Description

Technical Field

[0001] This invention relates to the field of precision casting technology, and in particular to a welding knife cleaning device. Background Technology

[0002] Lost-wax casting, also known as wax pattern casting, is widely used in the precision casting industry due to its convenience for mass production and consistent precision. It is a key method for forming precision casting products. Wax pattern assembly involves welding together the product wax pattern and the sprue mold head.

[0003] During the wax model assembly process, a welding knife is used to partially melt and weld the product wax model and the sprue mold head together. Waste wax remains on the welding knife, and the melted waste wax may flow to the welding joint. The presence of waste wax absorbs additional heat, causing uneven heat conduction and preventing proper fusion of the wax at the weld, leading to incomplete welds and affecting the quality of the wax model assembly, potentially resulting in casting failure. To address this, current wax model assembly processes typically involve operators manually wiping away the residual waste wax from the welding knife to keep it clean and improve welding quality. However, the heating temperature of the wax is usually above 200 degrees Celsius, posing a safety hazard as operators are prone to burns when manually wiping away the residual waste wax. Summary of the Invention

[0004] Based on the above analysis, the present invention aims to provide a welding knife cleaning device to solve the problem in the prior art that requires operators to manually wipe off the residual waste wax on the welding knife, which is prone to burns and poses a safety hazard.

[0005] The objective of this invention is mainly achieved through the following technical solutions:

[0006] A welding knife cleaning device includes a housing and a cleaning unit. The housing has a working chamber, and the cleaning unit is installed inside the working chamber. The cleaning unit includes an air blowing device for blowing out gas to remove residual waste wax from the welding knife.

[0007] Furthermore, the cleaning unit also includes a heating device installed inside the working chamber and connected to an external air source. The heating device is used to heat the compressed gas input from the external air source.

[0008] Furthermore, the air blowing device is connected to the heating device.

[0009] Furthermore, the heating device includes a heating device body and a heating mechanism. The heating device body is connected to an external gas source and can input compressed gas. The heating mechanism is installed inside the heating device body and is used to heat the compressed gas.

[0010] Furthermore, the heating device body has a first air chamber, which is connected to an external air source and is used to buffer the compressed gas input from the external air source.

[0011] Furthermore, the air blowing device includes an air blowing device body and an air nozzle, the air blowing device body being connected to the first air chamber; the air nozzle being mounted on the air blowing device body and used to guide compressed gas to be blown toward the welding knife.

[0012] Furthermore, the air blowing device body has a connecting air port and a second air chamber, and the connecting air port is connected to the second air chamber.

[0013] Furthermore, the heating device body is provided with a connecting air passage, and the second air chamber is connected to the first air chamber through the connecting air passage.

The cleaning unit is installed in the working chamber of the housing and is used to quickly clean the welding knife. The cleaning unit includes a heating device and a blowing device. The heating device is connected to an external air source and is used to buffer and heat the compressed gas input from the external air source so that the compressed gas reaches the dewaxing temperature. The blowing device is connected to the heating device and is used to blow out high-temperature compressed gas to remove residual waste wax on the welding knife, thereby quickly cleaning the welding knife and keeping it clean.

[0036] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0037] Example 1

[0038] One specific embodiment of the present invention discloses a welding knife cleaning device, such as... Figure 1 As shown, the device includes a housing 1 and a cleaning unit 2. The housing 1 has a working chamber with an opening at the top, allowing easy insertion of a welding knife into the working chamber. The cleaning unit 2 is installed inside the working chamber of the housing 1 and faces the opening. When the welding knife is inserted into the working chamber through the opening, the cleaning unit 2 quickly cleans the welding knife. Compared with the prior art, by quickly cleaning the welding knife within the working chamber of the housing 1 using the cleaning unit 2, there is no need for operators to manually wipe off residual waste wax from the welding knife, and waste wax splashing can also be avoided. This not only improves the safety of welding knife cleaning but also increases the cleaning efficiency.

[0039] Preferably, such as Figure 2As shown, the cleaning unit 2 includes a heating device 21 and an air blowing device 22. The heating device 21 is fixedly connected to the housing 1 and connected to an external air source. The heating device 21 is used to buffer and heat the compressed gas input from the external air source so that the compressed gas reaches the dewaxing temperature. The air blowing device 22 is connected to the heating device 21. The air blowing device 22 is used to blow out high-temperature compressed gas to remove the residual waste wax on the welding knife, quickly clean the welding knife, keep the welding knife clean, avoid the operator manually wiping the welding knife, improve the safety of cleaning the welding knife, avoid burns to the operator, and eliminate safety hazards.

