DETAILED DESCRIPTION

[0026] The technical solution of the present invention is further described in detail below in conjunction with the drawings and specific embodiments of the specification. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0027] Example 1

[0028] Refer to the attached Figure 1-4 The present application provides a multi-station continuous stamping device, including a stamping machine 1, a base 2 and an operating table 6. The base 2 is provided with a driving mechanism, and the operating table 6 is provided with a knocking mechanism, which is used to cause the operating table 6 to vibrate. The knocking mechanism includes a turntable 14 and a swing rod 20. The driving mechanism is used to drive the operating table 6 and the turntable 14 to rotate. The outer portion of the turntable 14 is provided with a plurality of protrusions 1401. The turntable 14 drives the protrusions 1401 to rotate to push the swing rod 20 to deflect. The top of the swing rod 20 is fixedly connected There is a hammer head 19, and the rocker arm 20 drives the hammer head 19 to hit the operating table 6 through its own deflection. Since the rocker arm 20 is elastic, it will quickly return to its original state due to its own elastic force after being pushed and bounced by the protrusion 1401. At this time, the rocker arm 20 will pull the hammer head 19 to hammer the operating table 6, and this will be repeated to cause the operating table 6 to vibrate, thereby facilitating the separation of the workpiece and the stamping die. A number of stamping dies 5 are arranged on the operating table 6, and the turntable 14 adjusts the alignment of the several stamping dies 5 with the stamping machine 1 one by one through its own rotation.

[0029] Preferably, a buckle 7 is fixedly connected to the bottom end of one side of the punching machine 1 close to the base 2, a positioning groove 25 is fixedly connected to the inner wall of one side of the buckle 7, a plurality of spring leaves 26 are fixedly connected in the positioning groove 25, and a fixing pile 24 is fixedly connected to one side of the spring leaf 26. The spring leaf 26 can maintain the fixing pile 24 in the middle of the buckle 7 under normal conditions, so it can be used to clamp the plug 27 to maintain the stability between the base 2 and the punching machine 1 when the plug 27 is inserted in the buckle 7. A circular through hole is opened on the other side of the buckle 7, and a button 22 is provided at the circular through hole of the buckle 7. A connecting pile 23 is fixedly connected in the middle between the button 22 and the fixing pile 24.

[0030] Preferably, a plug 27 is fixedly connected to one side of the base 2 close to the punching machine 1, one end of the plug 27 extends to the inside of the buckle 7, a bayonet is provided at one end of the plug 27 in the buckle 7, a notch is provided at the end of the plug 27 at the bayonet, the diameter of the connecting pile 23 is smaller than the diameter of the fixing pile 24, the width of the notch is equal to the diameter of the connecting pile 23, and the diameter of the fixing pile 24 is equal to the diameter of the bayonet.

[0031] When using this device, the operating table 6 can be pushed to move to the punching machine 1, and the base 2 can be placed against the outer wall of the punching machine 1, and the insert 27 can be inserted into the buckle 7. In this process, the button 22 can be pressed to make the fixing pile 24 enter the positioning groove 25. At this time, the connecting pile 23 will be in the gap on the insert 27, so the insert 27 can be pushed to be installed on the outside of the connecting pile 23, and then the button 22 can be released, and the elastic force of the spring sheet 26 can be used to push the fixing pile 24 out of the positioning groove 25. At this time, the fixing pile 24 will be in a state of penetrating the insert 27, so the insert 27 can be maintained in a state of being inserted into the buckle 7, thereby ensuring that the base 2 and the punching machine 1 are in a relatively fixed state.

[0032] Preferably, a motor 21 is fixedly connected to the inner wall of one side of the base 2, a worm 9 is fixedly connected to one end of the output shaft of the motor 21, a rotating shaft 10 is rotatably connected to one side of the inner wall of the bottom end of the base 2, the outside of the rotating shaft 10 is connected to a first gear 11 and a worm wheel 12 by a key, the worm wheel 12 is meshed with the worm 9, and the outside of the rod body of the rotating rod 3 in the base 2 is connected to a second moving wheel 8 by a key, the second moving wheel 8 is meshed with the first gear 11, and the diameter of the second moving wheel 8 is larger than the diameter of the first gear 11.

