Description

Technical Field

[0001] The present invention relates to the technical field of heating furnaces, and particularly to a uniform heating type forging heating furnace that avoids generating cracks. Background Technique

[0002] Forging is a processing method that uses forging machinery to apply pressure to metal billets, causing plastic deformation to obtain forgings with certain mechanical properties, certain shapes, and dimensions. It is one of the two major components of forging (forging and stamping). Through forging, defects such as as-cast porosity generated during the smelting process of metals can be eliminated, and the microstructure can be optimized. At the same time, due to the preservation of the complete metal streamline, the mechanical properties of forgings are generally better than those of castings made of the same material; forgings are objects in which metal is subjected to pressure and shaped into the required shape or appropriate compressive force through plastic deformation. The forging process can enable metals to build a fine grain structure and improve the physical properties of metals; among them, when performing the forging processing of forgings, a forging heating furnace is required to heat the forgings to make the forgings easy to deform plastically, so as to facilitate the subsequent pressure forging operation of the forgings;

[0003] A forging heating furnace is a device that can heat forgings to be processed, making it convenient for subsequent forging processing of the forging workpieces. However, existing forging heating furnaces usually place the forgings in a heating furnace with a heating device for heating. The forgings are mostly fixed in the heating furnace, and the position is inconvenient to change, which easily leads to uneven heating of the forgings, easily causes cracks and damage to the forgings, and further affects the subsequent forging operation of the forgings. Therefore, we propose a uniform heating type forging heating furnace that avoids generating cracks to solve the above problems. Summary of the Invention

[0029] Embodiment: As Figure 1-8 shown, the present invention provides a uniform heating type forging heating furnace that avoids cracks, including a heating furnace frame 1. A heating furnace cover 2 is provided at the top of the heating furnace frame 1. A clamping frame 11 is integrally formed at the top of the inner wall of the heating furnace frame 1.

By providing the observation window 7, it is convenient to observe the heating condition of the forging body 10 in the heating furnace frame 1 from the outside of the heating furnace frame 1. A hook 8 is fixedly installed at the top end of the heating furnace cover 2. During use, an external lifting device is used to cooperate with the hook 8 to drive the heating furnace cover 2 to lift and lower, so as to facilitate the subsequent feeding and discharging of the forging body 10 from above the heating furnace frame 1, thereby improving the use effect of the entire forging heating furnace. A support frame 9 is fixedly installed at the bottom end of the heating furnace frame 1. By providing the support frame 9, the entire forging heating furnace is supported, thereby improving the stability of the entire forging heating furnace.

[0031] The placing mechanism 3 includes a protective outer frame 31. A rotating frame 39 is fixedly installed at the bottom end of the protective outer frame 31. An inner ring groove 101 that cooperates with the rotating frame 39 is opened on the inner lower wall of the heating furnace frame 1. The rotating frame 39 is slidably clamped in the inner ring groove 101. By providing the rotating frame 39 at the bottom end of the protective outer frame 31 and slidingly clamping the rotating frame 39 in the inner ring groove 101, the stability of the rotation of the protective outer frame 31 in the heating furnace frame 1 is improved; A ball 391 is rotatably clamped at the bottom of the rotating frame 39. By providing the ball 391 at the bottom of the rotating frame 39, the ball 391 contacts the inner wall of the inner ring groove 101, reducing the friction between the rotating frame 39 and the inner ring groove 101, thereby facilitating the sliding of the rotating frame 39 in the inner ring groove 101, and further facilitating the stable rotation of the protective outer frame 31 in the heating furnace frame 1;

[0032] A protective tube 38 is fixedly installed in the middle of the bottom end of the protective outer frame 31. A gear ring 381 is fixedly sleeved at the bottom of the protective tube 38. A driving shaft 382 is rotatably installed on one side of the inner lower wall of the heating furnace frame 1 close to the gear ring 381. A motor 6 is fixedly installed on one side of the bottom end of the heating furnace frame 1 close to the driving shaft 382. The driving end of the motor 6 is coaxially and fixedly installed with the bottom end of the driving shaft 382. During use, by controlling and turning on the motor 6, the driving shaft 382 is driven to rotate forward and backward; A driving gear 383 that meshes with the gear ring 381 is fixedly installed at the top end of the driving shaft 382. By the forward and backward rotation of the driving shaft 382, the driving gear 383 is driven to rotate forward and backward, thereby driving the gear ring 381 to rotate forward and backward, and further driving the protective tube 38 and the protective outer frame 31 to rotate forward and backward;

[0033] A rotating ring 32 is fixedly clamped in the middle of the bottom end of the protective outer frame 31. A fixed column 33 is rotatably clamped in the rotating ring 32. The bottom end of the fixed column 33 is fixedly installed in the middle of the inner lower wall of the heating furnace frame 1. By arranging the rotating ring 32 in the middle of the bottom end of the protective outer frame 31, the protective outer frame 31 can stably rotate outside the fixed column 33. The top of the fixed column 33 extends into the protective outer frame 31. A fixed gear 34 is fixedly installed at the top of the fixed column 33. The fixed gear 34 always remains in a non-rotating state. A plurality of inner shafts 35 distributed in an annular array are rotatably clamped on the inner side of the top end of the protective outer frame 31. A plurality of outer shafts 36 distributed in an annular array are rotatably clamped on the outer side of the top end of the protective outer frame 31. The bottoms of the plurality of inner shafts 35 and outer shafts 36 extend into the protective outer frame 31 and are fixedly installed with moving gears 341. The moving gears 341 on the inner shafts 35 are meshed and connected to the outside of the fixed gear 34. The moving gears 341 on the outer shafts 36 are meshed and connected to the moving gears 341 on the corresponding inner shafts 35. When the protective outer frame 31 rotates forward and backward, it can drive the plurality of inner shafts 35 and outer shafts 36 to rotate forward and backward with the fixed column 33 as the axis. At the same time, the moving gears 341 rotate meshingly outside the fixed gear 34, and the transmission between adjacent moving gears 341 drives the plurality of inner shafts 35 and outer shafts 36 to rotate synchronously. An inner object seat 37 used in cooperation with the forging body 10 is fixedly installed at the top end of the inner shaft 35. An outer object seat 371 used in cooperation with the forging body 10 is fixedly installed at the top end of the outer shaft 36. By arranging a plurality of inner object seats 37 and outer object seats 371, during use, a plurality of forging bodies 10 are placed on the corresponding inner object seats 37 and outer object seats 371. Thus, when the plurality of inner shafts 35 and outer shafts 36 rotate forward and backward with the fixed column 33 as the axis and the plurality of inner shafts 35 and outer shafts 36 rotate synchronously, it drives the plurality of forging bodies 10 to rotate forward and backward with the fixed column 33 as the axis and rotate synchronously, so as to perform rotational heating on the plurality of forging bodies 10 subsequently, thereby uniformly heating the plurality of forging bodies 10, avoiding cracks in the plurality of forging bodies 10, and further improving the overall heating efficiency of the entire heating furnace for the forging.

[0034] The heating assembly 4 includes a heating top ring 41, which is fixedly clamped inside the heating furnace frame 1. A plurality of heating connecting rods 42 are fixedly installed on the heating top ring 41. At the bottom ends of the opposite sides of the heating connecting rods 42, a middle heating frame 43 is fixedly installed. At the bottom end of one side of the heating connecting rod 42 close to the heating top ring 41, an outer heating frame 44 is fixedly installed. The outer heating frame 44 is located outside a plurality of external object seats 371, and the middle heating frame 43 is located between a plurality of external object seats 371 and a plurality of internal object seats 37. During use, the heating top ring 41 is turned on, and through the plurality of heating connecting rods 42, the middle heating frame 43 and the outer heating frame 44 are heated. Thus, the forging bodies 10 on the plurality of internal object seats 37 and the plurality of external object seats 371 are heated in a wrapped manner on the outer surface. With the rotation and self-rotation of the plurality of forging bodies 10, the plurality of forging bodies 10 are effectively and uniformly heated, preventing cracks from occurring in the plurality of forging bodies 10, and further improving the overall heating efficiency of the entire heating furnace for the forging; by providing the heating assembly 4 and cooperating with the object placing mechanism 3, the forging bodies 10 on the plurality of internal object seats 37 and the plurality of external object seats 371 can be heated in a wrapped manner on the outer surface. With the rotation and self-rotation of the plurality of forging bodies 10, the outer surfaces of the plurality of forging bodies 10 are effectively and uniformly heated, preventing cracks from occurring in the plurality of forging bodies 10, and further improving the overall heating efficiency of the entire heating furnace for the forging;

