A high-precision stamping machine

Abstract

The invention discloses a high-precision punching machine. The high-precision punching machine comprises a rack, a terrace die, a hole die and a positioning rod; a feeding rail for conveying sheets and a discharging rail for conveying finished products are arranged on the rack; the terrace die and the hole die are mounted on the rack, and can conduct relative motion so as to complete blanking of the sheets, a plurality of through holes are formed in the hole die, a plurality of bulges are arranged on the terrace die, mold cavities are formed in the bulges, and the feeding rail conveys the sheets to the position between the terrace die and the hole die; the positioning rod is slidably mounted on the rack, and can reach to the mold cavities through the through holes so as to conduct positioning on the sheets. According to the high-precision punching machine, by arranging the through holes in the hole die, and arranging the positioning rod which penetrates through the through holes to conduct positioning on the sheets, the positioning precision and the stability in the punching process can be improved remarkably, it can be seen that the high-precision punching machine is simple and exquisite in structure and stable and reliable in work.

Description

Technical field [0001] The invention relates to a high-precision stamping machine, belonging to the technical field of stamping. Background technique [0002] After the sheet or plate is formed by blister molding, it needs to be separated into individual finished products. In the existing process, the finished product is usually punched out by a punching machine, but the existing punching machine only relies on the concave position for the positioning of the finished product on the sheet when working. The matching of the die and the punch has a low positioning accuracy. In addition, due to the low hardness of the sheet or plate, it is often found that the finished product deviates from the set position during punching, resulting in a high rejection rate. For this reason, the present invention provides a A high-precision punching machine is used to solve the above problems. Summary of the invention [0003] In order to solve the above-mentioned problems, the present invention prov...

Problems solved by technology

[0002] After the sheet or plate is plastic-molded, it needs to be separated into individual finished products. In the existing process, the finished product is generally punched out by a punching machine, but the existing punching machine only relies on the concave position to position the finished product on the sheet during work. The positioning accuracy of the die and the punch is not high. In addition, due to the low hardness of the sheet or plate, it is often found that the finished product deviates from the set position during punching, resulting in a high reject rate. Therefore, the present invention provides a A high-precision punching machine is used to solve the above problems
