Description
[technical field]
The utility model relates to diel, relates in particular to a kind of metal food tank bottom punch die.
[background technology]
As shown in Figures 1 to 4, metal food tinning need to be extracted the residual air in tank out when encapsulation, and adds protective gas, in case food generation oxidation deterioration.Adapt therewith; the bottom 2 of metal food tinning has uniform a plurality of salient points 201 (being generally 7-15) along its periphery; to support and form gas channels by salient point 201 between can body 1 and bottom 2, reach bottom 2 before carrying out seaming pressing with can body 1 by tank in the residual air performance requirement extracting out, protective gas is added.
For meeting the requirement of food security, to comprising that the inner surface on bottom surface all scribbles food essential oil protective layer, in process, can not there is slight scratch (scratching), this has proposed high requirement to the Design and manufacture of mould.For a long time, surperficial scratch has become insoluble problem in this type of stamping production process.
Traditional metal food tank bottom salient point punch die structure is as shown in Fig. 5 to Fig. 8, wherein, Bumping Process punch 3 as shown in Figure 5 and Figure 6, Bumping Process die 4 as shown in Figure 7 and Figure 8, a plurality of point-like convexes 303 of Bumping Process punch 3 are corresponding uniform with a plurality of concave points 403 of Bumping Process die 4, this kind punch die structure processing technology is complicated, requirement on machining accuracy is high, upper and lower mould contraposition requires precisely, the concave point of Bumping Process punch salient point and Bumping Process die can not misplace, otherwise easily cause bottom salient point shape lack of standardization, the defects such as bottom face coat scratch.
[summary of the invention]
It is simple that the technical problems to be solved in the utility model is to provide a kind of processing technology, to machining accuracy and the less demanding metal food tank of upper and lower mould contraposition bottom punch die.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is, a kind of metal food tank bottom punch die, comprise upper bolster, die shoe, Bumping Process punch and Bumping Process die, the end face of Bumping Process punch comprises a plurality of point-like convexes that are arranged on same circumference, the end face of Bumping Process die comprises the groove of annular, when Bumping Process punch and Bumping Process die are involutory, a plurality of point-like convexes of Bumping Process punch enter into the groove of the annular of Bumping Process die.
Above-described metal food tank bottom punch die, comprises upper mold core and knockout rod, and Bumping Process punch is bowl-type, comprises side plate and the base plate of tubular, and described bump arrangement is on the end face of tubular side plate; The base plate of Bumping Process punch comprises plurality of through holes, and upper mold core comprises a plurality of Convenient tables, and the Convenient table of upper mold core is connected with upper bolster through the through hole of Bumping Process punch; Upper bolster central authorities comprise through hole, and knockout rod is connected with the base plate of Bumping Process punch through the through hole of upper bolster central authorities.
Above-described metal food tank bottom punch die, Bumping Process die is fixed on die shoe, and the end face of Bumping Process die and upper mold core respectively comprises the moulding convex of bottom annular muscle, and the moulding convex of Bumping Process die and upper mold core moulding convex are radially staggering.
The utility model is holistic annular groove by original uniform all concave point UNICOM on die, and annular groove only need be controlled radial dimension, and processing technology is simple more than the concave point of separating, and greatly reduces die difficulty of processing; The die of annular groove is less demanding to upper and lower mould contraposition, and the stamping processing can not only meet the performance requirement of product, has effectively solved again a difficult problem for the long-standing face coat scratch of like product.

[specific embodiment]
The structure of the utility model embodiment metal food tank bottom punch die, as shown in Fig. 5, Fig. 6, Fig. 9 to Figure 11, comprises upper bolster 6, die shoe 7, upper mold core 8, knockout rod 9, Bumping Process punch 3 and Bumping Process die 4.
Bumping Process punch 3 is bowl-type, comprises side plate 302 and the base plate 301 of tubular.The end face of Bumping Process punch 3 tubular side plates 302 has a circle to be arranged in 15 point-like convexes 303 on same circumference.
The base plate 301 of Bumping Process punch 3 has three through holes 304, upper mold core 8 includes three Convenient tables 801, the Convenient table 801 of upper mold core 8 is connected with upper bolster 6 through the through hole 304 of Bumping Process punch 3. and there is a through hole 601 in the central authorities of upper bolster 6, and knockout rod 9 is connected through the through hole 601 of upper bolster 6 central authorities and the base plate 301 of Bumping Process punch 3.
