Embodiment Construction

[0041] The specific working method of the present invention will be described in detail below with reference to the accompanying drawings.

[0042] like figure 1 As shown in the figure, a semi-automatic demolding machine for large and small Marshall specimens includes a metal frame 1 on which a hub 3, a master controller 4, a hydraulic press 6, a hydraulic press motor 31, an electric mechanical arm 34, and a large and small Marshall specimen electric The card-block integrated machine 35, the hub transmits the signal of the signal control button to the master controller 4 through the signal line, and then transmits the instruction to each component.

[0043] like figure 2As shown in the figure, a large Marshall test piece magnetic top block 23 and a small Marshall test piece magnetic top block 22 are provided with a non-penetrating groove in the middle, and the diameter of the middle groove 36 is matched with the diameter of the hydraulic press ejector rod 7, so as to In ord...

Abstract

The invention belongs to the field of road engineering materials, in particular to a semi-automatic demoulding integrated machine for large and small Marshall test pieces and a demoulding method. Including metal frame, large and small Marshall test piece electric clamp all-in-one machine: set on one side of the upper surface of the metal frame, including switchable large Marshall test piece clamps and small Marshall test piece clamps; test specimen storage: located in the metal frame The other side of the test piece; electric mechanical arm: located between the large and small Marshall test piece electric clamp integrated machine of the metal frame and the test piece storage place; hydraulic rod drive mechanism: located in the metal frame, and located in the large and small Marshall test piece electric clamp block integrated Below the machine; the main controller: the control of the electric clamping block integrated machine, the electric mechanical arm and the hydraulic rod driving mechanism of the large and small Marshall specimens is realized through the signal control button. The advantages of the invention are that the human error of manual demoulding is avoided, the workload of demoulding is reduced, and the demoulding switching process of the large Marshall test piece and the small Marshall test piece is simplified.

Description

technical field [0001] The invention belongs to the field of road engineering materials, in particular to a semi-automatic demoulding integrated machine for large and small Marshall test pieces and a demoulding method. Background technique [0002] At present, there are mainly two kinds of Marshall specimens, one is the small Marshall specimen with a diameter of 101.6mm and a height of 63.5mm; the other is a large Marshall specimen with a diameter of 152.4mm and a height of 95.3mm. Because the common Marshall test piece demoulding devices on the market are mostly manual alignment, and the demoulding workload is large, the demoulding error and the impact on the sample are relatively large. In the market, the demoulding process of Damascus and Little Martens is relatively cumbersome, and the switching of demolding type molds is more complicated. [0003] When demoulding the Marshall test piece, the influence on the test piece should be minimized, which needs to be avoided as ...
