Embodiment Construction

[0007] like figure 1 As shown, it is a hydraulic punch, including a U-shaped frame 1, and the U-shaped frame 1 includes a first support block 1-1, a second support block 1-2, a base 1-3, a first support block 1-1, a first support block 1-1, a second support block 1-2, and a base 1-3. The two support blocks 1-2 are integrally arranged on both sides of the base 1-3 respectively. The inner side of the first support block 1-1 is provided with a lower mold 2, the second support block 1-2 is provided with a through hole 10, and the base 1-3 is provided with a through hole 10. The upper part is connected to the guide base 5 by bolts 11 , and a bronze sleeve 4 is arranged in the guide base 5 , and the through hole 10 , the bronze sleeve 4 and the lower die 2 are arranged coaxially. An oil cylinder 8 is arranged on the outside of the U-shaped frame 1. The oil cylinder 8 mainly includes a cylinder barrel 8-1, a piston 8-2, a piston rod 8-3, a guide sleeve 8-4, and one end of the cylinde...

Abstract

The invention provides a hydraulic puncher and relates to structures of punchers. The hydraulic puncher comprises a U-shaped frame. The U-shaped frame comprises a base, a first supporting block and a second supporting block. A lower die is arranged on the inner side of the first supporting block. A through hole is formed in the second supporting block. A guide seat is connected to the base. A bronze sleeve is arranged in the guide seat. The through hole, the bronze sleeve and the lower die are coaxially arranged. An oil cylinder is arranged on the outer side of the U-shaped frame and mainly comprises a cylinder barrel, a piston, a piston rod and a guide sleeve. One end of the cylinder barrel is connected with the U-shaped frame through a flange, one end of the guide sleeve is arranged in the cylinder barrel, the other end of the guide sleeve is arranged in the through hole, the end, penetrating out of the guide sleeve, of the piston rod is connected with a punch, and the punch penetrates the interior of the bronze sleeve. A workpiece to be punched is conveyed between the guide seat and the lower die and the piston rod of the oil cylinder extends out to punch the workpiece; due to the fact that one end of the guide sleeve extends into the through hole of the second supporting block, it is guaranteed that the piston rod stretches and retracts without deviation; and the guide seat and the bronze sleeve are used for guidance, so that the punch is free of deviation in the punching process, the position is accurate, efficiency is high, and labor is saved.

Description

technical field [0001] The invention relates to the structure of a hole punch, in particular to an anchor riveting (longer section steel) of a pre-embedded channel, and a device for punching holes on a long workpiece before riveting. Background technique [0002] The methods currently used: 1. Punch holes with a drilling machine; 2. Punch holes with a punching machine. The above two methods require drilling one by one, repositioning, clamping, and low efficiency. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a hydraulic hole puncher with no deviation in punching in order to overcome the deficiencies of the prior art. [0004] The purpose of the present invention is achieved in this way: the hydraulic hole punch includes a U-shaped frame, and the U-shaped frame includes a base, a first support block, and a second support block, and the first support block and the second support block are integrally arranged on the base On both sides,...
