for the mould that high-low pressure complete set of equipments copper bar does not have bending.
Background technology
Copper bar does not have Bending Mould in the existing high-low pressure complete set of equipments, generally the mould steel by an integral body processes, when bender is worked, because the circular arc R of both sides, v type channel opening position is bigger to the copper bar frictional force of processing, impression can be pulled or occur in the copper bar surface, 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 copper bar is the metallic plate of surperficial aluminizing zinc and since this sheet material relatively the light, 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 no Bending Mould that can not produce impression or pull copper bar.The utility model is used for the high-low pressure complete set of equipments, the principal character that copper bar does not have the mould of bending is: a kind ofly be used for the mould that high-low pressure complete set of equipments copper bar does not have bending, 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, have 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.
The said cylindrical material of the utility model can be metal or nonmetallic materials.Metal material can be steel, iron, zinc-containing alloy etc., and nonmetallic materials can be bakelite or engineering plastics etc.Material requires to have certain wear-resisting and resistance to pressure.
The utility model is used for the high-low pressure complete set of equipments; what copper bar did not have technical scheme that the mould of bending adopts 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 on mould and copper bar surface is reduced, can not pull and produce impression, thereby protected the copper bar surface.The method of manufacture and use thereof that this copper bar does not have Bending Mould is, both sides at the opening of the V-type groove of existing mold, with wire cutting method or other similar approach processing O type groove, make or utilize cylinder commercially available and O type groove coupling separately, it is penetrated the O type groove from the mould side, can use.
The advantage that the utility model is used for high-low pressure complete set of equipments copper bar and does not have the mould of bending is: one, can not pull and produce impression to copper bar, improve the quality and the fineness 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.
Description of drawings
Fig. 1 is that the utility model is used for the front view that high-low pressure complete set of equipments copper bar does not have the said single-V groove mould of mould of bending.
Fig. 2 is that the utility model is used for the vertical view that high-low pressure complete set of equipments copper bar does not have the said single-V groove mould of mould of bending.
Fig. 3 is that the utility model is used for the front view that high-low pressure complete set of equipments copper bar does not have the said many V-types groove mould of mould of bending.
The specific embodiment
The utility model is used for the mould that high-low pressure complete set of equipments copper bar does not have bending, said no impression mould comprises single-V groove mould or many V-types groove mould, its principal character is that V-type groove 2 is arranged on mold base 1, the opening both sides of V-type groove 2 have O type groove 3, in O type groove 3, cylinder 4 is housed, the material of cylinder 4 of the present utility model is metal or nonmetallic materials, but the material requirement is that certain wear-resisting and resistance to pressure is arranged; 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, and the internal diameter of O type groove 3 is more bigger than cylinder 4, and cylinder 4 can be rotated at mold pressure lower edge O type groove.
The utility model is used for the mould that high-low pressure complete set of equipments copper bar does not have bending, does not pull and impression through the copper bar of this mould bending, has improved the quality and the fineness of product; Can transform on existing panel beating Bending Mould, simple and easy to do, material-saving saves time; Because the cylinder physical efficiency is easy to extract replacing out from the mould both sides, keeps in repair more convenient.
Claims (1)
1. one kind is used for the mould that high-low pressure complete set of equipments copper bar does not have bending, 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, have 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; Cylindrical material can be metal or nonmetallic materials, but material has certain wear-resisting and resistance to pressure.
