Description
Technical field
The utility model relates to field of machining, particularly relates to a kind of punch press for spool punching.
Background technology
Along with scientific and technological development, continuous rise and the extraction of new material and high-pure gas, the seamless steel gas cylinder of lightweight, performance values is more and more applied at more higher-end businesses.The manufacturing for the seamless steel gas cylinder of lightweight, performance values has proposed higher requirement equally, and the spool of cylinder valve one of the parts of gas cylinder key just, it has determined whole air-tightness and security.Its position degree requires very high, and site error is no more than 0.05mm conventionally, and concentricity reaches 0.08mm, and so the hole of high request, relies on traditional mechanical processing technique not only can not reach this required precision, and discharging difficulty.
Traditional punch press at present, its punching die structure, is affected by machine tool accuracy, Mould Machining precision, manual operation etc. larger.When workpiece is thicker, punch press needs greater impact power, drift repeatedly with after workpiece effect easily becomes flexible in process of production, thereby make drift, die gap inhomogeneous, even sometimes drift cutting edge is gnawed scarce, often overproof (the overproof assembling function that also can directly affect of workpiece punching burr) of each hole bur height when punching like this.About 1,000 products of general every making will form removal grind drift.When workpiece sheet material is thick, 3,000 products of general every making, drift is fracture just, will frequently change like this drift, causes mould and die accuracy to decline, thereby affects die life.On the other hand, workpiece discharging difficulty, when manual cleaning, firmly inequality can make drift produce deflection, and then affects punching precision.Therefore there is risk in the quality of product always, and production efficiency is low, and die life is short, and production cost is high.
Granted publication number is that the Chinese patent literature of CN202826501U discloses a kind of punch press, comprise workbench, work mould, support, working beam, staking punch and electric cabinet, described support is arranged on workbench, on described support, there is working beam, staking punch is arranged at described working beam bottom, described electric cabinet is arranged on support one side, on described workbench, there is work mould, air pressure mechanism is arranged at described workbench bottom, described workbench one side has air control switch, described air control switch control air pressure mechanism.
In prior art, punching die loading and unloading material is slow, greatly reduces the efficiency of production, and punching accuracy is not high yet.
Utility model content
The utility model provides a kind of punch press of spool punching, to solve slow, the inefficient problem of spool punching discharging.
The utility model is dealt with problems and is adopted technical scheme to be:
For a punch press for spool punching, comprise the drift and the punching die that cooperatively interact, described punching die comprises:
Be fixed on the base on described punch press;
Be arranged on the middle part of described base, for placing the die of spool;
Be fixed on the stripper on base, this stripper is between die and drift and with the dumping pit of allowing that drift passes.
When punching, drift is processed the spool on die through the dumping pit on stripper.After punching, spool is followed drift and is moved straight up, and valve core movement is during to stripper position, and stripper has limited spool to be continued to move upward, and spool separates with drift, just reaches the object of discharging, needn't manual cleaning, improve production efficiency.
As preferably, described base is provided with four support bars that are arranged in die periphery, and described stripper is fixed on four support bars.
As further preferred, described stripper is provided with and the corresponding installing hole of described post position, and described support bar is provided with the stop nut connecting with described stripper.Need change corresponding stripper according to drift and spool size, the dumping pit of stripper is larger and less than spool size than punch diameter.
When processing different workpieces, need to change different drifts, drift size differs, for the convenient drift that different size is installed, preferably, described punch press is with the upper bolster and the patrix that is fixed with described drift of elevating movement, and this patrix is fixed on described upper bolster.
As preferably, the part that described drift is connected with described patrix is square column, is provided with the square opening mating with described drift in described patrix.Because circular configuration easily rotates, adopt square structure to make drift and patrix in conjunction with more firm, drift is loosening can cause punching precision not high, larger to the wearing and tearing of drift cutting edge.
When punching; drift is easily loosening; particularly spool and drift adhesion are tighter; when discharging, likely make drift come off from patrix; for fear of above-mentioned situation; preferably, described patrix is also provided with the spacing hole of the level being communicated with described square opening, is provided with the position-limitting pin offseting with the sidewall of described drift in this spacing hole.
In order further to strengthen the limit effect to drift, preferably, the sidewall of described drift is provided with limited impression, and described position-limitting pin inserts in this limited impression.
As preferably, described die bottom is provided with chip-removal hole, is provided with the channel of chip removal being communicated with this chip-removal hole on described base.Scrap is directly discharged from chip-removal hole and channel of chip removal, and easy cleaning, is also convenient to continuous production, enhances productivity.
Punching machine structure for spool punching of the present utility model is simply firm, and discharging is convenient, and drift wearing and tearing are little, need not frequently change drift, and punching precision also further improves.
Accompanying drawing explanation
Fig. 1 is a kind of drift and punching die schematic diagram of the punch press for spool punching.
Shown in figure, Reference numeral is as follows:
1, patrix; 2, position-limitting pin; 3, stop nut; 4, stripper; 5, drift; 6, support column; 7, die; 8, base; 9, limited impression; 10, spool; 11, chip-removal hole; 12, channel of chip removal.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described for the punch press of spool punching.
A kind of drift 5 and punching die of cooperatively interacting of comprising for spool punching machine as shown in Figure 1, punching die comprises base 8, base 8 middle parts are provided with die 7, on base, be provided with four around die 7 and be with female fixing hole, four two ends are correspondingly arranged in each fixing hole with externally threaded support column 6, and reinforce with nut.Limiting plate 4 middle parts are provided with the dumping pit mating with drift 5, and limiting plate 4 is also provided with four installing holes corresponding with the fixing hole of base, and support column 6 is located in this installing hole, the stop nut 3 that is positioned at limiting plate 4 both sides is installed on support column 6 limiting plate 4 is clamped.
