Foreword

The level of mold production technology has become a country to

measure the level of manufacturing an important indicator.Because a large extent determine the mold product quality, efficiency and new product development capability.Approved by the State Council, from 1997 to 2000, more than 80 professional mold factory owned 70% VAT refund of preferential policies to support mold industry.All these have fully demonstrated the development of the State Council and state departments tooling industry attention and support.Revitalization and the development of China's mold industry, increasing people's attention and concern.\is the basis for industrial production technology equipment\has also been a consensus was reached.In electronics, automotive,

electrical,

electronics,

instruments,

appliances and communications products, 60% to 80% of the components rely on stamping.Possess with the mold workpiece high accuracy, high complexity, high consistency, high productivity and low consumption, other manufacturing methods can not match.Mold is \amplifier\with the mold the value of the final product, often die several times their value, on a hundred times

The 21st century, in the new situation of economic globalization, with capital, technology and labor market re-integration of equipment manufacturing in China after joining the WTO will become the world's equipment manufacturing base.In the modern manufacturing industry, no matter which industry, engineering equipment, are increasingly used to provide the products from the mold industry.In order to meet the user's high-precision mold manufacturing, short delivery time, the urgent demand low-cost, mold industry is extensive application of modern

advanced manufacturing technology to speed up the mold industry, technological progress, to meet the basic sectors of the mold process equipmenturgent needs.

(1) the design plan and product plans

The design plan and product plans one, subject name: Stator full

piece mold design 2, design the main technical parameters (the research direction): The stator lamination processing technology analysis, development of technology programs, and design stamping die.3, issue demands, the main task and the number refers to drawing specifications, the number of sheets, brochures words, etc.) 1. Analysis of process technology, development of technology programs.2. Set up access to more than 15 and topic-related literature.Graduate design specification should be 0.5-0.8 million words words.And 0.5-1 million for translation and printing operator (or translated 3000 characters) technical information relating to the above (along with the original), the content should be combined with topics.Product diagram as shown below (A)

(2) the part of the process of

Parts of the process of punching the shape of the stator and the management of the corner of symmetric over for mold.Fillet reduce the heat or the press office when the cracking phenomenon in the sharp corners.Edge angular position at the same time prevent excessive wear and tear.But the size of the stator laminations and high precision, complex shape, requirements flat surface, burr height is greater than 00.08mm. According to materials and then punch. Stamping parts process plan developed Option

One:

blanking,

punching

compound,

and

then

punching.Option Two: punching, blanking and blanking of continuous blanking.

(4) layout forms and cutting methods, materials utilization calculation

Part outline size Ф90, consider the convenience of a single row operation.From the reference \with the design\look-up table 3-10 have the side a = 2.0mm workpiece gap a1 = 1.3mm, Strip width b = 90 +2 a = (90 +4) mm = 94mm

Into the distance h = 90 + a1 = (90 +1.3) mm = 91.3mm

Use sheet metal specifications 1mmx830mmx1720mm, with horizontal, size strip cut 94mmx880mm.

Article Number n1 = 1720/94 = 18 条 I 28mm

Each number n2 = (830-1.3) / 91.3 = 9 个 than 7mm per plate number n3 = n1xn2 = 18x9 = 162 个

Punching area S = π (452 +232) - 13x6x12 = 3676.66mm2 material utilization ? = (162x3676.66/830x1720) x100% = 42%

. Based on the above calculation of the total force can be used 630KN Press.Selected nominal pressure 630KN JB21-63 slide 80 trips 65 trips / min maximum height of 320mm Die adjust the length of rod about 70mm around the table model 480 * 170 * handle the depth of pore size diameter of 50 * 70 motor power p = 5.5KW. Complete process card

. .(0.6-0.4) solution xTherefore, the die wall thickness = 1.5mm meet strength requirements.Notching a total of 12 punch, and punch (below) composed of one cylindrical tangent.Impulse hole punch by step structure, in order to enhance its strength and stiffness, is the standard form of round one punch.Circular edge of the hole punch and die (below), can be used to manufacture general machining.Other

Working parts of the edge part of the cutting wire are used, can guarantee the dimensional accuracy of parts, and reduce the workload
