Description

Technical Field

[0001] The utility model relates to the technical field of flywheel structures, in particular to a flywheel device of an electric screw press. Background Art

[0002] An electric screw press is a forging and stamping equipment that uses a motor to drive a flywheel and a screw mechanism to convert the rotational energy of the flywheel into the linear motion of a slider, thereby forging or stamping a metal workpiece. In the production process of containers, an electric screw press can be used to forge or stamp container parts such as corner columns, side panels, and door panels. When the flywheel device of an existing electric screw press is in use, the flywheel is generally installed on a corresponding support frame through a shaft rod, and the flywheel is generally an integral type. In this way, when the gear ring on the side of the flywheel is worn, the flywheel needs to be removed as a whole. In addition, since the two ends of the flywheel shaft rod are usually inserted into the corresponding rotating part, in order to maintain the stability of the insertion, there is a certain interference fit between the shaft rod and the rotating part. This makes it more troublesome to remove the shaft rod from the rotating part and reinsert the shaft rod into the rotating part, which is not conducive to the replacement and maintenance of the flywheel as a whole. Utility Model Content

[0003] The purpose of the utility model is to provide a flywheel device for an electric screw press to solve the problems raised in the above background technology.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] Furthermore, the inner side surface of one end of the rectangular rod is screwed and connected with a locking screw in contact with the side surface of the wheel body.

[0007] Furthermore, a multi-faceted ring is fixedly connected to the side surface of the wheel body, and a plurality of straight surfaces in contact with the side surface of the multi-faceted ring are arranged on the side surface of the arc rack.

[0008] Furthermore, the two straight surfaces on the arc rack are fixedly connected with a plug rod which is slidably connected to the inner side of the wheel body, and the side surface of the plug rod is slidably connected to the inner side surface of the multi-faceted ring.

[0009] The cam is connected to the locking plate of the locking plate, and the locking plate is connected to the locking plate by a locking mechanism, wherein the locking plate is connected to a locking mechanism, wherein the locking plate is connected to a locking mechanism, wherein the locking plate is connected to the locking plate by a locking mechanism.

[0010] Furthermore, the back surfaces of the two tapered blocks are each provided with a trapezoidal groove, and the inner side surfaces of the tapered grooves are fixedly connected with a trapezoidal block which is slidably connected with the inner side surfaces of the adjacent trapezoidal grooves.

[0011] Preferably, a multi-faceted groove is formed on the side surface of the fixing cylinder corresponding to the screw-on ring, and a positioning screw in contact with the inner side surface of the multi-faceted groove is screwed and connected to the side surface of the screw-on ring.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The arc rack is slidably connected with two adjacent L-shaped blocks through the connecting groove. Both ends of the arc rack are provided with L-shaped blocks inserted in the connecting groove. The rectangular rod can limit the L-shaped block inside the connecting groove, so that the four arc racks are fixed to the wheel body through the four rectangular rods. When the arc rack is worn and needs to be replaced, the rectangular rod can be pulled out from the wheel body. At this time, the arc rack can be directly removed from the surface of the wheel body without replacing the wheel body, which is conducive to the rapid replacement of the arc rack.

[0014] 2. A conical block in contact with the inner side of the conical groove is fixedly connected through a connecting shaft, and the rotating ring can limit the position of the sliding seat through the connecting ring and the sliding rod. The sliding seat can limit the position of the limit seat so that the conical inner side of the conical groove is in close contact with the conical side of the conical block, thereby positioning and supporting the conical block and the connecting shaft through the limit seat to prevent the conical block from shaking. When the wheel body needs to be replaced or overhauled, the rotating ring can be rotated to move the rotating ring away from the connecting shaft, thereby moving the sliding seat and the limit seat away from the connecting shaft. Since the inner side of the conical groove is conical, the conical block can be easily pulled out of the limit seat. After moving the limit seat to the inside of the fixed cylinder, the connecting shaft and the wheel body can be directly taken out from between the two fixed cylinders, which is convenient for quick disassembly and assembly of the wheel body.

DETAILED DESCRIPTION

[0023] 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.

[0024] See also Figure 1-5 In an embodiment of the utility model, a flywheel device of an electric screw press comprises a mounting frame 1, a connecting shaft 2 is arranged inside the mounting frame 1, a wheel body 21 is fixedly connected to the side of the connecting shaft 2, four arc racks 3 are arranged equidistantly in an annular manner on the side of the wheel body 21, two L-shaped blocks 31 are fixedly connected to both ends of the side of the arc rack 3, four connecting grooves 23 are equidistantly arranged in an annular manner on both sides of the annular side of the wheel body 21 corresponding to the L-shaped blocks 31, the inner side of the connecting groove 23 is slidably connected to the side of two adjacent L-shaped blocks 31, four rectangular rods 4 are equidistantly slidably connected to the side of the wheel body 21 corresponding to the connecting groove 23, the rectangular rod 4 passes between two adjacent connecting grooves 23, and the side of the rectangular rod 4 contacts the side of the four adjacent L-shaped blocks 31, and the inner side of one end of the rectangular rod 4 is screwed and connected to a positioning screw 41 contacting the side of the wheel body 21.

