[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] For example, see Figure 1-Figure 4 The present invention provides a technical solution: a cutting device for medical device production, comprising a bottom plate 1, a working box 2 is fixedly connected to the top of the bottom plate 1, a welding head 3 is rotatably connected to the top of the working box 2 through a rotating shaft, a spray welder 4 is fixedly connected to the top of the welding head 3, a conducting mechanism 6 is provided on the surface of the welding head 3, a connecting groove 5 is provided on the surface of the working box, and further comprising: The transmission mechanism 6 includes a transmission plate 601, one end of which is fixedly connected to the surface of the welding head 3, a conduction block 603 is slidably connected to the inner wall of the transmission plate 601, a feed pipe 602 is fixedly connected to the top of the conduction block 603, one end of the feed pipe 602 away from the conduction block 603 is fixedly connected to the inner wall of the spray welder 4, and a compression pipe 604 is fixedly connected to the bottom of the transmission plate 601. The oxygen pressure reducer is adjusted through the oxygen bottle valve inside the welding head 3 to make the output pressure reach the specified working pressure range. Then open the gas bottle valve inside the spray welder 4, adjust the gas pressure reducer, and adjust the gas pressure to a suitable range. Then open the gas valve on the spray welder 4, so that the gas is transferred into the inside of the conduction block 603 through the feed pipe 602, and ignites through the internal igniter of the conduction block 603, so that the gas flame is ejected from the inside of the spray plate 6051.

[0024] The cleaning assembly 605 further includes a jet plate 6051 fixedly connected to the bottom of the conduction block 603, a plug ring 6052 fixedly connected to the left side of the jet plate 6051, a material storage tank 6053 fixedly connected to the right side of the jet plate 6051, a spray pressure pipe 6054 fixedly connected to the surface of the material storage tank 6053, a spray block 6056 fixedly connected to the surface of the spray block 6056, a drainage ring 6055 fixedly connected to the surface of the spray block 6056, and the drainage ring 6055 is away from the spray block 6056. One end of the compression tube 604 is fixedly connected to the inner wall of the storage tank 6053, and one end of the compression tube 604 is slidably connected to the inner wall of the injection tube 6054. The internal thruster of the transmission plate 601 is remotely started, thereby driving the conduction block 603 to slide outward inside the transmission plate 601, and the surface of the medical device is flame-cut by spraying a gas flame from the inside of the jet plate 6051. When the jet plate 6051 slides outward, one end of the compression tube 604 is squeezed, so that one end of the compression tube 604 bends inward and squeezes the internal compression film of the injection tube 6054.

[0025] A storage cavity is provided inside the storage tank 6053, and an acid solution is poured into the storage tank 6053. The interior of the spray block 6056 is connected to the interior of the storage tank 6053 through the drainage ring 6055. When the interior of the spray tube 6054 is compressed, air pressure is generated to push the internal acid solution of the storage tank 6053, so that the acid solution inside the storage tank 6053 is injected into the spray block 6056 through the drainage ring 6055, and finally the acid solution is sprayed into the cutting surface of the medical device from the bottom spray hole of the spray block 6056, and the cutting surface is pickled with the acid solution to remove the welding slag. Since the squeezing force generated by one end of the compression tube 604 on the interior of the spray tube 6054 is limited when it is initially compressed, the acid solution inside the storage tank 6053 will not be pushed by the air pressure and discharged outward.

[0026] A compression film is installed inside the spray tube 6054, and one end of the compression tube 604 can be extended and retracted toward the inside of the spray tube 6054. The stronger the compression degree at one end of the compression tube 604 is, the stronger the extrusion force on the compression film inside the spray tube 6054 will be. As a result, the acid solution inside the storage tank 6053 will be sprayed out from the bottom of the spray block 6056. This will prevent the acid solution from being sprayed out immediately, thereby affecting the cutting surface of the medical device. When the surface of the medical device is cut by flame, the acid solution released subsequently can be sprayed onto the flame cutting surface to avoid the generation of welding slag on the cutting surface.

[0027] Example 2: Based on Example 1, continue to refer to Figure 5-Figure 6, the adjusting mechanism 7 includes a mounting plate 701 fixedly connected to both sides of the working box 2, the inner wall of the mounting plate 701 is rotatably connected to a push arm 702, one end of the push arm 702 is rotatably connected to a covering block 704 through a rotating shaft, and connecting rods 705 are fixedly connected to both sides of the inner wall of the covering block 704, and one end of the connecting rod 705 away from the covering block 704 is slidably connected to the inner wall of the connecting groove 5, and the top of the covering block 704 is fixedly connected to a sliding frame 703, and the inner wall of the sliding frame 703 is provided with a positioning mechanism 8, and the two ends of the medical device are inserted into the inner wall of the covering block 704, and the two ends of the medical device will come into contact with the inner wall of the clamping block 7063, and the inside of the clamping block 7063 is squeezed by the two ends of the medical device, so that the clamping block 7063 receives The extrusion causes one end of the telescopic membrane 7062 to be squeezed, so that one end of the telescopic membrane 7062 is expanded and contracted inward, and the two ends of the medical device are clamped and fixed by the clamping blocks 7063 on both sides of the inner wall of the covering block 704, and then the pushing arm 702 is pushed to the top, so that one end of the pushing arm 702 rotates upward on the inner wall of the mounting plate 701, and the covering block 704 is driven to move to the top by one end of the pushing arm 702, and the medical device on the inner wall of the covering block 704 is moved close to the bottom of the jet plate 6051. When the covering block 704 is moving to the top, one end of the connecting rod 705 will slide upward on the inner wall of the connecting groove 5, thereby maintaining the stability of the medical device inside the covering block 704, allowing the medical device to always remain parallel, so that the flame can cut the surface of the medical device.

