Abstract

The invention relates to a multi-direction step-by-step tridimensional punching method of IML products and a punching mould thereof, which is characterized in that a punching mould combing a direct punching mould and a lateral punching mould is adopted to dimensionally punch the cavern shapes and edge contours of IML product located on different surfaces step by step; the punching mould comprises an upper mould which comprises a punch (straight punching head) and a lower mould which comprises a die and air cylinder side cut assemblies; the punch of the upper mould and the die of the lower mould form a straight punching mode; the side wall of the die and four groups of air cylinder side cut assemblies of the lower mould form a side punching mode; a multidirectional step-by-step dimensional method is adopted to decompose the punching of the IML product with complex structure and shape into one-step punching with simpler shape, the power of one-step punching of side faces is provided by a straight air cylinder, thereby ensuring the quality and stability of quenching; in addition, the punching method has simple operation and accurate production orientation, the qualification rate can be above 90%, therefore, the method is applicable to large-scale batch production.

Description

A kind of IML product multi-faceted, step by step, three-dimensional method for die cutting and die cutting die thereof

Technical field

The present invention relates to three-dimensional IML product method for die cutting, particularly be used for processed complex structure I ML product workpiece and the thicker product workpiece of punched material a kind of IML product multi-faceted, step by step, three-dimensional method for die cutting and die cutting die thereof.

Background technology

Labyrinth IML product workpiece and the thicker IML product of material workpiece die-cut; requirement to die cutting die is very high; when porose or wall thickness is greater than 0.4mm when punched product sidewall; die-cut difficulty can increase a lot; with existing when flinging this problem of technical finesse; the common appearance requirement that can can't go out the hole on the sidewall or can't satisfy thicker IML product owing to the section broad after die-cut; therefore; adopting new designing and developing is pressing for of producing, and the clicking technique and the method for the processing of labyrinth (for example: sidewall is porose) IML product have very big innovation and development space.

Summary of the invention

Purpose of the present invention is exactly for overcoming the deficiencies in the prior art, at existing fling technology can't go out on the punched product sidewall the hole or because the section broad after die-cut and can't satisfy the problem of the appearance requirement of thicker IML product, provide a kind of from multi-faceted, step by step, the method for three-dimensional die-cut labyrinth IML product and thicker IML product.

The present invention has thoroughly overturned cold-punching mould can only vertically die-cut theory, can go out complicated void shape and the side (sidewall) on the sidewall in order to realize a mold, can go out the shape hole of product surface again, through experiment, some cylinders, oil cylinder technology on the present frame for movement have been merged, finally our success combines local technology that flings and the technology that adopts the slide block of air cylinder structure mechanically to carry out side blow, developed the side-cutting mould tool, thus realized multi-faceted, step by step, three-dimensional method for die cutting.

Technical scheme provided by the invention be achieved in that a kind of IML product multi-faceted, step by step, three-dimensional method for die cutting, it is characterized in that, adopt a kind of die cutting die that flings pattern and the combination of side blow pattern, the IML product is positioned at the void shape of different surfaces and edge contour, and to carry out substep three-dimensional die-cut;

Described die cutting die is made up of part of the upper die and part of the lower die, and the part of the upper die comprises punch (fling head), and the part of the lower die comprises that die and cylinder power side cut assembly; Form the pattern that flings between the punch of part of the upper die and the die of part of the lower die; The die sidewall of part of the lower die and four groups of cylinder power sides are cut and are formed the side blow pattern between the assembly;

Cylinder power side is cut assembly and mainly is made of cylinder, piston rod, connector, take-up housing and slider head (side blow head), the cylinder piston piston rod, piston rod connects first end, the connector other end connects take-up housing one end with the curved surface sliding matching mode, the fixing slider head (side blow head) in the end of the take-up housing other end

The centre, plane processes the centre respectively and becomes groove shapes with four limits on the part of the lower die lower bolster of die cutting die, and middle negative area is die fixedly, and its four limits negative area is as the chute of four take-up housings; The corresponding respectively both sides, four chute upper edges that are fixed on lower bolster of four pairs of briquettings are arranged, and each is pressed in two edges, a take-up housing top to briquetting, plays slide rail and positioning action, and briquetting and take-up housing are slidingly matched;

Described IML product multi-faceted, step by step, three-dimensional method for die cutting comprises the steps:

(1) pattern that flings of startup die cutting die, punch (flinging head) punching stroke is opposite to the die-cut hole of three-dimensional IML product surface to be processed on the die from top to bottom;

(2) when the punch of die cutting die is positioned at the low level of punching stroke, the IML film that punch is opposite on the die keeps compaction state, stops for 3 seconds;

(3) start the cylinder valve switch in during this period, four cylinders on the die cutting die part of the lower die are moved simultaneously, the slider head (side blow head) that cylinder power side is cut assembly carries out the complicated shape or the hole of the IML product side on the die-cut die.

Use method for die cutting multi-direction, that substep is three-dimensional, be die-cut the decomposition with labyrinth shape IML product, the single step of resolving into fairly simple shape is die-cut, and the die-cut whole straight line cylinders that used of the single step of side provide power, has guaranteed die-cut quality and stability.And this kind method for die cutting processing ease, product orientation is accurate, and qualification rate can reach more than 90%, is fit to the needs of large-scale production in enormous quantities.
