[0002] Castings vary in size. Small-sized castings can be cut at a low position using a cutting machine. However, for large-sized castings, due to the high height of the riser position, high-position cutting operations are required. Currently, there are two methods for high-position cutting operations. One is to suspend the cutting machine and then the worker operates the cutting machine. The other is that the worker stands on a raised platform to operate the cutting machine. Neither method is very convenient. The stability, safety, and convenience of the cutting operations in both the former and the latter are not good, and the sparks generated during cutting also affect the cutting operation.

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0025] Embodiment:

[0026] Please refer to Figure 1 - Figure 2, the present utility model provides a casting riser cutting device, which includes a mobile trolley 1. Moving wheels 2 are movably installed on both sides of the mobile trolley 1. The bottom of the mobile trolley 1 is recessed. A through groove is formed through the mobile trolley 1. An extension pipe 3 is fixedly installed at the upper end position of the through groove of the mobile trolley 1. An internally threaded pipe 4 is communicated and arranged on one side of the extension pipe 3. A positioning crank 5 is threadedly installed at the position of the internally threaded pipe 4. A lifting column is installed at the extension pipe 3. A cutting machine 6 is fixedly installed at the top of the lifting column. A rotating ring 7 is movably installed below the cutting machine 6 at the top of the lifting column. A visible plastic baffle 8 is fixedly installed on one side of the rotating ring 7 through a bracket. A push frame 9 is installed on the mobile trolley 1.

[0027] Specifically, the inner cavity size of the extension pipe 3 is the same as the size of the through groove. The outer surface of the lifting column is in contact with the inner wall of the extension pipe 3 to maintain the stability of the lifting column and avoid generating shaking gaps.

[0028] Specifically, as Figure 1 shown, the positioning crank 5 is a continuously bent structure. The rod section of the positioning crank 5 connected to the internally threaded pipe 4 is an externally threaded rod, which is convenient, labor-saving for manually fixing and releasing the lifting column.

[0029] Specifically, the edge of the cutting disc of the cutting machine 6 is located outside the mobile trolley 1. If the mobile trolley 1 walks close to the casting, it is convenient for the cutting disc of the cutting machine 6 to contact the riser and cut off the riser.

[0030] Specifically, as Figure 1 shown, the top of the visible plastic baffle 8 is higher than the cutting disc of the cutting machine 6, which can block the sparks.

[0031] Working principle:

[0032] When in use, first fix the casting with the riser position facing up. Then, according to the position of the bottom of the riser, move the lifting column upward to move the cutting disc of the cutting machine 6 to the height position of the bottom of the riser. Then shake the positioning crank 5. The externally threaded rod of the positioning crank 5 presses and fixes the lifting column to prevent it from sliding down. Rotate the visible plastic baffle 8 according to the position where the sparks will face the worker during cutting. The worker holds the push frame 9 on the ground and pushes the mobile trolley 1 to move, so that the cutting disc of the cutting machine 6 cuts off the casting riser.

[0033] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
