Description

Technical Field

[0001] The utility model belongs to the technical field of magnesium alloy processing equipment, in particular to a debris cleaning device for magnesium alloy die-casting. Background Art

[0002] When die-casting magnesium alloy materials, the magnesium alloy blank must maintain a certain processing temperature. When the workpiece is formed and demolded, some debris and slag will inevitably be produced. These debris come from the blank. After extrusion and tearing, there is no passivation layer on the surface. When it comes into contact with air, the active metal in it is prone to chemical reactions. In addition, the debris falling off from the mold itself has a certain temperature. When the temperature of the debris accumulation rises, it is easy to burn. The combustion caused by magnesium alloy debris is a Class D metal combustion and is not easy to extinguish.

[0003] In addition, magnesium alloy debris is very easy to ignite. Therefore, when sporadic magnesium alloy debris is burning, it should be extinguished in time to prevent it from igniting the remaining magnesium alloy debris. This is particularly important for preventing magnesium alloy debris fires.

[0037] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0038] The present invention will be further described below with reference to the accompanying drawings:

[0039] like Figures 1-9As shown, a debris cleaning device for magnesium alloy die-casting molding includes a sand trough 1, which is used to hold yellow sand for cooling and extinguishing the debris, and is also used to receive the fallen magnesium alloy debris; the magnesium alloy debris still has a relatively high temperature at the initial stage of falling, and some are even close to reaching the critical state of combustion. Therefore, according to the size of the extrusion equipment, a sand trough 1 is set at the bottom of the blanking material, and yellow sand is used to cool and flame retard the fallen magnesium alloy metal debris.

[0040] The fixed side panel assembly 2 is fixedly connected to one side of the sand trough 1. A debris cleaning streamline 3 is fixedly fitted between the fixed side panel assembly 2 and the sand trough 1. The fixed side panel assembly 2, the sand trough 1 and the debris cleaning streamline 3 need to be customized according to the size of the blanking space of the main equipment used. The fixed side panel assembly 2 plays the role of fixedly connecting the debris cleaning streamline 3 and the sand trough 1. The debris cleaning streamline 3 is fitted between the sand trough 1 and the fixed side panel assembly 2 to collect magnesium alloy debris after fire extinguishing and cooling.

[0041] The cleaning auger assembly 5 is matched in the sand trough 1, and is used to stir the yellow sand to cool the debris and extinguish the fire; the reciprocating sliding assembly 4 is matched on the other side of the sand trough 1, and forms a matching mechanism with the fixed side plate assembly 2 and the cleaning auger assembly 5; one end of the cleaning auger assembly 5 is hinged to the reciprocating sliding assembly 4, and the other end is matched with the fixed side plate assembly 2. It will rotate during the movement, and use its own structure to stir the yellow sand during the rotation to cover the falling debris to extinguish the fire and cool it.

[0042] The transmission mechanism 7 is fixed on one side of the reciprocating sliding assembly 4 and is used to drive the reciprocating sliding assembly 4 to drive the cleaning auger assembly 5 and the fixed side plate assembly 2 to move, and one end of the transmission mechanism 7 is equipped with a motor 8; the transmission mechanism 7 is composed of a chain and a pair of sprockets, one of which is driven by the motor 8 and rotates continuously; the reciprocating sliding assembly 4 is anchored to the chain of the transmission mechanism 7 through a connecting piece. During the continuous rotation of the transmission mechanism 7, the reciprocating sliding assembly 4 is pulled to perform reciprocating linear motion, so that the reciprocating sliding assembly 4 pulls the fixed side plate assembly 2 and the cleaning auger assembly 5 that cooperate with it to move back and forth, continuously processing the magnesium alloy debris that falls into the sand trough 1.

[0043] The rotary push plate assembly 6 is fixed between the reciprocating sliding assembly 4 and the fixed side plate assembly 2, and is a matching mechanism with the cleaning auger assembly 5. It is used to cooperate with the cleaning auger assembly 5 to form a conveying channel to clean and convey the magnesium alloy debris to the debris cleaning streamline 3 for discharge. Although the cleaning auger assembly 5 is an auger structure, it lacks a fence. During its rotation, it can only flip or push the debris a certain distance. However, the debris in the sand trough 1 will gradually increase during the processing process. Therefore, a rotary push plate assembly 6 is added. The rotary push plate assembly 6 is used to surround the side of the cleaning auger assembly 5 to form an auger conveying device. While reciprocating to collect magnesium alloy debris, the debris in the sand trough 1 is pushed and conveyed to the debris cleaning streamline 3 and then discharged along the debris cleaning streamline 3.

