Description

Technical Field

[0001] The utility model relates to the technical field of feeding devices, in particular to a feeding device for a bolt thread rolling machine. Background Art

[0002] When processing the threads of rod-shaped threaded fasteners such as bolts, thread rolling machines are generally used. The thread rolling machine is a multifunctional cold extrusion forming machine tool. The thread rolling machine can process the workpiece into threads, straight grains, and diagonal grains through two rolling wheels in a cold state within its rolling force range. However, when the thread rolling machine currently processes the threads of bolts, it usually adopts the manual feeding method, placing the bolts one by one between the two rolling wheels, and finally rolling the bolts through the two rolling wheels. This feeding method is not only labor-intensive, but also inefficient, so it is not conducive to efficient production. Utility Model Content

[0036] Embodiment 2, on the basis of Embodiment 1, as Figure 1 , Figure 5 and Figure 6 shown, the inner bottom end surface of the feeding box body 5 is inclined downward to the right, and a small vibration motor 504 is fixedly installed on the right end surface of the feeding box body 5. Through the setting of the small vibration motor 504, during the feeding process, the small vibration motor 504 can be started by the controller 7, and then under the vibration of the small vibration motor 504, it can be avoided that the metal bolts 501 are stuck in the lower right discharge port of the feeding box body 5;

[0037] A U-shaped bracket 502 is fixedly connected to the outer right side of the feeding box body 5, and a metal proximity switch 503 is fixedly installed on the U-shaped bracket 502. The setting of the metal proximity switch 503 is used to sense the metal bolts 501 inside the feeding box body 5; the metal proximity switch 503, the small vibration motor 504, the second electric cylinder 601, the first electric cylinder 301, and the sound and light alarm 701 are all electrically connected to the controller 7.

[0038] The working principle of this embodiment is as follows: when using, when threading the metal bolt 501, firstly, a plurality of metal bolts 501 are placed inside the loading box body 5, and at least twenty metal bolts 501 can be placed inside the loading box body 5, and then a metal bolt 501 at the lower right side falls into the second rectangular opening 603 through the first rectangular opening 402 under the action of gravity; then, when loading is required, the second electric cylinder 601 is started through the controller 7, and the telescopic rod of the second electric cylinder 601 is controlled to extend to the right, thereby moving the L-shaped feeding plate 602 to the right, and a metal bolt 501 inside the second rectangular opening 603 is pushed into the loading box body 5 by the L-shaped feeding plate 602 moving to the right. The metal bolt 501 is pushed to the right into the U-shaped groove 305. At this time, the controller 7 starts the first electric cylinder 301 and controls the telescopic rod of the first electric cylinder 301 to extend backward, while the telescopic rod of the second electric cylinder 601 retracts to the left. During the backward extension of the telescopic rod of the first electric cylinder 301, the driving plate 302, the pushing column 307, the external spring of the pushing column 307, the pushing seat 304 and the metal bolt 501 inside the U-shaped groove 305 are moved backward, thereby pushing the metal bolt 501 inside the U-shaped groove 305 backward to between the two rolling wheels on the bolt thread rolling machine body 1, and then the thread rolling process can be carried out.

[0039] After a metal bolt 501 is threaded, it will fall downward onto the workbench on the bolt thread rolling machine body 1. A guide plate can be installed on the workbench of the bolt thread rolling machine body 1 to automatically guide the processed metal bolt 501 into the material box; then the metal bolt 501 inside the feeding box body 5 will automatically move to the lower right under the influence of gravity and the inclination of the feeding box body 5, and the metal bolt 501 inside the feeding box body 5 will be sensed by the metal proximity switch 503. When the metal proximity switch 503 cannot sense the metal bolt 501, it means that the number of the metal bolt 501 inside the feeding box body 5 is small. At this time, the controller 7 will start the sound and light alarm 701, and the started sound and light alarm 701 will provide an effective warning to the staff, reminding the staff to replenish the metal bolt 501 in the feeding box body 5 in time.
