Description

Technical Field

[0001] The invention relates to the technical field of forging, in particular to a cold forging machine with waste gas treatment function. Background Art

[0002] Cold forging is a processing technology that plastically deforms metal materials at room temperature or near room temperature. It uses a mechanical press or hydraulic press to apply high pressure to the metal blank to deform it and fill the mold cavity to obtain parts of the desired shape and size. Compared with hot forging and warm forging, cold forging technology has higher dimensional accuracy and surface finish, while reducing material waste and processing costs. The cold forging machine is mainly composed of a slide, a ram, a bed, and a forging die. During the working process, the slide moves downward through the drive of the transmission device and the motor, pushing the workpiece material on the workbench into the forging die. The ram squeezes the workpiece, deforming it and filling the mold cavity. The forging die defines the shape and size of the final product.

[0003] During the cold forging process, a certain amount of waste gas will be generated due to the plastic deformation of metal materials and the friction between the die and the workpiece. These waste gases may contain metal particles, lubricating oil vapor and other harmful substances, posing a potential threat to the environment and workers' health. Therefore, it is very important to take effective waste gas treatment measures in cold forging operations. Summary of the invention

[0004] The invention aims to solve the technical problem of how to collect the waste gas generated during the cold forging process, and proposes a cold forging machine with waste gas treatment. The technical solution of the invention is as follows: A cold forging machine with waste gas treatment includes: a machine tool, a cold forging device, a waste gas recovery device, and a feeding device.

The feeding device is arranged above the machine tool, arranged on the side of the waste gas recovery device, fixedly connected to the machine tool, and connected to the waste gas recovery device.

[0005] When the work starts, the staff turns on the cold forging device and the waste gas treatment device. After the staff turns on the cold forging device, the cold forging device forges the workpiece. When the cold forging device forges the workpiece, it will drive the waste gas recovery to form a closed space, thereby preventing the waste gas from leaking out and preventing the residue from splashing during forging and causing harm to the staff. After forging is completed, the cold forging device will drive the waste gas recovery device to open the closed space, and the waste gas recovery device will drive the loading device to load and unload the workpiece, and at the same time, it can also clean the residue on the cold forging device.

[0008] Furthermore, a placement groove is arranged in the middle of the load-bearing platform.

[0009] The placement slot in the middle of the load-bearing platform facilitates the positioning of the workpiece.

When the moving box 402 moves to the right, the fixed block 406 moves to the left relative to the moving box 402, and the fixed block 406 pulls the second connecting rope 410, thereby pulling the sliding block 405 to move to the right relative to the moving box 402, thereby driving the third connecting plate 411 and the placement plate 412 to move to the right relative to the moving box 402, until the placement plate 412 moves above the load-bearing platform 207, and the workpiece on the placement plate 412 falls into the load-bearing platform 207, thereby completing the loading of the workpiece.

[0045] The first connecting rope 409 and the second connecting rope 410 are metal ropes.

[0046] The metal rope has high strength, which prevents the first connecting rope 409 and the second connecting rope 410 from breaking during operation.

[0047] The placement plate 412 has a square opening.

[0048] The square opening on the placement plate 412 is used so that when the placement plate 412 moves to the position just above the load-bearing platform 207 , the workpiece falls into the placement groove.

[0049] The lower surface of the placement plate 412 is provided with cotton cloth.

[0050] The cotton cloth can clean the residue on the top of the load-bearing platform 207 to prevent the workpiece processing from being affected.

[0051] Working principle: At the beginning of the work, the staff opens the first telescopic rod 203, the second telescopic rod 205 and the air purifier 305. When the staff opens the first telescopic rod 203, the first telescopic rod 203 extends, the first telescopic rod 203 extends to drive the first connecting plate 204 to move downward, the first connecting plate 204 moves downward to drive the second telescopic rod 205 to move downward, the second telescopic rod 205 moves downward to drive the stamping plate 206 to move downward until it reaches a certain position, and then the second telescopic rod 205 reciprocates to drive the stamping plate 206 to move up and down to forge the workpiece, and when the forging is completed, the first telescopic rod 203 shortens, the first telescopic rod 203 shortens to drive the first connecting plate 204 to move upward, the first connecting plate 204 moves upward to drive the second telescopic rod 205 to move upward, the second telescopic rod 205 moves upward to drive the stamping plate 206 to move upward until it returns to its original position.

[0052] When the first connecting plate 204 moves downward, the first connecting plate 204 drives the first curved rod 308 to rotate, the first curved rod 308 rotates to drive the second curved rod 309 to rotate, the second curved rod 309 rotates to drive the third curved rod 310 to rotate, and the third curved rod 310 rotates to drive the arc baffle 303 to rotate until the two arc baffles 303 contact to form a closed space. When the two arc baffles 303 rotate, the suction nozzle 304 will be driven to rotate. When the workpiece is forged, the exhaust gas generated will enter the air purifier 305 through the suction nozzle 304 to filter the exhaust gas. At the same time, the arc baffle 303 can prevent the residue from splashing during the forging process and causing harm to the staff. When the first connecting plate 204 moves upward, the first connecting plate 204 drives the first curved rod 308, the second curved rod 309 and the third curved rod 310 to rotate, and the third curved rod 310 rotates to drive the two arc baffles 303 to rotate in the opposite direction until the two arc baffles 303 return to their original positions.

[0053] When the arc baffle 303 rotates in the opposite direction, the arc baffle 303 drives the threaded rod 302 to rotate, and the rotation of the threaded rod 302 drives the second connecting plate 401 to move right, and the second connecting plate 401 moves right and drives the moving box 402 to move right, and the moving box 402 moves right and drives the first pulley 407 and the second pulley 408 to move right, thereby driving the third connecting plate 411 and the placement plate 412 to move right, and the placement plate 412 moves right and drives the workpiece to move right. When the moving box 402 moves to the right, the fixed block 406 moves to the left relative to the moving box 402, and the fixed block 406 pulls the second connecting rope 410, thereby pulling the sliding block 405 to move to the right relative to the moving box 402, thereby driving the third connecting plate 411 and the placing plate 412 to move to the right relative to the moving box 402, until the placing plate 412 moves to the top of the load-bearing platform 207, and the workpiece on the placing plate 412 falls into the load-bearing platform 207, thereby completing the loading of the workpiece. At the same time, the placing plate 412 can clean up the residue above the load-bearing platform 207 to prevent affecting the workpiece processing.

[0054] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
