[0024] To make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments of the present utility model and the features in the embodiments can be combined with each other.

[0025] Some embodiments of the present utility model will be described below with reference to the accompanying drawings. Embodiment 1

[0026] Combined with Figures 1-5 As shown, this embodiment provides a stainless steel pipe bending and forming machine, including: a main body mechanism 100 and a feeding mechanism 200.

[0027] The main body mechanism 100 includes a base 110, a positive conical bending wheel 120 rotatably installed at the top of the base 110, a rotating seat 130 rotatably sleeved on the base 110, an inverted conical roller 140 rotatably arranged at the top of the rotating seat 130, a driving member 150 installed on one side of the base 110, and a toothed belt 160 with one end sleeved on the rotating seat 130 and the other end sleeved on the driving member 150.

[0028] Among them, the base 110 is used to install other components. The positive conical bending wheel 120 is rotatably arranged at the top of the base 110, and a plurality of annular first bending grooves 121 are arranged in an array on the surface. The bending wheel is designed as a positive cone. When bending steel pipes with different radii, only need to embed the steel pipe into the first bending grooves 121 at different positions on the positive conical bending wheel 120. The bending radius of the first bending groove 121 near the top of the positive conical bending wheel 120 is smaller, and conversely, the bending radius of the first bending groove 121 near the bottom is larger, effectively avoiding the trouble of replacing the bending wheel.

[0029] The rotating seat 130 is used to mount the inverted conical roller 140 and drive the inverted conical roller 140 to rotate, so as to realize the bending of the steel pipe. The rotating seat 130 includes a rectangular plate 131 rotatably sleeved on the base 110 and a toothed ring 132 fixed to the bottom end of the rectangular plate 131. An annular protrusion 111 is arranged on the outer side of the top end of the base 110. A circular hole 231 is formed on one side of the rotating seat 130. A ring groove is arranged on the inner wall of the circular hole 231. The annular protrusion 111 is rotatably fitted in the annular groove 1311 to ensure the stability of the rectangular plate 131 during rotation.

[0030] The inverted conical roller 140 is rotatably mounted on the rectangular plate 131 and abuts against the positive conical bending wheel 120. A plurality of annular second bending grooves 141 are arranged in an array on the surface of the inverted conical roller 140. When the inverted conical roller 140 rotates around the positive conical bending wheel 120, the steel pipe fitted between the first bending groove 121 and the second bending groove 141 can be bent.

[0031] The driving member 150 is used to drive the rotating seat 130 to rotate, and includes a motor 151 mounted on one side of the base 110 and a gear 152 fixed to the shaft of the motor 151. One end of the toothed belt 160 is meshed on the outside of the gear 152, and the other end is meshed on the outside of the toothed ring 132. When the motor 151 is started, it drives the gear 152 to rotate. The rotation of the gear 152 drives the toothed ring 132 to rotate through the toothed belt 160. The rotation of the toothed ring 132 drives the rectangular plate 131 to rotate, and the rotation of the rectangular plate 131 drives the inverted conical roller 140 to rotate to bend the steel pipe.

[0032] The feeding mechanism 200 is used to automatically feed the steel pipe between the positive conical bending wheel 120 and the inverted conical roller 140, and includes a bracket 210 fixed to one side of the base 110, a plurality of first electric telescopic rods 220 mounted on the bracket 210, a material rack 230 fixed to the top end of the first electric telescopic rod 220, and a pushing member 240 mounted at the bottom end of the material rack 230 and extending into the material rack 230.

[0033] The bracket 210 is used to fix the first electric telescopic rod 220 to ensure the stability of the first electric telescopic rod 220. The first electric telescopic rod 220 is used to mount the material rack 230 and drive the material rack 230 to move up and down, so as to facilitate feeding the steel pipe into the first bending groove 121 at different positions on the positive conical bending wheel 120.

[0034] The rack 230 is used for temporarily placing the steel pipes to be bent. A round hole 231 is opened on one side of the rack 230 for sending out the steel pipes. The pushing member 240 is used for pushing out the lowermost steel pipe in the rack 230, and includes a second electric telescopic rod 242 installed at the bottom end of the rack 230 and a push rod 241 with one end extending into the inner cavity of the rack 230 and the other end fixedly connected to the end of the second electric telescopic rod 242. When the second electric telescopic rod 242 is started, it drives the push rod 241 to move, and the push rod 241 moves to push the steel pipe out of the rack 230, so that it enters between the positive conical bending wheel 120 and the inverted conical roller 140.

[0035] The working principle and usage process of the present utility model: When in use, the steel pipes to be bent are placed into the rack 230. According to the requirements, different first bending grooves 121 at different positions on the positive conical bending wheel 120 are selected. After completion, the first electric telescopic rod 220 is started to drive the rack 230 to move up and down, so that the round hole 231 at one end of the rack 230 corresponds to the first bending groove 121 on the selected positive conical bending wheel 120. Then the second electric telescopic rod 242 is started to drive the push rod 241 to move, and the lowermost steel pipe in the rack 230 is pushed outwards. The steel pipe passes through the first bending groove 121 on the positive conical bending wheel 120 and the corresponding second bending groove 141 on the inverted conical roller 140. At this time, the motor 151 is started to drive the gear 152 to rotate. The rotation of the gear 152 drives the toothed ring 132 to rotate through the toothed belt 160. The rotation of the toothed ring 132 drives the rectangular plate 131 to rotate. The rotation of the rectangular plate 131 drives the inverted conical roller 140 to rotate to bend the steel pipe. After completion, the steel pipe is taken out, and then the above process is repeated.

[0036] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the claims and their equivalents.
