Description

Technical Field

[0001] The utility model relates to the technical field of artificial crystal furnaces, in particular to a vibration-proof device for processing an auxiliary furnace chamber of a crystal furnace. Background Art

[0002] The auxiliary furnace chamber of the crystal furnace is one of the key components in the artificial crystal furnace. The auxiliary furnace chamber is a cylindrical cavity with a double-layer structure. After the cooling medium is introduced, it plays a role in cooling the furnace body. The auxiliary furnace chamber is provided with a front return frame in front and a side return frame on the side. The return frame is connected to the furnace door and the lifting device.

[0003] During the cutting process, conventional workpieces undergo elastic deformation in the direction of the force due to the cutting force. The weaker the rigidity of the workpiece, the greater the impact of the cutting force and heat. Since the auxiliary furnace chamber is a long cylindrical structure, when it is fixed on the machine tool, it is hollow as a whole and has insufficient rigidity. When subjected to cutting force or vibration, it will deform greatly. At present, when cutting the return frame on the auxiliary furnace chamber, the tool and the cylinder body resonate. The higher the speed, the more obvious the vibration, resulting in serious vibration marks, which in turn affects the surface finish and sealing effect of the return frame, seriously affecting the processing quality of the product; at the same time, the relevant dimensions of each return frame and end face cannot be guaranteed. In general, when similar problems occur, most people will adjust the cutting parameters and reduce the feed rate to compensate, but this solution not only affects the production and processing efficiency, but also the effect is not ideal, and it is difficult to meet the needs of mass production.

[0004] Therefore, it is particularly important to provide a vibration-proof device that does not require re-adjustment of parameters, can ensure processing efficiency, and can meet the needs of mass production. Summary of the invention

[0005] In order to overcome the shortcomings of the background technology, the utility model discloses a vibration-proof device for processing the auxiliary furnace chamber of a crystal furnace. The utility model can not only prevent vibration marks from occurring during the processing, ensure the processing size, and realize stable precision processing, but also improve the processing efficiency and meet the needs of mass production.

[0006] In order to achieve the above-mentioned purpose of the invention, the utility model adopts the following technical solutions:

[0007] A vibration-proof device for processing a crystal furnace auxiliary furnace chamber comprises support columns and support cross columns. The support cross columns are arranged in at least two groups, and each two groups of support cross columns are arranged at intervals. The left and right end caps of each group of support cross columns are respectively connected to the inner walls of the left and right side return frames of the crystal furnace auxiliary furnace chamber. At least two support columns are respectively arranged on the top of each group of support cross columns, and the upper end caps of each support column are respectively connected to the front return frame side wall in front of the crystal furnace auxiliary furnace chamber.

[0008] The vibration-proof device for processing the auxiliary furnace chamber of a crystal furnace comprises two supporting cross columns which are stacked up and down.

[0009] The vibration-proof device for the auxiliary furnace chamber of a crystal processing furnace has a spacing distance between each two groups of supporting cross columns of 400 to 500 mm.

[0010] The anti-vibration device for processing the auxiliary furnace chamber of the crystal furnace, the upper end of the support column is spot-welded to the front return frame side wall in front of the auxiliary furnace chamber of the crystal furnace, and the lower end of the support column is spot-welded to the support cross column.

[0011] The vibration-proof device for processing the auxiliary furnace chamber of the crystal furnace, the left and right end caps of the supporting cross column are spot-welded to the inner walls of the side return frames on the left and right sides of the auxiliary furnace chamber of the crystal furnace.

[0012] By adopting the above technical solution, the beneficial effects of the utility model are:

