[0016] 1. In the present invention, by setting a flattening device, firstly, the copper tube to be flattened is inserted into the surface of two semicircular rods, and the copper tube is supported by the two semicircular rods, and then the hydraulic cylinder is started to make the hydraulic rod drive the pressing plate to move downward, and the extrusion block at the bottom of the pressing plate will first contact with the extrusion grooves of the two first moving blocks, and the two extrusion grooves will make the two first moving blocks receive the extrusion force to both sides, so that the two first moving blocks move to both sides, thereby driving the two semicircular rods to move, so that the two semicircular rods form support for the copper tube inside the copper tube, so that the upper mold and the lower mold flatten the copper tube, and when the copper tube moves downward, the copper tube will contact the limit block, and the limit block is used to make the copper tube squeeze the semicircular rods, so that The semicircular rod squeezes the second spring, and the reaction force of the second spring is used to fix the position of the copper tube. After the pressing is completed, the upper mold moves up. At this time, under the action of the first spring, the entire fixed frame moves up to make the copper tube separate from the lower mold. At this time, the two semicircular blocks push the copper tube out of the semicircular rod under the action of the second spring, thereby facilitating unloading. Under the action of the cylinder, the two first moving blocks approach each other again, thereby facilitating the insertion of the next copper tube. This solves the problem that when the traditional device is flattened, the copper tube may be deformed during the flattening process due to the lack of support inside the copper tube, resulting in more defective products during the production of the copper tube, affecting the production of the copper tube and wasting raw material resources.

[0017] 2. In the present invention, by setting a grinding device, after the copper tube is pressed, one end of the copper tube is placed on the surface of the bottom block, and then the left hand holds the handle of the bottom block and the handle of the first slider tightly. At this time, the arc plate at the bottom of the first slider squeezes the copper tube, and the third spring is compressed, so that the copper tube is always subjected to the reverse force of the third spring, thereby fixing one end of the copper tube, and then starting the motor, the motor drives the grinding disc to rotate, and at this time, the burrs on the copper tube port can be grinded by directly holding the other end of the copper tube, and the ball inside the circular groove of the fixed block can move inside the circular groove, and the ball is connected to the bottom block through a connecting rod, so that only one end of the copper tube needs to be held to move the copper tube at a certain angle, which is convenient for grinding the copper tube, and the tail of the copper tube will not swing during grinding, which is more labor-saving.

[0018] 3. In the present invention, by setting an auxiliary device, when grinding, more copper chips will appear on the surface of the grinding wheel. At this time, the copper chips are protected by two protective plates to prevent them from flying around. The transparent plate is convenient for viewing the grinding of the copper tube while providing protection. At the same time, a small amount of copper chips will fly on the surface of the protective frame, and the copper chips may scratch fingers when cleaning.