[0040] Preferably, such as Figure 3 As shown, the heating device 21 includes a heating device body 211 and a heating mechanism 212. The heating device body 211 is fixedly installed on the housing 1. The heating device body 211 has a first air chamber 2111, which is connected to an external air source and is used to buffer the compressed gas input from the external air source. The heating mechanism 212 is disposed in the first air chamber 2111 and is used to heat the compressed gas buffered in the first air chamber 2111 to make the compressed gas reach the temperature required for dewaxing. Because the first air chamber 2111 has a buffering function, the heating mechanism 212 can fully heat the compressed gas, making the compressed gas heated evenly and improving the heating efficiency. This allows the blown high-temperature compressed gas to quickly melt the waste wax remaining on the welding knife, thereby improving the efficiency and quality of cleaning the welding knife.

[0041] Preferably, the heating device body 211 is provided with a connecting air passage 2112, which is connected to the air blowing device 22 and is used to deliver the heated compressed gas in the first air chamber 2111 to the air blowing device 22 to remove the waste wax remaining on the welding knife.

[0042] Preferably, the aperture of the connecting air passage 2112 is smaller than the aperture at the connection between the first air chamber 2111 and the external air source. This ensures that the compressed gas from the external air source into the first air chamber 2111 is not directly delivered to the blowing device 22, but instead fills the first air chamber 2111 for buffering. This allows the heating mechanism 212 to fully heat the compressed gas, ensuring uniform heating. Consequently, the blown-out high-temperature compressed gas can quickly melt the residual waste wax on the welding knife, thereby improving the efficiency and quality of cleaning the welding knife.

[0043] Preferably, such as Figure 4 and Figure 5As shown, the air blowing device 22 includes an air blowing device body 221 and an air nozzle 222. The air blowing device body 221 is fixedly installed on the heating device body 211. The air blowing device body 221 has a connecting air port 2211 and a second air chamber 2212. The second air chamber 2212 is connected to the first air chamber 2111 through a connecting air passage 2112, so that the compressed gas heated in the first air chamber 2111 is input into the second air chamber 2212. The connecting air port 2211 is connected to the second air chamber 2212. The air nozzle 222 is installed on the air blowing device body 221 and is arranged opposite to the connecting air port 2211. It is connected to the second air chamber 2212 through the connecting air port 2211. The air nozzle 222 is used to guide the high-temperature compressed gas in the second air chamber 2212 to blow towards the welding knife to melt and remove the residual waste wax on the welding knife, so as to keep the welding knife clean.

[0044] Preferably, multiple air nozzles 222 are provided; multiple connecting air ports 2211 are provided, and the number of connecting air ports 2211 is equal to the number of air nozzles 222; multiple connecting air ports 2211 are arranged one-to-one with multiple air nozzles 222; multiple air nozzles 222 are evenly arranged circumferentially on the air blowing device body 221, so that high-temperature compressed gas can be blown out to the welding knife from multiple directions, further accelerating the melting speed of the residual waste wax on the welding knife, and removing the melted waste wax on the welding knife from multiple directions, so as to remove the residual waste wax in the dead corners of the welding knife, and further improving the cleaning efficiency and cleaning quality of the welding knife.

[0045] Preferably, multiple connecting air channels 2112 are provided, and the multiple connecting air channels 2112 are evenly arranged around the circumference, so that the high-temperature compressed gas buffered in the first air chamber 2111 can be quickly filled into the second air chamber 2212, and the second air chamber 2212 can be quickly filled. This allows the multiple air nozzles 222 to blow out high-temperature compressed gas synchronously, and ensures that the high-temperature compressed gas blown towards the welding knife from multiple directions has the same temperature. This avoids the phenomenon that the melted waste wax solidifies at low temperatures on the welding knife due to uneven temperature, and further improves the cleaning quality of the welding knife.

[0046] Preferably, the heating device body 211 is annular; the first air chamber 2111 is an annular cavity.

[0047] Preferably, the heating mechanism 212 is an electrothermal resistance wire in the prior art.

[0048] Example 2

[0049] Example 2 is a further improvement based on Example 1, such as... Figure 4As shown, the air blowing device 22 also includes a pulse mechanism 223, which is disposed inside the air blowing device body 221. The pulse mechanism 223 is used to control the air nozzle 222 to blow out pulsed high-temperature compressed gas, thereby realizing pulsed air blowing on the welding knife, further improving the efficiency of removing molten waste wax on the welding knife, and further improving the cleaning quality of the welding knife.

