Description

Technical Field

[0001] The present invention relates to the technical field of automatic punching, and particularly relates to an automatic punching device. Background Art

[0002] Automatic punching machines usually adopt numerical control technology. Through the computer control system, according to the preset programs and parameters, the punching operation is automatically completed. Some devices are also equipped with a machine vision system, which can scan and position the material to further improve the punching accuracy. Automatic punching devices have the advantages of high precision, high efficiency, versatility, simple operation, and low cost. When processing metal materials such as stainless steel and alloys, a cooling system needs to be equipped to cool the drill bit. The existing cooling method of punching devices is to spray water or coolant onto the drill bit and the drilling position. This cooling spraying method causes the coolant to flow away directly after contacting the drill bit, resulting in low heat transfer efficiency of the coolant, requiring a large amount of coolant, and the debris generated during drilling will adhere to the surface of the metal material, affecting the drilling quality. For this reason, we propose an automatic punching device. Summary of the Invention

[0003] The purpose of the present invention is to solve the shortcomings in the background art and propose an automatic punching device.

[0004] To achieve the above object, the technical solution adopted by the present invention is: an automatic punching device, including a fixed workbench. Two groups of Y-axes are arranged at the upper end of the fixed workbench. An X-axis is arranged at the upper ends of the two groups of Y-axes. A Z-axis is arranged at the front end of the X-axis. A C-axis is arranged at the lower end of the Z-axis. An A-axis is arranged on one side of the C-axis. The A-axis includes a drilling machine. A drill bit is arranged at the lower end of the drilling machine. A cooling component is arranged outside the drill bit. The cooling component includes an annular shell arranged outside the drill bit. A pressure member is arranged at the upper end of the annular shell. A blowing component is arranged at the front end of the drilling machine.

[0005] Preferably, a bottom ring is fixedly connected to the lower end of the annular shell. Through holes are formed inside the bottom ring. The aperture of the through holes is larger than the diameter of the drill bit. Two symmetrically arranged bottom plates are fixedly connected to the outside of the bottom ring. The bottom plates are L-shaped. A connecting plate is fixedly connected to the outside of the annular shell. A water storage cylinder is fixedly connected to the upper end of the connecting plate. The water storage cylinder is communicated with the annular shell. The water storage cylinder is connected to the coolant pipeline.

[0006] Preferably, the pressure member includes an upper shell fixedly connected to the annular shell. An inner hole is formed at the upper end of the upper shell. An air groove is arranged inside the upper shell. A pressing ring is slidably connected inside the air groove. A second spring is fixedly connected to the upper end of the pressing ring. The second spring is fixedly connected to the upper shell.

[0007] Preferably, a buffer member is provided at the upper end of the connecting plate. The buffer member includes a fixing plate fixedly connected to the drill rig. A pressing rod is fixedly connected to the lower end of the fixing plate. A buffer cylinder is fixedly connected to the upper end of the connecting plate. The pressing rod is inserted inside the buffer cylinder. A first spring is fixedly connected to the inside of the buffer cylinder. The upper end of the first spring is fixedly connected to the pressing rod.

[0008] Preferably, the blowing assembly includes a first mounting plate fixedly connected to the drill rig. A blower is fixedly connected to the inside of the first mounting plate. An insertion tube is connected to the lower end of the blower. A second mounting plate is fixedly connected to the outer side of the ring shell. An air tube is fixedly connected to the upper end of the second mounting plate. The insertion tube is slidably connected to the inside of the air tube.

[0009] Preferably, a first air duct and a second air duct are fixedly connected to the outer side of the air tube. The connection position of the second air duct is below that of the first air duct. An inclined tube is fixedly connected to the lower end of the first air duct. The inclined tube slopes downward. An air outlet is formed on the outer side of the insertion tube.

[0010] Preferably, one end of the second air duct communicates with the upper shell. The connection position of the second air duct and the upper shell is below the pressing ring.

[0011] Preferably, the opening of the fixed workbench faces upward, and the fixed workbench is fixedly installed.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention can support the bottom ring through the bottom plate to ensure the stability of the ring shell, and further ensure the stability during the drilling of the drill bit. The ring shell can store the coolant, enabling the coolant to fully contact the drill bit to ensure the heat exchange efficiency of the coolant. The coolant can flow out from the gap between the bottom ring and the drill bit to cool the drilling position, ensuring that the coolant can accurately flow to the drilling area.

[0013] 2. The present invention uses the blower to blow air into the inside of the air tube through the insertion tube. The air will spray out from the inside of the air outlet. At this time, the lower end of the insertion tube blocks the second air duct, and the metal material surface is cleaned through the first air duct to ensure the cleanliness of the metal material surface. As the drill rig drives the blower to move downward, the insertion tube will slide inside the air tube. As the insertion tube slides, the air outlet will communicate with the second air duct. At this time, the insertion tube will block the first air duct. At this time, the air will blow into the inside of the air groove, pushing the pressing ring upward and causing the second spring to contract. At the same time, the injection of gas can accelerate the flow of the coolant, enabling the coolant to wash away the debris generated during drilling. After the drilling is completed and the drill rig moves upward, the drill bit will move out from the inside of the through hole. At this time, the high-pressure gas inside the air groove will squeeze out the coolant inside the ring shell. The second spring can squeeze the pressing ring to ensure the air pressure, enabling the coolant to wash the just-drilled hole, cleaning the hole surface and removing the drilling burrs at the same time. 3. In the present invention, the fixed workbench does not move, and the cost is greatly reduced compared to a machine tool with a moving workbench without affecting the performance of the machine tool. It occupies a smaller area. The heightened X-axis design can effectively prevent coolant from splashing, and it will not cause the transmission mechanism inside the X-axis to run unstably due to coolant splashing, preventing the mechanical parts inside the X-axis from rusting and jamming.

[0024] In this embodiment, the blowing assembly 9 includes a first mounting plate 91 fixedly connected to the drilling rig. A blower 92 is fixedly connected to the inner side of the first mounting plate 91. A plug tube 93 is connected to the lower end of the blower 92.

[0030] Working principle: When the device is in use, the water storage cylinder 85 is connected to the coolant delivery pipeline. When the drill rig moves downward during drilling, it will drive the cooling component 8 to move downward, causing the bottom plate 86 to first press tightly against the metal material. As the drill rig continues to move downward, the drill bit 7 will insert into the inner hole 835 and then pass through the through hole 88 through the lower end of the bottom ring 82 to drill the metal material.

The blower 92 can blow air into the inner side of the air pipe 94 through the insertion pipe 93, and the air will spray out from the inner side of the air outlet 99. At this time, the lower end of the insertion pipe 93 blocks the second air duct 97, and the surface of the metal material is cleaned through the first air duct 96. As the drill rig drives the blower 92 to move downward, the insertion pipe 93 will slide inside the air pipe 94. As the insertion pipe 93 slides, the air outlet 99 will communicate with the second air duct 97. At this time, the insertion pipe 93 will block the first air duct 96, and at this time, the air will blow into the inner side of the air groove 832, pushing the pressing ring 833 upward and causing the second spring 834 to contract. After drilling is completed, when the drill rig moves upward, the drill bit 7 will move out from the inner side of the through hole 88. At this time, the high-pressure gas inside the air groove 832 will squeeze out the cooling liquid inside the ring shell 81, enabling the cooling liquid to wash the just-drilled hole, cleaning the surface of the hole and removing the drilling burrs at the same time.
