Description

Technical Field

[0001] The invention relates to the technical field of rivet processing, and in particular to a rivet and a processing device and a processing method thereof. Background Art

[0002] Rivet processing equipment is a kind of mechanical equipment used to manufacture and process rivets. It is usually used in the field of metal processing, especially in the aviation, automobile, shipbuilding and other industries. It processes the raw materials of rivets (such as steel, aluminum, etc.) into the required shape and specifications through various mechanical processing methods (such as stamping, riveting, cooling, etc.).

[0003] In the prior art, the rivet is sent to the thread rolling area, that is, between the dynamic plate and the static plate, through a loading plate. At this time, the dynamic plate will perform reciprocating linear motion driven by a driving device. Since the thread rolling surface of the thread rolling plate has the same shape as the thread shape required for the rivet, when the rivet enters between the dynamic plate and the static plate, the dynamic plate will move, causing the surface metal of the rivet to undergo plastic deformation under the action of pressure and friction, thereby rolling out a corresponding thread shape on the rivet rod.

[0004] The shortcomings of the above-mentioned prior art solutions are: due to the long-term vibration of the machine, the device will loosen at the connection with the oil supply system pipeline, which will cause insufficient supply of lubricating oil. When the lubricating oil is insufficiently supplied, the dry friction between the rivet and the rolling plate will increase. This unstable friction force will make the rivet prone to up and down displacement during the rolling process, and then the rolling tool will be subjected to uneven load, resulting in uneven wear of the tool. In the long run, it will accelerate the damage of the tool, increase production costs, and affect processing accuracy. In addition, the added downward limit mechanism cannot adapt to rivet heads of different shapes when limiting the rivet. This will cause the operator to spend extra time adjusting the device to adapt to the shape of the rivet head when processing rivets of different shapes, which will increase production preparation time and reduce production efficiency. Based on this, the present invention designs a rivet and its processing equipment and processing method to solve the above problems. Summary of the invention

[0013] Furthermore, the main body of the static structure plate (24) adopts a regular rectangular structure, and the portion of the working surface of the static structure plate (24) other than the first processing area (241) and the second processing area (242) is arranged in a smooth surface.

[0014] In order to better achieve the purpose of the present invention, the present invention also provides a rivet processing method, comprising the following steps: Main body forming: using the die of a cold heading machine to apply pressure to the metal wire at room temperature, so that the wire undergoes plastic deformation to form the basic shape of the rivet main body (5); Groove processing: groove processing is performed on the rivet rod (52) of the rivet body (5) using rivet processing equipment. Specifically, the blanks are transferred one by one in the same posture between the static structure plate (24) and the dynamic structure plate (26) through the loading plate (22), and the power source (21) is started to drive the dynamic structure plate (26) to reciprocate along the length direction of the guide frame (25), and the rivet body (5) is driven by the dynamic structure plate (26) to roll between the static structure plate (24) and the dynamic structure plate (26); during the rolling process, the rivet rod (52) passes through the primary rolling groove (243), the secondary rolling groove (244) and the tertiary rolling groove (245) in sequence, and the three-sided groove (53) is gradually deepened and formed under the cooperation of the three; Surface treatment: pickling is used to remove pollutants on the surface of the rivet body (5), and after pickling, the rivet body (5) is rinsed with clean water to remove residual acid.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. During the rolling process of the rivet body (5), the rivet rod (52) passes through the primary rolling groove (243), the secondary rolling groove (244) and the tertiary rolling groove (245) in sequence, and gradually deepens and forms a triangular groove (53) under the cooperation of the three. In addition, during the forming process of the triangular groove (53), the anti-slip teeth (246) can be tightly engaged with the rivet rod (52), and at the same time, the downward pressure limiting mechanism (3) can limit the rivet body (5), thereby avoiding the cleaning of the rivet body (5) from moving up and down during the rolling process, thereby effectively reducing the possibility of the rivet rod (52) slipping and dislocation between the static structure plate (24) and the dynamic structure plate (26), reducing the number of times of mold maintenance and replacement, reducing production costs, and improving production accuracy.

[0017] 2. In the present invention, after the rivet body (5) enters between the static structure plate (24) and the dynamic structure plate (26), the bottom of the transfer belt (39) is in contact with the top of the rivet body (5). The dynamic structure plate (26) drives the transmission rack (38) to move synchronously during the movement. The transmission rack (38) drives the rotating rod (36) to rotate through the transmission gear (37), thereby causing the transfer belt (39) to move synchronously, thereby reducing the relative movement of the top of the rivet body (5) and the transfer belt (39) during the rolling process, thereby avoiding damage to the transfer belt (39) due to friction between the rivet body (5) and the transfer belt (39). At the same time, the transfer belt (39) and the rivet cap (51) are abutted against each other to achieve upper and lower limit of the rivet body (5), thereby reducing the possibility of the rivet body (5) being displaced up and down during the thread rolling process, thereby reducing the wear of the rivet body (5) and the thread rolling mold, thereby reducing the number of times the thread rolling mold is repaired and replaced, and effectively reducing the production cost.

[0018] 3. After the rivet body (5) is transferred to the feeding end of the static structure plate (24) and the dynamic structure plate (26), the rivet body (5) rolls downward along the inclined surface of the static structure plate (24) to the U-shaped material receiving area at the lower end of the transfer belt (39) and is blocked by the block (47). Then, the micro push rod (42) is started to drive the driving block (43) to move downward. The driving block (43) drives the driven side sliders (44) on both sides to move toward each other through the inclined block structure until the side limit blocks (48) on both sides abut against the rivet cap (51). At this time, the capsule (49) also surrounds the top of the rivet cap (51), and the block (47) and the side limit blocks (48) are closed. The block (48) and the capsule (49) cooperate to achieve a limiting effect on the rivet body (5). The non-Newtonian fluid in the capsule (49) can adapt to different types of rivet caps (51), thereby eliminating the need to frequently replace or adjust equipment, simplifying the operation process, and thus improving the efficiency of the thread rolling process on the rivet body (5), reducing the difficulty of operation and the defective rate. At the same time, the side limiting block (48) is blocked by the rivet cap (51) to limit the vertical displacement distance of the driving pressure block (43), ensuring that the rivet cap (51) can be wrapped by the capsule (49) and avoiding excessive downward pressure of the non-Newtonian fluid in the capsule (49).
