Description

Technical Field

[0001] This utility model relates to the technical field of powder metallurgy die casting equipment, specifically to a powder casting billet turning and material handling device. Background Technology

[0002] refer to Figure 1 As shown, powder metallurgy is a process technology that uses metal powders (or mixtures of metal and non-metal powders) as raw materials to manufacture metallic materials, composite materials, and various types of products through forming and sintering. The formed powder casting billet A is ejected from the mold cavity B into the slide C, and then slides from slide C onto the turntable D. The billet A is then manually moved to the material tray E using tools for the subsequent sintering process. This method is complex, requires a large area, and necessitates manual intervention.

[0003] Meanwhile, the blanks pressed out by powder casting will have some dust residue. After the dust remains on the surface of the blank and sinters, it will affect the surface quality of the product. At this time, it is necessary to manually blow the dust with a brush or air gun, which is inefficient and harmful to human health. Utility Model Content

[0004] In view of the existing technical problems, this utility model provides a powder casting billet turning and material handling device to solve the problems in the prior art.

[0005] In order to achieve the above-mentioned utility model objectives, the present utility model provides the following technical solution: a powder casting billet turning and picking device, characterized in that: it includes a conveyor belt (1) and a turning and picking component (4), wherein: the conveyor belt (1) conveys the powder casting billet under the drive of the transmission component (2), and the transmission component (2) is installed on the mounting frame (3);

[0006] The flipping material handling component (4) is installed at the front of the mounting frame (3). The material handling component (41) of the flipping material handling component has lifting, flipping and forward and backward movement functions. The forward and backward movement direction of the material handling component (41) is consistent with the conveying direction of the conveyor belt (1). When the material handling component (41) moves forward to the front of the conveyor belt (1), it grabs the powder casting blank and shakes off the residual dust by flipping the powder casting blank. Then it moves backward to the top of the conveyor belt (1) and finally places the powder casting blank on the conveyor belt (1) and moves backward with the conveyor belt.

[0007] The flipping and picking assembly (4) includes a finger cylinder (42) and a lifting cylinder (46), wherein: the finger cylinder (42) is coaxially fixedly connected to the output shaft of the flipping drive component (43), and the two movable ends of the finger cylinder (42) are provided with the picking component (41) for gripping the blank, which is a gripping block; the flipping drive component (43) is arranged side by side above the front and rear moving drive component (44), both facing forward and horizontally, and a lifting cylinder (45) is vertically arranged between the flipping drive component (43) and the front and rear moving drive component (44); the upper end of the piston rod of the lifting cylinder (45) is fixedly connected to the flipping drive component (43) through the first connecting plate (46), and the outer shell of the lifting cylinder (45) is fixedly connected to the piston rod of the front and rear moving drive component (44) through the second connecting plate (47), and the front and rear moving drive component (44) is fixed on the mounting frame (3) through the mounting plate; the flipping drive component (43) is a motor, and the front and rear moving drive component (44) is a cylinder.

[0011] In this embodiment, the flipping drive component (43) is driven by a stepper motor and the gearbox is fixedly connected to the finger cylinder (42) through a coupling and a connecting shaft.

[0012] In this case, the transmission assembly (2) includes a drive wheel (2a) and a driven wheel (2b), both of which are rotatably mounted on the mounting bracket (3). The drive wheel (2a) is coaxially connected to the output shaft of the transmission motor (2c) and rotates under the drive of the transmission motor (2c).

[0013] Beneficial effects: This utility model can replace the existing slide and turntable, directly grabbing the powder casting blank and placing it directly on the material tray; at the same time, this utility model can flip and shake off the dust after grabbing the powder casting blank, which not only avoids the dust remaining on the surface of the powder casting blank and affecting the surface quality of the product after sintering, but also avoids manual dust blowing.

[0018] The present invention will be further described in detail below with reference to experimental examples and specific embodiments. However, this should not be construed as limiting the scope of the above-mentioned subject matter of the present invention to the following embodiments. All technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0019] Example 1

[0020] As attached Figures 2-4 The illustrated powder casting billet tilting and retrieving device comprises a conveyor belt 1, a transmission assembly 2, a mounting frame 3, and a tilting and retrieving assembly 4. The conveyor belt 1, driven by the transmission assembly 2, transports the powder casting billet A from front to back, placing the billet A onto a material tray. The transmission assembly 2 is mounted on the mounting frame 3. In this embodiment, the transmission assembly 2 includes a driving wheel 2a and a driven wheel 2b, both rotatably mounted on the mounting frame 3. The driving wheel 2a is coaxially connected to the output shaft of a drive motor 2c and rotates under the drive of the drive motor 2c.

