Description

Technical Field

[0001] This utility model relates to the technical field of heating and straightening devices, specifically a heating and straightening device for gray cast iron profiles. Background Technology

[0002] Gray cast iron profiles are profiles made of gray cast iron. They have good casting performance and machinability. Gray cast iron contains a large amount of flake graphite, which acts as a crack source in the material, resulting in lower tensile strength and toughness. However, its good shock absorption and wear resistance make it widely used in the manufacture of structural components such as machine tool beds, frames, and housings. Heat straightening of gray cast iron profiles is mainly used to correct the deformation caused by uneven cooling rate, internal stress release or external force during casting or use. Heating can reduce the hardness of the material and increase its plasticity, making it easier to perform straightening operations, ensuring that the dimensional accuracy and shape of the profiles meet the design requirements, and improving the quality and reliability of the products. During the heating and straightening process of columnar gray cast iron profiles, if there are impurities such as oxide scale, oil stains, and rust on the surface of the profile, these impurities will form a heat insulation layer, which will hinder the effective transfer of heat. This will lead to an increase in the temperature difference between the surface and the interior of the profile, resulting in insufficient heating in some areas and overheating in other areas due to excessive heating time, ultimately causing uneven heating. Therefore, a heating and straightening device for gray cast iron profiles is proposed to address the above problems. Utility Model Content

[0003] The purpose of this invention is to provide a heating and straightening device for gray cast iron profiles to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A heating and straightening device for gray cast iron profiles includes a support rotation control assembly, a support lifting control assembly, and a cylindrical gray cast iron profile. A heating and cleaning assembly is installed at one end of the support lifting control assembly. The support rotation control assembly includes a base, with a drive structure fixedly connected to the bottom of the base.

[0005] As a further optimization of this utility model, the base is fixedly connected to the housing of the servo motor, the main shaft of the servo motor is fixedly connected to the bottom end of the transmission shaft column through a through hole inside the base, and a gap is provided between the bottom end of the transmission shaft column and the top end of the base.

[0006] As a further optimization of this utility model, the top end of the drive shaft extends out of the upper end of the cylindrical shell, and a plurality of guide plates are fixedly connected to the top end of the cylindrical shell. The upper end of the guide plate protrudes from the top end of the drive shaft, and there is a clearance fit between the guide plate and the drive shaft. A cylindrical gray cast iron profile is placed on the top end of the drive shaft, and the guide plate limits the movement of the cylindrical gray cast iron profile.

[0007] As a further optimization of this utility model, the top of the arch frame is fixedly connected to the cylinder body of the electric hydraulic cylinder and the cylinder body of the servo electric cylinder, the piston rod of the electric hydraulic cylinder and the piston rod of the servo electric cylinder both slide inside the arch frame, and the bottom of the arch frame is fixedly connected to the top of the base.

[0010] As a further optimization of this utility model, the heating unit includes a protective sleeve, a spiral heat radiation tube, and a flexible wire. The spiral heat radiation tube extends to one end of the first and second slots, and a heat dissipation gap is left between the spiral heat radiation tube and the upper and lower frame plates.

[0011] Compared with the prior art, the beneficial effects of this utility model are: In this invention, the device effectively removes impurities such as oxide scale, oil stains, and rust from the surface of gray cast iron profiles through the provided support lifting control component and heating cleaning component.

[0016] Please see Figures 1-6 This utility model provides a technical solution: A heating and straightening device for gray cast iron profiles includes a support rotation control assembly 1, a support lifting control assembly 2, and a cylindrical gray cast iron profile 3. A heating and cleaning assembly 4 is installed at one end of the support lifting control assembly 2. The support rotation control assembly 1 includes a base 11, with a drive structure fixedly connected to the bottom end of the base 11. A cylindrical shell 13 is fixedly connected to the top end of the support rotation control assembly 1, and a transmission shaft column 14 is rotatably connected to the inner side of the cylindrical shell 13. The support lifting control assembly 2 includes an arch frame 21, with the top end of the arch frame 21 fixedly connected to the drive structure. A cylinder base 24 is connected, and a turntable 25 is rotatably connected to the inner side of the cylinder base 24. The heating and cleaning assembly 4 includes an upper frame plate 41. A first set of grooves 42 is opened on the inner side of the upper frame plate 41. A positioning seat 45 and a connecting piece 46 are fixedly connected to the bottom end of the upper frame plate 41. A heating unit 44 is fixedly connected to the inner side of the positioning seat 45. A lower frame plate 47 is fixedly connected to the bottom end of the connecting piece 46. A steel bar 43 is fixedly connected to the inner side of the lower frame plate 47 through a second set of grooves 48. The lower frame plate 47 is fitted onto the outside of the columnar gray cast iron profile 3 through the second set of grooves 48.

