Description

Technical Field

[0001] This application relates to the field of stamping technology, and in particular to an automatic oil spraying device for feeding a punch press. Background Technology

[0002] The automatic oil spraying device for punch press feeding mainly consists of the following key parts: distributor: responsible for evenly distributing lubricating oil to each spraying point; oil supply pipe: connecting the distributor and the pneumatic oil pump to ensure smooth transmission of lubricating oil; pneumatic oil pump: driven by compressed air to provide stable and sufficient pressure for oil spraying; oil tank: storing lubricating oil to ensure continuous operation of the device; oil spraying electromechanical box: controlling the entire oil spraying process, including setting and adjusting parameters such as oil spraying time and oil spraying volume.

[0003] A search revealed Chinese Patent Publication No. CN215088193U, which discloses an automatic oil spraying device for punch press feeding. The device includes a distributor, an oil supply pipe, a pneumatic oil pump, an oil tank, and an oil spraying electromechanical box. One end of the distributor is connected to the oil supply pipe, and the other end is connected to the pneumatic oil pump. The pneumatic oil pump is equipped with an electric air valve that receives compressed air. The electric air valve is connected to the oil spraying electromechanical box via a control cable. The oil spraying electromechanical box is connected to the uncoiling machine electromechanical box. The pneumatic oil pump is also connected to the oil tank via an oil inlet pipe. This invention automatically sprays stamping oil onto the material being stamped during continuous punching. It employs a combination of electronic and pneumatic control to achieve uniform spraying of stamping oil. A certain amount of stamping oil is sprayed onto the product after each stamping operation. No oil is sprayed when there is no stamping to prevent excessive oil consumption and waste.

[0004] Regarding the aforementioned related technologies, the inventors have discovered the following drawbacks:

[0005] The nozzle is often equipped with a filter screen to trap small impurities. When too many impurities adhere to the filter screen, it can cause the nozzle to spray oil slowly or not at all. Therefore, the operator often needs to remove the filter screen, clean it, and reinstall it every once in a while, which affects the efficiency of oil injection.

[0006] Therefore, in response to the above problems, the applicant provides an automatic oil spraying device for punch press feeding. Utility Model Content

[0019] In summary, this application includes the following beneficial technical effects:

[0020] 1. This utility model, through the setting of the impurity scraping mechanism, uses a stepper motor to drive the threaded rod of the ball screw to rotate and cause the sliding end to drive the scraper to concentrate the impurities on the surface of the barrier screen into the impurity retention cavity.

[0031] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0032] This application discloses an automatic oil spraying device for punch press feeding.

[0033] like Figure 1-8 As shown, an automatic oil spraying device for punch press feeding includes an oil nozzle 11 and an oil tank 26. The oil tank 26 is equipped with an oil display mechanism, which includes a sliding column 3, a sliding float 4, a connecting float 5, a floating plate 6, a measuring rod 7, a magnetic levitation sensor 8, a display 9, and a buzzer 10. The sliding column 3 is slidably connected to the sliding float 4. One end of the sliding float 4 is fixedly connected to the connecting float 5. One end of the connecting float 5 is fixedly connected to the outer circumference of the floating plate 6. The measuring rod 7 is vertically fixedly connected to the top surface of the floating plate 6. The magnetic levitation sensor 8, the display 9, and the buzzer 10 are connected to an external power supply.

[0034] The oil outlet 11 is equipped with a scraping mechanism for removing impurities. The scraping mechanism includes a stepper motor 12, a ball screw 13 and a scraper 14. The rotating end of the stepper motor 12 is rotatably connected to the threaded rod of the ball screw 13, and the scraper 14 is fixedly connected to the sliding end of the ball screw 13.

