[0002] Spring hot pressing refers to a processing method that pressurizes and deforms metal springs under specific heating conditions. When the spring material is heated, it becomes softer and easier to deform due to the increase in temperature. At this time, when subjected to appropriate pressure, it can be formed into the required shape of the workpiece. Spring hot pressing is conducive to adjusting the shape, size, hardness and other parameters of the spring, which can optimize the performance of the spring and reduce the occurrence of adverse deformation. The spring hot pressing method can be applied to the spring processing of various metal materials, mainly in the automotive, mechanical, electrical and other fields.

[0003] In the existing spring hot pressing process, the spring is first put into the furnace for hot air heating, and then taken out and placed on a hot press after heating for a certain period of time. The hot press is used to pressurize the spring to deform it and put it together. The existing hot press has only a simple pressurizing structure, and the spring lacks positioning when placed. During the pressurizing process, the spring is easily twisted, which affects the hot pressing quality of the spring. Therefore, an automatic electric tailgate hot press for an electric tailgate system is proposed. Summary of the invention

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0022] Reference Figure 1-5 As shown, a fully automatic electric tailgate hot press for an electric tailgate system comprises a processing table 1 and a positioning mechanism 2, a plurality of legs 11 are connected to the bottom of the processing table 1, two symmetrically distributed fixed plates 12 are connected to the processing table 1, the tops of the two fixed plates 12 are commonly connected to a top plate 13, a hydraulic cylinder 14 is installed on the top plate 13, the movable end of the hydraulic cylinder 14 passes through the top plate 13 and is connected to a connecting plate 15, a disc-shaped base 16 is installed on the processing table 1, a disc-shaped pressing block 17 is connected to the connecting plate 15, and the positioning mechanism 2 is arranged on the processing table 1 to position and adjust the hot pressed spring.

[0023] In this embodiment, the positioning mechanism includes four positioning rods 22 and a turntable 23. The processing table 1 and the base 16 are jointly provided with four movable grooves 21 in a circular array. The four positioning rods 22 are slidably connected to the movable grooves 21. The groove walls on both sides of each movable groove 21 are provided with slide grooves 211. The lower end of each of the positioning rods 22 is connected to a pair of sliders 221. The pair of sliders 221 on each of the positioning rods 22 is slidably connected to a pair of slide grooves 211. The turntable 23 is rotatably connected to the bottom of the processing table 1. The turntable 23 is coaxially arranged with the base 16. The bottom end of each of the positioning rods 22 is connected to a limiting rod 222. Four arc-shaped limiting grooves 231 are provided on the turntable 23 in a circular array. The four limiting grooves 231 are slidably connected to the four limiting rods 222 respectively.

[0024] In this embodiment, a slide rail 24 is installed at the bottom of the processing table 1, and a moving seat 241 is slidably connected to the slide rail 24. Two mounting plates 25 are connected to the moving seat 241. Two sliding rods 251 are connected between the two mounting plates 25. A moving block 252 is slidably connected to the two sliding rods 251. A spur rack 26 is connected to the moving block 252. A gear ring 27 is coaxially connected to the outer ring surface of the turntable 23. The gear ring 27 is meshed with the spur rack 26. A threaded rod 28 is rotatably connected between the two mounting plates 25. The threaded rod 28 is threadedly connected to the moving block 252, and one end of the threaded rod 28 is coaxially connected to a rocker 281.

[0025] In this embodiment, the end of the connecting plate 15 away from the pressing block 17 is connected to a lifting plate 29, and a guide groove 291 is provided on the lifting plate 29. The movable seat 241 is connected to a guide rod 292, and the guide rod 292 is slidably connected to the guide groove 291. The guide groove 291 consists of a straight groove 2911 and an inclined groove 2912, and the inclined groove 2912 is located at the bottom of the lifting plate 29.

[0026] In this embodiment, the base 16 and the pressing block 17 are located on the same axis. A cross-shaped through groove 171 is opened in the center of the pressing block 17. The groove width of the through groove 171 is greater than the groove width of the movable groove 21, which facilitates the positioning rod 22 to pass through the through groove 171 of the pressing block 17.

[0027] In this embodiment, the base 16, the pressure block 17 and the positioning rod 22 are all made of nickel-chromium alloy. The base 16, the pressure block 17 and the positioning rod 22 are in direct contact with the high-temperature spring for a long time. The base 16, the pressure block 17 and the positioning rod 22 made of nickel-chromium alloy have strong wear resistance and high strength, which can improve the service life of the entire hot press device.

[0028] The working process and principle of the present invention are as follows:

[0029] When in use, the manipulator inserts the heated spring into the four positioning rods 22 and places them on the base 16, then turns on the hydraulic cylinder 14 to push the connecting plate 15 down. Before the pressure block 17 descends and contacts the spring, the lifting plate 29 will descend together, and the inclined groove 2912 on the lifting plate 29 will push the guide rod 292 to slide outward, thereby driving the moving seat 241 to slide outward of the processing table 1, pulling the spur rack 26 to move, and the meshing transmission between the spur rack 26 and the gear ring 27 drives the turntable 23 to rotate, and the limit groove 231 on the turntable 23 is used to push the four positioning rods 22. The rod 22 slides outward along the moving groove 21 at the same time, and the four positioning rods 22 are equivalent to stretching the inside of the spring, adjusting the position of the spring on the base 16, so that the spring, the base 16 and the pressure block 17 are located on the same axis. When the pressure block 17 is pressed down, the four positioning rods 22 support the spring from four directions, which can effectively avoid the spring from twisting during hot pressing and improve the quality of hot pressing. After the hot pressing is completed, the pressure block 17 is lifted, and as the lifting plate 29 rises, the four positioning rods 22 will retract and no longer support the spring, which is convenient for the robot to clamp and replace.

[0030] When hot pressing springs of different diameters, the rocker 281 can be rotated first to drive the threaded rod 28 to rotate, and the thread can be used to control the moving block 252 to slide right. Through the meshing transmission of the spur rack 26 and the gear ring 27, the turntable 23 is rotated to push the four positioning rods 22 to slide toward the center, and then the spring is placed on the base 16, and the hydraulic cylinder 14 is turned on to push down. At this time, the lifting plate 29 descends to control the outward sliding distance of the positioning rod 22 to be limited, and the positioning rod 22 does not contact the spring. At this time, the reversible rocker 281 can drive the moving block 252 to slide left. During the movement of the moving block 252, the four positioning rods 22 will also slide outward together until the four positioning rods 22 are in contact with the spring, thereby completing the position adjustment of the positioning rod 22. When hot pressing springs of the same size and specification are subsequently performed, the four positioning rods 22 can all slide into place to position and adjust the spring and support it internally, so that each hot press machine can be suitable for hot pressing springs of different specifications, thereby improving the scope of use of the device.

[0031] It is known from common technical knowledge that the present invention can be implemented by other embodiments that do not deviate from its spirit or essential features. Therefore, the above disclosed embodiments are only illustrative in all respects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
