Description

Technical Field

[0001] This utility model relates to the field of vehicle frame manufacturing technology, specifically to a tube bending device for vehicle frame manufacturing. Background Technology

[0002] Currently, in the production process of motorcycle or electric vehicle frames, it is necessary to process the frame tubes into specific angles and curves to meet the geometric shape of the frame design (such as the curvature of the main beam, rear swingarm, shock absorber support, etc.), which requires the use of tube bending equipment.

[0003] Existing pipe bending equipment typically involves operators manually holding the frame tube and placing it into a semi-circular groove on the side of a bending rotating seat. A fixing mechanism on the bending rotating seat then secures the frame tube within the groove, and a stop block on the operating table contacts the periphery of the frame tube before the bending rotating seat rotates to perform the bending operation. However, existing pipe bending equipment makes it difficult to accurately position the frame tube during placement in the semi-circular groove. This can easily lead to misalignment of the bent frame tube, increasing the difficulty of subsequent assembly and hindering adjustments to the frame tube's position in the workshop as needed, thus reducing the practicality of the device. Therefore, to address these technical problems, a pipe bending device for frame production is proposed. Utility Model Content

[0030] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0031] Please see Figures 1 to 4 One embodiment of a tube bending device for vehicle frame production includes a tube bending equipment body 10 and a positioning mechanism. The positioning mechanism includes a mounting bracket 20, a positioning seat 30, and a drive assembly.

[0032] The mounting bracket 20 is mounted on the bending rotating seat 101 in the bending equipment body 10; the positioning seat 30 is slidably mounted on the mounting bracket 20 along the axial direction of the semi-circular straight groove 102 on the periphery of the bending rotating seat 101; the top of the positioning seat 30 is provided with a positioning semi-circular groove 301 that is coaxial with and the same size as the semi-circular straight groove 102; the frame tube 1 can be placed in the semi-circular straight groove 102 and the positioning semi-circular groove 301, and one end can abut against the end of the positioning semi-circular groove 301 away from the semi-circular straight groove 102; the drive assembly is mounted on the mounting bracket 20 and connected to the positioning seat 30 for driving the positioning seat 30 to slide.

[0033] In the above embodiment, after the operator places the frame tube 1 in the semi-circular groove 102, the frame tube 1 can be moved axially along the semi-circular groove 102 to move it into the positioning semi-circular groove 301. When one end of the frame tube 1 abuts against one end of the positioning semi-circular groove 301, the frame tube 1 can be positioned. Positioning the frame tube 1 is convenient, ensuring the accuracy of the bending position of the frame tube 1 and reducing the difficulty of subsequent assembly. Furthermore, by adjusting the drive assembly to drive the positioning seat 30 to slide, the abutment position between the end of the frame tube 1 and the end of the positioning semi-circular groove 301 can be adjusted, thereby facilitating the adjustment of the positioning position of the frame tube 1 according to the requirements and improving the practicality of the device.

[0034] Please see Figure 3 and Figure 4 In one embodiment, the drive assembly includes a screw 40 and a first slider 401; a first groove 201 is provided on one side of the mounting bracket 20, the first slider 401 is slidably disposed in the first groove 201 along the axial direction of the semicircular straight groove 102 and is connected to the positioning seat 30, the screw 40 is axially disposed along the semicircular straight groove 102 and is rotatably disposed in the first groove 201 and threadedly connected to the first slider 401.

[0035] In the above embodiment, the first slider 401 can be driven to move by rotating the screw 40 and engaging with the first slider 401. This makes it easy to move the positioning seat 30. When the screw 40 is stopped, the screw 40 and the first slider 401 can be engaged to fix the positioning seat 30. This makes fixing the positioning seat 30 convenient.

[0036] Specifically, in the above embodiment, the top of the mounting bracket 20 has multiple sets of scale grooves 202, and the top of the positioning seat 30 is provided with an indicator block 304. The positioning seat 30 can slide so that the indicator block 304 corresponds to any scale groove 202. By cooperating with the scale groove 202, the positioning seat 30 can be slid to the designated position quickly and accurately.

[0037] Please see Figure 3 and Figure 4 In one embodiment, the positioning mechanism further includes a pre-tightening assembly, which includes two sets of clamping plates 50 and two sets of first springs 501. The two sets of clamping plates 50 are slidably disposed radially relative to each other along the positioning semicircular groove 301 at the end of the positioning seat 30 near the semicircular groove 102. The two sets of first springs 501 are respectively connected to the positioning seat 30 and the two sets of clamping plates 50 to apply a closing thrust to the two sets of clamping plates 50. The ends of the two sets of clamping plates 50 near the semicircular groove 102 are inclinedly provided with guide plates 502, and the two sets of guide plates 502 cooperate to form a V-shape.

