Description

A kind of bar bending die tool
Technical field
The present invention relates to a kind of mould, be specifically related to a kind of bar bending die tool.
Background technology
In production process, usually need bar is carried out to bending, usually use bending machine to carry out bending work, when but to ask for something, higher bar carries out bending, such as bar being processed into to U-shaped that bending angle is had relatively high expectations, common bending machine does not reach the standard that requires usually, and efficiency is also lower.
Summary of the invention
Goal of the invention: purpose of the present invention just is to provide a kind of bar bending die tool.
Technical scheme:For achieving the above object, the present invention has taked following technical scheme:
A kind of bar bending die tool, it is characterized in that: comprise die frame, described die frame middle part is provided with mold cavity, described mold cavity top is provided with punch, described punch top is provided with die shank, described mold cavity both sides are provided with bending mechanism, described bending mechanism comprises fixation clip, die and adjusting bracket, described adjusting bracket is located at described mold cavity both sides, described die is located between described adjusting bracket and described mold cavity, described fixation clip is located at described adjusting bracket top, wherein the adjusting bracket horizontal direction of a side also is connected with screw bolt and nut, knee, both sides, described mold cavity bottom is provided with swinging cavity die, be provided with holding pad between described swinging cavity die, described holding pad is located at described mold cavity bottom, described mold cavity bottom also is provided with drawbar, described drawbar is located between described holding pad, described swinging cavity die corner is provided with cushion block, bottom is provided with spring, described cushion block is stuck between described swinging cavity die and die frame.The present invention in use, bar can be pressed into to the U-shaped of particular requirement by punch, die and holding pad, and then the effect by swinging cavity die is close on punch bar to be pressed into U-shaped, after moulding, workpiece and punch break away from, release from mold cavity under the effect of spring and holding pad, so just obtain U-shaped an of moulding.
Described spring the inside is provided with ejector pin.
Described fixation clip top also is provided with bolt.
Described bending mechanism is replaceable.
Beneficial effect:Adopt the present invention of technique scheme to have the following advantages:
The present invention is simple to operate, not only can carry out bending to bar and can also carry out shaping to bar by swinging cavity die, makes bar can disposablely be processed into the workpiece that plasticity is higher, high efficiency; Bending mechanism in the present invention is removable, can have good versatility by changing bending mechanism to meet the demand of different workpieces processing like this, of many uses.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure: 1-pressure pin, 2-cushion block, 3-swinging axle, 4-swinging cavity die, 5-holding pad, 6-adjusting bracket, 7-punch, 8-die shank, 9-die, 10-screw rod, 11-fixation clip, 12-mold cavity, 13-nut, 14-bolt, 15-ejector pin, 16-spring, 17-die frame.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further set forth.
As shown in the figure: a kind of bar bending die tool of the present invention, it is characterized in that: comprise die frame 17, described die frame 17 middle parts are provided with mold cavity 12, described mold cavity 12 tops are provided with punch 7, described punch 7 tops are provided with die shank 8, described mold cavity 12 both sides are provided with bending mechanism, described bending mechanism comprises fixation clip 11, die 9 and adjusting bracket 6, described adjusting bracket 6 is located at described mold cavity 12 both sides, described die 9 is located between described adjusting bracket 6 and described mold cavity 12, described fixation clip 11 is located at described adjusting bracket 6 tops, wherein adjusting bracket 6 horizontal directions of a side also are connected with bolt 14 and nut 13, described mold cavity 12 knees, both sides, bottom are provided with swinging cavity die 4, be provided with holding pad 5 between described swinging cavity die 4, described holding pad 5 is located at described mold cavity 12 bottoms, described mold cavity 12 bottoms also are provided with drawbar 1, described drawbar 1 is located between described holding pad 5, described swinging cavity die 4 corners are provided with cushion block 2, bottom is provided with spring 16, described cushion block 2 is stuck between described swinging cavity die 4 and die frame 17, described spring 16 the insides are provided with ejector pin 15, described fixation clip 11 tops are provided with screw rod 10.
Implementation process of the present invention is as follows:
While by the present invention, bar being carried out to bending, the present invention and forcing press support the use, bar to be bent is placed on die 9, the starting pressure machine, under the effect of power, punch 7, die 9 and holding pad 5 actings in conjunction, make bar to be bent press as U-shaped, when bar is depressed into dead point, under the effect of swinging cavity die 4 interior pressures, make bar be close on punch 7, be pressed into U-shaped, swinging cavity die 4 has played the shaping operation to bar work in this process, bar is pressed as after the U-shaped part, under the effect of the ejector pin 15 of spring 16 the insides, make swinging cavity die 4 reset, holding pad 5 now can bending is good U-shaped part ejection die die cavity 12, thereby completed crooked this operation of bar.Can complete efficiently the crooked work of the bar of having relatively high expectations by the present invention, improve greatly production efficiency.
