Detailed Implementation
[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0026] like Figures 1 to 9 As shown, this utility model discloses a pipe bending device, including: a base 1; a turntable 2, rotatably mounted on the base 1 and capable of being driven to rotate by a drive unit, the turntable 2 being provided with a blank clamping device 21 and a bending die 22; a positioning driver 3, fixed on the base 1, the positioning driver 3 being fixedly provided with a positioning rod 4, the positioning driver 3 being able to drive the positioning rod 4 to move linearly, when the blank 5 is placed into the bending die 22, the positioning rod 4 can be inserted into the blank 5, and with the rotation of the turntable 2, the blank 5 can be made to fit against the bending die 22 for bending.
[0027] Understandably, by setting up the turntable 2, the blank 5 is installed on the bending die 22, and then the positioning rod 4 is inserted into the blank 5. By rotating the turntable 2, the blank 5 is deformed and fits into the bending die 22 to complete the bending process. This has a higher degree of automation, thereby reducing the instability of manual operation and reducing the risk of product defects.
[0028] Preferably, the positioning driver 3 includes a first cylinder 31 and a positioning seat 32 disposed at the end of the first cylinder 31, and the positioning rod 4 is fixed on the positioning seat 32.
[0029] like Figure 3 and Figure 4 As shown, the positioning rod 4 can extend into the blank 5. When the turntable 2 rotates, it can make the blank 5 fit against the bending die 22 and move, thereby causing the blank 5 to bend.
[0030] Preferably, the blank clamping device 21 includes a second cylinder 211 and an abutment block 212, the abutment block 212 being able to cooperate with the bending die 22 to fix the blank 5.
[0031] It is worth mentioning that the extension rod of the second cylinder 211 can be fixed on the turntable. The second cylinder 211 is fixedly connected to the abutment block. When the second cylinder 211 extends or retracts, it can drive the abutment block 212 to move synchronously, thereby achieving contact or separation with the bending die.
[0032] Combination Figure 7 and Figure 8 As shown, preferably, the bending die 22 includes a pipe fitting receiving groove, which includes a straight pipe section 221 and an arc section 223, and a first limiting groove 222 is provided in the straight pipe section 221.
[0033] Combination Figure 5 and Figure 6 As shown, the abutment block 212 is provided with a second limiting groove 214, and the first limiting groove 222 and the second limiting groove 214 cooperate to fix the blank 5.
[0034] The abutment block 212 is provided with a matching groove 216, which cooperates with the straight pipe section 221 to clamp the blank 5.
[0035] like Figure 5 The figure shows the shape of the blank 5 after bending. One end of the blank 5 is provided with a snap ring 51, which extends into the first limiting groove 222 and the second limiting groove 214 for fixation.
[0036] It is worth mentioning that, in this embodiment, the blank 5 can be confined within the bending die 22 by providing a snap-fit ring 51.
[0037] Preferred, combined Figure 6 and Figure 7 As shown, the bending die 22 is provided with a positioning groove 224, and the abutment block 212 is provided with a corresponding positioning protrusion 213.
[0038] Preferred, such as Figure 5 As shown, the turntable 2 is provided with a first slide rail 23, and the abutment block 212 is provided with a first slide groove 215.
[0039] Preferably, the base 1 is provided with a second slide rail 11, and the positioning seat 32 is provided with a second slide groove 33.
[0040] Understandably, by setting up slide rails and grooves, the stability of the components during movement can be improved.
[0041] Preferably, the drive unit includes a servo motor and a reducer.
[0042] The working process of this utility model is as follows:
[0043] Combination Figure 3 As shown, the blank 5 is manually placed in the straight pipe section 221 of the bending die 22, and the snap ring enters the first limiting groove 222. Then the second cylinder 211 is activated, so that the abutment block 212 approaches the bending die 22, so that the positioning protrusion 213 enters the positioning groove 224, and at the same time the snap ring 51 enters the second limiting groove 214.
[0044] Then, the first cylinder 31 is extended to allow the positioning rod 4 to extend into the blank 5. The diameter of the positioning rod 4 is smaller than the inner diameter of the blank 5.
[0045] Start the servo motor, which drives the turntable 2 to rotate clockwise through the reducer, so that the blank 5 is bent into contact with the bending die 22.
[0046] In this embodiment, after the turntable 2 rotates 90 degrees, the bending is completed, and then the first cylinder 31 is retracted, causing the positioning rod 4 to exit the blank 5, thus completing the bending process of the blank 5.
[0047] Then rotate turntable 2 counterclockwise to retract the second cylinder 211, and manually remove the finished product.
[0048] By repeating the above steps, the blank 5 can be bent quickly, which can effectively improve production efficiency and make the product quality more stable.
[0049] 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.
