Description

Technical Field

[0001] This invention belongs to the field of forging machine tool technology, specifically referring to a forging machine tool with a protective mechanism. Background Technology

[0002] Forging machine tools are a general term for processing equipment that uses impact or pressure to cause plastic deformation of metal between upper and lower anvils in order to obtain the desired shape, size and performance. They are widely used in many fields such as automobiles, aerospace, and machinery manufacturing, and play a key role in improving the strength and performance of metal parts.

[0003] However, current forging machine tools present numerous safety hazards and environmental pollution problems during actual processing. During forging, the forging is subjected to high-energy impacts, resulting in uneven internal stress distribution, which easily leads to forging fracture. The resulting metal fragments fly at high speeds, posing a serious threat to the personal safety of operators. Simultaneously, the oxide scale on the metal surface detaches during forging, releasing large amounts of oxide dust. This dust permeates the air, polluting the working environment and potentially being inhaled by operators, harming their health. Furthermore, the high temperatures generated during forging raise the surrounding air temperature, forming fumes and further deteriorating the working environment. Moreover, forging machine tools require lubricating oil during operation; the lubricating oil evaporates at high temperatures, producing oil mist and harmful gases, affecting air quality and potentially causing respiratory illnesses and other health problems for operators with prolonged exposure. Summary of the Invention

[0004] To address the aforementioned problems, this invention proposes a forging machine tool with a protective mechanism.

[0012] Furthermore, the telescopic partial protection component includes a storage cavity located at the top interior of the load-bearing base. The lower end of the storage cavity is connected to a pushing cavity. The lower end of the outer wall of the cavity is connected to one end of a second connecting pipe, and the other end of the second connecting pipe is connected to the lower end of the pushing cavity.

[0016] (2) The air curtain protection mechanism is used to block the spread of smoke and heat during the forging of metal billets, as well as the release of oxide scale dust and high-temperature smoke during the forging process. If the lubricating oil evaporates, oil mist and harmful gases will also be generated. The air curtain guides larger debris to fall into the collection tank in a designated direction, while blocking the dust from spreading outward.

[0018] (4) The baffle rises automatically during forging, which can physically block metal slag and sparks, and prevent burns to operators or ignition of combustibles.

[0019] (5) The air curtain + square air inlet slot circulation airflow design guides the oxide scale dust and high temperature smoke to the lower cavity to prevent leakage and improve the air quality in the workshop. Activated carbon can adsorb organic gases (VOCs) and some odors formed by the evaporation of lubricating oil, improve the working environment. The water pool cools and captures the falling high temperature particles to prevent them from bouncing and splashing again, thus improving cleanliness and safety. Attached Figure Description

[0033] Positioning assembly 4 includes a telescopic cylinder 44, a clamping tube 45, a first lead screw 46, a second lead screw 47, a first sleeve 48, a second sleeve 49, a first clamping plate 50, a second clamping plate 51, and a motor 5.

The threads of the first lead screw 46 and the second lead screw 47 are opposite.

[0034] In practical use, during forging, the heated metal billet is placed on the base plate 28 using a fixture. The high-pressure blower 19 is then started. The high-pressure blower 19 draws air from the lower cavity 8 of the machine tool, which then enters the square frame 17 through the connecting hose 21 and the metal connecting pipe 20. Finally, the air is blown through the long air outlet 18 into the square air inlet groove 13 and into the lower cavity 8 of the machine tool, forming a high-speed thin airflow layer around the metal billet. This layer is used to block the diffusion of smoke and heat during forging, as well as the release of oxide scale dust and high-temperature fumes during the forging process. If the lubricating oil evaporates, oil mist and harmful gases will also be generated. An air curtain guides larger debris to fall into a collection tank in a designated direction, while simultaneously preventing dust from spreading outwards. A water tank 22 prevents secondary splashing of high-temperature particles. A magnet 23 is used to attract high-temperature iron filings, and activated carbon 25 is used to absorb organic gases and some odors. The output of a telescopic cylinder 44 moves, driving the clamping tube 45 to move and push the metal billet to the center of the base plate 28. The output of a motor 5 rotates, driving the first lead screw 46 and the second lead screw 47 to rotate. The threads of the first lead screw 46 and the second lead screw 47 are opposite. The first clamping plate 50 and the second clamping plate 51 move towards each other, pushing the metal billet to the center of the base plate 28. Subsequently, the telescopic cylinder 44 resets, and then the hydraulic cylinder 16 is activated. The output end of the hydraulic cylinder 16 moves, causing the hydraulic hammer 15 to move downwards to forge the metal billet. After the hydraulic hammer 15 contacts the metal billet, it continues to move downwards, triggering the component 26 into the groove 30 until the base plate 28 contacts the first limiting plate 31. At this time, the first spring 33 is compressed, and the first piston 34 pushes the hydraulic oil in the cavity 35 into the pushing cavity 43 through the second connecting pipe 41. At this time, the second piston 40 moves upwards, causing the connecting rod 52 to move upwards, and the connecting rod 52 moves upwards, causing the push plate 37 to move upwards. The push plate 37 moves upward, causing the baffle 36 to move upward until the second piston 40 contacts the second limit plate 39. At this time, the second spring 38 is compressed. The baffle 36 is used to block the metal billet from all sides to prevent the metal billet from being hit and generating sparks or metal slag, which could burn the skin or ignite flammable materials. After the forging assembly 9 completes the forging, the output end of the hydraulic cylinder 16 is reset. Then, the second spring 38 pushes the push plate 37 to reset, and the first spring 33 pushes the pressure plate 32 to reset. The base plate 28 rises above the groove 30. This is the overall working process of the present invention. This step can be repeated for the next use.
