Description

Technical Field

[0001] This invention belongs to the field of cutting tool heat treatment technology, specifically a quenching and tempering co-manufacturing equipment for carbon steel cutting tools. Background Technology

[0002] In carbon steel cutting tool manufacturing, quenching and tempering are the core heat treatment processes that determine their mechanical properties. These two processes must work closely together to ensure a stable internal structure and sufficient strength and toughness. Quenching lays the foundation for the tool's hardness, while tempering eliminates internal stresses generated after quenching, alleviates brittleness, and achieves a reasonable balance between hardness and toughness, preventing chipping and breakage during use. However, existing carbon steel cutting tool quenching and tempering equipment has significant shortcomings, failing to meet the demands of high-quality production. The most prominent issue is the poor linkage between the quenching and tempering processes. The two processes are independent and lack effective coordination. After quenching, the tool must be transferred before entering the tempering process, disrupting the continuity of the thermodynamic state after quenching and leading to uneven internal stress distribution, creating a potential problem for incomplete stress elimination in subsequent processes.

[0003] Meanwhile, the existing tempering equipment suffers from an unreasonable heat source arrangement, failing to achieve close contact between the heat source and the carbon steel cutting tool surface. This results in uneven heat transfer to all parts of the tool, leading to insufficient and uneven elimination of internal stress, with some areas retaining significant internal stress. The poor linkage and insufficient heat source contact exacerbate the problem of incomplete stress elimination, causing a decrease in the overall strength of the tool and preventing it from meeting design requirements. Therefore, there is an urgent need to develop a manufacturing equipment that can achieve coordinated quenching and tempering processes and ensure close contact between the tempering heat source and the tool, addressing the shortcomings of existing technology and improving the manufacturing quality of carbon steel cutting tools. Summary of the Invention

[0004] The purpose of this invention is to provide a quenching and tempering co-manufacturing device for carbon steel cutting tools, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a co-processing equipment for quenching and tempering carbon steel cutting tools, comprising a base assembly, a transport assembly fixedly mounted on the top of the base assembly, drive assemblies mounted on both the front and rear sides of the transport assembly, synchronization assemblies mounted on both the left and right sides of the two drive assemblies, a quenching assembly fixedly mounted on the top of the transport assembly, and a tempering assembly fixedly mounted on the right side of the quenching assembly; the tempering assembly includes a second gantry frame, two sets of hydraulic rods inserted into the top of the second gantry frame, connecting blocks movably hinged to the telescopic ends of the two sets of hydraulic rods, and a long plate fixedly connected to the bottom of every two sets of connecting blocks, with two heating wires installed on the inner side of the long plate.

[0006] Preferably, the two drive components and the two synchronization components are placed diagonally, and the fixed end of the hydraulic rod is suspended from the top of the second gantry. By changing the extension and retraction length of the four hydraulic rods on the left and right, the two long plates can be placed crosswise, thereby increasing the tempering heating area.

[0007] Preferably, the base assembly includes a concave plate, inside which multiple sleepers are installed at equal intervals, and a U-shaped tube is installed through the multiple sleepers. A water outlet pipe is fixedly connected to the left side of the U-shaped tube, the top of the sleepers is fixedly attached to the bottom of the transport assembly, and the U-shaped tube is fitted to the inner wall of the concave plate.

[0008] Preferably, the transport assembly includes two support plates, both of which are fixedly installed on the top of multiple sleepers. Two rotating shafts are rotatably installed on the inner side of the two support plates, and tracks are sleeved on the outer edges of the two rotating shafts. Multiple drainage holes are installed through the surface of the tracks.

[0009] Preferably, the track surface is provided with multiple grooves at equal intervals, the grooves are used to limit the carbon steel cutter, and the multiple drainage holes are the same size and the same spacing, and the drainage holes penetrate the upper and lower surfaces of the track.

