Technical Field

The invention relates to the technical field of cold stamping dies, in particular to a design method of a stacking nest for a cold stamping die.

Background

The mold industry is the basic industry of national economy, and the mold forming process is generally adopted in the current industrial production so as to improve the production rate and the quality of products. The die can be used for producing parts and components by adopting cheap rolled steel plates or steel belts which are produced in large quantities in metallurgical plants as ingredients, and heating is not needed in the production process, so that the die has a series of advantages of high production efficiency, good quality, light weight, low cost, energy and material conservation and the like. The automobile mould is a tool for producing isomorphic products in a large scale and is a process device for producing various technical products. The cold stamping is a press working method which applies pressure to a plate or a blank on a press by using a stamping die at normal temperature to cause the plate or the blank to generate plastic deformation or separation so as to obtain the shape and the size required by a part. The development of the cold stamping technology and the development of the automobile die technology are mutually promoted and jointly developed, and the research and innovation of the cold stamping die have positive significance for the development of modern industry. The cold stamping die is used for production, so that the precision of the product size can be ensured, the surface of the product is not damaged in the processing, and the product quality is stable. In the production process of the cold stamping die, the plates need to be stacked, and in the process, the plates have adhesion phenomena, so that the subsequent manual or mechanical arm is difficult to take and place the parts, two or even more parts are mistakenly fed, the production efficiency is influenced, and the major accidents of die damage, line stop and the like are caused. Therefore, there is a need in the art for a new solution to solve this problem.

Disclosure of Invention

Aiming at the defects of the prior art, the invention provides a design method of a stacking nest for a cold stamping die, which can effectively solve the problems of low production efficiency and equipment damage and line stop caused by wrong picking number due to plate adhesion in the plate picking process of the conventional automatic equipment.

The technical scheme adopted by the invention for solving the technical problems is that the design method of the stacking nest for the cold stamping die comprises the steps of waste position confirmation, stacking nest size calculation, specific position setting and structural drawing verification, and specifically comprises the following steps:

firstly, verifying the stability of a product by using Autoform software, determining the content of each procedure, and determining the shape and the size of a plate material in each procedure;

secondly, dividing a plate waste area according to the size and the shape of a subsequent plate, and confirming the position and the depth of a stacking nest;

thirdly, adding stacking nests according to different plate types in a blanking process, verifying the stability of the process, and designing a structural drawing according to the types of the stacking nests to be divided into two types;

and fourthly, selecting a corresponding punch and a corresponding concave sleeve form according to the thickness of the plate.

Through the design scheme, the invention can bring the following beneficial effects: the invention provides a design method of a stacking nest for a cold stamping die, wherein in the production process of automobile parts, part of parts need to be stacked and stored after plate blanking and prepare for the work of the subsequent working procedure; after blanking is finished, in the process of stacking the plates, because the plates have stacking pits, each plate is not completely attached in the process of manually or automatically picking the plates by a manipulator, so that the phenomenon that the plates are adhered due to air pressure, antirust oil and the like can be avoided, the time wasted by separating the plates is avoided, and the working efficiency is improved; meanwhile, the parts are independent from each other and are not attached, so that the normal production of a production line can be ensured, the production safety is ensured, and the serious accident that the stacking of a plurality of parts causes the stop or damages to molds, production equipment and the like is avoided; compared with the traditional method of trimming the size of the plate only in the blanking process, the method solves the problems of adhesion accumulation, difficulty in taking and placing, high requirement on piece taking equipment and the like caused by stacking of trimmed plates, increases the shape while trimming the required size of the plate in the blanking process by considering the position of the waste of a subsequent product, saves the process content, provides convenience for the subsequent work content, shortens the time for taking and placing the piece, and avoids a series of problems of machine halt of production, mold damage and the like caused by adhesion of a plurality of pieces.
