Description

Technical Field

[0001] The utility model relates to the technical field of pipe fitting processing, in particular to a pipe fitting groove pressing machine. Background Art

[0002] A fire extinguisher is a common fire-fighting tool, which generally includes a cylinder, a valve body, a connecting pipe and a trumpet nozzle. The connecting pipe is generally a hose. The trumpet nozzle and the valve body are connected, and the pressure handle on the valve body is pressed. The valve body passes through a siphon tube, so that the fire extinguishing agent in the cylinder passes through the hose and is sprayed out from the trumpet nozzle to extinguish the fire. In order to facilitate the operator to adjust the direction of the trumpet nozzle, current fire extinguishers generally connect a metal connecting elbow between the trumpet nozzle and the connecting pipe.

[0003] When the connecting elbow and the trumpet nozzle are installed together, in order to ensure the stability of the connecting part between the connecting elbow and the trumpet nozzle, and at the same time to ensure the sealing of the connecting part, it is usually necessary to perform grooving treatment on the connecting elbow through a die-casting machine. The working principle is: the connecting elbow is sleeved on the rotating wheel of the grooving machine, and the connecting elbow is driven to rotate by the rotating wheel. The lower pressing wheel in the grooving machine moves vertically downward through the hydraulic pump to squeeze the outer wall of the connecting elbow, and as the rotating wheel rotates, an annular groove with a certain depth is formed on the outer wall of the connecting elbow, thereby completing the grooving treatment of the connecting elbow.

[0004] In the above scheme, the existing groove pressing machine can only perform groove pressing on connecting elbows of one specification, which has great limitations and low practicality. Utility Model Content

[0005] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a pipe grooving machine, which is equipped with a moving mechanism so that pipes of different specifications can be grooved, thereby solving the problem that the prior art can only groove pipes of one specification and has great limitations, thereby improving practicality.

The rotation of the second sprocket drives the first sprocket to rotate through the chain, thereby driving the cam to rotate. The rotation of the cam squeezes one end of the front and rear moving components, thereby driving the front and rear moving components to move.

[0014] The utility model is further configured as follows: the forward and backward moving component includes a first moving rod inserted into the lower end of the frame, one end of the first moving rod is rotatably connected to the first pulley, the first pulley and the cam abut against each other, the other end of the first moving rod passing through the frame is sleeved with a first compression spring, one end of the first compression spring is fixed to the side wall of the frame, the other end of the first compression spring is fixed to the end of the first moving rod, a protrusion is fixed on the side wall of the first moving rod, and one end of the left and right moving component abuts against the protrusion.
