DETAILED DESCRIPTION

[0021] The technical scheme in the embodiments of the utility model will be clearly and completely described in combination with the drawings in the embodiments of the utility model, obviously, the described embodiments are only some embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0022] Please refer to Figure 1-3The utility model provides a technical solution: a cooling pipe bending device, including a fixed seat 1, a center wheel 2 is provided at the center of the fixed seat 1, a first bending groove 3 is provided on the upper ring of the center wheel 2, a second bending groove 4 is provided on the lower ring of the center wheel 2, a clamping device 5 is further provided on one side of the center wheel 2, the clamping device 5 includes a first clamping part 6 and a second clamping part 7, the first clamping part 6 includes a first clamping block 8 and a cylinder 9, the first clamping block 8 is installed on the cylinder 9, the second clamping part 7 includes a second clamping block 11 and a weighting block 12, the first The two clamping blocks 11 are fixedly connected to the weighting block 12, the first clamping block 8 is provided with a first clamping groove 13 that cooperates with the first bend groove 3, and the first clamping block 8 is also provided with a second clamping groove 14 that cooperates with the second bend groove 4 in parallel, the second clamping block 11 is provided with a third clamping groove 15 that cooperates with the first clamping groove 13 and has the same radius, the second clamping block 11 is provided with a fourth clamping groove 16 that cooperates with the second clamping groove 14 and has the same radius, and a bending handle 17 is provided on the side of the center wheel 2 away from the clamping device 5.

[0023] Specifically, the width of the first clamping block 8 is equal to the radius of the center wheel 2. Through the above arrangement, when the first clamping block 8 bends the center wheel 2, the limiting effect is better, thereby improving the bending accuracy.

[0024] Specifically, a support base 18 is further provided at the bottom of the fixing base 1. By providing the support base 18, the entire device is more stable during bending, thereby improving the safety of operation.

[0025] Specifically, the bending handle 17 is embedded in the fixing base 1. Through the above arrangement, the bending handle 17 is more stable when in use, and the operator can perform the bending operation more easily. In addition, the embedded design of the bending handle 17 also reduces the space occupied by the device, making the overall structure more compact.

[0026] Specifically, the width of the first bend groove 3 is equal to the width of the first clamping groove 13, and the width of the second bend groove is equal to the width of the second clamping groove 14. Through the above arrangement, the bend and the clamping groove are more closely matched during the bending process, thereby ensuring the shape accuracy and quality of the bend. In addition, the shape of the first clamping groove 13 and the second clamping groove 14 is designed to be semicircular to adapt to the curvature of the bend groove, ensuring good contact between the bend and the clamping block during the bending process, and reducing damage to the surface of the bend.

[0027] In addition, the first clamping part 6 is controlled by the cylinder 9, so that the clamping and loosening actions are faster and more accurate. The use of the cylinder 9 not only improves the operating efficiency, but also reduces the labor intensity of the operator.

[0028] Specifically, an armrest 19 is provided on the side of the fixing base 1 near the bending handle 17. The armrest 19 provides a more stable support for the operator during bending operations, reducing fatigue caused by long-term operation. The design of the armrest 19 not only improves the comfort of operation, but also further enhances the safety during operation.

[0029] Furthermore, the fixing base 1 is provided with an angle mark 10. By providing the angle mark 10, the operator can intuitively understand the bending angle, thereby ensuring the consistency and accuracy of each bend. The provision of the angle mark 10 makes the operation more convenient, and accurate bending work can be completed without additional measuring tools.

[0030] A specific application example of this embodiment is:

[0031] When using this device, the operator first places the cooling tube within the third clamping groove 15 and the fourth clamping groove 16, ensuring that the cooling tube's curvature completely matches that of the third and fourth clamping grooves 15 and 16. The operator then inserts the cooling tube into the first clamping groove 13 and the second clamping groove 14. At this point, the two cooling tubes enter the first and second bend grooves 3 and 4. The operator supports themselves with the handrail 19 and uses the bending handle 17 to bend the tubes. Before bending, the cylinder 9 of the first clamping portion 6 is activated, and the first clamping block 8 quickly moves above the first bend groove 3, tightly fitting the cooling tube to ensure that the cooling tube does not slip or deform during bending.

[0032] As the bending handle 17 rotates further, the center wheel 2 begins to rotate, driving the cooling tube to bend along the arc of the first bend groove 3. Due to the equal width of the first clamping block 8 and the first bend groove 3, and the semicircular design of the first clamping groove 13 and the first bend groove 3, the cooling tube maintains good shape accuracy and quality during the bending process.

[0033] When the required bending angle is reached, the operator can observe the angle mark 10 on the fixing seat 1 to confirm whether the bending angle meets the requirements. If the angle needs to be adjusted, the operator can use the armrest 19 to stabilize the body and adjust the bending handle 17 again until a satisfactory effect is achieved.

[0034] Through the above steps, the present cooling pipe bending device can efficiently and accurately bend cooling pipes, significantly improving production efficiency and product quality. Furthermore, due to its compact design, the weighted block 12 stabilizes the second clamping groove 14, taking up little space and being ideal for use in limited workspaces. Furthermore, the operator does not need to exert excessive physical effort during use, reducing labor intensity and improving operator comfort and safety.
