Abstract
The utility model discloses a knife casing for cutting sheets, which comprises a left knife casing and a right knife casing. The left knife casing and the right knife casing are connected through a knife ring; the left knife casing comprises a cylindrical section and a clearance section; a filleted corner structure is formed on an edge of an end face of the cylindrical section connected with the clearance section; the clearance section is connected with the knife ring; and a bottom knife is arranged below the knife ring. By arranging the filleted corner structure on the edge of the end face of the cylindrical section and the clearance section, the knife casing for cutting sheets can effectively relieve the phenomenon that traces or wrinkles are formed on the edges after PI sheets are cut, and even eliminate the traces or wrinkles completely. Therefore, the influence on subsequent processing of the PI sheets is reduced, and the product quality is improved. The knife casing for cutting sheets is simple in structure, is improved on the basis of the conventional knife casing, is applied to cutting other sheets besides the PI sheets, and is wider in application range.
Description
Technical field
The utility model relates to flexible circuit plate substrate manufacture field, particularly a kind of broach shell that is used for the sheet material shearing.
Background technology
In the processing of flexible circuit plate substrate, according to actual needs, all must shear usually the sheet material of PI (polyimides).The broach shell that is usually used in the shearing of PI sheet material generally is made of left broach shell and right broach shell, connects by the cutter ring between the left and right broach shell, and the broach shell rotation drives in the proal process of PI sheet material, by the bed plate of being located at cutter ring below the PI sheet material is sheared.But because in the broach shell commonly used at present, left side broach shell is full straight-tube shape structure, the end face that left side broach shell and cutter ring join is a rounded bottom surface, and its end surface side edge is sharp limit, the end face outside any changeover portion also useless or empty avoiding section, after this just makes that the PI sheet material is sheared, its edge stays impression or wrinkle easily, and especially when the sheet material that is sheared was hard, this phenomenon was more obvious, this just influences the following process of material easily, and then influences product quality.
The utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of broach shell that sheet material is sheared that is used for is provided, and can effectively improve the phenomenon that stays impression or wrinkle after sheet material is sheared easily, guarantees product quality.
The technical solution of the utility model is: a kind of broach shell that is used for the sheet material shearing, comprise left broach shell and right broach shell, connect by the cutter ring between left side broach shell and the right broach shell, described left broach shell comprises cylindrical section and empty avoiding section, the end surface side that cylindrical section and empty avoiding section are joined is along being fillet structure, the empty avoiding section is connected with the cutter ring, and cutter ring below is provided with bed plate.
The radius of described fillet is 3～5mm.
The cylindrical section external diameter of described left broach shell is 80mm.
The empty avoiding section external diameter of described left broach shell is 70mm, and the empty avoiding segment length is 3～6mm.
When originally being used for the broach shell use of sheet material shearing, its operation principle is: left broach shell and right broach shell drive the PI sheet material and transport forward under the drive of its axis of rolling, transport in the process at it, by bed plate the PI sheet material are sheared; Because left broach shell and cutter ring joint are provided with the empty avoiding section, and its edge is a fillet structure on the end face that cylindrical section and empty avoiding section are joined, reduced pressure in the empty avoiding section when making PI sheet material slitting, make the PI sheet material from reducing by fillet structure simultaneously with the intersection point of cylindrical section angle to the stress point of bed plate, so the stressed of PI sheet material also just reduces, the impression that the PI sheet material is sheared its edge, back can alleviate greatly, even eliminates.
The utility model has following beneficial effect with respect to prior art:
Originally the broach shell that is used for the sheet material shearing is provided with fillet structure and empty avoiding section by the end surface side edge at its cylindrical section, can effectively alleviate the PI sheet material be sheared the back its edge leave impression or wrinkle phenomenon, even impression or wrinkle are eliminated fully, thereby reduce influence, improve the quality of products PI sheet material following process.
Originally the broach shell that is used for the sheet material shearing is simple in structure, improves getting final product on the basis of original broach shell.Simultaneously, the broach shell that originally is used for the sheet material shearing also is applicable to the shearing of other kind based sheet except being used for the shearing of PI sheet material, and its scope of application is wider.
Description of drawings
Fig. 1 is the structural representation that originally is used for the broach shell of sheet material shearing.
Fig. 2 is the structural representation that originally is used for the left broach shell of broach shell of sheet material shearing.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but embodiment of the present utility model is not limited thereto.
Embodiment
A kind of broach shell that is used for the sheet material shearing of present embodiment, its structure as shown in Figure 1, comprise left broach shell 1 and right broach shell 2, connect by cutter ring 3 between left side broach shell 1 and the right broach shell 2, the structure of wherein left broach shell 1 comprises cylindrical section 4 and empty avoiding section 5 as shown in Figure 2, and cylindrical section 4 is fillet structure with the end surface side that empty avoiding section 5 is joined along 6, empty avoiding section 5 is connected with cutter ring 3, and cutter ring 3 belows are provided with bed plate 7.
In the above-mentioned broach shell structure, the end surface side of left broach shell 1 is 3～5mm along 6 radius of corner.
Empty avoiding section 5 external diameters of left side broach shell 1 are 70mm, and empty avoiding section 5 length are 3～6mm.
When originally being used for the broach shell use of sheet material shearing, its operation principle is: left broach shell 1 and right broach shell 2 drive the PI sheet material and transport forward under the drive of its axis of rolling, transport in the process at it, shear by 7 pairs of PI sheet materials of bed plate; Because left broach shell 1 is provided with empty avoiding section 5 with the joint of cutter ring 3, and its edge is a fillet structure on the end face that cylindrical section 4 and empty avoiding section 5 are joined, reduced pressure in the empty avoiding section when making PI sheet material slitting, make the PI sheet material from reducing by fillet structure simultaneously with the intersection point of cylindrical section 4 angle to the stress point of bed plate 7, so the stressed of PI sheet material also just reduces, the impression that the PI sheet material is sheared its edge, back can alleviate greatly, even eliminates.
As mentioned above, just can realize the utility model preferably, the foregoing description is preferred embodiment of the present utility model only, is not to be used for limiting practical range of the present utility model; Be that all equalizations of being done according to the utility model content change and modification, all contained by the utility model claim scope required for protection.
