Description
Technical field
The invention belongs to the die apparatus field, particularly relate to the column punching die that a kind of satellite antenna is used.
Background technology
At present, satellite antenna comprises antenna and bearing, and antenna is connected with bearing by column, need to regulate the elevation angle while due to antenna, installing, therefore on the hole wall at the two ends of column, both sides all need two installing holes of punching press respectively, in order to meet the needs that antenna is fixing and aerial angle is regulated, but the column punching die of prior art once can only two installing holes of punching press one stomidium wall one side, therefore need two secondary diels, to the both sides of a stomidium wall respectively punching press once just can complete punching, this has just increased the use cost of mould, and the punching cycle is also longer; While is because elevation angle adjusting need to be higher to the required precision between two installing holes, and by after twice punching of two width moulds, front one-off hole-piercing can cause the Leading Edge Deformation of column, cause the alignment precision in two-sided hole low and be difficult to control, and then affect positioning precision and make the precision of installing hole of last moulding lower, be unfavorable for follow-up installation, increased the difficulty of installing, make when regulating " elevation angle " " azimuth " also along with change after installation, and then cause antenna adjustments more difficult, can't normally receive signal and can't use.
Summary of the invention
The present invention is directed to above problem provides a kind of and can once rush the whole installing holes of end, and the punching cycle is shorter, and the precision of installing hole is higher and install after regulate and be easy to the column punching die.
the present invention overcomes the above problems technical scheme used: a kind of column punching die is provided, it comprises counterdie and patrix, described patrix and counterdie are slidably connected, described counterdie comprises die holder, described die holder is provided with chute, the one side inwall at described chute middle part is provided with opening, the opposite side inwall at chute middle part is provided with the columniform die head for the socket column, radially be provided with two through holes on described die head, and the axis of through hole is parallel with chute, in described chute, the both sides of die head slidably connect respectively slide block, be equipped with on described two slide blocks and two through holes drift one to one, on described die head two through holes under be equipped with blanking port, described blanking port is communicated with each self-corresponding through hole, described patrix comprises fixed head, described fixed head is provided with and promotes the pressure head that two slide blocks slide to the die head direction, be provided with resetting-mechanism between described slide block and chute.
after adopting above device, compared with prior art, the present invention is owing to being provided with two drifts, and drift is two installing holes of punching press simultaneously once, during punching press, drift impacts to the die head place simultaneously, make on the hole wall of column one end and can once stamp out simultaneously four installing holes, after an end punching of column is completed, the other end of column also is inserted in the die head punching to be got final product, because be punching simultaneously, can effectively prevent the problem of bringing the column distortion of two times punch, make the precision of four installing holes of column one end higher, make yield rate higher, be convenient to follow-up fitting operation, and again due to only with a secondary mould, reduced production cost.Therefore the present invention has and can once rush the whole installing holes of end, and the punching cycle is shorter, and the precision of installing hole is higher and install after regulate the characteristics of being easy to.
As improvement, four angles of described fixed head are provided with slide opening, described die holder be provided with slide opening one to one and the guide pillar that is slidably connected with slide opening, be equipped with linear bearing between described slide opening and guide pillar, after linear bearing arranges, frictional force between slide opening and guide pillar reduces, and then the energy consumption while reducing mold work, reduces the use cost of mould.
As further improvement, described slide block is provided with inclined-plane away from an end of die head, the lower end of described pressure head is provided with the inclined-plane that matches with the slide block inclined-plane, to paste inclined-plane be that mechanism's parts of motion of horizontal direction are less with the conversion of motion of vertical direction for this inclined-plane, structure is simpler, and be that simple frame for movement stability in use is better, service life is also longer.
as further improving again, described resetting-mechanism comprises guide rod, limited block and back-moving spring, described limited block is separately fixed on the outer face at chute two ends, and limited block is provided with the center stepped hole, macropore in the stepped hole of described center is positioned on position away from chute, one end of described guide rod is fixedly connected with each self-corresponding slide block, the sidewall at described chute two ends is provided with for guide rod and passes guide hole, the other end of described guide rod is crossed corresponding guide hole and center stepped hole separately successively, described back-moving spring is arranged in the macropore of center stepped hole, and back-moving spring is socketed in the other end of guide rod, the other end end of described guide rod is provided with the spacing banking stop in the stepped hole macropore of center of back-moving spring, the resetting-mechanism parts of this structure are less, simple in structure, preparation cost is lower, for simple mechanical mechanism stability in use better, service life is also longer, also be convenient to simultaneously the maintenance in later stage, reduce maintenance cost, and guide rod also plays the effect to slider guide, makes slide block slide in the process of sliding more stable, makes the stability of drift punching press better, and then guarantees the punching precision of installing hole.
as further improving again, be provided with the guide pad for drift in described chute, described guide pad is positioned at position corresponding to chute opening, described guide pad middle part is provided with groove, the cross section of described groove consists of with two parallel straight flanges the base of half arc, between the diameter on the base of described half arc and two parallel straight flanges, spacing is equal to the diameter of column, the axis of described half base arcuate edge and the dead in line of die head, the two side of described groove is equipped with for the pilot hole to the drift guiding, the width of described guide pad is greater than the width of chute, after guide pad arranges, stability while making the drift punching press is better, and drift is not prone to situation about breaking yet, and then improve the precision of installing hole and the service life of mould, the guide pad of this structure does not need fixed mechanism simultaneously, and this has just saved expense and the installing space thereof of fixed mechanism, and then reduces die cost and reduce the mould floor space.
as further improving, the outer surface of described chute opening part is provided with pin, the length direction of described pin is parallel with the axis of die head, one end of described pin is fixed on the outer surface of opening part, the other end of pin is provided with square baffle plate, the plane of described baffle plate equals the radius of column to the vertical range between die head axis extended line, after the arranging of lever and baffle plate, make the workman when inserting column, only need column is inserted and gets final product against baffle plate from opening part, need again need not the workman to bend over to aim at, and then raising workman's operating efficiency, and reduction workman's labour intensity.
