Description

Automatic rotatory tire section cutting device

Technical Field

The invention relates to the technical field of tire cutting, in particular to an automatic rotating tire section cutting device.

Background

Radial tires gradually replace traditional bias tires due to their superiority in structural performance and the like, and become mainstream products in the tire industry. However, because of the structural characteristics and the particularity of the use conditions of the radial tire, special tests such as durability, balance uniformity, infrared rays, ultrasonic waves and the like are required to be carried out, and the tire section cutting test is to sample and detect the tire after the tire path test. The uniformity of the tire section, the interval uniformity of the cord threads with or without holes and the like can be visually determined through section analysis, and meanwhile, the adhesive condition of glue at each part and the staggering property of a steel wire pipe and a belted layer steel wire can be checked. The tire section cutting test is an important means for detecting whether the internal structure of the radial tire is reasonable or not, and is an important guarantee for the use safety of the tire.

Through searching relevant patent publication documents of tire section cutting devices in the tire detection process, Chinese patent CN204183608U is found, and the cutting machine comprises a vertical lifting device and a transverse feeding mechanism arranged on the vertical lifting device, wherein the transverse feeding mechanism comprises a vertical cutting cutter disc, a cutting cutter disc transmission mechanism and a cutting cutter disc feeding mechanism and is used for cutting tires. Compared with manual cutting, the technical scheme of the patent has great progress, but along with the higher and higher requirements on the detection of the tire in the automobile industry, the demand is higher and higher, the automation degree of the cutting is relatively low, and the cutting of the whole section is completed by the rotation of the tire through human intervention. In view of the above, how to improve the automation degree of the section cutting device becomes a key point for further improving the tire section cutting device.

Disclosure of Invention

The invention mainly solves the technical problems that: the utility model provides an autogiration tire section cutting device can realize tire autogiration and the sectional automatic cutout of tire, improves the efficiency and the automation level that tire production detected, satisfies high requirement, the high standard that detects the tire.

The technical scheme adopted by the invention for solving the technical problems is as follows: an automatic rotating tire section cutting device comprises a limit switch, a hydraulic loader, a knife rest, a cutting knife, a contact switch, a supporting upright post, a clamping arm, a workbench, a rolling shaft and a motor. The limit switch is installed on the platform of hydraulic pressure loader rear side, and the cutting knife is connected with the hydraulic pressure loader through the knife rest, and the support post is located the intermediate position of workstation and is equipped with the roller bearing around and, and contact switch installs in the recess of support post, presss from both sides tightly to embrace the arm bottom and is connected the both sides of distributing at the workstation with the motor. In actual work, a tire to be cut is sleeved on the supporting upright post, the clamping arm clamps the tire, and the hydraulic loader pushes the cutting knife to feed in the radial direction to cut the tire; when the cutting knife touches the contact switch in the groove of the support upright post, the hydraulic loader drives the cutting knife to return, and the first tire cutting is completed. When the hydraulic loader retreats to limit switch, the hydraulic loader stops retreating, and the tire is rotated under the tight arm of holding of clamp and the front and back roller bearing combined action, and when the tire rotated to suitable position, the hydraulic loader promoted the cutting knife and cut the tire once more, accomplished the cutting to the whole section of tire so far.

The automatic rotating tire section cutting device provided by the invention can realize automatic rotation of the tire and automatic cutting of the tire section, improves the efficiency and the automation level of tire production detection, and meets high requirements and high standards for tire detection.

Detailed Description

In order that those skilled in the art will be better able to understand the present invention, the following detailed description of the invention is given in conjunction with the accompanying drawings.

An automatic rotating tire section cutting device is composed of a limit switch (1), a hydraulic loader (2), a tool rest (3), a cutting knife (4), a contact switch (5), a supporting upright post (6), a clamping arm (7), a workbench (8), a rolling shaft (9) and a motor (10). The limiting switch (1) is installed on a platform on the rear side of the hydraulic loader (2), the cutting knife (4) is connected with the hydraulic loader (2) through the knife rest (3), the supporting upright post (6) is located in the middle of the workbench (8), the front and the rear of the supporting upright post are provided with the rolling shafts (9), the contact switch (5) is installed in a groove of the supporting upright post (6), and the bottom of the clamping arm (7) is connected with the motor (10) and distributed on two sides of the workbench (8). In actual work, a tire to be cut is sleeved on the supporting upright post (6), the tire is clamped by the clamping arm (7), and the hydraulic loader (2) pushes the cutting knife (4) to feed radially to cut the tire; when the cutting knife (4) touches the contact switch (5) in the groove of the support upright post (6), the hydraulic loader (2) drives the cutting knife (4) to return, and the first tire cutting is completed. When the hydraulic loader (2) retracts to the limit switch (1), the hydraulic loader (2) stops retracting, the tire rotates under the combined action of the clamping arm (7) and the front and rear rolling shafts (9), and when the tire rotates to a proper position, the hydraulic loader (2) pushes the cutting knife (4) to cut the tire again, so that the cutting of the whole section of the tire is completed.

The supporting upright post (6) and the cutting knife (4) are oppositely provided with grooves for ensuring the cutting knife (4) to completely cut the tire along the radial direction.

The rolling shaft (9) is slightly higher than the working table (8) and is used for heightening and sleeving the tire on the supporting upright post (7), so that the cutting knife (4) can be used for cutting the tire completely along the axial direction.
