Background
Punching machines are common equipment in machining, mainly for punching sheet metal to directly obtain a product shaped according to a die. With the improvement of the technical level, in large-scale automatic production, numerical control punches have become the mainstream instead of manual punches.
Patent document 1 discloses a numerical control full-automatic punching machine, which comprises an automatically controlled plate conveying part, a punching mechanism and a discharging part, wherein the three parts are combined to realize numerical control punching, and the numerical control full-automatic punching machine has the advantages of good production continuity, high material utilization rate and good product quality control. The sheet conveying section of patent document 1 includes a gripping and feeding robot device having a lateral and longitudinal feeding function. The mechanical arm device needs to be retracted to the original position after feeding is completed, the next raw material plate can be punched, in the retraction process of the mechanical arm device, the punching machine is in an empty punching state, the empty punching time is longer, therefore, the efficiency waste of the punching machine is serious, and the overall efficiency of the punching machine is limited.
Patent documents 2, 3, 4, and 5 disclose another numerical control punch press and relay feed mechanism, punching mechanism, and cap discharge mechanism of the punch press. The stamping mechanism of the punch press is as described in patent document 4, adopts two rows of punches and bottom dies which are arranged in a staggered way, and the raw material plate can be stamped by only single longitudinal feeding movement, so that the structure of the manipulator device is simplified; in addition, a relay feed mechanism described in patent document 3 is provided, and the inner and outer manipulators are used for relay feeding in the longitudinal direction, thereby eliminating most of the backlash. The punch press adopts the double rows of punches and the bottom die, the distance between the double rows of dies is a fixed value, if two plates are tightly connected, as shown in fig. 1 and 2, the added width of the leftover materials of the front plate and the rear plate is larger than the gap width of the two rows of punching areas in the single plate, namely Y > X, so that the direct collision between the plates can occur during the connection, and the punched product is unqualified. At present, when the double-row die is used for stamping, blank stamping as shown in fig. 3 is reserved to ensure that stamping normally occurs, and the 2 nd stamping action and the 3 rd stamping action of the arrangement mode are in a half blank stamping state. Therefore, the punch press eliminates most of the empty punch, but the empty punch still exists and cannot be completely eliminated.
