Technical Field
[0001] This utility model relates to the field of automotive stamping technology, specifically a precision guiding device for automotive stamping dies. Background Technology
[0002] With the rapid development of the automotive industry, the requirements for the precision and quality of parts are constantly increasing, especially in the field of new energy vehicles, where this demand is even more pronounced. Since automotive stamping dies are an indispensable part of automobile manufacturing, their precision guiding devices, as key components, directly affect the die's service life and production efficiency.
[0003] However, existing precision guiding devices for automotive stamping dies have the following problems: traditional stamping dies lack precise position confirmation and guiding devices, which easily leads to inaccurate material positioning in actual operation. Due to the lack of a positioning confirmation mechanism to ensure accurate alignment between the upper and lower dies, if the material placement is not precise enough or there is a slight deviation, it may lead to inaccurate dimensions, irregular shapes, or even damage to the die itself. In view of this, we propose a precision guiding device for automotive stamping dies. Utility Model Content

[0013] By employing the above technical solution, this utility model provides a precision guiding device for automotive stamping dies. It possesses at least the following beneficial effects:

When one of the positioning rod, the thick positioning rod and the thin positioning rod is not inserted, the stamping system will not be started because it is not subjected to air pressure, and the equipment will not be able to perform stamping operations. The operator needs to adjust the data to smoothly carry out the next operation. Through the guidance and confirmation of multiple positions, the production efficiency and product quality are improved, the scrap rate caused by position deviation is reduced, and the operation difficulty is also reduced, making the entire production process more intelligent and automated. The oil outlet on the smooth rod flows to the flow hole of the guide sleeve through the oil supply system, and then is delivered to the oil nozzle through the flow hole, so that the oil nozzle can flow out the lubricating oil, which can provide necessary lubrication during the stamping process, reduce the friction between the smooth rod and the guide sleeve, reduce wear, extend the service life of the smooth rod and the guide sleeve, and improve the processing smoothness.
[0015] (2) With the setting of the oil discharge device, after the stamping is completed, the waste oil for lubrication will flow through the oil discharge groove of the lower mold to the oil discharge pipe and then be discharged through the oil discharge pipe. There will be a large amount of stamping debris in the waste oil, which will adhere to the inner wall of the oil discharge pipe and cause blockage. At this time, the hydraulic cylinder stops operating and sends an electrical signal to the sensing block. The sensing block drives the rotating rod to rotate, and the rotating rod drives the knob to rotate and the striking rod to move up and down quickly. The striking rod strikes the top surface of the oil discharge pipe, which helps to loosen and remove the debris attached to the inner wall of the oil discharge pipe through physical vibration, preventing the oil discharge pipe from being blocked, thereby ensuring that the waste oil can be discharged smoothly from the system, maintaining the continuity of the entire stamping process and the normal operation of the equipment.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Example 1
[0025] A precision guiding device for automotive stamping dies, such as Figures 1-4 As shown, it includes a lower template 1, a lower mold 11 fixedly installed on the top of the lower template 1, an oil drain groove opened on the left side of the lower mold 11, a limit seat 12 fixedly installed on the outer wall of the lower mold 11, a fixing rod 13 fixedly installed on the top of the lower template 1 near the limit seat 12, an upper template 2 provided on the top of the lower template 1, an upper mold 21 fixedly installed on the bottom of the upper template 2, a positioning device 3 provided on the top of the lower template 1, and an oil drain device 4 provided on the outer wall of the lower mold 11.
