[0021] The above and other technical features and advantages of the present invention are described in more detail below in conjunction with the accompanying drawings.

[0022] This embodiment provides a technical solution: a stamping device used for processing safe and high-performance luggage locks, such as Figure 1 As shown, the present invention comprises: a stamping box 1, a mounting plate 3 and a stamping block 6.

[0023] In the specific implementation, such as Figure 4-Figure 7 As shown, the stamping box 1 has a stamping groove 2 at the bottom.

[0024] In the specific implementation, such as Figure 1 As shown, the mounting plate 3 is arranged below the stamping box 1, hydraulic cylinders 4 are installed on both sides of the stamping box 1, connecting plates 5 are installed on both sides of the mounting plate 3, and the connecting plates 5 are installed at the output end of the hydraulic cylinder 4. The hydraulic cylinder 4 can drive the connecting plates 5 and the mounting plate 3 to move up and down.

[0025] In the specific implementation, such as Figure 1-Figure 3 As shown, the punching block 6 is fixedly mounted on the top of the mounting plate 3 and is located below the punching slot 2. Driven by the hydraulic cylinder 4, the mounting plate 3 can be controlled to move up and down, and the punching block 6 can also be controlled to move up and down. When the punching block 6 moves upward into the punching slot 2, the metal plate placed above the punching block 6 can be punched, thereby realizing punching forming. Two punching sheets 7 are provided on the top of the punching block 6 in mirror contact. The top area of ​​the two punching sheets 7 is the same as the cross-sectional area of ​​the punching block 6. Therefore, in this embodiment, the punching operation on the metal plate is completed by the two punching sheets 7 above the punching block 6.

[0026] In the specific implementation, such as Figure 2As shown, mounting support rods 8 are installed on the front and rear sides of both ends of the stamping block 6, and a connecting block 9 is installed at the bottom of the stamping sheet 7. The connecting block 9 is rotatably installed between the front and rear mounting support rods 8 through an axial rod. Since the connecting block 9 at the bottom of the stamping sheet 7 is rotatably connected to the mounting support rod 8 through an axial rod, the stamping sheet 7 can rotate without the influence of other external forces.

[0027] In the specific implementation, such as Figure 2 and Figure 3 As shown, a control component 10 for controlling the position of the stamping sheet 7 is provided in the stamping block 6, and the control component 10 includes a control cylinder 1001, a brake plate 1002 and two linkage plates 1003. A receiving groove is provided at the center of the stamping block 6, and expansion grooves are provided on both sides of the inner wall of the receiving groove. The control cylinder 1001 is installed on the inner wall of the receiving groove, and the brake plate 1002 is provided in the expansion groove and installed at the output end of the control cylinder 1001. The brake plate 1002 can be controlled to move up and down by the control cylinder 1001. Lower connecting clamps 11 are installed on both sides of the top of the brake plate 1002, and an upper connecting clamp 12 is installed at the bottom of the stamping sheet 7. Both ends of the linkage plate 1003 are connected by shafts. They are rotatably installed between the upper connecting clamp block 12 and the lower connecting clamp block 11 respectively. Since the brake plate 1002, the linkage plate 1003 and the connecting block 9 at the bottom of the stamping sheet 7 are arranged through three rotating connection structures, the stamping sheet 7 can be guaranteed to be stable and still when the control cylinder 1001 does not move. When the control cylinder 1001 drives the brake plate 1002 to move, the stamping sheet 7 can be controlled to move through the linkage plate 1003. The stamping sheet 7, the linkage plate 1003 and the brake plate 1002 form a Z shape. The linkage plate 1003 is tilted, so that when the brake plate 1002 moves downward, the linkage plate 1003 can have space to move downward. The initial state of the control cylinder 1001 is a fully extended state. Figure 2 and Figure 3 As shown, at this time, the two upper stamping plates 7 are arranged horizontally, and when the control cylinder 1001 moves downward to drive the brake plate 1002 to move downward, it can drive the lower end of the linkage plate 1003 to move downward, so the inclination angle of the linkage plate 1003 becomes smaller and drives the side in contact with the stamping plate 7 to move downward, and at the same time, the two ends of the linkage plate 1003 can rotate adaptively. Since the connecting block 9 at the bottom of the other side of the stamping plate 7 is rotatably connected to the mounting support rod 8 through the shaft rod, the stamping plate 7 rotates with the connecting axis, so that the shape changes of the two stamping plates 7 can be adjusted and controlled.

