[0002] In the modern stamping industry, the punch is a key component. During long-term continuous operation, it generates a lot of heat due to the intense friction and deformation with the processed material. Excessive temperature will not only cause the punch material to degrade and its hardness to decrease, thus accelerating the wear and damage of the punch and shortening its service life, but it will also cause thermal deformation of the punch, affecting the dimensional accuracy and surface quality of the stamped parts and increasing the scrap rate. Therefore, effective cooling of the punch is crucial.

[0003] Currently, the connection structure between existing cooling devices and punches is mostly designed with fixed dimensions, which makes it difficult to adapt to the installation requirements of punches of different specifications and models. When enterprises need to replace punches for diversified production, they often need to replace the entire cooling equipment, which increases production costs and equipment maintenance difficulty. On the other hand, some cooling devices lack an effective positioning mechanism during installation, which can easily lead to misalignment or loosening, resulting in poor flow of cooling medium, greatly reducing the cooling effect, and even causing local overheating and damage to the punch due to uneven cooling.

[0004] To address this, a punch cooler adapted to the size and positioning of the punch is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a punch cooler that adapts to the size and positioning of punches.

[0025] 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.

[0026] Please see Figure 1-6 The present invention provides the following technical solution:

[0027] A punch cooler adapted to punch size positioning includes a punch body 1, an inner tube 2 sleeved on the surface of the punch body 1, an outer tube 3 fixedly sleeved on the surface of the inner tube 2 and an installation cavity 4 provided between the outer tube 3 and the inner tube 2, a positioning component 5 provided inside the inner tube 2, and a fixing component 6 fixedly connected to the bottom of the outer tube 3, the fixing component 6 including an installation ring 601.

[0028] The positioning component 5 includes a positioning wedge 501. Mounting holes 502 are provided on both sides of the top surface of the inner tube 2. The positioning wedge 501 is disposed inside the mounting holes 502. A moving rod 503 is fixedly connected to the side of the positioning wedge 501 away from the punch body 1 and the moving rod 503 passes through the outer tube 3. A fixing block 504 is fixedly sleeved on the surface of the moving rod 503. A fastening spring 505 is sleeved on the surface of the moving rod 503. The two ends of the fastening spring 505 are fixedly connected to the fixing block 504 and the inner wall of the inner tube 2, respectively. Positioning grooves 506 that cooperate with the positioning wedge 501 are provided on both sides of the surface of the punch body 1.

[0029] In this embodiment: by setting the positioning component 5, the positioning wedge 501 can cooperate with the positioning groove 506 to lock the punch body 1, restrict the radial movement of the inner tube 2, and ensure that the inner tube 2 and the punch body 1 are installed coaxially. The mounting hole 502 can provide installation space for the positioning wedge 501, restricting the movement trajectory of the positioning wedge 501 so that it can only slide along the axial direction of the mounting hole 502. The moving rod 503 can connect the positioning wedge 501 to the external pulling block 11. By manually pulling or pushing the moving rod 503, the positioning wedge 501 can be moved to the mounting hole of the inner tube 2. The movement of the moving rod 502 allows the positioning wedge 501 to extend or retract. When the positioning wedge 501 is engaged in the positioning groove 506, the fastening spring 505 provides tension to keep the moving rod 503 and the positioning wedge 501 in a tight state, preventing the positioning wedge 501 from loosening due to vibration or other factors. The positioning groove 506 forms a mechanical locking structure by fitting with the inclined surface and end face of the positioning wedge 501, ensuring stability after installation. Thus, the position of the positioning wedge 501 can be manually adjusted by the moving rod 503 to adapt to punch bodies 1 of different sizes or shapes, improving applicability.

[0030] Specifically, such as Figure 3 As shown, the mounting ring 601 is fixedly connected to the bottom of the outer tube 3, and the mounting ring 601 is connected to the inner tube 2.

[0031] Specifically, such as Figure 3 , Figure 5 As shown, the bottom of the mounting ring 601 is provided with an annular groove 602, the surface of the punch body 1 is fixedly sleeved with a connecting ring 603, and the top of the connecting ring 603 is fixedly connected with an annular locking block 604, which works in conjunction with the annular groove 602.

[0032] Specifically, such as Figure 3 , Figure 5 As shown, both sides of the mounting ring 601 are threaded with fastening screws 605, and the annular retaining block 604 has a threaded groove 606 on the side near the fastening screws 605 that is used to cooperate with the fastening screws 605.