[0010] Preferably, the drive assembly includes a motor, which is fixedly mounted on the front side of the support plate. The output shaft of the motor is fixedly connected to a first bevel gear, and the outer edge of the first bevel gear meshes with a second bevel gear. The rotation shaft of the second bevel gear passes through the support plate and is fixedly connected to the rotation shaft. The first bevel gear and the second bevel gear mesh perpendicularly.

[0011] Preferably, the synchronization component includes two sets of L-shaped blocks, which are fixedly installed in a cross shape on the front side of the support plate. Gear rings are fixedly installed on the inner side of the two sets of L-shaped blocks. Three planetary gears are meshed inside the gear rings. A sun gear is meshed inside the three planetary gears. One end of the sun gear passes through the support plate and is fixedly connected to the rotating shaft. The three planetary gears are evenly distributed in a ring between the sun gear and the gear ring, and the planetary gears mesh with the sun gear and the gear ring respectively.

[0012] Preferably, the quenching assembly includes a first gantry frame, which is fixedly installed on the top of the concave plate and spans the track. A water storage tank is fixedly installed on the front side of the first gantry frame. One end of the water storage tank is fixedly connected to a connecting pipe, and the other end of the connecting pipe is connected to a plurality of nozzles. The plurality of nozzles are fixedly installed at the bottom of the first gantry frame, and the spraying direction of the nozzles is towards the top of the track. The plurality of nozzles are evenly spaced.

[0013] The beneficial effects of this invention are as follows: 1. This invention solves the problem of insufficient heat source contact during tempering by installing an adjustable tempering assembly. The tempering assembly adjusts the height of the long plate via a hydraulic rod, allowing the heating wire to fit tightly against the surface of the carbon steel tool. At the same time, the angle of the long plate can be adjusted to increase the heating area, ensuring that heat is evenly transferred to all parts of the tool. This allows the internal quenching stress of the tool to be fully and evenly eliminated, effectively improving the strength and toughness of the carbon steel tool and avoiding problems such as tool chipping and breakage caused by residual stress, thus ensuring the manufacturing quality of the tool.

[0014] 2. This invention improves the linkage between quenching and tempering processes through the coordinated operation of transport components, drive components and synchronization components, enabling carbon steel tools to be directly transferred to the tempering process after quenching without additional transfer steps. This ensures the continuity of the thermodynamic state of the tool after quenching, avoids uneven stress distribution caused by temperature changes during transfer, solves the problem of poor linkage of existing equipment, and improves heat treatment efficiency and continuity.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] like Figures 1 to 7 As shown, this embodiment of the invention provides a co-manufacturing equipment for quenching and tempering carbon steel cutting tools, including a base assembly 1, a transport assembly 2 fixedly installed on the top of the base assembly 1, drive assemblies 3 installed on both the front and rear sides of the transport assembly 2, synchronization assemblies 4 installed on both the left and right sides of the two drive assemblies 3, a quenching assembly 5 fixedly installed on the top of the transport assembly 2, and a tempering assembly 6 fixedly installed on the right side of the quenching assembly 5; the tempering assembly 6 includes a second gantry frame 61, two sets of hydraulic rods 62 inserted into the top of the second gantry frame 61, and connecting blocks 63 movably hinged to the telescopic ends of the two sets of hydraulic rods 62, and a long plate 64 fixedly connected to the bottom of each pair of connecting blocks 63, with two heating wires 65 installed on the inner side of the long plate 64; the two drive assemblies 3 and the two synchronization assemblies 4 are placed diagonally, and the fixed ends of the hydraulic rods 62 are suspended from the top of the second gantry frame 61. By changing the telescopic length of the four hydraulic rods 62 on the left and right, the two long plates 64 can be arranged in a cross pattern, thereby increasing the tempering heating area; When the cutting tool is transported to the tempering assembly 6, the hydraulic rods 62 are activated. Based on the shape and size of the cutting tool, the extension lengths of the four hydraulic rods 62 are adjusted so that the two long plates 64 are arranged in a crisscross pattern, increasing the tempering heating area. Two heating wires 65 on the inner side of the long plates 64 are energized to generate heat. The hydraulic rods 62, through the connecting block 63, move the long plates 64 downwards, ensuring that the heating wires 65 are in close contact with the surface of the carbon steel cutting tool, guaranteeing uniform heat transfer to all parts of the tool. Through continuous heating by the heating wires 65, the internal stress generated after quenching is gradually eliminated, brittleness is alleviated, and the hardness and toughness of the tool are properly matched, thereby improving the tool's strength. The entire process achieves coordinated operation of the quenching and tempering processes. Simultaneously, the close contact of the heat sources ensures sufficient stress elimination, guaranteeing the heat treatment quality of the carbon steel cutting tool.

