Description

Technical Field

[0001] This utility model relates to the field of particle steel processing technology, and in particular to a particle steel hot pressing forming device. Background Technology

[0002] Particle steel hot pressing is a near-net-shape forming technology that densifies metal powder (particle steel) into high-density, high-strength materials under high temperature and high pressure. Its core principle is: in a vacuum or protective atmosphere, high temperature and high pressure are applied to metal particles, and the plastic deformation and diffusion bonding mechanism of the particles are used to eliminate pores and form metallurgical bonds, ultimately obtaining a solid-state formed part with a density close to the theoretical density.

[0003] Common particle steel hot pressing forming devices use hydraulic cylinders to press high-temperature metal particles in a trough into metal blocks. This process involves pressing and unloading the material step by step, which takes a long time to press a single piece of particle steel. After pressing, another component is needed to eject it, which is not only time-consuming but also resource-intensive. Therefore, a particle steel hot pressing forming device is proposed to solve the above problems. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model proposes a particle steel hot pressing forming device. By setting up a driving mechanism and a rotating mechanism, it improves production efficiency, reduces the need for downtime cleaning, and increases the continuous operation time and reliability of the equipment.

[0005] This utility model provides a particle steel hot pressing forming device, including a worktable, a frame, a hydraulic cylinder, and a guide hopper. The frame is connected to the top of the worktable, the hydraulic cylinder is mounted on the frame with its telescopic rod pointing vertically downwards, and a pressing block is connected to the bottom of the hydraulic cylinder. The guide hopper is connected to the left side of the frame, a turntable, multiple top plates, and a protrusion. The turntable has multiple pressing grooves, and the multiple top plates are slidably disposed within the multiple pressing grooves. The bottom of each of the multiple top plates is connected to a pulley. The bottom of the turntable has an annular groove that communicates with the multiple pressing grooves. The protrusion is connected to the top of the worktable. The discharge end of the guide hopper is inclined and rotatably provided with a guide pipe. A driving mechanism for driving the guide pipe to rotate is provided on the front side of the guide hopper, and a rotating mechanism for driving the turntable to rotate is provided at the bottom of the worktable.

[0006] Preferably, the protrusion is arc-shaped, with lower sides and higher middle.

[0007] Preferably, the pulley is slidably connected to the top of the worktable and the outer surface of the protrusion.

[0008] Preferably, the driving mechanism includes a fixed frame, a motor, a worm gear, and a worm wheel. The fixed frame is inclinedly connected to the front side of the guide hopper and has the same inclination angle as the guide tube. The motor is located on the front side of the fixed frame. One end of the worm gear is coaxially connected to the output shaft of the motor, and the other end is rotatably connected to the rear sidewall of the fixed frame. The worm wheel is coaxially fixedly sleeved on the guide tube and meshes with the worm gear.

[0009] Preferably, the rotating mechanism includes a rotating cylinder and a rotating shaft. A support frame is connected to the bottom end of the worktable. The rotating cylinder is disposed on the bottom wall of the support frame. One end of the rotating shaft is coaxially and fixedly connected to the output shaft of the rotating cylinder, and the other end is connected to the bottom end of the turntable.

[0010] Preferably, a scraper is connected to the front side of the platform, and its bottom end is close to the top of the turntable.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] By using a rotating mechanism to drive the turntable to rotate, a pressing groove is filled into the inside of the guide pipe as it passes below. The material is then pressed by the hydraulic cylinder below. As the rotation continues, when the pulley rolls on the protrusion, the pulley pushes the top plate upward, and the top plate pushes out the pressed granular steel. This continuous cycle improves the efficiency of hot pressing of the granular steel. During filling, the guide pipe is continuously driven to rotate by the drive mechanism. The rotation of the guide pipe greatly reduces the probability and frequency of blockage, reduces the need for downtime for cleaning, and improves the continuous operation time and reliability of the equipment.

[0021] like Figure 1-3 As shown, the present invention proposes a particle steel hot pressing forming device, including a workbench 1, a frame 2, a hydraulic cylinder 3, and a guide hopper 8. The frame 2 is connected to the top of the workbench 1, the hydraulic cylinder 3 is set on the frame 2 with its telescopic rod pointing vertically downward, and a pressing block 31 is connected to the bottom end of the hydraulic cylinder 3. The guide hopper 8 is connected to the left side of the frame 2. The device is characterized by a turntable 4, multiple top plates 6, and protrusions 7. The turntable 4 has multiple pressing grooves, and the multiple top plates 6 are respectively slidably arranged in the multiple pressing grooves. The bottom end of each of the multiple top plates 6 is connected to a pulley 61. The bottom end of the turntable 4 has an annular groove that communicates with the multiple pressing grooves. The protrusions 7 are connected to the top of the workbench 1. The discharge end of the guide hopper 8 is inclined and rotatably provided with a guide pipe 81. A drive mechanism for driving the guide pipe 81 to rotate is provided on the front side of the guide hopper 8. A rotation mechanism for driving the turntable 4 to rotate is provided at the bottom end of the workbench 1.

[0022] In this utility model, the frame 2 is fixedly connected to the top of the workbench 1. The workbench 1 is made of a square plate and a semi-circular plate fixedly connected. Multiple pressing grooves of the same size are opened on the turntable 4. When the material passes through the guide pipe 8, the drive mechanism drives the guide pipe 8 to rotate continuously to prevent the material from sticking when it is discharged. After the material falls into the pressing groove, the hydraulic cylinder 3 presses down the pressing block 31 to press the material in the pressing groove. Then the turntable 4 continues to rotate. When the internal pulley 61 passes the protrusion 7, the protruding part of the protrusion 7 pushes the pulley 61 and the top plate 6 upward to push the material out.

[0023] In an optional embodiment, the bump 7 is arc-shaped, with low sides and high center.

[0024] In an optional embodiment, pulley 61 is slidably connected to the top of worktable 1 and the outer surface of protrusion 7.

[0025] In an optional embodiment, the drive mechanism includes a fixed frame 91, a motor 92, a worm 93, and a worm wheel 94. The fixed frame 91 is inclinedly connected to the front side of the guide hopper 8 and has the same inclination angle as the guide pipe 81. The motor 92 is located on the front side of the fixed frame 91. One end of the worm 93 is coaxially connected to the output shaft of the motor 92, and the other end is rotatably connected to the rear side wall of the fixed frame 91. The worm wheel 94 is coaxially fixedly sleeved on the guide pipe 81 and meshes with the worm 93.

[0026] It should be noted that the tilt angle of the fixed frame 91 is the same as the tilt angle of the guide tube 81.

[0027] In an optional embodiment, the rotating mechanism includes a rotating cylinder 51 and a rotating shaft 52. A support frame is connected to the bottom end of the worktable 1. The rotating cylinder 51 is disposed on the bottom wall of the support frame. One end of the rotating shaft 52 is coaxially and fixedly connected to the output shaft of the rotating cylinder 51, and the other end is connected to the bottom end of the turntable 4.

[0028] It should be noted that, since the rotating cylinder 51 drives the rotating shaft 52 to rotate intermittently, the time spent therein can be used for filling, pressing and pushing the material.

[0029] In an optional embodiment, a scraper 10 is connected to the front side of the platform 2, with its bottom end close to the top of the turntable 4.

[0030] It should be noted that by setting the scraper 10 to be close to the surface of the turntable 4, the metal particles that fall out during the filling process are pushed into the pressing groove when the turntable 4 rotates, thus reducing material waste.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
