Technical Field

[0001] The invention relates to the technical field of metal powder processing, in particular to a paving and forming device for metal powder processing. Background Art

[0002] Powder metallurgy is an industrial technology that produces metal powder or uses metal powder (or a mixture of metal powder and non-metallic powder) as raw material, and then produces metal materials, composite materials and various types of products through forming and sintering. Powder metallurgy technology has a series of advantages such as significant energy saving, material saving, excellent performance, high product precision and good stability. It is very suitable for mass production. The basic process of powder metallurgy technology is to form powder into a blank of the desired shape. The purpose of forming is to obtain a compact of a certain shape and size, and to make it have a certain density and strength.

[0003] When metal powder is die-casted, a metal powder forming machine is generally required. The forming machine places metal powder into a lower die and presses the upper die toward the lower die through a hydraulic press to form the metal powder. During the metal powder filling process, the metal powder is filled unevenly, which will cause the performance of the molded part to differ in different parts. During use, due to the different forces and working environments in various parts, it is easy to cause partial premature failure of the molded part, thereby reducing the reliability and service life of the entire product. Summary of the invention

[0005] A support assembly, wherein the support assembly is fixedly mounted on the top of the platform, and the support assembly and the cylinder are located on the same vertical plane;

[0006] A pressure assembly, the pressure assembly is fixedly mounted on the output end of the cylinder, and the output end of the cylinder passes through the support arm;

[0007] Wherein, the supporting assembly comprises a connecting plate, and the connecting plate is fixedly connected to the platform through a connecting fastener on the outer side of the connecting plate, a round rod is fixedly connected to the middle of the top of the connecting plate, and a round ball is fixedly connected to the end of the round rod away from the connecting plate, and an elastic rope is fixedly connected to the top of the connecting plate. In the initial state, the elastic rope is in a taut state, and the module is in a horizontal state under the action of the elastic force of multiple elastic ropes distributed at the edge of the module and the supporting force of the round rod, so that the module can be adjusted to a horizontal level and improve the working stability of the equipment. When working, metal powder is added to the inner cavity of the module. Due to the uneven distribution of the added metal powder, the force on each part of the module is different. Therefore, under the action of the gravity of the metal powder, the module rotates around the round ball and The tilt occurs, causing the elastic rope tilted downward to loosen, so that the module is not under force on that side, and the elastic rope on the other side is stretched and tightened. Under the action of the elastic ropes at both ends, the module is reset and tilted in the opposite direction, so that the powder on the side with more metal powder moves to the side with less metal powder. The uneven distribution of the metal powder itself causes inconsistent gravity, and the module is shaken in multiple directions under the action of the elastic ropes, so that the metal powder inside the module is filled evenly, avoiding uneven filling of the powder in the mold, and the difference in bonding strength between different layers during the pressing process. It can also avoid damage or falling off at the edge or corner of the pressed blank.

During operation, after the metal powder is evenly filled, the cylinder drives the pressure component to move downward to press the metal powder inside the module, so that the metal powder is pressed from top to bottom at the same time, thereby improving the strength of the pressing, and allowing the entire pressing and unloading to be completed in one piece, thereby reducing the time for pressing and improving efficiency. The circular plate is slidably connected to the inner wall of the module, and one end of the circular plate close to the compression spring is fixed Connect a limiting block. During the process of filling metal powder, the module shakes under the action of the gravity of the metal powder and the elastic force of the elastic rope. By setting the limiting block, the circular plate is prevented from tilting on the inner wall of the module. The limiting block is located on the side of the circular plate close to the module. The bottom of the module is fixedly connected with a base. A circular groove is provided at the bottom of the base. A ball is located inside the circular groove. The inner wall of the circular groove is rotatably connected to the ball. The outer side of the module is fixedly connected with a limiting rod.

During operation, after the metal powder is filled evenly, the cylinder drives the fixed rod to move downward, and the fixed rod drives the punch to press the metal powder inside the module, and at the same time, the fixed rod drives the shell to move downward, so that the shell passes through the gap between the protective frame and the module and contacts the limiting rod. The limiting cooperation between the shell and the limiting rod can prevent the module from tilting during the pressing and molding process. At the same time, the sliding frame contacts the fixed block. As the sliding frame and the Under the extrusion between the fixed blocks, the sliding frame drives the cleaning plate away from the punch. After the pressing is completed, the cylinder drives the shell away from the module, and the sliding frame separates from the fixed block. Under the mutual suction force between the sliding frame and the punch, the sliding frame drives the cleaning plate to clean the punch to avoid residual powder on the outside of the punch. A sliding groove is provided on the outside of the punch, and a connecting rod is slidably connected to the inner wall of the sliding groove. The end of the connecting rod away from the punch is fixedly connected to the shell, and the shell is slidably connected to the punch.

