Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe heading machines, in particular to a steel pipe heading machine. Background Art

[0002] As we all know, steel pipes have hollow sections, and their length is much longer than the diameter or circumference of steel. According to the cross-sectional shape, they are divided into round, square, rectangular and special-shaped steel pipes; according to the material, they are divided into carbon structural steel pipes, low alloy structural steel pipes, alloy steel pipes and composite steel pipes, etc. Steel pipes require a steel pipe heading machine during production.

[0003] In real life, the heading devices of most steel pipe heading machines are generally set up as an integral whole. When the hammering end face of the heading device is excessively worn and needs maintenance, the heading device needs to be disassembled as a whole for maintenance, and the hammering part cannot be replaced separately. Therefore, during the maintenance period, the steel pipe cannot be hammered, and the practicality is not very good. Secondly, when hammering hot steel pipes, some impurities of the steel pipes will adhere to the surface of the heading device during the hammering period, and the device does not have a device for cleaning these impurities. As time goes by, these impurities will form a solidified layer on the surface of the heading device, thereby increasing the difficulty of later cleaning. Therefore, the practicality is not very good and there is room for improvement. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the utility model provides a steel pipe heading machine, which has the characteristic of improving practicability.

[0006] (II) Technical solution

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a steel pipe heading machine, comprising a machine body, a plurality of heading devices are arranged at the front of the machine body, a plurality of slots are arranged in the middle of the plurality of heading devices, and a plug-in plate is inserted in each of them, a heading plate is arranged on one side of each of the plug-in plates, a plurality of first threaded holes are arranged on each of the heading plates, a plurality of second threaded holes are arranged on each of the heading devices, and they are threadedly connected with the first threaded holes through bolts, a groove is arranged in the middle of the machine body, an electric telescopic rod is installed at the rear of the groove, a motor is installed at the front of the electric telescopic rod, and a cleaning brush is arranged at the front of the motor.

[0008] Furthermore, one side end surface of several of the heading plates is in contact with one side end surface of the corresponding heading device, and one end surface of several of the heading plates is in contact with each other.

[0009] Furthermore, the cleaning brush and the groove match with a plurality of head plates, and a gap is provided between the outer end surface of the motor and the inner wall of the groove.

[0010] Preferably, the electric telescopic rod and the motor are both electrically connected to an external power source.

[0011] Preferably, the exteriors of the several bolts are coated with an anti-corrosion coating.

[0012] (III) Beneficial effects

[0013] Compared with the prior art, the utility model provides a steel pipe heading machine, which has the following beneficial effects:

[0014] When the steel pipe heading machine hammers the steel pipe for a period of time and the surface loss of the heading plate reaches the degree that requires maintenance, it is only necessary to unscrew the bolts on the heading plate, remove the heading plate, and then install a new heading plate on the heading device and fix it with bolts before working, thereby not affecting the normal hammering work. Secondly, after the hammering is completed, the cleaning brush can be driven by the electric telescopic rod to move to the heading plate, and then the cleaning brush can be driven by the motor to rotate to clean the impurities on the surface of the heading plate, thereby avoiding the impurities from forming solids on the surface of the heading plate, reducing the difficulty of later cleaning, and thus improving the practicality to a certain extent.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-6 The utility model is a steel pipe heading machine, comprising a machine body 1, a plurality of heading devices 2 are arranged at the front of the machine body 1, a plurality of slots 3 are arranged in the middle of the plurality of heading devices 2, and a plug board 4 is inserted in each of them, a heading plate 5 is arranged on one side of the plurality of plug boards 4, the plug board 4 is inserted into the slot 3 by plugging, the heading plate 5 is installed in the heading device 2, a plurality of first threaded holes 6 are arranged on the plurality of heading plates 5, a plurality of second threaded holes 7 are arranged on the plurality of heading devices 2, and the plurality of second threaded holes 7 are threadedly connected with the first threaded holes 6 by bolts 8, and the bolts 8 are screwed into the first threaded holes 6. The first threaded hole 6 and the second threaded hole 7 are used to fix the head plate 5 on the head device 2. The outer surfaces of the several bolts 8 are coated with an anti-corrosion coating to improve the anti-corrosion effect of the bolts 8. The end faces of one side of the several head plates 5 are in contact with the end faces of one side of the corresponding head device 2 to improve the stability between the head plate 5 and the head device 2. The end faces of one end of the several head plates 5 are in contact with each other. When the head device 2 drives the head plates 5 to hammer the steel pipe, the end faces of the several head plates 5 are just in contact with each other and no longer move. Then, they move away from each other in the reverse direction and leave the steel pipe, and then they are hammered several times in a cycle. The steel pipe is hammered, and a groove 9 is arranged in the middle of the machine body 1. An electric telescopic rod 10 is installed at the rear of the groove 9. A motor 11 is installed at the front of the electric telescopic rod 10. A cleaning brush 12 is arranged at the front of the motor 11. When the steel pipe is hammered and removed, the electric telescopic rod 10 is started, the electric telescopic rod 10 is extended, and the motor 11 and the cleaning brush 12 are driven to move in the groove 9. When the cleaning brush 12 moves to several head plates 5, the electric telescopic rod 10 is closed, and the motor 11 is started. The motor 11 rotates, driving the cleaning brush 12 to rotate, and several head plates 5 are cleaned, and then Turn off the motor 11 and start the electric telescopic rod 10.
