The specific embodiment
Embodiment is described in further detail the present invention below in conjunction with accompanying drawing.
Shown in Fig. 1～11, be a preferred embodiment of the present invention.
A kind of Multi-cutter forming die for fins of plate-fin, it is made of the separable part of the upper die and the part of the lower die that are arranged on the frame of punch.
The part of the upper die comprises the upper cutter head 1a that the relative frame of punch of energy moves up and down, and and press machine is fixed and upper left stripper plate 2a and the upper right stripper plate 3a of each other horizontal interval setting, and the bottom surface of upper left stripper plate 2a and upper right stripper plate 3a is positioned on the same level face; Upper cutter head 1a is provided with mounting groove 11a, be fixed with the 4a that fixes a cutting tool that two rows are intervally installed in the upper mounting groove 11a, certainly also can be three rows or the 4a that fixes a cutting tool that arranges more, the 4a that fixes a cutting tool is rectangular tabular, the interval that adjacent two rows fix a cutting tool between the 4a is corresponding with the width of each tooth of fin of the moulding of wanting, every row 4a that fixes a cutting tool is clamped by the clamping plate 5a that fixes a cutting tool of both sides, the clamping plate 5a that fixes a cutting tool exposes upper cutter head 1a downwards, the 4a that fixes a cutting tool exposes the clamping plate 5a that fixes a cutting tool downwards, the distance that the 4a that fixes a cutting tool exposes the clamping plate 5a that fixes a cutting tool is a fixed value, and fix a cutting tool 4a and the clamping plate 5a that fixes a cutting tool can just pass from the gap between upper left stripper plate 2a and the upper right stripper plate 3a.
The 4a that fixes a cutting tool is fixed in the mounting groove 11a in the following ways with the clamping plate 5a that fixes a cutting tool: the L shaped groove of upper mounting groove 11a for running through along its length, fix a cutting tool 4a and the clamping plate 5a that fixes a cutting tool clamps and places this L shaped groove by the two backing plate 6a that fix a cutting tool, upper cutter head 1a right side wall is fixed with the pressing plate 7a that fixes a cutting tool by a plurality of bolts 9, be provided with lock washer 10 between the head of bolt 9 and the upper cutter head 1a right side wall, this pressing plate 7a that fixes a cutting tool 4a that to fix a cutting tool, fix a cutting tool clamping plate 5a and fix a cutting tool backing plate 6a in left and right directions is pressed on L shaped groove, the pressing plate 7a inner face of fixing a cutting tool has many anti-skidding striped 71a that arrange along its length; The two side is fixed with respectively upper side guide 8a by bolt 9 before and after the upper cutter head 1a, be provided with lock washer 10 between the sidewall before and after the head of bolt 9 and the upper cutter head 1a, on this side guide 8a will fix a cutting tool 4a, clamping plate 5a and fix a cutting tool backing plate 6a in fore-and-aft direction is pressed on L shaped groove fixes a cutting tool;
The part of the lower die comprises the relative frame of punch of energy up and down and the lower tool rest 1b of move left and right, and and press machine is fixed and bottom left stripper plate 2b and the bottom right stripper plate 3b of each other horizontal interval setting, the end face of bottom left stripper plate 2b and bottom right stripper plate 3b is positioned on the same level face, and between the end face of the bottom surface of upper left stripper plate 2a and upper right stripper plate 3a and bottom left stripper plate 2b and bottom right stripper plate 3b space D is arranged, this space D is identical with the height of fin, lower tool rest 1b is provided with lower mounting groove 11b, be fixed with the bottom tool 4b that two rows are intervally installed in the lower mounting groove 11b, certainly also can be three rows or arrange bottom tool 4b more, bottom tool 4b is rectangular tabular, interval between adjacent two row's bottom tool 4b is corresponding with the width of each tooth of fin of the moulding of wanting, the interval that two rows fix a cutting tool between the 4a is identical with the interval between two row's bottom tool 4b, every row's bottom tool 4b is clamped by the bottom tool clamping plate 5b of both sides, bottom tool clamping plate 5b upwards exposes lower tool rest 1b, bottom tool 1b upwards exposes bottom tool clamping plate 5b, the 4a length of fixing a cutting tool that exposes outside the clamping plate 5a that fixes a cutting tool is identical with the bottom tool 1b length that exposes outside bottom tool clamping plate 5b, and bottom tool 4b and bottom tool clamping plate 5b can pass from the gap between bottom left stripper plate 2b and the bottom right stripper plate 3b and can left and right sides slippage.
If plate-fin heat exchanger fin is flat type, as shown in Figure 4, fix a cutting tool so 4a and bottom tool 4b are the flat cutter.
If plate-fin heat exchanger fin is sawtooth pattern, as shown in Figure 5, fix a cutting tool so 4a and bottom tool 4b are the zigzag cutter.
If plate-fin heat exchanger fin is ripple type, as shown in Figure 6, fix a cutting tool so 4a and bottom tool 4b are the corrugated cutter.
Below take the mould of the plate-fin heat exchanger fin of producing flat type as example, the operation principle of this mould is described.
Because fix a cutting tool 4a and the bottom tool 4b absolute fix of upper and lower mould, the 4a length of fixing a cutting tool that exposes outside the clamping plate 5a that fixes a cutting tool is identical with the bottom tool 1b length that exposes outside bottom tool clamping plate 5b, in fin 12 forming processes, during the upper and lower mould matched moulds, just there is individual extrusion process the bottom surface of fixing a cutting tool to fin 12 bottom surfaces, can stamp out the plane at the bottom of the wing of fin 12;
As shown in Figure 7, then, lower tool rest 1b drives bottom tool 4b and bottom tool clamping plate 5b moves down, and bottom tool 4b can withdraw from fin 12 downward opening teeth;
As shown in Figure 8, then, lower tool rest 1b moves to left;
As shown in Figure 9, descending tool rest 1b to drive on bottom tool 4b and the bottom tool clamping plate 5b moves again, one of them bottom tool 4b punching press bending forming goes out the next tooth of fin 12, and another bottom tool 4b carries out two times punch to last tooth, finish shaping and typing, eliminated the impact of fin 12 resiliences on pitch accuracy;
As shown in figure 10, upper cutter head 1a drives on fix a cutting tool 4a and the clamping plate 5a that fixes a cutting tool and moves again, the 4a that fixes a cutting tool because being limited between the end face of the bottom surface of upper left stripper plate 2a and upper right stripper plate 3a and bottom left stripper plate 2b and bottom right stripper plate 3b, fin 12 has in the space D, so can withdraw from the opening up tooth of fin 12;
As shown in figure 11, then, lower tool rest 1b moves to right, because bottom tool 4b is also in fin 12 downward opening teeth, so lower tool rest 1b moves to right and drives whole fin 12 and move to right;
As shown in Figure 1, then upper cutter head 1a drives fix a cutting tool 4a and the clamping plate 5a that fixes a cutting tool and moves down, one of them 4a punching press bending forming of fixing a cutting tool goes out the next tooth of fin 12, and another 4a that fixes a cutting tool carries out two times punch to last tooth, finish shaping and typing, eliminated the impact of fin 12 resiliences on pitch accuracy.
The circulation said process.