[0026] The positioning device 3 includes a pressure plate 31, a fixed base 32, a positioning rod 33, a positioning sleeve 34, a coarse positioning sleeve 35, a coarse positioning rod 36, a fine positioning sleeve 37, and a fine positioning rod 38. The pressure plate 31 is fixedly installed on the inner wall of the bottom of the upper mold 21. The fixed base 32 penetrates and is fixedly installed on the bottom surface of the pressure plate 31. The positioning rod 33 is installed on the inner wall of the fixed base 32, and the positioning rod 33 is fixedly connected to the inner wall of the fixed base 32. The material is placed on the top of the lower mold 11, and the positioning hole of the material is aligned with the outer wall of the positioning rod 33 on the fixed base 32. The equipment is started, and the upper mold... The upper mold 21 moves downward via a hydraulic cylinder, causing the pressure plate 31 to move downward. A positioning sleeve 34 is installed on the top outer side of the pressure plate 31, and is fixedly connected to the top outer side of the pressure plate 31. A coarse positioning sleeve 35 is installed on the top inner side of the pressure plate 31, and is fixedly connected to the top inner side of the pressure plate 31. A coarse positioning rod 36 is installed on the top inner side of the lower mold 11, and is fixedly connected to the top inner side of the lower mold 11. A fine positioning sleeve 37 is installed on the top outer side of the pressure plate 31, away from the positioning sleeve 34, and is fixedly connected to the top outer side of the pressure plate 31, away from the positioning sleeve 34. The top of sleeve 34 is fixedly connected. The positioning thin rod 38 is installed on the top of the outer side of the lower mold 11. The positioning thin rod 38 is fixedly connected to the top of the outer side of the lower mold 11. The pressure plate 31 drives the positioning sleeve 34, the positioning coarse sleeve 35, and the positioning thin sleeve 37 to move downward. The positioning sleeve 34, the positioning coarse sleeve 35, and the positioning thin sleeve 37 will simultaneously insert the positioning rod 33, the positioning coarse rod 36, and the positioning thin rod 38 on the top of the lower mold 11 into their inner walls. After being inserted to the bottom, the air pressure inside the positioning sleeve 34, the positioning coarse sleeve 35, and the positioning thin sleeve 37 will cause the positioning rod 33, the positioning coarse rod 36, and the positioning thin rod 38 to be inserted into their inner walls. Simultaneously, 38 will retract downwards, thereby triggering the stamping system of the upper mold 21 to stamp the material. When one of the positioning rods 33, the coarse positioning rod 36, and the fine positioning rod 38 is not inserted, the stamping system will not be activated because it is not subjected to air pressure, and the equipment will not be able to perform stamping operations. The operator will then need to adjust the data to smoothly carry out the next operation. Through the guidance and confirmation of multiple positions, production efficiency and product quality are improved, the scrap rate caused by position deviation is reduced, and the operation difficulty is also reduced, making the entire production process more intelligent and automated.
[0027] The positioning device 3 also includes a guide rod 39, an oil outlet 310, a guide sleeve 311, and an oil nozzle 312. The guide rod 39 is installed on the top of the outer side of the lower mold 11 and is fixedly connected to the top of the outer side of the lower mold 11. The oil outlet 310 is opened on the outer wall of the guide rod 39. The guide sleeve 311 is installed on the top of the outer side of the upper mold 21. A flow hole is opened on the inner wall of the guide sleeve 311, and the oil outlet 310 is located on the movement trajectory of the flow hole. The guide sleeve 311 is fixedly connected to the top of the outer side of the upper mold 21. The oil nozzle 312 is installed on the top of the guide sleeve 311 and is fixedly connected to the top of the guide sleeve 311. Furthermore, the grease nipple 312 is connected to the flow hole of the guide sleeve 311. When the upper mold 21 moves the guide sleeve 311 downward, the guide rod 39 on the lower mold 11 will insert into the inner wall of the guide sleeve 311. After being inserted to the bottom, the oil outlet 310 on the guide rod 39 flows to the flow hole of the guide sleeve 311 through the oil supply system, and then is delivered to the grease nipple 312 through the flow hole, so that the grease nipple 312 can deliver lubricating oil. This can provide necessary lubrication during the stamping process, reduce the friction between the guide rod 39 and the guide sleeve 311, reduce wear, extend the service life of the guide rod 39 and the guide sleeve 311, and improve the smoothness of processing.
