TECHNICAL FIELD

[0001] The present application relates to the technical field of metal composite processing, in particular to an explosion composite butt joint device for thick copper pipe and stainless steel rod. BACKGROUND

[0002] Metal composite processing technology is an important development direction in the current material manufacturing field, especially in the power, metallurgy, chemical industry and other industries, often need to composite different performance of metal, in order to give priority to electrical conductivity, corrosion resistance and structural strength. Copper has excellent electrical conductivity and thermal conductivity, while stainless steel has high mechanical strength and corrosion resistance, and the two can be prepared into composite components with electrical conductivity and corrosion resistance after butt joint by explosion composite process, so it has wide application value in electrical equipment, ocean engineering and corrosion resistant structure manufacturing.

[0003] In the existing explosion composite process of thick copper pipe and stainless steel rod, the coaxiality of the two is usually maintained by manual or simple positioning ring and clamp. However, due to the difference in outer diameter of stainless steel rod in the process of processing and manufacturing, the conventional fixed clamp is difficult to adapt to steel rods of different diameters, and it is often necessary to replace the positioning sleeve or adjust repeatedly, which is complicated in operation process and difficult to ensure the positioning accuracy. In addition, the existing positioning mechanism adopts rigid contact, which is easy to cause the center deviation of steel rod when the stress is uneven, thereby affecting the uniformity and bonding quality of the subsequent explosion composite interface.

[0004] Therefore, the existing technology generally has the following shortcomings: lack of positioning mechanism that can automatically adapt to steel rods of different outer diameters within a certain range, resulting in poor applicability of the device; the structure of positioning block or clamp is single, and it is difficult to maintain stable coaxiality and repeat accuracy during adjustment; the reset relies on manual adjustment, which is low in efficiency and large in error, and it is difficult to meet the high precision butt joint requirements of thick copper pipe and steel rod explosion composite. In summary, there is an urgent need for a butt joint device that can realize automatic adjustment, be suitable for steel rods of different specifications, and ensure high precision coaxial positioning, in order to overcome the shortcomings of the existing technology.

It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0026] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0027] like Figs. 1-3 As shown in the figure, an explosive composite docking device for thick copper tubes and stainless steel rods provided in this embodiment of the invention includes a copper tube positioning ring 7, a support ring 11 connected inside the copper tube positioning ring 7, and a plurality of rotating parts 15 installed at one end of the support ring 11. A copper tube positioning area 12 is formed between the copper tube positioning ring 7 and the support ring 11, and the width of the copper tube positioning area 12 is adapted to the wall thickness of the thick copper tube to be processed. The rotating parts 15 are hinges or unidirectional rotating connection structures of the shaft type.

[0028] The outer side of the rotating part 15 is rotatably connected with the adjustable steel rod positioning block 13, the adjustable steel rod positioning block 13 and the inner side of the supporting ring 11 are jointly provided with the elastic element 14, and the elastic element 14 is a spring or a torsion spring.

[0029] The end, away from the rotating part 15, of the supporting ring 11 is connected with the supporting top plate 10, and the supporting top plate 10 and the supporting ring 11 are jointly provided with a plurality of groups of the precision driving assembly 8, and the precision driving assembly 8 is used for driving the adjustable steel rod positioning block 13 to rotate through the rotating part 15.

[0030] The precision driving assembly 8 comprises the ball nut 83, and the ball nut 83 is slidably connected in the inside of the supporting ring 11; the surface of the supporting top plate 10 is provided with the servo motor 81, and the output end of the servo motor 81 is provided with the ball screw 82, the ball screw 82 is meshedly connected in the inside of the ball nut 83, and the thickness of the ball nut 83 is same as the width between the top of the adjustable steel rod positioning block 13 in the initial state and the supporting ring 11; the surface of the supporting top plate 10 is provided with the controller 9, and the controller 9 is electrically connected with the servo motor 81.

[0031] In one embodiment of the present application, the use process of the thick copper pipe and stainless steel rod explosion composite butt joint device is as follows:

[0032] When the thick copper pipe and the stainless steel rod need to be coaxially positioned, first, the thick copper pipe and the stainless steel rod are placed on the horizontal base plate, so that the axes of the two are approximately coincident. Since the inner diameter and the wall thickness of the thick copper pipe to be processed have small tolerances and relatively stable sizes under the same process condition, and the outer diameter of the stainless steel rod has a slight change, the device mainly adjusts the positioning difficulty caused by the change of the outer diameter of the steel rod.

[0033] In operation, the copper pipe positioning ring 7 is moved above the base plate, so that the copper pipe positioning ring 7 is coaxially arranged with the thick copper pipe and the stainless steel rod, and the thick copper pipe is embedded in the copper pipe positioning area 12. Then, the controller 9 is started to drive the precision driving assembly 8, the servo motor 81 is driven to rotate the ball screw 82, so that the ball nut 83 slides axially along the inner guide slot 84 of the supporting ring 11. When the ball nut 83 moves downward, the upper end of the adjustable steel rod positioning block 13 is contacted, and the positioning block 13 is pushed to rotate unidirectionally around the rotating part 15.

