Description

1 TARIFF INNOVATION IN STROKE ADJUSTMENT STRUCTURE OF PRESS MACHINES TECHNICAL AREA 5 The invention is widely used in metal forming processes in industrial production processes. This relates to the stroke / course change mechanism of the type C eccentric press machines used. Specifically, to make the course / stroke change process faster, easier and safer. It relates to a newly developed mechanism design. 10 STATE OF THE ART Stroke of type C eccentric press machines used in industrial production processes Modification mechanisms often involve complex structures and require various 15 during use. This presents challenges. In current systems, the course / stroke change process is done manually. This is how it is carried out, which leads to longer processing times and decreased production efficiency. This leads to a decrease. Also, in some cases, the mechanism may jam or... Problems such as freezing occur, which increases the response time for operators. This leads to production interruptions. 20 Because the course / stroke change process is manual and complex, the adjustment process takes a long time. This reduces production efficiency. The stroke / course change process is currently in place. Since this is usually done manually in these systems, the operator has to physically adjust the set points. It needs to intervene as follows. This process involves ensuring the crankshaft and its connecting elements are correctly positioned. positioning, loosening and tightening of screws, and precise measurement of stroke / course. It involves adjusting the distance. Errors made during the adjustment process, This can lead to the mechanism being mispositioned, which in turn requires repeated correction. This leads to wasted time by requiring manual adjustments. Since it can vary depending on operator experience, in some cases production is 30 This can cause the process to stop and reduce efficiency. In current systems, the mechanism can jam and lock, rendering the press machine unusable. This makes it difficult. In current systems, the course / stroke change mechanism is long-term. It can become jammed and locked due to misuse or incorrect adjustments. This situation occurs with crankshaft 35. not fitting together properly, the shaft, connecting elements and adjustment mechanism, or This can be caused by reduced mobility of parts that wear out over time. Especially gears. 2 or factors such as sediment buildup in pin systems, lack of oil, or misalignment, This causes the mechanism to jam, preventing the stroke / course adjustment from being made. This occurs when the mechanism locks, forcing the operator to exert extra effort. attempting to repair it risks damaging the parts and disrupting production. This situation makes the machine more difficult to use and also reduces maintenance times. This prolongs the process and negatively impacts production efficiency. Traditional systems are not sufficiently resistant to wear and tear over long periods of use. This may not be possible, and this increases maintenance costs. Traditional course / stroke replacement. The components used in these systems involve continuously repeated mechanical movements, friction, and high 10 Because it is exposed to pressure, it can undergo wear and deformation over time. In particular, Moving components such as crankshafts, gear mechanisms, connecting pins, and guide rails, With prolonged use, the material may lose its sensitivity due to fatigue. This wear makes it difficult to accurately adjust the stroke / speed, affecting the machine's performance. This can have negative effects and create unwanted gaps or shifts. 15 As wear increases, parts need to be replaced or more frequent maintenance is required, which This leads to interruptions in production processes and additional maintenance costs, especially. In machines operating on high-volume production lines, this situation leads to significant cost increases over time. and can lead to operational inefficiencies. Complex adjustment mechanisms can lead to workplace accidents due to misuse or operator errors. This can be the reason. Stroke / course change with complex adjustment mechanisms. In these systems, operators need to be careful and experienced when making adjustments. In traditional systems, crankshaft and adjustment screws are used to adjust the stroke distance. Manual intervention on locking pins and other fasteners 25 It is necessary. If the operator does not follow the correct procedure or the parts are not properly installed If not locked, the system can behave unexpectedly and cause handshakes, crushing, or other incidents. It can also lead to injuries due to sudden mechanical reactions. Furthermore, incorrect adjustment can cause injuries. As a result, the stroke distance may not remain stable during machine operation, which can This causes the parts to move uncontrollably and create a hazard in the workplace. This is especially true in fast-moving production lines or for employees working under heavy workloads. In machinery, such faults risk operator safety, leading to an increase in workplace accidents. is happening.
