Description

Technical Field

[0001] The utility model belongs to the technical field of casting machines, and in particular relates to a high-precision continuous casting machine. Background Art

[0002] Continuous casting machines belong to the category of metal processing equipment, and are mainly used for traction casting of various shapes (solid bars, hollow tubes, plates, etc.) of precious metals (such as gold, silver, copper, etc.). This type of equipment is usually used in precious metal smelting, casting and other processes. It can melt precious metals and cast them into parts of the size required by customers, which is convenient for subsequent processing or application;

[0003] However, during use, the applicant discovered the following problems:

[0004] 1. The smelting barrel is welded with steel plates. Poor welding will cause water and air leakage in the smelting barrel;

[0005] 2. The traction structure is a single cylinder and a single roller, so the traction distance is short, and there is a risk of falling during the casting process. Utility Model Content

[0006] In view of the problems raised by the above background technology, the purpose of the utility model is to provide a high-precision continuous casting machine.

[0007] In order to achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0008] A high-precision continuous casting machine comprises a smelting barrel mounted on a machine body, the smelting barrel is integrally formed, a smelting cover is hingedly mounted on the smelting barrel, the smelting cover is provided with an observation window, and a traction mechanism is docked at the output end of the smelting barrel;

[0009] The traction mechanism comprises a tray mounted on the machine body, a rectangular frame mounted on the tray, a guide cylinder and two telescopic cylinders mounted in the rectangular frame, an adjusting screw being threadedly connected to the guide cylinder, a moving block being rotatably connected to the end of the adjusting screw, two first guide wheels being mounted on the moving block, and second guide wheels corresponding to the positions of the two first guide wheels being mounted on the output ends of the two telescopic cylinders respectively;

[0010] The tray is provided with a through hole corresponding to the output end of the smelting barrel, a U-shaped mounting plate is installed on the lower side of the tray, and a guide wheel group is longitudinally provided on the U-shaped mounting plate;

[0011] A material receiving box located at the lower side of the U-shaped mounting plate is installed at the bottom of the machine body.

[0012] It is further defined that the guide wheel group includes three slide grooves, the slide groove located at the top is equipped with two third guide wheels, and the two slide grooves located on the lower side are each equipped with a fourth guide wheel. The third guide wheel and the fourth guide wheel can still rotate in the axial direction after the axial position is fixed. Such a design can realize directional casting in multiple angles and directions, thereby enhancing adaptability for use.

[0013] It is further defined that the rectangular frame is installed with a limit plate, and the limit plate is provided with a waist-shaped hole matching the second guide wheel. Such a design ensures the smooth movement of the second guide wheel while limiting the position.

[0014] It is further defined that a sealing and heat-insulating block is installed on the upper side of the rectangular frame at the output end of the smelting barrel. Such a design not only has the sealing and heat-insulating effects but also has the supporting effects, and can further serve the purpose of assisting the shaping of the molten metal.

[0015] It is further defined that positioning columns are installed on the upper side of the rectangular frame at the left and right sides of the smelting barrel, and the left and right sides of the smelting barrel are fixed to the positioning columns. Such a design strengthens the fixed support effect of the smelting barrel.

[0016] The beneficial effects of adopting the utility model are:

[0017] With the structural design of the utility model, compared with the single wheel in the prior art, the utility model uses two second guide wheels and two telescopic cylinders to cooperate, thereby increasing the traction distance and reducing the risk of falling during the casting process;

[0018] By adopting the structural design of the utility model, the smelting barrel is integrally formed without welding seams, and the problem of water leakage and air leakage is not likely to occur. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0027] like Figure 1 , Figure 2 , Figure 3 As shown, a high-precision continuous casting machine of the utility model comprises a smelting barrel 2 mounted on a machine body 1, the smelting barrel 2 is integrally formed, a smelting cover 3 is hingedly mounted on the smelting barrel 2, the smelting cover 3 is provided with an observation window 4, and a traction mechanism 5 is connected to the output end of the smelting barrel 2;

[0028] The traction mechanism 5 includes a tray 51 mounted on the machine body 1, a rectangular frame 52 is mounted on the tray 51, a guide cylinder 53 and two telescopic cylinders 54 are mounted in the rectangular frame 52, an adjusting screw 55 is threadedly connected to the guide cylinder 53, a moving block 56 is rotatably connected to the end of the adjusting screw 55, the moving block 56 is mounted with two first guide wheels 57, and second guide wheels 58 corresponding to the positions of the two first guide wheels 57 are respectively mounted at the output ends of the two telescopic cylinders 54;

[0029] The tray 51 is provided with a through hole 59 corresponding to the output end of the smelting barrel 2, and a U-shaped mounting plate 510 is installed on the lower side of the tray 51, and a guide wheel group is longitudinally provided on the U-shaped mounting plate 510;

[0030] A material receiving box 6 is installed at the bottom of the machine body 1 and is located at the lower side of the U-shaped mounting plate 510.

[0031] In this embodiment, when a high-precision continuous casting machine is used, precious metal is put into the smelting barrel 2, the smelting cover 3 is closed and then the smelting barrel 2 is started to smelt the precious metal;

[0032] The melted metal passes through the through hole 59 under its own weight and passes between the first guide wheel 57 and the second guide wheel 58. At this time, it is pulled by the first guide wheel 57 and the second guide wheel 58. The design of the two sets of guide wheels makes the pulling distance longer, and thus the problem of casting falling is not likely to occur. The pulled metal is pulled by the guide wheel group for the next step.

[0033] The distance between the first guide wheel 57 and the second guide wheel 58 can be adjusted. The first guide wheel 57 is adjusted by rotating the adjusting screw 55 to drive the moving block 56 to move in the rectangular frame 52, thereby driving the two first guide wheels 57 installed on the moving block 56 to move, and the movement of the second guide wheel 58 drives the telescopic cylinder 54 to operate. The adjustment is simple, fast and convenient.

[0034] Preferably, the guide wheel group includes three slide grooves 511, and the slide groove 511 located at the top is equipped with two third guide wheels 512, and the two slide grooves 511 located at the lower side are each equipped with a fourth guide wheel 513. The third guide wheel 512 and the fourth guide wheel 513 can still rotate in the axial direction after the axial position is fixed. Such a design can realize directional casting in multiple angles and directions and enhance adaptability. In fact, the auxiliary traction structure of the guide wheel group can also be considered according to specific circumstances.

[0035] Preferably, the rectangular frame 52 is installed with a limiting plate 514, and the limiting plate 514 is provided with a waist-shaped hole 515 matching the second guide wheel 58. Such a design ensures the smooth movement of the second guide wheel 58 while limiting the position. In fact, the length specification size of the waist-shaped hole 515 can also be considered according to the specific situation.

[0036] Preferably, a sealing and heat-insulating block 7 is installed on the upper side of the rectangular frame 52 at the output end of the smelting barrel 2. Such a design not only has the sealing and heat-insulating effect but also has the supporting effect, and further can also assist in the forming of the molten metal. In fact, sealing measures can also be considered according to specific circumstances.

[0037] Preferably, positioning columns 8 are installed on the left and right sides of the smelting barrel 2 on the upper side of the rectangular frame 52, and the left and right sides of the smelting barrel 2 are fixed to the positioning columns 8. This design strengthens the fixed support effect of the smelting barrel 2. In fact, the fixed support structure can also be considered according to specific circumstances.

[0038] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
