Description
Technical field
The utility model belongs to the stretching-machine technical field, specifically, and the particularly cartridge device on the stretching-machine.
Background technology
At present, stretching-machine is when carrying out pipe fitting stretching work, be that the tube head of clamping pipe fitting by the cartridge device on the power buggy is mobile together, make the pipe fitting pass through the centre bore of mould and moulding, existing deficiency is: the cartridge device complex structure, operate comparatively loaded down with trivial detailsly, and fastness and the reliability to the pipe fitting clamping is relatively poor in drawing process.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of stretching-machine cartridge device that can clamp pipe fitting all the time.
The technical solution of the utility model is as follows: a kind of stretching-machine cartridge device, comprise collet body (1) and fixture block (2), two symmetrical wearing plates (3) are fixedly arranged in described collet body (1), two wearing plates (3) are " eight " font and distribute, distance between two wearing plates (3) increases from front to back gradually, between two wearing plates (3), be provided with two symmetrical fixture blocks (2), the rear end of each fixture block (2) all is equipped with dop (4), connect by shifting block (5) between the dop (4) of two fixture blocks (2), and be connected with handle (6) on the shifting block (5), between the wearing plate (3) of described fixture block (2) and respective side, be provided with needle roller frame (7), one row's needle roller (8) is installed on this needle roller frame (7) from front to back, the periphery of each needle roller (8) cooperates with corresponding fixture block (2) and wearing plate (3), the rear end of described needle roller frame (7) is connected with adjustment seat (10) by torsion spring (9), and this adjustment seat (10) fixes by the rear end of cushion block (11) with collet body (1).
Adopt above technical scheme, the end of pipe fitting is stretched between two fixture blocks, manually pulls handle, makes handle drive shifting block, and shifting block drives dop and fixture block is mobile together, and two fixture blocks are clamped pipe fitting; After letting go, the power that clamps pipe fitting this moment is the frictional force that component weight such as shifting block, handle produce, when whole collet body drive internal structure moves together backward, the inertia of parts such as shifting block, handle also applies a power forward to two fixture blocks, the needle roller frame is clamped between fixture block and the corresponding wearing plate, this all makes the frictional force between pipe fitting and the fixture block increase, and the clamping force of two fixture blocks increases; Simultaneously, pipe fitting also produces a pulling force to two fixture blocks, and two fixture blocks move forward under the pulling force effect, have also increased the pressure to pipe fitting, finally, can guarantee pipe fitting is clamped all the time backward in the process of mobile trombone slide at collet body.
In order to increase the snap-in force to pipe fitting, further improve the fixing that clamps pipe fitting, be symmetrically arranged with serration at the opposite face of two fixture blocks (2).
Be equipped with adjustment screw (12) from front to back in the rear end of described adjustment seat (10), this adjustment screw (12) and adjustment seat (10) threaded engagement, and the front end of adjustment screw (12) is aimed at the rear end of needle roller frame (7).Adjustment screw is erected spacing effect to needle roller, and the spacing distance of adjustment screw can regulate as required, and is not only convenient but also quick.
Beneficial effect: the utility model can clamp pipe fitting all the time, and the drawing process of pipe fitting can be finished smoothly, has characteristics such as reasonable in design, simple in structure, easy to operate, good reliability.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1, fixedly have 3, two wearing plates 3 of two symmetrical wearing plates to be " eight " font in collet body 1 and distribute, the distance between two wearing plates 3 increases from front to back gradually.Be provided with two symmetrical fixture blocks 2 between two wearing plates 3, fixture block 2 is the inclined-plane near the face of wearing plate 3, and this inclined-plane parallels with wearing plate 3.Opposite face at two fixture blocks 2 is symmetrically arranged with serration, to increase the snap-in force to pipe fitting.All be equipped with in the rear end of two fixture blocks 2 between the dop 4 of 4, two fixture blocks 2 of dop and connect by shifting block 5, and be connected with handle 6 on the shifting block 5.
As shown in Figure 1, be provided with needle roller frame 7 between the wearing plate 3 of fixture block 2 and respective side, this needle roller frame 7 is strip, and row's needle roller 8 is installed on the needle roller frame 7 from front to back, and the periphery of each needle roller 8 cooperates with corresponding fixture block 2 and wearing plate 3.The rear end of described needle roller frame 7 is connected with adjustment seat 10 by torsion spring 9, and two adjustment seats 10 also are left-right symmetry and distribute.Described adjustment seat 10 fixes by the rear end of cushion block 11 with collet body 1, is equipped with adjustment screw 12 from front to back in the rear end of each adjustment seat 10, this adjustment screw 12 and adjustment seat 10 threaded engagement, and the front end of adjustment screw 12 is aimed at the rear end of needle roller frame 7.
Operation principle of the present utility model is as follows:
The end of pipe fitting 13 is stretched between two fixture blocks 2, manually pulls handle 6, makes handle 6 drive shifting block 5, and shifting block 5 drives dop 4 and fixture block 2 is mobile together, and two fixture blocks 2 are clamped pipe fitting 13; After letting go, when power buggy drove whole collet body 1 and internal structure thereof and moves backward together, needle roller frame 7 trace forward was mobile, and was clamped between fixture block 2 and the corresponding wearing plate 3.Trombone slide is finished or pipe fitting when midway breaking, and power buggy stops, and the pulling force that acts on the collet body 1 disappears, and under the screen resilience effect of torsion spring 9, needle roller frame 7 trace backward is mobile, and two fixture blocks 2 can be opened a little, and pipe fitting 13 is taken off.
