Description

Technical Field

[0001] This utility model relates to the field of gear manufacturing, and in particular to a precision forging machine for precision gear blanks. Background Technology

[0002] Gears are important processed transmission components in mechanical transmission. The processing precision and cost of gears are relatively high compared to general parts. Hot die forging is still a widely used blank forging process for automotive gear parts. However, this method of processing gear blanks will result in excessive machining allowance and defects in hardness. Wedge cross rolling technology is increasingly favored by industry professionals because it is suitable for the production of more complex stepped shaft blanks, and has high processing precision and small machining allowance.

[0003] Chinese patent CN209680798U discloses a high-precision circular gear blank forging machine, including a base. Rollers are provided on the lower edge of the base. Two opposing vertical plates are located in the middle of the upper surface of the base. Two parallel rotating shafts are located between the two vertical plates. A working roller is mounted on the upper shaft, and a support roller is mounted on the lower shaft. Both the working roller and the support roller are fixed to the upper and lower shafts respectively by keys. A coupling is located on the right side of the right vertical plate, and a motor is located on the right side of the coupling. This invention uses existing wedge cross-rolling technology instead of traditional hot die forging technology to process gear blanks, effectively reducing the machining allowance of the gear blanks and significantly improving gear production efficiency.

[0004] However, the above-mentioned patent still has certain shortcomings in use. When forging gears, different gears need to be adjusted because of their different sizes. At the same time, when cooling the gears, residue may fall off, causing water pollution and preventing water recycling, resulting in a large waste of water resources. To address these issues, we propose a precision forging machine for precision gear blanks. Utility Model Content

[0005] The purpose of this invention is to provide a precision forging machine for precision gear blanks to solve the problems mentioned in the background art.

[0008] In a further embodiment, each set of support components includes a support leg, and the bottom surface of each support leg is connected to a base.

[0009] In a further embodiment, the forging assembly includes a second motor, two second bearings, and two third bearings. The second motor is located on the outer surface of one of the support plates. The output end of the second motor is connected to a second rotating column. A rotating roller is connected to the outer surface of the second rotating column. The inner rings of the two second bearings are connected to the outer surface of the second rotating column.

An auxiliary roller is connected to the outer surface of the rotating rod. Both third bearings are located on the side of the two adjusting plates that are close to each other.

[0010] In a further embodiment, the cooling assembly includes a water pump, the output end of which is connected to a water pipe, the top end of which passes through a water tank, a support plate, and an adjusting plate in sequence and is connected to a delivery pipe, the outer surface of which is connected to multiple spray heads.

[0011] In a further embodiment, the water tank has two sets of arc-shaped grooves on its outer surface. Each set of arc-shaped grooves has a sliding rod slidably connected to its inner wall.

[0012] In a further embodiment, two slag discharge ports are provided on the outer surface of the water tank.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This device uses an electric push rod inside the groove to drive the adjustment plate, allowing for adjustment according to different gear models, increasing ease of use. Furthermore, the filter screen inside the water tank effectively filters the water used to cool the gears, preventing contamination of the water inside the tank. The rotation of the first motor drives the first rotating column, which in turn rotates the filter screen, cleaning impurities from its outer surface. This allows the water to be recycled, avoiding water waste. Attached Figure Description

[0024] Two support plates 7 are connected to the upper surface of the base plate 1. A forging assembly 3 is connected to one side of the two support plates 7 that are close to each other. The forging assembly 3 includes a second motor 301, two second bearings 303, and two third bearings 305. The second motor 301 is located on the outer surface of one of the support plates 7. A second rotating column 302 is connected to the output end of the second motor 301. A rotating roller 304 is connected to the outer surface of the second rotating column 302.

Thus, the rotating roller 304 forges the gear with the cooperation of the third bearings 305, the rotating rod 306 and the auxiliary roller 307.

[0025] Two grooves 8 are formed on the upper surface of each of the two support plates 7. An electric push rod 9 is connected inside each set of grooves 8. An adjustment plate 10 is connected to the output end of each set of electric push rods 9. A water tank 18 is connected to the upper surface of the base plate 1. Two sets of first bearings 22 are embedded in the inner wall of the water tank 18. A first rotating column 21 is connected to the inner ring of each set of first bearings 22. A filter screen 23 is connected to the outer surface of each of the two first rotating columns 21. A pulley 24 is connected to the outer surface of each of the two first rotating columns 21. A drive belt 25 is fitted on the outer surface of the two pulleys 24. A first motor 20 is connected to the outer surface of the water tank 18.

The electric push rod 9 inside the groove 8 can drive the adjusting plate 10 to be adjusted, so that the operator can adjust the adjusting plate 10 according to different types of gears. The first motor 20 rotates and drives the first rotating column 21, so that the first rotating column 21 drives the filter screen 23 to rotate in the cooperation of the arc-shaped sliding grooves 5 and the sliding rods 6, so that the impurities on the outer surface of the filter screen 23 can be dislodged and discharged through the slag discharge ports 19.

[0026] The working principle of this utility model is as follows:

[0027] In use, the electric push rod 9 is activated, causing the adjusting plate 10 to be raised so that it can be adjusted according to different gears. When it is necessary to clean the filter screen 23, the first motor 20 is activated, causing one of the first rotating columns 21 to rotate using the first bearing 22. Because the two pulleys 24 are meshed, the rotating first rotating column 21 drives the other first rotating column 21 to rotate using the drive belt 25 and pulley 24. This causes the first rotating column 21 to adjust the filter screen 23 in the cooperation of the arc-shaped sliding groove 5 and the sliding rod 6, so that the residue on the outer surface of the filter screen 23 falls off to the slag discharge port 19 for discharge.
