In this embodiment, a total of 19 fixed character components 10 are installed in the character stamping detachable module 1 .

[0039] The character fixing assembly includes a spring fixing part 7, a character spring 8 and a character fixing block 9; each spring fixing part 7 is fixedly connected to the fixed plate base 4, and each spring fixing part 7 is connected to the character fixing block 9 through the character spring 8. The character fixing block 9 is provided with a protruding block extending toward the mounting groove near the fixed character part 10, and grooves are provided on both sides of the fixed character part 10. The character spring 8 is in a compressed state and has a movement tendency to drive the character fixing block 9 to press downward.

[0040] The character fixing components may also be bolts and nuts.

[0041] like Figure 4 and Figure 5As shown, the commonly used seal character quick replacement module 2 includes a seal plate support frame 11, a cylinder body 12, a seal plate spring 13, a slider fixing part 14, a support shaft 15 and a character replacement part 16; the seal plate support frame 11 is rotatably installed in the middle of the knife disc cover plate 3, the cylinder body 12 is fixedly installed on the seal plate support frame 11, and a plurality of sliding grooves arranged at equal intervals along the circumference are opened in the seal plate support frame 11, each sliding groove is arranged along the radial direction of the seal plate support frame 11, the cylinder body 12 is provided with a plurality of output rods, and the plurality of output rods are respectively arranged in the corresponding sliding grooves, and each output rod is coaxially fixedly connected with the corresponding support shaft 15, and the support shaft 15 is fixedly connected with the corresponding character replacement part 16.

The oil cylinder body 12 drives the corresponding support shaft 15, so that the character replacement part 16 moves from the waiting position in the seal disk support frame to the seal vacant position of the character stamping detachable module 1, so that the rail hot stamping machine can continue to work normally, and realize the fully automatic and rapid replacement of a single character without interacting with the stamping code disk. The stamp disk spring 13 is used for resetting, and the stamp character to be replaced is reset to the stamp disk. In this embodiment, the commonly used stamp character quick replacement module is provided with 12 commonly used stamp characters that can be replaced.

[0042] The steel mill identification symbol consists of an English capital letter, such as P for Pansteel, A for Ansteel, B for Baosteel, W for Wuhan Steel, etc. During the hot stamping process of the rail, there is a situation where the steelmaking year, converter serial number and other digital identifications remain unchanged, while the steel mill identification symbol changes. Therefore, the replacement character part 16 can be set to the steel mill identification symbol, such as "P", "A", "B".

[0043] The embossed character surface of the fixed character part 10 / replaceable character part 16 is flat or arc-shaped, and the protruding character surface contour is chamfered. By chamfering, the pressure can be more evenly distributed at the edges and corners of the embossed characters to avoid stress concentration. When the embossing speed of the control equipment is synchronized with the rolling speed, the rotating embossing cutter disc maintains a consistent linear speed when in close contact with each section of the rail on the conveyor belt, avoiding stress concentration and facilitating the implementation of fully automated assembly line character embossing.

[0044] like Fig.11 , Fig.12 and Fig.13As shown, the stamping device includes a rail automatic character stamping tool disc and a code disc.

A plurality of replacement character pieces are placed in the rotating character storage table at equal intervals along the circumference. The rotating character storage table is also equipped with a character replacement tool through a mounting frame. The structure of the character replacement tool is as follows: Fig.10 As shown, the character replacement tool changes the connection relationship between the target fixed character part 10 and its character fixing component, so that the target fixed character part 10 falls off from the rail automatic character stamping tool disc to the rotating character storage table, and the rotating code disc selects the replacement character part as the fixed character part 10 and installs it in the rail automatic character stamping tool disc. When the rail automatic character stamping tool disc is moved to the top of the rotating character storage table by the robot arm, the rail automatic character stamping tool disc is parallel to the rotating character storage table. When the character replacement tool is not used for replacement, the character part fixing block 9 is connected to the character spring 8. The bottom of the character part fixing block 9 has two symmetrical 45° inclined surfaces, and there is a boss on the left and right sides respectively. The character spring 8 is fixed on the spring fixing part 7, and the spring fixing part 7 is fixed on the fixed plate base 4. The character spring 8 is in a compressed state as a whole, and there is a force on the character part fixing block 9 in the direction of the spring restoring the unloaded state, so that the boss of the character part fixing block 9 and the side groove of the fixed character part 10 form a tenon fit. The spring character replacement tool moves vertically downward and passes through the circular holes on the blade cover 3 and the fixed plate side baffle 4 in turn, and then acts on the 45° inclined surface at the bottom of the character part fixing block 9, wherein the component force in the same direction as the compression direction of the character spring 8 causes the character part fixing block 9 to move along the compression direction of the character spring 8. The boss of the character part fixing block 9 and the groove of the fixed character part 10 are loosely matched, and the fixed character part 10 falls into the placement position of the corresponding character on the code disk. The code disk is then rotated to correspond the new fixed character part 10 to be replaced to the detachable module of the blade disk. The boss of the character part fixing block 9 and the side groove of the new fixed character part 10 re-form a tenon fit, and then the spring character replacement tool is removed, completing the rapid replacement process of the entire character imprinting detachable module.

[0046] The utility model maintains the integrity of the rail hot stamping cutter disc while ensuring full automation of rail hot stamping. The detachable structure cooperates with the translation device, the swivel arm device and the character replacement device to quickly replace the character module on the rail hot stamping cutter disc. The translation device is driven horizontally on the linear axis by a servo motor to move the stamping head of the equipment horizontally from the normal position to the preset position and back. The swivel arm device moves the stamping head from the waiting position or the change position to the stamping position. The stamping device realizes the character replacement function through two manipulators for changing characters and a rotating character storage table with 88 characters.

[0047] After a group of hot rails of the same model are all stamped, the rail hot stamping cutter disc is rotated from contact with the hot rail to parallel to the ground through the swivel arm device, and then moved to the top of the rotating character storage table in the stamping device through the translation device. Finally, the character module is disassembled and replaced with the assistance of the character changing manipulator. The character stamping detachable module is used to quickly replace the character parts, which improves the efficiency and safety of the rail hot stamping machine.

[0048] Finally, it should be noted that the above embodiments and descriptions are only used to illustrate the technical solution of the utility model and are not intended to limit it.
