[0002] Powder metallurgy is a process for manufacturing metal parts by powder pressing and sintering. It uses metal powder or a mixture of metal and non-metal powder as raw materials to manufacture various materials and parts through forming and sintering processes. This technology has many unique advantages and occupies an important position in materials science and industrial manufacturing.

[0003] When transferring the finished cylindrical metal, it is usually adsorbed by a robot with an electromagnet and placed lightly on a ceramic or graphite tray. The tray is placed on a trolley, and then the trolley with the tray is pushed to transfer the processed metal column.

[0004] However, when the cart is transporting products, the transfer material cart will shake when encountering bumpy roads, and the cylindrical metal parts are prone to rolling. The newly produced metal columns are relatively fragile, and adjacent metal columns will be scratched and damaged when they collide, causing damage to the surface of the metal parts and affecting product quality.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1-Figure 4 As shown, a powder metallurgy material cart includes a bottom plate 1, a plurality of universal wheels 2 are distributed at the four corners of the bottom of the bottom plate 1, a push-pull handle 17 is connected to the side of the bottom plate 1 to facilitate pushing and pulling the material cart, and also includes a placement structure and a shock absorbing structure;

[0026] The placement structure includes a support frame 3 and a placement plate 5. A plurality of slide rails 4 are symmetrically fixedly arranged on both sides of the support frame 3. A connecting plate 12 is arranged on both sides of the placement plate 5. The connecting plate 12 is slidably connected to the corresponding slide rail 4. The placement plate 5 is slidably connected to the corresponding slide rail 4 through the connecting plate 12. A plurality of placement grooves 6 are distributed on the top of the placement plate 5. The support frame 3 is located above the bottom plate 1.

[0027] The shock-absorbing structure is arranged between the supporting bracket 3 and the base plate 1, and the shock-absorbing structure includes a damping rod 7 and a return spring 8. There are a plurality of damping rods 7 and a plurality of return springs 8. The damping rods 7 and the return springs 8 are vertically distributed between the supporting bracket 3 and the base plate 1. The damping rod 7 has a shock-absorbing function. The return spring 8 is sleeved on the outer side of the corresponding damping rod 7. The rebound force of the return spring 8 can enhance the return function of the damping rod 7. Auxiliary shock-absorbing components are arranged at the four corners between the supporting bracket 3 and the base plate 1. The damping rod 7 and the return spring 8 absorb the vibration force exerted on the metal column during transportation, thereby avoiding collision of the metal column and affecting the appearance.

[0028] In some specific embodiments, such as Figure 2 or Figure 3As shown, in order to further enhance the shock-absorbing effect on the metal column, each group of auxiliary shock-absorbing components includes a slide groove 9, a slider 10 and a rotating rod 11. The slide groove 9 is opened at the top of the base plate 1, and a sliding rod is fixed on the inner side of the slide groove 9 along the long direction of the slide groove 9. The sliding rod is sleeved on the outer side of the sliding rod, and a shock-absorbing spring is sleeved on the end of the outer side of the sliding rod away from the slider 10. One end of the rotating rod 11 is hingedly connected to the top of the slider 10, and the other end of the rotating rod 11 is hingedly connected to the bottom of the supporting bracket 3. When encountering a bumpy road section, the base plate 1 vibrates the supporting bracket 3, and the slider 10 squeezes the shock-absorbing spring along the direction of the slider to achieve a buffering effect, thereby further enhancing the buffering effect on the supporting bracket 3.

[0029] In some specific embodiments, such as Figure 4 As shown, in order to enhance the high temperature resistance of the placement plate 5, the placement plate 5 is made of ceramic or graphite plate, and a plurality of heat dissipation holes 14 are vertically distributed on the bottom of the placement groove 6. Both ceramic and graphite plate have high temperature resistance, so as to avoid the newly processed metal column from damaging the placement plate 5. The setting of the heat dissipation holes 14 facilitates the heat dissipation of the metal column with temperature.

[0030] In some specific embodiments, such as Figure 4 As shown, in order to further enhance the limiting effect of the placement groove 6, a convex strip 13 is fixedly provided between every two adjacent placement grooves 6, and the upper surface of the convex strip 13 is provided with a rounded corner, which enhances the limiting function while preventing the convex strip 13 from scratching the metal column.

[0031] In some specific embodiments, such as Figure 2 As shown, in order to facilitate the shock absorption of the placement plate 5, a shock absorbing pad 16 is provided between each slide rail 4 and the bottom of the placement plate 5. The shock absorbing pad 16 is fixedly connected to the slide rail 4. The shock absorbing pad 16 absorbs the shock of the placement plate 5 to prevent the metal column from being damaged by bumps and vibrations.

[0032] In some specific embodiments, such as Figure 2 As shown, in order to prevent the metal column from falling from the side, baffles 15 are provided on both sides of the support bracket 3 to prevent the metal column from rolling from the placement groove 6 to the ground when encountering a bumpy road section.

[0033] In order to facilitate the understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution is briefly described in combination with specific application scenarios:

[0034] When the metal column is processed, a manipulator with an electromagnet is used to absorb the metal column and move it to the top of the placement groove 6 on the placement plate 5. The metal columns are placed separately by setting the placement groove 6 to avoid vibration caused by bumps on the road and rolling and collision of adjacent metal columns. Since the placement plate 5 is ceramic or graphite and has high temperature resistance, the residual heat of the metal column can avoid damaging the placement plate 5, thereby increasing the service life of the placement plate 5. By setting a convex strip 13 between every two adjacent placement grooves 6, the limiting effect on the metal column is further improved to avoid the metal column rolling out of the corresponding convex strip 13 and colliding with other metal columns when shaking, thereby damaging the finished product.

[0035] During use, when the user pushes the material cart to transport the metal column and encounters a bumpy road, the material cart shakes, causing the base plate 1 and the support bracket 3 to shake. The support bracket 3 generates pressure on the rotating rod 11 when shaking, so that the slider 10 drives the rotating rod 11 to slide toward the end away from the slider 10, and squeezes the shock-absorbing spring, and then the shock-absorbing spring drives the support bracket 3 to move upward. At the same time, the damping rod 7 cooperates with the support bracket 3 to reduce shock, thereby preventing the support bracket 3 from shaking and causing the metal column finished product to collide, causing damage to the metal processing finished product.

[0036] Several embodiments of the utility model are described in detail above, but the embodiments of the utility model are not limited thereto and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
