Description

Mould

Technical Field

The invention relates to the technical field of processing dies, in particular to a die.

Background

The flanging means a process of bending the edge portion of the metal plate inwardly or outwardly into a certain angle through a certain process. Typically, the purpose of the flange is to increase the strength of the structure, increase the mating dimensions, or provide for subsequent processing. Punching refers to a process of punching a metal plate by a punch or a die. The process utilizes the punch head action of the die to punch holes in the plate according to the positions required by design. Punching can be used to reduce the weight of the metal piece, improve ventilation, increase assembly functions, etc.

In the prior art, most flanging and punching are performed in a distributed manner, namely, the punching process is performed after flanging is performed, so that the processing precision can be improved, the service life of a tool is prolonged, the material waste is reduced, and the flexibility of operation and the controllability of the process are improved. The flanging is divided into single flanging and fractional flanging, the single flanging is used for punching all holes through single punching on one punching machine, the single flanging is suitable for the conditions of small number of holes and large aperture, the single flanging is used for processing a structure with simpler edges, and the fractional flanging is used for the conditions of more holes, small aperture or complex shape and is completed through fractional operation. The precision of the hole can be improved by punching the holes in multiple times, excessive impact force can be prevented from being concentrated on one working procedure, and the stress deformation of the material is reduced, so that the method is used for processing thicker or more complex parts. In practical applications, a punching process is performed first and then a flanging process is performed. The punching process is performed first to ensure that all holes are correct in position and size. And then flanging operation is carried out to avoid the influence on hole sites and aperture during flanging. Separate processing of these two steps generally results in a better quality final product, depending on the specific processing requirements and material properties.

However, in order to perform flanging and punching in several steps, it is generally necessary to design complex multi-station dies, i.e. the punching process and the flanging process are performed by different dies at different positions. The method has the problems of low efficiency, possibly reduced workpiece precision, increased cost and improved process complexity. Under the requirements of high-efficiency and high-precision production, the separation treatment is not ideal, and the production requirement cannot be met.

Detailed Description

Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The examples in the embodiments are intended to illustrate the present invention and are not to be construed as limiting the present invention.

Reference in the specification to "one embodiment" or "an example" means that a particular feature, structure, or characteristic described in connection with the embodiment itself can be included in at least one embodiment of the disclosure. The appearances of the phrase "in one embodiment" in various places in the specification are not necessarily all referring to the same embodiment.

Examples:

In the existing production flow, the phenomenon that the flanging process and the punching process are carried out separately in the metal processing process is not rare. Typically, the two processes are performed independently of each other, with the purpose of separate operations to ensure the accuracy and quality of each step. However, there are also some potential drawbacks and problems with this separate process flow. Separate flanging and punching means that multiple operations are required, which may result in longer processing cycles and lower production efficiency. The time and cost spent is further increased if repositioning and adjustment is required between each process step. If punching and flanging are to be performed on different equipment, this will increase equipment investment and complexity of the production line, further reducing production efficiency. Meanwhile, if flanging and punching are performed on different devices, the workpiece needs to be positioned during each operation. The position or shape of the holes may not be fully satisfactory due to the accumulation of positioning errors, which may affect the consistency and accuracy of the product, especially in mass production. When the flanging and punching are performed separately, minor deviations may occur in the shape and the hole position after flanging, resulting in inaccurate hole positions, and particularly in parts requiring high-precision matching, the deviations may affect subsequent assembly or usability. Furthermore, the separate execution of the flanging and punching may result in some waste of material. For example, a certain amount of scrap may be generated during punching, and during subsequent flanging, some of the material may be underutilized due to shape changes. Since each process is performed separately, each process requires specific tools and equipment, which not only increases the waste of materials, but also increases the maintenance and operating costs of the equipment.

In this regard, the inventors have provided a mold that can improve production efficiency, reduce process complexity, and improve product accuracy.

As shown in fig. 1 and 2, the present application provides a mold comprising a top plate 10, a bottom plate 20, and at least one processing module 30.

The moving direction of the top plate 10 is the same as the connecting line direction of the top plate 10 and the bottom plate 20, so that the minimum distance between the top plate 10 and the bottom plate 20 is the same, and the stability in the processing process is ensured.
