[0029] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0030] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0031] like Figure 1 , 2 As shown, a crimping machine is provided with a crimping mold 1, the crimping mold 1 includes a die core 11 and a die jacket 12, the die core 11 is installed on a fixed plate group 2, the die jacket 12 is rotatably installed on a movable plate group 3, a movable driving unit 4 is provided on the movable plate group 3, the fixed plate group 2 and the movable plate group 3 are both opened, the die jacket 12 includes a first die jacket 121 and a second die jacket 122, and the first die jacket 121 and the second die jacket 122 are movably connected.

[0032] Specifically, both the fixed plate group 2 and the movable plate group 3 are set to be open, and the opening directions are the same. By rotating the die jacket 12, the first die jacket 121 can be installed or removed at the open position. The movable drive unit 4 is a hydraulic cylinder, and the movable drive unit 4 can drive the movable plate group 3 to move along the axial direction of the tube to be crimped. When it is necessary to crimp the intermediate joint of the tube, firstly rotate the die jacket 12 to move the first die jacket 121 to the open position of the movable plate group 3, open the first die jacket 121, place the tube joint to be crimped in the die core 11, install the first die jacket 121 on the second die jacket 122, rotate the die jacket 12 to make the docking interface of the first die jacket 121 and the second die jacket 122 away from the open position, at this time the movable drive unit 4 is actuated to drive the die jacket 12 to move to the side of the die core 11 and complete the crimping action. After the crimping of the intermediate joint is completed, the movable drive unit 4 drives the die jacket 12 to repeat the crimping operation. The die head inner core 11 is opened, and the die head outer sleeve 12 is rotated to rotate the first die head outer sleeve 121 to the opening position of the movable plate group 3. The first die head outer sleeve 121 is opened to take out the pipe fittings. The fixed plate group and the movable plate group adopt an opening design. This design allows the pipe fittings to be easily taken out from the opening after the buckling is completed, and no laborious pulling along the axial direction is required, which reduces the work intensity and improves the work efficiency. The die head outer sleeve 12 can be rotatably installed on the movable plate group 3, and the second die head outer sleeve 122 is rotated to a suitable angle relative to the movable plate reinforcement cover 31 to strengthen the locking force of the movable plate group 3 when the die head outer sleeve 12 is buckled. It can avoid the concentration of force at the joint position of the first die head outer sleeve 121 and the second die head outer sleeve 122. The movable connection between the first die head outer sleeve 121 and the second die head outer sleeve 122 facilitates the installation and removal of pipe fittings.

[0033] like Figure 1 As shown, a fixed plate reinforcement cover 21 with a rectangular matching structure is provided at the opening position of the fixed plate group 2, and a movable plate reinforcement cover 31 is provided at the opening position of the movable plate group 3. The fixed plate reinforcement cover 21 is movably connected to the fixed plate group 2, and the movable plate reinforcement cover 31 is movably connected to the movable plate group 3.

[0034] Specifically, by providing the fixed plate reinforcement cover 21 and the movable plate reinforcement cover 31 of the rectangular matching structure, the structural strength of the fixed plate group 2 and the movable plate group 3 at the opening position is significantly enhanced. During the buckling process, especially when buckling larger or harder pipes, these reinforcement covers can effectively prevent the plate group from being deformed or damaged due to excessive force, thereby ensuring the stability and durability of the equipment. In this embodiment, the fixed plate reinforcement cover 21 is hinged to the fixed plate group 2, and the movable plate reinforcement cover 31 is hinged to the movable plate group 3, which is convenient for opening or closing and improves work efficiency.

[0035] like Figure 1 As shown, the opening of the fixing plate set 2 is V-shaped.

[0036] Specifically, compared with other shapes, the V-shaped opening can better disperse the force generated during the buckling process, thereby enhancing the structural stability of the fixed plate group 2 and helping to reduce the risk of deformation or damage of the fixed plate group 2 during buckling.

