Description

Technical Field

[0001] The utility model relates to the technical field of tool welding, and more specifically, to a tool welding device. Background Art

[0002] High-carbon, high-alloy martensitic stainless steel is commonly used for the blades of mid- to high-end kitchen knives. The welding quality of high-carbon, high-alloy blades places very high demands on the welding process, including the selection of welding parameters, the choice of welding materials, and pre-welding preparation. If the welding process is not appropriate, it can easily lead to unstable quality of the welded joint, thus affecting the service life and safety of the blade. Therefore, strict welding process and quality control measures are necessary to ensure the quality and stability of the welded joint, while reducing welding deformation and cracking, thereby improving the service life and safety of the blade. As for the welding of knives, due to the differences in the shape of different knives and the different welding temperatures for different materials, the current conventional practice is to weld knives manually. Manual welding is not only inefficient, but also difficult to control quality, which can easily lead to quality instability. Utility Model Content

[0003] The purpose of the utility model is to overcome the problems of low efficiency and unstable quality of manual welding and to provide a tool welding device that can automatically weld tools, thereby standardizing welding operations and is applicable to welding tools of different materials and shapes.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A tool welding device, comprising

[0006] Several limiting mechanisms for placing and limiting the tool;

[0007] Spot welding mechanism, used for spot welding of cutting tools;

[0008] Preheating mechanism, used for preheating the tool;

[0009] Welding mechanism, used for welding cutting tools;

[0010] a conveying mechanism for conveying a tool from the spot welding mechanism to the preheating mechanism, and for conveying a tool from the preheating mechanism to the welding mechanism;

[0011] The control mechanism is used to control the entire process of tool welding and is respectively communicated with the spot welding mechanism, preheating mechanism, welding mechanism, and transmission mechanism;

[0012] There are at least three limiting mechanisms, which are arranged in the spot welding mechanism, the preheating mechanism and the welding mechanism.

[0013] The present invention integrates tool positioning spot welding, preheating, and welding in one, so that after the tool is loaded, it can realize spot welding, preheating, and welding in sequence; the tool is positioned by a limiting mechanism, so that the tool can be accurately positioned during the spot welding, preheating, and welding processes, and a control mechanism is used for unified control, including but not limited to the start and stop of the spot welding mechanism and the control of the spot welding temperature and duration. After spot welding, the tool welding part is preheated by the preheating mechanism, which helps to reduce the cooling rate of the weld, drive off moisture, and prevent the possibility of hydrogen accumulation and cracking. The preheating temperature should be determined according to the specific composition of the tool used. After preheating, the tool is transported to the welding mechanism for welding by a conveying mechanism. Since the welding positioning has been carried out in the spot welding mechanism, when the welding mechanism is used for overall welding, it is only necessary to strengthen the firmness of the welding along the weld, and there is no need to worry about the connection position of the tool being offset, which reduces the difficulty of welding, thereby improving the welding quality and reducing problems such as cracking and deformation during the welding process. The limiting mechanism primarily positions the handle and blade separately, allowing for precise welding of the handle and blade, minimizing the weld seam. The limiting mechanism is highly versatile and can be applied to welding tools of different materials and shapes. This new tool welding device automatically welds tools, standardizing welding operations and ensuring weld quality across batches.

[0014] Furthermore, the conveying mechanism includes a first conveying mechanism and a second conveying mechanism. The first conveying mechanism is used to convey the tool from the spot welding mechanism to the preheating mechanism, and the second conveying mechanism is used to convey the tool from the preheating mechanism to the welding mechanism. Both the first conveying mechanism and the second conveying mechanism serve as a conveying mechanism. The first conveying mechanism is designed based on the arrangement position and distance between the spot welding mechanism and the preheating mechanism, and the second conveying mechanism is designed based on the arrangement position and distance between the preheating mechanism and the welding mechanism, so that the tool can be automatically conveyed throughout the entire welding process.

[0015] Furthermore, the first conveying mechanism includes a motor and a turntable, which is connected to the output shaft of the motor and is divided into a loading station, a spot welding station, a preheating station, and a unloading station along the direction of rotation of the turntable. The spot welding mechanism is located at the spot welding station, the preheating mechanism is located at the preheating station, and the second conveying mechanism is located at the unloading station. The limiting mechanism is provided on the turntable at a position corresponding to each station. The motor drives the turntable to rotate, thereby driving the tool to switch between different stations. Specifically, the tool always remains in the position on the limiting mechanism and does not change, and the relative position of the tool and the turntable does not change. However, as the turntable rotates, the tool is driven to switch from the loading station to the spot welding station, and then to the preheating station after the spot welding is completed. After the preheating is completed, it switches to the unloading station, and then the second conveying mechanism is used to transfer the tool to the welding mechanism to perform the final welding.

