Example Embodiment

[0009] Specific implementation mode 1: Combination Figure 1~Figure 14 To illustrate this embodiment, this embodiment includes an upper mold assembly 1, a lower mold assembly 2 and at least two guide posts 3. The upper mold assembly includes an upper mold base 1-1, a punch backing plate 1-7, and a punch Fixed plate 1-8, discharge ring 1-10, at least two guide sleeves 1-2, two punch positioning pins 1-6, at least four insert punches 1-9, eight discharge rubber 1- 11 Several unloading screws 1-3, several punch fixing screws 1-4 and several fixing screws 1-5, at least two guide sleeve holes are symmetrically provided on the end surface of the upper mold base 1-1 1. Each guide sleeve hole 1-1-1 is equipped with a guide sleeve 1-2. The guide sleeve 1-2 and the upper mold base 1-1 are assembled by interference fit, and at least four insert punches 1-9 The ring-shaped component is arranged on the outer surface of the flange 1-8-1 of the lower end surface of the male mold fixing plate...

Example Embodiment

[0010] Specific implementation manner two: combination Figure 7 , Figure 8 , Figure 13 with Figure 14 To explain this embodiment, the end surface of each insert convex mold 1-9 and the insert concave mold 2-4 in this embodiment is provided with an upper mold plane or upper mold convex surface along the arc length direction, and each insert concave mold 2-4 The end surface corresponding to the insert punch 1-9 is provided with a lower die convex surface or a lower die plane corresponding to the upper die plane or the upper die convex surface along the arc length direction, that is, each insert punch 1-9 and When the corresponding end surface of the insert die 2-4 is the upper die plane along the arc length direction, the end surface of each insert die 2-4 and the insert punch 1-9 corresponding to the end surface along the arc length direction is the convex surface of the lower die , When the end surface of each insert convex mold 1-9 corresponding to the insert concave mold 2...

Example Embodiment

[0011] Specific implementation mode three: combination Image 6 with Picture 12 To describe this embodiment, the numbers of the insert convex molds 1-9 and the insert concave molds 2-4 of this embodiment are both six. This design makes the lower end surface of the ring assembly composed of six insert punches 1-9 and the upper end surface of the ring assembly composed of six insert dies 2-4 have many waves along the circumference, and the cutting area is small and the punching Cutting power is small. The other components and connection relationships are the same as in the first embodiment.

Abstract

The invention discloses a large-scale embedded blanking mould, and relates to a blanking mould, aiming to solve the problems of materials waste, difficult manufacture, short service life of a mould, difficulty in sharpening, maintenance, assembly and disassembly during integrally manufacturing a large-scale blanking mould and a punch die. The mould comprises an upper die component, a lower die component and at least two guide columns, wherein the upper die component comprises an upper die seat, a terrace die pad, a terrace die fixing board, an unloading ring, at least two guide sleeves, two terrace die positioning pins, at least four embedded terrace dies, eight unloading rubbers, a plurality of unloading screws, a plurality of terrace die fixing screws, and a plurality of fixing screws, the lower die component comprises a lower die seat, an embedded female die fixing seat, a plurality of fixing seat fixing screws, at least four embedded female dies, a plurality of female die fixing screws, two female die positioning pins and at least two material guiding and blocking pins, one end of each guide column is arranged in the guide sleeve corresponding to the upper die component, and the other end of each guide column is arranged in the guide column hole corresponding to the lower die component. The mould is applied in the blanking of a large batch of thick board materials.

Description

technical field [0001] This patent relates to a punching die, in particular to an insert block combined punching die. Background technique [0002] In the metal and non-metal machinery manufacturing industry, most of the products are mass-produced. If the production is produced by sheet blanking, the blanking die is inseparable. The design structure of the die is very important. If the structure is unreasonable, the life of the die will be greatly reduced. decrease, leading to an increase in product cost. The liquefied petroleum gas steel cylinders produced by our factory are made of plates with upper and lower bodies after blanking and then deep drawing. The thickness of the steel plate is 3mm, and the diameter of the blanking part is φ640mm, which is a large blanking part in the stamping process technology. The punch and die of the original blanking die are an integral structure, the waste of mold material is large during mold making, the mold making is very complicated,...