DETAILED DESCRIPTION

[0027] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0028] The first embodiment, as Figures 1 to 5 As shown, the present invention provides a technical solution: a paving and forming device for metal powder processing, comprising a platform 1, a vertical plate 2 is fixedly connected to the top of the platform 1, a support arm is arranged on the outer side of the vertical plate 2, and a cylinder 4 is fixedly connected to the top of the support arm;

[0029] Support assembly 3, support assembly 3 is fixedly mounted on the top of platform 1, and support assembly 3 and cylinder 4 are located on the same vertical plane;

[0030] A pressure assembly 5, the pressure assembly 5 is fixedly mounted on the output end of the cylinder 4, and the output end of the cylinder 4 passes through the support arm;

[0031] Among them, the supporting assembly 3 includes a connecting plate 31, which is fixedly connected to the platform 1 through a connecting fastener on the outside of the connecting plate, a round rod 33 is fixedly connected to the middle of the top of the connecting plate 31, and a round ball 37 is fixedly connected to the end of the round rod 33 away from the connecting plate 31, and an elastic rope 35 is fixedly connected to the top of the connecting plate 31. In the initial state, the elastic rope 35 is in a taut state. Through the elastic force of multiple elastic ropes 35 distributed at the edge of the module 361 and the supporting force of the round rod 33, the module 361 is in a horizontal state. The level of the module 361 can be adjusted to improve the working stability of the equipment. When working, metal powder is added to the inner cavity of the module 361. Due to the uneven distribution of the added metal powder, the force on each part of the module 361 is different. Therefore, under the gravity of the metal powder, the module 361 revolves around the round ball 37 rotates and tilts, causing the elastic rope tilted downward to loosen, so that the side of the module 361 is not subjected to force, and the elastic rope 35 on the other side is stretched and tightened. Under the action of the elastic ropes 35 at both ends, the module 361 is reset and tilted in the opposite direction, so that the powder on the side with more metal powder moves to the side with less metal powder. By utilizing the uneven distribution of the metal powder itself and the inconsistent gravity, the module 361 is shaken in multiple directions under the action of the elastic ropes 35, so that the metal powder inside the module 361 is evenly filled, thereby avoiding uneven filling of the powder in the mold, the difference in bonding strength between different layers during the pressing process, and the damage or falling off of the edge or corner of the pressed blank. The end of the elastic rope 35 away from the connecting plate 31 is fixedly connected to the mold 36, and the mold 36 is rotatably connected to the ball 37.

[0032] There are multiple elastic ropes 35, and the multiple elastic ropes 35 are evenly distributed around the round rod 33. The top of the connecting plate 31 is fixedly connected to the protective frame 34, and the mold 36 is located in the middle of the protective frame 34. During operation, under the gravity of the metal powder, the module 361 rotates around the ball 37 and tilts. The extension ring and the limit rod 366 set on the protective frame 34 can prevent the module 361 from excessively tilting, and prevent the metal powder inside the module 361 from splashing into the inner cavity of the module 361 when tilted. An extension ring is provided on the top of the protective frame 34 close to the mold 36. The top of the protective frame 34 is fixedly connected to a fixed block 32, and the side of the fixed block 32 away from the protective frame 34 is tilted. There are multiple fixed blocks 32, and the multiple fixed blocks 32 are evenly distributed around the center of the mold 36.

[0033] The second embodiment is based on the first embodiment. Figure 6As shown, the mold 36 includes a module 361, the bottom edge of the module 361 is fixedly connected to the elastic rope 35, the inner wall of the module 361 is fixedly connected to a compression spring 362, and the end of the compression spring 362 away from the module 361 is fixedly connected to a circular plate 363. During operation, after the metal powder is evenly filled, the cylinder 4 drives the pressure component 5 to move downward to press the metal powder inside the module 361, so that the metal powder is pressed from top to bottom at the same time, thereby improving the strength of the pressing, and completing the entire pressing and unloading in one piece, thereby reducing the time for pressing and improving efficiency. The circular plate 363 is slidably connected to the inner wall of the module 361, and the end of the circular plate 363 close to the compression spring 362 is fixedly connected to a limiting block 364. During the process of filling metal powder, module 361 shakes under the action of the gravity of the metal powder and the elastic force of the elastic rope 35. A limit block 364 is set to prevent the circular plate 363 from tilting on the inner wall of the module 361. The limit block 364 is located on the side of the circular plate 363 close to the module 361. The bottom of the module 361 is fixedly connected to a base 365. A circular groove 367 is provided at the bottom of the base 365. The ball 37 is located inside the circular groove 367. The inner wall of the circular groove 367 is rotatably connected to the ball 37. The outer side of the module 361 is fixedly connected to a limit rod 366. The limit rod 366 is located on the inner wall of the protective frame 34. There are multiple limit rods 366, and the multiple limit rods 366 are evenly distributed around the module 361.

