Description

Technical Field

[0001] The utility model relates to the field of edge milling machines, in particular to a steel plate edge milling and breaking device. Background Art

[0002] At present, in the spiral welded pipe unit, when welding the head and tail of the raw steel coil, when the steel plate exceeds 20 mm, when single-sided welding is performed, the weld is not fully melted, the weld height exceeds the standard, the performance does not meet the requirements, and it brings trouble to the finishing and repair welding of the steel pipe; in order to enhance the welding quality, it is often necessary to mill the edges of the steel plate.

[0003] In the prior art, a milling machine is needed to process the steel plate. When the milling machine is working, a clamp is needed to clamp and limit the steel plate, and a milling tool is needed to mill and cut the steel plate. However, when the clamp is used to clamp and limit the steel plate, if a traditional pneumatic clamp is used to clamp or press and fix the steel plate, the fixed steel plate cannot be flexibly moved according to the processing needs. If the upper and lower transmission rollers are used to press and drive the steel plate, although the steel plate can be pressed and moved horizontally forward and backward, the two sides of the steel plate cannot be limited, which can easily cause the steel plate to shift when it moves horizontally forward and backward, thereby affecting the overall processing quality.

[0004] Therefore, it is necessary to invent a steel plate edge milling and breaking device. Utility Model Content

When transmission roller A and transmission roller B are started to rotate (transmission roller A rotates forward, transmission roller B rotates reversely, and the two move in opposite directions), transmission roller A and transmission roller B can drive the steel plate to move horizontally and linearly.

[0010] Preferably, the milling edge breaking assembly includes a bracket and a turntable installed on one side of the upper end of the bracket, a rotating motor is installed on the other side of the upper end of the bracket, a driving device is fixedly installed on one end of the turntable away from the rotating motor, and a cutter head is installed on the output end of the driving device.

[0022] The beneficial effects of the utility model are:

[0023] 1. It is convenient to limit the conveying of steel plates and avoid the deviation of the conveyed steel plates. The transmission roller A and the transmission roller B are both composed of a first roller body and a second roller body. When the adjustment component is started, the adjustment component will drive the first roller body and the second roller body to move toward each other. The first roller body is inserted into the slot through a connecting rod. As the first roller body and the second roller body move toward each other, the connecting rod will gradually leak out, so that the overall length of the first roller body and the second roller body is extended. When the adjustment component drives the first roller body and the second roller body to move back, the connecting rod will be reinserted into the slot, so that the first roller body and the second roller body are close to each other and the distance is shortened, so that the length of the first roller body and the second roller body can be adjusted according to the width of the steel plate, so that the fixing frame fits on both sides of the steel plate, and the left and right displacement during the conveying of the steel plate is avoided.

[0024] 2. To avoid the separation of the first roller and the second roller after the length is adjusted, the two driving motors can respectively drive the transmission roller A and the transmission roller B to rotate in opposite directions, so that the steel plate moves horizontally and linearly, and the connecting rod is inserted into the inner side of the groove on the inner wall of the slot through the convex strip, so that the connecting rod rotates synchronously with the first roller and the second roller, ensuring that the first roller and the second roller will not separate during the rotation process.

[0025] 3. It is convenient to adjust the angle of the cutter head. The rotating motor can drive the turntable to rotate, and the turntable will also synchronously drive the driving device to rotate, so that the driving device drives the cutter head to tilt upward or downward, and the driving device can drive the cutter head to mill the edge of the steel plate, thereby meeting the processing needs of different angles of the steel plate.
