[0002] The electro-hydraulic hammer is a new type of forging equipment, which is mainly installed at the output end of the forging machine to facilitate the forging of the blank and improve the quality of the flat forging. The guide of the electro-hydraulic hammer is an "X" guide rail, which can greatly improve the guide accuracy of the electro-hydraulic hammer. The electro-hydraulic hammer has a large workload, and it may be deformed or damaged after a period of use. The hammer head needs to be replaced. Due to the large weight of the hammer head and the need to transport the hammer head to the forging machine, it is not possible to use a truss to lift it in one step. It is necessary to use an auxiliary tooling to transport the hammer head to a designated position in the forging machine, or to transport the disassembled hammer head out. When the existing electro-hydraulic hammer head replacement auxiliary tooling is in use, the movable support frame is provided with an external extension part and the external extension part is extended into the forging machine, so that the movable bearing part on the support frame can be used to transport the hammer head to the forging machine through the external extension part of the support frame. However, since the device pushes the hammer head to the outward extension part on it when pushing the hammer head, it is easy to cause the center of gravity to be unstable and overturned, and the operation process is relatively cumbersome.

[0003] The existing patent application number: 202121753877.X discloses a hammer head auxiliary installation device for electro-hydraulic hammer production. The device can carry and adjust the position of the hammer head through the cooperation of the limit assembly and the adjustment assembly on the support frame, so as to transport the hammer head to the installation position in the forging machine. In the above-mentioned prior art, when the device is in use, the placement groove needs to be driven to the outside of the support surface of the support frame before the hammer head can be transported to the installation position, and the above-mentioned technical problems still exist. Utility Model Content

[0004] The utility model aims to provide an auxiliary tool for replacing the hammer head of an electro-hydraulic hammer, so as to solve the problems in the above-mentioned background technology that the hammer head is prone to overturning due to unstable center of gravity and the operation process is relatively complicated.

[0034] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0035] like Figures 1 to 5 As shown, an auxiliary tool for replacing the hammer head of an electro-hydraulic hammer comprises a forging table 1, and the auxiliary tool for replacing the hammer head of the electro-hydraulic hammer further comprises:

[0036] Two movable guide parts 3 are respectively slidably connected to two groups of guide grooves 2 arranged on the forging table 1, the two groups of guide grooves 2 are relatively distributed on the forging table 1, and two guide grooves 2 form a group, and the two guide grooves 2 in one group are respectively located on both sides of the forging table 1.

[0037] A bearing portion 4 for carrying a hammer is disposed between the two movable guide portions 3 .

[0038] A positioning portion 5 is provided between the movable guide portion 3 and the guide groove 2 and is used to fix the movable guide portion 3 .

[0039] The mobile guide part 3 comprises:

[0040] Two sliding blocks 31 are slidably disposed in the two guide grooves 2 respectively.

[0041] A support column 32 is fixed on the slider 31 .

[0042] The support slide rail 33 is fixed between the two support columns 32 . The support slide rail 33 and the support columns 32 together form a U-shape, and the support slide rail 33 is located above the forging table 1 .

[0043] The extension rail 34 is hinged to one end of the support rail 33 , and a rail groove 37 is provided on both the support rail 33 and the extension rail 34 .

[0044] A support leg 36 is hinged to a receiving slot 35 provided at the bottom of the extension slide rail 34 .

[0045] When the hammer head of the electro-hydraulic hammer needs to be disassembled and replaced, the two supporting slide rails 33 are first moved closer to each other until the two supporting slide rails 33 are located at the opposite ends of the two sets of guide grooves 2, and then the extension slide rail 34 is laterally moved to deflect it 180°. At this time, it is in a colinear relationship with the supporting slide rail 33, and the opposite surfaces of the two are in conflict with each other. The free end of the supporting leg 36 can automatically droop and deflect downward under the action of gravity, and contact the ground, which can preliminarily complete the deployment and erection of the movable guide part 3, and make it directly below the hammer head of the electro-hydraulic hammer to facilitate the subsequent support of the hammer head.

