Description

U rib processing mold

technical field

The utility model relates to steel structure processing equipment, in particular to a U rib processing mold.

Background technique

U-shaped ribs in large steel structure bridges, also known as U ribs, are one of the most important components in steel structure bridges, with a large number and high precision requirements. At present, U-rib processing generally adopts rolling method and integral pressing method. Among them, the mold processing of the rolling method is relatively easy and does not require high equipment requirements, but the rolling method is difficult to ensure the cross-sectional shape, twist and straightness of the U rib. After processing, the workload of repairing is large, the product qualification rate is low, and the overall efficiency is low. The overall pressing method requires high processing precision of the die, high mold debugging costs, long cycle time and high equipment pressure requirements, and the current overall pressing equipment is only suitable for thin plates (6-8mm) and short U-ribs (less than 5m).

In some large-scale steel structure projects, such as steel bridges, the U ribs used in steel bridges have a thickness of 12mm and a length of 10-15m. For the overall pressing of the U-rib of this project, the current equipment pressure is difficult to meet the requirements. So just need a kind of new processing mold that is suitable for the integral press processing of the U rib plate of large-scale steel structure.

Utility model content

The utility model aims at proposing a U-rib processing mold suitable for the integral pressing and processing of large thick U-rib plates.

According to an embodiment of the utility model, a U-rib processing mold is disclosed, which includes an upper mold, a lower mold and a driver. The upper die is rod-shaped with an extended head. The lower mold has a groove, the position of the groove corresponds to the position of the upper mold, and the width of the groove is greater than the width of the head of the upper mold. The driver is connected to the upper mold, and the driver drives the upper mold to press into the groove of the lower mold.

In one embodiment, the U rib processing mold further includes a steel plate thickness gauge and a controller. The steel plate thickness gauge measures the thickness of the steel plate to be processed. The controller is connected to the steel plate thickness gauge and the driver, and the controller calculates the processing stroke and processing pressure according to the thickness measured by the steel plate thickness gauge and provides them to the driver.

The U-rib processing mold of the utility model adjusts and compensates the pressing stroke and pressure of the mold according to the thickness of the steel plate. It is processed by one-time bending method, and the U-rib straightness, side bending and twist degree obtained by processing all meet the design standards, and the quality Stable and reliable.

Detailed ways

Referring to Fig. 1, it discloses a structural diagram of a U-rib processing die according to an embodiment of the present invention, the U-rib processing die comprises an upper die 102, a lower die 104, a driver 106, a steel plate thickness gauge 108 and a controller 110.

FIG. 2 discloses a structural view of the upper and lower molds 102 and 104 of the U-rib processing mold. As shown in FIG. 2, the upper mold 102 is rod-shaped and has an extended head 101 whose diameter is larger than that of the rod-shaped portion. The lower mold 104 has a groove 103, the position of the groove 103 corresponds to the position of the upper mold 102, the width of the groove 103 is greater than the width of the head 101 of the upper mold 102, so that the head 101 can enter the groove 103 smoothly.

Returning to FIG. 1 , the U rib processing mold also has a driver 106 , a steel plate thickness gauge 108 and a controller 110 . The driver 106 is connected to the upper mold 102 , and the driver 106 drives the upper mold 102 to press into the groove 103 of the lower mold 104 . The steel plate thickness gauge 108 measures the thickness of the steel plate 200 to be processed. The controller 110 is connected to the steel plate thickness gauge 108 and the driver 106 , and the controller 110 calculates the processing stroke and the processing pressure according to the thickness measured by the steel plate thickness gauge 108 and provides them to the driver 106 .

The working process of the U-rib processing mold is as follows: the steel plate thickness gauge 108 first measures the thickness of the U-rib plate. The controller 110 sets bending stroke and pressure compensation parameters according to the measured steel plate thickness. The controller 110 also aligns the bending center of the steel plate with the center of the upper die 102 . Then the controller 110 controls the driver 106 to drive the upper mold 102 to move down into the groove 103 of the lower mold 104 , and controls the stroke and pressure of the upper mold 102 during the movement to fold the steel plate 200 to form a U rib.

The U-rib processing mold of the utility model adjusts and compensates the pressing stroke and pressure of the mold according to the thickness of the steel plate. It is processed by one-time bending method, and the U-rib straightness, side bending and twist degree obtained by processing all meet the design standards, and the quality Stable and reliable.
