Description

Technical Field

[0001] This utility model relates to the technical field of structural steel, and in particular to the technical field of drilling irregularly shaped steel. Background Technology

[0002] Section steel is a type of strip steel with a specific cross-sectional shape and size, and is one of the four major types of steel. Based on cross-sectional shape, section steel is divided into simple section steel and complex section steel. The former refers to square steel, round steel, flat steel, angle steel, hexagonal steel, etc.; the latter refers to I-beams, channel steel, rails, window frame steel, bent section steel, etc., and is sometimes also called special-shaped steel. Section steel is a structural design undertaken to minimize weight and cost while ensuring strength to the greatest extent possible. Generally, its main structure consists of steel plates of a certain thickness bent and spliced ​​in different ways. Section steel is mainly used in the processing of building or industrial equipment. On the construction site, holes need to be drilled at certain locations on the section steel to meet the requirements for connection with other structures. To improve the accuracy of the construction and avoid safety issues, the drilling positions need to be as accurate as possible, especially in some cases where multiple equally spaced holes need to be drilled.

[0003] Existing patent CN217070836U discloses a drilling device for processing steel profiles, which can perform drilling operations on steel profiles, but it is only suitable for steel profiles that can be placed stably, and not suitable for irregular steel profiles that are difficult to place stably.

Detailed Implementation

[0016] Example 1:

[0017] See Figure 1 and Figure 2 This utility model relates to a drilling device for irregularly shaped steel, comprising a machine base 1, a mold 2, a drilling channel 21, a chip removal channel 22, a chip removal pipe 23, a chip collection box 24, a mounting frame 15, drilling components, and a traction device 11. A mold 2 is fixed on the machine base 1. The mold 2 has a horizontally arranged die hole 20, which is adapted to the irregularly shaped steel 3 through which the steel 3 passes. The mold 2 has several straight drilling channels 21, with the inlet of each channel higher than its end. The die hole 20 cuts off the drilling channel 21. Each drilling channel 21 is connected to a chip removal channel 22 at its end. The chip removal channel 22 slopes downward from the end of the drilling channel 21 and opens on the outer wall of the die 2. Several chip removal tubes 23 corresponding to the drilling channel 21 are fixed on the outside of the die 2. The inlet end of the chip removal tube 23 surrounds the outlet of the corresponding drilling channel 21. The end of the chip removal tube 23 is connected to the chip collection box 24 and the chip removal tube 23 is connected to the inside of the chip collection box 24.

[0018] A mounting frame 15 is installed on the machine base 1. Several drilling assemblies corresponding one-to-one with the drilling channels 21 are installed on the mounting frame 15. The drilling assembly consists of a push-pull device 16 and a drilling machine 17. The push-pull device 16 is fixed on the mounting frame 15 and is a cylinder. The push-pull device 16 is connected to the drilling machine 17. The drilling machine 17 includes a drill bit 18. The drill bit 18 is aligned with the corresponding drilling channel 21. When the push-pull device 16 moves the drilling machine 17, the drill bit 18 moves along the central axis of the drilling channel 21.

[0019] A traction device 11 is installed on the machine base 1. The traction device 11 is located on the discharge side of the mold 2. One end of the special-shaped steel 3 is fixed to the traction device 11. The traction device 11 drives the special-shaped steel 3 to move horizontally along the length direction of the special-shaped steel 3.

[0020] To prevent the shaped steel 3 from bending, several horizontally arranged rollers 10 are installed on the machine base 1. The rollers 10 are located on the feeding side of the mold 2, and the shaped steel 3 is placed on the rollers 10.

[0021] Example 2:

[0022] To ensure effective chip removal, the chip removal channel 22 is a straight channel, and the drilling channel 21 has an angle greater than 45° with the horizontal plane.

[0023] Example 3:

[0024] To further improve the chip removal effect, the chip collection box 24 is located below the machine base 1, the end of the chip removal pipe 23 is fixed to the top wall of the chip collection box 24, and an air extractor 25 is installed on the top wall of the chip collection box 24. The air inlet of the air extractor 25 is connected to the inside of the chip collection box 24.

[0025] The working process of this utility model:

[0026] In the operation of this utility model's special-shaped steel drilling device, the special-shaped steel 3 passes through the mold hole 20 of the mold 2, and the traction device 11 drives the special-shaped steel 3 to move. When the traction device 11 drives the special-shaped steel 3 to the position where a hole needs to be drilled, the traction device 11 stops moving, and the push-pull device 16 drives the drilling machine 17 to move. The drill bit 18 on the drilling machine 17 passes through the drilling channel 21 and drills a hole in the workpiece. Then the push-pull device 16 drives the drilling machine 17 to reset, and then the traction device 11 continues to drive the special-shaped steel 3 to move until the special-shaped steel 3 moves to the next drilling position.

[0027] The debris generated during drilling will eventually fall into the chip collection box 24 through the chip drop channel 22 and chip drop pipe 23. The air pump 25 can put the chip collection box 24 under negative pressure, which will generate a suction force on the debris generated during drilling and accelerate the debris to fall into the chip collection box 24.

[0028] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
