[0002] At present, since the overall height of some thread rolling machines and the height of the discharge pipe relative to the ground are relatively high, if the bolts after thread rolling roll directly from the thread rolling machine into the collecting device, they are easily damaged due to the large impact force when falling. Therefore, a protective device with buffering capacity is used to buffer the falling bolts, so that the bolts will not be damaged by the impact force when falling into the main collecting device.

[0003] The existing protective device mainly uses a buffer pad to buffer the falling bolt, and when the bolt falls on the buffer pad, the buffer pad is automatically tilted due to the weight of the bolt, and the bolt slides off the buffer pad when passing through the tilted buffer pad. For example, a protective device for bolt thread rolling processing disclosed in Chinese patent publication No. CN217412296U, but when a lighter bolt falls on the buffer pad, the tilt angle of the buffer pad changes less due to its lighter weight, so that the bolt cannot slide off the buffer pad quickly.

[0027] Embodiment 1:

[0028] Reference Figure 1-7A protective device for bolt thread rolling processing, comprising a bottom plate 1, a first U-shaped plate 2 is fixedly connected to the upper surface of the bottom plate 1, a column 3 is fixedly connected to the upper surface of the first U-shaped plate 2, a discharge pipe 4 is fixedly connected to the upper surface of the column 3, the discharge pipe 4 is supported by the column 3, and the discharge pipe 4 is obliquely arranged on the first U-shaped plate 2, a first strip hole 5 is opened on both the front and rear sides of the first U-shaped plate 2, the angle between the first strip hole 5 and the horizontal plane is 30°, and an elastic bracket 6 is fixedly connected to both the front and rear sides of the first U-shaped plate 2, and the surface of the elastic bracket 6 contacts the inner wall of the first strip hole 5 A second strip hole 7 is provided on both the front and rear sides of the first U-shaped plate 2, and the second strip hole 7 is perpendicular to the horizontal plane. A threaded column 8 is fitted on the inner wall of the second strip hole 7, and a limiting ring 9 is fixedly connected to the surface of the threaded column 8. A first rubber ring 10 is fitted on the back of the limiting ring 9, the front of the first U-shaped plate 2, and the surface of the threaded column 8. A threaded cylinder 11 is threadedly connected to the surface of the threaded cylinder 8, and a rotating block 12 is fixedly connected to the surface of the threaded cylinder 11. A second rubber ring 13 is fitted on the front of the rotating block 12, the back of the first U-shaped plate 2, and the surface of the threaded cylinder 11. When the user rotates the rotating block 12, the second rubber ring 13 is fitted on the front of the rotating block 12, and the second rubber ring 13 is fitted on the surface of the threaded cylinder 11. When the block 12 is turned, the threaded column 8 and the threaded barrel 11 cooperate to make the rotating block 12 move forward or backward on the threaded column 8, and make the first rubber ring 10 and the second rubber ring 13 clamp or loosen the first U-shaped plate 2. When the first rubber ring 10 and the second rubber ring 13 clamp the first U-shaped plate 2, the friction between the first rubber ring 10 and the second rubber ring 13 and the first U-shaped plate 2 can prevent the threaded column 8 from moving in the second strip hole 7. When the first rubber ring 10 and the second rubber ring 13 loosen the first U-shaped plate 2, the threaded column 8 can slide in the second strip hole 7, and the surface of the threaded column 8 is close to the first U-shaped plate 2. A connecting ring 14 is provided, and a buffer plate 15 is fixedly connected to the right side of the connecting ring 14. The left side of the buffer plate 15 is connected to the threaded column 8 through the connecting ring 14, and the buffer plate 15 can rotate around the threaded column 8. The upper surface of the elastic bracket 6 and the front and rear sides of the inner wall of the first U-shaped plate 2 are in contact with the surface of the buffer plate 15. A buffer pad 16 is bonded to the upper surface of the buffer plate 15, and the bolts falling on the buffer plate 15 are buffered by the buffer pad 16. A drop opening 17 is opened on the upper surface of the first U-shaped plate 2, and the bolts in the discharge pipe 4 fall onto the buffer plate 15 through the drop opening 17.

