Description

Technical Field

[0001] The present invention relates to the technical field of aluminum casting, and particularly relates to a die leveling device for aluminum casting processing. Background Art

[0002] Aluminum casting is one of the aluminum processing methods. Among them, the casting processing of plate-shaped aluminum materials (aluminum plates) is the most common processing type in aluminum casting processing. The melting and casting of aluminum plates require melting aluminum billets first. The melted aluminum liquid is transported to the forming die through a guiding groove. There is leveled sand piled up in the forming die. When the aluminum liquid is transported to the die, by spreading the aluminum liquid flat to cover the die, the aluminum liquid will quickly cool and solidify, and then form an aluminum plate profile under the limitation of the die.

[0003] In the above processing method, the leveling of the sand in the die is related to the production quality of the aluminum plate. In the prior art, when leveling the sand in the die, the die needs to be placed on a vibrating device first, and then the sand is filled into the die. The vibrating device vibrates the die, so that the sand in the die is flattened and compacted in the die to form a preliminary flattening operation. Subsequently, secondary leveling is carried out through the cooperation of a leveling device and manual work. In actual production activities, the size specifications of aluminum plates are often different, so the corresponding die sizes are also different. However, the existing leveling devices can often only level the aluminum plate dies of the same size. When facing dies of different sizes, different models of leveling devices need to be replaced, so they cannot meet more usage requirements, and the flexibility of use is relatively low.

Detailed implementation manners

[0024] To make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention will be given in conjunction with the accompanying drawings of the specification.

[0025] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0026] Embodiment Referring to Figures 1 to 7 , which is an embodiment of the present invention, including a die leveling device for aluminum casting processing, including a base 1. A leveling unit 2 is horizontally arranged above the base 1. A support unit 3 is arranged in parallel above the leveling unit 2. A rolling unit 4 is arranged in parallel on the side of the leveling unit 2. A flattening unit 5 is arranged on the other side of the leveling unit 2. The whole device is located outside a vibration device 6, and a mold 7 for casting aluminum plates is located on the vibration device 6. After the vibration device 6 initially levels and compacts the sand on the mold 7, the leveling device then performs a secondary leveling operation on it; The leveling unit 2 includes a connecting component 21 horizontally arranged on the base 1, two groups of extending components 22 symmetrically and slidably inserted at both ends of the connecting component 21, and a connecting assembly 23 respectively connected to the outer ends of the two groups of extending components 22. The bottoms of the connecting component 21 and the extending components 22 are at the same horizontal height. Therefore, when the extending components 22 slide telescopically at both ends of the connecting component 21, their bottoms still remain at the same horizontal height. Furthermore, it is ensured that after the leveling unit 2 adjusts the leveling range, it can still push the surface of the sand pile located below it to the same horizontal height, achieving the purpose of leveling sand in different ranges; The connecting component 21 includes a screed plate one 211 with a wedge-shaped structure, and a storage rack one 212 fixedly connected to the side of the screed plate one 211. The storage rack one 212 is in a C-shaped structure with an upward opening. When the wedge-shaped screed plate one 211 contacts the sand pile, it can first push the sand forward. The moving sand will, under the action of the thrust, preferentially move to both sides, thereby filling the sunken areas on the sides. When the sunken areas are filled, the excess sand will move upward along its top inclined plane into the storage rack one 212 under the action of the thrust, and then be collected by the storage rack one 212 to prevent too much sand from affecting the subsequent leveling work; The extending component 22 includes a screed plate two 221 stored inside the screed plate one 211, and a storage rack two 222 arranged on the side of the screed plate two 221 and located inside the storage rack one 212. The storage rack two 222 is also in a C-shaped structure with an upward opening. The structure of the screed plate two 221 is the same as that of the screed plate one 211, and the structure of the storage rack two 222 is the same as that of the storage rack one 212. Therefore, the overall function and the achieved effect of the extending component 22 are the same as those of the connecting component 21. The additional difference of the extending component 22 is that it can be stored inside the connecting component 21, thereby achieving the purpose of adjusting the overall length of the leveling unit 2, and thus realizing the purpose of adjusting the leveling range of the leveling unit 2.

[0027] Furthermore, referring to Figure 3 , the connecting component 21 further includes a chute one 213 opened inside the storage rack one 212, a storage groove 214 opened inside the screed plate one 211 and matching the screed plate two 221, and a cross plate 215 horizontally fixedly connected to both ends of the chute one 213. The chute one 213 is used to limit and fix the extending component 22, and the storage groove 214 is used to provide a space for storing the screed plate two 221.