[0035] Please see Figure 1It also includes an automatic oil spraying device, which consists of an electrical box 20, a pneumatic oil pump 21, an oil supply pipe 22, a distributor 23, an oil outlet pipe 24, an oil outlet nozzle 11, an oil inlet pipe 25, and an oil tank 26. The electrical box 20 and the pneumatic oil pump 21 are mounted on a connecting plate 1. One end of the connecting plate 1 is fixedly connected to the outer wall of the oil tank 26. An oil inlet pipe 25 and an oil supply pipe 22 are respectively installed at the inlet of the pneumatic oil pump 21. A distributor 23 is installed at one end of the oil supply pipe 22. Multiple oil outlet pipes 24 are installed at the bottom of the distributor 23. Oil outlet nozzles 11 are installed on the multiple oil outlet pipes 24 respectively. The structure and operating principle of the automatic oil spraying device are existing technologies and will not be described in detail here. At the same time, the oil outlet nozzle 11 performs the oil spraying process on the stamping material on the punch press.

[0036] Please see Figure 1 The oil inlet pipe 25 extends into the oil tank 26. An oil inlet cylinder 260 is provided on the top of the oil tank 26. A plug 261 is inserted into the oil inlet cylinder 260. The connecting plate 1 serves to position the electrical box 20 and the pneumatic oil pump 21. The plug 261 is inserted into the oil inlet cylinder 260 mainly to prevent oil from flowing out of the oil inlet cylinder 260. At the same time, the oil inlet cylinder 260 is mainly designed to facilitate the user to better guide the oil into the plug 261 through the oil inlet cylinder 260.

[0037] Please see Figure 2 Hezhi Figure 3 Multiple sliding columns 3 are fixedly connected in a ring array on the bottom inner wall of the oil tank 26. The distance between the top surface of the multiple sliding columns 3 and the top inner wall of the oil tank 26 is between 3cm and 5cm. Limiting grooves penetrate the inner and outer walls of the top of the oil tank 26. The measuring rod 7 extends out of the limiting groove. The function of the sliding columns 3 is to enable the sliding float 4 to move vertically upward or upward as the oil in the oil tank 26 increases or decreases. The sliding float 4, the connecting float 5 and the float plate 6 are all made of foam material. The foam material of the sliding float 4, the connecting float 5 and the float plate 6 can better support the measuring rod 7. At the same time, the setting of the limiting groove is also to limit the measuring rod 7.

[0038] Please see Figure 2 and Figure 4A magnetic levitation sensor 8 and a display 9 are installed on the top surface of the fuel tank 26. A buzzer 10 is installed on the top of the display 9. The measuring rod 7 is engraved with a scale value 70. The magnetic levitation sensor 8 is located on the side near the scale value 70. The magnetic levitation sensor 8, the display 9, and the buzzer 10 are all externally powered. The scale value 70 is a magnetic mark. The magnetic levitation sensor 8 can sense the position of the scale value 70 on the float and convert it into an electrical signal, which is transmitted to the display 9. A controller is installed in the display 9. When the fuel in the fuel tank 26 is about to run out, a certain range is set. When the set fuel range is reached, the magnetic levitation sensor 8 senses the scale value 70 and transmits the signal to the controller in the display 9. The controller controls the buzzer 10 to sound an alarm and remind the user to add fuel.

[0039] Please see Figure 2 and Figure 4 A magnetic levitation sensor 8 and a display 9 are installed on the top surface of the fuel tank 26. A buzzer 10 is installed on the top of the display 9. The measuring rod 7 is engraved with a scale value 70. The magnetic levitation sensor 8 is located on the side near the scale value 70. The magnetic levitation sensor 8, the display 9, and the buzzer 10 are all externally powered. The scale value 70 is a magnetic mark. The magnetic levitation sensor 8 can sense the position of the scale value 70 on the float and convert it into an electrical signal, which is transmitted to the display 9. A controller is installed in the display 9. When the fuel in the fuel tank 26 is about to run out, a certain range is set. When the set fuel range is reached, the magnetic levitation sensor 8 senses the scale value 70 and transmits the signal to the controller in the display 9. The controller controls the buzzer 10 to sound an alarm and remind the user to add fuel.

