Description

Technical Field

[0001] The utility model belongs to the technical field of transfer and distribution equipment, and particularly relates to an intelligent sand box distributor. Background Art

[0002] In V-method casting, after the sand in the flask undergoes a series of processes, including compaction and vacuuming, a pattern is formed, ready for pouring. The flask is placed on a pouring roller and slowly moved to the pouring station for pouring. In V-method casting, vacuuming is required continuously from the moment the sand is compacted into the pattern until the sand is shaken out after pouring. This process requires vacuuming whether the flask is moving or stationary.

[0003] Some foundries have a high degree of automation and many flasks. All casting takes place on the pouring roller. Therefore, the casting roller needs to move forward with the vacuum system. Currently, a common method is to have an independent vacuum tube on each flask to move along with it. However, this also requires many vacuum tubes to move together, making the scene rather messy. A more advanced method is to use a mobile vacuum beam in conjunction with a fixed vacuum beam, so that the flasks can be moved forward in sequence on the pouring roller, one station at a time. This method is more organized than the previous method of having each flask equipped with a vacuum tube, but it also has limitations: each flask must move forward in sequence. Utility Model Content

[0039] The flask line 1 comprises two ground guide rails 101, between which flasks 102 are placed at equal distances;

[0040] The guide rail bracket 2 includes columns 201 equidistantly installed on the rear side of the ground guide rail 101, and upper guide rails 202 are installed on the upper side of all the columns 201;

The upper running mechanism 302 and the lower running mechanism 304 operate synchronously;

[0042] The grabbing mechanism 4 includes a telescopic cylinder 401 installed on the upper side of the mounting plate 301, the output end of the telescopic cylinder 401 passes through the mounting plate 301, the output end of the telescopic cylinder 401 is connected to a rectangular plate 402, a limiting column 403 is installed on the upper side of the rectangular plate 402, the limiting column 403 is installed with a rack 404, the mounting plate 301 is installed with a limiting gear 405 meshing with the rack 404, two groups of grabbing box cylinders 406 are symmetrically installed on both sides of the rectangular plate 402, the two groups of grabbing box cylinders 406 are hingedly installed on the rectangular plate 402, and the output ends of the two grabbing box cylinders 406 on one side are hingedly installed with a hinge block 407, the hinge block 407 is fixedly installed with a connecting plate 408, and claws 409 are fixedly installed at both ends of the connecting plate 408, and the ends of the claws 409 are hingedly installed on the rectangular plate 402, and the claws 409 are U-shaped.

Because it is a semi-gantry car body 3, the back side of the sand box is not blocked, and pouring can be carried out on the back side of the sand box. After the sand box pressure maintenance is completed, when the sand box needs to be taken out, the upper walking mechanism 302 and the lower walking mechanism 304 operate synchronously, driving the semi-gantry car body 3 to move to the sand box position where the pressure maintenance is completed under the limit of the ground guide rail 101 and the upper guide rail 202.

During the period of this vacuuming, the driving motor 410 rotates, driving the clamped sand box to rise, and then the semi-gantry body 3 moves to move the sand box to the unloading position. The driving motor 410 and the box grabbing cylinder 406 run, and the purpose of placing the sand box to the unloading position is achieved.

[0046] Preferably, sleepers are laid on the lower side of the ground guide rail 101.

With this design, when the sand box needs to be poured, the pouring machine or ladle can pour directly from this surface, which is convenient for pouring. In fact, the height size that is conducive to pouring can also be considered according to specific circumstances.

[0050] Preferably, there are four telescopic cylinders 401, which are placed at the four corners of the rectangular plate 402. This design plays a guiding role and also ensures that the rectangular plate 402 is lifted and lowered horizontally. In fact, the number and installation position of the telescopic cylinders 401 can also be considered according to specific circumstances.

[0051] Preferably, the end portion where the clamping jaw 409 contacts the rectangular plate 402 is threadedly connected with an interference screw 411.
