Technical parameters of crank press for metal stamping equipment

The hardware stamping equipment crank press mainly has the following technical parameters; let’s look at it in detail; 1. Nominal pressure; The nominal pressure of the hardware stamping equipment crank press refers to when the slider is a certain distance from the bottom dead center or When the crank rotates to a certain angle from the bottom dead center, the maximum force allowed on the slider; for example, the nominal pressure of the J31315 press is 3150KN, which means that the slider is 10.5mm from the bottom dead center or the crank rotates When it is 20° from the bottom dead center, the maximum allowable force on the slider is 3150KN; the nominal pressure is a main technical parameter of the press, and the nominal pressure of the pressure in our country has been serialized; 2. The stroke of the slider; It refers to the distance traveled by the slider from the top dead center to the bottom dead center, and its size varies with the process application and nominal pressure; for example, the stroke of the press used for punching is small, and the press used for drawing The stroke is large; 3. The number of strokes; it refers to the number of times the slider reciprocates from top dead center to bottom dead center and then back to top dead center per minute, generally small presses and presses used for blanking The number of strokes is more, and the number of strokes of large presses and deep drawing presses is less; 4. Closing height, which refers to the distance between the lower plane of the slider and the upper surface of the worktable when the slider is at the bottom dead center; When the closed height adjustment device adjusts the slider to the highest position, the closed height is the largest, which is called the maximum closed height; when the slider is adjusted to the lowest position, the adjustable range of the closed height from maximum to minimum is called the closed height adjustment; 5 , Mold loading height; when the work table is equipped with a work pad and the slider is at the bottom dead center, the distance from the lower plane of the slider to the plane of the pad is called the mold loading height; the maximum closed height state is called the mold loading height Is the maximum installation height, the installation height in the minimum closed height state is called the minimum installation height; the difference between the installation height and the closed height is the thickness of the backing plate; 6. The connecting rod adjustment length; the connecting rod adjustment length is also called installation Die height adjustment; the connecting rod of the crank press of the hardware stamping equipment is usually made of two parts, so that the length can be adjusted; by changing the length of the connecting rod, the closing height of the press can be changed to meet the installation requirements of different closed height molds; 7. In addition to the above-mentioned main parameters, there are also table size, die handle size, etc.; Recommended article: Basic process of stamping parts processing project Previous: Stamping parts processing factory talks about the lower pipe cutting and tenon die