[0046] In this embodiment, the storage groove 35 matches the support leg 36, and the storage groove 35 is located at the bottom of the free end of the extension slide rail 34. With such a design, when the extension slide rail 34 is deflected and unfolded, the free end of the support leg 36 can automatically droop and deflect downward and touch the ground under the action of gravity until the two are parallel in their length direction, so as to support the free end of the extension slide rail 34. Before the extension slide rail 34 is deflected and stored, the support leg 36 is first stored in the storage groove 35, and then the extension slide rail 34 and the support slide rail 33 are folded in half at the hinge between the two and stored until the two are parallel in their width direction, and then the support slide rail 33 is pushed to the boundary of the forging table 1 to keep it away from directly below the hammer head to avoid affecting the forging operation of the forging.

[0047] In this embodiment, the track grooves 37 are relatively distributed on the opposite surfaces of the two supporting slide rails 33, and the two adjacent track grooves 37 correspond to each other. Here, the two adjacent track grooves 37 refer to the track grooves 37 on the connected supporting slide rails 33 and the extension slide rail 34. When the two are unfolded and arranged side by side in their length direction, the two adjacent track grooves 37 are also arranged side by side in their length direction, and the opposite ends of the two adjacent track grooves 37 are butt-connected.

[0048] In this embodiment, the bearing portion 4 includes:

[0049] A supporting plate 41 is provided on the top of the supporting slide rail 33 .

[0050] The slide bar 42 is slidably disposed in the track groove 37 relative to the slide bar 42 fixed to the bottom of the supporting plate 41 .

[0051] The roller 44 is rotatably connected to the wheel groove 43 provided at the bottom of the slide bar 42 , and the bottom of the roller 44 abuts against the bottom of the inner wall of the track groove 37 .

[0052] The reinforcing rib 45 is fixed between the two slide bars 42 , and the top of the reinforcing rib 45 is fixed to the bottom of the supporting plate 41 . The reinforcing rib 45 is used to enhance the bearing strength of the supporting plate 41 .

[0053] After the two movable guide parts 3 move to under the hammer head, the bearing part 4 is placed between the two movable guide parts 3, and the slide bar 42 is placed in the track groove 37, and then the supporting plate 41 is pushed to just under the hammer head. By setting the roller 44, the moving resistance of the supporting plate 41 when carrying the hammer head is reduced, which makes it easy to transport the old hammer head from the forging table 1, and then transport the new hammer head to the forging table 1, which facilitates the replacement operation of the hammer head and can also improve the stability of the hammer head when it is carried.

[0054] In this embodiment, the positioning portion 5 includes a positioning bolt 52 threadedly connected to a screw hole 51 laterally arranged on one of the sliders 31, one end of the positioning bolt 52 passes through the slider 31 and extends into the guide groove 2, and one end of the positioning bolt 52 is plugged into a limiting hole 53 arranged in the guide groove 2. There are two limiting holes 53 and they are located at both ends of the guide groove 2, so that the supporting slide rail 33 can be fixed directly under the hammer head when the hammer head is replaced and transported, so as to avoid displacement of the supporting slide rail 33 during transportation of the hammer head, thereby improving the stability of the transportation of the hammer head. After the replacement of the hammer head is completed, the bearing portion 4 can be removed and erected against the outside of the forging machine, and then the supporting slide rail 33 can be pushed to the boundary of the forging table 1 away from the middle thereof, and then the positioning bolt 52 can be screwed so that one end of the supporting slide rail 33 is inserted into the limiting hole 53 in the guide groove 2 near the boundary of the forging table 1, so as to fix the supporting slide rail 33 away from the forging area of ​​the hammer head and avoid interfering with the forging operation of the forging.

[0055] The above description is only the preferred embodiment of the utility model, and the parts not described in the utility model can be implemented by adopting or drawing on existing technologies. Of course, the above description is not a limitation of the utility model, and the utility model is not limited to the above examples. The changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the utility model should also fall within the protection scope of the utility model.