[0033] In this embodiment: With the above settings, the mounting ring 601 is the connection hub between the outer tube 3, the inner tube 2, and the punch body 1, which can ensure the stability of the overall structure of the cooler. The annular locking block 604 can cooperate with the annular locking groove 602 to form a mechanical locking structure, so that the punch body 1 can be aligned with the center of the inner tube 2, ensuring the coaxiality of the punch body 1 and the inner tube 2. The fastening screws 605 on both sides of the surface of the mounting ring 601 can be screwed into the threaded grooves 606 of the annular locking block 604, thereby further fixing the two and preventing the punch body 1 from loosening under high-speed stamping or vibration environment, further improving the reliability of the connection.

[0034] Specifically, such as Figure 2 As shown, a spiral tube 7 is fixedly connected inside the mounting cavity 4, and the spiral tube 7 is wound around the surface of the inner tube 2.

[0035] Specifically, such as Figure 2 As shown, extension pipes 8 are fixedly connected to both the top and bottom ends of the spiral tube 7. The extension pipes 8 pass through the outer tube 3 and are connected to the coolant circulation equipment.

[0036] In this embodiment: With the above configuration, the spiral tube 7 is tightly wound around the surface of the inner tube 2, forming a spiral cooling channel. This significantly increases the flow path of the coolant within the spiral tube 7, increasing the contact time with the inner tube 2 and improving heat exchange efficiency. The coolant can absorb the heat transferred by the inner tube 2 and carry it away through circulation, achieving continuous cooling of the punch body 1. The extension tube 8 is the interface between the spiral tube 7 and external equipment, forming the inlet and outlet paths for the coolant. The coolant flows into the spiral tube 7 from one end of the extension tube 8, absorbs heat, and flows out from the other end, achieving circulating cooling. The length and interface design of the extension tube 8 can be adjusted according to the actual equipment layout, allowing the extension tube 8 to flexibly connect to coolant circulation systems of different specifications.

[0037] Specifically, such as Figure 4 , Figure 5 As shown, the inner wall of the inner tube 2 is provided with an alignment groove 9, and the surface of the punch body 1 is fixedly connected with an alignment strip 10, which is used in conjunction with the alignment groove 9.

[0038] Specifically, such as Figure 1 As shown, a pull block 11 is fixedly connected to one end of the moving rod 503 located outside the outer tube 3, and the pull block 11 is made of anti-slip material.

[0039] In this embodiment: With the above settings, when the punch body 1 is installed, the alignment strip 10 can slide along the alignment groove 9 to ensure that the punch body 1 and the inner tube 2 are strictly coaxial, restricting the circumferential rotation of the punch during operation, avoiding uneven cooling or stamping deviation caused by eccentricity. At the same time, the alignment groove 9 and the alignment strip 10 can quickly align the punch body 1 and the inner tube 2, and the operator can achieve accurate alignment without repeatedly adjusting the angle, improving installation efficiency. The surface of the pull block 11 is made of anti-slip material to increase friction. The operator can easily pull or push the moving rod 503 by holding the pull block 11 to adjust the positioning component 5.

[0040] Working principle: First, align the alignment strip 10 on the surface of the punch body 1 with the alignment groove 9 on the inner wall of the inner tube 2 to ensure that the punch body 1 and the inner tube 2 are strictly coaxial. Then, slide the alignment strip 10 along the alignment groove 9 to quickly guide the punch body 1 into the installation position and prevent circumferential rotation. When the punch body 1 is inserted into the inner tube 2, the positioning wedge 501 will be squeezed by the surface of the punch body 1. When the punch body 1 reaches the designated position, the positioning wedge 501 will be locked into the positioning groove 506 under the pulling force of the fastening tension spring 505, providing axial positioning force to prevent the punch body 1 from loosening. At the same time, the connecting ring 60... The annular locking block 604 at the top of the 3 ring will be embedded into the annular locking groove 602 at the bottom of the mounting ring 601. Then, tighten the fastening screw 605 to firmly fix the punch body 1 to the bottom of the outer tube 3. When the punch body 1 is working, the coolant will flow in from the top of the spiral tube 7 through the extension tube 8, forming a spiral flow path. The coolant will absorb the heat transferred by the inner tube 2 to ensure that the punch body 1 maintains a stable temperature during high-temperature stamping and reduce thermal deformation. Then, the coolant will flow out from the extension tube 8 at the bottom of the spiral tube 7 and return to the external coolant circulation equipment for cooling. This is how the cooling is circulated.

[0041] It should be noted that the specific structure, working principle and usage method of the coolant circulation equipment involved in this application are all existing technologies, and therefore are not described in detail in the text.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
