Description

Technical Field

[0001] This utility model relates to the field of mechanical device technology, and in particular to an abrasive flow polishing device for spinneret molds. Background Technology

[0002] Abrasive fluid polishing machines are fluid grinding devices that use viscoelastic polymers as a carrier and elastic, hard, flowing abrasive particles as the processing medium. Under pressure, the abrasive particles flow over the surface to achieve the desired processing. Abrasive fluid machining improves surface quality by removing micro-protrusions on the workpiece surface through abrasive particles, and it belongs to ultra-precision machining. When the workpiece to be polished is relatively large, problems such as insufficient abrasive, short polishing time, and uneven polishing may occur. Because the spinneret mold is relatively large, these problems also exist, resulting in unsatisfactory polishing effects. Utility Model Content

[0003] The main technical problem solved by this utility model is to provide a special abrasive flow polishing equipment for spinneret molds, which solves the problems of insufficient abrasive, short polishing time and uneven polishing when polishing large workpieces with existing abrasive flow equipment.

[0004] To solve the above-mentioned technical problems, the present invention provides a special abrasive flow polishing device for spinneret molds, comprising a main frame and a lower abrasive cylinder, an oil cylinder, a lower funnel, an abrasive pipe, a diversion pipe, equidistant pipes, and an upper funnel disposed on the main frame. The oil cylinder is located directly above the lower funnel. The bottom of the lower funnel is connected to one end of the abrasive pipe, and the other end of the abrasive pipe is connected to one end of the diversion pipe. The other end of the diversion pipe is simultaneously connected to multiple equidistant pipes. The upper end of each equidistant pipe forms an enlarged trumpet-shaped diversion groove, and all the trumpet-shaped diversion grooves are located directly below the spinneret mold. The upper funnel is located above the lower funnel, and the abrasive collected in the upper funnel can fall into the lower funnel.

[0005] The abrasive pipeline is equipped with a shut-off valve for flow restriction.

[0006] Furthermore, the upper and lower parts of the hydraulic cylinder are equipped with hydraulic cylinder limit switches for limiting the hydraulic cylinder stroke.

[0007] Furthermore, the polishing equipment also includes a PLC control system, which comprises controllers, touch screens, relays, cables, and transformers that are interconnected.

[0008] Furthermore, the polishing equipment has a frame around its outer periphery.

[0009] Furthermore, the frame is an aluminum profile frame, a welded frame, or a stainless steel frame.

[0010] Furthermore, the end of the push rod of the cylinder is provided with an umbrella-shaped piston.

[0011] The beneficial effects of this utility model are:

[0012] This utility model is a special abrasive flow polishing device designed for special workpieces (spinneret molds). It is mainly designed to solve the problem of uneven polishing of large workpieces. It contains multiple equally spaced pipes. The flared flow channels at the ends of the equally spaced pipes allow the abrasive to flow out evenly and into the holes of the spinneret mold to polish the product. After polishing, during the abrasive backflow period, the shut-off valve is activated to prevent the abrasive in the pipes from flowing back. When the abrasive cylinder squeezes the abrasive for further polishing, the abrasive will polish the product more evenly and persistently. This solves the problems of insufficient abrasive, short polishing time, and uneven polishing that occur when polishing large workpieces with existing abrasive flow equipment.

[0020] Example: A special abrasive flow polishing device for spinneret molds, such as... Figure 1 and Figure 2 As shown, the assembly includes a main frame 2 and a lower abrasive cylinder 3, a hydraulic cylinder 15, a lower funnel 5, an abrasive pipe 8, a diversion pipe 10, equidistant pipes 11, and an upper funnel 7, all mounted on the main frame. The hydraulic cylinder is located directly above the lower funnel. The bottom of the lower funnel is connected to one end of the abrasive pipe, and the other end of the abrasive pipe is connected to one end of the diversion pipe. The other end of the diversion pipe is simultaneously connected to multiple equidistant pipes. The upper end of each equidistant pipe forms an enlarged flared-mouth diversion groove 12, and all the flared-mouth diversion grooves are located directly below the spinneret mold 13. The upper funnel is located above the lower funnel, and the abrasive collected in the upper funnel can fall into the lower funnel.

[0021] The abrasive pipeline is equipped with a shut-off valve 9 for flow restriction.

[0022] In this embodiment, the upper and lower cylinders are equipped with cylinder limit switches 6 for limiting the cylinder stroke.

[0023] In this embodiment, the polishing equipment also includes a PLC control system 14, which includes controllers, touch screens, relays, cables, and transformers that are interconnected.

[0024] In this embodiment, the polishing equipment is covered by a frame (or housing) 1.

[0025] In this embodiment, the frame is an aluminum profile frame, a welded frame, or a stainless steel frame.

[0026] In this embodiment, the end of the push rod of the hydraulic cylinder is provided with an umbrella-shaped piston 16.

[0027] Frame 1 covers the outer perimeter of the equipment to protect its internal structure.

[0028] The main frame 2 is used to install the main structure of the equipment and to fix the lower grinding cylinder, oil cylinder, etc.

[0029] The lower abrasive cylinder 3 is fixed on the main frame and is used to store abrasive.

[0030] Abrasive 4, when extruded, can flow on the surface or inside the product, removing burrs and improving surface finish.

[0031] The lower funnel 5 is used to recover abrasive. The abrasive slides from the upper funnel to the lower funnel and is then recovered to the lower abrasive cylinder through the lower funnel.

[0032] The cylinder limit switch 6 is installed on the upper and lower sides of the cylinder to sense the reciprocating motion of the cylinder.

[0033] The upper funnel 7 is used to recover abrasive materials, which slide through the product and grid plate into the upper funnel.

[0035] After the abrasive extrusion process is completed, the shut-off valve 9 opens to prevent abrasive backflow in the abrasive pipeline.

[0036] Diversion pipe 10: After the abrasive flows out of the abrasive pipe 8, it is distributed to each equidistant pipe 11 through the diversion pipe.

[0037] Equidistant pipe 11: The diversion pipe 10 distributes the abrasive into the equidistant pipe, making the abrasive evenly distributed and resulting in better polishing effect.

[0038] 12. The abrasive fills the 12.2-inch funnel at the end of the equidistant pipe and is evenly distributed into the holes of the spinneret mold. The funnel increases the contact area between the end of the equidistant pipe and the bottom of the spinneret mold, facilitating the full entry of the abrasive into the holes of the spinneret mold.

[0039] Spinneret mold 13: Large spinneret mold.

[0040] PLC Control System 14: Includes PLC programmable controller, touch screen, relays, cables, transformers, etc.

[0041] The working principle and process of this utility model:

[0042] The hydraulic cylinder pushes the piston down, squeezing the abrasive in the lower funnel. The abrasive passes through the lower abrasive cylinder, abrasive pipe, diversion pipe and equidistant pipe in sequence and enters the hole of the spinneret mold to grind and polish the hole. The abrasive is then collected in the upper funnel and flows back to the lower funnel. The above process is repeated to grind the hole repeatedly.

[0043] For particularly large workpieces, multiple sets of the above structure can be set up to ensure that each feed hole of the spinneret mold can be ground evenly.

[0044] The above description is merely an embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structure made using the contents of the present utility model specification and drawings, or directly or indirectly applied to other related technical fields, are similarly included within the patent protection scope of the present utility model.
