TH95125A - Penetration methods and preforms that use hydroforming and hydroforming parts and structures. - Google Patents

Abstract

DC60 This invention was made with the aim of not using short pipe assemblies when mounting brackets. Threaded into the hydroforming component. Prevents increasing formation difficulty Hydroforms for bolting. Extend the length of the nut so that it can be strong. Enough when mounting the bolts. And makes it applicable to hydroforming parts that It is thin-walled and consists of inserting a metal tube into a split formwork with a penetrating hammer that can Has been a motion perpendicular to one axis of the metal tube being inserted or in an inclined direction with a slimmer face than the middle. And around the front part there is a screw pad with a large inner diameter Than the outer diameter of the front part and smaller than the outer diameter of the middle part, forming a hydroform And after that make the drill bit head moving forward for drilling Go through the part of the hydroforming part and push the nut with the arranged center part. Behind the nuts and embed the keys in the metal tube This invention was done with the aim of eliminating the use of short tube assemblies when the brackets were attached. Threaded into the hydroforming component. Prevents increasing formation difficulty Hydroforms for attaching the keyboard Extend the length of the spline so that it can be strong. Enough when mounting the bolts. And makes it applicable to hydroforming parts that It is thin-walled and consists of inserting a metal tube into a split formwork with a penetrating hammer that can Has been a motion perpendicular to one axis of the metal tube being inserted or in an inclined direction with a slimmer face than the middle. And around the front part there is a screw pad with a large inner diameter Than the outer diameter of the front part and smaller than the outer diameter of the middle section, forming a hydroformed And after that make the drill bit head moving forward for drilling Go through the part of the hydroforming part and push the nut with the arranged center part. Behind the nuts and the keys are embedded in the metal disc

Claims (1)

1. A penetrating method that uses a hydroforming consisting of a dl Into a split formwork with a penetrating drill head that can receive motion perpendicular to one of the axes of the Metal tubes that have been inserted in or in an inclined direction. The front part is narrower than the middle and around the front part has a threaded nut with a larger inner diameter than the outer diameter of the front. And smaller than the outer diameter of the middle part Apply internal pressure on metal pipes and pressure. Axial direction of pipes or internal pressure for forming hydroforms. Make the drill bit The piercing moves forward to penetrate a portion of the metal tube by the front end of the drill head later, causing the nut to move forward while pushing the center part arranged behind the nut The perforation device is pushed to the inner surface of the metal tube and the nut is embedded in the metal tube. The metal is attached and the internal pressure and axial pressure pathway. The penetrating prefabrication of hydroforms is particularly characterized by having a perforation head. It can be moved perpendicular to one axis of the metal tube inserted or in an inclined direction, having a narrower face than the middle. And has a knob with inner diameter larger than the diameter The outside of the forend around the fore and smaller than the outer diameter of the center of the drill bit is responsible for penetrating the metal tube by the fore with a subsequent upward motion, then pushing the peripheral The holes are penetrated by the nut to the inner surface of the metal tube and are embedded. The hydroforming as described in Clause 2 is characterized by the presence of a secondary hammer around the front of the perforation hammer and the inter-section. The middle between the nut and the perforation hammer. 4. Hydroforming part with an opening in the lateral wall of a metal pipe. The hydroforming part is unique in that the opening part has a Convex that extends to the inner surface 5. The hydrophobic parts, as outlined in Clause 4, are characterized by The keys have a horizontal cross-section shape, polygon, or oval or A figure of a horizontal cross-section that is a contour of a line and a mix of curves or cross-sections. 6. The hydroforming parts described in claim 4 or 5 are unique. Where the nut has a horizontal cross-sectional shape that differs in the axial direction from the nut 7. the hydroforming part, as specified in Clause 4 to 6, one of It is characterized by that the nut is embedded in the inner surface of the tube from the surface. Outside of the metal tube 8. Any of the aeroforming parts as specified in Claims 4 to 7. It is characteristic in that the convex part has a hole at the front end that is smaller than the outer diameter of the The nuts and, with the protruding portion of the nut on the inner surface side 9. the hydroforming part as specified in Claims 4 to 9, any of Characteristically, the nuts have indentations, concave or convex on the side surfaces. 1 0. Hydroforming part as specified in Claims 4 to 9. It is unique in that the nuts and bolts are welded together. 1 1. A structure characterized by being bolted into the same unit as its parts. Form the hydroform as described in any of Clause 4 to 10.
