Description
Technical Field
The invention relates to the field of pouring, in particular to an expansion section winding core mold.
Background
The glass fiber is used as a structure for wrapping the cylinder body, can effectively insulate heat, and is widely applied to the production of various industries at present; however, the glass fiber covering of the tapered expanding section is difficult to process, so that it is necessary to provide an expanding section winding core mold which is easy to process and easily demolded.
Disclosure of Invention
The invention aims to provide an expansion section winding core mould, which solves the technical problems.
In order to achieve the technical purpose and achieve the technical requirements, the invention adopts the technical scheme that: an expansion segment winding mandrel, characterized in that: comprises a rotating section, a winding section and a fixing section; the rotating section is provided with a mandrel hole and a mandrel fixing hole, and the mandrel fixing holes are uniformly arranged around the mandrel hole; the winding section is of a conical structure, and a reinforcing partition plate is arranged in the winding section; the fixing section is provided with a fixing shaft hole, a positioning hole and a baffle fixing hole, the positioning hole is uniformly arranged around the fixing shaft hole, and the baffle fixing hole is uniformly arranged at the end part of the fixing section.
As a preferred technical scheme: the rotating section and the winding section are integrally formed, and the reinforcing partition plate and the fixing section are fixed on the winding section through welding.
As a preferred technical scheme: the fixed section and the reinforcing partition plate are of a circular structure, and a plurality of through holes are formed in the fixed section and the reinforcing partition plate.
The winding device is simple in structure, and the product quality is ensured without radial deviation and shaking in the winding process; and the strength of the die is improved, and the service life is prolonged.

Detailed Description
An expansion segment winding mandrel, characterized in that: comprises a rotating section 1, a winding section 2 and a fixing section 3; the rotating section 1 is provided with a mandrel hole 4 and a mandrel fixing hole 5, and the mandrel fixing hole 5 is uniformly arranged around the mandrel hole 4; the winding section 2 is of a conical structure, and a reinforcing partition plate 6 is arranged in the winding section 2; the fixing section 3 is provided with a fixing shaft hole 7, a positioning hole 8 and a baffle fixing hole 9, the positioning hole 8 is uniformly arranged around the fixing shaft hole 7, and the baffle fixing hole 9 is uniformly arranged at the end part of the fixing section 3.
The rotating section 1 and the winding section 2 are integrally formed, and the reinforcing partition plate 6 and the fixing section 3 are fixed on the winding section 2 through welding. The fixed section 3 and the reinforcing partition plate 6 are of a circular structure, and a plurality of through holes are formed in the fixed section 3 and the reinforcing partition plate 6.
In the specific implementation:
firstly, integrally forming a support for a rotating section and a winding section, and then welding a reinforcing partition plate and a fixing section at corresponding positions of the winding section; the reinforcing partition plate plays a role of reinforcing ribs, and meanwhile, a plurality of round holes are formed in the reinforcing partition plate, so that the weight is reduced, and the cost is saved; the fixing section is also provided with a through hole, so that the cost is saved as much as possible on the premise of not influencing the strength; when the device is used, the rotating section is fixed with the mandrel through the mandrel hole and the mandrel fixing hole, and then the fixing section is matched with the fixing shaft hole through the positioning hole and the fixing shaft hole; starting the winding device, driving the mandrel by the motor, driving the rotating section to rotate by the mandrel, and simultaneously rotating the rest parts; and the positioning hole and the fixing shaft hole of the fixing section ensure that radial deviation and shaking are not generated in the winding process.
