Description

Technical Field

[0001] The present application relates to the technical field of metal smelting equipment, and in particular to a furnace slag removal device for metal casting. Background Art

[0002] In the manufacture of industrial products, solid metal blocks, such as aluminum ingots, are usually melted into molten metal. After the molten metal is purified through processes such as slag removal, impurity removal or precipitation, the molten metal is cast into corresponding molds and cast into various products or intermediate products through condensation.

[0003] To melt the metal block into molten metal, it is done under high temperature in a large smelting furnace. After pouring or draining the molten metal, the impurities and sediments at the bottom of the smelting furnace must be cleaned up. The commonly used slag removal method is to place the furnace horizontally and control the mechanical arm with claws at the front end to clamp and transfer. Due to the gap between the claws, the hot impurities are easy to fall during the movement, which increases the danger of the working environment.

[0004] Therefore, it is necessary to provide a slag removal device for a melting furnace used for metal casting to solve the above problems.

[0005] It should be noted that the above information disclosed in this background technology section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute the prior art. Utility Model Content

[0006] Based on the above problems existing in the prior art, the problem to be solved by the present application is: to provide a slag removal device for a melting furnace for metal casting, which solves the problem that hot impurities are easy to fall off during movement.

[0007] The technical solution adopted by the present application to solve the technical problem is: a furnace slag removal device for metal casting, comprising a mechanical arm and a clamping assembly; a base is fixedly installed at the front end of the mechanical arm;

[0008] The clamping assembly comprises a threaded shaft, a support platform, and a clamping part; one end of the threaded shaft passes through the base platform and is connected by a bearing, the end of the threaded shaft away from the base platform is fixedly connected to the support platform, and both ends of the support platform are hinged with a connecting frame; both ends of the support platform are provided with a clamping part, and the ends of the two connecting frames away from the support platform are rotatably connected with the adjacent clamping parts; the clamping part is a rectangular block, and a groove is provided on the side of the clamping part close to the axis of the threaded shaft, and both ends of the groove are connected to the outside;

[0009] Thus, the robot arm controls the movement of the base to realize the movement of the clamping assembly; the clamping assembly enters the furnace, the clamping part is inserted into the impurity pile, and the impurities are collected through the groove.

[0010] Furthermore, the outer wall of the threaded shaft is connected with two threaded sleeves by cooperation; the outer wall of one of the threaded sleeves is provided with a mounting platform, the mounting platform is located on the side of the base close to the support platform, and is fixedly connected to the base; a bidirectional motor is fixedly installed on the inner side of the base away from the mounting platform, and the output end of the bidirectional motor is clamped with the threaded shaft; thus, the threaded sleeve at the mounting platform prevents the mounting platform from rotating with the threaded shaft, and the bidirectional motor can control the threaded shaft to rotate clockwise and counterclockwise.

[0011] Furthermore, the clamping assembly also includes a limit plate, which is a rectangular plate, fixedly mounted at the center of both sides of the support platform and the mounting platform, and the long side of the limit plate is parallel to the axis of the screw shaft; another outer wall of the threaded sleeve is provided with a moving platform, and the moving platform is located between the support platform and the mounting platform, and the side of the moving platform is slidably connected to the limit plate; thereby, the limit plate enhances the stability of the support platform; and at the same time, cooperates with the spiral sleeve at the moving platform to move the moving platform along the axis of the screw shaft.

[0012] Furthermore, both ends of the moving platform are hinged with a connecting frame 2, and the end of the connecting frame 2 away from the moving platform is rotatably connected to an adjustment frame; the inner side of the adjustment frame is pivotally connected to the support platform, and the end of the adjustment frame away from the connecting frame 2 is pivotally connected to the adjacent clamping part; thus, the moving platform approaches the mounting platform, and the adjusting frame is pulled by the connecting frame 2 to rotate a certain angle (with the connection between the adjusting frame and the support platform as the center of the circle), and the adjusting frame pushes the corresponding clamping part to approach the straight line where the axis of the spiral shaft is located; at this time, the clamping part is restricted by the connecting frame 1 and performs stable translation to approach. Then, the impurities between the two clamping parts are squeezed to increase the amount of impurities transferred each time; at the same time, the probability of impurities falling during the transfer process is reduced.

[0013] Furthermore, the support platform is a trapezoidal platform, the adjustment frame is located on a side of the connecting frame 1 close to the lower bottom surface, and the adjustment frame and the connecting frame 1 do not contact each other.

