[0020] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings:

[0021] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the positions or elements referred to must have specific directions, be constructed and operated in specific directions. Therefore, they cannot be understood as limitations on the present invention.

[0022] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0023] like Figures 1 to 3 As shown, a small punching machine includes a supporting base 1, a work surface 2, a waste storage drawer 3, a punching machine base 4, a punching fixture 5, a punch 6 and a punching mechanism 7. The working table 2 is installed above the supporting base 1. The working table 2 is provided with a blanking trough 2a. The punching machine base 4 can be installed above the working table 2 by screws. The punching machine base 4 is C-shaped. The punching fixture 5 is installed at the lower part of the punching machine base 4. The material to be punched is placed on the punching fixture 5. The punch is installed at the upper part of the punching machine base 4. The punching mechanism 7 drives the punch 6 to punch the material on the punching fixture. The punching fixture 5 and the punch 6 are located directly above the blanking trough 2a. The positive projection of the punching fixture 5 and the punch 6 from top to bottom falls into the blanking trough 2a to ensure that the waste can fall into the blanking trough 2a area. The waste storage drawer 3 is slidably installed in the supporting base 1a, and the waste generated during punching falls into the waste storage drawer through the blanking trough 2a.

[0024] like Figure 4As shown, the punching mechanism 7 includes a servo motor 71, a synchronous wheel assembly 72, a main rotating shaft 73, an eccentric shaft 74, a connecting block 75, a connecting pin 76, a connecting rod 77 and a guide fixing sleeve 78. The servo motor 71 is installed below the worktable 2. The servo motor 71 drives the main rotating shaft 73 to rotate through the synchronous wheel assembly 72. The main rotating shaft 73 is rotatably installed in the punching machine base 4. The eccentric shaft 74 is installed in front of the main rotating shaft 73. The central axis of the eccentric shaft 74 is not coaxial with the central axis of the main rotating shaft 73. The eccentric shaft A connecting block 75 is installed in front of the shaft 74, and a connecting rod 77 is installed at the lower end of the connecting block 75 through a connecting pin 76. The connecting rod 77 is vertically sleeved in a guide fixing sleeve 78, and the guide fixing sleeve 78 is fixedly installed in the upper part of the punching machine base 4. The lower end of the connecting rod 77 extends from the guide fixing sleeve 78 to connect the punch 6. When the main rotating shaft 73 rotates, the eccentric shaft 74 is driven to rotate eccentrically. The eccentric shaft 74 drives the connecting rod 77 to move up and down through the connecting block 75, and the connecting rod 77 drives the punch 6 to move up and down.

[0025] Specifically, the synchronous wheel assembly 72 includes a first synchronous wheel, a synchronous belt and a second synchronous wheel. The first synchronous wheel is installed on the output shaft of the servo motor. The first synchronous wheel is connected to the second synchronous wheel through a synchronous belt transmission. The second synchronous wheel is fixedly installed at the rear end of the main rotating shaft 73. A sensor bracket 79 is installed in the punching machine base 4. The sensor bracket 79 is used to install a sensor (not shown) for detecting the second synchronous wheel, so as to accurately control the number of rotations of the second synchronous wheel and thus control the lifting position of the punch.

[0026] like Figure 5 and 6 As shown, the support base 1 is composed of a left bracket 1a, an upper bracket 1b and a right bracket 1c. The left bracket 1a and the right bracket 1c are separated to form a cavity 1d for placing a foot. The upper ends of the left bracket 1a and the right bracket 1c are respectively connected to the left and right ends of the upper bracket 1b by welding. The left bracket 1a, the upper bracket 1b and the right bracket 1c are surrounded to form an inverted shape. A work surface 2 is installed above the upper bracket 1b.

[0027] A waste storage drawer 3 and a tool storage drawer 8 are slidably installed in the upper bracket 1b. The upper bracket 1b is also provided with an empty slot corresponding to the position of the material drop slot 2a. The waste storage drawer 3 and the tool storage drawer 8 are both open structures at the top. There are two tool storage drawers 4 located on the left and right sides of the waste storage drawer 3 respectively. The waste storage drawer 3 and the tool storage drawer 4 can be pulled out from the front of the upper bracket 1a, which is convenient for dropping out the collected waste and taking out tools. The tool storage drawer 8 can be used to place tools such as punches and screwdrivers of different specifications.

[0028] like Figure 7As shown in the figure, the workbench surface 2 includes a bottom plate 2b, an inclined plate 2c, a raised plate 2d and a vertical plate 2e. The bottom plate 2b has the largest area, and above it is for installing the punching device of the punching machine. The blanking chute 2a is arranged on the bottom plate 2b. The four sides of the bottom plate 2b are connected to the inclined plate 2c, and the inclined plate 2c is inclined outward and upward. The inclined plate 2c is connected to the raised plate 2d. The raised plates 2d on the four sides are higher than the bottom plate 2b. The advantage of this is that it can limit the position so that the waste materials are always on the bottom plate 2b. The raised plate 2d is connected to the vertical plate 2e. There are 4 inclined plates 2c, raised plates 2d and vertical plates 2e respectively, while there is only 1 bottom plate 2b. A fence 9 for preventing waste materials from flying out is welded above the raised plate 2d. The fence 9 is in a U shape, and the front of the fence 9 is a single-sided opening structure, that is, it can effectively prevent waste materials from flying out without preventing the workers from operating.

[0029] The above content is a further detailed description of the present utility model in combination with specific preferred embodiments. It cannot be determined that the specific implementation of the present utility model is only limited to these descriptions. For those of ordinary skill in the technical field to which the present utility model belongs, without departing from the concept of the present utility model, several simple deductions or substitutions can still be made, and all of them should be regarded as belonging to the protection scope of the present utility model.
