Description

Technical Field

[0001] This utility model relates to the field of steel pipe processing technology, and in particular to a piercing machine for high-temperature steel pipe processing. Background Technology

[0002] High-temperature steel pipes refer to steel pipes that can withstand high temperature, high pressure and corrosive media under high temperature conditions (usually above 400℃).

[0003] Currently, in the process of piercing high-temperature steel pipes, the pipe is usually installed on a fixture and the drilling is done manually with a hand-held electric drill. However, in actual application, the drill bit may slip or deviate when it comes into contact with the pipe wall, and the drilling accuracy cannot be guaranteed. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a piercing machine for high-temperature steel pipe processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A piercing machine for processing high-temperature steel pipes includes a worktable, a clamping mechanism is installed on the upper part of the worktable, a connecting arm is arranged directly above the clamping mechanism, the connecting arm is vertically moved by a lifting platform, an electric drilling machine is installed at one end of the connecting arm, and clamping components are arranged on both sides away from the electric drilling machine.

[0007] The clamping assembly includes a support base and an arc-shaped pressure plate. The support base is fixedly installed on the outside of the connecting arm. A pair of limiting grooves are opened in the middle of the support base. A connecting rod is installed in the limiting groove. The bottom of each connecting rod is connected to the arc-shaped pressure plate. A spring is connected between each connecting rod and the limiting groove.

[0008] In addition, a preferred structure is that a lifting platform is installed on one side of the upper part of the worktable, a pair of limiting rods are installed in the middle of the lifting platform, a connecting arm is installed on the upper limit of the limiting rods, and a spring is sleeved on the outer side of the limiting rods, and the spring is connected to the bottom wall of the lifting platform.

[0009] Furthermore, a preferred configuration is that the spring deforms when the lifting platform moves vertically.

[0010] In addition, a preferred structure is that a handle is installed on the upper side of the connecting arm, and an electric drilling machine control switch is provided at the bottom of the handle, and the electric drilling machine control switch is electrically connected to the electric drilling machine.

[0011] Furthermore, a preferred configuration is that, in its natural state, the bottom end of the arc-shaped pressure plate extends beyond the bottom end of the electric drilling machine.

[0012] In addition, a preferred structure is that the bottom wall of the arc-shaped pressure plate is provided with a rubber pad.

[0013] The beneficial effects of this utility model are as follows:

[0014] In this invention, during the downward drilling process of the electric drilling machine, the arc-shaped pressure plate will first contact the upper wall of the pipe and, through the setting of the second spring, firmly press the upper wall of the pipe, which plays the role of pressing and limiting and supporting the left and right sides of the connecting arm. At this time, the drilling operation will effectively avoid the situation of displacement and slippage during drilling, thus ensuring processing efficiency. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-4 A high-temperature steel pipe processing piercing machine includes a worktable 1, a clamping mechanism 2 is installed on the upper part of the worktable 1, a connecting arm 4 is arranged directly above the clamping mechanism 2, the connecting arm 4 is vertically moved by a lifting platform 3, an electric drilling machine 6 is installed at one end of the connecting arm 4, and clamping components are arranged on both sides away from the electric drilling machine 6.

[0022] Furthermore, the clamping assembly includes a support base 9 and an arc-shaped pressure plate 10. The support base 9 is fixedly installed on the outside of the connecting arm 4. A pair of limiting grooves 14 are opened in the middle of the support base 9. A connecting rod 12 is installed in the limiting groove 14. The bottom of each connecting rod 12 is connected to the arc-shaped pressure plate 10. A spring 13 is connected between each connecting rod 12 and the limiting groove 14.

[0023] A lifting platform 3 is installed on the upper side of the workbench 1. A pair of limit rods 8 are installed in the middle of the lifting platform 3. A connecting arm 4 is installed on the upper limit of the limit rods 8. A spring 7 is sleeved on the outer side of the limit rods 8 and connected to the bottom wall of the lifting platform 3.

[0024] When the lifting platform 3 moves vertically, spring 7 deforms.

[0025] When the lifting platform 3 moves down, the spring 7 is compressed to generate a rebound force.

[0026] A handle 5 is installed on the upper side of the connecting arm 4, and an electric drilling machine control switch 51 is provided at the bottom of the handle 5. The electric drilling machine control switch 51 is electrically connected to the electric drilling machine 6.

[0027] In its natural state, the bottom end of the arc-shaped pressure plate 10 extends beyond the bottom end of the electric drilling machine 6, so that during the drilling process, the arc-shaped pressure plate 10 contacts the pipe fitting first to press it down.

[0028] A rubber pad 11 is provided on the bottom wall of the arc-shaped pressure plate 10 to increase the contact friction.

[0029] In this embodiment, the clamping mechanism 2 locks the high-temperature steel pipe to be processed. The operator holds the handle 5 and drives the connecting arm 4 downward. During the downward movement of the connecting arm 4, the arc-shaped pressure plate 10 contacts the upper wall of the pipe. The rubber pad 11 increases the friction to ensure the stability during clamping. Under the relative force, the arc-shaped pressure plate 10 remains stationary. The connecting arm 4 drives the electric drilling machine 6 to continue to move downward. At this time, the electric drilling machine control switch 51 is activated to control the electric drilling machine 6 to rotate and drill, and contact the surface of the pipe for piercing.

[0030] The connecting arm 4 slides on the limiting rod 8. During the downward movement, the connecting arm 4 compresses the spring 7, causing the spring 7 to generate a rebound force, so as to drive the connecting arm 4 to rise and reset after the drilling is completed.

[0031] The operation and shutdown of the electric drilling machine 6 are controlled by the electric drilling machine control switch 51. This is a conventional configuration in this technical field, and the specific circuit connection and operating principle will not be explained further.

[0032] The arc-shaped pressure plate 10 presses against the pipe wall and serves to press and limit the pipe fitting, while also preventing the connecting arm 4 from shaking or shifting. After the arc-shaped pressure plate 10 presses against the pipe fitting, the drill bit of the electric drilling machine 6 contacts the pipe fitting to open the hole. At this time, the arc-shaped pressure plates 10 set on both sides of the connecting arm 4 can provide lateral support, not only pressing and limiting the pipe fitting, but also providing effective friction to effectively prevent the drill bit from shifting.

[0033] When the connecting rod 12 is fully inserted into the limiting groove 14, that is, at the end of the stroke of the connecting rod 12, the bottom of the arc-shaped pressure plate 10 is higher than the bottom of the drill bit of the electric drilling machine 6.

[0034] The clamping mechanism 2 is a standard configuration in this technical field and can be directly purchased and used from the market, so it will not be explained further.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
