Description

Technical Field

[0001] The utility model relates to the field of ring forgings, in particular to a heat-insulating tool for transferring ring forging blanks. Background Art

[0002] Ring forgings are rolled from billets. The billets need to be heated before rolling, and the billet temperature cannot be lower than the rolling temperature during rolling. Usually, the distance between the billet heating furnace and the rolling mill is relatively close, and short-distance transportation of the billet after heating will not cause the billet temperature to drop too quickly. However, when the heating furnace and the rolling mill are not in the same workshop, long-distance transportation of the billet will cause the billet temperature to drop too quickly, which will affect the rolling quality of the ring forgings. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a ring forging blank transfer and heat preservation tooling which can keep the blank warm.

[0004] In order to solve the above problems, the technical solution adopted by the utility model is: a ring forging blank transfer and insulation tooling, which is characterized in that: it includes: a circular plate seat, a support leg is provided at the bottom of the circular plate seat, and a positioning column is provided in the center of the circular plate seat. When the blank is placed on the circular plate seat, it can be positioned by being fitted on the positioning column. A circular cover is also provided. The inner cavity diameter of the circular cover is 5 to 10 cm larger than the diameter of the circular plate seat. A lifting ear is provided on the top of the circular cover so that the circular cover can be hoisted. After the circular cover covers the outside of the circular plate seat, the blank placed on the circular plate seat can be insulated.

[0005] Furthermore, the aforementioned ring forging blank transfer insulation tooling, wherein: a ceramic wool insulation layer is provided on the inner surface of the circular cover, and the outer side of the positioning column is covered with a ceramic wool insulation layer.

[0007] Furthermore, the aforementioned ring forging blank transfer and insulation tooling, wherein: a plurality of avoidance notches arranged at intervals around the circular plate seat are provided on the outer ring edge of the circular plate seat, and a lifting cross bar corresponding to each avoidance notch is provided at the bottom of the circular cover shell. When the circular cover shell covers the outside of the circular plate seat from top to bottom, each lifting cross bar can avoid the circular plate seat through its corresponding avoidance notch, so that the circular cover shell can cover the outside of the circular plate seat. At this time, after manually rotating the circular cover shell so that each lifting cross bar is staggered with the corresponding avoidance notch, the lifting circular cover shell can be supported under the circular plate seat by each lifting cross bar to lift the circular plate seat.

[0008] Furthermore, the aforementioned ring forging blank transfer and insulation tooling, wherein: positioning grooves corresponding to each lifting cross bar are provided on the lower surface of the circular plate seat, and each lifting cross bar can be positioned by being snapped into the corresponding positioning groove when lifting the circular plate seat.

[0009] Furthermore, the aforementioned ring forging blank transfer and insulation tooling, wherein: a circle of handrails is provided on the outer side of the circular cover, so as to facilitate workers to manually drive the circular cover to rotate through the handrails.

[0010] The advantages of the present invention are as follows: the ring forging blank transfer and insulation tooling can well insulate the blank during the transfer process, so that the temperature of the blank can be maintained above the specified rolling temperature, thereby reducing the reheating of the blank, which can greatly improve production efficiency, reduce production costs, and improve product quality.

[0012] Figure 2 This is a schematic diagram of the three-dimensional structure of the ring forging blank transfer and insulation tooling described in the present invention from another perspective. DETAILED DESCRIPTION

[0013] The present invention will be described in further detail below with reference to specific embodiments and accompanying drawings.

[0014] like Figure 1 、 Figure 2 As shown, the ring forging blank transfer and insulation tooling includes: a circular plate seat 1, a supporting leg 2 is provided at the bottom of the circular plate seat 1, a positioning column 3 is provided at the center of the circular plate seat 1, and the blank 4 can be positioned by being fitted on the positioning column 3 when placed on the circular plate seat 1, and a circular cover shell 5 is also provided. The inner cavity diameter of the circular cover shell 5 is 5 to 10 cm larger than the diameter of the circular plate seat 1, and a lifting ear 6 is provided on the top of the circular cover shell 5 so that the circular cover shell 5 can be hoisted. After the circular cover shell 5 covers the outer side of the circular plate seat 1, it can insulate the blank 4 placed on the circular plate seat 1.

[0015] In this embodiment, a ceramic wool insulation layer is provided on the inner surface of the circular cover 5 , and the outer side of the positioning column 3 is covered with a ceramic wool insulation layer.

[0016] Refractory bricks 7 are laid on the upper surface of the circular plate base 1 , and pads 8 for supporting the blank 4 are also provided. The blank 4 is supported by the pads 8 and then placed on the refractory bricks 7 .

[0017] Four avoidance notches 9 are arranged at intervals around the circular plate seat 1 on the outer ring edge of the circular plate seat 1, and a lifting cross bar 10 corresponding to each avoidance notch 9 is provided at the bottom of the circular cover shell 5. When the circular cover shell 5 covers the outside of the circular plate seat 1 from top to bottom, each lifting cross bar 10 can avoid the circular plate seat 1 through its corresponding avoidance notch 9, so that the circular cover shell 5 can cover the outside of the circular plate seat 1. At this time, after manually rotating the circular cover shell 5 so that each lifting cross bar 10 is staggered with the corresponding avoidance notch 9, the lifting circular cover shell 5 can be supported under the circular plate seat 1 through each lifting cross bar 10 to lift the circular plate seat 1.

[0018] Positioning grooves 11 corresponding to the lifting cross bars 10 are provided on the lower surface of the circular plate seat 1 . When each lifting cross bar 10 lifts the circular plate seat 1 , it can be positioned by being snapped into the corresponding positioning groove 11 .

[0019] A circle of handrails 12 is provided on the outer side of the circular cover 5 , so that workers can conveniently manually drive the circular cover 5 to rotate through the handrails 12 .

[0020] During work, the circular plate seat 1 is placed on the ground, and then the heated blank 4 is placed on the circular plate seat 1 by a forklift, and the positioning column 3 passes through the blank 4 to position the blank 4, and then the circular cover 5 is immediately hoisted to cover the outside of the circular plate seat 1 to keep the blank 4 warm. The circular cover 5 is manually rotated so that each lifting cross bar 10 is staggered with the corresponding avoidance notch 9, and each lifting cross bar 10 is relative to the corresponding positioning groove 11 up and down. Then the circular cover 5 is lifted and supported by each lifting cross bar 10 under the circular plate seat 1 to lift the circular plate seat 1, and then the entire tooling is lifted with the blank 4 onto the transfer vehicle for transfer. Since the circular cover 5 is shielded and insulated during the transfer process, the temperature of the blank 4 drops more slowly.
