Description

Technical Field

[0001] The present application relates to the technical field of flange forging equipment, and in particular to an electro-hydraulic hammer for flange forging. Background Art

[0002] Flanges are indispensable connecting elements in pipeline systems, and their manufacturing quality has a decisive impact on the overall safety and stability of the system. In the manufacturing process of flanges, forging is particularly critical. However, the traditional forging method relies on manual operation in the flange flipping step, which not only consumes a lot of physical effort for the operator and has low production efficiency, but also often threatens the operator's safety due to the complexity of the operating environment.

[0003] In modern industrial production, although automation technology has been applied in many fields, the degree of automation in the flange forging flipping process is still low. Although some forging equipment has appeared on the market, a lot of manual assistance or forklift participation is still required in the flange flipping process, and true full-automatic production has not been achieved. This not only affects production efficiency, but also increases production costs and safety hazards.

[0004] In summary, the existing flange forging equipment, especially the flipping step, still requires a lot of manual participation, and also has low automation and safety issues. Summary of the invention

[0005] In order to improve the problems of low automation and insufficient safety in the flipping step of existing flange forging equipment, the present application provides an electro-hydraulic hammer for flange forging.

[0006] The present application provides an electro-hydraulic hammer for flange forging, which adopts the following technical solution:

[0007] An electro-hydraulic hammer for flange forging, comprising:

[0008] An electro-hydraulic hammer assembly, the electro-hydraulic hammer assembly comprising a frame, a hammer arm, a hammer head and a base;

[0009] A clamp assembly, the clamp assembly is used to clamp the flange to be turned over;

[0010] A flip assembly, the flip assembly comprises a positioning block, a steering block, a collision rod, a support rod and a collision roller; the positioning block can move up and down in the vertical direction; the longitudinal section of the steering block is an isosceles triangle, the steering block takes a corner away from its hypotenuse as the rotation center, and is rotatably connected to one end of the positioning block, and the other two corners of the steering block away from its rotation center are fixedly connected with a horizontally arranged collision roller; the collision roller is located on the side of the steering block away from the positioning block; the support rod is vertically arranged; the collision rod is horizontally arranged and fixedly connected to the top end of the support rod; the clamp assembly is fixedly connected to the steering block;

[0011] A driving assembly, the driving assembly is used to drive the positioning block to move up and down in the vertical direction;

[0012] When the steering block is located below the collision rod and the positioning block drives the steering block to move upward, the collision roller can collide with the collision rod to drive the steering block to flip, thereby driving the clamp assembly to flip.

[0013] By adopting the above technical solution, the flange can be placed on the base for forging. When one side needs to be flipped after forging, the flange can be clamped by the clamp assembly, and then the positioning block is driven upward by the driving assembly, and the rotating block is driven upward until the collision roller collides with the collision rod, driving the clamp assembly to flip, thereby driving the flange to flip, and then the positioning block is driven downward by the driving assembly, and the flange is placed back on the base to achieve the purpose of flipping the flange. This method of flipping the flange does not require manual operation, improves the degree of automation, and reduces safety risks; through the setting of the frame and the hammer arm, structural support can be provided for the hammer head; The setting of the hammer head can forge the flange; the setting of the base can place the flange to be forged on the base; the setting of the positioning block can set a steering block on the positioning block; by rotatably connecting the steering block with the positioning block, setting a collision roller on the steering block, sliding the positioning block in the vertical direction and setting a collision rod on the top of the support rod, the following effects can be achieved: when the steering block is located below the collision rod, the upward movement of the positioning block can drive the steering block to move upward, thereby driving the collision roller to collide with the collision rod to achieve the flipping of the steering block; by fixedly connecting the clamp assembly with the steering block, the clamp assembly can be driven to flip when the steering block flips.

[0014] Optionally, it also includes a sliding assembly; there are two support rods, and the two support rods are symmetrically distributed with each other, and there are correspondingly two collision rods, which are also symmetrically distributed with each other; the two support rods are both arranged on the sliding assembly; the sliding assembly is used to drive the support rods to slide in the horizontal direction.

[0015] By adopting the above technical solution, when flipping is not required, the steering block is located under one of the collision rods; when flipping is required, the driving assembly is started to drive the positioning block to move upward, and the steering block is driven to move upward until the collision roller collides with one of the collision rods, and the collision roller drives the steering block to flip, and drives the clamp assembly to flip. After the steering block flips, the steering block moves downward, and the supporting rod is moved in the horizontal direction through the sliding assembly, so that the steering block is located under the other collision rod, waiting for the next flipping; when there is only one collision rod, after flipping once, it is necessary to manually rotate the steering block to the bottom of the collision rod before the next flipping can be performed. By adopting the design of two collision rods, there is no need to manually move the steering block to the bottom of the collision rod after flipping once, and the steering block can be directly moved to the bottom of the other collision rod through the sliding assembly, which further improves the degree of automation, saves manpower, and reduces safety risks.

