[0074] The sand powder separator 6 includes a casing 63 , a powder outlet duct 4 and a circulating fan 65 .

[0075] The casing 63 is cylindrical. The casing 63 is a closed structure, that is, the remaining parts are closed except for the provided mouth. The casing 63 is provided with a supporting stand 66 . The supporting stand 66 is ...

Embodiment 2

[0095] Embodiment two, the difference with embodiment one is:

[0096] see Figure 9 , The bottom of the casing 63 is also provided with a double parallel power line 61 and a lamp 2 connected to the double parallel power line.

[0097] see Figure 12 The double-parallel power cord 61 includes two core wires 611 and an insulating layer 612 insulatingly wrapping the two core wires 611 . The core wire 611 is a copper wire. The insulating layer 612 is plastic.

[0098] see Figure 9 , The lamp 2 includes a circuit board 21 , a light source 22 and two lamp pins 23 . The circuit board 21 is an existing structure. The light source 22 is an LED. The light source 22 is connected to the circuit board 21 . The connection mode of the light source 22 and the circuit board 21 is existing. The lamp pins 23 are used for introducing electricity to the light source 22 to make the light source 22 emit light.

[0099] see Figure 10 , The lamp base 23 includes a fixed piece 231 , a mov...

Embodiment 3

[0120] Embodiment three, the difference with embodiment two is:

[0121] see Figure 18 , one end of the heat conduction sleeve 734 and one end of the heat sink 71 are sealed against the sealing plate 74 , that is, both the heat conduction sleeve and the heat sink can slide relative to the seal plate 74 . The other end of the heat conducting sleeve 734 and the other end of the radiator 71 are sealed and connected together through the annular liquid storage bag 75 . The annular liquid storage bag 75 is filled with heat-insulating liquid, and the heat-insulating liquid makes the annular liquid storage bag 75 in an elastically expanded state. When the temperature is below 25° C., a sealed cavity 76 is formed among the heat conducting sleeve 734 , the sealing plate 74 , the radiator 71 and the annular liquid storage bag 75 . The sealed cavity 76 communicates with the annular liquid storage bag 75 .

[0122] When in use, the annular liquid storage bag 75 is positioned above the ...

Abstract

The invention relates to the technical field of automobile axle manufacturing, and discloses a stirring rolling machine for automobile axle sand mold manufacturing and with a sand-powder separation-type feeding mechanism. The stirring rolling machine comprises a stirring rolling machine body, a feeding machine with a discharging outlet and a sand-powder separation machine. The sand-powder separation machine comprises a circulating fan, a powder outlet channel with a powder outlet, a powder outlet air pipe and an enclosure of a closed structure. A material scattering mechanism, air outlets, a sand outlet, a sand inlet located above a material scattering rotary table, and an air inlet located below the material scattering rotary table. The air outlets communicate with the powder outlet air pipe through an air tube. The powder outlet air pipe is connected with an inlet of the circulating fan, and an outlet of the circulating fan is connected with the air inlet together. The lower end of the air tube communicates with the powder outlet. The sand inlet is in butt joint with the discharging outlet. The stirring rolling machine has the advantages that sand-powder separation can be achieved before sand mixing, the amount of raised dust generated in the separating process is small, and sand blocks can be crushed in the sand mixing process; and the problems that the amount of the raised dust is large in the sand-powder screening process and the sand blocks cannot be crushed in the sand mixing process are solved.

Description

technical field [0001] The invention relates to the technical field of manufacturing automobile axles, in particular to a stirring and rolling machine for making automobile axle sand molds equipped with a sand-powder separation type feeding mechanism. Background technique [0002] There are mainly two methods of manufacturing automobile axles: forging and casting. There are two main types of casting molds: one is a metal mold and the other is a sand mold. In the sand mold making process, it is necessary to mix sand and curing agent together (hereinafter referred to as sand mixing) so that the sand mold can be fixed and shaped. In the existing sand mold making process, sand mixing is done manually, so the worker's Labor intensity is high. If agglomerated sand 9 (hereinafter referred to as sand block) is found during the sand mixing process, it is broken manually. In order to reduce the labor intensity during sand mixing, some manufacturers also use mixers to mix sand and u...
