Description

Technical Field

[0001] This utility model relates to the technical field of cable processing equipment, and in particular to the technical field of a D-type cable pressing device. Background Technology

[0002] D-type cables have a semi-circular conductor, which helps save on cable costs. The semi-circular conductor core is a completely new internal cable structure compared to the round conductor core. Using a semi-circular conductor core can improve the bending performance of the cable while maintaining the same insulation sheath thickness. However, during the processing of D-type cables, the semi-circular conductor core is prone to twisting and deformation, resulting in a serpentine and loose cable core, or even damage to the surface of the cable core, thus affecting the cable quality. Summary of the Invention

[0003] The purpose of this invention is to solve the problems in the prior art by proposing a D-type cable molding device that can mold and prevent torsion deformation of the semi-circular conductor core of the D-type cable, precisely adjust the height position of the upper extrusion roller, ensure the stable position of the lower extrusion roller, has a wide range of applications, and helps to improve cable quality.

[0004] To achieve the above objectives, this utility model proposes a D-type cable pressing device, including a frame, a pressure sensor, a support base, a lower pressing roller, a pressure display, an upper pressing roller, an arc-shaped annular groove, a lifting guide plate, a lifting slider, an electric lifting hydraulic cylinder, a first distance sensor, a first hydraulic lock, and a control center. The lower part of the frame is provided with a support base, on which the lower pressing roller is mounted. The upper pressing roller is positioned directly above the lower pressing roller, and an arc-shaped annular groove is formed around the circumference of the upper pressing roller. A lifting guide plate is vertically mounted on the upper part of the frame, and a lifting slider is slidably mounted on the lifting guide plate. The upper pressing roller... The upper extrusion wheel is fixedly installed at the bottom of the lifting slider. A pressure sensor is installed at the connection between the upper extrusion wheel and the lifting slider. A pressure display is connected to the pressure sensor. An electric lifting hydraulic cylinder is installed on the top of the lifting slider. The top of the electric lifting hydraulic cylinder is fixedly installed on the top of the frame. A first distance sensor is installed at the fixed part of the electric lifting hydraulic cylinder, facing the upper extrusion wheel. A first hydraulic lock is installed on the electric lifting hydraulic cylinder. A control center is installed on the side of the frame. The control center is connected to the pressure sensor, the pressure display, the electric lifting hydraulic cylinder, the first distance sensor, and the first hydraulic lock.

[0005] Preferably, the circumferential surface of the lower extrusion roller is provided with a raised arc of 1-2°.

[0006] Preferably, the surfaces of the upper and lower extrusion rollers are uniformly coated with a wear-resistant ceramic coating.

[0007] Preferably, the pressure display is fixedly installed on the front side of the control center.

[0008] The beneficial effects of this utility model are as follows: By combining a frame, pressure sensor, support base, lower extrusion roller, pressure display, upper extrusion roller, arc-shaped annular groove, lifting guide plate, lifting slider, electric lifting hydraulic cylinder, first distance sensor, first hydraulic lock, and control center, and through experimental optimization, this utility model can mold the semi-circular conductor core of D-type cable to prevent torsional deformation through the arc-shaped annular groove of the upper extrusion roller in conjunction with the circumference of the lower extrusion roller. The upper extrusion roller can freely lift and lower to adjust the molding gap width. The lifting slider, in conjunction with the lifting guide plate, can limit the trajectory of the upper extrusion roller to prevent it from swinging under force. The electric lifting hydraulic cylinder, in conjunction with the first distance sensor, can accurately adjust the height position of the upper extrusion roller. The first hydraulic lock can lock the lifting part of the electric lifting hydraulic cylinder to ensure the stable position of the upper extrusion roller. The pressure sensor, in conjunction with the pressure display, can monitor and display the pressure value borne by the upper extrusion roller in real time. This allows the control center to conveniently monitor and adjust the pressure applied to the cable by the electric lifting hydraulic cylinder. It has a wide range of applications and helps improve cable quality.
