Multitask of plug reed nicety class is designed into the model

5-0.

1Y, this material has good flexibility and fatigue resistance. Through be analysed to the craft of reed spare parts and be being calculated, decision design is made 150 strong second / precision of Min, dimension is 0.

Precision of 01mm, step pitch is 0.

The high accuracy multitask of 006mm class receives a standard. Of spare parts of 2 scale reed spread out graph and platoon master drawing to spread out dimension to be a basis with product figure, use the neutral line when bending changeless principle and geometric principle computation are departmental one-tenth size. Develop measure the requirement is very accurate, it should make sure material reachs the size that product blueprint asks after bending for many times. Makings send direction the step pitch that dimension of the broadest outline increases proper technology to built an edge to determine a pattern, the dimension of the broadest outline that after the spare parts spreads out, goes up along feed direction is 5.

75mm, craft takes a side for 2.

25mm, affirmatory step pitch is 8mm. Step pitch and spread out a graph to decide each develop flotsam punch measure jointly. Graph the 2 platoon master drawing that are a mould, it is having crucial effect to mould design, it is the key with whole deputy successful pattern. By the graph 2 knowable, the idle station of the mould is 16, active worker worker 22, total industry it is 38. Be versed in effectively a following: ? Couple Piao come on Huan of humorous excusing ㄎ lives? of humorous of extensive of の of post Yu of T instruct  assures fixed position precision, strong side edge is rough location, to fixed position aperture ② of; of the fixed position that it is essence of life guides; ③ guides to flotsam A; ④ D of strong flotsam of ⑦ of C; of strong flotsam of ⑥ of B; of; ⑤ strong flotsam and guide head of ⑨ of; of mouth of horn of ministry of; ⑧ pressure head, crushing thorn. Main part designs 3 patterns (1) mould bases uses mould bases of ball of 4 guide pillar, on, next pattern plate use 45 steel, move qualitative hardness 26 ～ 30HRC. The treatment precision of mould bases uses Ⅰ class precision, pattern plate ply is 40mm on, next pattern plate ply are 45mm. (The parallelism control of all 2) pattern plate is in 300:0.

02 less than, verticality is in 0.

015mm less than, exterior surface roughness is Ra =0.

M of 4 μ . (3) punch is designed. Big punch uses direct formula, small punch is used set a fixed protection, in order to increase its intensity and stiffness, material chooses Cr12 steel, quench hardness 55 ～ 58HRC, punch uses small pressing plate to secure. (4) sunken model uses cent piece to set sunken pattern plate in, is its advantage: ?  of hair on the neck of a pig of besmear of suddenly of の of Bei of じ of Xi makeup V vases Ji tuft whoop ② of? of  of  magpie bursa solved heat treatment to be out of shape problem; ③ each model aperture mold insert is machined alone, facilitate make, adjust and maintain, will not discard as useless because of some aperture damages and making make a sunken pattern plate; ④ raises ⑤ of; of service life of whole deputy pattern to be divided into small mold insert, facilitate with nicety Bench Machine Tool, special machine tool is machined. Sunken model mold insert and fits tolerance of sunken pattern plate take ± 0.

01mm. Load, take out convenient, assure precision, each model aperture sunken model is set piece pin by guide plate. To cut type aperture sunken model mold insert uses 6CrNiMnSiMoV of high grade alloy steel, abbreviation GD steel, heat treatment hardness 58 ～ 63HRC. (5) discharge board use dragoon discharge board. Is its advantage: ? Vulgar  cut reads parrot of bad  of Piao of be used to to read the? that display Yong to rush it is OK to when cutting into parts, be returned will makings pin, prevent a makings to arise in punch process retroflexion and because screwy; ② is high speed, accurate strong cut into parts, dragoon discharge board use CrWMn steel, quench hardness 50 ～ 55HRC, to increase the stability of discharge board, use 4 small guide pillar to direct, small guide pillar and guide-post bushing clearance are 0.

005 ～ 0.

Bedspring of 01mm; ③ discharge is used be able to bear or endure fatigue puissant and rectangular bedspring, ensure the stripping force of discharge board is large and motion is smooth; ④ uses discharge board to set a protection to flotsam punch, meantime is unoccupied place for 0.

005 ～ 0.

01mm, those who be less than punch and sunken model is strong reduce gap, can improve mould life greatly. Discharge board sets apply mechanically bolt to a string of 1 in bolster plate 31 on, prevent to set covered change to move. Discharge board is in those who curve figuration part above mill empty abdicate, ensure a makings is expedite in sending into the process. (6) curves the design of figuration part. Outfit of punch of 3 turns when curving figuration and plastic punch, 5 curved plastics, caudal plastics punch is on punch fixed head, the others curves figuration punch all outfit is on discharge board, with bolt condole is in bolster plate 31 on, curve figuration the unit that play a top is added inside sunken model, prevent reed card to be inside sunken model. (The design: of 7) mould protection system? Scepter of  of ⑸ of play of  of cease Quan  steals safety of? of obstruct of sew Fei O to sell cannot guide normally, pass journey switch, urgent stop machine, as a result of,protect mould; ② thereby multitask class takes modular punch more, appearance each different, accident is differ, to prevent mould damage, going up, between next pattern plate and upper mould fixed head and bolster plate 31 between setting spacing column and spacing are covered. When trying a model, next above, spacing column just are contacted to allow, it is next closes height reachs a mould dead center of the mould right now, the mould can work normally. Do not work in the mould when, in fluctuation spacing one space block is added among column, assure come away of protruding, sunken model, prevent point damage. Graph composition of a picture of the 3 recognizance that it is a model. The mould works on punching machine of 350kN, ATDA, its close height is 150 ～ 200mm, the mould closes height is 185mm.
