Description
Technical field
It the utility model is related to construction equipment manufacture field, and in particular to a kind of angle-bender.
Background technology
In building field, in order to improve the building intensity of building itself, usually reinforcing bar is used in combination with concrete, but by
Different in the form of building itself, reinforcing bar needs to be cut, shaped a series for the treatment of process such as bending, ability before shaping
Meet the needs of construction.Commonly used angle-bender can need to realize to the different journeys of reinforcing bar according to architectural design with construction
The bend fixing operation of degree.
Existing conventional numerical control Double-head angle-bender, as shown in figure 1, its structure is set movably on track 21
Bending machine main body 22, a bending position-limited rack 23 is set in bending machine main body 22, is centered around the outside setting of bending position-limited rack 23
One C-shaped groove 24, and set in the C-shaped groove 24 to be driven by drive mechanism and rotate and flexible bend arm 25, will during work
The correct position that two bending machine main bodys 22 are moved on track, reinforcing bar is treated into dogleg section frame on bending position-limited rack 23,
Then reinforcing bar is firmly clamped by the geometrical clamp 26 of pneumatic control with being arranged between two bending machine main bodys 22, bend arm 25 stretches out
And rotated in the C-shaped arc range of C-shaped groove 24 around bending position-limited rack 23, bend arm 25 turns over one relative to horizontal direction
Determine angle, a part for reinforcing bar is bent into default angle relative to horizontal direction around bending position-limited rack 23, reaches bending
The purpose of shaping.In the process, the scope of activities of bend arm 25 is the C-shaped arc range that C-shaped groove 24 is recessed.
Angle probe typically is internally provided with angle-bender, is engaged with the numerical control program of angle-bender, to examine
Lateral bending is cranked arm relative to the angle that turns over of bending position-limited rack and carries out the control of rotational angle to it, realizes the difference of formed reinforcing steel bars
It is molded specification.For angle-bender, once internal numerical control programming parameter selection is improper or angle probe breaks down
Deng easily causing the angle that actually turns over of bend arm to exceed the angular range that is limited of C-shaped groove both ends so that bend arm is dashed forward
C-shaped groove both ends position is so collided until being stopped by gear, these failures not only result in bend arm, C-shaped groove two-end part
Put and produce mechanical collision damage, the more serious motor for also resulting in driving bend arm rotation causes electricity instantaneously by stall
Machine immediate current is substantially increased and burns out motor, it is necessary to which angle-bender manufacturer to motor repair or even changes motor
Complete machine, its maintenance cost is very high, maintenance cycle is also grown, and often produces considerable influence to Construction Schedule, causes to be constructed into
This rising.
In addition, existing angle-bender, during moment reinforcement, reinforcing bar is also easy to stick into C-shaped groove, causes steel
Muscle brake forming angle is forbidden, or the relative position off-design requirement of reinforcing bar two bent portion, causes product qualified
Rate reduces, and influences yield rate and production efficiency, improves product cost.
The content of the invention