[0016] Optionally, the sliding assembly includes a base and a first slider; the base is horizontally arranged and has a rectangular cross-section; a first slide groove is provided on the base, and the length direction of the first slide groove is the same as the length direction of the base; the size of the first slider is matched with the size of the first slide groove, and the first slider is slidably arranged in the first slide groove along the length direction of the first slide groove; the bottom end of the support rod is fixedly connected to the top surface of the first slider.

[0017] By adopting the above technical solution, the first slider can slide in the base, thereby driving the support rod to slide together, which is convenient for the two support rods to move. When the steering block flips over and moves downward, the upward collision roller of the steering block cannot collide with the collision rod. By sliding the first slider to drive the support rod to slide, the other support rod is aligned with the steering block, so that when the steering block moves upward, the collision roller can collide with the other support rod to form a flip.

[0018] Optionally, it also includes a guide block, which is fixedly arranged on the top surface of the first slider and located between the two support rods; the longitudinal section of the guide block is triangular, and when the steering block moves downward, the steering block can abut against the side surface of one side of the guide block, so that the guide block can drive the first slider to slide in the first slide groove, thereby driving the support rod to move.

[0019] By adopting the above technical solution, when the steering block completes the flipping and downward movement, it can abut against the guide block, thereby driving the guide block to move in the horizontal direction, thereby driving the first slider and the support rod to move together, so that the steering block is aligned with the other support rod in the vertical direction, and there is no need to manually align the support rod with the steering block, which further improves the convenience of operation.

[0020] Optionally, the driving assembly includes a first hydraulic cylinder, which is a multi-stage hydraulic cylinder. The first hydraulic cylinder is vertically arranged, and the piston rod is located above the fixed end, and the top end of the piston rod of the first hydraulic cylinder is fixedly connected to the positioning block.

[0021] By adopting the above technical solution, the first hydraulic cylinder can provide a power source for the positioning block to move in the vertical direction, thereby driving the steering block to move in the vertical direction.

[0022] Optionally, the driving assembly also includes a limit column and a second slider, the limit column is vertically arranged on one side of the first hydraulic cylinder, a second slide groove is provided on the side of the limit column close to the first hydraulic cylinder, the length direction of the second slide groove is the vertical direction, the size of the second slider is matched with the size of the second slide groove, the second slider is slidably arranged in the second slide groove along the vertical direction, and the second slider is fixedly connected to the positioning block on the side away from the limit column.

[0023] By adopting the above technical solution, the moving direction of the positioning block can be limited so that the moving direction of the positioning block is parallel to the moving direction of the second sliding block, thereby improving the stability of the overall device; when the first hydraulic cylinder drives the positioning block to move in the vertical direction, the positioning block can also drive the second sliding block to move in the vertical direction in the second sliding groove.

[0024] Optionally, the cross section of the second slide groove is T-shaped, and the cross section of the second slider is also T-shaped, and when the second slider moves in the second slide groove along the vertical direction, it cannot fall off from the second slide groove.

[0025] By adopting the above technical solution, the second slider can be limited in the second slide groove, so that when the second slider moves in the second slide groove along the vertical direction, it cannot fall off from the second slide groove, further enhancing the overall stability of the device.

[0026] Optionally, the positioning block is a hollow structure, and a steering rod fixedly connected to the steering block is rotatably arranged inside the positioning block, the end face of the steering rod away from the steering block is fixedly connected to a first limiting rod, and the bottom surface of the positioning block is fixedly connected to a vertically arranged second limiting rod on a side away from the steering block, the end of the first limiting rod away from the steering rod is rotatably connected to an elastic rope, and the end of the elastic rope away from the first limiting rod is rotatably connected to the bottom end of the second limiting rod; when the elastic rope is in a balanced state, the first limiting rod is in a horizontal state, and the hypotenuse of the steering block is in a vertical state.

[0027] By adopting the above technical solution, when the clamp does not need to be flipped, the elastic rope is in a balanced state, the first limit rod is in a horizontal state, and the hypotenuse of the steering block is in a vertical state. At this time, the balance of the clamp can be maintained by the elastic force of the elastic rope; when the clamp flips, the collision roller collides with the collision rod, driving the steering block to flip, driving the steering rod to flip, driving the first limit rod to rotate, and driving the elastic rope to stretch. When the steering block flips ninety degrees, the first limit rod is in a vertical state, and the elastic rope stretches to its longest state. When the steering block continues to flip from ninety degrees to one hundred and eighty degrees, the elastic rope contracts, and the contraction force of the elastic rope can also assist in driving the steering block to continue to flip, so that the steering block can complete a rotation of one hundred and eighty degrees, thereby improving the efficiency of the steering block from rotating ninety degrees to one hundred and eighty degrees, and facilitating the steering block to rotate to the next balanced state; through the arrangement of the first limit rod, the second limit rod and the elastic rope, the overall stability, balance and working efficiency of the device can be further improved.
