Description

A transition plate manual hydraulic punching machine

technical field

The utility model relates to a manual hydraulic punching machine for a transition plate, in particular, it is suitable for processing long holes for connecting aluminum plates connected with electrical equipment.

Background technique

In the construction, technical transformation and overhaul of 220kV substation new stations, electrical equipment connection transition boards need to be used in large quantities. At present, the construction tools equipped by operators are inefficient, labor-intensive, and unable to guarantee quality when performing drilling, slot milling and other processing techniques. However, it is impossible to punch long holes with existing punching machines, and the parts to be punched will often be stuck on the punch head. The technology and process cannot meet the standards, and equipment manufacturers have no corresponding accessories to provide. Without a corresponding mold, the long hole cannot be impacted, resulting in material waste and low production efficiency.

Contents of the invention

The technical problem to be solved by the utility model is to provide a kind of equipment, which can not only realize the cutting function of the aluminum plate, but also realize the punching of the long hole, avoid the stuck parts to be punched on the punch, improve the efficiency, ensure the product quality and reduce the labor intensity. In order to solve the above problems, a hydraulic punching machine for transition plates is provided.

The purpose of this utility model is achieved in the following manner:

The utility model is mainly composed of an upper template, a lower template and two sets of guide assemblies symmetrically distributed between the upper and lower templates. The guide assembly includes a column fixed between the upper beam and the lower template and a guide sleeve fixed on the upper template. , characterized in that: a return spring is connected between the upper template and the lower template; Punching and shearing tool; above the lower template is connected with a punching and shearing tool corresponding device through positioning pins; the punching and shearing tool is a single-edged cutter and a punch. The corresponding devices of the punching and shearing tool are a fixed knife and a stripper. The upper template is provided with a drop cap. The lower template is provided with a die corresponding to the punch. The lower template is set on the base.

Compared with the prior art, the utility model has the following beneficial effects: 1. The punching and shearing tool is equipped with a punch and a single-edged cutter. During work, the single-edged cutter and the fixed knife are first used to cut the aluminum plate into the desired shape. Replace the single-edged cutter with a punch, remove the fixed knife and the blanking positioning plate, and fix the stripping plate to complete the required shape of the workpiece. One device serves two purposes. 2. There is a return spring outside the column on one side, which can make the upper formwork return to its original shape without pressure. 3. There is a drop cap on the upper template, which can adjust the stroke of the punch from the die and the elastic force of the return spring. 4. An unloading plate is added between the punch and the positioning plate. After the punching is completed, the unloading plate can keep the parts to be punched on the positioning table, preventing the parts to be punched from being stuck on the punch. 5. The thrust of the hydraulic piston of the jack is used during use, which saves time and labor compared with manual operation, and can ensure product quality, improve production efficiency, and reduce labor intensity.

Detailed ways

As shown in the drawings, the utility model is mainly composed of an upper formwork 4, a lower formwork 6, and two sets of guide assemblies symmetrically distributed between the upper and lower formworks. The column 3 and the guide sleeve 5 fixed on the upper template 4, a return spring 12 is connected between the upper template 4 and the lower template 6; the return spring 12 is attached to the column 3 on one side; the upper template 4 and the upper beam 2 are fixed There is a jack 8; a punching and shearing tool 9 is fixed below the upper template 4; a punching and shearing tool corresponding device 13 is connected above the lower template 6 through a positioning pin 10; the punching and shearing tool 9 is a single-edged cutter and a punching tool. head. The punching and shearing tool corresponding device 13 is a fixed knife and a stripper. The upper template 2 is provided with a drop cap 1 . The lower template 6 is provided with a die 11 . The lower template 6 is set on the base 7 .

The utility model device is placed on the ground, the punch is replaced with a single-edged cutter, the stripping plate is replaced with a fixed knife, and a blanking positioning plate is installed. Put the 2mm aluminum plate on the fixed knife as required, and set the size with reference to the blanking positioning plate. Open the check valve of the jack, and the hydraulic piston of the jack pushes the upper template to move downward to cut the aluminum plate. After cutting the aluminum plate into the desired shape, replace the single-edged cutter with a punch, remove the fixed knife and the blanking positioning plate, and fix the stripping plate. Place the cut aluminum plate between the stripper plate and the lower template 6, open the jack check valve 14, and use the thrust of the hydraulic piston of the jack to generate a downward pressure on the upper template, driving the punch to impact the thickness of the aluminum plate 2mm round hole. After finishing the punching process, loosen the check valve of the jack, under the action of the return spring, the upper platen moves up, the parts to be punched are blocked by the stripper plate, and the punch separates from the parts to be punched and rises to the original position.
