Description

Technical Field

[0001] This utility model relates to the field of pressing tooling technology, specifically a high-strength spherical powder pressing tooling. Background Technology

[0002] High-strength spherical powder pressing fixtures are used to press spherical powder into products with a certain shape and strength. Their working principle is as follows: an appropriate amount of high-strength spherical powder is evenly filled into the cavity of a mold. Then, a pressure application device applies gradually increasing pressure to the powder through components such as the upper mold. Under this pressure, air between the spherical powder particles is expelled, the particles move closer together and undergo plastic deformation, gradually filling all corners of the mold cavity to form a blank conforming to the shape of the mold cavity. When the pressure reaches a set value and is maintained for a certain time, the powder particles form a strong bonding force through mechanical interlocking and atomic diffusion, giving the blank a certain strength and density.

[0003] In the prior art, high-strength spherical powder is usually in a state of local accumulation or sparseness when added to the lower mold. When pressed directly, the interaction between powder particles is uneven, which easily leads to uneven density distribution in different areas of the pressed product, affecting the quality of the product. Therefore, a new structure is needed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a high-strength spherical powder pressing fixture to solve the problems mentioned in the background section. To solve these technical problems, this invention is achieved through the following technical solution:

[0005] This utility model is a high-strength spherical powder pressing tool, comprising:

[0006] A pressing assembly, comprising a lower mold, a receiving frame, a hydraulic telescopic device, and an upper mold, wherein the receiving frame is fixedly connected to the side of the lower mold, the hydraulic telescopic device is fixedly connected to the receiving frame, and the upper mold is fixedly connected to the bottom of the hydraulic telescopic device;

[0007] A spherical powder leveling assembly, comprising an L-shaped plate and a scraper, wherein the L-shaped plate is fixedly connected to the other side of the lower mold, and the scraper is movably connected to the side of the L-shaped plate.

[0008] Furthermore, the spherical powder leveling assembly also includes a threaded groove and a threaded rocker arm. The threaded groove is formed through the L-shaped plate, and the threaded rocker arm is movably connected in the threaded groove. One end of the threaded rocker arm is movably connected to a scraper.

[0009] Furthermore, the spherical powder leveling assembly also includes a strip groove and a strip rod. The strip groove is opened through both ends of the L-shaped plate, the strip rod is fixedly connected to the side of the scraper, and the strip rod is movably connected in the strip groove.

[0010] Furthermore, the spherical powder leveling assembly also includes a support plate, which is fixedly connected to the side of the lower mold, and a scraper is movably placed on the top of the support plate.

[0011] Furthermore, it also includes an auxiliary vibration assembly, which includes a vibrator. The vibrator is fixedly installed on the front side of the lower mold and is located on one side of the L-shaped plate.

[0012] Furthermore, the auxiliary vibration assembly also includes a base, side plates, a circular groove, and a guide rod. The base is firmly placed on the ground, and the side plates are fixedly connected to both sides of the base. A circular groove is opened through the side plates. The lower mold and the side of the L-shaped plate are both fixedly connected to the guide rod, and the guide rod is movably connected in the circular groove.

[0013] Furthermore, the auxiliary vibration assembly also includes a spring, which is movably sleeved on the guide rod.

[0014] This utility model has the following beneficial effects:

[0015] This invention utilizes a threaded rocker arm at the threaded groove to move a scraper on a support plate. When the scraper moves above the spherical powder accumulated in the lower mold, the threaded rocker arm is rotated again, causing the scraper to move above the spherical powder. Then, the threaded rocker arm is rotated in the opposite direction, and the scraper moves in the opposite direction simultaneously. This process is repeated to flatten the spherical powder in the lower mold, resulting in a more uniform distribution of the spherical powder. During the pressing process, the pressure on each part of the spherical powder is relatively consistent, and the interaction between the spherical powder particles is also more uniform. This improves the density uniformity of the pressed product and thus enhances the quality of the finished product.

