Description

Technical Field

[0001] The utility model relates to the technical field of nozzle production, in particular to a stretching device for nozzle iron shell production. Background Art

[0002] The nozzle is the junction between the frame and the component, formed during the casting process. Also known as the "soup mouth," it serves as the inlet and outlet for the flow of heated liquid material. Submerged nozzles are widely used in foundries. Their primary function is to prevent secondary oxidation and splashing of molten steel during the casting process, and to prevent mold slag from entering the molten steel.

[0003] When producing the nozzle, it is necessary to stretch the sheet patch of the iron shell in production. During the stretching process, the iron sheet may produce wrinkles, resulting in a significant reduction in the quality of the iron sheet production, which cannot meet the use needs of the staff.

DETAILED DESCRIPTION

[0019] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0020] like Figure 1-Figure 3 As shown, the embodiment of the present invention provides a stretching device for producing a nozzle iron shell, comprising:

[0021] The base 1 has a set of table legs 18 fixedly mounted on the lower end surface of the base 1, and anti-slip grooves are installed on the lower end surfaces of the set of table legs 18, so that the staff can stably place the device in the designated position to work. A positioning assembly is installed on the base 1, and the positioning assembly includes an extension block 12 fixedly mounted on the upper end surface of the base 1, and a limiting block 13 is slidably connected inside the extension block 12. The limiting block 13 can fix one end of the iron sheet so that it will not move. Both ends of the limiting block 13 are slidably penetrated by a slide rod 20, and one end of the two slide rods 20 is fixedly connected to the lower end surface of the extension block 12, and the other end of the two slide rods 20 is fixedly connected to the upper end surface of the base 1. The slide rod 20 can limit the limiting block 13 so that the limiting block 13 does not shake when it descends. A screw rod 14 is rotatably connected to the upper end surface of the limiting block 13, and the other end of the screw rod 14 is threaded through the extension block 12, and a knob 19 is installed at one end of the screw rod 14;

[0022] The staff can easily rotate the screw 14 by rotating the knob 19, thereby completing the lifting and lowering of the limit block 13. A placement opening 15 is opened on the base 1, and a platform 16 is slidably connected in the placement opening 15. A telescopic motor 17 is fixedly installed on the lower end surface of the base 1. The telescopic motor 17 is a prior art that can make the object connected to its motor shaft move back and forth. The motor shaft of the telescopic motor 17 rotates through the base 1 and is fixedly connected to one end of the platform 16. Through the above structure, one end of the iron sheet can be stably clamped by the limit block 13, and the iron sheet can be pushed upward by the platform 16 so that it can be close to the extrusion roller 8, the stretching assembly, the stretching assembly includes a slide groove 2 opened on the base 1, a slider 3 is slidably connected in the slide groove 2, one end of the slider 3 is threaded through a threaded rod 4, and both ends of the threaded rod 4 are rotatably connected in the slide groove 2, a sliding groove 5 is opened on the side wall of the base 1, and a sliding block 6 is slidably connected in the sliding groove 5;

[0023] The sliding block 6 is installed in an L shape, one end of the slider 3 is rotatably connected to the rotating rod 7, and the other end of the rotating rod 7 is rotatably connected to one end of the sliding block 6. An extrusion roller 8 is fixedly sleeved on the outer wall of the rotating rod 7, and a protective layer is fixedly sleeved on the outer wall of the extrusion roller 8. Through the protective effect of the protective layer, the damage to the iron sheet caused by the extrusion roller 8 can be reduced, thereby improving the processing quality. A rack 9 is fixedly installed on the upper end surface of the base 1, and a gear 10 is fixedly installed on one end of the rotating rod 7. The rack 9 is meshed with the gear 10. Through the above structure, the gear 10 rotates and rolls on the rack 9, driving the extrusion roller 8 to roll and extrude the iron sheet to complete the stretching work. A rotating motor 11 is fixedly installed on the side wall of the base 1. The rotating motor 11 is a prior art that can rotate the object connected to its motor shaft. The motor shaft of the rotating motor 11 rotates through the base 1 and is fixedly connected to one end of the rotating rod 7.

[0024] The detailed working process of this utility model is as follows:

[0025] The staff first uses the table legs 18 and the anti-slip grooves to stably place the device in the designated position, then takes out the iron sheet, places the iron sheet on the platform 16 and turns on the telescopic motor 17. The telescopic motor 17 drives the platform 16 to move upward and drives the iron sheet upward until the iron sheet is close to the squeezing roller 8. At this time, the staff rotates the knob 19 and drives the screw 14 to rotate through the knob 19, so that the limiting block 13 slides downward in the extension block 12 and fixes one end of the iron sheet. At this time, the staff can turn on the rotating motor 11 and drive the threaded rod 4 to rotate through the rotating motor 11, so that the slider 3 slides in the slide groove 2, and the sliding block 6 slides in the sliding groove 5 through the rotating rod 7, and the iron sheet is stretched by the squeezing roller 8. At the same time, the gear 10 on the rotating rod 7 rolls on the rack 9, so that the rotating rod 7 rotates, driving the squeezing roller 8 to rotate. At this time, the squeezing roller 8 rotates while moving forward and stretching to roll and squeeze the iron sheet, thereby flattening the iron sheet, preventing the iron sheet from wrinkling and causing quality degradation, and meeting the staff's usage needs.
