Nesting design (including the cut included) there are four steps away from the plate heat exchanger. Namely, a triangle cut the gap, punching, flanging and pitch turned legs, cut off, 53mm for a step distance; reference manuals 4 die, "Die Design Manual" and take the edge part of the layout will be designed to both sides of the border size measures determined to be 2.5mm, strip width 113mm; red material is q235-a, material thickness ≤ 0.5mm. Figure 2 shows the layout diagram can be seen nesting in the mold form of straight rows, part no tie between the sides, which is characterized material saving. And with the parts out of scrap pieces of the punching process had been separated to facilitate separate collection of waste materials and parts. In addition, due to die on the outside is the edge, spare parts from the machine side of a piece, even on the collection, but also products that combine features of our plant equipment, installed in the stamping machine to wear pieces to achieve red, wearing one piece automation.

    The first step, of material from the automatic feeding device feeding through baffle 18 to enter, four out of the triangle by the side edge of the gap. Charts from the fin can be seen nesting red triangle this step by a fin on both sides of the gap is composed of small triangles.
The second step is a round punch 7, 8 diamond-shaped punch plate heat exchanger punching, punch six trapezoidal cut out 6 foot triangular spacing.
The third step is to flanging punch 9 holes dug out, dug out the spacing of the punch 11 feet.
Final basic shape of the parts are sent out the die from the outer edge and the die cutting knife under the part, workpiece falling into the container.

    Discharge plate 5 hours of work expected to be suppressed, the row on the die to make a smooth exit Flanging Flanging punch hole, trapezoidal top core 19, flange top heart 10, core 16 on top of the spring will be expected to promote a concave top mold, smooth feeding, four small guided Du mounted on the fixed plate 3 through the discharge plate 5, the work of a small lead guide sets the template column into the concave hole. Discharging a very small guide column 5 is always sliding, positioning effective, was underway to protect the punch 6 and 11 role.

     The mold is installed in with an automatic feeding device, high-speed punching punching require precision molds leather high rigidity is good, therefore, uses a four-ball guide pillar mold. Working parts are used crl2mov steel, heat treatment and hardness of 58 - plate heat exchanger 62hbc, with 45 other supporting pieces of steel, discharge plate, baffle, top core components such as a large force for quenched and tempered hardness of 45 ~ 48hrc.
