Description

TECHNICAL FIELD

[0001] The utility model relates to hydraulic pipe processing field especially relates to a kind of hydraulic pipe buckling auxiliary regular device and buckling mechanism. BACKGROUND

[0002] In the processing of hydraulic pipe, buckling operation is a very key link, which is directly related to the connection sealing and overall performance of hydraulic pipe. However, the current hydraulic pipe faces a significant problem when buckling, as follows:

[0003] As shown in Figure 1 and Figure 2 , for example, the structure of the 45° joint hydraulic pipe 8 is usually composed of a joint part 81 and a hose part 82. During actual production and handling, etc., since the joint part 81 and the hose part 82 are only preliminarily connected at this time, i.e., not completely fixed, under the action of gravity and other external forces, the joint part 81 and the hose part 82 are prone to relative deflection. This relative deflection can cause the bending directions of the joint part 81 and the hose part 82 to be inconsistent (as shown in Figure 2 ).

[0004] If buckling operation is performed in the above state, the joint part 81 and the hose part 82 will be forcibly fixed together. However, in actual application scenarios, according to the use requirements and installation layout, the joint part 81 often needs to be rotated and adjusted in the opposite direction of its own bending direction around the hose part 82 (as shown by the arrow direction in Figure 2 ) to adapt to the corresponding connection requirements. However, since the joint part 81 and the hose part 82 are fixed during buckling, this rotation adjustment will generate uncertain twisting and rotational pulling stress between the joint part 81 and the hose part 82. These stresses not only reduce the overall structural strength of the hydraulic pipe 8, but also can affect the internal hydraulic transmission stability of the hydraulic pipe 8, such as causing a decrease in sealing performance, a risk of leakage, and even accelerating the wear and aging of the hydraulic pipe 8 during long-term use, greatly shortening its service life and seriously affecting the effectiveness and reliability of the hydraulic pipe 8 in actual application.

It should be noted that the drawings are all very simplified and use non-precise scales, and are only used to facilitate and clarify the purpose of assisting in the description of the utility model embodiments.

[0032] Embodiment one

[0033] As shown in Figure 3 and Figure 4 The utility model discloses an auxiliary regular device is buckled to hydraulic pipe, including frame 1, rotary drive 2, rely on the block 3 and the positioning block 4.

[0034] Among them, rotary drive 2 sets up on frame 1, is used to provide the output power of the rotation of relying on the block 3.

[0035] Specifically, the block 3 is fixedly installed on the rotary drive 2 deviated from the position of the center, for receiving and driving the joint part of hydraulic pipe rotates around the hose part axis center line direction.

[0036] Need to be specially pointed out is, the hose part axis center direction of hydraulic pipe and the rotation center point of rotary drive 2 are located in the same horizontal plane, ensure that the block 3 in the process of driving the joint part moves, can make the joint part rotates relative to the hose part, also will not form the rotation stress to the hose part, guarantee the forming quality of subsequent hydraulic pipe.

[0037] In addition, the positioning block 4 is fixedly installed on the frame 1, and is located on the outside of the rotary drive 2, for cooperating with the block 3, to complete the positioning of the joint part of hydraulic pipe before buckling, improves the forming quality of hydraulic pipe.

[0038] Specifically, when the rotary drive 2 drives, can drive the block 3 to rotate to the surface parallel of the positioning block 4, make the block 3 and the positioning block 4 between around form a positioning chamber that clamps the joint part of hydraulic pipe, to guarantee that the joint part does not appear loose when buckling with the hose part to form hydraulic pipe, improves the forming effect.

[0039] The device is provided with the rotating driving member 2, the abutting block 3 and the positioning block 4, the abutting block 3 can receive the joint part of the hydraulic pipe and drive the joint part to rotate around the axis of the hose part, and the abutting block 3 can also rotate to form a positioning chamber with the positioning block 4 to clamp the joint part of the hydraulic pipe, so that when the joint part is buckled with the hose part to form the hydraulic pipe, the joint part and the hose part can always maintain a certain posture, so as to avoid buckling combination of the joint part and the hose part in the state of relative deflection, and to avoid the occurrence of uncertain distortion and rotational pulling stress between the two in the subsequent application process, so as to improve the quality and application performance of the formed hydraulic pipe.

[0040] It should be further pointed out that in the prior art, the model of the hydraulic pipe can be mainly divided into 45° joint hydraulic pipe and 90° joint hydraulic pipe, the main difference between which is the included angle formed between the joint part and the hose part, and accordingly the length of the hydraulic pipe is different, so in the embodiment, the length of the abutting block 3 can be increased to meet the application requirements of the above two types of hydraulic pipes, that is, without the need to replace special equipment, the purpose of stronger universality is achieved.

Accordingly, the joint part of the hydraulic pipe is exposed to the outside, i.e. for the straightening operation of the hydraulic pipe buckling auxiliary straightening device.

[0050] Specifically, the hydraulic pipe buckling auxiliary straightening device is used to drive the joint part of the hydraulic pipe to rotate around the axis of the hose part and keep relatively fixed.

[0051] It should be noted that the buckling device 6 is also provided with a buckling assembly for buckling operation after the joint part and the hose part form a specific posture, which is a prior art and thus will not be described here.

[0052] The device can quickly realize the straightening and buckling of the relative posture between the joint part and the hose part of the hydraulic pipe through the effective combination of the hydraulic pipe buckling auxiliary straightening device and the buckling device 6, and achieve the purpose of improving the quality and application performance of the formed hydraulic pipe.

[0053] It should be noted that the rack 1 is located on one side of the buckling device 6, and the output shaft center of the rotating driving member 2 and the center of the feeding port are located in the same horizontal plane, so that when the abutting block 3 rotates to drive the joint part to move, the joint part can rotate relative to the axis of the hose part to complete the straightening and adjusting function, and the hose part will not be subjected to rotational stress during the process, thereby ensuring the forming quality of the hydraulic pipe after buckling.
