[0026] The following will be described in more detail with reference to the schematic diagram of the tube bending machine of the utility model, wherein the preferred embodiment of the utility model is shown, and it should be understood that the utility model described herein can be modified by a person skilled in the art, while still achieving the advantageous effects of the utility model. Therefore, the following description should be understood as being widely known to a person skilled in the art, and not as a limitation to the utility model.

[0027] The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description and claims. It should be noted that the accompanying drawings are in very simplified form and in non-precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0028] like Figure 1 and Figure 2 As shown, the embodiment of the utility model provides a progressive feeding mechanism for a pipe bending machine, comprising a feeding track 1, a feeding table 2 and a driving member.

[0029] Specifically, the feed track 1 is laid on the feed side of the bending machine.

[0030] The feeding platform 2 is slidably mounted on the feeding track 1 , and a fixing member 3 for fixing the pipe to be fed is movably provided on the feeding platform 2 .

[0031] The driving member is fixedly arranged on the feeding side of the bending machine, the driving member is transmission-connected to the feeding table 2 , and the driving member is used to drive the feeding table 2 to slide along the length direction of the feeding track 1 .

[0032] In this embodiment, when the pipe needs to be fed into the bending machine, the pipe is placed on the feeding table 2, and the fixing member 3 is used to position and fix the pipe. Finally, the driving member drives the feeding table 2 to move along the feeding track 1 until the feeding is completed. During the feeding process of the pipe, the fixing member 3 positions and fixes the pipe, which can effectively ensure the stability of the pipe feeding.

[0033] Furthermore, the feeding platform 2 includes a base 4 and a bearing seat 5 .

[0034] Specifically, the base 4 is slidably disposed on the feeding track 1 .

[0035] The bearing seat 5 is detachably arranged on the base 4, and the bearing seat 5 is used for bearing and supporting the pipe to be fed.

[0036] In this embodiment, at least two positioning columns 6 are provided on the base 4, and positioning holes 7 matching the positioning columns 6 are provided on the bearing seat 5. The base 4 and the bearing seat 5 are detachably connected through the cooperation between the positioning columns 6 and the positioning holes 7. In practical applications, different bearing seats 5 can be selected according to the feed height.

[0037] Among them, a V-shaped positioning groove 8 is arranged on the upper surface of the bearing seat 5, and the inner side wall of the V-shaped positioning groove 8 can support pipes of different diameters, which can not only reduce the shaking of the pipe in the V-shaped positioning groove 8, but also reduce the risk of the pipe slipping out of the V-shaped positioning groove 8.

[0038] When installing and removing the bearing seat 5, in order to prevent the hands from being pinched between the bearing seat 5 and the base 4, two anti-pinch grooves 9 are symmetrically arranged on the side of the bearing seat 5. When the operator carries the bearing seat 5, he can put his hands into the anti-pinch grooves 9 for carrying.

[0039] Furthermore, the fixing member 3 is rotatably mounted on the bearing seat 5, and a pushing bar 10 is provided on the end surface of the fixing member 3 which is away from the feeding direction of the pipe, and the pushing bar 10 is used to push the feeding of the pipe.

[0040] Specifically, after the pipe is placed in the V-shaped positioning groove 8, the fixing member 3 is rotated so that the other end of the fixing member 3 is in contact with the supporting seat 5. At this time, the pushing bar 10 is located on the outside of the end of the material pipe away from the feeding direction. During the movement of the feeding platform 2, the pushing bar 10 drives the pipe to move together to ensure smooth feeding of the pipe.

[0041] In a specific embodiment, an adsorption magnetic sheet 11 is provided at one end of the fixing member 3 away from the rotating connection, and the adsorption magnetic sheet 11 is magnetically adsorbed to the base 4. During the closing process of the fixing member 3, the adsorption magnetic sheet 11 is used to adsorb the fixing member 3 on the bearing seat 5, which effectively reduces the risk of the fixing member 3 being unable to feed due to vibration and flipping.

[0042] Furthermore, the driving member includes a driving rack 12 , a travel motor 13 and a driving gear 14 .

[0043] Specifically, the driving rack 12 is fixedly arranged on the feeding side.

[0044] The travel motor 13 is fixedly mounted on the base 4 .

[0045] The driving gear 14 is fixedly mounted on the output shaft of the travel motor 13 , and the driving gear 14 is meshedly connected with the driving rack 12 .

[0046] In this embodiment, when the driving member needs to drive the feeding table 2 to feed, the traveling motor 13 works, the traveling motor 13 drives the driving gear 14 to rotate, and the driving gear 14 drives the feeding table 2 to move along the driving rack 12, thereby completing the feeding operation. The forward and backward movement of the feeding table 2 is controlled by the forward or reverse rotation of the traveling motor 13.

[0047] In a specific embodiment, the traveling motor 13 is a stepper motor. A stepper motor is a discrete value control motor that converts an electric pulse excitation signal into a corresponding angular displacement or linear displacement. This motor moves one step each time an electric pulse is input, so it is also called a pulse motor. The driving power supply of the stepper motor is composed of a variable frequency pulse signal source, a pulse distributor and a pulse amplifier, and the driving power supply provides a pulse current to the motor winding. The operating performance of the stepper motor is determined by the good coordination between the motor and the driving power supply.

[0048] In this embodiment, the traveling motor 13 is a stepping motor, which can accurately advance the feeding table 2, thereby ensuring the bending accuracy of the bending machine.

[0050] The utility model can progressively feed pipes with different outer diameters, and at the same time, during the progressive feeding process of the pipes, can ensure stable feeding of the pipes, greatly improves the stability of the pipe feeding, and has the characteristics of simple structure and convenient operation.

[0051] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
