Abstract
The utility model relates to an unloading device after hole flanging in digital camera component production, designed to solve the problems of over-intension of a discharging needle in the prior unloading device and deforming of the flanging hole in unloading process, comprising an upper module and a lower module, characterized in that the upper module is provided with a discharging needle solid plate which is provided with a discharging needle and a depression thimble, and simultaneous with discharging of the discharging needle, the depression thimble resists against the lower module with pressure sharing effect, thereby making the discharging needle discharge slowly and preventing damage on the flanging hole. The utility model is also applicable to discharging after the hole flanging in other thin type metal component production.
Description
(1) technical field: the utility model relates to the processing mold of hardware, is specifically related to the device for discharging behind the thin metal member piercing and flanging.
(2) background technology: the device for discharging behind the existing digital camera thin metal structure manufacture flange hole as shown in Figure 1, thin metal member 7 is a upper mould piece with top, below is module down.Upper mould piece is connected and composed by upper module 3, middle module 4, lower module 6, and 5 for being installed on the activity discharging pin in the upper mould piece, and 2 are the discharging needle spring, and 1 is fixed screw.Following module comprises that the module 11,13,9 of connection is the workpiece backing plate, and 10 is towards the pin fixed head.Workpiece backing plate 9 flexibly connects with pin 12, and spring 14 is installed on the below of pin 12, and 15 is the spring fixed screw.Device shown in Figure 1 has been made the flange hole to member 7, and when die sinking and discharging, patrix is toward rising, workpiece lower bolster 9 is past thereupon the rising under the effect of spring 14, leave the flange hole of hardware 7 towards pin 8, meanwhile, discharging pin 5 is under the effect of spring 2, walk downward, because the elastic force of spring 2 is very big, when discharging pin 5 withstands on the flange bore edges loading and unloading material of hardware 7, has certain impulsive force, Chang Yi makes the edge deformation in slim member flange hole, influences product quality.
(3) summary of the invention:
The purpose of this utility model provides the device for discharging after another kind is used for digital camera structure manufacture flange hole, it can solve above-mentioned existing device for discharging shown in Figure 1 when making behind the flange hole discharging on the slim member of digital camera, the discharging pin be easy to make slim member flange hole edge deformation, influence the problem of product quality.
The technical solution of the utility model is as follows:
Device for discharging behind the digital camera structure manufacture flange hole, it comprises that upper mould piece reaches module down, upper mould piece comprises the upper module of connection, middle module and lower module, device discharging pin and energizing spring thereof in upper mould piece; Following module comprises the upper module and the lower module of connection, device is towards pin fixed head and workpiece backing plate in the following module, in the pin fixed head, fixedly mount the pin that dashes that passes the workpiece backing plate, installation activity pin and energizing spring thereof in the following module, described workpiece backing plate and movable pin flexibly connect; It is characterized in that device discharging pin fixed head in the middle module of upper mould piece, discharging pin and decompression thimble are installed in the lower end of discharging pin fixed head, described decompression thimble and discharging pin penetrate the lower module of upper mould piece respectively, the length of decompression thimble is installed energizing spring greater than the length of discharging pin in the upper end of discharging pin fixed head.
Because the fixed head of discharging pin is installed in upper mould piece, on discharging pin fixed head except that the discharging pin is installed, the decompression thimble of length greater than the discharging pin also is installed, during discharging, be added on of the effect of the spring force of discharging pin by discharging pin fixed head and decompression thimble, the elastic force that is added on the discharging pin is disperseed, the discharging pin is played depressurization, during discharging, no longer there is impulsive force in discharging at the flange bore edges of workpiece, but slowly afterburning, efficiently solve that the discharging pin makes the flange bore deformation in the prior art, reduce the problem of product quality and qualification rate.
(4) description of drawings:
Fig. 1 is for having the device for discharging after digital camera thin metal member is made the flange hole now;
Fig. 2 is a thin metal member longitudinal sectional view;
Fig. 3 is in the structure chart of matched moulds state for the utility model;
Fig. 4 is in the structure chart of discharging state for the utility model;
Fig. 5 is in the structure chart of state after the discharging for the utility model.
(5) specific embodiment:
See Fig. 3,7 is slim tool member, and member 7 is a upper mould piece with top, with the lower part is following module, and upper mould piece comprises upper module 3, middle module 4 and the lower module 6 that connects with screw, device discharging pin 5 and energizing spring 2,1 thereof are its hold-down screw in upper mould piece.Following module comprises upper module 11 and the lower module 13 that connects with screw, device is towards the backing plate 9 of pin fixed head 10 and tool member 7 in the following module, what workpiece backing plate 9 was passed in fixed installation in the pin fixed head dashes pin 8, also installation activity pin 12 and energizing spring 14,15 thereof are the spring hold-down screw in the following module.Workpiece backing plate 9 flexibly connects with movable pin 12.The installation of above-mentioned mold component connects same as the prior art.Its difference is: device discharging pin fixed head in the middle module of upper mould piece, it is connected and composed by upper mounted plate 16 and bottom plate 17 usefulness screws, in bottom plate 17 by T shape head install discharging pin 5 and about decompression thimble 18, left and right decompression thimble 18 and discharging pin 5 penetrate lower module 6 respectively, the length of left and right decompression thimble 18 is greater than the length of discharging pin, in the upper end of discharging pin fixed head 16 energizing spring 2,1 being installed is lock-screw.Decompression thimble 18 among Fig. 4 also can be adorned many.
The course of work of the present utility model: Fig. 3 is a matched moulds state of the present utility model, and on tool member 7 go out flange hole towards pin 8 this moment.Fig. 4 is the utility model discharging state diagram, upper mould piece and workpiece backing plate 9 are up walked during discharging, discharging pin fixed head 16 and 17 walks downward under the effect of spring 2, this moment, left and right decompression thimble 18 and discharging pin 5 also walked downward, when the workpiece backing plate rises to extreme position, can make the discharging pin just in time contact the edge in flange hole by design, the end face of left and right decompression thimble 18 contact simultaneously is the surface of module module 11 down, as shown in Figure 4.When upper mould piece continues to raise, discharging pin 5 draws off the flange hole of tool member 7 from the duct of module 6, meanwhile, the decompression thimble also props up the surface of module 11, the pressure that spring 2 is added to discharging pin fixed head 16 and 17 is born the dividing potential drop effect, thereby reduces the pressure to discharging pin 5, makes 5 pairs of slow dischargings in flange hole of discharging pin, prevent to damage the edge in tool member 7 flange holes, effectively improve yield rate.Fig. 2 illustrates the longitudinal sectional view of being made the slim member 7 of digital camera of flange hole and discharging by the utility model.The utility model improves design for making member 7, but the utility model is not limited to process the slim member 7 of digital camera shown in Figure 2, also is fit to be applied to the discharging behind other thin metal structure manufacture flange hole.
