Description

a cutting machine

technical field

The utility model relates to the field of cutting, in particular to a cutting machine.

Background technique

During the cutting process of the material tape, the material tape is often driven by the cutter to slide or curl. The cutter cannot cut effectively and quickly, and the finished product is prone to burrs, which affects the appearance of the product and has a high rate of defective products. At the same time, tool wear is also faster, reducing tool life.

In the prior art, in order to prevent the belt from sliding or bending due to the cutting knife, one way is to install a pressure plate on the mounting seat of the upper knife, and the pressure plate moves down with the upper knife to hold down the material belt, but The premise of this method is that the material tape needs to be flat before cutting, which requires manual operation by the operator, and the work efficiency of the operator is low. Another way is to set a clamping plate above the lower knife, and the clamping plate is fixedly installed on the workbench. When cutting, let the material belt be located between the lower knife and the clamping plate, and the material belt will be fixed by the clamping plate. Fixed, but in order to pass the material, there must inevitably be a gap between the binder plate and the material belt, which makes the material belt still easy to be driven by the cutter to slide or bend, and the above technical problems cannot be effectively solved.

Utility model content

The purpose of the utility model is to provide a cutting machine which can effectively position the material belt during the cutting process.

The utility model is in order to realize above-mentioned object, and the technical solution that adopts is:

A cutting machine, comprising a frame, a workbench, an upper knife, an upper knife mounting seat, and a lower knife, the upper knife mounting seat is slidingly connected to the frame up and down, the upper knife is installed on the upper knife mounting seat, and the lower knife is fixed on the workbench And set relative to the upper knife. A pressure plate is arranged above the lower knife; the pressure plate is floatingly arranged on the workbench through a floating material block, and the floating material block lifts the pressure plate so that the pressure plate is in contact with the pressure plate. There is a gap between the cutting edges of the lower knife for the material to be cut to pass through; the upper knife mounting seat is provided with a pressure plate guide post for moving downward with the upper knife mounting seat to push the pressure plate down.

Further, the frame includes an outer guide column, and the upper knife mounting seat is slidably connected to the outer guide column up and down.

Further, an inner guide post is provided on the upper knife mounting seat, and an inner guide post hole that can cooperate with the inner guide post is provided at a position opposite to the inner guide post on the workbench.

Further, positioning pins are provided on the upper knife mounting seat.

Further, positioning pinholes are provided on the pressing plate at positions opposite to the positioning pins.

Further, the gap is 1 mm.

The beneficial effects that the utility model can produce: the utility model is provided with a clamping plate that can move up and down on the cutting machine. Effective positioning of the material belt, so that the product can be cut quickly and simply during cutting, which can effectively improve the service life of the tool, reduce tool wear, reduce product burrs, effectively improve product appearance defects, effectively reduce life maintenance time, and improve Production efficiency and product quality.

Detailed ways

Below in conjunction with accompanying drawing 1～3, the specific embodiment of the present utility model is described in further detail.

As shown in FIGS. 1-3 , a cutting machine is used for cutting product strips, including a frame 9 , a workbench, an upper knife 4 , an upper knife mounting seat 3 , and a lower knife 8 . The upper knife mounting base 3 is slidingly connected to the frame 9 up and down, the frame 9 includes the outer guide column 1, the upper knife mounting base 3 is slidingly connected to the outer guide column 1 up and down, and the upper knife mounting base 3 is driven by the cutting cylinder along the outer guide column. 1 up and down motion. The upper knife 4 is installed on the upper knife mounting seat 3 , and the lower knife 8 is fixed on the workbench 10 and arranged opposite to the upper knife 4 .

The top of the lower knife 8 is provided with a binder plate 7, the binder plate 7 is floatingly arranged on the workbench 10 through the floating material block 11, and the floating material block 11 lifts the binder plate 7 so as to realize that the binder plate 7 and the lower material plate 7 are connected together. Leave between the cutting edge of knife 8 for the gap that the material belt to be cut passes through. The outer edge of the binder plate 7 is facing the edge of the upper knife 4 and the lower knife 8, so that when the upper knife 4 moves down to the binder plate 7, it will fit the edge of the binder plate 7 and the edge of the lower knife 8 Cut the tape. The gap between the holding plate 7 and the edge of the lower knife 8 for the material to be cut is preferably 1 mm. During actual use, the gap is selected according to the size of the material.

The upper knife mounting seat 3 is provided with a pressing plate guide post 2 for following the upper knife mounting seat 3 to move downward so as to push the pressing plate 7 down. During cutting, the pressing plate guide post 2, the upper knife 4, and the upper knife mounting seat 3 move down as a whole, and the pressing plate guide post 2 will contact the pressing plate 7 first, and then cut after pressing the material belt. This requires that the distance between the bottom end of the platen guide column 2 and the plane where the workbench 10 is located is greater than the distance between the bottom end of the upper knife 4 and the plane where the workbench 10 is located.

The upper knife mounting seat 3 is also provided with an inner guide post 6, and the inner guide post 6 also moves up and down following the upper knife mounting seat 3. The position opposite to the inner guide post 6 on the workbench 10 is provided with a The inner guide post hole 12.

The upper knife mounting seat 3 is also provided with a positioning pin 5, and the positioning pin 5 is installed on the upper knife mounting seat 3 through the positioning needle seat. The positioning pin 5 is located between the platen guide post 2 and the upper knife 4 . Positioning pinholes 13 are provided on the holding plate 7 at positions opposite to the positioning pins 5 .

When the cutting cylinder is at the origin, the pressing plate guide column 2 follows the upper knife 4 and the positioning pin 5 to rise to the highest point, and the pressing plate 7 has a certain clearance with the floating material block 11 top height, which is convenient for material passing. When the cutting cylinder is working, the pressure plate guide column 2 is pressed down following the upper knife 4 and the positioning pin 5, and the pressure plate 7 is pressed down until it fits with the product material belt and the lower knife 8, and finally pressed down to the upper knife 4 Cut the product. The whole process is completed, and the key is that the pressing plate 7 can press the material belt, which is convenient for the upper and lower knives to cut the product, and will not produce other directions of force, so that the product can be cut quickly and simply. It can greatly reduce the defective rate of products, improve the work efficiency of operators, and reduce the employment cost of enterprises. Make the whole process of the product strip in the best working condition, and improve the working conditions of the workers.

Of course, the above description is not a limitation of the present utility model, and the present utility model is not limited to the above-mentioned examples, and changes, modifications, additions or replacements made by those skilled in the art within the essential scope of the present utility model are also acceptable. Should belong to the protection scope of the utility model.
