Description

Column punching die

Technical field

The invention belongs to field of die equipment, particularly relate to a kind of column punching die of satellite antenna.

Background technology

At present, satellite antenna comprises antenna and bearing, and antenna is connected with bearing by column, owing to needing to regulate the elevation angle during astronomical cycle, therefore both sides all need punching press two installing holes respectively on the hole wall at the two ends of column, to meet the needs that antenna is fixed and aerial angle regulates, but the column punching die of prior art once can only two, hole wall side, punching press one end installing hole, therefore need two secondary diels, to the both sides of one end hole wall respectively punching press once just can complete punching, this adds increased mold use cost, the punching cycle is also longer; Needs simultaneously due to elevation angle adjustment are 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 finally shaping installing hole lower, be unfavorable for follow-up installation, add the difficulty of installation, make after installation adjustment " elevation angle " while " azimuth " also along with change, and then cause antenna adjustments more difficult, cannot normal received signal and cannot using.

Summary of the invention

The present invention is directed to above problem provides one once can rush the whole installing hole in one end, and the punching cycle is shorter, and the precision of installing hole is higher and regulate easy column punching die after installing.

The present invention overcomes the above problems technical scheme used: provide a kind of column punching die, it comprises counterdie and patrix, described patrix and counterdie are slidably connected, described counterdie comprises die holder, described die holder is provided with chute, side inwall in the middle part of described chute is provided with opening, opposite side inwall in the middle part of chute is provided with the columniform die head for being socketed column, on described die head, radial direction is provided with two through holes, and the axis of through hole is parallel with chute, in described chute, the both sides of die head slidably connect slide block respectively, two described slide blocks are equipped with and two through holes drift one to one, described die head is equipped with blanking port immediately below two through holes, described blanking port is communicated with each self-corresponding through hole, described patrix comprises fixed head, described fixed head is provided with the pressure head that promotion two slide blocks slide to die head direction, resetting-mechanism is provided with 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 can once simultaneously punching press two installing holes, during punching press, drift impacts to die head place simultaneously, make the hole wall of column one end once can stamp out four installing holes simultaneously, after one end punching of column completes, the other end of column is also inserted in die head punching, because be punching simultaneously, then effectively can prevent the problem bringing column to be out of shape of two times punch, make the precision of four of column one end installing holes higher, make yield rate higher, be convenient to follow-up installation operation, and again owing to only using a secondary mould, reduce production cost.Therefore the present invention has and once can rush the whole installing hole in one end, and the punching cycle is shorter, and the precision of installing hole is higher and regulate the feature of being easy to after installing.

As improvement, four angles of described fixed head are provided with slide opening, described die holder is provided with the guide pillar be slidably connected one to one and with slide opening with slide opening, linear bearing is equipped with between described slide opening and guide pillar, after then linear bearing is arranged, frictional force between slide opening and guide pillar reduces, and then energy consumption during reduction mold work, reduces mold use cost.

As further improvement, described slide block is provided with inclined-plane away from one end of die head, the lower end of described pressure head is provided with the inclined-plane matched with slide block inclined-plane, then the conversion of motion of vertical direction is that mechanism's parts of the motion of horizontal direction are less by subsides inclined-plane, this inclined-plane, structure is simpler, and be that simple frame for movement stability in use is better, service life is also longer.

As improving further 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 center stepped hole, macropore in described center stepped hole is positioned on the 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 through guide hole, the other end of described guide rod crosses respective corresponding guide hole and center stepped hole 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 spacing for the back-moving spring banking stop in the stepped hole macropore of center, the resetting-mechanism parts of this structure are less, structure is simple, preparation cost is lower, for simple mechanical mechanism stability in use is better, service life is also longer, also be convenient to the maintenance in later stage simultaneously, reduce maintenance cost, and guide rod also plays the effect to slider guide, slide block is slided in the process of sliding more stable, then make the stability of punch better, and then ensure the punching precision of installing hole.

As improving further again, the guide pad for drift is provided with in described chute, described guide pad is positioned at position corresponding to chute opening, groove is provided with in the middle part of described guide pad, the straight flange that the cross section of described groove is parallel with two by the base of half arc is formed, between the diameter on the base of half described arc and two parallel straight flanges, spacing is equal to the diameter of column, the described axis of half base arcuate edge and the dead in line of die head, the two side of described groove is equipped with the pilot hole for leading to drift, the width of described guide pad is greater than the width of chute, after then guide pad is arranged, make stability during punch better, and also not easily there is situation about breaking in drift, and then improve precision and the mold use life-span of installing hole, the guide pad of this structure does not need fixed mechanism simultaneously, which saves expense and the installing space thereof of fixed mechanism, and then reduces die cost and reduce mould floor space.

As further improving, the outer surface of described chute opening part is provided with pin, the length direction of described pin and the axis being parallel 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 workman when inserting column, only column need be inserted against baffle plate from opening part, go without the need to needing worker bends down again to aim at, and then improve work task efficiency, and reduce the labour intensity of workman.
