Description

Technical Field

[0001] The utility model relates to the technical field of heat treatment devices, in particular to a heat treatment device for gear forging. Background Technique

[0002] Existing gears are often heat-treated through induction coils. During heat treatment, first, the gear is placed on the workbench, and the through-hole at the center of the gear shaft is sleeved on the protrusion on the workbench. Then, the cylinder drives the gear fixed on the workbench into the induction coil for heat treatment. The existing heat treatment equipment only has a workbench for heat-treating one gear. After the gear is heat-treated by the heat treatment equipment, the gear on the workbench needs to be removed and replaced with an untreated gear, and multiple gears cannot be continuously heat-treated in sequence. When heat-treating multiple gears, it is too cumbersome and not convenient enough. For this reason, we propose a heat treatment device for gear forging to solve the above problems. Content of the Utility Model

[0007] Preferably, both the left and right sides of the convex block and the left and right sides of the multiple sliding rods are inclined, and the upper side of the convex block is higher than the lower side of the sliding rod at the front end of the turntable.

[0008] Preferably, the fixing component includes multiple groups of bidirectional screws.

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1 - 4 , an embodiment provided by the present invention: a heat treatment device for gear forging, including a frame 1,

[0020] A control panel 2 is arranged on the front side of the frame 1, a motor 3 is fixedly installed inside the lower end of the frame 1, a circulating component is arranged on the output shaft of the motor 3, a heating coil 7 is fixedly installed inside the rear end of the frame 1, a fixing component is arranged on the circulating component, and the moving track of the fixing component is aligned with the heating coil 7. This device fixes multiple gears on the circulating component through the fixing component, drives the circulating component to rotate through the motor 3 to move multiple gears into the heating coil 7, and heat-treats the gears through the heating coil 7.

[0021] Further, the circulating component includes a turntable 4, the turntable 4 is fixedly installed on the output shaft of the motor 3, multiple groups of sliding rods 5 are annularly installed on the turntable 4, support plates 6 are fixedly installed at the upper ends of multiple groups of sliding rods 5, a bump 8 is fixedly installed on the lower inner wall of the frame 1, and limit rings 9 are fixedly installed at the lower ends of multiple groups of sliding rods 5. This structure drives the turntable 4 to rotate through the motor 3, the turntable 4 rotates to move multiple groups of sliding rods 5 and support plates 6 annularly, and when the sliding rods 5 and support plates 6 move into the rear end of the frame 1, they are jacked up by the bump 8, so as to insert the gears fixed on the support plates 6 into the heating coil 7, and the heating coil 7 can heat-treat the gears.

[0022] Further, the left and right sides of the bump 8 and the left and right sides of multiple groups of sliding rods 5 are both inclined, and the upper side of the bump 8 is higher than the lower side of the sliding rod 5 at the front end of the turntable 4. According to the shapes of the left and right sides of the bump 8 and the left and right sides of multiple groups of sliding rods 5, when the lower end of the sliding rod 5 fits with the upper end of the bump 8, the sliding rod 5 slides upward on the inclined surface of the bump 8, and when the lower side of the sliding rod 5 fits with the upper side of the bump 8, the sliding rod 5 and the support plate 6 can be jacked up to insert the gear into the heating coil 7.

[0023] Furthermore, the fixing component includes multiple groups of bidirectional screws 10. Multiple groups of bidirectional screws 10 are respectively rotatably installed on multiple groups of supporting plates 6. Two groups of sliding sleeves 11 are sleeved on multiple groups of bidirectional screws 10 through threads. Four groups of connecting rods 12 are annularly installed on the outer walls of multiple groups of sliding sleeves 11. Four groups of expanding plates 13 are hingedly installed on the eight groups of connecting rods 12 on two groups of sliding sleeves 11. Guide rods 14 are fixedly installed on multiple groups of supporting plates 6. Multiple groups of guide rods 14 are inserted into multiple groups of sliding sleeves 11. In this structure, the gear is sleeved on multiple groups of expanding plates 13. When the bidirectional screw 10 is rotated to drive the two groups of sliding sleeves 11 to slide, the eight groups of connecting rods 12 will drive the four groups of expanding plates 13 to expand and open, so that the gear can be fixed on the supporting plate 6, avoiding displacement when the rotating disc 4 rotates and drives the gear to move.

[0024] Furthermore, the upper sides of multiple groups of bidirectional screws 10 are lower than the lower side of the heating coil 7. The moving trajectories of the bidirectional screws 10 on multiple groups of supporting plates 6 are at the center point of the heating coil 7. According to the positional relationship between the upper sides of multiple groups of bidirectional screws 10 and the lower side of the heating coil 7, when the sliding rod 5 and the supporting plate 6 do not pass through the convex block 8 to resist, when the rotating disc 4 drives the multiple groups of sliding rods 5 and the bidirectional screws 10 on multiple groups of supporting plates 6 to move, the upper ends of the bidirectional screws 10 will not collide with the heating coil 7.

[0025] Furthermore, the outer walls of multiple groups of expanding plates 13 are all diamond-shaped anti-slip patterns, and multiple groups of expanding plates 13 are all arc-shaped. According to the anti-slip patterns on the outer walls of multiple groups of expanding plates 13, when multiple groups of expanding plates 13 are attached to the inner wall of the gear, the friction force between the outer walls of multiple groups of expanding plates 13 and the inner wall of the gear is increased.

[0026] Working principle: When fixing the gear, as Figure 3 and Figure 4 shown, place multiple gears on multiple groups of supporting plates 6, and rotate multiple groups of bidirectional screws 10. The rotation of multiple groups of bidirectional screws 10 drives the two groups of sliding sleeves 11 on multiple groups of bidirectional screws 10 to slide. The two groups of sliding sleeves 11 on multiple groups of bidirectional screws 10 drive the eight groups of connecting rods 12 on the outer walls to rotate, and the eight groups of connecting rods 12 drive the four groups of expanding plates 13 to fit the inner wall of the gear, thus completing the fixation of the gear on the supporting plate 6. When the output shaft of the motor 3 drives the rotating disc 4 to rotate, as Figure 2As shown, the turntable 4 drives multiple groups of sliding rods 5 and multiple groups of supporting plates 6 to move. When the lower ends of the multiple groups of sliding rods 5 move into the rear end of the frame 1, the lower ends of the sliding rods 5 are in contact with the upper ends of the bumps 8. As the turntable 4 drives the sliding rods 5 to move, the sliding rods 5 rise upward on the inclined surfaces of the bumps 8. The lower sides of the sliding rods 5 are in contact with the upper sides of the bumps 8, and the sliding rods 5 drive the supporting plates 6 to rise upward, and insert the gears on the supporting plates 6 into the heating coil 7. The gears are heat-treated by the heating coil 7. When the turntable 4 drives the sliding rods 5 and the supporting plates 6 to move away, the lower ends of the sliding rods 5 move away from the upper sides of the bumps 8, so that the supporting plates 6 and the sliding rods 5 slide downward under the action of the self-weight of the gears, and the gears can slide and disengage from the heating coil 7. The above is the entire working principle of the present invention.

[0027] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention.