[0033] Then the punching machine 1 and the motor 21 can be started. After starting, the motor 21 can drive the worm wheel 12 to rotate through the worm 9. The worm wheel 12 drives the first gear 11 to rotate through the rotating shaft 10. The first gear 11 drives the rotating rod 3 to rotate through the second moving wheel 8. The rotating rod 3 can drive the operating table 6 and the third gear 15 to rotate. The operating table 6 can drive the stamping die 5 to rotate at the bottom of the punching head of the punching machine 1 through its own rotation. Therefore, the operation of the punching machine 1 can align with each stamping die 5 in turn, and punch the workpieces on the stamping die one by one.

[0034] Preferably, the driving mechanism includes a rotating rod 3, which is rotatably connected to the middle of the inner wall at the bottom end of the base 2. A circular opening is provided at the middle of the top end of the base 2. The top end of the rotating rod 3 extends to the outside of the base 2 at the circular opening. The operating table 6 is fixedly connected to the top end of the rotating rod 3. The stamping die 5 is equidistantly fixedly connected to the outer side of the top end of the operating table 6. The stamping machine 1 is rotatably connected to a roller 101 at the bottom end of the operating table 6.

[0035] Since the operator can load and unload the remaining stamping dies 5 simultaneously when the stamping machine 1 is stamping a certain stamping die 5, the use of this device can simultaneously perform loading, stamping and unloading, thereby improving the efficiency of the stamping process.

[0036] Preferably, a plurality of support rods 4 are equidistantly fixedly connected to the outer side of the top of the base 2, the top of the support rod 4 close to the punching machine 1 is rotatably connected to the base 17, and the top of the support rod 4 away from the punching machine 1 is fixedly connected to the support 13, and the top of the support 13 and the base 17 are both provided with spherical grooves, and the support 13 and the base 17 are both provided with balls 18 in the spherical grooves, and the balls 18 are tangent to the bottom surface of the operating table 6.

[0037] When the operating table 6 is controlled to rotate to rotate different stamping dies 5, the rotation of the third gear 15 can drive the fourth gear 16 to rotate, and the fourth gear 16 drives the turntable 14 to rotate through the base 17. The rotation of the turntable 14 can push the pendulum 20 to deflect through the protrusion 1401. Since the pendulum 20 will recover due to its own elastic force after deflection, the deflection and recovery process of the pendulum 20 can drive the hammer head 19 to continuously strike the operating table 6, thereby causing it to vibrate. The vibration can cause the stamping die 5 to vibrate, so that the workpiece that has been stamped on the stamping die 5 can be separated from it, thereby facilitating the work of removing the workpiece after stamping.

[0038] Preferably, the outside of the base 17 is connected to the fourth gear 16 and the turntable 14 through a key, and the third gear 15 is connected to the top end of the outside of the rod body of the rotating rod 3 through a key, the third gear 15 is meshed with the fourth gear 16, the diameter of the third gear 15 is larger than the diameter of the fourth gear 16, the protrusion 1401 is equidistantly fixedly connected to the outside of the turntable 14, the protrusion 1401 is hemispherical, the rocker arm 20 is made of elastic material, and the rocker arm 20 is fixedly connected to the top end of one side of the support rod 4 at the bottom of the base 17.

[0039] Since the rocker arm 20 and the hammer head 19 are only arranged on the support rod 4 near the stamping machine 1, the vibration generated by the hammer head 19 hitting the operating table 6 has a greater impact on the stamping die 5 near the stamping machine 1, and since the above-mentioned vibration only occurs during the rotation and adjustment of the operating table 6, it is possible to avoid positional discrepancy between the workpiece that has not yet been stamped and the stamping die 5 in which it is located, thereby causing stamping failure.

[0040] Example 2

[0041] See attached Figure 5 The present application provides a multi-station continuous stamping device. Compared with Example 1, in order to facilitate the maintenance or replacement of the stamping die 5, a plurality of mounting grooves are equidistantly opened on the outer side of the operating table 6. The number of the stamping dies 5 is the same as the number of the mounting grooves and corresponds one to one. The operating table 6 is provided with a plurality of through holes in the mounting grooves. The operating table 6 is provided with bolts 28 at the through holes. The bottom end of the stamping die 5 is provided with a threaded groove at the through hole. The bolt 28 is threadedly connected to the stamping die 5 at the threaded groove.

[0042] The stamping die 5 can be placed in the mounting groove on the operating table 6, and then the stamping die 5 can be fixedly connected to the operating table 6 by bolts 28; conversely, by loosening the bolts 28, the stamping die 5 can be removed to facilitate its maintenance or replacement.

[0043] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto.
