The embodiment of the utility model provides a steel bar cutting machine and trigger device thereof, the steel bar cutting machine comprises a cutting mechanism, a conveying mechanism, a material moving mechanism, a storage mechanism and a trigger device, wherein, the conveying mechanism is used for conveying the steel bar 10 to be cut off, the steel bar 10 is moved along a feeding track 20, the cutting mechanism is arranged in the direction of the conveying mechanism moving towards the steel bar 10 (as the arrow direction shown in figure 1 and figure 2, the conveying mechanism conveys the steel bar 10 to move forwards, the cutting mechanism is arranged in front of the conveying mechanism), when the steel bar 10 moves forwards along the feeding track 20 to the front end thereof and reaches the preset length from the cutting position of the cutting mechanism, the travel switch 3 of the trigger device is triggered by the steel bar 10 and sends a cutting signal to the cutting mechanism, so that the cutting mechanism can cut off the steel bar 10 from the cutting position, so as to accurately obtain the steel bar 10 with the preset length, and then the material moving mechanism moves the cut steel bar 10 to the material storage mechanism, and then the next section of steel bar 10 is cut off continuously.
Specifically, the triggering device comprises a sliding piece 1 and a travel switch 3 which are arranged on the feeding track 20, wherein the travel switch 3 is connected with the cutting mechanism, and after the travel switch 3 is triggered, a cutting signal can be sent to the cutting mechanism, so that the cutting mechanism cuts off the steel bar 10 at a cutting position, and the steel bar 10 with a preset length is obtained. The sliding part 1 slides along the slideway, the sliding direction of the sliding part 1 is parallel to the length direction of the feeding track 20, the sliding part 1 comprises a sliding rod 11 and a striker 12 which are connected, wherein the sliding rod 11 can slide along the slideway, and one end of the striker 12 is positioned in the feeding track 20 and can slide along the feeding track 20; when the steel bar 10 moves forwards along the feeding track 20, the steel bar can impact the plunger 12 and can push the slide rod 11 to slide forwards along the slide way to act with the contact 31 of the travel switch 3 so as to trigger the travel switch 3.
In detail, when the steel bar 10 moves forwards along the feeding track 20, the front end of the steel bar can collide with one end of the plunger 12, which is located in the feeding track 20, after the collision, under the pushing action of the steel bar 10, the plunger 12 moves forwards along the feeding track 20, and the sliding rod 11 slides forwards along the slideway and acts with the contact 31, and triggers the travel switch 3.
