Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of processing molds, in particular to a mold. BACKGROUND

[0002] Flanging refers to a process of bending the edge of a metal sheet inward or outward to a certain angle. Generally, the purpose of flanging is to increase the strength of the structure, increase the fitting size, or prepare for subsequent processing. Punching refers to a process of punching holes in a metal sheet by a punch press or a mold. This process uses the punch of the mold to punch holes in the sheet at the designed position. Punching can be used to reduce the weight of metal parts, improve ventilation, increase assembly functions, etc.

[0003] In the prior art, flanging and punching are usually distributed, that is, flanging is performed first and then punching is performed. This has the advantages of improving processing accuracy, prolonging tool life, reducing material waste, and helping to improve operational flexibility and process controllability. Among them, flanging is divided into single flanging and multiple flanging. Single flanging is completed by single stamping on one punch press, which is suitable for cases with few holes and large hole diameters, and is mainly used for processing structures with simple edges. Multiple flanging is used for cases with many holes, small hole diameters, or complex shapes, and is completed by multiple operations. Multiple punching not only improves the accuracy of the holes, but also avoids excessive impact force concentrated on one process, reduces the stress deformation of the material, and is used for processing thicker or more complex parts. In actual application, punching is usually performed first and then flanging is performed. Punching first ensures the correct position and size of all holes. Then flanging is performed to avoid the influence of flanging on hole position and hole diameter. According to the specific processing requirements and material properties, separate processing of these two steps usually results in a better final product.

[0004] However, in order to achieve the separation of flanging and punching, a complex multi-station mold usually needs to be designed, that is, punching and flanging processes are performed in different positions by different molds. This has the problems of low efficiency, possible reduction of workpiece accuracy, increased cost, and increased process complexity. Under the requirements of high efficiency and high precision production, separate processing is not ideal and cannot meet the production requirements. CONTENT OF THE UTILITY MODEL

[0005] The present application aims to solve one of the technical problems in the related art to some extent. To this end, the present application provides a mold, which has the advantage of reducing the number of molds required for production processes.

DETAILED DESCRIPTION

[0022] Embodiments of the present application are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numbers represent the same or similar elements or elements having the same or similar functions throughout. Based on the embodiments in the embodiments, it is intended to explain the present application, and cannot be understood as a limitation of the present application.

[0023] In this specification, "one embodiment" or "an embodiment" or "example" or "exemplary" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the present disclosure. The appearance of the phrase "in one embodiment" in various places in the specification does not necessarily refer to the same embodiment.

[0024] Embodiments:

[0025] In the existing production process, it is not uncommon for the flanging process and the punching process to be carried out separately during metal processing. Usually, these two processes are carried out independently, and the purpose of separate operation is to ensure the accuracy and quality of each step. However, this separate process also has some potential disadvantages and problems. Separating flanging and punching means multiple operations, which can lead to longer processing cycles and lower production efficiency. If repositioning and adjustment are required between each process, the time and cost will be further increased. If punching and flanging need to be carried out on different equipment, it will increase the investment in equipment and the complexity of the production line, further reducing production efficiency. At the same time, if flanging and punching are carried out on different equipment, the workpiece needs to be positioned each time. Due to the accumulation of positioning errors, the position or shape of the hole may not fully meet the requirements, especially in mass production, such errors will affect the consistency and accuracy of the product. And when flanging and punching are carried out separately, the shape after flanging and the hole position may deviate slightly, resulting in inaccurate hole position, especially in parts that require high precision matching, the deviation may affect the subsequent assembly or use performance. In addition, separating flanging and punching may result in some material waste. For example, a certain amount of waste may be generated during punching, and in the subsequent flanging process, some materials may not be fully utilized due to shape changes. Since each process is carried out separately, each process requires specific tools and equipment, which not only increases material waste but also increases equipment maintenance and operation costs.

[0026] To this end, the inventor provides a mold that can improve production efficiency, reduce process complexity, and improve product accuracy.

[0027] As shown in Figure 1 and Figure 2 , the present application provides a mold comprising a top plate 10, a bottom plate 20 and at least one processing module 30. The number of simultaneous processing lines can be adjusted according to the number of processing modules 30, and the structure design of the top plate 10 and the bottom plate 20 has high rigidity to withstand pressure and stress under different processes.

The moving direction of the top plate 10 is the same as the direction of the line connecting the top plate 10 and the bottom plate 20, so as to realize the same minimum distance from the top plate 10 to the bottom plate 20 everywhere, and to ensure the stability during processing.

[0030] The forming unit 100 comprises a concave die 110 and a convex die 120, and the concave die 110 and the convex die 120 are matched. Through the above arrangement, the convex die 120 and the concave die 110 are used to realize the pressing of the workpiece to be processed, and the shapes of the convex die 120 and the concave die 110 are matched, that is, the convex shape of the convex die 120 is the same as the concave shape of the concave die 110, that is, the concave die 110 can be closely attached to the convex die 120, so that the shape of the processed workpiece to be processed can conform to the expected shape.

[0031] The concave die 110 is fixed on the side of the top plate 10 close to the bottom plate 20, the convex die 120 is arranged on the side of the bottom plate 20 close to the top plate 10, and the concave die 110 moves along the first direction X following the top plate 10. The concave die 110 is arranged towards the convex die 120 and is fixed with the top plate 10, so that the concave die 110 can move following the top plate 10, and during the movement of the top plate 10 towards the bottom plate 20, the concave die 110 also moves towards the convex die 120, realizing the pressing of the workpiece to be processed.

[0032] The forming unit 100 further comprises a guide column 130 located between the top plate 10 and the bottom plate 20, and the guide column 130 connects the concave die 110 and the convex die 120, the height direction of the guide column 130 is consistent with the first direction X, and the first direction X is parallel to the moving direction of the top plate 10; when the top plate 10 is located at the first position, the guide column 130 is at least partially structured to extend into the convex die 120, when the top plate 10 is located at the second position, the guide column 130 is at least partially structured to extend into the concave die 110, and the guide column 130 is at least partially structured to extend into the convex die 120. Through the above arrangement, the guide column 130 provides a certain determination function for the movement of the top plate 10, improves the accuracy of processing, avoids the inclination in the processing process, and improves the stability of processing.

Through the above arrangement, when the top plate 10 approaches the bottom plate 20, the cutter head 140 will move along the displacement track 150 due to the second direction Y containing a non-zero component along the first direction X, realizing the approach of the cutter head 140 relative to the bottom plate 20, so that the cutter head 140 can contact the workpiece to be processed and complete the punching process. In this embodiment, the included angle between the cutter head 140 and the bottom plate 20 is 60°, the larger the included angle between the cutter head 140 and the bottom plate 20, the higher the efficiency of the cutter head 140 to complete the punching process, the smaller the resistance, the smaller the included angle between the cutter head 140 and the bottom plate 20, the smaller the power required when the top plate 10 moves to the bottom plate 20, the less energy consumed, reducing production cost.

[0035] The displacement track 150 is fixed on the side of the bottom plate 20 close to the top plate 10, and the cutter head 140 is fixed on the side of the top plate 10 close to the bottom plate 20.
