Description

Technical Field

[0001] This utility model relates to the technical field of ring forging production equipment, specifically a top circle device for polygonal ring forgings. Background Technology

[0002] During the ring rolling process, due to various reasons, ring forgings often deform into polygonal shapes. Therefore, it is necessary to perform top rounding on the polygonal ring forgings. Previously, when performing top rounding on the ring forgings, since there was no component to abut against it on the other side of the top rounding part, it was easy to cause excessive inward deformation of the top rounding.

[0003] Document CN 210907475 U discloses a device for rounding a polygonal ring forging, comprising: a bracket with two spacer rods arranged side-by-side at the front, a stop post at the rear, and a hydraulic cylinder in the middle. A push rod is mounted on the bottom of the cylinder body and rests against the stop post. The convex deformation section of the polygonal ring forging rests on the bracket between the two spacer rods and the hydraulic cylinder. The device also includes an outer pad, which supports the polygonal ring forging when it rests on the bracket, allowing it to be placed horizontally. However, this structure, when rounding the ring forging, is prone to over-rounding due to the lack of a support object on the opposite side of the rounding component, leading to further deformation.

[0004] Therefore, a new technical solution is needed to solve the above-mentioned technical problems. Summary of the Invention

[0005] To address the aforementioned problems, this utility model discloses a device for rounding polygonal ring forgings. By rotating the ring forging on a limiting pulley on a worktable and then rounding the ring forging with a pushing pad, the device effectively prevents the ring forging from deforming again and improves the rounding efficiency.

[0006] The technical solution of this utility model is: a top circle device for polygonal ring forging, including a drive structure, a push pad, a limiting pulley and an abutment block located on the worktable. The drive structure includes a hydraulic cylinder and a telescopic rod. The push pad is located at the output end of the telescopic rod. The abutment block is located between the two limiting pulleys. The abutment block is fixedly connected to the fixed seat on the worktable by bolts. The bottom of the abutment block is connected to the worktable by a slide rail.

[0007] By adopting the above technical solution, the ring forging is simultaneously abutted against the limiting pulley. Then, according to the position of the ring forging, the abutting block is slid to the corresponding position, and the arc-shaped section of the abutting block abuts against the ring forging. Then, the ring forging is fixed by bolts passing through the screw holes of the arc-shaped section and the worktable. The hydraulic cylinder is started, and the pushing pad block cooperates with the abutting block to perform top rounding treatment on the ring forging.

[0008] Preferably, the bottom of the abutment block is connected by a slider and a slide rail, the slide rail is fixed on the worktable, the movement direction of the slide rail and the telescopic rod is in the same straight line, and the abutment block is located on the center line between the limiting pulleys.

[0009] By adopting the above technical solution, the abutment block slides on the slide rail via a slider. When it slides to a suitable position, the arc-shaped section of the abutment block abuts against the inner wall of the ring forging, thereby abutting the ring forging in the top circle direction.

[0010] Preferably, the abutment block is a rectangle with one end curved, and bolt holes are provided in the curved section. When the abutment block is located at the end of the slide rail near the telescopic rod, the curved section is located on the outside of the slide rail.

[0011] By adopting the above technical solution, when the abutment block moves to the appropriate position, the abutment block is fixed by bolts to prevent displacement of the abutment block, and the ring forging is abutted in the top circle direction to prevent deformation of the ring forging.

[0012] Preferably, the worktable below the arc segment is provided with screw holes for inserting bolt holes within the arc segment, and the screw holes are arranged in a straight line between the slide rail and the telescopic rod.

[0013] By adopting the above technical solution, the jacking pad is fixed with bolts to prevent it from moving.

[0014] Preferably, the limiting pulleys are located on both sides of the telescopic rod in the working direction, and the pulley surface is adapted to the inner surface of the ring forging.

[0015] By adopting the above technical solution, when it is necessary to round the ring forging at different positions, the ring forging needs to be rotated to round the ring at different positions. The limiting pulley can facilitate the displacement and rotation of the ring forging.

[0016] Preferably, the push pad is pushed onto the outer surface of the ring forging, and the push pad and the abutment block are located on both sides of the ring forging, and the worktable through which the ring forging rotates is a plane.

[0017] By adopting the above technical solution, the cooperation between the push pad and the abutment block can increase the support force of the ring forging in the top circle direction.

[0018] Preferably, the hydraulic cylinder is fixed to the workbench by a base plate, and a through hole is provided on the base plate in the direction of the output end of the hydraulic cylinder, through which the telescopic rod passes and is located at the output end of the hydraulic cylinder.

[0019] By adopting the above technical solution, the telescopic rod is driven by a hydraulic cylinder, thereby causing the push pad at the end of the telescopic rod to round the ring forging.