[0037] like Figure 2 , 3 As shown, the die inner core 11 and the die outer shell 12 are both cones.

[0038] Specifically, the cone-shaped die head inner core 11 can distribute the buckling pressure more evenly during the buckling process. During buckling, the die head inner core 11 gradually shrinks and the buckling pressure can gradually increase, thereby ensuring that the pipe joint can receive uniform force in the entire buckling area, improving the buckling quality and consistency, and reducing quality problems caused by uneven buckling.

[0039] like Figure 2 , 3 As shown, the die core 11 is composed of at least two die blocks 111 , and the die blocks 111 are movably mounted on the fixed plate group 2 , and the die blocks 111 are fan-shaped.

[0040] Specifically, the die jacket 12 moves toward the die core 11 and squeezes the die block 111, and the die block 111 moves along the radial direction of the pipe to squeeze the metal joint to complete the crimping. In this embodiment, a plurality of die blocks 111 are provided.

[0041] like Figure 1 , 3 As shown, the crimping machine is further provided with a limiting unit 5 , and the limiting unit 5 includes a sensor 51 provided on the fixing plate group 2 .

[0042] Specifically, the sensor 51 is a contact switch, which can monitor the position of the movable plate group 3, thereby ensuring that the crimping action reaches a predetermined depth or position, can be adapted to the crimping requirements of different pipe diameters, accurately control the crimping quality, and can also prevent the fixed plate group 2 and the movable plate group 3 from being too close or colliding during the crimping process, thereby protecting the equipment from damage.

[0043] like Figure 1 As shown, a support bench vise 6 is provided along the axial direction of the crimping die 1 , the support bench vise 6 is movably mounted on a guide shaft 61 , and a movable extension rod 62 is provided on the support bench vise 6 .

[0044] Specifically, the bracket bench vise 6 is a positioning-free bracket bench vise. By setting the bracket bench vise 6, the pipe to be crimped can be firmly clamped. Some pipes are long and need to be crimped multiple times at different positions. By pushing the movable extension rod 62, the positioning-free bracket bench vise 6 moves a fixed distance along the guide shaft 61, thereby realizing uninterrupted and continuous crimping operation of the pipe, saving multiple positioning time and improving the crimping efficiency of the pipe.

[0045] like Figure 2 , 3 As shown, the crimping machine is further provided with a support base 7 , the fixed plate group 2 is hingedly mounted on the support base 7 , and the mobile drive unit 4 is movably mounted on the support base 7 .

[0046] Specifically, the support base 7 is used to avoid possible shaking or displacement during the crimping process, thereby ensuring the crimping accuracy and safety and facilitating transportation; the fixed plate group 2 is hinged to the support base 7 to ensure that the two are coaxial during the crimping process, thereby avoiding bending forces caused by different axes.

[0047] The present application discloses a crimping machine, which is provided with a die core 11 and a die jacket 12, wherein the die core 11 is mounted on a fixed plate group 2, and the die jacket 12 is rotatably mounted on a movable plate group 3. Both the fixed plate group 2 and the movable plate group 3 are open-set with the same opening direction. By rotating the die jacket 12, the first die jacket 121 can be installed or removed at the opening position, so as to facilitate placing the pipe to be crimped into the die core. The mobile driving unit 4 can drive the die jacket 12 to move toward the position of the die core 11 to complete the crimping. The fixed plate group 2 and the movable plate group 3 adopt an opening design, so that after the crimping is completed, the pipe can be easily taken out from the opening without the need for laborious pulling in the axial direction, thereby reducing the work intensity and improving the work efficiency. The die jacket 12 is rotatably mounted on the movable plate group 3, and the second die jacket 122 is rotated at a suitable angle relative to the movable plate reinforcement cover 31 to strengthen the locking force of the movable plate group 3 on the die jacket 12 when crimping. This can avoid stress concentration at the joint between the first die head housing 121 and the second die head housing 122, making it easier to install and remove pipe fittings.