[0050] Preferably, the air blowing device body 221 has a polygonal ring structure, the second air chamber 2212 is an annular air chamber, the pulse mechanism 223 is disposed in the second air chamber 2212 and can rotate circumferentially along the axis of the air blowing device body 221 within the second air chamber 2212. By rotating the pulse mechanism 223 within the second air chamber 2212, the opening and closing of the connecting air port 2211 can be controlled, thereby controlling the alternating connection and disconnection between the air nozzle 222 and the second air chamber 2212, so as to realize the blowing out of pulsed high-temperature compressed gas from the air nozzle 222, thereby improving the efficiency and cleaning quality of removing molten waste wax from the welding knife.

[0051] Preferably, such as Figure 6 As shown, the pulse mechanism 223 includes a pulse body 2231 and blades 2232. The pulse body 2231 has an annular structure. The pulse body 2231 is disposed within the second air chamber 2212 and can rotate circumferentially within the second air chamber 2212 along the axis of the blowing device body 221. The pulse body 2231 is provided with an air window 2233, which can intermittently communicate with the connecting air port 2211. The blades 2232 are disposed on the pulse body 2231 and are opposite to the connecting air passage 2112. After heating in the first air chamber 2111... Compressed gas is introduced into the second air chamber 2212 through the connecting air passage 2112. Since the blade 2232 is opposite to the connecting air passage 2112, the compressed gas acts on the blade 2232. After the blade 2232 is subjected to force, it drives the pulse body 2231 to rotate. The rotation of the pulse body 2231 realizes the intermittent connection between the control air window 2233 and the connecting air port 2211, thereby realizing the alternating connection and disconnection between the control air nozzle 222 and the second air chamber 2212, realizing the pulsed high-temperature compressed gas blown out from the air nozzle 222, improving the efficiency and cleaning quality of removing molten waste wax from the welding knife.

[0052] Example 3

[0053] Example 3 is a further improvement based on Example 1 or Example 2. The air nozzle 222 is rotatably connected to the air blowing device body 221, so that the air nozzle 222 can swing up and down, thereby allowing the high-temperature compressed gas blown out by the air nozzle 222 to swing along the vertical direction of the welding knife to clean the entire welding knife. The entire welding knife can be cleaned without manually moving the welding knife in the vertical direction, thereby further improving the cleaning efficiency and cleaning quality of the welding knife.

[0054] Preferably, such as Figure 7 As shown, the air nozzle 222 includes a ring seat 2221 and a blow nozzle 2222. The ring seat 2221 is sleeved on the air blowing device body 221 and can reciprocate on the air blowing device body 221, i.e., swing. The blow nozzle 2222 is disposed on the ring seat 2221 and can swing with the swing of the ring seat 2221, so that the high-temperature compressed gas blown out by the blow nozzle 2222 can swing along the vertical direction of the welding knife to clean the entire welding knife, thereby achieving overall cleaning of the welding knife and improving the cleaning efficiency and cleaning quality of the welding knife.

[0055] Preferably, the ring seat 2221 is provided with a third air chamber 2223, and the mouthpiece 2222 is connected to the third air chamber 2223; the third air chamber 2223 is also connected to the connecting air port 2211, so that the mouthpiece 2222 is connected to the second air chamber 2212.

[0056] Preferably, the third air chamber 2223 is an annular cavity, so that when the ring seat 2221 swings, the nozzle 2222 can always remain connected with the second air chamber 2212, thereby realizing continuous blowing of the welding knife as a whole through the nozzle 2222, improving the cleaning efficiency and cleaning quality of the welding knife.

[0057] Preferably, the air blowing device 22 further includes a transmission mechanism 224. The air nozzle 222 is connected to the pulse body 2231 in the pulse mechanism 223 through the transmission mechanism 224, so that the pulse body 2231 rotates circumferentially along the axis of the air blowing device body 221 while driving the air nozzle 222 to swing synchronously. This enables the air nozzle 222 to blow out pulsed high-temperature compressed gas while the blown pulsed high-temperature compressed gas can swing along the vertical direction of the welding knife to perform pulsed cleaning of the entire welding knife, thereby further improving the cleaning efficiency and cleaning quality of the welding knife.

[0058] Preferably, the pulse body 2231 is further provided with a first ring tooth (not shown in the figure).

