DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] like Figures 1 to 3 As shown, the present invention provides a stamping device for mold production, comprising a workbench 1, an upper bracket 2, a hydraulic rod 3 and a punch head 4, the upper bracket 2 is fixedly mounted on the top of the workbench 1, the hydraulic rod 3 is fixedly mounted on the top of the upper bracket 2, the punch head 4 is fixedly mounted on the output end of the hydraulic rod 3, an oil injection ring 5 is arranged inside the upper bracket 2, the rear side of the surface of the oil injection ring 5 is connected to an oil supply mechanism 6, and a detection component 7 is fixedly mounted on the back of the upper bracket 2.

[0024] refer to Figure 2 The oil supply mechanism 6 includes an oil supply pipe 61, which is connected to the rear side of the surface of the oil injection ring 5. A supporting plate 62 is fixedly installed at the bottom of the workbench 1, and a water pump 63 is fixedly installed on the right side of the top of the supporting plate 62. The output end of the water pump 63 is connected to the other end of the oil supply pipe 61, and the input end of the water pump 63 is connected to a connecting pipe 64, and the other end of the connecting pipe 64 is connected to an oil tank 65.

[0025] As a technical optimization solution of the present invention, by setting up the oil supply mechanism 6, when the operator needs to use the oil injection ring 5 to lubricate the punch head 4 by oil injection, the operator starts the water pump 63, and the water pump 63 draws lubricating oil from the oil tank 65, and transports it to the oil supply pipe 61 through the connecting pipe 64, and finally reaches the oil injection ring 5, so that the nozzle ring 8 can perform accurate oil injection work.

[0026] refer to Figure 2 The detection component 7 includes a controller 71, which is fixedly mounted on the back of the upper bracket 2. A limit switch 72 is fixedly mounted on the top of the upper bracket 2. The detection end of the limit switch 72 is located directly above the punch head 4. The limit switch 72 is electrically connected to the controller 71 through a wire, and the controller 71 is electrically connected to the hydraulic rod 3 and the water pump 63 through a wire.

[0027] As a technical optimization solution of the present invention, by setting the detection component 7, the limit switch 72 monitors the position of the punch head 4 in real time. Once it reaches the preset position, it immediately sends a signal to the controller 71. After receiving the signal, the controller 71 responds quickly to control the hydraulic rod 3 to stop rising, and at the same time controls the water pump 63 to supply oil as needed to lubricate the punch head 4. At the same time, when the punch head 4 drops away from the punch head 4, the controller 71 will control the water pump 63 to stop supplying oil to avoid waste caused by continuous oil spraying, while realizing intelligent lubrication.

[0028] refer to Figure 1 The top of the surface of the oil injection ring 5 is connected to a nozzle 8, and a plurality of nozzles 8 are arranged and are distributed in a circular shape with equal distances around the axis of the oil injection ring 5.

[0029] As a technical optimization solution of the present invention, by providing a nozzle 8, a plurality of nozzles 8 are evenly distributed on the oil spray ring 5, which can more evenly cover the surface of the punch head 4 and improve the lubrication efficiency and effect.

[0030] refer to Figure 3 The top of the oil tank 65 is provided with an oil filling port 9.

[0031] As a technical optimization solution of the present invention, by providing an oil filling port 9, when the lubricating oil in the oil tank 65 is insufficient, the operator can directly add lubricating oil through the oil filling port 9, which is convenient and quick, does not require shutdown operation, and improves production efficiency.

[0032] refer to Figure 2 Support rods 10 are fixedly installed on the left and right sides of the top of the surface of the fuel injection ring 5, and the top of the support rod 10 is fixedly connected to the upper bracket 2.

[0033] As a technical optimization solution of the present invention, by setting a support rod 10, the support rod 10 is fixed on the left and right sides of the top of the oil injection ring 5 and connected to the upper bracket 2 to form a stable support structure, thereby enhancing the stability of the oil injection ring 5 and ensuring that it will not be displaced due to vibration during operation.

[0034] refer to Figure 3 The back of the oil tank 65 is inlaid with an observation window 11 through a through groove, and the material of the observation window 11 is transparent acrylic.

[0035] As a technical optimization solution of the present invention, an observation window 11 is provided, and the observation window 11 is embedded in the through groove on the back of the oil tank 65. The observation window 11 is made of transparent acrylic material, which is convenient for the operator to observe the remaining amount and status of the lubricating oil in the oil tank 65 at any time.

[0036] The working principle and use process of the present invention are as follows: when in use, the operator fills the oil tank 65 with lubricating oil through the oil filling port 9, and then places the mold to be processed on the workbench 1, and starts the hydraulic rod 3 to press the punch head 4 downward. When the punching is completed, the operator controls the hydraulic rod 3 to drive the punch head 4 to move upward, and the limit switch 72 monitors the position of the punch head 4 in real time. Once the preset position is reached, a signal is immediately sent to the controller 71. After receiving the signal, the controller 71 responds quickly and controls the hydraulic rod 3 to stop. It rises and controls the water pump 63 to start as needed. The water pump 63 draws lubricating oil from the oil tank 65, transports it to the oil supply pipe 61 through the connecting pipe 64, and finally reaches the oil injection ring 5. The nozzle 8 on the oil injection ring 5 sprays the lubricating oil evenly on the punch head 4 to form a lubricating film, thereby reducing friction during the punching process and improving the convenience of lubrication for the operator. At the same time, when the punch head 4 drops away from the punch head 4, the controller 71 controls the water pump 63 to stop supplying oil to avoid waste caused by continuous oil injection and realize intelligent lubrication.

[0037] To sum up: this stamping device for mold production can automatically provide lubricating oil to the punch head 4 during the stamping process by setting an oil spray ring 5, effectively reducing the friction between the punch head 4 and the mold, reducing energy consumption, extending the service life of the equipment, and improving the surface finish and quality of the stamped parts. It solves the problem that the above-mentioned equipment is not equipped with an auxiliary lubrication structure. In order to ensure that the punch head can reduce wear and maintain the surface finish of the workpiece, the operator needs to manually apply or spray lubricating oil before each stamping. This manual-dependent lubrication method not only increases the labor intensity of the operator, but also leads to the problem of inconsistent lubrication effect.
