Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of aluminum ingot casting, and particularly relates to a knocking and demoulding device for an aluminum ingot forming mold. Background Art
[0002] Aluminum ingot casting is a production process in which aluminum ore raw materials or crushed recycled aluminum are melted into aluminum liquid in a smelting furnace, and then evenly distributed and cast into the forming mold of the ingot casting machine. After cooling and shaping, the aluminum ingot is demolded to produce the aluminum ingot. The tail of the ingot casting machine is generally equipped with a demolding hammer device. Traditional demolding hammer devices are mostly mechanical structures that are synchronously lifted with the circulating chain of the ingot casting machine and then freely fall and hammer. The hammering force is relatively weak, which can easily lead to unfavorable demolding. At present, a small number of ingot casting machines also use pneumatic hammers, but the hammer structure design is unreasonable. The hammer vibrates too much during hammering, resulting in a high failure rate of the hammer cylinder, a short service life of the cylinder, increased maintenance workload, and increased cylinder replacement costs, affecting the production efficiency of the ingot casting machine.

The ingot casting machine is of the prior art and will not be described in detail here.
[0025] A set of induction meter components is arranged on the outer side of each of the left and right ends of the gear shaft, and a total of two sets of induction meter components are arranged, and two sets of pneumatic knocking hammer components are symmetrically arranged above the tail bracket.
[0026] The induction counting component includes a counting tooth disc 6 coaxially fixed on the end face of the gear shaft, which is a radial disc structure with a plurality of trigger tooth bars 7 arranged at equal intervals around the periphery, and a proximity switch 8 fixedly installed on the tail bracket and capable of detecting each trigger tooth bar.
[0027] The pneumatic knocking hammer assembly includes a knocking arm swingably connected to the tail bracket, a knocking hammer 9 installed at the lower end of the knocking arm for knocking each forming mold, a knocking cylinder 10 connected to the upper end of the knocking arm and driving the knocking arm to swing back and forth, and the knocking cylinder being installed on the tail bracket.
[0028] The two counting tooth discs and the two proximity switches at both ends of the gear shaft can be adjusted in cooperation to adjust the sensing position or the sensing time, so that the two sets of pneumatic knocking hammer assemblies perform the knocking demolding action with a small time difference, and the two knocking hammers knock the left and right ends of the forming mold in succession each time, which is beneficial to ensure the reliability of demolding.
[0029] The outside of the ingot casting machine is matched with an electric control cabinet (not shown in the figure), the two proximity switches and the two knocking cylinders are electrically connected to the electric control cabinet, and the two proximity switches give knocking signals to the two knocking cylinders by detecting the trigger tooth bars one by one. The electric control cabinet is a prior art, and its internal control circuit is not described in detail.
[0030] Specifically, the knocking arm is composed of a large arm 11 and a small arm 12, the lower end of the large arm is connected to the upper end of the small arm through a damping shaft 13, the upper part of the large arm is rotatably connected to the tail bracket through a bearing seat 14, the upper end of the large arm is connected to the piston rod of the knocking cylinder, and the base of the knocking cylinder is connected to the tail bracket through a mounting seat 15.
[0031] Specifically, the knocking hammer is connected to the lower end of the small arm of the knocking arm through a rubber shock absorber 16. The damping shaft is a 180° limiting damping shaft. The rubber shock absorber and the damping shaft both have a certain damping and buffering effect on the knocking hammer, which avoids the direct return of the reaction force generated by the hard knocking of the knocking hammer to the end of the knocking cylinder, helps to protect the knocking cylinder, reduces the failure of the cylinder, and prolongs the service life of the cylinder. The rubber shock absorber and the damping shaft both belong to the prior art, and their specific settings are not described in detail.
[0032] Specifically, the left and right ends of the gear shaft are rotatably connected to the tail bracket through rolling bearings 17 respectively; the rolling bearings and bearing seats are both vertical outer spherical bearings with seats, and the vertical outer spherical bearings with seats belong to the existing technology, and the specific settings will not be described in detail here.
[0033] Specifically, two sets of demoulding buffer assemblies are installed above the tail bracket, which are symmetrically arranged on the left and right. The two sets of demoulding buffer assemblies are arranged between the two sets of pneumatic hammer assemblies; the demoulding buffer assembly includes a support rod 18 and a spring guide rod. The upper part of the support rod is swingably connected to the tail bracket through a hinge seat 19, and the spring guide rod is connected to the tail bracket through a fixed seat 20.

The guide rod can slide telescopically through the middle of the fixed seat through a sliding sleeve 23. One end of the guide rod is hinged to the upper end of the big arm of the knocking arm through a hinge joint 24. The spring has an elastic thrust on the hinge joint. The other end of the guide rod is threadedly connected to a limiting nut 25 to prevent the guide rod from rebounding and falling out.
[0035] Specifically, a rollable guide roller 26 is also provided at the lower end of the support rod. The lower end of the support rod is close to the starting position of the return section at the lower part of the circulating chain. The lower half of the support rod is an arc-shaped structure that matches the changing section of the circulating chain, and there is a certain gap between the support rod and the forming mold on the circulating chain. The support rod is mainly used to form a certain supporting force on the aluminum ingot in the changing section after the aluminum ingot is demolded from the forming mold, guiding the aluminum ingot to slowly slide down instead of falling directly after demolding from the forming mold. The guide roller also plays a certain rolling guiding role on the aluminum ingot.
[0036] Specifically, a conveyor chain 27 is provided below the return section of the ingot casting machine's circulating chain to receive and transport the aluminum ingots that fall after demolding. This conveyor chain transports the aluminum ingots in a direction opposite to the return section of the ingot casting machine's circulating chain, transporting the ingots one by one in a direction away from the ingot casting machine. This conveyor chain utilizes existing technology, and its specific configuration will not be detailed here.

Without departing from the scope and spirit of the described embodiments, many modifications and changes are obvious to ordinary technicians in this technical field. Any technical deformation made within the spirit and principles of the present invention falls within the scope of protection of the present invention.