[0017] As a further implementation of this solution, the base 11 is fixedly connected to the housing of the servo motor 12. The main shaft of the servo motor 12 is fixedly connected to the bottom end of the drive shaft column 14 through a through hole inside the base 11. A gap is provided between the bottom end of the drive shaft column 14 and the top end of the base 11. The top end of the drive shaft column 14 extends out of the upper end of the cylindrical shell 13. Multiple guide plates 15 are fixedly connected to the top end of the cylindrical shell 13. The upper end of the guide plates 15 protrudes from the top end of the drive shaft column 14. There is a clearance fit between the guide plates 15 and the drive shaft column 14. A cylindrical gray cast iron profile 3 is placed, and a guide plate 15 limits the cylindrical gray cast iron profile 3. Through the above settings, this distance provides a safe space for the rotation of the drive shaft column 14, effectively avoiding friction or interference between the drive shaft column 14 and the base 11 when rotating at high speed, ensuring transmission stability and equipment life. The guide plate 15 is used to initially limit the radial position of the cylindrical gray cast iron profile 3, which, combined with the support at the top of the drive shaft column 14, realizes the rapid initial centering of the cylindrical gray cast iron profile 3, laying the foundation for subsequent precise pressing. As a further implementation of this solution, the top of the arch frame 21 is fixedly connected to the cylinder body of the electric hydraulic cylinder 22 and the cylinder body of the servo electric cylinder 23. The piston rods of the electric hydraulic cylinder 22 and the piston rods of the servo electric cylinder 23 slide inside the arch frame 21. The bottom of the arch frame 21 is fixedly connected to the top of the base 11. Through the above arrangement, this layout integrates the drive unit electric hydraulic cylinder 22 and servo electric cylinder 23 onto a unified support structure arch frame 21, and fixes it to the base 11 through the arch frame 21, ensuring that the entire pressing and cleaning module has extremely high rigidity and stability, and is not prone to shaking during operation. As a further implementation of this solution, the piston rod end of the electric hydraulic cylinder 22 is fixed to the cylinder seat 24, the turntable 25 presses the top of the cylindrical gray cast iron profile 3, and the piston rod end of the servo electric cylinder 23 is fixedly connected to the top of the upper frame plate 41. Through the above settings, the connection method realizes that the electric hydraulic cylinder 22 drives the cylinder seat 24 and the turntable 25 to vertically press the cylindrical gray cast iron profile 3, and the servo electric cylinder 23 drives the heating and cleaning assembly 4 to vertically lift and lower the whole. The power transmission is direct and the action control is precise, so that the steel bar 43 contacts the cylindrical gray cast iron profile 3, and then the servo motor 12 is started to rotate the cylindrical gray cast iron profile 3, thereby realizing the cleaning work. As a further implementation of this solution, the opening diameter of the first set of grooves 42 is the same as that of the second set of grooves 48. The first set of grooves 42 and the second set of grooves 48 are aligned vertically. The diameter of the first set of grooves 42 is 1.5 times the outer diameter of the cylinder seat 24, and the diameter of the second set of grooves 48 is 1.1 times the outer diameter of the cylinder shell 13. Through the above settings, this size design ensures that during the up-and-down movement of the heating cleaning assembly 4, its key components such as steel bars 43 and heating units 44 can pass smoothly or be fitted onto the outside of components such as the columnar gray cast iron profile 3, the cylinder shell 13 and the cylinder seat 24. This not only ensures the realization of the function but also avoids motion interference and improves the reliability of operation. As a further implementation of this solution, the heating unit 44 includes a protective sleeve, a spiral radiant heat tube, and a flexible cord. The spiral radiant heat tube extends to one end of the first slot 42 and the second slot 48. A heat dissipation gap is maintained between the spiral radiant heat tube and the upper frame plate 41 and the lower frame plate 47. This design, with its protective sleeve and heat dissipation gap, protects the spiral radiant heat tube from mechanical damage and promotes air circulation, effectively preventing heat accumulation inside the device, ensuring heating efficiency, and extending the component's lifespan. The flexible cord provides the heating unit 44 with necessary flexibility to accommodate its movement during operation.

