The inner cutter (1) is composed of a cutter handle section (1a), a positioning section (1b) and a cutter edge section (1c). The outer cutter (2) is a cylinder, and the outer profile of the outer cutter (2) is composed of an upper cylindrical section and a lower outer cutter edge section (2a). The tool enables an operator to punch ultrathin soft rubber rings manually, saves design and manufacture cost of a special punching mold, and greatly reduces product cost.
Description
Technical field
The invention belongs to the Die cutting tool designing technique, relate to the instrument of the die-cut ultra-thin soft rubber ring of a kind of craft.
Background technology
At present, when die-cut ultra-thin soft rubber ring, need special-purpose die cutting die, on punch press, process.For the rubber ring of small lot, many kinds, manufacture and design special-purpose die cutting die and cause frock costly, increased product cost greatly.
Summary of the invention
The objective of the invention is: propose the instrument of the die-cut ultra-thin soft rubber ring of a kind of craft,, reduce product cost to save the expense that manufactures and designs of special-purpose die cutting die.
Technical scheme of the present invention is: a kind of rubber ring Die cutting tool is characterized in that it is made up of inner cutter 1 and outer cut 2; Inner cutter 1 is connected to form by handle of a knife section 1a, positioning section 1b and blade section 1c, and the outside diameter d 1 of positioning section 1b is less than the external diameter of handle of a knife section 1a, and the length of positioning section 1b is L 3; The outside diameter d of blade section 1c equals the internal diameter of processed rubber ring; The outside diameter d of blade section 1c has a central blind hole 1d less than the outside diameter d 1 of positioning section 1b in the lower surface of blade section 1c simultaneously, and it is the inner conical surface of 2 α that the inner port of this central blind hole 1d has a cone angle; Make the lower end of blade section 1c form cutting edge; α=15 °～20 °, the axial height of above-mentioned inner conical surface is not less than 2 times of rubber ring thickness, is positioned at handle of a knife section 1a at the bottom of the hole of said central blind hole 1d; A steam vent 1e who radially connects is arranged on the external cylindrical surface of handle of a knife section 1a, and steam vent 1e is communicated with central blind hole 1d; Outer cut 2 is cylinders; The endoporus of outer cut 2 is a stepped hole, outside diameter d 1 interference fits of the epimere diameter D1 of this stepped hole and inner cutter 1 positioning section 1b, and the epimere hole length of this stepped hole is L 3; The hypomere bore dia D of this stepped hole equals the external diameter of processed rubber ring; The outline of outer cut 2 is made up of the cylindrical section on top and the outer blade section 2a of bottom, and the outer surface of outer blade section 2a is that tapering is the taper seat of 2 α, makes the lower end of outer blade section 2a form cutting edge; Length from the lower end cutting edge of outer cut 2 to outer cut 2 upper surfaces is L4, and this length L 4 equals the length of the lower end cutting edge of inner cutter 1 to step end face between handle of a knife section 1a and the positioning section 1b.
Advantage of the present invention is: can die-cut by hand ultra-thin soft rubber ring, and the expense that manufactures and designs of having saved special-purpose die cutting die has reduced product cost significantly.Evidence, the ultra-thin soft rubber ring of certain type adopts the present invention to compare with special-purpose die cutting die, and product cost has reduced more than 90%.

The specific embodiment
Explain further details in the face of the present invention down.Referring to Fig. 1 to Fig. 3, a kind of rubber ring Die cutting tool is characterized in that; It is made up of inner cutter 1 and outer cut 2, and inner cutter 1 is connected to form by handle of a knife section 1a, positioning section 1b and blade section 1c, and the outside diameter d 1 of positioning section 1b is less than the external diameter of handle of a knife section 1a; The length of positioning section 1b is L 3, and the outside diameter d of blade section 1c equals the internal diameter of processed rubber ring, and the outside diameter d of blade section 1c is less than the outside diameter d 1 of positioning section 1b simultaneously; In the lower surface of blade section 1c a central blind hole 1d is arranged; It is the inner conical surface of 2 α that the inner port of this central blind hole 1d has a cone angle, makes the lower end of blade section 1c form cutting edge, α=20 °～25 °; The axial height of above-mentioned inner conical surface is not less than 2 times of rubber ring thickness; Be positioned at handle of a knife section 1a at the bottom of the hole of said central blind hole 1d, a steam vent 1e who radially connects is arranged on the external cylindrical surface of handle of a knife section 1a, steam vent 1e is communicated with central blind hole 1d; Outer cut 2 is cylinders; The endoporus of outer cut 2 is a stepped hole, outside diameter d 1 interference fits of the epimere diameter D1 of this stepped hole and inner cutter 1 positioning section 1b, and the epimere hole length of this stepped hole is L 3; The hypomere bore dia D of this stepped hole equals the external diameter of processed rubber ring; The outline of outer cut 2 is made up of the cylindrical section on top and the outer blade section 2a of bottom, and the outer surface of outer blade section 2a is that tapering is the taper seat of 2 α, makes the lower end of outer blade section 2a form cutting edge; Length from the lower end cutting edge of outer cut 2 to outer cut 2 upper surfaces is L4, and this length L 4 equals the length of the lower end cutting edge of inner cutter 1 to step end face between handle of a knife section 1a and the positioning section 1b.
Operation principle of the present invention is: Die cutting tool of the present invention is assembled into one with interior outer cut, thereby has improved production efficiency.The present invention has realized die-cut by hand, and above processed soft rubber material, ebonite board on the pad below processed soft rubber material utilizes hand hammer to knock the shank upper end uniformly and can accomplish the die-cut of rubber ring with Die cutting tool side.
Following table provides the parameter of 3 embodiment of the present invention, and unit is mm.
