Description

TECHNICAL FIELD

[0001] The present application relates to the field of abrasive supply device, and particularly to a multi-stage adjustable water jet abrasive precise supply device. BACKGROUND

[0002] In water jet cutting processing, abrasive is often used to enhance the destructive power of the jet. Common abrasives include garnet, alumina, etc. The type, particle size and mass flow rate of the abrasive are important factors affecting the cutting quality. Therefore, in scientific research and actual processing, in order to achieve better cutting effect, it is necessary to frequently adjust the abrasive flow, abrasive type and abrasive particle size.

[0003] However, the existing abrasive supply device has a complex flow adjustment operation, and when different types and particle sizes of abrasives are needed, manual abrasive replacement operation is usually required, resulting in reduced processing efficiency. SUMMARY

[0004] In order to improve the problem that the existing abrasive supply device has a complex flow adjustment and abrasive replacement operation, the present application provides a multi-stage adjustable water jet abrasive precise supply device.

[0005] The multi-stage adjustable water jet abrasive precise supply device provided by the present application adopts the following technical solution:

[0006] A multi-stage adjustable water jet abrasive precise supply device comprises:

[0007] a tank body;

[0008] a support plate fixedly arranged in the tank body, the support plate separating the tank body into two regions, i.e., an abrasive storage region and an abrasive distribution region;

[0009] a plurality of partition plates fixedly arranged on the support plate, the plurality of partition plates separating the abrasive storage region into a plurality of independent storage chambers;

[0010] a plurality of flow channel pipes, the upper ends of the flow channel pipes penetrating through the support plate and being in communication with the corresponding storage chambers, and the lower ends of the flow channel pipes extending to the abrasive distribution region;

[0011] an opening and closing mechanism arranged on each flow channel pipe for controlling the opening or closing of the lower end of the corresponding flow channel pipe; when the lower end of the flow channel pipe is opened, the abrasive in the flow channel pipe flows out under the action of its own gravity.

[0012] In use, the abrasive is stored in the abrasive storage area, and the abrasive is filled into the flow channel pipe under the action of its own gravity. The opening and closing mechanism controls the opening or closing of the lower end of the corresponding flow channel pipe. When the lower end of the flow channel pipe is opened, the abrasive in the flow channel pipe flows out under the action of its own gravity, realizing the release of the abrasive. By controlling the number of opened flow channel pipes, the flow of the abrasive can be adjusted. When different particle sizes or different types of abrasive are needed, different particle sizes or different types of abrasive can be stored in different storage chambers, and then the corresponding flow channel pipes are controlled to open and close, so that different particle sizes or different types of abrasive can be released according to the needs of use. In this way, the problems of adjusting the flow and replacing the abrasive of the existing abrasive supply device can be improved.

[0013] Further, the flow channel pipe is provided with three different pipe diameters, namely a large pipe diameter flow channel pipe, a medium pipe diameter flow channel pipe and a small pipe diameter flow channel pipe, and each of the three pipe diameters is provided with a plurality of flow channel pipes.

[0014] Further, the abrasive flow in the large pipe diameter flow channel pipe is N times the abrasive flow in the medium pipe diameter flow channel pipe, and the number of the medium pipe diameter flow channel pipes is not less than N-1, wherein N is an integer not less than 10.

[0015] Further, the abrasive flow in the medium pipe diameter flow channel pipe is N times the abrasive flow in the small pipe diameter flow channel pipe, and the number of the small pipe diameter flow channel pipes is not less than N-1, wherein N is an integer not less than 10.

[0016] Since the opening and closing of each flow channel pipe can be independently controlled, by controlling the number of opened flow channel pipes, multi-stage precise adjustment of the abrasive flow can be realized. The larger the value of N is, the higher the adjustment precision is.

[0017] Further, the opening and closing mechanism comprises a material blocking plate rotatably arranged at the lower end of the flow channel pipe, and a driving assembly arranged on the flow channel pipe and used to drive the material blocking plate to flip and open or close the lower end of the flow channel pipe.

[0018] By driving the material blocking plate to flip through the driving assembly, the lower end of the flow channel pipe can be opened or closed.

[0019] Further, the flow channel pipe and the material blocking plate are made of ferromagnetic material, the driving assembly comprises a coil wound around the outer periphery of the flow channel pipe, and a magnetic shielding assembly is arranged between adjacent flow channel pipes.

