Description

Technical Field

[0001] This application relates to the field of shaping apparatus technology, and in particular to a shaping apparatus for sintering gear processing. Background Technology

[0002] Powder metallurgy gears are characterized by low production cost, self-lubrication, and mass production. After the initial forming of the gear, sintering and shaping processes are carried out. Usually, the shaping process involves placing the sintered gear into a gear mold and pressing it against the upper and lower molds to complete the shaping. During the shaping process, the sintered gear is usually transferred by the operator and then placed into the gear mold of the shaping device for stamping and shaping. Afterward, the operator removes the shaped gear. Because there are too many gears to be shaped, the operator has to perform repetitive actions. When the operator works for a long time, fatigue will occur, which will affect subsequent work and result in low gear processing efficiency. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings and deficiencies of the existing technology by providing a shaping device for sintered gear processing.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: The device includes a hydraulic press and a forming mold, with the forming mold located inside the hydraulic press. It also includes a transfer assembly, a loading frame, and a unloading frame. The transfer assembly is located on one side of the hydraulic press, while the loading frame and the unloading frame are located on corresponding sides of the hydraulic press. The transfer assembly includes a propulsion cylinder, a lifting cylinder, a propulsion plate, a first suction pipe, and a second suction pipe. The first and second suction pipes are respectively inserted and installed at both ends of the propulsion plate. One end of the propulsion plate is located at the output end of the propulsion cylinder, and the propulsion cylinder is located at the output end of the lifting cylinder. Under the action of the propulsion cylinder and the lifting cylinder, the first suction pipe transfers the gear in the loading frame to the forming mold, while the second suction pipe transfers the gear in the forming mold to the unloading frame.

[0005] Preferably, the side wall of the push plate is provided with a sliding groove, and a sliding plate is inserted and slidably in the sliding groove. The first suction tube is inserted into one end of the sliding plate, and the other end of the sliding plate is provided with a stabilizing component. The stabilizing component includes a stabilizing block and a stabilizing cylinder. The stabilizing cylinder is located on the sliding plate, and the stabilizing block is located at the output end of the stabilizing cylinder. The side wall of the push plate is provided with an adjusting cylinder, which can slide the sliding plate in the sliding groove.

[0006] Preferably, the lower end of the stabilizing block is provided with a protective soft sleeve.

[0007] Preferably, a transport component is provided between the unloading frame and the hydraulic press. Under the action of the push cylinder and the lifting cylinder, the first suction pipe transfers the gear in the loading frame to the transport component, and the transport component transports the gear to the unloading frame.

[0008] Preferably, the sidewall of the feeding frame is provided with cushioning sponge.

[0009] Preferably, the transfer assembly further includes a support plate, the side wall of the push plate is provided with a trapezoidal slide bar, and the side wall of the support plate is provided with a trapezoidal groove for the trapezoidal slide bar to slide into.

[0010] Preferably, the forming mold includes an upper template and a lower template. The upper end face of the lower template has a toothed groove. An ejection device is provided inside the lower template. The ejection device includes an ejection cylinder and an ejection rod. The ejection rod is inserted and slidably moved in the bottom of the toothed groove. One end of the ejection rod is located at the output end of the ejection cylinder.

[0011] In summary, the beneficial technical effects of this application are as follows: 1. When sintered gears need to be shaped, multiple untreated gears are placed in the loading frame. Then, the lower end of the first suction tube adsorbs the gear in one end of the loading frame. Then, under the action of the push cylinder and the lifting cylinder, the gear in the loading frame is transferred to the tooth groove of the shaping mold. At the same time, the second suction tube adsorbs the shaped gear in the tooth groove of the shaping mold. After that, the gear can be transferred from the tooth groove of the shaping mold to the transport component. Then, the transport component transports the gear to the unloading frame. In the whole process, the sintered gears are shaped automatically, which improves the work efficiency of shaping sintered gears. 2. When the first suction tube transfers the gear from the feeding frame to the tooth groove of the forming mold, the adjusting cylinder drives the sliding plate to slide in the sliding groove so that the stabilizing block corresponds to the tooth groove of the forming mold. Then the stabilizing cylinder pushes the stabilizing block into the tooth groove, so that the gear is pressed at the bottom of the tooth groove, which facilitates the subsequent forming mold to shape the sintered gear.