[0028] The absorption component 706 includes a mounting pad 7061 fixedly connected to the bottom of the inner wall of the covering block 704, a telescopic film 7062 fixedly connected to the top of the mounting pad 7061, a clamping block 7063 fixedly connected to the end of the telescopic film 7062 away from the mounting pad 7061, a telescopic pad 7064 fixedly connected to the top of the mounting pad 7061, and an absorption tube 7065 fixedly connected to the top of the telescopic pad 7064. When the flame cuts the surface of the medical device, it will vibrate the surface of the medical device, and the generated vibration is transmitted into the telescopic film 7062 through the two ends of the medical device, so that the telescopic film One end of 7062 continuously expands and contracts inwardly. When one end of the expansion membrane 7062 expands and contracts inwardly, its internal space will be compressed and a pressure difference will be formed on the outside, thereby generating a negative pressure suction force which is transmitted into the absorption tube 7065 through the expansion pad 7064. The heat generated by the flame cutting device is absorbed through the absorption tube 7065. During the flame cutting process, the high-temperature flame will heat the metal material around the cutting area to form a heat-affected zone. This heat effect may cause a degradation in material properties. The heat in the heat-affected zone generated by the flame cutting medical device can be absorbed to avoid the degradation of material properties caused by the heat-affected zone.

[0029] Example 3: Based on Example 1, continue to refer to Figure 7-Figure 8 The positioning mechanism 8 includes a positioning block 801, both ends of which are slidably connected to the inner wall of the sliding frame 703, one end of the positioning block 801 away from the sliding frame 703 is fixedly connected to a sliding box 806, the top of the sliding box 806 is fixedly connected to a telescopic column 802, the top of the telescopic column 802 is fixedly connected to a clamping column 803, the inner wall of the sliding box 806 is slidably connected to a stretching block 804, the inner wall of the stretching block 804 is fixedly connected to an absorption ring 805, and one end of the stretching block 804 is provided There is a centralized component 807, which pushes the positioning block 801 so that the two ends of the positioning block 801 slide on the inner wall of the sliding frame 703. When the positioning block 801 slides to the bottom of the jet plate 6051, the telescopic column 802 is pulled upward to insert the clamping column 803 into the plug-in ring 6052 to fix the sliding box 806 to the bottom of the jet plate 6051. When the conduction block 603 slides on the inner wall of the transmission plate 601, the conduction block 603 will drive the positioning block 801 to slide on the inner wall of the sliding frame 703.

[0030] A telescope is installed on the top of the stretching block 804, and a heat inlet groove is opened on the surface of the stretching block 804. The stretching block 804 can be extended outward, and the flame ejected by the jet plate 6051 will enter the surface of the medical device through the inner wall of the focusing box 8071 for cutting. The heat flow generated by the flame on the inner wall of the focusing box 8071 will enter the interior of the stretching block 804 through the drainage groove 8074. The internal absorption ring 805 of the stretching block 804 can absorb the heat flow transmitted to the interior, which can reduce the range of the heat affected zone generated when the flame cuts the surface of the medical device, thereby avoiding the reduction of the surface toughness of the medical device.

[0031] The inner wall of the central box 8071 is provided with a drainage groove 8074, and the inner wall of the positioning plate 8075 can transfer heat energy into the central box 8071 through the drainage groove 8074. When the flame flows inside the central box 8071, the heat generated by the flame will be absorbed by the inside of the absorption membrane 8072, and the inside of the absorption membrane 8072 will expand outward after absorbing the heat and push the positioning plate 8075, thereby driving the positioning plate 8075 to move to the other side of the central box 8071.

[0032] The centralizing component 807 includes a centralizing box 8071, which is fixedly connected to one end of the stretching block 804. A suction film 8072 is fixedly connected to the left side of the inner wall of the centralizing box 8071. A positioning plate 8075 is fixedly connected to one end of the suction film 8072. A resistance block 8073 is fixedly connected to the inner wall of the positioning plate 8075. A drainage groove 8074 is provided on the inner wall of the positioning plate 8075. When the positioning plate 8075 moves toward the inner wall of the centralizing box 8071, the resistance block 8073 on the inner wall of the positioning plate 8075 will reduce the flow range of the flame in the centralizing box 8071, thereby concentrating the energy of the flame. Since the energy distribution during flame cutting of medical devices is not concentrated enough, the cutting surface is often rough, which can improve the accuracy of the flame cutting the surface of the medical device.