[0059] Preferably, such as Figure 8As shown, the transmission mechanism 224 includes a first transmission gear 2241, a second transmission gear 2242, a third transmission gear 2243, and a transmission ring 2245. The first transmission gear 2241 is connected to the first ring tooth on the pulse body 2231, and when the pulse body 2231 rotates, it can synchronously drive the first transmission gear 2241 to rotate. The second transmission gear 2242 is fixedly connected to the first transmission gear 2241 through a rotating shaft, so that it can rotate synchronously with the first transmission gear 2241. The third transmission gear 2243 is installed on the air blowing device body 221 and is rotatably connected to the air blowing device body 221. The third transmission gear 2243 is intermittently connected to the second transmission gear 2242, thereby realizing the reciprocating rotation of the third transmission gear 2243. The transmission ring 2245 is installed on the pulse body 2231. Mounted on the air blowing device body 221, and capable of rotating circumferentially along the axis of the air blowing device body 221; the transmission ring 2245 is connected to the third transmission gear 2243, which drives the transmission ring 2245 to reciprocate along the axis of the air blowing device body 221; the transmission ring 2245 is also connected to the air nozzle 222, which drives the air nozzle 222 to swing between 0° and 90° in the vertical direction, thereby enabling the air nozzle 222 to blow out pulsed high-temperature compressed gas while the blown pulsed high-temperature compressed gas can swing along the vertical direction of the welding knife to perform pulsed cleaning of the entire welding knife, thereby further improving the cleaning efficiency and cleaning quality of the welding knife.

[0060] Preferably, such as Figure 9As shown, the transmission mechanism 224 further includes a reset spring 2244, one end of which is fixedly connected to the air blowing device body 221, and the other end is fixedly connected to the third transmission gear 2243. The second transmission gear 2242 is a semi-circular transmission gear, thereby intermittently connecting the third transmission gear 2243 with the second transmission gear 2242, realizing intermittent driving of the third transmission gear 2243 to rotate. When the third transmission gear 2243 is connected to the second transmission gear 2242, it can drive the third transmission gear 2243 to rotate, thereby driving the transmission ring 2245 to rotate, and simultaneously compressing the reset spring 2244. When 2242 is disengaged, the third transmission gear 2243 rotates in the opposite direction under the elastic thrust of the reset spring 2244, thereby driving the transmission ring 2245 to rotate in the opposite direction. The reset spring 2244 synchronously returns to its initial state, thereby driving the transmission ring 2245 to reciprocate along the axis of the air blowing device body 221, thereby driving the air nozzle 222 to swing between 0° and 90° in the vertical direction. This allows the air nozzle 222 to blow out pulsed high-temperature compressed gas while simultaneously allowing the pulsed high-temperature compressed gas to swing along the vertical direction of the welding knife to perform pulsed cleaning of the entire welding knife, thereby further improving the cleaning efficiency and cleaning quality of the welding knife.

[0061] Preferably, the reset spring 2244 is a planar spiral spring.

[0062] Preferably, the air blowing device body 221 is further provided with a slide 2213.

[0063] Preferably, the ring seat 2221 is further provided with a slide 2224, which is a spiral slide.

[0064] Preferably, such as Figure 10 As shown, the transmission ring 2245 is provided with a second ring tooth 22451, a driving protrusion 22452, and a sliding groove 22453. The second ring tooth 22451 is connected to the third transmission tooth 2243, thereby realizing the reciprocating circumferential rotation of the transmission ring 2245 through the third transmission tooth 2243. The slide block 2213 is inserted into the sliding groove 22453 and can slide within the sliding groove 22453, thereby supporting the reciprocating rotation of the transmission ring 2245 along the axis of the air blowing device body 221. The driving protrusion 22452 is inserted into the slide rail 2224 and can slide within the slide rail 2224, thereby realizing the transmission ring 2245 driving the air nozzle 222 to swing between 0° and 90° in the vertical direction. This allows the air nozzle 222 to blow out pulsed high-temperature compressed gas while simultaneously allowing the pulsed high-temperature compressed gas to swing along the vertical direction of the welding knife to perform pulsed cleaning of the entire welding knife, thereby further improving the cleaning efficiency and cleaning quality of the welding knife.