[0018] Workflow: When fixing the cylindrical gray cast iron profile 3, the electric hydraulic cylinder 22 drives the cylinder seat 24 and the turntable 25 to approach the upper part of the arch frame 21, thus leaving space for the placement of the cylindrical gray cast iron profile 3. At the same time, the heating and cleaning assembly 4 moves towards the upper end of the arch frame 21 when driven by the servo cylinder 23. The soft wire at the front end of the heating unit 44 will bend to a certain extent, which does not affect the normal movement of the heating and cleaning assembly 4. The cylindrical gray cast iron profile 3 is placed on the upper end of the drive shaft column 14. At the same time, the chamfering of the guide plate 15 makes it easy to align the center of the lower end of the cylindrical gray cast iron profile 3 with the center of the upper end of the drive shaft column 14. At this time, the electric hydraulic cylinder 22 is started to drive the cylinder seat 24 and the turntable 25 to move downward until the bottom end of the turntable 25 is in close contact with the top end of the cylindrical gray cast iron profile 3, thereby achieving the effect of pressing and fixing the cylindrical gray cast iron profile 3. Then, the servo cylinder 23 is activated to drive the heating and cleaning assembly 4 to move downwards. At this time, the second set of slots 48 opened on the lower frame plate 47 first fits onto the outside of the cylindrical gray cast iron profile 3. At this time, the steel bar 43 will contact the outside of the cylindrical gray cast iron profile 3. Then, the servo motor 12 is activated, and the servo motor 12 drives the drive shaft column 14 to rotate. The drive shaft column 14 is rotatably connected to the inside of the cylindrical shell 13. Through the frictional force of the contact between the drive shaft column 14, the cylindrical gray cast iron profile 3 and the turntable 25, the drive shaft... When column 14 rotates, column gray cast iron profile 3 and turntable 25 will rotate simultaneously. In this way, turntable 25 will rotate inside cylinder seat 24. Through the friction between steel strip 43 and the outside of column gray cast iron profile 3, it can clean the oxide scale, oil stains and rust and other impurities on the outside of column gray cast iron profile 3. During the cleaning process, the impurities are removed by a blower. Then, the servo electric cylinder 23 controls the heating cleaning component 4 to move downward as a whole, so as to achieve the effect of thoroughly cleaning the surface of column gray cast iron profile 3. When the shape of the columnar gray cast iron profile 3 is heated and corrected, the heating and cleaning assembly 4 is moved downward as a whole by the servo electric cylinder 23 until the bottom end of the lower frame plate 47 is in contact with the top end of the cylinder shell 13. At this time, the steel strip 43 will contact the part of the drive shaft column 14 that protrudes from the cylinder shell 13, and the second set of grooves 48 will move away from the columnar gray cast iron profile 3. At this time, the spiral heat radiation tube at the rear end of the heating unit 44 will be sleeved on the outside of the columnar gray cast iron profile 3. Then, by starting the servo motor 12, the columnar gray cast iron profile 3 is controlled to rotate. This can further improve the uniformity of heating the columnar gray cast iron profile 3 and reduce the phenomenon of reduced shape correction quality of the columnar gray cast iron profile 3 due to uneven heating. At this time, the heating unit 44 is powered on to heat the spiral heat radiation tube and heat the columnar gray cast iron profile 3 through heat radiation. When correcting the shape of the columnar gray cast iron profile 3, after the columnar gray cast iron profile 3 is heated for a certain period of time, the heating and cleaning assembly 4 continues to move downwards under the control of the servo electric cylinder 23. At this time, although the steel bar 43 will contact the outside of the cylinder shell 13, it will not affect the movement of the lower frame plate 47. The first set of grooves 42 opened on the upper frame plate 41 will pass through the outside of the columnar gray cast iron profile 3 until the upper frame plate 41 is located at the lower end of the columnar gray cast iron profile 3. At this time, the columnar gray cast iron profile 3 is then manually tapped to apply pressure to the columnar gray cast iron profile 3, thereby correcting the shape of the columnar gray cast iron profile 3.

[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
