DETAILED DESCRIPTION

[0021] The drawings are only used for illustrative description and cannot be understood as limiting the patent; in order to better illustrate the embodiment, some components in the drawings are omitted, enlarged or reduced, and do not represent the size of the actual product.

[0022] It is understandable for those skilled in the art that some known structures and their descriptions in the drawings can be omitted. The technical scheme of the utility model is further described below in combination with the drawings and embodiments.

[0023] As shown in the drawings Figs. 1-3 A multi-station high-stability forging device, which comprises a rack 1 and forging cylinders 11 fixed on both sides of the rack 1, the movable end of each forging cylinder 11 is connected with a mounting plate 12 in sliding connection with the rack 1, a plurality of mounting grooves 121 are formed in the mounting plate 12, and a plurality of upper forging assemblies 2 are detachably arranged in the mounting grooves 121.

[0024] The forging cylinder 11 is connected with a first flow valve, a second flow valve and an exhaust valve, the valve flow coefficient of the first flow valve is greater than that of the second flow valve. When the forging cylinder 11 is in communication with the first flow valve, it is automatically disconnected with the second flow valve, and vice versa. When the first flow valve is in communication with the forging cylinder 11, the forging cylinder 11 operates at a faster speed to perform the forging work; when the second flow valve is in communication with the forging cylinder 11, the forging cylinder 11 moves at a slower speed.

[0025] The upper forging assembly 2 comprises a forging head 21, a limiting piece 22 fixed on the forging head 21 and two wedge-shaped limiting blocks 23 in sliding connection with the limiting piece 22, the wedge-shaped limiting block 23 comprises a locking portion 231 capable of being clamped with the mounting groove 121; a locking spring 24 is arranged between the two wedge-shaped limiting blocks 23, and the locking spring 24 always makes the two wedge-shaped limiting blocks 23 have a mutual moving trend away from each other.

[0026] The unlocking plate 13 is slidably arranged on the rack, and a wedge-shaped unlocking block 131 is fixedly arranged on one side of the unlocking plate 13 close to the mounting plate 12. The wedge-shaped unlocking block coincides with the projection of the wedge-shaped limiting block 23 on the horizontal plane. When the wedge-shaped unlocking block abuts against the wedge-shaped limiting block 23, the wedge-shaped unlocking block makes the locking part of the wedge-shaped limiting block 23 have a movement trend of moving away from the mounting groove.

[0027] The rack 1 is a frame for supporting and fixing various components of the equipment. The forging cylinders 11 are fixed on both sides of the rack 1 to provide forging power. The mounting plate 12 is connected with the movable end of the forging cylinder 11 and can slide on the rack 1 to drive the die to forge. The mounting plate 12 is provided with a plurality of mounting grooves 121, and a plurality of upper forging assemblies 2 can be simultaneously mounted on the mounting plate 12 to realize multi-station simultaneous forging and improve production efficiency.

[0028] The wedge-shaped limiting blocks 23 in the upper forging assembly 2 always have a tendency to move away from each other by the action of the locking spring 24, thereby stably locking the die in the mounting groove 121. The wedge-shaped unlocking block 131 on the unlocking plate 13 cooperates with the wedge-shaped limiting block 23 to quickly unlock the plurality of upper forging assemblies 2, facilitate the replacement of the die, and shorten the downtime.

[0029] In some embodiments, the rack 1 is provided with a placing groove 14 for placing forging materials, and is also provided with an alignment groove 16 corresponding to the limiting part 22. By arranging the placing groove 14 on the rack 1, the operation efficiency is improved.

[0030] In some embodiments, the mounting plate 12 is provided with a positioning hole 122 on the side close to the rack 1, and the upper forging assembly 2 is provided with a positioning protrusion 25 corresponding to the positioning hole 122. The positioning hole 122 is a hole pre-processed on the mounting plate 12 and used for positioning and connecting with the positioning protrusion 25. The positioning protrusion 25 is a protrusion on the upper forging assembly 2 corresponding to the positioning hole 122, which is used for inserting into the positioning hole 122 to realize accurate positioning of the mounting plate 12 and the upper forging assembly 2. Through this positioning structure, the position of the mounting plate 12 during the forging process can be ensured to be accurate, thereby ensuring the quality and precision of the forgings and the stability of the machining process.

[0031] In some embodiments, the rack 1 is rotatably provided with a screw rod and fixedly provided with a light shaft 151, the unlocking plate 13 is threadedly connected with the screw rod, the light shaft 151 is slidably connected with the unlocking plate 13, and the rack 1 is further provided with a driving motor 15 for rotating the screw rod. Through the mechanism, when the driving motor 15 is started, the screw rod starts to rotate, and since the unlocking plate 13 is threadedly connected with the screw rod, the unlocking plate 13 will move along the axial direction with the rotation of the screw rod. When unlocking is needed, the driving motor 15 moves the unlocking plate 13 towards the mounting plate 12, and when normal work is needed, the driving motor 15 moves the unlocking plate 13 away from the mounting plate 12, so as to avoid interference between the unlocking plate 13 and the mounting plate 12.

[0032] The working principle of the utility model is as follows:

[0033] Firstly, the operator places the upper forging and beating assembly 2 on the lower end face of the rack 1, and makes the lower end of the limiting piece 22 of the upper forging and beating assembly 2 abut against the inner bottom wall of the alignment groove 16. At this time, the forging cylinder 11 is communicated with the second flow valve, the forging cylinder 11 drives the mounting plate 12 to move to the lowest point of stroke at a slow speed. In the moving process, due to the shape of the wedge-shaped limiting block 23, the pressure generated after abutting against the mounting groove 121 will make the two wedge-shaped limiting blocks 23 approach each other, so that the two wedge-shaped limiting blocks 23 are clamped into the mounting groove 121. Then, the two wedge-shaped limiting blocks 23 are away from each other under the elastic force of the locking spring 24, so that the locking part 231 of the wedge-shaped limiting block 23 abuts against the upper end face of the mounting groove 121, and the fixing of the upper forging and beating assembly 2 is completed.

[0034] Subsequently, the workpiece is placed in the placing groove 14, the two side forging cylinders 11 are communicated with the first flow valve, and the forging cylinder 11 beats the material at a fast speed.

[0035] When the mold needs to be replaced, the forging cylinder 11 is communicated with the second flow valve, and the mounting plate is driven to move to the lowest point of stroke at a slow speed. Then, the driving motor 15 drives the screw rod to rotate, so that the unlocking plate 13 moves towards the mounting plate 12, so that the wedge-shaped unlocking block 131 abuts against and presses downward the corresponding wedge-shaped limiting block 23, forcing the two wedge-shaped limiting blocks 23 of the upper forging and beating assembly 2 to approach each other, and then the locking part 231 of the wedge-shaped limiting block 23 is away from the upper end face of the mounting groove 121. Finally, the unlocking plate 13 and the mounting plate are synchronously lifted, and the upper forging and beating assembly 2 is separated from the mounting groove 121.

[0036] Obviously, the above embodiments of the present application are merely examples for clearly illustrating the present application, and are not intended to limit the implementation modes of the present application. For those skilled in the art, other different forms of changes or variations can be made on the basis of the above description. Here, it is not necessary and also impossible to exhaust all the implementation modes. Any modification, equivalent replacement and improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application claims.
