DETAILED DESCRIPTION
[0024] In order to make the technical means, creative features, purposes and effects of the present application clearer and easier to understand, the present application will be further described below in conjunction with the drawings and specific embodiments.
[0025] As shown in Figures 1 to 5 The present application provides a full-automatic launcher lubricating oil brazing cooling system, which comprises a lubricating oil blending and output device 2, a gas supply device (not shown in the figure) and a lubricating oil transmission device 3. The lubricating oil transmission device 3 comprises a conveying mechanism 32 and an oil-gas separation mechanism 33. The conveying mechanism 32 is provided with a gas conveying channel and an oil conveying channel. The gas conveying channel is in communication with the output end of the gas supply device (not shown in the figure), and the oil conveying channel is in communication with the output end of the lubricating oil blending and output device 2. The output end of the conveying mechanism 32 is provided with the oil-gas separation mechanism 33. The oil-gas separation mechanism 33 is used to extend into the cooling hole 11 of the brazing mold 1. The oil-gas separation mechanism 33 is provided with a gas injection channel 333 and an oil injection channel 334. The gas injection channel 333 is in communication with the gas conveying channel, and the oil injection channel 334 is in communication with the oil conveying channel. In use, the lubricating oil blending and output device 2 outputs the blended lubricating oil to the oil conveying channel, and the gas supply device (not shown in the figure) outputs gas to the gas conveying channel. Both of them are transmitted in the conveying mechanism 32, and finally are injected into the cooling hole 11 of the brazing mold 1 through the oil injection channel and the gas injection channel 333 of the oil-gas separation mechanism 33, respectively. The impurities generated after the combustion of the lubricating oil are removed by the output gas, thereby improving the welding quality of the product to be welded.
[0026] The lubricating oil transmission device 3 further comprises a guide head 31. The guide head 31 is fixed with the conveying mechanism 32 and is used to guide the conveying mechanism 32 to extend into the cooling hole 11 of the brazing mold 1.
[0027] The end of the conveying mechanism 32 away from the output end of the gas supply device (not shown in the figure) is recessed to form a groove. The oil-gas separation mechanism 33 is installed in the groove. The oil-gas separation mechanism 33 is located between the guide head 31 and the output end of the gas supply device (not shown in the figure). The guide head 31 ensures the stability of the conveying mechanism 32 during the insertion process, prevents deviation or damage, and thus ensures that the lubricating oil and gas can be accurately and correctly conveyed into the cooling hole 11, achieving efficient cooling and lubrication.
[0028] One end of the guide head 31 protrudes to form an insertion pipe 311. The insertion pipe 311 is inserted into the conveying mechanism 32. The conveying mechanism 32 is connected with the insertion pipe 311. The end of the guide head 31 close to the insertion pipe 311 forms a first step 312. The first step 312 is clamped with the oil-gas separation mechanism 33 in cooperation with the inner wall of the groove. The close cooperation between the first step 312 and the inner wall of the groove ensures that the oil-gas separation mechanism 33 does not loosen or deviate during the conveying process.
[0029] The guide head 31 comprises a first cylindrical section 314 and a second cylindrical section 315, the diameter of the first cylindrical section 314 is larger than that of the second cylindrical section 315, the first cylindrical section 314 is used for guiding the insertion of the guide head 31 into the cooling hole 11 of the brazing die 1, the second cylindrical section 315 is fixedly inserted into the insertion pipe 311, the second cylindrical section 315 forms a first step 312 at the end face close to the insertion pipe 311, the second cylindrical section 315 is fixed with the first cylindrical section 314, the first cylindrical section 314 forms a second step 313 at the end face close to the second cylindrical section 315, and the second step 313 is distanced from the oil-gas separation mechanism 33. The first cylindrical section 314 can accurately guide the insertion of the guide head 31 into the cooling hole 11 of the brazing die 1 due to the larger diameter, ensuring that the conveying mechanism 32 is aligned with the cooling hole 11, and guaranteeing the accuracy of subsequent oil-gas conveying. The second cylindrical section 315 is used for fixing the insertion pipe 311, the insertion pipe 311 is connected with the conveying mechanism 32, ensuring the stable combination of the conveying mechanism 32 and the guide head 31, so that they work more stably and reliably, and prevent the connection from loosening due to vibration or pressure change.
