[0015] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings and preferred embodiments.
[0016] like Figure 1 As shown, the utility model discloses a pipe cutting machine unloading and short material connection structure, including an up-and-down moving mechanism 1, a left-and-right moving mechanism 2 and a flipping mechanism 3, wherein the up-and-down moving mechanism is used to drive the left-and-right moving mechanism to move up and down, the left-and-right moving mechanism is used to drive the flipping mechanism to move left-and-right, the flipping mechanism is installed on the left-and-right moving mechanism, and the flipping mechanism is used to support and flip the steel. The up-and-down lifting mechanism is used to drive the left-and-right moving mechanism and the flipping mechanism on the upper part to move up and down.
[0017] like Figure 1As shown, the up-and-down moving mechanism includes a base 11, an upper and lower cylinder 12, a servo motor 13, a lead screw 14 and an up-and-down moving frame 15, wherein the upper and lower cylinders and the servo motor are respectively mounted on the base, and the up-and-down moving frame is respectively mounted with a cylinder connection block 16 and a lead screw seat 17, wherein the cylinder connection block is connected to the piston rod of the upper and lower cylinders, and the lead screw is threadedly matched with the lead screw seat. The cylinder drives the cylinder connection block to move up and down, and the servo motor drives the lead screw to rotate, and the lead screw drives the lead screw seat to move up and down. Since the lead screw seat and the cylinder connection block are both fixed on the up-and-down moving frame, the up-and-down moving frame can be driven to move up and down at the same time, and the up-and-down movement is realized by the servo motor and the lead screw. The cylinder is used to offset the weight of the frame that moves up and down, so that the servo motor used for the up-and-down movement only carries the weight of the cut pipe and the acceleration of the up-and-down movement. The reduction of the motor load can not only improve the dynamic following performance of the pallet, but also select a smaller motor to reduce the cost.
[0018] like Figure 2 As shown, a lifting arm 18 is fixed to one side of the up-and-down moving frame, and the upper end of the lifting arm is connected to the bottom of the left-and-right moving mechanism. The upper and lower cylinders are located below the lifting arm to support the lifting arm. The left-and-right moving mechanism includes a left-and-right moving cylinder 21, a left-and-right moving frame 22, a left-and-right moving base 23, a slide rail 24 and a slider 25. The left-and-right moving base is fixed to the upper part of the lifting arm, and the sliders are fixed on both sides of the upper part of the left-and-right moving base. The slider is slidably connected to the slide rail, and the slide rail is fixed to the bottom of the left-and-right moving frame. The left-and-right moving cylinder is fixed on the left-and-right moving base, and the piston rod of the left-and-right moving cylinder is connected to the bottom of the left-and-right moving frame. The left-and-right moving cylinder drives the left-and-right moving frame to move on the left-and-right moving base, and the slider is fixed on the left-and-right moving base, and the slide rail moves together with the left-and-right moving frame.
[0019] like Figure 3 As shown, the flip mechanism includes a support plate 31 and a flip cylinder 32. The flip cylinder is installed on the left and right moving frame. The piston rod of the flip cylinder is hinged to the support plate, and one side of the support plate is hinged to the left and right moving frame through a bearing. The flip cylinder drives the support plate to flip. When the cutting of short pipes is completed, the support plate will rotate a certain angle so that the short finished pipes can be collected together smoothly. For all pipes being cut, the finished part will fit tightly with the support plate at any time, so that the steel can be effectively supported in time, thereby improving the cutting accuracy.
[0020] When cutting long pipes, Figure 4 The state shown is that this mechanism is not used. When cutting short materials, Figure 5In the state shown, the short material is supported throughout the whole process, and it rotates with the chuck and moves up and down intelligently, so that the rectangular tube, square tube, etc. can be fitted with the pallet at all times. When the tube is cut, the pallet is flipped over to make the tube roll into the finished product car.
[0021] It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications should also be regarded as the protection scope of the utility model.
