Description

A kind of copper pipe end diameter changing device
Technical field
The utility model relates to a kind of diameter changing devices, relate generally to a kind of variable diameter of copper pipe, can be used for copper pipe flaring, It can be used for copper pipe necking.
Background technique
Copper pipe in use, needs variable diameter in order to mutual connection, and the variable diameter of existing copper pipe end is big It is mostly then variable diameter is carried out to it using hot-working.The wall thickness change of copper pipe in this way is larger, and can not carry out secondary variable diameter. Most process equipment can not meet the needs of processing hose and hard tube simultaneously;Also it can not meet wanting for flaring and necking simultaneously It asks.
Utility model content
To solve the above-mentioned problems, the utility model provides a kind of copper pipe end diameter changing device, including pedestal, the first gas Cylinder, the second cylinder, bottom plate, the first cylinder fixed block, the second cylinder fixed block, clamping, diameter-varying module and handle;First gas Cylinder fixed block is mounted on the top of the pedestal, and first cylinder is mounted on the lower section of first cylinder fixed block;It is described Second cylinder fixed block is fixed on the bottom plate;Second cylinder and second cylinder fixed block are connected and fixed, It is mounted on the bottom plate;The clamping is fixed on the bottom plate, in the lower section of first cylinder, in second cylinder Side;The diameter-varying module is connect with second cylinder;The handle is mounted on the bottom plate, with first cylinder It is connected with second cylinder.
It further, further include cylinder link block;The cylinder link block is connect with second cylinder;The variable diameter Module is mounted on one end of the cylinder link block.
It further, further include fixed ring;The fixed ring is mounted on the bottom plate, the cylinder link block installation In the fixed ring.
It further, further include pressing block below first cylinder, the pressing block is fixed on first cylinder Under, positioned at the top of the clamping.
Further, the clamping includes upper die and lower die;The lower die is fixed on the bottom plate;The upper mold with The pressing block connection;The upper mold and the lower die are all respectively equipped with semi-circular groove.
A kind of copper pipe end diameter changing device provided by the utility model is equipped with the first cylinder, convenient for controlling the clamping Folding, consequently facilitating placing copper pipe;Equipped with the second cylinder, convenient for controlling the diameter-varying module;Equipped with cylinder link block, being convenient for will Replace different diameter-varying modules;The fortune of the cylinder link block is also convenient for equipped with fixed ring convenient for the fixed cylinder link block It is dynamic;Security performance is improved equipped with handle convenient for control cylinder moving;Using cold working, hose and hard tube can be processed, is used Range is wider;Wall thickness change amount is few, is convenient for secondary operation;Different molds is replaced, the demand of flaring and necking is can satisfy, subtracts The investment for having lacked equipment, saves cost.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of diameter changing device provided by the utility model.
Specific embodiment
Embodiment one
As shown in Figure 1, a kind of copper pipe end diameter changing device provided by the utility model, including pedestal 1, the first cylinder 2, Two cylinders 3, bottom plate 4, the first cylinder fixed block 5, the second cylinder fixed block 6, clamping, diameter-varying module 8 and handle 9;Described first Cylinder fixed block 5 is mounted on the top of the pedestal 1, and first cylinder 2 is mounted under first cylinder fixed block 5 Side;Second cylinder fixed block 6 is fixed on the bottom plate 4;Second cylinder 3 and second cylinder fixed block 6 are connected and fixed, and are mounted on the bottom plate 4;The clamping is fixed on the bottom plate 4, in the lower section of first cylinder 2, In the side of second cylinder 3;The diameter-varying module 8 is connect with second cylinder 3;The handle 9 is mounted on the bottom On plate 4, it is connect with first cylinder 2 and second cylinder 3.
Specifically, further including cylinder link block 10;The cylinder link block 10 is connect with second cylinder 3;The change Diameter module 8 is mounted on one end of the cylinder link block 10.
Specifically, further including fixed ring 12;The fixed ring 12 is mounted on the bottom plate 4, the cylinder link block 10 It is mounted in the fixed ring 12.
Specifically, further including pressing block 11 below first cylinder 2, the pressing block 11 is fixed on first cylinder Under 2, positioned at the top of the clamping.
Specifically, the clamping includes upper mold 71 and lower die 72;The lower die 72 is fixed on the bottom plate 4;On described Mould 71 is connect with the pressing block 11;The upper mold 71 and the lower die 72 are all respectively equipped with semi-circular groove.
When in use, when needing to be flared copper pipe end, then flaring die is installed on the cylinder link block 10 Tool;When needing to carry out necking to copper pipe end, then necking die is installed on the cylinder link block 10.Then start the change Diameter device.Copper pipe is placed between the upper mold 71 of the clamping and lower die 72, the upper mold 71 and the lower die 72 are placed on In semi-circular groove.Then push the handle 9, then first cylinder 2 pushes the pressing block 11 to move downward, then it is described on Mould 71 moves downward under the promotion of first cylinder 2, fixed copper pipe.Second cylinder 3 pushes the cylinder to connect simultaneously Connect the movement of block 10, so that the diameter-varying module 8 be pushed to move, thus the diameter-varying module 8 to copper pipe end carry out flaring or Necking.Under the promotion of second cylinder 3, the cylinder link block 10 moves in the fixed ring 12.During installation, it adjusts The center of the whole diameter-varying module 8 is equal with the upper level of the lower die 72, prevents deviation.
It is obvious to a person skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and And without departing substantially from the spirit or essential attributes of the utility model, it can realize that this is practical new in other specific forms Type.Therefore, in all respects, the present embodiments are to be considered as illustrative and not restrictive, this is practical new The range of type is indicated by the appended claims rather than the foregoing description, it is intended that containing for the equivalent requirements of the claims will be fallen in All changes in justice and range are embraced therein.It should not treat any reference in the claims as limiting Related claim.