[0034] The third embodiment is based on the first and second embodiments. Figures 7 to 9As shown, the pressure assembly 5 includes a fixed rod 51, the top of which is fixedly connected to the output end of the cylinder 4, a punch 52 is slidably connected to the outer side of the fixed rod 51, the bottom of the fixed rod 51 is located in the inner cavity of the punch 52, and a return spring 57 is fixedly connected to the inner wall of the punch 52, one end of the return spring 57 is fixedly connected to the bottom of the fixed rod 51, and the return spring 57 is located inside the punch 52. During operation, after the metal powder is filled evenly, the cylinder 4 drives the fixed rod 51 to move downward, and the fixed rod 51 drives the punch 52 to press the metal powder inside the module 361. At the same time, the fixed rod 51 drives the shell 53 to move downward, so that the shell 53 passes through the gap between the protective frame 34 and the module 361 and contacts the limiting rod 366. The limiting cooperation between the shell 53 and the limiting rod 366 can prevent the module 361 from tilting during the pressing and molding process. At the same time, the sliding frame 54 contacts the fixed block 32. As the sliding frame 54 and the fixed block 32 move, the sliding frame 54 moves downward. Under the extrusion between the punch 52 and the housing 53, the sliding frame 54 drives the cleaning plate 55 away from the punch 52. After the pressing is completed, the cylinder 4 drives the shell 53 away from the module 361, and the sliding frame 54 is separated from the fixed block 32. Under the mutual suction between the sliding frame 54 and the punch 52, the sliding frame 54 drives the cleaning plate 55 to clean the punch 52 to avoid residual powder on the outside of the punch 52. A slide groove 58 is provided on the outside of the punch 52, and a connecting rod 56 is slidably connected to the inner wall of the slide groove 58. The end of the connecting rod 56 away from the punch 52 is fixedly connected to the housing 53. The housing 53 is slidably connected to the punch 52. The outer side of the housing 53 is slidably connected to the sliding frame 54. The sliding frame 54 is magnetic, and the outer side of the punch 52 is magnetic. The magnetism between the punch 52 and the sliding frame 54 is opposite. The sliding frame 54 passes through the housing 53. The end of the sliding frame 54 close to the punch 52 is fixedly connected to the cleaning plate 55. The housing 53 is located above the gap between the protective frame 34 and the module 361.

[0035] When in use, metal powder is added to the inner cavity of module 361. Due to the uneven distribution of the added metal powder, the force applied to each part of module 361 is different. Therefore, under the action of the gravity of the metal powder, module 361 rotates around the sphere 37 and tilts, causing the elastic rope tilted downward to loosen, and then this side of module 361 is not subject to force. Subsequently, the elastic rope 35 on the other side is stretched tight, and under the action of the elastic ropes 35 at both ends, module 361 is reset and tilted in the opposite direction, so that the powder on the side with more metal powder moves to the side with less metal powder. The uneven distribution of the metal powder itself leads to inconsistent gravity, and the module 361 is shaken in multiple directions under the action of the elastic ropes 35, so that the metal powder inside the module 361 is evenly filled.

[0036] After the metal powder is filled evenly, the cylinder 4 drives the fixed rod 51 to move downward, and the fixed rod 51 drives the punch 52 to press the metal powder inside the module 361. At the same time, the fixed rod 51 drives the shell 53 to move downward, so that the shell 53 passes through the gap between the protective frame 34 and the module 361 and contacts the limiting rod 366. The limiting cooperation between the shell 53 and the limiting rod 366 can prevent the module 361 from tilting during the pressing process. At the same time, the sliding frame 54 contacts the fixed block 32. With the extrusion between the sliding frame 54 and the fixed block 32, the sliding frame 54 drives the cleaning plate 55 away from the punch 52. After the pressing is completed, the cylinder 4 drives the shell 53 away from the module 361, and the sliding frame 54 is separated from the fixed block 32. Under the mutual suction between the sliding frame 54 and the punch 52, the sliding frame 54 drives the cleaning plate 55 to clean the punch 52 to avoid residual powder on the outside of the punch 52.