[0016] Furthermore, the second transfer mechanism is a robotic arm. The robotic arm has multiple degrees of freedom, which can realize position movement and angle rotation, thereby facilitating the transfer of the tool from the blanking station to the welding mechanism; preferably, the robotic arm is a six-axis robotic arm, capable of movement in the three directions of X / Y / Z and rotation in the three directions.

[0017] Furthermore, the spot welding mechanism includes a spot welding bracket, a spot welding connecting frame, and a first welding gun. The spot welding bracket is installed beside the turntable and is located at the spot welding station and is movably connected to the spot welding connecting frame. The first welding gun is movably connected to the spot welding connecting frame. The spot welding bracket is used to install the spot welding connecting frame, and the spot welding connecting frame is used to install the first welding gun. The spot welding connecting frame and the spot welding bracket are slidably connected, so that the relative position of the spot welding connecting frame and the spot welding bracket can be adjusted, thereby driving the relative movement of the first welding gun, thereby adjusting the spot welding position so that it can adapt to different tools when spot welding. The first welding gun is rotatably connected to the spot welding connecting frame to facilitate the first welding gun to adjust the spot welding angle and achieve spot welding at different positions of different tools.

[0018] Furthermore, the spot welding connection frame includes a sliding portion and a rotating portion. The sliding portion is slidably connected to the spot welding bracket, the rotating portion is movably connected to the sliding portion, and the first welding gun is rotatably connected to the rotating portion. The sliding portion is used to enable the spot welding connection frame to slide relative to the spot welding bracket, and the rotating portion is used to enable the first welding gun to rotate relative to the sliding portion. The rotating portion and the sliding portion can also move up and down to adjust the height of the first welding gun to accommodate tools of different shapes.

[0019] Furthermore, the preheating mechanism includes a preheating bracket, a preheating connecting bracket, and a heating element. The preheating connecting bracket is installed beside the turntable and is located at the preheating station and is slidably connected to the preheating connecting bracket. The heating element is fixedly installed on the preheating connecting bracket. The preheating bracket is used to install the preheating connecting bracket. The preheating connecting bracket can slide relative to the preheating bracket, thereby driving the heating element to slide relative to the preheating bracket to adjust the position of the tool preheating; the preheating connecting bracket is used to install the heating element. Preferably, the heating element is a resistance wire, which is used to heat the tool weld. The heating element has an efficient preheating function and can heat the area around the weld joint to a specified temperature before welding. It helps to reduce the cooling rate of the weld, drive off moisture, and prevent the possibility of hydrogen accumulation and cracking. Specifically, when the tool uses a martensitic stainless steel blade, the preheating temperature should be determined according to the specific composition of the martensitic stainless steel blade used.

[0020] Furthermore, the welding mechanism includes a welding bracket, a welding connection frame, and a second welding gun. The welding connection frame is slidably connected to the welding bracket, and the second welding gun is mounted on the welding connection frame. The welding bracket is used to mount the welding connection frame, which is used to mount the second welding gun. The welding connection frame can slide relative to the welding bracket, thereby driving the second welding gun to move relative to the welding bracket to adjust the welding position of the tool. Preferably, the first welding gun and the second welding gun have the same structure. The control mechanism controls the welding temperature, welding duration, and welding position, thereby achieving the spot welding function of the spot welding mechanism and the welding function of the welding mechanism.

