Description

Technical Field

[0001] The utility model relates to the field of bending machines, in particular to an upper die of an opposite synchronous bending machine. Background Art

[0002] In the traditional technology of opposite synchronous bending machines, the replacement and adjustment of dies often take a lot of time and labor. The traditional method usually uses fixed dies. When it is necessary to change the bending process or product specifications, the operator needs to manually disassemble and install new dies, which is not only inefficient but also likely to cause equipment wear and operator fatigue. In addition, the versatility and flexibility of traditional dies are poor, making it difficult to meet diverse and personalized bending requirements, thus restricting the improvement of production efficiency and product quality. Content of the Utility Model

A horizontal pulley is fixed to the inner side of one group of hollow plates. A vertical pulley is fixed to the lower side of the hollow plate. Another group of hollow plates is fixed to the lower side of the vertical pulley. A fixing plate is fixed between the two groups of hollow plates.

[0007] The sliding member is composed of two groups of hollow plates, horizontal pulleys, vertical pulleys and a fixing plate. Flexible sliding and positioning in the horizontal and vertical directions are realized through the contact between the pulleys and the connecting plate.

[0010] Preferably, the top of the horizontal pulley is in close contact with the connecting plate.

[0011] Preferably, the vertical pulley is in fitting contact with the side surface of the connecting plate.
