Abstract
The utility model relates to a portable hydraulic grounding flat steel bender comprising a hydraulic grip movable mold, a hydraulic grip static mold, a dual-hole static mold and a mold blocking pin, wherein a V-shaped groove is arranged at the inner side of the hydraulic grip movable mold, the dual-hole static mold is welded at the front end of the hydraulic grip static mold, and the mold blocking pin is vertically inserted into two holes of the dual-hole static mold. Compared with the prior art, the portable hydraulic grounding flat steel bender has the advantages of being reasonable in structural design, attractive in appearance, and convenient to carry. Compared with the prior art, the portable hydraulic grounding flat steel bender has high yield, can save materials and has a better quality effected after being installed.
Description
Technical field
The utility model relates to a kind of portable hydraulic ground connection band steel bending machine.
Background technology
In the electrical equipment installation, wherein project under construction is to carry out laying of earth bus to transformer room and high and low voltage electric distribution are indoor, and the main material of use is the band steel of long 6m sectional area 40*4mm.
The ground connection band steel mainly is to rely on metope to carry out articulating, and for the positions such as corner of metope, band steel also changes the bending equal angular corresponding to metope and lays, and reaches corresponding impression quality requirement.Because not having corresponding on-the-spot specialized tool, conventional method mainly is to bend after heating with oxygen-acetylene at the scene, or has measured size and type shape earlier, uses bench vice to bend to machining location afterwards.Shortcoming is to cause the band steel performance change, and inefficiency is attractive in appearance and often make mistakes, and causes the waste of material.
Summary of the invention
The purpose of this utility model provides a kind of portable hydraulic ground connection band steel bending machine, its reasonable in design, safety easy to use, and good looking appearance is easy to carry.
For achieving the above object, the utility model is realized by the following technical solutions:
Portable hydraulic ground connection band steel bending machine, comprise hydraulic tongs dynamic model, the quiet mould of hydraulic tongs, the quiet mould of diplopore, mould backing pin, described hydraulic tongs dynamic model inboard is provided with V-butt, and the quiet mould front end of hydraulic tongs is welded with the quiet mould of diplopore, and the mould backing pin vertically inserts in two holes of the quiet mould of diplopore.
Compared with prior art, the utility model has the advantages that:
Simple in structure, need not power supply, size is less, is easy to carry, and is easy to use, and the process of bending is to finish in base inside, guaranteed workmen's safety.Because of its drift part less, band steel can crooked size less, that shape is complicated.Band steel organoleptic quality after the processing is good, and existing relatively technology is compared the yield rate height, economical with materials, and mass effect is better after installing.

The specific embodiment
Be described in detail the specific embodiment of the present utility model below in conjunction with accompanying drawing.
See figure, Fig. 2, the hydraulic tongs transformation of the way that this device parent adopts electrical installation project to use forms, hydraulic tongs 1 its strength size as parent plays decisive role, adopting pressure is the hydraulic tongs of 5-8T, through measuring and calculating, can satisfy the requirement of bending rate in the work progress, thereby to adopt it be power source.
Determining and selection of bending rate this time set the V-arrangement free bend mode that adopts.The rate of curving

In order to adapt to this work, the head of hydraulic tongs is transformed, and kept its original function.Weld two thick iron plates of 8m as the quiet mould 4 of diplopore at quiet mould 5 front ends of hydraulic tongs, and bore two parallel holes, and process two T8 structural section φ 16 steel die backing pins 3 as the cover half fulcrum in its axial vertical direction.Because the quiet mould 5 front opening 35mm of hydraulic tongs less than the band steel width, respectively go to interface two inboards the 3mm developed width to reach 41mm and guarantee the 1mm gap for this reason.Because its die stroke is 20mm, the utility model prolongs the dynamic model size again, and making the distance between dynamic model static position and the φ 16 mould shelves pins 3 is 5mm, and the dynamic model inboard is ground forming V-shape groove 2, thereby addresses this problem.
When the bending band steel, concrete construction method is that the band steel that needs are converted into certain angle is put between the V-butt 6 and two φ 16 mould shelves pins 3 of hydraulic tongs dynamic model 2, band steel needs bending point to aim at hydraulic tongs dynamic model 2 tops, and the work of primer fluid pressing tongs is till being converted into the angle that needs.
