(54) СПОСОБ ИЗГОТОВЛЕНИЯ СБОРНЫХ МАТРИЦ РАЗДЕЛИТЕЛЬНЫХ ШТАМПОВ(54) METHOD OF MANUFACTURING DIVIDING STANDS MATRIX MATRIX

Изобретение относитр к обработке давлением и может быть использовано при изготовлении штампов, например , в электротехнической, приборостроительной промышленности.The invention relates to pressure treatment and can be used in the manufacture of dies, for example, in the electrical, instrument-making industry.

Наиболее близким по технической сущности и достигаемому эффекту вл етс способ изготовлени сборных матриц разделительных штампов из листового материала путем вырубки пластин пуансоном, сборки пластин в пакет и их соединени 1.The closest in technical essence and the achieved effect is a method of manufacturing precast matrices of separating dies from sheet material by cutting the plates with a punch, assembling the plates into a package and connecting them 1.

Недостаток известного способа заключаетс в большой трудоемкости изготовлени составных матриц..The disadvantage of this method lies in the large laboriousness of manufacturing composite matrices.

ЙСвль изобретени - снижение трудоемкости изготовлени сборных матриц разделительных штампов.The invention is a reduction in the laboriousness of manufacturing prefabricated arrays of parting dies.

Поставленна цель достигаетс тем, что согласно способу изготовлени сборных матриц разделительных штампов из листового материала путем вырубки пластин пуансоном, сборки пластин в пакет и их соединени ,перед, вырубкой пластин расплющивают рабочий конец пуансона, нанос т на его боковую поверхность технологическое покрытие толщиной, равной одностороннему расчетному зазору между пуансоном и матрицей при эксплуатации разделительных штампов, придают распл щенному концу, форму и размеры, соответствующие поперечному сечению части пуансона, имеющей технологическое покрытие, после чего отдел ют часть пуансона со стороны расплющенного конца и производ т им вырубку пластин в штампе с упругой матрицей.The goal is achieved by the method of manufacturing precast matrices of separating dies from sheet material by cutting the plates with a punch, assembling the plates into a package and joining them, before the cutting of the plates flatten the working end of the punch, apply a technological coating equal to one-sided on its side surface the calculated gap between the punch and the die during the operation of the dividing dies, gives the split end the shape and dimensions corresponding to the cross section of a part of sone having technological coating, whereupon a portion of the punch is separated from the flattened end and making it m in the die cutting plates with the elastic matrix.

,На фиг. 1 показан пуансон с расплющенными концом и технологическим покрытием на боковой поверхностиf на фиг. 2 - пуансон после обработки расплюще.нного конца} на фиг. 3 представлена схема штамповки пластин сборных матриц в штампе с упругой матрицей., FIG. 1 shows a punch with a flattened end and a process coating on the side surface f in FIG. 2 - punch after processing flattened end of the} end in FIG. 3 shows the scheme of stamping plates of precast matrices in a stamp with an elastic matrix.

Способ изготовд.ени сборных матриц разделительных штампов реализуетс следующим образом.The method for manufacturing precast dividing die matrices is implemented as follows.

Claims

Initially, in some manner, for example by milling, a punch 1 is made with the shape and dimensions of the cross section corresponding to the punch of the parting punch. For 25 the end of the 2 punch 1 flatten. A technological coating 3 is applied to the side surface of the punch 1 with a thickness equal to the one-sided design gap (Zp) between the punch and the die, at which the separating die will be further operated (Fig. 1J. Next, the flattened end 2 of the punch 1, for example by grinding, is shaped and dimensioned according to the cross section of the non-deformed portion of the punch 1, having a coating (Fig. 2). The treated flattened end 2 is separated from the bottom punch 1, thereby obtaining two new punch 4 and 5. The first of the punch 4, which is actually the punch of the separation punch, after removing the technological coating 3, is then used further for its intended purpose. For example, a polyurethane j matrix b is used to cut down the composite matrix plates 7 (Fig. 3). mm then extra ADDITIONAL processing matrix with deprotection chip can be eliminated and replaced Nena lapping surface. At the same time, the actual one-sided gap between the duct punch and the matrix of the separating stamp will be Z Z p + y. The stamp remover can also be made using the ELM method. The economic effect of the implementation of the proposed method is associated with a 3-4 times reduction in the labor intensity of the manufacture of dies by reducing the manual work of adjusting the working profiles of the dies and pullers and replacing the machining by stamping. The invention of the method of manufacturing precast matrices of dividing dies from sheet material by cutting plates with a punch, assembling the plates into a bag and joining them, characterized in the coating thickness equal to the one-sided calculated gap between the punch and the die during the operation of the dividing dies, then the flattened end is given the shape and dimensions, vetstvukschie cross section of part of the punch, -imek Tsey technological coating, whereupon a portion of the punch from the flattened end was separated and t he cutting inserts in the die with an elastic matrix.