[0020] The flow channel pipe and the coil constitute an electromagnet. When the coil is de-energized, the material blocking plate flips downward under the action of its own gravity, so that the lower end of the flow channel pipe is in an open state, and the abrasive can flow out of the lower end of the flow channel pipe. When the coil is energized, the material blocking plate flips upward under the action of the magnetic force, and the lower end of the flow channel pipe is shielded, preventing the abrasive from flowing out.

[0021] Further, the magnetic shielding assembly comprises a plurality of magnetic shielding plates made of magnetic shielding material, which are fixed to the support plate on one side of the abrasive distribution area, and the plurality of magnetic shielding plates separate the plurality of flow channel pipes from each other.

[0022] The magnetic shielding plates shield the magnetic field around each flow channel pipe, thereby reducing the magnetic field interference between adjacent flow channel pipes, so that after the coil is powered on, the flow channel pipe can only attract the material blocking plate connected thereto, thereby achieving independent control of the opening and closing of each flow channel pipe.

[0023] Further, the tank body is made of transparent material.

[0024] In this way, the operator can observe the use of the abrasive in the tank body to add the abrasive in time.

[0025] Further, the tank body is provided with a bottom cover at one end close to the abrasive distribution area, and the bottom cover is provided with a discharge hole.

[0026] The discharge hole is connected to the abrasive supply pipe of the water jet machine tool, and the abrasive flowing out of each flow channel pipe falls on the bottom cover and is supplied to the water jet machine tool through the discharge hole.

[0027] Further, one side of the bottom cover in the tank body is provided with a conical surface, and the discharge hole is located at the center of the conical surface.

[0028] In this way, the abrasive on the bottom cover can slide along the conical surface to the discharge hole.

[0029] In summary, the present application has at least one of the following beneficial technical effects:

[0030] 1. The electromagnet is composed of the flow channel pipe and the coil, and the independent control of the opening and closing of each flow channel pipe is realized by the overturning of the material blocking plate, and the flow of the abrasive can be accurately adjusted by setting a plurality of flow channel pipes with different diameters and controlling the number of opened flow channel pipes.

[0031] 2. The abrasive storage area is divided into a plurality of storage chambers by the partition plate, and when different particle sizes or different types of abrasives are needed, different particle sizes or different types of abrasives can be stored in different storage chambers, and then by controlling the opening and closing of the corresponding flow channel pipe, different particle sizes or different types of abrasives can be released according to the use requirement.

[0032] 3. The transparent tank body wall facilitates the operator to observe the use of the abrasive in the tank body to add the abrasive in time. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0038] The following will be described in detail with reference to the accompanying drawings Figures 1-4 The present application will be further described in detail.

[0039] The embodiment of the present application discloses a multi-stage adjustable water jet abrasive precise feeding device. Referring to Figure 1 and Figure 2 , the multi-stage adjustable water jet abrasive precise feeding device comprises a tank body 1 and a support plate 2 fixedly arranged in the tank body 1; in the embodiment, the tank body 1 is in a cylindrical shape, and the support plate 2 is in a circular shape. The support plate 2 is orthogonal to the axial direction of the tank body 1, and the support plate 2 divides the tank body 1 into two areas, i.e., an abrasive storage area 3 and an abrasive distribution area 4.

[0040] Referring to Figure 1 , one end of the tank body 1 close to the abrasive distribution area 4 is threadedly connected with a bottom cover 11, one side of the bottom cover 11 in the tank body 1 is arranged as a conical surface, a discharge hole 12 is formed in the center of the bottom cover 11, and the discharge hole 12 is in communication with an abrasive supply pipe of a water jet machine tool. One end of the tank body 1 relative to the bottom cover 11 is threadedly connected with a top cover 10.

[0041] Referring to Figure 2 and Figure 3 , a plurality of partition plates 5 are fixedly arranged on the support plate 2, and the partition plates 5 are orthogonal to the support plate 2. The plurality of partition plates 5 are all located in the abrasive storage area 3 and divide the abrasive storage area 3 into a plurality of independent storage chambers 6. A plurality of flow channel pipes 7 are connected to the support plate 2, the plurality of flow channel pipes 7 correspond to the positions of the plurality of storage chambers 6 one by one, the upper ends of the flow channel pipes 7 penetrate through the support plate 2 and are in communication with the corresponding storage chambers 6, and the lower ends of the flow channel pipes 7 extend to the abrasive distribution area 4.

