A second support block 177 is provided at one end, and the second support block 177 corresponds to the first support block 173. The second support block 177 cooperates with the first support block 173 to support the steel pipe so that the steel pipe is aligned with the mold base body 501, which is convenient for subsequent processing. Rotating the adjusting screw 176 can change the position of the movable tail stock 174, thereby changing the distance between the movable tail stock 174 and the cone punching and curling mold base 5, that is, changing the position between the movable tail stock 174 and the ejector rod 505, which is convenient for processing steel pipes of different lengths.

[0026] It also includes a steel pipe pace feeder 14 and a steel pipe discharging receiving rack 16, which are arranged on both sides of the steel pipe distributor 13. The steel pipe pace feeder 14 is used to provide the steel pipes to be processed to the steel pipe distributor 13, and the steel pipe discharging receiving rack 16 is used to receive the processed steel pipes, and the steel pipe discharging receiving rack 16 is inclined.

[0028] The steel pipe step feeder 14 also includes a feeder slide bar 146, which is fixedly connected to the frame 1, and the feeder frame 141 is slidably matched with the feeder slide bar 146.

[0029] After the steel pipe is transported to the feeder frame 141, it will roll to the lowest point of the material receiving part on the feeder frame 141. After the feeder cylinder 144 moves, it can drive the feeder push rod 146 to move. The feeder push rod 146 can extend from the through groove 147 to push the steel pipe to be processed from the previous material receiving part to the next material receiving part. In order to facilitate the rolling of the steel pipe, the top of the feeder push rod 146 is inclined, that is, the height close to the front material receiving part is high, and the height close to the rear material receiving part is low. After all the material receiving parts are filled with the steel pipes to be processed, the steel pipe distributor 13 can be started to take away the steel pipes.

The distributor servo motor 19 and the distributor reducer 20 cooperate to drive the distributor input shaft 1307 to rotate, so that the gear 1306 drives the rack 1305 to move, thereby realizing the left and right movement of the distributor frame 1301, that is, driving the steel pipe to move between the steel pipe step feeder 14, the tailstock adjustment mechanism 17 and the steel pipe discharge receiving frame 16. The distributor cylinder 1309 is used to push the distributor frame 1301 to move up and down. During the production process, the distributor frame 1301 is first driven by the distributor servo motor 19 to move to the steel pipe step feeder 14, and then drive the divider cylinder 1309 to make the divider frame 1301 rise, take away the steel pipe, and then drive the divider frame 1301 to move to the vicinity of the tailstock adjustment mechanism 17 through the divider servo motor 19, and then drive the divider cylinder 1309 to make the divider frame 1301 descend, and place the steel pipe between the first support block 173 and the second support block 177 for cone punching and rolling. After the cone punching and rolling are completed, the processed steel pipe is lifted up by the divider frame 1301 and transported to the vicinity of the steel pipe discharging and receiving frame 16, and the divider cylinder 1309 is controlled to make the divider frame 1301 descend for unloading.

The pipe pressing mechanism 15 includes a gantry 151, on which a vertically arranged pipe pressing cylinder 152 is installed. A pressing block 153 for fixing the steel pipe is installed at the output end of the pipe pressing cylinder 152. During the cone punching and curling process, the steel pipe to be processed is pressed by the pressing block 153 to avoid the movement of the steel pipe, thereby improving the stability of the steel pipe during the processing.

[0032] A control operation box 18 is installed at the upper end of the gantry 151 .

[0033] In this device, a cone punching and rolling module is provided, in which a cone punching and rolling die seat 5 is driven by a cone punching and rolling servo motor 6 to move, so as to perform cone punching treatment on the end of the steel pipe. The cone punching and rolling die seat 5 includes a die seat body 501 and a shaping die head 506. The die seat body 501 presses the end of the steel pipe to press the end of the steel pipe into a cone shape. With the continuous pressing of the die seat body 501, the end of the steel pipe is blocked by the shaping die head 506 and then rolled, so as to perform rolling shaping. The whole cone punching and rolling process is convenient and fast.

[0034] In the present device, before punching the cone and rolling the mouth, the material is fed through the steel pipe step feeder 14, and then the steel pipe is transported to between the cone punching and rolling die seat 5 and the tailstock adjustment mechanism 17 through the steel pipe distributor 13, and the steel pipe is supported by the first support block 173 and the second support block 177 for punching the cone and rolling the mouth. After the punching and rolling the mouth is completed, the die seat body 501 is retracted, and the steel pipe is transported to the steel pipe discharging and receiving rack 18 through the steel pipe distributor 13, and the processed steel pipe is output. The whole operation process has a high degree of automation, which can effectively improve the processing efficiency and has high safety performance.

[0035] In this device, multiple cone punching and rolling die seats 5 are provided, which can process multiple steel pipes at one time, can effectively save energy, improve energy utilization, and reduce energy consumption. In conjunction with the steel pipe step feeder 14 and the steel pipe distributor 13, the processing time can be further shortened, the standby time of the power equipment can be reduced, and the energy consumption can be further reduced.
