[0034] Example 1

[0035] like Figs. 1 to 3 As shown, this embodiment provides a stamping and deburring die for an induction cooker mounting plate. The induction cooker mounting plate 1 is provided with mounting holes 11, and the die includes an upper template, a lower template 2, and a limiting component.

[0036] The lower template 2 is provided with a positioning groove 21 that matches the shape of the induction cooker mounting plate 1. The positioning groove 21 includes a rectangular part 22 and an arc part 23 connected to each other. The positioning groove 21 is provided with a deburring punch 24 that corresponds to the position of the mounting hole 11 and matches its shape.

[0037] A limiting groove 25 is provided at the edge of the positioning groove 21. The limiting groove 25 is distributed around the positioning groove 21. The limiting member is installed in the limiting groove 25, and the side of the limiting member close to the positioning groove 21 is tangent to the edge of the positioning groove 21.

[0038] Working principle: The induction cooker mounting plate 1 is placed in the positioning groove 21. The limiting parts set around the positioning groove 21 limit the plane position of the induction cooker mounting plate 1 in the positioning groove, so that the mounting hole 11 on the induction cooker mounting plate 1 is aligned with the corresponding deburring punch 24 in the positioning groove 21. Then, the workpiece is pressed down by the upper template, and the deburring punch 24 enters into the mounting hole 11 to complete the deburring process of the mounting hole 11.

[0039] The lower die base 3 is provided with a positioning groove 21 and a limiting piece, and the electromagnetic oven mounting plate 1 is positioned and planarly limited by the positioning groove 21 and the limiting piece, so that the mounting hole 11 can be accurately deburred, and the debris generated by the deburring of the mounting hole 11 is pushed to the upper surface of the workpiece by the deburring punch 24, thereby avoiding the damage of the workpiece caused by the debris under the workpiece and the damage of the product quality caused by the scratches on the workpiece.

[0040] In a preferred embodiment, the deburring punch 24 comprises a deburring section and a circular truncated cone section connected with each other.

[0041] The deburring section is vertically fixed at the bottom of the positioning groove 21, and the circular truncated cone section is located at the end of the deburring section away from the lower die base, and the circular truncated cone section is in clearance fit with the mounting hole 11, and the deburring section is in transition fit with the mounting hole 11.

[0042] When the electromagnetic oven mounting plate 1 is placed in the positioning groove 21, the circular truncated cone section at the upper end of the deburring punch 24 can be initially located in the mounting hole 11, and the electromagnetic oven mounting plate 1 and the mounting hole are planarly limited and positioned by the limiting piece at the edge of the positioning groove 21, thereby improving the positioning accuracy of the mounting hole 11 and the deburring quality of the mounting hole 11 by the deburring section of the deburring punch 24.

[0043] In a preferred embodiment, the limiting piece is a cylindrical rod structure.

[0044] The cylindrical rod structure is used to limit the periphery of the electromagnetic oven mounting plate 1, and the limiting piece is in line contact with the electromagnetic oven mounting plate 1, which can reduce the over-limiting of the electromagnetic oven mounting plate 1 caused by the machining precision of the edge of the electromagnetic oven mounting plate 1 and the deformation of the electromagnetic oven mounting plate 1, thereby ensuring the quality of the electromagnetic oven mounting plate 1, compared with the existing rectangular structure of the clamping block.

[0045] Optionally, the bottom of the positioning groove 21 is provided with a return spring, one end of the return spring is fixed on the lower die base, and the other end is in movable contact with the electromagnetic oven mounting plate 1.

[0046] Further, the distance between the end face of the end of the return spring away from the lower die base 3 and the bottom of the positioning groove 21 is less than the distance between the end face of the end of the deburring punch 24 away from the lower die base and the bottom of the positioning groove 21.

[0047] The number of return springs is multiple, and each return spring is uniformly distributed at the bottom of the positioning groove 21.

[0048] By setting reset spring at the bottom of positioning groove 21, cooperate with the round table section set at the upper end of deburring punch 24, when the upper die plate is not closed, the electromagnetic stove mounting plate 1 is initially clamped on the round table section, the reset spring contacts the lower end surface of the electromagnetic stove mounting plate 1, but is not compressed, avoiding interference to the positioning of the electromagnetic stove mounting plate 1, ensuring the accuracy of the electromagnetic stove mounting plate 1. After the mold is closed and the deburring of the electromagnetic stove mounting plate 1 is completed, the reset spring is compressed and reset, pushing the electromagnetic stove mounting plate 1 out of the deburring punch 24, facilitating the removal of the electromagnetic stove mounting plate 1 and improving work efficiency.

[0049] Specifically, the mounting hole 11 includes a circular hole and a square hole, the deburring punch 24 includes a square column punch and a cylindrical punch, the square column punch cooperates with the square hole, and the cylindrical punch cooperates with the circular hole.

[0050] Further, the square column punch is symmetrically distributed at both ends of the rectangular part 22, and the cylindrical punch is in a triangular structure and located inside the circle where the arc part 23 is located.

[0051] Specifically, the mold further includes a guide column, an upper die seat and a lower die seat, the guide column is fixed on the lower die seat, the upper die seat is provided with a guide hole, and the guide column is movably inserted into the guide hole. The upper die seat and the lower die seat are provided with a limiting column. The moving direction and relative position between the upper die seat and the lower die seat are ensured, and the deburring accuracy and reliability of the mounting plate are improved.

[0052] The above describes the preferred embodiments of the present application in detail. It should be understood that those skilled in the art can make many modifications and changes without creative labor according to the concept of the present application. Therefore, any technical solution obtained by logical analysis, reasoning or limited experiment on the basis of the existing technology according to the concept of the present application shall be within the protection scope defined by the claims.
