Abstract
The longitudinal knife of a kind of air-conditioner fin die of disclosure, including longitudinal knife, the blade of described longitudinal knife has serrate slot, and the two ends of blade are provided with inclined-plane, the width of described serrate slot is 0.2～0.4mm, and its degree of depth is 0.6～1.5mm, described serrate slot includes being positioned at multiple first serrate slots of blade middle, being positioned at multiple second serrate slots on blade left end inclined-plane and be positioned at multiple 3rd serrate slots on blade right-hand member inclined-plane, described first serrate slot is vertically arranged, described second serrate slot and the 3rd serrate slot are arranged symmetrically with, and slope inwardly。The longitudinal knife simple in construction of described air-conditioner fin die, it is easily achieved, it is by offering serrate slot in the middle of the blade of longitudinal knife and inclined-plane, two ends place, utilize the cross sections on serrate slot, the burr produced is carried out corresponding transverse cuts by the longitudinally cutting process of longitudinal knife and tears, make burr and product separation, be effectively increased product quality。
Description
Technical field
The present invention relates to the longitudinal knife of a kind of air-conditioner fin die。
Background technology
Air-conditioner fin is the fin in air-conditioning for heat exchange, and most air-conditioner fin material is aluminum or copper。Air-conditioner fin die is the high-accuracy cold punching progressive die of a kind of special production air-conditioner fin。At present, in air-conditioner fin die, it is usually utilization slit sub-die in a mold is installed to complete the cutting of product billot。In the continuous cutting process to material, when especially having feeding stroke to change, the air-conditioner fin that conventional longitudinal knife cuts out has burr different in size, thus leveraging outward appearance and the quality of air-conditioner fin。
Summary of the invention
Present invention aims to the problems referred to above, it is provided that the longitudinal knife of a kind of air-conditioner fin die, to solve to adopt the air-conditioner fin that the longitudinal knife of existing air-conditioner fin die cuts out to have burr different in size, the problem affecting product quality。
It is an object of the invention to be achieved through the following technical solutions:
A kind of longitudinal knife of air-conditioner fin die, including longitudinal knife, the blade of described longitudinal knife has serrate slot, and the two ends of blade are provided with inclined-plane, the width of described serrate slot is 0.2～0.4mm, and its degree of depth is 0.6～1.5mm, described serrate slot includes being positioned at multiple first serrate slots of blade middle, being positioned at multiple second serrate slots on blade left end inclined-plane and be positioned at multiple 3rd serrate slots on blade right-hand member inclined-plane, described first serrate slot is vertically arranged, described second serrate slot and the 3rd serrate slot are arranged symmetrically with, and slope inwardly。
Further, described longitudinal knife has installing hole。
Further, described the first serrate slot, the second serrate slot and the 3rd serrate slot are 3。
Further, the width of described serrate slot is 0.2mm, and the degree of depth of serrate slot is 0.9mm。
Beneficial effects of the present invention is, the longitudinal knife simple in construction of described air-conditioner fin die, it is easily achieved, it is by offering serrate slot in the middle of the blade of longitudinal knife and inclined-plane, two ends place, utilize the cross sections on serrate slot, the burr produced carried out corresponding transverse cuts by the longitudinally cutting process of longitudinal knife and tears, making burr and product separation, be effectively increased product quality。

1, longitudinal knife；2, installing hole；3, the second serrate slot；4, blade；5, the first serrate slot；6, the 3rd serrate slot。
Detailed description of the invention
Technical scheme is further illustrated below in conjunction with accompanying drawing and by detailed description of the invention。
Refer to shown in Fig. 1, Fig. 1 is the structural representation of the longitudinal knife of a kind of air-conditioner fin die of the present invention；In the present embodiment, a kind of longitudinal knife of air-conditioner fin die, including longitudinal knife 1, described longitudinal knife 1 has installing hole 2, it is easily installed, the blade 4 of longitudinal knife 1 has serrate slot, and the two ends of blade 4 are provided with inclined-plane, the width of described serrate slot is 0.2mm, and its degree of depth is 0.9mm, described serrate slot includes three the first serrate slots 5 being positioned at blade middle, it is positioned at three second serrate slots 3 on blade 4 left end inclined-plane and is positioned at three the 3rd serrate slots 6 on blade 4 right-hand member inclined-plane, described first serrate slot 5 is vertically arranged, described second serrate slot 3 and the 3rd serrate slot 6 are arranged symmetrically with, and slope inwardly。
The present invention is by offering serrate slot in the middle of the blade 4 of longitudinal knife 1 and inclined-plane, two ends place, utilize the cross sections on serrate slot, the burr produced is carried out corresponding transverse cuts by the longitudinally cutting process of longitudinal knife 1 and tears, make burr and product separation, effectively solve to adopt the air-conditioner fin that the longitudinal knife of conventional air-conditioning fin die cuts out to have burr different in size, the problem affecting product quality。
Above example simply elaborates ultimate principle and the characteristic of the present invention; the present invention is not limited by above-described embodiment; without departing from the spirit and scope of the present invention, the present invention also has various change and change, and these changes and change both fall within the claimed scope of the invention。Claimed scope is defined by appending claims and equivalent thereof。