[0028] In the specific implementation, such as Figure 3As shown, both sides of the stamping block 6 are provided with corner stamping components 13 for changing the shape of both sides of the luggage lock shell, and the corner stamping components 13 include a stamping arc piece 1301, a push rod 1302, a square push piece 1303 and a limit spring 1304. Both sides of the stamping block 6 are provided with a placement cavity 14, and the placement cavity 14 and the upper surface of the stamping block 6 are provided with a through hole 15. The stamping arc piece 1301 is arranged between the stamping block 6 and the stamping piece 7, and the luggage lock can be adjusted by the stamping arc piece 1301. The two sides of the shell are squeezed to achieve the purpose of changing the shape, the square push piece 1303 is clamped in the placement cavity 14, the push rod 1302 is installed between the stamping arc piece 1301 and the square push piece 1303 and is clamped in the through hole 15, the limit spring 1304 is installed between the square push piece 1303 and the inner wall of the placement cavity 14, and the position of the square push piece 1303 can be limited by the limit spring 1304. A U-shaped groove 16 is opened between the bottom of the accommodating cavity and the top outer wall of the expansion groove, and the brake plate A pressure rod 17 is installed on both sides of the bottom of 1002, and the bottom of the pressure rod 17 is clamped at the end of the U-shaped groove 16. Since the pressure rod 17 is installed at the bottom of the brake plate 1002, it can move with the movement of the brake plate 1002. When the position of the stamping sheet 7 is changed, the pressure rod 17 can also move downward during the downward movement of the brake plate 1002. Therefore, the pressure rod 17 can be continuously moved to one side of the U-shaped groove 16 to increase the pressure inside the U-shaped groove 16, so that the U-shaped groove 16 can be pressed under the pressure. The other side enters the placement cavity 14, and under the action of pressure, it can push the square push piece 1303 to squeeze the limit spring 1304 and move upward, so that the stamping arc piece 1301 can be pushed upward by the push rod 1302, so that the stamping arc piece 1301 can change the position of the stamping piece 7 and the stamping arc piece 1301 at the same time, and finally the stamping arc piece 1301 can be moved to the top of the stamping piece 7, and the stamping arc piece 1301 can be used to perform secondary stamping on both sides of the luggage lock shell to change the shape of both sides of the luggage lock shell.

[0029] Furthermore, the U-shaped groove 16 is filled with hydraulic oil 18, and the hydraulic oil 18 can greatly improve the conduction effect, thereby ensuring that the stamped arc piece 1301 can be moved to the correct position.

[0030] Furthermore, a rubber sealing head 19 is installed at the bottom of the pressure rod 17, and the rubber sealing head 19 is clamped in the U-shaped groove 16. The rubber sealing head 19 can ensure good sealing performance, thereby preventing leakage.

[0031] Furthermore, expansion grooves 20 are opened on both sides of the top of the inner wall of the stamping groove 2. The overlap between the expansion groove 20 and the stamping groove 2 is an arc edge, which corresponds to the stamping arc piece 1301. The stamping arc piece 1301 pushes the luggage lock shell component, and the top of the luggage lock shell component can finally fit the arc edge to achieve the deformation requirement.

[0032] Furthermore, arc-shaped bottom edges 21 are provided at the bottoms of both sides of the punching sheet 7, thereby ensuring that the punching sheet 7 can accurately complete the rotation and change operation.

[0033] Furthermore, a plurality of legs 22 are installed at the bottom of the stamping box 1 , and a guide hole 23 is opened on the mounting plate 3 , and the legs 22 are clamped in the guide hole 23 , so that the stability of the stamping box 1 during use can be improved by the legs 22 .

[0034] In the specific implementation, such as Figure 4-Figure 7 As shown, a receiving groove 24 is provided on the top of the stamping box 1, and an auxiliary positioning component 25 for positioning the luggage lock shell is provided in the receiving groove 24. The luggage lock shell formed by primary stamping can be fixed on the inner wall above the stamping groove 2 through the auxiliary positioning component 25, so as to facilitate the subsequent position adjustment of the stamping sheet 7 and the position adjustment of the arc sheet. The auxiliary positioning component 25 includes a fixing plate 25013, an electric telescopic rod 2502 and a sealing sheet 2503. The fixing plate 25013 is fixedly installed on the top of the stamping box 1, and the electric telescopic rod 2502 is arranged in the receiving groove 2 4 and the electric telescopic rod 2502 is fixedly installed under the fixing plate 25013, the sealing sheet 2503 is clamped in the accommodating groove 24 and the sealing sheet 2503 is installed at the output end of the electric telescopic rod 2502, the sealing sheet 2503 can be driven to move up and down by the electric telescopic rod 2502, a plurality of positioning suction holes 26 are opened between the accommodating groove 24 and the stamping groove 2, when the electric telescopic rod 2502 drives the sealing sheet 2503 to move upward, negative pressure can be generated between the sealing sheet 2503 and the accommodating groove 24, and the luggage lock shell can be adsorbed and fixed through the positioning suction holes 26.

