The mold is characterized in that cooling air holes in a bottom mold are moved for 10 mm in outwards; heat-insulation grooves are formed in positions, 5 mm from the cooling air holes, of a back cavity of the bottom mold, and are 8 mm from the surface of a cavity; and the width of each heat-insulation groove is set to 8 mm. A circumference arrangement range of the heat-insulation grooves needs to be larger than the widths of the spokes, and the number of the heat-insulation grooves is defined by the number of the spokes. Heat-preservation asbestos is arranged in each heat-insulation groove, thereby further strengthening heat-insulation and heat preservation functions. One air hole is added based on the prior art, thereby increasing the cooling area and improving the cooling intensity.

Central Heat-insulation Hole Structure for Wheel Water-cooling Mold

A central heat-insulation hole structure for an aluminum wheel low-pressure water-cooling casting mold. The structure includes a top mold and a central heat-insulation hole. A split unit structure including a top mold and central flange loose pieces is changed into a non-split integrated top mold. Besides, a circle of uniformly distributed heat-insulation holes are thrilled in a circumferential direction of the position of a mold split unit parting surface of the original top mold and the central flange loose pieces. The diameter of each heat-insulation hole is 8 mm, the size of a wheel flange defines the number of the heat-insulation holes and the diameter of circumference of the heat-insulation holes distributed in the integrated top mold, and in order to ensure the service life and water cooling and heat insulation effects of the mold, the depth of each heat-insulation hole from the surface of a cavity is more than 20 mm.

DEVICE FOR REMOVING TOOL JOINT EDGE BURRS OF WHEEL

A device for removing tool joint edge burrs of a wheel comprises a frame, a base, first guide rails, a first movable plate, a first ball screw, a longitudinal motor, a transverse motor, second guide rails, a second ball screw, a movable plate II, an electric cylinder, a mobile roller bed, a circle center measuring sensor, an inner bearing, a shaft, a sleeve, guide keys, a hollow shaft, a pyramid cutter, outer cylinders, a left blade, a right blade and the like. The device is configured to simultaneously remove tool joint edge burrs from an outer rim and a cap slot edge and is used for automatic continuous production; by integrating inner and outer burr removing cutters, not only is the space saved, but also inner and outer independent feeding and independent rotation are realized; the inner and outer cutters have higher coaxiality, and the burr removing effect is improved. 1wherein the shaft is matched with the inner bearing, the sleeve is mounted outside the inner bearing, four key slots are formed in the outer wall of the sleeve, and each of the key slots is circumferentially spaced 90 degrees from the adjacent key slots; four guide key slots are formed in the inner wall of the hollow shaft, each of the guide key slots is circumferentially spaced 90 degrees from the adjacent guide key slots, one end of each guide key is mounted on the sleeve, and another end of each guide key is matched with a guide key slot; the outer wall of the hollow shaft is matched with the outer bearing, the outer bearing is mounted in the bearing seat, and the bearing seat is fixed on the outer movable plate; andwherein the inner motor drives the shaft to drive the pyramid cutter to rotate, and tool joint edge burrs are removed from the edge of a cap slot; the outer motor drives the small gear to rotate, the small gear drives the large gear to rotate, and when the large gear rotates, the combination formed by the hollow shaft and the sleeve also rotates, and does not interfere with the ...

Method for curing heavy metals in coal gangue by using microorganisms

A method for solidifying a heavy metal of coal gangue by using a microorganism, comprising: measuring the heavy metal ion content of gangue to be filled, selecting a strain according to the measurement result, and formulating an inoculant; arranging inoculant injecting pipes in a goaf; during filling, spraying the inoculant on gangue by means of a nozzle so as to perform solidification treatment; and after filling is completed, spraying the inoculant to a water accumulation place by means of an inoculant injecting pipeline to achieve secondary solidification. By means of the method for solidifying the heavy metal of coal gangue by using the microorganism of the present invention, the present invention performs microorganism attachment treatment before the filling of gangue, can directly solidify the heavy metal of gangue in the goaf, and after the filling is completed and when there is water in the goaf, can also use an inoculant injecting net to complement the inoculant, thereby achieving secondary solidification, reducing the migration pollution of the heavy metal ions, having a good solidification effect and little pollution, and is easy to implement and popularize.

Comprehensive supporting method for a fully mechanized mining face of a coal mine

Sub-frame cleaning and blow-drying device

The present disclosure relates to a sub-frame (13) cleaning and blow-drying device, comprising a rack (1), a water tank (2), a bottom lifting assembly (3, 4, 5), supporting assemblies (14, 15, 16), a top lifting assembly (17, 18, 19, 20), a rotating assembly (21-25), an expanding and cleaning-off assembly (31-34) and a blow-drying device (7-11). Expanding assemblies (31-34) expand to be connected with vehicle body mounting holes, compressed air is blown into the vehicle body mounting holes by air outlets and is blown into a cavity of a sub-frame (12) to clean off aluminum scraps and residual sand in the cavity of the sub-frame (12), the rotating assembly (21-25) drives the expanding and cleaning-off assembly (31-34) and the sub-frame (12) to do rotation movement to perform secondary cleaning, so that the aluminum scraps and the sand remaining inside the cavity can be cleaned off, and the sub-frame cleaning and blow-drying device can be flexibly adjusted by a position adjusting assembly (44, 46, 47, 48 und 26, 29) according to different types of sub-frames and is strong in universality.
