Perforating device applicable to steel tubes of different sizes

Abstract

The invention discloses a perforating device applicable to steel tubes of different sizes. The perforating device comprises a base. The end face of the top of the base is provided with a clamping device and rolling adjustment devices, wherein the rolling adjustment devices are arranged at the front side and the rear side of the clamping device in a symmetrical manner. A perforating rack is arranged at the position, between the clamping device and the rolling adjustment device at the rear side, on the base. Each rolling adjustment device is internally provided with a first sliding groove and asecond sliding groove which are symmetrical in the left-right direction. A partition plate is arranged between each first sliding groove and the corresponding second sliding groove. The first slidinggrooves and the second sliding grooves are each internally provided with a bearing component. Rolling wheels with the conical surface sides being opposite are arranged in the bearing components at theleft side and the right side. The clamping device is internally provided with an ascending-and-descending sliding cavity, wherein the ascending-and-descending sliding cavity communicates with the portion, at the bottom of the clamping device, inside the base. The ascending-and-descending sliding cavity is internally provided with an ascending-and-descending sliding component. Through grooves aresymmetrically formed in the left side and the right side of the top of the clamping device. The ascending-and-descending sliding component is internally provided with a driving sliding cavity. The perforating device is simple in structure and convenient to operate, and perforating precision and steadiness 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 sizes. Background technique [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 ...

[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.
