As shown in fig. 1-3, the desanding device for the buffer guide sleeve casting comprises a workbench 2 arranged on a bracket 1, a vertical plate 5 arranged at the rear end of the workbench 2, and a horizontal plate 51 arranged at the top of the vertical plate 5; the horizontal plate 51 is provided with a push-down element 6, the push-down element is preferably an air cylinder, in this embodiment, the push-down element 6 is fixedly mounted on the top surface of the flat plate part 51, and a push head 61 is arranged after the push end of the push-down element 6 passes through the horizontal plate 51 downwards. The vertical plate 5 is provided with a striking unit 4, the striking unit 4 comprises two striking blocks 49 which are arranged opposite to each other in the horizontal direction, a link mechanism which is arranged corresponding to each striking block 49, and a driving mechanism which drives the two link mechanisms to act, and the two striking blocks 49 approach or separate under the driving of the link mechanisms. During specific construction, a poured guide sleeve casting 7 wrapped with a sand mold is placed on the workbench 2, the casting 7 is located in the middle of the two impact blocks 49, namely the two impact blocks 49 are symmetrically arranged on the left side and the right side of the casting 7, then the push-down element 6 is started, the pressure head 61 of the push-down element is tightly pressed at the riser of the casting, the casting 7 is stabilized on the workbench 2, then the driving unit is started, under the action of the driving mechanism, the two link mechanisms synchronously act, the two impact blocks 49 quickly impact the casting 7, under the action of the impact blocks 49, the sand mold wrapped on the casting 7 is broken, and the demolding and sand falling operation of the casting 7 is completed.
In this embodiment, the driving mechanism includes a sliding rod 45, a cam 41, a spring 44, and a connecting block 46, the sliding rod 45 is preferably a cylindrical rod structure, the sliding rod 45 is slidably disposed through the upright plate 5, the connecting block 46 is disposed at the front end of the sliding rod 45, the link mechanism is mounted on the connecting block 46, a stopper 43 is disposed at the rear end of the sliding rod 45, the spring 44 is sleeved at a position of the sliding rod 45 between the upright plate 5 and the stopper 43, the cam 41 and the stopper 43 are correspondingly disposed, and the cam 41 is matched with the motor 42. The motor 42 drives the cam 41 to rotate, the cam drives the stop 43 to further push the slide rod 45 to move forwards, when the far end of the cam 41 contacts the stop 43, the slide rod 45 moves forwards for the maximum distance, and at the moment, the two impact blocks 49 approach to operate, so that the impact operation on the casting 7 is realized. When the cam 41 rotates 180 degrees, that is, the far end of the cam is far away from the stop 43, the near end of the cam 41 corresponds to the stop 43, and because the spring 44 is arranged on the sliding rod 45, the sliding rod 45 moves back and returns under the action of the spring 44, and at this time, the two impact blocks 49 move away. Therefore, under the combined action of the cam 41 and the spring 44, the sliding rod 45 moves back and forth in a reciprocating manner, so that the connecting rod mechanism is driven to act, and finally the two impact blocks 49 are driven to synchronously shake and knock the casting 7 in a reciprocating manner in the horizontal direction. In this embodiment, the link mechanism includes a first push rod 47 and a second push rod 48, the rear end of the first push rod 47 is hinged to the connecting block 46, the front end of the first push rod 47 is hinged to the rear end of the second push rod 48, in an initial state, an included angle between the first push rod 47 and the second push rod 48 is an obtuse angle, the striking block 49 is fixedly mounted at the front end of the second push rod 48, the middle position of the second push rod 48 is hinged to a support frame 52 provided on the vertical plate 5, in this embodiment, the number of the support frames 52 is two, the two support frames 52 are provided at the left and right ends of the vertical plate 5, it is ensured that the two support frames 52 and the two link mechanisms are in one-to-one correspondence, and during mounting, each second push rod 48 is hinged to. When the driving mechanism works, the two link mechanisms synchronously act to enable the impact block 49 to synchronously reciprocate, finally, the action force acts on the sand mold of the casting 7 to impact the sand mold, so that the sand mold is damaged, shaked and demolded.
In this embodiment, in order to ensure that the two impact blocks 49 act on the same horizontal plane, a circumferential limiting structure is disposed between the sliding rod 45 and the vertical plate 5, specifically, the sliding rod 45 is axially provided with a sliding groove 451 on a side surface thereof, two ends of the sliding groove 451 penetrate through front and rear end surfaces of the sliding rod 45, the vertical plate 5 is provided with a protruding block 53 corresponding to the sliding groove 451 through a hole wall of the through hole for the sliding rod 45 to pass through, and the protruding block 53 is inserted into the sliding groove 451. When the sliding rod 45 moves, the projection 53-the sliding groove 451 forms a guiding structure to limit the rotation of the sliding rod 45, so that the sliding rod 45 can only move back and forth along a horizontal straight line, the action tracks of the two link mechanisms are ensured to be positioned in the same horizontal plane, and the two impact blocks 49 are ensured to be always kept in a right-facing state.
In this embodiment, in order to improve the impact strength of the impact blocks 49 on the sand mold, conical protrusions are respectively protruded on the opposite side surfaces of the two impact blocks 49.
In this embodiment, for in time collecting the shakeout, workstation 2 includes dull and stereotyped portion 21, dull and stereotyped portion 21 is equipped with the shakeout hole in the position department under pressure head 61, evenly be equipped with a plurality of bearing rollers 22 from left to right in the shakeout hole. The supporting rollers 22 and the flat plate part 21 are arranged in parallel and level, so that the casting 7 can be conveniently moved between the flat plate part 21 and the supporting rollers 22, and fallen gravel falls through a gap between two adjacent supporting rollers 22. The support 1 is provided with a guide cover 3 corresponding to the shakeout hole at the position below the shakeout hole, the bottom end of the guide cover 3 is provided with a sand discharge port, and the sand discharge port corresponds to a collection box. And the fallen sand is convenient to collect in time.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
