When the cutter is pressed down, the knife sharpening block is initially positioned in the feed groove under the action of the spring, and when the cutter enters the feed groove, the knife sharpening block grinds the cutting edge of the cutter; when the cutting edge completely enters the feed groove, the rod body is connected with the two conductive elastic sheets, the sharpening block retracts when the electromagnet operates to generate a magnetic field to adsorb the metal sheet, when the cutter is lifted, but the cutting edge passes through the area where the sharpening block is located, the rod body is not connected with the two conductive elastic sheets any more, and the sharpening block ejects out again to grind the cutting edge.
As a preferable scheme of the scheme, the lower end of the rod body is provided with an insulating rod, and the lower end of the insulating rod stretches into the rod body groove when the tool apron is not pressed down.
As a preferable scheme of the scheme, the opposite end surfaces of the two knife sharpening blocks are inclined planes.
The utility model has the advantages that: the on-off time of the control mechanism is synchronous with the time of the blade passing through the area where the sharpening block is located by controlling the on-off of the control mechanism through the rod body, so that the sharpening block is ensured to grind the blade, the blade is kept sharp, and the blade cannot become blunt along with repeated cutting.

Detailed Description
The technical scheme of the utility model is further described below through examples and with reference to the accompanying drawings.
Examples:
the embodiment is a cutter sharpening mechanism of a roll forming machine, as shown in fig. 1, comprising a cutter 3, a cutter holder 2 for fixing the cutter, a base 6 and a hydraulic cylinder 1 for driving the cutter holder to move up and down, wherein the base 6 is provided with a feed groove 8, the upper ends of the two sides of the feed groove 8 are respectively provided with a groove perpendicular to the feed groove, the first end of the groove is communicated with the feed groove 8, a sharpening block 7 and a sharpening block ejecting mechanism are arranged in the groove, the sharpening block 7 is fixedly arranged on the sharpening block ejecting mechanism, and the sharpening block ejecting mechanism is controlled by a control mechanism arranged on the cutter holder 2 and the base 6.
As shown in fig. 2, the sharpening block ejecting mechanism comprises an electromagnet 11, a spring 12 and a metal sheet 13, wherein the electromagnet 11 is fixedly arranged at the second end of the groove, two ends of the spring 12 are respectively connected with the electromagnet 11 and the metal sheet 13, and the sharpening block 7 is fixedly arranged on the metal sheet 13. When the electromagnet 11 is not electrified, the spring 12 is not compressed, and the sharpening block is ejected out of the groove, so that the sharpening block is positioned in the feed groove and can be contacted with the edge of the cutter; when the electromagnet is electrified, the metal sheet 13 is attracted by the electromagnet, the spring is compressed, and the sharpening block is retracted into the groove and is not contacted with the blade any more. In the embodiment, the opposite end surfaces of the two sharpening blocks are inclined surfaces, and the two opposite end surfaces of the two sharpening blocks in the feed groove form a V shape.
The control mechanism comprises a rod body 4 arranged on the tool apron 2 and a rod body groove 9 arranged on the base 6 for the rod body to extend into, the lower end of the rod body 1 is equal to the starting position of the cutting edge of the cutter, two sides of the rod body groove are respectively provided with a conductive elastic sheet 10, and the two conductive elastic sheets 10 are respectively electrically connected with a power supply and an electromagnet 11. In the process of pressing down the cutter, when the cutting edge passes through the height area where the sharpening block is located, the rod body is not in contact with the conductive elastic sheet, the electromagnet is not electrified, the sharpening block is positioned in the feed groove and is propped against two sides of the cutting edge, the cutting edge is ground in the moving process of the cutter, after the cutting edge passes through the height area where the sharpening block is located, the rod body is in contact with the conductive elastic sheet, the power supply and the electromagnet are conducted, the electromagnet is electrified to adsorb the metal sheet, so that the sharpening block is retracted into the groove, and the sharpening block is prevented from being in contact with the cutter body of the cutter. On the contrary, in the lifting process of the cutter, initially, the electromagnet is electrified, the sharpening block is positioned in the groove, when the cutter edge passes through the height area where the sharpening block is positioned, the electromagnet is powered off, the sharpening block pops up, and the cutter edge is ground in the moving process of the cutter.