[0044] As an embodiment of the present invention, Figure 2-4 As shown: the fixed side plate assembly 2 includes a sand trough fixing plate 21 for fixed installation. The sand trough fixing plate 21 is fixed to the magnesium alloy forming equipment. A pair of side plate bearing seats 22 are installed on the side wall of the sand trough fixing plate 21. The two side plate bearing seats 22 are fixed to the two end positions of the sand trough fixing plate 21 by bolts. A sliding rod 23 is installed between the two side plate bearing seats 22. A sliding support plate 24 is slidably fitted on the sliding rod 23 through a linear bearing. A fixed connecting plate 25 is fixed to the upper end surface of the sliding support plate 24. An auger limiting plate 26 is fixed to the other end of the fixed connecting plate 25, and the auger limiting plate 26 and the cleaning auger assembly 5 are a matching mechanism. The auger limiting plate 26 serves as a support and limiting structure for the cleaning auger assembly 5, and works together with the reciprocating sliding assembly 4.

[0045] As an embodiment of the present invention, Figure 2 、 Figure 5 and Figure 8As shown: the reciprocating sliding assembly 4 includes a linear rail slider assembly 41 fixed on the side wall of the sand trough 1 away from the fixed side plate assembly 2, and a sliding limit plate 42 is slidably matched on the linear rail slider assembly 41. In order to increase the stability of the sliding limit plate 42, the slider is provided as a pair. The sliding limit plate 42 is fixed to the pair of sliders by bolts. An auger mounting seat 44 is fixed to the upper end surface of the sliding limit plate 42. The auger mounting seat 44 and the sliding limit plate 42 are fixed by bolts, and the auger mounting seat 44 and the cleaning auger assembly 5 are a matching mechanism. An auger swing shaft rod 45 is provided at the matching position of the auger mounting seat 44 and the cleaning auger assembly 5. The cleaning auger assembly 5 itself needs to rotate along its axial direction, and the auger swing shaft 45 is hinged to one end of the cleaning auger assembly 5, so that the cleaning auger assembly 5 can rotate around the auger swing shaft 45, thereby adjusting its position. A waist hole 421 is provided on the end wall of the sliding limit plate 42, and a transmission connecting plate 43 is slidably fitted in the waist hole 421, and the other end of the transmission connecting plate 43 is fixed to the transmission mechanism 7, and the transmission connecting plate 43 is fixed to the chain of the transmission mechanism 7. In the process of its axial movement with the chain, its position in the waist hole 421 will change, and the set waist hole 421 can prevent the mechanism from self-locking.

[0046] As an embodiment of the present invention, Figure 4-Figure 6 As shown: the cleaning auger assembly 5 includes a rotating shaft 51 whose two ends respectively cooperate with the auger limit plate 26 and the auger mounting seat 44, and a spiral spiral screen plate 52 is fixed on the rotating shaft 51. The screen provided on the spiral screen plate 52 can allow yellow sand to pass through.

[0047] As an embodiment of the present invention, Figure 2-6 As shown: a limiting groove is provided at the cooperation place of the auger limiting plate 26 and the rotating shaft 51, and a rolling bearing seat 54 that cooperates with the auger mounting seat 44 and the limiting groove is fixed at both ends of the rotating shaft 51. The limiting groove limits the lateral displacement of the rolling bearing seat 54, and the end of the rotating shaft 51 and the auger mounting seat 44 is provided with an auger swing shaft rod 45 for rotating the rotating shaft 51 up and down. The rolling bearing seat 54 rotates with the auger mounting seat 44 through the auger swing shaft rod 45, and the corresponding limit on the auger limiting plate 26 The positioning slot is provided with a spring hole, in which a compression spring 28 is fitted; a spring pressure cover 27 for limiting the compression spring 28 is fixed to the upper end surface of the auger limiting plate 26; one end of the rotating shaft 51 extending out of the auger limiting plate 26 is equipped with an elastic telescopic wheel assembly 55, and the elastic telescopic wheel assembly 55 forms a matching mechanism with the sand trough fixing plate 21; the auger swing shaft 45 cooperates with the rotating part rolling bearing seat 54 of the rotating shaft 51, so that the rotating shaft 51 can be lifted around its matching end with the auger mounting seat 44.

[0048] During operation, the transmission mechanism 7 is driven by the motor 8, and the chain provided therein moves continuously on the two sprockets. During this process, the transmission connecting plate 43 fixed on the chain moves along with the chain. When the chain passes the sprockets at both ends, the transmission connecting plate 43 rotates along with the chain around the waist hole 421 opened on the sliding limit plate 42, thereby changing the direction of the pulling force applied to the sliding limit plate 42, thereby pulling the sliding limit plate 42 to perform reciprocating linear motion on the linear rail slider assembly 41;

[0049] One end of the cleaning auger assembly 5 is engaged with the auger mounting seat 44, and moves along with the sliding limit plate 42 under the drive of the sliding limit plate 42. At the same time, the auger limit plate 26, the fixed connecting plate 25 and the sliding support plate 24 engaged with the other end of the cleaning auger assembly 5 also slide synchronously on the slide rod 23 under the pull;

