Automatic feeding mechanism for steel wire thread inserts

The utility model discloses an automatic feeding mechanism for a steel wire thread insert. The automatic feeding mechanism mainly comprises a vibration sieve, a linear vibration feeder, a cutting mechanism, a horizontal cutting cylinder and a feeding cylinder, the vibration sieve is connected with the cutting mechanism through the linear vibration feeder; the cutting mechanism is provided with two rails which are connected at an angle of 90 degrees, one rail receives the steel wire thread inserts conveyed by the linear vibration feeder, and the first steel wire thread insert is pushed to an operation waiting area at the joint of the two rails through a horizontal cutting air cylinder fixed to the rear end of the rail. The feeding air cylinder pushes the steel wire thread insert located in the operation waiting area to the outlet position of the cutting mechanism along the other rail. According to the automatic press-fitting device, the steel wire thread insert of one type can be automatically and accurately c