[0038] In the above embodiment, when the frame tube 1 moves axially along the semicircular groove 102 into the positioning semicircular groove 301, the end of the frame tube 1 abuts against the two sets of guide plates 502 and squeezes the two sets of clamping plates 50 away from the movement. At this time, the two sets of first springs 501 are compressed and contracted. The reaction force of the two sets of first springs 501 causes the two sets of clamping plates 50 to apply a certain clamping force to the frame tube 1. Thus, after the frame tube 1 is removed from being held, the frame tube 1 is prevented from falling out of the semicircular groove 102 and the positioning semicircular groove 301 due to gravity. Therefore, when the frame tube 1 is subsequently fixed in the semicircular groove 102, the operator does not need to hold the frame tube 1, thus improving the safety of the device.

[0039] Specifically, in the above embodiment, a second sliding groove 302 is provided at the end of the positioning seat 30 near the semi-circular straight groove 102. A guide rod 303 is provided in the second sliding groove 302. A second slider 503 is provided on each of the two sets of clamping plates 50. The two sets of second sliders 503 are radially slidably disposed in the second sliding groove 302 along the positioning semi-circular groove 301 and are sleeved on the guide rod 303. Two sets of first springs 501 are respectively sleeved on both ends of the guide rod 303, and the two ends respectively abut against the end of the second sliding groove 302 and the second slider 503. Through the cooperation of the second sliding groove 302, the guide rod 303 and the second slider 503, the sliding stability of the two sets of clamping plates 50 can be improved, and the guide rod 303 can guide the extension and retraction of the first springs 501, thereby improving the service life of the first springs 501.

[0040] Please see Figure 4 and Figure 5In one embodiment, the pre-tightening assembly further includes a removal assembly, which includes a push plate 60, a connecting rod 601, a pressure plate 602, and a second spring 603. The connecting rod 601 is axially slidably disposed on the positioning seat 30 along the positioning semicircular groove 301, and a push plate 60 is provided at one end and a pressure plate 602 is provided at the other end. The push plate 60 is located at the end of the positioning semicircular groove 301 away from the semicircular straight groove 102 and is flush with the end face of the positioning semicircular groove 301. The second spring 603 is sleeved on the connecting rod 601, and its two ends abut against the pressure plate 602 and the positioning seat 30, respectively.

[0041] In the above embodiment, when the bending operation is completed and the frame tube 1 needs to be removed, the pressure plate 602 is pressed, and the pressure plate 602 moves, which drives the push plate 60 to move through the connecting rod 601. The push plate 60 moves to abut the end of the frame tube 1, so that the frame tube 1 exits the positioning semicircular groove 301 and the two sets of clamping plates 50, making the removal of the frame tube 1 convenient and effortless.

[0042] The specific implementation method of the above-mentioned tube bending device for chassis production is as follows:

[0043] When the operator places the frame tube 1 into the semi-circular groove 102, and then moves it axially along the semi-circular groove 102 into the positioning semi-circular groove 301, the end of the frame tube 1 abuts against the two sets of guide plates 502, squeezing the two sets of clamping plates 50 away from it. At this time, the two sets of first springs 501 are compressed and contracted. The reaction force of the two sets of first springs 501 causes the two sets of clamping plates 50 to apply a certain clamping force to the frame tube 1. When one end of the frame tube 1 is in contact with one end of the positioning semi-circular groove 301... The frame tube 1 can be positioned upon contact, which is convenient and ensures the accuracy of the bending position of the frame tube 1, reducing the difficulty of subsequent assembly. After positioning, the frame tube 1 can be removed from being held. At this time, the two sets of clamping plates 50 can prevent the frame tube 1 from falling out of the semi-circular straight groove 102 and the positioning semi-circular groove 301 due to gravity. Therefore, when fixing the frame tube 1 in the semi-circular straight groove 102 later, the operator does not need to hold the frame tube 1, improving the safety of the device.

[0044] When it is necessary to change the positioning position of the frame tube 1, the first slider 401 can be driven to move by rotating the screw 40 through the threaded engagement with the first slider 401. The positioning seat 30 is easy to move. When the positioning seat 30 moves to the designated position, the screw 40 is stopped. The screw 40 and the first slider 401 are threaded together to fix the positioning seat 30. Fixing the positioning seat 30 is convenient. The movement of the positioning seat 30 can adjust the contact position between the end of the frame tube 1 and the end of the positioning semicircular groove 301, thereby facilitating the adjustment of the positioning position of the frame tube 1 according to the requirements and improving the practicality of the device.