[0040] Please see Figures 6 to 8 The oil outlet 11 consists of an internally threaded cylinder 110, a square cylinder 111, an impurity collection cylinder 112, and a nozzle outlet end 113. The internally threaded cylinder 110 is threadedly connected to the external thread of the oil outlet pipe 24. Two impurity collection cylinders 112 are connected to the nozzle outlet end 113. Each of the two impurity collection cylinders 112 has an impurity retention chamber 1120. Impurity inlet chambers 1110 are opened on both sides of the square cylinder 111. The impurity inlet chambers 1110 are connected to the impurity retention chambers 1120. A threaded cylinder 1121 is threadedly connected to the impurity collection cylinder 112. When the oil outlet 11 stops supplying oil, the internally threaded cylinder 110 can be unscrewed from the oil outlet pipe 24, and the threaded cylinder 1121 can be unscrewed from the impurity collection cylinder 112. Impurities in the impurity collection cylinder 112 can be discharged by rinsing the internally threaded cylinder 110 with a water gun.

[0041] Please see Figures 6 to 8One of the impurity collection cylinders 112 has a stepper motor 12 installed on its top. The stepper motor 12 is connected to an external power supply. The rotating end of the stepper motor 12 passes through one side of the square cylinder 111. A sealing ring is installed on the rotating end of the stepper motor 12. The sealing ring is located on the rotating end of the stepper motor 12 and on one side of the oil outlet 11. It is mainly to prevent oil leakage and plays a sealing role.

[0042] Please see Figures 6 to 8 A slot is provided on the square cylinder 111, and a barrier net 15 is installed in the slot. The scraper 14 contacts the barrier net 15. The back and forth movement of the ball screw 13 drives the barrier net 15 to move synchronously. The scraper 14 moving on the barrier net 15 will scrape off the impurities on its surface and move them into the impurity inlet cavity 1110. As the impurities descend due to gravity, they will settle in the impurity retention cavity 1120.

[0043] The implementation principle of the automatic oil spraying device for punch press feeding in this application embodiment is as follows:

[0044] As the oil in the tank 26 decreases due to the spray from the nozzle 11, the sliding float 4, the connecting float 5, and the float plate 6 floating on the oil cause the measuring rod 7 to descend as the oil decreases. The descent of the measuring rod 7 enables the magnetic levitation sensor 8 to sense the position of the scale value 70 on the float and convert it into an electrical signal, which is then transmitted to the display 9. The user can clearly know the remaining amount of oil in the tank 26 through the data displayed on the display 9.

[0045] When the set oil level is reached, the magnetic levitation sensor 8 senses the scale value 70 and transmits the signal to the controller in the display 9. The controller controls the buzzer 10 to alarm and remind the user to add oil in advance, so as to avoid the situation where the oil tank 26 is empty and the oil nozzle 11 cannot spray oil without the user's knowledge.

[0046] The controller controls the stepper motor 12 to work intermittently. The rotation of the stepper motor 12 drives the threaded rod of the ball screw 13 to rotate. The threaded rod of the ball screw 13 drives the sliding end to move horizontally. The sliding end of the ball screw 13 drives the scraper 14 to contact the barrier mesh 15 to scrape and move the impurities on the surface to the impurity inlet cavity 1110. At this time, the impurities are concentrated in the impurity inlet cavity 1110. The weight of the impurities will cause them to sink into the impurity retention cavity 1120. Refer to the attached diagram in the instruction manual. Figure 8 As shown;

[0047] As described above, the scraper 14 moves back and forth on the surface of the barrier screen 15 to periodically clean impurities from the surface of the barrier screen 15, preventing excessive accumulation of impurities on the barrier screen 15, which could lead to blockage of the oil outlet 11 and cause no oil to be produced.

[0048] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
