The specific embodiment
Relevant detailed description of the present utility model and technology contents, be described as follows cooperation accompanying drawing, yet appended accompanying drawing is only as illustrative purposes, not for limiting to the utility model.
Consult Fig. 3, preferred embodiment of the present utility model provides a kind of shaping dies, and this shaping dies includes the first die 110, the second die 120, staking punch 210, slide block 220 and push rod 230.
The first die 110 is metal rectangle block, its have the first machined surface 111 and with vertical the first junction 112 being connected of the first machined surface 111.On the first die 110, offer the groove 101 of a wide and flat shape, the flat horizontal surface of groove 101 is completely open and on the first machined surface 111, is formed with the first opening 113; A side of groove 101 is completely open and on the first junction 112, is formed with the first port 114, the first openings 113 and the first port 114 is interconnected.On the first junction 112, the both sides of the first port 114 are provided with a pair of the first rail structure 115, and each first rail structure 115 is preferably respectively dovetail groove (dovetail groove), but the utility model does not limit its form.
The second die 120 is metal rectangle block, its have the second machined surface 121 and with vertical the second junction 122 being connected of the second machined surface 121.On the second die 120, offer barb groove 102, barb groove 102 is formed with the second opening 123 on the second machined surface 121, so that barb groove 102 is part on the second machined surface 121, opens and part crested; Barb groove 102 forms the second port 124, the second openings 123 on the second junction 122 and the second port 124 is interconnected.On the second junction 122, the both sides of the second port 124 are provided with a pair of second rail structure 125 of corresponding each first rail structure 115, and each second rail structure 125 is preferably respectively the dovetail (dovetail joint) that coordinates its first corresponding rail structure 115.
The first die 110 and the second die 120 are connected with group and form die assembly 100, when group connects, by the first rail structure 115 corresponding to each the second rail structure 125 joggles, locate.After 120 groups of the first die 110 and the second dies connect, the first junction 112 is attached at the second junction 122, first port 114 docking the second ports 124 and groove 101 and barb groove 102 are interconnected form forming tank 131, the first machined surface 111 connects the second machined surfaces 121 and on die assembly 100, forms that binder surface 132, the first openings 113 are communicated with the second openings 123 and form binder mouth 133 on binder surface 132 at die assembly 100.
Staking punch 210 is metal block, and it is to position configuration that should the first opening 113.On staking punch 210, be formed with guiding face 211, guiding face 211 is parallel to the forward of the first opening 113 and the forward of guiding face 211 along the forward configuration of the first port 114.The part outline of staking punch 210 matches with the first opening 113.
Slide block 220 and staking punch 210 row arrangement and form punch assemblies 200, the position of the corresponding binder mouth 133 in position of punch assemblies 200, slide block 220 can for example, be drawn close and can with respect to staking punch 210, move along the forward of the first opening 113 to staking punch 210 in the mode that pushes away or draw by elastic parts (spring).When staking punch 210 and slide block 220 are drawn close, the interior match profiles of the outline of punch assemblies 200 and binder mouth 133 is closed.Domatic 221 and the flange 222 that on slide block 220, are formed with opposing configuration, the profile of flange 222 is corresponding with the interior profile of barb groove 102, and the interior match profiles of the part outline of flange 222 and the second opening 123 is closed.
Push rod 230 is disposed between this staking punch 210 and slide block 220, and the side 231 of push rod 230 is resisted against on the guiding face 211 of staking punch and makes the push rod 230 can be along guiding face 211 slippages.The lateral margin of push rod 230 ends is formed with lead angle 232, lead angle 232 and this opposing configuration in side 231.
Consult Fig. 4 and Fig. 5, shaping dies of the present utility model is used for working sheet 310 to form a housing 320 with barbed edge.The corresponding binder mouth 133 of sheet material 310 arranges, and staking punch 210 is drawn close mutually with slide block 220, and punch assemblies 200 moves and sheet material 310 is pressed into forming tank 131 so that sheet material 310 punching presses are formed to housing 320 by binder mouth 133 to binder surface 132.
Consult Fig. 5, punch assemblies 200 pours after forming tank 131, push rod 230 continues along guiding face 211 towards 100 slippages of die assembly, the lead angle 232 pushing and pressing slide blocks 220 of push rod 230 domatic 221 and slide block 220 is pushed away to staking punch 210, and the flange of slide block 220 222 is pushed to barb groove 102, and a lateral edges of housing 320 is pressed into barb groove 102 to flange 222 and that this edge is formed is barb-like.
Push rod 230 is shunk back and is made slide block 220 draw close and be beneficial to punch assemblies 200 and exit forming tank 131 to staking punch 210.Then along the configuration direction of the first rail structure 115 and the second rail structure 125, the first die 110 is separated with the relative slippage of the second die 120, and then housing 320 can be deviate from die assembly 100.As shown in Figure 6, die parting line 321 on housing 320 is to form along the interface of the first die 110 and the second die 120 (the first junction 112 or the second junction 122), therefore die parting line 321 only small part be positioned at the edge of housing 320, be therefore easy to follow-up die parting line and remove processing.
The above, be only illustrating of preferred embodiment of the present utility model, and not in order to limit to protection domain of the present utility model, other any equivalent transformation all should belong to the application's claim scope.
