Description
Technical Field
The invention belongs to the technical field of stamping processing, and particularly relates to a progressive die fine stamping method.
Background
The stamping die is commonly used in panel beating processing, to punching a hole of panel beating, utilizes the drift of mould to carry out the punching press, and is quick and regular. However, the die-cut area of the waste material of smart punching to the panel beating is less, and because the panel beating middle part does not have the mould to support moreover, leads to smart drift punching sheet metal in-process, and the easy suction template face of smart punching head leads to the fact to jump the waste material, leads to the product to crush and scrap, increases the rejection rate.
Disclosure of Invention
The invention aims to provide a progressive die fine blanking method, which aims to solve the technical problem that the progressive die is easy to suck out of a die plate surface in the fine blanking process to cause scrap jumping.
In order to solve the technical problem, the invention provides a continuous die fine blanking method, which comprises the following steps:
s1, performing rough punching on the target metal plate to form a rough punching female hole on the target metal plate, wherein residual waste materials are left at the hole edge of the rough punching female hole, at least one material connecting bridge is formed in the rough punching female hole, the material connecting bridge is connected with the residual waste materials in the rough punching female hole, and each connecting bridge divides the rough punching female hole into a plurality of rough punching sub-holes;
and S2, carrying out fine punching on the coarse punching female hole by using a single fine punching head, and flushing away the residual waste in each material connecting bridge and the coarse punching female hole by using the fine punching head so as to obtain a target fine punching hole on the target metal plate.
Furthermore, the rough punching female hole is formed by punching two rough punching heads, and a material connecting bridge is formed in the rough punching female hole.
The continuous die fine blanking method has the beneficial effects that the material connecting bridge is added to support the waste materials, and the waste materials are clamped in the knife edge when being punched by the fine blanking head. The template surface is prevented from being worn out by the fine punching head, and the product is prevented from being damaged and scrapped due to the sucked template surface. The scrap jumping is prevented, the cost is saved, the rejection rate is reduced, and the yield is improved. The shutdown processing abnormal time is reduced, and the production efficiency is improved.
Additional features and advantages of the invention will be set forth in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. The objectives and other advantages of the invention will be realized and attained by the structure particularly pointed out in the written description and claims hereof.
Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below, and it is apparent that the described embodiments are a part of the embodiments of the present invention, but not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The continuous die fine blanking method of the embodiment comprises the following steps:
and S1, performing rough punching on the target metal plate by using a rough punching head so as to form a rough punching female hole on the target metal plate after the rough punching. Part of residual waste materials are left on the hole edge of the rough punching female hole, and at least one connecting bridge is formed in the rough punching female hole. The connecting bridges connect the residual waste materials in the rough punching female hole, and each connecting bridge divides the rough punching female hole into a plurality of rough punching sub-holes.
And S2, carrying out fine punching on the coarse punching female hole by using a single fine punching head, and flushing away the residual waste in each material connecting bridge and the coarse punching female hole by using the fine punching head so as to obtain a target fine punching hole on the target metal plate.
The material connecting bridge is added to support the waste materials, and the waste materials are clamped in the knife edge when being punched down by the fine punch. The template surface is prevented from being worn out by the fine punching head, and the product is prevented from being damaged and scrapped due to the sucked template surface. The scrap jumping is prevented, the cost is saved, the rejection rate is reduced, and the yield is improved. The shutdown processing abnormal time is reduced, and the production efficiency is improved.
Specifically, the rough punching female hole in the present embodiment is formed by punching two rough punches, and a connecting bridge is formed in the rough punching female hole. The rough punching female hole is divided into two rough punching sub-holes through the material connecting bridge, so that the subsequent fine punching head can conveniently perform fine punching. The waste materials are easy to be clamped in the knife edge of the fine punch, the sucked template surface is prevented from pressing and damaging products, and the reject ratio is reduced.
In summary, the continuous die fine blanking method of the invention is used to add the material connecting bridge for supporting the waste material, and the waste material is clamped in the knife edge when being punched by the fine blanking head. The template surface is prevented from being worn out by the fine punching head, and the product is prevented from being damaged and scrapped due to the sucked template surface. The scrap jumping is prevented, the cost is saved, the rejection rate is reduced, and the yield is improved. The shutdown processing abnormal time is reduced, and the production efficiency is improved.
