Dedicated, professional, quality !
The main part describes SAMHOOR high-speed presses dies
Stamping die comprising the child inflammation typical parts:
① mold. Including the upper and lower mold base, guide pins and bushings, mold handle, is the basis of member dies, the other parts are respectively mounted in the upper and lower mold fixed seat, the relative position and movement of the upper and lower mold base to ensure the accuracy of the guide pins and bushings, therefore guide between the guide sleeve of the column should be less than the blanking gap. When the guide pin is located located next to touch base, to ensure that at the stroke dead center on the end face of the guide post on the die below the top surface at least 5 to 10 mm, guide posts should be scheduled as far away from the module, the operating portion of the pressure plate, It should enable the operator to feed the upper arm when a member crossed the guide post. Shang Gao of the guide post should die at the highest point, resulting in impaired sense of doubt.
Pull mode planar dimension, especially the size of the longitudinal direction of the article should adapt, too big too small are not conducive to the operation. If you have an inner mold stopper, after a good tune mold split over the best, and then press to complete the installation, so as not to interfere with the operation. Some molds (blanking, punching type mold) is a member or clearing convenient waste, to be in the mold under the mat strip. As shown in Figure 55. The best pad strip screwed together with the template, the thickness of the cushion of the two should be absolutely equal. Pad spacing to be able to strip out the pieces prevail, not too much, so as not to break the template.
② working parts.
Direct cause parts molded or punched parts, such as convex, concave molds, known as the working parts. As part of its work size punch profile, the concave-shaped mold, ejector by the shape of the workpiece size to be, but in the determination of other dimensions, it should meet the safety requirements:
A, should have sufficient strength, fracture or damage is not allowed in the stamping process.
B, materials and heat treatment requirements should be appropriate to prevent the hardness is too high and brittle.
C, should be milled slot empty-handed operation at the location.
D, exposed surfaces should pour blunt edges.
③ positioning parts. Lead foot, fixed plate, fixed feed pin, guide pin positive, side plate, etc. to determine the placement of the blank parts are referred to locate a part or parts of a given material. Design positioning parts should be considered easy operation, should there have been positioned to facilitate the observation position, preferably in front push position, external position and guide the positive pin bit and so on.
④ press materials and the top of the part. As it almost out the pieces and clean waste, mold equipped with an ejector, care plate, by a spring, rubber or punch cushion rod support, can move up and down. Top of the member design should have enough top output, motion to limited spaces, to minimize the closed area, should milled slot empty-handed in the operating position, the lower die exposed material pull of care to be provided with protective plate four tune prevent fingers into or foreign matter into the exposed surface should pour obtuse angle shuttle.
⑤ standard parts. Screws, nuts, springs, pins, Juan Zhi and so on. Large amount of die standard parts, the design should ensure a secure, resilient ejection needs to avoid exposure in the operating position of the surface fastener on persons to prevent bumps and impede operations.
