Description

Technical Field

[0001] This utility model is an automatic cutting device for bar processing, belonging to the field of bar processing equipment. Background Art

[0002] Automatic bar cutting is a highly automated process widely used in industries such as steel and metal processing. It is used to precisely cut long metal bars to a predetermined length. This process not only improves production efficiency but also reduces manual labor intensity and ensures the consistency and accuracy of the cutting.

[0003] Current automated bar cutting processes require clamps to hold and stably transport the bars to the bottom of the cutting machine. The cutting machine can cut the bars during its downward movement. The cut bars are then held and conveyed out by drive rollers. However, the cut bars have burrs at the ends. The cut bars are directly conveyed into the hopper for centralized stacking. Because the ends of the bars are not ground in time, the burrs at the ends will rub against the surface of the bars, causing large-area wear on the bar surface and thus reducing the quality of bar cutting.

[0004] In summary, this utility model provides an automatic cutting device for bar processing to solve the above-mentioned problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an automatic cutting equipment for bar processing, so as to solve the problem mentioned in the background art that the burrs at the ends of the cut bars cannot be eliminated in time, which leads to friction and scraping during transportation, resulting in a reduction in the quality of bar cutting.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: an automatic bar processing cutting device, comprising a base and an electric cutting machine, wherein a load-bearing plate is fixedly installed on the rear side of the top of the base, and multiple upper clamping rollers are evenly installed on the front side of the load-bearing plate from left to right via an electric rotating shaft, and multiple lower clamping rollers are evenly installed on the front side of the load-bearing plate and directly below each upper clamping roller via an electric rotating shaft, a connecting plate is fixedly installed on one side of the top of the load-bearing plate, and electric lifting rods are fixedly installed on both sides of the bottom of the connecting plate, the electric cutting machine is fixedly installed between the output ends of two electric lifting rods, and a sandblasting mechanism is fixedly installed on one side of the top of the base and between two adjacent lower clamping rollers.

[0007] Furthermore, the sandblasting mechanism includes two support plates, which are fixedly installed on one side of the top of the base. A processing box is installed between the tops of the two support plates and between the two lower clamping rollers. The processing box is cylindrical, and six sand inlet pipes are evenly penetrated through the outer cylindrical surface of the processing box. An annular pipe is connected between the opposite ends of the six sand inlet pipes and inside the processing box. The inner annular surface of the annular pipe is evenly connected to six sandblasting pipes.

[0008] Furthermore, the center of the annular tube and the center of the processing box are located on the same transverse central axis, and the sandblasting nozzles of the six sandblasting tubes all face the center of the annular tube.

[0009] Furthermore, a feed inlet is provided on one side of the processing box. The feed inlet is circular, and the center of the feed inlet and the center of the processing box are located on the same horizontal central axis.

[0010] Furthermore, a discharge port is provided on the other side of the processing box. The discharge port is circular, and the center of the discharge port and the center of the processing box are located on the same horizontal central axis.

[0011] Furthermore, the sand inlet pipe is fixedly connected to the processing box, and both sides of the bottom of the processing box are connected to sand outlet pipes.

[0012] The beneficial effects of this utility model are:

[0013] After the cut end of the bar is transported into the processing box of the sandblasting mechanism, the external sandblasting machine is started. Sandblasting shot is transported through six sand inlet pipes and a ring pipe, and the sand shot is evenly sprayed onto the cut end face of the bar through the six sandblasting pipes. This can quickly grind and eliminate the burrs generated by cutting the end of the bar. When the bars with the ground ends are stacked together, the surface will not be scratched by the burrs, which effectively improves the quality of bar cutting.

[0014] By using six sandblasting pipes to perform circumferential sandblasting on the end of the bar, the blind spots in the sanding are reduced, and the deburring effect on the end of the bar is improved. Attached Figure Description