[0019] The base assembly 1 includes a concave plate 11, with multiple sleepers 12 installed at equal intervals inside the concave plate 11. A U-shaped tube 13 is installed through the multiple sleepers 12. A water outlet pipe 14 is fixedly connected to the left side of the U-shaped tube 13. The top of the sleepers 12 is fixedly attached to the bottom of the transport assembly 2. The U-shaped tube 13 is attached to the inner wall of the concave plate 11. The U-shaped tube 13 inside the concave plate 11 of the base assembly 1 can be used to introduce cooling medium, and it fits with the sleeper 12 to achieve overall heat dissipation of the equipment. The water seepage holes 23 on the surface of the track 22 can drain the water accumulated in the subsequent quenching process in time, so as to avoid water accumulation affecting the tool transportation and heat treatment effect.

[0020] The transport component 2 includes two support plates 21, both of which are fixedly installed on the top of multiple sleepers 12. Two rotating shafts are rotatably installed on the inner side of the two support plates 21, and a track 22 is sleeved on the outer edge of the two rotating shafts. Multiple drainage holes 23 are installed through the surface of the track 22. Multiple grooves are equidistantly arranged on the surface of the track 22. The grooves are used to limit the carbon steel cutters. The multiple drainage holes 23 are the same size and the same spacing, and the drainage holes 23 penetrate the upper and lower surfaces of the track 22. The cutting tool can be placed in the groove of the track 22 of the transport component 2. The groove limits the cutting tool and prevents it from shifting during transport. The drainage holes 23 on the surface of the track 22 can drain the water accumulated in the subsequent quenching process in time, so as to avoid water accumulation affecting the transport and heat treatment effect of the cutting tool.

[0021] The drive assembly 3 includes a motor 31, which is fixedly mounted on the front side of the support plate 21. The output shaft of the motor 31 is fixedly connected to a first bevel gear 32. The outer edge of the first bevel gear 32 meshes with a second bevel gear 33. The rotation shaft of the second bevel gear 33 passes through the support plate 21 and is fixedly connected to the rotation shaft. The first bevel gear 32 and the second bevel gear 33 mesh perpendicularly. After the motor 31 of the drive assembly 3 is started, it can drive the first bevel gear 32 to rotate. The first bevel gear 32 meshes perpendicularly with the second bevel gear 33, thereby driving the rotating shaft of the transport assembly 2 to rotate, and the rotating shaft drives the track 22 to run.

[0022] The synchronization component 4 includes two sets of L-shaped blocks 41, which are fixedly installed in a cross shape on the front side of the support plate 21. A gear ring 42 is fixedly installed on the inner side of the two sets of L-shaped blocks 41. Three planetary gears 43 are meshed inside the gear ring 42. A sun gear 44 is meshed inside the three planetary gears 43. One end of the sun gear 44 passes through the support plate 21 and is fixedly connected to the shaft. The three planetary gears 43 are evenly distributed in a ring between the sun gear 44 and the gear ring 42, and the planetary gears 43 mesh with the sun gear 44 and the gear ring 42 respectively. The synchronization component 4, through the meshing of the sun gear 44, planet gear 43 and gear ring 42, ensures that the two rotating shafts rotate synchronously, so that the track 22 can smoothly transport the tool and realize synchronous linkage between processes.

