[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] This utility model provides, for example Figure 1-4 The diagram shows a fully automated production line for ventilation duct elbows. The production process of the ventilation duct elbows includes the following units in the order of operation: raw material feeding area 15, feeding mechanism 16, first robot 17, punch press 18, second robot 19, forming unit 20, third robot 21, palletizing platform 22, and warehouse 23. The punch press 18 includes a stamping machine tool 1, in which a first robot 17 picks up the workpiece to be stamped from the feeding mechanism 16 and places it on the stamping machine tool 1 to wait for the stamping operation; Among them, a control box 2 for controlling and adjusting the stamping operation of the stamping machine tool 1 is fixedly installed on the lower right outer wall of the stamping machine tool 1. A stamping operation cavity 9 is opened in the middle inner side of the stamping machine tool 1. A stamping block 4 is connected to the upper outer wall of the stamping operation cavity 9 and the inside of the stamping machine tool 1. A rotating seat 7 is movably installed on the lower outer side of the stamping operation cavity 9. Mold cavities 6 are opened in the left and right ends of the rotating seat 7 respectively.

[0022] A stamping die 5 is provided on the lower side of the stamping block 4. The stamping die 5 and the die cavity 6 fit together. A hydraulic press is provided on the upper side of the stamping machine tool 1 to connect to the stamping block 4 and drive the stamping block 4 to move up and down in the stamping working cavity 9 of the stamping machine tool 1. Support seats 3 are provided at the four corners of the lower side of the stamping machine tool 1 for stable support. The raw material feeding area 15 is piled with workpieces to be stamped. The second robot 19 is used to grab the workpieces that have been stamped on the punch press 18. The forming unit 20 includes a hydraulic press and a bending die, which are used to further shape and bend the stamped workpiece; The third robot 21 is used to grab the workpieces that have completed the operation on the forming unit 20 and move them to the palletizing platform 22 to complete the palletizing. The palletizing platform 22 is equipped with a transport trolley for transporting the palletized products into the warehouse 23.

[0023] Specifically, a sheet separator is installed outside the raw material feeding area 15 to separate the stacked workpieces to be stamped into individual sheets, providing independent raw materials for subsequent robot gripping and avoiding equipment failure caused by multiple workpieces to be stamped entering the processing flow at the same time.

[0024] In this embodiment, the raw material feeding area 15 is used to store the workpieces to be stamped. The first robot 17 is equipped with a vacuum suction cup gripper for gripping the workpieces to be stamped. The first robot grabs a single sheet of material from the feeding mechanism 16 and accurately places it in the stamping frame 13 of the stamping machine tool 1 of the punch press 18, waiting for the stamping operation.

[0025] At this time, the punching machine 1 of the punch press 18 drives the punching block 4 to move downward through the hydraulic press. The punching die 5 on the lower side of the punching block 4 cooperates with the die cavity 6 to punch the sheet into a blank of half a bent pipe. Specifically, the hydraulic press converts hydraulic energy into mechanical energy to push the punching block 4 to generate high-intensity pressure, so that the sheet undergoes plastic deformation under the constraint of the punching die 5 and the die cavity 6 to form a preset blank shape. The first robot 17 controls the motion trajectory through the program to ensure the positional accuracy of the sheet and ensure the consistency of the punching dimensions.

[0026] The second robot 19 is equipped with a special fixture, which picks up the stamped half of the bent pipe blank from the stamping machine 1 of the punch press 18 and transfers it to the forming unit 20. The hydraulic press of the forming unit 20 drives the bending die to further bend and shape the blank to meet the angle and curvature requirements of the ventilation duct bend. The third robot 21 is equipped with a finished product fixture, which picks up the finished bend from the forming unit 20 and transfers it to the palletizing platform 22 for neat stacking. The transport trolley on the palletizing platform 22 transfers the stacked finished products to the warehouse 23 for storage.

[0027] like Figure 1-4As shown, the stamping machine tool 1 is powered by an external power source. A rotating base 14 is provided at the lower end of the rotating seat 7, and the rotating base 14 and the stamping machine tool 1 are connected with a clearance fit. The rotating seat 7 can rotate in the stamping machine tool 1 through the rotating base 14. A stamping frame 13 is fixed to the outside of the mold cavity 6 at the upper left and right ends of the rotating seat 7. The workpiece to be stamped by the first robot 17 is placed in the stamping frame 13. In the stamping working cavity 9, a partition 8 is fixed at a certain distance from the rotating seat 7, located at the middle upper side outside the rotating seat 7. The distance between the partition 8 and the rotating seat 7 is greater than the height of the stamping frame 13. A drive motor 10 is electrically connected and fixed inside the rear side of the stamping machine tool 1. An output shaft 12 is provided at the output end of the drive motor 10. A gear 11 is fixed on the middle outer side of the output shaft 12. The outer side of the rotating seat 7 adopts a meshing design. The rotating seat 7 and the gear 11 are on the same horizontal plane. The rotating seat 7 is connected to the gear 11 through meshing. The drive motor 10 drives the output shaft 12 to mesh with the rotating seat 7 through the gear 11, thereby driving the rotating seat 7 to rotate.

[0028] In the stamping machine tool 1, a slot is provided at the bottom of the stamping working cavity 9, and the height of the slot is greater than the height of the rotating seat 7 and the stamping outer frame 13.

[0029] Preferably, in this stamping machine tool 1, the first robot 17 mainly places the workpiece to be stamped in the stamping frame 13 of one of the mold cavities 6 of the rotating seat 7, and the stamping block 4 presses down to complete the stamping operation of this station. At the same time, the second robot 19 can grab the stamped workpiece in another empty mold cavity 6, realizing the parallel operation of two stations with one station performing stamping operation and the other station performing part picking operation, thereby improving the processing efficiency of a single stamping machine.

[0030] When the first robot 17 completes the workpiece placement and the stamping block 4 completes the stamping action, the drive motor 10 starts according to a preset time, driving the gear 11 to rotate through the output shaft 12. The preset time is mainly determined by the robot's gripping speed and the stamping operation time.

[0031] At this time, gear 11 meshes with the teeth of rotating seat 7, driving rotating seat 7 to rotate 180° around rotating base 14, rotating the stamped mold cavity 6 to the picking position of the second robot 19, and at the same time rotating the idle mold cavity 6 to the placing position of the first robot 17. In this process, the first robot 17 can immediately place a new workpiece to be stamped in the newly rotated empty mold cavity 6, while the second robot 19 simultaneously grabs the finished product in the mold cavity 6 that has been stamped, eliminating the wasted time of waiting for the robot to pick up the part in the traditional single-station punch press.

[0032] Specifically, the drive motor 10 converts electrical energy into mechanical energy, and transmits the rotational motion to the rotating seat 7 through the meshing transmission of the output shaft 12 and the gear 11, so as to realize the 180° rotation of the rotating seat 7. The rotating base 14 provides rotational support for the rotating seat 7, ensuring the stability and positioning accuracy of the rotation process.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
