Description

Technical Field

[0001] This application relates to the field of casting auxiliary technology, and in particular to a polishing device for metal castings. Background Technology

[0002] Casting can produce parts with complex shapes, especially blanks with complex internal cavities. It also has the advantages of wide adaptability and a wide range of raw material sources. Therefore, metal castings are widely used in industrial manufacturing. After metal castings are formed, they need to undergo cleaning, polishing, and other processes.

[0003] In related technologies, casting cleaning and casting polishing are two separate processes. Sometimes cleaning and polishing are adjacent in the process flow. Therefore, if some (hidden) areas are not cleaned properly during the cleaning process and molding sand remains, the polishing process will not only fail to achieve the desired polishing effect, but will also accelerate the wear rate of vulnerable parts (such as grinding needles, sandpaper sticks, etc.) on the polishing equipment, increasing the polishing cost.

Detailed Implementation

[0031] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0032] The polishing equipment for metal castings according to embodiments of this application is described below with reference to the accompanying drawings.

[0033] The metal casting polishing equipment of this application embodiment can be used in industrial production to clean and polish the external and internal surfaces of castings.

[0034] like Figure 1 and Figure 2 As shown, the metal casting polishing equipment of this application embodiment may include a polishing tank 100, a reflux tank group 200 and a jetting mechanism 300.

[0035] The polishing tank 100 has a movable pad net 110 at the bottom, and a jet nozzle 120 and a drain nozzle 130 on the side wall of the polishing tank 100. The jet nozzle 120 is connected to the jet mechanism 300, and the drain nozzle 130 is connected to the return pool group 200.

[0036] Specifically, when polishing metal castings, the relevant personnel first place the metal castings to be polished in the polishing tank 100, inject polishing fluid into the polishing tank 100 or the return tank group 200, and add magnetic polishing beads (magnetic polishing beads) into the polishing fluid.

[0037] Then, the relevant personnel control the jetting mechanism 300 to spray polishing fluid mixed with polishing beads into the polishing tank 100 through the jetting port 120. The metal casting is cleaned and polished by the scouring of the polishing fluid and the collision of the polishing beads. During the polishing process, the polishing fluid flows into the return tank group 200 through the drain port 130 for reuse.

[0038] It should be noted that, under the action of the jetting mechanism 300, the polishing fluid can be sprayed onto the metal casting, and at the same time, the polishing process can be turbulent in the polishing pool 100 to repeatedly scour the metal casting.

[0039] To clearly illustrate the previous embodiment, in one embodiment of this application, as follows: Figure 1 and Figure 2 As shown, a telescopic rod 111 is provided at the bottom of the polishing pool 100. One end of the telescopic rod 111 is connected to the polishing pool 100, and the other end of the telescopic rod 111 is connected to the movable pad net 110.

[0040] Specifically, during the polishing process of the metal casting in the polishing pool 100, the telescopic rod 111 can drive the movable pad 110 to move up and down, causing the metal casting to flip during the up and down movement, so as to polish the metal casting in multiple directions.

[0041] In one embodiment of this application, such as Figure 1 and Figure 2 As shown, the movable mat net 110 is divided into multiple pieces, and each piece of movable mat net 110 is connected to the other end of the telescopic rod 111.

[0042] Specifically, the multiple movable pads 110, when moving up and down in different ways, can better facilitate the flipping of metal castings. Especially during the simultaneous polishing of multiple metal castings, different parts of the metal castings can be subjected to the scouring of polishing fluids with varying intensities and concentrations, thereby improving the polishing effect and efficiency of the metal castings.

[0043] In one embodiment of this application, such as Figure 2 As shown, a detector 140 is provided on the side wall of the polishing pool 100, and the detector 140 is located on the side wall near the upper end.

