The limit column is realized. After the positioning in the length direction is completed, in order to make the plate supported by the fixed platform, it is necessary to control the conveyor belt to drop into the belt groove of the fixed platform through the jacking cylinder, and then push it to the processing area by the push plate for punching. ; When the plate is finished processing, it is necessary to control the conveyor belt to rise to the top of the fixed platform through the jacking cylinder, and the plate will be lifted by the conveyor belt at this time, and then sent out by the conveyor belt to realize the discharge; that is to say, during the feeding process of the above plate , the conveyor belt needs to be raised or lowered repeatedly, and every time the sheet is punched, it needs to wait for the conveyor belt to be seated, and the next sheet must wait for the punched sheet to be completely conveyed before entering the fixed platform, which leads to waiting for feeding It takes a long time, especially when the length of the processing plate is short, then the plate needs to be driven by the conveyor belt for a certain distance before it can be punched, so the waiting time is longer, resulting in a very limited increase in the production efficiency of the hinge machine.

Contents of the invention

The purpose of the utility model is to propose a hinge machine for the above-mentioned problems in the existing technology. The technical problem solved by the utility model is how to improve production efficiency.

The purpose of this utility model can be achieved through the following technical solutions: a hinge machine, including a frame and a plate-like workbench fixed on the frame, is characterized in that, the frame is provided with a roller conveyor line, the The above-mentioned roller conveying line includes several rollers arranged at intervals along the length direction of the workbench and can rotate along the length direction of the workbench. A processing gap for drills to pass is formed between the inner side of the roller conveying line and the workbench, and a pushing device capable of pushing and pushing the plate into and out above the processing gap is provided on both sides of the processing gap.

By improving the feeding structure, this hinge machine directly shortens the processing time of the hinge machine for the plate, thereby better improving the production efficiency of the hinge machine; specifically, the hinge machine is designed on one side of the workbench by A roller conveyor line consisting of a row of rollers arranged at intervals along the length of the workbench and capable of rotating along the length of the workbench. The upper surface of the workbench is about less than 0.5mm higher. There is a processing gap for the drill bit to pass between the roller conveyor line and the workbench. By designing a pushing device on both sides of the processing gap, when the plate needs to When feeding, the plate is transported to the position by the roller conveying line, and pushed to the upper part of the processing gap by the pushing device on one side. After the plate is in place, the plate is pressed by the pressing device of the hinge machine and then drilled; after processing, When discharging, the pushing device on the other side pushes the board out of the processing gap, so that the whole board is in contact with the roller conveyor line, and at this time the board is conveyed by the roller conveyor line to complete the discharge; from the feeding process of the above hinge machine It can be seen from the analysis that due to the position of the above-mentioned roller conveyor line and the design that it is basically consistent with the height of the workbench and forms a processing gap, the roller conveyor line not only plays the role of conveying the plate, but also plays a role of supporting the plate, that is, The roller conveying line composed of several rollers actually plays a supporting role in the processing of the plate, that is to say, in the whole plate pressing process, because the roller conveying line has the functions of conveying and supporting at the same time, so The roller conveyor line itself does not need to be moved during the processing process, and there is no need to delay the feeding time to affect the smoothness of the entire feeding operation. This makes the hinge machine only need to carry out roller conveyor line feeding during the sheet material feeding process. , Pushing the material by the pushing device, processing operation, pushing out the material by the pushing device, and conveying and discharging the material by the roller conveyor line completes the entire feeding operation. Efficiency; at the same time, the roller conveyor line and the workbench form a processing gap so that the processing area of the plate is as close as possible to the roller conveyor line, which is the in-and-out conveying part, so that the feeding and pushing device of the pushing device can be saved The stroke of discharging and pushing the material further shortens the time required for the material feeding operation, thereby further improving the production efficiency of the hinge machine.
