Description

TECHNICAL FIELD

[0001] The utility model relates to sheet metal processing technical field, specifically, relate to a power supply sheet metal shell manufacturing multi -process integration device. BACKGROUND

[0002] In the prior art, the computer power supply hardware shell mold needs to be cut, punched, bent, formed, threaded and riveted. There are mainly two forming methods at present:

[0003] 1) Hardware single punch die: cutting, punching, bending, riveting, threading and other steps are formed by single stamping die in turn. The mold is dispersed into stamping die, cutting die, bending die, riveting die and threading die. After completing one step, the next mold is taken manually for processing. Each processing step is independent and dispersed, the processing speed is slow, the yield is low, the technical requirement is low, and the labor cost is high.

[0004] 2) Hardware continuous die: can solve the cutting, punching and bending forming of three processes. Rivet riveting and hole threading are processed by separate rivet machine and separate threading machine. The hardware continuous die can only complete the product shell modeling of cutting, punching and bending forming. The rivet riveting and hole threading parts need to be processed again by separate rivet stamping die and separate threading die. At the same time, because riveting and threading are processed on the semi-finished product after bending, the threading holes and riveting holes on different bending surfaces must be processed on different surfaces, which leads to the need for additional adjustment of different plane angles, directions and positions, and multiple processing of holes and rivets on different bending surfaces. The production capacity is low, the quality control is difficult, the product processing links are dispersed, which is not conducive to mass production and quality control, the overall hole positioning precision tolerance is usually more than ±0.1mm, and it is not suitable for high-precision product quality control requirements. INVENTION CONTENTS

[0005] The utility model relates to a power supply sheet metal shell manufacturing multi -process integration device, which can solve the above problems.

[0006] In order to solve the above problems, the technical scheme adopted by the utility model is as follows:

[0007] The utility model provides a power supply sheet metal shell manufacturing multi -process integration device, including sheet metal continuous die, automatic rivet machine and automatic threading machine, the sheet metal continuous die sets up punch cutting area and the bending area after punch cutting area, automatic rivet machine and automatic threading machine are installed between punch cutting area and bending area in the punch cutting area and the bending area of sheet metal continuous die, and the riveting and threading of different plane holes are completed before the final bending bending area.

[0008] As a further description of the above technical solutions: the upper die and the lower die of the sheet metal continuous die are both provided with a rivet machine mounting limiting groove for clamping the automatic rivet machine.

[0009] As a further description of the above technical solutions: from front to back, the punching and cutting areas are sequentially provided with three, the automatic rivet machine is located between the front two punching and cutting areas, and the automatic tapping machine is located between the rear two punching and cutting areas.

[0010] Compared with the prior art, the utility model has the advantages that:

[0011] 1) The power supply sheet metal shell manufacturing multi-process integrated device can rearrange the sheet metal continuous die production process, reasonably arrange the entire power supply sheet metal shell machining process, and re-integrate riveting, tapping, and bending. An automatic rivet machine and an automatic tapping machine are designed in the sheet metal continuous die and integrated before the bending area to complete the riveting and tapping processes, realizing the completion of the cutting, punching, bending, riveting, tapping, and other processes of the power supply shell in one complete machining cycle. The integrated continuous die with the rivet machine and the tapping machine has compact overall die size, high machining step efficiency, and avoids the complicated steps of multiple transfers and separate machining of semi-finished products in traditional processes, significantly improving production efficiency.

[0012] 2) In traditional processes, the riveting and tapping processes are not completed in the continuous die. Usually, separate tapping and riveting dies are used to process the semi-finished product after bending. Due to the sheet metal deformation characteristics, bending inevitably causes sheet metal material deformation, resulting in hole positioning tolerance, making it difficult to control the machining accuracy of holes on different bending surfaces, and unable to meet the machining requirements of high-precision products. The power supply sheet metal shell manufacturing multi-process integrated device can realize riveting and tapping before bending, when the product sheet metal material is in a flat state. The riveting and tapping holes on different bending surfaces can be formed at one time before bending. The relative position of the holes has no bending tolerance, avoiding the hole positioning tolerance problem caused by the sheet metal material deformation characteristics in the bending process, meeting the product control requirements of high-precision products. The rivet and tapping hole positioning accuracy can theoretically reach the limit of die machining, i.e., close to zero tolerance.

[0013] 3) solved the personnel safety and material bumping problem in sheet metal machining production, reduced the risk of personal injury of workers. In the traditional process, because each processing step is scattered, a large amount of manual material transportation docking of different processing dies of different steps of semi-finished products is needed. In this process, because the sheet metal material is large in size and heavy in weight, the edge notch is sharp, and the material bumping and personnel injury are extremely easy to occur in the transportation docking process. Based on the power supply sheet metal shell manufacturing multi-process integrated device, the manual docking process in the semi-finished product docking process can be omitted, and the automation degree and production safety factor of the whole machining industry are significantly improved.
