Description

Technical Field

[0001] The invention relates to the technical field of draw rod production, in particular to a draw rod forging mechanism for heavy-duty forging equipment. Background Art

[0002] Forging is a combination of forging and stamping. It is a forming method that uses the hammer, anvil, punch or die of a forging machine to apply pressure to the blank to cause plastic deformation, thereby obtaining a part of the desired shape and size. During the tie rod forging process, the tie rod needs to be positioned and transported.

[0003] For example, a heavy-duty forging equipment tie rod forging mechanism disclosed in the Chinese patent with the announcement number CN218310672U belongs to the technical field of tie rod production, and includes a fixed seat, an upper forging roller, a lower forging roller and a driving device; the upper forging roller is arranged on the upper part of the fixed seat through a bracket, and the lower forging roller is arranged on the lower part of the fixed seat through an axis and connected to the driving device; the driving device includes a motor, a driving gear and a driven gear; the motor is arranged on one side of the fixed seat, and the output end of the motor is connected to the driving gear through a connecting shaft; the driven gear is meshed with the driving gear and connected to the lower forging roller; it can solve the feeding problem in the tie rod forging process and improve work efficiency;

[0004] Some problems were found when using the tie rod forging mechanism of the above-mentioned existing heavy-duty forging equipment. First, to adjust the height of the upper forging roller, two screws need to be rotated at the same time. For two screws with a large span, it is difficult for a single person to synchronously rotate and adjust the height of the upper forging roller. Secondly, the upper and lower forging rollers are used to clamp and convey the tie rod. The upper and lower clamping cannot limit the tie rod to the left and right, resulting in the problem that the tie rod will deflect left and right when subjected to force. Summary of the invention

[0005] The object of the present invention is to provide a tie rod forging mechanism for heavy forging equipment to solve the existing problems raised in the above background technology.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a tie rod forging mechanism for heavy-duty forging equipment, comprising two fixed seats, a lower forging roller is rotatably installed between the two fixed seats via an axis: a limiting slide groove is provided in the fixed seat, a U-shaped connecting frame is slidably installed in the limiting slide groove, an upper forging roller is rotatably installed in the U-shaped connecting frame via an axis, a threaded screw is rotatably installed on the upper forging roller, a connecting cross plate is fixedly connected between the two fixed seats, a threaded sleeve block is embedded in the connecting cross plate, the threaded sleeve block is threadedly matched with the threaded screw, a limiting roller shaft is rotatably installed between the two fixed seats and in front of the lower forging roller, and a limiting collar is symmetrically slidably installed on the limiting roller shaft.

[0007] Preferably, a movable frame is fixedly connected below the fixed seat, a power motor is fixedly connected to a side surface of the fixed seat on one side, and an output end of the power motor is fixedly connected to the lower forging roller.

[0008] Preferably, the front and rear surfaces of the U-shaped connecting frame are fixedly connected with limiting sliders, and the limiting sliders are slidably matched with the limiting sliding grooves.

[0009] Preferably, a rotating disk is fixedly connected to the upper end of the threaded screw.

[0010] Preferably, a rotation connection hole is provided in the fixing seat, the limiting roller is rotatably installed in the rotation connection hole through a bearing, a limiting adjustment groove is provided in the limiting roller, and a bidirectional threaded rod is rotatably installed in the limiting adjustment groove.

[0011] Preferably, a limit adjustment block is fixedly connected to the inner wall of the limit collar, the limit adjustment block is slidably matched with the limit adjustment groove, a threaded through hole is provided in the limit adjustment block, and the threaded through hole is threadedly matched with the bidirectional threaded rod.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The U-shaped connecting frame can be driven to move by rotating the threaded screw, and the movement of the U-shaped connecting frame can drive the upper forging roller to move, thereby adjusting the distance between the upper forging roller and the lower forging roller. Compared with the existing device, only the threaded screw needs to be rotated alone, which is convenient for single-person operation.

[0014] 2. By rotating the two-way threaded rod to drive the limit collar to move, the two limit collars are respectively against the two sides of the pull rod, thereby limiting the pull rod, effectively avoiding the problem of left and right deviation of the pull rod during the feeding process. The two-way threaded rod is used to adjust the spacing of the limit collars, so that pull rods of different sizes can be limited. BRIEF DESCRIPTION OF THE DRAWINGS

The limiting roller shaft 3 is at the same height as the lower forging roller 102. The pull rod will be placed on the limiting roller shaft 3, and the symmetrically arranged limiting rings 4 are used to press against both sides of the pull rod to limit the pull rod, effectively avoiding the problem of left and right deviation of the pull rod during the feeding process. The limiting ring 4 is slidably sleeved on the surface of the limiting roller shaft 3. At the later stage, the distance between the two limiting rings 4 is adjusted according to the radius of the pull rod, so that the device can adapt to the feeding of pull rods of different specifications.

[0024] Among them, in order to achieve the purpose of adjusting the height of the upper forging roller 202, the present device is implemented by adopting the following technical scheme: a movable frame 101 is fixedly connected to the bottom of the fixed seat 1, a power motor 103 is fixedly connected to the side of one side of the fixed seat 1, the output end of the power motor 103 is fixedly connected to the lower forging roller 102, and the front and rear surfaces of the U-shaped connecting frame 2 are fixedly connected to a limiting slider 201, the limiting slider 201 is slidably matched with the limiting slide groove 107, and the upper end of the threaded screw 203 is fixedly connected to a rotating disk 204.

Starting the power motor 103 can drive the lower forging roller 102 to rotate, and the rotation of the lower forging roller 102 will drive the pull rod to feed.