[0025] Specifically, two adjacent connecting grooves 23 form a group, and four groups of connecting grooves 23 are distributed in an annular manner at equal intervals on the wheel body 21. Two L-shaped blocks 31 are provided at both ends of the arc rack 3. The L-shaped blocks 31 of two adjacent arc racks 3 can be inserted into the same connecting groove 23. The two L-shaped blocks 31 in the same connecting groove 23 can surround each other. The rectangular rod 4 can be inserted between the L-shaped blocks 31 in the two connecting grooves 23. The L-shaped block 31 is restricted in the connecting groove 23 by the rectangular rod 4 to prevent the arc rack 3 and the L-shaped block 31 from moving away from the wheel body 21.

In this way, only the arc rack 3 can be replaced, and there is no need to replace the wheel body 21, which is conducive to the quick replacement of the arc rack 3.

[0026] Embodiment 1

[0027] like Figure 5 As shown, in this embodiment, a multi-faceted ring 24 is fixedly connected to the side of the wheel body 21, and a plurality of straight surfaces in contact with the side of the multi-faceted ring 24 are provided on the side of the arc rack 3. The two straight surfaces on the arc rack 3 are fixedly connected to a plug-in rod 32 which is slidably connected to the inner side of the wheel body 21, and the side of the plug-in rod 32 is slidably connected to the inner side of the multi-faceted ring 24.

[0028] During specific implementation, the arc rack 3 can be stably connected to the wheel body 21 by inserting the plug-in rod 32 into the wheel body 21, thereby avoiding sliding between the arc rack 3 and the wheel body 21, and a number of straight surfaces on the arc rack 3 are respectively in contact with a number of side surfaces of the multi-faceted ring 24, thereby preventing the arc rack 3 from rotating relative to the wheel body 21 through the multi-faceted ring 24, which is beneficial to improving the stability of the connection between the arc rack 3 and the wheel body 21.

[0029] like Figure 6-7As shown, in this embodiment, the inner side surfaces of both sides of the mounting frame 1 are fixedly connected with fixed cylinders 5 corresponding to the connecting shaft 2, the inner side surfaces of the fixed cylinder 5 are slidably connected with a sliding seat 51, the inner side surfaces of the sliding seat 51 are rotatably connected with a limiting seat 52, the opposite surfaces of the two limiting seats 52 are provided with tapered grooves 56, and the inner side surfaces of the tapered grooves 56 are slidably connected with the side surfaces of the connecting shaft 2, both ends of the connecting shaft 2 are fixedly connected with tapered blocks 22 that contact the inner side surfaces of the tapered grooves 56, the opposite back surfaces of the two sliding seats 51 are fixedly connected with two sliding rods 54 that are slidably connected with the inner side surfaces of the fixed cylinder 5, the sides away from the sides of the two fixed cylinders 5 are provided with a screw-on ring 6, the inner side surfaces of the screw-on rings 6 are rotatably connected with a connecting ring 62 that is fixedly connected to the ends of the two adjacent sliding rods 54, and the side surfaces of the fixed cylinder 5 are provided with threads that are screwed together with the inner side surfaces of the screw-on rings 6.

[0030] During specific implementation, the inside of the screw-on ring 6 is screwed with the thread on the fixed cylinder 5, so that the screw-on ring 6 is connected to the fixed cylinder 5. The screw-on ring 6 can limit the position of the sliding seat 51 through the connecting ring 62 and the sliding rod 54. The sliding seat 51 can limit the position of the limiting seat 52, so that the conical inner side surface of the conical groove 56 is in close contact with the conical side surface of the conical block 22, so that the limiting seat 52 can position and support the conical block 22 and the connecting shaft 2 through the conical groove 56.

[0035] During specific implementation, the end of the positioning screw 61 can be against a corresponding surface inside the multi-faceted groove 55, so that the multi-faceted groove 55 can limit the rotation of the positioning screw 61 relative to the fixed tube 5, thereby limiting the rotation of the screw-on ring 6 relative to the fixed tube 5, avoiding loosening of the screw-on ring 6, which is beneficial to improving the stability of the screw-on ring 6 and stably limiting the connecting shaft 2 between the two limit seats 52.

[0036] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
