Description

A multi-angle chamfering machine for producing steel bars Technical Field

[0001] The embodiments disclosed herein relate to the technical field of equipment for steel bar production, and more specifically, to a multi-angle chamfering machine for steel bar production. Background Technology

[0002] In modern industrial production, steel bars, as a fundamental and crucial material, are widely used in many fields such as construction, machinery manufacturing, and the automotive industry. In the steel bar production process, the chamfering process is an extremely important step, as its quality directly affects the performance and safety of the steel bars.

[0003] Existing steel bar chamfering equipment suffers from numerous drawbacks, severely hindering improvements in production efficiency and product quality. Firstly, it is difficult to adjust the equipment conveniently according to the bar length. Different applications require vastly different steel bar lengths, ranging from tens of centimeters to several meters. However, most existing chamfering machines present extremely cumbersome adjustment processes when dealing with steel bars of varying lengths. This often necessitates manual disassembly, replacement, or repositioning of multiple components, which is not only time-consuming and labor-intensive but also prone to causing a decrease in equipment precision due to improper operation, thus affecting chamfering quality. This inflexible adjustment method leads to frequent production interruptions, failing to meet the demands of large-scale, diversified production.

[0004] On the other hand, it is inconvenient to perform multi-angle chamfering. In practical use, some steel bars need to be chamfered at different angles according to design requirements to achieve better assembly results or special mechanical properties. However, existing equipment can usually only perform single-angle chamfering operations. To achieve multi-angle chamfering, operators need to adjust the position and angle of the steel bars multiple times before processing. This not only increases the complexity and difficulty of the operation, but also makes it difficult to ensure consistent chamfering accuracy at each angle, resulting in inconsistent product quality.

[0005] As industrial manufacturing develops towards higher precision, higher efficiency, and greater diversification, the requirements for steel bar production are also increasing. The shortcomings of existing chamfering machines in adapting to bar length adjustments and multi-angle chamfering have become a bottleneck for the further development of the steel bar production industry. Developing a multi-angle chamfering machine for steel bar production that can be easily and quickly adjusted according to bar length and effortlessly achieve multi-angle chamfering is imperative. This is of significant practical importance for improving steel bar production quality, increasing production efficiency, and reducing production costs. Summary of the Invention

[0006] To overcome the above-mentioned defects, the embodiments of this disclosure provide a multi-angle chamfering machine for steel bar production, which solves the technical problem that most existing chamfering machines are extremely cumbersome in the adjustment process when facing steel bars of different lengths and can only perform chamfering operations at a single angle.

Moreover, this assembly fits tightly with other components, reducing collisions and damage to the steel bars during feeding and discharging, and lowering raw material loss. Overall, the feeding and discharging support assembly improves the efficiency and quality of the entire steel bar processing flow. Attached Figure Description

[0035] As shown in Figures 1-4, a multi-angle chamfering machine for producing steel bars according to an embodiment of this disclosure is provided, comprising:

[0036] The equipment frame 1 and a pair of high-speed motors 2 are both located inside the equipment frame 1;

[0037] Infeed / outfeed support assembly 4, which is mounted on the equipment frame 1;

[0038] A chamfering drive assembly 3 is disposed at the top of the equipment rack 1;

[0039] The chamfering drive assembly 3 includes a drive block 3-1, which is located at the output end of the high-speed motor 2. A connecting sleeve 3-2 is fitted around the drive block 3-1, and the connecting sleeve 3-2 is fixedly connected to the drive block 3-1 by bolts. A pair of chamfering blades 3-3 are provided inside the connecting sleeve 3-2. A drive screw 3-4 is provided at the top inside the equipment frame 1. The drive screw 3-4 is rotated by a motor. Both ends of the drive screw 3-4 are connected to a movable frame 3-5 by threaded engagement. A pair of slide rails 3-5 are provided at the top inside the equipment frame 1, and the movable frame 3-5 is slidably connected to the slide rails 3-5. The high-speed motor 2 is mounted on the movable frame 3-5.

[0040] In some examples, during the chamfering process of steel bar production, a chamfering drive assembly 3 is designed to meet the processing requirements of different chamfering angles. This assembly is based on a drive block 3-1 located at the output end of a high-speed motor 2. A connecting sleeve 3-2, which is fitted outside the drive block 3-1, is fixed to the drive block 3-1 by bolts. This connection method facilitates disassembly and replacement. A pair of chamfering cutters 3-3 are installed inside the connecting sleeve 3-2. Cutters of different angle specifications can be pre-installed according to the actual chamfering angle required for processing. A drive screw 3-4 located at the top of the equipment frame 1 is controlled to rotate by a motor. A movable frame 3-5 connected to the two ends of the drive screw 3-4 by threaded engagement, and a pair of slide rails 3-5 located at the top of the equipment frame 1 cooperate with each other. When the drive screw 3-4 rotates, the movable frame 3-5 can slide along the slide rails 3-5 at the top of the equipment frame 1, driving the high-speed motor 2, drive block 3-1, and connecting sleeve 3-2 mounted on the movable frame 3-5 to move together, thereby adjusting the processing position of the chamfering cutters 3-3. By replacing the connecting sleeve 3-2 with chamfering cutters 3-3 at different angles, and by adjusting the processing position using the drive screw 3-4 and the moving frame 3-5, the chamfering drive assembly 3 can flexibly adapt to the processing requirements of various chamfering angles and meet the diverse chamfering needs in steel bar production.

[0041] Through the coordinated operation of components such as drive block 3-1, connecting sleeve 3-2, bolt, chamfering cutter 3-3, drive screw 3-4, moving frame 3-5 and slide rail 3-5, the chamfering drive assembly 3 realizes the function of conveniently replacing connecting sleeve 3-2 with chamfering cutter 3-3 at different angles.

