Description

Technical Field

[0001] This utility model relates to the field of electroslag remelting technology, and in particular to a band saw for electroslag remelting. Background Technology

[0002] Electroslag remelting is a method of smelting that uses the resistance heat generated when an electric current passes through molten slag as a heat source. Its main purpose is to improve the purity of metal and improve the crystallization of ingots. When processing electroslag remelting, it is necessary to cut it, which requires the use of a band saw for electroslag remelting.

[0003] The patent specification with publication number CN202317250U discloses a bidirectional horizontal band saw, comprising two horizontal band saws. The two horizontal band saws are movably mounted on a machine base with their backs facing each other. A workpiece clamping device and a drive device are respectively located on the machine base between the two horizontal band saws, and the drive device is connected to both horizontal band saws. The two horizontal band saws can simultaneously saw both ends of a workpiece, offering simple operation, high processing accuracy, and high efficiency.

[0004] While the above-mentioned technology allows for simultaneous sawing of both ends of the workpiece using two horizontal band saws, it is inconvenient to clamp the circular electroslag remelted material during sawing. This causes the electroslag remelted material to shift during sawing, affecting the sawing effect. Therefore, a band saw for electroslag remelting is needed to solve the above problems.

[0024] In a further preferred embodiment of this utility model, such as Figures 1-5 As shown: The pusher structure 6 includes a pusher plate 601, a screw 602, a guide rod 603, a guide sleeve 604, a threaded sleeve 605, and a mounting groove 606. The screw 602 is installed inside the placement seat 2. The guide sleeve 604 is installed on the outside of the screw 602. The pusher plate 601 is installed on the top of the guide sleeve 604. The mounting groove 606 is opened on both sides inside the placement seat 2. The guide rod 603 is installed inside the mounting groove 606. The guide sleeve 604 is installed on the outside of the guide rod 603. The top of the guide sleeve 604 is connected to the bottom of the pusher plate 601.

[0025] Specifically, in this embodiment: when sawing the circular electroslag remelted material, the electroslag remelted material is placed on the top of the placement seat 2.

During adjustment, the fixing rod 707 is held to move the clamping sleeve 703 inside the locking block 704, thereby adjusting the position of the clamping sleeve 703. When the clamping sleeve 703 is adjusted to a suitable position for clamping the electroslag remelting, the movement stops, and the nut 706 is rotated to the outside of the fixing rod 707 to complete the fixing of the clamping sleeve 703. After completion, the first cylinder 701 is activated to push the clamping sleeve 703 downward to adhere to the top of the electroslag remelter, thus clamping the electroslag remelter and preventing it from moving around during sawing. The bottom of the clamping sleeve 703 is equipped with ball bearings so that clamping the electroslag remelter does not affect its movement. After the electroslag remelter is clamped, the external motor starts the drive wheel 3 to rotate the saw blade 5.
