Abstract

The utility model discloses a spinning-type skew rolling billet mill including upper and lower rollers fixed on a frame, a hollow billet arranged between the upper and lower rollers, and a core rod, of which one end is inserted in the hollow billet and the other end is connected with a spinning machine. In such a structure that a billet is placed between the upper and lower rollers and that one end of a billet presses against the hollow billet, the spinning machine rotates the core rod which drills into the billet for cogging. At the same time, the upper and lower rollers rotate in opposite directions, so that the billet rotates, and the core rod can be conveniently screwed into the billet. In this way, the billet perforating effect is excellent, the inner structure of the billet is uniform, and the surface quality of inner hole is excellent. And, one-shot forming can be realized.

Description

Rotary extrusion type spinning oblique milling pipe milling train

Technical field

The utility model belongs to the milling equipment technical field, is specifically related to a kind of rotary extrusion type spinning oblique milling pipe milling train.

Background technology

When producing jointless titanium pipe or titanium alloy tube, need to adopt the mode of boring to process pipe.Existing processing mode is that pipe is fixed, and with the pipe perforate, the shortcoming of doing like this is to need secondary punch, could reduce the wall thickness of hollow billet through drilling machine, and the perforate effect is bad.

Summary of the invention

The purpose of the utility model provides a kind of rotary extrusion type spinning oblique milling pipe milling train, and is effective to the perforate of pipe, one-shot forming.

The technical scheme that the utility model adopted is; A kind of rotary extrusion type spinning oblique milling pipe milling train comprises the topping roll and the bottom roll that are fixed on the frame, is provided with hollow billet between topping roll and the bottom roll; One end of core bar extend in the hollow billet, and the other end of core bar is connected with spinning machine.

The utility model rotary extrusion type spinning oblique milling pipe milling train pipe is placed between topping roll and the bottom roll, and pipe one end heads on hollow billet; Spinning machine drives the core bar rotation and pierces the pipe cogging; Topping roll and bottom roll backward rotation make pipe also rotate simultaneously, and it is inner to make things convenient for core bar to be selected into to pipe.Adopt in such a way, the perforate of pipe is effective, can one-shot forming.

Description of drawings

Fig. 1 is the structural representation of the utility model rotary extrusion type spinning oblique milling pipe milling train.

Among the figure, 1. topping roll, 2. bottom roll, 3. hollow billet, 4. core bar, 5. spinning machine, 6. pipe.

The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is elaborated.

The structure of the utility model rotary extrusion type spinning oblique milling pipe milling train; As shown in Figure 1, comprise the topping roll 1 and bottom roll 2 that are fixed on the frame, be provided with hollow billet 3 between topping roll 1 and the bottom roll 2; One end of core bar 4 extend in the hollow billet 3, and the other end of core bar 4 is provided with spinning machine 5.

The course of work of the utility model rotary extrusion type spinning oblique milling pipe milling train is; Pipe 6 is placed between topping roll 1 and the bottom roll 2; And pipe 6 one ends head on hollow billet 3, and spinning machine 5 drives core bar 4 rotations and pierces pipe 6 coggings, simultaneously topping roll 1 and bottom roll 2 backward rotation; Make pipe 6 also rotate, make things convenient for core bar 4 to be selected into to pipe 6 inside.Adopt in such a way, the perforate of pipe is effective, can one-shot forming.