[0014] Furthermore, a support column is installed on one side of the clamping part away from the connecting frame through a clearance fit, one end of the support column is located in the groove, and the other end is located on the outside of the clamping part; a slide plate is fixedly installed on the end of the support column located in the groove, and the slide plate is located in the groove and is slidably connected to the inner wall of the clamping part.

[0015] Furthermore, a fixing frame is fixedly installed on the outer side of the limit plate, and two vertical plates are fixedly installed on the side of the fixing frame away from the mounting platform, and are symmetrically arranged. The vertical plate and the limit plate are not on the same side of the fixing frame, and the two clamping parts are located between the two vertical plates; the side of the vertical plate close to the clamping part is fixedly connected to the adjacent support column; thus, the vertical plate limits the movement of the slide plate through the support column. When the clamping part moves inward to collect impurities, the slide plate gradually moves closer to the bottom of the groove; when the clamping part separates outward, the slide plate gradually moves closer to the opening of the groove. At this time, the slide plate scrapes off the impurities on the inner wall of the groove, cleans the groove to a certain extent, and ensures the subsequent clamping capacity of the clamping part.

[0016] The beneficial effects of the present application are as follows: the present application provides a furnace slag removal device for metal casting, which is provided with a clamping assembly, and a robotic arm controls the movement of a base to realize the movement of the clamping assembly; the clamping assembly enters the furnace, and the clamping part is inserted into the impurity pile to collect the impurities through the groove; because the clamping part forms a semi-enclosed shape, the combination of the two clamping parts can prevent impurities in the groove from falling during movement.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0028] Embodiment 1:

[0029] like Figure 1-Figure 4 As shown, the present application provides a furnace slag removal device for metal casting, comprising a mechanical arm 1 and a gripping assembly 2; a base 11 is fixedly mounted at the front end of the mechanical arm 1;

[0030] Reference Figure 1 , Figure 2 The clamping assembly 2 includes a threaded shaft 21, a support platform 23, and a clamping portion 28; one end of the threaded shaft 21 passes through the base 11 and is connected through a bearing, the end of the threaded shaft 21 away from the base 11 is fixedly connected to the support platform 23, and both ends of the support platform 23 are hinged with a connecting frame 231; both ends of the support platform 23 are provided with a clamping portion 28, and the ends of the two connecting frames 231 away from the support platform 23 are rotatably connected to the adjacent clamping portion 28; the clamping portion 28 is a rectangular block, and a groove 281 is provided on the side of the clamping portion 28 close to the axis of the threaded shaft 21, and both ends of the groove 281 are connected to the outside;

[0031] Thus, the robot arm 1 controls the movement of the base 11 to realize the movement of the clamping assembly 2; the clamping assembly 2 enters the furnace, the clamping part 28 is inserted into the impurity pile, and the impurities are collected through the groove 281.

[0032] Among them: Reference Figure 1 , Figure 2 , Figure 3The outer wall of the threaded shaft 21 is connected with two threaded sleeves 22 by cooperation; the outer wall of one of the threaded sleeves 22 is provided with a mounting platform 24, and the mounting platform 24 is located on the side of the base 11 close to the support platform 23, and is fixedly connected to the base 11; a bidirectional motor 12 is fixedly installed on the inner side of the base 11 away from the mounting platform 24, and the output end of the bidirectional motor 12 is clamped with the threaded shaft 21; thus, the threaded sleeve 22 at the mounting platform 24 prevents the mounting platform 24 from rotating with the threaded shaft 21, and the bidirectional motor 12 can control the threaded shaft 21 to rotate clockwise and counterclockwise.

[0033] Reference Figure 3 , Figure 4 The clamping assembly 2 also includes a limit plate 26, which is a rectangular plate. The limit plate 26 is fixedly installed at the center of both sides of the support platform 23 and the mounting platform 24, and the long side of the limit plate 26 is parallel to the axis of the screw shaft 21; the outer wall of the other threaded sleeve 22 is provided with a moving platform 25, and the moving platform 25 is located between the support platform 23 and the mounting platform 24, and the side of the moving platform 25 is slidably connected to the limit plate 26; thereby, the limit plate 26 enhances the stability of the support platform 23; at the same time, it cooperates with the spiral sleeve 22 at the moving platform 25 to make the moving platform 25 move along the axis of the screw shaft 21.

