CN104096743A - Method for punching nested row materials - Google Patents

Abstract

The invention discloses a method for punching nested row materials. The method includes steps of 1), laying different products to form a plurality of columns in an insertion manner according to the sizes of the different products, to be more specific, inserting a row of products with different sizes in spaces among waste materials between the two original rows of products required to be punched, and then punching the products in a progressive die punching mode; 2), punching waste materials in the edge columns or waste materials among the products in the progressive die punching mode to obtain corresponding wafers. The method has the advantages that the progressive die mode is adopted, the products in the multiple columns are punched, and accordingly the production efficiency and the material utilization rate are high.

Description

Cut out a piece of cloth in a way with the minimum material to make two or more articles of clothing discharge blanking method

Technical field

The present invention relates to a kind of discharge blanking method of cutting out a piece of cloth in a way with the minimum material to make two or more articles of clothing, belong to industrial motor blanking sheet and cut out a piece of cloth in a way with the minimum material to make two or more articles of clothing technical field.

Background technology

Industrial motor punching at present adopts single punch-die stamping-out, production efficiency is low, and single punch-die can only adopt single-row marker method stamping-out, for the circular punching of industrial motor, stock utilization is very low, along with the development in market, competition grows in intensity, and how reducing material cost is the difficult problem that each enterprise must capture.

Summary of the invention

For solve industrial motor produce at present in, production efficiency is low, stock utilization is low problem, the present invention proposes a kind of save material, enhance productivity cut out a piece of cloth in a way with the minimum material to make two or more articles of clothing discharge blanking method.

The discharge blanking method of cutting out a piece of cloth in a way with the minimum material to make two or more articles of clothing of the present invention, comprises the following steps:

1) according to different product specification, carry out multiple row and intert and to arrange, between the waste material originally needing between two row products of stamping-out, interting after the product of different size of another row, then adopting progressive die stamping-out mode to carry out stamping-out;

2) in the waste material or the waste material between product of edge one row, adopt the corresponding disk of progressive die stamping-out mode stamping-out.

The invention has the beneficial effects as follows: adopt progressive die mode, and also multiple row stamping-out, production efficiency is high, and stock utilization is high.

Accompanying drawing explanation

Fig. 1 the present invention cuts out a piece of cloth in a way with the minimum material to make two or more articles of clothing discharge stamping-out schematic diagram.

The existing conventional straight line itemize process schematic representation of Fig. 2.

The specific embodiment

Below in conjunction with accompanying drawing, further illustrate the present invention

With reference to accompanying drawing:

Embodiment 1 be take the 1200mm of steel mill raw material stamping-out as example (accompanying drawing 1 mark explanation: axis hole 1, rotor blanking 2, stator blanking 3, big circular slice 4, sequin 5).

The 1200mm of steel mill raw material directly carry out discharge stamping-out, are divided into four row stamping-outs, first stamping-out axis hole 1 in every row, then stamping-out rotor blanking 2, last stamping-out stator blanking 3.At 1200mm billot two leftover bits and pieces of material place stamping-out big circular slices 4, stamping-out sequin 5 in the waste material between stator blanking 3.Namely, in stamping-out major product rotor blanking 2 and stator blanking 3, unnecessary billot can also be made full use of, go out the big circular slice 4 and the sequin 5 that can be used for industrial motor small dimension product, improve stock utilization.

Embodiment 2 be take industrial motor Y2-200 as example, (product external diameter 327mm, the wide 332mm of the required coiled strip material of progressive die, the raw material width 1200mm that dispatches from the factory of steel mill.) 1～2 the invention will be further described by reference to the accompanying drawings.

The wide 332mm of the coiled strip of straight line shown in Fig. 2 material, 1200mm straight line slitting sawing sheet can obtain 3 of the straight line coiled strips of the wide 332mm of material, removes the required both sides of slitting each 2mm of overlap, finally the wide 200mm of residue material.As need obtain 4 332mm, expect wide coiled strip, the coiled strip that Xu Xiang steel mill orders 1332mm (332*4+4=1332), has improved production cost greatly.

Shown in Fig. 1, cut out a piece of cloth in a way with the minimum material to make two or more articles of clothing the 1200mm of the Liao Kuanwei steel mill raw material of discharge stamping-out, by multiple row, intert the mode of discharge and improve stock utilization, can stamping-out the product of 4 row Y2-200, compare nearly 11% (132/1200=11%) of raising stock utilization with tradition and not only reduced production cost, Ye Gei enterprise brings considerable economic results in society.

The present invention is applied to progressive die production in addition, and stamping-out speed can reach 80-100 beat/min, than 30 beats/min of conventional single punch-die stamping-out speed, fast nearly 3 times, and a stamping-out can go out four row products, both are added, and the efficiency of the technology of the present invention than the fast 10-12 of single punch-die doubly.

Content described in this description embodiment is only enumerating the way of realization of inventive concept; protection scope of the present invention should not be regarded as only limiting to the concrete form that embodiment states, protection scope of the present invention also comprises that those skilled in the art conceive the equivalent technologies means that can expect according to the present invention.

Claims (1)

1. cut out a piece of cloth in a way with the minimum material to make two or more articles of clothing discharge blanking method, comprise the following steps:
