Description

Technical Field

[0001] The utility model relates to the technical field of thick-wall head processing, in particular to a device for preventing deformation during heat treatment of thick-wall heads. Background Technique

[0002] During the manufacturing process of petrochemical equipment, for head components, especially when encountering a large diameter and strict requirements for the ovality in the later production, during hot processing, temporary supports are generally used for multi-point support, which can achieve the effect of reducing deformation. However, due to the large-scale and refinement of the petrochemical industry, the requirements for head manufacturing and later assembly are getting higher and higher. Once the large-thickness head shows ovality, it is very difficult to repair it later. Multi-point support and the unevenness of the heating furnace carriages will both cause the head to be oval, and this method obviously can no longer meet the current usage requirements.

[0003] For example, the utility model with the application number 201620195891.5 discloses a device for preventing deformation during heat treatment of thick-wall heads. The upper end surface of this device expands and contracts with the head during heat treatment, and is not restricted by the contact points of the supports, which is convenient for its placement on the furnace carriage; the support plate is suitable for surface contact with various models and sizes of heads, greatly improving the utilization rate of the tooling. This device not only ensures uniform full coverage of heating, reduces the ovality of the head, and significantly improves the processing quality, but also has a simple structure, low manufacturing cost, easy operation, can be reused, and improves productivity.

[0004] The similar applications currently still have deficiencies:

[0005] This kind of device for preventing deformation during heat treatment of thick-wall heads directly places the thick-wall head on the support plate, but its size is fixed and cannot be adjusted according to the different sizes and wall thicknesses of the thick-wall heads, with poor flexibility in use. And directly placing the head on the support plate requires multiple alignments and position corrections to accurately clamp and place the head on the support plate, which is very inconvenient to use.

[0006] Therefore, a device for preventing deformation during heat treatment of thick-wall heads is designed to optimize the above problems. Content of the Utility Model

[0007] The main purpose of the utility model is to provide a device for preventing deformation during heat treatment of thick-wall heads to solve the related technical problems raised in the above background technique.

[0008] The purpose of the utility model can be achieved by adopting the following technical solutions:

[0009] A heat treatment anti-deformation device for a thick-walled head, comprising a fixed disk. The top of the fixed disk is evenly provided with sliding holes. A first bevel gear is rotatably installed at the middle position of the bottom of the fixed disk. A support plate is fixed to the bottom of the fixed disk. Adjusting shafts are evenly and rotatably connected inside the support plate. Second bevel gears are fixed to one ends of the adjusting shafts close to the first bevel gear, and the second bevel gears are meshed with the first bevel gear. Sliders are threadedly connected to the outer sides of the adjusting shafts, and the tops of the sliders penetrate through the sliding holes and extend to the top of the fixed disk. A support mechanism is arranged on the tops of the sliders. A worm gear is fixed to the bottom of the first bevel gear. A worm is installed through one side of the support plate, and the worm is meshed with the worm gear.

[0010] Preferably: The support mechanism includes an elastic plate and a sliding seat. The sliding seat is located at the top end of the slider. An elastic plate is fixed to the top of the sliding seat. Adjusting rods are rotatably installed on one sides of the elastic plate. Adjusting blocks are threadedly installed on the outer sides of the adjusting rods. Push rods are hinged to both sides of the adjusting blocks, and one ends of the push rods are hinged to one side of the elastic plate.

[0011] Preferably: A support rod is fixed to the middle position of the top of the fixed disk. A sleeve is sleeved on the outer side of the support rod. A spring is sleeved on the outer side of the support rod and at the bottom of the sleeve. A support block is fixed to the top of the sleeve.

[0012] Preferably: A grip ring is fixed to one end of the adjusting rod, and the grip ring is a high-temperature resistant grip ring.

[0014] Preferably: The top of the support block is set as an arc surface, and a protective layer is arranged on the top of the support block.

[0015] The beneficial effects of the present utility model are:

[0016] The heat treatment anti-deformation device for a thick-walled head provided by the present utility model, through the combined use of a fixed disk, sliding holes, a first bevel gear, adjusting shafts, second bevel gears, a worm gear, a worm, sliders and a support plate, can adjust the position of the elastic plate according to the size of the head, which can not only be applicable to different thick-walled heads, but also does not require manual position correction, achieving the purpose of more efficient and flexible use, thereby improving the practicability and convenience of the heat treatment anti-deformation device for the thick-walled head;

[0017] Through the combined use of an elastic plate, a sliding seat, an adjusting rod, an adjusting block and a push rod, rotating the adjusting rod forward and backward makes the adjusting block reciprocate along the adjusting rod, thereby pushing or pulling the push rod to move, so that one end of the push rod pushes the two ends of the elastic plate to bend or flatten, which can better fit the inner wall of the head, increasing the fitting area with the inner wall of the head, thus improving the practicability of the anti-deformation device for heat treatment of the thick-walled head;

[0018] Through the combined use of a support rod, a sleeve, a spring and a support block, place the thick-walled head on the fixed disk, the inner top wall of the head contacts the top of the support block, so that the support block provides preliminary support for the thick-walled head. Under the elastic force of the spring, the impact of the head directly falling onto the fixed disk can be reduced, making the placement and installation more stable, thus facilitating the processing of the thick-walled head.

A support plate 10 is fixed to the bottom of the fixed disk 1. Adjusting shafts 4 are uniformly and rotatably connected inside the support plate 10. Second bevel gears 5 are fixed to one ends of the adjusting shafts 4 close to the first bevel gear 3, and the second bevel gears 5 are meshed with the first bevel gear 3. Sliders 8 are threadedly connected to the outer sides of the adjusting shafts 4, and the tops of the sliders 8 penetrate through the sliding holes 2 and extend to the top of the fixed disk 1. A support mechanism 9 is arranged at the top of the slider 8. A worm gear 6 is fixed to the bottom of the first bevel gear 3. A worm 7 is installed through one side of the support plate 10, and the worm 7 is meshed with the worm gear 6. The support mechanism 9 includes an elastic plate 11 and a sliding seat 12. The sliding seat 12 is located at the top end of the slider 8. An elastic plate 11 is fixed to the top of the sliding seat 12. Adjusting rods 13 are rotatably installed on one sides of the elastic plate 11. Adjusting blocks 14 are threadedly installed on the outer sides of the adjusting rods 13. Push rods 15 are hinged to both sides of the adjusting blocks 14, and one ends of the push rods 15 are hinged to one side of the elastic plate 11.

[0027] The thick-walled head is placed on the fixed disk 1 with the port facing down by a crane. The worm 7 is rotated to drive the worm gear 6 and the first bevel gear 3 to rotate. The first bevel gear 3 drives the second bevel gear 5 and the adjusting shafts 4 to rotate. Then, the sliders 8 on the adjusting shafts 4 drive the sliding seats 12 to move outward until they fit against the inner wall of the head and correct the position of the head. The adjusting rods 13 are rotated forward and backward to make the adjusting blocks 14 reciprocate along the adjusting rods 13, thereby pushing or pulling the push rods 15 to move, so that one end of the push rod 15 pushes the two ends of the elastic plate 11 to bend or flatten, which can fit more closely to the inner wall of the head and increase the fitting area with the inner wall of the head.

[0028] Embodiment Two
