What are the rules for metal stamping die scrap tube?

The Purpose Standardize the management of the scrapping of the company's metal stamping dies, prevent the loss of company assets, and formulate this system specially. Scope of application It is suitable for the management of the company's scrap molds. Definition If the molds listed in the assets of the company fall under one of the following circumstances, the use management department may apply for scrapping. 1. Molds that exceed the specified service life. 2. The mold is severely damaged by accidents or accidents, and molds that cannot be repaired or have no repair value. 3. Metal stamping dies that have not reached the service life, but due to safety, quality, efficiency and other issues, the repair still fails to meet the minimum requirements of the customer's product process or affects the production safety and efficiency. 4. Product customers have stopped placing orders or have not placed orders for molds in several years. 4. Responsibilities 1. Responsibilities of th

How to prevent deformation during slow wire processing

 Slow-moving wire processing is a very exquisite and exquisite craft, and sufficient preparations need to be made, so that the processed products can be more quality. The slow-moving wire processing technology has a wide range of applications and is a must in our industries. If you want to do better with less technology, you must master all aspects of the processing knowledge. For example, the most common thing is the deformation during processing.  How can we solve it How to prevent deformation during slow wire processing Speaking of slow wire processing, it uses continuously moving fine metal wires as electrodes. Pulse spark discharge is performed on the workpiece, where it generates a high temperature above 6000 degrees. Moreover, if it wants to improve its quality problems and prevent its deformation, it can firstly start from the following aspects. 1. To prevent deformation, it is impossible for the material to have no internal stress. In particular, the internal stress of the que

The development of lock-up clutches

With the continuous development of automatic transmission technology, only relying on simple hydraulic control or electrical control to engage or disengage the lock-up clutch has exposed many problems. Therefore, the American General Motors Company took the lead in adopting the electronic control of the lock-up clutch in 1891, and other automobile manufacturers soon followed. So far, it can be said that almost all hydraulic lock-up clutches have adopted electronic control.

For the electronically controlled lock-up clutch, the action of the lock-up piston is controlled by the lock-up solenoid valve and one or several sliding plunger valves. When the lock-up occurs or is released, the solenoid valve controls the sliding plunger. The oil pressure signal of the valve action, and the sliding plunger valve really controls the oil pressure that makes the clutch piston engage and disengage. Since the electronic control methods or methods of automatic transmission lock-up clutches of major automobile manufacturers have their own characteristics, a few representative ones are selected and introduced below.

Chrysler Automobile Company's lock-up clutch electronic control

Chrysler Automobiles adopted electronic control of the lock-up clutch in 1986. The hydraulic oil circuit part of the control system, and its lock-up solenoid valve is controlled by the electronic control unit through a lock-up clutch relay. As for the signal sources that the electronic control unit relies on to determine whether to lock or not, they are the cooling water temperature sensor, the vacuum sensor, the vehicle speed sensor, and the throttle closing switch. Normally, only when the engine cooling water temperature is higher than 6o6C, the vehicle speed is higher than 6k4m/h, and the engine intake manifold vacuum is about 26.66-66.66kPa, lock-up can occur. When the engine cooling water temperature indicated by the water temperature sensor rises above 66°C, the electronic control unit can determine whether to lock the lockup clutch in the torque converter according to the signals from the throttle closing switch, vehicle speed sensor and vacuum sensor .

Whenever the throttle closing switch is in the closed state, the electronic control unit will not energize the lock-up solenoid valve and therefore will not lock the clutch. There is no doubt that the function of this switch is to notify the electronic control unit to release the lock of the lock-up clutch. In order to reduce exhaust pollution and increase fuel economy when the throttle is closed and slowing down.

In order to prevent the lock-up solenoid valve from being energized and de-energized repeatedly during the brief opening and closing of the throttle valve, there is a part of the electronic control unit program to ensure that the engagement action of the lock-up clutch is delayed for a given period after the throttle closing switch is turned on. time.
