Description

Technical Field

[0001] The utility model relates to the field related to hydraulic pipe joints, and in particular to a hydraulic pipe joint thermoforming auxiliary die. Background Art

[0002] Hydraulic pipe fittings are crucial connection components in hydraulic systems. They are responsible for accurately and firmly connecting various hydraulic components such as pipes, valves, pumps and actuators, ensuring that the hydraulic medium (such as hydraulic oil) can smoothly and efficiently transmit power and signals throughout the system. When the pipe fittings do not have a connection device at the joint end, they need to be assisted by external thermoforming equipment.

[0003] The prior art with patent publication (announcement) number CN218505252U discloses a hydraulic pipe joint thermoforming auxiliary mold, including a bottom assembly seat and an electric heating plate, the upper end of the bottom assembly seat is provided with an arc-shaped left-placed assembly groove and an arc-shaped right-placed assembly groove, the upper end of the bottom assembly seat is located between the arc-shaped left-placed assembly groove and the arc-shaped right-placed assembly groove and is provided with a bottom telescopic groove with a built-in lifting copper heat-conducting ring, the bottom surface of the arc-shaped left-placed assembly groove and the arc-shaped right-placed assembly groove is provided with a bottom transmission groove for internally movably assembling a translation screw, the electric heating plate is fixedly installed inside the lifting copper heat-conducting ring, the arc-shaped left-placed assembly groove and the arc-shaped right-placed assembly groove are internally slidably equipped with a pipe assembly clamp controlled by a translation screw, and the bottom assembly seat is internally movably equipped with a first lateral control handle for controlling the rotation of the translation screw and a second lateral control handle for the lifting copper heat-conducting ring.

[0004] The aforementioned patent document discloses an auxiliary thermoforming die for hydraulic pipe joints. While this solves the problem that conventional thermoforming equipment, which simply heats and softens a single surface and then manually squeezes to form connections, can cause uneven force to cause the connection position to deviate, seriously affecting the sealing and durability of the connection, it has the disadvantage that it can only fix pipes of the same model when fixing the pipe structure. When facing pipes of different models or sizes, the entire set of fixing devices must be replaced or additional adaptation measures must be taken, thereby increasing the complexity and cost of installation and maintenance.

[0005] Therefore, we make improvements to this problem and propose a hydraulic pipe joint thermoforming auxiliary mold. Utility Model Content

[0034] In order to solve the technical problems in the background technology, the following auxiliary mold for thermoforming of hydraulic pipe joints is provided:

[0035] Combine Figure 1 - Figure 5As shown, the utility model provides a hydraulic pipe joint thermoforming auxiliary mold, including a base 1, two movable frames 2 are arranged on the upper surface of the base 1, and the inside of the two movable frames 2 are provided with a clamping mechanism 3, a movable mechanism 4 is provided between the two movable frames 2 and the base 1, and a heating ring 5 is provided on the upper side of the base 1, and a connecting mechanism 6 is provided between the heating ring 5 and the base 1; the clamping mechanism 3 includes a connecting groove 301, and the connecting groove 301 is opened on the inner walls on both sides of the movable frame 2, the inside of the connecting groove 301 is slidably connected with a first sliding plate 302 and a second sliding plate 303, and the lower surface of the first sliding plate 302 and the upper surface of the second sliding plate 303 are fixedly installed with two fixing frames 304, and the inside of the fixing frame 304 is rotatably connected with a roller 305.

[0036] In this embodiment, two flexibly movable frames 2 are provided on the upper surface of the base 1. Clamping mechanisms 3 are provided inside the two movable frames 2 to accommodate and secure pipes of different sizes. The clamping mechanisms 3 are designed with internal connecting grooves 301, which can smoothly slide and accommodate a first sliding plate 302 and a second sliding plate 303. Four fixing brackets 304 are fixedly mounted on the upper and lower surfaces of the two sliding plates, respectively. Each fixing bracket 304 is equipped with a freely rotatable roller 305. This not only ensures the stability of the pipe during the clamping process, but also greatly reduces friction damage to the pipe surface, thereby improving the applicability and durability of the mold.

[0037] After the two pipes to be thermoformed are clamped in the movable frames 2 on both sides, the surfaces of the pipes on both sides can be heat-treated by starting the heating ring 5. Then, the movable frames 2 on both sides can be moved by the movable mechanism 4 to thermoform the two heat-treated pipes.

The gear 409 is engaged with the first rack 404 and the second rack 406 to ensure that when the rotating rod 408 rotates, it can drive the two moving frames 2 to move synchronously and smoothly. By installing a rotating handle 410 at one end of the rotating rod 408, the position of the moving frame 2 can be controlled by simply rotating the rotating handle 410, and the pipes on both sides can be thermoformed.

[0051] In addition, by fixing the limit block 407 inside the groove 402, it is slidably connected to the first rack 404, effectively limiting the first rack 404 to avoid tilting, thereby ensuring the reliability and safety of the entire driving process.
