Description

Technical Field

[0001] The utility model relates to the technical field of punching machines, in particular to a powder metallurgy punching machine for gear processing. Background Art

[0002] A stamping machine, also known as a stamping die, or simply a die, is a special tool for processing metal materials or materials containing metal powder into the required stamping parts. When processing gears, a stamping machine is needed to stamp the gears to ensure that the gears meet the specified specifications.

[0003] When processing gears, a powder metallurgy stamping machine for gear processing is needed to facilitate the processing of gears. Among them, the "stamping die for powder metallurgy parts processing" disclosed in the application number "CN217095666U" has solved the various disadvantages of existing powder metallurgy forming dies, such as inconvenience in demolding, increased work intensity and reduced work efficiency.

[0004] However, there are still many defects in the actual use of stamping machines with similar structures. For example, it does not have the function of improving the stamping quality of gears, resulting in the problem that the raw materials overflowing from the gears need to be manually scraped flat by the operator, which increases the workload of the operator. The overflowing raw materials can easily cause bulges on the gears, reducing the precision of the gear stamping using the device. At the same time, it does not have the anti-adhesion function, which makes it inconvenient to demold the high-temperature gears after stamping, reducing the efficiency of gear processing. At the same time, it is not convenient for the device to operate stably for a long time, and the device needs to be shut down for cooling. Therefore, it is necessary to design a powder metallurgy stamping machine for gear processing. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a powder metallurgy punching machine for gear processing to solve the above problems.

[0006] To achieve the above purpose, the utility model is implemented through the following technical solutions: a powder metallurgy punching machine for gear processing, comprising a box body, a scraping mechanism for scraping powder metallurgy materials is fixedly installed on one side of the box body, a screw is rotatably installed on one side of the top of the box body, a moving plate is threadedly installed on the outer side of the screw, and an anti-adhesion mechanism for preventing powder metallurgy from sticking is fixedly installed on the bottom of the moving plate;

[0007] The scraping mechanism comprises a mounting seat, a uniform speed motor is fixedly mounted on one side of the mounting seat, a connecting piece is fixedly mounted on the output end of the uniform speed motor, an electric rod is fixedly mounted on one side of the connecting piece, and a scraper for scraping off the overflowed material in the powder metallurgy is fixedly mounted on the output end of the electric rod;

[0008] The anti-adhesion mechanism comprises an upper die seat, wherein a refrigeration pipe bank for cooling powder metallurgy is fixedly installed inside the upper die seat.

[0009] Preferably, a servo motor is fixedly mounted on the top of the box body, and the output end of the servo motor is fixedly connected to the bottom end of the screw rod.

[0013] Preferably, a controller is fixedly mounted on the top of the front side of the box, and a display screen is fixedly mounted on the front side of the controller.

[0014] Beneficial Effects

[0015] The utility model provides a powder metallurgy punching machine for gear processing. Compared with the prior art, it has the following beneficial effects:

[0016] 1. The connecting piece is driven to rotate by energizing the uniform speed motor. The rotating connecting piece can drive the electric rod to move in an arc shape to the specified position, and then the electric rod is energized to drive the scraper to move horizontally. The scraper moving horizontally can easily scrape the overflowed material inside the shell, so that the material inside the shell meets the subsequent stamping accuracy, thereby improving the stamping quality of the gear, avoiding the problem of the operator manually scraping the overflowed material, and reducing the workload of the operator.

[0017] 2. The radiator is powered on to generate suction to accelerate the air circulation around the heat exchange pipe, so that the heat exchange pipe is in a low-temperature state. The heat exchange pipe in the low-temperature state can then be used to cool the condensate inside the refrigeration box. The circulating pump is powered on to generate suction and the low-temperature condensate stored inside the refrigeration box is transported to the refrigeration pipe row through pipe fittings to exchange temperature with the upper die seat, so that the upper die seat is in a low-temperature state. The upper die seat in a low-temperature state can prevent the high-temperature gear raw material from sticking to the bottom of the upper die seat, thereby realizing the anti-sticking function, facilitating the subsequent demoulding of the stamped gear, and improving the efficiency of gear processing. It also facilitates the long-term stable operation of the device and avoids the need to shut down the device for cooling. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The utility model provides two technical solutions:

[0025] Figure 1 , Figure 2 , Figure 3 , Figure 4 The first embodiment is shown: a powder metallurgy punching machine for gear processing, comprising a box body 1, a scraping mechanism 2 for scraping powder metallurgy material is fixedly installed on one side of the box body 1, a screw 101 is rotatably installed on one side of the top of the box body 1, a moving plate 102 is threadedly installed on the outer side of the screw 101, and an anti-adhesion mechanism 3 for preventing powder metallurgy from sticking is fixedly installed on the bottom of the moving plate 102;

[0026] The scraping mechanism 2 includes a mounting seat 201, a uniform speed motor 202 is fixedly mounted on one side of the mounting seat 201, a connecting piece 203 is fixedly mounted on the output end of the uniform speed motor 202, an electric rod 204 is fixedly mounted on one side of the connecting piece 203, and a scraper 205 for scraping off the overflowed material in the powder metallurgy is fixedly mounted on the output end of the electric rod 204;

[0027] The anti-adhesion mechanism 3 includes an upper die base 301, and a refrigeration pipe bank 302 for cooling powder metallurgy is fixedly installed inside the upper die base 301;

[0028] A servo motor 103 is fixedly installed on the top of the box body 1, and the output end of the servo motor 103 is fixedly connected to the bottom end of the screw 101, a shell 4 is fixedly installed at the top center of the box body 1, an electric push rod 401 is fixedly installed below the shell body 4, and a support plate 402 is fixedly installed on the output end of the electric push rod 401, a hinge is fixedly installed on one side of the front of the box body 1, and a box door 5 is movably installed on one side of the hinge.

[0029] After the device is installed at the designated installation position, the operator puts the high-temperature metal powder into the interior of the finger housing 4, and then the uniform speed motor 202 is powered on to drive the connecting member 203 to rotate. The rotating connecting member 203 can drive the electric rod 204 to move in an arc to the designated position, and then the electric rod 204 is powered on to drive the scraper 205 to move in a horizontal position. The scraper 205 that moves in a horizontal position can easily scrape the overflowed material inside the housing 4, so that the material inside the housing 4 meets the subsequent stamping accuracy, thereby achieving the function of improving the stamping quality of the gear;

[0030] Then, the servo motor 103 is powered on to drive the screw 101 to rotate, and the rotating screw 101 can drive the movable plate 102 to move vertically, so that the upper die base 301 moves synchronously. The upper die base 301 that moves vertically is used in conjunction with the housing 4 to facilitate stamping of the gear.

[0031] The electric push rod 401 is powered on to drive the support plate 402 to a vertical position.
