The invention discloses a machining method for a die-cutting roller. The machining method comprises the step that the die-cutting roller is machined. The die-cutting roller comprises a roller body. A cutter drum and a cutter part are installed on the periphery of the roller body in an embedded mode. The roller body is provided with grooves. The cutter drum is provided with insert blocks and made of hard alloy materials. The machining steps for the die-cutting roller comprise that A, the roller body is machined, specifically, a cutter is made, and an outer circle shaft shoulder and the grooves of the roller body are turned out in a numerical control machining center; B, the insert blocks are made, specifically, a silica gel printing mold is made of soft silica gel, and a blank used for making the hard-alloy insert blocks is obtained through sintering according to the silica gel printing mold; C, the cutter drum is machined, specifically, hard alloy powder materials are sintered to form a cutter drum blank and the cutter part in one time, and then the cutter drum blank and the cutter part are subjected to combined sintering together with the insert block blank; and D, assembly is conducted, specifically, the cutter drum is inserted into the roller body. Compared with the prior art, through the machining method, the problems that the manufacturing cost is high, using is inconvenient, and resources are wasted due to an existing machining method for a die-cutting roller can be solved.

Description

The processing method of die cutting roller

Technical field

The present invention relates to carbide alloy and cut roller processing equipment technical field, especially a kind of processing method for rolls such as roller cut paper urine pants, hygenic towelettes.

Background technology

The existing device for roller cut paper urine pants, hygenic towelette etc., generally all comprise two rolls up and down driven by actuating unit to form, the roll of top is provided with shaping cutting knife, the roll of below is provided with the cutting knife rolled, the raw material such as paper diaper, hygenic towelette roller between upper and lower two rolls is cut, and extrudes stamp while cutting out edge.But the cutting knife of shaping cutting knife and annular knurl is all generally make one with roll Hardmetal materials, like this in order to produce the product of multiple specification, need to manufacture the cutting knife of many sleeve formings and the cutting knife size difference cover roll of annular knurl, manufacturing cost is high, and need to change a whole set of roll when changing product specification, it is very inconvenient to use; In addition, if after the cutting blade abrasion of shaping cutting knife and annular knurl, whole roll is all scrapped, and causes the waste of material resources.Thus need to design and a kind ofly can change and ensure to combine the roll be closely convenient for changing again, and processing method, to reduce material cost and the raising working (machining) efficiency of roll.

Summary of the invention

Problem to be solved by this invention is to provide a kind of processing method of die cutting roller, high with the processing method manufacturing cost solving existing die cutting roller, uses inconvenience, causes the problem of the wasting of resources.

In order to solve the problem, technical scheme of the present invention is: the processing method of this die cutting roller comprises a kind of die cutting roller of processing; Described die cutting roller comprises roll body, described roll body is outer is embedded with cutting knife cylinder in one week, described cutting knife cylinder is provided with cutting knife portion, described roll body is provided with at least two place's grooves, described groove is square in what tilt on radial section, and described groove comprises Vertical dimension hypomere, is tilted to hypomere and translation section on axial cross section; Described cutting knife cylinder inner edge is provided with the abaculus of protrusion; Described cutting knife cylinder is that Hardmetal materials is made; Described cutting knife portion is roller cutoff edge oral area;

Its procedure of processing comprises:

A processes roll body: polish cutter, the cutting edge level of described cutter with sintering hard alloy material; The bar of No. 20 steel or No. 45 steel is fixed on numerical control machining center, first to get on the bus out roll body cylindrical at bar, the shaft shoulder, then the groove replacing with that described cutter vehicle goes out roll body;

B makes abaculus: embed completely in the groove of roll body with soft silica gel, take out after compacting, and mark datum line, obtains silica gel die, sinters out making carbide alloy abaculus blank by silica gel die;

C processes cutting knife cylinder: with carbide alloy powder disposable sinter out cutting knife cylinder blank and on draw together cutting knife portion, more together carry out combined sintering with abaculus blank, formation cutting knife cylinder, with the datum line of each abaculus blank for benchmark; Cutting knife portion repaiied by mill;

D assembles: cutting knife cylinder is inserted roll body, and slightly rotates, make the abaculus of cutting knife cylinder embed roll body completely.

Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:

1, the die cutting roller processed of the processing method of this die cutting roller, the mode adopting roll body and cutting knife part to be provided separately, can facilitate cutting knife or annular knurl according to the product of different size size; Cutting knife and annular knurl are designed to cylinder, and cylinder is combined with roll body again, solve independent large in conjunction with installation and debugging difficulty with roll body because cutting knife installation accuracy is high, affect the problem of crudy; The carbide alloy manufacture of cutting knife cylinder, roll body can with lower No. 45 steel makings of expense, can on the basis not affecting processing technology conservation, reduce material cost; Special groove and abaculus, make to combine between roll body and cutting knife cylinder better;

2, this method manufactures cutter numerical control machining center processing roll body and the groove of machined grooves, ensure that machining accuracy; With silica gel die assist manufacture abaculus, then with cutting knife cylinder together combined sintering, ensure that in machining accuracy ground foundation, include again the quality of fit of abaculus and groove.

Detailed description of the invention

Below in conjunction with accompanying drawing, the embodiment of the present invention is described in further detail:

The processing method of this die cutting roller comprises a kind of die cutting roller of processing, die cutting roller as shown in Figure 1, Figure 2, Figure 3 shows, comprise roll body 2, roll body 2 is outer is embedded with cutting knife cylinder 3 in one week, cutting knife cylinder 3 is provided with cutting knife portion 3-1, here cutting knife portion 3-1 is roller cutoff edge oral area, and the mode adopting roll body and cutting knife part to be provided separately, can facilitate cutting knife according to the product of different size size; Cutting knife is designed to cylinder, and cylinder is combined with roll body again, solves independent large in conjunction with installation and debugging difficulty with roll body because cutting knife installation accuracy is high, affects the problem of crudy.Roll body 2 is provided with groove 2-1, cutting knife cylinder 3 inner edge is equipped with the abaculus of protrusion, cutting knife cylinder 3 is combined with roll body 2 by their abaculus and the groove 2-1 of roll body 2, the two ends shaft shoulder of cutting knife cylinder 3 two ends and roll body 2 is provided with hubcap 1, and by screw-tightened, with ensure between cylinder and roll body are axially in conjunction with tight.Cutting knife cylinder 3 is made for Hardmetal materials, and roll body 2 can with lower No. 45 steel makings of expense, can on the basis not affecting processing technology conservation, reduce material cost.Groove 2-1 is square in what tilt on radial section, and as Fig. 1, groove 2-1 comprises Vertical dimension hypomere 2-1-1, is tilted to hypomere 2-1-2 and translation section 2-1-3, as Fig. 3 on axial cross section.The structure of the abaculus of cutting knife cylinder 3 is corresponding to groove 2-1.
