Description
The utility model relates to the used equipment of a kind of chipless machined metal pipe material, the especially relevant continuous draw-off gear that gives the certain pulling capacity of metal pipe material.
The common in the market continuous processing metal tubing for example equipment of riffled tube or accurate light-wall pipe generally adopts the dish of big diameter disc to pull out unit to roll up the trombone slide material continuously, the moment that when utilizing big disk to rotate with the radius is the arm of force provides continuous drawing power for processed tubing, makes tubing machine-shaping in extruding or spinning apparatus.This drawing structure is easy to make the tubing cross section of machine-shaping to coil the place of drawing in great circle and deforms because continuous drawing power produces by big disk moment, causes the cross section to lose circle, wall unevenness even locates the equivalent damage that ruptures at the point of contact, influences pipe workpiece quality; The big disk dish pulls out unit manufacturing cost height in addition, and it is also very big to take up room.
The purpose of this utility model is to provide a kind of and does not damage processed tubing in metal pipe material continuous drawing process, and the continuously straight pulling device of the metal pipe material of low cost of manufacture, compact conformation.
In order to achieve the above object, the technical solution adopted in the utility model is: the continuously straight pulling device of metal pipe material has fuselage, the two cover chain-drive mechanisms that distribute along processed tubing both sides are housed on the fuselage, and this chain-drive mechanism is made of roller chain, sprocket wheel and sprocket shaft; The periphery of the roller chain of two cover chain-drive mechanisms all is equipped with the withdrawable type piece, but has the type groove of the processed tubing of obvolvent on the withdrawable type piece; Be arranged on week in the roller chain with two pressuring chain plates of fuselage load, and be pressed in opposite to each other on the roller of two cover roller chains.
In order to make roller chain and withdrawable type piece easy to connect, firm, and can reuse after the wearing and tearing of withdrawable type piece, the outer chain sheet of roller chain is directly fixedlyed connected with the withdrawable type piece of banding pattern groove, and the withdrawable type piece has 2 type grooves, and 2 type grooves oppositely are provided with.
For make withdrawable type piece materials few, can repeatedly use after saving cost and the wearing and tearing of withdrawable type piece, the outer chain sheet of roller chain is fixedlyed connected with two fixture blocks, the withdrawable type piece is clamped by two fixture blocks and connects, and the withdrawable type piece has the regular polygon cross section, and has 3 type grooves at least.
For outer chain sheet processing, installation are all made things convenient for, every joint outer chain sheet of roller chain is one-piece type, and cross sectional shape can be " U " type, also can be
Type.
In order to make pressuring chain plate stably press roller chain, and adjustable in pressure, having bar hole on the pressuring chain plate, dog screw is screwed on the fuselage through bar hole, and fuselage is provided with clamp nut, and housing screw is screwed into clamp nut and withstands on the pressuring chain plate.
After adopting such structure, the two cover chain-drive mechanisms owing to distributed along processed tubing both sides, two the cover chain-drive mechanisms the sprocket wheel backward rotation time, processed tubing is lived in the obvolvent under the pressure of pressuring chain plate of the withdrawable type piece of load on the roller chain, along with advancing of withdrawable type piece, give a kind of continuous straight line pulling capacity of processed tubing, the pulling capacity of this straight line is changed over the big disk dish and is pulled out drawback on the unit mechanics, during drawing, there is not the arm of force, fundamentally solved and lost circle, wall unevenness and point of contact breakage problem can not damage processed tubing, have guaranteed pipe workpiece quality; Again because the chain-drive mechanism parts that adopted are that standard component and consumption are few, so this device low cost of manufacture, compact conformation, it is little to take up space.
The embodiment that provides below in conjunction with accompanying drawing is described in further detail the utility model.