[0021] Furthermore, the limiting mechanism includes a first limiting mechanism provided on the turntable and a second limiting mechanism provided on the welding bracket; the first limiting mechanism includes a handle limiting portion and a blade limiting portion, the handle limiting portion being located next to the blade limiting portion; the second limiting mechanism is provided with a plurality of blade limiting units. Placing the handle on the handle limiting portion prevents the handle from moving during the rotation of the turntable, and placing the blade on the blade limiting portion also prevents the blade from moving during the rotation of the turntable; specifically, the outer contours of the handle and blade can be limited by providing a plurality of limiting protrusions on the handle limiting portion and the blade limiting portion, or a process hole can be provided on the blade or handle so that the process hole cooperates with the limiting protrusion to achieve the limiting function, or other limiting structures can be used. The limiting unit of the second limiting mechanism is also a protrusion, and the outer contour of the blade can be limited by cooperating with a plurality of limiting protrusions. For tools of different shapes, the limiting function can be achieved by replacing the limiting mechanism. The limiting protrusion on the limiting mechanism can also be made movable, and the limiting protrusion can be adjusted and tightened with fasteners to achieve the limiting of different tools. It is also possible to provide multiple mounting holes on the limiting mechanism and use the limiting protrusions to plug into different mounting holes to achieve the limiting of tools of different shapes. The tool can also be limited by suction through pneumatic means.

[0022] Furthermore, the machine tool further includes a frame on which the spot welding mechanism, the preheating mechanism, and the first conveying mechanism are all mounted. The frame is used to mount the first conveying mechanism, the spot welding mechanism, and the preheating mechanism, so that the spot welding mechanism and the preheating mechanism are integrated again. The first conveying mechanism enables the tool to switch between the spot welding and preheating processes.

[0023] The beneficial effects of the utility model are:

[0024] ① Welding port positioning function: The limit mechanism can be used to position the tool handle and blade according to the tool connection positioning requirements, and pneumatic adsorption is used to limit the position to achieve the positioning of the spot welding joint.

[0025] ② Welding Preheating: The welding mechanism features an efficient preheating function that heats the area surrounding the weld joint to a specified temperature before welding. This helps reduce the cooling rate of the weld, drives off moisture, and prevents hydrogen accumulation and the possibility of cracking. The preheating temperature should be determined based on the specific composition of the martensitic stainless steel blade being used.

[0026] ③ Temperature Control Accuracy: The control mechanism can precisely control the preheat temperature to ensure uniform temperature of the weld joint, avoiding welding quality problems caused by excessively high or low temperatures. At the same time, the welding device also has a temperature monitoring and feedback system that can adjust the preheat temperature in real time to ensure the stability of the welding process.

[0027] ④Easy to operate: The welding device is easy to operate and maintain, which can reduce the operator's labor intensity and improve production efficiency. In addition, the welding device also has safety protection functions to ensure the safety of the operator. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0038] Example 1

[0039] like Figures 1 to 5 The figure shows a first embodiment of a tool welding device of the present invention, which includes a plurality of limiting mechanisms for placing and limiting the tool 8;

[0040] Spot welding mechanism 2, used for spot welding of tool 8;

[0041] A preheating mechanism 3, used for preheating the tool 8;

[0042] Welding mechanism 4, used for welding the tool 8;

[0043] a conveying mechanism for conveying the tool 8 from the spot welding mechanism 2 to the preheating mechanism 3 , and for conveying the tool 8 from the preheating mechanism 3 to the welding mechanism;

[0044] The control mechanism is used to control the entire welding process of the tool 8 and is respectively connected to the spot welding mechanism 2, the preheating mechanism 3, the welding mechanism 4, and the transmission mechanism 51;

[0045] There are at least three limiting mechanisms, which are all provided in the spot welding mechanism 2 , the preheating mechanism 3 , and the welding mechanism 4 .

[0046] The present invention integrates tool positioning, spot welding, preheating, and welding in one, so that the tool 8 can realize spot welding, preheating, and welding in sequence after loading; the tool 8 is positioned by a limiting mechanism, so that the tool 8 can be accurately positioned during the process of welding, preheating, and welding. Moreover, a control mechanism is used for unified control, including but not limited to the start and stop of the operation of the spot welding mechanism 2 and the control of the spot welding temperature and duration. After spot welding, the preheating mechanism 3 is used to preheat the welding part of the tool 8, which helps to reduce the cooling rate of the weld, drive off moisture, and prevent the possibility of hydrogen accumulation and cracking. The preheating temperature should be determined according to the specific composition of the tool 8 used. After preheating, the tool 8 is transported to the welding mechanism 4 for welding by a conveying mechanism. Since the welding positioning has been carried out in the spot welding mechanism 2, when the welding mechanism 4 is used for overall welding, it is only necessary to strengthen the firmness of the welding along the weld, without worrying about the displacement of the connection position of the tool 8, which reduces the difficulty of welding, thereby improving the welding quality and reducing problems such as cracking and deformation during welding. The limiting mechanism primarily positions the handle and blade, respectively, allowing for precise welding of the handle and blade, minimizing weld seams. The limiting mechanism is highly versatile and can be applied to welding tools 8 made of different materials and shapes. The tool welding device of this utility model can automatically weld tools 8, thereby standardizing welding operations and ensuring welding quality across batches.

