Description
technical field:
The present invention relates to stair step carrier bar manufacture field, relate in particular to a kind of accompanying drawing step carrier bar essence punching die.
background technology:
escalator is a kind of means of transport that transports pedestrian in conveyer belt mode.Electronic Fu ladder is generally tilting, and pedestrian is automatic step of walking on the station, one end of staircase, just can automatically be brought to the other end of staircase, and in way, step Hui Yi road keeps level.Escalator is all to carry out transmission by chain, and these chains are to be all formed by connecting by some carrier bars and bearing pin.For the convenient bearing pin of installing, on carrier bar, be all provided with the pin-and-hole for bearing pin is installed.On traditional carrier bar, pin-and-hole is mainly by pulling eye, hits hole and Vehicle Processing three process completes, and this processing technology operation is many, and production efficiency is slow, and the aperture precision of product is also lower.
summary of the invention:
Technical problem to be solved by this invention is that a kind of stair step carrier bar essence punching die that can reduce operation raising Product Precision is provided.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions: a kind of stair step carrier bar essence punching die, by upper die component and counterdie module composition, described upper die component comprises patrix frame plate, patrix frame plate top is connected with punch press, and bottom is disposed with upper padding plate, upper mounted plate and stripper from top to bottom; The center of described upper padding plate and upper mounted plate is provided with through hole, and spring is installed in through hole, and the two ends up and down of described spring are inconsistent with patrix frame plate and stripper respectively; The bottom of described upper padding plate is provided with two drifts that supported by PM HSS and a guide pillar, described drift is arranged on the both sides of spring, guide pillar is positioned at the wherein outside of a drift, the end of described drift and guide pillar runs through upper mounted plate and stripper, and the end of guide pillar extends to the outside of stripper; Between described stripper and upper mounted plate, have gap, stripper is connected with patrix frame plate with upper padding plate through upper mounted plate by contour unloading bolt; Described lower membrane module comprises counterdie frame plate, and counterdie frame plate is fixedly installed on work bench of punch press, and its top is provided with two for the locating piece of carrier bar and pilot hole corresponding with guide pillar and that match are installed; Described locating piece is flexibly connected with counterdie frame plate by adjustable bolt, is provided with two slug holes on the counterdie frame plate between two locating pieces, and this slug hole is corresponding with drift.
As preferably, described drift is fixedly connected with upper padding plate by gim peg.
Compared with prior art, usefulness of the present invention is: the drift of this stair step carrier bar essence punching die can meet the punching press requirement that reaches 40 ° of Rockwells after carrier bar heat treatment, by traditional pulling eye, hit hole and Vehicle Processing three process boil down to one procedure, improve production efficiency, and within can the be controlled at ± 0.02mm of diplopore spacing tolerance on carrier bar, the straight wall of hole wall reaches more than 85%, has improved machining accuracy.

detailed description of the invention:
Describe the present invention below in conjunction with the drawings and the specific embodiments:
A kind of stair step carrier bar essence punching die shown in Fig. 1, by upper die component and counterdie module composition, described upper die component comprises patrix frame plate 1, and patrix frame plate 1 top is connected with punch press, and bottom is disposed with upper padding plate 2, upper mounted plate 3 and stripper 4 from top to bottom; The center of described upper padding plate 2 and upper mounted plate 3 is provided with through hole, and spring 9 is installed in through hole, and the two ends up and down of described spring 9 are inconsistent with patrix frame plate 1 and stripper 4 respectively; The bottom of described upper padding plate 2 is provided with two drifts that supported by PM HSS 6 and a guide pillar 8, described drift 6 is arranged on the both sides of spring 9, between itself and upper padding plate 2, be fixedly connected with by gim peg 7, described guide pillar 8 is positioned at the wherein outside of a drift 6, the end of described drift 6 and guide pillar 8 runs through upper mounted plate 3 and stripper 4, and the end of guide pillar 8 extends to the outside of stripper 4; Between described stripper 4 and upper mounted plate 3, have gap, stripper 4 is connected with patrix frame plate 1 with upper padding plate 2 through upper mounted plate 3 by contour unloading bolt 5; Described lower membrane module comprises counterdie frame plate 10, and counterdie frame plate 10 is fixedly installed on work bench of punch press, and its top is provided with two and sees accompanying drawing 2 for carrier bar 14(is installed) locating piece 11 and pilot hole 15 corresponding with guide pillar 8 and that match; Described locating piece 11 is flexibly connected with counterdie frame plate 10 by adjustable bolt 12, is provided with two slug holes 13 on the counterdie frame plate 10 between two locating pieces 11, and this slug hole 13 is corresponding with drift 6.
Its concrete occupation mode is as follows, according to the size of carrier bar 14, regulate locating piece 11, then carrier bar 14 is placed between locating piece 11, then start punch press switch, patrix frame plate 1 drives the upper padding plate 2 of its below, upper mounted plate 3 and stripper 4 move down, guide pillar 8 steadily enters in pilot hole 16, then stripper 4 is spacing by locating piece 11, patrix frame plate 1, upper padding plate 2 and upper mounted plate 3 drive drift 6 to continue to move down, for thering is gap between stripper 4 and upper mounted plate 3, and on counterdie frame plate 10, be provided with the slug hole 13 corresponding and identical with drift 6, therefore drift 6 can continue to press down after contact carrier bar 14, drift 6 falls into the waste material of going out on carrier bar 14 in the slug hole 13 on counterdie frame plate 10, after punching press completes, stripper 4, upper mounted plate 3, upper padding plate 2 and 1 backhaul of patrix frame plate, because carrier bar 14 is easily stuck in backhaul together on drift after drift 6 punching presses, therefore in backhaul process, because stripper 4 is subject to the downward resilience of spring 9, and drift 6 follows upper padding plate 2 to continue backhaul, after once the end of drift 6 enters stripper 4, the carrier bar 14 being stuck on drift 6 will be backed off by stripper 4, complete discharging, then carrier bar 14 is taken out.
The drift 6 of this stair step carrier bar essence punching die can meet the punching press requirement that reaches 40 ° of Rockwells after carrier bar heat treatment, by traditional pulling eye, hit hole and Vehicle Processing three process boil down to one procedure, improve production efficiency, and within can the be controlled at ± 0.02mm of diplopore spacing tolerance on carrier bar 14, the straight wall of hole wall reaches more than 85%, has improved machining accuracy.
It is emphasized that: be only preferred embodiment of the present invention above, not the present invention is done to any pro forma restriction, any simple modification, equivalent variations and modification that every foundation technical spirit of the present invention is done above embodiment, all still belong in the scope of technical solution of the present invention.
