Need the position of manual control work piece like this, unable automatic feeding and ejection of compact, and this structure setting makes the metal fillings that cutting or tapping cut down can't be in time arrange down from product or work piece, and then influence the follow-up operation of work piece, and these pieces scatter and also influence the smooth operation of device in operational environment simultaneously, and the piece still can get into the human body, influences staff's healthy.

Disclosure of Invention

The invention aims to provide a numerical control punching device, which can realize automatic feeding and automatic drilling, can complete automatic discharging and reduce labor consumption.

In order to achieve the purpose, the basic scheme of the invention is as follows: a numerical control punching device comprises a conveying mechanism and a processing mechanism;

the conveying mechanism comprises a limiting groove, a push block and a conveying belt, the width of the limiting groove is equal to the width of one object to be processed or the sum of the widths of a plurality of objects to be processed, the push block is attached to two sides of the limiting groove and is in sliding connection with the limiting groove, and the conveying belt is located on one side of the limiting groove, is communicated with the limiting groove and is used for conveying the objects to be processed to the limiting groove;

the processing mechanism comprises a processing chamber, the processing chamber is communicated with one end of a limiting groove far away from a conveying belt, a placing plate is arranged in the processing chamber close to the limiting groove, one end of the placing plate far away from the limiting groove is rotationally connected with the side wall of the processing chamber through a rotating shaft, the rotating shaft is connected with a rotating mechanism for controlling the rotation of the processing chamber, a rotating rod is also arranged in the processing chamber and is positioned at one side of the placing plate far away from the limiting groove, the middle part of the rod body of the rotating rod is connected with a control mechanism for controlling the rotation of the placing plate, the two ends of the rotating rod are respectively articulated with a first articulated rod and a second articulated rod, one end of the first articulated rod far away from the rotating rod is articulated with the top of a push block, one end of the second articulated rod far away from the rotating rod is articulated with a connecting rod, one end, after the push block pushes the object to be processed to the placing plate, the punching assembly punches holes in the object to be processed.

The working principle and the beneficial effects of the basic scheme are as follows: the conveying mechanism can smoothly convey the object to be processed into the processing chamber so as to facilitate drilling. The conveyer belt will treat that the processing thing conveys to the spacing groove, makes and treats that the processing thing is placed side by side in the spacing groove, and the width of spacing groove can control the conveyer belt and carry into the number of the processing thing of treating of spacing groove, avoids the conveyer belt to convey too much or too little processing thing to the spacing inslot of treating, and the output of punching on the subassembly corresponds not to match and leads to processing accident or machining error. And the width of the limit groove is set, so that the object to be processed can be abutted against the side wall of the limit groove, and when the push block pushes the object to be processed in the limit groove to move to the processing chamber, the object to be processed can be prevented from being inclined due to a gap between the object to be processed and the side wall of the limit groove, and the end face to be processed of the object to be processed is ensured to face the punching mechanism all the time.

The process of punching sets up in the processing chamber, and the waste material piece that produces when can avoiding punching scatters in the external environment to prevent that the piece from getting into the human body and endangering staff's health, also reduce the work load that the staff cleaned the external environment. The processing mechanism is favorable for the rotating rod, the first hinge rod and the second hinge rod to form a type crank double-slider structure, the first hinge rod is connected with the pushing block, the pushing block is attached to two sides of the limiting groove, the pushing block can only move linearly along the limiting groove, and the purpose that the rotating is changed into the linear motion is achieved. In a similar way, the second hinge rod is hinged with the connecting rod, the connecting rod is connected with the punching assembly, the two side walls of the punching assembly are attached to the inner wall of the processing chamber, and the punching assembly can only move linearly along the inner wall of the processing chamber to form a structure similar to a slider-crank. And first hinge bar and second hinge bar are located the both ends of dwang respectively, and when the dwang rotated for the ejector pad with punch the subassembly relative motion, thereby made the ejector pad promote treat that the processing thing is close to gradually with the subassembly that punches, accomplish and punch.

Treat that the processing object gets into on the board of placing of processing chamber from the spacing groove, place board one end and rotate with the processing chamber and be connected, then place the board and can realize the luffing motion, slewing mechanism places the board wobbling position through pivot control, when needing to accept and treat the processing object, slewing mechanism control pivot rotates, and the pivot is connected with placing the board, then drives and places the board and swing to horizontal position, makes the terminal surface orientation subassembly that punches of treating the processing object. After punching is completed, the rotating mechanism controls the rotating shaft to rotate, so that the placing plate gradually swings downwards, the object to be processed rolls off from the placing plate, and automatic blanking is realized.

Further, the punching assembly comprises one or more than one parallel punching machine, and the punching machine is opposite to the surface to be punched of the object to be processed on the placing plate.

The subassembly of punching like this can set up according to the width of spacing groove, and sets up corresponding puncher quantity, satisfies the demand of once processing subassembly quantity.

The chip removing mechanism comprises a collecting chamber positioned below the placing plate and a piston cylinder positioned in the processing chamber;

the collecting chamber is communicated with the processing chamber, a vertical partition plate is fixedly connected to the bottom in the collecting chamber, a transverse bearing plate is hinged to the top of the partition plate, a supporting spring is arranged between the bearing plate and the partition plate, the bearing plate is located below the tail end of the inclined placing plate, a vertical screen plate is arranged on one side, away from the placing plate, of the bearing plate, and the bottom of the screen plate is fixedly connected with the top of the partition plate;
