Abstract
The utility model relates to the technical field of press machines, in particular to a slotting type compensation structure of a workbench of a bending machine. The slotting type compensation structure of the workbench comprises the workbench, and opened grooves which penetrate through the width direction of the workbench are arranged at two ends of the lower side of the workbench in the length direction of the workbench respectively. By adoption of the slotting type compensation structure of the workbench, the opened grooves are arranged at two ends of the lower side of the workbench, a sliding block drives a mold to bend downwards, the opened grooves of the two sides of the workbench enable the two sides of the workbench to downwards produce certain elastic deformation so as to compensate for deformation of the workbench, and therefore deflection deformation produced by bending of a workpiece is eliminated and precision of the size of the bending workpiece is improved. Structural design and concept are simple, a special compensation part does not need to be additionally arranged, the whole structure of the workbench is simplified, and installation and maintenance of the slotting type compensation structure of the workbench are convenient.
Description
Technical field
The utility model relates to the press technologies field, particularly the workbench open flume type collocation structure of bender.
Background technology
In the bender of prior art, as shown in Figure 1, workbench 1 is owing to the reason of installation accuracy and machine self rigidity, the bending non-uniform phenomenon appears in workpiece bending part easily, and the two ends bending degree of depth is big, middle part bending depth as shallow, make by bending part deflection deformation to occur, influence the bending precision of workpiece.For addressing this problem, need the rigidity and the intensity of strengthening device self on the one hand; On the other hand, adopt of the distortion of deformation-compensated method with compensation work platform self.At present, mainly contain two kinds of compensation methodes, a kind of is as shown in Figure 2, on workbench 1 surface mechanical compensation cushion block 2 is set, with the distortion of compensation work platform 1 self.But this compensation method can only be rough compensated part distortion, compensation precision is poor, but also needs to install in addition the compensation cushion block.Also has a kind of compensation method as shown in Figure 3, be that the distortion of compensation cylinder 3 with compensation work platform 1 is set in workbench 1, in this kind compensation way, the installation dimension of cylinder is subjected to the restriction of bed dimension, the installation of compensation cylinder 1 is also cumbersome, and two to three cylinders generally can only be set, compensation adjustment point is less, compensates inhomogeneous.
The utility model content
The utility model is at the problem that prior art exists, provide a kind of simple in structure, be used for the workbench open flume type collocation structure of bender reliably, uneven problem is out of shape in two ends and middle bending during with the work of compensation bender.
Order of the present utility model is achieved in that a kind of workbench open flume type collocation structure, comprises workbench, and described workbench downside two ends are respectively equipped with the open slot that runs through the workbench width along the length direction of workbench.
Adopt otch formula collocation structure of the present utility model, open slot is arranged on the two ends of workbench downside, when slide block drive mould carries out the bending action downwards, the open slot of both sides makes the work top both sides produce certain elastic deformation downwards, distortion in order to the compensation work platform, thereby eliminate the deflection deformation that the workpiece bending produces, improve the dimensional accuracy of bending part.This structural design design is simple, and special compensating unit need not be set in addition, has simplified the overall structure of workbench, is convenient to the installation and maintenance maintenance of equipment.
For ease of resetting behind the workbench elasticity bending, described open slot is downward-sloping to the centre from two ends along the length direction of workbench.
Be the further distortion of fine compensation workbench, the length of described open slot is 1/4～1/3 of workbench length.
Description of drawings
Schematic diagram when Fig. 1 produces distortion for the bender workbench.
Fig. 2 is the schematic diagram of available technology adopting compensation cushion block compensation work platform distortion.
Fig. 3 is the schematic diagram of available technology adopting compensation cylinder compensation work platform distortion.
Fig. 4 is a workbench open flume type collocation structure schematic diagram of the present invention.
Wherein, 1 workbench; 2 compensation cushion blocks; 3 compensation cylinders; 4 open slots.
The specific embodiment
Be illustrated in figure 4 as workbench open flume type collocation structure of the present utility model, comprise workbench 1, workbench 1 downside two ends are respectively equipped with the open slot 4 that runs through workbench 1 width along the length direction of workbench 1; Open slot 4 is downward-sloping to the centre from two ends along the length direction of workbench 1; And the length of open slot is 1/4～1/3 of workbench length.
Adopt otch formula collocation structure of the present utility model, open slot 4 is arranged on the two ends of workbench 1 downside, when slide block drive mould carries out the bending action downwards, the open slot 4 of both sides makes the work top both sides produce certain elastic deformation downwards, distortion in order to compensation work platform 1, thereby eliminate the deflection deformation that the workpiece bending produces, improve the dimensional accuracy of bending part.This structural design design is simple, and special compensating unit need not be set in addition, has simplified the overall structure of workbench 1, is convenient to the installation and maintenance maintenance of equipment.
The utility model is not limited to the foregoing description; every on the basis of the disclosed technical scheme of the utility model; those skilled in the art is according to disclosed technology contents; do not need performing creative labour just can make some replacements and distortion to some technical characterictics wherein, these replacements and distortion are all in the scope of the utility model protection.
Claims (3)
1. a workbench open flume type collocation structure comprises workbench, it is characterized in that, described workbench downside two ends are respectively equipped with the open slot that runs through the workbench width along the length direction of workbench.
