Abstract
The invention discloses a rotating flip type no-indention mold. The rotating flip type no-indention mold comprise a left rotating flip, a right rotating flip, a lower mold body, a baffle and tension springs, wherein two symmetric arc grooves are formed in the top of the lower mold body; the left rotating flip and the right rotating flip are respectively mounted in the two arc grooves and are positioned on the same plane; the baffle is fixed on the lower mold body; the left rotating flip, the right rotating flip and the lower mold body are respectively limited and fixed through the tension springs; the upper ends of the tension springs are connected with the left rotating flip and the right rotating flip; and the lower ends of the tension springs are connected with the baffle. In a process of pressing a workpiece in the lower mold body by using an upper mold, because the workpiece is in contact with the planes of the rotating flips, the rotating flips rotate in the lower mold body, in a whole bending process of the workpiece, the rotating flips cannot slide relatively, indention and scratching which are generated due to the fact that the surface of the workpiece is extruded are eliminated, and appearance quality and precision of the workpiece are improved effectively. The rotating flip type no-indention mold is simple in structure and long in service life, and the economic benefit is increased.
Description
Technical field
The present invention relates to a kind of bending lower die device, specifically a kind of turnover plate type that rotates is without pressing die, belongs to accurate without impression bending lower die technical field.
Background technology
At present, Bending Mould is die apparatus conventional in sheet metal product machine-shaping, development along with industries such as engineering machinery, automobile, track traffic, boats and ships, Aero-Space, electrical instrumentation and building decorations, domestic and international panel beating enterprise to the forming accuracy of sheet metal product, presentation quality, shape complexity requirement more and more higher, to the accuracy of manufacture and the service life of Bending Mould it is also proposed that higher requirement.The counterdie of tradition bending generally has openings of sizes to differ the V-shaped groove for bending different-thickness sheet material.When using it for bending, under the effect of bending power, sheet material moves along counterdie V-arrangement notch edges and is subject to the extruding of bending power, easily make that the sheet metal part surface after shaping forms obvious impression and pull defect, the width of imperfect tape is about 0.414 times of V-shaped groove mouth, has had a strong impact on the presentation quality of product.And, counterdie be also result in abrasion by the frictional force formed between movement and counterdie V-shaped groove and the sheet material of sheet material in Forging Process, decreases its service life.Therefore one can solve drawbacks described above occur in tradition bending, can overcome the movement of sheet material in Forging Process and counterdie V-shaped groove is current developing direction to the mould of the frictional force that sheet material is formed.
Summary of the invention
For above-mentioned prior art Problems existing, the present invention provides a kind of turnover plate type that rotates without pressing die, its simple in construction, and long service life can improve the presentation quality of sheet metal product, increase economic efficiency.
To achieve these goals, the one that the present invention adopts rotates turnover plate type without pressing die, and including the dynamic turnover panel that turns left, turn right dynamic turnover panel, lower mold body, baffle plate and extension spring, described lower mold body top has two symmetrical arc grooves；Turn left to move turnover panel, dynamic turnover panel of turning right is separately mounted in two arc grooves, and in the same plane；Described baffle plate is fixed in lower mold body；Turn left to move turnover panel, turn right to move and fix respectively through extension spring is spacing between turnover panel and lower mold body；Extension spring upper end is connected with the dynamic turnover panel that turns left, dynamic turnover panel of turning right, and extension spring lower end is connected with baffle plate.
Preferably, described extension spring upper end is connected with the dynamic turnover panel that turns left, dynamic turnover panel of turning right by upper attachment screw, and extension spring lower end is connected with baffle plate by lower attachment screw.
Preferably, described baffle plate is fixed in lower mold body by fixing screw.
Compared with prior art, the present invention adopts the lower mold body opening two Symmetrical Circular Arc grooves, and installs left-right rotation turnover panel in arc groove, and adopts extension spring spacing fixing between left-right rotation turnover panel and lower mold body.At upper mould, workpiece is pressed in the process of lower mold body, due to workpiece and rotation turnover panel plane contact, rotate turnover panel to rotate in lower mold body, workpiece does not produce relative sliding with rotation turnover panel in whole Forging Process, eliminate impression and scratch that surface of the work produces owing to being squeezed, be effectively increased presentation quality and the precision of workpiece, its simple in construction, long service life, improves economic benefit.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figures 1 to 4, a kind of turnover plate type that rotates is without pressing die, and including the dynamic turnover panel 1 that turns left, turn right dynamic turnover panel 2, lower mold body 3, baffle plate 4 and extension spring 7, described lower mold body 3 top has two symmetrical arc grooves；Turn left to move turnover panel 1, dynamic turnover panel 2 of turning right is separately mounted in two arc grooves, and in the same plane；Described baffle plate 4 is fixed in lower mold body 3；Turn left to move turnover panel 1, turn right to move and fix respectively through extension spring 7 is spacing between turnover panel 2 and lower mold body 3；Extension spring 7 upper end is connected with the dynamic turnover panel 1 that turns left, dynamic turnover panel 2 of turning right, and extension spring 7 lower end is connected with baffle plate 4.
During installation, appropriate lubricating oil can be injected in arc groove and the dynamic turnover panel 1 of left-hand rotation is installed, turns right and move turnover panel 2.As shown in Figure 5 and Figure 6, when adopting above-mentioned bending lower die that sheet metal 9 is carried out Bending Processing, sheet metal 9 in whole Forging Process only with the plane contact of left-right rotation turnover panel 1,2, left-right rotation turnover panel 1,2 can rotate in the arc groove of lower mold body 3, sheet metal 9 and left and right turnover panel 1,2 plane do not produce relative sliding, thus eliminating impression and the scratch that surface of the work produces owing to being squeezed, it is effectively increased presentation quality and the precision of workpiece.When Bending Processing terminates, left and right turnover panel 1,2 is resetted by the effect of extension spring 7, makes the working face of left and right turnover panel 1,2 return to same plane, it is simple to the use of next time.Wherein, left-right rotation turnover panel can adopt high-quality mould steel to make, and has the characteristic of high accuracy, high intensity, further increases precision and the service life of mould.Left-right rotation turnover panel overall dimensions and centre distance can also design according to workpiece sheet metal thickness, are suitable for the accurate bending requirement of different-thickness sheet material.
