[0001] The utility model relates to the technical field of forging equipment, in particular to a flange forging loading and unloading machine. Background Technique

[0002] A forging loading and unloading machine is a device for loading and unloading workpieces during forging. When loading and unloading flanges, the forging loading machine needs to place a solid cylindrical forging blank onto the forging machine for forging. After forging, a disc-shaped blank will be obtained.

[0003] For example, in the "A Flange Forging Loading and Unloading Machine" with the Chinese patent publication number CN211071669U, this utility model belongs to the field of forging equipment, especially a flange forging loading and unloading machine. Aiming at the problem that the chuck of the existing forging loading and unloading machine cannot clamp cylindrical forgings of different sizes, the following scheme is proposed. It includes a movable arm, on one side of the movable arm, a telescopic hydraulic cylinder is fixedly installed. The output end of the telescopic hydraulic cylinder is fixedly installed with a moving shaft. One end of the moving shaft away from the telescopic hydraulic cylinder is fixedly installed with a sliding rod. Two sliders symmetrically arranged based on the moving axis are slidably sleeved on the sliding rod. On the side of the two sliders away from the telescopic hydraulic cylinder, a connecting rod and a push rod are rotatably installed respectively.

In this utility model, when the telescopic hydraulic cylinder is started, the two first clamping plates and the two telescopic clamping plates can approach each other vertically to clamp the cylindrical forging, and it can clamp cylindrical forgings of different sizes, meeting people's usage requirements.

[0004] However, in actual use, it has the problem that its structure is prone to damage. When clamping, the connecting rod and the push rod bear the clamping force. The connecting rod and the push rod are too thin and prone to breakage. After they break, the clamping force on the flange will be lost, and it is not convenient to strengthen the reliability of the equipment by setting a more stable structure. Therefore, a flange forging loading and unloading machine is proposed to solve the above-mentioned problems. Content of the Utility Model

Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-4 , an embodiment of the present utility model is: A flange forging loading and unloading machine includes a movable arm 1, a connecting seat 2 is fixedly connected above the movable arm 1, the shape of the connecting seat 2 is U-shaped, a clamping assembly 3 is arranged above the connecting seat 2, the clamping assembly 3 includes a support sleeve 301, the support sleeve 301 is fixedly connected to the upper part of the connecting seat 2, a sliding bar 302 is slidably connected to the inner surface of the support sleeve 301, a clamping seat 303 is fixedly connected to the left end of the sliding bar 302, a spring 304 is elastically connected between the clamping seat 303 and the support sleeve 301, the spring 304 will apply a pulling force to pull the clamping seat 303 towards the support sleeve 301 in the normal state, a first clamping plate 305 is fixedly connected below the clamping seat 303, an adjusting assembly 4 is arranged above the first clamping plate 305, the number of the clamping assemblies 3 is two groups, the two groups of clamping assemblies 3 are symmetrically arranged on the left and right above the connecting seat 2, a driving assembly 5 is arranged below the clamping assembly 3, the driving assembly 5 includes a first support piece 501, the first support piece 501 is fixedly connected to the back surface of the movable arm 1, a first hydraulic push rod 502 is fixedly connected above the first support piece 501, a pushing block 503 is fixedly connected above the first hydraulic push rod 502, a tightening assembly 6 is arranged above the pushing block 503, the tightening assembly 6 includes a connecting rod 601, the number of the connecting rods 601 is two, the two connecting rods 601 are respectively fixedly connected to the left and right sides of the pushing block 503, a top block 602 is fixedly connected above the connecting rod 601, an inclined surface is arranged downward on the top block 602, and the top block 602 is movably attached to the sliding bar 302.

[0022] Working principle: When in use, the external robotic arm device drives the movable arm 1 to cover the two clamping components 3 over the flange to be clamped. At this time, the first hydraulic push rod 502 is started, and its telescopic movement pulls the pushing block 503 downward. The downward movement of the pushing block 503 drives the connecting rod 601 to pull the top block 602 downward. At this time, the inclined surface on the top block 602 abuts against the sliding bar 302, causing the sliding bar 302 to slide on the inner surface of the support sleeve 301, thereby stretching the spring 304. At this time, the sliding bar 302 drives the clamping seat 303 to clamp the flange to be clamped with the first clamping plate 305, facilitating the taking of materials. When it is necessary to loosen the flange, the first hydraulic push rod 502 drives the pushing block 503 to raise the top block 602. At this time, the spring 304 releases its elastic force to reset the first clamping plate 305, thereby loosening the flange.

[0023] Please refer to Figures 1-4 Based on the above embodiments, in another embodiment of the present utility model, the adjusting component 4 includes a second clamping plate 401. A sliding piece 402 is fixedly connected below the second clamping plate 401. The sliding piece 402 movably penetrates below the clamping seat 303 and the first clamping plate 305. A sliding sleeve 403 is fixedly connected below the sliding piece 402. The number of the second clamping plate 401, the sliding piece 402, and the sliding sleeve 403 is two. A sliding rod 404 is slidably connected to the inner surface of the sliding sleeve 403. The number of the sliding rods 404 is one. A pushing component 7 is arranged below the sliding rod 404. The pushing component 7 includes a second support piece 701. The second support piece 701 is fixedly connected to the front surface of the movable arm 1. A second hydraulic push rod 702 is fixedly connected above the second support piece 701. The upper end of the second hydraulic push rod 702 is fixedly connected to the lower part of the sliding rod 404.

[0024] Working principle: While the clamping seat 303 and the first clamping plate 305 in the two clamping components 3 clamp or loosen the flange, they also drive the sliding piece 402 to move the second clamping plate 401 following the first clamping plate 305. At this time, the sliding sleeve 403 below the sliding piece 402 slides on the outer surface of the sliding rod 404 to achieve a limiting effect. When it is necessary to clamp a flange with a larger size, by starting the second hydraulic push rod 702 to push the sliding rod 404 upward, the sliding sleeve 403 is driven to make the sliding piece 402 extend upward from the clamping seat 303. The sliding piece 402 drives the second clamping plate 401 to rise, thereby increasing the distance between the second clamping plate 401 and the first clamping plate 305, achieving the effect of facilitating the clamping of a flange with a larger size.

[0025] The utility model provides a flange forging loading and unloading machine. There are many methods and ways to specifically implement this technical solution. The above is only the preferred embodiment of the utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the utility model. Each component not clearly defined in this embodiment can be implemented by using the prior art.
