A punching device suitable for steel pipes of different diameters

Abstract

The invention discloses a perforating device suitable for steel tubes with different diameters. The perforating device comprises a base, a clamping device and rolling adjustment devices symmetrically arranged on the front and back sides of the clamping device are arranged at the end face of the top of the base, and a perforating rack is arranged at the position, between the clamping device and the back rolling adjustment device, of the base; a first rolling groove and a second rolling groove which are arranged in a bilateral symmetry manner are arranged in each rolling adjustment device, a separating plate is arranged between each first rolling groove and the corresponding second rolling groove, the first rolling grooves and the second rolling grooves are each internally provided with a bearing piece, and the bearing pieces on the left and right sides are each internally provided with rollers with taper face sides oppositely arranged; a lifting sliding cavity is arranged in the clamping device in a manner of being communicated with the base at the bottom of the clamping device, and a lifting sliding piece is arranged in the lifting sliding cavity; and through grooves are symmetrically arranged on the left and right sides of the top of the clamping device, and a driving sliding cavity is arranged in the lifting sliding piece. The perforating device is simple in structure and convenient to operate, and the perforating accuracy and stability are improved.

Description

Technical field [0001] The invention relates to the technical field of steel pipe processing, in particular to a punching device suitable for steel pipes of different diameters. Background technique [0002] The positioning and locking of the round steel pipe during the drilling process is very important, because inaccurate positioning will cause the hole center to deviate, and the insecure locking will also cause the hole center to deviate due to vibration during the drilling process. Mass production requires not only accurate punching but also fast positioning. At present, cylinders are mainly used to achieve rapid locking, but this method can only ensure the locking of the chuck to the steel pipe, and the locking at this location cannot guarantee the punching process The stability of the whole steel pipe in the middle, it is easy to cause the steel pipe in the hole to vibrate. If the degree of locking is not controlled, the drill bit is easy to wear and break, the hole surface...

Problems solved by technology

[0002] The positioning and locking of circular steel pipes during the drilling process is very important, because inaccurate positioning will lead to the deviation of the hole center, and insecure locking will also cause the hole center to deviate due to vibration during the drilling process. Mass production requires not only accurate drilling but also fast positioning. At present, the cylinder is mainly used to achieve fast locking, but this method can only ensure the locking of the chuck part to the steel pipe, and the locking at this position cannot guarantee the fast locking during the drilling process. The stability of the entire steel pipe in the hole can easily cause the steel pipe in the drilling to vibrate. If the degree of locking is not controlled, the drill bit is easy to wear and break, the hole surface is rough, the hole diameter is too large, the hole shape is not round or inclined to one side, etc. In addition, the locking device and position adjustment device of traditional steel pipe drilling processing equipment have a single structure, which cannot be adjusted according to steel pipes of different diameters.
