Abstract
The utility model discloses a breakpoint length cutting tool, which comprises a mounting base (1) and a cutting edge head (2) on the upper end face of the base, and is characterized in that the upper end of the cutting edge head (2) is provided with 2-5 open notches (3). The breakpoint length cutting tool has the advantages of simple and compact structure, convenience for manufacture, capabilities of effectively removing burrs on fins, cutting aluminum oils and guaranteeing product quality, and the like.
Description
Technical field
The utility model relates to cutter, and especially a kind of fin punch press is suitable for breakpoint rip cutting cutter.
Background technology
The former reason evaporimeter of air-conditioning work, condenser, compressor, capillary, controller five big parts are formed.When producing evaporimeter and condenser fin, because portioned product needs, must produce the single hole product, the fin punch press burr in various degree can occur when producing the single hole product, and the reason that produces burr is:
1) it is excessive intermittence to occur after punch press list double jump production a period of time, causes drawing the material cross bar to be swung, thereby produces burr;
2 aluminium foils are not well located in forming process, cause aluminium foil to occur swinging in the mould the inside, and longitudinal knife is not cut at same position when work, thereby burr occurs;
3 when producing the single hole product, and eccentric disc and draw the cooperation of material mechanism not adjust is not in the optimum position thereby appear at when drawing single hole, cause longitudinal knife deviation when cutting product, to occur, produces burr;
4) burr of product appearance brings quality and potential safety hazard to product, and the fin punch press is when producing the single hole product; With use the rip cutting cutting edge roundness to adopt linear type structure always; Have the design un-reasonable phenomenon, former product does not almost have the single hole product to occur, so to not influence of quality.Along with the change of product structure, increasing product all has single hole to exist, thereby causes a large amount of burrs to occur.
Summary of the invention
The purpose of the utility model provides a kind of simple in structure, is provided with the breakpoint rip cutting cutter of opening notch at the rip cutting cutting edge roundness.
The technical scheme that purpose adopts of the utility model is:
The cutting edge head that comprises mounting base and this pedestal upper surface, there are 2～5 opening notches its described cutting edge head upper end.
The utility model, described 2～5 opening notches are distributed in the two ends of cutting edge head.
The utility model, described 2～5 opening notches are distributed in the centre and the two ends of cutting edge head.
The utility model has the opening notch at edge of a knife head; Be in die cavity, to move step pitch according to aluminium foil; Burr is not created in two ends when having single double jump; So the opening notch need be set up in rip cutting cutter two ends, aluminium foil pulling amount was 1/2 of a normal arrangement when next produced the single hole step pitch, so need set up opening notch (centre of cutting edge) at 1/2 of cutting edge head.Each part is selected needs 2～5 opening notches can guarantee that burr causes burr to drop fully by interlock on the fin.
The utlity model has simple and compact for structurely, easy to make, can effectively remove burr on the fin, and reach aluminium foil is cut open, guarantee advantages such as product quality.
Description of drawings
Further specify the utility model below in conjunction with accompanying drawing.
Fig. 1 is the utility model embodiment perspective view.
Among the figure: 1-mounting base, 2-cutting edge head, 3-opening notch.
The specific embodiment
As shown in Figure 1, comprise the cutting edge head 2 of mounting base 1 and this pedestal upper surface, there are 2～5 opening notches 3 its described cutting edge head 2 upper ends.Described 2～5 opening notches 3 are distributed in the two ends of cutting edge head 2.Described 2～5 opening notches are distributed in the centre and the two ends of cutting edge head 2.
Claims (3)
1. breakpoint rip cutting cutter comprises the cutting edge head (2) of mounting base (1) and this pedestal upper surface it is characterized in that there are 2～5 opening notches (3) described cutting edge head (2) upper end.
2. a kind of breakpoint rip cutting cutter according to claim 1 is characterized in that described 2～5 opening notches (3) are distributed in the two ends of cutting edge head (2).
