Description

Technical Field

[0001] This utility model relates to the field of bar cutting technology, specifically a cemented carbide bar cutting device. Background Technology

[0002] After extrusion molding, the bars need to be cut to a fixed length according to application requirements. This step is the core process to ensure the consistency of product size and specifications and the efficiency of mass production. At present, the industry generally uses manual cutting to process the extruded alloy bars to a fixed length. The typical operation process is as follows: after the extruder performs a certain extrusion stroke, it stops working and the operator uses a cutting device to manually measure and cut the extruded bar. After the cutting is completed, the extruder is restarted to perform the next extrusion stroke, and then it stops again to wait for the next cutting, and so on.

[0003] The above operation is an intermittent operation mode of "extrusion-pause-cutting". However, the manual control of the cutting size inevitably introduces a large error, resulting in inconsistent lengths of finished bars. More importantly, the intermittent cutting process causes differences in the density of the bars in different extrusion sections. After sintering, the products will have quality problems such as uneven density and inconsistent size. The entire production process requires frequent start-ups and shutdowns of equipment and waiting for manual operation, which seriously disrupts the continuity of production and makes the work inefficient.

Detailed Implementation

[0018] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0020] like Figures 1-6 As shown, this application provides a cemented carbide bar cutting device, including: a bottom support 1; a conveying component disposed above the bottom support 1 for conveying the bar; an adjusting component disposed between the bottom support 1 and the conveying component for adjusting the height of the conveying component; a cutting component disposed on the bottom support 1 and above the conveying component, the bottom end of the cutting component being provided with a cutter 22, the cutting component being used to cut the bar above the conveying component; and a protective component disposed on the cutting component for protecting the cutter 22.

[0021] The height of the conveying component can be adjusted by adjusting the components, thus adapting to the discharge height of different bar extruders. The conveying component transports the extruded bars, and the cutting component drives the cutter 22 to cut the extruded bars. When not cutting, the protective component protects the cutter 22, preventing damage to the cutter 22 or injury to operators from contact with the cutter 22. It can continuously cut the extruded bars, reducing the inconsistency in the length of the finished bars caused by human cutting errors, and preventing differences in the density of the bars in different extrusion sections due to intermittent cutting processes, thus improving the quality of the cut bars. It also eliminates the need for frequent start-ups and shutdowns of the equipment, improving work efficiency.

[0022] Specifically, such as Figure 1 As shown, the conveying component includes a conveyor belt 2, with conveyor supports 3 at both ends of the conveyor belt 2, and multiple sets of positioning rods 12 arranged above the conveyor belt 2; the positioning rods 12 are arranged at intervals.

[0023] Specifically, such as Figure 1 As shown, the adjusting component includes a rotating drum 8, which is rotatably mounted on the top of the bottom support 1. A screw 9 is fixed at the corresponding position of the rotating drum 8 on the conveying support 3. The screw 9 is screwed to the rotating drum 8. Multiple sets of guide sleeves 4 are connected between the bottom support 1 and the conveying support 3. The guide sleeves 4 are located on both sides of the rotating drum 8. A first gear 10 is provided at the bottom of the rotating drum 8. A second gear 11 is rotatably mounted on the bottom support 1. The second gear 11 meshes with the first gear 10. A handle 1101 is provided at the top of the second gear 11.

[0024] Rotating the second gear 11 via the lever 1101 can drive the rotating drum 8 to rotate via the first gear 10. At this time, the rotating drum 8, in conjunction with the screw 9, can drive the conveyor support 3 at one end of the conveyor belt 2 to rise and fall. The guide sleeve 4 guides the conveyor support 3, which can not only adjust the overall height of the conveyor belt 2, but also adjust the tilt angle of the conveyor belt 2, thereby adjusting the subsequent cutting angle.

[0025] By setting multiple sets of positioning rods 12 at the top of the conveyor belt 2, the multiple sets of positioning rods 12 are spaced apart. The spacing along the conveying direction of the conveyor belt 2 facilitates the cutting of the bar stock, while the positioning rods 12 spaced apart along the radial direction of the conveyor belt 2 allow the device to cut multiple sets of bar stock simultaneously.

[0026] Specifically, such as Figure 2 As shown, the cutting component includes a cutting bracket 13, which is fixed to the top of the bottom bracket 1. A slide rail seat 15 is fixed on the cutting bracket 13. An electric slide rail 14 is provided on the slide rail seat 15. A moving plate 24 is provided on the electric slide rail 14. A cutting cylinder 16 is provided on the moving plate 24. A cutter 22 is fixed at the output end of the cutting cylinder 16.

[0027] The cutting cylinder 16 drives the cutter 22 to move downward to cut a group of bars. The electric slide rail 14 drives the cutting cylinder 16 to move laterally, so that the cutter 22 can cut along different groups of positioning rods 12 in an alternating manner, thereby cutting multiple groups of bars.

