Abstract

The utility model discloses a combination of a knife rest and blades for cutting a parallel flow pipe. The combination of the knife rest and the blades for cutting the parallel flow pipe comprises the knife rest, an upper blade and a lower blade, wherein the upper blade and the lower blade are arranged at the lower end of the knife rest. The two sides of the upper blade are respectively provided with a rolling ball. The rolling balls are connected with a spring inside the knife rest. When cutting is carried out actually, the upper blade and the lower blade operate in a matched mode and cut the parallel flow pipe together, and the cutting edge angle of the upper blade and the cutting edge angle of the lower blade are both designed to be 18 degrees. The two sides of the upper blade are respectively provided with the rolling ball, after the blades cut the parallel flow pipe, the rolling balls can erase an aluminum alloy allowance extruded by cutting of the blades right now, severe flanging does not occur on the fracture of the parallel flow pipe, and a collecting main is convenient to assemble. Meanwhile, the cutting edge angles of the blades are designed to be 18 degrees. Compared with a traditional cutting edge angle, the cutting edge is more pointed, and the cutting allowance can be reduced by a large margin.

Description

A kind of concurrent flow pipe cutting knife and blade unit
Technical field
The utility model relates to concurrent flow pipe cutting processing field, especially a kind of concurrent flow pipe cutting knife and blade unit.
Background technology
Develop rapidly along with auto industry, the evaporimeter that car heat exchanger is used, condenser, the pipe sheet type structure that no longer adopts the copper pipe aluminium foil to make, but the flat flow structure that adopts concurrent flow antipriming pipe (being designated hereinafter simply as the concurrent flow pipe) and aluminum composite foil to make, the concurrent flow pipe has the advantage that volume is little, in light weight, heat exchange performance is good.The concurrent flow pipe is the critical material of full aluminium micro-channel heat exchanger, environmental protection, high efficiency along with the automotive air-conditioning system cold-producing medium, mostly adopt carbon dioxide, requirement of withstand voltage to the concurrent flow pipe will be more and more higher, it is more and more higher that the wall thickness of advection pipe is trended towards required precision more and more thinner, cutting, when scale cut, the smooth requirement of otch was also more and more higher simultaneously.What the cutting of present concurrent flow pipe was adopted is the chipless cutting mode, namely utilize blade to mark tool marks fast up and down simultaneously at the concurrent flow pipe, adopt mechanical system that two ends moment at tool marks place is drawn back then, like this concurrent flow pipe is broken into two-section, finish the scale cutting.
There is following problem in general concurrent flow pipe scale cutting equipment at present, when blade incision aluminium alloy tube wall, can cause the cutting surplus to around dig, thereby the thickness that causes concurrent flow pipe incision exceeds the thickness of itself, increase the burr of incision, with the assembling of header the time, occurred assembling and soldering difficulty so easily.
Summary of the invention
Goal of the invention: at the deficiencies in the prior art, the applicant has designed a kind of concurrent flow pipe cutting knife and blade unit through long-term practical exploration.
Technical scheme: in order to realize the foregoing invention purpose, the technical scheme that the utility model adopts is: a kind of concurrent flow pipe cutting knife and blade unit, comprise knife rest, be arranged on cutter and the bottom knife of knife rest lower end, described cutter both sides respectively are provided with a ball, and described ball is connected with the spring of knife rest inside.During actual the cutting, cutter and bottom knife cooperating are cut the concurrent flow pipe together, and the knife edge angular of described cutter and bottom knife all is designed to 18 °.
Beneficial effect: the utility model compared with prior art, its beneficial effect is:
1, described cutter both sides respectively are provided with a ball, and behind the blade incision concurrent flow pipe, the aluminium alloy surplus that ball can be extruded the blade incision at once is floating, guarantees that can there be serious flange phenomenon in the fracture of concurrent flow pipe, makes things convenient for the assembling of header;
2, the utility model is designed to 18 ° with the knife edge angular of blade, compares with traditional knife edge angular, and is more sharp-pointed, can reduce the cutting surplus significantly;
3, the utility model arranges spring on the top of ball, avoids ball to contact with concurrent flow pipe rigidity, namely causes the crimp of concurrent flow pipe fracture, has improved the yield rate of concurrent flow pipe.
Description of drawings
Fig. 1 is the structural representation of the utility model a kind of concurrent flow pipe cutting knife and blade unit.
Fig. 2 is cutter and bottom knife assembling schematic diagram.
The specific embodiment
Below by a most preferred embodiment, the technical program is elaborated, but protection domain of the present utility model is not limited to described embodiment.
As shown in Figure 1, a kind of concurrent flow pipe cutting knife and blade unit comprise knife rest 1 and the cutter 2 that is arranged on knife rest 1 lower end, and described cutter 2 both sides respectively are provided with a ball 3, and described ball 3 is connected with the spring 4 of knife rest 1 inside.Behind the cutter 2 incision concurrent flow pipes, the aluminium alloy surplus that the ball 3 on both sides is extruded with cutter 2 incisions soon is floating.
During actual the cutting, as shown in Figure 2, cutter 2 and bottom knife 6 cooperatings are cut concurrent flow pipe 5 together, and the knife edge angular 21 of described cutter 2 is 18 °, and the knife edge angular that is arranged at the bottom knife 6 of concurrent flow pipe 5 lower ends also is 18 °.
The above only is preferred embodiment of the present utility model; be noted that for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.

Claims (2)
