Description
Technical Field
[0001] The utility model relates to the technical field of cutting machines, in particular to an automatic cutting device for high-pressure oil pipes. Background Art
[0002] The existing cutting machine is a device composed of a rotating mechanism and a connecting rod reciprocating mechanism. After the product is placed on the cutting platform, the product is pressed onto the cutting blade of the rotating mechanism using the force of the connecting rod reciprocating mechanism. The length of the oil pipe and the cutting operation are performed manually, which increases the fatigue of the employees and has a high risk factor.
[0003] The product is placed flat on the platform without fixing its front and rear freedom for cutting, which is prone to bevel cutting. In the cutting process, people are needed to assist in delivering the oil pipe, and the operator needs to concentrate and wear goggles for cutting. The cutting quality and cutting length will be affected by the operator, so the appearance and quality of the product cannot be guaranteed to be uniform. Utility Model Content
[0004] In order to solve the above problems existing in the prior art, the utility model provides a high-pressure oil pipe automatic cutting device, which is realized by the following technical solutions:
[0005] An automatic cutting device for high-pressure oil pipes includes a cutting machine motor and a cutting blade for cutting, and a feed wheel motor, a first feed wheel, and a second feed wheel for conveying the oil pipe to be cut. The cutting machine motor is fixed on a motor base, and the motor base is fixed in a cavity. One end of the cutting machine motor is rotatably connected to the cutting blade. The top surface of the cavity is provided with an opening, and the side wall is provided with heat dissipation holes. A cylinder is provided above the opening, and a pressing assembly is provided at the lower end of the cylinder. The cutting blade, the opening, and the cylinder are in the same vertical line, so that the cylinder and the pressing assembly can pass through the opening. The first feed wheel is connected to the feed wheel motor, and the feed wheel motor is mounted on the motor base. The second feed wheel is mounted on the feed wheel support rod, and is in the same vertical line as the center of the first feed wheel.
[0006] Furthermore, the oil pipe to be cut is clamped between the first feeding wheel and the second feeding wheel. As the feeding wheel motor drives the first feeding wheel to rotate, the first feeding wheel and the second feeding wheel cooperate to transport the oil pipe to be cut. The second feeding wheel is provided with a first guide plate and a second guide plate on both sides, and the feeding wheel support rod is fixed between the first guide plate and the second guide plate. A protective cover is provided above the first feeding wheel, and the protective cover is supported on the first guide plate and the second guide plate to protect the first feeding wheel and the second feeding wheel therein.
[0007] Furthermore, a guide head and a guide tube are provided at one end of the second guide plate away from the first guide plate, the first guide plate and the second guide plate have openings, and the oil pipe to be cut passes through the opening of the first guide plate, the opening of the second guide plate, the guide head and the guide tube in sequence, thereby limiting the degree of freedom of the oil pipe to be cut.
[0008] Furthermore, an encoder is installed on the cavity between the guide head and the cylinder, a cylinder cover is arranged outside the cylinder, and a screen is placed above the cylinder cover. Before cutting, the cutting length is set on the screen, and the encoder will measure the length of the oil pipe to be cut.
[0009] Furthermore, a first guide plate and a second guide plate are installed on the cavity on the right side of the cylinder, and the first guide plate and the second guide plate are distributed on both sides of the central axis of the oil pipe to be cut, so as to further limit the oil pipe to be cut.
[0010] Furthermore, the opening of the cavity is rotatably connected to a baffle. When the length of the oil pipe to be cut through the encoder reaches the cutting length set on the screen, the cylinder drives the pressing assembly to press the oil pipe to be cut down onto the cutting blade, and the baffle is opened. After the cutting is completed, the cylinder returns to the initial position, and the baffle also rebounds to the initial position.
[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0012] (1) The first feeding wheel, the second feeding wheel and the cylinder are provided with protective covers to avoid the safety hazards to the operator caused by gear meshing and cylinder movement, and also increase the aesthetics of the device;
[0013] (2) The cutting blade is installed in the cavity and the cavity is closed by a baffle, which further ensures the safety of the operator;
[0014] (3) The length of the oil pipe to be cut is measured by an encoder, making the cutting process more automated and more accurate;
[0015] (4) The oil pipe to be cut is limited and controlled by the first guide plate, the second guide plate, the guide head, the first guide plate and the second guide plate, thereby avoiding irregularities such as bevel cutting. BRIEF DESCRIPTION OF THE DRAWINGS