[0028] Specifically, such as Figures 3-6 As shown, the protective components include a rotating shaft 19, which is rotatably mounted on both sides of the fixed end of the cutting cylinder 16. A fixing plate 18 is connected to the end of the rotating shaft 19 away from the cutting cylinder 16, and a protective plate 17 is connected to the bottom of the fixing plate 18. Protective blocks 21 are fixed to both sides of the cutting cylinder 16, and the rotating shaft 19 passes through the protective blocks 21. A torsion spring 20 is provided between the protective blocks 21 and the rotating shaft 19, which drives the rotating shaft 19 and the protective plate 17 to rotate away from the cutter 22. A retaining member is also provided between the protective blocks 21 and the rotating shaft 19 to drive the rotating shaft 19 and the protective plate 17 to rotate away from the cutter 22. Plate 17 rotates toward cutter 22; the supporting member includes an adjustment groove 28, which is opened in the protective block 21. A third gear 29 is provided at the position of the rotating shaft 19 corresponding to the adjustment groove 28. A movable cavity 25 is opened in the protective block 21, which is connected to the adjustment groove 28. A movable block 26 is slidably arranged in the movable cavity 25. The movable block 26 has an "L" shaped structure. A tooth 27 is provided on one side of the movable block 26 corresponding to the third gear 29. The tooth 27 meshes with the third gear 29. A stop block 23 is fixed at the top of the cutter 22 at the position corresponding to the movable block 26.

[0029] The cutting cylinder 16 drives the cutter 22 to move downwards. At this time, the cutter 22 drives the abutment block 23 to move downwards. The torsion spring 20 drives the rotating shaft 19 and the protective plate 17 to rotate away from the cutter 22, thereby moving the cutter 22 away from the protective plate 17 and not affecting the cutting of the bar by the protective plate 17. When the rotating shaft 19 rotates, it drives the movable block 26 to move downwards through the cooperation of the third gear 29 and the teeth 27, so that the bottom end of the movable block 26 extends out of the protective block 21. After the cutting is completed, the cutting cylinder 16 drives the cutter 22 to rise. At this time, the cutter 22 drives the abutment block 23 to move upwards. The abutment block 23 contacts the movable block 26 and holds the movable block 26 to move upwards in the movable cavity 25. At this time, the teeth 27 cooperate with the third gear 29 to drive the rotating shaft 19 and the protective plate 17 to rotate toward the cutter 22.

[0030] Specifically, such as Figure 5 As shown, a rotation limiting groove 30 is provided in the protective block 21, and a rotation limiting block 31 is provided at the corresponding position of the rotation limiting groove 30 on the rotating shaft 19.

[0031] The rotation limit block 31 and the rotation limit groove 30 cooperate to limit the rotation of the rotating shaft 19, so that the cutter 22 is parallel to the protective plate 17.

[0032] The specific details of this plan are as follows: Rotating the second gear 11 via the lever 1101 can drive the rotating drum 8 to rotate via the first gear 10. At this time, the rotating drum 8, in conjunction with the screw 9, can drive the conveyor support 3 at one end of the conveyor belt 2 to rise and fall. The guide sleeve 4 guides the conveyor support 3, which can not only adjust the overall height of the conveyor belt 2, but also adjust the tilt angle of the conveyor belt 2, thereby adjusting the subsequent cutting angle.

[0033] By setting multiple sets of positioning rods 12 at the top of the conveyor belt 2, the multiple sets of positioning rods 12 are spaced apart. The spacing along the conveying direction of the conveyor belt 2 facilitates the cutting blade 22 to cut the bar material, while the positioning rods 12 spaced apart along the radial direction of the conveyor belt 2 allow the device to cut multiple sets of bar materials at the same time.

[0034] When a set of bars needs to be cut, the cutting cylinder 16 drives the cutter 22 to move downwards. At this time, the cutter 22 drives the stop block 23 to move downwards. The torsion spring 20 then drives the rotating shaft 19 and the protective plate 17 to rotate away from the cutter 22, thereby moving the cutter 22 away from the protective plate 17. The rotating limit block 31 and the rotating limit groove 30 cooperate to limit the rotation of the rotating shaft 19, preventing the protective plate 17 from directly touching the cutting cylinder 16 and not affecting the cutting of the bars by the protective plate 17. When the rotating shaft 19 rotates, the third gear 29 and the teeth 27 cooperate to drive the movable block 26 downwards. The movement causes the bottom end of the movable block 26 to extend out of the protective block 21. After the cutting is completed, the cutting cylinder 16 drives the cutter 22 to rise. At this time, the cutter 22 drives the abutment block 23 to move upward. The abutment block 23 contacts the movable block 26 and holds the movable block 26 to move upward in the movable cavity 25. At this time, the teeth 27 and the third gear 29 cooperate to drive the rotating shaft 19 and the protective plate 17 to rotate toward the cutter 22. The rotation limit block 31 and the rotation limit groove 30 cooperate to limit the rotation of the rotating shaft 19, so that the cutter 22 is parallel to the protective plate 17. At this time, the protective plate 17 protects the cutter 22.

[0035] When multiple sets of bars need to be cut, the electric slide rail 14 drives the cutting cylinder 16 to move laterally, so that the cutter 22 can cut along the positioning rods 12 of different sets in an alternating manner, thereby cutting multiple sets of bars.
