Problems solved by technology

However, the production of steel pipes of different specifications requires frequent replacement of the ejector rod. At present, the connection between the inner water pipe of the ejector rod and the driving water pipe of the ejector trolley is generally connected by flange bolts. The disassembly is cumbersome and takes a long time.

Abstract

The invention discloses an axial-force-transmittable quick joint device for a water cooling pipe inside an ejector rod. The axial-force-transmittable quick joint device for a water cooling pipe insidean ejector rod is characterized by consisting of an inner joint body, a clamp plate, a sealing ring, an opening pin, a rotary pin shaft and an outer joint body. An internal cylindrical hole of original equipment is used for combination, and reliable connection and axial-force-transmittable effects are achieved; the sealing ring achieves a reliable sealing effect; and the leakage of cooling wateris prevented, so that the cooling water can reach a position to be cooled. The fast joint device provided by the invention has the advantages that the fast replacement of the ejector rod can be realized; 10 to 15 minutes can be saved during each time of ejector rod replacement; and in addition, the cooling water conveyance and the ejector head removal and tight locking can be completely met.

Description

technical field [0001] The invention relates to the technical field of steel pipe production, in particular to a quick coupling device for an internal water-cooled pipe of a ejector rod capable of transmitting axial force; it is a piercing process and a plug circulation process, and the cooling water pipe used for removing the plug in the inner water-cooled ejector rod is fast The joint changing device can realize the function of quick replacement of the ejector pin, shorten the replacement time of the ejector pin, and improve the production efficiency of the production line. Background technique [0002] At present, in the piercing process of all steel pipe production lines, in order to improve the service life of the plug and ensure the quality of the capillary tube, it is more and more common to use the plug circulation technology; tight function. However, the production of steel pipes of different specifications requires frequent replacement of the ejector rods. At pres...
