A detection method for sticking mold failure of press

Abstract

The present invention designs the field of press moulds, specifically a method for detecting a sticking failure of a press. When a wheel formed by forging cannot be normally demoulded on a press mould: the detection method includes the following steps: the first step : Observe whether the pressure of the small demoulding cylinder is normal; Step 2: The pressure and establishment time of the small demoulding cylinder are normal, and observe whether the stroke value of the small demoulding cylinder on the monitoring interface of the press is normal; Step 3: Check whether the upper mandrel is deformed Step 4: Remove the upper mold of the press machine, check whether the demoulding ejector pin is deformed or broken; Step 5: Remove the mold and check the distance between the cylinder head of the demoulding small cylinder and the lower end of the large disc and the upper cross-section of the demoulding pole Whether the distance is consistent with the upper end surface of the mold base; the invention discloses a detection method for the mold sticking failure of the press. The invention checks the mold from the outside to the inside; greatly improves the production efficiency and reduces the labor intensity of workers; At the same time, the rolling quality is improved and production downtime is reduced.

Description

technical field [0001] The invention relates to the field of molds for presses, and specifically relates to a detection method for mold sticking failures of presses. Background technique [0002] Wheel rolling is one of the key links in the manufacturing process of train wheels, and it is also a key process of wheel quality control. However, in this process, it is often difficult or even impossible to remove the red steel from the upper mold after forging; the conventional processing takes a long time and the production efficiency is low, which not only increases the loss of the mold, but also affects the quality of the produced product, and even causes damage to the online mold. The phenomenon of forced production shutdown has brought huge and immeasurable losses to the company. [0003] Routinely adopts empirical troubleshooting, but due to the different technical capabilities of employees, the fault judgment and troubleshooting methods are different, and the fault point ...

However, in this process, it is often difficult or even impossible to remove the red steel from the upper mold after forging; the conventional processing time is long and the production efficiency is low, which not only increases the loss of the mold, but also affects the quality of the produced product, and even causes damage to the online mold. Forced to stop production and other phenomena, bringing huge and immeasurable losses to the company

[0003] Routinely adopts empirical troubleshooting, but due to the different technical capabilities of employees, the fault judgment and troubleshooting methods are different, and the fault point is not identified, blind trial and error, prone to multiple dismantling of molds and shutdown inspections, the production rhythm is completely disrupted, serious affect the overall production efficiency
