Abstract

The invention discloses a special-shaped hose vulcanization process and a device free of head cutting. After a hose blank of a hose is sleeved to a core mould, an end portion outer sleeve corresponding to the outer diameter of the hose blank is adopted to penetrate through the core mould, and two end heads of the hose blank are wrapped up. After the end portion outer sleeve is located on the core mould, vulcanization is conducted according to a conventional process, and the end portion outer sleeve is dismantled after vulcanization is finished. Therefore, sizes of two end portions of a vulcanized special-shaped hose are led to be stable, quality defects such as end portion horn mouths, end portion delaminating and end portion unevenness do not exist, sizes of batch products can be ensured to be in conformity, and additionally, a head cutting process after vulcanization of a special-shaped hose can be removed. Loss of the hose blank is greatly reduced, comprehensive economic benefits are improved, and cost is lowered by approximately 15%. The special-shaped hose vulcanization process and the device free of head cutting are simple in method and easy to achieve. The adopted device is simple in structure, easy to manufacture, low in cost and good in using effect.

Description

Exempt from special-shaped flexible pipe sulfuration process of crop and device
Technical field
The present invention relates to a kind of sulfuration process and device of tubing, especially a kind of special-shaped flexible pipe sulfuration process of crop of exempting from.
Background technology
At present, special-shaped flexible pipe is the straight tube state before sulfuration, after the sulfuration of cover core, depoling, promptly accomplishes typing, and flexible pipe has become desired various shaped flexible by straight tube.But the shaped flexible both ends are in cover core process; Because both ends receive repeatedly bending, stretch, push the iso-stress effect, therefore, after sulfuration; Various mass defects very easily appear in the two ends of flexible pipe, such as horn mouth, end delamination, inside/outside diameter size is bigger than normal, the tip lengths size is inconsistent etc.For overcoming above mass defect, the way of taking increases semi-finished product length often, after sulfuration typing depoling; Flexible pipe is inserted in cutting die; To flexible pipe both ends crop, possibly defective part cut, could guarantee flexible pipe both ends quality like this; The tube head that downcuts generally will have 2~3cm, and 4~6cm has added up at two ends.As hose length be 50cm then crop loss reach about 10%, caused great waste.
Summary of the invention
The objective of the invention is: a kind of special-shaped flexible pipe sulfuration process of crop and device of exempting from is provided, and it can guarantee the steady quality of two ends after sulfuration of shaped flexible, and need not crop processing, has reduced the loss of pipe embryo, to overcome the deficiency of prior art.
The present invention is achieved in that and exempts from the special-shaped flexible pipe sulfuration process of crop; After the pipe embryo of flexible pipe is inserted in core, adopts with managing the corresponding end overcoat of embryo outside dimension and pass core, and two terminations will managing embryo encase; After being enclosed within on the core location outside the end; Vulcanize by common process, sulfuration is accomplished the back and is removed the end overcoat, will manage embryo and pull up and promptly obtain exempting from crop abnormal shape flexible pipe.
The end overcoat of special-shaped flexible pipe comprises body, and the leading portion of body is a flexible tube section, and the back segment of body is the core section, and flexible tube section is communicated with the core section, is positioning port at the link position place of flexible tube section and core section.
Body is the silicon rubber body.Body can adopt metal material, also can adopt nonmetallic materials.But when adopting silicon rubber to make,, be convenient to hose and pack into, extract,, when vulcanizing simultaneously, under steam pressure, hose is had the tight power of certain reed, make the hose better quality the flexible pipe not damaged because silicon rubber has certain elasticity.Silicon rubber is high temperature resistant, can long-term work under 250 ℃ of temperature (150 ℃ of flexible pipe curing temperatures), and body still can use for 500 times through using repeatedly.
Owing to adopted technique scheme, compared with prior art, vulcanize the flexible pipe termination that the present invention adopts the end overcoat to encase and is inserted in core; Can make the both ends dimensionally stable of the special-shaped flexible pipe that vulcanizates like this, mass defects such as no end horn mouth, end delamination, end out-of-flatness can guarantee the bulk article consistent size; And can remove the crop technology after the special-shaped flexible pipe sulfuration from; Reduce the loss of pipe embryo greatly, overall economic efficiency improves, and can reduce cost about 15%.Method of the present invention is simple, implements easily, and the apparatus structure that is adopted is simple, and is easy to make, with low cost, and result of use is good.
Description of drawings
Accompanying drawing 1 is a structural representation of the present invention;
Accompanying drawing 2 is a use sketch map of the present invention.
The specific embodiment
Embodiments of the invention: the structure of the end overcoat of special-shaped flexible pipe is as shown in Figure 1; Adopt silicon rubber to make body 1; External diameter according to pipe embryo 5 is produced corresponding flexible tube section 2 on body 1; According to the external diameter of core 6 is produced corresponding core section 3 on body 1, flexible tube section 2 is communicated with core section 3 again, is positioning port 4 at the link position place of flexible tube section 2 and core section 3.
Exempt from the special-shaped flexible pipe sulfuration process of crop, the pipe embryo 5 of flexible pipe is inserted in core 6 after, respectively two bodies 1 are passed core 6 from two ends; And two terminations will managing embryo 5 encase, and pipe embryo 5 is in the flexible tube section 2 of body 1, and the termination of pipe embryo 5 contact with positioning port 4; Length according to pipe embryo 5 positions body 1 on core 6; Vulcanize by common process then, remove body 1 after sulfuration is accomplished, pipe embryo 5 is pulled up the special-shaped flexible pipe that promptly obtains exempting from crop.

Claims (3)

1. exempt from the special-shaped flexible pipe sulfuration process of crop for one kind; It is characterized in that: after the pipe embryo of flexible pipe is inserted in core, adopts with managing the corresponding end overcoat of embryo outside dimension and pass core, and two terminations will managing embryo encase; After being enclosed within on the core location outside the end; Vulcanize by common process, sulfuration is accomplished the back and is removed the end overcoat, will manage embryo and pull up and promptly obtain exempting from crop abnormal shape flexible pipe.
