Abstract
Description
Technical Field
[0001] This utility model relates to the field of common tools and equipment, specifically to a tooling for replacing and disassembling a warm forging hammer. Background Technology
[0002] In the forging process, the hammerhead, as the core impact component, must withstand high-frequency, high-intensity impact loads to complete the plastic deformation of the metal. However, long-term impact causes work hardening at the contact surface between the hammerhead and the base, and the gap between the mating surfaces gradually disappears due to oxide layer accumulation and metal creep, forming an interference fit. In addition, the hammerhead is relatively heavy (usually exceeding 50kg), while the internal space of the forging equipment is small. It is difficult to use large tools (such as hydraulic jacks) to disassemble it in a confined space, and the uneven force on the hammerhead makes it prone to slippage, threatening operational safety. If manual hammering or prying is relied upon, it can take 1-2 hours, and forced disassembly can easily damage the threads or mating surfaces, increasing equipment maintenance costs. Utility Model Content
[0003] To solve the above technical problems, this utility model provides a warm forging hammerhead replacement and disassembly fixture that can improve the efficiency of replacement and disassembly. The technical solution is as follows:
[0004] A key feature of a warm forging hammer replacement and disassembly fixture is its U-shaped, open-front clamping section. The inner walls of the clamping section are pre-tightening surfaces. A handle, a hollow cylindrical structure, is connected to the end of the clamping section away from the opening. A movable pre-tightening pin is housed within the handle. A control element, controlling the forward or backward movement of the movable pre-tightening pin, is located at the end away from the clamping section. One end of the movable pre-tightening pin can extend into the clamping section under the action of the control element. With this structure, the hammer assembly to be disassembled can be placed within the pre-tightening surfaces of the clamping section. The control element pushes the movable pre-tightening pin on the inside of the handle towards the clamping section, extending into the pre-tightening surfaces and pressing against the hammer assembly, thus securing the hammer assembly. Utilizing leverage to move the handle allows for rapid disassembly of the hammer assembly, improving disassembly or replacement efficiency.
[0005] Preferably, the control component includes a columnar connecting portion and a disc-shaped handwheel connected to the rear end of the connecting portion. The front end of the connecting portion extends into the handgrip and is connected to the movable preload pin. With this structure, the control component is connected to the movable preload pin, enabling control of the movable preload pin within the handgrip, allowing it to move forward or backward along with the control component.
[0006] Preferably, the outer wall of the connecting part is provided with an external thread structure, and a locking nut is fixed at the end of the handle part away from the clamping part. The locking nut has an internal thread on its inner side, and its connecting part is threadedly connected to the locking nut. With the above structure, the control component is threadedly connected to the locking nut, and it is not easy to fall off when the hammer assembly is fixed by the movable preload pin, so that the movable preload pin can always be kept in contact with the hammer assembly.
[0007] Preferably, a through hole is provided on the side wall of the clamping part away from the opening end, through which the handle part can pass and connect to the clamping part. With the above structure, the through hole further achieves a firm connection between the handle part and the clamping part, and the through hole allows the movable preload pin to pass through and be fixed to the hammer head assembly.
[0008] Preferably, the front end of each clamping part is bent downward to form a positioning hook. With this structure, the positioning hook can quickly engage with the end face of the hammer base groove.
[0009] Preferably, the positioning hook and the clamping part are integrally formed. This integrated design facilitates manufacturing.
[0010] Preferably, a reinforcing plate is provided at the rear of the clamping part above the through hole. With this structure, the reinforcing plate enhances the overall rigidity of the clamping part, preventing deformation during use.
[0011] Compared with the prior art, the advantages of this utility model are: simple structure and easy to use. This simple disassembly tool can quickly and easily disassemble the hammer head assembly by using the lever principle, effectively improving disassembly efficiency and saving time and effort. The disassembly tool is small in size and can be used in narrow spaces. The hammer head assembly is clamped and fixed by the cooperation of the movable pre-tightening pin and the clamping part, which prevents the hammer head assembly from slipping during disassembly and ensures the safety of the user.

[0013] Figure 2 This is a schematic diagram illustrating the use of this utility model. Detailed Implementation
[0014] The present invention will be further described below with reference to the embodiments and accompanying drawings.
[0015] like Figure 1 and Figure 2As shown, a tooling for replacing and disassembling a warm forging hammer includes a clamping part 1 with an open front end and a "U"-shaped structure. The inner walls of the clamping part 1 are all pre-tightening surfaces. A hand-held part 2 is connected to the end of the clamping part 1 away from the opening. The hand-held part 2 is a hollow cylindrical structure. A movable pre-tightening pin 3 is provided inside the hand-held part 2. A control element 5 is provided at the end away from the clamping part 1 to control the movable pre-tightening pin 3 to move forward or backward. One end of the movable pre-tightening pin 3 can extend into the clamping part 1 under the action of the control element 5.
[0016] The control component 5 includes a columnar connecting part 51 and a disc-shaped handwheel 52 connected to the rear end of the connecting part 51. The front end of the connecting part 51 extends into the handheld part 2 and is connected to the movable preload pin 3. The outer wall of the connecting part 51 is provided with an external thread structure. A locking nut 7 is fixed at the end of the handheld part 2 away from the clamping part 1. The locking nut 7 has an internal thread on its inner side, and its connecting part is threadedly connected to the locking nut 7. As the control component 5 is tightened with the locking nut 7, it can push the movable preload pin 3 connected to it in the handheld part 2 to move towards one end of the clamping part 1, extend into the preload surface, and abut against the hammer assembly in the preload surface. Since the control component 5 and the locking nut 7 are threadedly engaged, it can ensure that the movable preload pin 3 does not easily slip, thereby ensuring that the movable preload pin 3 and the hammer assembly are always in abutting state, avoiding the hammer assembly from slipping off during disassembly, ensuring the safety of the user and the reliability of disassembly.
[0017] A through hole is provided on the side wall of the clamping part 1 away from the opening end. The hand-held part 2 can pass through the through hole and connect with the clamping part 1 to ensure the firmness of the connection and prevent the two from falling off during use. The movable pre-tightening pin 3 can pass through the through hole and extend into the pre-tightening surface.
[0018] The front end of each clamping part 1 is bent downward to form a positioning hook 4. The positioning hook 4 and the clamping part 1 are integrally formed. The positioning hook 4 can be quickly locked onto the end face of the hammer forging base groove to achieve connection. A reinforcing plate 6 is provided above the through hole at the rear of the clamping part 1. The reinforcing plate 6 can distribute the force and avoid deformation.
[0019] The working principle of this utility model is as follows: The hammer head assembly is set on the forging equipment. The fixing bolts of the hammer head assembly on the forging equipment are removed. The positioning hook 4 of the replacement and disassembly tool is used to quickly lock onto the end face of the hammer head base groove. Then, the control part 5, which is threadedly connected to the hand-held part 2, is turned, thereby pushing the movable pre-tightening pin 3 in the hand-held part 2 to move towards one end of the clamping part 1 and pass through the through hole, so that the movable pre-tightening pin 3 can fit against the end face of the hammer head and achieve the clamping of the hammer head assembly. With the positioning hook 4 locked at the end face of the hammer head base groove as the fulcrum and the hand-held part 2 as the lever arm, the hammer head assembly can be disassembled from the forging equipment by moving the hand-held part 2 using the lever principle. This saves time and effort and can effectively improve the disassembly efficiency.
[0020] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model. Those skilled in the art, under the guidance of the present utility model, can make various similar representations without departing from the spirit and claims of the present utility model, and such modifications all fall within the protection scope of the present utility model.