[0042] Further, the flow channel pipe 7 is provided with an opening and closing mechanism for controlling the opening or closing of the lower end of the corresponding flow channel pipe 7; when the lower end of the flow channel pipe 7 is opened, the abrasive in the flow channel pipe 7 flows out under the action of its own gravity.

[0043] In use, the tank body 1 is vertically arranged, and the abrasive is stored in the abrasive storage area 3 and flows under the action of its own gravity and fills into the flow channel pipe 7. The opening or closing of the lower end of the corresponding flow channel pipe 7 is controlled by the opening and closing mechanism, and the opening of the lower end of the flow channel pipe 7 can release the abrasive from the flow channel pipe 7, which falls onto the bottom cover 11 and is supplied to the water jet machine tool through the discharge hole 12. The flow of the abrasive can be adjusted by controlling the number of opened flow channel pipes 7.

[0044] When different particle sizes or different types of abrasive are needed, different particle sizes or different types of abrasive can be stored in different storage chambers 6, and then the corresponding flow channel pipes 7 are opened and closed by the opening and closing mechanism, so that different particle sizes or different types of abrasive can be released according to the needs of use. In this way, it helps to improve the existing problems of abrasive supply device adjusting flow and replacing abrasive operation being more cumbersome.

[0045] In order to control the opening and closing of each flow channel pipe 7, with reference to Figure 3 , the opening and closing mechanism includes a rotating shaft 8 fixedly arranged at the lower end of the flow channel pipe 7 and a blocking plate 9 rotatably arranged on the rotating shaft 8, and the cross-sectional profile of the blocking plate 9 is larger than that of the corresponding flow channel pipe 7. The flow channel pipe 7 is provided with a driving assembly for driving the blocking plate 9 to flip and open or close the lower end of the flow channel pipe 7.

[0046] The flow channel pipe 7 and the blocking plate 9 are made of ferromagnetic material, which can be iron. The driving assembly includes a coil (not shown in the figure) wound around the outer periphery of the flow channel pipe 7, and the coil around the outer periphery of each flow channel pipe 7 is connected with the PLC controller.

[0047] Further, a magnetic shielding assembly is arranged between adjacent flow channel pipes 7, specifically, with reference to Figure 2 and Figure 3 , the magnetic shielding assembly includes a plurality of magnetic shielding plates 13 made of magnetic shielding material, which can be iron. The magnetic shielding plates 13 are fixedly connected to one side of the support plate 2 located in the abrasive distribution area 4, and the plurality of magnetic shielding plates 13 separate the plurality of flow channel pipes 7 from each other. The length of the magnetic shielding plate 13 in the axial direction of the flow channel pipe 7 is greater than the length of the flow channel pipe 7.

[0048] The flow channel pipe 7 and the coil constitute an electromagnet, when the coil is de-energized, the blocking plate 9 flips downward under the action of its own gravity, so that the lower end of the flow channel pipe 7 is in an open state, and the abrasive can flow out from the lower end of the flow channel pipe 7; when the coil is energized, the blocking plate 9 flips upward under the action of magnetic force, and the lower end of the flow channel pipe 7 is shielded, which hinders the flow of the abrasive.

[0049] The magnetic shielding plate 13 shields the magnetic field around each flow channel pipe 7, thereby reducing the magnetic field interference between adjacent flow channel pipes 7, so that the flow channel pipe 7 can only attract the material blocking plate 9 connected thereto after the coil is powered on, thereby realizing independent control of the opening and closing of each flow channel pipe 7.

[0050] By controlling the size of the current in the coil, the magnetic attraction force between the flow channel pipe 7 and the material blocking plate 9 can be adjusted. When the magnetic attraction force is sufficient to drive the material blocking plate 9 to flip upward and overcome the gravity of the abrasive in the flow channel pipe 7, the abrasive flow out of the flow channel pipe 7 is hindered.

[0051] Further, a limiting piece can be arranged at the lower end of the flow channel pipe 7. The limiting piece can be a limiting block (not shown in the figure) fixed to the lower end of the flow channel pipe 7 and located on the flipping track of the material blocking plate 9, for limiting the flipping angle of the material blocking plate 9 to be less than 90°. In this way, the material blocking plate 9 is facilitated to flip upward against its own gravity under the action of the magnetic force. Meanwhile, in order to avoid the flipping angle of the material blocking plate 9 being too small and thereby hindering the abrasive in the flow channel pipe 7 from flowing out, the flipping angle of the material blocking plate 9 can be preferably 70-80°.

