Description
Technical field
The present invention relates to the automatic material clamping mechanism of a kind of angle bender, particularly a kind of angle bender.
Background technology
The general reinforcing bar that uses, as concrete skeleton, to improve concrete intensity, is called stirrup by the reinforcing bar that plays skeleton function traditionally at present, the reinforcing bar of a cylindricality is converted into the shape such as polygon, circle, formed stirrup, the two ends of stirrup link together, and can keep original intensity.
When reinforcing bar carries out bending on angle bender, need to be fixed its position.On some angle bender, there is clamping device now, but these clamping device complex structures, production cost is high; and in actual production process; to the insufficient clamping force of reinforcing bar, reinforcing bar usually can be subjected to displacement in Forging Process, will have influence on like this size after reinforcing bar bending.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides the automatic material clamping mechanism that a kind of simple in structure, clamping force is large, reinforcing bar can not be subjected to displacement the angle bender of phenomenon in Forging Process.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of automatic material clamping mechanism of angle bender, comprise frame, apparatus for bending and tooth bar pushing disc are installed in frame, described apparatus for bending comprises bearing, described bearing hollow, slide-bar is installed on bearing and match with slide-bar for preventing the fixed block of reinforcing bar perk, on the periphery of described tooth bar pushing disc, be provided with projection piece, on described bearing, being provided with can be by the propulsion arm of projection piece jack-up, the inner chamber of bearing is stretched in the upper end of described propulsion arm, on propulsion arm, be set with the Compress Spring that can make propulsion arm reset, on propulsion arm, be connected with connecting rod, connecting rod is fixedly connected with the movable block that can coordinate to clamp with fixed block reinforcing bar away from one end of propulsion arm, bearing is provided with opening below fixed block, movable block is positioned at opening part and is hinged on bearing by bearing pin, described connecting rod is positioned at the inner chamber of bearing.
In the present invention, the lower end of described propulsion arm is provided with the projection that can accept Compress Spring, and described Compress Spring is between bearing and projection.
In the present invention, in described bearing, be provided with the brace table for accepting connecting rod.
In the present invention, described connecting rod comprises the first connecting rod and the second connecting rod that are fixed together, and described first connecting rod is connected with propulsion arm, and described second connecting rod is connected with movable block.
The invention has the beneficial effects as follows: reinforcing bar is in the time of bending, and movable block coordinates clamping reinforcing bar with fixed block; After bending completes, the projection on tooth bar pushing disc turns to the below of propulsion arm and upwards promotes propulsion arm, and propulsion arm drives movable block to rotate, and movable block unclamps the reinforcing bar of bending, and reinforcing bar falls down automatically.Then the reinforcing bar for the treatment of bending drops on slide-bar, and along with the rotation of tooth bar pushing disc, projection leaves propulsion arm, propulsion arm resets under the effect of Compress Spring, propulsion arm drives movable block to rotate reset simultaneously, and the elastic force of Compress Spring makes movable block again clamp reinforcing bar, repeats above process.The present invention can automatically clamp reinforcing bar and unclamp, and clamping force is large, and reinforcing bar can not be subjected to displacement phenomenon in Forging Process, can greatly enhance productivity.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further detailed explanation.
Fig. 1 is the structural representation of a direction of the present invention;
Fig. 2 is the structural representation of other direction of the present invention;
Fig. 3 is the partial enlarged drawing at A place in Fig. 1.
The specific embodiment
As shown in Fig. 1 ~ Fig. 3, a kind of automatic material clamping mechanism of angle bender, comprise frame 1, apparatus for bending 2 and tooth bar pushing disc 20 are installed in frame 1, described apparatus for bending 2 comprises bearing 21, described bearing 21 hollows, slide-bar 3 is installed on bearing 21 and match with slide-bar 3 for preventing the fixed block 4 of reinforcing bar perk, on the periphery of described tooth bar pushing disc 20, be provided with projection piece 5, on described bearing 21, being provided with can be by the propulsion arm 6 of projection piece 5 jack-up; The inner chamber of bearing 21 is stretched in the upper end of described propulsion arm 6, on propulsion arm 6, be set with the Compress Spring 7 that can make propulsion arm 6 reset, as preferably, the lower end of described propulsion arm 6 is provided with the projection 61 that can accept Compress Spring 7, and described Compress Spring 7 is between bearing 21 and projection 61.When rotated, projection piece 5 is and then rotation together also for tooth bar pushing disc 20, after projection piece 5 turns to and contact with propulsion arm 6, can upwards boost propulsion arm 6, and projection 61 can push Compress Springs 7 simultaneously, makes Compress Spring 7 that strain occur.Along with the rotation of tooth bar pushing disc 20, projection piece 5 separates with propulsion arm 6 again, and propulsion arm 6 can fall under the elastic force effect of Compress Spring 7.
On propulsion arm 6, be connected with connecting rod 8, connecting rod 8 is fixedly connected with the movable block 9 that can coordinate to clamp with fixed block 4 reinforcing bar away from one end of propulsion arm 6, bearing 21 is provided with opening 22 below fixed block 4, movable block 9 is positioned at opening 22 places and is hinged on bearing 21 by bearing pin 91, and described connecting rod 8 is positioned at the inner chamber of bearing 21.As preferably, in described bearing 21, be provided with the brace table 23 for accepting connecting rod 8, described connecting rod 8 comprises the first connecting rod 81 and the second connecting rod 82 that are fixed together, and described first connecting rod 81 is connected with propulsion arm 6, and described second connecting rod 82 is connected with movable block 9.When propulsion arm 6 moves upward, movable block 9 away from one end of second connecting rod 82 from fixed block 4 more and more away from, the reinforcing bar that has completed bending is released, and now the slide-bar 3 of spacer bar is also retracted, and the reinforcing bar that has then completed bending can fall down from the apparatus for bending of angle bender.
Reinforcing bar is in the time of bending, and movable block 9 coordinates clamping reinforcing bar with fixed block 4; After bending completes, the projection piece 5 on tooth bar pushing disc 20 turns to the below of propulsion arm 6 and upwards promotes propulsion arm 6, and propulsion arm 6 drives movable block 9 to rotate, and movable block 9 unclamps the reinforcing bar of bending, and reinforcing bar falls down automatically; Then the reinforcing bar for the treatment of bending drops on slide-bar 3, along with the rotation of tooth bar pushing disc 20, projection piece 5 leaves propulsion arm 6, propulsion arm 6 resets under the effect of Compress Spring 7, propulsion arm 6 drives movable block 9 to rotate reset simultaneously, the elastic force of Compress Spring 7 makes movable block 9 again clamp reinforcing bar, repeats above process.The present invention can automatically clamp reinforcing bar and unclamp, and clamping force is large, and reinforcing bar can not be subjected to displacement phenomenon in Forging Process, can greatly enhance productivity.
The above, be preferred embodiments of the present invention, but the present invention is not limited to above-described embodiment, as long as it reaches technique effect of the present invention with any same or similar means, within all should falling into protection scope of the present invention.
