[0032] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0033] The following is combined with Figure 1-Figure 4 A tungsten carbide powder turnover tool provided by the utility model is described in detail.

[0034] Combination Figure 1 The embodiment of the utility model provides a tungsten carbide powder turnover tool, which includes: a base 1, a barrel 2, a pneumatic butterfly valve 3 and an arch breaking component 4.

[0035] Specifically, a through hole 101 extending from top to bottom is provided on the base 1, and a plurality of rolling parts 102 are arranged on the side of the base 1; the barrel body 2 has a feed port 201 and a discharge port 202, the barrel body 2 is vertically arranged on the base 1 and the discharge port 202 is located above the through hole 101 to match the feed end of different workstations on the production line; the valve body of the pneumatic butterfly valve 3 is arranged at the discharge port 202 to open or close the discharge port 202; the arch breaking assembly 4 includes an air disc 401 and a pneumatic vibrator 402, and the air disc 401 and the pneumatic vibrator 402 are both arranged on the side wall of the barrel body 2.

[0036] That is to say, the tooling is provided with a base 1, which supports and positions the barrel 2 on one hand, and can be transported on an automated production line, such as on a conveyor roller, on the other hand, and when transported to the workstation, the base 1 can be set up on the receiving port of other equipment and automatically unloaded through the cooperation of the pneumatic butterfly valve 3 and the arch-breaking component 4, so that the tooling is suitable for the turnover of tungsten carbide powder on an automated production line. As for the arch-breaking component 4, due to the material characteristics of tungsten carbide powder, it is easy to arch, and different grades of materials have different arch-breaking effects due to differences in fluidity. The arch-breaking component 4 uses an air disc 401 and a pneumatic vibrator 402 to meet the unloading of different grades of tungsten carbide powder, especially grades of tungsten carbide powder with poor fluidity.

[0037] Therefore, according to a tungsten carbide powder turnover tooling of an embodiment of the utility model, through the arrangement of the through hole 101 and the rolling member 102 on the base 1 and the automatic switch outlet 202 of the pneumatic butterfly valve 3, the tooling can be applied to a fully automated production line without manual operation, and the arrangement of components such as the rolling member 102 makes the tooling run stably; the arch breaking component 4 using the air disc 401 and the pneumatic vibrator 402 can timely break the arch of the tungsten carbide powder in the barrel body 2 to achieve sustainable unloading; thereby, the tooling can realize the turnover of tungsten carbide powder on an automated production line.

[0038] The base 1 also has a receiving tray 103, which can be movably arranged between a first position and a second position. In the first position, the receiving tray 103 is located between the through hole 101 and the discharge port 202. In the second position, the receiving tray 103 staggers and avoids the communication between the through hole 101 and the discharge port 202. It can be understood that the setting of the receiving tray 103 can ensure that the tungsten carbide powder at the discharge port 202 and the pneumatic butterfly valve 3 will not pollute the production line. When the barrel body 1 is in the process of turnover, the receiving tray 103 is in the first position; when the barrel body 1 is unloading, the receiving tray 103 is in the second position.

[0039] Specifically, the receiving tray 103 is arranged on the base 1 through the moving pair 104 so that the receiving tray 103 can move between the first position and the second position. More specifically, a guide rail is arranged on both opposite sides of the through hole 101, and the receiving tray 103 is connected to a slider on the guide rail, and the slider is driven by a driving member such as a motor or a cylinder to slide on the guide rail, so that the receiving tray 103 can move between the first position and the second position.

[0040] In addition, a plurality of rolling elements 102 are spaced apart on the top edge of the base 1 and the rolling surface of each rolling element 102 faces the side of the base 1. The arrangement of the rolling elements 102 facilitates a more stable transmission of the base 1 during the turnover process.

[0041] Specifically, the rolling element 102 is a needle bearing. The base 1 is square in shape as a whole, and rolling elements 102 are arranged on four sides of the base 1, thereby improving the applicability of the entire tooling to the automatic production line.

[0042] Furthermore, in order to ensure the stability of the tooling turnover operation, a rubber pad 105 is provided at the bottom of the base 1, and the rubber pad 105 plays a buffering role.

[0043] As for the barrel body 2 , the barrel body 2 is in a cone-like barrel shape, which is helpful for the discharge of the powder in the barrel body 2 .

[0044] The feed port 201 is arranged at the top of the barrel 2, and a sealing cover is arranged on the feed port 201. This ensures that the tooling can smoothly receive materials from other equipment such as a mixing kettle, and then transfer the powder to the unloading equipment, etc. At the same time, during the transfer process, the powder will not pollute the environment.

[0045] Furthermore, a breathing valve 203 is provided on the barrel body 2, so that the breathing valve 203 can be used for filtering when exhausting air to ensure that the environment is not polluted.

[0046] As for the arch breaking component 4, the arch breaking component 4 has a plurality of air discs 401 and a plurality of pneumatic vibrators 402, wherein the plurality of pneumatic vibrators 402 are symmetrically arranged on the side wall of the barrel body 2, and the plurality of air discs 401 are circumferentially spaced and distributed on the side wall of the barrel body 2. The air discs 401 break the arch of the powder in the barrel body 2 by airflow, and the pneumatic vibrators 402 break the arch by vibrating the side wall of the barrel body 2, so that the arch can be broken according to the feeding of tungsten carbide powder of different grades. Among them, the pneumatic vibrators 402 are symmetrically arranged to ensure the balanced arch breaking of the barrel body 2. The specific number can be as shown in the figure, with two pneumatic vibrators 402 and three air discs 401, and the three air discs 401 can be set with a height difference to provide airflow to different positions.

[0047] As for the pneumatic butterfly valve 3 , its valve body is arranged at the discharge port 202 , and its pneumatic switch is arranged on the base 1 .

[0048] In addition, a circuit and gas circuit control docking box may be provided on the base 1 to facilitate connection and control of the tooling.
