Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical safety protection, and in particular to a protective device for stamping equipment used in hardware processing. Background Technology
[0002] In the field of metal stamping, during continuous stamping operations of thin sheets and small-sized workpieces, high-speed impact can easily cause scrap or debris to splatter. After leaving the die's working area, this splatter can scratch precision parts on the equipment surface and pose a risk of high-speed impact to operators. To ensure processing safety, a protective structure is usually installed on the front area of the die to intercept splatter and limit its spread.
[0003] Traditional stamping equipment protective devices often employ a combination of rigid frames and fixed baffles, with their structural positions locked during the equipment commissioning phase. These devices consistently occupy the space in front of the die during the stamping process, restricting the operator's movement space when handling workpieces. This is especially problematic when processing small, precision metal parts, requiring operators to repeatedly adjust the angle of their hands to avoid the protective structure, severely reducing work efficiency. Summary of the Invention
[0004] The purpose of this utility model is to solve the shortcomings of traditional stamping equipment protective devices in the prior art, which occupy the space in front of the mold, and to propose a stamping equipment protective device for hardware processing.

[0006] A protective device for stamping equipment used in hardware processing includes a stamping die. Two telescopic support heads are symmetrically arranged on the lower edge of the stamping die. Rotating components are provided on the two telescopic support heads. Half-cover-shaped protective covers are driven and connected to the two rotating components respectively, so that the protective covers are used to form a shielding surface in the vertical stamping direction of the stamping die.
[0007] Preferably, the telescopic support head includes a fixed column, the lower end of which is fixedly installed at the edge of the lower die of the stamping die. A top plate is slidably provided above the fixed column, and a lifting column is fixedly provided on the lower surface of the top plate. A rotating column is rotatably provided in the inner cavity of the fixed column. The lower end of the lifting column is located in the inner cavity of the rotating column. An elastic element is fixedly provided at the bottom of the inner cavity of the rotating column. The upper end of the elastic element is rotatably connected to the bottom of the lifting column. A driving element is provided between the lifting column and the rotating column. The driving element is used to drive the rotating column to rotate when the lifting column moves vertically.
[0008] Preferably, the driving component includes a guide groove formed on the inner wall of the rotating column, a semi-circular slider is fixedly provided on the outer wall of the lower end of the lifting column, the slider is located in the guide groove, and two limiting rods are symmetrically provided on the lower surface of the top plate, the lower ends of the limiting rods are located in the fixed column.

[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] In this invention, the protective device achieves dynamic coordination between the stamping action and the protective structure through the linkage design of the telescopic support head and the rotating component. When the upper die is pressed down, the side wall of the die automatically triggers the displacement of the telescopic support head, driving the rotating component to synchronously unfold the protective cover, forming a planar shield perpendicular to the processing direction at the moment of stamping, accurately intercepting flying debris, and effectively eliminating the blind spots and protection lag problems of traditional fixed protective devices.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0023] In the description of this specification, the references to terms such as "embodiment," "one embodiment," "some implementations," "exemplary," and "one implementation," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or implementation is included in at least one embodiment or implementation of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or implementation. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or implementations.
[0024] Example: This example provides a protective device for stamping equipment used in hardware processing. See [link to example]. Figure 1-4Specifically, the stamping die 1 has two telescopic support heads 11 symmetrically arranged on the lower edge of the stamping die 1. The two telescopic support heads 11 are equipped with rotating components 4. The two rotating components 4 are respectively driven to connect to semi-cover-shaped protective covers 12, so that the protective covers 12 can form a shielding surface in the vertical stamping direction of the stamping die 1. When the upper die descends, it will contact the telescopic support heads 11 on the lower die, causing the telescopic support heads 11 to retract. The telescopic support heads 11 drive the rotating components 4 to rotate by retracting. The rotating components 4 then drive the protective covers 12 to face the front of the stamping die 1, forming a planar shielding barrier perpendicular to the processing direction at the moment of stamping. After the stamping cycle is completed, the protective covers 12 automatically reset, releasing the complete operating space in front of the die, so that the workpiece picking and placing actions are not interfered with by the structure.
