The present invention relates to a pipe punching device. The pipe punching device forms a hole in a pipe by manual work, and comprises: a punching part to form a hole in the pipe; a body having a punching part installation unit formed on a front end thereof to mount the punching part and a plurality of punching part storage units in which a plurality of punching parts are embedded; and an opening/closing cap to open and close the punching part storage units of the body. Also, the punching part comprises: a cylindrical punching unit formed on a front end thereof in a truncated cone shape; and a hollow hole formed in a longitudinal direction to guide separation pieces separated from the pipe during hole forming work. The rear end of the punching part is mounted on the punching part installation unit of the body. A separation piece guide hole is formed on the front end of the body and connected to the hollow hole of the punching part. A separation piece discharge unit is formed on the body to discharge the separation pieces coming from the separation piece guide hole to the outside. A support protrusion is formed on the body to support a thumb and an index finger of a worker. Therefore, since the separation pieces separated from the pipe during the hole forming work enter the hollow hole of the punching part and the separation piece guide hole of the body and are discharged to the outside through the separation piece discharge unit of the body, the present invention can smoothly form a hole on the surface of the pipe since the separation pieces do not enter into the pipe. The punching part storage units formed on the body can conveniently store punching parts of various forms or extra punching parts to provide the worker with convenience and allow the worker to manually form a hole in a pipe of a synthetic resin material conveniently and easily. |
