[0032] Reference Figure 1 , Figure 2 and Figure 3 The utility model provides an embodiment: a hardware stamping and bending forming device, including a workbench 1, an operating column 3 is fixedly connected to the left side of the top wall of the workbench 1, an electric telescopic rod 4 is fixedly connected to the top of the operating column 3, and a support frame 5 is fixedly connected to the bottom end of the electric telescopic rod 4. The support frame 5 is slidably connected to the right side of the operating column 3, and a hydraulic column 6 is fixedly connected to the bottom end of the support frame 5. An engaging groove 7 is fixedly connected to the bottom end of the hydraulic column 6. A punch 8 is slidably connected to the inner wall of the engaging groove 7. The punch 8 The top wall and the inner wall of the meshing groove 7 are fixedly connected with a one-way clamping tooth 9, the meshing groove 7 and the middle of the punch 8 are penetrated with a threaded locking pin 10, the middle of the top wall of the workbench 1 is fixedly connected with a locking groove 11, the inner wall of the locking groove 11 is fixedly connected with a die 12, the front and rear sides of the top walls of the locking groove 11 and the die 12 are penetrated with a three-pronged fixing pin 13, the side away from the two three-pronged fixing pins 13 and the front and rear sides of the locking groove 11 are penetrated with a three-pronged locking pin 14, and a high-pressure impact collecting mechanism 2 is arranged on the left side of the workbench 1;

[0033] Specifically, the workbench 1 provides a solid and stable working environment for the entire device to ensure that no shaking or deformation occurs during the stamping process. The electric telescopic rod 4 at the top of the operating column 3 adjusts the height of the support frame 5 so that the hydraulic column 6 and the meshing groove 7 are located in appropriate positions, and the punch 8 is engaged in the meshing groove 7 by sliding, and the one-way tooth 9 on the top wall is engaged with the one-way tooth 9 on the inner wall of the meshing groove 7, so that the position of the punch 8 is semi-fixed, and the threaded locking pin 10 passes through the middle of the punch 8 and the meshing groove 7 to lock it. At the same time, the die 12 is locked by the three-pronged locking pin 10. The fixing pin 13 is fixed in the locking groove 11, and the three-pronged locking pin 14 is used to further lock the position of the die 12 to prevent displacement during the stamping process. When the die 12 needs to be replaced or repaired, the three-pronged locking pin 14 only needs to be pulled out, and then the three-pronged fixing pin 13 can be pulled out upward to easily remove the die 12. When stamping and bending are required, the hydraulic column 6 pushes the punch 8 to move downward and cooperates with the die 12 to complete the stamping and bending of the hardware, thereby realizing the rapid disassembly and installation of the punch 8 and the die 12, greatly improving work efficiency and convenience.

[0034] Reference Figure 2 and Figure 4 The high-pressure impact collection mechanism 2 includes an air pump 201, the right end of the air pump 201 is connected with an air guide pipe 202, a supercharger 203 is fixedly installed in the middle of the air guide pipe 202, a valve controller 204 is fixedly connected to the right end of the supercharger 203, the right end of the air guide pipe 202 is connected to the left side of the locking groove 11, the right end of the bottom of the air guide pipe 202 is connected with a shunt pipe 205, a bottom hole 206 is opened in the middle of the inner bottom wall of the die 12, the right end of the shunt pipe 205 is connected with the bottom end of the bottom hole 206, and the right side of the locking groove 11 is connected with a guide groove 207;

[0035] Specifically, the high-pressure gas generated by the air pump 201 flows to the locking groove 11 through the air guide pipe 202. A supercharger 203 is installed in the middle of the air guide pipe 202, which can effectively enhance the pressure of the gas and ensure the strength of the subsequent impact. The valve controller 204 is responsible for accurately controlling the flow rate and flow velocity of the gas to ensure that the high-pressure gas is released into the locking groove 11 at the appropriate time. When the high-pressure gas enters the diverter pipe 205 through the air guide pipe 202, a strong impact force will be formed to blow the processed hardware out of the bottom hole 206 at the bottom of the die 12, ensuring that the hardware can be completely separated from the mold. The blown-out hardware is collected together under the guidance of the positive wind force at the right end of the air guide pipe 202 and the guide groove 207. The design of the guide groove 207 can ensure that the hardware falls into the collection area in an orderly manner, realizing efficient and accurate collection of hardware, and greatly improving production efficiency and product quality.