[0065] Preferably, multiple driving protrusions 22452 are provided, and the number of driving protrusions 22452 is equal to the number of air nozzles 222. The multiple driving protrusions 22452 and the multiple air nozzles 222 are arranged one-to-one, so that when the driving transmission ring 2245 reciprocates along the axis of the air blowing device body 221, it simultaneously drives the multiple air nozzles 222 to swing between 0° and 90° in the vertical direction. This allows the air nozzles 222 to blow out pulsed high-temperature compressed gas while simultaneously allowing the blown pulsed high-temperature compressed gas to swing along the vertical direction of the welding knife to perform pulsed cleaning of the entire welding knife, thereby further improving the cleaning efficiency and cleaning quality of the welding knife.

[0066] Preferably, multiple slide blocks 2213 are provided, and the multiple slide blocks 2213 are evenly arranged around the circumference, thereby improving the stable support of the transmission ring 2245, enabling the transmission ring 2245 to rotate stably, and then driving the multiple air nozzles 222 to swing stably between 0° and 90° in the vertical direction. This allows the air nozzles 222 to blow out pulsed high-temperature compressed gas while simultaneously swinging the pulsed high-temperature compressed gas along the vertical direction of the welding knife to perform pulsed cleaning of the entire welding knife, thereby further improving the cleaning efficiency and cleaning quality of the welding knife.

[0067] Example 4

[0068] Because cleaning unit 2 uses high-temperature compressed gas to purge the welding knife for rapid cleaning, molten waste wax on the welding knife will splash onto the inner wall of the working chamber of housing 1, easily accumulating there. Therefore, it is necessary to clean the accumulated waste wax on the inner wall of the working chamber in a timely manner to avoid adverse effects when cleaning unit 2 cleans the welding knife; Embodiment 4 is a further improvement based on Embodiment 1, Embodiment 2, or Embodiment 3, such as... Figure 1 As shown, the welding knife cleaning device also includes a recycling unit 3, which is installed on the housing 1. It is used to clean the waste wax that splashes onto the inner wall of the working chamber at any time, so as to avoid the waste wax from accumulating on the inner wall of the working chamber after splashing, thus achieving convenient and efficient cleaning without manual cleaning. At the same time, the recycling unit 3 can also collect the waste wax, thereby realizing the recycling of waste wax, protecting the environment and saving resources.

[0069] Preferably, the housing 1 is further provided with a water outlet, which is connected to the working chamber.

[0070] Preferably, such as Figure 11 and Figure 12As shown, the recycling unit 3 includes a water tank 31, a circulation pump 32, and a water storage chamber 33. The water tank 31 is located at the outlet of the housing 1 and is used to collect and store water. The circulation pump 32 is used to transport the water from the water tank 31 to the water storage chamber 33, realizing water recycling and avoiding water waste. The water storage chamber 33 is located above the working chamber and is used to temporarily store water. Multiple micropores are provided at the connection between the water storage chamber 33 and the inner wall of the working chamber, allowing water to pass through. The water temporarily stored in the water storage chamber 33 can flow to the inner wall of the working chamber, thereby forming a water curtain on the inner wall of the working chamber. When the molten waste wax on the welding knife splashes onto the inner wall of the working chamber, the water curtain causes the waste wax splashed onto the inner wall of the working chamber to cool and solidify quickly. Due to the flow of the water curtain, the solidified waste wax will flow with the water curtain, thereby avoiding accumulation on the inner wall of the working chamber. This allows for the timely cleaning of waste wax splashed onto the inner wall of the working chamber, which is convenient and efficient. Furthermore, the water flow carries the waste wax out from the outlet and into the water tank 31.

[0071] Preferably, the recycling unit 3 further includes a filter screen 34, which is disposed in the water tank 31 to filter the water flowing out from the outlet, thereby realizing the collection of waste wax and the filtration of water, ensuring water cleanliness, and avoiding clogging of the micropores on the water storage chamber 33.

[0072] Preferably, the inner walls of the working chamber of the housing 1 are inclined surfaces, so as to ensure that the water flowing out from the micropores can fall on the inner walls of the working chamber and form a continuous water curtain. This effectively prevents the solidified waste wax from accumulating on the inner walls of the working chamber, and also facilitates the water curtain to converge into a water flow, so that the water flow can carry the waste wax from the outlet into the water tank 31, making it convenient to collect the waste wax.

[0073] Preferably, the bottom surface of the working chamber of the housing 1 is an inclined surface, and the water outlet is inclined, which is conducive to the water curtain converging into a water flow, increasing the water flow speed, and making it convenient for the water flow to carry the waste wax from the water outlet into the water tank 31, so as to facilitate the collection of waste wax.

[0074] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
