Abstract
The utility model discloses a new pressing device used for a crucible. The utility model has a structure of that a pressing-rod (1) is connected with an lifting plate (6) through a pin (2), a gasket (3) and a split pin (4); the lifting plate (6) is connected with the outer-wall of an uplifting bag; a nut (7) is arranged on the lifting plate (6) and a thread taper shaft (5) is connected with the pressing-rod (1) through the nut (7). Four to eight pressing devices can be arranged around the uplifting bag according to the size of the uplifting-bag and crucible.
Description
Technical field:
The utility model relates to a kind of crucible hold down gag.
Background technology:
Smelt in the production at the magnesium titanium, crucible is used for splendid attire melt magnesium metal, about 720 ℃ of temperature.Crucible put into two-man ladle, tumble and two-man ladle, the melt magnesium metal in the crucible is poured out, ingot casting becomes piece.
The purposes of crucible hold down gag is to put into when two-maing ladle when crucible crucible is compressed with two-maing ladle, and crucible does not take place with respect to the slip of two-maing ladle when two-maing ladle tumbling.But crucible hold down gag in the past is that the mode with urgent voussoir compresses depression bar, but replaces with a voussoir.This kind structure voussoir gets loose easily, does not press tightly crucible and produce, accident and potential safety hazard that crucible slides.
Summary of the invention:
The purpose of this utility model is: a kind of crucible hold down gag is provided, guarantees that crucible does not take place with respect to the slip of two-maing ladle when two-maing ladle tumbling.
The utility model is to constitute like this: it comprises depression bar (1), and depression bar (1) is connected with otic placode (6), and otic placode (6) is connected with the outer wall of two-maing ladle; Nut (7) is arranged on otic placode (6), and the screw thread axis of cone (5) is connected with depression bar (1) by nut (7).
Depression bar (1) is connected with otic placode (6) by bearing pin (2), pad (3), split pin (4).
Operation principle: when crucible put into two-man ladle after, rotate depression bar (1), make depression bar (1) press to crucible, then insert the threaded axis of cone (5), along with screw thread moving in nut (7), the screw thread axis of cone (5) moves forward, and the conical surface is pressed to the arc surface on the depression bar (1), makes depression bar (1) compress crucible gradually.Because of nut (7) is welded on the otic placode (6), so the screw thread axis of cone (5) can not deviate from.
Handle in the rotation screw thread axis of cone (5), when the conical surface was pressed to arc surface on the depression bar (1), the turning moment on the handle produced the power that makes the screw thread axis of cone (5) thrust forward and press to depression bar (1).The tapering of this axis of cone is 1: 4, therefore, when turning moment produces 1KN thrust, produces the power that 4KN is pressed to crucible simultaneously.Thereby this structure is laborsaving.Because of screw thread does not bear the counter-force that depression bar produces, thereby the screw thread reliable operation, this structural safety is reliable.
According to two-maing ladle and the size of crucible, 4 to 8 this kind hold down gags can distribute on the circumference of two-maing ladle.
The beneficial effects of the utility model are: simple in structure, and work laborsaving, reliable, safety.
Description of drawings:
Fig. 1: structural representation of the present utility model;
Fig. 2: the A of structural representation of the present utility model is to view;
Fig. 3: application schematic diagram of the present utility model.
The specific embodiment:
Embodiment of the present utility model:, assemble according to shown in the accompanying drawing according to two-maing ladle and the size design of crucible and make each part.At first otic placode 6 is welded on the outer wall of two-maing ladle, nut 7 is welded on the otic placode 6, secondly with bearing pin 2, pad 3, split pin 4 depression bar 1 and otic placode 6 are connected and fixed, crucible are put into two-mand ladle then, rotate depression bar 1, make depression bar 1 press to crucible, insert the screw thread axis of cone 5 at last, the screw thread of its front end cooperates with nut 7, and its rear end cylindrical section cooperates with circular hole on the otic placode 6, the conical surface is pressed to the arc surface on the depression bar 1, makes depression bar 1 compress crucible gradually.