[0035] The auxiliary assembly 5 includes an auxiliary ring frame 51 and a middle column 52. The middle column 52 is fixedly installed in the middle of the inner upper wall of the heating furnace cover 2. A plurality of L-shaped connecting frames 511 distributed in an annular array are fixedly connected to the outer side of the auxiliary ring frame 51. At the top ends of the L-shaped connecting frames 511, telescopic rods 53 are fixedly installed, and the telescopic rods 53 are fixedly installed on the heating furnace cover 2. At the bottom ends of the L-shaped connecting frames 511, clamping mechanisms 512 are fixedly installed, and the forging body 10 is clamped in the clamping mechanisms 512. During use, the heating furnace cover 2 is lifted, and a plurality of forging bodies 10 to be heated are clamped in the corresponding clamping mechanisms 512. Subsequently, the heating furnace cover 2 descends, and the forging body 10 descends in the heating furnace frame 1. At this time, the clamping frame 11 is movably clamped at the bottom of the heating furnace cover 2, and the top end of the clamping frame 11 contacts the bottom end of the sealing gasket frame 13, realizing the sealed connection between the heating furnace frame 1 and the heating furnace cover 2, reducing the loss of heat during the heating of the forging body 10, and thus improving the use effect of the entire heating furnace until the forging body 10 is placed on the corresponding plurality of internal object seats 37 and the plurality of external object seats 371. Subsequently, the clamping is released, the telescopic rods 53 are turned on, and through the L-shaped connecting frames 511, the plurality of clamping mechanisms 512 are lifted away from the internal object seats 37 and the external object seats 371, preventing the clamping mechanisms 512 from being damaged during the heating of the forging body 10, and thus improving the overall use effect of the entire heating furnace;

[0036] A rotating seat 54 is rotatably sleeved at the bottom of the middle column 52. The rotating seat 54 can rotate at the bottom of the middle column 52. An inner heating connecting rod 55 corresponding to the L-shaped connecting frame 511 is fixedly installed on the outer wall of the rotating seat 54. The bottom end of the inner heating connecting rod 55 is fixedly installed with an inner heating frame 56. The inner heating frame 56 is in a spiral structure. When the forging body 10 is clamped and placed on the inner storage seat 37 and the outer storage seat 371, the inner heating frame 56 is located in the forging body 10. By turning on the inner heating frame 56, the inner wall of the forging body 10 can be heated, and then the forging body 10 can be heated comprehensively, thereby improving the heating effect of the forging body 10. A secondary column 57 is fixedly installed in the middle of the top end of the protective outer frame 31. The top end of the secondary column 57 is fixedly installed with a positioning chuck 58. A positioning groove 541 corresponding to the positioning chuck 58 is opened at the bottom end of the rotating seat 54. The positioning chuck 58 can be movably clamped in the positioning groove 541. When the forging body 10 is placed on the inner storage seat 37 and the outer storage seat 371, the positioning chuck 58 is movably clamped in the positioning groove 541. When the protective outer frame 31 rotates forward and backward, the secondary column 57 drives the rotating seat 54 to rotate forward and backward at the bottom of the middle column 52, thereby driving the inner heating frame 56 to rotate forward and backward, so that the positions of the inner heating frame 56 and the forging body 10 remain relatively unchanged, and then the inner heating frame 56 can always heat the inner wall of the forging body 10; by providing the auxiliary assembly 5, it is convenient to clamp, feed and discharge multiple forging bodies 10. When the outer surface of the forging body 10 is uniformly heated, turn on the inner heating frame 56 to make the inner heating frame 56 always heat the inner wall of the forging body 10, and then heat the forging body 10 comprehensively, thereby improving the heating effect of the forging body 10.

