Description

Technical Field

[0001] This utility model relates to the field of powder metallurgy equipment technology, and specifically discloses a feeding device for a powder metallurgy forming machine. Background Technology

[0002] Powder metallurgy is a process technology that uses metal powders as raw materials to manufacture metal materials, composite materials, and various types of products through compression molding. When metal powders are compressed, a powder metallurgy molding machine is required. Currently, traditional powder metallurgy molding machines, after pressing the product, lack a matching unloading device, requiring manual removal of the molded product from the machine for transfer and sintering.

[0003] The feeding device of a powder metallurgy forming machine has a large impact force when feeding the formed products, which can easily cause scratches on the surface of the formed products. In addition, a large number of products accumulate during feeding, causing them to be squeezed and deformed, which affects the product quality. Therefore, a feeding device for a powder metallurgy forming machine is needed to solve this problem. Utility Model Content

[0004] This utility model proposes a feeding device for a powder metallurgy forming machine. The buffer mechanism can reduce the impact force of the product falling, reduce scratches on the surface of the formed product, and reduce the generation of burrs. The design of the equal volume groove ensures that only one product can pass through at a time, avoiding mutual accumulation, squeezing and deformation, which would affect the quality of the formed product.

[0010] As a preferred material feeding device for a powder metallurgy forming machine according to this utility model, the buffer slide is inclined.

[0011] As a preferred material feeding device for a powder metallurgy forming machine according to this utility model, the buffer plate is made of a composite material of rubber and silicon carbide.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0023] Please see Figures 1-4 A feeding device for a powder metallurgy forming machine includes a fixed platform 1, a movable collecting platform 2 is provided above the fixed platform 1 via a horizontal drive mechanism, a rotating feeding mechanism is provided above the collecting platform 2, and a buffer mechanism is installed on the upper end face of the rotating feeding mechanism.

[0024] The rotary feeding mechanism includes a fixed cylinder 3 set above the fixed platform 1, a feed pipe and a discharge pipe coaxially opened on the upper and lower sides of the fixed cylinder 3, the outlet of the discharge pipe facing the receiving position of the collecting platform 2, a turntable 301 rotatably connected inside the fixed cylinder 3, multiple arc-shaped grooves 302 arranged in a ring array on the edge of the turntable 301, and each groove 302 having an equal volume, and a stepper motor 303 installed on the outer wall of the fixed cylinder 3, with its output end fixedly connected to the turntable 301;

[0025] The buffer mechanism includes a buffer slide 4 connected to the upper end face of the feed pipe and a buffer plate 401 embedded in the inner wall of the buffer slide 4.

[0026] In this embodiment: when the molded product enters the buffer slide 4, the buffer plate 401 can slow down the falling speed of the molded product and reduce the impact force of the product falling. In turn, the buffer mechanism can reduce scratches on the surface of the molded product and reduce the generation of burrs.

[0027] The molded products falling through the buffer slide 4 enter the fixed cylinder 3 through the feed pipe and fall into one of the grooves 302 on the turntable 301. At the same time, the stepper motor 303 drives the turntable 301 to rotate, causing the adjacent groove 302 to rotate directly below the feed pipe. The next molded product falls into the groove 302. This cycle continues until the first groove 302 rotates to align with the feed pipe. Then, the molded products in the groove 302 can fall and be collected individually through the feed pipe. The design of the equal-volume grooves 302 ensures that only one product can pass through at a time, avoiding mutual accumulation, compression and deformation, which would affect the quality of the molded products.

[0028] As a technical optimization of this utility model, the horizontal drive mechanism includes a threaded rod 101 rotatably connected inside the fixed platform 1, a servo motor 102 installed on the outer wall of the fixed platform 1 and whose output end is fixedly connected to the threaded rod 101, a sliding sleeve threadedly connected to the outer wall of the threaded rod 101 and slidably connected to the bottom end of the inner wall of the fixed platform 1, and the upper end face of the sliding sleeve is fixedly connected to the material collection platform 2.

[0029] In this embodiment: the servo motor 102 is started, which drives the threaded rod 101 to rotate, causing the sliding sleeve to move the collecting platform 2 to the left or right, so that the molded products falling from the feeding tube can fall smoothly into the material trough 201 for collection.

[0030] As a technical optimization of this utility model, the upper surface of the material collection platform 2 is provided with a plurality of equidistant material troughs 201, and the inner wall of the material troughs 201 is provided with rubber pads.

[0031] In this embodiment: the material trough 201 can be used to collect the falling molded products, and the rubber pad can prevent the molded products from colliding with the material trough 201.

[0032] As a technical optimization of this utility model, the buffer slide 4 is set at an angle.

[0033] In this embodiment, the inclined arrangement of the buffer slide 4 allows the molded product to smoothly enter the fixed cylinder 3 through the feed pipe.

[0034] As a technical optimization of this utility model, the buffer plate 401 is made of a composite material of rubber and silicon carbide.

[0035] In this embodiment, the buffer plate 401 is made of a composite material of rubber and silicon carbide, which can achieve the effects of wear resistance and cushioning.

[0036] As a technical optimization of this utility model, a fixing frame 103 for supporting the fixing cylinder 3 is fixedly connected to the outer wall of the fixing platform 1. A controller 5 is installed on the inner wall of the fixing frame 103. The stepper motor 303 and the servo motor 102 are both electrically connected to the controller 5.

[0037] In this embodiment: the stepper motor 303 and the servo motor 102 can be controlled to work normally by the controller 5, and the fixed cylinder 3 can be supported by the fixed frame 103.

[0038] The working principle and usage process of this utility model: After molding, the product slides down along the inclined buffer slide 4. The buffer plate 401 can slow down the falling speed of the molded product. The product falls into the groove 302 of the turntable 301 through the feed pipe. The stepper motor 303 drives the turntable 301 to rotate at a preset angle. When the groove 302 carrying the product rotates to the top of the feed pipe, the product falls freely onto the collection platform 2. The controller 5 controls the servo motor 102 to drive the threaded rod 101 to rotate according to the rotation speed of the turntable 301, causing the sliding sleeve to move the collection platform 2 laterally. The outlet of the feed pipe is always aligned with the center of the current empty material trough 201 of the collection platform 2 to collect the molded product.

[0039] In the description of this utility model, it should be understood that the terms "left", "right", "up", "down", "top", "bottom", "front", "back", "inner", "outer", "back", "middle", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.
