Description

Technical Field

[0001] The utility model relates to the technical field of strip steel repair processing, in particular to a strip steel edge correction device. Background Art

[0002] Hot-dip galvanized steel strip is a metal material obtained through the hot-dip galvanizing process. It is primarily made from ordinary carbon steel strip that has been hot-dip galvanized. After production in the metallurgical industry, hot-dip galvanized steel strip is converted into coils and transferred using cranes. This process inevitably causes damage to the strip edges, which includes warping and burrs. Since hot-dip galvanized steel strip is the raw material for color coating, these edges must be repaired to prevent further production.

[0003] Under the existing technology, the method for dealing with the damage on the edge of the strip is: laying the strip flat and manually cutting off the damaged part of the strip edge using electric scissors or disc shears.

[0004] However, the existing technology for handling edge damage of strip steel has certain shortcomings and deficiencies: the steel with the damaged edge cut off will be treated as waste after processing, which to a certain extent causes a large waste of steel. Utility Model Content

[0005] The purpose of the utility model is to provide a strip steel edge correction device to solve the problem that cutting off the damaged portion of the strip steel edge will cause steel waste.

[0006] In order to achieve the above-mentioned purpose, the basic solution provided by the utility model is: a strip edge correction device, including a U-shaped shell, the two ends of the U-shaped shell are respectively connected to an extension shell one and an extension shell two, the extension shell one is provided with two connecting rods one, and the output ends of the two connecting rods one are rotatably connected to steel roller one, the extension shell two is fixedly connected to two connecting rods two, and one end of the two connecting rods two is rotatably connected to steel roller two, and a transmission component for moving steel roller one longitudinally is provided in the U-shaped shell.

[0007] The principle and beneficial effect of the present invention are as follows: by setting the outer shell of the correction device to be U-shaped, a steel roller 2 fixed in place and unable to move longitudinally is set at one end, and a steel roller 1 that can move longitudinally a certain distance is set at the opposite position of the other end, and the hand-held correction device is aligned with the edge of the strip on the conveyor, so that the edge of the strip is located between steel roller 1 and steel roller 2 and fits with steel roller 2, and the transmission component is used to drive steel roller 1 to move in the direction close to steel roller 2 until both steel roller 1 and steel roller 2 are fit with the strip. As the strip continues to move forward, the damaged parts of the edge of the strip will be processed, and since steel roller 1 and steel roller 2 can rotate freely, they will rotate in the direction of movement of the strip when fitting with the strip, and will not clamp the strip in place, thereby avoiding affecting the normal transportation of the strip.

[0008] Option 2, which is the preferred option of the basic option, includes a transmission assembly comprising a hose, one end of which passes through the U-shaped housing. Two pneumatic valves are fixedly attached to the inner wall of one side of the extension housing. The other end of the hose is connected to both pneumatic valves. One end of two connecting rods is located in the valve cavity of the two pneumatic valves, respectively. Both connecting rods pass through the extension housing. A pneumatic valve switch and a pneumatic pressure regulating switch are provided on the U-shaped housing. Both the pneumatic valve switch and the pneumatic pressure regulating switch are connected to the hose. By introducing compressed air into the hose, the pneumatic valve switch controls the opening of the pneumatic valve. The compressed air enters the valve cavity of the pneumatic valve, pushing the connecting rod 1 to move longitudinally downward, thereby driving the steel roller 1 to move in the direction of the steel roller 2. The pneumatic pressure regulating switch is used to adjust the air pressure to control the distance that the connecting rod 1 moves longitudinally downward.

[0009] Option 3, which is the preferred option of Option 2, is to provide a quick connector at one end of the hose outside the U-shaped housing. The quick connector facilitates the flow of compressed air into the hose, making it easy to access and ensuring airtightness.

[0010] Option 4, which is the preferred option of the basic option, has a pressure display instrument on the U-shaped shell, which is connected to the hose. The pressure display instrument makes it easy to know the air pressure changes in the hose in real time.

[0011] Solution 5, which is the preferred solution of the basic solution, has a handle fixed to the U-shaped housing. The handle makes it easier for the operator to hold the correction device and correct the edge of the strip.

[0012] Option 6, a preferred alternative to the basic option, features a hard chrome layer on the outer walls of both steel rollers 1 and 2. This hard chrome layer increases the hardness, corrosion resistance, and durability of both rollers, thereby improving their performance and lifespan. BRIEF DESCRIPTION OF THE DRAWINGS