[0021] The flipping and picking assembly 4 is installed at the front of the mounting frame 3. The picking component 41 of this assembly has lifting, flipping, and forward / backward movement functions, and the forward / backward movement direction of the picking component 41 is consistent with the conveying direction of the conveyor belt 1. When the picking component 41 moves forward to the front of the conveyor belt 1, it picks up the powder casting blank, flips it to shake off residual dust, and then moves backward directly above the conveyor belt 1, finally placing the powder casting blank on the conveyor belt 1. The powder casting blank then moves backward along with the conveyor belt. In this case, the forward movement of the picking component 41 is controlled by a program setting, which is existing technology. If the powder casting blank is directly above the conveyor belt 1 when flipping to shake off residual dust, the shaken dust will still move backward with the conveyor belt 1. When the powder casting blank is placed on the conveyor belt 1 and moves backward, it will re-adhere to the dust, thus rendering the dust-shaking action meaningless.

[0022] In this utility model, the flipping material handling component 4 has various structural forms to meet the functional requirements. Here is a brief introduction to several commonly used structural forms. In actual application, it is not limited to these structural forms.

[0023] In this embodiment, the flipping and picking assembly 4 includes a finger cylinder 42 and a lifting cylinder 46, wherein: the finger cylinder 42 is coaxially and fixedly connected to the output shaft of the flipping drive component 43. The two movable ends of the finger cylinder 42 are provided with picking components 41 for gripping the blank, which are gripping blocks, and these two gripping blocks are fixedly connected to the finger cylinder 42. The flipping drive component 43 is arranged horizontally and side-by-side above the front-rear moving drive component 44, both facing forward. A lifting cylinder 45 is vertically arranged between the flipping drive component 43 and the front-rear moving drive component 44; the upper end of the piston rod of the lifting cylinder 45 is fixedly connected to the flipping drive component 43 through a first connecting plate 46, and the outer shell of the lifting cylinder 45 is fixedly connected to the piston rod of the front-rear moving drive component 44 through a second connecting plate 47. The front-rear moving drive component 44 is fixed to the mounting frame 3 through a mounting plate. The lifting cylinder 45 is connected to the mounting frame 3 via a guide rail slider assembly, ensuring that the lifting cylinder 45 moves linearly under the action of the forward and backward movement drive component 44 without swaying. The finger cylinder 42 is horizontally positioned directly above the conveyor belt 1. In this embodiment, the flipping drive component 43 is a motor, and the forward and backward movement drive component 44 is a cylinder.

[0024] In this structural configuration, when the forward and backward moving drive component 44 operates, it drives the lifting cylinder 45, the tilting drive component 43, and the finger cylinder 42 to move forward and backward together. When the lifting cylinder 45 operates, it drives the tilting drive component 43 and the finger cylinder 42 to rise and fall together. The finger cylinder 42 uses two material-grabbing components 41 to pick up the powder casting blank A and tilts it around the axis of the finger cylinder 42 to shake off residual dust. The tilting angle of the powder casting blank A around the axis of the finger cylinder 42 must be sufficient to shake off the residual dust, and the tilting angle is controlled and implemented according to the existing program.

[0025] During operation, the finger cylinder 42 first moves backward to the front of the conveyor belt 1, and then moves downward to pick up the powder casting blank A through the two material picking components 41. Then, the powder casting blank A is flipped over to shake off the residual dust on the powder casting blank A. Then, it moves backward to the top of the conveyor belt 1 and moves downward for a certain distance. Then, the two material picking components 41 release the powder casting blank A. Under the action of gravity, the powder casting blank A falls onto the conveyor belt 1 and moves backward with the conveyor belt 1. Finally, it moves to the material tray E.

[0027] In this embodiment, the forward and backward movement drive component 44 is a servo motor. The actuator of the servo motor is fixedly connected to the housing of the lifting cylinder 45 via the second connecting plate 47, thereby driving the lifting cylinder 45 to move linearly in the forward and backward direction. The other structures of this embodiment are exactly the same as those of Embodiment 1, and will not be described again here.

[0028] Example 3

[0029] In this embodiment, the forward and backward movement drive component 44 adopts a structure in which a stepper motor drives a ball screw and a slider. The slider is fixedly connected to the housing of the lifting cylinder 45 through a second connecting plate 47, thereby driving the lifting cylinder 45 to move linearly in the forward and backward direction. The other structures of this embodiment are exactly the same as those of Embodiment 1, and will not be described in detail here.

[0030] Example 4

[0031] In this embodiment, the flipping drive component 43 is a servo motor, and the actuator of the servo motor is fixedly connected to the finger cylinder 42, thereby driving the finger cylinder 42 to rotate around its axis. The other structures of this embodiment are exactly the same as those of Embodiment 1, and will not be described in detail here.

[0032] Example 5

[0033] In this embodiment, the flipping drive component 43 uses a stepper motor to drive a reduction gearbox. The output shaft of the reduction gearbox is coaxially and fixedly connected to the finger cylinder 42 via a coupling and a connecting shaft. The stepper motor drives the finger cylinder 42 to rotate around its axis. The other structures in this embodiment are exactly the same as in Embodiment 1, and will not be described again here.
