detailed description

The present invention will be further described below in conjunction with the accompanying drawings and embodiments:

Referring to Figures 1 and 2, a bending machine includes a deceleration reversing device and an automatic bending forming device, and the deceleration reversing device 22 is mounted between the bending machine 20 and the internal combustion engine 21, and is decelerated by two stages. Power conversion is possible. The power of the internal combustion engine pulley is transmitted to the I-axis 2 through the input pulley 1, and the I-axis 2 is provided with a forward rotation gear 3, an intermediate reversing dial 4, a counter gear 5, a positive friction plate group 6, and an anti-friction plate group 7, When the joystick 8 rotates the fork 9, the fork 9 can be used to push the intermediate reversing dial 4 to compress the positive friction plate group 6, and the forward rotation gear 3 directly drives the gear 11 on the II shaft 10 to the small pulley 13, Therefore, the bending machine 20 is driven to rotate the workpiece forwardly; when the shifting fork 9 is used to move the intermediate reversing sleeve 4 to compress the anti-friction disc group 7, the counter gear 5 drives the transition gear 14 to rotate the II-axis gear 12, and then transmits to the small-belt pulley 13, Thereby, the bending machine 20 is driven to reverse the operation to achieve the purpose of discharging, and then the workpiece is removed, and the bending machine 20 is repeatedly operated. The joystick 8 realizes power reversal by externally connecting the pedal or the handle, and controls the positive and negative rotation of the table turntable to realize the bending and unloading work process of the workpiece. When controlled by the foot pedal 18, the transmission handle 15 is straightened by the tension spring 16 to cause the bending machine 20 to be in a reverse working state, which in turn can be controlled by the internal combustion engine throttle control line to override the clutch 17 in a stationary state or Working state, use the foot to gently press the foot pedal 18 to make the middle reversing dial 4 in the middle position, clamp the workpiece, after the workpiece is installed, step on the foot again, so that the intermediate reversing sleeve 4 is pressed positively. The friction plate group 6, the bending machine 20 completes the bending work, and then the foot pedal 18 is lightly released. Due to the action of the tension spring 16, the bending machine 20 is reversed to loosen the workpiece, and the loading and unloading work is completed. When the handle 19 is directly operated, the handle 19 is lifted up, and the operating lever 8 drives the shifting fork 9 to press the anti-friction sheet set 7 to cause the bending machine 20 to reverse. The handle 19 is pressed downward, and the operating lever 8 drives the shifting fork 9 The positive friction plate group 6 is pressed to cause the bending machine 20 to rotate forward. It is best to use the pedal type in the actual work, so that the operator's hands can better clamp the workpiece, which is safe and efficient.

Referring to Fig. 3, the automatic bending forming device on the bending machine comprises a panel 36 on which a working turntable 31 is mounted, a pin hole is arranged in the circumference of the working turntable 31, and a pin 32 is inserted into the pin hole, and the flexible wire 33-end It is fixed to the panel 36, and the other end of the cord 33 is connected to the clutch reversing operation handle 34, and the clutch reversing operation handle 34 is installed in the reduction gearbox 35.

The automatic bending forming device is designed by designing a special working turntable 31 and a pin 32 that is inserted into the working turntable 31, and is connected by a cord 33 to control the clutch shift on the reduction gear box 35 of the bending machine. To the operating handle 34, the speed reducer 35 is dynamically separated to control the bending condition of the processed product; that is, some pin holes are formed on the turntable 31 of the ordinary bending machine, and the beginning end of a flexible wire 33 is fixed on the bending machine panel 36, soft The terminal of the wire 33 is connected with the operating handle 34, and the pin 32 rotates with the turntable 31. When the pin 32 rotates, the beginning of the cord 33 can be touched, and the operating handle 34 is pulled to separate the power of the reduction gearbox 35; when the bending machine works When the turntable 31 stops working, a bending work is completed. When the working turntable 31 has enough holes, the time at which the pin shafts of different hole positions touch the beginning of the cord 33 is different, and the processed products with different bending angles (that is, different degrees of bending) can be obtained, and each small small The hole corresponds to a product with a relatively fixed angle. When mass-produced, it can improve efficiency, reduce the dependence of the molded product on the operator, and reduce the labor intensity of the operator.
