Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to a large-size foam body grinding device. Background Art

[0002] At present, large-size foam bodies are widely used. On ships and docks, the common large-size foam bodies are usually cylindrical with arc-shaped edges. The diameter is generally more than 1 meter, and some reach a diameter of more than 2 meters. The outermost layer of some large-size foam bodies needs to be sprayed with a protective layer. In order to achieve the required spraying effect, the outer surface of the large-size foam body needs to be polished after it is formed, and then sprayed after polishing.

[0003] For the circumferential surface, if the method of mechanical grinding is adopted, the common method is to adopt a grinding wheel, so that the grinding wheel and the large-sized foam body are in relative motion. However, because the foam body diameter is large and the foam body weight is heavy (generally more than 200kg, and some exceed 500kg), if the diameter of the grinding wheel is small, because the surface of the foam body is uneven, it is very easy to get the grinding wheel stuck during the relative motion of the two circumferences, causing the power device of the grinding wheel to shut down or malfunction. In addition, if the diameter of the grinding wheel is small, very strong power is required, and the power device cost is high. If the power device is stuck during the grinding process, it will cause malfunction, and the maintenance or replacement cost is very high. In order to achieve an efficient and economical grinding effect, this requires that the diameter of the grinding wheel needs to exceed the diameter of the large-sized foam body to achieve efficient grinding efficiency, and the grinding wheel is equipped with strong power. However, the grinding equipment with a large-diameter grinding wheel is very large in size, the equipment cost is also very high, and it is inconvenient to operate. Therefore, in the foam industry, the current polishing method relies on manual polishing. This method has several challenges: the inability to accurately control the circumference and edge arc dimensions, resulting in the inability to achieve the desired circular shape or arc; low polishing efficiency; and high dust production and a poor working environment, with dust harming the health of the polishers. Therefore, research on improving the efficiency of foam polishing, simplifying the foam polishing equipment structure, and reducing the cost of foam polishing is a pressing issue.

[0004] A device for preparing a water-floating solid-core polyurea elastomer is disclosed in patent CN107234521B. The device moves the processed body along the slide rails left and right, fixes the processed body at both ends, adjusts the position of the cutter, then starts the second frequency conversion motor to complete the cutting or grinding process until the desired product shape is obtained. The device can improve the grinding efficiency of the foam body. However, on the one hand, the processed object in the patent is essentially a polyurea elastomer, which is a local surface processing method after the foam body is sprayed with polyurea. The device processes the entire processed body by first fixing it and then cutting or grinding it. The entire processed body cannot rotate, so the device can only partially process the polyurea elastomer and cannot achieve rapid grinding of the entire outer surface of the foam body. On the other hand, the device cannot quickly grind the edge of the foam body to a circular arc size, and cannot effectively prevent dust from affecting the operator.

[0005] A fender arc surface grinder is disclosed in patent CN219853740U. The device is provided with two grinding wheels, which can speed up the grinding speed and greatly improve the work efficiency. The device is provided with a cleaning device, which can simultaneously grind and clean without the need for additional equipment and manpower, improving work efficiency and product quality, and reducing dust generated during grinding. However, the two grinding wheels of the grinder are arranged side by side on the top of the grinder, and the platform is a conveyor belt that cannot rotate the fender. The device cannot achieve rapid grinding of the edge of the fender and the circular surface of the fender. The device has a water spraying device for dust removal. If the water spraying function is enabled during grinding, the water remaining on the surface of the fender after grinding can cause quality problems such as bulging or pinholes during the subsequent polyurea spraying process.

[0053] Step three, foam body surface polishing: start the polishing power head 32 in sequence, shake the first rocker 34, adjust the polishing power head 32 to the required position, polish the surface of the foam body contacted by the milling cutter and / or grinding wheel piece to be smooth through the action of the milling cutter and / or grinding wheel piece, then start the guide rail 31 to enable the polishing power head 32 to move along the length direction of the foam body, polish the surface of the foam body to be smooth, and shake the first rocker 34 to adjust the polishing power head 32 to move away from the foam body; complete the polishing of the surface of the foam body;

[0054] Step 4: Grinding the edges of the foam body: Start the angle motor 401, and under the action of the second rocker 403 and the third rocker 404, adjust the customized R-angle sand, i.e., the curved grinding wheel, to the position where the edges of the foam body are to be polished; grind the edges of the left and right ends of the foam body to the required arc size; and complete the grinding of the edges of the foam body;

[0055] Step 5: Stop the machine and remove the polished foam body from the supporting device 2 to obtain the polished foam body.

[0056] Currently in the foam industry, large-sized foam surfaces are polished manually, which not only results in poor polishing effects, low polishing efficiency, and high labor costs, but also in a poor polishing environment, and dust is harmful to the health of the polishers. The present application adopts a turning and milling processing method similar to that of a lathe. First, a large-sized foam body is mounted on a support device 2, which is rotated under the action of a power device 5. The milling cutter and the grinding wheel are respectively mounted on a polishing power head 32, and the polishing power head 32 is controlled to approach different positions on the foam surface. The foam surface is first turned and milled, and then polished smooth. The polishing equipment is equipped with a synchronous dust collection device, which can clean up the dust in time and improve the polishing environment; an automatic control device is equipped to realize automatic polishing, improve the polishing effect and polishing efficiency, reduce labor costs, and solve the problem of dust damaging the health of polishers during manual polishing. In addition, through the process, the setting of the process steps can be simplified, the convenience of operation can be improved, the foam processing time can be shortened, and efficient and economical polishing can be achieved.

[0057] Furthermore, the motion trajectory of the grinding device 3 is perpendicular to the rotational trajectory of the foam body. The grinding equipment utilizes a milling method to grind the foam body. This method utilizes a milling cutter and a grinding wheel. The distance between the milling cutter and grinding wheel and the central axis of the foam body is adjustable. The milling cutter and grinding wheel can be moved along the length of the foam body. The distance between the R-angle grinding wheel (i.e., the curved grinding wheel) and the central axis of the foam body can be adjusted. The distance between the R-angle grinding wheel and the central axis of the foam body is adjustable. The entire grinding process is automatically controlled. Grinding dust can be promptly collected and cleaned.

[0058] Different from the prior art which usually adopts the method of grinding to process the surface of the foam body, which is prone to getting stuck, the present application adopts a grinding device 3 whose motion trajectory is perpendicular to the rotational motion trajectory of the foam body, which can effectively improve the stability and safety of the foam body grinding, and can also reduce the damage caused to the foam body by the grinding equipment during the grinding process, which is beneficial to extend the service life of the grinding equipment, and is also beneficial to improve the grinding efficiency and ensure the grinding effect.

[0059] In the present utility model, any foam body grinding equipment can include a large-size foam body grinding equipment structure described in this embodiment, and based on the relevant structures and assembly relationships of the grinding device 3 and the angle forming device 4 provided in this embodiment, the foam body grinding equipment also includes conventional components including cutting tools, support seats, and frames 1. Since they are all existing technologies, they will not be described in detail here.

[0060] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
