Description

High-precision extrusion die head

Technical Field

The utility model relates to the technical field of extruders, in particular to a high-precision extrusion die head.

Background

Extruders are one of the classes of plastic machinery, originating in the 18 th century. The extruder can divide the machine head into a right-angle machine head, an oblique-angle machine head and the like according to the material flow direction of the machine head and the included angle of the central line of the screw rod. The screw extruder relies on pressure and shearing force generated by screw rotation, so that materials can be fully plasticized and uniformly mixed, and the materials are molded through a die. Plastic extruders can be classified basically into twin-screw extruders, single-screw extruders and less common multi-screw extruders and screw-less extruders.

Extrusion dies are one type of forming die, except that the way in which they are discharged is by extrusion. The aluminum alloy is widely applied to aluminum special-shaped structures and also used in plastic parts. The extruder is used for making pipes or profiles at the front end of the extruder. In short, a mold is a tool for molding an article, which is composed of various parts, and a different mold is composed of different parts, which realizes the processing of the outer shape of the article mainly by changing the physical state of the molded material.

After the wire body is manufactured, the thickness of the wire body may need to be further manufactured, and the wire body is extruded through a wire extruder in the prior art, but the wire extruder has higher cost, the diameter needs to be gradually reduced in the extrusion process, and the extrusion die head is easy to be blocked without being gradually reduced.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 1 and 2, a high-precision extrusion die head comprises a die body 5, an inlet 6 and an outlet 7 are respectively arranged on two sides of the die body 5, the center heights of the inlet 6 and the outlet 7 are the same, when a wire harness enters from the inlet 6, the discharging process from the outlet 7 is in a horizontal state, the straightness of the wire harness cannot be damaged, a rotating head 9 is arranged between the inlet 6 and the outlet 7, the rotating head 9 is connected with an output shaft of a driving motor 1, a follow-up extrusion assembly is arranged above the rotating head 9, the wire harness is driven to advance through the rotation of the rotating head 9, and the diameter of the wire harness is reduced in the advancing process.

The extrusion subassembly includes regulating block 4, the one end and the die body 5 swing joint of regulating block 4, the other end are provided with the notch, and swing joint adjusts the bolt 2 setting on the die body 5 in the notch of regulating block 4 to through the nut restriction, the bottom of regulating block 4 is provided with follower head 10 and rotates the head 9 laminating, after the wire harness gets into from import 6, passes between rotating head 9 and the follower head 10, because regulating block 4 has been restricted by the nut, so regulating head 4 can not be jacked up by the wire harness, has guaranteed the diameter identity of wire harness.

The both sides limit of rotating head 9 is provided with the dogtooth, and the dogtooth meshes with the recess on follower 10 both sides, rotating head 9 wheel body surface and follower 10 wheel body surface are provided with the arc recess, in order to guarantee that rotating head 9 can effectually drive follower 10, increase the dogtooth on rotating head 9, then mesh with the recess of follower 10 through the dogtooth and increase the driving force, even meet the thicker metal wire harness of diameter like this, rotating head 9 also can not skid.
