no. 1 approach

[0042] The first embodiment of the present invention relates to elastic ball seat crimp installation tool, see figure 1 , including a bracket 1, the bracket 1 is divided into two areas, one of which is equipped with an extruding device for curling a thin-walled cylindrical part into an elastic ball seat 16, and the other area is equipped with a device for pushing the elastic ball seat 16 into the ball seat cylinder Pushing device within 17.

[0043] The working principle or working process of the elastic ball seat curling installation tool is as follows:

[0044] Curled elastic ball seat: see figure 2 , placing the thin-walled cylinder in the extrusion device, using the extrusion device to change the outer diameter of the thin-walled cylinder until the thin-walled cylinder is curled into an elastic ball seat 16, and the curling of the elastic ball seat 16 is completed;

[0045] Install the elastic ball seat: see image 3 First, press one end of the elastic ball seat 16 int...

no. 2 approach

[0049] This embodiment relates to elastic ball seat curling installation tooling, see figure 1 , including a bracket 1, the bracket 1 is divided into two areas, one of which is equipped with an extruding device for curling a thin-walled cylindrical part into an elastic ball seat 16, and the other area is equipped with a device for pushing the elastic ball seat 16 into the ball seat cylinder Pushing device within 17.

[0050]The function of the support 1 is to provide support for the extruding device and the pushing device so that they can be installed, so it can have various forms, but considering the convenience of operation and reducing the input cost, the following supports are preferred in this embodiment:

[0051] The support 1 includes a top plate 18 and a bottom plate 5 which are parallel and opposite up and down. Several columns 11 are evenly arranged between the two plates, and the top of each column 11 is fixed on the lower surface of the top plate 18. The end is af...

Abstract

The invention provides an elastic ball seat curling installation tool and a using method. The elastic ball seat curling installation tool comprises a support, the support is divided into two areas, one area is provided with an extrusion device used for curling a thin-walled cylinder part into an elastic ball seat, and the other area is provided with a pushing device used for pushing the elastic ball seat into a ball seat cylinder. The thin-walled cylinder part is extruded through the extrusion device, the outer diameter of the thin-walled cylinder part is changed till the thin-walled cylinderpart is curled into the elastic ball seat, meanwhile, the elastic ball seat can be completely pressed into the ball seat cylinder through the pushing device, namely, curling and installing of the elastic ball seat can be completed by one worker in the same tool, and convenience is brought to use. The elastic ball seat is extruded, curled and installed through a lead screw nut, other large equipment is not needed, more time and labor are saved for workers, and the tool is compact in structure, reasonable in layout, small in size and convenient to carry. The extrusion device and the pushing device can be used independently, can be used for curling the elastic ball seat and can also be suitable for curling other metal thin-wall open cylinder parts.

Description

technical field [0001] The technical field of oil and gas field development of the present invention particularly relates to an elastic ball seat crimping installation tool and a using method. Background technique [0002] The elastic ball seat is a kind of isolation tool used for staged fracturing in oil and gas fields. It realizes the ball seat by crimping a thin-walled cylinder with an opening into a fixed dispenser and releasing it into the ball seat cylinder at a specific place. function. [0003] However, the crimping installation of the ball seat requires a large force, which cannot be achieved by workers with bare hands, and there are no ready-made frocks and tools that can realize the crimping installation at present. Contents of the invention [0004] The purpose of the embodiments of the present invention is to provide an elastic ball seat curl installation tool and a use method to overcome the above-mentioned technical defects. [0005] In order to solve the ...
