Description
Technical field
The utility model relates to a kind of mould, and especially a kind of composite die of processing the arc sheet metal component belongs to sheet metal component die for processing technical field.
Background technology
In sheet metal component processing, modal is exactly to utilize forcing press that sheet metal component is carried out bending machining, for example, and to the bending machining of the sheet metal component 4 shown in the accompanying drawing 1.For the at one end crooked 1/4 circular-arc sheet metal component that is of this kind needs, all use the bending mould shown in accompanying drawing 2 to process.This bending mould comprises lower bolster 100, die 101, punch 102, holding pad 103, ejector beam 104; Lower bolster 100 is fixed on the workbench of forcing press; Die 101 be fixed on lower bolster 100 directly over; Holding pad 103 places in the die 101; Ejector beam 104 passes lower bolster 100 and die 101, and is fixed on the bottom of binder version 103; Punch 102 is positioned at die 101 tops, and the top of punch 102 is fixed on the slide block of forcing press.Add man-hour, ejector beam 104 to concordant with the right side of die 101, places holding pad 103 jack-up on the end face of die 101 with blank, and the slide block of forcing press moves down, and drives punch 102 and moves down; Punch 102 and holding pad 103 are jointly with blank holding, and punch 102, die 101 and holding pad 103 are gradually with the sheet bending moulding.
Because crooked central angle is little; Deformed region is also smaller, and the position that adds the circular arc in man-hour is difficult to control, and because the angle influence springback; The sheet metal component of processing can not satisfy the requirement of shape; After bending machining is accomplished, also need carry out manual synchronizing to sheet metal component with the holotype model, could guarantee the arc accuracy of sheet metal component like this.So not only when bending, need reserve certain processing capacity, and influence the progress of processing greatly, reduce production efficiency, also waste a lot of manpowers.In addition, the processing capacity of reservation also needs to remove behind manual synchronizing again, makes that the circular arc processing of sheet metal component is very complicated, has both increased operating personnel's working strength, and product quality that processes and precision also can not get effective assurance.
The utility model content
The utility model purpose is to provide a kind of for the deficiency that overcomes prior art to process at one time, and increases work efficiency, and reduces labour cost, guarantees that effectively compound die is used in the arc sheet metal component processing of machining accuracy.
For achieving the above object, the technical scheme that the utility model adopts is: compound die is used in a kind of arc sheet metal component processing, comprises lower bolster, fixed block, crooked die, crooked punch, cuts off punch, unloading block, ejector beam and discharge arm; Said lower bolster is fixed on the workbench of forcing press; Said fixed block be fixed on lower bolster directly over; Lower bolster and fixed block are passed in the top of said ejector beam, and are fixed on the bottom of unloading block; Said unloading block is two, all is positioned at the top of fixed block, and all fits with the end face of fixed block in its bottom surface; The end face of said unloading block is cambered surface, and its radian requires to decide according to the bending of sheet metal component; Also be provided with the cut-out punch between said two unloading block; Said two unloading block are placed in opposite directions, and its cross section forms an incomplete semicircle shape; Said cut-out punch passes fixed block, and is fixed on the lower bolster; The end face of said cut-out punch is higher than the minimum point of unloading block cambered surface; Said crooked die is fixed on the fixed block; Said unloading block is arranged in crooked die, and two unloading block of ejector beam control move up and down in crooked die simultaneously; Said crooked punch is two, lay respectively at two unloading block directly over; The top of said crooked punch all is fixed on the slide block of forcing press, and also is provided with discharge arm between two crooked punch; The top of said discharge arm is fixed on the forcing press.
Preferably, said discharge arm is connected with knockout rod through contiguous block; Said knockout rod is fixed on the forcing press; The top of said crooked punch has and the corresponding chute of contiguous block.
Preferably, the end face of said cut-out punch exceeds the minimum point 4～6mm of unloading block cambered surface.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
Compound die is used in a kind of arc sheet metal component processing of the utility model scheme, processes at one time two sheet metal components, with bending machining, correction processing and cut-out processing; Piece together time processing; Improve operating efficiency greatly, reduced labour cost, practiced thrift great amount of manpower; Also effectively guaranteed the quality and the machining accuracy of product, brought very big economic benefit to production firm.
