Description

Technical Field

[0001] The invention relates to an insulating pull rod core mold rolled with polyester cloth and fiber cloth in the electric power industry, and in particular to an insulating pull rod core mold automatic assembly device and method. Background Art

[0002] At present, the production method of insulating rod core molds wound with polyester cloth and fiber cloth in the power industry is to manually wind the core mold blanks, and then manually push the core mold into the outer mold cavity. During the manual pushing of the core mold, the wrinkled cloth needs to be continuously stretched by hand little by little, and the cloth is smoothly attached to the core mold. Every time a section of the core mold is pushed into the outer mold cavity, the cloth needs to be manually stretched once until the entire core mold is completely entered into the outer mold cavity. During the assembly process, the skill level of each person is uneven, the quality of the product cannot be stable during the mass production process, and the production quality of the product requires high personal operating skills of the producer.

[0003] During manual operation, when the core mold is pushed into the outer mold, wrinkles will form on the outer layer of the core mold. When the wrinkles accumulate to a certain extent, the core mold cannot be loaded into the outer mold. At the same time, the wrinkles will cause product quality to be unqualified. Therefore, during the process of loading the core mold, the outer layer of the fabric must be continuously smoothed to facilitate the core mold to enter the outer mold cavity. This operation process requires high personal skills. The skill level of the operator directly affects the product quality. In addition, manual operation consumes a lot of physical energy and cannot quickly increase production. Currently, there is no relevant automated equipment in the industry that can assemble core molds.

8. A method for automatically assembling an insulating pull rod core mold, characterized in that: The automatic assembly device for insulating pull rod core mold according to any one of claims 1 to 7 comprises the following steps: When the equipment is in operation, the core mold (4) with the polyester cloth and the fiber cloth rolled up is placed in the V-groove tooling (14) in the lifting mechanism (1), the lifting cylinder (15) lifts up the V-groove tooling support plate (17), the core mold (4) with the polyester cloth and the fiber cloth rolled up is placed in the V-groove tooling (14), the lifting cylinder (15) retracts to its original position, and the core mold (4) with the polyester cloth and the fiber cloth rolled up and the inner hole of the insulating pull rod outer mold (7) are on the same axis, ready for assembly; Then, the three-phase asynchronous motor (10) in the core mold push rod mechanism (6) is rotated, and the motor drives the worm gear reducer (11) to rotate and drive the gear at the same time. The gear rotates on the rack (9), the driving mechanism moves, and the core mold push rod bracket (12) drives the core mold push rod (8) to move forward, pushing the core mold (4) rolled with polyester cloth and fiber cloth forward and loading it into the insulating pull rod outer mold (7). When the core mold (4) rolled with polyester cloth and fiber cloth is installed into the insulating pull rod outer mold (7), the head of the core mold first enters the hole of the insulating pull rod outer mold (7), and then the rotary pressing cylinder (21) in the core mold rotary pressing mechanism (2) is activated, driving the pressure head fixing plate (20) and the pressure head (19) to press on the nylon cloth on the outer layer of the core mold; After being fixed, the core mold cloth-smoothing mechanism (3) is activated, and the cloth-smoothing clamping cylinder (30) drives the cloth-smoothing tooling (31) to clamp the core mold. After clamping, the power wheel drives the servo motor (26) to rotate and drives the mechanism driving gear (32) to rotate. The mechanism driving gear (32) transmits power to the rotating large gear (37) through the idler wheel (28). The rotating large gear (37) rotates to drive the cloth-smoothing clamping cylinder (15) to rotate, and then drives the cloth-smoothing tooling (31) to rotate to spread the nylon cloth on the core mold through spiral rotation. At this time, the nylon cloth on the core mold is located between the two arc-shaped inner walls (13). While the rotating large gear (37) rotates, the module drives the servo motor (26) to rotate and drives the mechanism driving gear (32) to rotate. The motor (24) rotates, driving the linear module (25), and the linear module (25) drives the entire mechanism to move backward, achieving rotation and axial movement at the same time, which is divided into two actions. The first filter cloth is clamped by a 0.3Mpa cylinder, and after completion, the rear end is pressed by a clamping head. At this time, after a delay of 1 second, the clamping cylinder is switched to 0.6Mpa air pressure to reverse the previous filter cloth movement, and the clamping head is released at the beginning of the movement. The purpose of switching the atmospheric pressure is to push the cloth section that has been filtered in the first pass into the outer mold hole through the reverse direction filter cloth rotation + rear end propulsion force. After completion, the above actions are repeated until the entire core mold is pushed into the outer mold hole, and the nylon cloth outside the core mold is stretched; After completing the above actions, the rotary clamping cylinder (15) in the core mold rotary clamping mechanism (2) is activated, and the core mold is no longer pressed down. Then the core mold push rod mechanism (6) is assembled to push the core mold partly into the hole of the insulating pull rod outer mold (7) again, and the above actions are repeated, while the polyester cloth outside the core mold is stretched, the core mold is pushed until the entire core mold is pushed into the insulating pull rod outer mold (7); according to the above action equipment, the core mold (4) with rolled polyester cloth and fiber cloth in the industry can be automatically loaded into the mold and the cloth can be continuously stretched during the loading process.
