4results about How to "Reduce bending difficulty" patented technology

This invention discloses an automated processing line for bending and forming aluminum alloy crash beams, comprising a feeding device and a bending and forming device. A feeding conveyor belt transports hollow aluminum alloy profiles through an open opening to a profile support in a heating chamber. Each set of heating resistance wires, driven by a corresponding resistance wire drive cylinder, is inserted into the hollow aluminum alloy profile to heat it. The transfer assembly transports the heated hollow aluminum alloy profile to the bending and forming device. The bending and forming device bends the hollow aluminum alloy profile into an aluminum alloy crash beam. The feeding device not only automatically feeds the profile to the bending and forming device but also efficiently preheats the hollow aluminum alloy profile, thereby improving its plasticity, significantly reducing the bending difficulty of the profile, improving processing accuracy, and ultimately greatly increasing the yield rate of the aluminum alloy crash beams.

This invention discloses a method for fixing tubular components with adhesive, aiming to solve the problem of adhesive and tubular workpieces protruding above the product surface during the adhesive filling process, affecting product quality. The invention includes the following steps: S1, injecting adhesive into a groove on the product to be filled, covering the bottom of the groove with a base layer of adhesive; S2, inserting the tubular workpiece into the groove; S3, pressing a clamping fixture onto the tubular workpiece, ensuring the highest point of the tubular workpiece is below the surface of the product; S4, allowing the base layer of adhesive to cure; S5, removing the clamping fixture; S6, injecting side adhesive into both sides of the tubular workpiece at the groove opening to form side adhesive, and smoothing the adhesive surface to make it flat; S7, allowing the side adhesive to cure. This method for fixing tubular components with adhesive in this patent application reduces the flatness requirements after bending the tubular components, thereby reducing the difficulty of bending the tubular workpieces. During the adhesive filling process, the adhesive and tubular workpiece will not protrude above the product surface, ensuring product quality.

This invention discloses a surface-mount capacitor and its manufacturing process. The surface-mount capacitor includes: an upper shell, a lower shell, a first capacitor body, a second capacitor body, a first metal lead, and a second metal lead. The upper shell and the lower shell are connected to form a sealed chamber. The top surfaces of the first capacitor body and the second capacitor body are connected in series via a metal sheet. The bottom of the lower shell has a first through hole and a second through hole. One end of the first metal lead is welded to the bottom surface of the first capacitor body, and the other end of the first metal lead passes through the first through hole and extends to the outside of the sealed chamber. One end of the second metal lead is welded to the bottom surface of the second capacitor body, and the other end of the second metal lead passes through the second through hole and extends to the outside of the sealed chamber. The surface-mount capacitor and its manufacturing process of this invention optimize the welding steps and reduce the difficulty of lead bending.

The invention provides a bending structure, an insertion part and a medical catheter, and relates to the technical field of medical instruments. The device comprises a lining bending pipe and a traction rope, the lining bending pipe is of a pipe body structure which is continuously arranged in a closed mode in the circumferential direction, the far end of the traction rope is fixedly connected relative to the far end of the lining bending pipe, and the traction rope can apply traction force to the lining bending pipe; the action direction of the traction force deviates from the axial direction of the lining bent pipe. Compared with the prior art, the bending starting state can be optimized, the driving force needed by bending operation is reduced, the difficulty that the whole catheter achieves the bending action is reduced, and therefore the bending response performance and the control efficiency are improved.
