Referring to fig. 1-4, the present invention provides a technical solution:

the utility model provides a plank formula die-cut cutting die with gradual change cutting edge, includes:

the wood substrate 1 is used for bearing a gradual change blade for stamping;

the stamping knife 2 is arranged on the stamping surface of the wood substrate 1; the punching knife 2 is a metal knife strip which is connected end to end and forms a closed loop shape, the knife edge of the punching knife 2 comprises an inner single-edge knife edge and an outer single-edge knife edge, and a V-shaped knife edge is arranged between the inner single-edge knife edge and the outer single-edge knife edge to form a gradual change knife edge;

the connecting assembly 3 is arranged at the joint of the head and the tail of the punching cutter 2 and is used for connecting the head and the tail of the punching cutter 2 in a closed-loop shape; the method comprises the steps that a hole is formed in the head end and the tail end of a metal cutter strip forming a closed loop in advance, a punching cutter 2 is fixed on the punching surface of a wood substrate 1, and a connecting component 3 is arranged at the head end and the tail end of the punching cutter 2 and used for fixing the head end and the tail end of the punching cutter 2 again;

wherein, the head end and the tail end of the punching cutter 2 are contacted, and the inner side and the outer side of the head end and the tail end of the punching cutter 2 are aligned. After the punching cutter 2 forms a closed loop shape, the head end and the tail end of the punching cutter are not overlapped, the thickness of the connecting position of the head end and the tail end is consistent with the thickness of other positions, and a punched product keeps good integrity. The problem of metal sword strip end to end department overlap together, increase the thickness of overlapping position, inconsistent with other position thickness, lead to the product that the punching press was come out can be lacked in overlapping position is solved.

Specifically, the connection assembly 3 includes:

a cross bar 303;

at least two insertion blocks 301 symmetrically arranged on the contact side of the transverse bar 303;

wherein, the inserting block 301 is arranged in the through hole 201 which is fixedly arranged at the head end and the tail end of the punching knife 2 in a penetrating way;

at least two groups of elastic sheets 302 are arranged at the plugging end of the plugging block 301.

The utility model discloses a set up horizontal bar 303, plug-in block 301 and shell fragment 302, set up through-hole 201 at the metal sword strip head and tail end that constitutes closed loop form in advance, the butt joint of metal sword strip head and tail end constitutes the die cutter 2 of closed loop form and fixes on wooden base plate 1 after, plug-in block 301 injects in the through-hole 201, shell fragment 302 contacts through-hole 201 earlier and gets into the end wall, shell fragment 302 is extruded to plug-in block 301 and gets into in the through-hole 201, stretch out from through-hole 201 exit end until plug-in block 301, horizontal bar 303 contact side laminating die cutter 2, shell fragment 302 is not being kick-backed after being extruded by through-hole 201 inside wall, support die cutter 2 through shell fragment 302, thereby will plug-in block 301 location in through-hole 201, make die cutter 2 head and tail end lie in being fixed basis of wooden base plate 1 once more and be positioned, ensure that die cutter 2 head and tail end connection is stable.

Further, the plug-in block 301 is composed of a cuboid and a trapezoid body, the cuboid is in sliding fit with the through hole 201, the tail end of the trapezoid body is located in the through hole 201, and the head end of the trapezoid body is located outside the through hole 201; the insertion block 301 is inserted into the through hole 201, the elastic sheet 302 firstly contacts the through hole 201 to enter the end wall, the elastic sheet 302 is extruded towards the side edge of the trapezoidal body of the insertion block 301, and the rectangular body is not influenced after the elastic sheet 302 is extruded to enter the through hole 201.

Wherein, a gap is reserved between the oblique edges at two sides of the trapezoid body and the inner side wall of the through hole 201. The gap is arranged so that when the plug block 301 is pulled out, a worker extrudes the elastic sheet 302 towards the side edge of the trapezoidal body of the plug block 301, and the elastic sheet 302 can smoothly enter the through hole 201.

Furthermore, each group of the elastic sheets 302 is provided with two elastic sheets 302, the two elastic sheets 302 are respectively and fixedly arranged at two sides of the head end of the trapezoid body, and each group of the elastic sheets 302 is splayed. The movable ends of the two elastic sheets 302 in each group respectively prop against the punching knife 2, and each group of the splayed elastic sheets 302 is equivalent to a triangle, so that the positioning effect is better.

The working principle is as follows: the through hole 201 is formed in advance in the head end and the tail end of the metal blade forming the closed-loop form, after the punching cutter 2 forming the closed-loop form by butting the head end and the tail end of the metal blade is fixed on the wood substrate 1, the insertion block 301 is inserted into the through hole 201, the elastic sheet 302 firstly contacts the through hole 201 to enter the end wall, the elastic sheet 302 is extruded to the trapezoidal side edge of the insertion block 301 until the insertion block 301 extends out of the outlet end of the through hole 201, the contact side of the cross bar 303 is attached to the punching cutter 2, the elastic sheet 302 is not extruded by the inner side wall of the through hole 201 and then rebounded, the movable ends of the two elastic sheets 302 of each group respectively abut against the punching cutter 2, and the insertion block 301 is positioned in the through hole 201.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
