The guiding device consists of a press (1), an upper die (2), a slide rail (3), a support foot (6), a fixed column (9), a crossbar (10), a support spring (15), a worktable (16), and a centering block (17). The worktable (16) is placed on the press (1), and a groove is opened on the worktable (16). The centering block (17) is placed in the groove, and a support spring (15) is provided between the centering block (17) and the groove. The upper die (2) is placed on the press (1), and the upper die... The upper mold (2) and the workbench (16) are corresponding. The lower part of the upper mold (2) is provided with a slide rail (3). The bottom of the slide rail (3) is provided with multiple support feet (6). The slide rail (3) is formed by combining two semi-circular rods of different radii. The two semi-circular rods are concentric and connected by multiple crossbars (10). The workbench (16) is located between the two semi-circular rods. The semi-circular rods have through grooves that extend from one end to the other end. A fixed column (9) is provided at the center of the slide rail (3). The material changing device consists of a fixed seat (4), a lower mold (5), a connecting rod (7), a throttle (8), and a positioning column. (11) The assembly consists of a fixed sleeve (12), a sliding ring (13), rollers (14), a sliding seat (18), and a positioning hole (19). The throttle (8) is placed on the fixed post (9) through the fixed sleeve (12). Two connecting rods (7) are placed on the fixed sleeve (12) and are perpendicular to each other. The fixed seat (4) is placed on the connecting rods (7) and is connected by an arc-shaped rod. The fixed seat (4) has a circular frame structure. Two sets of rollers (14) are provided at the bottom of the fixed seat (4). The two sets of rollers (14) are placed in the through grooves of the two semi-circular rods. A limit groove is opened on the inner wall of the fixed seat (4). The sliding seat (18) is placed inside the fixed seat (4). A sliding ring (13) is placed on the outer wall of the sliding seat (18). The sliding ring (13) is engaged in the limiting groove. A support spring (15) is provided between the sliding ring (13) and the limiting groove. A centering groove is opened at the bottom of the sliding seat (18). The centering groove and the centering block (17) are corresponding. Multiple positioning pins (11) are placed on the sliding seat (18) at equal angles. The lower mold (5) is placed on the sliding seat (18). Multiple limiting holes are opened at equal angles on the lower mold (5). The limiting holes and the positioning pins (11) are engaged in the corresponding way. A protective sleeve is placed on the throttle (8).

[0020] In use, the sheet metal to be stamped is placed on the lower mold (5) of one of the fixed seats (4). By rotating the handle (8), the fixed seat (4) with the sheet metal is moved to the lower mold (2) of the press (1). The centering block (17) on the worktable (16) is engaged with the centering groove of the sliding seat (18). The press (1) is started to press down the upper mold (2) to stamp the kitchenware. During the stamping of the sheet metal, the operator can place the second set of sheet metal on the lower mold (5) of another fixed seat (4). After the first set of kitchenware is stamped, the handle (8) is rotated to move the fixed seat (4) to the lower mold (5) of the press (16). The fixed seat (4) of the stamped thin plate is moved away from the worktable (16), so that another fixed seat (4) of the thin plate is moved to the worktable (16) for the second set of kitchen utensils stamping. During the second set of kitchen utensils stamping, the first set of kitchen utensils is removed and the third set of thin plates to be stamped is placed. This process is repeated. The material is picked up and put down during the stamping time, which saves time and improves work efficiency. Moreover, it does not require the staff to put their hands under the press (1) to pick up and put down the material, which has a low risk factor. At the same time, it provides more time for the staff to put down the material, which makes it easier to arrange the workpieces neatly.

[0021] The corresponding engagement design of the limiting hole and the positioning post (11) enables the upper mold (2) to be limited by the limiting hole and the positioning post, so as to avoid the upper mold (2) from shifting due to inertial force during the sliding of the fixed seat (4) and affecting the stamping effect.

[0022] The design of the support spring (15) is such that when the press (1) drives the upper mold (2) to press down, the thin plate is placed on the lower mold (5) and subjected to the impact of the upper mold (2). The support spring (15) can support and buffer the impact force through its own elastic strain, so as to avoid damage to the sliding seat (18) caused by the impact force.

[0023] The design of the protective sleeve on the throttle (8) can protect the worker's hands when the worker rotates the fixed seat (4) through the throttle (8), and prevent the worker's hands from being damaged by friction.

[0024] The design of connecting the two fixed seats (4) with an arc rod can enhance the tightness of the connection between the two fixed seats (4), and form a fan-shaped structure with the connecting rod (7) to provide stable support for the fixed seats (4);

[0025] The design of the centering groove and the centering block (17) is such that the fixed seat (4) can be engaged on the worktable (16), which enhances the stability of the fixed seat (4) and avoids the impact of the sliding displacement of the fixed seat (4) on the stamping of the kitchenware workpiece.

[0026] The design of the fixed seat (4), the handle (8) and the slide rail (3) is such that when in use, the handle (8) is turned so that the fixed seat (4) moves on the slide rail (3) and the fixed seat (4) with the thin plate is moved to the upper mold (2) of the press (1). The centering block (17) on the worktable (16) is engaged in the centering groove of the slide seat (18). The press (1) is started so that the upper mold (2) is pressed down to stamp the kitchenware. During the stamping of the thin plate, the operator can place the second set of thin plates on the lower mold (5) of another fixed seat (4). After the first set of kitchenware is stamped, the fixed seat (4) with the stamped thin plate is moved away from the worktable (16) by rotating the handle (8) so that the other fixed seat (4) with the thin plate is moved to the worktable (16) for the second set of kitchenware to be stamped. This cycle can be repeated to take out and put out materials during the stamping time, further saving time and improving work efficiency.

[0027] The goal is to enable material changing during the stamping time period, saving time and avoiding the danger of personnel's hands going under the press (1) during material changing.