[0023] The quenching assembly 5 includes a first gantry frame 51, which is fixedly installed on the top of the concave plate 11 and spans the track 22. A water storage tank 52 is fixedly installed on the front side of the first gantry frame 51. A connecting pipe 53 is fixedly connected to one end of the water storage tank 52, and multiple nozzles 54 are connected to the other end of the connecting pipe 53. The multiple nozzles 54 are fixedly installed at the bottom of the first gantry frame 51, and the spraying direction of the nozzles 54 is towards the top of the track 22. The multiple nozzles 54 are evenly spaced. When the carbon steel cutting tool is transported to the quenching assembly 5 by the track 22, the quenching assembly 5 starts to work. The cooling medium in the water tank 52 is transported to multiple evenly distributed nozzles 54 through the connecting pipe 53. The nozzles 54 spray the cooling medium toward the cutting tool on the top of the track 22 to complete the quenching treatment of the cutting tool.

[0024] Working principle: When using this equipment, the carbon steel cutting tool is first placed in the groove of the track 22 of the transport component 2. The groove limits the cutting tool and prevents it from shifting during transport. After the motor 31 of the drive component 3 starts, it drives the first bevel gear 32 to rotate. The first bevel gear 32 meshes perpendicularly with the second bevel gear 33, thereby driving the rotating shaft of the transport component 2 to rotate. The rotating shaft drives the track 22 to rotate. The synchronization component 4, through the meshing of the sun gear 44, planetary gears 43 and gear ring 42, ensures that the rotating shafts on both sides rotate synchronously, so that the track 22 smoothly transports the cutting tool and realizes synchronous linkage between processes.

[0025] When the carbon steel cutting tool is conveyed by the track 22 to the area below the quenching assembly 5, the quenching assembly 5 begins operation. The cooling medium in the water tank 52 is delivered through the connecting pipe 53 to multiple evenly distributed nozzles 54. The nozzles 54 spray the cooling medium towards the cutting tool on top of the track 22, completing the quenching treatment of the tool. After quenching, the track 22 continues to smoothly convey the tool, directly transferring it to the area below the tempering assembly 6 on the right side, without requiring additional transfer steps. This ensures the continuity of the thermodynamic state of the tool after quenching and improves the coordination between the two processes.

[0026] The U-shaped tube 13 inside the concave plate 11 of the base assembly 1 can be used to introduce cooling medium, and it fits with the sleeper 12 to achieve overall heat dissipation of the equipment. The water seepage holes 23 on the surface of the track 22 can drain the water accumulated in the subsequent quenching process in time, so as to avoid water accumulation affecting the tool transportation and heat treatment effect.

[0027] When the cutting tool is transported to the tempering assembly 6, the hydraulic rods 62 are activated. Based on the shape and size of the cutting tool, the extension lengths of the four hydraulic rods 62 are adjusted so that the two long plates 64 are arranged in a crisscross pattern, increasing the tempering heating area. Two heating wires 65 on the inner side of the long plates 64 are energized to generate heat. The hydraulic rods 62, through the connecting block 63, move the long plates 64 downwards, ensuring that the heating wires 65 are in close contact with the surface of the carbon steel cutting tool, guaranteeing uniform heat transfer to all parts of the tool. Through continuous heating by the heating wires 65, the internal stress generated after quenching is gradually eliminated, brittleness is alleviated, and the hardness and toughness of the tool are properly matched, thereby improving the tool's strength. The entire process achieves coordinated operation of the quenching and tempering processes. Simultaneously, the close contact of the heat sources ensures sufficient stress elimination, guaranteeing the heat treatment quality of the carbon steel cutting tool.