[0020] The advantages of this utility model are as follows: 1. By setting an abutment block inside the ring forging, when the pushing pad block pushes the ring forging to round out, the abutment block just abuts against the inner side of the ring forging, which can effectively prevent the ring forging from deforming inward when it is being pushed to round out.

[0021] 2. This utility model displaces the limiting pulley of the positioning ring forging, which facilitates the rotation of the ring forging when it moves, making it easier for the top pushing pad to perform top rounding treatment on it, thereby increasing the top rounding efficiency of the ring forging.

[0022] 3. This utility model effectively prevents the ring forging from deforming again and improves the rounding efficiency by rotating the ring forging on the limiting pulley on the worktable and then rounding the ring forging by the pushing pad. Attached Figure Description

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0029] like Figure 1-4As shown, the polygonal ring forging top-rounding device includes a drive structure, a push pad 4, a limiting pulley 5, and an abutment block 6 located on the worktable 1. The drive structure includes a hydraulic cylinder 2 and a telescopic rod 201. The push pad 4 is located at the output end of the telescopic rod 201, and the abutment block 6 is located between the two limiting pulleys 5. The abutment block 6 is fixedly connected to the fixed seat 301 on the worktable 1 by bolts. The bottom of the abutment block 6 is connected to the worktable 1 through a slide rail 7. The ring forging 10 is simultaneously abutted against the limiting pulleys 5. Then, according to the position of the ring forging 10, the abutment block 6 is slid to the corresponding position, and the arc-shaped section 601 of the abutment block 6 abuts against the ring forging 10. Then, it is fixed by bolts passing through the screw holes of the arc-shaped section 601 and the worktable 1. The hydraulic cylinder 2 is activated, and the push pad 4 cooperates with the abutment block 6 to perform top-rounding treatment on the ring forging 10.

[0030] The bottom of the abutment block 6 is connected to the slide rail 7 via the slider 8. The slide rail 7 is fixed on the worktable 1. The movement direction of the slide rail 7 and the telescopic rod 201 is on the same straight line. The abutment block 6 is located on the center line between the limiting pulleys 5. The abutment block 6 slides on the slide rail 7 via the slider 8. When it slides to the appropriate position, the arc-shaped section 601 of the abutment block 6 abuts against the inner wall of the ring forging 10, thereby abutting the ring forging 10 in the top circle direction.

[0031] The abutment block 6 is a rectangle with one end curved, and the curved section 601 is provided with bolt holes 602. When the abutment block 6 is located at the end of the slide rail 7 near the telescopic rod 201, the curved section 601 is located outside the slide rail 7. When the abutment block 6 moves to the appropriate position, the abutment block 6 is fixed by bolts to prevent the abutment block 6 from shifting and to abut the ring forging 10 in the top circle direction to prevent the ring forging 10 from deforming.

[0032] The workbench 1 below the arc section 604 is provided with screw holes 9 for the bolt holes 602 inside the arc section 601 to be inserted. The screw holes 9 are arranged in a straight line between the slide rail 7 and the telescopic rod 301. The push pads 4 are fixed by bolts to prevent the push pads 4 from moving.

[0033] The limiting pulleys 5 are located on both sides of the telescopic rod 201 in the working direction. The pulley surface is adapted to the inner side of the ring forging 10. When it is necessary to round the ring forging 10 at different positions, the ring forging 10 needs to be rotated to round the ring forging at different positions. The limiting pulleys 5 can facilitate the displacement and rotation of the ring forging 10.

[0034] The push pad 4 pushes the ring forging 10 onto its outer surface. The push pad 4 and the abutment block 6 are located on both sides of the ring forging 10. According to the actual situation, the arc of the abutment block 6 is slightly larger than the arc of the push pad 4. The worktable 1 through which the ring forging 10 rotates is a plane. The push pad 4 and the abutment block 6 cooperate with each other to increase the support force of the ring forging 10 in the top circle direction.

[0035] The hydraulic cylinder 2 is fixed on the workbench 1 by the base plate 3. The base plate 3 in the output direction of the hydraulic cylinder 2 is provided with a through hole 301. The telescopic rod 201 passes through the through hole 301 and is located at the output end of the hydraulic cylinder 2. The hydraulic cylinder 2 drives the telescopic rod 201, so that the push pad 4 at the end of the telescopic rod 201 pushes the ring forging 10 to be rounded.

[0036] The ring forging 10 that needs to be rounded is placed outside the limiting pulley of the worktable, and then the abutment block 6 is pushed to slide on the slide rail 7. When the abutment block 6 slides to the appropriate position, the bolt passes through the abutment block 6 and the worktable 1 for fixing, and the hydraulic cylinder 2 is driven. The push pad 4 at the end of the telescopic rod 201 rounds the ring forging 10.
