Description

Technical Field

[0001] This utility model relates to the field of suspension insulator production technology, and in particular to an automatic forming and spinning mechanism for suspension insulators. Background Technology

[0002] Suspension insulators are generally constructed by gluing insulating components (such as porcelain or glass components) and metal fittings (such as steel feet, iron caps, and flanges) together with adhesive or mechanically clamping them together. Insulators are widely used in power systems and are generally external insulators, operating under atmospheric conditions. Overhead transmission lines, busbars in power plants and substations, and the external energized conductors of various electrical equipment must be supported by insulators to insulate them from the ground (or grounded objects) or other conductors with a potential difference.

[0003] The production process of suspension insulators includes pressing clay into a rotary blank, transferring the rotary blank to a forming mold, pressing it into shape, and then glazing the surface of the formed suspension insulator blank. During the pressing process of the blank through the forming mold, how to improve the stability of the pressing process and ensure the quality of the product by improving the structure of the automatic forming and spinning mechanism of suspension insulators has become an urgent technical problem to be solved. Utility Model Content

[0004] The technical problem to be solved by this utility model is: how to improve the stability of pressing and forming and ensure the forming quality of the product by improving the structure of the automatic forming and spinning mechanism of suspension insulator.

The upper forming mold body is coaxially connected to the lower end of the rotating shaft, and the upper forming mold body is located directly above the lower forming mold body. The lifting seat is slidably connected to a pressure foot rod with a vertical axis via a guide sleeve at the outer position of the upper forming mold body. A buffer pad is connected to the lower end of the pressure foot rod, and a buffer spring is sleeved between the pressure foot rod and the guide sleeve and the buffer pad. In the free state, the height of the buffer pad is lower than the height of the lower end of the upper forming mold body. In the spinning working state, the buffer pad presses against the outer edge of the lower forming mold body.

[0006] Furthermore, in the above-mentioned automatic forming and spinning mechanism for suspension insulators, a through hole is provided at the central axis position of the lower forming mold body, and a limiting post is provided in the middle of the limiting groove to cooperate with the limiting hole. In the spinning working state, the lower forming mold body is limited and cooperated with the limiting groove, the limiting post is limited and cooperated with the through hole, and the upper end of the limiting post is flush with the bottom of the cavity.

[0007] Furthermore, in the above-mentioned automatic forming and spinning mechanism for suspension insulators, a cylindrical transition section is provided on the outer side of the lower forming mold body. In the spinning operation state, the cylindrical transition section is located above the lower mold support.

[0008] Furthermore, in the aforementioned automatic forming and spinning mechanism for suspension insulators, the lifting drive mechanism is a lead screw and guide rail assembly.

[0009] Furthermore, in the aforementioned automatic forming and spinning mechanism for suspension insulators, the rotary drive mechanism is a geared motor.

[0010] The beneficial effects of this utility model are as follows: the lower forming mold body and the lower mold support are connected by a separate limiting fit, which facilitates the flow of the suspension insulator blank supported by the lower forming mold body between different work stations. The upper forming mold body is connected to the lifting seat via a rotating shaft, and the upper forming mold body is connected to the lower end of the rotating shaft. The descent of the lifting seat and the rotation of the rotating shaft enable the upper forming mold body and the lower forming mold body to cooperate with each other to spin-form the suspension insulator blank. By setting the structure of the pressure foot rod and the buffer pad, when the lifting seat moves downward with the upper forming mold, the buffer pad presses against the outer edge of the lower forming mold body. Through the compression of the buffer spring, a stable pressing and limiting effect is formed between the lifting seat and the lower forming mold body, avoiding the shaking of the upper and lower molds during the spinning process, which would affect the spinning quality.

A rotary drive mechanism 7 is connected between the lifting seat 4 and the rotating shaft 6, and is used to drive the rotating shaft 6 to rotate. The upper forming mold body 8 is coaxially connected to the lower end of the rotating shaft 6, and the upper forming mold body 8 is located directly above the lower forming mold body 2. The lifting seat 4 is slidably connected to the outer side of the upper forming mold body 8 via a guide sleeve, and a pressure foot rod 41 with the axial direction in the vertical direction is connected to the lower end of the pressure foot rod 41. A buffer pad 42 is connected to the lower end of the pressure foot rod 41. A buffer spring 43 is sleeved between the pressure foot rod 41 and the guide sleeve and the buffer pad 42. In the free state, the height of the buffer pad 42 is lower than the height of the lower end of the upper forming mold body 8. In the spinning working state, the buffer pad 42 presses against the outer extension 24 of the lower forming mold body 2.

[0014] In the above embodiments, the lower forming mold body 2 and the lower mold support 3 are connected by a separate limiting fit, which facilitates the flow of the suspension insulator blank supported by the lower forming mold body 2 between different work stations. The upper forming mold body 8 is connected to the upper forming mold body 4 through the lifting seat 4. The upper forming mold body 8 is connected to the upper forming mold body 2 through the descent of the lifting seat 4 and the rotation of the rotating shaft 6. The upper forming mold body 8 and the lower forming mold body 2 cooperate with each other to spin-form the suspension insulator blank. By setting the structure of the pressure foot rod 41 and the buffer pad 42, when the lifting seat 4 moves downward with the upper forming mold, the buffer pad 42 presses against the outer extension 24 of the lower forming mold body 2. Through the compression of the buffer spring 43, a stable pressing and limiting effect is formed between the lifting seat 4 and the lower forming mold body 2, so as to avoid the upper and lower molds shaking during the spinning process and affecting the spinning quality.

[0015] In a preferred embodiment, the lower forming mold body 2 has a through hole 22 at the central axis position, and a limiting post is provided in the middle of the limiting groove to limit and cooperate with the through hole 22.

[0017] In the above embodiments, the cooperation between the through hole 22 and the limiting post can serve as an auxiliary limiting structure between the lower forming mold body 2 and the lower mold support 3. On the other hand, when it is necessary to unload the lower forming mold body 2 and the blank separately using a clamp, the cylindrical transition section 23 can be clamped by the gripper first, and then lifted from the lower mold support 3. Then, the through hole 22 at the bottom of the lower forming mold can be adsorbed by the vacuum suction cup, and the suspension insulator blank can be adsorbed by negative pressure. Then, the lower forming mold body 2 is inverted and moved to the blank unloading station. The vacuum suction cup is released, so that the blank loses its adsorption effect and is unloaded at the unloading station. Then, the lower forming mold body 2 is transferred to the transfer conveying mechanism for subsequent spinning forming operations.
