[0002] A hot spinning press is a mechanical device used for metal processing, and it is particularly suitable for materials that need to be heated before spinning. Its working principle is to heat the metal blank and then perform plastic deformation on it during the spinning process to produce various shaped metal parts. In the actual production process, during high-frequency operation of the spinning press, inevitable wear will occur on the surface of the pressure wheel die, and the increase of metal adhesion will affect the processing quality and efficiency of the die. At this time, it is necessary to replace the spinning die.

[0003] Currently, the replacement of spinning dies is mostly carried out by relying on manual labor assisted by a forklift. That is, first place the die on the forklift mast, and then the driver controls the forklift to send the die into the spinning press. The comprehensive problems brought by this are: due to the lack of a dedicated die changing device for the spinning press, the die needs to be accurately docked when being placed inside the equipment. Sending it in by forklift is not only inconvenient to move, there is a certain risk of blind insertion and misoperation, and it is difficult to adjust the accuracy of the die feeding in a short time. At least two people are required to cooperate for positioning. The overall operation is time-consuming and laborious, the die changing time is long, and the process efficiency is low.

In addition, in actual production, three-dimensional spatial dimensions including length, width, and depth should be included.

[0021] In order to make the purpose, technical solutions, and advantages of the present utility model clearer, the following will further describe the embodiments of the present utility model in detail in conjunction with the accompanying drawings.

[0022] Figures 1 - 3Shown is a schematic diagram of the entire structure of a rapid die-changing device for a high-pressure hot spinning machine of the present utility model. Please refer to Figures 1 - 3 , a rapid die-changing device for a high-pressure hot spinning machine in this embodiment includes a base 100 that can be moved and rotated. A sliding seat 200 is horizontally slidably installed on the upper part of the base 100, and a reciprocating driving component 300 for driving the sliding seat 200 to move left and right. An overhanging frame 400 is arranged above the sliding seat 200. The overhanging frame 400 is an adjustable front-back telescopic structure. The upper end of the sliding seat 200 also has a lifting driving component 500 for installing and driving the overhanging frame 400 to move up and down. The telescopic front end of the overhanging frame 400 has a mounting plate 410, and a pneumatic fixture 600 is installed at the front end of the mounting plate 410. Among them, the rapid die-changing device for the high-pressure hot spinning machine has at least two control ends, namely a total controller arranged on the upper part of the base 100, and a remote controller that is moved and controlled by the staff and cooperates with the total controller. A plurality of moving wheels 120 are arranged at the bottom of the base 100, and a power supply unit, that is, a storage battery, of the die-changing device is arranged inside the base 100. It can be understood that the driving mode of the moving wheels 120 here can adopt conventional technologies such as manual pushing, motor driving, etc. In addition, a handle, a steering wheel, etc. can also be equipped at the upper end of the base 100, just to make the die-changing device more convenient to rotate and move, which can be determined according to the actual situation.

[0023] The upper part of the base 100 has a chute 110 that matches the sliding seat 200; the reciprocating drive assembly 300 includes a lead screw 310 rotatably mounted at both ends inside the chute 110 and threadedly connected to the sliding seat 200 through a ball nut, and a servo motor 320 disposed on the base 100 with its output end connected to one end of the lead screw 310. During use, the servo motor 320 drives the lead screw 310 to rotate forward or backward, and drives the sliding seat 200 to move left and right under the cooperation of the nut and the chute 110, thereby driving the cantilever frame 400, the pneumatic fixture 600 and the mold to be inserted more accurately and corresponding to the internal installation station of the spinning machine, without the need to operate the forklift to adjust back and forth repeatedly, saving time and being highly efficient. The lifting drive assembly 500 includes guide columns 510 vertically fixed on both sides of the upper end of the sliding seat 200 and slidably connected to the cantilever frame 400, a top plate 520 fixedly connected to the top of the guide columns 510, and a hydraulic rod 530 vertically installed at the upper end of the sliding seat 200 with its output end connected to the bottom of the cantilever frame 400. During use, the hydraulic rod 530 drives the cantilever frame 400 and the mold at its front end to move up and down under the cooperation of the guide columns 510, so as to adjust the vertical height of the mold, and at the same time it is also convenient for the staff to dock and tighten the installation of the mold and the internal tail top station of the spinning machine. On both sides inside the cantilever frame 400, there are guide sleeves 430 extending to the front end of the cantilever frame 400. On both sides of the back of the mounting plate 410, there are guide rods 420 fixedly installed and slidably telescoping inside the guide sleeves 430. In the middle of the inside of the cantilever frame 400, there is also an electric push rod 440 with its output end connected to the mounting plate 410. During use, the electric push rod 440 pushes the mounting plate 410 to move back and forth, and under the cooperation of the guide sleeves 430 and the guide rods 420, the mounting plate 410 and the pneumatic fixture 600 can move back and forth stably to adjust, so as to realize the adjustment of the front and rear positions of the mold installation, which is simple and efficient.

[0024] On both sides of the working end of the pneumatic fixture 600, there are also L-shaped clamping blocks 610 that are oppositely matched. Since the hot spinning mold is a disc-shaped structure, but the sizes of molds of different specifications are different, therefore, the L-shaped clamping blocks 610 that can be adjusted in spacing and are in an L shape can support and positionally clamp molds of different sizes, and the operation is more stable and safe.

[0025] In summary, for a rapid die-changing device of a high-pressure hot spinning machine according to this embodiment, during use, first place a new die on the pneumatic fixture 600 with a crane and clamp it firmly. Move the device and the front end of the cantilever frame 400 to the working area of the spinning machine through the movable base 100. Subsequently, under the control of the remote controller, cooperate with the slide 200, the reciprocating drive assembly 300, the lifting drive assembly 500 and the telescopic cantilever frame 400 to adjust the pneumatic fixture 600 and the die in the left-right, front-back and up-down directions until the die corresponds to the internal tail-end working station of the equipment. Just operate in the reverse direction during disassembly. In summary, this rapid die-changing device of the spinning machine can achieve flexible and efficient die-changing operations. Only one person is required to complete the replacement operation, effectively reducing the risk of blind insertion and misoperation caused by traditional forklift operations. It has the characteristics of time-saving, labor-saving and high operation efficiency.
