Description

Technical Field

[0001] The present invention belongs to the technical field of stamping feeding equipment, and particularly relates to a feeding device for bar stamping. Background Art

[0002] With the rapid development of the processing industry, enterprises pursue efficient, automatic, and environmentally friendly production methods. An important means is to use automatic equipment to replace manual operations, which greatly improves production efficiency and reduces labor costs. In the past, the processing of bar materials usually used manual feeding, which not only had a high labor intensity and low operation efficiency for workers, but also had low feeding accuracy, making it difficult to ensure processing quality, and at the same time there were relatively large safety hazards.

[0003] The emergence of the bar conveying mechanism has solved the problems of high labor intensity and low production efficiency in the past. During the hot forging process, it is necessary to heat the bar material in advance to make it softer for stamping. In the actual production process, manual loading and unloading are usually relied on. Since a large amount of heat is generated during the heating of the bar material by the high-frequency heating furnace, unexpected situations during operation may cause burns to workers; and the bar material is relatively heavy, and manual loading is time-consuming and laborious, resulting in a reduction in the heating efficiency of the bar material.

The stock bin is inclined as a whole with the front end lower and the rear end higher. Two chutes are symmetrically arranged on the front end face of the stock bin, and the two chutes extend to the lower end face of the stock bin. The lifting device includes a mounting base, the lower end of the mounting base extends to the lower side of the stock bin, the mounting base is longitudinally arranged and is located on the front end face of the stock bin in the middle of the two chutes.

A lifting flap is provided on the pin shaft, and the lifting flap is rotatably connected to the pin shaft. The connection position between the pin shaft and the lifting flap is located at the upper front side of the lifting flap. The positions of the two lifting flaps correspond to the positions of the two chutes.

[0017] Embodiment: A feeding device for bar stamping, as Figures 1-4As shown, it includes a storage bin 1 and a material lifting device. The storage bin 1 is inclined as a whole with the front end lower and the rear end higher. Two sliding grooves 2 are symmetrically opened on the front end face of the storage bin 1, and the two sliding grooves 2 extend to the lower end face of the storage bin 1. The material lifting device includes a mounting base 3. The lower end of the mounting base 3 extends to the lower side of the storage bin 1. The mounting base 3 is longitudinally arranged and is provided on the front end face of the storage bin 1 in the middle of the two sliding grooves 2. A linear slide rail 4 is provided at the front end of the mounting base 3. The linear slide rail 4 is arranged parallel to the two sliding grooves 2. A sliding group is provided on the linear slide rail 4. The sliding group includes two sliding blocks 5. The two sliding blocks 5 are slidably connected to both sides of the linear slide rail 4. At the upper ends of the outer end faces of the two sliding blocks 5, a pin shaft 6 is provided. The pin shaft 6 is fixedly connected to the sliding block 5. A material lifting flap 7 is provided on the pin shaft 6. The material lifting flap 7 is rotatably connected to the pin shaft 6. The connection position between the pin shaft 6 and the material lifting flap 7 is located at the upper front side of the material lifting flap 7. The positions of the two material lifting flaps 7 correspond to the positions of the two sliding grooves 2. A grid baffle 8 is connected between the two sliding blocks 5. The grid baffle 8 is fixedly connected to the two sliding blocks 5. The left and right ends of the grid baffle 8 extend to the left and right sides of the sliding blocks 5 and simultaneously abut against the front end faces of the two material lifting flaps 7. At the upper and lower ends of the front end face of the storage bin 1, a mounting seat 9 is provided. A driving motor 10 is provided on the mounting seat 9 located at the lower side. A lead screw 11 is provided between the two mounting seats 9. The lead screw 11 is arranged parallel to the linear slide rail 4 and is rotatably connected to the two mounting seats 9 at both ends. The drive of the driving motor 10 is fixedly connected to the lower end of the lead screw 11. A lead screw nut 12 is provided on the lead screw 11. The lead screw nut 12 is fixedly connected to the two sliding blocks 5.

[0018] A material guiding frame 13 is provided on the mounting seat 9 located at the upper side. The upper end of the material guiding frame 13 is flush with the upper end face of the mounting seat 9 located at the upper side; the upper surface of the mounting seat 9 located at the upper side is flush with the top surface of the storage bin 1; when the sliding group moves to the uppermost end, the upper end faces of the two material lifting flaps 7 are flush with the top surface of the storage bin 1; when the sliding group moves to the lowermost end, the two material lifting flaps 7 are located at the lower side of the storage bin 1.

[0019] Principle of the present invention: During use, the feeding device is installed on one side of the heating furnace, and the bar stock to be heated is placed in the storage box 1. Since the storage box 1 is arranged with the front end lower and the rear end higher, the bar stock will accumulate at the front side of the storage box 1. Control the rotation of the driving motor 10, drive the lead screw nut 12 to move up and down through the lead screw 11, and then drive the sliding group to move up through the lead screw nut 12. The lifting flap 7 moves up into the storage box 1 to lift the bar stock in the storage box 1. The sliding group continues to rise to drive the bar stock to be lifted upward. When the sliding group moves to the uppermost end, the two lifting flaps 7 are flush with the upper mounting seat 9. The lifted bar stock rolls forward from the lifting flap 7, rolls onto the mounting seat 9, and then rolls into the heating furnace through the material guiding frame 13 for heating. After the lifting is completed, the driving motor 10 controls the sliding group to descend. The descending lifting flap 7 will re-enter the storage box 1. Since the bar stock will block the lifting flap 7, the lifting flap 7 will rotate around the pin shaft 6 and turn up to facilitate downward movement. After moving to the bottom of the storage box 1, the lifting flap 7 returns to the horizontal state again after losing the block of the bar stock, and can continue to lift the bar stock in the storage box 1.

[0020] Finally, it should be pointed out that the above embodiments are only relatively representative examples of the present invention. Obviously, the present invention is not limited to the above embodiments and there can be many variations. Any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention should be considered as belonging to the protection scope of the present invention.
