Abstract

The utility model discloses a pipe clamping device in a PVC pipe production line. The pipe clamping device comprises a rack, two telescopic air cylinders are transversely arranged on the rack, piston rods of the two telescopic air cylinders are fixed to the upper end and the lower end of a vertically-arranged annular clamping block respectively, a plurality of clamping pieces are symmetrically arranged on the annular clamping block along the circumference of the annular clamping block, and the clamping pieces and the annular clamping block are molded in an integrated mode. When the clamping pieces incline inwards under the effect of external force, the clamping pieces always have the tendency of resetting outwards under the effect of metal elasticity of the clamping pieces. A tapered sleeve is vertically arranged on a portion, corresponding to the front ends of the clamping pieces, of the rack, and bore diameters of inner circles of the tapered sleeve are gradually reduced from back to front. When the telescopic air cylinders drive the clamping pieces to move forwards, the front ends of the clamping pieces can extend into the tapered sleeve and incline inwards gradually along the inner circle face of the tapered sleeve until a PVC pipe is clamped. The pipe clamping device has the advantage of being large in clamping force on the PVC pipe.

Description

Pipe clamping device in a kind of pvc pipe material production line

Technical field

The utility model relates to for clamping a kind of pipe clamping device of pvc pipe material production line that the tubing bore is the pvc pipe material of 16-40mm.

Background technology

The pvc pipe material, before the cutting of the cutting machine by pvc pipe material production line, all needs first with pipe clamping device, the pvc pipe material to be fixedly clamped.The structure of the pipe clamping device used at present is: comprise frame, workbench is set on frame, the driving cylinder vertically is installed on the frame above workbench, on the piston rod of driving cylinder, be provided with compact heap, the piston rod that drives cylinder stretches out, the drive compact heap moves down, and the pvc pipe material is pressed on workbench downwards.The shortcoming of this pipe clamping device is: the chucking power to the pvc pipe material is little, and the pvc pipe material is easily shaken in the process of cut machine cutting, has affected the cut quality of pvc pipe material.

The utility model content

It is large that the purpose of this utility model is to provide a kind of chucking power to the pvc pipe material, makes the pvc pipe material in cutting process, be difficult for the pipe clamping device in a kind of pvc pipe material production line shaken.

For achieving the above object, the utility model has adopted following technical scheme: the pipe clamping device in described a kind of pvc pipe material production line, comprise: frame, on frame, laterally be provided with two telescopic cylinders, the piston rod of two telescopic cylinders fixes with the two ends up and down of the annular clamp of vertical setting respectively, on the annular clamp, be symmetrically arranged with some clamp clips along its circumference, all clamp clips and annular clamp are one-body molded, when clamp clip slopes inwardly under external force, clamp clip has the trend outwards resetted all the time under the effect of self metallic elastic, on frame corresponding to clamp clip front end, vertically be provided with a tapered sleeve, the interior Circular Aperture of tapered sleeve reduces from back to front gradually, when telescopic cylinder drove clamp clip and moves forward, the front end of clamp clip can stretch into tapered sleeve and slope inwardly gradually along the inner headed face of tapered sleeve, until clamp the pvc pipe material.

Further, the pipe clamping device in aforesaid a kind of pvc pipe material production line, wherein: in order to the end against the tapered sleeve inner headed face, have the inclined-plane fitted with the tapered sleeve inner headed face on each clamp clip.

By the enforcement of technique scheme, the utlity model has the chucking power of pvc pipe material greatly, make the pvc pipe material in cutting process, be difficult for the advantage of rocking.

The accompanying drawing explanation

Fig. 1 is the structural principle schematic diagram of the pipe clamping device in a kind of pvc pipe material production line described in the utility model.

The specific embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

As Fig. 1, shown in Figure 2, pipe clamping device in described a kind of pvc pipe material production line, comprise: frame 1, on frame 1, laterally be provided with telescopic cylinder 2 and lower telescopic cylinder 3, upper with the annular clamp 4 of vertical setting respectively of the piston rod of the piston rod of upper telescopic cylinder 2 and lower telescopic cylinder 3, lower two ends fix, on annular clamp 4, be symmetrically arranged with some clamp clips 5 along its circumference, all clamp clips 5 are one-body molded with annular clamp 4, when clamp clip 5 slopes inwardly under external force, clamp clip 5 has the trend outwards resetted all the time under the effect of self metallic elastic, on frame 1 corresponding to the front end of clamp clip 5, vertically be provided with a tapered sleeve 6, the interior Circular Aperture of tapered sleeve 6 reduces from back to front gradually, in the process that upper telescopic cylinder 2 and all clamp clips 5 of lower telescopic cylinder 3 drive move forward, the front end of all clamp clips 5 can stretch into tapered sleeve 6 and slope inwardly gradually along the inner headed face of tapered sleeve 6, until clamp pvc pipe material 7, in the present embodiment, on each clamp clip 5, have in order to the end against tapered sleeve 6 inner headed faces the inclined-plane fitted with tapered sleeve 6 inner headed faces, can reduce like this frictional force between clamp clip 5 and tapered sleeve 6 inner headed faces, thereby extend the service life of clamp clip 5 and tapered sleeve 6.

Operation principle of the present utility model is as follows: first pvc pipe material 7 is passed simultaneously to annular clamp 4, frame 1 and tapered sleeve 6, telescopic cylinder 2 and the piston rod of lower telescopic cylinder 3 are inwardly shunk simultaneously, driving annular clamp 4 moves forward with all clamp clips 5, in the process that clamp clip 5 moves forward, the front end of clamp clip 5 can stretch into tapered sleeve 6 and under the effect of himself metallic elastic all the time against the inner headed face of tapered sleeve 6; Along with clamp clip 5 continues to move forward, clamp clip 5 will slope inwardly gradually along the inner headed face of tapered sleeve 6, until after pvc pipe material 7 is clamped, stop the action of upper telescopic cylinder 2 and lower telescopic cylinder 3; Now, cutting machine in pvc pipe material production line can carry out cutting operation to pvc pipe material 7, after cutting, make telescopic cylinder 2 simultaneously protruding with the piston rod of lower telescopic cylinder 3, drive annular clamp 4 and synchronize and move backward with clamp clip 5, clamp clip 5 is understood under the effect of self metallic elastic and is outwards resetted, and leaves the outer surface of pvc pipe material 7, after clamp clip 5 resets fully, stop the action of upper telescopic cylinder 2 and lower telescopic cylinder 3.By aforesaid operations, namely completed pvc pipe material 7 has been clamped and the action of unclamping.The utility model is large to the chucking power of tubing, makes the pvc pipe material be difficult for shaking in the process of cut machine cutting, thereby improves the cut quality of pvc pipe material.
