Description

Technical Field

[0001] This utility model relates to the field of stamping device technology, specifically a stamping device for powder metallurgy. Background Technology

[0002] As is well known, oil-impregnated bearings, also known as porous bearings, use metal powder as the main raw material. Oil-impregnated bearings are sintered bodies made by powder metallurgy, which are inherently porous. Moreover, they have the technical advantages of being able to freely adjust the number, size, shape and distribution of pores during the manufacturing process.

[0003] A search revealed a Chinese patent document disclosing a mold for powder metallurgy (publication number: CN215237825U). Although the device includes a processing platform, a base frame is fixedly connected to the bottom of the processing platform, a support arm is fixedly connected to the top of the processing platform at a position slightly behind the middle, a hydraulic column is fixedly connected to the bottom of the end of the support arm away from the processing platform, an upper pressure plate is fixedly connected to the output end of the hydraulic column, a mold is placed on the top of the processing platform at a position in the middle, a stamping device is set on the top of the processing platform and on the rear side of the mold, and a connecting rod is fixedly connected to the outer left side of the mold, the connecting rod being slidably engaged with the processing platform.

[0004] While the aforementioned equipment improves processing efficiency by fixing the mold before stamping, it currently only produces molds of a single size. The inability to flexibly replace molds of different specifications not only leads to high costs but also forces manufacturers to purchase additional stamping equipment suitable for other sizes, further increasing their expenses. Moreover, traditional stamping equipment requires operators to manually handle and place the molds, but the machine's operating speed is difficult to control precisely, and even slight mistakes can easily cause hand injuries. Furthermore, if the powder enters the material tank unevenly or irregularly, it can negatively impact the quality of subsequent mold forming, reducing the product yield. Utility Model Content

[0005] The purpose of this invention is to provide a stamping device for powder metallurgy, addressing the problem mentioned in the background section that the current device can only produce molds of a single size. The inability to flexibly replace molds of different specifications not only leads to high costs but also forces manufacturers to purchase additional stamping equipment suitable for other sizes, further increasing expenses. Moreover, traditional stamping devices require operators to manually handle and place the molds, but the machine's operating speed is difficult to control precisely, and even slight errors can easily cause hand injuries to operators. Furthermore, if the powder enters the material trough unevenly or irregularly, it will negatively impact the subsequent mold-forming quality, reducing the product qualification rate.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a stamping device for powder metallurgy, comprising a base, a pushing and cleaning component fixedly connected to one side of the base surface, four first sliding rods fixedly connected to the other side of the base surface, a first air pump fixedly connected to the top between the four first sliding rods, a replacement head threadedly connected to one end of the first air pump, a sliding plate fixedly connected to the middle of the first air pump, and the four corners of the sliding plate slidably connected to the surfaces of the four first sliding rods, a tabletop fixedly connected to the middle between the four first sliding rods, and first limiting posts fixedly connected to the four corners of the tabletop.

A first cylinder is fixedly connected to the bottom of the tabletop, and the stamping is controlled by a first air pump. At the same time, the stamping head is replaceable and can be replaced by splicing through threaded holes and bolts, which is convenient for replacement during dimensional stamping. In order to protect the workers, the machine pushes instead of the action of picking up by hand. At this time, the cleaning component can be raised to push the produced mold out, and lowered to clean the powder around the mold. It can also flatten the surface inside the mold chamber.

[0007] Preferably, the pushing cleaning component includes a placement frame, the top of which is fixedly connected to two telescopic compartments, which are arranged opposite to each other. A second sliding rod is slidably connected to the middle of each of the two telescopic compartments. A connecting strip is fixedly connected to one end of each of the two second sliding rods. A fourth cylinder is fixedly connected to the bottom of the connecting strip, and one side of the connecting strip is fixedly connected to the placement frame. A second limiting post is fixedly connected to one side of the placement frame, and one end of the second limiting post is movably connected to the top of the connecting strip, facilitating material unloading and ensuring worker safety.

One end of the two telescopic rods is fixedly connected to a second crossbar, the bottom of the second crossbar is fixedly connected to a cleaning strip, and the other end of the two telescopic rods is fixedly connected to a first crossbar whose lifting and lowering can be adjusted. This allows for cleaning of powder, and when raised, it can push out the mold lifted by the first cylinder.

[0009] Preferably, a sliding groove is fixedly connected to one side of the first crossbar, a fixed column is slidably connected to one side of the sliding groove, a second connecting rod is fixedly connected to one side of the fixed column, a bracket is rotatably connected to the bottom of the second connecting rod, and the bottom end of the bracket is fixedly connected to the surface of the base to support the whole and can be discharged by the force when stamping with the base.

[0010] Preferably, a first connecting rod is fixedly connected to one side of the second connecting rod, an adjusting rod is movably connected to one end of the first connecting rod, a third cylinder is fixedly connected to one end of the adjusting rod, and a fixed seat is movably connected to one end of the third cylinder. The bottom of the fixed seat is fixedly connected to the surface of the base. The cylinder uses an existing device and has a certain supporting force.

[0011] Preferably, the mold device includes a fixed plate, a first hydraulic rod fixedly connected to one side of the fixed plate, a third plate slidably connected to the other side of the fixed plate, a second plate movably connected to one side of the third plate, a first plate movably connected to one side of the second plate, and one side of the first plate movably connected to one end of the fixed plate.

A replacement head has been added to the stamping section, allowing for flexible replacement of stamping heads of different specifications to meet diverse production needs. Simultaneously, the mold chamber is designed to be adjustable and equipped with several hydraulic rods. These hydraulic rods can be adjusted by pushing to precisely control the dimensions, facilitating the generation of molds of different sizes. For safety, a pushing and cleaning component has been added. After the mold is generated, the fourth cylinder can drive the second crossbar to smoothly push the mold out of the device, avoiding direct contact between personnel and operating equipment, effectively ensuring personnel safety. Moreover, during the powder feeding process, when the second crossbar descends, it can simultaneously push out unevenly accumulated impurities in the material trough, ensuring uniform powder distribution, thereby improving mold quality and increasing product qualification rate.
