Abstract
The invention aims to provide a hold-down mechanism of a fixed mould of a gird continuous casting machine of a lead-acid storage battery for adjusting distance between a movable mould and the fixed mould of the grid continuous casting machine. The hold-down mechanism comprises a screw rod and a screw rod sleeve which is located in a guide sleeve; the screw rod is threaded with the screw rod sleeve, and then supported in a bearing sleeve by a bearing; an internal cylinder capable of holding a pressure sensor and a spring is arranged at one end of the screw rod sleeve which is not matched with the screw rod; one end of the spring is connected with the pressure sensor while the other end thereof is connected with an ejector pin. The hold-down mechanism can both avoid overflow of liquid lead out of the cavity because of too large match gap of the moulds and prevent power loss of the continuous casting machine and abrasion of the surface of the mould because of increased friction force between the fixed mould and the movable mould due to too small match gap of the moulds during a work progress.
Description
Technical field
The present invention relates to the equipment of continuous casting of metal, particularly a kind of hold-down mechanism of stereotype grid conticaster cover half.
Background technology
Cooperation between the battery grid conticaster mould is very important for the forming process of battery grid.Publication number is that the Chinese patent of CN101670422A discloses a kind of stereotype conticaster.This invention is adopted two and is fixed on roll pressed stereotype moulding on the brace table, that have the gap.Because in process of production, roll expands with heat and contract with cold, and has caused described gap to change, and influences the thickness of institute's cast article.
Summary of the invention
The hold-down mechanism that the purpose of this invention is to provide a kind of lead acid accumulator plate grid conticaster cover half.The conticaster that this hold-down mechanism was suitable for has rotating dynamic model and cover half with matching.The rotating shaft of described dynamic model is fixed on the frame, and the distance between described cover half and the dynamic model can be regulated by mechanism provided by the present invention.
For realizing that the technical scheme that the object of the invention adopts is such, a kind of hold-down mechanism of lead acid accumulator plate grid conticaster cover half is characterized in that: comprise screw rod, and the screw rod cover that is positioned at fairlead inside;
Described screw rod and described screw rod cover are supported in the bearing holder (housing, cover) by bearing by after the threaded engagement again;
Described screw rod overlaps an end that does not cooperate with described screw rod, has the inner core of hold pressure unit and spring;
One end of described spring connects pressure sensor, and the other end connects push rod.
The present invention is owing to have said structure, and its advantage is: both can prevent the excesssive gap that mould cooperates, plumbous hydrorrhea goes out dynamic model surface type chamber in casting process, and the grid of filling between the grid causes product rejection; Prevented again that fit clearance is too small, the frictional force between cover half and the dynamic model strengthens, and makes conticaster power loss, die surface wearing and tearing.
Further, the screw rod among the present invention is not connected handwheel with the end that described screw rod cover matches.So that install and regulate.
Description of drawings
Device of the present invention can further specify by the non-limiting embodiment that accompanying drawing provides.
Fig. 1 is a stereogram of the present invention;
Fig. 2 is a cutaway view of the present invention;
Fig. 3 is an installation diagram of the present invention.
Among the figure: 1-1, hold-down mechanism, 1-2, cover half, 1-3, dynamic model, 2, handwheel, 3, screw rod, 4, bearing holder (housing, cover), 5, fairlead, 6, the screw rod cover, 7, sensor, 8, spring, 9, push rod, 10, frame.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples:
Referring to accompanying drawing: the hold-down mechanism 1-1 of the lead acid accumulator plate grid conticaster cover half among the figure, comprise screw rod 3, and the screw rod cover 6 that is positioned at fairlead 5 inside;
Described screw rod 3 is supported in the bearing holder (housing, cover) 4 by bearing 4-1 after passing through threaded engagement with described screw rod cover 6 again;
Described screw rod overlaps 6 ends that do not cooperate with described screw rod 3, but has the inner core of hold pressure unit 7 and spring 8;
One end of described spring 8 connects pressure sensor 7, and the other end connects push rod 9.
In an embodiment, screw rod 3 is not connected handwheel 2 with described screw rod cover 6 ends that match.Come hold-down mechanism is regulated so that rotate described screw rod 3.
The present invention the hold-down mechanism 1-1 that provided be fixed on the frame 10 of conticaster.On the described continuous casting, rotating dynamic model 1-3 is installed on the described frame 10 by rotating shaft, and cooperates with cover half 1-2.By rotating screw bolt 3, make the push rod 9 of hold-down mechanism 1-1 contact, and then adjust the distance between described cover half 1-2 and the dynamic model 1-3 with cover half 1-2.
Because push rod 9 elasticity are connected in hold-down mechanism 1-1, when described mould causes owing to expanded by heating in process of production that the die clearance reduces, when active force between the mould increases, spring 8 corresponding contractions, keep the die clearance within reasonable range, avoid because too small aggravation die wear in die clearance or mould are stuck.The pressure sensor 7 of spring 8 one ends is used to detect the active force between cover half 1-2 and the dynamic model 1-3, so that regulate.