[0028] In use, the precision guiding device for an automotive stamping die of this utility model involves placing the material on the top of the lower die 11, aligning the positioning holes of the material with the outer wall of the positioning rod 33 on the fixed base 32, and starting the equipment. The upper die 21 moves downward via a hydraulic cylinder, causing the pressure plate 31 to move downward. The pressure plate 31 then moves the positioning sleeve 34, the coarse positioning sleeve 35, and the fine positioning sleeve 37 downward. Simultaneously, the positioning sleeves 34, 35, and 37 insert the positioning rod 33, the coarse positioning rod 36, and the fine positioning rod 38 from the top of the lower die 11 into their inner walls. After insertion to the bottom, the positioning sleeves 34, 35, and 37... The air pressure causes the positioning rod 33, the thick positioning rod 36, and the thin positioning rod 38 to retract downwards simultaneously, thereby triggering the stamping system of the upper mold 21 to stamp the material. When one of the positioning rods 33, the thick positioning rod 36, or the thin positioning rod 38 is not inserted, the stamping system will not be activated because it is not subjected to air pressure, and the equipment will not be able to perform the stamping operation. The operator will then need to adjust the data to successfully carry out the next operation. Through the guidance and confirmation of multiple positions, production efficiency and product quality are improved, the scrap rate caused by position deviation is reduced, and the operation difficulty is also reduced, making the entire production process more intelligent and automated.
[0029] When the upper mold 21 moves the guide sleeve 311 downward, the guide rod 39 on the lower mold 11 will insert into the inner wall of the guide sleeve 311. After being inserted to the bottom, the oil outlet 310 on the guide rod 39 flows to the flow hole of the guide sleeve 311 through the oil supply system, and then is delivered to the oil nozzle 312 through the flow hole, so that the oil nozzle 312 can deliver the lubricating oil. This can provide the necessary lubrication during the stamping process, reduce the friction between the guide rod 39 and the guide sleeve 311, reduce wear, extend the service life of the guide rod 39 and the guide sleeve 311, and improve the smoothness of processing.

[0031] like Figure 5 As shown, the oil draining device 4 includes a sensing block 41, a rotating rod 42, a knob 43, a striking rod 44, and an oil drain pipe 45. The sensing block 41 is wired to the outer wall of the lower mold 11. The rotating rod 42 is rotatably mounted on the outer wall of the sensing block 41 and is driven by the sensing block 41. The knob 43 is mounted on the end of the rotating rod 42 away from the sensing block 41, and the knob 43 is fixedly connected to the end of the rotating rod 42 away from the sensing block 41. The striking rod 44 is slidably mounted on the inner wall of the sensing block 41 and is driven by the rotating rod 42. The oil drain pipe 45 is mounted on the outer wall of the lower mold 11 near the bottom end of the striking rod 44 and is fixedly connected to the outer wall of the lower mold 11 near the bottom end of the striking rod 44. The top surface of the oil drain pipe 45 is located on the outer wall of the striking rod 44. During the motion trajectory, after the stamping is completed, the waste oil used for lubrication will flow through the oil drain groove of the lower die 11 to the oil drain pipe 45, and then be discharged through the oil drain pipe 45. The waste oil contains a large amount of stamping debris, which will adhere to the inner wall of the oil drain pipe 45 and cause blockage. At this time, the hydraulic cylinder stops operating and sends an electrical signal to the sensing block 41. The sensing block 41 drives the rotating rod 42 to rotate, and the rotating rod 42 drives the knob 43 to rotate and the striking rod 44 to move up and down rapidly. The striking rod 44 strikes the top surface of the oil drain pipe 45, which helps to loosen and remove the debris attached to the inner wall of the oil drain pipe 45 through physical vibration, preventing the oil drain pipe 45 from being blocked, thereby ensuring that the waste oil can be discharged smoothly from the system, maintaining the continuity of the entire stamping process and the normal operation of the equipment.
