Description

Technical Field

[0001] This invention relates to the field of precision tube technology, and in particular to hot rotary forging production equipment and process for electric welding precision tubes. Background Technology

[0002] Precision tubes are high-precision, high-brightness seamless steel tubes produced by cold drawing or cold rolling processes. Their inner and outer diameters can be accurate to within 0.2mm. While ensuring bending and torsional strength, they are also lightweight, so they are widely used in the manufacture of precision mechanical parts and engineering structures. When hot forging precision tubes, electric welding precision tube hot forging production equipment is required.

[0003] Traditional electric welding precision tube hot rotary forging production equipment mostly uses a single fixing method to fix the precision tube, which has poor fixing effect and is prone to positional displacement when the precision tube is docked with the mold, resulting in docking failure. This directly affects the normal hot rotary forging process of the precision tube and increases the scrap rate. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as poor fixing effect and easy positional displacement of precision tubes when docking with molds, and to propose a hot rotary forging production equipment and process for electric welding precision tubes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

A hot forging die is rotatably mounted on one side of the support. An electric slide rail is symmetrically embedded on the right side of the top of the workbench along the front-back direction. A movable frame that works with the electric slide rail is slidably mounted on the right side of the top of the workbench. A rotating plate is rotatably mounted on one side of the movable frame. A placement slot is opened on the left side of the rotating plate. A precision tube body that works with the hot forging die is placed in the placement slot. A bracket is fixedly connected to the side of the hot forging die and the rotating plate that is away from each other. A first motor is fixedly connected to the side of the support and the movable frame that is away from each other through an extension frame, and the output shaft of the first motor is fixedly connected to the bracket. An auxiliary component that works with the precision tube body is provided on the movable frame.

[0007] Preferably, the auxiliary component includes pressing frames rotatably mounted on the top and bottom left side of the rotating plate, with one end of the pressing frames close to each other abutting the precision tube body. A second motor is fixedly connected to the bottom of the left front side of the rotating plate via a mounting base. Two sets of support plates are fixedly connected sequentially along the vertical direction on the top left side of the rotating plate, and fixed shafts are rotatably mounted on the support plates. First gears meshing with each other are fixedly connected to the fixed shafts. A first pulley connected by belt drive is fixedly connected to the output shaft of the second motor and the lower set of fixed shafts. A first drive frame is fixedly connected to the output shaft of the second motor and the upper set of fixed shafts. A first fixing groove is provided on the pressing frame to cooperate with the first drive frame.

[0008] Preferably, the auxiliary component further includes a fixing frame symmetrically fixedly connected to the front and back sides of the left side of the rotating plate along the front-back direction. A sliding frame is slidably arranged on the left side of the fixing frame, which is close to each other. A placement chamber is opened in the sliding frame, and a spring is fixedly connected in the placement chamber. A push frame is fixedly connected to one end of the spring that is close to each other. The push frame is attached to the precision tube body on one side that is close to each other. Multiple sets of reinforcing plates are fixedly connected in sequence along the left-right direction on the side of the fixing frame that is far from each other. A horizontal shaft is rotatably mounted on the side of the left and right sets of reinforcing plates that are close to each other. A second [unclear - possibly a component or element] is fixedly connected to the left end of the horizontal shaft. The drive frame has a second fixed groove on the sliding frame that cooperates with the second drive frame. A docking shaft is rotatably mounted on the right side of the front set of fixed frames, and the back of the docking shaft is fixedly connected to a lower set of fixed shafts. Meshing bevel gears are fixedly connected to both the docking shaft and the front set of horizontal shafts. The right end of the horizontal shaft passes through the rotating plate and extends to the right. An auxiliary shaft is fixedly connected to the right side of the rotating plate, and meshing second gears are fixedly connected to both the auxiliary shaft and one of the horizontal shafts. A second pulley connected by belt drive is fixedly connected to the other set of horizontal shafts and the auxiliary shaft.

[0009] Preferably, a sliding plate is fixedly connected to the left side of the sliding frame, and the left side of the sliding plate is slidably mounted on the fixed frame.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] This hot forging production equipment for precision welded tubes utilizes auxiliary components and a second motor as the drive source. With the assistance of a first pulley and a first gear, it drives two sets of first drive frames to rotate synchronously in opposite directions. This, in conjunction with a first fixed groove, allows control of the swing angle of the pressing frame, enabling rapid pressing and positioning of the top and bottom of the precision tube body. Simultaneously, the rotation of the first gear drives the docking shaft to rotate synchronously. With the assistance of a bevel gear, a second gear, and a second pulley, this drives two sets of second drive frames to rotate synchronously in opposite directions. With the assistance of the second fixed groove, the front and rear positions of the sliding frame and the pushing frame can be changed synchronously, allowing for simultaneous pressing and positioning of the front and back of the precision tube body. The spring design provides the pushing frame with a certain amount of movement space and enhances the pressing effect on the precision tube body through its elasticity. The four-way positioning method allows for rapid fixing of the precision tube body, ensuring it remains centered for quick docking with the hot forging die without deviation. This improves the overall anti-deviation effect of the equipment and enhances processing accuracy. Attached Figure Description

A rotating plate 6 is rotatably mounted on one side of the movable frame 4. A placement groove 9 is opened on the left side of the rotating plate 6. A precision tube body 10, which cooperates with the hot forging die 3, is placed in the placement groove 9.

