Description

Technical Field

[0001] This utility model relates to a gear shaft forging die, specifically a gear shaft forging die that facilitates demolding, and belongs to the field of gear shaft forging technology. Background Technology

[0002] Gear shaft forging dies typically consist of an upper die, a lower die, and related positioning, guiding, and ejection mechanisms. The upper and lower dies each have identical forming modules to shape the gear shaft. The design of these forming modules must precisely match the dimensions and shape requirements of the gear shaft. Free forging is one of the earliest and most commonly used forging methods in gear shaft manufacturing. This method uses hammering, impact, or pressing to cause plastic deformation of the metal material, thereby forming the desired shape and size. Die forging is a method of forging within a die. This method constrains and shapes the workpiece using the die, thereby precisely controlling the shape and dimensions of the gear shaft forging die.

[0003] In the prior art, such as the gear shaft forging fixture for oil drilling equipment disclosed in CN212598647U, there is a die base, a lower die on the die base, an upper die movably connected to the lower die, a pad between the lower die and the die base, and a cavity matching the gear shaft inside the lower die. A pressure plate is fitted on the lower die, and a locking element is provided on the pressure plate, which passes through the pad and connects to the die base. A push rod matching the gear shaft is provided at the lower part of the die base. Its structural design is simple and reasonable, easy to manufacture and low in cost, with high working efficiency. Furthermore, by setting the lower die into a three-section structure, it is easy to assemble the entire forging fixture and convenient to use.

[0004] The above-mentioned technical solution has high working efficiency, and by setting the lower die into a three-section structure, it is easy to assemble the entire forging fixture and is convenient to use. However, when using it, it is inconvenient to remove the workpiece after forging, which makes material removal troublesome and inconvenient to use. In view of this, a gear shaft forging die with convenient demolding is provided to overcome the above defects. Utility Model Content

[0005] This utility model provides a gear shaft forging die that facilitates easy demolding, addressing the problem that after forging, it is inconvenient to remove the workpiece, leading to difficulties in material handling and usability.

[0006] The present invention achieves the above objectives through the following technical solution: a gear shaft forging mold that facilitates mold release, comprising a mold body, an upper fixing plate fixed on the upper surface of the mold body, a forging pressing mechanism for forging the workpiece provided inside the mold body, and a driving mechanism for driving the forging pressing mechanism on the upper surface of the upper fixing plate.

[0007] The forging mechanism includes a forging chamber, which is located on the upper surface of the mold body. An ejector rod is telescopically connected inside the forging chamber. A movable plate is fixed to the lower surface of the ejector rod. A drive electric cylinder, which is fixedly connected to the mold body, is fixed to the lower surface of the movable plate.

[0008] As a further embodiment of this utility model: the driving mechanism includes a mounting plate, which is fixed to the upper surface of the upper fixing plate, and a drive motor is fixed to the side wall of the mounting plate by bolts.

[0009] As a further embodiment of this utility model: the power output shaft of the drive motor is fixed with a drive disk, and the side wall of the drive disk is fixed with a hinge rod.

[0010] As a further embodiment of this utility model: the outer surface of the hinge rod is rotatably connected to a movable rod, the end of the movable rod is hinged to a forging head, and the upper surface of the forging head is provided with a cleaning mechanism for cleaning the mold.

[0011] As a further embodiment of this utility model: the cleaning mechanism includes piston rods, and there are two piston rods. Both piston rods are fixed on the upper surface of the forging head, and piston tubes are telescopically connected to the ends of the two piston rods.

[0012] As a further embodiment of this utility model: the upper surface of the piston tube is connected to a one-way valve, the outer wall of the piston tube is connected to a connecting pipe, and the end of the connecting pipe is connected to an air jet component fixed on the mold body.

[0013] As a further improvement of this utility model: a collection box is installed at one end of the mold body, and a slot is inserted into the side wall of the collection box.

[0014] The beneficial effects of this utility model are: the drive motor drives the drive disk to rotate, which causes the hinge rod to drive the movable rod to move, and drives the forging head to move towards the mold body, which can forge the blank placed in the forging cavity and can repeatedly forge the blank.

[0015] The jetting component sprays air onto the upper surface of the mold body, which in turn blows out the waste slag generated during forging on the mold body, allowing the waste slag to enter the collection box. After the billet forging is completed, the drive cylinder drives the movable plate to move vertically, which in turn drives the ejector rod to eject the workpiece from the forging chamber.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0022] like Figures 1 to 4 As shown, a gear shaft forging die that is easy to demold includes a die body 1, an upper fixing plate 2 fixed on the upper surface of the die body 1, a forging mechanism for forging the workpiece is provided inside the die body 1, and a driving mechanism for driving the forging mechanism is provided on the upper surface of the upper fixing plate 2.

