Description

Technical Field

[0001] The utility model relates to the technical field of cold shearing machines, in particular to a temperature monitoring mechanism for an eccentric shaft of a cold shearing machine tool rest. Background Art

[0002] The cold shear is an important equipment in the steel rolling finishing area. It is usually installed at the end of the output roller of the cooling bed and is used for cutting the heads and tails of bars and flat steel finished rolled products and cutting to length. It has two lubrication methods: dry oil and thin oil. The dry oil lubrication method does not have a complete and effective monitoring device, and the pipeline of the dry oil automatic lubrication system is compact and hidden. In the long-term operation, it may cause the distributor to fail or the pipeline to be blocked or damaged, resulting in insufficient lubrication of the lubrication point and equipment failure. In particular, the copper sleeve of the eccentric shaft of the upper tool holder of the cold shear is a very important lubrication part of the lubrication point of the cold shear. If the lubrication is insufficient, the temperature of the copper sleeve on the eccentric shaft of the upper tool holder will be too high, causing the copper sleeve to burn and the spindle to get stuck. It takes at least 3 days to replace the copper sleeve each time.

[0003] In the actual production process, the equipment is often online for a long time, and it is impossible to frequently open the shell for comprehensive inspection and maintenance. In addition, since the copper sleeve of the eccentric shaft is inside the cold shear body, it cannot be directly observed without opening the cover. Daily inspection can only use a handheld temperature measuring gun to measure the temperature of the copper sleeve shaft hole shell. However, the shell is thick, and the measured temperature cannot truly reflect the actual temperature of the internal bearing part, resulting in the failure to find hidden faults in time during inspection, causing the copper sleeve to be burned, causing equipment shutdown, and seriously affecting work efficiency. Utility Model Content

[0004] The utility model aims to provide a temperature monitoring mechanism for an eccentric shaft of a cold shearing machine tool holder, so as to solve at least one aspect of the problems and defects raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A temperature monitoring mechanism for an eccentric shaft of a cold shearing machine tool holder, comprising:

[0007] A cold shear body, wherein the cold shear body has a shell;

[0008] A tool holder device is arranged in the housing;

[0009] The tool holder device is provided with an upper tool holder and a lower tool holder;

[0010] A connecting rod power system is arranged on the top of the upper tool holder;

[0011] The connecting rod power system includes an eccentric shaft, one end of which is connected to the output shaft of the upper tool holder;

[0012] A copper sleeve is provided on the eccentric shaft body;

[0013] A through hole is provided at the shell corresponding to the eccentric shaft, and a temperature sensor is provided in the through hole;

[0014] The temperature sensor is connected to the copper sleeve.

[0015] The eccentric shaft temperature monitoring mechanism of the cold shearing machine according to this solution has at least the following technical effects:

[0016] By opening a through hole at the shell corresponding to the eccentric shaft, arranging a temperature sensor in the through hole, and connecting the temperature sensor to the copper sleeve on the eccentric shaft, the temperature change of the eccentric shaft can be monitored in real time, which is conducive to timely discovering the abnormal temperature of the eccentric shaft and avoiding the malfunction of the dry oil lubrication system of the cold shear machine, which leads to excessive temperature of the eccentric shaft, causing the copper sleeve to burn and the main shaft to get stuck; it gets rid of the uncontrollable phenomenon of dry oil lubrication failure of the cold shear machine, can timely discover and deal with the abnormal temperature of the eccentric shaft, effectively prolongs the service life of the eccentric shaft, and at the same time avoids production interruption caused by failure, thereby improving production efficiency and equipment reliability.

[0017] As a further solution of the utility model: a tool holder seat is arranged at the lower part of the lower tool holder.

[0018] Since a knife holder seat is provided at the lower part of the lower knife holder, the knife holder seat, as a supporting point of the knife holder device, can stably bear the weight of the knife holder and prevent the knife holder from tilting or sinking, thereby ensuring the stability and accuracy of cutting.

[0019] As a further solution of the utility model: it also includes a real-time temperature tracking system.

[0020] Since the temperature monitoring mechanism of the eccentric shaft of the cold shearing machine tool holder also includes a real-time temperature tracking system, the temperature changes of the eccentric shaft can be visually monitored in real time through the system, and abnormal conditions can be discovered in time, which is conducive to early detection of faults in the distributor of the cold shearing machine dry oil lubrication system or blockage or damage of the pipeline, thereby avoiding excessive eccentric shaft temperature and resulting in burning of the copper sleeve on the eccentric shaft.

[0021] As a further solution of the utility model: it also includes a high temperature alarm device.

[0022] Since the temperature monitoring mechanism of the eccentric shaft of the cold shearing machine tool holder also includes a high temperature alarm device, the high temperature alarm device can promptly issue an alarm when the eccentric shaft temperature is abnormal or the temperature exceeds a set threshold, which helps the operator to promptly detect abnormal eccentric shaft temperature so as to take corresponding measures.
