The left and right ends of the base 3-1 are symmetrically provided with a left supporting seat 3-2 and a right supporting seat 3-3; the left supporting seat 3-2 and the right supporting seat 3-3 are both of cuboid structures; the distance from the inner surface of the left supporting seat 3-2 to the inner surface of the right supporting seat 3-3 is equal to the width of the punch 5; the inner surfaces of the left supporting seat 3-2 and the right supporting seat 3-3 form a guide rail surface for lifting the punch 5; a left baffle 3-5 is fixedly arranged behind the left supporting seat 3-2, and a right baffle 3-6 is fixedly arranged behind the right supporting seat 3-3; a front supporting seat 3-4 is arranged at a position between the left supporting seat 3-2 and the right supporting seat 3-3 and close to the front; a rectangular block 3-7 is detachably arranged in the center of the front supporting seat 3-4; the rectangular block 3-7 is provided with a rectangular hole 3-7-1 matched with the width and the thickness of the copper bar to be blanked;
the stripper plate 2 is fixedly arranged on the supporting guide rail component 3; the stripper plate 2 is provided with a stripper plate hole 2-1 through which the punch 5 passes;
an upper die holder 1 is arranged above the stripper plate 2.
The four corners of the upper die holder 1 and the stripper plate 2 are respectively connected through a spring limiting component A; in practical application, the spring limiting assembly A comprises a heavy-duty rectangular spiral spring A1 and an equal-height sleeve A2; the bottom end of the equal-height sleeve A2 is fixed with one corner of the stripper plate 2; the top end of the equal-height sleeve A2 extends to the upper part of the upper die holder 1 after penetrating through a through hole at one corner of the upper die holder 1, and a cover cap is arranged at the top end of the equal-height sleeve A2; the outer surface of the equal-height sleeve A2 is sleeved with a heavy-load rectangular coil spring A1, so that the heavy-load rectangular coil spring A1 is positioned between the stripper plate 2 and the upper die base 1. The purpose of adopting this kind of design is: since the equal-height sleeve a2 is fixed to the stripper plate 2, the position of the equal-height sleeve a2 is fixed. However, the upper die holder 1 can slide downwards along the equal-height sleeve a2 under the action of external force, and meanwhile, the heavy-duty rectangular coil spring a1 is compressed, so that the effect that the upper die holder 1 moves downwards relative to the stripper plate 2 is achieved. And when the external force is released, the upper die holder 1 slides upwards to reset under the action of the elastic force of the heavy-duty rectangular spiral spring A1. By
The punch 5 is rectangular, and the top end of the punch 5 is fixed with the bottom surface of the upper die base 1; therefore, when the upper die holder 1 moves downwards under the action of external force, the punch 5 is driven to move synchronously. The bottom end of the punch 5 penetrates through the stripper plate hole 2-1 and extends to a position between the left support seat 3-2 and the right support seat 3-3; and the left side surface and the right side surface of the punch 5 are respectively in sliding contact with the inner surface of the left supporting seat 3-2 and the inner surface of the right supporting seat 3-3, so that the verticality of the downward movement of the punch 5 is ensured.
A rectangular knife hole 5-1 matched with the width and the thickness of the copper bar to be blanked is formed below the punch 5; the rectangular knife hole 5-1 and the rectangular hole 3-7-1 are coaxial and equal in height.
The utility model provides a copper bar unloading mould, its using-way is:
(1) at the beginning, no external force is applied to the upper die base 1, and at the moment, the rectangular knife hole 5-1 of the punch 5 and the rectangular hole 3-7-1 of the supporting guide rail assembly 3 are coaxially equal in height.
Then, on one hand, the front end of the whole copper bar sequentially penetrates through the rectangular hole 3-7-1 and the rectangular knife hole 5-1 and extends to the back of the rectangular knife hole 5-1; and the front end of the copper bar is continuously and automatically fed; on the other hand, make the mould stroke from top to bottom move, namely: the upper die base 1 moves downwards under the action of external force, so that the punch 5 moves downwards, and the punch 5 plays a role of a cutter as the periphery of the rectangular cutter hole 5-1 of the punch 5 is of a cutter structure, so that the copper bar is cut off by the rectangular cutter hole 5-1 of the punch 5. At this time, the cut copper bar is separated from the punch 5. The front end of the remaining copper bar is supported by the rectangular hole 3-7-1 of the rectangular block 3-7 and cannot be separated from the rectangular block 3-7;
(2) when a certain section of copper bar is cut off, external force is released, the stroke of the die is from bottom to top, the heavy-duty rectangular spiral spring releases pressure, the equal-height sleeve plays a limiting role, and the upper die base 1 and the punch 5 reset upwards;
(3) and then, the front end of the residual copper bar moves forwards for a required length. And applying external force to enable the upper die holder 1 and the punch 5 to move downwards to cut off the copper bar, and repeating the steps continuously to realize continuous downward cutting of the copper bar.
In practical application, external force can be applied to the upper die holder 1 through the press machine, so that the die can work in a reciprocating mode along with the stroke of the press machine, and continuous blanking of the copper bar is achieved.
Therefore, the utility model provides a copper bar unloading mould has following advantage:
the blanking processing efficiency of the copper bar can be improved, and the production cost is greatly reduced; in addition, the die is continuously blanked, so that the consistency of products is ensured, and the processing precision of the products is improved.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations should also be viewed as the protection scope of the present invention.
