Description
Technical field
The utility model belongs to the molded machine tool field of fin Special punching, particularly relates to a kind of fin forming machine bottom knockout follower structure.
Background technology
Aluminum fin-stock is a kind of component be widely used on the equipment such as automobile aluminum radiator of water tank, cocurrent flow type condenser, parallel flow evaporators, radiator or surface cooler, air quantity variable air conditioner cabinet, fan coil and heat exchanger, its Main Function is the effect playing heat radiation, plate-fin heat exchanger has compact conformation, lightweight, the advantage of heat exchange efficiency, especially heat exchange efficiency are higher than other heat exchangers by 30%.Fin is the critical component of plate-fin heat exchanger, accounts for more than 80% of whole heat exchanger volume, and the precision of fin directly affects the heat exchange efficiency of plate-fin heat exchanger and reliable, security performance.
Also have special in produce the forming machine of fin in the market, the Chinese utility model patent " a kind of bending stamper " being 200720114255.6 (notification number is CN201077154Y) as the patent No. discloses a kind of fin molding machine, this kind of lathe can meet the processing and forming requirement of common fin, but it exists many defects, the processing and forming of plate-fin heat exchanger high accuracy fin can not be applied to.Along with the upgrading of plate-fin heat exchanger industry, pressure and the heat transfer rate of heat exchanger are had higher requirement, this all must rely on the formed precision improving plate-fin heat exchanger fin to ensure, develops the special purpose machine tool that can meet plate-fin heat exchanger high accuracy fin forming requirements very urgent.The mould of new plate-fin heat exchanger fin adopts fixing ejection technique.
A kind ofly as disclosed in the patent No. Chinese utility model patent " die carrier structure of forming machine for fin of plate-fin heat " that is ZL201120418387.4 (notification number is CN202278095U) adopt fixing ejection technique, before and after in this structure, bottom knock out bar maintains static, because counterdie has the motion of a straight feeding in finned blade forming technique, so to the problem that there is the demoulding demoulding effectively on one side inefficacy during bottom knockout.When shaping aluminum foil material Thickness Ratio is larger time, the demoulding on one side effectively just can realize fin to bottom knockout, and when automobile finned blade forming, because this kind of fin aluminum foil material thickness is smaller, the fin that this problem will cause the gap of cutter and bottom knock out bar larger can not to bottom knockout.
Summary of the invention
Technical problem to be solved in the utility model is the fin forming machine bottom knockout follower structure providing a kind of stripper plate for the demoulding can be synchronized with the movement with counterdie anterior-posterior horizontal for above-mentioned prior art present situation, and this structure can ensure effective demoulding of fin.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of fin forming machine bottom knockout follower structure, and comprise the spaced two pieces of risers in left and right, riser is arranged along the longitudinal direction; Two between left and right every and the material toggling guide rod longitudinally arranged, material toggling guide rod driven by reciprocating feeding mechanism and can before and after slippage; It is characterized in that: the middle part of described riser has mounting hole; described material toggling guide rod be upward through mounting hole and can within it before and after slippage; be connected with a demoulding slide plate after material toggling guide rod passes mounting hole; and make demoulding slide plate can with the slippage of material toggling guide rod; the top of demoulding slide plate is also provided with the stripper plate of two time intervals settings; form the gap passed for the lower cutter in counterdie between two stripper plates, the two ends, left and right of stripper plate are fixed on the demoulding slide plate of corresponding side by the first screw.
For guaranteeing smooth slippage before and after the relative riser of demoulding slide plate; the cross section of above-mentioned demoulding slide plate is T-shaped; the upper surface of described riser is fixed with about two spaced draw runners; the vertical portion of described demoulding slide plate is between two draw runners; the bottom surface of the horizontal part of demoulding slide plate is shelved on described draw runner, and slippage before and after the relative draw runner of energy.Draw runner can adopt copper material to make, and makes demoulding slide plate more smooth and easy relative to draw runner slippage.
Above-mentioned draw runner has ladder hole, and the second screw is threaded with demoulding slide plate through after ladder hole, and the head of the second screw is sunken in the macropore portion of ladder hole.
Above-mentioned demoulding slide plate has the manhole that size and material toggling guide rod profile match, described material toggling guide rod is located in this manhole.It is the simple connected mode of a kind of material toggling guide rod and demoulding slide plate, guarantees that the movable demoulding slide plate that can drive of material toggling guide rod moves forward and backward.
The two ends, left and right of above-mentioned stripper plate are equipped with the bar hole that length direction is arranged along the longitudinal direction, and described first screw is threaded with demoulding slide plate through after bar hole.This structure can regulate the gap between two stripper plates, and this gap is adapted to the lower cutter passed, and rational gap more effectively can ensure the smooth demoulding of fin.
Compared with prior art, the utility model has the advantage of: the counterdie for finned blade forming and the stripper plate in order to the demoulding are all by material toggling guide rod Direct driver, counterdie and stripper plate can level of synchronization be moved, lower cutter in finned blade forming counterdie and the gap of stripper plate remain constant, and the downward demoulding gap of fin immobilizes, and ensure that effective demoulding on fin both sides.
