Description

Technical Field

[0001] The invention relates to the field of riveting and welding embedded parts manufacturing, and mainly relates to a tooling die and a manufacturing method for embedded parts of reaction wall and reaction pedestal loading holes. Background Art

[0002] The reaction wall and reaction pedestal are important facilities in the seismic laboratory for quasi-static or quasi-dynamic tests of various structural components and structural systems. This facility can carry out two-dimensional pseudo-dynamic test research on structures and components. Many loading holes are embedded in the concrete structure of the reaction wall and reaction pedestal. The loading hole is a steel pipe with square steel plates welded at both ends. The steel plates at both ends of the loading hole are flush with the surface of the reaction wall or reaction pedestal. The loading hole is the connection channel between the test component and the reaction wall reaction pedestal, and is also the main part of force transmission. The verticality and flatness of the loading hole end plate are extremely high (designed to be millimeter level). The length error is controlled within <±0.5mm, the end plate flatness error is <1mm, and the verticality error between the center of the loading hole and the steel plates at both ends is <±1mm.

[0003] High-precision loading hole embedded parts are generally processed and manufactured in a mechanical processing plant. The loading hole steel pipe and the steel plates at both ends are placed in the loading hole production tooling mold in turn, and all indicators are checked to be qualified. The end plate and the steel pipe are symmetrically spot welded; after the loading hole indicators are re-tested and qualified, the weld is fully welded to achieve the purpose of mass production.

[0004] The usual practice for making tooling molds for loading holes is: on a base, two end baffles and positioning plugs are set according to the length of the loading hole, one end is a fixed baffle and positioning plug, and the other end is an adjustable clamping device baffle and positioning plug. The positioning plug, loading hole, and the vertical line of the center of the baffle are coaxial. However, in actual use, the fixed baffle and positioning plug at one end are prone to precision deviation after mass production of loading hole iron parts. During regular mold calibration, if precision deviation is found, it is necessary to adjust the fixed end plate and positioning plug, and the time used is almost the same as remaking a positioning baffle and positioning plug. It has a certain impact on the production progress and the accuracy of loading hole production.

[0005] Through research, it was found that adjustable clamping device baffles and positioning plugs are used at both ends of the loading hole production tooling to facilitate the inspection and correction of the mold accuracy, eliminate the difficulty in correction due to the fixed baffle and positioning plug at one end, and thus the impact on the production progress and loading hole production accuracy. A reaction wall reaction pedestal loading hole embedded part production tooling mold can solve the above problems. Summary of the invention

[0006] The purpose of the present invention is to make up for the defects of the prior art, provide a tooling mold and a manufacturing method for the embedded parts of the reaction wall and reaction pedestal loading hole, ensure the accuracy of the single-piece manufacturing of the loading hole, enable the single-piece loading hole to be mass-produced, and significantly improve the manufacturing speed of the single-piece loading hole.