[0034] Reference Figure 2 , Figure 4 , both ends of the moving platform 25 are hinged with a connecting frame 251, and the end of the connecting frame 251 away from the moving platform 25 is rotatably connected with an adjusting frame 27; the inner side of the adjusting frame 27 is pivoted with the supporting platform 23, and the end of the adjusting frame 27 away from the connecting frame 251 is pivoted with the adjacent clamping part 28; thus, the moving platform 25 approaches the mounting platform 24, and the adjusting frame 27 is pulled to rotate a certain angle (with the connection between the adjusting frame 27 and the supporting platform 23 as the center of the circle) by the connecting frame 251, and the adjusting frame 27 pushes the corresponding clamping part 28 to approach the straight line where the axis of the spiral shaft 21 is located; at this time, the clamping part 28 is restricted by the connecting frame 1 231, and moves closer in a stable translation. Thus, the amount of impurities transferred each time is increased; at the same time, the impurities between the two clamping parts 28 are squeezed, and the probability of impurities falling during the transfer process is reduced.

[0035] Reference Figure 3 , Figure 4 The support platform 23 is a trapezoidal platform, and the adjustment frame 27 is located on a side of the connecting frame 231 close to the lower bottom surface, and the adjustment frame 27 and the connecting frame 231 do not contact each other.

[0036] Its working process is:

[0037] The robot arm 1 controls the movement of the base 11 to insert the horizontal clamping assembly 2 into the impurity pile; the bidirectional motor 12 can control the rotation of the threaded shaft 21, the moving platform 25 moves toward the mounting platform 24, the connecting frame 251 pulls the adjustment frame 27 to rotate a certain angle with the connection between the adjustment frame 27 and the support platform 23 as the center, and the adjustment frame 27 pushes the corresponding clamping part 28 to approach the straight line where the axis of the screw shaft 21 is located; at this time, the clamping part 28 is restricted by the connecting frame 1 231 and moves closer to each other in a stable translation. As a result, the two clamping parts are close to each other, and the two grooves 281 are combined to increase the number of impurities transferred each time; at the same time, the impurities between the two clamping parts 28 are squeezed, and the tightness between the impurities in the groove 281 is increased, thereby reducing the probability of impurities falling during the transfer process.

[0038] Then the robot arm 1 controls the movement of the base 11 to move the clamping component 2 from the furnace to the recovery position, and the mechanical wall 1 adjusts the angle of the base 11 to tilt the clamping component 2 at a certain angle; the bidirectional motor 12 controls the threaded shaft 21 to rotate in the opposite direction, and the moving platform 25 moves toward the supporting platform 23. The connecting frame 251 pulls the adjusting frame 27 to rotate a certain angle with the connection between the adjusting frame 27 and the supporting platform 23 as the center, and the adjusting frame 27 pulls the corresponding clamping part 28 away from the straight line where the axis of the screw shaft 21 is located, thereby releasing impurities.

[0039] Example 2: Reference Figure 5 , based on the first embodiment, further optimization is proposed, the specific contents are as follows:

[0040] A support column 291 is installed on one side of the clamping portion 28 away from the connecting frame 231 through a clearance fit, one end of the support column 291 is located in the groove 281, and the other end is located on the outside of the clamping portion 28; a slide plate 292 is fixedly installed on one end of the support column 291 located in the groove 281, and the slide plate 292 is located in the groove 281 and is slidably connected to the inner wall of the clamping portion 28.

[0041] A fixing frame 293 is fixedly installed on the outer side of the limiting plate 26, and two vertical plates 294 are fixedly installed on the side of the fixing frame 293 away from the mounting platform 24, and are symmetrically arranged. The vertical plates 294 and the limiting plate 26 are not on the same side of the fixing frame 293, and the two clamping parts 28 are both located between the two vertical plates 29; the side of the vertical plate 294 close to the clamping part 28 is fixedly connected to the adjacent support column 291.

[0042] The working process is as follows: when the clamping part 28 moves inward to collect impurities, the slide plate 282 gradually moves closer to the bottom of the groove 281, and the vertical plate 294 limits the movement of the slide plate 282 through the support column 291, and the impurities between the slide plate 282 and the inside of the clamping part 28 are squeezed; when the clamping part 281 separates outward, the slide plate 282 gradually moves closer to the opening of the groove 281. At this time, the slide plate 282 scrapes off the impurities on the inner wall of the groove 281, and cleans the groove 281 to a certain extent, thereby ensuring the capacity of the clamping part for subsequent clamping.

[0043] In the above-mentioned first and second embodiments, a blade is provided at one end of the clamping portion 28 away from the support platform 23, so as to scrape and clean the inner wall of the furnace.

[0044] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