[0047] As an improvement to this embodiment, the conveying mechanism includes a first conveying mechanism 51 and a second conveying mechanism 52. The first conveying mechanism 51 is used to convey the tool 8 from the spot welding mechanism 2 to the preheating mechanism 3, and the second conveying mechanism 52 is used to convey the tool 8 from the preheating mechanism 3 to the welding mechanism 4. The first conveying mechanism 51 and the second conveying mechanism 52 both have a conveying function. The first conveying mechanism 51 is designed based on the arrangement position and distance between the spot welding mechanism 2 and the preheating mechanism 3, and the second conveying mechanism 52 is designed based on the arrangement position and distance between the preheating mechanism 3 and the welding mechanism 4, so that the tool 8 can be automatically conveyed throughout the welding process.

[0048] As an improvement to this embodiment, the first conveying mechanism 51 includes a motor 511 and a turntable 512. The turntable 512 is connected to the output shaft of the motor 511 and is divided into a loading station 61, a spot welding station 62, a preheating station 63, and an unloading station 64 along the rotation direction of the turntable 512. The spot welding mechanism 2 is located at the spot welding station 62, the preheating mechanism 3 is located at the preheating station 63, and the second conveying mechanism 52 is located at the unloading station 64. Limiting mechanisms are provided on the turntable 512 corresponding to the positions of the various stations. The motor 511 drives the turntable 512 to rotate, thereby driving the tool 8 to switch between different stations. Specifically, the tool 8 always maintains its position on the limit mechanism and does not change, and the relative position of the tool 8 and the turntable 512 does not change. However, as the turntable 512 rotates, the tool 8 can be switched from the loading station 61 to the spot welding station 62, and then transferred to the preheating station 63 after the spot welding is completed. After the preheating is completed, it switches to the unloading station 64, and then uses the second conveying mechanism 52 to transfer the tool 8 to the welding mechanism 4 to perform the final welding.

[0049] As an improvement to this embodiment, the second transfer mechanism 52 is a robotic arm. The robotic arm has multiple degrees of freedom, enabling positional movement and angular rotation, thereby facilitating the transfer of the tool 8 from the blanking station 64 to the welding mechanism 4. Preferably, the robotic arm is a six-axis robotic arm capable of movement and rotation in the X, Y, and Z directions.

[0050] As an improved solution of this embodiment, the spot welding mechanism 2 includes a spot welding bracket 21, a spot welding connecting frame 22, and a first welding gun 23. The spot welding bracket 21 is installed next to the turntable 512 and is located at the spot welding station 62 and is movably connected to the spot welding connecting frame 22. The first welding gun 23 is movably connected to the spot welding connecting frame 22. The spot welding bracket 21 is used to install the spot welding connecting frame 22, and the spot welding connecting frame 22 is used to install the first welding gun 23. Through the sliding connection between the spot welding connecting frame 22 and the spot welding bracket 21, the relative position of the spot welding connecting frame 22 and the spot welding bracket 21 can be adjusted, thereby driving the first welding gun 23 to move relative to each other, thereby adjusting the spot welding position so that it can adapt to different tools 8 when spot welding. The first welding gun 23 is rotatably connected to the spot welding connecting frame 22 so that the first welding gun 23 can adjust the spot welding angle and achieve spot welding of different positions of different tools 8.

