In order to more clearly describe the scheme of the application, the prior art is further described herein, and as in the background art, when the bearing baffle plate is blanked, the blanking operation of the bearing baffle plate can be completed by carrying out reciprocating punching on the material plate for 5 times. Due to the multiple blanking steps, during the blanking operation of the bearing baffle plate, the deviation of the guide hole 311, the middle hole 321 and the screw hole 323 is easy to occur, the die repairing operation time of the subsequent bearing baffle plate is increased, and the stamping efficiency and the blanking quality of the bearing baffle plate after blanking are difficult to ensure.
In one embodiment, the material web 3 is first placed on the bearing surface 11 of the lower die 1. The punching machine is started, and drives the upper die 2 to move downwards, and the first punching area 21 of the upper die 2 descends to the first pressure receiving area 12 of the punching lower die 1. Wherein, the guide punching column 211 impacts the material belt 3 to the guide punching hole 121, and a guide hole 311 is formed on the material belt 3; when the upper die 2 extrudes the material belt 3 downwards, the step convex hull column 122 of the lower die 1 has upward punching force on the material belt 3, namely, the step convex hull column 122 punches the material belt 3 upwards, and the step convex hull 312 is formed on the material belt 3. When the step convex hull column 122 presses the step convex hull 312 on the material belt 3 upwards, the step convex hull 312 is abutted with the second step column 212 of the upper die 2, and the second step column 212 impacts the step convex hull 312 downwards so that a second concave part 313 is formed in the step convex hull 312, and therefore subsequent punching of screw holes 323 is conveniently performed on the material belt 3. The punch then drives the upper die 2 up to disengage from the pressing of the blank. The plate is moved horizontally to the right, and the position where the plate is blanked by the first punching section 21 is moved to the second compression section 13 of the lower die 1 for the next blanking. Finally, the press drives the upper die 2 downward, and the second punching area 22 of the upper die 2 descends to the second compression area 13 of the lower die 1. The contour stamping columns 221 of the upper die 2 extrude the blank plate and blanking forms the baffle contour 322. When the contour punching column 221 descends to press the material plate, the middle position of the material plate is supported by the middle bearing column 131, and when the baffle contour 322 descends under the action of the contour punching column 221, the material belt 3 at the middle position of the baffle contour 322 is supported by the middle bearing column 131 and cannot move downwards, i.e. the material belt 3 at the middle position of the baffle contour 322 has a position change moving upwards relative to the baffle contour 322, and then a middle hole 321 is formed in the middle of the baffle contour 322.
It should be noted that, when the upper die 2 is driven by the punching machine to descend, the first punching area 21 and the second punching area 22 move down synchronously, that is, during normal operation, the punching die of the bearing baffle plate can perform punching operation on 2 bearing baffle plates at the same time, so as to ensure punching efficiency on the bearing baffle plates.
Preferably, the step convex hull column 122 has a first column 1221 and a second column 1222 which are integrally formed, the diameter of the second column 1222 is larger than that of the first column 1221, and a rounded corner 1223 is provided at the junction of the first column 1221 and the second column 1222, so as to prevent the fracture phenomenon between the first column 1221 and the second column 1222.
In one embodiment, rounded corners 1223 are provided between the first and second columns 1221 and 1222 to help strengthen the connection between the first and second columns 1221 and 1222 while avoiding stress concentrations during stamping of the blank by the stepped convex hull column 122. Second, the stepped convex hull 312 formed has good mechanical properties.
Preferably, second stepped post 212 has a main post 2121 and a stamped protrusion 2122 at the bottom of main post 2121, stamped protrusion 2122 having a diameter smaller than the diameter of stepped convex hull 312, and stamped protrusion 2122 downwardly presses stepped convex hull 312 to form second recess 313.
Preferably, the contour stamping columns 221 are recessed inward with accommodating grooves, and the accommodating grooves can accommodate the step convex hulls 312, so that the step convex hulls 312 are prevented from being extruded when the blanking operation is performed on the material strips 3.
Preferably, the depth of the middle groove is larger than the thickness of the material belt 3, so that the surplus material generated after the middle hole 321 is punched can be separated from the baffle outline 322, namely, the surplus material at the middle hole 321 is separated from the baffle outline 322.
Preferably, the upper die 2 and the lower die 1 are both provided with mounting seats 4, two sides of each mounting seat 4 are provided with U-shaped steps 41, the inner sides of the U-shaped steps 41 are provided with U-shaped holes 42, fastening bolts penetrate through the U-shaped holes 42 and are abutted to the U-shaped steps 41, screw portions of the fastening bolts can slide along the U-shaped holes 42, so that certain moving gaps are reserved when the upper die 2 and the lower die 1 are mounted, and the positions of the upper die 2 and the lower die 1 are conveniently adjusted to adjust the mutual alignment of the upper die 2 and the lower die 1.
When the stamping die for the bearing baffle plate is adopted, the first compression area 12 and the second compression area 13 are arranged on the lower die 1, the first stamping area 21 and the second stamping area 22 are correspondingly arranged on the upper die 2, and the stamping for the bearing baffle plate can be realized through only two stamping steps, namely, the first step, the stamping guide hole 311 and the stamping step convex hull 312; and step two, punching the middle hole 321, the screw hole 323 and the baffle contour 322 to perform blanking. The blanking step is shortened, the flatness of the bearing baffle plate and the perpendicularity of the screw tooth holes 323 which are subjected to blanking are guaranteed conveniently, the damage rate of the bearing baffle plate in the stamping process is reduced, and the bearing baffle plate can be blanked by two stamping beats, so that the efficiency is high.
The foregoing is merely exemplary of the present application and is not intended to limit the present application. Various modifications and changes may be made to the present application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc. which are within the spirit and principles of the present application are intended to be included within the scope of the claims of the present application.
