Definitions

  • the present invention relates to a device for feeding sheet metal to a further processing unit.
  • the present invention further relates to a system for processing sheet metal and a method for feeding sheet metal to a further processing unit.
  • the lamination packs contained in a rotor or stator of an electric motor comprise a large number of thin sheets (also known as electrical sheets). These electrical sheets have excellent properties when it comes to conducting and amplifying magnetic fields, with the composition and stress-free nature of the sheets as well as their insulation from one another influencing the efficiency of the electric motor.
  • the present invention aims to provide an approach for feeding sheet metal to a further processing unit in which unproductive downtimes are avoided and material waste is reduced.
  • faster processing should be made possible compared to previous approaches. This in turn should enable efficient production of sheet metal components.
  • a further aspect of the invention relates to a method designed according to the device for feeding sheet metal to a further processing unit.
  • a device for feeding sheets is arranged between the sheet metal rolls and the further processing unit (for example a continuous transfer press and/or a punching tool).
  • This device receives sheet metal from a first sheet metal roll and from a second sheet metal roll.
  • a starting section of the second sheet is fixed (fixed) in a first fixing unit.
  • the end section of the first sheet and the starting section of the second sheet are then processed between the two fixing units and subsequently joined together. After joining, the sheet metal can be passed on to the further processing unit.
  • the device or system according to the invention enables sheet metal to be continuously fed to the further processing unit.
  • sheet metal By connecting the first sheet metal to the second sheet metal when the first sheet metal runs out, sheet metal can be continuously fed to the further processing unit. It is therefore not necessary for the entire remainder of the sheet metal to be removed from the machine when the sheet metal runs out and for production to be interrupted during this time. Unproductive downtime is reduced. In addition, the amount of waste is reduced or minimized. In particular, it makes it possible to avoid the need to stop production at all. In contrast to previous approaches, the efficiency in the processing of sheet metal or in the series production of sheet metal components is increased.
  • connection of the beginning of the new sheet with the end of the old sheet is made in such a way that the forming-punching process is not impaired.
  • the Extension or joining does not overlap, so that the thickness of the sheet in the area of the connection is not increased or only increased insignificantly.
  • a sheet metal storage device in the system according to the invention enables a continuous supply of sheet metal to the further processing unit.
  • buffering can take place during the fixing of the initial section of the second sheet metal and the end section of the first sheet metal in the fixing units and the associated stopping of the forwarding, so that sheet metal can be continuously supplied to the further processing unit.
  • the processing unit is designed to process the abutting edges of the sheets and then to move the abutting edges together in order to create a technical zero gap.
  • the joining unit is designed to connect the sheets at their abutting edges by friction stir welding. In other words, the abutting edges are moved so close to one another that friction stir welding is possible. The connection created thereby meets the required strength without an overlap being necessary. This results in an efficiently implementable connection or an efficiently implementable joining of the sheets.
  • the processing unit is designed to process a first side of the initial section and an opposite second side of the end section and to then move the processed initial section and the processed end section over one another.
  • the joining unit is designed to connect the sheets by gluing in the area of the initial section and the end section.
  • an adhesive with rapid strength build-up can be used, in particular a polymerizing adhesive. It is possible for a first side (top or bottom) of one sheet and an opposite second side (opposite top or bottom) of the other sheet to be processed.
  • a scarfing can be carried out. It can Then, after the processed start and end sections have been moved over each other, they are connected by gluing.
  • This process advantageously ensures that the thickness of the joint is not increased or only increased insignificantly compared to the remaining sheet metal.
  • an appropriate adhesive chemistry By selecting an appropriate adhesive chemistry, a rapid build-up of strength can be achieved and a high-strength connection can be created.
  • This connection can withstand the process forces and advantageously also meets the requirements in terms of heat resistance or compressive strength in the further course of sheet metal processing, for example in a continuous transfer press.
  • the processing unit for producing an interlocking profile of the initial section and the end section is designed with an undercut.
  • An undercut makes it possible to better absorb tensile force.
  • the adhesive connection only serves to join the parts together, whereas the tensile forces are essentially absorbed by the interlocking profile. This results in a higher tensile strength, so that sufficient security against breakage or failure of the sheet metal can be achieved during further processing.
  • the first fixing unit and/or the second fixing unit comprises a hold-down device for clamping sheet metal, preferably across the entire width of the sheet metal.
  • a hold-down device serves to fix or secure the sheet metal by gluing it in place. In other words, pressure is applied to the sheet metal so that it cannot move, in particular not forwards or backwards in the direction of the strip travel.
  • a hold-down device enables efficient implementation and cost-effective realization of the fixing unit.
  • the processing unit is designed to process the initial section and the end section using a grinding, punching, milling, laser, plasma, water jet or sawing tool.
  • the processing unit comprises a tool head that can be moved orthogonally to the direction of travel of the sheet metal.
  • Different methods can be used to process the initial section. It goes without saying that combinations of the methods can also be used.
  • the methods mentioned enable efficient processing or machining of the sheets.
  • efficient profiling or other processing can be carried out. In particular, this results in rapid processing, so that the sheet metal can be continuously forwarded for further processing.
  • the processing unit and the joining unit are implemented in the form of a common tool drive using different tools.
  • a common tool drive can save costs because additional mechanics are not required.
  • a precise processing sequence can be maintained automatically, so that reliability can also be improved. This results in efficient implementation. It is possible to swap the tools or to clamp different tools at the same time, which can then process the start and end sections in parallel or in series if necessary.
  • the delivery unit is designed to forward the sheet metal to a sheet metal storage unit, a continuous transfer press and/or to a punching tool.
  • the sheet metal it is possible for the sheet metal to be transferred first to a sheet metal storage unit, which can be designed, for example, as a roller storage unit with rollers that can be moved against each other or in another way. Continuous forwarding can be achieved or supported by this sheet metal storage unit.
  • the further processing of the sheet metal takes place after the sheet metal storage unit.
  • the sheet metal storage unit is used to ensure a short downtime due to the determination of the initial section and the final section and the connection. This results in further improved efficiency.
  • the feed unit is designed to receive an electrical sheet for a rotor and/or stator sheet stack of an electric motor.
  • the device according to the invention is particularly advantageous when used in the series production of electrical sheets for electric motors, which involves punching and stacking electrical sheets. In this area, a high machine utilization of the corresponding punching and stacking machine is advantageous, since this represents a significant cost factor. This results in further improved cost efficiency.
  • the feed unit is designed to receive the first sheet from a first reel and the second sheet from a second reel.

  • the sheet metal storage device is preferably designed to move the deflection rollers into a fully extended state after the end section has been joined to the start section, in which no buffer is provided and the sheet metal is passed on without bending.
  • the strip storage device is emptied by the deflection rollers moving towards one another. It is particularly advantageous if the deflection rollers are set to a fully extended state during a period in which buffering is not necessary, for example when there is sufficient sheet metal stock and the end of the sheet metal is still a long way off, in order to enable the sheet metal to be forwarded without bending it. Although the sheet metal is not usually damaged by bending, challenges can arise in the further processing unit. To avoid this, the buffer is minimized when it is not needed.