[0050] During this process, the compression spring 28 provided in the auger limit plate 26 supports the rotating shaft 51, so that the elastic telescopic wheel assembly 55 fitted at one end of the rotating shaft 51 is continuously in contact with the sand trough fixed plate 21. During its movement, the elastic telescopic wheel assembly 55 frictionally rolls, thereby driving the rotating shaft 51 to rotate around its own axis. In this way, when the rotating shaft 51 rotates, the spiral screen plate 52 continuously flips the yellow sand in the sand trough 1, thereby burying the magnesium alloy debris that falls into the sand trough 1, cooling the magnesium alloy debris, and at the same time, it can bury and flame-retard some debris that are about to reach the critical state of combustion, eliminating the risk of combustion in the bud. In addition, the flipping of the spiral screen plate 52 is more conducive to the heat dissipation of the yellow sand, thereby maintaining its cooling effect on the magnesium alloy debris.

[0051] As an embodiment of the present invention, Figure 6-7 As shown: the sand trough fixed plate 21 is provided with a lifting limit roller 211 and a pressing limit roller 212 for cooperating with the elastic telescopic wheel assembly 55. The front end starting section of the lifting limit roller 211 is provided with an arc slope, and the rear end terminal section is provided with an inclined surface.

[0052] As an embodiment of the present invention, Figure 3 、 Figure 6 and Figure 8 As shown: the rotating shaft 51 passes through one end of the auger limit plate 26, and a polygonal hole is opened at the center position. The elastic telescopic wheel assembly 55 includes a polygonal shaft rod 551 that slides in the polygonal hole. A support spring 552 is provided between the polygonal shaft rod 551 and the bottom of the polygonal hole. A roller 553 is fixed on the polygonal shaft rod 551, and the roller 553 forms a matching mechanism with the lifting limit roller 211 and the pressing limit roller 212.

[0053] During specific operation, the front end of the roller 553 is supported by the support spring 552, and is in close contact with the side wall of the lifting limit roller 211 or the side wall of the sand trough fixed plate 21. When the roller 553 moves to the front end of the lifting limit roller 211, the support spring 552 causes the roller 553 to move forward to the lifting limit roller 211. When the roller 553 moves backward along the lifting limit roller 211, the roller 553 gradually rises to the high point of the lifting limit roller 211. At this time, the rotating shaft 51 is lifted. When the roller 553 moves to the lifting limit roller 211, the rotating shaft 51 is lifted. When the roller 553 reaches the end of the lifting limit roller 211, the roller 553 falls along the inclined surface to the downward pressure limit roller 212 under the action of the compression spring 28. When the roller 553 moves toward the starting end of the lifting limit roller 211 again, the roller 553 rolls along the downward pressure limit roller 212. In this way, the roller 553 drives the rotating shaft 51 to rotate during the movement. When the roller 553 moves backward along the starting end of the lifting limit roller 211, the rotating shaft 51 is lifted. When the roller 553 returns, the rotating shaft 51 is flush with the bottom surface of the sand trough 1.

[0054] As an embodiment of the present invention, Figure 1-6 As shown, the rotating push plate assembly 6 includes a limit rod frame 61 whose ends are respectively fixed to the fixed connecting plate 25 and the auger mounting base 44. When the transmission mechanism 7 drives the reciprocating sliding assembly 4, the cleaning auger assembly 5, and the fixed side plate assembly 2 to move, the mechanical mechanisms of the connecting parts are numerous, and the transmission of force is restricted by the mechanical structure. During the movement, the intermediate structure is prone to fatigue damage. The fixed limit rod frame 61 can connect the reciprocating sliding assembly 4 and the fixed side plate assembly 2 as a whole, making the transmission mechanism 7 more stable when driving them to move together. The limit rod frame 61 is provided with multiple adjustment bolts 62, and the lower ends of the multiple adjustment bolts 62 are commonly fixed to the screen support rod 63. The screen support rod 63 has rollers at both ends, and the rollers are slidably engaged with the screen sliding groove 64. The lower end surface of the screen sliding groove 64 engaged at both ends of the screen support rod 63 is commonly fixed to the screen 65.

[0055] During specific operation, the screen 65 is an arc-shaped structure, which is a matching mechanism with the rotating shaft 51 and the spiral screen plate 52. The position of the screen 65 is adjusted by adjusting the bolt 62 so that it matches the rotating shaft 51 when it is raised, forming a spiral conveying structure. The screen sliding grooves 64 at both ends of the screen support rod 63 enable the screen 65 to rotate around its axis at a certain angle. When the rotating shaft 51 is lifted, the screen 65 rotates to a matching state with the spiral screen plate 52. When the rotating shaft 51 is reset, the screen 65 is reset, and its matching state with the spiral screen plate 52 is released.

