Abstract
The utility model relates to the technical field of pipe production, and in particular relates to a vacuum calibration die which comprises a calibration bushing and a calibration die fixed part which is connected with one end of the calibration bushing, wherein the calibration bushing comprises a first vacuum forming section, a second vacuum forming section and a third vacuum forming section which are sequentially connected with one another from the end where the calibration die fixed part is arranged, the inner parts of the first vacuum forming section and the second vacuum forming section are respectively provided with a cylindrical cavity, and the inner diameter of the second vacuum forming section is gradually increased and then gradually decreased from the connection part between the second vacuum forming section and the first vacuum forming section to the connection part between the second vacuum forming section and the third vacuum forming section. With the vacuum calibration die, the physical and chemical performance indexes and surface smoothness of a pipe are improved.
Description
Technical field
The utility model relates to the tubing production technical field, is specifically related to a kind of vacuum sizing cover.
Background technology
The vacuum sizing cover is the mode that generally adopts in the plastic conduit processing and forming, and its structure is as shown in Figure 1, mainly comprises columniform sizing sleeve pipe and calibration sleeve fixture; The sizing inside pipe casing has a columniform cavity; Its operation principle is through vacuum pipe is adsorbed in the calibration sleeve inside pipe wall, and spraying cooling water to be cooled off; After the hauling machine traction, make the tubing finished product, the fast efficient of speed of production is high.But existing this vacuum sizing cover is simple shaping jig on the one hand, and the raising of the physical and chemical index of tubing is not helped much; On the other hand, the tubing apparent mass is not ideal, and surface smoothness is relatively poor.
Summary of the invention
The technical problem that the utility model solves is the deficiency that overcomes prior art, and a kind of vacuum sizing cover that improves tubing physical and chemical index and surface smoothness is provided.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is following:
A kind of vacuum sizing cover; Comprise sizing sleeve pipe and the calibration sleeve fixture that is connected sizing sleeve pipe one end; Said sizing sleeve pipe comprises the first Vacuum shaping section, the second Vacuum shaping section and the 3rd Vacuum shaping section that end is connected successively from calibration sleeve fixture place; Said first Vacuum shaping section and the 3rd Vacuum shaping intersegmental part are cylindrical cavity, and the internal diameter of the said second Vacuum shaping section is from dwindle to increasing gradually earlier with the 3rd Vacuum shaping section junction with the first Vacuum shaping section junction more gradually.The vacuum sizing cover of the utility model, through three stage structure design cleverly, the moulding pipe of heat carries out pre-cooled in the first Vacuum shaping section; Get into the second Vacuum shaping section rapidly; The pipe of heat tightly is adsorbed under vacuum action on the calibration sleeve inside pipe wall, and caliber has been accomplished the longitudinal stretching function of tubing by quadratic extension; Physicochemical property to tubing improves; After the tubing expansion was further cooled off, along with getting into the 3rd section Vacuum shaping section, tubing shrank and is cooled to required caliber; Tubing is fine and close more; This moment, tube surfaces fineness can further improve because vacuum and contraction are cooled off, and tubing and calibration sleeve inwall frictional force strengthen gradually.Through the vacuum sizing cover of the utility model, realized twice processing that expansion is earlier shunk again to pipe, improved the physicochemical property and the surface smoothness of tubing.
Further, the said first Vacuum shaping section internal diameter is identical with the 3rd Vacuum shaping section internal diameter.
Further, the first Vacuum shaping section of said sizing sleeve pipe, the second Vacuum shaping section and the 3rd Vacuum shaping section are formed in one.
Compared with prior art; The beneficial effect of the utility model technical scheme is: the vacuum sizing cover of the utility model; Through three stage structure design cleverly, realized twice processing that expansion is earlier shunk again to pipe, improved the physicochemical property and the surface smoothness of tubing.
Description of drawings
Fig. 1 is the vacuum sizing nested structure sketch map of prior art;
Fig. 2 is the vacuum sizing nested structure sketch map of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the technical scheme of the utility model is done further explanation.
As shown in Figure 2; Vacuum sizing nested structure sketch map for the utility model; Comprise sizing sleeve pipe 2 and the calibration sleeve fixture 1 that is connected sizing sleeve pipe 2 one ends; Sizing sleeve pipe 1 comprises the first Vacuum shaping section 21, the second Vacuum shaping section 22 and the 3rd Vacuum shaping section 23 that is connected successively from left to right, and said left end refers to calibration sleeve fixture 1 place end.The first Vacuum shaping section 21 and the 3rd Vacuum shaping section 23 inside are cylindrical cavity, and the first Vacuum shaping section internal diameter is identical with the 3rd Vacuum shaping section internal diameter.The second Vacuum shaping section 22 is the tubing expansion segment of arc-shaped transition, and its internal diameter is from dwindle to increasing gradually earlier with the 3rd Vacuum shaping section 23 junctions with the first Vacuum shaping section, 21 junctions more gradually.The first Vacuum shaping section of sizing sleeve pipe 1, the second Vacuum shaping section and the 3rd Vacuum shaping section are formed in one.
The excircle place of calibration sleeve fixture 1 is provided with installing hole 11, is used for calibration sleeve is installed to the tubing production equipment.
The operation principle of the utility model is: the first Vacuum shaping section 21 is pre-cooled section; The moulding pipe of heat carries out pre-cooled in the first Vacuum shaping section 21, get into the second Vacuum shaping section 22 rapidly, and the pipe of heat tightly is adsorbed on the calibration sleeve inside pipe wall under vacuum action; Caliber is by quadratic extension; Accomplished the longitudinal stretching function of tubing, the physicochemical property to tubing improves; After the tubing expansion was further cooled off, along with getting into the 3rd section Vacuum shaping section 23, tubing shrank and is cooled to required caliber; Tubing is fine and close more; This moment, tube surfaces fineness can further improve because vacuum and contraction are cooled off, and tubing and calibration sleeve inwall frictional force strengthen gradually.