[0025] In the specific implementation process, such as Figure 3 and Figure 4 As shown, the telescopic support head 11 includes a fixed column 2. The lower end of the fixed column 2 is fixedly installed at the edge of the lower die of the stamping die 1. A top plate 21 is slidably provided above the fixed column 2. A lifting column 22 is fixedly provided on the lower surface of the top plate 21. A rotating column 23 is rotatably provided in the inner cavity of the fixed column 2. The lower end of the lifting column 22 is located in the inner cavity of the rotating column 23. An elastic element is fixedly provided at the bottom of the inner cavity of the rotating column 23. The upper end of the elastic element is rotatably connected to the bottom of the lifting column 22. A driving element 3 is provided between the lifting column 22 and the rotating column 23. The driving element 3 is used to drive the rotating column 23 to rotate when the lifting column 22 moves vertically. After the upper die contacts the top plate 21, it drives the top plate 21 and the lifting column 22 to descend. The lifting column 22 causes the rotating column 23 to rotate through the driving element 3 and compresses the spring 24. The rotating column 23 then drives the rotating assembly 4 to rotate, converting the force of descent into the power of rotation. The rotating assembly 4 then drives the protective cover 12 to block the front of the stamping die, so that the protective cover 12 moves synchronously with the stamping die 1.
[0026] In the specific implementation process, such as Figure 3 and Figure 4As shown, the driving component 3 includes a guide groove 31 formed on the inner wall of the rotating column 23. A semi-circular slider 32 is fixed on the outer wall of the lower end of the lifting column 22. The slider 32 is located in the guide groove 31. Two limiting rods 33 are symmetrically arranged on the lower surface of the top plate 21. The lower ends of the limiting rods 33 are located in the fixed column 2. The upper half of the guide groove 31 extends in a right-handed equidistant spiral along the axis of the rotating column 23, and the lower half is vertical. When the slider 32 enters the lower half of the guide groove 31 from the upper half, the rotating column 23 rotates... After the slider 32 moves 90 degrees and enters the lower half, the rotating column 23 will no longer rotate. The purpose of setting the guide groove 31 as the upper half and the lower half is to allow the rotating column 23 to rotate a specified distance and then stop rotating after entering the lower half when the upper mold drives the top plate 21 to descend. Since the top plate 21 is restricted by two limit rods 33, the top plate 21 can only move the lifting column 22 up and down. The slider 32 on the lifting column 22 moves in the guide groove 31 to drive the rotating column 23 to rotate.
[0027] In the specific implementation process, such as Figure 2 and Figure 3 As shown, the rotating assembly 4 includes a rotating ring 41 sleeved on the outer wall of the fixed column 2. A straight rod 42 is fixedly mounted on the outer wall of the rotating ring 41, and a round rod 43 is fixedly mounted on the inner wall of the rotating ring 41. One end of the round rod 43 is fixedly connected to the outer wall of the rotating column 23. A telescopic rod 7 is fixedly mounted on the rotating column 23, and one end of the telescopic rod 7 is fixedly connected to the protective cover 12. A rotating groove 6 is opened on one side of the bottom of the fixed column 2, and the round rod 43 passes through the rotating groove 6. When the rotating column 23 rotates, the rotating ring 41 is driven to rotate through the round rod 43. The rotating ring 41 then drives the straight rod 42 to move synchronously, and the straight rod 42 drives the protective cover 12 to move. After the rotating column 23 drives the protective cover 12 to rotate 90 degrees, the ends of the two protective covers 12 are joined together, thus blocking the front of the mold through the protective cover 12.
[0028] In the specific implementation process, such as Figure 2 and Figure 3 As shown, the telescopic rod 7 includes two rectangular rods slidably connected together. One end of one rectangular rod is fixedly connected to the straight rod 42, and the other end of the rectangular rod is fixedly connected to the protective cover 12. The two rectangular rods of the telescopic rod 7 connect the protective cover 12 to the rotating assembly 4 and keep the protective cover 12 away from the central mold. By moving one rectangular rod along the inside of the other rectangular rod, the distance of the protective cover 12 is adjusted to prevent the mold from touching the protective cover 12 during stamping. A protrusion and multiple grooves are provided between the rectangular rods. The position of the rectangular rod is fixed by the protrusion entering the groove.
[0029] In the specific implementation process, such as Figure 3 and Figure 4As shown, the elastic element includes a spring 24 and connecting rings 8 fixedly installed at both ends of the spring 24. A bearing 5 is fixedly provided at the lower end of the lifting column 22. One connecting ring 8 is fixedly connected to the inner ring of the bearing 5, and the other connecting ring 8 is fixedly connected to the bottom of the inner wall of the rotating column 23. Since the rotating column 23 needs to rotate, connecting rings 8 are provided at both ends of the spring 24. The upper connecting ring 8 is connected to the inner ring of the bearing 5, and the outer ring of the bearing 5 is connected to the lifting column 22. When the rotating column 23 drives the spring 24 to rotate, the upper connecting ring 8 rotates along the bottom surface of the lifting column 22 through the bearing 5. When the spring 24 is subjected to downward pressure, it will also rotate with the rotating column 23 to avoid jamming.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
