Description
Technical field
The present invention relates to a kind of sheet metal edge thickening machine.Be mainly used in the production technology of cutter cutter embryo, steel hoe, also can be used for need be to other machining technique field of metal-sheet edges thickening.
Background technology
People are in order to improve labor productivity, and the cutter production industry has generally been broken away from traditional steel billet and forged operation by hand, then adopt the steel plate direct mechanical to cut moulding process.But existing machinery cuts in the molding technology thereof, and the machining process of kitchen knife cutter blank is: at first, select for use the steel disc hot rolled coil as raw material and with straightener hot rolled coil to be pulled into straight band, with shearing machine straight band is carried out lateral shear, cut into straight piece; With punch press straight piece is carried out punching press, form blank; Secondly, again blank is carried out heat after; Partly forge with the blade of belt drop hammer again, blank is broken into base just the high temperature blank; Perhaps, could form base just through the wear down operation; Afterwards, utilize punch press that first base is cut into slices according to the blade shape again, form cutter blank; But owing to consider to produce the cost problem with the material steel plate, the thickness of this cutter blank knife back is often done to such an extent that equate with blade middle part section thickness, and thin partially; It is abundant that this cutter product can not show a candle to the cutter knife back that traditional-handwork forges.The cutter blade section that traditional-handwork forges be " wedge " good hand touch with, stressed, for example: the kitchen knife that uses traditional-handwork to forge cuts open the fish head, needs to pat knife back operation, the thick cutter section back of the body is just more stressed.For this reason, also the someone attempts that existing machinery is cut the cutter blank that molding technology thereof makes and carries out the thickening of knife back section part, makes mach cutter and traditional-handwork forge cutter and has good hand touch usefulness, stressed effect equally.For this reason, prior art has occurred clamping the cutter hub workpiece with mould, and the tool setting back portion uses heating to forge or process for upsetting is accomplished in cold roll-in.
The shortcoming of prior art processes is: the tool setting back portion uses forge hot to beat, and energy consumption is high, and oil smoke is heavy, pollutes big; And no matter be to use heating to forge or roll operation, mould all adopts spiral to support crowded to the clamping of cutter blank workpiece or two kinds of technical schemes of hydraulic jack extrusion realize; Aforesaid operations is because the cutter blank workpiece will constantly bear huge forging or the roll-in impulsive force; The employing spiral supports crowded technical scheme, and the huge impact masterpiece is used in and is easy to cause a tooth distortion, newspaper damage on the screw thread; Therefore, during field operation, need constantly the adjustment clamping gap or change screw mandrel, thereby influence the machining accuracy and the speed of production of cutter blank, production cost also increases simultaneously.To adopting hydraulic jack extrusion technical scheme, because " soft " characteristic of hydraulic jack compressive force, it is unstable to cause mould to clamp the chucking power of cutter hub workpiece, finally can influence the machining accuracy of cutter blank, causes percent defective to increase.
Summary of the invention
Technical problem to be solved by this invention is that a kind of sheet metal edge thickening machine is provided.So that metal-sheet edges can form the webbing that a section is wedge automatically after roll-in.This equipment is stable to the chucking power of metallic plate or cutter blank or steel hoe workpiece; Absorb the roll-in impulsive force dexterously, overcome " soft " characteristic of hydraulic jack compressive force, improved processing precision of products.The degree of the production automation simultaneously is high, and long service life need not heat, and energy consumption is low, and is pollution-free.
Technical scheme of the present invention is following: a kind of sheet metal edge thickening machine, mainly form by support, sheet metal forming mould, clamping and positioning device and rolling device; Rolling device joins through the piston rod of first hydraulic jack above the sheet metal forming mould, and the level that makes it rolls motion back and forth; Described clamping and positioning device comprises decides fixture block, moving fixture block, fore-set, bearing plate, contract piece and second hydraulic jack; The sheet metal forming mould is placed in moving fixture block and decides between the fixture block; Moving fixture block is fixedly connected bearing plate through fore-set, the pull bar of the fixing band silking in bearing plate middle part; There is the baffle plate of through hole at welding one middle part on support, when the working face of the working face of bearing plate and baffle plate relatively near the time, above-mentioned pull bar passes through hole and is inserted in return spring by the nut locking; Above-mentioned contract piece is connected on the piston rod of second hydraulic jack, and the contract nose part is inserted between the working face of bearing plate and baffle plate push away bearing plate to squeeze; Described first hydraulic jack, second hydraulic jack are connected hydraulic pump through oil pipe with the hydraulic oil combined control valve.Described rolling device mainly by running roller, fork pulls out and two guide beams are formed; Two guide beams laterally arrange; The root that fork pulls out and the piston rod of first hydraulic jack are fixed; Described running roller is installed in the middle part of a main shaft, and two legs that fork pulls out are passed at main shaft two respectively, the extension at its two ends, and the bottom surface with two guide beams contacts respectively; Described two guide beam ends are respectively equipped with the running roller pressure-adjusting screw.
Further, the extension at above-mentioned main shaft two ends is installed sliding bearing respectively and is contacted with the bottom surface of two guide beams.
The present invention adopts above technical scheme; Between the clamping and positioning device and second hydraulic jack, the contract piece is set; Utilize the mechanics switching-over and the catabiotic principle of face contact friction on contract piece inclined-plane; The impulsive force that the rolling device roll-in is produced absorbs dexterously, has solved " soft " characteristic of prior art hydraulic jack compressive force, has improved processing precision of products.While main consumable part of the present invention-contract piece; Push away frictional force and be out of shape or loss though constantly bear in process of production to squeeze; But because the contract piece is to connect on the piston rod of second hydraulic jack; And the piston rod of well-known hydraulic jack has stroke adjustment characteristic, and therefore, distortion of contract piece or waste are compensated from the piston rod of hydraulic jack automatically; Can guarantee in the contract piece life span accuracy of processing fully.So production automation degree of the present invention is high, working (machining) efficiency is high, long service life, and energy consumption is low, and is pollution-free.