[0028] Furthermore, referring to Figure 3 , the extending component 22 further includes a chute two 223 opened on the bottom surface of the storage rack one 212, and the chute one 213 is vertically connected to the chute two 223, and a limiting slider 224 arranged at one end of the chute two 223 and slidably connected to the chute one 213 in a matching manner. The storage rack two 222 is used to provide a space for storing the storage rack one 212, so that the extending component 22 can be closely contracted at one end of the connecting component 21. The limiting slider 224 cooperates with the cross plate 215 and the chute one 213, and can ensure that while the extending component 22 slides on the side of the connecting component 21, it does not completely separate from the connecting component 21. The way of connecting the chute one 213 and the chute two 223 can make the sand in the storage rack one 212 and the storage rack two 222 fall downward along the chute one 213 and the chute two 223, thereby realizing the function of filling the depression.

[0029] Among them, referring to Figure 2, the base 1 is integrally U-shaped. The base 1 includes two sets of symmetrically arranged track frames 11, an adjusting rod 12 horizontally arranged within the two sets of track frames 11, support screws 13 symmetrically threadedly inserted at both ends of the adjusting rod 12, and the outer ends of the support screws 13 are fixedly connected to the track frames 11, as well as a sliding frame 14 vertically arranged on the track frames 11, and the sliding frame 14 can slide horizontally along the track frames 11. The top end of the sliding frame 14 is fixedly connected to the outside of the connecting assembly 23. The U-shaped base 1 enables the entire leveling device to be moved and installed from the side of the mold 7 to the working area. The two sets of support screws 13 symmetrically threadedly connected to both ends of the adjusting rod 12 enable the adjusting rod 12 to drive the support screws 13 at both ends when rotating, driving the two sets of track frames 11 to move in opposite directions. The track frames 11 moving in opposite directions drive the leveling unit 2, the support unit 3, the rolling unit 4, and the spreading unit 5 connected to the connecting assembly 23 to adjust the length range through the fixed connection between the sliding frame 14 and the connecting assembly 23, thereby achieving the purpose of adjusting the overall leveling range of the leveling device and realizing the function of leveling the sand on the support unit 3 of different sizes. The bottom of the sliding frame 14 is an electric slide table, which can slide horizontally along the track frames 11, thereby driving the leveling device to perform leveling work. The upper part is a triangular support frame, which has strong support stability.

[0030] Among them, referring to Figure 2 , the support unit 3 includes a support frame 31 horizontally arranged above the leveling unit 2, and telescopic rods 32 symmetrically arranged on both sides above the support frame 31. The outer ends of the telescopic rods 32 are fixedly connected to the connecting assembly 23. The telescopic rods 32 can adaptively expand and contract following the adjustment of the base 1. The support unit 3 installed above the leveling unit 2 is generally used to provide horizontal support for the leveling device from above.

[0031] Among them, referring to Figure 4The rolling unit 4 includes a connecting plate 41 fixedly connected to the connecting component 23, two groups of pressure components 42 symmetrically arranged on both sides of the connecting plate 41, a limiting shaft 43 connected to one group of pressure components 42, and a rolling shaft 44 connected to the other group of pressure components 42. Two groups of pressure components 42 are installed at both ends of the rolling unit 4. On the two symmetrical groups of pressure components 42, one group is installed with the limiting shaft 43, and the other group is installed with the rolling shaft 44, and the limiting shaft 43 extends into the rolling shaft 44 opposite to it. Therefore, the four Two groups of limit shafts 43 and roller shafts 44 are installed alternately between the pressure components 42. When the two sides of the roller unit 4 move following the smoothing unit 2, the limit shafts 43 and roller shafts 44 inserted into each other will extend in relative directions, thereby adapting to the changes when the length of the roller unit 4 is adjusted. At this time, the two groups of roller shafts 44 will form a staggered position state. The two groups of staggered roller shafts 44 have a part that overlaps in the horizontal direction. Therefore, the two groups of roller shafts 44 can form a group of continuous rolling ranges, thereby avoiding the generation of rolling dead angles.

[0032] Among them, refer to Figure 4 The pressure assembly 42 includes a sleeve 421 fixedly connected to the connecting plate 41, an adjustment groove 422 opened on the outer wall of the sleeve 421, a push rod 423 inserted into the sleeve 421, and the end of the push rod 423 extends to the outside of the sleeve 421, and a ring 424 fixedly connected to the end of the push rod 423.

[0033] Further, see Figure 5 The adjustment groove 422 is composed of a vertical groove opened in the vertical direction and three groups of vertically offset parallel transverse grooves, and the ends of the three groups of transverse grooves are connected to the vertical grooves, and can slide into the three groups of transverse grooves along the vertical grooves, and the three groups of transverse grooves are at different horizontal heights.

