Description
Technical field
The present invention is mainly used in the corrugated sheet sheet metal component moulding bending complicated and changeable in electric locomotive main converter body structure, is specially a kind of workbench servicing unit for sheet metal component moulding.
Background technology
Development along with sheet metal technology for making, the structure of various parts also becomes increasingly complex, only depend on common moulding Bending Mould to can not meet product design performance need far away, the complex structure of electric locomotive main converter casing particularly, the bending and molding dimensional requirement precision of corrugated sheet structure sheet metal component is high, on same product, need to realize flute profile size height, shape different in size, more particularly with the deep trouth of booster action, narrow groove, make its moulding very difficult.
Manufacture method for corrugated sheet structure sheet metal component has two kinds at present: adopt specially-shaped mould (offset mould) 1., the method is simple and easy to do, but when steel plate thickness and workpiece size are larger, the pressure of equipment is required to strengthen, and when grooved size is less or cannot process (as Fig. 3) when highly larger; 2. when producing in batches and dimension precision requirement is not high, adopt dedicated roller press processing, but the product that such equipment processes mostly cannot meet the mounting structure that has higher dimensional required precision.The method wastes time and energy, and efficiency is lower, and repeatedly moulding bending cumulative errors are larger, and quality is extremely unstable.
Common moulding Bending Mould can not meet the specification requirement of the bending and molding of corrugated sheet structure sheet metal component far away, affected by common bending equipment lathe bed, during bending, labour intensity is large, and production efficiency is low, compact dimensions is inconsistent, and dimensional accuracy, presentation quality do not reach designing requirement.Therefore for as corrugated sheet structure sheet metal component this there is specific (special) requirements, length and grow and the more parts of bending, need a kind of can completing smoothly to realize to this base part the bending machine workbench servicing unit bending, to solve the moulding problem of corrugated sheet structure sheet metal component.
Bender includes for realizing the upper die and lower die of bending function, and the bottom of counterdie is provided with a projection, for being fixed on the workbench of bender.
Summary of the invention
The present invention can not meet product design performance need far away for solving common moulding Bending Mould at present, there is the technical problem that bending is difficult in the bending and molding for corrugated sheet structure sheet metal component particularly, and a kind of workbench servicing unit for sheet metal component moulding is provided.
The present invention adopts following technical scheme to realize: a kind of workbench servicing unit for sheet metal component moulding, comprises a pedestal vertically arranging and the counterdie connecting portion that is vertically connected to pedestal top; The top of described counterdie connecting portion has the groove matching with bender lower die lower end projection.
When the present invention uses, by pedestal, the present invention is fixedly mounted on the workbench of bar folder to (welding or realizes and fixing by bolt), then the counterdie of bar folder is arranged on to the top (projection by groove and counterdie achieves a fixed connection) of counterdie connecting portion of the present invention; Just can be long to the length with specific (special) requirements and parts that bending is more complicated bent as corrugated sheet structure sheet metal component; Due to certain distance has been raised in the position of counterdie, so when the parts to longer bend, can effectively bend and can not cause the interference being bent between parts and bar folder workbench it, solved well this base part in when bending because length is compared with the technical problem of the more bending difficulty causing of long bending.
The present invention is simple in structure, practical, install, debugging is convenient, sturdy and durable, met formed product structure and dimension precision requirement.

The specific embodiment
For a workbench servicing unit for sheet metal component moulding, comprise a pedestal 9 vertically arranging and the counterdie connecting portion 10 that is vertically connected to pedestal 9 tops; Pedestal 9 is connected with bolt 14 with counterdie connecting portion; The top of described counterdie connecting portion 10 has the groove 11 matching with bender lower die 12 lower end projections.
The height of described pedestal 9 is 150mm, and the height of counterdie connecting portion 10 is 100mm.
Described pedestal 9 is evenly placed with bolt holddown groove near a side of bottom.
Workbench servicing unit is installed on bending machine workbench face, bottom according to workbench flute profile size at the side bolt holddown groove of evenly arranging, connecting groove is designed according to counterdie in top, and height is determined according to the size concrete condition of bender impulse stroke and institute's converted products.
Take Fig. 3 as example: wants to realize the moulding of all sites in Fig. 3, after considering rational bending and molding order, auxiliary table has demonstrated huge effect, especially, when carrying out moulding to the 2nd, 4,6,8 roads are curved, on common standard bender, cannot complete.
Fig. 4 ~ Figure 11 by for 1st ~ 8 roads curved moulding demonstrate, further to verify the effect of workbench servicing unit: consider product bending longer dimension, bending required precision is high, moulding position is more, be conducive under complete, the stressed uniform prerequisite of formed product, be chosen in product middle part (first curved 1) and carry out bending and molding (see figure 4), and order completes the bending and molding at curved 2 places of second, now, due to one end longer dimension, common bending machine workbench is the (see figure 5) that cannot avoid and step down.
Fig. 6, Fig. 7 are at a distance of shorter two positions of the curved size in first, second road, (the 3rd, Si road curved) carries out bending and molding, while avoiding subsequent forming, produce and interfere, and bending direction is curved identical with first, second road, in Fig. 7, the effect of auxiliary table has obtained embodiment equally.
Upset product, to the 5th, turn of bilge position, Liu road carries out bending and molding (seeing Fig. 8,9), and more concentrated bathtub construction is completed to processing and forming.
Same method, completes the moulding Bending Processing (seeing Figure 10,11) at sequence number 7,8 positions and other position.
The top of pedestal 9 also has groove, and the side of groove has screw, and groove is put in the bottom of counterdie connecting portion 10, and its position corresponding with screw also has screw, between counterdie connecting portion 10 and pedestal 9, by bolt 14, is fixedly connected; Figure 12 is main TV structure schematic diagram of the present invention, can find out that horizontally disposed adjacent screw spacing a is 150mm for connecting the screw of counterdie connecting portion 10 and pedestal 9, and the Distances Between Neighboring Edge Points b of the screw of outermost side and pedestal 9 is 30mm; Screw center and pedestal 9 top spacing c=30mm.
Figure 13,14 has been for having adopted the structural representation of the product processing after device of the present invention, and the structure that can find out these two parts is more complicated all, and traditional bender is difficult to accurately processing.
