specific Embodiment approach 1

[0009] Specific implementation mode one: combine Figure 1 to Figure 14 Describe this embodiment, this embodiment comprises upper die assembly 1, lower die assembly 2 and at least two guide posts 3, upper die assembly includes upper die base 1-1, punch backing plate 1-7, punch Fixed plate 1-8, unloading ring 1-10, at least two guide sleeves 1-2, two punch positioning pins 1-6, at least four insert punches 1-9, eight unloading rubbers 1- 11 Several discharge screws 1-3, several punch fixing screws 1-4 and several fixing screws 1-5, and at least two guide sleeve holes 1-1- 1. A guide sleeve 1-2 is installed in each guide sleeve hole 1-1-1, and 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 formed ring assembly is arranged on the outer surface of the flange 1-8-1 of the lower end face of the punch fixing plate 1-8, and each insert punch 1-9 is fixed on the punch by the insert punch fixing screw 1-4. O...

specific Embodiment approach 2

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

specific Embodiment approach 3

[0011] Specific implementation mode three: combination Figure 6 and Figure 12 The present embodiment will be described. The number of insert punches 1-9 and insert dies 2-4 in this embodiment is six. This design makes the lower end face of the ring assembly formed by six insert punches 1-9 and the upper end face of the ring assembly formed by six insert dies 2-4 have many waves along the circumference, and the punching shear area is small and punching The cutting force is small. Other components and connections are the same as those 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,...