[0037] Working principle: During use, an external lifting device is used to cooperate with the hook 8 to lift the heating furnace cover 2, and a plurality of forging bodies 10 to be heated are clamped in the corresponding clamping mechanisms 512. Subsequently, the heating furnace cover 2 is driven to descend, and the forging bodies 10 descend in the heating furnace frame 1. At this time, the clamping frame 11 is movably clamped at the bottom of the heating furnace cover 2, and the top end of the clamping frame 11 contacts the bottom end of the sealing gasket frame 13 to perform a sealed connection between the heating furnace frame 1 and the heating furnace cover 2, reducing the heat dissipation during the heating of the forging body 10, thereby improving the use effect of the entire heating furnace until the forging bodies 10 are placed on the corresponding multiple inner storage seats 37 and multiple outer storage seats 371. Subsequently, the clamping of the forging bodies 10 is released, the telescopic rod 53 is turned on, and the L-shaped connecting frame 511 drives the plurality of clamping mechanisms 512 to rise away from the inner storage seat 37 and the outer storage seat 371 to prevent the clamping mechanisms 512 from being damaged when the forging bodies 10 are heated subsequently;

[0038] When the forging body 10 is clamped and placed on the internal object seat 37 and the external object seat 371, the internal heating frame 56 is located in the forging body 10, and the positioning chuck 58 is movably clamped in the positioning groove 541;

[0039] Subsequently, the heating top ring 41 is turned on, and through a plurality of heating connecting rods 42, the middle heating frame 43 and the outer heating frame 44 are heated. Through the middle heating frame 43 and the outer heating frame 44, the outer surfaces of the forging bodies 10 on the plurality of internal object seats 37 and the plurality of external object seats 371 are heated in a wrapped manner;

[0040] At the same time, the motor 6 is controlled and turned on to drive the drive shaft 382 to rotate forward and backward, driving the drive gear 383 to drive the gear ring 381 to rotate forward and backward, thereby driving the protective tube 38 and the protective outer frame 31 to rotate stably forward and backward. When the protective outer frame 31 rotates forward and backward, it can drive a plurality of inner shafts 35 and outer shafts 36 to rotate forward and backward with the fixed column 33 as the axis. At the same time, the moving gear 341 meshes and rotates outside the fixed gear 34, and the transmission between adjacent moving gears 341 drives a plurality of inner shafts 35 and outer shafts 36 to rotate synchronously, driving a plurality of forging bodies 10 to rotate forward and backward with the fixed column 33 as the axis and rotate synchronously, so as to perform rotary heating on a plurality of forging bodies 10, uniformly heat a plurality of forging bodies 10, and avoid cracks in a plurality of forging bodies 10;

[0041] Among them, when the protective outer frame 31 rotates forward and backward, the auxiliary column 57 drives the rotating seat 54 to rotate forward and backward at the bottom of the middle column 52, thereby driving the internal heating frame 56 to rotate forward and backward, so that the positions of the internal heating frame 56 and the forging body 10 remain relatively unchanged. Furthermore, the internal heating frame 56 can be turned on synchronously. The internal heating frame 56 always heats the inner wall of the forging body 10, and then comprehensively heats the forging body 10, thereby improving the heating effect of the forging body 10;

[0042] After heating is completed, the motor 6, the heating top ring 41 and the internal heating frame 56 are turned off. Subsequently, the telescopic rod 53 is turned on, and through the L-shaped connecting frame 511, a plurality of clamping mechanisms 512 are driven to descend, and the forging body 10 is clamped by the clamping mechanisms 512. Subsequently, the heating furnace cover 2 is raised to drive a plurality of forging bodies 10 to rise out of the heating furnace frame 1 for convenient discharging.
