Miyoshi speed punch slider stroke and speed Comments
Speed punch slider is molded product processing speed punch press parts due to the operation of high-pressure high-speed slider, so material is generally large, high strength steel, high-speed presses with productivity slider stroke size and speed has a decisive factor.
1. Slide stroke:
Two poles slider up and down movement known as the top dead center and bottom dead center. Movement from the top dead center to bottom dead center called the working stroke. From the bottom dead center to the top dead point of the return stroke, the vertical distance between the two poles is called the slide stroke length (ie, twice the crank radius), adjust the length of the crankshaft stroke length can be adjusted, slide stroke length generally increases with the increase in nominal, but taking into account some of the parts of the common and often travel near tonnage equal length.
2. Slider speed:
Slide from the top dead point to the lower dead point per minute, then back to the top dead center of the reciprocating number of times. Slide stroke number determines the productivity of the press, the current design of this parameter press a growing trend, but due to the slide stroke length and stroke frequency slider determines the speed of the slider, and this rate has been affected by the impact of parts and materials plastic deformation and automatic feeding affect the accuracy of the work agency coordination and mold working life, so high-speed punch manufacturers in the production design must be carefully considered. Slider trips listed in the specification refers to general high-speed punch presses in the no-load (ie under no load stamping) number of times in the press under load (ie when the press load) size slider trips with load (strictly speaking, the size of the work done) reduce the number of strokes a different value when compared with no load.
Ram stroke speed and stroke is inversely proportional to the slider, the longer the trip, the slower the speed. Selection on the slider to wear resistance, high coefficient of friction, high strength materials, high-speed punch slider Miyoshi manufacturing technology excellence, zero seam guide, which greatly improves the accuracy of high-speed presses.
