Description

Technical Field

[0001] The utility model relates to the technical field of steel ball forging, in particular to a high-chromium steel ball forging device. Background Technique

[0002] During the production of steel balls, the steel billet is usually clamped by a tool clamp and forged under an air hammer. When an industrial air hammer forges steel balls, the heated steel billet needs to be forged repeatedly for many times. Especially for high-carbon chromium wear-resistant steel balls, due to their high hardness, more hammering times are required during production. Through the forging device, the spherical processing of high-chromium steel balls can be realized, the strength and wear resistance of high-chromium steel balls can be improved, and the needs of the industrial field for high-performance materials can be met;

[0003] In the existing high-chromium steel ball forging device, during the hammering process of the air hammer cover, the forging is easily stuck in the sizing hole of the moving die arranged at the lower end of the air hammer. Therefore, during the forging process, the forging is easily driven to fall off from the fixed die. It is necessary to manually put the forging into the cavity of the fixed die with the help of a long clip. This process not only affects the forging efficiency, but also the forging falls to the ground, causing the steel ball to deform, which will affect the quality and yield rate of the steel ball, and is easy to roll during the process, which is likely to cause harm to the surrounding personnel. At the same time, the forging is also easily stuck in the fixed die, making it inconvenient to take out the steel ball. For this reason, we propose a high-chromium steel ball forging device. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a high-chromium steel ball forging device, which can effectively solve the problems in the background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A high-chromium steel ball forging device, including a machine body, the center position of the top end of the machine body is detachably connected with an air hammer through bolts, and the power output end of the air hammer penetrates through the top end of the machine body and extends to the upper end of the inner cavity of the machine body. The power output end of the air hammer is detachably connected with a moving die. A feeding chute is opened on the inner cavity surface of the machine body. A fixed die is detachably nested and connected at the center position of the inner cavity of the feeding chute and relative to the position of the moving die. A second ejection assembly is arranged at the bottom end of the inner cavity of the fixed die, and a second ejection assembly is arranged on one side of the inner cavity of the moving die relative to the fixed die.

[0006] Preferably, the second ejection assembly includes an assembly hole opened on one side of the inner cavity of the moving die relative to the fixed die. A spring telescopic rod is detachably connected in the inner cavity of the assembly hole, and a second top plate is fixedly connected to the inner side wall of the spring telescopic rod.

[0007] Preferably, the second ejection component includes a nested hole vertically opened at the bottom end of the fixed mold. A first top plate is arranged above the nested hole. The bottom end of the fixed mold is detachably provided with an electric telescopic rod, and the power output end of the electric telescopic rod penetrates through the nested hole and extends into the inner cavity of the fixed mold and is detachably connected to the back of the first top plate.

[0008] Preferably, a tapered discharge port is opened on one side of the material guiding chute, and a discharge frame is detachably connected to the discharge end of the tapered discharge port.

[0009] Preferably, an assembly groove is opened at the bottom end of the surface of the machine body, and a control rod for controlling the air hammer is arranged in the inner cavity of the assembly groove.

[0010] Preferably, a control panel is detachably connected to the surface of the machine body.

[0011] Preferably, the electric telescopic rods are all electrically connected to an external power supply through the control panel.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. By setting the first ejection component and the second ejection component to cooperate with each other, during the forging process, when the moving mold separates from the forging, there is no longer an interaction force between the moving mold and the forging. As a result, the spring telescopic rod in the assembly groove of the inner cavity of the moving mold will push the second top plate outwards, causing the second top plate to push the forging outwards, preventing the forging from being stuck in the moving mold, preventing the moving mold from lifting the forging, avoiding dropping, preventing damage to the steel balls. At the same time, after the forging is forged into a ball, the electric telescopic rod drives the first top plate to move upwards and push the steel ball upwards, so that the steel ball can be quickly ejected from the fixed mold, which can not only improve the forging efficiency but also ensure the quality of the steel ball forging.

