In order to facilitate understanding of the beveling machine, the following description is further made in connection with a specific working principle.

In this embodiment, the working method of the beveling machine includes the following steps:

step 1: the operator can rotate the angle plate 22 to a proper angle position relative to the angle bottom plate 21 in advance according to the required groove processing requirement, specifically, the operator firstly screws the unlocking bolt handle 25, then rotates the angle position of the adjusting swivel seat 24 (synchronously drives the angle plate 22 to perform angle adjustment), and screws the locking bolt handle 25 after the angle plate 22 is adjusted to the proper angle position, so that the angle position adjustment of the angle plate 22 is completed; wherein, during the angle adjustment, the operator can clearly and intuitively know the angle according to the angle scale line and the angle pointer 241; the larger the angle of rotation adjustment of the swivel base 24, the larger the bevel formed by grinding, whereas the smaller the angle of rotation adjustment of the swivel base 24, the smaller the bevel formed by grinding.

Step 2: the pipe to be machined is then placed on the gusset 22 and is traversed by means of the angled floor 21, so that the grinding wheel 11 is fed and ground relative to the pipe. Specifically, the angle bottom plate 21 moves transversely towards the first grinding assembly 1, the pipe fitting placed on the angle plate 22 and the grinding wheel 11 of the first grinding assembly 1 move transversely, so that a first groove is formed on one side of the end of the pipe fitting, then the angle bottom plate 21 moves transversely towards the second grinding assembly 1, the pipe fitting placed on the plate and the grinding wheel 11 of the second grinding assembly 1 move transversely, so that a second groove is formed on the other side of the end of the pipe fitting, and finally the angle bottom plate 21 moves transversely and is separated from the grinding assembly 1.

Step 3: the end of the pipe after grinding is ground and polished by the polishing component 3, specifically, an operator can take the pipe off the angle plate 22 at the moment, and then manually hold the pipe to contact the grinding position of the end of the pipe with the polishing grinding wheel 31 of the polishing component 3 for polishing; alternatively, by driving the angle bottom plate 21 to move laterally in the direction of the polishing member 3 (the end of the pipe needs to be ensured to avoid the grinding member 1 during the lateral movement), the pipe disposed on the gusset 22 is then brought into contact with the polishing wheel 31 of the polishing member 3 to perform polishing treatment, and in this way, automation operation is realized, which is more efficient but more costly.

And (3) finishing the grinding and polishing of the end part of the pipe through the steps 1-3, so as to form a smooth and flat groove.

Further, in order to improve the safety in the grinding process, a transparent baffle plate fixed on the frame 100 can be additionally arranged on the periphery of the grinding assembly 1, so that the metal scraps during grinding are prevented from being popped up to injure operators.

The above-described embodiments are merely preferred embodiments of the present utility model, and are not intended to limit the present utility model in any way.