[0034] Further, see Figure 5 , a spring 426 is arranged in the sleeve 421, and the outer end of the spring 426 extends to the outside through the adjusting groove 422, a spring 426 is arranged between the push rod 423 and the paddle 425, and the spring 426 is located in the sleeve 421 as a whole, and the spring 426 pushes the push rod 423 downward all the time through elastic support, thereby assisting the roller pressure shaft 44 to apply rolling pressure, and by adjusting the position of the paddle 425 in the adjusting groove 422 and placing the paddle 425 in the horizontal grooves of different heights in the adjusting groove 422, the distance between the push rod 423 and the paddle 425 will be shortened, thereby compressing the length and activity space of the spring 426, and since the elastic length of the spring 426 changes, its elastic supporting force will also change accordingly, thereby strengthening the elastic supporting force of the spring 426, thereby realizing the function of adjusting the spring 426 to assist the roller pressure shaft 44 in applying rolling pressure, thereby meeting more usage requirements.

[0035] Among them, refer to Figure 6, the flattening unit 5 includes a first flattening frame 51 and a second flattening frame 52 fixedly connected to two sets of connecting components 23 respectively. The first flattening frame 51 and the second flattening frame 52 are arranged in a staggered manner. The inner side of the first flattening frame 51 is attached to the outer side of the second flattening frame 52. The first flattening frame 51 and the second flattening frame 52 have the same structure, both of which are rake structures. They can initially flatten the sand and the sand pile, preventing uneven distribution of the sand when the sand is later leveled and roll-pressed. The rake tooth structure can reduce the resistance of the flattening unit 5 during the initial flattening of the sand. Moreover, the first flattening frame 51 and the second flattening frame 52 can move along with the corresponding connecting components 23. The staggered setting ensures that there is no omission in the flattening area during range adjustment, guaranteeing the effect of the leveling work.

[0036] In summary, referring to Figure 7 , when using the equipment for the leveling work of the mold 7, according to the application size range of the mold 7, rotate the adjusting rod 12. The adjusting rod 12 drives the two sets of track frames 11 pushed by the support screw rod 13 through the thread to move in opposite directions. The track frames 11 moving in opposite directions are fixedly connected to the connecting components 23 through the sliding frames 14, and the two sets of extension components 22 move towards both sides of the connecting component 21 respectively, achieving the function of adjusting the grinding range of the leveling unit 2; At the same time, the connecting component 23 also drives the pressure component 42 to drive the two sets of limit shafts 43 and the two sets of roller pressing shafts 44 to move in opposite directions for adjustment, achieving the purpose of adjusting the rolling range of the rolling unit 4; And the first flattening frame 51 and the second flattening frame 52 located on the other side of the connecting component 23 also make corresponding position adjustments, realizing the purpose of adjusting the flattening range of the flattening unit 5; Through the above operations, the purpose of adjusting the leveling range of the leveling equipment according to the actual size of the mold 7 can be achieved, realizing the function of leveling different-sized molds 7, thereby meeting more usage requirements and improving the usage flexibility of the device; Referring to Figure 4, after the leveling range is adjusted, the sliding frame 14 drives the leveling unit 2, the rolling unit 4, and the spreading unit 5 to slide horizontally on the mold 7 synchronously. During the sliding process, the spreading unit 5 first contacts the sand, and through its rake-like structure, it will initially level the uneven sand piled up in the mold 7 to prevent uneven sand distribution during the subsequent leveling and rolling of the sand; then the moving leveling unit 2 contacts the sand and will level the spread sand. The leveling plate one 211 and the leveling plate two 221 of the wedge-shaped structure contact the sand, first push the sand forward, and the moving sand will, under the action of the thrust, fill the sunken area. When the sunken area is filled, the excess sand will move upward along the top inclined surfaces of the leveling plate one 211 and the leveling plate two 221 into the storage rack one 212 and the storage rack two 222, and then be collected by the storage rack one 212 to prevent excessive sand from affecting the subsequent leveling work. For the sand in the storage rack two 222 and the storage rack one 212, during the leveling process of the leveling unit 2, if it encounters a sunken area, the sand inside will fall downward through the chute one 213 and the chute two 223 into the pit 8 to fill the pit 8, further ensuring the effect of the leveling work; finally, the rolling unit 4 contacts the sand that has been leveled by the spreading unit 5 and the leveling unit 2 successively. The rolling shaft 44 will further roll the leveled sand through the elastic pressure of the pressure component 42 to reduce the gaps between the sands, further ensuring the effect of the leveling work. Through the above series of operations, the sand in the mold 7 can be leveled, so that the upper surface of the sand is at the same horizontal height, meeting the requirements of the aluminum plate casting work.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
