Description

Technical Field

[0001] This utility model belongs to the field of steel pipe processing, and specifically relates to a chamfering machine for the ends of circular steel pipes. Background Technology

[0002] Steel pipe is a tubular steel material that is widely used in many fields due to its wide range of applications.

[0003] During the processing of steel pipes, the cross-section of the steel pipe needs to be chamfered. This is mainly to meet the requirements of subsequent welding work, ensure assembly accuracy, remove surface burrs, ensure stress concentration, and achieve a more aesthetically pleasing appearance.

[0004] Chinese Patent CN210587481U discloses a steel pipe internal chamfering device, relating to the field of steel pipe processing technology. It addresses the problem that existing internal chamfering devices cannot adapt to the internal chamfering processing of steel pipes of different lengths. This invention includes a base and a worktable mounted on the base. From left to right, the worktable is provided with a support seat, a support platform, and a vertical plate. A motor is mounted on the support seat, with its output shaft horizontally positioned and a tapered chamfering cutter at its end. The support platform has clamping mechanisms for holding the front and rear sides of the steel pipe. The worktable has two sliding grooves perpendicular to the vertical plate, and the vertical plate has sliders that cooperate with the sliding grooves. A pushing mechanism on the worktable drives the vertical plate to slide along the sliding grooves. A truncated cone, corresponding to the height of the chamfering cutter, is horizontally mounted on the vertical plate, with the side of the truncated cone closer to the chamfering cutter being smaller. This invention has the advantages of simple structure and the ability to adapt to the internal chamfering processing of steel pipes of different lengths by adjusting the position of the vertical plate.

[0005] The above technical solution has the following drawbacks:

[0006] When performing chamfering operations, the waste generated cannot be cleaned and collected, affecting the workshop environment and worker safety. Utility Model Content

[0007] To address the above deficiencies, this utility model provides a circular steel pipe end chamfering machine, including a hopper, an electric gripper for clamping the pipe, and a cutting device for chamfering. The left and right sides of the hopper are respectively equipped with base plates via brackets. The top of the base plates is equipped with slide rails that are integrally formed with sliders at the four corners of the cutting device. The cutting device moves horizontally via an electric push rod installed on the same side of the hopper. The cutting device is driven by a motor installed on its top. A radiator is installed at the heat dissipation port of the motor, and an inclined air outlet pipe is installed at the end of the radiator near the hopper.

[0008] The top of the hopper is provided with a telescopic channel for the electric gripper to pass through. The left and right sides of the hopper are provided with slots for the air duct and the output end of the cutting equipment to pass through. The hopper is also equipped with a limiting component for clamping steel pipes. The bottom of the back of the hopper is provided with several slag discharge troughs and is connected to the waste slag bucket through an external recycling pipe.

[0009] Furthermore, a transparent baffle made of PET material is installed at the top of the hopper, and the transparent baffle is located at the front of the telescopic channel.

[0010] Furthermore, the opening on the front of the hopper is hinged to a sealing door for sealing, and the inner bottom wall of the hopper is a slope that is higher in the front and lower in the back.

[0011] Furthermore, the slag discharge troughs are arranged in a matrix, and each slag discharge trough is conical, with the end with the larger diameter located on the inner wall of the silo and the end with the smaller diameter located on the outer wall of the silo.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] Simultaneous chamfering of both ends of the steel pipe can be performed, greatly improving the efficiency of chamfering. At the same time, the air force emitted by the motor and the airflow guided by the radiator not only dissipate heat from the motor, but also blow the exhaust air to the waste generated inside the hopper, causing it to be discharged into the recycling pipe through the ramp, thus completing the collection and treatment of waste residue.

Embodiments of the device are shown in the drawings. However, this device can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting.

[0019] Example

[0020] like Figure 1-2 As shown, this embodiment provides a circular steel pipe end chamfering machine, including a hopper 1, an electric gripper 4 for clamping the pipe, and a cutting device 6 for chamfering. It should be noted that the electric gripper 4 is a commonly used actuator in automated equipment, mainly used for gripping, moving, and placing objects. Compared with traditional pneumatic grippers, the electric gripper 4 uses an electric motor to drive the clamping or releasing action. The cutting device 6 for chamfering includes a housing, a drive shaft, and a cutting head or tool for performing the chamfering process. The drive shaft is driven to rotate by the motor, causing the cutting head or tool installed on the drive shaft to rotate and chamfer the steel pipe.

[0021] The left and right sides of the hopper 1 are respectively equipped with base plates by brackets. The opening on the front of the hopper 1 is hinged with a sealing door 10 for sealing, which facilitates the subsequent retrieval of the chamfered steel pipe. The top of the base plate is equipped with slide rails 5 that are integrally formed with the sliders at the four corners of the cutting equipment 6. The cutting equipment 6 moves horizontally by electric push rods 9 installed on the same side of the hopper 1 (the two electric push rods 9 move synchronously in the same direction, which can be achieved by a PLC controller, which will not be described in detail here). The cutting equipment 6 is driven by a motor 7 installed on its top. The heat dissipation port of the motor 7 is equipped with a heat sink 8. An inclined air outlet duct 11 is installed at the end of the heat sink 8 near the hopper 1. The heat sink 8 can dissipate heat from the motor 7 and also increase the airflow emitted by the motor 7 before delivering it to the inside of the hopper 1 to blow away the waste chips.

[0022] The top of the hopper 1 has a telescopic channel 14 for the electric gripper 4 to pass through. The left and right sides of the hopper 1 have slots 13 for the air supply duct 11 and the output end of the cutting equipment 6 to pass through. Inside the hopper 1, a limiting component 18 for clamping steel pipes is also installed. The limiting component 18 is used to clamp the steel pipes conveyed by the electric gripper 4, ensuring the stability of the steel pipes during subsequent chamfering operations. In this embodiment, this is achieved through an electric push rod and a steel pipe seat. The electric push rod and the steel pipe seat are located on the inner wall of the hopper 1 and the inner wall of the sealing door 10, respectively, and are on the same horizontal line. The output end of the electric push rod is fixed with a pressing head adapted to the steel pipe seat (both are arc surfaces adapted to the outer surface of the steel pipe). Figure 2 As shown;

[0023] Several slag discharge troughs 16 are provided at the bottom of the back side of the silo 1 and are connected to the waste residue bin through an externally connected recycling pipe 17. The slag discharge troughs 16 are distributed in a matrix and each slag discharge trough 16 is conical. The end with the larger diameter is located on the inner wall of the silo 1 and the end with the smaller diameter is located on the outer wall of the silo 1. The inner bottom wall of the silo 1 is a slope 15 with a higher front and a lower back. Its function is that when the wind is delivered into the silo 1, it can blow the accumulated waste inside and guide it to the slag discharge trough 16 through the action of the slope 15, discharge it into the recycling pipe 17, and then transport it into the waste residue bin through the recycling pipe 17 to complete the collection and treatment of waste residue.

[0024] Meanwhile, a transparent baffle 12 made of PET material is installed at the top of the hopper 1, and the transparent baffle 12 is located at the front of the telescopic channel 14, which makes it convenient for staff to observe the clamping situation, and will not cause damage to the staff observing from the front due to the flying debris.

[0025] It should be noted that the structure described in this utility model can be implemented in many different forms and is not limited to the embodiments described. Any equivalent transformations made by those skilled in the art based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, such as the loading and unloading of other items, are included within the protection scope of this utility model.
