  • Patent number: 10792727
    Abstract: Devices, systems and methods are disclosed which relate to a wire bending apparatus capable of both on and off-plane nose and mandrel bends. Exemplary embodiments of the present invention incorporate a center turret cluster with a plurality of radii possible, a nose-bending mandrel, and a mandrel-bending mandrel. This apparatus forms a bending head that is attached to a CNC wire bending machine. This combination allows increased flexibility in forming complex wire forms and cuts down secondary operations, such as operations from robot arms, sometimes associated with CNC wire bending. In addition, the turret cluster position in the center allows for bending support with mandrel bends or nose bending on the back side of the bending head, usually 180 degrees away from the normal bending area. This allows the manufacturing of double end-loop forms without the addition of external clamps or robotic manipulation.

In one optional implementation, one beam is high powered and acts as a deposition beam that melts a metal feed stock material which is delivered to a deposition zone and onto a work surface and the second electron beam is a low power electron source. The second electron beam acts as an interrogating source that generates an electron beam which interacts with the deposited material. The second electron beam may be active after material is deposited and provides post-deposition in-situ metrology. Various signals generated by this second beam/material interaction are collected and used to provide information about the melted and deposited material.

  • Patent number: 10792761
    Abstract: A pressing system for a laser joining system for pressing together parts to be joined (storage cell, base plate) in the area of a joining point, includes a receptacle for accommodating the parts to be joined, a pressing element for locally pressing together the parts to be joined, in the area of the joining point, and a positioning system for the relative positioning of the pressing element and the receptacle and for pressing together the parts to be joined, during the joining process. The positioning system includes a parallel positioning device for the relative positioning of the receptacle and the pressing element in parallel to a plane (E), and an oblique positioning device for the relative positioning of the pressing element and the receptacle obliquely, in particular transversely, with respect to the plane (E) and for pressing together the parts to be joined, during the joining process.

  • Patent number: 10792764
    Abstract: Methods for manufacturing reinforced structural components are described. The methods include providing a previously formed steel structural component having a thickness of 0.7 mm to 5 mm. In a reinforcement zone of the structural component, locally depositing a material on the structural component to create a local reinforcement with a minimum thickness of 0.2 mm, wherein locally depositing a material on the structural component includes supplying a metal powder to the reinforcement zone, and substantially simultaneously applying laser heat to melt the metal powder and create the reinforcement by drawing specific geometric shapes on the structural component with the metal powder and the laser heating. The disclosure further relates to a reinforced component obtained using such methods.

  • Patent number: 10792765
    Abstract: Variations in the quality of starting end parts of cladding layers are reduced. An aspect of the present disclosure is a method for forming a cladding layer in which a cladding layer is formed by starting to supply a metal powder onto a base material by changing a supply instruction to an on-state, and irradiating the metal powder with a laser beam according to a laser output pattern corresponding to the supply instruction. The method includes, before forming the cladding layer, acquiring a fluidity of the metal powder, and changing the laser output pattern according to the acquired fluidity.

  • Patent number: 10792766
    Abstract: The invention relates to additive manufacturing field and laser shock peening (LSP) field, in particular to a combined apparatus for layer-by-layer interactive additive manufacturing with laser thermal/mechanical effects. In the apparatus, a LSP module and a SLM module operate in alternate so as to perform LSP for the formed part in the forming process of the formed part, and thereby a better strengthening effect of the formed part is achieved. The invention effectively overcomes the challenges of “shape control” against deformation and cracking of the formed parts incurred by internal stress and “property control” against poor fatigue property of the formed parts incurred by metallurgical defects during additive manufacturing, improves fatigue strength and mechanical properties of the faulted parts, and realizes high-efficiency and high-quality holistic processing of the formed parts.

  • Patent number: 10792767
    Abstract: A laser preheating control method is applied to a laser preheating control device. When a cutter processes a workpiece along a process path, a laser source of the device is provided to output a laser beam to the workpiece for selectively forming a laser spot on the workpiece surface. And according to a movement direction of the cutter, a laser controller of the device is provided to form the laser spot only on a preheating region of the workpiece, where in front of the cutter in the process path, for preheating the workpiece in the preheating region. As a result, the laser spot will not repeatedly heat the workpiece behind the cutter in the process path, and the qualitative change of the workpiece caused by repeating heating is preventable.