[0036] Reference Figure 1 , Figure 2 and Figure 5The right end of the workbench 1 is fixedly connected to a limiting frame 15, and a collection trolley 16 is arranged on the inner wall of the limiting frame 15, and a plurality of universal wheels 17 are fixedly installed on the bottom wall of the collection trolley 16 at equal intervals; a hand support rod 18 is fixedly connected to the right side of the collection trolley 16, and a non-slip sleeve 19 is fixedly connected to the right end of the hand support rod 18; a plurality of fixed feet 20 are fixedly connected to the front and rear sides of the workbench 1, and a plurality of threaded rods 21 are threadedly connected to the inner walls of the plurality of fixed feet 20, and a plurality of anti-slip pads 22 are fixedly connected to the bottom ends of the plurality of threaded rods 21, and a rotating block 23 is fixedly connected to the top ends of the plurality of threaded rods 21;

[0037] Specifically, the limit frame 15 is used to limit the position of the collection cart 16 on the right side of the workbench 1 to ensure that the collection cart 16 does not move excessively or deviate from the predetermined position during the movement. The collection cart 16 is used to collect the hardware after stamping and bending, which is convenient for subsequent handling and processing. The universal wheel 17 at the bottom enables the collection cart 16 to be easily moved in the working area, so as to facilitate the transportation of the hardware after stamping and bending to the designated position. The hand support rod 18 provides a handrail for the operator to push the collection cart 16, and the anti-slip sleeve 19 increases the friction between the operator's hand and the hand support rod 18 to prevent inconvenience or danger caused by sliding during the pushing process. The fixed foot 20 can adjust the height of the workbench 1 by twisting the rotating block 23 to rotate the threaded rod 21, and the anti-slip pad 22 can increase the friction between the workbench 1 and the ground to prevent displacement caused by vibration or external force during the working process.

[0038] Reference Figure 1 , Figure 2 and Figure 3 The front side of the workbench 1 is fixedly connected with a console 24, and a plurality of control buttons 25 are fixedly installed on the top of the console 24; the front side of the hydraulic column 6 is fixedly connected with a pressure gauge 26, and the inner wall of the pressure gauge 26 is fixedly connected with a pressure pointer 27; the top ends of the two three-pronged fixing pins 13 are fixedly connected with a handle 28, and the ends of the two three-pronged locking pins 14 that are far away from each other are fixedly connected with a fixing plate 29;

[0039] Specifically, the control console 24 is the operation center of the entire device, and the control button 25 is used to adjust and control the start, stop, and adjustment of the stamping speed and force of the stamping and bending process. The pressure gauge 26 and the pressure pointer 27 are used to display the pressure generated by the hydraulic column 6 to ensure the accuracy and safety of the stamping and bending of hardware. The handle 28 and the fixing plate 29 serve as the holding and operation method of the three-pronged fixing pin 13 and the three-pronged locking pin 14, so that the operator can easily replace the die 12.

[0040] Working principle: The workbench 1 provides a solid and stable working environment for the whole device to ensure that there is no shaking or deformation during the stamping process. The electric telescopic rod 4 at the top of the operating column 3 adjusts the height of the support frame 5 so that the hydraulic column 6 and the meshing groove 7 are in the appropriate position. The punch 8 is engaged into the meshing groove 7 by sliding. The one-way tooth 9 on the top wall is engaged with the one-way tooth 9 on the inner wall of the meshing groove 7, thereby semi-fixing the position of the punch 8. The threaded locking pin 10 passes through the punch 8 and the meshing groove 7. The middle part is locked, and the die 12 is fixed in the locking groove 11 by the three-pronged fixing pin 13, and the three-pronged locking pin 14 is used to further lock the position of the die 12 to prevent displacement during the stamping process. When the die 12 needs to be replaced or repaired, just pull out the three-pronged locking pin 14 first, and then pull the three-pronged fixing pin 13 upward to easily disassemble the die 12. When stamping and bending are required, the hydraulic column 6 pushes the punch 8 to move downward and cooperate with the die 12 to complete the stamping and bending of the hardware.

[0041] And the high-pressure gas generated by the air pump 201 flows to the locking groove 11 through the air guide pipe 202. A supercharger 203 is installed in the middle of the air guide pipe 202, which can effectively enhance the pressure of the gas and ensure the strength of the subsequent impact. The valve controller 204 is responsible for accurately controlling the flow and flow rate of the gas to ensure that the high-pressure gas is released into the locking groove 11 at the appropriate time. When the high-pressure gas enters the diverter pipe 205 through the air guide pipe 202, a strong impact force will be formed to blow the processed hardware out of the bottom hole 206 at the bottom of the die 12, ensuring that the hardware can be completely separated from the mold. The blown-out hardware is collected together under the guidance of the positive wind force at the right end of the air guide pipe 202 and the guide groove 207. The design of the guide groove 207 can ensure that the hardware falls into the collection area in an orderly manner.