DETAILED DESCRIPTION

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please see Figure 1-4 This utility model provides a technical solution: an automatic bar processing cutting device, including a base 1 and an electric cutting machine 7. A load-bearing plate 2 is fixedly installed on the rear side of the top of the base 1. Multiple upper clamping rollers 3 are evenly installed on the front of the load-bearing plate 2 from left to right via an electric rotating shaft. Multiple lower clamping rollers 4 are evenly installed on the front of the load-bearing plate 2 and directly below each upper clamping roller 3 via an electric rotating shaft. A connecting plate 5 is fixedly installed on one side of the top of the load-bearing plate 2. Electric lifting rods 6 are fixedly installed on both sides of the bottom of the connecting plate 5. The electric cutting machine 7 is fixedly installed between the output ends of the two electric lifting rods 6. Both electric lifting rods 6 are connected to an external power supply and are equipped with the same power control switch. The upper lifting rods 6 are fixedly installed on one side of the top of the base 1 and located between two adjacent lower lifting rods 6. A sandblasting mechanism 8 is fixedly installed between the clamping rollers 4. The electric cutting machine 7 consists of a motor, a cutting blade, a protective cover, a mounting base, and an adjustment device. The motor provides power to the entire electric cutting machine 7 and drives the cutting blade to rotate. The cutting blade is used for the actual cutting operation. Different cutting blades are selected according to different materials. The protective cover is used to protect the operator from injury by flying debris. The mounting base is used to support the entire electric cutting machine 7 and maintain stability. The adjustment device is used to adjust the cutting depth and angle. The electric cutting machine 7 is located directly above the path of the upper clamping roller 3 and the lower clamping roller 4 that clamps and conveys the bar. The electric rotating shafts on the upper clamping roller 3 and the lower clamping roller 4 rotate in opposite directions. The upper clamping roller 3 rotates counterclockwise, and the lower clamping roller 4 rotates clockwise, so that the clamped bar can be conveyed from left to right.

[0023] Please see Figure 2-4The sandblasting mechanism 8 includes two support plates 81, which are fixedly installed on one side of the top of the base 1. A processing box 82 is installed between the tops of the two support plates 81 and between the two lower clamping rollers 4. The processing box 82 is cylindrical, and six sand inlet pipes 83 are evenly distributed through the outer cylindrical surface of the processing box 82. The sand inlet pipes 83 are connected to the sand outlet of the external sandblasting machine. An annular pipe 84 is connected between the opposite ends of the six sand inlet pipes 83 and inside the processing box 82. Six sandblasting pipes 85 are evenly distributed on the inner annular surface of the annular pipe 84. The center of the annular pipe 84 and the center of the processing box 82 are located on the same transverse central axis. The sandblasting nozzles of 5 all face the center of the annular pipe 84. A feed inlet 86 is provided on one side of the processing box 82. The feed inlet 86 is circular, and the center of the feed inlet 86 is on the same horizontal central axis as the center of the processing box 82. A discharge outlet 87 is provided on the other side of the processing box 82. The discharge outlet 87 is circular, and the center of the discharge outlet 87 is on the same horizontal central axis as the center of the processing box 82. The sand inlet pipe 83 is fixedly connected to the processing box 82. Both sides of the bottom of the processing box 82 are connected to the sand discharge pipe 88. The upper clamping roller 3 and the lower clamping roller 4 can clamp and convey the bar, and the center of the bar is on the same horizontal central axis as the center of the feed inlet 86.

[0024] Detailed implementation: By starting the electric rotating shafts on the upper clamping roller 3 and the lower clamping roller 4, the upper clamping roller 3 rotates counterclockwise and the lower clamping roller 4 rotates clockwise. This allows the upper clamping roller 3 and the lower clamping roller 4 to stably clamp the bar while conveying it from left to right. When the bar to be cut is moved to the position directly below the electric cutting machine 7, the electric cutting machine 7 and the two electric lifting rods 6 are started. The two electric lifting rods 6 drive the electric cutting machine 7 to move downward. The cutting blade inside the electric cutting machine 7 moves downward and rotates at high speed, thereby enabling rapid cutting of the bar below.

[0025] After cutting, the electric rotating shafts on the upper clamping roller 3 and lower clamping roller 4 are restarted to drive the bar material to be conveyed. The end of the bar material is conveyed from the feed port 86 of the processing box 82 inside the sandblasting mechanism 8 into the processing box 82, so that the end of the bar material is located at the center of the annular tube 84. The external sandblasting machine is started, and sandblasting shot is conveyed through the six sand inlet pipes 83 and the annular tube 84. The sand shot is evenly sprayed onto the cut end face of the bar material through the six sandblasting pipes 85, so that the burrs generated by cutting can be quickly ground and eliminated. After sandblasting and grinding, the bar material can be conveyed out from the discharge port 87 with the rotation of the upper clamping roller 3 and lower clamping roller 4, which is convenient for the next step of packaging and transportation. When the bar materials with ground ends are stacked together, the surface will not be scratched by burrs, which effectively improves the quality of bar material cutting and processing.

[0026] By using six sandblasting pipes (85mm diameter) to perform circumferential sandblasting on the end of the bar, the blind spots in the sandblasting are reduced, and the deburring effect on the end of the bar is improved.

[0027] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
