Rapid positioning and punching device for stainless steel pipe center hole

Abstract

The invention discloses a rapid positioning and punching device for a stainless steel pipe center hole. The device structurally comprises a supporting frame, a control electric box, a drilling machine, a drilling stabilization seat, a laser positioning machine, a rapid positioning device, a power motor, a steel pipe middle positioning sliding seat and a sliding rail, wherein the supporting frame is of a cuboid structure, the control electric box is installed at the left lower end of the supporting frame and is connected with the drilling machine and the power motor, and the drilling machine isconnected with the upper surface of the left end of the supporting frame. According to the device, a steel pipe can be clamped and pushed through the rear end of the device, so that a movable seat and a front end inserting groove of the rapid positioning device are connected and fastened, and an internal transmission structure is pushed; cutting marks are arranged on the surface of the front endof the steel pipe when the steel pipe enters the rapid positioning device, when the steel pipe moves to the other end opening of the rapid positioning device, the laser senses marks at the upper end and the lower end, so that a signal is transmitted to a control box to start the drilling machine, and then accurate positioning and punching can be achieved; and the internal transmission mechanism can enable the frame which clamps the steel pipe slightly to move front and back to save the cooling time for a drill, and the service life can be prolonged.

Description

technical field [0001] The invention relates to the field of fast positioning and punching devices, more precisely, it relates to a fast positioning and punching device for the central hole of a stainless steel pipe. Background technique [0002] In the production of seamless steel pipes, center hole positioning is required before hot-rolled piercing. Center hole positioning is to process a center hole with a certain depth and diameter on the end face of a round steel pipe in order to perforate the hot-rolled steel pipe. Locating the center hole is a very important link, because it plays a correct centering and guiding role for the subsequent piercing plug. But, present this stainless steel tube central hole fast positioning punching device equipment has the following disadvantages: [0003] If the clamping degree is not well controlled and the drill is drilled blindly, the drill bit is prone to wear and breakage; the positioning is not accurate, resulting in the deviation ...
