Description
Technical field
The utility model relates to all kinds of engineering machinery, like the technical field of cab structures such as excavator, loading machine, relates in particular to the device that shape tube is carried out bending forming.
Background technology
Along with the generally use of shape tube in engineering machinery driving cabin, the integrally bending shaping to shape tube becomes the new threshold that it is promoted the use of.
Because cross section structure, section thickness and the material of shape tube is different; And the difference of the deflection of bending forming; All can cause the inequality of shape tube shaping bending springback rate; The raw-material each item index of domestic in addition shape tube can't accomplish that each batch is in full accord, thereby causes being shaped the more bad control of resilience.Particularly the most frequently used multistage changes the circular arc shape tube in the engineering machinery driving cabin, and the resilience change in size that its integrally bending is shaped can't be passed through data computation especially.
Summary of the invention
The purpose of the utility model is in order to overcome the deficiency of prior art, a kind of convenient and practical, low-cost, reusable, adjustable size is provided, can controls the shape tube integrally bending building mortion of resilience.
The purpose of the utility model is achieved in that shape tube integrally bending building mortion; Comprise workbench, the outside of workbench connects three cylinder brackets, connects first hydraulic jack on first cylinder bracket; Connect second hydraulic jack on second cylinder bracket; Connect the 3rd hydraulic jack on the 3rd cylinder bracket, second hydraulic jack is arranged between first hydraulic jack and the 3rd hydraulic jack, and the flexible end of first hydraulic jack, second hydraulic jack and the 3rd hydraulic jack is respectively towards workbench; The flexible end of second hydraulic jack connects limited block; The opposite side of limited block is provided with locating piece, and locating piece is connected on the workbench, and locating piece is provided with arc groove towards a side of limited block; Be respectively provided to few five flexible adjusting devices between said first hydraulic jack and second hydraulic jack and between second hydraulic jack and the 3rd hydraulic jack, each flexible adjusting device is connected on the workbench.
Adding man-hour, is example with C3 series shape tube that driver's cabin is adopted, and this shape tube is made up of the circular arc of three sections different sizes, leading portion circular arc R 1, drift angle circular arc R 2, back segment circular arc R 3.At first by general bending machine bending forming drift angle circular arc R 2; Flexible adjusting device in the utility model is adjusted to required size; The shape tube behind the preliminary bending forming is put on this novel overall bending apparatus, the middle hydraulic jack application of force is fixed the R angle that has been shaped again; The hydraulic jack application of force at two ends then, the leading portion circular arc R 1 with shape tube bends to correspondingly-sized with back segment circular arc R 3 respectively.Because the material of shape tube cross section and shape tube is different, the rebound degree of shape tube is also inequality, can regulate the flexible springback compensation setting position size of shape tube according to actual resilience, reaches final required crooked size.
The beneficial effect of the utility model is: change under the situation of the whole special section tubular product of radian irregular resilience that can effectively control shape tube at the crooked different size specification of need multistage.Regulate easily and switch to corresponding dimensions.The utility model can be widely used in the production in enormous quantities that plurality of specifications shape tube integrally bending is shaped, and is practical, exploitativeness is strong.
Improvement as the utility model; Each flexible adjusting device comprises holder respectively; Laterally place a screw rod in each holder respectively; Two nuts on two nuts that are threaded respectively on the every screw rod, every screw rod are separately positioned on the both sides of corresponding holder, and an end of every screw rod connects the cross section limited block respectively.The scalable screw rod is to required size, and fixed by two nuts on the screw rod.For different shape tube cross sections, only need to change corresponding cross section limited block and get final product easy switching.

The specific embodiment
As shown in Figure 1, shape tube integrally bending building mortion comprises workbench 1; The outside of workbench 1 connects three cylinder brackets 2, connects on first cylinder bracket 2 and connects second hydraulic jack 8 on 3, the second cylinder brackets 2 of first hydraulic jack; Connect the 3rd hydraulic jack 9 on the 3rd cylinder bracket 2; Second hydraulic jack 8 is arranged between first hydraulic jack 3 and the 3rd hydraulic jack 9, and the flexible end of first hydraulic jack 3, second hydraulic jack 8 and the 3rd hydraulic jack 9 connects limited block 7 towards the flexible end of workbench 1, the second hydraulic jack 8 respectively; The opposite side of limited block 7 is provided with locating piece 6; Locating piece 3 is connected on the workbench 1, and locating piece 6 is provided with arc groove 10 towards a side of limited block 7, and is as shown in Figure 3.Six flexible adjusting devices 5 are set between first hydraulic jack 3 and second hydraulic jack 8, five flexible adjusting devices 5 are set between second hydraulic jack 8 and the 3rd hydraulic jack 9, each flexible adjusting device 5 is connected on the workbench 1.
As shown in Figure 2; Each flexible adjusting device 5 comprises holder 5-1 respectively; Each holder 5-1 is connected on the workbench 1 through bolt respectively, laterally places a screw rod 5-3 in each holder 5-1 respectively, and two nut 5-2 are threaded respectively on the every screw rod 5-3; Two nut 5-2 on every screw rod 5-3 are separately positioned on the both sides of corresponding holder 5-1, and the end of every screw rod 5-3 connects cross section limited block 5-4 respectively.
Add man-hour, at first in General Pipe Bender, shape tube 4 is bent the drift angle circular arc, on workbench 1; Flexible adjusting device 5 is adjusted to needed size positions; The shape tube 4 of preliminarily forming is placed in the integrally bending former, the circular arc correspondence of preliminarily forming in the deep-slotted chip breaker 10 of locating piece 6, is started second hydraulic jack 8; Limited block 7 stretches out; Shape tube 4 parcels are spacing between locating piece 6 and limited block 7, start first hydraulic jack 3 and the 3rd hydraulic jack 9 this moment, promote the shape tube bending forming.When shape tube 4 bending springbacks or other reasons cause undersize, regulate flexible adjusting device 5, just can adjust the position of cross section limited block 5-4, accomplish springback compensation, bending forming again finally reaches the size of institute's actual demand.
