Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a die water cooling circulation structure. Background Art

[0002] In the process of sheet metal stamping, the sheet metal is often placed on a die, and then a punch is used to stamp the sheet metal to cause plastic deformation of the sheet metal. However, a large amount of heat is generated in the process of the punch and the die continuously squeezing the sheet metal, which causes the material and the mold to heat up. Since the die and the punch are closely matched, the generated heat is difficult to dissipate. The existing cooling operation is often to spray coolant directly on the surface of the punch. This method certainly has a certain cooling effect, but the coolant is highly contaminated and often needs to be filtered before it can be recycled. This undoubtedly increases production costs and reduces the frequency of recycling of the coolant. Utility Model Content

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] like Figure 1-4As shown, a mold water cooling circulation structure includes a punch body 1, which is the main structure of the device. After the device is fixed to the punching machine, the punching machine is used to drive the punch body 1 to move so as to realize the punching of the plate. A cooling cavity 2 is provided inside the punch body 1, and the cooling cavity 2 is used for the circulation of coolant. The cooling cavity 2 has a large area, which can effectively improve the heat conduction efficiency between the coolant and the punch body 1, and the heat absorption efficiency is high. An embedding groove 3 communicating with the cooling cavity 2 is provided on the top of the punch body 1, and an adapter 4 is sleeved inside the embedding groove 3. A confluence cavity 5 is provided at the bottom of the adapter 4, and a stainless steel cooling pipe 6 matching the cooling cavity 2 is sleeved inside the confluence cavity 5. A water inlet 7 communicating with the confluence cavity 5 is provided on one side of the adapter 4. A first sealing ring groove 8 and a second sealing ring groove 9 are spaced apart on the outer side of the end. A water cooling hole 10 matching the water inlet hole 7 is formed on the inner wall of the first sealing ring groove 8. The water cooling hole 10 is used to connect an external coolant delivery pipeline to transport the coolant. A reflux hole 11 communicating with the cooling chamber 2 is formed on the inner wall of the second sealing ring groove 9. The reflux hole 11 is used to connect an external coolant reflux pipeline to recover the coolant. When the device is in use, the coolant enters the confluence chamber 5 through the water cooling hole 10 and the water inlet hole 7, and then enters the stainless steel cooling pipe 6 through the confluence chamber 5. Finally, the coolant is input into the cooling chamber 2 through the stainless steel cooling pipe 6 to absorb heat and cool the punch rod body 1. The coolant that has absorbed the heat flows out through the reflux hole 11 communicating with the cooling chamber 2 to achieve recovery.

[0020] In this embodiment, specifically, the radius of the embedded groove 3 is larger than the cooling cavity 2, which facilitates the installation of the adapter 4 and ensures the stability of the adapter 4 during installation. The input end of the stainless steel cooling pipe 6 is located below the water inlet hole 7, ensuring that the coolant can smoothly enter the stainless steel cooling pipe 6. The first sealing ring groove 8 is located above the second sealing ring groove 9.

[0021] In the present embodiment, specifically, positioning pin holes 12 are symmetrically opened on the outer side of the bottom end of the adapter 4, and the positioning pin holes 12 are used to install positioning bolts to fix the stainless steel cooling pipe 6, so as to avoid the stainless steel cooling pipe 6 from slipping during use, thereby ensuring the stability of the stainless steel cooling pipe 6 during use.

[0022] In the present embodiment, specifically, an embedded sealing ring groove 13 is provided around the outer side of the top end of the adapter 4, and the embedded sealing ring groove 13 is used to install an O-ring to form a radial seal between the adapter 4 and the embedded groove 3, thereby ensuring the sealing when the coolant enters the cooling chamber 2 and preventing leakage from the embedded groove 3.

[0023] In this embodiment, specifically, a connection groove 14 is provided on the top of the adapter 4, and the connection groove 14 is used for connection and fixation with the stamping drive mechanism.

[0024] The working principle of the utility model is as follows: when the device is in use, it is connected to the stamping drive mechanism through the connecting groove 14 provided on the adapter 4. When the punching machine drives the punch rod body 1 to punch the plate, the coolant enters the confluence chamber 5 from the water cooling hole 10 and the water inlet hole 7, and then flows into the stainless steel cooling pipe 6 through the confluence chamber 5. Finally, the coolant is input into the cooling chamber 2 through the stainless steel cooling pipe 6 to absorb heat and cool the punch rod body 1. The coolant that has absorbed the heat flows out through the reflux hole 11 that is connected to the cooling chamber 2, thereby cooling the punch rod body 1.

[0025] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