[0013] The utility model supports the auxiliary furnace chamber through supporting columns and supporting cross columns, thereby increasing the strength of the furnace body, increasing the vibration resistance during vibration, reducing the vibration fluctuation frequency, and effectively avoiding the resonance between the tool and the cylinder, avoiding the vibration knife marks during the processing, ensuring the roughness of each processing surface, improving the processing quality, greatly improving the processing efficiency, stabilizing the workpiece processing performance, and being suitable for large-scale promotion and application.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] Combined with Figures 1-2 The utility model discloses a vibration-proof device for processing a crystal furnace auxiliary furnace chamber, comprising a supporting column 2 and a supporting cross column 3. A front return frame 1 is arranged in front of a furnace body 5 of the crystal furnace auxiliary furnace chamber, and side return frames 4 are symmetrically arranged on the left and right sides. The side frames 4 protrude to the outside of the furnace body 5. At least two groups of supporting cross columns 3 are arranged on the inner walls of the side return frames on the left and right sides. Each two groups of supporting cross columns 3 are arranged at intervals. The supporting cross columns 3 are hollow or solid structures. The left and right end heads of each group of supporting cross columns 3 are respectively connected to the inner walls of the side return frames 4 on the left and right sides of the crystal furnace auxiliary furnace chamber. Wall, at least two supporting columns 2 are vertically arranged on the top of each group of supporting cross columns 3, the supporting cross columns 3 are vertically connected to the supporting columns 2, the supporting columns 2 are hollow structures, and the upper ends of each supporting columns 2 are respectively connected to the side walls of the front return frame 1 in front of the auxiliary furnace chamber of the crystal furnace. The addition of supporting columns 2 and supporting cross columns 3 provides support for the front return frame 1 and the side frame 4 to be processed, which on the one hand increases the rigidity of the processing surface and overcomes the influence of cutting force, and on the other hand can increase the vibration resistance of the vibration pair during vibration, thereby reducing the vibration fluctuation frequency and reducing the vibration of the tool.

[0021] Taking the auxiliary furnace chamber cavity with a processing diameter of φ550mm and a length of 2600mm as an example, flanges are welded at both ends of the auxiliary furnace chamber, and there is a sandwich in the middle. When cutting the front return frame 1 with a length of 1600mm and a width of 180mm, the rough machining cutting parameters are: speed 1500r / min, feed 800mm / min, the tool used is a D32 straight shank machine end mill, and the cutting amount is 0.25mm. Severe chatter marks appeared during processing; adjusting the cutting parameters, feed 200mm / min, cutting amount 0.05mm, still serious chatter marks appeared, and when the roughness tester was used to test the machined surface, it was found that the roughness was Ra6.3, which seriously affected the sealing effect. It can be found that by adjusting the cutting parameters, the insufficient roughness of the machined surface caused by the vibration of the workpiece cannot be avoided.

[0022] After installing the shock absorbing device of the utility model, the machine was processed again with the same cutting parameters; the rough machining cutting parameters were: speed 1500r / min, feed 800mm / min, the tool used was a D32 straight shank machine end mill, and the cutting depth was 0.25mm. During the machining, coarser knife marks appeared. When the machined surface was tested with a roughness detector, it was found that the roughness was Ra6.3. The cutting parameters were adjusted, the feed was 200mm / min, the cutting depth was 0.05mm, and the machined surface was tested with a roughness detector. It was found that the roughness was Ra1.6, and the finish of the machined surface was significantly improved, providing good support for subsequent machining.

[0023] Further, if Figure 1 As shown, the supporting cross column 2 is set to two, and the supporting cross column 2 is a square hollow or solid structure. The two supporting cross columns 2 are stacked up and down, and the two end heads of the upper supporting cross column 2 are fixed to the upper inner walls of the side return frames 4 on the left and right sides, and the two end heads of the lower supporting cross column 2 are fixed to the lower inner walls of the side return frames 4 on the left and right sides. The two ends of the upper and lower supporting cross columns 2 are fixed to connect the side return frames 4 on both sides, thereby increasing the strength of the side return frames 4 and the vibration resistance of the pair.

[0024] Further, if Figure 2 As shown, the longer the auxiliary furnace chamber body 5 is, the greater the vibration generated. According to the length of the auxiliary furnace chamber body 5, a group of supporting horizontal columns 3 is arranged every 400 to 500 mm, and at least two supporting columns 2 are vertically arranged on each group of supporting horizontal columns 3 to increase the overall rigidity of the auxiliary furnace chamber.

[0025] Further, if Figure 1 As shown, the upper end of the support column 2 is spot-welded to the inner wall of the front return frame 1 in front of the auxiliary furnace chamber of the crystal furnace, and the lower end of the support column 2 is spot-welded to the support cross column 3, which is convenient for installation and disassembly and can be reused many times.