[0056] As an embodiment of the present invention, Figure 4As shown: the cleaning auger assembly 5 also includes a flip connecting rod 53 for adjusting the position of the screen 65. One end of the flip connecting rod 53 is rotatably engaged on the outer wall of the rotating shaft 51, and the other end of the flip connecting rod 53 is engaged with a flip connecting seat 68 through a rotating connecting rod, and the flip connecting seat 68 is fixed on the screen sliding groove 64 near one end of the fixed side plate assembly 2.

[0057] During specific operation, when the rotating shaft 51 is lifted, the flip connecting rod 53 on the rotating shaft 51 works together with the rotating connecting rod and the flip connecting seat 68 that cooperate with the flip connecting rod 53 to pull the screen 65 to deflect forward along the screen sliding groove 64, so that the screen 65 cooperates with the spiral screen plate 52. At this time, the spiral screen plate 52 and the inner wall gap of the screen 65 cooperate to form a semi-enclosed mechanism. In the process of its overall component moving toward the tail of the sand trough fixed plate 21, the roller 553 drives the rotating shaft 51 and the spiral screen plate 52 to rotate, and the magnesium alloy debris in the sand trough 1 is transported along the screen 65 to the debris cleaning streamline 3 by spiral conveying, and then discharged through the debris cleaning streamline 3.

[0058] As an embodiment of the present invention, Figure 4 As shown: both ends of the screen support rod 63 are fixed with limit clamps 67 for limiting the screen 65 by bolts. When the screen 65 is pulled and rotated, the limit clamps 67 arranged on both sides can limit the screen 65 so that it will not tilt due to one end being pulled, so that it can only deflect around its axis. A cleaning push plate 66 for chip removal is fixed to one end of the screen 65. When the rotating shaft 51 is lifted, the lifted end is at a different distance from the bottom surface of the sand trough 1 than the other end. The cleaning push plate 66 is provided to make up for the space there, so that after the screen 65 is deflected, the bottom of the cleaning push plate 66 is at the same distance from the bottom surface of the sand trough 1, so that the yellow sand containing magnesium alloy debris can be scraped up and enter the auger conveying structure formed by the screen 65, the rotating shaft 51 and the spiral screen plate 52.

[0059] The working principle and use process of the utility model are as follows: the bottom of the sand trough 1 is inclined, and it is inclined from one end of the debris cleaning streamline 3 to one end of the reciprocating sliding assembly 4. Driven by the motor 8 and the transmission mechanism 7, the reciprocating sliding assembly 4, the fixed side plate assembly 2 and the cleaning auger assembly 5 perform reciprocating linear motion. During this process, the cleaning auger assembly 5 drives the rotating shaft 51 and the spiral screen plate 52 to rotate through the roller 553 provided therein, thereby turning over the yellow sand and cooling and flame-retardantly treating the magnesium alloy debris scattered into the sand trough 1;

[0060] During the movement of the elastic retractable wheel assembly 55, the state of the rotating shaft 51 is changed by the lifting limit roller 211 and the pressing limit roller 212 provided on the sand trough fixed plate 21, so that the rotating shaft 51 is lifted when moving backward and reset when moving forward, and so on.

[0061] When the rotating shaft 51 is lifted, the flip connecting rod 53 on the rotating shaft 51 works together with the rotating connecting rod and the flip connecting seat 68, pulling the screen 65 to deflect forward along the screen sliding groove 64, so that the screen 65 is matched with the spiral screen plate 52. At this time, the spiral screen plate 52 and the inner wall of the screen 65 are matched to form a semi-enclosed mechanism. During the movement of the entire component toward the tail end of the sand trough fixed plate 21, the roller 553 drives the rotating shaft 51 and the spiral screen plate 52 to rotate, and the magnesium alloy chips in the sand trough 1 are transported along the screen 65 to the chip cleaning streamline 3 in a spiral conveying manner, and then discharged through the chip cleaning streamline 3.

[0062] During this process, the yellow sand is accumulated to one side close to the debris cleaning streamline 3, and during the return stroke of the rotating shaft 51, the rotating shaft 51 is reset, the spiral screen plate 52 is flush with the bottom of the sand trough 1, and the screen 65 is reset and flipped upward. When the roller 553 moves forward, the rotation direction of the rotating shaft 51 is opposite to the original direction. In this way, the originally accumulated yellow sand is spread flat again along the inclined surface of the sand trough 1. This cycle is repeated to achieve real-time processing, cleaning and discharge of the magnesium alloy debris generated in the magnesium alloy die-casting process, thereby achieving the effect of safe production.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements shall fall within the scope of the present invention as claimed.
