In this case, four air hammers are taken as an example for explanation. The hammering component comprises two door type hammer frames 7 and a hammer frame pressing plate 8, and four air hammers are assembled. Has pneumatic and electric capability configuration for four air hammer workers to work simultaneously. The air hammer can be adjusted in the front and back direction and the left and right direction of the horizontal position, and the position of the air hammer can be independently adjusted up and down to meet the requirement of a casting hammering process. The maximum striking distance of the air hammer is 140mm, and the recommended striking distance is 70 mm. The position of the air hammer on the air hammer cross beam 6 is adjustable, the height of the air hammer is adjustable, and particularly the height of the whole air hammer can be adjusted by adjusting the heights fixed by different bolts. The hammering frequency (0.6MPa) was 20 times/sec. The casting is placed on the workbench positioning support and does not need to be compressed, then the tool is moved into a hammering area provided with four air hammers, and the pneumatic hammer head is used for hammering from top to bottom. The high frequency hammering separates the sand core from the casting surface and cracks into pieces. And (5) when the hammering time reaches the working table to the moving-out position, waiting for the next sand shaking working procedure.

The air hammer can produce very big noise when hammering the foundry goods, can reach more than 108 decibels at most, and the operator can't normally work, consequently must design an effectual soundproof room, makes its work noise reach below 85 decibels (measuring 1 meter away from the machine) of national relevant standard requirement. This soundproof room places the waste sand belt below owing to must leave the opening, therefore has certain noise to spill over, has holistic panel beating room in this equipment outside in addition, can reduce the noise.

The sound-proof room is a multi-layer combined type mechanism, the outer layer is a frame steel plate, the inner layer is a silencing steel orifice plate, and sound-proof and sound-absorbing materials are filled between the sound-proof room and the inner layer.

As shown in fig. 6-9, the sand shaking station 02 includes a base frame 021, a shaking frame 022 is installed on the base frame 021, and the shaking frame 022 is installed and fixed by a support fixing plate 023. The shaking frame 022 is provided with two vibrating motors and a positioning tool obliquely arranged, and the positioning tool comprises a mounting base tool plate 027 and a positioning head 028 for positioning the whole auxiliary frame; the two vibrating motors are connected with a vibrating frame 024. The base frame of the machine is formed by welding steel plates and sectional materials and mainly plays a supporting role, and the support, the shaking frame, the motor driving part and the sand receiving hopper are fixed on the base frame. In addition, the base is directly fixed on the workshop ground through six rubber damping springs, and the vibration of the shaking frame acting on the base when the shaking motor works is relieved and absorbed. The lower part of the base is provided with a sand receiving chute so as to collect falling sand blocks and broken sand.

The vibration frame is connected with the obliquely arranged positioning tool and vibrates the whole auxiliary frame 06 on the positioning tool, the sand cores collide and rub with each other and the inner wall of the whole auxiliary frame, sand grains on the surfaces of the sand cores gradually fall off and flow out of the cavity from a gap of the whole auxiliary frame. The bidirectional amplitude is 15mm, and the vibration frequency is 24 times/second, and can be properly adjusted. The broken sand that flows out is sent to big waste sand case and is concentrated and collected through receiving the conveyer belt 05 that the sand chute slided to the bottom. In the part, because the working state is high-frequency vibration, each part including the fastening piece always bears high-strength vibration load, the strength and anti-loosening problems of parts and the fastening piece must be paid special attention, and the high reliability of the operation of the whole machine can be ensured only if the problems are solved. According to the positioning seat and the air bag pressing mechanism specially designed for the positioning point of the workpiece, the workpiece can be kept stable and not loosened all the time in the operation process, and the positioning surface and the pressing surface are ensured not to be crushed and abraded.

The left side and the right side of the shaking frame are respectively and correspondingly provided with a conventional left air bag pressing mechanism 029 and a conventional right air bag pressing mechanism 030.

The shaking frame is fixed on the base frame through a plurality of rubber damping springs, and the two vibrating motors are fastened and assembled together through a pull rod to form a rigid frame; when the vibration motors work in the same direction, the shaking frame is driven to do elliptic high-frequency vibration together; a sound-proof cover is arranged on the decoring machine.

And (3) placing the hammered workpiece on a positioning device of the sand shaker, then closing the protective door (if the protective door is provided), and pressing the workpiece by the pneumatic pressing mechanism. Through the vibrations of two vibrating motor that link, drive frock high frequency vibrations together that floats, make the inside psammitolite of work piece acutely strike the fragmentation, the broken sand flows smoothly from work piece bottom sand outlet.

Because the vibration is elastic vibration and a secondary vibration isolation measure is carried out between the ground and the vibration body, most of vibration energy is transmitted to the casting and the sand core without influencing the equipment.

The overall process is summarized as follows: firstly, a casting is correctly placed on a positioning component on a workbench of a hammering station 01 by a manual or robot paw, then the workbench is moved in place, a jacking air bag assembly enables the workbench to upwards float to prop against a rack for limiting, an air hammer striking point is adjusted to a proper position on a casting riser, then the corresponding air hammer is started to strike for tens of seconds, under the action of high-frequency hammering force, a sand core is theoretically decomposed into a plurality of sand cores or even dozens of sand cores and separated from the inner wall of the casting, the decomposed sand core blocks have swinging gaps in a cavity, meanwhile, part of the sand cores outside can fall off, the striking is stopped, and the workbench is moved out after falling in place. Then, the workpiece is taken out and correctly placed on a positioning tool of the sand shaking station 02, the air bag pressing mechanism presses the workpiece, the casting is shaken at high frequency under the driving of the two linkage vibrating motors, the sand cores collide and rub with each other, sand grains on the surface of the sand core blocks gradually fall off, and the sand grains flow out of the cavity from the gap. After sand shaking is finished, the pressing rod is loosened, the equipment protective door (if any) is opened, and then the workpiece can be taken away to the next step. The whole hammering and sand shaking whole-course falling sand block and broken sand are sent out by two waste sand conveying belts arranged at the bottom, loaded in a waste sand box and carried away by a forklift after being filled.

hammering and shakeout are divided into two parts, and the decoring machine is divided into two independent parts, namely a hammering station 01 and a sand shaking station 02, so that the core removing machine can be suitable for castings with larger volumes and structures.

In addition, change in the hammering station 01 and shake sand station 02 in to the change of the concrete installation fixed mode of sub vehicle frame and change of hammering, shake sand mode, improve the convenience of getting and putting the piece and improve desanding effect and efficiency.
