[0023] The present utility model will be described in detail below with reference to the drawings and in conjunction with embodiments.

[0024] As shown in the figure, a blanking device for the production of threaded pipes includes a conveying frame 1. A plurality of conveying rollers 15 are provided on the upper side of the conveying frame 1. A vertically movable lifting rod 2 is horizontally provided in front of the conveying frame 1. A plurality of wedge-shaped blocks 3 are fixedly connected to the lifting rod 2 in a scattered manner. The plurality of wedge-shaped blocks 3 and the plurality of conveying rollers 15 are arranged in a crosswise manner. A guide plate 5 is inclined downward in front of the lifting rod 2. The guide plate 5 and the conveying frame 1 are hung together by a hook 7. In this embodiment, the device is installed at the end of the threaded pipe production line and is aligned with the end of the conveying mechanism on the production line. After the threaded pipes are produced on the production line, the conveying mechanism conveys them to the conveying frame 1 of this device and continues to convey them forward through the conveying rollers 15. When the threaded pipes completely reach this device, the lifting rod 2 moves upward, driving the wedge-shaped blocks 3 to move upward, lifting the threaded pipes to separate them from the conveying rollers 15. The threaded pipes roll forward under the action of the wedge-shaped blocks 3 onto the guide plate 5 and are then guided by the guide plate 5 to reach the ground.

[0025] The conveying frame 1 further includes columns 11 and connecting beams 12. The two connecting beams 12 are arranged side by side, and columns 11 are vertically and fixedly connected to both ends of the bottom of each connecting beam 12. A plurality of bearing seats 13 are evenly arranged on the upper side of the front connecting beam 12, and a connecting plate 14 is fixedly connected to the upper side of the rear connecting beam 12. The conveying roller 15 is connected between the bearing seat 13 and the connecting plate 14. In this embodiment, the conveying roller 15 is connected to the connecting plate 14 and the bearing seat 13 through bearings, and a motor is fixedly connected to the rear side of the connecting plate 14. The end of each conveying roller 15 passes through the connecting plate 14 and is fixedly connected with a sprocket. The plurality of conveying rollers 15 are driven by cooperation of sprockets, chains and the driving wheel fixedly connected to the output shaft of the motor. This is a conventional technical means in the art, and the main innovation point of this application does not lie here. Therefore, the specific connection structure is not described in detail here.

[0026] On the front side of the two columns 11 on the front side of the conveying frame 1, a horizontally arranged mounting plate 16 is fixedly connected. At both ends of the bottom of the lifting rod 2, lifting units 4 are vertically and fixedly connected, and the bottoms of the lifting units 4 are fixedly connected to the mounting plate 16. In this embodiment, the lifting unit 4 is a hydraulic cylinder.

[0027] A first reinforcing rib 8 is fixedly connected between the bottom of the mounting plate 16 and each corresponding column 11 to increase the supporting strength of the mounting plate 16.

[0028] Support columns 6 are vertically and fixedly connected to the four corners of the bottom of the guide plate 5, and inverted L-shaped hooks 7 are fixedly connected to the rear sides of the two support columns 6 close to the mounting plate 16. Through holes are opened on the mounting plate 16 corresponding to each hook 7, and the vertical part at the end of the hook 7 passes downward through the through hole. In this embodiment, the support column 6 on the rear side of the guide plate 5 is hung on the mounting plate 16 through the hook 7, so that the guide plate 5 and the conveying frame 1 can be positioned, and the guide plate 5 is prevented from moving forward or even moving away from the lifting rod 2 when being acted on by the threaded pipe.

[0029] A plurality of arc-shaped through grooves 51 are evenly arranged on the upper side surface of the guide plate 5, which play a role in hindering the threaded pipe, preventing the threaded pipe from rolling faster and faster and generating a large impact force, and causing a large impact when leaving the guide plate 5.

[0030] The wedge block 3 is located above the connecting beam 12, and when the wedge block 3 is in the lowest position, the highest point position of the rear end of the wedge block 3 is lower than the highest point position of the conveying roller 15 at the same cross section, ensuring that the wedge block 3 does not hinder the threaded pipe during the conveying process.

[0031] A second reinforcing rib 9 is fixedly connected between the bottom of each wedge block 3 and the lifting rod 2 to increase the supporting strength of the wedge block 3.

[0032] The working process of this embodiment is as follows:

[0033] The device is installed at the end of the threaded pipe production line and aligned with the end of the conveying mechanism on the production line. After the threaded pipe is produced on the production line, the conveying mechanism transports it to the conveying rack 1 of the device and continues to transport it forward through the conveying roller 15. When the threaded pipe completely reaches the device, the lifting unit 4 is activated to drive the lifting rod 2 to move upward, thereby driving the wedge block 3 to move upward, lifting the threaded pipe to separate it from the conveying roller 15. The threaded pipe rolls forward under the action of the wedge block 3 and falls onto the guide plate 5, and then is guided by the guide plate 5 to reach the ground; then the lifting unit 4 is used to drive the lifting rod 2 to move downward to reset it.

[0034] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
