Description

Technical Field

[0001] This utility model relates to the field of cold heading machine processing and manufacturing, specifically to a cold heading machine feeding device. Background Technology

[0002] Cold heading machines are specialized equipment used for the mass production of fasteners such as rivets and bolts, primarily through upsetting. Based on the theory of plastic deformation in metals, a certain pressure is applied to a metal blank at room temperature, causing it to undergo plastic deformation within a die cavity, shaping it into a specified form and size. For metal blanks of fasteners such as rivets and bolts, slender rod-shaped metal is typically conveyed by a feeding mechanism to a cutting mechanism to be cut into small segments, which are then upset. Existing feeding mechanisms are quite complex. For example, the double-heading cold heading machine feeding mechanism disclosed in patent CN105598352A uses a ratchet, gear pair, and feeding shaft for feeding transmission, and a brake wheel and brake spring for stopping feeding. The entire processing is complex, resulting in a high failure rate and significant costs for both manufacturers and users. Utility Model Content

[0006] Preferably, the gear set includes two adapter gears symmetrically arranged on both sides of the intermediate wheel, each adapter gear is driven by an output gear, and each output gear is coaxially connected to a pressure wheel.

[0007] Preferably, the cold heading machine feeding device further includes a transmission housing, and the pressing wheel and gear set are respectively disposed on opposite sides of the transmission housing.

Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0021] like Figure 1-3As shown, this utility model discloses a feeding device for a cold heading machine. This device replaces some processed parts in the prior art with purchased finished parts, shortening the processing cycle, reducing production costs, and improving production efficiency. Specifically, it includes... Figure 3 The pneumatic clutch 1, transmission sleeve 2, and overrunning clutch 3 are connected sequentially from left to right. The left end of transmission sleeve 2 is connected to the actuating part of the right end of pneumatic clutch 1 by screws, and the right end of transmission sleeve 2 is connected to overrunning clutch 3 by key. A drive shaft 4 is connected to the center of the drive part at the left end of the pneumatic clutch by key. The drive shaft 4 extends to the right through transmission sleeve 2 and overrunning clutch 3 and then into transmission housing 9, where it is rotatably connected. A bearing is provided between transmission sleeve 2 and drive shaft 4, allowing drive shaft 4 to rotate freely within transmission sleeve 2. There is a clearance fit between overrunning clutch 3 and drive shaft 4, allowing drive shaft 4 to rotate freely within overrunning clutch 3 as well. On the portion of drive shaft 4 located between overrunning clutch 3 and transmission housing 9, a transmission sleeve swing arm 10 and a drive wheel 8 are connected sequentially from left to right. The swing arm 10 is rotatably connected to drive shaft 4 via bearings, and drive wheel 8 is detachably fixed to drive shaft 4.

[0022] A gear set 5 is mounted on one side of the transmission housing 9 where the intermediate wheel 8 is located, and a pressing wheel 7 is mounted on the other side of the transmission housing 9 opposite to the intermediate wheel 8. There are two sets of pressing wheels 7, symmetrically arranged on both sides of the intermediate wheel 8. Specifically, two gear shafts 6 are installed inside the transmission housing 9, with both ends of the gear shafts 6 protruding from opposite sides of the transmission housing 9. The gear set 5 is mounted on the end of the gear shaft 6 located on the side of the intermediate wheel 8, and the pressing wheel 7 is mounted on the end of the gear shaft 6 located on the other side. The gear set 5 includes two adapter gears symmetrically arranged on both sides of the intermediate wheel. Each adapter gear is driven by an output gear, and each output gear is coaxially connected to a pressing wheel 7.

[0023] When the left and right ends of the pneumatic clutch 1 are not engaged, the swing arm 10 drives the overrunning clutch 3 and the transmission sleeve 2 to rotate freely, and the material remains stationary. When the left and right ends of the pneumatic clutch 1 are engaged, the swing arm 10 drives the overrunning clutch 3 and the transmission sleeve 2 to rotate, the transmission sleeve 2 drives the pneumatic clutch 1 to rotate, the pneumatic clutch 1 drives the intermediate wheel shaft 4, the intermediate wheel shaft 4 drives the intermediate wheel 8, the intermediate wheel 8 drives the gear set 5 to move, and the gear set transmits power to the pressure wheel 7 through the gear shaft. The pressure wheel 7 rotates, causing the material to move. Based on the above process, the purpose of changing the material's motion by opening and closing the pneumatic clutch 1 is achieved. The pneumatic clutch offers advantages such as faster response speed, greater torque, longer service life of the friction plates, lower energy consumption, and higher heat dissipation capacity, thus improving production efficiency and ensuring product quality. This achieves the energy-saving and high-efficiency production requirements.

[0024] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
