Abstract
A processing technology and a die for a steel drum plug relate to an improved processing technology and a reduced blanking deep drawing die for the steel drum plug. The processing steps of the steel drum plug comprise: 1) blanking and deep drawing, namely blanking and deep drawing a steel plate into a semi-finished product; 2) and (4) molding, namely directly processing the semi-finished product into a finished product meeting the international size. The process requirement is realized by the outer diameter size of the upper punch notch of the blanking drawing die. The method has the advantages of few working procedures, high efficiency, low cost, raw material saving, manpower and material resources saving and the like.
Description
The present invention relates to the improvement and the designed mould of technological requirement of steel drum plug production and processing technology.
At present, steel drum plug is standardization, and its processing technology adopts the following step: 1) blanking and drawing is box-like semi-finished product with drawing and forming shape behind the steel plate blanking; 2) cooperage spigot of relevant size conforms GB is processed into semi-finished product in moulding; 3) cut edge, meet GB to guarantee steel drum plug exterior rim outside dimension.
To the procedure of processing of above-mentioned steel drum plug, the per pass operation is all finished by mould, and these moulds are respectively: 1) blanking and drawing mould; 2) shaping mould; 3) edger.The installation diagram of blanking and drawing mould wherein, as shown in Figure 1, upper punch 3 is fixed on the die shank 1, there is material returned bar 2 at its center, counterdie 4 is fixed on the counterdie fixed disk 6, and counterdie fixed disk 6 is fixed on the base 7, and low punch inner core 5 is in the middle of counterdie 4, and be fixed on the counterdie fixed disk 6, and the external diameter of upper punch 3 incision, be 83.8 ± 0.05mm to processing big steel drum plug; To processing its external diameter of little steel drum plug is 47 ± 0.05mm.Because the blanking size of blanking and drawing operation is big, in order to guarantee the physical dimension of steel drum plug, so the side cut operation card of going bail for also must be arranged after molding procedure.The many costs of operation are just high, and cut edge and wasted raw material, and therefore the cost of present large and small steel drum plug is higher.
The objective of the invention is to design a kind of new processing technology of steel drum plug, dwindle the blanking die size, remove the side cut operation.
The present invention is achieved in that the processing technology of steel drum plug comprises the following steps: 1) blanking and drawing, the steel plate blanking and drawing is become semi-finished product, its each spot size and state's dimensioning are close; 2) moulding directly is processed into the size that each spot size all meets GB with semi-finished product, is 62.0 ± 0.5mm as physical dimension, 61.5 ± 0.5mm, 28.5 ± 0.5mm.
The blanking and drawing mould that the blanking and drawing operation is used mainly is made up of die shank, upper punch, material returned bar, counterdie, low punch inner core, counterdie fixed disk and base, and wherein the external diameter of the upper punch incision of Jia Gong big steel drum plug is 78.5 ± 1mm; The external diameter of processing the upper punch incision of little steel drum plug is 40 ± 1mm.
The present invention compared with prior art has following advantage: 1) the steel drum plug manufacturing procedure is few, efficient is high, cost is low, 2) because no side cut operation, saved raw material; 3) owing to lacked the side cut operation, use a punch press and mould less, reduced the waste of manpower and materials.
Be elaborated below in conjunction with accompanying drawing:
Fig. 1 is former blanking and drawing mould installation diagram;
Fig. 2 is a blanking and drawing mould upper punch part drawing;
Fig. 3 is the later half finished figure of blanking and drawing of the present invention;
Steel drum plug comprises big steel drum plug and little steel drum plug, their processing technology is identical, it is the drift inner core size difference of the external diameter of upper punch incision, concrete procedure of processing is as follows: 1) blanking and drawing, behind blanking and drawing on the blanking and drawing mould, be processed into semi-finished product with steel plate, as shown in Figure 3,2) moulding, the part to first procedure on shaping mould carries out shaping, makes each spot size of cooperage spigot directly reach GB.
The used blanking and drawing mould of blanking and drawing operation mainly is made up of die shank 1, upper punch 3, material returned bar 2, counterdie 4, low punch inner core 5, counterdie fixed disk 6 and base 7, the external diameter of wherein big steel drum plug upper punch 3 incision is: 78.5 ± 1mm, the external diameter of the incision of little steel drum plug upper punch 3 is: 40 ± 1mm, as shown in Figure 2.The external diameter of the internal diameter of counterdie 4 and upper punch 3 incision is complementary, and belongs to tight fit.
Claims (2)
1, a kind of production technology of steel drum plug is characterized in that: it is made up of following two steps: 1) blanking and drawing, be processed into semi-finished product with steel plate on the blanking and drawing mould; 2) steel drum plug that meets state's dimensioning directly is processed into semi-finished product in moulding.
2, the blanking and drawing mould mainly is made up of die shank (1), upper punch (3), material returned bar (2), counterdie (4), low punch inner core (5), counterdie fixed disk (6) and base (7), it is characterized in that: the outside dimension of large and small upper punch (3) incision is respectively: 78.5 ± 1mm, 40 ± 1mm, counterdie (4) is complementary with upper punch (3) incision external diameter, belongs to tight fit.
