Portable hydraulic multipurpose punching machine

Abstract

The invention discloses a portable hydraulic multipurpose punching machine. The problems that in the prior art, machines cannot be carried, and manual positioning is difficult are solved. The portable hydraulic multipurpose punching machine is characterized in that a rack is composed of a base (18), an oil cylinder seat (33), stand columns (34), nuts (12), handles (30) and handle mounting blocks (31); a hydraulic system is composed of a bottom cover (1), an oil cylinder (2), O-shaped sealing rings (4,6 and 10), a piston (8), a piston through connection shaft (20), a male connector (25) and a female connector (29), the piston through connection shaft (20) is connected with a male die seat (5) of a punching device, a female die seat (7) is arranged on the base (18) of the rack, die seat stand columns (9) are arranged at the oblique diagonals of the female die seat (7), stand column sleeve pipes (3) are arranged at the corresponding angular positions of the male die seat (5) of the punching device, a male die set (16) is arranged below the male die seat (5), and a female die set (17) is correspondingly arranged above the female die seat (7). The portable hydraulic multipurpose punching machine has the advantages of being reasonable in structure, easy to manufacture, convenient to carry and efficient, saving labor and the like, correspondingly dies are replaced according to different products, and the portable hydraulic multipurpose punching machine can be widely applied to electric system field construction sites for terminal connector punching.

Description

1. Technical field [0001] The invention belongs to electric machinery processing facilities, and in particular relates to a portable hydraulic multipurpose punching machine which is convenient for construction on field sites. 2. Background technology [0002] At present, the high-voltage primary equipment in the domestic power system is connected by steel-cored aluminum stranded wire or aluminum row and copper row. Connection, the workpiece that needs to be drilled generally has a thickness of 8-20mm, 2-4 holes, and the diameter of the hole is generally 12-20mm. At present, the steps we adopt for drilling equipment wire connection clamps or copper bars and aluminum bars are: 1. Manually mark the processed parts according to the size and quantity of the openings of the high-voltage equipment wiring board, and punch holes for positioning; 2. Use a single eye Hydraulic punching machine or drilling machine, hand electric drill select a punch or drill with a suitable diameter, a...

Problems solved by technology

Existing problems: First, due to the general multi-hole and different hole diameter processing, it is time-consuming and laborious to manually mark the positioning; second, even if the marking is accurate, during the processing process, due to the manual operation of hydraulic punching machines or electric drills are single holes Punching and drilling are prone to deviations, resulting in low precision of processed parts, partial holes during installation, prone to scrapped products and the need for secondary processing and calibration; the third is the punch of the existing hydraulic single-eye punching machine on the market The maximum stroke is: 12mm, and the thickness of the equipment clamps above SY-300 is more than 15mm, which cannot be punched at the work site and can only be processed by drilling machine or hand electric drill; Fourth, when using hydraulic single-eye punching machine processing due to Equipment wire clips are generally pure aluminum or pure copper parts. During processing, due to the single-point action of the punch on the surface of the wire clip, the wire clip will produce obvious deformation, which will affect the flatness of the contact between the wire clip and the equipment terminal board, and cannot For secondary calibration processing, only conductive paste can be filled, which is easy to leave hidden dangers of heating at the equipment joints
