Gravity extrusion type lead belt casting machine

Abstract

The invention discloses a gravity extrusion type lead belt casting machine which is provided with a casting hopper for storing liquid lead. The lower portion of the casting hopper is communicated with a casting channel in the vertical direction, the outlet end of the casting channel is connected with a lead belt molding channel in the horizontal direction, a cooling device is wrapped by the molding channel, the liquid lead flowing through the molding channel is cooled to form a solid lead belt, a drawing device for drawing the solid lead belt out is arranged at the outlet end of the molding channel, and a liquid lead heating device and a liquid lead temperature sensor are arranged at the outlet end of the casing channel. The casting machine can produce lead belts of different dimensions and is high in production flexibility, the molding channel is provided with a hollow interlayer, a supporting partition plate is arranged in the interlayer, roller shape of the molding channel can be kept effectively, the molding channel adopts the cooling device with a closed inner portion, and quality of cooling liquid can be effectively guaranteed.

Description

technical field [0001] The invention relates to a gravity extrusion type lead strip casting machine, in particular to a device which utilizes the self-weight of lead liquid to drive the lead strip to form by extrusion. Background technique [0002] At present, the main technologies used in the forming equipment for producing lead strips on the market are as follows: the casting mold adopts rollers with grooves on the outer circle, the grooves are wrapped by steel strips, and the steel strips are always in a state of circular motion. The melted lead liquid is cast in the groove, and the casting mold is cooled at the same time. The cooling system includes an inner spray device and an outer spray device, which sprays and cools the coated lead liquid, so that the lead belt can be cooled during this process. After medium solidification and solidification, it is taken out by the guiding mechanism for subsequent processing. Wherein, the outer spraying device directly sprays the wr...

Problems solved by technology

[0003] If the lead strip with a width of more than 200mm is produced, the steel strip will always be in a tempering state due to the short circulation stroke of the steel strip and the direct spraying of the inner and outer layers. After a long time, the steel strip will be thermally deformed and unable to Maintaining a flat state will affect the forming lead belt. In severe cases, continuous casting will not be possible. The steel belt needs to be replaced after a short period of time, such as within a week, which seriously affects the normal use of the equipment and increases equipment maintenance. costs, reducing manufacturing efficiency

[0004] The width of the lead strip formed by this type of equipment is determined by the groove width of the forming roller, so once the fixed roller is installed, only one specification of lead strip can be produced, and different rollers must be replaced when producing rough lead strips of different specifications , the production flexibility is greatly reduced

[0005] In addition, the external spray coolant cannot be effectively controlled and recovered. Due to direct contact with the outside world, the coolant is easily polluted, and dust, oil and other debris will fall into the coolant, which reduces the quality of the coolant. shower effect

[0006] In order to meet the market demand, it is now necessary to develop a thick lead strip with a width of 400mm and a thickness of 12mm. Therefore, the existing technology has been unable to meet this need