[0014] 2. Through the first ejection component, the material guiding chute, the tapered discharge port and the discharge frame, the electric telescopic rod drives the first top plate to move upwards and push the steel ball upwards, so that the steel ball can be quickly ejected from the fixed mold and fall into the material guiding chute, and move down along the material guiding chute, and then roll towards the tapered discharge port, and enter the discharge frame under the guidance of the tapered discharge port. With the help of the discharge frame, the sphere is quickly discharged along the fixed installation track, saving time and effort, and further improving the forging efficiency of the high-chromium steel balls.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Embodiment

[0021] Please refer to Figure 1 - Figure 3 , a high-chromium steel ball forging device shown in the figure, including a machine body 1. The center position at the top of the machine body 1 is detachably connected with an air hammer 2 through bolts, and the power output end of the air hammer 2 penetrates through the top of the machine body 1 and extends to the upper end of the inner cavity of the machine body 1. The power output end of the air hammer 2 is detachably connected with a moving die 3. A material guiding chute 5 is opened on the inner surface of the inner cavity of the machine body 1. A fixed die 4 is detachably nested and connected at the center position of the inner cavity of the material guiding chute 5 and relative to the position of the moving die 3. A second discharging component is arranged at the bottom end of the inner cavity of the fixed die 4, and a second ejecting component is arranged on one side of the inner cavity of the moving die 3 relative to the fixed die 4; both the moving die 3 and the fixed die 4 are connected to the air hammer 2 and the machine respectively through bolts, so that both the moving die 3 and the fixed die 4 are convenient to disassemble and assemble, and thus can be quickly replaced when damaged, ensuring the forging effect of high-chromium steel balls.

[0022] Among them, the second discharging component includes an assembly hole 14 opened on one side of the inner cavity of the moving die 3 relative to the fixed die 4. A spring telescopic rod 15 is detachably connected in the inner cavity of the assembly hole 14, and the inner side wall of the spring telescopic rod 15 is fixedly connected with a second top plate 16; when the moving die 3 is separated from the forging, the moving die 3 and the forging no longer have mutual acting forces, so that the spring telescopic rod 15 in the assembly groove 7 of the inner cavity of the moving die 3 will push the second top plate 16 outwards, making the second top plate 16 push the forging outwards, preventing the forging from being stuck in the moving die 3, preventing the moving die 3 from lifting the forging, avoiding dropping, and preventing the steel balls from being damaged.

[0023] Among them, the second discharging component includes a nested hole 13 vertically opened at the bottom end of the fixed mold 4. Above the nested hole 13, there is a first top plate 11. The bottom end of the fixed mold 4 is detachably provided with an electric telescopic rod 12, and the power output end of the electric telescopic rod 12 penetrates through the nested hole 13 and extends into the inner cavity of the fixed mold 4 to be detachably connected to the back of the first top plate 11. A conical discharge port 9 is opened on one side of the material guiding chute 5, and the discharging end of the conical discharge port 9 is detachably connected with a discharge frame 10. After the steel ball is formed, the electric telescopic rod 12 is controlled to drive the first top plate 11 to move upward and push the steel ball upward, so that the steel ball can be quickly pushed out of the fixed mold 4 and fall into the material guiding chute 5, and move downward along the material guiding chute 5, and then roll towards the conical discharge port, and enter the discharge frame 10 under the guidance of the conical discharge port. With the help of the discharge frame 10, the installation and fixing track of the sphere is quickly discharged, which saves time and effort and effectively improves the forging efficiency of high-chromium steel balls.

The surface of the machine body 1 is detachably connected with a control panel 6, and the electric telescopic rods 12 are all electrically connected to an external power supply through the control panel 6. By arranging the control rod 8 in the assembly groove 7 opened on the body of the machine body 1, the control rod 8 can be prevented from being exposed to the outside, thereby preventing external personnel from easily touching the control rod 8 during forging and preventing accidental touch, and improving the safety during forging.

[0025] It should be noted that the present utility model is a high-chromium steel ball forging device. The steel billet is clamped to the lower mold by a tool clamp, and then the operator presses the control rod 8 with his foot. The air hammer 2 is controlled by the control rod 8 to drive the upper mold to press downward until the steel billet forms a steel ball. After forming, the electric telescopic rod 12 drives the first top plate 11 to move upward and push the steel ball upward, so that the steel ball can be quickly pushed out of the fixed mold 4 and fall into the material guiding chute 5, and move downward along the material guiding chute 5, and then roll towards the conical discharge port, and enter the discharge frame 10 under the guidance of the conical discharge port. With the help of the discharge frame 10, the installation and fixing track of the sphere is quickly discharged, which saves time and effort and effectively improves the forging efficiency of high-chromium steel balls.