[0044] Specifically, a detector 140 for detecting polishing fluid is installed at the upper part of the side wall of the polishing pool 100. During the polishing process of the metal casting, when the polishing fluid reaches the position of the detector 140, the controller can control the telescopic rod 111 to move downward according to the information obtained by the detector 140, or control the jetting mechanism 300 to reduce the jetting flow rate of the polishing fluid. This can prevent the polishing fluid from overflowing from the polishing pool 100 and improve the working stability of the metal casting polishing equipment.

[0045] The reflux tank assembly 200 includes a separation tank 210, a sedimentation tank 220, and a storage tank 230. The separation tank 210 is connected to a drain outlet 130 via a drain pipe 211. A magnetic rotor 212 is installed inside the separation tank 210, with its bottom located within the tank. A scraper 214 is positioned above the rotor 212, with one end abutting against the rotor and the other end connected to a flow pipe 215. The sedimentation tank 220 is connected to the separation tank 210, with its bottom lower than that of the separation tank 210. A connecting pipe 221 is located on the upper side of the sedimentation tank 220. The storage tank 230 is connected to the sedimentation tank 220 via the connecting pipe 221. A mixing tank 231 is installed within the storage tank 230, with one end of the flow pipe 215 extending into the mixing tank 231.

[0046] Specifically, during the polishing process of metal castings, impurities (such as molding sand, metal shavings, etc.) are removed from the castings and carried to the return pool group 200 by the polishing fluid. First, when the polishing fluid carrying impurities enters the separation pool 210 from the polishing pool 100 through the drain pipe 211, the magnetic rotating wheel 212 in the separation pool 210 attracts magnetic polishing beads from the polishing fluid onto the wheel. As the wheel rotates, the beads are carried away from the polishing fluid. During the rotation of the magnetic rotating wheel 212, the beads are moved to the scraper 214 above it. With the rotation of the wheel, the scraper 214 scrapes the beads off and causes them to fall into the flow pipe 215 under their own weight.

[0047] Then, the polishing fluid flows into the sedimentation tank 220, which is deeper and has a larger volume than the separation tank 210. After entering the sedimentation tank 220, the flow rate of the polishing fluid slows down (or stops). As the flow rate of the polishing fluid slows down, some impurities in the polishing fluid will settle to the bottom of the sedimentation tank 220, while the cleaner polishing fluid will flow into the storage tank 230 through the connecting pipe 221.

[0048] Finally, the clean polishing fluid flows into the mixing tank 231, and the magnetic polishing beads that fall into the flow tube 215 also fall into the mixing tank 231 along with the arrangement of the flow tube 215, so that the magnetic polishing beads and the polishing fluid are mixed together for use by the jetting mechanism 300.

[0049] It should be noted that the arrangement of the flow tube 215 is for reference. Figure 3 As shown, the end of the flow tube 215 that is close to the magnetic wheel 212 is positioned higher, while the end that is close to the mixing pool 231 is positioned lower, which is beneficial for the rolling of the magnetic polishing beads.

[0050] In one embodiment of this application, such as Figure 1 As shown, the mounting shaft of the magnetic wheel 212 passes through one side wall of the separation tank 210, and the mounting shaft extending out of the separation tank 210 is connected to the drive motor 213.

[0051] Specifically, the drive motor 213 can drive the magnetic wheel 212 to rotate, and can easily control the speed and direction of rotation of the magnetic wheel 212 to improve the separation effect between the polishing fluid and the magnetic polishing beads.

[0052] The jetting mechanism 300 may include a jetting pump 310, which is provided with a jetting input pipe 311 and a jetting output pipe 312. One end of the jetting input pipe 311 extends into the mixing tank 231, and one end of the jetting output pipe 312 is connected to the jetting port 120.

[0053] Specifically, during the polishing process of metal castings, the jet pump 310 draws polishing fluid containing magnetic polishing beads from the mixing tank 231 through the jet input pipe 311, pressurizes it, and then sprays it into the polishing tank 100 through the jet output pipe 312 and the jet outlet 120 to perform a rinsing and polishing operation on the metal castings in the polishing tank 100. When there is a certain amount of polishing fluid in the polishing tank 100, the jet pump 310 continuously sprays polishing fluid into the polishing tank 100, which can increase the flow velocity of the polishing fluid in the polishing tank 100 (i.e., form turbulence) and improve the polishing effect on the metal castings.

