Technical Field

[0001] The invention relates to metal pipe processing equipment, in particular to a pipe bending device for heater metal pipes. Background Art

[0002] Pipe heater is a device that heats the fluid in the pipe. It is usually installed before the material equipment to directly heat the material, so that it can be circulated and heated at high temperature, and finally achieve the purpose of saving energy. Pipes need to be bent during the processing to facilitate the butt connection of pipes. Conventional pipe bending is done manually, which has low bending efficiency and cannot guarantee the bending accuracy, and cannot meet production needs.

[0003] In view of the above-mentioned defects, the designer actively conducts research and innovation in order to create a tube bending device for a heater metal tube to make it more valuable for industrial use. Summary of the invention

[0004] In order to solve the above technical problems, the object of the present invention is to provide a tube bending device for a heater metal tube.

[0005] The present invention discloses a tube bending device for a heater metal tube. The ends of the device are two sets of metal tube bending parts with the same structure. The metal tube bending parts perform a bending operation on the metal tube. The manipulator on the transfer part grabs the bent metal tube and then transfers the metal tube to a conveying rack to complete the discharge of the metal tube. The metal pipe bending part includes a bending base in contact with the foundation, a stand is fixed on the bending base, a bending die is installed on the top of the stand, and a liftable bending pusher is provided under the stand, and the bending pusher is powered by a bending cylinder.

[0006] This heater metal tube bending device drives the tube bending pusher to move through the tube bending cylinder. The tube bending pusher cooperates with the bending die to complete the bending operation of the metal tube. The bent metal tube is grasped and transferred by a robot and transferred to a conveyor rack for unloading, which is convenient for unloading. The entire operation is mechanized, which improves production efficiency and ensures the accuracy of the bending.

[0007] Furthermore, a card plate with a groove is fixed to the upper end of the bending die head, and the card plate slides into the mounting seat. Baffles are movably installed on both ends of the mounting seat through shafts. The baffle is semicircular and has a notch at the upper end for the card plate to detach.

[0008] The bending die head is a detachable structure, and different die heads can be selected for installation according to the bending radius, thereby improving the application range of the device.

[0009] Furthermore, the pipe bending push head includes a lower support fixedly mounted on the bending base and a push plate connected to the pipe bending cylinder. The push plate has three connecting feet, which are movably connected to the pipe bending cylinder, the lower support and the upper support through an axis and a connecting rod respectively. A "V"-shaped bracket is fixed on the upper support.

[0010] The pipe bending pusher head moves upward after being pushed by the pipe bending cylinder and cooperates with the bending die head to perform the pipe bending operation.

[0011] Furthermore, there are cross bars between the brackets for supporting the metal pipes, and there are multiple guide wheels on both sides of the brackets that are clamped on the outside of the stand.

[0012] The guide wheels on both sides of the bracket of the bending pipe push head are clamped on both sides of the vertical frame to provide guidance for the movement of the bending pipe push.

[0013] Furthermore, a cylinder slide is fixed on the bending base, the cylinder slide is movably installed with the bending cylinder through a slider, a rotatable screw is installed in the cylinder slide, the slider is sleeved on the screw, and a rotating handle is provided at the tail end of the screw.

[0014] The relative position of the pipe bending cylinder is adjustable. The position of the pipe bending cylinder is determined according to the diameter of the metal pipe to be bent and the stroke of the pipe bending work. The bending operation of metal pipes with different diameters can be satisfied in an adjustable manner.

[0015] Furthermore, the transfer part includes a transfer base, above which are two parallel transfer rails, a manipulator mounting plate is movably mounted on the transfer rails by means of a slider, a manipulator is mounted above the manipulator mounting plate, a rack is fixed above one side of the transfer base, a transfer motor is fixed on the manipulator mounting plate, and a drive gear is installed on the output shaft of the transfer motor after passing through the manipulator mounting plate, and the drive gear is meshed with the rack.

