Description

Technical Field

[0001] This utility model relates to the field of hot heading machine technology, and in particular to a feeding mechanism for a hot heading machine. Background Technology

[0002] The feeding mechanism of a hot upsetting machine generally consists of two oppositely arranged metal feeding rollers. The rollers have grooves on their surfaces that match the bar stock. The two rotating feeding rollers convey the bar stock by pressing it into the grooves and generating friction. During the feeding process, a large amount of heat is generated between the feeding rollers and the bar stock. This heat causes the feeding rollers to heat up and deform, which in turn causes the bar stock to get stuck in the grooves and affect the feeding of the hot upsetting machine.

[0003] To address the aforementioned problems, this utility model provides improvements. Utility Model Content

[0004] This utility model proposes a feeding mechanism for a hot heading machine, which solves the above-mentioned problems existing in the use of the prior art.

[0005] The technical solution of this utility model is implemented as follows: A feeding mechanism for a hot forging machine includes a frame, a drive feeding wheel, and a driven feeding wheel. A cooling shaft, which is rotatably mounted on the frame and driven by a drive motor mounted on the frame, is fixedly connected to the end of the cooling shaft. The driven feeding wheel is rotatably mounted on the frame and matches the drive feeding wheel. A cooling channel is formed inside the cooling shaft, extending axially through the shaft, so that an outlet and an inlet are formed at both ends of the cooling shaft, respectively. The outlet is located on the side closer to the drive feeding wheel, and the inlet is located on the side farther from the drive feeding wheel. A water inlet pipe communicating with the inlet is provided on the frame.

[0006] Preferably, two cooling shafts are arranged side by side, and each of the two cooling shafts is fixedly connected to a driven gear. The output shaft of the drive motor is fixedly connected to a driving gear that meshes with the two driven gears. There are two driving feed wheels and two driven feed wheels.

[0007] Preferably, the frame is provided with two coaxial swinging upper pull rods, and a transmission swing arm is fixedly connected to the upper pull rod. The two transmission swing arms are respectively rotatably connected to the output shafts of two cylinders provided on the frame, and the two driven feed wheels are respectively rotatably provided at the ends of the two upper pull rods.

[0008] Preferably, a cooling ring groove is formed on the inner wall of the active feed wheel, and a plurality of water outlet holes communicating with the cooling ring groove are opened on the outer end face of the active feed wheel, and a plurality of water inlet holes communicating with the cooling ring groove are opened on the inner wall of the cooling channel.

[0009] Preferably, the active feed wheel includes an active inner wheel ring and an active outer wheel ring. The active inner wheel ring is fixedly connected to the end of the cooling shaft, and the active outer wheel ring is expanded to the outside of the active inner wheel ring. The cooling ring groove and the water outlet hole are respectively provided on the inner wall and the outer end face of the active inner wheel ring.

[0010] Preferably, the driven feed wheel includes a driven inner wheel ring and a driven outer wheel ring, the driven inner wheel ring being rotatably disposed at the end of the upper pull rod, and the driven outer wheel ring being expanded to the outside of the driven inner wheel ring.

[0011] In summary, the beneficial effects of this utility model are as follows: when the active feed wheel and the driven feed wheel cooperate to convey and feed the bar stock, the water inlet pipe connected to the external water supply device delivers cooling water into the cooling channel through the water inlet. The cooling water in the cooling channel flows out of the cooling channel through the water outlet, realizing the continuous flow of cooling water in the cooling channel. This allows the heat generated when the active feed wheel conveys the bar stock to be conducted to the cooling shaft and carried away, thereby achieving the cooling effect on the active feed wheel and preventing the active feed wheel from deforming due to excessive temperature, thus ensuring the stability of the hot upsetting machine during feeding.

[0015] The following will refer to the appendix in the embodiments of this utility model. Figure 1-4The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0016] As shown in the figure, a feeding mechanism for a hot forging machine includes a frame 1 (not fully shown in the figure), an active feeding wheel 2, and a driven feeding wheel 3. A cooling shaft 4 is rotatably mounted on the frame 1 and is connected to a drive motor 5 mounted on the frame 1. The active feeding wheel 2 is fixedly connected to the end of the cooling shaft 4. The driven feeding wheel 3 is rotatably mounted on the frame 1 and matches the active feeding wheel 2. A cooling channel 41 is formed inside the cooling shaft 4, which runs through the cooling shaft 4 axially, so that an outlet 42 and an inlet 43 are formed at both ends of the cooling shaft 4, respectively. The outlet 42 is located on the side closer to the active feeding wheel 2, and the inlet 43 is located on the side away from the active feeding wheel 2. A water inlet pipe 6 connected to the inlet 43 is provided on the frame 1.

