The invention discloses a device for manufacturing holes in H-shaped steel. The device comprises a stand column, a first rotary arm, a second rotary arm, a lifting arm and a punch. Rotating shafts vertically arranged are fixed to the left end and the right end of the first rotary arm. The upper middle portion of the right end of the second rotary arm and the left end of the lifting arm are rotationally connected through a horizontal pin shaft. A hydraulic cylinder is hinged to the lower middle portion of the right end of the second rotary arm. The free end of a piston rod of the hydraulic cylinder is hinged to the lifting arm. The device for manufacturing the holes in H-shaped steel is provided with the two joints of rotary arms and the lifting arm so that the punch can carry out the pitching action in the vertical plane while the punch rotates in the horizontal plane. In addition, a weight equal to the punch in mass is arranged, and by means of a pull rope and the rotary arms, the moving space of the punch is large, and operation is flexible. The invention further discloses a method for performing punching on an H-shaped steel web. According to the method, the requirement for the field area and the surrounding environment is low, the punching efficiency of the punch is high, and labor force and cost are saved.
Description
technical field [0001] The invention relates to the technical field of assembling and manufacturing steel structural component products, in particular to a device and method for making holes on H-shaped steel. Background technique [0002] In the manufacture and installation of H-shaped steel structure workshops and frames, most of the connection methods between beams and columns, and between beams and beams are connected by high-strength bolts, which requires holes on the web or flange of H-shaped steel. At present, the method of making holes on the web or flange of H-shaped steel mainly adopts the method of drilling, and there are three main methods: 1) using a three-dimensional drilling machine, but the cost of this equipment is too high, and the volume of the equipment is relatively large, which is harmful to the site. The area and surrounding environment requirements are also high; 2) Imported hollow magnetic drills are used. Before drilling, the positioning line of eac...
