Description

Technical Field

[0001] This utility model relates to the technical field of flaring devices, specifically a flaring device for the production of LNG stainless steel pipe fittings. Background Technology

[0002] This utility model relates to the technical field of LNG stainless steel pipe fitting production equipment, and in particular to a flaring device for LNG stainless steel pipe fitting production. Flaring is one of the key steps in the LNG stainless steel pipe fitting production process.

[0003] Currently, some devices exist on the market for flaring stainless steel pipe fittings, but these devices have some problems in practical applications. For example, some flaring devices lack clamping stability, causing the pipe fittings to wobble during the flaring process, resulting in low flaring accuracy and affecting product quality. Other flaring devices have inflexible flaring head adjustments, failing to meet the flaring requirements of different specifications of stainless steel pipe fittings, necessitating frequent flaring head replacements, which increases production time and costs. Therefore, developing a flaring device for LNG stainless steel pipe fitting production that offers stable clamping, flexible flaring head adjustment, easy operation, and low cost is of significant practical importance. Utility Model Content

[0004] The purpose of this utility model is to provide a flaring device for the production of LNG stainless steel pipe fittings, which solves the technical problems of unstable pipe clamping, insufficient flaring accuracy, and difficulty in adapting to multiple specifications of pipe fittings in existing flaring devices, and achieves the purpose of realizing rapid mold change, stable clamping of pipe fittings, and flexible adaptation to the production of LNG stainless steel pipe fittings of different specifications.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flaring device for the production of LNG stainless steel pipe fittings, comprising a support platform, a pipe fitting clamping top, and a movable adjusting flaring part. The bottom outer wall of the support platform is symmetrically and fixedly equipped with support legs, and the bottom outer wall of the support legs is fixedly equipped with support pads. The pipe fitting clamping top is located at the top of the support platform. The movable adjusting flaring part is located on the top outer wall of the support platform.

[0006] Preferably, the top of the pipe clamping device specifically includes: a fixed support plate, fixedly installed on the top outer wall of the support platform; a three-jaw pneumatic chuck, disposed on the top outer wall of the support platform; a support fixing rod, symmetrically fixedly installed on the top outer wall of the support platform; a support clamping block, fixedly installed on the top outer wall of the support platform; guide grooves, symmetrically formed on the top outer wall of the support platform; and a movable groove, formed on the top outer wall of the support platform.

[0007] Preferably, the inner wall of the fixed support plate has an opening, the three-jaw pneumatic chuck is fixedly installed inside the opening, the interior of the three-jaw pneumatic chuck is provided with a stainless steel pipe fitting, the top outer wall of the support fixing rod is fixedly installed with a support top plate, and the bottom outer wall of the support top plate is symmetrically fixedly installed with guide slide rods.

[0008] Equipped with a three-jaw pneumatic chuck, this chuck can quickly clamp pipe fittings using air pressure, significantly reducing clamping time compared to manual clamping. It also provides uniform and stable clamping force, preventing pipe misalignment during flaring due to uneven force. Combined with an auxiliary clamping block driven by an electric telescopic rod, it enables multi-directional fixing of the pipe fitting, effectively resisting reaction forces during flaring and ensuring processing stability. In terms of precise positioning and adaptability, the three-jaw pneumatic chuck's built-in centering function ensures accurate alignment between the pipe fitting's centerline and the flaring head's axis, improving flaring concentricity. Combined with a moving adjustment mechanism, it can flexibly adapt to pipe fittings of different diameters, eliminating the need for frequent clamp changes, thus ensuring flaring accuracy and improving equipment versatility.

[0009] Preferably, the other end of the guide slide rod is fixedly connected to the top outer wall of the support clamping block, a fixing frame is fixedly installed on the top outer wall of the support top plate, an electric telescopic rod is fixedly installed inside the fixing frame, and the telescopic end of the electric telescopic rod movably passes through the top outer wall of the support top plate and extends to the bottom outer wall of the support top plate.

[0010] An electric telescopic rod is installed, which can control the extension and retraction stroke. Working in conjunction with a three-jaw pneumatic chuck, it achieves synchronous and stable clamping of both ends of the pipe fitting. This multi-point clamping method effectively avoids swaying or displacement of the pipe fitting during flaring due to uneven force, ensuring the accuracy of the flaring position and improving processing precision. In terms of efficient and flexible adjustment, the electric telescopic rod can quickly respond to control commands, flexibly adjusting the clamping height and force according to pipe fittings of different lengths and specifications. Compared to traditional mechanical adjustment structures, frequent manual calibration is unnecessary, significantly shortening pipe fitting clamping time, improving the equipment's adaptability to diverse production needs, and enhancing production efficiency.

[0015] An installation flange plate is provided, featuring a standard interface design. Connected to the mounting plate via fixing bolts, it allows for quick disassembly and replacement of flaring heads of different specifications. This modular installation method adapts to the flaring requirements of various pipe diameters without complex adjustments, significantly improving the equipment's versatility and production efficiency. The rigid connection between the installation flange plate and the connecting rod ensures stable transmission of the rotating motor's torque to the flaring head, preventing processing deviations caused by loose connections during the flaring process. Simultaneously, the circumferentially spaced fixing bolts further enhance the connection strength between the mounting plate and the flange plate, ensuring the flaring head remains stable during high-pressure flaring operations, guaranteeing processing accuracy and equipment operational safety.

[0016] Preferably, the outer wall of the other side of the mounting flange is provided with a mounting plate, and the mounting plate is provided with mounting openings equidistantly around its circumference.

Supporting and fixing legs 2 are symmetrically fixedly installed on the bottom outer wall of the support platform 1, and supporting pads are fixedly installed on the bottom outer wall of the supporting and fixing legs 2. The pipe fitting clamping top 3 is located on the top of the support platform 1. The movable and adjustable flaring part 4 is located on the top outer wall of the support platform 1.

[0028] The pipe clamping top 3 specifically includes: a fixed support plate 313, which is fixedly installed on the top outer wall of the support platform 1; a three-jaw pneumatic chuck 311, which is set on the top outer wall of the support platform 1; a support fixing rod 316, which is symmetrically fixedly installed on the top outer wall of the support platform 1; a support clamping block 317, which is fixedly installed on the top outer wall of the support platform 1; a guide slide 314, which is symmetrically opened on the top outer wall of the support platform 1; and a movable slide 315, which is opened on the top outer wall of the support platform 1.

[0038] Working principle: When using:

[0039] Step 1: Level and fix the support platform 1 using the support pads at the bottom of the support legs 2 to ensure equipment stability. Preset the specifications of the pipe fittings to be processed in the control system, including pipe diameter, flaring depth and flaring head model 4114, and complete the equipment initialization.

[0040] Step 2: Place the stainless steel pipe fitting 312 to be processed in the center of the three-jaw pneumatic chuck 311, start the pneumatic system, and the three-jaw pneumatic chuck 311 tightens and fixes the pipe fitting.
