DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1 and Figure 2A quick die-changing system shown is applied to forging press equipment, comprising a trolley moving track 1 and a die-changing trolley 2, the trolley moving track 1 is paved on the ground and extends toward the forging press equipment, the die-changing trolley 2 is installed and runs on the trolley moving track 1, a first fixed die table 3 and a second fixed die table 4 are installed on the side of the trolley moving track 1, the first fixed die table 3 and the second fixed die table 4 are arranged in parallel, the die-changing trolley 2 can respectively form a docking with the first fixed die table 3 and the second fixed die table 4 during operation, the first fixed die table 3 and the second fixed die table 4 have the same structure, a die-laying frame 31 is installed on the first fixed die table 3 and the second fixed die table 4, a die-receiving frame 21 is installed on the die-changing trolley 2, and the mold can be transferred and moved between the die-laying frame 31 and the die-receiving frame 21. In the utility model, the first fixed die table 3 and the second fixed die table 4, One can be used to place a new die, and the other can be used to place a removed old die. During actual operation, the new die is first hoisted onto the first fixed die table 3, and then the old die on the forging press equipment is removed and transferred to the die changing trolley 2 (since the trolley moving track 1 is paved and extends to the forging press equipment, the die changing trolley 2 can directly move to the forging press equipment to pick up the removed die), and the removed die is transferred to the second fixed die table 4 by the die changing trolley 2, and then the die changing trolley 2 is moved to the position of the first fixed die table 3 to pick up the new die, and then the die changing trolley 2 is moved to the forging press equipment again to cooperate with the replacement of the new die. The utility model has a reasonable layout, and the die changing operation is completed through the transfer movement of the die. The application of the utility model can greatly reduce the difficulty of the die changing operation, reduce the working pressure of the workers, and help to improve the efficiency of the die changing operation.

[0022] like Figure 1 As shown, a plurality of rollers 211 are rotatably mounted on the mold frame 21. The plurality of rollers 211 are arranged in a straight line along the length direction of the mold frame 21. The rollers 211 play a role in lifting the mold. Since the rollers 211 are rotatable, workers can push the heavy mold along the length direction of the mold frame 21 with a small amount of force, and the entire moving process is relatively labor-saving.

[0023] like Figure 2 As shown, a lifting push cylinder 23 is installed on the mold changing trolley 2, and the lifting push cylinder 23 is installed vertically upward. The piston rod end of the lifting push cylinder 23 is fixedly connected to the bottom of the mold receiving frame 21. The lifting push cylinder 23 can drive the mold receiving frame 21 to move up and down. Two mold placing seats 22 are installed on the table of the mold changing trolley 2. The two mold placing seats 22 are arranged on both sides of the mold receiving frame 21. The mold receiving frame 21 can receive the mold after being driven to rise. The mold receiving frame 21 can be flush with the table of the mold changing trolley 2 after being lowered. At this time, the mold is no longer in contact with the mold receiving frame 21, but is only placed on the two mold placing seats 22. The mold placing seats 22 play a role in positioning the mold.

[0024] like Figure 1As shown, a plurality of rollers 311 are installed on the mold placing frame 31, and the plurality of rollers 311 are arranged in a straight line along the length direction of the mold placing frame 31. The effect of the rollers 311 is similar to that of the rollers 211, and they also play a lifting role. Similarly, since the rollers 311 are rotatable, workers can easily push the mold to move along the length direction of the mold placing frame 31. There are two mold placing frames 31 installed, and the two mold placing frames 31 are arranged in parallel. The mold can be placed on the two mold placing frames 31. After the mold receiving frame 21 is driven to rise, the mold receiving frame 21 of the mold changing trolley 2 can be flush with the mold placing frame 31 of the fixed mold table. At this time, the mold transfer movement operation between the car and the table can be carried out.

[0025] like Figure 1 As shown, a plurality of positioning components 32 are installed on the table tops of the first fixed mold table 3 and the second fixed mold table 4. The mold needs to be temporarily stored on the fixed mold table. In order to prevent the mold from falling during temporary storage (the mold can be moved on the mold frame 31, and there is a possibility of accidental sliding), the utility model designs a positioning component 32 to position and fix the mold. The positioning component 32 includes a vertical plate 321 and a positioning screw 322. The vertical plate 321 is fixed on the table top, and the positioning screw 322 is threadedly installed on the vertical plate 321. When the mold is not moved and temporarily stored, the positioning screw 322 is twisted toward the mold to fix the mold so that it will not move at will.

[0026] like Figure 1 As shown, a limit frame 33 is installed on the table top of the first fixed mold table 3 and the second fixed mold table 4. The limit frame 33 is installed on the side away from the mold changing trolley 2. The limit frame 33 limits the farthest movement position of the mold to prevent the mold from falling from the outer end of the mold table due to excessive pushing force after being transferred to the fixed mold table.

[0027] like Figure 3 A quick-change die shown in the figure is used in the aforementioned quick-change die system, which includes a die frame 5, in which a plurality of die seats 6 are installed, each die seat 6 includes an upper and a lower die, which is used to forge and form bearing ring blanks. In the case of multiple die seats 6, multiple products can be forged at the same time to improve production efficiency. A plurality of docking protrusions 51 are connected to the outer wall of the die frame 5, and the docking protrusions 51 are arranged toward the forging machine equipment. After the die is pushed onto the forging machine equipment, it is docked with the forging machine equipment through the docking protrusions 51. Two movable guide plates 52 are connected to the bottom of the die frame 5. The die holder 22 on the die-changing trolley 2 is arranged at a 90-degree angle to the die holder 21. A guide groove 221 is provided on the die holder 22, and the two movable guide plates 52 can be inserted into the guide grooves 221 of the two die holders 22 one by one. Figure 1As shown, the die receiving frame 21 is arranged horizontally and can receive and place the die horizontally. The die setting base 22 is arranged vertically and is just facing the forging press equipment. When changing the die, the die setting base 22 plays a role in guiding the movement of the die, so that the die can be smoothly pushed onto the forging press equipment (when changing or removing the die, the die moves along the length direction of the die setting base 22).

[0028] The existence of the movable guide plate 52 at the bottom of the mold frame 5 will affect the lateral movement of the mold. Therefore, when the mold needs to be transferred laterally, the mold receiving frame 21 must be driven up first. At this time, the movable guide plate 52 will gradually disengage from the guide groove 221. When completely disengaged, the movable guide plate 52 no longer interferes with the lateral movement of the mold. At this time, force can be applied to perform lateral transfer movement (when the mold receiving frame 21 rises to the upper limit, the movable guide plate 52 is completely disengaged from the guide groove 221, and the mold receiving frame 21 is flush with the mold placing frame 31).

[0029] like Figure 1 and Figure 3 As shown, a plurality of positioning holes 53 are provided on the outer wall of the mold frame 5, and the positioning holes 53 are arranged corresponding to the positioning components 32. When the mold is temporarily stored, the positioning screw 322 on the positioning component 32 is just inserted into the positioning hole 53 to fix the mold. Before the mold needs to be transferred, the positioning screw 322 must be screwed out first. A push-pull handle 54 is connected to the outer wall of the mold frame 5. The push-pull handle 54 is arranged to facilitate workers to apply force and facilitate workers to transfer the moving mold.

[0030] The utility model adopts push-pull operation when disassembling and replacing the mold, which has the advantages of simple operation and little space restriction. The utility model not only solves the problem of small space of the forging machine and inconvenient mold disassembly and assembly, but also makes the operation of workers very labor-saving.

[0031] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
