Description

A reinforced stamping die cantilever

technical field

The utility model relates to a press accessory, in particular to a stamping die cantilever.

Background technique

When the stamping die is working, the transmission part drives the working head to move up and down to realize stamping. Since the stamping die is under a lot of pressure when it is working, when the stamping die is used for production, the cantilever of the stamping die with a cantilever is stressed and prone to breakage, especially when the cantilever of the equipment is long. When the force is greater, the fracture is more serious. Otherwise, the service life of the cantilever of the general stamping die is short.

In view of the above, there are some existing improved technical solutions, such as increasing the size of the cantilever and changing the casting material, but the effect is still not obvious, which still limits the life and production efficiency of the mold to a large extent, and increases the cost.

Utility model content

In view of the above-mentioned shortcomings of the stamping die cantilever being easy to break and short service life, the utility model provides a reinforced stamping die cantilever.

The utility model relates to a reinforced stamping die cantilever, and a reinforcing rib network is arranged inside the cantilever. The stamping die ensures the strength and toughness of the cantilever when the cantilever part appears, and solves the problem that the cantilever part breaks when it is repeatedly stressed. This kind of mechanism can be used for stamping dies that require cantilever pressing.

Preferably, the reinforcing rib network includes main ribs and auxiliary ribs, the auxiliary ribs include connecting ribs, the main ribs are distributed along the axial direction of the cantilever, nodes are arranged on the main ribs, each node is provided with connecting ribs, and adjacent main ribs are connected together through the connecting ribs.

Preferably, the connecting ribs on the same node are separated by a distance of 2 to 3 diameters of the main ribs. Make the connecting ribs evenly stressed, and keep the rib network at an appropriate distance from the casting wall.

Preferably, the auxiliary ribs further include transverse ribs, and the transverse ribs extend along the main force-bearing widened part of the cantilever. The design of the transverse ribs here is to increase according to the shape and stress of the cantilever to ensure the strength of the cantilever and avoid splitting due to partial force concentration.

Preferably, the transverse ribs, connecting ribs and main ribs are welded and connected by welding rib heads. Here, the transverse ribs, connecting ribs and main ribs are connected together by welding.

Preferably, alloy steel bars are selected for the reinforcing rib network. The rib network after casting still has high strength and toughness, and the chemical composition of the welded joint is similar to that of the main rib and connecting rib.

Preferably, both sides of the cantilever are connected to the limit block through pressing parts, a stamping part is provided on the same side as the limit block, and a pressure source is provided under the cantilever corresponding to the stamping part.

When designing the cantilever parts, set the reinforcement network (including main reinforcement and connecting steel bars) on the stress-bearing parts of the cantilever. Before casting the cantilever parts, fix the reinforcement network in the cantilever. After pouring and cooling, the casting and the reinforcement network are combined together. The reinforcing rib network improves the strength and toughness of the casting, and can also act as a chilling effect, which is beneficial to reduce casting defects such as shrinkage cavities and porosity in the casting, refine the grains, and improve the mechanical properties of the casting matrix. The mechanical combination of the rib network and the casting improves the strength and toughness of the cantilever pressing material and the plastic stress-bearing parts, thereby improving the service life of the cantilever and other stress-bearing parts. The structure is simple, the practicability is strong, and the service life of the cantilever is guaranteed.

A method for manufacturing the above-mentioned reinforced stamping die cantilever. The main reinforcement and auxiliary reinforcement are welded together to form a reinforcement network; then the reinforcement network is fixed in the cantilever, and then pouring is performed.

As mentioned above, according to the stamping die reinforced cantilever of the present invention, it has the following beneficial effects: the structure not only improves the strength and toughness of the casting macroscopically, but also can refine the crystal grains, reduce casting defects such as shrinkage cavities and porosity in the casting, Improve the mechanical properties of the casting matrix. In this way, it is ensured that the cantilever does not break when the pressing part or the shaping part is repeatedly stressed, the service life is improved, and the life of the mold and production efficiency are improved. In addition to ensuring the service life of the cantilever, pressing parts and shaping parts, the technology of the utility model also has the advantages of simple structure, strong practicability, safety and reliability.

According to Figure 1, a stamping die reinforced cantilever includes a cantilever 1, the two ends of the cantilever 1 are respectively connected to the limit block 3 through the pressing part 2, and a stamping part 4 is provided on the same side as the limit block 3, and the stamping part 4 The pressure source 5 is connected to the bottom of the corresponding cantilever 2 through the pressure source pad 6 . A guide plate 7 is provided on the side of the connection position between the cantilever 1 and the pressing member 2 . The pressure joint 5 exerts pressure on the cantilever 1, the pressing part 2, and the stamping part 4 through the pressure source pad 6, and restricts the movement of the cantilever 1 through the limit block 3, so that the cantilever 1, the pressing part 2 or the stamping part 4 are deformed, When the pressure source 5 acts repeatedly, the pressing part 2 or the cantilever 1 is likely to break, which limits the service life of the cantilever part, affects the production efficiency of the mold, and cannot meet the requirements of large-scale batch production.
