Description

Technical Field

[0001] This utility model relates to the field of flange forging technology, and in particular to a high-strength alloy steel flange forging device. Background Technology

[0002] During the forging process of alloy steel flanges, non-metallic inclusions can affect the properties of the alloy steel. Therefore, in order to forge high-strength alloy steel flanges, existing technologies typically remove some non-metallic inclusions from the alloy steel material during the raw material preparation stage. The removed alloy steel material is then placed in a heating device for thorough heating, and finally, the heated and formed alloy steel flange is placed in a forging device for repeated hammering and forging. However, existing flange forging devices still have the following problems in actual use:

[0003] Firstly, the reciprocating forging hammer can usually only hammer a small area of ​​the alloy steel flange, which will result in uneven force on the surface of the alloy steel flange and make it impossible to hammer and forge the surface of the alloy steel flange sufficiently and evenly, thus affecting the quality of the forging.

[0004] Secondly, after forging, the formed alloy steel flange is prone to getting stuck in the mold, making it difficult to demold, thus reducing demolding efficiency. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-strength alloy steel flange forging device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

A hydraulic cylinder is fixed to the top outer wall of the mounting rod by bolts, and a forging hammer is fixedly connected to the bottom end of the piston rod of the hydraulic cylinder.

[0008] The L-shaped support frame is connected to a hollow rotating seat via a rotating mechanism. The top outer wall of the hollow rotating seat is fixed with a flange forming mold by bolts, and the hollow rotating seat is equipped with a material ejection and demolding mechanism.

[0009] The rotating mechanism includes a gear transmission box fixedly connected to the bottom outer wall of the L-shaped support frame, a rotating shaft rotatably mounted through the gear transmission box, a stepper motor fixedly mounted to the side wall of the gear transmission box by bolts, a driving bevel gear fixedly mounted on the output shaft of the stepper motor, and a driven bevel gear fixedly mounted on the bottom end of the rotating shaft.

[0010] Preferably, the output shaft of the stepper motor passes through one side of the gear transmission box, the driving bevel gear and the driven bevel gear mesh with each other and are both located inside the gear transmission box, and the top of the rotating shaft is coaxially welded to the bottom of the hollow rotating seat.

[0012] Preferably, the control assembly includes a control shaft that is rotatably mounted through the hollow rotating seat, a worm gear fixedly mounted on the control shaft, and a worm wheel fixedly mounted on the lower part of the lifting screw.

[0014] Preferably, the top center of the hollow rotary seat and the bottom center of the flange forming mold are provided with a top material channel that is adapted to and slidably connected to the lifting bar.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. A rotating mechanism is provided to allow the alloy steel flange placed in the flange forming mold to rotate at a uniform speed. Then, the piston rod of the hydraulic cylinder controls the forging hammer to reciprocate and continuously hammer the uniformly rotating alloy steel flange to make the surface of the flange evenly stressed.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1, referring to Figure 1 and Figure 3 A high-strength alloy steel flange forging device includes a mounting rod 2 welded to the upper outer wall of one side of an L-shaped support frame 1;

[0026] In this embodiment, a hydraulic cylinder 3 is fixed to the top outer wall of the mounting rod 2 by bolts, and a forging hammer 4 is fixedly connected to the bottom end of the piston rod of the hydraulic cylinder 3. An avoidance hole for the extension and retraction of the piston rod of the hydraulic cylinder 3 is provided on the mounting rod 2.

[0027] In this embodiment, a hollow rotating seat 5 is connected to the L-shaped support frame 1 via a rotating mechanism, and a flange forming mold 6 is fixed to the top outer wall of the hollow rotating seat 5 by bolts.

[0028] Specifically, the rotating mechanism includes a gear transmission box 7 fixedly connected to the bottom outer wall of the L-shaped support frame 1, a rotating shaft 8 rotatably mounted through the gear transmission box 7, a stepper motor 9 fixedly mounted to the side wall of the gear transmission box 7 by bolts, a driving bevel gear 10 fixedly mounted on the output shaft of the stepper motor 9, and a driven bevel gear 11 fixedly mounted on the bottom end of the rotating shaft 8.

