Description
Technical field
The utility model relates to, and is specifically related to an Albatra metal-key progressive die.
Background technology
Key is accessory necessary in lockset, and its workmanship directly affects serviceability.This product production quantity is large, and material is H62 brass, and thickness is 2mm.Adopt the simple mould of single operation to produce in the past, not only operation is many, productivity ratio is low, and the dimensional accuracy of product does not often reach the requirement of technology defined.At present, this product can not meet the needs that lockset industry is competed day by day, along with improving constantly of product productivity ratio and quality, and improves the working condition of workman and reduces the requirement of product cost, must change backward Sheet Metal Forming Technology.
Utility model content
The purpose of this utility model is for solving above-mentioned deficiency, provides an Albatra metal-key progressive die.
The purpose of this utility model is achieved through the following technical solutions:
One Albatra metal-key progressive die, comprise upper die and lower die, patrix comprises upper bolster, backing plate, unloading bolt, blanking punch, die shank, piercing punch, punch retainer, polyurethane rubber, stripper and interim pin stop, upper bolster is in the top, upper bolster connection backing plate, backing plate connects punch retainer, unloading bolt embeds upper bolster, blanking punch is connection backing plate and counterdie respectively, die shank connection backing plate, piercing punch one end connection backing plate, the other end connects counterdie, punch retainer connects polyurethane rubber, polyurethane rubber connects stripper, counterdie comprises die shoe, movable pin stop, stock supporting plate and die, die shoe is arranged on bottom, die shoe connects die, movable pin stop is arranged on inside mould upstream, stock supporting plate is arranged on outside mould upstream.
On die, plane is provided with the two guide chis in left and right.
The both sides of mould are provided with two guide pillars and corresponding guide pin bushing, and guide pin bushing is enclosed within guide pillar top.
Negative molding material selects quality carbon tool steel T10A, heat treatment hardness 60 ~ 64HRC, and piercing punch and blanking punch all select high-chromium alloy tool steel Cr12MoV, heat treatment hardness 58 ~ 63HRC.
The utility model has effect useful as follows:
The utility model is reasonable in design, easy to use, adopts that punching---blanking continuous punching work step progressive die is produced, and can improve parts quality significantly and productivity ratio production cost is low, remarkable in economical benefits, have good application prospect.
Accompanying drawing explanation
Fig. 1 is side-looking structural representation of the present utility model;
Fig. 2 is plan structure schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described:
As shown in Figure 1, one Albatra metal-key progressive die, comprise upper die and lower die, patrix comprises upper bolster 1, backing plate 2, unloading bolt 3, blanking punch 4, die shank 5, piercing punch 6, punch retainer 7, polyurethane rubber 9, stripper 10 and interim pin stop 17, upper bolster 1 is in the top, upper bolster 1 connection backing plate 2, backing plate 2 connects punch retainer 7, unloading bolt 3 embeds upper bolster 1, blanking punch 4 is connection backing plate 2 and counterdie respectively, die shank 5 connection backing plate 2, piercing punch 6 one end connection backing plate 2, the other end connects counterdie, punch retainer 7 connects polyurethane rubber 9, polyurethane rubber 9 connects stripper 10, counterdie comprises die shoe 13, movable pin stop 14, stock supporting plate 15 and die 16, die shoe 13 is arranged on bottom, die shoe 13 connects die 16, movable pin stop 14 is arranged on inside mould upstream, stock supporting plate 15 is arranged on outside mould upstream.
On die, plane is provided with the two guide chis 11 in left and right.
The both sides of mould are provided with two guide pillars 12 and corresponding guide pin bushing 8, and guide pin bushing 8 is enclosed within guide pillar 12 top.
Negative molding material selects quality carbon tool steel T10A, heat treatment hardness 60 ~ 64HRC, and piercing punch and blanking punch all select high-chromium alloy tool steel Cr12MoV, heat treatment hardness 58 ~ 63HRC.
The course of work: first billot is sent to along guide chi, and be subject to the restriction of interim pin stop, press ram decline, piercing punch carries out punching operation, slide block upwards backhaul time, because stripper is by the tension force effect of polyurethane rubber, billot is unloaded from piercing punch, and then billot is sent to, be subject to the restriction of movable pin stop, slide block, to down stroke, completes punching and blanking operation simultaneously.Like this, sequentially carry out punching press and send work to, punched scrap and product spill from the bottom outlet of die.