[0051] As an improvement to this embodiment, the preheating mechanism 3 includes a preheating bracket 31, a preheating connecting bracket 32, and a heating element 33. The preheating connecting bracket 32 is mounted adjacent to the turntable 512 and located at the preheating station 63, and is slidably connected to the preheating connecting bracket 32. The heating element 33 is fixedly mounted to the preheating connecting bracket 32. The preheating bracket 31 is used to mount the preheating connecting bracket 32. The preheating connecting bracket 32 can slide relative to the preheating bracket 31, thereby driving the heating element 33 to slide relative to the preheating bracket 31 to adjust the preheating position of the tool 8. The preheating connecting bracket 32 is used to mount the heating element 33. Preferably, the heating element 33 is a resistance wire used to heat the weld of the tool 8. The heating element 33 has an efficient preheating function and can heat the area around the weld joint to a specified temperature before welding. This helps to reduce the cooling rate of the weld, drive off moisture, and prevent hydrogen accumulation and the possibility of cracking. Specifically, when the tool 8 uses a martensitic stainless steel blade, the preheating temperature should be determined based on the specific composition of the martensitic stainless steel blade used. The preheating temperature is set according to the carbon content of the material, and is generally in the range of 200-560° C. The heating element 33 can be an induction heater, which positions and preheats the spot-welded tool 8 before transferring it to the welding mechanism 4 .

[0052] As an improvement to this embodiment, the welding mechanism 4 includes a welding bracket 41, a welding connecting frame 42, and a second welding gun 43. The welding connecting frame 42 is slidably connected to the welding bracket 41, and the second welding gun 43 is mounted on the welding connecting frame 42. The welding bracket 41 is used to mount the welding connecting frame 42, and the welding connecting frame 42 is used to mount the second welding gun 43. The welding connecting frame 42 can slide relative to the welding bracket 41, thereby driving the second welding gun 43 to move relative to the welding bracket 41 to adjust the welding position of the tool 8; preferably, the first welding gun 23 and the second welding gun 43 have the same structure, and the welding temperature, welding duration, and welding position are controlled by the control mechanism, thereby achieving the spot welding function of the spot welding mechanism 2 and the welding function of the welding mechanism 4.

[0053] As an improvement to this embodiment, the limiting mechanism includes a first limiting mechanism 11 disposed on the turntable 512 and a second limiting mechanism 12 disposed on the welding bracket 41. The first limiting mechanism 11 includes a handle limiting portion and a blade limiting portion, with the handle limiting portion located adjacent to the blade limiting portion. The second limiting mechanism 12 is provided with a plurality of blade limiting units. The handle is placed on the handle limiting portion to prevent the handle from moving during the rotation of the turntable 512, and the blade is placed on the blade limiting portion to similarly prevent the blade from moving during the rotation of the turntable 512. Specifically, the outer contours of the handle and blade can be limited by providing a plurality of limiting protrusions on the handle limiting portion and the blade limiting portion. Alternatively, a process hole can be provided on the blade or handle so that the process hole cooperates with the limiting protrusion to achieve the limiting function. Other limiting structures are also possible. The limiting units of the second limiting mechanism 12 are also protrusions, and the blade outer contour is limited by the cooperation of multiple limiting protrusions. For tools 8 of different shapes, the limiting function can be achieved by replacing the limiting mechanism. The limiting protrusion on the limiting mechanism can also be made movable, and the limiting protrusion can be adjusted and tightened with a fastener to achieve the limiting of different tools 8. It is also possible to provide multiple mounting holes on the limiting mechanism and use the limiting protrusions to plug into different mounting holes to achieve the limiting of tools 8 of different shapes. The tool 8 can also be limited by suction by pneumatic means.

[0054] As an improvement to this embodiment, a frame 7 is further included. The spot welding mechanism 2, the preheating mechanism 3, and the first conveying mechanism 51 are all mounted on the frame 7. The frame 7 is used to mount the first conveying mechanism 51, the spot welding mechanism 2, and the preheating mechanism 3, so that the spot welding mechanism 2 and the preheating mechanism 3 are integrated again. The tool 8 can be switched between the spot welding and preheating processes via the first conveying mechanism 51.

The sliding portion 221 is slidably connected to the spot welding bracket 21, the rotating portion 222 is movably connected to the sliding portion 221, and the first welding gun 23 is rotatably connected to the rotating portion 222. The sliding portion 221 is used to enable the spot welding connecting frame 22 to slide relative to the spot welding bracket 21, and the rotating portion 222 is used to enable the first welding gun 23 to rotate relative to the sliding portion 221. The rotating portion 222 and the sliding portion 221 can also move up and down, thereby adjusting the height of the first welding gun 23 to accommodate tools 8 of different shapes.

[0057] Example 3

[0058] This embodiment is another embodiment of a tool welding device. This embodiment is similar to the first embodiment, except that two first welding guns 23 are provided, symmetrically arranged about the spot welding connecting frame 22.