[0023] The forging mechanism includes a forging chamber 3, which is located on the upper surface of the mold body 1. An ejector rod 31 is telescopically connected inside the forging chamber 3. A movable plate 32 is fixed to the lower surface of the ejector rod 31. A drive cylinder 33, fixedly connected to the mold body 1, is fixed to the lower surface of the movable plate 32. The drive mechanism includes a mounting plate 4, which is fixed to the upper surface of the upper fixed plate 2. A drive motor 41 is bolted to the side wall of the mounting plate 4. A drive disk 42 is fixed to the power output shaft of the drive motor 41. A hinge rod 43 is fixed to the side wall of the drive disk 42. A movable rod 44 is rotatably connected to the outer surface of the hinge rod 43. The end of 4 is hinged to a forging head 45. The upper surface of the forging head 45 is provided with a cleaning mechanism for cleaning the mold. The blank is placed in the forging chamber 3. The mounting plate 4 is fixed on the upper fixed plate 2. Then, the drive motor 41 set on the mounting plate 4 can drive the drive disk 42 to rotate, so that the hinge rod 43 drives the movable rod 44 to move. At this time, the movable rod 44 is driven to move vertically, thereby driving the forging head 45 to move towards the mold body 1, so as to forge the blank placed in the forging chamber 3. Furthermore, the drive motor 41 can repeatedly forge the blank by continuously driving the drive disk 42 to rotate. Example 2

[0024] In addition to all the technical features in Embodiment 1, this embodiment also includes: a cleaning mechanism comprising piston rods 5, of which two piston rods 5 are provided, both piston rods 5 being fixed to the upper surface of the forging head 45. The ends of the two piston rods 5 are telescopically connected to piston tubes 51. A one-way valve 52 is connected to the upper surface of the piston tubes 51. A connecting pipe 53 is connected to the outer wall of the piston tubes 51. An air jet component 54 fixed to the mold body 1 is connected to the end of the connecting pipe 53. A collection box 6 is installed at one end of the mold body 1. A slot 7 is inserted into the side wall of the collection box 6. When the forging head 45 moves vertically, it can drive the piston rods 5 to move inside the piston tubes 51. When the piston rods 5 move downwards... With the cooperation of the one-way valve 52, external air is drawn into the piston tube 51. When the piston rod 5 moves upward, it compresses the air inside the piston tube 51. The compressed air enters the jetting component 54 through the connecting pipe 53, causing the jetting component 54 to spray air onto the upper surface of the mold body 1, thereby blowing out the waste slag generated during forging on the mold body 1. The waste slag enters the collection box 6. With the help of the set slot 7, the collection box 6 can be easily disassembled and cleaned, making it convenient to use. After the billet forging is completed, the drive cylinder 33 drives the movable plate 32 to move vertically, thereby driving the ejector rod 31 to eject the workpiece in the forging chamber 3.

[0025] Working principle: Before using this easy-to-unload gear shaft forging die, first place the die body 1 in a suitable position. During use, place the blank into the forging chamber 3. An mounting plate 4 is fixed to the upper fixing plate 2. Then, the drive motor 41 on the mounting plate 4 drives the drive disc 42 to rotate, causing the hinge rod 43 to drive the movable rod 44 to move. At this time, the movable rod 44 is driven to move vertically, thereby driving the forging head 45 towards the die body 1, which can forge the blank placed in the forging chamber 3. Furthermore, by continuously driving the drive disc 42 to rotate, the drive motor 41 can repeatedly forge the blank. When the forging head 45 moves vertically, it can drive the piston rod 5 in the piston tube 51. Internally, when the piston rod 5 moves downward, with the cooperation of the one-way valve 52, external air is drawn into the piston tube 51. When the piston rod 5 moves upward, it compresses the air inside the piston tube 51. The compressed air enters the jetting component 54 through the connecting pipe 53, causing the jetting component 54 to spray air onto the upper surface of the mold body 1, thereby blowing out the waste slag generated during forging on the mold body 1. The waste slag enters the collection box 6, and with the help of the set slot 7, the collection box 6 can be easily disassembled and cleaned for easy use. After the billet forging is completed, the drive cylinder 33 drives the movable plate 32 to move vertically, thereby driving the ejector rod 31 to eject the workpiece in the forging chamber 3.
