The purpose is to provide an aluminum-plastic composite tape forming and sizing die, which can ensure that the aluminum-plastic composite tape can not be broken under the condition that the size of a cable core fluctuates, so that the product percent of pass is improved, and the production cost of an enterprise is reduced. The technical scheme is as follows: a sizing die for forming an aluminum-plastic composite belt comprises a die main body in the shape of a rotary body, a conical output cylinder and a conical flow passage, wherein the die main body is composed of a cylindrical base body, the conical output cylinder is connected with the base body, and the conical flow passage is coaxially arranged with the die main body; the method is characterized in that: the conical output cylinder is provided with a plurality of expansion joints, and the expansion joints are radially arranged on the axis of the conical output cylinder and penetrate through the cylinder wall and the outlet end of the conical output cylinder.
Description
Technical Field
The utility model relates to a mould is made to the optical cable, specifically is compound tape forming sizing mould of plastic-aluminum.
Background
When the existing outdoor GYTA type optical cable sheath is produced, the adopted aluminum-plastic composite tape sizing die mostly adopts a sizing die with a single size type. In the actual production process, the difference between the tensile strength of the aluminum-plastic composite belt and the steel-plastic composite belt is large; when the diameter of the cable core changes greatly, the aluminum-plastic composite belt is easy to break, although the larger degree of the cable core is within the tolerance of the required range. This phenomenon is always puzzling the technicians in the industry, and each time the aluminum-plastic composite belt is broken, the large economic loss is directly caused, and the phenomenon also becomes a persistent problem to be solved by the manufacturing enterprises.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that overcome above-mentioned background art not enough, provide a compound tape forming sizing mould of aluminium-plastic, this mould should be able to exist under the undulant condition of size at the cable core, and the compound tape of aluminium-plastic still can not be taken absolutely to improve the qualification rate of product, reduce the manufacturing cost of enterprise.
The utility model adopts the technical proposal that:
a sizing die for forming an aluminum-plastic composite belt comprises a die main body in the shape of a rotary body, a conical output cylinder and a conical flow passage, wherein the die main body is composed of a cylindrical base body, the conical output cylinder is connected with the base body, and the conical flow passage is coaxially arranged with the die main body; the method is characterized in that: the conical output cylinder is provided with a plurality of expansion joints, and the expansion joints are radially arranged on the axis of the conical output cylinder and penetrate through the cylinder wall and the outlet end of the conical output cylinder.
The angles between every two expansion joints are equal.
The width of the expansion joint is 0.08-0.2 mm.
The length of the expansion joint is 10-20 mm.
The diameter of the conical flow channel is uniformly changed from large to small from the base body to the conical output cylinder.
The beneficial effects of the utility model reside in that: the utility model provides an aluminum-plastic composite tape shaping sizing die, can reduce the resistance when the cable core sizing shaping effectively when GYTA type optical cable is produced, guaranteed that the cable core has under the condition that the size fluctuates, the aluminum-plastic composite tape still can not break the area; not only can ensure the product quality and reduce the production cost, but also has simple device structure and no increase of the production operation workload, and is suitable for popularization and application.

Fig. 2 is a right-view structural schematic diagram of the sizing die for forming the aluminum-plastic composite belt.
Fig. 3 is an enlarged schematic view of a portion a in fig. 2.
Detailed Description
The following further description is made with reference to the embodiments shown in the drawings.
The aluminum-plastic composite tape forming and sizing die shown in the attached drawing is characterized in that a die main body in the shape of a rotary body consists of a cylindrical base body 1, a conical output cylinder 3 connected with the base body and a conical flow passage 2 coaxially arranged with the die main body, and the diameter of the conical flow passage is uniformly changed from large to small in the direction from the base body to the conical output cylinder (namely, the left-to-right direction in the drawing 1). The structure is the same as the existing sizing die for forming the aluminum-plastic composite belt.
The utility model discloses an improvement is: the tapered output cylinder is provided with a plurality of expansion joints 4, and the expansion joints are radially arranged on the axis of the tapered output cylinder and penetrate through the cylinder wall (namely, penetrate through the tapered output cylinder in the radial direction) and the outlet end (as shown in fig. 1, the expansion joints penetrate through the outlet end of the tapered output cylinder in the axial direction of the tapered output cylinder). Preferably, the expansion joints are six.
Furthermore, the angles between every two expansion joints are equal.
Further, the width of the expansion joint is 0.08-0.2 mm.
Further, the length of the expansion joint is 10-20 mm; or selected as desired.
The utility model discloses a theory of operation is: when the utility model works, when the diameter of the cable core changes greatly, the expansion force (the expansion force applied by the aluminum-plastic composite belt coated outside the cable core) applied to the conical output cylinder in the outer diameter direction increases suddenly; when the expansion force reaches a certain value, the outlet part of the conical output cylinder is retracted towards the outer diameter direction, so that the expansion joint is enlarged, the tension force applied to the aluminum-plastic composite belt is not increased any more, and the belt breakage phenomenon of the aluminum-plastic composite belt is eliminated.
The above is a detailed introduction of the sizing die for forming the aluminum-plastic composite belt provided by the utility model; for general manufacturers in the field, according to the ideas and principles of the embodiments of the present invention, there are changes in the specific implementation and application range; accordingly, the contents of this specification should not be construed as limiting the invention.