[0017] Specifically, the structure of the cooling shaft 4 and the drive motor 5 is as follows: two cooling shafts 4 are arranged side by side, and each of the two cooling shafts 4 is fixedly connected to a driven gear 7. The output shaft of the drive motor 5 is fixedly connected to a driving gear 8 that meshes with the two driven gears 7. There are two driving feed wheels 2 and two driven feed wheels 3.

[0018] Specifically, the driven feed wheel 3 is rotatably mounted on the frame 1: the frame 1 is provided with two coaxial swinging upper pull rods 9, and a transmission swing arm 10 is fixedly connected to the upper pull rod 9. The two transmission swing arms 10 are respectively rotatably connected to the output shafts of two cylinders 11 mounted on the frame 1, and the two driven feed wheels 3 are respectively rotatably mounted at the ends of the two upper pull rods 9.

[0019] In the above structure, during bar feeding, the bar is placed on the active feed wheel 2 and located in the groove of the active feed wheel 2. Two cylinders 11 drive two upper pull rods 9 to swing via two transmission swing arms 10. The two upper pull rods 9 drive two driven feed wheels 3 to swing towards the active feed wheel 2, contacting the bar placed on the active feed wheel 2, thus clamping the bar between the active feed wheel 2 and the driven feed wheels 3. Then, the drive motor 5 drives the active gear 8 to rotate. The active gear 8 meshes with two driven gears 7, causing the two driven gears 7 to rotate synchronously and in the same direction. The two driven gears 7 drive two cooling shafts 4 to rotate synchronously and in the same direction. The two cooling shafts 4 drive the two active feed wheels 2 to rotate synchronously and in the same direction. The rotating active feed wheels 2, in conjunction with the rotation of the driven feed wheels 3, convey the bar forward, achieving feeding. Simultaneously, a water supply device (usually a pump) is connected to the system. The water inlet pipe 6 delivers cooling water into the cooling channel 41 through the water inlet 43. The cooling water in the cooling channel 41 flows out of the cooling channel 41 through the water outlet 42, allowing the cooling water to flow slowly and continuously within the cooling channel 41. The heat generated when the active feed wheel 2 conveys the bar stock is conducted to the cooling shaft 4 and carried away by the continuously flowing cooling water, thus achieving the cooling effect on the active feed wheel 2. This ensures that the temperature of the active feed wheel 2 does not become too high and cause deformation, thereby ensuring the stability of the hot upsetting machine during feeding and conveying. It should be noted that the connection between the water inlet pipe 6 and the water inlet 43 can be achieved by fixing the water inlet pipe 6 on the frame 1 and aligning its opening with the water inlet 43 (since the flow rate of the cooling water is slow, it can meet the requirements of cooling water delivery), or it can be achieved through a rotary joint. After the cooling water flows out from the water outlet 42, a recycling pipeline can be installed to guide it back to the recycling pool for recycling.

[0020] Furthermore, based on the above structure, a cooling ring groove 23 is formed on the inner wall of the active feed wheel 2, and several water outlet holes 24 communicating with the cooling ring groove 23 are opened on the outer end face of the active feed wheel 2. Several water inlet holes 44 communicating with the cooling ring groove 23 are opened on the inner wall of the cooling channel 41. Part of the cooling water flowing in the cooling channel 41 enters the cooling ring groove 23 through the water inlet holes 44, and the cooling water entering the cooling channel is discharged through the water outlet holes 24, so as to realize the continuous flow of cooling water in the cooling channel, thereby enhancing the cooling effect on the active feed wheel 2.

[0021] Furthermore, based on the above structure, the active feed wheel 2 includes an active inner wheel ring 21 and an active outer wheel ring 22. The active inner wheel ring 21 is fixedly connected to the end of the cooling shaft 4, and the active outer wheel ring 22 is tightened around the outside of the active inner wheel ring 21. The cooling ring groove 23 and the water outlet 24 are respectively provided on the inner wall and outer end face of the active inner wheel ring 21. Similarly, the driven feed wheel 3 includes a driven inner wheel ring 31 and a driven outer wheel ring 32. The driven inner wheel ring 31 is rotatably mounted on the end of the upper pull rod 9, and the driven outer wheel ring 32 is tightened around the outside of the driven inner wheel ring 31. When the feed roller 2 and the driven feed roller 3 work together to feed the bar stock, the driving outer wheel ring 22 and the driven outer wheel ring 32 are in close contact with the bar stock. The wear during feeding occurs on the driving outer wheel ring 22 and the driven outer wheel ring 32. Only the driving outer wheel ring 22 and the driven outer wheel ring 32 need to be replaced, instead of replacing the entire driving feed roller 2 and the driven feed roller, thereby reducing production costs. Furthermore, by replacing the driving outer wheel ring 22 and the driven outer wheel ring 32 with different sizes of wheel grooves to adapt to bar stocks with different outer diameters, it is possible to achieve the feeding of bar stocks with different outer diameters at a lower cost.

[0022] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