[0054] It should be noted that during the process of the jet pump 310 continuously injecting polishing fluid into the polishing tank 100, the polishing fluid also continuously flows through the drain port 130 into the return tank group 200, and the phenomenon of polishing fluid overflowing the polishing tank 100 will not occur.

[0055] To clearly illustrate the previous embodiment, in one embodiment of this application, the jet mechanism 300 further includes a jet pump 320, which is provided with a jet input pipe 321 and a jet output pipe 322. The jet input pipe 321 extends into the storage pool 230, and the jet output pipe 322 is connected to the polishing pool 100.

[0056] Specifically, during the polishing process of the metal castings in the polishing tank 100, the jet pump 320 obtains polishing fluid from the storage tank 230 or the mixing tank 231 through the jet input pipe 321, and jets it into the metal castings in the polishing tank 100 through the jet output pipe 322. The jet pump 320 can also be started and stopped by relevant personnel to continuously change the airflow direction of the polishing fluid within the polishing tank 100.

[0057] In one embodiment of this application, such as Figure 2 As shown, multiple jet nozzles 323 are provided on the jet output pipe 322, and the multiple jet nozzles 323 penetrate the side wall of the polishing tank 100 and extend into the polishing tank 100.

[0058] Specifically, using multiple jet nozzles 323 can improve the local cleaning and polishing effect on metal castings.

[0059] In one embodiment of this application, such as Figure 1 and Figure 3 As shown, the metal casting polishing equipment also includes an electromagnetic commutation component 400, which is disposed on the outside of the polishing pool 100.

[0060] Specifically, during the polishing process of metal castings using magnetic polishing beads, the electromagnetic commutation component 400 can be intermittently energized by personnel to intermittently generate a magnetic field in a certain direction within the polishing pool 100. Under the influence of this magnetic field, the magnetic polishing beads change direction, preventing them from simply moving with the flow direction of the polishing fluid. This allows for impact-type cleaning and polishing of the metal castings, increasing the uniformity of the polishing process.

[0061] In one embodiment of this application, the electromagnetic commutation assembly 400 may include multiple sets of electromagnetic coils 410 and a protective layer 420. The multiple sets of electromagnetic coils 410 are respectively arranged on the outside of the polishing pool 100, and the multiple sets of protective layers 420 wrap around the electromagnetic coils 410 at the positions that are not in contact with the polishing pool 100.

[0062] It should be noted that the electromagnetic coil 410 generates a magnetic field after being energized, and the magnetic field can be used to change the direction of movement of the magnetically conductive polishing beads.

[0063] The aforementioned protective layer 420 can be made of multi-layer magnetic shielding plates, which can prevent the generated magnetic field from affecting the gas electrical components or the surrounding area on the metal casting polishing equipment.

[0064] The metal casting polishing equipment of this application embodiment can use water as the polishing fluid and small-diameter steel balls as magnetic polishing beads. Water mixed with steel balls is injected into the polishing tank 100 from the return tank group 200 via the jet pump 310 in the jet mechanism 300, thereby rinsing and impacting the metal castings in the polishing tank 100, or increasing the flow speed of the water in the polishing tank 100 to scour the metal castings, thus achieving the effect of cleaning and polishing the metal castings.

[0065] During the cleaning and polishing of metal castings using a jet pump, water with different directions and flow rates can be injected into the polishing tank by the jet pump 320 to change the flow direction and speed of water and steel balls in the polishing tank 100.

[0066] In addition, during the cleaning and polishing of metal castings by the jetting mechanism 300, the magnetic field in the polishing pool 100 can be changed by the electromagnetic reversing component 400, causing the moving steel balls to change their direction of travel.

[0067] In summary, the metal casting polishing equipment described in this application can simultaneously perform cleaning and polishing operations on castings, thereby improving the polishing effect and reducing polishing costs.
