Abstract
The utility model discloses a fin slitting and splitting structure, which comprises a group of slitting cutters which are arranged in parallel, a supporting plate for supporting a fin, and a pressing plate for allowing the fin to fall, wherein the supporting plate is of a plane structure before a fin slitting cutter carries out splitting, and the matched surface of the pressing plate is also of a plane structure; the supporting plate is provided with a groove structure corresponding to each fin after the fin slitting cutter carries out splitting, and the pressing plate is provided with an inclined plane structure matched with the groove structure. The problem that a single fin easily generates burrs when the fin is repeatedly cut is solved, the die structure is simple, and the amount of change is small. The fin slitting and splitting structure can be widely applied to the field of fin stamping dies.
Description
Technical field
The utility model relates to fin stamping mould field, especially relates to a kind of fin slitting striping structure.
Background technology
In existing air-conditioning exchanging air fin stamping mould, in order to ensure rip cutting, cut fin completely and have certain mistake amount of cutting, now just there will be part fin to be repeated to cut the situation of twice.And in multistep progressive die tool due to the requirement of product specification, when feeding, there will be the conversion of odd number charging and even numbers charging, the situation that repeats to cut in this process can be more outstanding.Because material has certain shake in mould, there is deviation and cause the generation of burr, affect the quality of production in the position that makes to be cut for twice.
Utility model content
The purpose of this utility model is to provide a kind of fin slitting striping structure, solves the problem that causes fin edges generation burr in existing fin slitting striping operation because repeating incisal guide.
The utility model solves the technical scheme that its technical problem adopts: a kind of fin slitting striping structure, comprises the one group of rip cutting cutter be arrangeding in parallel, for supporting the retainer plate of fin and making the holding pad of fin declivity; Described retainer plate was planar structure before fin rip cutting cutter itemize, and the mating surface of described holding pad is also planar structure; Retainer plate corresponding every fin after fin rip cutting cutter itemize is provided with groove structure, and described holding pad is provided with the ramp structure coordinating with groove structure.
Preferably, between described adjacent two groove structures, be provided with the boss structure of transition.
For wall scroll fin is opened, the width of all groove structures is less than the width of wall scroll fin.
Smooth and easy for wall scroll fin is separated, the top of the corresponding boss structure of described holding pad is provided with the groove of stepping down.
The beneficial effects of the utility model: be provided with a groove structure by retainer plate corresponding every fin after fin rip cutting cutter itemize, wall scroll fin is under the effect of retainer plate groove structure and holding pad ramp structure, adjacent two fins are opened in incision, adjacent two fins repeat to cut part at fin rip cutting cutter and produce certain gap, fin rip cutting cutter can not switched on the limit of wall scroll fin again, prevent from that fin rip cutting cutter from repeating to switch on the limit of wall scroll fin to produce burr.The width of described groove structure is less than the width of wall scroll fin, and a wall scroll fin part is ridden on boss structure, and another part drops in groove structure, makes to separate more thorough.The described groove assurance fin of stepping down can not interfered with holding pad when falling into groove structure, makes to separate more smooth and easy.
Below with reference to drawings and Examples, the utility model is described in detail.
Accompanying drawing explanation
Fig. 1 is the cutaway view at the utility model groove structure place.
Fig. 2 is the finned cutaway view of the utility model.
Fig. 3 is the structural representation along rip cutting tool orientation.
The specific embodiment
Embodiment, as shown in Figures 1 to 3, a kind of fin slitting striping structure, comprises the one group of rip cutting cutter 1 be arrangeding in parallel, for supporting the retainer plate 2 and the holding pad 3 that makes fin 4 declivities of fin 4; Described retainer plate 2 was planar structure before fin rip cutting cutter itemize, and the mating surface of described holding pad 3 is also planar structure; Retainer plate 2 corresponding every fin 4 after fin rip cutting cutter itemize is provided with groove structure 5, and described holding pad 3 is provided with the ramp structure 6 coordinating with groove structure 5.5 of adjacent two groove structures are provided with the boss structure 7 of transition.The width of all groove structures 5 is less than the width of wall scroll fin.
For making separation more smooth and easy, the top of the corresponding boss structure 7 of described holding pad 3 is provided with the groove 8 of stepping down.By one group of fin isolating construction being set after fin rip cutting cutter itemize, prevent that repeating to cut part fin produces burr.
Claims (4)
