Description

Technical Field

[0001] The present invention relates to the technical field of transportation in intelligent heat treatment production lines, and particularly relates to a handling device for stainless steel bars. Background Art

[0002] In an intelligent heat treatment production line, after stainless steel bars are processed through processes such as high-temperature quenching and tempering, they need to be transferred to the next process for finishing. Currently, the handling devices for stainless steel bars commonly used in the industry, although having improved efficiency and safety compared to traditional manual handling, are difficult to meet the automation connection requirements of intelligent heat treatment production lines.

[0003] This device requires manual or mechanical assistance to manually sort and arrange the high-temperature bars after heat treatment, which not only leads to bottlenecks in production efficiency but also may cause safety hazards due to frequent human-machine interactions in high-temperature environments; when dealing with bars with large diameter differences, the existing handling devices lack intelligent recognition and adaptive functions, and the clamping mechanisms of traditional handling devices are likely to cause damage to the surface oxide layer of the material, affecting the quality of the final product; how to achieve the rapid transfer of bars after heat treatment has become a technical problem that urgently needs to be solved in promoting the full-process automation of metal material processing.

When the present invention is in use, when loading and unloading after the heat treatment production line is completed, it is not necessary to manually or with the aid of tools to arrange the bars in sequence on the support plate. Instead, by adjusting the angle of the support plate, the support plate is tilted upward or downward, so that the bar stock automatically rolls down and arranges on the support plate, which can automatically adapt to bars of different diameters, greatly saving costs and improving efficiency; when the bar stock is loaded and unloaded, the buffer mechanism can effectively decelerate the bar stock during sliding, thereby preventing the impact during the arrangement of the bar stock from causing bumps, and the buffer direction of the buffer mechanism can be adjusted, so that it can be used both when loading and unloading.

[0033] In an optional implementation manner of the embodiment of the present invention, as Figure 11 As shown, the intermittent toggle assembly includes: a transmission shaft II 21, a dial wheel 22, a compression spring III 23, and a buckle II 24; the transmission shaft II 21 is slidably installed in an arc-shaped slide groove on the limit frame 15, and two dial wheels 22 are provided, both of which are fixedly installed on the transmission shaft II 21; the compression spring III 23 is installed on the transmission shaft II 21, and the buckle II 24 is slidably installed on the transmission shaft II 21, and the short shafts at both ends of the buckle II 24 are clamped in the grooves on both sides of the limit frame 15.

[0034] In an optional implementation manner of the embodiment of the present invention, as Figure 5 As shown, both ends of the groove on the side of the sliding frame 2 are provided with grooves extending upwards, so as to limit the lever 5.

[0035] In an alternative embodiment of the embodiment of the present invention, as Figure 7 shown, the bending angle of the upper surface of the buffer plate 3 is 160 degrees.

[0036] In an alternative embodiment of the embodiment of the present invention, as Figure 8 shown, the upper surface of the friction block 10 is made of rubber material and is provided with protrusions, so as to increase the friction force.

[0037] Working principle: When the present invention is in use, when loading materials, first adjust the support plate 1 to be tilted upward to facilitate the rolling of the bar. Specifically, manually pull the buckle Ⅰ 20 at both ends outward, the compression spring Ⅱ 18 is compressed, and after the short shafts at both ends of the buckle Ⅰ 20 are disengaged from the card slots on both sides of the limit frame 15, lift upward at the same time. When a certain angle is lifted, release the buckle Ⅰ 20, and the buckle Ⅰ 20 slides inward under the action of the reset of the compression spring Ⅱ 18, so that the short shafts at both ends of the buckle Ⅰ 20 are stuck in the card slots at a higher position on the limit frame 15 to complete the fixation.

[0038] Next, place the bar at the outer end of the support plate 1, and the bar rolls backward along the upper surface of the support plate 1. When rolling, the bar will pass through the buffer plate 3. Since the buffer plate 3 has a certain angle, it will play a role in decelerating the bar. When the bar passes through the middle of the buffer plate 3, due to the gravity of the bar, it will press the buffer plate 3 to rotate. When the buffer plate 3 rotates, the tension spring 4 is stretched, and the pulling force of the tension spring 4 is the magnitude of the buffering resistance, but it cannot be greater than the component force of the bar gravity along the sliding direction of the support plate 1, otherwise the bar will be intercepted. When the bar decelerates and passes through the buffer plate 3, it will gently stick to the previous bar. At this time, the position of the sliding frame 2 is slightly outside the previous bar. Before the next bar is placed and rolled, the sliding frame 2 needs to be moved outward by about the distance of one bar, so that the bar can roll a shorter distance after deceleration and reduce the collision intensity. Specifically, manually grasp the handle 6 and pinch the outer end of the long rod 7 with fingers, and pinch hard, so that the long rod 7 slides outward. The long rod 7 drives the friction block 10 to slide downward through the connecting rod 8, so that the contact between the friction block 10 and the lower surface of the support plate 1 is briefly released, and the compression spring Ⅰ 9 is compressed. Without friction, the sliding frame 2 can be easily slid. After sliding to the designated position, release the hand, and the long rod 7 will reset under the drive of the compression spring Ⅰ 9, so that the friction block 10 contacts the lower surface of the support plate 1 again to ensure that the sliding frame 2 will not slide randomly. At this time, arrange and place the next bar, and finally manually rotate the knob outside the worm 14 to drive the worm wheel 13 to rotate, so as to drive the transmission shaft Ⅰ 11 to rotate, and make the clamping rod 12 rotate to the upper side to lock and limit the bar.

[0039] Similarly, when feeding the materials, the support plate 1 is adjusted to be inclined downward. If the clamping rod 12 is loosened when feeding downward, all the bars will rush down together, making it difficult to buffer. Therefore, it is also necessary to feed the materials one by one. At this time, the transmission shaft II 21 needs to slide downward in the arc-shaped chute of the limit frame 15. The downward sliding is the same as adjusting the angle of the support plate 1. In this way, the dial 22 will catch the outermost bar. Manually rotating the knob at the outer end of the transmission shaft II 21 will cause the dial 22 to rotate, so that the bars slide out one by one. After sliding out, they will pass through the buffer plate 3 again for deceleration. At this time, the direction of the buffer plate 3 needs to be adjusted. Manually move the lever 5 from one end of the chute on both sides of the sliding frame 2 to the other end, so that the tension of the tension spring 4 changes the initial angle of the buffer plate 3, so that the bars can pass through smoothly when feeding. And at this time, the position of the sliding frame 2 does not need to be adjusted for each material feeding. It only needs to be always at the outermost side of the support plate 1, because the bars will accumulate at the dial 22 under the action of gravity, and each bar for feeding starts to move from the dial 22.

[0040] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