[0035] When the present invention is in use, the internal structure of the punching block 6 can be used to perform stamping and forming operations on the luggage lock shell parts and the arc edge forming operations on both sides of the luggage lock shell parts. One device can complete two processing steps, thereby improving production efficiency and greatly reducing cost investment. During processing, the metal plate is placed between the punching block 6 and the punching groove 2, and the hydraulic cylinder 4 is controlled to retract, so that the hydraulic cylinder 4 can drive the connecting block 9 and the mounting plate 3 to move upward, thereby driving the punching block 6 to move upward, and the two punching sheets 7 above the punching block 6 can contact the metal plate, and the punching operation can be completed when passing through the bottom notch of the punching groove 2. At this time, the preliminary punching is completed, and the punching block 6 and the two punching sheets 7 on the top can push the punched luggage lock shell parts to the top of the inner wall of the punching groove 2. At this time, the position of the luggage lock shell parts is as shown in FIG. Figure 4As shown, the electric telescopic rod 2502 is then controlled to retract, and the electric telescopic rod 2502 can drive the sealing sheet 2503 to move slightly upward, so that negative pressure can be generated between the sealing sheet 2503 and the accommodating groove 24, and the luggage lock shell can be adsorbed and fixed under the action of negative pressure through the positioning suction hole 26. Then, before the secondary stamping operation, the position adjustment operation of the stamping sheet 7 and the stamping arc sheet 1301 is required. When adjusting the position, the hydraulic cylinder 4 is first controlled to move slightly downward, so that the stamping block 6 can move downward and no longer contact the luggage lock shell. At this time, the internal state is as follows Figure 5 As shown, the control cylinder 1001 is then operated to retract, and the control cylinder 1001 can drive the brake plate 1002 to move downward. When the brake plate 1002 moves downward, it can drive the lower end of the linkage plate 1003 to move downward, so the inclination angle of the linkage plate 1003 becomes smaller and drives the side in contact with the stamping sheet 7 to move downward. At the same time, the two ends of the linkage plate 1003 can rotate adaptively. Since the connecting block 9 at the bottom of the other side of the stamping sheet 7 is rotatably connected with the mounting support rod 8 through the shaft rod, the stamping sheet 7 rotates with the connecting shaft, so that the shape changes of the two stamping sheets 7 can be adjusted and controlled. At the same time, during the downward movement of the brake plate 1002 The pressure rod 17 can also move downward, so the pressure rod 17 can be continuously moved to one side of the U-shaped groove 16, so that the hydraulic cylinder 4 in the U-shaped groove 16 can be pushed downward, so that under the action of pressure, the hydraulic oil 18 can enter the other side of the U-shaped groove 16 and enter the placement chamber 14, and under the action of hydraulic pressure, the square push piece 1303 can be pushed to squeeze the limit spring 1304 and move upward, so the stamping arc piece 1301 can be pushed upward by the push rod 1302, so that the stamping piece 7 and the stamping arc piece 1301 can change their positions at the same time, and finally the stamping arc piece 1301 can be moved above the stamping piece 7. At this time, the internal state is as follows Figure 6 As shown, the hydraulic cylinder 4 is then controlled to retract again, and the hydraulic cylinder 4 can drive the mounting plate 3 and the punching block 6 to move upward, and the punching arc piece 1301 can contact the two sides of the luggage lock shell and cooperate with the arc edges on the top of the punching groove 2 to squeeze the two sides of the luggage lock shell into an arc shape. At this time, the luggage lock shell is in the state of Figure 7 As shown, the secondary stamping operation can be completed after a short molding, and then the electric telescopic rod 2502 is controlled to retract, so that the sealing sheet 2503 can be reset and no longer adsorb and position the luggage lock shell, and the hydraulic cylinder 4 is controlled to extend. The hydraulic cylinder 4 can push the mounting plate 3 downward, and the stamping block 6 and the luggage lock shell can be moved out of the stamping groove 2, and then the luggage lock shell can be removed. Finally, the control cylinder 1001 is adjusted to reset to the extended state, so that the stamping sheet 7 and the stamping arc sheet 1301 can be reset to the initial state, so as to facilitate the next operation.
