Abstract
A forming die for a spherical surface stainless steel plate comprises a bottom plate, a lower backing plate, a concave die, a convex die, a convex-concave die, a top plate and an upper backing plate. The concave die is installed on the bottom plate, the lower backing plate is arranged between the concave die and the bottom plate, the convex die is installed in an inner cavity of the concave die in a sliding fit mode, and the convex face of the convex die faces upwards. The convex-concave die is installed on the top plate, the upper backing plate is arranged between the convex-concave die and the top plate, and the concave face, matched with the convex face of the convex die, of the concave die is opposite to the convex face of the convex die. Hole sites are arranged in the top plate and the bottom plate and used for fixedly connecting a top plate and a bottom plate of a hydraulic machine. The forming die for the spherical surface stainless steel plate is scientific in design, simple in structure, convenient to operate, low in part suppressing resilience amount, stable, reliable, high in strength, fatigue and abrasion resistant, high in working efficiency and low in cost.
Description
Technical field
The present invention relates to a kind of bearing sphere steel plate forming mould, relate in particular among a kind of spherical bearing that is applied to the civil engineerings such as bridge, building between the mould of sphere corrosion resistant plate of spherical crown steel liner plate welding.
Background technology
Along with the antidetonation of bridge, building and the development of seismic isolation technology, spherical bearing application is more and more extensive, comprise that common spherical bearing, E shaped steel subtract shock insulation ball shaped steel bearing, C shaped steel and subtracts that shock insulation ball shaped steel bearing, hyperboloid subtract shock insulation ball shaped steel bearing, friction pendulum subtracts shock insulation ball shaped steel bearing etc., this type of bearing exist common ground be in the middle of spherical crown liner plate have one side at least for sphere.The protruding sphere of standard GB/T 17955-2009 regulation bearing spherical crown liner plate, can adopt coated corrosion resistant plate or durionise to process, because chrome-plated process requires quite high spherical-machine machining accuracy as prerequisite, chrome-plated process process is complicated simultaneously, cost is higher, for the bearing on heavy corrosion environment bridge, should adopt coated stainless steel slide plate.The critical technological point of the coated stainless steel slide plate of the protruding sphere of spherical crown liner plate is the compressing of sphere corrosion resistant plate, and the sphere stainless steel mould using at present exists following not enough place:
1. mould is except the basic forming members such as die, punch, punch-die, also must adopt be provided with bead blank holder, provide the flexible member of enough pressure as spring, rubber etc., mould structure is complicated, die cost is high;
2. the part springback capacity of compacting is large, unstable, thereby exists and cause defective work compared with macroscopic-void while causing sphere corrosion resistant plate and the welding of spherical crown liner plate.
Summary of the invention
The technical problem to be solved in the present invention is, provides a kind of simple in structure, efficiency is high, cost is low sphere corrosion resistant plate mould, to overcome the existing above-mentioned deficiency of prior art.
The technical scheme that the present invention takes is: a kind of sphere corrosion resistant plate mould, comprises base plate, lower bolster, die, punch, punch-die, top board and upper padding plate; Described die is arranged on base plate, between die and base plate, lower bolster is set, and described punch is slidably installed at the inner chamber of die, and the convex surface of punch upwards; Described punch-die is arranged on top board, between punch-die and top board, arrange and upper padding plate, the concave surface that punch-die matches with the convex surface of punch is relative with the convex surface of punch, and described top board and base plate are provided with the connecting hole position being connected and fixed for the top board with hydraulic press and base plate.
Its further technical scheme is: the convex surface height of the surrounding edge aspect ratio punch of described die is high, and vertical surface and the bottom surface intersection of die inner chamber surrounding edge are provided with chamfering; The intersection of described punch-die side and sphere is provided with chamfering.
Its further technical scheme be: between described die and punch-die, be provided with certain gap.
Described base plate and lower bolster are provided with the through hole for the push rod reeve of hydraulic machine.
Described die, punch-die and punch adopt high strength steel material to make.
Owing to adopting technique scheme, the present invention's sphere corrosion resistant plate mould has following beneficial effect:
1. the present invention's sphere corrosion resistant plate mould adopts die cavity binder mode, design science, easy to operate, without the flexible members such as blank holder (plate) and spring, rubber are set, thereby greatly simplify mould structure, reduction Mold Making cost;
2. the present invention's sphere corrosion resistant plate mould operating efficiency is high, and intensity is high, endurance, wear-resistant, long service life, economical and practical, and the sphere corrosion resistant plate springback capacity of its compacting is low, reliable and stable.
Below in conjunction with drawings and Examples, the technical characterictic of the present invention's sphere corrosion resistant plate mould is further described.
