Abstract
A stainless steel door corner sizing die is characterized in that the stainless steel door corner sizing die comprises a lower die plate, an upper die plate, a wedge, a male die, a side pressing block, a tension spring, a sliding wedge and a female die, the lower portion of the upper die plate is connected with the wedge and the male die, the upper portion of the lower die plate is connected with the side pressing block and the female die, the sliding wedge is arranged between the side pressing block and the female die, and the tension spring is arranged on the side face of the sliding wedge. According to the stainless steel door corner sizing die, a vertical moving die structure is used for completing sizing of side walls, namely all round corners and straight-side portions of door corners, the wedge structure is used for completing sizing of base planes, vertical movement of a press machine is converted into horizontal movement of a clamping mechanism, the purpose that a workpiece is clamped firstly and then sizing is performed on the workpiece is achieved, and it is guaranteed that the base planes of the door corners do not deform. The male die with a variable cross section and the female die with a variable cross section are adopted, and the problem of different deformation of different cross sections of the door corners is solved through different pre-rebound values of different cross sections at the corner of the male die and at the corner of the female die and different cross sections of the straight-side portions. After the stainless steel door corner sizing die is used, the door corners are made to obtain accurate shapes and sizes. The problems that accuracy is very poor, manual adjusting and repairing quality is poor and efficiency is low after the door corners are flanged, sized and cut are solved.
Description
Technical field
The utility model relates to a kind of stainless steel door angle sizing die, and the trimming for the correction after the flanging forming of stainless steel car door angle, belongs to stamping technology field, is applied to subway stainless steel car punching production technical field.
Background technology
The door angle of subway stainless steel car is formation of parts, belongs to the asymmetric flanging forming of open type, and it is complex-shaped, and required precision is high.After adopting symmetrical whole flange moulding, be cut into again 4 parts.Due to the resilience after flange moulding and distortion after cutting, make out of plumb between the sidewall of workpiece and baseplane, baseplane uneven, by manual adjusting, completed in the past always, of poor quality, efficiency is low.
Utility model content
Overproof for overcoming the rear precision of existing stainless steel car door angle shaping, manual adjusting problem of poor quality, inefficient, the utility model provides a kind of stainless steel door angle sizing die, by workpiece part being proofreaied and correct on sizing die, perpendicularity between raising door angle sidewall and baseplane and the flatness of bottom, realization replaces manual adjusting with die reshaping, reaches the object of the form and dimensional precision that improves door angle.
For achieving the above object, the utility model provides a kind of stainless steel door angle sizing die, it is characterized in that: comprise lower bolster, cope match-plate pattern, wedge, punch, side pressing block, extension spring, sliding wedge, die, cope match-plate pattern below connects wedge and punch, lower bolster top connects side pressing block and die, between side pressing block and die, establish a sliding wedge, sliding wedge side arranges extension spring.
The utility model adopts the namely shaping of all fillets and straight portion of sidewall that the mould structure move up and down completes an angle, adopt wedge structure to complete the shaping of baseplane, moving both vertically of forcing press changed into the horizontal movement of clamp mechanism, realize the target of shaping after first clamping work pieces, while guaranteeing shaping, Men Jiao baseplane is indeformable; Take the punch and matrix structure of variable cross-section, adopt differently at the given pre-rebound value of different section of punch and matrix corner and straight line portion, solve the different problem of deflection of the different section at door angle.After the sizing die of application stainless steel door angle, make an angle can reach shape and size more accurately.The precision solving after door angle flanging forming and incision is overproof, a manual adjusting difficult problem of poor quality, inefficient.
Accompanying drawing explanation
Accompanying drawing 1 is stainless steel door of the present utility model angle sizing die structural representation.
Accompanying drawing 2 is A-A cutaway views of accompanying drawing 1.
Accompanying drawing 3 is B-B cutaway views of accompanying drawing 1.
1. lower bolsters in figure, 2. cope match-plate pattern, 3. wedge, 4. punch, 5. side pressing block, 6. extension spring, 7. sliding wedge, 8. die.
The specific embodiment
From accompanying drawing 1, can find out, the sidewall that the mould structure of upper and lower motion completes an angle is the shaping of all fillets and straight portion namely.
From accompanying drawing 2, can find out, cope match-plate pattern 2 belows connect wedge 3, punch 4, and lower bolster 1 top connects side pressing block 5 and die 8, establishes a sliding wedge 7 between side pressing block 5 and die 8, and sliding wedge 7 sides arrange extension spring 6.The wedge structure being comprised of wedge, sliding wedge, changes moving both vertically of forcing press into the horizontal movement of clamp mechanism, completes the shaping of the baseplane at an angle.
From accompanying drawing 3, can find out, blank inclination 45o is placed on die, and while making shaping, convex mould surface contacts blank simultaneously uniformly, completes the shaping of all fillets in an angle and straight flange in one stroke of press.
The course of work of this mould is first the semi-finished product after be shaped cutting to be placed on die 8, and under the effect of press ram, cope match-plate pattern 2 drives wedges 3 descending, promotes sliding wedge 7 baseplane of contact blank that moves right, and is pressed on die 8 and clamps blank.Along with press ram continues descendingly, punch 4 moves downward elder generation and contacts with blank, and under the effect of punch 4 and die 8, blank is out of shape gradually along the shape of punch 4 and die 8, and continuation is descending contacts with die 8 rigidity for punch 4, carries out shaping work.After shaping finishes, press ram drives on punch 4 and wedge 3 and moves, and under the effect of reset tension spring 6, sliding wedge 7 is moved to the left, and recovers origin-location and leaves workpiece, takes out workpiece.
