Description

Technical Field

[0001] This utility model relates to the field of stainless steel pipe processing technology, specifically a wear-resistant and long-lasting round steel billet feeding device. Background Technology

[0002] Round steel billets are raw materials for many parts processing. Before processing, they generally undergo heat treatment in a heating furnace. Large processing enterprises typically use automatic feeding devices to automatically transport the round steel billets stored on the rack into the heating furnace. Existing automatic feeding devices generally use feeding racks welded and assembled from through-section steel (such as Q235). Figure 4 , Figure 5 As shown, the following problems exist when workpiece 1 is rolled and conveyed on the platform: 1. High wear problem: Sliding friction occurs between the steel billet and the steel rail 7. The surface hardness of ordinary steel is only 150-200HB, resulting in an average monthly wear of 3-5mm on the steel rail 7. 2. Risk of jamming: Grooves caused by wear on the surface of the steel rail 7 will increase rolling resistance, which may lead to problems such as steel billet accumulation and deviation in severe cases; 3. When replacing or repairing the existing material rack structure, it is usually necessary to replace the entire frame or repair it by welding. A single repair takes ≥8 hours and the annual maintenance cost exceeds 200,000 yuan. Summary of the Invention

[0003] The purpose of this invention is to solve the problems existing in the prior art and provide a wear-resistant and long-lasting round steel billet feeding device.

[0004] The specific solution of this utility model is as follows: a wear-resistant and long-lasting round steel billet feeding device, including a first inclined platform and a second inclined platform. The second inclined platform is located above the first inclined platform. A lifting mechanism is provided between the first and second inclined platforms. The lifting mechanism is used to lift the round steel billet at the bottom of the first inclined platform to the second inclined platform. The bottom end of the second inclined platform is provided with a conveyor roller and a turning device. The turning device is used to turn the round steel billet on the second inclined platform onto the conveyor roller. The first inclined platform includes a base. The top of the base is provided with several parallel and inclined support beams. A wear-resistant round bar is placed on the top of each support beam. The wear-resistant round bar is arranged parallel to the support beam. Limiting members are provided on both sides of the wear-resistant round bar on each support beam. The round steel billet is perpendicular to the wear-resistant round bar. The second inclined platform has the same structure as the first inclined platform.

[0005] Furthermore, a stop block is installed at each end of the wear-resistant round bar on the support beam, and the stop block is used to restrict the movement of the wear-resistant round bar.

[0006] Furthermore, the limiting component is made of angle steel, which is welded to the support beam.

[0007] Furthermore, the supporting beam is made of I-beams.

[0008] Furthermore, the turning device includes a turning arm, which is disposed between the conveying rollers of the conveying roller track. One end of the turning arm is rotatably connected to the base of the second inclined platform, and a cylinder is connected to the middle of the turning arm. The piston rod of the cylinder is rotatably connected to the turning arm, and the cylinder body is rotatably connected to the fixed frame of the conveying roller track.

[0009] The present invention has the following advantages: 1. Using wear-resistant round bars as the slide of round steel billets reduces the contact area and friction compared to shaped steel tracks; 2. After the contact surface between the wear-resistant round bars and the workpiece is worn, the unworn part can be used as a new slide by rotating the wear-resistant round bars at a certain angle, thereby greatly improving the service life.

[0011] See Figure 1-5 This embodiment is a wear-resistant, long-lasting round steel billet feeding device, including a first inclined platform 2 and a second inclined platform 3. The second inclined platform 3 is located above the first inclined platform 2. A lifting mechanism 4 is provided between the first inclined platform 2 and the second inclined platform 3. The lifting mechanism 4 is used to lift the round steel billet at the bottom of the first inclined platform 2 onto the second inclined platform 3. The bottom end of the second inclined platform 3 is provided with a conveying roller 6 and a turning device. The turning device is used to turn the round steel billet on the second inclined platform 3 onto the conveying roller 6. The first inclined platform 2 includes a base 22. The top of the base 22 is provided with several parallel and inclined support beams 21. A wear-resistant round bar 24 is placed on the top of each support beam 21. The wear-resistant round bar 24 is arranged parallel to the support beam 21. Limiting members 23 are provided on both sides of the wear-resistant round bar 24 on each support beam 21. The round steel billet is perpendicular to the wear-resistant round bar 24. The second inclined platform 3 has the same structure as the first inclined platform 2.

[0012] Furthermore, a stop block 8 is installed at each end of the wear-resistant round bar 24 on the support beam 21. The stop block 8 is used to restrict the movement of the wear-resistant round bar 24.

[0013] Furthermore, the limiting member 23 is made of angle steel, which is welded to the support beam 21.

[0014] Furthermore, the support beam 21 is made of I-beams.

[0015] Furthermore, the turning device includes a turning arm, which is disposed between the conveying rollers of the conveying roller table 6. One end of the turning arm is rotatably connected to the base 22 of the second inclined platform 3. A cylinder is connected to the middle of the turning arm. The piston rod of the cylinder is rotatably connected to the turning arm, and the cylinder body is rotatably connected to the fixed frame of the conveying roller table 6.

[0016] The lifting mechanism 4 described in this embodiment adopts a stepping ladder lifting mechanism 4, the structure of which belongs to the prior art. For example, patent document CN109132382A discloses a high-efficiency conveying mechanism for large shaft workpieces.

[0017] In operation, the round steel billets are stacked and stored on the first inclined frame 2. The round steel billets roll down along the wear-resistant round bars 24 of the first inclined frame 2 and are lifted to the second inclined frame 3 by the lifting mechanism 4. Thus, a certain amount of workpieces 1 are stored on both the first inclined frame 2 and the second inclined frame 3. When it is necessary to feed material into the heating furnace, the turning mechanism 5 is activated. The turning arm is driven to rotate by the cylinder. The workpiece 1 on the turning arm near the end of the conveying roller 6 is placed on the conveying roller. The workpiece 1 is sent into the heating furnace by the conveying roller. After it is completely sent in, the turning mechanism 5 waits for the next feeding command and then turns the next workpiece 1 onto the conveying roller. Each time the turning mechanism 5 sends away a workpiece 1, the workpieces 1 on the first inclined frame 2 and the second inclined frame 3 will automatically move down one material position under the action of gravity.

[0018] When the contact surface between the wear-resistant round bar 24 of the first inclined platform 2 or the second inclined platform 3 and the workpiece 1 becomes worn and needs to be replaced, during the maintenance period, the wear-resistant round bar 24 can be rotated at a certain angle so that the worn part avoids the workpiece 1, while the other parts are rotated to the contact surface with the workpiece 1 to form a new slide. This can greatly improve the service life of the wear-resistant round bar 24. When the wear-resistant round bar 24 is worn at multiple angles, it can be directly replaced, while the support beam 21 and the base 22 below do not need to be replaced. Therefore, this utility model greatly reduces the annual maintenance and replacement cost.

[0019] The wear-resistant round bar 24 of this utility model is hardened by quenching, with a hardening depth of 5-6mm, which further reduces the frictional resistance between it and the workpiece 1.
