Description

Technical Field

[0001] The utility model relates to the technical field of pipe processing equipment, in particular to a chamfering knife holder of a double-head chamfering machine. Background Art

[0002] Pipes are widely used in the processing and manufacturing industry. After the pipes are cut, there will be burrs on the cut ends. Therefore, in order to remove the burrs on the pipes or to facilitate the welding of the pipes, a chamfering machine is needed to chamfer the ends of the pipes. However, the existing chamfering machines can only chamfer one end of the pipe first and then the other end of the pipe. Since the two ends of the pipe are chamfered separately, the feed amount of the tool during chamfering is controlled by the operator, which makes it difficult to ensure the consistency of the chamfering accuracy at both ends of the round pipe, and also reduces the processing efficiency of chamfering the pipe.

[0003] For example, the patent with application number CN201711269365.4 discloses a double-head chamfering machine, including a frame, a base arranged above the frame, and a slide groove arranged on the base, a longitudinal beam in an inverted L shape is arranged in the middle of the base, a clamping device for fixing the pipe to be chamfered is arranged below the top of the longitudinal beam, sliding devices are arranged at both ends of the base, a cutting device is arranged on the sliding device, the sliding device includes a stepping motor, a screw rod, and a slider, the stepping motor is fixedly connected to the base, the slider is located in the slide groove of the base, one end of the screw rod is connected to the stepping motor, and the other end is connected to the slider; the double-head chamfering machine has the advantages of being able to perform chamfering processing on both ends at the same time, high chamfering accuracy, and improving the efficiency of pipe chamfering processing, but there is no tool holder and protective device under the cutting device of the device, and there is a risk of injury when moving the chamfering knife.

[0004] This case was created to solve the above problems. Utility Model Content
