Problems solved by technology

However, ruler measurement and manual cutting machine cutting are commonly used in the production of Overlay specimens, which not only cannot guarantee the accuracy of the geometric dimensions of the specimens, but also easily wastes materials due to redundant operations, consuming a lot of time and labor costs.
The Overlay Test test has high precision requirements for the geometric dimensions of the specimen, and the precision will also profoundly affect the final test results. The current manual cutting method cannot achieve high-precision and accurate cutting. There is an urgent need for a convenient, fast and Cutting device capable of meeting high precision requirements

Embodiment Construction

[0025] The specific method of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0026] Such as figure 1 As shown, a special cutting device for Overlay specimens, including telescopic bolt 1, sliding side plate 2, side plate slide rail 3, vertical cutting reserved cutting seam 4, rotatable upper clamp 5, flange buckle 6, cross-cutting clamp 7. Cutting seam reserved for cross cutting 8, blade base slide rail 9, cutting blade 10, blade guard 11, blade base 12, blade bracket 13, lateral movable support 14, lateral control motor 15, lateral pressure bar 16, lateral Slide bar 17, longitudinal control motor 18, longitudinal pressure bar 19, vertical cutting fixture 20.

[0027] Such as figure 2 As shown, the vertical cutting fixture 20 fixes the specimen through two side plates. The plate 2 is placed on the test piece, the displacement range of the sliding side plate 2 on the side plate slide rail 3 is 0 ~ 10mm, there are ver...

Abstract

The invention discloses a special cutting device for an Overlay test piece. The special cutting device comprises a support base, a fixing mold, a maneuvering device and a cutting component, wherein a transverse cutting clamp, a longitudinal cutting clamp and the maneuvering device are fixed on the support base, a transverse control motor and a longitudinal control motor can pull and push a pressing rod so as to control the displacement of a cutter blade base and the transverse control motor on a cutter blade base slide rail, so that the cutter blade position is adjusted to control the cutting process. According to the device, a rotary compaction test piece or a punching and core drilling test piece can be accurately cut into the geometric dimension required by an Overlay Test, so that redundant operation can be greatly reduced, and the device is simple, convenient and flexible to control.

Description

technical field [0001] The invention relates to the research field of road engineering materials, in particular to a special cutting device for Overlay test pieces. Background technique [0002] Studying the anti-cracking performance of asphalt mixture is not only beneficial to solve problems such as cracks in asphalt pavement, but also has great significance for prolonging the service life of asphalt pavement. [0003] Among the many cracking diseases of asphalt pavement, reflective crack is one of the main forms of failure, and the research on reflective crack by domestic and foreign scholars has never stopped. Among them, the Overlay Test can accurately simulate the action process of reflective cracks in the pavement structural layer, and is favored by many scholars. However, ruler measurement and manual cutting machine cutting are generally used in the production of Overlay specimens, which not only cannot guarantee the accuracy of the geometric dimensions of the specim...
