Abstract
The invention discloses a rip cutting blade structure of an air-conditioner fin, which comprises a rip cutting blade. The two end parts of the rip cutting blade are arc structures, a groove is arranged at the secondarily repeated cutting position of the rip cutting blade edge. The rip cutting blade structure improves the shape of the cutting edge of the rip cutting up and down in the prior art, and avoids the repeated cutting in the single hop action and dual-hop action by arranging the groove at the secondarily repeated cutting position of the rip cutting blade edge, further the problem of repeatedly cutting burr is solved.
Description
Technical field
The present invention relates to air-conditioner fin die, relate in particular to the longitudinal knife blade shape design in the slit sub-die in the air-conditioner fin die.
Background technology
Air-conditioner fin is the vitals on the Gilled heat exchanger in the aircondition, and its major function is to increase heat exchange area, improve heat exchanger effectiveness.Air-conditioner fin generally is made by the air-conditioner fin die punching press.Air-conditioner fin die comprises a plurality of submodules, and slit sub-die wherein is used for finishing the rip cutting operation of making air-conditioner fin.Rip cutting claims out again bar, its effect be utilize rip cutting up and down cutter to cutting, with the wide desired fin width of client that is cut into of the material of view picture, simultaneously, rip cutting up and down cutter to cut length at the control lapping defect, reduce play a part aspect the fin distortion very important.
Rip cutting up and down cutter adjust to suitablely for after cutting length, for the different length requirement of fin, such as the length of a film requirement of odd number hole count, mould will have the action of single double jump usually.Now take step pitch as 25mm, the mould of two steppings explains single double jump as example, the normal feeding step pitch of this mould is 50mm, for the finned length of wanting the odd number hole count or the customer requirement that can debug the fin that abnormity cuts, this need to could realize by the action of single-hop in the feeding process, namely only sending a step is 25 mm, so, then has a material section secondary can occur and repeats to cut, this can cause fin burr to occur or the palpus that becomes mildewed, and finally affects total quality and the outward appearance of fin.
The rip cutting of the prior art up and down blade shape of cutter is the straight knife shape, and it can not solve the Burr Problem that repeats to cut in single double jump action and cause.
Summary of the invention
The applicant improves for above-mentioned shortcoming of the prior art, provide a kind of rip cutting up and down cutter append little groove structure, it has overcome the up and down existing deficiency of cutter of rip cutting of the prior art, can avoid repeating to cut, and makes to repeat to cut Burr Problem and solved.
Technical scheme of the present invention is as follows:
A kind of longitudinal knife chip architecture of air-conditioner fin comprises the rip cutting blade of installing in opposite directions up and down, and the two-end part of described rip cutting blade becomes arc structure, and the position that secondary repeats to cut on the rip cutting blade cutting edge has groove.
Its further technical scheme is:
The A/F of described groove is less than its degree of depth.
Technique effect of the present invention:
The rip cutting that the present invention is directed to existing straight knife shape cutting edge up and down cutter can't be avoided repeating to cut in single double jump action and deficiency that Burr Problem occurs is improved, the position of repeating to cut by secondary on the rip cutting blade facets has groove, make to repeat to cut in the single double jump action and avoided, thereby so that repeat to cut Burr Problem and solved.
Description of drawings
Fig. 1 is main TV structure figure of the present invention.
Fig. 2 is the partial enlarged drawing of I section among Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
Consult Fig. 1, Fig. 2, the present invention includes rip cutting blade 1, the two-end part of described rip cutting blade 1 becomes arc structure, and the position that secondary repeats to cut on rip cutting blade 1 cutting edge has groove 2, and the A/F of groove 2 is less than its degree of depth.
For the finned length requirement of odd number hole count, under the top slitter on the slit sub-die cope match-plate pattern and the rip cutting on the lower bolster cutter to cutting length adjustment behind correct position, also need to rely on the action of single double jump in the feeding process to realize, namely only send a step.Take step pitch as 25mm, the mould of two steppings is example, normal feeding step pitch is 50mm, the single-hop feeding namely only send a step to be 25mm.So, there is a material section secondary will occur and repeats to cut, after the position that secondary on the rip cutting blade facets repeats to cut has groove, then can effectively avoid repeating to cut, thereby the Burr Problem that repeats to cut is solved.
More than describing is explanation of the invention, is not that limited range of the present invention within protection scope of the present invention, can be done any type of modification referring to claim to the restriction of invention.
Claims (2)
1. the longitudinal knife chip architecture of an air-conditioner fin, comprise the rip cutting blade (1) of installing in opposite directions up and down, the two-end part of described rip cutting blade (1) becomes arc structure, it is characterized in that: the position that secondary repeats to cut on rip cutting blade (1) cutting edge has groove (2).