[0034] The adjusting steel rod positioning block 13 is V-shaped structure, the inner included angle is greater than 90°, and a plurality of adjusting steel rod positioning blocks 13 are evenly arranged around the supporting ring 11.When the servo motor 81 drives the ball nut 83 to move downward, a plurality of positioning blocks 13 are simultaneously inclined and rotated inward under the action of the ball nut 83, so that the inner side surfaces of the positioning blocks 13 gradually approach and enclose a positioning ring matched with the outer diameter of the stainless steel rod, thereby realizing self-adaptive holding and coaxial positioning of the stainless steel rod.When the servo motor reverses rotation, the ball nut 83 retreats, and the adjusting steel rod positioning block 13 restores to the initial position under the resetting action of the elastic element 14 (torsional spring or compression spring), so as to replace or adjust the steel rod of different specifications.

[0035] Through the above structural design and automatic driving control, the device can realize rapid, precise and synchronous adjustment and positioning of different outer diameter steel rods without manual measurement and repeated adjustment. A plurality of V-shaped positioning blocks 13 can form a high-consistency holding structure under electric driving, so that the axes of the thick copper pipe and the stainless steel rod can be kept coaxial within a very small error range, thereby providing a stable geometric precision basis for subsequent explosion composite process.

[0036] The technical effects of the embodiment of the present application are as follows:

[0037] 1. Automatic and precise alignment: the inclination angle of the positioning block 13 can be controlled and adjusted synchronously by the servo motor driving and the ball screw transmission system, so as to automatically adapt to stainless steel rods of different diameters.

[0038] 2. High coaxiality and repeat accuracy: the V-shaped positioning structure and the multi-point distributed clamping design enable the copper pipe and the steel rod to be uniformly held under multi-point support, thereby significantly improving the coaxiality and repeat positioning accuracy.

[0039] 3. Stable structure and rapid response: the rotation shaft type one-way rotating part 15 provides a stable rotation fulcrum, and the resetting property of the elastic element 14 enables the device to have rapid resetting capability and shorten the adjustment time.

[0040] 4. Strong applicability and high reliability: the device is suitable for use in the positioning operation before explosion composite of different specifications of steel rods and thick copper pipes, and can be widely applied to the copper-steel dissimilar metal composite manufacturing field, and has good industrial application prospect.

[0041] In the embodiment, the outer surface of the adjusting steel rod positioning block 13 is provided in an arc shape. The arc shape can form continuous contact with the inner wall of the supporting ring 11 when the positioning block 13 rotates around the rotating part 15, so that the movement track of the positioning block is more stable, and the jamming or wear caused by plane contact is avoided.

[0042] In addition, the arc-shaped outer surface can effectively disperse the contact stress when the positioning block is stressed, improve the adhesion and guiding accuracy between the positioning block and the support ring, keep the consistent rotating radius of the plurality of positioning blocks 13 during the inclined movement, and ensure the coaxiality and the circumferential uniformity of the steel bar during positioning.

[0043] Through the structural design, the mechanical friction resistance is reduced, and the wear resistance and service life of the device during repeated adjustment are improved.

[0044] In the embodiment, the inside of the support ring 11 is provided with a guide sliding groove 84, the surface of the ball nut 83 is provided with a guide sliding block 85, and the ball nut 83 is slidably connected to the inside of the support ring 11 through the cooperation of the guide sliding block 85 and the guide sliding groove 84.

[0045] The cooperation structure of the guide sliding groove 84 and the guide sliding block 85 is used to limit the movement direction of the ball nut 83, prevent it from deflecting or shaking during transmission, thereby ensuring the smooth sliding of the ball nut 83 along the axial direction of the support ring 11, and improving the transmission accuracy and structural stability.

[0046] In the embodiment, the outside of the copper pipe positioning ring 7 is connected with a plurality of lifting sleeve rods 5, the inside of the lifting sleeve rod 5 is slidably connected with a sliding rod 3, one end of the sliding rod 3 is connected with a moving base 1, and the surface of the moving base 1 is provided with a self-locking universal wheel 2. The surface of the moving base 1 is provided with an electric telescopic rod 6, one end of the electric telescopic rod 6 is connected with a connecting block 4, and the outside of the connecting block 4 is connected with the outside of the lifting sleeve rod 5.

[0047] The cooperation structure of the lifting sleeve rod 5 and the sliding rod 3 is used to adjust the overall height of the copper pipe positioning ring 7; the electric telescopic rod 6 is used to drive the connecting block 4 to drive the lifting sleeve rod 5 to lift, so as to conveniently adjust the working height and the positioning position of the device according to different working conditions. The self-locking universal wheel 2 is used to make the device flexible during movement and positioning, and stable after locking, so as to facilitate accurate positioning and fixing of the device.

[0048] The above only describes the preferred embodiments of the present application, and is not used to limit the present application, any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