The output shaft of the first motor 8 is fixedly connected to the bracket 7. Rotary bearings are embedded on the sides of the support 2 and the movable frame 4 that are close to each other. The inner rings of the two sets of rotary bearings are fixedly connected to the hot forging die 3 and the rotating plate 6, respectively. The design of the rotary bearings facilitates the unobstructed rotation of the hot forging die 3 and the rotating plate 6 without detaching from the support 2 and the movable frame 4. The movable frame 4 is equipped with auxiliary components that cooperate with the precision tube body 10. The auxiliary components include pressing frames 11 rotatably mounted on the top and bottom left sides of the rotating plate 6. The ends of the pressing frames 11 that are close to each other are attached to the precision tube body 10. A second motor 13 is fixedly connected to the bottom of the left front side of the rotating plate 6 via a mounting base. The top left side of the rotating plate 6 is sequentially connected along the vertical direction... Two sets of support plates are fixedly connected, and fixed shafts 14 are rotatably mounted on the support plates. First gears 15 meshing with each other are fixedly connected to the fixed shafts 14. First pulleys 17 connected by belt drive are fixedly connected to the output shaft of the second motor 13 and the lower set of fixed shafts 14. First drive frames 16 are fixedly connected to the output shaft of the second motor 13 and the upper set of fixed shafts 14. The pressing frame 11 has a first fixing groove 12 that cooperates with the first drive frame 16. The auxiliary component also includes fixed frames 18 that are symmetrically fixedly connected to the front and back sides of the left side of the rotating plate 6 in the front-back direction. A sliding frame 19 is slidably arranged on the left side of the fixed frames 18, close to each other. A sliding plate is fixedly connected to the left side of the sliding frame 19, and the left side of the sliding plate slides... The sliding frame 19 is mounted on the fixed frame 18. By setting a sliding plate, the sliding frame 19 can be limited to slide, preventing it from detaching from the fixed frame 18 and improving the stability of the sliding frame 19 during movement. The sliding frame 19 has a placement chamber, and a spring 27 is fixedly connected in the placement chamber. The ends of the springs 27 that are close to each other are fixedly connected to a push frame 28. The sides of the push frames 28 that are close to each other are attached to the precision tube body 10. On the side of the fixed frame 18 that is far from each other, multiple sets of reinforcing plates are fixedly connected in the left and right directions. A horizontal shaft 22 is rotatably mounted on the side of the two sets of reinforcing plates that are close to each other. The left end of the horizontal shaft 22 is fixedly connected to a second drive frame 24. The sliding frame 19 has a second fixing groove 20 that cooperates with the second drive frame 24.A docking shaft 21 is rotatably mounted on the right side of a set of fixed brackets 18 on the front side, and the back of the docking shaft 21 is fixedly connected to a set of fixed shafts 14 below. Meshing bevel gears 23 are fixedly connected to both the docking shaft 21 and a set of horizontal shafts 22 on the front side.

An auxiliary shaft is fixedly connected to the right side of the rotating plate 6, and meshing second gears 25 are fixedly connected to both the auxiliary shaft and one set of horizontal shafts 22. A second pulley 26, connected by a belt drive, is fixedly connected to the other set of horizontal shafts 22 and the auxiliary shaft. By setting... The auxiliary components employ a four-way positioning method, enabling rapid fixation of the precision tube body 10 and ensuring it remains centered. This facilitates quick docking with the hot forging die 3 without deviation, improving the overall anti-deviation effect of the equipment and enhancing machining accuracy. The identical diameters of the two sets of first gears 15 and the two sets of second gears 25 ensure consistent swing angles between the two sets of first drive frames 16 and the two sets of second drive frames 24, further enhancing the positioning effect of the precision tube body 10. A controller is located on the front of the support 2.

[0027] In this invention, the user first places the precision tube body 10 to be processed into the placement groove 9. At this time, the left end of the precision tube body 10 is in a high-temperature and easily moldable state. Then, the user turns on the second motor 13 through the controller. At this time, the second motor 13, with the assistance of the first pulley 17, can drive one set of fixed shafts 14 to rotate. Under the meshing of the first gear 15, it drives the other set of fixed shafts 14 to rotate synchronously in the opposite direction, thereby driving the two sets of first drive frames 16 to rotate synchronously in the opposite direction. At this time, with the cooperation of the first fixed groove 12, the rotating first drive frame 16 drives the two sets of pressing frames 11 to swing synchronously in the opposite direction until they contact the precision tube body 10, thereby pressing the top and bottom of the precision tube body 10 synchronously. When one set of fixed shafts 14 rotates, it drives the docking shaft 21 to rotate synchronously. With the assistance of the bevel gear 23, it can drive one set of horizontal shafts 22 to rotate. At this time, with the assistance of the second gear 25 and the second pulley 26, it can drive the two sets of horizontal shafts 22 to rotate synchronously in the opposite direction. This drives two sets of second drive frames 24 to rotate synchronously in opposite directions, and with the cooperation of the second fixed groove 20, drives two sets of sliding frames 19 to move synchronously in opposite directions, thereby driving two sets of push frames 28 to move and synchronously press and position the front and back of the precision tube body 10. When the push frame 28 moves, the spring 27 will deform, which on the one hand provides the push frame 28 with a certain amount of movement space, and on the other hand, the elastic force can improve the pressing effect on the precision tube body 10. At this time, the four-way positioning method can quickly fix the precision tube body 10 and keep the precision tube body 10 in the center position, which is convenient for quick docking with the hot forging mold 3 and will not cause deviation. Then, the user turns on the first motor 8 and the electric slide rail 5 through the controller. At this time, the first motor 8 drives the hot forging mold 3 and the rotating plate 6 to rotate, thereby driving the precision tube body 10 to rotate, and the electric slide rail 5 controls the left and right position of the precision tube body 10, so that the precision tube body 10 can quickly dock with the hot forging mold 3, thereby performing hot rotary forging.

[0028] The present invention also provides a hot rotary forging production process for electric welded precision tubes, wherein the hot rotary forging production equipment for electric welded precision tubes is used for hot rotary forging production of electric welded precision tubes.

Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention. 。
