Abstract
The utility model relates to nonferrous metallurgical industry processing equipment, in particular to a silver ingot shearing machine capable of protecting silver ingot against upwarp. The silver ingot shearing machine capable of protecting silver ingot against upwarp comprises a workbench frame and a frame-shaped support. A hydraulic cylinder is arranged on the upper portion of the frame-shaped support, a piston head of the hydraulic cylinder is arranged downwards, a knife rest is installed on the piston head, an upper shear is installed on the knife rest, a lower shear right opposite to the upper shear is installed on a platform face of the workbench frame, and an ingot containing device is arranged on the front side of the lower shear. The silver ingot shearing machine is characterized in that a silver ingot pressing device is additionally arranged on the knife rest; the silver ingot pressing device comprises a suspension arm welded to the knife rest and extending forwards and a lifting rod installed on the suspension arm; a limiting nut is arranged at the upper end of the lifting rod, and a pressing plate is welded to the lower end of the lifting rod, and a compression spring is installed on the lifting rod. The silver ingot shearing machine overcomes the defects that trimming burrs exist on notches of a silver ingot machined by an existing shearing machine and are not irregular, inclined faces are formed easily, and the appearance quality of the silver ingot and silver ingot uniform standard weight are affected. The silver ingot shearing machine is mainly used for shearing and forming the silver ingot.
Description
Technical field
The utility model relates to the colored metallurgical industrial process equipment, a kind of anti-silver ingot cutter that sticks up of especially processing with silver ingot.
Background technology
" silver ingot " GB/T4135-2002 requirement that all is difficult to be up to state standards on 15kg silver ingot presentation quality of current domestic noble metal industry, main cause is exactly that silver ingot when casting weight is difficult to control and silver ingot sheared edge is difficult to reach the technology requirement, the silver ingot shearing quality depends on the option and installment of silver ingot shearing equipment to a great extent, it is reported that the more domestic same industry also waters deadhead at device processes silver ingots such as using the power hacksaw bed, inefficiency and easily cause precious metal losses, silver ingot weight is difficult to control, the saw incision has burr, irregular, tangent plane fineness is low etc. manyly affects presentation quality and the requirement of silver ingot weight.
Forefield producer starts to process silver ingot casting head with the silver ingot cutter, existing silver ingot cutter includes Working gantry, frame support is housed above Working gantry, hydraulic cylinder is equipped with on the top of frame support, is furnished with hydraulic power supply outward, the piston head of hydraulic cylinder is arranged downwards, knife rest is housed on piston head scissors is installed, on the Working gantry table top over against on scissors lower scissors is installed, be equipped with and put ingot device in the front side of lower scissors, the outstanding problem that existing silver ingot cutter exists is: during shearing, be subject to the impact of scissors pressure, the silver ingot afterbody easily upwarps, so very easily make the silver ingot otch produce the burr flash, otch is irregular, easily form inclined-plane, thereby affect the unified standard weight of product appearance quality and silver ingot.
Summary of the invention
The purpose of this utility model will solve existing silver ingot cutter exactly in shear history, and silver ingot easily upwarps, thereby affects the problem of product appearance quality and unified weight, and a kind of anti-silver ingot cutter that sticks up is provided.
Concrete scheme of the present utility model is: for existing silver ingot scissor machine, improved, it has Working gantry, frame support is housed above Working gantry, hydraulic cylinder is equipped with on the top of frame support, is furnished with hydraulic power supply outward, the piston head of hydraulic cylinder is arranged downwards, knife rest is housed on piston head scissors is installed, on the Working gantry table top over against on scissors lower scissors is installed, be equipped with and put ingot device in the front side of lower scissors, it is characterized in that: add the silver ingot hold down gag on knife rest, this device includes the cantilever that is welded and extends forward on knife rest, have vertically arranged through hole at the cantilever front end, be coated with elevating lever in through hole, stop nut is equipped with in the upper surface that cantilever is stretched out in the upper end of elevating lever, the lower end of elevating lever is downwards along stretching and the pressing plate that has been welded in end, between pressing plate and cantilever, Compress Spring is housed on elevating lever.
The pressing plate limit inferior position of the lower end of elevating lever described in the utility model is higher than scissors mouth 0-6mm.
The utility model is owing to having installed the silver ingot hold down gag on the knife rest at the silver ingot cutter additional, when silver ingot is sheared, pressing plate in hold down gag is under spring action, silver ingot is compressed, effectively prevented upwarping of silver ingot, thereby guaranteed that the silver ingot otch is smooth, unified, made silver ingot product appearance quality good, weight standard is unified.
