Description

Technical Field

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

[0002] Bar forming in steel rolling mills is a crucial step in steel production, primarily used to process steel billets into bars of various specifications through multiple rolling processes. Bars are widely used in construction, machinery, automotive, and other fields.

[0003] The bar beveling device in a steel rolling production line is a piece of equipment used to improve the edge shape of the bar. Its main function is to bevele both ends of the rolled steel bar to avoid the right angle at both ends of the rolled steel bar from causing scratches to the user.

[0004] In the process of realizing this utility model, the inventors discovered the following problems with the existing technology: 1. When using some existing ordinary chamfering devices, they can usually only perform chamfering operations on bars of a specific diameter, with a narrow range of applications, making it difficult to flexibly meet diverse production needs; 2. When using a chamfering device to chamfer bars, dust will inevitably be generated. This dust will spread freely and quickly diffuse into the surrounding air, causing air pollution. When operators are in the working environment without any protection or with insufficient protection, they are very likely to inhale this dust, which will affect their health. Utility Model Content

Then the dust is sent into the dust collection bag to prevent the dust from spreading into the surrounding air and causing air pollution. This also prevents the dust from being inhaled by the operator and improves the safety of the device during use. Attached Figure Description

The first slider 305 and the first geared motor 303 form a transmission mechanism through the threaded rod 304. At the same time, the second mounting frame 309 and the second geared motor 307 form a rotation mechanism through the U-shaped frame 308.

The third geared motor 3011, the bidirectional screw 3012, the second slider 3013, the connecting rod 3014, and the cutter 3015 can move left and right. The position of the cutter 3015 can be adjusted as needed. A distance sensor is provided on one side of the U-shaped frame 308. When the second geared motor 307 is started, it can drive the U-shaped frame 308, the second mounting frame 309, the third slider 3010, the third geared motor 3011, the bidirectional screw 3012, the second slider 3013, the connecting rod 3014, and the cutter 3015 to rotate. The two cutters 3015 can be used to chamfer the bar.

[0030] In this embodiment, as Figure 4 As shown, the front end of the second slider 3013 has a circular hole, and the third slide rod 3010 is slidably installed in the circular hole at the front end of the second slider 3013. The second slider 3013, the connecting rod 3014, and the cutter 3015 are symmetrically distributed about the vertical center line of the third slide rod 3010. At the same time, the second slider 3013 and the third reduction motor 3011 form a transmission mechanism through the bidirectional screw 3012. When the third reduction motor 3011 is started, the distance between the two second sliders 3013 can be adjusted through the bidirectional screw 3012, thereby adjusting the distance between the two cutters 3015, which can be used to chamfer bars of different diameters.

[0031] In this embodiment, as Figure 5 As shown, the dust hoods 403 are symmetrically distributed about the vertical center line of the dustproof pipe 402, and the air inlet of the centrifugal fan 405 is connected to one end of the L-shaped mounting plate 401. When the centrifugal fan 405 is started, the dust generated when the bar is beveling can be sucked up through the dust hoods 403 and the three-way pipe 404, so as to prevent the dust from drifting into the air and causing air pollution.

[0032] In this embodiment, as Figure 1 and Figure 2 As shown, the chamfering assembly 3 and the dust collection assembly 4 are symmetrically distributed about the vertical center line of the base plate 1; by using two sets of chamfering assemblies 3 and dust collection assembly 4, both ends of the rod can be chamfered at the same time, improving the working efficiency when chamfering the rod.

[0033] The usage and advantages of this utility model: The working process of this bar beveling device for steel rolling production lines is as follows:

[0034] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, firstly, the third reduction motor 3011 is started. The distance between the two cutters 3015 is adjusted through the bidirectional screw 3012, the second slider 3013, and the connecting rod 3014. According to the diameter of the bar, the two cutters 3015 are adjusted to a suitable distance. Then, the bar is placed in the grooves of several first arc-shaped clamping blocks 206. Next, the first electric push rod 202 is started, which moves the support plate 204, the sliding tube 205, and the first arc-shaped clamping blocks 206 to move the bar to a suitable height. Then, the first electric push rod 202 is stopped and the second electric push rod 207 is started, which moves the second arc-shaped clamping block 208 and the first sliding rod 209 downward. The second arc-shaped clamping block 208 cooperates with the first arc-shaped clamping block 206 to clamp the bar. Then, the second electric push rod 207 is stopped and the first reduction motor 303 of the two chamfering components 3 is started. The threaded rod 304 drives the first slider 305, the fixing plate 306, the second reduction motor 307, and the U-shaped frame. 308, 309, 3010, 3011, 3012, 3013, 3014, and 3015 of the second mounting frame, third slide bar, third geared motor, bidirectional screw, second slider, connecting rod, and cutter 3015 move together, bringing the cutter 3015 closer to both ends of the bar. Distance sensors on the U-shaped frame 308 detect the distance. When the cutter 3015 approaches the bar, the second geared motor 307 and centrifugal fan 405 are activated. The second geared motor 307 drives the U-shaped frame 308... The second mounting frame 309, the third slide bar 3010, the third geared motor 3011, the bidirectional screw 3012, the second slider 3013, the connecting rod 3014, and the cutter 3015 rotate to chamfer the bar. The centrifugal fan 405 sucks up the dust generated during the chamfering of the bar through the dust suction hood 403 and the three-way pipe 404. After the chamfering is completed, the first geared motor 303 and the second electric push rod 207 drive the cutter 3015 and the second arc-shaped clamp 208 to reset.
