Description

Technical Field

[0001] The utility model relates to the technical field of drill tool processing, in particular to a steel pipe feeding machine for drill tool processing. Background Art

[0002] A drill tool is a working tool for rock drilling holes. During the processing of drill tools, it is necessary to press the drill bit into a steel pipe. The Chinese utility model patent with the publication number CN210788777U in the prior art proposes a steel pipe feeding machine for drill tool production. Before feeding, the fastening bolts for fastening the drill tool mold are first loosened, the drill tool mold is moved so that the feeding port of the drill tool mold is aligned with the discharging port of the loading device, and the pressing end, the discharging port and the aforementioned feeding port of the steel pipe feeding machine are on the same vertical line. After adjustment, the fastening bolts are tightened to position the drill tool mold. Then, the drill tool steel material for processing is vertically placed on the loading device, and the drill tool steel material is clamped by the limiting baffle plates on both sides of the loading device so that it will not tilt left and right. The conveyor belt on the feeding device installed on the top of the limiting baffle plates also always contacts the side surface of the drill tool steel material, and the conveyor belts on the two limiting baffle plates also clamp the upper side of the drill tool steel material. The rotating motor is turned on, and the conveyor belt starts to move. The surface of the loading device in contact with the drill tool steel material is made of a material with a low coefficient of friction. In this way, under the action of the conveyor belt, the drill tool steel material can move vertically between the limiting baffle plates. When the drill tool steel material moves to the position of the discharging port, the drill tool steel material falls under the action of its own gravity and is discharged from the feeding device. The operator only needs to vertically place the drill tool steel material between the limiting baffle plates and control the opening and closing of the rotating motor to realize the continuous feeding of the drill tool material. The steel material moving on the loading device can directly fall from the discharging port into the feeding port of the drill tool mold. During the pressing process, the worker turns off the rotating motor. After pressing is completed, the rotating motor is turned on again to continue feeding. In this way, the manual feeding process of the worker is greatly saved, the feeding efficiency is improved, and the working efficiency of the steel pipe feeding machine is increased.

[0003] However, in the above prior art, the pressing end descends to press the steel pipe into the drill tool mold to be combined with the drill bit. After the feeding is completed, the above prior art cannot take out the steel pipe together with the drill bit from the drill tool mold and perform automatic blanking. Manual blanking has a large labor intensity and low working efficiency. Summary of the Utility Model

The piston rod of the pressure cylinder is extended to push the pressing block and the pressing head downward, thereby pressing the steel pipe into the drill tool mold, so that the drill bit pre-installed in the drill tool mold is pressed onto the end of the steel pipe. After the pressing is completed, the piston rod of the pressure cylinder is contracted to take the steel pipe and the drill bit out of the drill tool mold, the pressing head is turned 270 degrees clockwise, and the steel pipe is put back on the feeding mechanism. The electromagnet is powered off to release the steel pipe, and the feeding mechanism sends the steel pipe into the unloading area for unloading.

[0024] Embodiment 2

[0025] As Figures 4 to 7As shown, on the basis of Embodiment 1, the feeding mechanism includes a first roller rack 10, a plurality of long rollers 11, a pushing cylinder 12, a second roller rack 13, a plurality of short rollers 14, a reduction motor 16 and a transmission assembly 17. The plurality of long rollers 11 are rotatably installed on the upper part of the first roller rack 10. The plurality of long rollers 11 are inclined, with the front ends of the plurality of long rollers 11 inclined downward. The middle parts of the plurality of long rollers 11 are aligned with the pressing head 5. The reduction motor 16 is installed on the first roller rack 10, and the reduction motor 16 drives the plurality of long rollers 11 to rotate synchronously through the transmission assembly 17. The pushing cylinder 12 is vertically arranged, and the second roller rack 13 is installed at the top end of the piston rod of the pushing cylinder 12. The plurality of short rollers 14 are rotatably installed on the second roller rack 13. The plurality of short rollers 14 are inclined, with the rear ends of the plurality of short rollers 14 inclined downward. The plurality of short rollers 14 and the plurality of long rollers 11 are arranged in an alternating manner, and the rear ends of the plurality of short rollers 14 are aligned with the pressing head 5; it further includes a vibration sensor 15, and the vibration sensor 15 is installed on the second roller rack 13 to detect the vibration of the second roller rack 13; it further includes a mounting bracket 18 and a photoelectric switch 19. The mounting bracket 18 is installed on the first roller rack 10, and the photoelectric switch 19 is installed on the mounting bracket 18.

[0026] The plurality of long rollers 11 and the plurality of short rollers 14 are arranged in a V-shaped alternating manner, so that the plurality of long rollers 11 and the plurality of short rollers 14 roll to support the steel pipe. Adjust the position of the photoelectric switch 19 on the mounting bracket 18 according to the length of the steel pipe and the position of the external receiving box. The reduction motor 16 drives the plurality of long rollers 11 to rotate synchronously through the transmission assembly 17, so that the plurality of long rollers 11 friction the steel pipe to convey the steel pipe, and the steel pipe can be sleeved on the plug 6. After the steel pipe with pressing completed is placed on the plurality of long rollers 11 and the plurality of short rollers 14 again, the steel pipe impacts the plurality of short rollers 14 to cause vibration of the second roller rack 13. After the vibration sensor 15 detects the vibration, an electric signal is generated. The controller of the reduction motor 16 receives the above electric signal and starts to operate, so that the plurality of long rollers 11 rotate to take out the steel pipe from the plug 6. When the steel pipe with pressing completed blocks the photoelectric switch 19, the photoelectric switch 19 emits a signal to stop the reduction motor 16. At this time, the steel pipe is aligned with the external receiving box, and the pushing cylinder 12 starts to contract.

Multiple long rollers 11 and multiple short rollers 14 continue to convey the steel pipe, so that the steel pipe is sleeved on the plug 6 and abuts against the pressing head 5. The electromagnet 7 is energized to generate magnetic force to adsorb the steel pipe. Then, the driving component drives the pressing head 5 to rotate so that the plug 6 rotates the steel pipe counterclockwise by 270 degrees, making the steel pipe vertically located above the drill tool mold 1. The piston rod of the pressing cylinder 3 extends to push the pressing block 4 and the pressing head 5 downward, thereby pressing the steel pipe into the drill tool mold 1, so that the drill bit pre-installed in the drill tool mold 1 is pressed onto the end of the steel pipe to complete the pressing. Then, the piston rod of the pressing cylinder 3 contracts to take out the steel pipe together with the drill bit from the drill tool mold 1. The pressing head 5 rotates clockwise by 270 degrees to place the steel pipe back onto multiple long rollers 11 and multiple short rollers 14. The electromagnet 7 is de-energized to release the steel pipe. Finally, multiple long rollers 11 rotate to take out the steel pipe from the plug 6. When the steel pipe is aligned with the external material receiving box, the reduction motor 16 stops, and the pushing cylinder 12 starts to contract, so that the roller frame two 13 drives multiple short rollers 14 to descend, so that multiple short rollers 14 descend below multiple long rollers 11, and the steel pipe slides along the inclined multiple long rollers 11 into the external material receiving box.
