Description
Technical field
The utility model relates to bench apparatus field, specifically a kind of large-tonnage bench stretching dolly automatic decoupling device.
Background technology
In aluminum pipe preparation process, bench is one of shaping important process equipment of aluminum pipe.The tradition bench course of work is roughly: clamped by the stretching head of aluminum pipe one end by the stretching clamping clip on the stretching dolly on bench, main hook simultaneously on stretching dolly is hooked on main chain drum shaft, under the effect of main chain trombone slide power, the direction motion of stretching dolly chain linked to owner bar running, starts drawn aluminum tube simultaneously; After aluminum pipe stretches, because the main hook on stretching dolly is not subject to the effect of trombone slide power again, under the double action that back-moving spring B on main chain self gravitation and stretching dolly drives top to reset, the main hook of stretching dolly generally can automatically and chain drum axle depart from.
Due to reasons such as main hook deadweight are comparatively large, reseting torque is less, above-mentioned unhook mode is in actual production process, especially the deadweight of large-tonnage bench main hook is quite large, often occur that aluminum pipe pulls the phenomenon that after-drawing dolly main hook does not take off hook, potential safety hazard is brought to equipment, add the amount of labour of operating personnel, seriously hinder production efficiency.
Summary of the invention
In order to solve the problem, the utility model provides a kind of and is adapted to large-tonnage bench, stretching dolly automatic decoupling device that unhook efficiency is high.
Concrete scheme of the present utility model is: a kind of large-tonnage bench stretching dolly automatic decoupling device, there is base, the side of base is slidably fitted with the inner connector for hollow, one end of connector is set with vertical shaft, the other end is equipped with tripping gear, the lower hinge of vertical shaft has stretching clamping clip, between stretching clamping clip and connector, back-moving spring A is also housed, it is characterized in that: described tripping gear comprises connecting plate, connecting rod, main hook, top, dwang, lance and fork, one end of connecting plate is hinged on vertical shaft upper end, the other end and rod hinge connection, connecting rod is also hinged on the main hook neck of hook by column, the end of the main hook neck of hook is inner at connector by hinge, the upper end of described top is arc, and be arranged between connecting plate and connector, the lower end of top is connected with one end of drive link, and the other end of drive link is sleeved on the upper end of fork, and described lance is arranged on position corresponding with fork on base by support member retractable, also be provided with back-moving spring B below described base, one end of back-moving spring B is connected to bottom fork, and the other end is connected to the position near vertical shaft below base.
One end that drive link described in the utility model is connected with top is sleeved in gripper shoe, and gripper shoe is welded on connector, and described fork is wedge structure.
Base bottom described in the utility model is one in front and one in back symmetrically installed with roller.
Compare traditional stretching dolly tripping gear, the advantage that the utility model possesses is:
1. adopt fork, top, connecting plate Multi-stage transmission mode, back-moving spring B is exaggerated several times to the opplied moment of lifting that main hook breaks off relations, adapt to and meet large-tonnage bench main hook unhook reliable and stable requirement;
2. structure ingenious, connect compact, transmission efficiency is high, solve aluminum pipe and to have stretched the phenomenon that after-drawing dolly main hook cannot break off relations often.

Detailed description of the invention
In the present embodiment, a kind of large-tonnage bench stretching dolly automatic decoupling device, there is base 1, one in front and one in back be symmetrically installed with four rolling 2 below base 1, the side above base 1 is provided with the connector 3 of hollow, and connector 3 can along slide anteroposterior on base 1, one end of connector 3 is set with vertical shaft 4, the other end is equipped with tripping gear, and the bottom axle of vertical shaft 4 is connected with stretching clamping clip 5, between stretching clamping clip 5 and connector 3, back-moving spring A6 is also housed.
In the present embodiment, tripping gear comprises connecting plate 7, connecting rod 8, main hook 9, top 10, dwang 11, lance 12 and fork 13, one end of connecting plate 7 is hinged on vertical shaft 4 upper end, the other end is hinged on connecting rod 8, connecting rod 8 is also hinged on main hook 9 neck of hook by column 13, and the end of main hook 9 neck of hook is inner at connector 3 by hinge; In tripping gear, one end of drive link 11 is one in front and one in back set with two gripper shoe A14, and be fixedly connected with connector 3 by gripper shoe A14, the middle part that drive link 11 is positioned at two gripper shoe A14 is welded with the lower end of top 10, the upper end of top 10 is arcwall face, the other end of drive link 11 is sleeved on the upper end of fork 13, fork 13 is wedge structure, and can freely swing around drive link 11; Described lance 12 is sleeved in right two the support member B15 of a first from left, and be fixedly mounted on base 1 by support member B15, lance 12 two support member B15 determine along left and right rectilinear direction can make stretching motion back and forth, and this direction of motion is just in time consistent with the side surface direction of fork 13; In addition, be also provided with back-moving spring B16 below base 1, one end of back-moving spring B16 is connected to bottom fork 13, and the other end is connected to the position near vertical shaft 4 below base 1.
The course of work of the present utility model can be divided into preparation, trombone slide, unhook, return four-stage:
Preproduction phase: in this stage, stretching dolly is in the preparation in early stage of aluminum pipe stretching operation, now, back-moving spring A6 is natural shrinking state, stretching clamping clip 5 jaw opens, and back-moving spring B16 is natural shrinking state simultaneously, fork 13 VE, the peak coming directly towards 10 upper end arcwall faces plays main support effect to connecting plate 7, and main hook 9 upwards lifts;
The trombone slide stage: start main chain transmission, stretch stretching dolly rollback to aluminum pipe section start, lance 12 is subject to the shock of template prescription steel column simultaneously, promote fork 13 to rotate around drive link 11, back-moving spring B16 is opened in stretching, and by drive link 11, top 10 is driven to rotate, the comparatively low spot of top 10 arcwall face is made to act on connecting plate 7, by connecting plate 7, the transmission of connecting rod 8, main hook 9 is caused to fall, and be fastened on main chain drum shaft, meanwhile, back-moving spring A6 is stretching open configuration, stretching clamping clip 5 jaw clamping aluminum pipe, at this moment drawn aluminum tube is started, now, owing to there is huge trombone slide power between main chain and main hook 9, the main chain being positioned at engaging place can be lifted by main hook 9, it is protruding that this place can present " people " font,
In the unhook stage: after an aluminum pipe has stretched, main hook 9 loses huge trombone slide power, and under the effect of main chain self gravitation and back-moving spring B16 convergent force, main hook 9 just can rapidly from reliable and stable unhook main chain drum shaft;
The return stage: again by stretching dolly rollback to original position, each unit status is consistent with the preproduction phase.
