Detailed Description
In order to make the technical means, the original characteristics, the achieved purposes and the effects of the invention easily understood, the invention is further described below with reference to the specific embodiments and the attached drawings, but the following embodiments are only the preferred embodiments of the invention, and not all embodiments. Based on the embodiments in the implementation, other embodiments obtained by those skilled in the art without any creative efforts belong to the protection scope of the present invention.
Specific embodiments of the present invention are described below with reference to the accompanying drawings.
As shown in figures 1-2, the Kovar ring of 3225 specification and the Kovar ring of 2016 specification, because of their dimensional characteristics, design a precision die to punch at one time and form two products of different specifications, meet the technical requirement of two products of specifications and be the unique point of die design, have improved material yield and production efficiency.
The die is a continuously-acting progressive die and comprises an upper die base, a fixed base plate, a fixed plate, a discharging base plate, a concave die cushion block, a lower die base, an inner ball guide column, a positioning needle, a material guide plate and the like.
The single upper die base insert consists of a punching male die 1, a 2016 inner frame male die 2, a 2016 outer frame male die 3, a 2016 blanking male die 4, a 3225 inner frame male die 5, a 3225 outer frame male die 6 and a 3225 blanking male die 7; the single lower die holder insert consists of a locating hole female die 8, a 2016 inner frame female die 9, a 2016 outer frame female die 10, a 2016 blanking female die 11, a 3225 inner frame female die 12, a 3225 outer frame female die 13 and a 3225 blanking female die 14.
The mold design meets the product specifications of 2016 and 3225 specification Kovar rings (all units in mm herein).
The 2016 Covar ring sizes are inner frame 1.59(+0.01/-0.02) × 1.19(+0.01/-0.02), outer frame 1.90 (+ -0.02) × 1.50 (+ -0.02);
the specification 3225 includes kovar ring sizes of 2.40(+0.01/-0.02) × 1.70(+0.01/-0.02), and outer frame sizes of 2.80 (+ -0.02) × 2.10 (+ -0.02).
By utilizing the principle that the size of the inner frame of the Kovar ring is 2.40X 1.70 in the specification of 3225 and is larger than the size of the outer frame of the 2016 Kovar ring is 1.90X 1.50 in the specification, the 2016 Kovar ring in the specification is designed in the inner side, and the model is called as a stamping die for short.
When the die works, the feeder feeds the metal material belt into the punching positioning hole at the head end of the die for positioning and guiding.
The first part of the die completes the punching of the 2016 type kovar ring, and considering the precision of the product, the 2016 type inner frame is punched three times respectively, the pre-punched inner frame → the fine-punched inner frame, and the size change of the product inner frame is 1.20 +/-0.02 +/-0.08 +/-0.02 → 1.40 +/-0.02 +/-1.00 +/-0.02 → 1.59(+0.01/-0.02) < 1.19(+ 0.01/-0.02); 2016 specification frame carries out fine blanking frame 1.90(± 0.02) × 1.50(± 0.02) and product blanking respectively, and the mould design is continuous progressive die, above-mentioned five step blanking is accomplished cross section evenly distributed 4 specification 2016 kovar ring products, and the principle of above-mentioned mould design blanking is repeated in sixth step to tenth step, different designs with the aforesaid, the mould is accomplished the cross section evenly distributed 5 specification 2016 kovar ring products, these 5 product even intervals are in the space of reserving of 4 products of former cross section evenly distributed, from this mould completion ten steps after, can produce 9 products continuously, the die yield of unit interval is high.
After a specification 2016 Kovar ring product is blanked out by a die male die part on a metal material strip, the die is designed to select a blank position of a part of the metal material strip after being blanked, a corresponding upper sharp and lower specification positioning guide needle is designed to perform accurate positioning guide, and the metal material strip synchronously moves horizontally along with the up-and-down movement of the die.
The second part of the die completes the blanking of the 3225-sized kovar ring, and in the operation of the original metal strip, because an inner frame of 1.90 × 1.50 is generated, the 3225-sized inner frame die is designed to perform the blanking twice in consideration of the precision requirement of a product, namely a pre-punched inner frame → a fine-punched inner frame, and the size change of the inner frame of the product is 2.31 (+ -0.02) × 1.61 (+ -0.02) → 2.40(+0.01/-0.02) (+ 1.70(+ 0.01/-0.02); then fine blanking outer frame 2.80 (+ -0.02) × 2.10 (+ -0.02) and product blanking of 3225 specification products are carried out. The die is designed as a continuous progressive die, the four-step blanking is to complete the blanking of 3225-specification products only by reducing the first step action of 2016 pre-punching an inner frame in the case that 4 2016 kovar rings with specifications are uniformly distributed on the original cross section at the corresponding positions to be blanked, and the sixth step to the tenth step repeat the principle of die design blanking, and the 5 3225-specification kovar ring products are still produced on the corresponding positions to be blanked of the 5 2016 kovar ring products with specifications and uniformly distributed on the cross section.
The first part and the second part jointly complete the production of 9 fellable ring products with the same transverse section, the formed products are respectively guided out and collected by 9 guide pipes below the die, and the belt materials left on the die are all metal waste materials.
The progressive die design completes the generation of 9 products with the specification of 2016 kovar rings from the first step to the tenth step, completes the generation of 9 products with the specification of 3225 kovar rings from the eleventh step to the nineteenth step, and the whole set of die completes the continuous working principle of the punching design of the specification of 3225 kovar rings and 2016 kovar rings.
The innovative characteristics of the mould are as follows:
1. the same raw material, because of the different characteristics of the specification, the size and the size of the product, the small-size product is designed in the inner frame of the large-size product, the use of the raw material is fully utilized, precious metal is saved, and the utilization rate of the precious metal material is improved. The mold design fully meets the requirement of precision machining of products. Meanwhile, the mold is designed to be a continuous progressive mold, so that the product yield is improved.
2. Because the concentricity and the punching precision of the Kovar ring product are required to be +/-5 microns, the inner frame is punched for three times in the 2016 type punching product, the manufacturing requirement of high precision is completed by two times of pre-punching and one time of fine punching, and meanwhile, when the progressive die moves forward, the upper-sharp lower-gauge positioning guide-in needle is used for performing precise positioning, so that the 3225 type punching product in the lower wheel is guaranteed, and the size precision of the 3225 type punching product is guaranteed.
3. The production efficiency of the Kovar ring products with two specifications is maximized, 9 products are designed at the transverse section at the same time, the products are punched at the same time, the section 4 and the section 5 are completed in different steps, the 9 products are completed together, and the continuous production of the 9 products is completed by the mould in 19-level steps at one time.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and the preferred embodiments of the present invention are described in the above embodiments and the description, and are not intended to limit the present invention.
