Abstract
A bending mould of U-shape workpiece relates to a large size bending mould and belongs to automatic mould industry technology field. The utility model comprises a die holder, a swing female die, a press plate, an air cushion, a push-off pin and a male die; wherein, the swing female die is movably connected with the die holder, the press plate is connected with the air cushion by the push-off pin and is movably connected with the die holder, and the male die is moving in the swing female die; the swing female die comprises two female die parts, each of which is connected with the die holder by an elastic ejector pin formed at the lower part thereof, and each of the two female die parts is providped with a rotating shaft; and an elastic detach pin is arranged in the lower part of the male die. Both the elastic ejector pin and the elastic detach pin are consisted of spring and pin. The utility model can reshape the workpiece into standard part, and has the advantages of simple structure, easy control, high efficiency and good quality.
Description
(1) technical field
The utility model relates to a kind of large-scale bending mould, belongs to automobile die industry technology field.
(2) background technology
Existing mould when punching press " U " type bool, rebound phenomenon usually occurs, has had a strong impact on the quality of stamping parts.Therefore, the technical staff is normal to adopt on the stamping parts structure, in the mould design or adopt other process to process to reduce resilience, but effect is undesirable; Because the stamping parts structure can not be changed often, and other processes are too complicated, if adopt said method in the mould design, then only are applicable to middle-size and small-size, for large-scale bool, because radius is bigger, cause its resilience also big, so inapplicable.
(3) summary of the invention
The utility model is for remedying the deficiencies in the prior art, provide a kind of simple in structure, easy to operate, efficient is high, matter measured " U " shape part bending die.
The utility model is finished by following technical measures.
This mould mainly is made up of die shoe, swinging cavity die, holding pad, air cushion, pressure pin and punch; wherein, swinging cavity die is movably connected on the die shoe, and holding pad is connected with air cushion by pressure pin; and be movably connected on the die shoe, the punch activity is between swinging cavity die.
Swinging cavity die is made up of two blocks of dies, and the elasticity ejector pin by its underpart is connected on the die shoe respectively, on two blocks of dies rotating shaft is installed respectively.
The elasticity ejector pin is made up of pin and spring.
In the punch bottom elasticity sprue puller pin is set.
The elasticity sprue puller pin is made up of spring and pin.
The utility model makes product be subjected to excessive compression to remedy the springback capacity after bending by swinging cavity die is set; In the punch bottom elasticity sprue puller pin is set, its effect is after punching press finishes product to be released; Use holding pad can when punching press begins, play the binder effect, finish the back in punching press and play the push piece effect.Its operation principle: when punch presses down product, force two swinging cavity dies inwardly to be pressed, product is pressed into
Shape, up when die shoe, the elasticity ejector pin opens swinging cavity die under the effect of rotating shaft to reset, the product resilience after the press-bending becomes " U " type, holding pad by the forcing press air cushion by pressure pin jack-up, the product on the punch then by the elasticity sprue puller pin releasing.Use the utility model can make product distortion back resilience become standard component, have advantages such as simple in structure, easy to operate, that efficient is high, quality is good.
(4) description of drawings
Accompanying drawing is the utility model structural representation.
Wherein: 1, die shoe; 2, rotating shaft; 3, swinging cavity die; 4, holding pad; 5, air cushion; 6, pressure pin; 7, elasticity sprue puller pin: 8, product; 9, guide plate, 10, punch, 11, the elasticity ejector pin, 12, back-up block.
(5) specific embodiment
Embodiment: structure is installed swinging cavity die 3 as shown in drawings on die shoe 1, swinging cavity die 3 is made up of two blocks of dies, is movably connected on the die shoe 1 by elasticity ejector pin 11 respectively, and the elasticity ejector pin is made up of pin and spring.On two blocks of dies rotating shaft is installed respectively, die is realized its rotating shaft 2 rotations by moving up and down of elasticity ejector pin 11; Holding pad 4 is connected with air cushion 5 by pressure pin 6, and is movably connected on the die shoe 1, is provided with elasticity sprue puller pin 7 in the punch bottom, and the elasticity sprue puller pin is made up of spring and pin, and punch activity 10 is between swinging cavity die 3.During use, product is located, when punch 10 bends bottom dead centre with blank, force two swinging cavity dies 3 inwardly to be pressed, product is pressed into by back-up block on the die shoe and guide plate
Shape, remedying the springback capacity after curved, up when die shoe 1, elasticity ejector pin 11 opens swinging cavity die 3 to reset, and product 8 resiliences after the press-bending become " U " type; By forcing press air cushion 5 and two pressure pins, 6 jack-up, the product on the punch 10 is then released the product after bending by elasticity sprue puller pin 7 by holding pad 4.
Claims (3)
1, a kind of " U " shape part bending mould; it is characterized in that; mainly form by die shoe, swinging cavity die, holding pad, air cushion, pressure pin, punch; wherein; swinging cavity die is movably connected on the die shoe; holding pad is connected with air cushion by pressure pin, and is movably connected on the die shoe, and the punch activity is between swinging cavity die.
2, a kind of " U " according to claim 1 shape part bending mould is characterized in that swinging cavity die is made up of two blocks of dies, and the elasticity ejector pin by its underpart is connected on the die shoe respectively, on two blocks of dies rotating shaft is installed respectively.
3, a kind of " U " according to claim 1 shape part bending mould is characterized in that, establishes by the elasticity sprue puller pin in the punch bottom.
