The steel pipe punching die of band activity-oriented die body of the present invention, the mode of punching is adopted to replace Drilling operation, during punching punch safety do not rupture, steel pipe section circularity in claimed range, die body is indeformable, the line of centres of Kong Yukong gone out meets linearity requirement vertically, can realize quick, high efficiency punching processing.
Specific embodiment:
According to different outer diameter of steel pipes, wall thickness and punching position, aperture, determine outside dimension, changement size and track and base dimensions in die body length, diameter, concave-convex mold size, punch guiding shell.
As shown in Figure 1 and Figure 2, comprising:
(1) Punches structure:
This part structure is with guide housings 14 for central link part, and die body 8 is connected on guide housings 14 by guide pillar 9 and guide pin bushing; Die body 8 height and position is determined by die body shop bolt 11 and the reset rubber spring 12 be enclosed within guide pillar 9; Die 15 is embedded on die body 8; Die body 8 head is workpiece guide frame, and afterbody is counterweight 7; Balance rubber spring 20 is arranged at counterweight 7 top; Guide housings 14 side is provided with Workpiece fixing pin 6; Punch 13 is connected with stamping machine slide block (not shown) by upper bolster, and is led by guide housings 14 in punch process and protect; Whole mold is fixed on stamping machine workbench by die shoe 2.
(2) workpiece charging and changement structure (alternate configurations):
This part structure mainly comprises workpiece commutation dolly 3 and two trolley tracks 4, and the dolly 3 that wherein commutates comprises the compositions such as tray for work pieces 18, gyroaxis and bearing 16, bearing block 17, roller 19; Article two, the both sides of trolley track 4 are provided with two reinforcements, and are connected by die shoe 2.
(3) course of work describes:
1. die debugging located and be fixed on stamping machine workbench;
2. will be positioned on the tray for work pieces 18 of workpiece commutation dolly 3 in the middle part of workpiece 5;
3. promote workpiece 5 and workpiece commutation dolly 3, workpiece 5 one end to be pushed in punching die guide housings 14 and to withstand Workpiece fixing pin 6;
4. start stamping machine slider switch, stamping machine slide block falls and promotes punch 13 and works, and when punch 13 contacts workpiece 5, forcing press is contact equilibrium rubber spring 20 simultaneously;
5. punch 13 presses down workpiece 5, makes workpiece 5 that elastic deformation occur; Meanwhile, balance rubber spring 20 and workpiece 5 are depressed bottom die body 8 to workpiece 5, now, and the equal engagement concavity die body in workpiece 5 top and bottom;
6. punch 13 continues to decline, and workpiece 5, under punch 13 and die 15 are sheared, completes punching;
7., after machine slide block to be punched resets, pull workpiece 5 and workpiece commutation dolly 3, workpiece 5 punching end is drawn to outside guide housings 14;
If 8. do not need punching, then take off workpiece; If need opposite side punching, then turning of work piece pallet 18 and workpiece 5 commutate, and perform step 9.;
9. repeat 3. to arrive 7. process, complete the punching of the workpiece other end.
The steel pipe punching die of the band activity-oriented die body in above-described embodiment, die and die body can move up and down along guide pillar, adapt to when steel pipe inserts the requirement of die gap width and the needs of different wall (to be generally less than 10mm) within the specific limits; Move up and down the fatigue rupture fracture that die and die body fundamentally avoid die body; Guide housings has the structure of guide effect simultaneously to punch and workpiece; Die body head possesses guide function to workpiece; Afterbody balancing spring plays balanced action when punching press to guide pillar side force; Die body be directed to two vertical axis of guides, thus avoid the rotation of die body in horizontal plane, two vertical axis of guides all adopt lubricant method; The vertical axis of guide of die body is equipped with back-moving spring, in the natural equilibrium position of the recessed die body of action of reset spring be: the axes coincide in workpiece (steel pipe) hole of die body axis and punching die, when punching, die body is pressed down, punching completes and after drift is carried, die body sets back under the effect of back-moving spring; Commutation car top has tray for work pieces, to the structure of the maintenance effect of workpiece; Be furnished with roller outside dolly, facilitate the structure that workpiece forward and back material and workpiece turn around.
In above-described embodiment, workpiece feeding manner, workpiece turn around to be manually, and electric rotating machine and linear electric motors also can be adopted to replace above-mentioned workpiece changement; Punches structure and workpiece charging and changement structure two parts all can be used as independently mechanism.
Adopt punching die structure of the present invention and workpiece changement, use steel pipe punching technology, greatly can promote the working (machining) efficiency of this type of workpiece hole, reduction in the numbers of seconds.
The above; be only the present invention's preferably detailed description of the invention, but protection scope of the present invention is not limited thereto, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; the change that can expect easily or replacement, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claims.
