Problems solved by technology

However, when using a punching machine, due to the high pressure of punching, depressions will inevitably occur on the surface of the square tube around the hole; and due to the limitation of the punching process itself, burrs will occur on the opening edge of the hole, which requires post-processing

Embodiment Construction

[0018] see figure 1 , figure 2 , image 3 , a square tube drilling machine, including a base 1, a transmission mechanism 2 arranged on the base 1 for transmitting a square tube 3, a column 11 with one end fixed on the base 1, The crossbeam 12 fixed on the other end of the column 11, the drill bit 4 that can process the square tube 3 on the transmission mechanism 2, and the drill bit 4 that is arranged on the crossbeam 12 have many root, and the plurality of drill bits 4 are distributed along the extension direction of the square pipe 3, and the plurality of drill bits 4 are connected to a sliding bracket 5, and the sliding bracket 5 can be opposite to the column 11 is slidably arranged on the column 11. When processing is carried out, a plurality of drill bits 4 are processed at the same time, and a plurality of holes are processed at one time, thereby improving efficiency.

[0019] In detail, the lifting cylinder 13 with the lifting piston rod 14 is fixed on the beam 12,...

Abstract

The invention relates to a square pipe drilling machine, which comprises a base, a transmission mechanism, an upright post of which one end is fixed on the base, a beam fixed at the other end of the upright post, and drills arranged on the beam and capable of processing a square pipe on the transmission mechanism, wherein the plurality of drills are arranged along the extending direction of the square pipe and are connected on a sliding bracket; the sliding bracket can be arranged on the upright post in a sliding way relative to the upright post; and the cutting end face of a drill main body of each of the drills relative to the square pipe is provided with an annular groove taking an axis of the drill as an axis, so that a protrusion ridging outwards along the axis of the drill is formed in the center of the cutting end face. The square pipe drilling machine adopting the technical scheme can complete the processing of a plurality of holes on one square pipe, and the drills can drill at one time without pre-drilling positioning holes so as to reduce working procedures, shorten working hours and improve drilling efficiency.

Description

technical field [0001] The invention relates to a drilling machine for drilling holes in square pipes. Background technique [0002] In many existing applications, it is necessary to punch holes in square tubes, such as brackets for various shelves. If the traditional drill bit is used for drilling, although the processed hole has a beautiful appearance, it is necessary to pre-drill the positioning hole on the square pipe, otherwise the drill bit is easy to drill off, and the process is more complicated. In order to be able to form at one time and do not need to punch positioning holes in the early stage, the machine usually used to punch holes on square tubes is a punching machine. However, when using a punching machine, due to the high pressure of punching, depressions will inevitably occur on the surface of the square tube around the hole; and due to the limitation of the punching process itself, burrs will occur on the opening edge of the hole, which requires post-proce...
