Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of metal drawing, in particular to a raw material drawing equipment for automobile spring processing. BACKGROUND

[0002] Automobile spring processing needs to be manufactured by using advanced non-ferrous metal materials, and the metal wire needs to be drawn before spring processing, and the metal wire drawing is a metal plastic processing technology, which uses tension to draw the wire blank from the die hole of the drawing die, thereby generating a small section of metal wire, and this process is widely used in the industrial field, and various different specifications and materials of metal wires such as copper wire, steel wire and nickel wire can be produced.

[0003] In the metal wire drawing process, in order to effectively reduce the frictional resistance and wear between the metal wire and the drawing die, ensure the smoothness of the drawing process and achieve the expected size accuracy and surface quality, the outer surface of the metal wire needs to be fully and uniformly coated with lubricating powder before entering the die, but when the metal wire coated with lubricating powder passes through the drawing die, the lubricating powder is blocked by the die structure or carried out with the metal wire, and a considerable part will be scattered to the surrounding air or deposited in the equipment. At present, a material collecting inclined plate is mainly arranged below the inlet end and the outlet end of the drawing die, which guides and collects the lubricating powder scraped off by the die to a specific position by gravity, and then uses a lifting conveying equipment (such as a screw conveyor) to lift the collected powder to the coating device again to realize recycling. However, the lubricating powder is easily affected by factors such as equipment vibration and air flow disturbance during the falling process, resulting in secondary dusting, which cannot be completely captured by the inclined plate, and the scraping off of the lubricating powder at the die is a relatively slow and non-central burst process accompanied by each drawing action. The accumulation of powder at the collection point needs a long time to reach an amount sufficient to effectively lift, and often needs to rely on manual regular cleaning to collect the scattered powder, which not only increases the labor intensity of workers, but also makes the recycling process discontinuous and inefficient, and increases the labor intensity of workers.

[0014] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, the swing of the arc-shaped push rod in the recovery push assembly is coordinated with the hinge to be transmitted to the connecting rod below, and the connecting rod is connected to the moving block at the bottom. The movement trajectory of the moving block is strictly constrained by the limit plate, so that it can only perform precise reciprocating linear motion along the preset horizontal direction. The arc-shaped push plate is like a "scraper" or "push plate", which is close to the inner wall of the bottom of the recovery cylinder, and continuously and effectively pushes and concentrates the lubricating powder deposited on the arc surface of the bottom of the cylinder to the discharge pipe position. The lubricating powder pushed to the discharge pipe is smoothly introduced into the storage cylinder below through the discharge pipe and the inclined pipe connected thereto under the action of gravity and pushing force, completing a high-efficiency recovery process.

[0015] In the present invention, the arc-shaped pushing plate in the recovery pushing assembly is tightly fitted to the arc surface of the bottom of the recovery cylinder, thereby minimizing residual dead angles and ensuring that the lubricating powder deposited at various places on the bottom of the cylinder can be effectively scraped up and gathered. Compared with relying solely on gravity or airflow, this mechanical active pushing can more reliably concentrate the powder to the designated outlet, significantly improving the recovery efficiency and recovery rate, especially for powders with poor fluidity or easy to compact. The entire pushing and recovery process is carried out in a highly sealed environment, which completely eliminates the environmental pollution problems caused by the dispersion and dust of lubricating powder in traditional open collection or lifting processes, and completely avoids the secondary pollution and manual cleaning burden caused by the scattering of powder inside the equipment, greatly improving the working environment.

[0016] In the application, the whole turnover frame is driven to slide in the horizontal direction in the turnover hole inside the turnover plate from the collection position located directly below the recycling cylinder, and is moved to the unloading preparation position directly above the lubricating cylinder, and the poured lubricating powder falls on the arc-shaped recycling disc, the arc surface design of the recycling disc guides the powder to smoothly slide into the arc-shaped conduit connected therewith, and the lubricating powder is safely and leak-free conveyed back into the lower lubricating cylinder through the arc-shaped conduit under the action of gravity, and is prepared for the next round of coating use, and the application is started only when the collected lubricating powder in the storage cylinder reaches the preset amount, which solves the pain points of the traditional lifting equipment, such as 'empty waiting' or low-efficiency operation, the turnover action can completely empty the storage cylinder, ensures that there is no residue in the cylinder, avoids the residue problem that may exist in the traditional scraper or screw conveyor, and the recycling efficiency of the lubricating powder is high.

[0017] In the application, the storage cylinder of the recycling turnover assembly collects the powder below the recycling cylinder, and the powder is lifted, translated, and unloaded until it is recycled back to the lubricating cylinder through the arc-shaped conduit, and the whole material path is in a highly sealed state, which fundamentally eliminates the risk of powder drifting and dust flying in the recycling, lifting, and transporting processes, completely solves the core problems of dust polluting the environment and endangering the health of workers, and avoids material loss, and through the ingenious 'lifting, translating, and turning' movement chain and the fully-closed material path design, the batch recycling is perfectly realized in a demand-based, efficient, and zero-pollution manner, and the intermittent operation mode significantly reduces the energy consumption, and the rigid and reliable mechanical transmission ensures the stability of the action.

[0018] In the application, when the lubricating powder is pushed to the end of the discharge pipe by the push-pull discharge assembly cooperating with the arc-shaped push plate, the movable rack plate fixed on the side surface of the push plate moves forward and is engaged with the driving gear installed on the top of the discharge pipe, the linear motion of the rack plate drives the driving gear to rotate, and then drives the whole discharge pipe to rotate accurately in the axial direction under the support of the bearing at the bottom of the recycling cylinder, the rotation of the discharge pipe makes the discharge hole of the side wall of the discharge pipe accurately turn to one side of the pushing direction of the arc-shaped push plate, and the lubricating powder is finally injected into the central area of the lower storage cylinder, realizing concentrated and non-spraying directional discharge, and the accumulated lubricating powder in the recycling cylinder cannot contact the discharge hole during the collection process, and in combination with the sealing property of the pipeline itself, the possibility of accidental leakage of the powder from the inclined pipe is completely eliminated.

[0019] In the application, the T-shaped piston plate of the bulk material blowing assembly generates positive pressure inside the air blowing cylinder, the compressed air in the air blowing cylinder enters the return seat through the air outlet pipe, and the air is discharged through the blowing head on the return seat, the blowing head drives the lubricating powder scattered at both ends of the arc-shaped recycling disc into the arc-shaped conduit during the air discharge process, and the lubricating powder is effectively recycled, the lubricating powder cannot be scattered on the arc-shaped recycling disc, the powder moves along the preset track under the traction of the pneumatic force, is accurately introduced into the arc-shaped conduit, the arc-shaped recycling disc does not have lubricating powder residue overflow, and the cleanliness of the processing table is ensured.

The entire metal wire is covered in the lubricating powder, which can realize the overall coverage of the metal wire. The metal wire wrapped with the lubricating powder will be scraped off by the drawing die 11, and the scraped lubricating powder will fall into the bottom of the recycling cylinder 20.
