Description

Technical Field

[0001] The utility model belongs to the technical field of forging equipment, in particular to a forging die for a transmission shaft end face tooth flange fork. Background Art

[0002] The drive shaft flange fork is an important component of the automobile. It is the main part connecting the transmission and the drive axle, and is also a part with a complex shape that withstands high-speed transmission. It realizes the engine speed conversion and transmission by transmitting power and torque. Hydraulic forging is the main way to produce flange forks. The specific method is to put the forging heated to a high temperature into the molding cavity of the lower mold, and then the hydraulic rod drives the upper mold to press down and complete the mold closing with the lower mold, so as to shape the forging into the style of a flange fork. Since the iron forging needs to be heated to a high temperature during forging, the high-temperature iron forging will be rapidly oxidized with the oxygen in the air, thereby forming a layer of iron oxide slag on the surface of the forging. When the forging is placed in the mold for hydraulic forging, the iron oxide slag will separate from the forging and attach to the inner wall of the molding cavity of the mold. If there is a lot of iron slag accumulated in the molding cavity of the mold, it will affect the appearance flatness of the flange fork, so the iron slag needs to be cleaned.

[0003] When cleaning the mold, since the molding cavity of the upper mold opens downward, the iron slag will automatically fall under gravity and forging contact, and is not easy to accumulate and easy to clean. However, since the opening of the lower mold opens upward, the iron slag is easy to accumulate and adhere to the inner wall of the molding cavity. The existing cleaning method is to manually use a brush to brush off the iron slag on the inner wall. The fallen iron slag accumulates on the bottom surface of the inner wall, and then the iron slag is swept out of the molding cavity along the wall. The cleaning process is cumbersome and time-consuming, and a better cleaning effect can only be achieved after repeated cleaning. Utility Model Content

[0033] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0034] The utility model embodiment provides a transmission shaft end face tooth flange forging die, such as Figure 1-7 As shown, it includes a workbench 1 and a lower mold 6. The lower mold 6 is located at the bottom end of the inner cavity of the workbench 1. A first slide groove 2 with an upper end and side walls being open is provided in the middle of the bottom end of the inner cavity of the workbench 1. A support seat 3 is axially slidably connected in the inner cavity of the first slide groove 2. The upper end of the support seat 3 contacts the lower end of the lower mold 6. One end of the workbench 1 is located below the opening of the side wall of the first slide groove 2 and is fixedly connected with a first support plate 5. A first electric push cylinder 4 is installed and fixed on the upper end of the first support plate 5. The output end of the first electric push cylinder 4 is fixedly connected to the side wall of the support seat 3.

[0035] Iron slag cleaning components are distributed on the lower mold 6, the support base 3 and the workbench 1;

[0036] The iron slag cleaning assembly includes an angle adjustment unit having a first rotating motor 10, a fixing unit having a sliding fixing block 14 and a fixing groove 12, and a cleaning unit having a cleaning device 27;

[0037] The first rotary motor 10 is used to drive the lower mold 6 to rotate, and the molding cavity opening of the lower mold 6 rotated 180 degrees faces downward;

[0038] The fixed groove 12 and the sliding fixed block 14 in the docking state are used to limit the lower mold 6;

[0039] The rotating cleaner 27 is used to clean the iron slag remaining on the inner wall of the molding cavity of the lower mold 6.

[0040] In this embodiment, after multiple hydraulic forgings, a large amount of iron slag is accumulated and attached to the inner wall of the molding cavity of the lower mold 6. At this time, the iron slag needs to be cleaned to prevent the iron slag from affecting the appearance quality of the flange fork during forging.

[0041] When cleaning, the staff first pulls the sliding plate 15 upwards, and the sliding plate 15 drives the sliding fixed block 14 to move upwards along the second slide groove 13, and the lower end of the sliding fixed block 14 leaves the fixed groove 12. At this time, the fixation of the lower mold 6 and the support seat 3 is released. As it continues to rise, the first magnetic block 17 on the sliding plate 15 is adsorbed by the second magnetic block 19 above, thereby achieving the fixation of the sliding fixed block 14;

[0042] Afterwards, the first electric push cylinder 4 drives the support seat 3 to slide along the first slide groove 2 to the other end, so that the lower end of the lower mold 6 is no longer in contact with the support seat 3, providing space for the rotation of the lower mold 6;

[0043] Then, the lower mold 6 is driven to rotate to an angle where the molding cavity opening is vertically downward through the first rotating motor 10, the first rotating shaft 7, the coupling 8 and the second rotating shaft 9. During the rotation process, part of the iron slag directly leaves the lower mold 6 and falls under the action of gravity;

[0044] Subsequently, the second electric push cylinder 21 is started, and the output shaft of the second electric push cylinder 21 is extended, thereby driving the connecting shaft 22, and the collecting basket 23, the second rotating motor 26 and the sweeper 27 on the connecting shaft 22 to rise;

[0045] As it continues to rise, the cleaner 27 enters the molding cavity of the lower mold 6. At this time, the second rotating motor 26 drives the cleaner 27 to rotate, and the rotating cleaner 27 cleans the iron slag attached to the inner wall. The cleaned iron slag falls into the collection basket 23 and is collected, thereby quickly cleaning the lower mold 6.

[0046] When a large amount of iron slag is accumulated in the collecting frame 23 , the iron slag can be swept out from the outlet 24 and transferred.