[0016] Based on the above-mentioned beneficial effects, after the vibrator is turned on, the lower mold can be vibrated by the cooperation of the guide rod and the circular groove. This allows for the initial leveling of the excessively high parts before the spherical powder is leveled, shortening the subsequent leveling time and improving work efficiency. Furthermore, the deformation of the spring can accelerate the vibration rate of the lower mold, thereby shortening the initial leveling time. Attached Figure Description

[0031] The lower mold 101 is used to hold spherical powder. The setting of the receiving frame 102 ensures a firm connection of the hydraulic expansion joint 103. The hydraulic expansion joint 103 is used to drive the upper mold 104 to move up and down, thereby pressing and molding the spherical powder. The setting of the L-shaped plate 201 ensures the opening of the rear threaded groove 203. The scraper 202 is used to flatten the spherical powder. The scraper 202 is made of engineering plastic, which is lightweight and avoids getting stuck in the spherical powder.

[0032] The spherical powder leveling assembly also includes a threaded groove 203 and a threaded rocker 204. The threaded groove 203 is opened through the L-shaped plate 201, and the threaded rocker 204 is movably connected in the threaded groove 203. One end of the threaded rocker 204 is movably connected to the scraper 202.

[0033] The threaded groove 203 and the threaded rocker arm 204 work together to ensure the movement of the scraper 202.

[0034] The spherical powder leveling assembly also includes a strip groove 205 and a strip rod 206. The strip groove 205 is opened through both ends of the L-shaped plate 201. The strip rod 206 is fixedly connected to the side of the scraper 202. The strip rod 206 is movably connected in the strip groove 205.

[0035] The strip groove 205 and the strip rod 206 work together to limit the movement of the scraper 202 and prevent the scraper 202 from tilting.

[0036] The spherical powder leveling assembly also includes a support plate 207, with the support plate 207 fixedly connected to the side of the lower mold 101, and a scraper 202 movably placed on the top of the support plate 207.

[0037] The support plate 207 provides a location for the scraper 202.

[0038] It also includes an auxiliary vibration assembly, which includes a vibrator 301. The vibrator 301 is fixedly installed on the front side of the lower mold 101 and is located on one side of the L-shaped plate 201. The auxiliary vibration assembly also includes a base 302, a side plate 303, a circular groove 304, and a guide rod 305. The base 302 is firmly placed on the ground. The side plates 303 are fixedly connected to both sides of the base 302. The circular groove 304 is opened through the side plate 303. The guide rod 305 is fixedly connected to the side of the lower mold 101 and the L-shaped plate 201. The guide rod 305 is movably connected in the circular groove 304.

[0041] The inclusion of spring 306 ensures faster vibration rate.

[0042] Working principle: First, high-strength spherical powder is added to the lower mold 101. Then, the vibrator 301 is turned on to vibrate. With the cooperation between the guide rod 305 and the circular groove 304, the lower mold 101 is made to sway left and right. At this time, the spring 306 is deformed by force, which pushes the lower mold 101 to sway faster, filling the part of the spherical powder that has accumulated too high into the concave area. Then, the vibrator 301 is turned off. At the same time, the threaded rocker arm 204 is rotated at the threaded groove 203, which pushes the scraper 202 to move on the support plate 207. At this time, the strip rod 206 moves in the strip groove 205. When the scraper 202 moves to the lower mold... When the spherical powder accumulates above the mold 101, continue to rotate the threaded rocker 204. At this time, the scraper 202 moves above the spherical powder. Then, rotate the threaded rocker 204 in the opposite direction and move the scraper 202 in the opposite direction. Repeat the above process back and forth to flatten the spherical powder in the lower mold 101. Then, pull the scraper 202 upward until it is placed on the top of the support plate 207. At the same time, one end of the threaded rocker 204 contacts the scraper 202. Then, open the hydraulic telescopic device 103 to drive the upper mold 104 to move downward and press the spherical powder in the lower mold 101. This step improves the quality of the pressed product.