[0052] Referring to Figure 3 and Figure 4 , the flow channel pipe 7 is provided with three different pipe diameters, i.e., a large-diameter flow channel pipe 71, a medium-diameter flow channel pipe 72 and a small-diameter flow channel pipe 73, and the three pipe diameters of the flow channel pipe are respectively provided with multiple flow channel pipes. Figure 3 Only the material blocking plate 9 on the large-diameter flow channel pipe 71 is shown in Figure 3 .

[0053] When the flow channel pipe 7 is in a vertical state, the abrasive flow in the flow channel pipe 7 is related to the pipe diameter of the flow channel pipe 7. Under the same other conditions, the larger the pipe diameter, the greater the abrasive flow in the flow channel pipe 7. Therefore, the abrasive flow in the flow channel pipe 7 can be changed by changing the pipe diameter.

[0054] In order to realize multi-stage precise adjustment of the abrasive flow, the abrasive flow in each large-diameter flow channel pipe 71 is N times that in each medium-diameter flow channel pipe 72, and the number of the medium-diameter flow channel pipe 72 is not less than N-1, wherein N is an integer not less than 10.

[0055] Similarly, the abrasive flow in each medium-diameter flow channel pipe 72 is N times that in each small-diameter flow channel pipe 73, and the number of the small-diameter flow channel pipe 73 is not less than N-1, wherein N is an integer not less than 10.

[0056] Since the opening and closing of each flow channel pipe 7 can be independently controlled, by controlling the number of the opened flow channel pipes 7, multi-stage precise adjustment of the abrasive flow can be realized, and the larger the value of N, the higher the adjustment precision.

[0057] For example, when N is 10, the abrasive flow in the large-diameter flow channel pipe 71 is 10 times that in the medium-diameter flow channel pipe 72, and the abrasive flow in the medium-diameter flow channel pipe 72 is 10 times that in the small-diameter flow channel pipe 73. Accordingly, the number of the medium-diameter flow channel pipes 72 is not less than 9, and the number of the small-diameter flow channel pipes 73 is not less than 9. Further, for example, the abrasive flow in the large-diameter flow channel pipe 71 is 100 g / min, and the abrasive flows in the medium-diameter flow channel pipe 72 and the small-diameter flow channel pipe 73 are 10 g / min and 1 g / min, respectively; thus, the flow regulation of the abrasive with a precision of 1 g / min can be achieved.

[0058] In this embodiment, in order to arrange the plurality of flow channel pipes 7 regularly, reference is made to Figure 4 The numbers of the large-diameter flow channel pipes 71, the medium-diameter flow channel pipes 72, and the small-diameter flow channel pipes 73 are 4, 16, and 12, respectively.

[0059] Further, reference is made to Figure 1 and Figure 4 The plurality of partition plates 5 are arranged in a longitudinal and transverse staggered manner, the large-diameter flow channel pipes 71 are located in the middle of the tank body 1, and the medium-diameter flow channel pipes 72 and the small-diameter flow channel pipes 73 are both located on the inner circumferential side of the tank body 1. The tank body 1 is made of transparent material, which can be transparent plastic, so that the operator can observe the abrasive usage inside the tank body 1, so as to add the abrasive in time.

[0060] The implementation principle of the multi-stage adjustable water jet abrasive precise feeding device according to the embodiment of the present application is as follows: during use, the abrasive is stored in the abrasive storage area 3, and the abrasive flows and fills into the flow channel pipe 7 under the action of its own gravity; the on-off of the corresponding flow channel pipe 7 is controlled by controlling the power-on or power-off of the coil, so as to drive the abrasive blocking plate 9 to flip and close or open the lower end of the corresponding flow channel pipe 7; when the lower end of the flow channel pipe 7 is opened, the abrasive can be released from the flow channel pipe 7; the flow of the abrasive can be regulated by controlling the number of the opened flow channel pipes 7.

[0061] When different particle sizes or different types of abrasives are needed, different particle sizes or different types of abrasives can be stored in different storage chambers 6, and then the different particle sizes or different types of abrasives can be released according to the use requirements by controlling the opening and closing of the corresponding flow channel pipes 7; thus, the problem that the existing abrasive feeding device is difficult to regulate the flow and the operation of replacing the abrasive is relatively cumbersome can be improved.

[0062] The above are the preferred embodiments of the present application, which do not limit the protection scope of the present application, so that: any equivalent changes made according to the structure, shape, principle of the present application shall be covered within the protection scope of the present application.
