Abstract
The utility model relates to a steel pipe head maker, in particular to a roller spinning device of a steel pipe head maker. The roller spinning device comprises a self-centering three-jaw chuck, and three jaws are connected to one side of the self-centering three-jaw chuck and are respectively connected with rollers. The roller spinning device is simple, reasonable and compact in structure, easy in production and manufacturing and high in head making precision, increases head making precision and efficiency of cold drawn steel pipes, can be widely applied to making heads of large-caliber cold drawn seamless pipes, is particularly applicable to a large-tonnage hydraulic cold-drawn pipe machine to produce seamless steel pipes, and has excellent popularization values.
Description
Technical field
The utility model relates to a kind of steel pipe system machine, relates in particular to the running roller spinning apparatus of a system machine.
Background technology
A steel pipe system machine is applicable to the solid drawn tube industry, especially for middle heavy caliber solid drawn tube industry, is mainly used in the steel pipe head system head of steel pipe before cold-drawn, belongs to seamless steel pipe manufacturing equipment technical field.Existing cold drawn steel control head apparatus is mainly used pneumatic hammer, board drop hammer, rotary forging machine, and its complex structure, a system precision is low, and made steel pipe head pricked extremely, make troubles for the processing of road, back, and made head is longer, and metal loss is big.For middle large diameter steel pipe, existing system head apparatus is powerless.
The utility model content
The purpose of this utility model mainly provides a kind of simple in structure, the running roller spinning apparatus of a steel pipe system easy to use machine.
The purpose of this utility model is achieved in that the running roller spinning apparatus of a kind of steel pipe system machine, comprises three-jaw self-centering chuck, and a side of three-jaw self-centering chuck connects three jaws, connects running roller on each jaw respectively.
During steel pipe system, by adjusting the position of three running rollers on the three-jaw self-centering chuck, fit in the shape that to make the steel pipe head, at first the steel pipe head is heated to the 900-1000 degree on intermediate frequency coil, the roller-way of pushing the oil cylinder back by a system machine is transported to steel pipe near behind the position of running roller spinning and halts again.Clamp steel pipe, start main transmission, transmission device drives three-jaw self-centering chuck and rotates together, thereby driving three-jaw rotates together, make three running rollers that are installed on the three-jaw rotate together, after three running roller rotations, the bus on the running roller forms the space of a sealing, and this space is exactly the shape after steel pipe need be made head.After steel pipe clamps, push oil cylinder and promote the clamping device clamps steel pipe and advance, under the effect of the pushing force of oil cylinder, steel pipe just forms the shape that the system head needs after by three running rollers.
The simple and reasonable compactness of the utility model is manufactured easily, a system precision height.Improved the precision and the efficient of cold drawn steel control head, the system head of heavy caliber cold-drawing seamless pipe in can being widely used in, particularly suitable large-tonnage hydraulic pressure cold drawing machine is produced seamless steel pipe, has excellent popularization to be worth.
Each running roller of the present utility model is connected with jaw by round nut, bearing gland, single-row tapered roller bearing respectively.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is an A portion enlarged drawing among Fig. 1.
The specific embodiment
As shown in Figure 1, 2, running roller spinning apparatus for a steel pipe system machine, comprise three-jaw self-centering chuck 12, a side of three-jaw self-centering chuck 12 connects three jaws 13, connects running roller 16 by round nut 14, bearing gland 15, the 3rd single-row tapered roller bearing 17 respectively on each jaw 13.Three running rollers all can be mixed with different passes (change running roller and can realize that wide group of steel pipe is apart from the system head) at diverse location.
The opposite side of three-jaw self-centering chuck 12 connects drive unit by flange, treats that a system steel pipe 1 is set in the three-jaw self-centering chuck 12 by oil cylinder.
Claims (2)