[0029] Furthermore, the output shaft of the stepper motor 9 passes through one side of the gear transmission box 7, the driving bevel gear 10 and the driven bevel gear 11 mesh with each other and are both located inside the gear transmission box 7, and the top of the rotating shaft 8 is coaxially welded to the bottom of the hollow rotating seat 5.

[0030] In this embodiment, the heat-treated alloy steel flange is placed into the flange forming mold 6. The stepper motor 9 drives the active bevel gear 10 to rotate. Subsequently, the driven bevel gear 11, which meshes with the active bevel gear 10, drives the hollow rotating seat 5 at the top of the rotating shaft 8 to rotate. This causes the alloy steel flange placed in the flange forming mold 6 to rotate at a uniform speed. Then, the piston rod of the hydraulic cylinder 3 controls the forging hammer 4 to reciprocate and continuously hammer the uniformly rotating alloy steel flange to make its surface uniformly stressed. This facilitates the full and uniform hammering and forging of the alloy steel flange surface, improving the forging quality.

[0031] Example 2, refer to Figure 2 and Figure 4-5 This embodiment is an optimization based on embodiment 1. Specifically, the hollow rotary seat 5 is equipped with an ejector demolding mechanism.

[0032] More specifically, the ejector mechanism includes a lifting screw 12 rotatably mounted in the hollow rotating seat 5, a control component, and a lifting square bar 13 threadedly connected to the lifting screw 12;

[0033] Furthermore, the control assembly includes a control shaft 15 that is rotatably mounted through the hollow rotating seat 5, a worm gear 16 fixedly mounted on the control shaft 15, and a worm wheel 17 fixedly mounted on the lower part of the lifting screw 12. The worm gear 16 and the worm wheel 17 mesh with each other and are both located inside the hollow rotating seat 5. A handwheel 18 is fixedly connected to the outer wall of one end of the control shaft 15.

[0034] Furthermore, a top material channel 14 adapted to and slidably connected to the lifting square bar 13 is provided at the top center of the hollow rotating seat 5 and the bottom center of the flange forming mold 6. Through the limiting effect of the top material channel 14, it is easy to ensure that the lifting square bar 13, which is threadedly connected to the lifting screw 12, can achieve stable linear movement.

[0035] In this embodiment, after forging is completed, the worm gear 16 on the control shaft 15 is driven to rotate by the handwheel 18. Then, the worm wheel 17 meshing with the worm gear 16 will drive the lifting screw 12 to rotate. Subsequently, the lifting square bar 13 threadedly connected to the lifting screw 12 will push the alloy steel flange formed in the flange forming mold 6 upward through the two ejector channels 14 in sequence, thereby facilitating demolding and effectively improving demolding efficiency.

[0036] Working principle: First, the heat-treated alloy steel flange is placed into the flange forming mold 6. The stepper motor 9 drives the active bevel gear 10 to rotate. Then, the driven bevel gear 11, which meshes with the active bevel gear 10, drives the hollow rotating seat 5 at the top of the rotating shaft 8 to rotate. This causes the alloy steel flange placed in the flange forming mold 6 to rotate at a uniform speed. Then, the piston rod of the hydraulic cylinder 3 controls the forging hammer 4 to reciprocate and continuously hammer the uniformly rotating alloy steel flange to make its surface evenly stressed. This facilitates the full and uniform hammering and forging of the alloy steel flange surface, improving the forging quality.

[0037] Secondly, after forging is completed, the worm gear 16 on the control shaft 15 is driven to rotate by the handwheel 18. Then, the worm wheel 17 meshing with the worm gear 16 will drive the lifting screw 12 to rotate. Subsequently, the lifting square bar 13 threadedly connected to the lifting screw 12 will push the alloy steel flange formed in the flange forming mold 6 upward through the two ejector channels 14 in sequence, thereby facilitating demolding and effectively improving demolding efficiency.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