[0042] As shown in Figures 1-4, this embodiment proposes that the infeed / outfeed support assembly 4 includes a through-hole 4-1, which is formed on the surface of the equipment frame 1. A pair of telescopic cylinders 4-2 are provided at the bottom of the equipment frame 1. A connecting seat 4-3 is provided at the output end of each telescopic cylinder 4-2. A drive motor 4-4 is provided at the bottom of the connecting seat 4-3. A drive gear 4-5 is provided at the output end of the drive motor 4-4. A rotating seat 4-6 is rotatably connected to the surface of the connecting seat 4-3. A second cylinder 4-7 is installed inside the rotating seat 4-6. An external gear 4-8 is provided on the side surface of the rotating seat 4-6. The drive gear 4-5 meshes with the external gear 4-8. A support seat 4-9 is provided at the output end of the second cylinder 4-7. A pressure frame 4-10 is telescopically connected to the top of the equipment frame 1. Several springs 4-11 are fitted on the pressure frame 4-10. The equipment frame 1 is equipped with a feeding platform 4-12. Positioning seats 4-13 and discharging seats 4-14 are respectively located at both ends of the surface of the equipment frame 1. The feeding platform 4-12 is connected to the positioning seats 4-13. A crossbar 4-15 is located on one side of the equipment frame 1. A lifting cylinder 4-16 is located at the bottom of the crossbar 4-15. A pushing cylinder 4-17 is located at the output end of the lifting cylinder 4-16. A pushing frame 4-18 is located at the output end of the pushing cylinder 4-17. An adjusting cylinder 4-19 is located on one side of the positioning seat 4-13. A side baffle 4-20 is located at the output end of the adjusting cylinder 4-19. A positioning cylinder 4-21 is located on one side of the side baffle 4-20. A push plate 4-22 is located at the output end of the positioning cylinder 4-21. The pushing cylinder 4-17 and the push plate 4-22 correspond to the positions of the positioning seat 4-13.

[0043] In some examples, in the chamfering process of steel bar production, to achieve continuous feeding and adapt to the processing of steel bars of different lengths, an infeed / outfeed support assembly 4 is designed. This assembly includes a through-hole 4-1 opened on the surface of the equipment frame 1, a pair of telescopic cylinders 4-2 set at the bottom of the equipment frame 1, and a connecting seat 4-3 at the output end of the cylinders 4-2 for installing other components. The drive gear 4-5 at the output end of the drive motor 4-4 at the bottom of the connecting seat 4-3 meshes with the external gear 4-8 on the side surface of the rotating seat 4-6 rotatably connected to the surface of the connecting seat 4-3. When the drive motor 4-4 starts, it can drive the rotating seat 4-6 to rotate. The first gear installed inside the rotating seat 4-6... The two cylinders 4-7 have a support seat 4-9 at their output end that can extend or retract as needed to support the steel bar. The pressure frame 4-10 connected to the telescopic sleeve at the top of the equipment frame 1 and several springs 4-11 can press and fix the steel bar and can extend and retract to accommodate steel bars of different diameters. The feeding platform 4-12 on the equipment frame 1 is connected to the positioning seat 4-13 and is used to place the steel bar to be processed. The crossbar 4-15 on one side of the equipment frame 1 has a lifting cylinder 4-16, a pushing cylinder 4-17 and a pushing frame 4-18 at its bottom that work together to push the steel bar on the feeding platform 4-12 to the positioning seat 4-13. The adjusting cylinder 4-19, side baffle 4-20, positioning cylinder 4-21 and push plate 4-22 on one side of the positioning seat 4-13 work together. The adjusting cylinder 4-19 can adjust the position of the side baffle 4-20 to accommodate steel bars of different lengths. The positioning cylinder 4-21 drives the push plate 4-22 to accurately push the steel bar to the processing position.

[0044] Through the coordinated operation of these components, the feeding and discharging support assembly 4 achieves continuous feeding and can be flexibly adjusted according to the length of the steel bar, ensuring the efficient and stable chamfering of the steel bar.

[0045] For example, as shown in Figure 2, the surfaces of the positioning seat 4-13, the discharge seat 4-14, the discharge seat 4-14, and the pressure frame 4-10 are all arc-shaped structural surfaces.

[0046] In some examples, the curved structural surface can better fit the surface of the steel bar and can accommodate steel bars of different diameters.

[0047] In actual use: Place the steel bar to be processed on the feeding platform 4-12, which has a slight tilt angle. Adjust the cylinder 4-19 to move the side baffle 4-20. Adjust the position according to the length of the steel bar. Lower the lifting cylinder 4-16 to place the pusher 4-18 against one side of the steel bar to be processed. Then activate the pusher cylinder 4-17, which pushes the pusher 4-18 to push the steel bar into the positioning seat 4-13. At this time, the positioning cylinder 4-21 extends and pushes the steel bar into the support seat 4-9. After reaching the position, first activate the telescopic cylinder 4-2 to control the support seat. 4-9 lifts the steel bar, and the drive motor 4-4 drives the drive gear 4-5 to rotate, causing the rotating seat 4-6 to rotate 90°. After being raised, it cooperates with the pressure frame 4-10 to press the steel bar under the action of the spring 4-11. According to the required chamfer angle, the drive screw 3-4 is rotated by the motor control, which drives the moving frame 3-5, high-speed motor 2, and chamfering cutter 3-3 to move to the appropriate position. The high-speed motor 2 is started, and the chamfering cutter 3-3 performs chamfering on the steel bar. After the processing is completed, the support seat 4-9 is reset. After the next steel bar is pushed in, the chamfered steel bar is pushed into the discharge seat 4-14 and then removed.
