The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
By shown in Fig. 1 to Fig. 7, a kind of drift that metal circular tube tube wall is carried out to punching, include drift body 1, what described drift body 1 one end was provided with that punching wears metal circular tube tube wall goes out boss 101, the described cross section ovalize of going out boss 101, described drift body 1 other end is provided with and coordinates the auxiliary section 102 that promotes its punching with drive unit.By the metal circular tube of described drift punching, can be copper pipe, aluminum pipe etc.
Described auxiliary section 102 is for being located at the open slot of described drift body 1 lower end, and the opening direction of described open slot is vertical with the minor axis of the described elliptic cross-section of going out boss 101, and the bottom land of described open slot is the inclined-plane of inclination.
Described drift body 1 is with described to go out boss 101 one-body molded.Drift body 1 is with to go out boss 101 one-body molded, and processing and manufacturing is simple, and accuracy to size is high.
Described drift body 1 can also be gone out boss 101 moulding respectively with described, described goes out the upper end that boss 101 is fixedly connected on described drift body 1.Owing to going out boss 101 when going out metal circular tube tube wall, stressed large, wearing and tearing unavoidably, therefore, go out the material of boss 101 and should select High Strength Wear-Resistance Material, as carbide alloy in the course of time.Go out boss 101 and drift body 1 minute body formed, go out the material selection High Strength Wear-Resistance Material of boss 101, as carbide alloy, drift body 1 can be selected corresponding cheap material, can reduce costs like this, increases benefit.
A kind of hole punched device that metal circular tube tube wall is carried out to punching, comprise the drift that can fill in metal circular tube 4 pipes, described drift includes drift body 1, what described drift body 1 one end was provided with that punching wears metal circular tube 4 tube walls goes out boss 101, the described cross section ovalize of going out boss 101, described drift body 1 other end is provided with and coordinates the auxiliary section 102 that promotes its punching with drive unit 2, and described hole punched device also comprises for clamping the fixture 3 with the metal circular tube 4 at described drift opposite position place.
Described auxiliary section 102 is for being located at the open slot of described drift body 1 lower end, the opening direction of described open slot is vertical with the minor axis of the described elliptic cross-section of going out boss 101, the inclined-plane of the bottom land of described open slot for tilting, described drive unit 2 includes push rod 201, on described push rod 201, be arranged with the fixed sleeving 202 sliding for described push rod 201 within it, on the tube wall of described fixed sleeving 202, both sides offer through hole 202a relatively, described drift is arranged in described through hole 202a, in the process that described push rod 201 promotes forward on the inclined-plane along described, the described boss 101 of going out passes described through hole 202a and rushes metal circular tube 4 tube walls that are set on outside described fixed sleeving 202.Fixed sleeving 202 has played guide effect when push rod 201 moves forward and backward, the relative both sides of the tube wall of fixed sleeving 202 offer through hole 202a, drift is arranged in through hole 202a, when push rod 201 promotes forward drift body 1, drift can only slide up and down in through hole 202a, has prevented that the axis direction along fixed sleeving 202 pushes away away drift body 1 by push rod 201.
Operation principle:
As shown in Figure 8, first by fixed sleeving 202, drift and push rod 201 are positioned in the relevant position of fixture 3, then the metal circular tube 4 for the treatment of punching is set on fixed sleeving 202, and along C to promoting metal circular tube 4, move it the relevant position to needs, then drive push rod 201 to move forward in fixed sleeving 202, during punching, the inclined-plane of the open slot bottom land of the front end edge drift body 1 of push rod 2 promotes forward drift fast, because open slot bottom land is inclined-plane, so in the process promoting forward at push rod 201, drift body 1 in through hole 202a by jack-up, 101 of the boss of going out of drift body 1 upper end stretch out in through hole 202a, and punching is set on the tube wall of the metal circular tube 4 on fixed sleeving 202.Owing to going out the cross section of boss 101, be oval, and this oval-shaped minor axis is vertical with the axis direction of metal circular tube, so the end face of the flange forming on tube wall after punching is very concordant, the surrounding of the punching of going out is very smooth.Now completed the one-shot forming of punching.When needs are during in the next hole of tube wall upper punch, push rod 2 is drawn back, drift falls after rise in fixed sleeving 202, then move forward metal circular tube 4, when moving to next required punching position, again promote forward push rod 2, drift is by jack-up, go out 101 of boss and stretch out completely and rush poling wall in through hole 202a, thereby complete punching again.The metal circular tube of final punching moulding as shown in figure 10.
