Description

Technical Field

[0001] The utility model relates to the field of machine tool processing, in particular to a metal plate processing machine tool. Background Art

[0002] With the development of industrial technology, the existing machine tool equipment has become more and more perfect. In the field of steel plate processing, machine tools need to be used for back and forth cutting. The corners of square steel plates are very sharp. Workers are easily injured by sharp corners when they carry them manually. When both sides of the steel plate need to be processed, after processing one side of the steel plate, the worker needs to turn it over and process the other side, which will consume a lot of manpower.

[0003] Just like the gantry type CNC drilling, milling and boring steel plate automatic processing compound machine tool announced in Chinese patent application number CN201811095705.0, the gantry type CNC drilling, milling and boring steel plate automatic processing compound machine tool includes a workbench, a gantry frame, a steel plate placement frame, a positioner installation frame, and a control cabinet. The steel plate placement frame is fixedly installed on the workbench, and the steel plate placement frame is located in the positioner installation frame. A gantry motor is installed on the workbench. The positioner installation frame includes four positioning rails that are assembled into a rectangle as a whole. Multiple positioning supports are slidably installed on each positioning rail, and each positioning support is installed with a positioning sensor. The device is highly integrated and can realize integrated drilling, milling and boring when processing steel plates, saving floor space and equipment purchase costs. In addition, due to the presence of positioning supports and positioning sensors, the forming effect of the steel plates processed by the utility model is better;

[0004] The device also has the following disadvantages when in use. First, if both sides of the steel plate need to be processed, then one side of the steel plate needs to be taken out and turned over after processing, and then the steel plate is stuffed in to reprocess the other side. Second, the equipment is difficult to debug, which will waste a lot of manpower to debug and reduce work efficiency. Third, the steel plate is relatively heavy, and manually filling it into the interior of the machine tool is also dangerous. If there is insufficient space for the filler, it is easy to cause fatigue to the staff. Utility Model Content

[0016] Beneficial effects of the utility model:

[0017] Firstly, when the device is in use, the steel plate to be processed is clamped in the rectangular clamping cavity in the middle of the flipping plate. After one side of the steel plate is processed, the transport motor drives the transport roller to rotate, and the transport belt between the transport rollers drives the positioning plate to move. At this time, the positioning plate slides back and forth along the transport line groove. While the positioning plate moves in a straight line, the translation gear at the end of the flipping plate will be toggled by the rack in a fixed position, and the flipping plate will be twisted 180 degrees while translating until the side wall of the flipping plate fits on the resisting particles. Compared with the processing machine tools in the prior art, the previous machine tools still need to manually take out the steel plate, turn it over and put it back in after processing one side of the steel plate, which will waste a lot of manpower to operate and increase labor costs. The equipment can automatically flip the steel plate by stepping, and the position of the flipping plate and the steel plate is also changing, achieving the effect of automatic flipping of the steel plate and automatic positioning.

[0018] Secondly, if the machine tool equipment of the prior art needs to replace the processing device, it is more troublesome to debug. When the device processes the steel plate, the stepper motor drives the notch frame to rotate back and forth, and the wire grooves at both ends of the notch frame will lift the lifting square rod back and forth. When the lifting square rod on the left end rises, the lifting square rod on the right end will fall down, and the work station plate at the bottom of the lifting square rod is equipped with a grinding motor and a punching motor. After the punching motor punches a shallow hole on one side of the steel plate, the steel plate is turned over to let the grinding motor fall down to mill out a circular cavity. Compared with the equipment of the prior art, the grinding motor and the punching motor are removed during debugging and replaced with other processing equipment, which makes debugging more convenient.

[0019] Thirdly, the square steel plates processed by the machine tools of the prior art have sharp corners, and workers are easily injured by the sharp corners when manually carrying them. If the loading and unloading workspace is relatively small, this will cause certain troubles to the operators. When feeding the device, the steel plate is first placed on the outside of the device, and then the unloading motor drives the first bevel gear to rotate through the second bevel gear. The first bevel gear will drive the swing arm to twist back and forth 180 degrees. The lifting piece at the end of the swing arm can move up and down a short distance along the short groove. The output end of the expansion cylinder contracts and drives the lifting piece to fall down to pinch the steel plate, and wait until the lifting piece is twisted to the top of the flip plate and put it down. Compared with the equipment of the prior art, which still requires the staff to reach into the mechanical equipment to change materials, the equipment also has a certain safety to prevent the staff from being injured by complex mechanical corners.

[0020] Fourthly, when the steel plate is in the middle position of the two clamping blocks, the clamping cylinder drives the clamping blocks to start closing the clamped steel plate. The rubber strips on the side walls of the clamping blocks will lock the side walls of the steel plate. If the width of the steel plate is too large, the corner of the steel plate will contact the inclined block. The inclined block and the telescopic block apply pressure to the corner of the steel plate through the reset spring. Compared with the steel plate clamping mechanism of the prior art, if the width and length of the steel plates are different, it is necessary to debug the clamping mechanism back and forth, which is a waste of manpower.

[0021] Fifth, the machine tool equipment in the prior art needs to be moved, and the weight of the machine tool is relatively large. If it is to be moved over a long distance, a forklift is required. If the workstation is to be moved over a short distance, several people are required to carry it. However, the existing machine tool equipment has no place to hold it with hands when it is carried away, and it is generally more laborious to carry it. The four sides of the load-bearing frame of the device are provided with holding openings, and objects such as wooden sticks can be inserted into the holding openings. A total of four workers work together to lift it, and the force is more balanced, so it is more stable during the transportation process. BRIEF DESCRIPTION OF THE DRAWINGS

The first bevel gear 503 will drive the swing arm 506 to twist back and forth 180 degrees, and wait until the swing arm 506 is twisted to the top of the flip plate 204 and is dropped down. Compared with the equipment in the prior art, it still requires the staff to reach into the mechanical equipment to change materials. The equipment also has a certain degree of safety to prevent the staff from being injured by complex mechanical corners. The lifting piece at the end of the swing arm 506 can move up and down a short distance along the short slot 508, and the output end of the expansion cylinder 509 contracts to drive the lifting piece 507 to fall down and pinch the steel plate.

[0045] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
