Technical field
The present invention relates to a kind of aluminum profile extrusion equipment, be specifically related to a kind of automatic centering type stretcher jaw being applied on aluminium stretcher.
Background technology
In process of production, a lot of occasions need to be carried out stretch processing to aluminium, and stretching is to make the macromolecular chain in high polymer carry out orientations along outer force direction, thereby reaches a kind of method of improving Polymer Structure and mechanical property.The lower cutter tooth plate of tradition stretcher jaw is fixed, by driving upper slitter tooth plate to clamp aluminium section bar, the aluminium section bar that the various cross-sectional sizes that can stretch as required in process of production differ, the master cylinder center of so each aluminium section bar center line stretching and stretching-machine is not on same center line, in drawing process, can produce moment of flexure, especially large-tonnage stretching-machine often uses the service life of meeting reduction equipment, simultaneously to aluminium section bar due to not at center stressed, by making aluminium section bar, press the outer deformation process drawing in producing one, to service precision, there is the aluminium section bar of specific (special) requirements cannot meet the mechanical property of its requirement.Therefore aluminium section bar stretching-machine is optimized to and comprises moving guide rail, be positioned at the mobile stretching head on moving guide rail, pull the stretching-machine master cylinder that stretching head moves and be positioned at the clamping device on mobile stretching head, described clamping device comprises sliding block, thereby upper sliding block drives it toward the middle mobile aluminium that clamps from driving mechanism respectively, because top shoe is under the effect of self gravitation, the speed moving down, and sliding block speed is up slower, thereby cause the Clamping Center of sliding block toward moving down, with stretching-machine master cylinder not on same center line, section bar is easily out of shape, affect stretching quality.
Existing part manufacturer, in order to address the above problem, adopts computer control mode or hydraulic control system, adjusts the precision of its clamping, although which can address the above problem, its complex structure, cost are high, are unfavorable for promoting.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of automatic centering type stretcher jaw of rational in infrastructure, accurate positioning.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of automatic centering type stretcher jaw, be included as the stretching head main body of C font, be arranged in stretching head main body and for clamping aluminium, lower clamp, on, the both sides of lower clamp are respectively by upper, sliding block is arranged on, on lower clamp slide, on described, lower clamp interconnects by a link gear, described link gear and/or on, lower clamp is connected with driving mechanism, described link gear comprises the synchronising (connecting) rod that is positioned at stretching head main body middle, the cross contiguous block being connected with synchronising (connecting) rod, be hinged on respectively the upper of cross contiguous block both sides, lower connecting block, on described, the other end of lower connecting block is respectively with upper, sliding block is hinged.
In the present invention, the tail end of described synchronising (connecting) rod connects and is connected with driving mechanism, and described driving mechanism is a stretcher jaw oil cylinder, and the direction of motion of stretcher jaw oil cylinder is parallel to horizontal line.
In the present invention, described upper and lower slide block is connected with driving mechanism respectively, and described driving mechanism is upper and lower clamp oil cylinder, and the angle between upper and lower clamp oil cylinder is 60 °.
In the present invention, the middle part of described stretching head main body is provided with the through hole that synchronising (connecting) rod is installed, and is arranged with the copper sheathing that facilitates synchronising (connecting) rod to slide in through hole.
In the present invention, the angle of described upper and lower clamp slide is 60 °.
The invention has the beneficial effects as follows: when driving mechanism promotes upper and lower slide block, move and carry out holder while doing, upper and lower slide block links mutually by link gear, make its speed the same and arrive simultaneously, thereby realize the synchronous of upper and lower clamp, and after clamping, the center line of upper and lower clamp just in time with stretching-machine master cylinder on same center line, make section bar stressed more even, drawing effect is better.The present invention compares with traditional hydraulic system or digital control system, and the present invention adopts mechanical structure to carry out synchronous and centering, simple in structure, production cost is low, and centering is more accurate.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the present invention is further described:
Fig. 1 is the structural representation of embodiment mono-;
Fig. 2 is the structural representation of embodiment bis-.
The specific embodiment
Embodiment mono-, with reference to Fig. 1, a kind of automatic centering type stretcher jaw provided by the present invention, be included as C font stretching head main body 1, be arranged in stretching head main body 1 and for clamping the upper and lower clamp 21,22 of aluminium, because tensile force of the present invention is applicable to 100 ~ 300T, described stretching head main body 1 is spliced by the large plate in two of left and right; The both sides of upper and lower clamp 21,22 are arranged on upper and lower clamp slide 41,42 by upper and lower slide block 31,32 respectively, described upper and lower clamp 21,22 interconnects by a link gear, described link gear is connected with driving mechanism, described link gear comprise be positioned at stretching head main body 1 middle synchronising (connecting) rod 51, the cross contiguous block 52 being connected with synchronising (connecting) rod 51, be hinged on respectively the upper and lower contiguous block 53,54 of cross contiguous block 52 both sides, the other end of described upper and lower contiguous block 53,54 is hinged with upper and lower slide block 31,32 respectively.
