Abstract
The utility model discloses a safety bending device comprising a support mechanism, a jack, a V-shaped female die and a V-shaped male die. The V-shaped female and male dies match with each other. The support mechanism comprises a base, a support arranged on the base, and a beam arranged above the support. The male die is fixedly connected with the beam. The female die is fixedly connected with the jack fixed in the support. The female die is provided with pinholes. During bending metals, the female die is fixed on the support though pins and the pinholes. When the safety bending device is applied to bending hard metals such as copper bars, the female die is more stable; damage of the jack by acting force from bending can be effectively avoided.
Description
Technical field
The utility model belongs to power transmission and transformation field, relates in particular to a kind of for by the safe apparatus for bending of copper bar grade conducting heavy current product bending.
Background technology
In the power transmission and transformation field of power system, because high voltage line current is larger, there is the current conduction product application that resistivity is low, can bending degree large very extensive, therefore in power transmission and transformation line erection process, owing to being subject to the restriction of line discharge distance, need to carry out bending so that wiring to conducting heavy current products such as copper bar, aluminium row, band steel, round steel.Mostly normal bending equipment is curved row's machine of fluid pressure type at present, this kind of curved row's machine of fluid pressure type is motor machine, its topmost defect is to use power supply, because the scene of setting up of power transmission and transformation line mostly is spacious place, have an area of in one or two kilometers and do not have power supply available, power supply is inconvenient to obtain, for construction brings much inconvenience, not only lose time obtaining on power supply, and greatly reduce operating efficiency.And the curved row's body of fluid pressure type is long-pending larger, weight is heavier, is difficult for carrying; In addition, easily there is leakage of oil grade phenomenon in curved row's machine of fluid pressure type, and maintenance cost is higher.
In order to address the above problem, following patented technology is proposed in prior art:
As China Patent No. " 201020628441.3 " discloses a kind of Manual busbar bender, its open day is on July 20th, 2011, its technical scheme is that described curved row's machine comprises supporting mechanism, lifting body and mould, described supporting mechanism comprises base, is positioned at the support on base and is positioned at the crossbeam of support top, described lifting body is jack, the formpiston that described mould comprises former and matches with former.But due to former be movably arranged on jack in support above, the active force producing in the time of bending is larger, this active force is transferred on jack by former, not only easily make former depart from its installation site, also easily make damage of jack, the serious security incident that also can cause, its security is low.
Summary of the invention
The purpose of this utility model is to solve the problems referred to above that in prior art, Manual busbar bender exists, a kind of safe apparatus for bending is provided, adopt after the utility model, when to hard metal bendings such as copper bars, the stability of former is better, and the active force producing can effectively avoid bending time damages jack.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of safe apparatus for bending, it is characterized in that: the V-shape former and the formpiston that comprise supporting mechanism, jack and work in coordination, described supporting mechanism comprises base, is positioned at the support on base and is positioned at the crossbeam of support top, described formpiston is fixedly connected with crossbeam, described former is fixedly connected with the jack being fixed in support, on described former, be provided with pin-and-hole, during to metal folding, described former is fixed on support by bearing pin and pin-and-hole.
On described support, be provided with some fixing holes, during to metal folding, former passes pin-and-hole by bearing pin and is connected with fixing hole.
Employing the utility model has the advantage of:
One, in the utility model, in the time of bending, former is fixed on support by bearing pin, connect into an entirety with whole supporting mechanism, the active force that its bending produces is distributed to whole supporting mechanism, neither can make former be subjected to displacement, also can avoid because jack top is because of stressed excessive damage, compared with the prior art that is representative with the patent No. " 201020628441.3 ", the utility model has improved the security of apparatus for bending effectively, has reduced the probability of security incident.
Two, in the utility model, on described support, be provided with some fixing holes, during to metal folding, bearing pin passes from the fixing hole of support one side, be connected with the fixing hole on support opposite side through former again, not only simple in structure, with low cost, be easy to realize, also have the better advantage of former fixed effect.

Fig. 1 is main TV structure schematic diagram of the present utility model.
In figure, be labeled as: 1, base, 2, support, 3, jack, 4, former, 5, formpiston, 6, handle, 7, crossbeam, 8, pin-and-hole, 9, bearing pin, 10, fixing hole.
Detailed description of the invention
A kind of safe apparatus for bending, comprise supporting mechanism, jack 3 and the V-shape former 4 of working in coordination and formpiston 5, described supporting mechanism comprises base 1, is positioned at the support 2 on base 1 and is positioned at the crossbeam 7 of support 2 tops, described formpiston 5 is fixedly connected with crossbeam 7, described former 4 is fixedly connected with the jack 3 being fixed in support 2, on described former 4, be provided with pin-and-hole 8, during to metal folding, described former 4 is fixed on support 2 by bearing pin 9 and pin-and-hole 8.
Preferred embodiment of the present utility model is, is provided with some fixing holes 10 on described support 2, and during to metal folding, former 4 is connected with fixing hole 10 through pin-and-hole 8 by bearing pin 9, but is not limited to above-mentioned preferred embodiment.
Another preferred embodiment of the present utility model is that the top of described crossbeam 7 is provided with is convenient to portable handle 6.
Operation principle of the present utility model is: when work; first former 4 is fixed on to the top of jack 3; again the conducting heavy current products such as the required copper bar bending are placed between formpiston 5 and former 4; manual operation jack 3; upwards promote former 4; in the time that former 4 compresses the conducting heavy current products such as copper bar; bearing pin 9 is first passed to the fixing hole 10 of support 2 one sides; be connected with the fixing hole 10 of support 2 opposite sides through the pin-and-hole 8 on former 4 again; can stably copper bar be bent into needed angle, can effectively protect jack 3 to preserve from.
