Description

Portable busbar shaper

technical field

The utility model belongs to the technical field of electric power engineering equipment, in particular to a portable busbar shaper used for busbar cutting, shaping and punching on-site busbars in various electric power projects and power distribution projects of industrial and mining enterprises.

Background technique

At present, busbars are mostly installed in switchboards (boxes). With the economic development and the increase of customer electricity consumption, the capacity of distribution transformers continues to increase. The rated current of the original switchboard switch and the allowable carrying capacity of the busbar cannot meet the existing requirements, and the switch needs to be replaced. And the busbar (the original wiring hole does not correspond after the switch is replaced, the aluminum row is replaced with the copper row, etc.). During the on-site construction, the construction personnel mostly use manual work for the interception, punching, and bending of the busbar. The construction process is not beautiful, the labor intensity is high, and there are certain difficulties and unsafe factors.  

Contents of the invention

The purpose of the utility model is to overcome the above disadvantages and provide a portable busbar shaper for cutting, shaping and punching the busbar. The utility model utilizes the hydraulic crimping pliers of the existing equipment to produce a special mold, which retains the original crimping function and adds the functions of cutting, punching and bending small busbars. And the volume is small and easy to carry, and it is fast and convenient to use on site. The technical solution adopted to realize the purpose of the utility model is: a portable bus bar shaper, including a hydraulic clamp 1, and the hydraulic clamp 1 is provided with a handle 2, a hydraulic handle 3 and The pliers head 4 is characterized in that: the pliers head 4 is provided with an upper mold groove 5 and a lower mold groove 6, and an upper shear mold 7 and a lower shear mold 8 are formed in cooperation with the upper mold groove 5 and the lower mold groove 6. The shear die, the bending die composed of the upper bending die 9 and the lower bending die 10, the punching die composed of the upper punching die 11 and the lower punching die 12, and the upper crimping die 13 and the lower crimping die 14 crimping die. The upper punching die 11 and the lower punching die 12 are respectively provided with an upper rubber pad 15 and a lower rubber pad 16 opposite to each other. The utility model utilizes hydraulic pliers to provide power, can cut, shape and punch the bus bar, and realize the cutting and shaping of the bus bar. The shearing mold can cut the busbar within the range according to the size of the mold, and can also cut some aluminum strands, steel core aluminum strands, steel strands, round steel with a diameter of less than 16mm, etc. The bending mold can bend some copper bars, aluminum bars, flat steel and other rectangular materials within 90 degrees according to the angle requirements, and can perform arc chamfering to reduce the indentation on the busbar during bending. A rubber pad is added to the punch of the punching die to facilitate the ejection of the punch in the workpiece. The upper punching die is assembled to facilitate the production of discharge space, and can punch holes with a diameter of less than 13mm. And the mold installation and replacement is quick and convenient.

The portable busbar shaper of the utility model is small in size, convenient to carry, simple to operate, fast and convenient to replace molds, safe and reliable, and convenient for on-site construction. Full function can realize cutting, punching, bending and other processing and shaping functions for small busbars. It is more convenient to use, safer, and the construction process is more beautiful, greatly reducing the labor intensity and time of the staff, improving work efficiency, avoiding unsafe factors such as on-site manual production, and overcoming the unsightly construction process and high labor intensity in the past. Certain difficulties and other shortcomings. And it does not affect the use of the original crimping pliers.
