Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary equipment for thread rolling machines, in particular to an automatic feeding device for thread rolling machines. Background Art

[0002] The thread rolling machine is a multifunctional cold extrusion forming machine tool, which can perform thread, straight grain, diagonal grain rolling, straight tooth, helical tooth and helical spline gear rolling, straightening, diameter reduction, rolling and various forming rolling treatments on the workpiece in the cold state within its rolling force range.

[0003] An existing automatic feeding device for a thread rolling machine (publication number: CN220943020U) has at least the following disadvantages: the above-mentioned device is provided with a feeding hopper and a feeding roller. When a single steel bar can be transported to the feeding barrel through the gap between the feeding hopper and the feeding roller, and then pushed to the thread rolling machine through the feeding plate, but since the position of the feeding roller is fixed, the size of the gap between the feeding hopper and the feeding roller is fixed, resulting in the feeding roller being able to feed only steel bars of a single diameter, and since there is no mechanism to prevent steel bars from leaking at the feeding hopper, when the previous steel bar is transported to the feeding barrel, there is a certain probability that the subsequent steel bars will fall into the feeding barrel from the gap between the feeding hopper and the feeding roller immediately after the previous steel bar, resulting in the inability of the thread rolling machine to collect the material. For this reason, the present utility model is proposed. Utility Model Content

[0023] In this embodiment, a rodless cylinder is fixed to the top surface of the feeding platform 1, and a push plate 204 is fixed to the top surface of the rodless cylinder slider, and the push plate 204 is set to slide inside the sliding bin 203, and a first electric push rod is fixed to the left side of the feeding platform 1, and one end of the telescopic rod of the first electric push rod is fixed to the left side of the movable frame 201, and a motor is fixed to the front side of the movable frame 201, and the output shaft of the motor extends to the inside of the movable frame 201, and a gear is fixed to the output shaft end of the motor, and a gear is fixed to the end of the unloading roller 202 close to the front side of the movable frame 201, and the gear of the motor and the gear of the unloading roller 202 are meshed and driven by a toothed belt, and by setting the feeding bin 101, all the steel bars are stored in the inside of the feeding bin 101, and then a large amount of steel bars are piled up above the connecting bin 2. Then, by starting the first electric push rod, the movable frame 201 and the unloading roller 202 are driven to move, so that a gap is left between the unloading roller 202 and the connecting bin 2 that only supports the passage of a single steel bar. Subsequently, the unloading roller 202 is driven to rotate by the motor, thereby helping the single steel bar to fall from the connecting bin 2 into the sliding bin 203. Subsequently, the first electric push rod resets the unloading roller 202 to prevent excess steel bars from falling and causing leakage. At this time, the rodless cylinder can be started to drive the push plate 204 to push the steel bars inside the sliding bin 203 into the thread rolling machine for processing, effectively avoiding the uncontrollable unloading interval when the feeding bin 101 is unloading, resulting in leakage. At the same time, the unloading roller 202 can move freely, so that controllable loading of steel bars of different thicknesses can be achieved, thereby increasing the applicability of the device.

[0026] In this embodiment, two limit rods 301 are slidably inserted on the front side of the feeding bin 101, and one end of the limit rod 301 is fixed to one side of the positioning plate 3. By setting the limit rod 301, the movement of the positioning plate 3 can be limited, making the movement of the positioning plate 3 more stable.
