Description

Technical Field

[0001] This invention relates to the field of pipe bending machine technology, specifically to a pipe bending machine for electric vehicle battery cooling pipes and its processing method. Background Technology

[0002] Electric vehicles require a large amount of electricity to operate. Due to the high current and the internal resistance of the battery, prolonged operation inevitably generates a significant amount of heat, causing the battery temperature to rise. Excessive battery temperature can affect battery life and, in extreme cases, may even lead to explosion. Therefore, cooling is necessary during battery operation, leading to the development of battery cooling pipes. However, because the battery is located inside the vehicle, space is limited, restricting the routing of the cooling pipes. This results in poor manufacturability and inconvenience in processing, even while maintaining performance. Such pipe fittings cannot be processed in a single operation using ordinary pipe bending machines; additional methods and human assistance are required to complete the processing on general-purpose machines.

[0003] Cooling pipes are a crucial part of the battery cooling system, essential for safe battery operation and ensuring battery lifespan. They require high performance, and due to their unique spatial configuration, ordinary pipe bending machines cannot process them, nor can they meet the required geometric tolerances.

[0020] To better achieve the objectives of this invention, this invention also provides a processing method for an electric vehicle battery cooling pipe bending machine, comprising the following steps:

[0021] Step 1: During operation, the workpiece is placed on the irregular support seat of the clamping component of the mold assembly by a manual operator or an external robotic arm. The position of the workpiece is adjusted so that one end of the workpiece is located between the hook-shaped clamping block and the fixed clamping block, and the side wall of the workpiece contacts the limiting groove on the lower mold of the mold closing assembly. Then, the output end of the second clamping cylinder extends, driving the first movable clamping block to slide along the first clamping slide rail. The first movable clamping block cooperates with the irregular support seat to clamp the workpiece. The output end of the first clamping cylinder retracts, driving the hook-shaped clamping block to cooperate with the fixed clamping block to clamp the workpiece. Then, the output end of the air booster cylinder drives the upper mold to move downward and cooperate with the lower mold. The output end of the third clamping cylinder extends, driving the second movable clamping block to slide along the second clamping slide rail, thereby pressing the workpiece onto the limiting groove and fixing the workpiece.

[0022] Step 2: The output end of the first cylinder of the first bending component of the pipe bending assembly drives the first slider to slide along the first slide rail. During the sliding process, the first pressure bending plate is brought closer to the workpiece. After the first pressure bending plate touches the workpiece, it rotates along the first slider through the hinge seat, so that the first pressure bending plate fits against the surface of the workpiece and continues to squeeze and bend the workpiece until the first pressure bending plate presses the workpiece tightly against the limiting groove.

[0023] Step 3: The output end of the third cylinder of the avoidance component extends, causing the third slider to move upward along the third slide rail. Then, the output end of the fourth cylinder extends, causing the second bending plate to move along the fourth slide rail, thereby moving the second bending plate to the designated position. The second cylinder causes the second slider to slide along the second slide rail, thereby causing the second bending plate to move towards the workpiece and fit against the workpiece. Then, the output end of the bending cylinder retracts, causing the rotating support plate to rotate around the central axis, so that the second bending plate pushes the workpiece to bend until the workpiece is tightly attached to the limiting groove, completing the bending.

[0024] Step 4: After bending is completed, the output end of the air booster cylinder drives the upper mold to move upward, the upper mold and the lower mold separate, the device resets, and the workpiece is removed manually or by an external robot.

[0025] The present invention has the following technical effects:

[0026] 1. The present invention separates the upper and lower molds of the mold clamping assembly, which facilitates the clamping and positioning of the workpiece during clamping and makes it easy to remove the workpiece after bending; the workpiece is clamped by the hook-shaped clamping block, the first movable clamping block and the second movable clamping block of the clamping assembly, which facilitates the positioning of the workpiece.

[0027] 2. This invention allows for the rapid and convenient bending of designated parts of a workpiece by sequentially pushing the first slider and rotating the rotary support plate, without the need for manual adjustment;

[0028] 3. The present invention uses a clamping assembly and a fourth cylinder to move the second bending plate, which can avoid the workpiece when the first bending assembly is bending, thus preventing the workpiece from colliding with the device and causing damage to the workpiece or the device.

[0067] Step 2: The output end of the first cylinder 411 of the first bending component 41 of the pipe bending assembly 4 drives the first slider 413 to slide along the first slide rail 412. During the sliding process, the first pressure bending plate 415 is driven to approach the workpiece. After the first pressure bending plate 415 touches the workpiece, it rotates along the first slider 413 through the hinge seat 414, so that the first pressure bending plate 415 fits against the surface of the workpiece and continues to squeeze and bend the workpiece until the first pressure bending plate 415 presses the workpiece tightly against the limiting groove 313.

[0068] Step 3: The output end of the third cylinder 52 of the avoidance component 5 extends, causing the third slider 54 to move upward along the third slide rail 53. Then, the output end of the fourth cylinder 55 extends, causing the second bending plate 426 to move along the fourth slide rail 56, thereby moving the second bending plate 426 to the designated position. The second cylinder 423 causes the second slider 425 to slide along the second slide rail 424, thereby causing the second bending plate 426 to move towards the workpiece and fit against the workpiece. Then, the output end of the bending cylinder 428 retracts, causing the rotating support plate 422 to rotate around the central axis 421, so that the second bending plate 426 pushes the workpiece to bend until the workpiece is tightly attached to the limiting groove 313, completing the bending.

[0069] Step 4: After bending is completed, the output end of the air booster cylinder 2 drives the upper mold 311 to move upward, the upper mold 311 and the lower mold 312 separate, the device is reset, and the workpiece is taken out manually or by an external robot.
