Description

Technical Field

[0001] This utility model relates to the field of steel bar processing technology, specifically a steel bar chamfering device. Background Technology

[0002] In practical applications, steel bars are used in a variety of fields: the machinery manufacturing industry often uses them to process key components such as shafts, gears, and bolts; in the construction and steel structure industry, they can be used as supporting components or embedded parts; in high-end manufacturing fields such as automobiles, ships, and aerospace, special alloy steel bars are selected to meet stringent performance requirements such as wear resistance, high temperature resistance, and corrosion resistance; in addition, steel bars also play an important role in the production of hardware tools, medical devices, and daily necessities, serving as an important intermediate form connecting raw materials and end products.

[0003] The simplest way to automate the chamfering of steel bars in the existing technology is through a combination of vibratory feeder feeding, fixed fixture, and single-axis chamfering cutter. The vibratory feeder arranges the disordered steel bars in a uniform direction and automatically conveys them to the fixed fixture with a V-groove via a straight rail. After triggering the sensor, the fixture cylinder presses down to clamp the steel bar. Then, the single-axis chamfering cutter, driven by a servo motor, moves towards the end of the steel bar at a preset angle and depth. After chamfering one end, the fixture is released, the cylinder pushes the steel bar to rotate 180 degrees and clamps it again, and the chamfering cutter repeats the action to complete the processing of the other end. After processing, the fixture is released, and the steel bar slides into the finished product box by gravity.

[0004] Vibratory feeder feeding relies on the steel bar's own posture adjustment and track guidance. When the steel bar surface has oil stains, rust, or slight deviations in specifications, it is prone to jamming and blockage, requiring frequent manual shutdowns for cleaning, interrupting the processing flow, and making it impossible to achieve efficient automation of steel bar chamfering. To address the above problems, a steel bar chamfering device is proposed. Utility Model Content

[0007] By adopting the above technical solution, the gear assembly contains three gears that mesh with each other, the pulley assembly contains two pulleys and a belt, and the front end of the pulley assembly is provided with a housing to protect the pulley assembly.

[0011] By adopting the above technical solution, the fixing block limits the rear end of the slide bar, preventing excessive movement of the slide bar.

[0012] As a further description of the above technical solution: a fan is fixedly connected to the rear end of one side of the top of the base plate, and a collection box is fixedly connected through the input end of the fan.

[0013] By adopting the above technical solution, a filter screen is installed at the input end of the exhaust fan to prevent dust from entering and avoid damage to the exhaust fan.

[0014] As a further description of the above technical solution: a flexible hose is connected through and fixedly to the top of the collection box, and one end of the flexible hose is connected through and fixedly to the dust collection hood.

[0015] By adopting the above technical solution, the dust hood delivers the adsorbed dust to the collection box through a hose.

[0016] As a further description of the above technical solution: a guide frame is fixedly connected to the other side of the top of the base plate.

[0017] By adopting the above technical solution, the guide frame can guide the chamfered steel bars.

[0018] As a further description of the above technical solution: a control panel is fixedly connected to the front end of the feeding box, and a baffle is fixedly connected to the top of the middle of the inner wall of the feeding box.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model provides a steel bar chamfering device. Firstly, through the linkage design of gear and pulley sets, the feeding roller and the chamfering roller not only rotate in the same direction but also rotate synchronously. While the feeding roller conveys new steel bars, the chamfering roller can simultaneously rotate the processed steel bars to the unloading position and rotate the next steel bar to be processed to the top processing position, realizing the synchronous connection of feeding, processing, and unloading, which greatly increases the processing quantity per unit time. The combination of double fixing ensures that the steel bars are always in a stable state during the chamfering process, effectively avoiding quality problems such as chamfering angle deviation and excessive edge burrs caused by loose fixing, and avoiding the time loss of manual handling and positioning. The continuous rotation of the feeding roller can stably achieve single-bar orderly feeding, preventing multiple steel bars from stacking and blocking, and ensuring a stable feeding rhythm.

[0023] This utility model provides a steel bar chamfering device that uses negative pressure adsorption principle. The dust suction port of the dust collection hood strongly adsorbs iron filings, preventing them from splashing in the processing area at the source and avoiding them from falling onto other parts of the equipment or the operating area. This keeps the processing environment clean. If iron filings splash and accumulate on the transmission or processing components of the equipment, they can easily cause wear, jamming, or a decrease in processing accuracy. This collection method protects the normal operation of key components of the equipment and extends the service life of the equipment. Attached Figure Description

[0031] Working principle: First, the steel bar is placed in the feeding box 2. Guided by the inlet guide plate 3, the steel bar enters the feeding roller 4. The external motor drives the feeding roller 4 to rotate, causing the steel bar to fall onto the baffle 5. Then, guided by the outlet guide plate 6, the steel bar reaches the chamfering roller 10 and falls into the inclined groove of the chamfering roller 10. During the rotation of the feeding roller 4, the gear set 7 and the pulley set 8 drive the chamfering roller 10 to rotate in the same direction as the feeding roller 4, and they rotate synchronously. The rotation of the chamfering roller 10 rotates the steel bar in the groove to the top. Then, driven by the hydraulic cylinder 12, the fixing plate 13 moves downward to initially fix the steel bar. The pressure of the spring 16 is released, and the pressure block 17 fixes the steel bar a second time. Finally, the moving component 18... In conjunction with the chamfering assembly 19, the steel bar is chamfered. The rotation of the feeding roller 4 transports the individual steel bar to the chamfering roller 10, allowing the steel bar to reach the processing position on the chamfering roller 10. The rotation of the feeding roller 4 drives the chamfering roller 10 to rotate synchronously, causing the processed steel bar to fall onto the guide frame 25. This causes the previous steel bar to be processed on the chamfering roller 10 to rotate to the top. Then, the position of the steel bar is fixed by the fixing assembly, thereby realizing continuous processing of the steel bar. During the processing, the exhaust fan 27 extracts the air pressure in the collection box 29, creating a negative pressure state inside the collection box 29. The air is then guided through the hose 28, making the suction port 22 in the dust suction hood 21 have suction properties to collect iron filings, thereby preventing iron filings from splashing during the chamfering process and enabling the collection of iron filings generated during the chamfering process.