[0029] The elastic bracket 6 includes a cylinder 61, the upper surface of the cylinder 61 contacts the bottom of the buffer plate 15, the surface of the cylinder 61 is fixedly connected to a first connecting block 62, the left side of the first connecting block 62 is fixedly connected to a spring 63, the left side of the spring 63 and the front and rear sides of the first U-shaped plate 2 are fixedly connected to a second connecting block 64, when the bolt falls onto the buffer plate 15, the gravity of the bolt causes the cylinder 61 to slide in the first strip hole 5 and compress the spring 63, when the bolt slides off the buffer plate 15, the elastic force of the spring 63 causes the buffer plate 15 to return to its initial position.

[0030] Embodiment 2:

[0031] Reference Figure 1-8 A support block 18 is fixedly connected to the front of the first U-shaped plate 2, and a second U-shaped plate 19 is fixedly connected to the front of the support block 18. A slide groove 20 is provided on the front of the threaded column 8. A limiting column 21 is fitted on the upper surface of the bottom plate 1, the inner wall of the slide groove 20, the inner wall of the second U-shaped plate 19 and the front of the support block 18. When the limiting column 21 is inserted into the second U-shaped plate 19, the threaded column 8 cannot rotate through the cooperation of the limiting column 21 and the slide groove 20, so that when the user rotates the rotating block 12, the threaded column 8 will not rotate with the rotating block 12. At the same time, when the limiting column 21 is separated from the second U-shaped plate 19, the threaded column 8 can be taken out of the second strip hole 7 by unscrewing the threaded tube 11 from the threaded column 8.

[0032] Embodiment three:

[0033] Reference Figure 1-9 A magnetic ring 22 is fixedly connected to the surface of the threaded column 8, and a connecting bracket 23 is attached to the front of the magnetic ring 22.

[0034] The connecting bracket 23 includes a first iron ring 231, a connecting column 232 is fixedly connected to the surface of the first iron ring 231, and a second iron ring 233 is fixedly connected to the side of the connecting column 232 away from the first iron ring 231. The back of the first iron ring 231 and the back of the second iron ring 233 are both in contact with the front of the magnetic ring 22, and the inner wall of the first iron ring 231 and the inner wall of the second iron ring 233 are both in contact with the surface of the threaded column 8. When the first iron ring 231 and the second iron ring 233 on the connecting bracket 23 are both sleeved on the threaded column 8, the connecting bracket 23 can be fixed on the threaded column 8 through the suction force of the magnetic ring 22 on the first iron ring 231 and the second iron ring 233, and the three threaded columns 8 can be moved synchronously through the connecting bracket 23, and then through the cooperation of the magnetic ring 22 and the connecting bracket 23, the user can adjust the inclination angle of the three buffer plates 15 at one time, so that the user can adjust the inclination angle of the three buffer plates 15 more conveniently.

[0035] In the utility model, when the user uses the protective device, the protective device is first placed at the designated position. When the bolt after thread rolling is discharged from the thread rolling machine, the bolt falls into the discharge pipe 4, and the bolt falls on the buffer pad 16 through the cooperation of the inclined discharge pipe 4 and the drop port 17. Then, when the bolt falls on the buffer plate 15, the buffer plate 15 is tilted by the gravity of the bolt, and the bolt falls on the next buffer pad 16 through the inclined buffer plate 15. When the bolt slides off the buffer plate 15, the buffer plate 15 is returned to the initial position by the elastic force of the spring 63. When the user needs to adjust the initial tilt angle of the buffer plate 15, first adjust the buffer plate 15 by the spring 63. By rotating the rotating block 12, the first rubber ring 10 and the second rubber ring 13 are loosened with the cooperation of the threaded tube 11 and the threaded column 8, and then, by adjusting the position of the threaded column 8 in the second strip hole 7, the initial inclination angle of the buffer plate 15 is changed. When the adjustment is completed, by rotating the rotating block 12, the first rubber ring 10 and the second rubber ring 13 are clamped with the cooperation of the threaded tube 11 and the threaded column 8. At this time, through the friction between the first rubber ring 10 and the second rubber ring 13 and the first U-shaped plate 2, the threaded column 8 cannot move in the second strip hole 7, and the initial inclination angle of the buffer plate 15 cannot be changed.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
