Double-way pipe fitting groove pressing machine

Abstract

The invention discloses a double-way pipe fitting groove pressing machine and relates to the technical field of processing of a groove of a pipe fitting. The double-way pipe fitting groove pressing machine comprises a fixed pedestal; the two ends of the fixed pedestal are in slip connection with movable pedestals correspondingly; the sides, close to each other, of the two movable pedestals are rotatably connected with supporting rollers correspondingly; the two supporting rollers are coaxial; driving mechanisms for driving the supporting rollers to rotate are arranged at the ends, far away from each other, of the two supporting rollers correspondingly; groove pressing wheels which are in slip connection with the pedestal are arranged on the circumferential outer sides of the supporting rollers; the axis direction of the groove pressing wheels is as same as that of the supporting rollers; and the pressing wheels can abut against the circumferential surfaces of the supporting rollers. The double-way pipe fitting groove pressing machine solves the problems of high labor intensity, tedious operation and low processing efficiency when the two ends of the pipe fitting need to be subjected to groove processing in the prior art, and achieves the advantages of capability of processing grooves at the two ends of the pipe simultaneously, low labor intensity, simplicity in operation and convenience in use.

Description

technical field [0001] The invention relates to the technical field of groove processing of pipe fittings, in particular to a two-way pipe fitting grooving machine. Background technique [0002] The pipe fitting grooving machine can also be called a rolling groove machine. It is a special tool for pretreatment of pipes when grooved joints are used as pipe connectors. The principle of pipe fittings is that the rotating concave pressure wheel drives the pipe to rotate, and the convex pressure wheel Under the action of the oil cylinder, the pipe is slowly pressurized to form the required groove for installation. It can be used for the installation of pipes such as fire protection, tap water, and mines. [0003] The existing Chinese utility model patent whose authorized notification number is CN2925674Y can be referred to, which discloses a pipe fitting groove machine, which includes a frame arranged on a base, and a main shaft and a radial ring are rotatably arranged on the fra...

AI Technical Summary

Problems solved by technology

[0004] When the above-mentioned pipe fitting grooving machine is used, one end of the processed pipe fitting is set on the supporting wheel, and then the driving groove wheel is driven downward to contact the pipe fitting, and then the supporting wheel is used to drive the pipe fitting to rotate, and the pipe fitting is completed by the groove wheel Grooving, but when it is necessary to groove both ends of the pipe fittings, using the above-mentioned pipe fitting grooving machine, the operator first needs to manually set the pipe fittings on the tugboat, and then groove one end of the pipe fittings first Processing, after the processing is completed, the operator manually removes the pipe fittings, and manually re-sets the other end of the pipe fittings on the supporting wheel, and then performs processing again. During the processing, the operator needs to set and remove the pipe fittings several times , high labor intensity, cumbersome operation and low processing efficiency