[0016] The transfer motor on the transfer part provides power for the movement of the manipulator, so that the position of the manipulator can be moved on the transfer base, which is convenient for its movement and convenient for grabbing the bent metal pipe. The bent metal pipe is grabbed and placed on the conveyor rack to complete the metal pipe discharge transfer.

[0017] Furthermore, the conveying racks are divided into four groups and are arranged parallel to each other.

[0018] There are four groups of conveying racks, which are grouped in pairs and correspond to a bending part of the metal pipe respectively. Two groups of conveying racks are feeding conveying racks, and the other two groups are discharging conveying racks, which are convenient for the transportation of metal pipes.

[0019] Through the above scheme, the present invention has at least the following advantages: this heater metal tube bending device provides a loading and unloading conveyor frame for the metal tube bending part, and the corresponding metal tube is transferred to / from the metal tube bending part by a robot. The entire processing process is completed by the machine, avoiding manual operation, improving production efficiency while ensuring the uniformity of bending to meet production needs.

See also Figure 1 and Figure 2 This heater metal pipe bending device includes two side-by-side metal pipe bending parts. The conveying frame 1 includes loading and unloading functions, which can transport the pipe to the position of the transfer part. The loaded metal pipe is grabbed by the manipulator of the transfer part, and then placed in the metal pipe bending part for bending operation. After the bending is completed, the metal pipe is removed from the metal pipe bending part and transferred to the conveying frame 1 for unloading, so as to remove the bent metal pipe.

[0025] The bending part of the metal pipe is fixedly installed on the foundation through a bending base 2. The bending base 2 has a vertical frame 3. A bending push head 5 installed on the inner side of the frame 3 is used in conjunction with a bending die head 4 at the top of the frame 3. The bending die head 4 has a concave groove for facilitating the positioning of the metal pipe. The bending cylinder 6 is used to drive the bending push head 5 to move, drive the bending push head 5 to move upward, and cooperate with the bending die head 4 to complete the bending operation of the metal pipe.

[0026] See also Figure 3 and Figure 4 The clamping plate 7 of the bending die head 4 can slide into the mounting seat 8, and the mounting seat 8 is fixedly connected to the top horizontal plate of the stand 3. After the clamping plate 7 is turned in, the baffle 9 is rotated, and the baffle 9 is stuck at the outer end of the clamping plate 7 to complete the blocking and prevent the clamping plate 7 from sliding out of the mounting seat 8. This installation method makes the bending die head 4 replaceable. According to production requirements, different bending die heads 4 can be selected for bending operations of different metal pipes.

[0027] See also Figure 5 The lower support 10 of the bending push plate 5 is installed on the bending base 2, the upper support 12 is movably connected with the bracket 13, the lower support 10, the upper support 12 and the bending cylinder 6 are movably installed with the three connecting feet of the push plate 11 through the connecting rod and the shaft, so that when the bending cylinder 6 is working, it can drive the bracket 13 to perform the lifting operation, the bending operation is performed when it rises, and it is used for unloading the bent metal pipe when it descends.

[0028] The cross bar 14 in the middle of the bracket 13 is used to support the metal pipe. At the same time, there is a guide wheel 15 on the outside of the bracket 13 and is clamped on the outside of the stand 3 to provide guidance for the bracket 13 to move up and down.

See also Figure 1 The conveyor frame 1 has four groups, two of which are used for loading and the other two are used for unloading. Combined with the two groups of metal pipe bending parts, the purpose of synchronous production of two groups of metal pipes is achieved.

[0031] The working principle of the present invention is as follows: When this heater metal tube bending device is working, the four groups of conveyor racks 1 are grouped in twos, two for loading and two for unloading. The conveyor racks 1 for loading and unloading form a group. When the metal tube is conveyed to the vicinity of the robot arm, the robot arm grabs the metal tube and moves it to the metal tube bending part, and bends the metal tube. The bent metal tube is grabbed by the robot arm and moved to the conveyor rack 1 for unloading, thereby completing the processing of the metal tube.