[0030] The gas conveying passage and the oil conveying passage are both L-shaped structures near the end of the guide head 31, the outlet of the gas conveying passage and the outlet of the oil conveying passage are both on the side wall of the gas conveying mechanism, and the outlet of the gas conveying passage and the outlet of the oil conveying passage are distanced in the axial direction of the gas conveying mechanism. The L-shaped structure changes the flow direction of the gas and the lubricating oil when they approach the cooling hole 11 of the brazing die 1, and the staggered layout of the outlets prevents mutual interference when the gas and the lubricating oil are sprayed out, avoiding the direct mixing of the gas and the lubricating oil at the end of the conveying.
[0031] The oil-gas separation mechanism 33 is a circular ring structure, the inner wall of the oil-gas separation mechanism 33 is recessed to form a gas ring groove 331 and an oil ring groove 332, the gas ring groove 331 and the oil ring groove 332 are distanced, the gas ring groove 331 is communicated with a gas jet passage 333, and the oil ring groove 332 is communicated with an oil jet passage 334. When the oil-gas mixture reaches the oil-gas separation mechanism 33, the gas and the lubricating oil enter the corresponding ring grooves respectively, and then are sprayed out along the respective passages, ensuring that the gas and the lubricating oil can accurately act on different parts of the cooling hole 11 of the brazing die 1 respectively, and improving the cooling and lubricating effect.
[0032] The gas ring groove 331 is communicated with a first outlet 335 and a second outlet 336, the first outlet 335 is located on the side wall of the oil-gas separation mechanism 33, the second outlet 336 is located on the end face of the oil-gas separation mechanism 33 close to the second step 313, the oil ring groove 332 is communicated with an oil jet port 337, and the oil jet port 337 is located between the first outlet 335 and the second outlet 336. The gas is sprayed out from the first outlet along the side wall to preliminarily cool the inner wall of the cooling hole 11 of the brazing die 1, and at the same time, the gas is sprayed out from the second outlet to the end face direction to further deeply cool the inside of the cooling hole 11, realizing more comprehensive cooling and effectively expanding the coverage range of the gas.
[0033] The angle between the center line of the oil injection port 337 and the axis of the oil-gas separation mechanism 33 is an acute angle, and the oil injection port 337 extends in the direction of the guide head 31 after being communicated with the oil ring groove 332. The lubricating oil can cover the inner wall of the cooling hole 11 of the brazing die 1 at an inclined angle, so that the lubricating oil can fully enter the gap between the guide head 31 and the cooling hole 11 of the brazing die 1, ensuring that the inside of the cooling hole 11 is fully lubricated, reducing friction and heat generation.
[0034] Based on the idea of needing to spray lubricating oil and gas (on the premise that both lubricating oil and gas need to be sprayed to dry the guide head), the lubricating oil and gas are designed to be output from the conveying mechanism 32, and in order to separate the lubricating oil and gas in the conveying mechanism 32, the oil-gas separation mechanism 33 is designed to realize that the multiple gas injection channels 333 converge into the gas ring groove 331 and the multiple oil injection channels 334 converge into the oil ring groove 332, preparing for the subsequent first outlet 335, second outlet 336 and oil injection port 337. Since the number of gas injection channels 333 cannot be the same as the number of oil injection ports 337, and the oil injection port 337 has a certain inclination angle design, and the positions of the first outlet 335 and the second outlet 336 need to be arranged, so that the lubricating oil can be fully dried, the oil-gas separation mechanism 33 is designed to be installed on the conveying mechanism 32. Then, in order to make the lubricating oil fully enter the gap between the guide head 31 and the cooling hole 11 of the brazing die 1, so that the lubricating oil diffuses in the cooling hole 11, the angle between the center line of the oil injection port 337 and the axis of the oil-gas separation mechanism 33 is designed to be an acute angle, and the oil injection port 337 extends in the direction of the guide head 31 after being communicated with the oil ring groove 332, so that the oil injection port 337 has a tendency to spray oil towards the guide head 31, achieving the purpose of cooling and lubrication. Finally, in order to make the sprayed gas fully diffuse, the first outlet 335 and the second outlet 336 are arranged to make the air flow to each position of the cooling hole 11, ensuring the drying effect. The gap between the second step 313 and the second outlet 336 enables the gas to be sprayed out, so that the sprayed gas can fully enter the gap between the guide head 31 and the cooling hole 11 of the brazing die 1.
[0035] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced equivalently without departing from the purpose and scope of the present application, which should be covered in the scope of the claims of the present application.
