It can maintain the pressure at the dead point of the product and realize the product The edge is pressed, and the middle is stretched shallowly by a beating rod, which can well ensure the product is formed.

The technical solution adopted by the utility model to solve the technical problem is: to provide a punch press with a dead point pressure maintaining function using a cam drive, including a fuselage, a motor and a driven wheel, and a motor is installed horizontally on the fuselage. The main shaft of the motor protrudes toward the right side of the fuselage, and a driving wheel is installed on the main shaft, and a driven wheel connected with the driving wheel of the motor is installed on the upper part of the right side of the fuselage, and the driven wheel is installed on the side close to the fuselage. The output gear that the driven wheel rotates synchronously, the main gear meshing with the output gear is installed under the driven wheel, the slider that slides up and down is installed in the middle of the fuselage, the middle of the slider is leaked, and the leaked A cam is installed at the place, and a transmission shaft is installed between the cam and the main gear. The upper and lower parts of the slider are equipped with upper and lower wheels of the slider matched with the cam.

The driven wheel is connected with the output gear through a transmission shaft.

The driving wheel on the motor main shaft is connected with the driven wheel through a pulley structure.

A feeding structure is arranged at the stamping port of the fuselage, and the feeding structure is connected with the lower jacking gear in the lower part of the fuselage, and the lower jacking gear meshes with the lower side of the main gear.

The cam is connected with the transmission shaft through a connection key.

Beneficial effects: the utility model relates to a punching machine which adopts cam drive and has the function of maintaining pressure at the dead point. It has the characteristics of simple structure, high production efficiency, and stable product quality. The shallow stretching is carried out by the punching rod in the middle, which can well ensure the shape of the product.

detailed description

Below in conjunction with specific embodiment, further set forth the utility model. It should be understood that these embodiments are only used to illustrate the present utility model and are not intended to limit the scope of the present utility model. In addition, it should be understood that after reading the content taught by the utility model, those skilled in the art can make various changes or modifications to the utility model, and these equivalent forms also fall within the scope defined by the appended claims of the application.

The embodiment of the present utility model relates to a punch press which adopts cam drive and has dead point pressure maintaining function, as shown in Fig. Motor 2 is installed, and the main shaft of motor 2 stretches out toward the right side of fuselage 1, and driving wheel is installed on the main shaft, and the driven wheel 3 that links to each other with the driving wheel of motor 2 is installed on the upper part of fuselage 1 right side, described The side of the driven wheel 3 close to the fuselage 1 is equipped with an output gear that rotates synchronously with the driven wheel 3, the main gear 9 meshing with the output gear is installed below the driven wheel 3, and the upper and lower gears are installed in the middle of the fuselage 1 Sliding slider 5, the middle part of the slider 5 is leaky, a cam 4 is installed in the leaky place, a transmission shaft is installed between the cam 4 and the main gear 9, the upper and lower parts of the slider 5 The slider upper wheel 6 and the slider lower wheel 7 matched with the cam 4 are all installed.

The driven wheel 3 is connected with the output gear through a transmission shaft 8 .

The driving wheel on the main shaft of the motor 2 is connected with the driven wheel 3 through a pulley structure.

The punching port of the fuselage 1 is provided with a feeding structure, which is connected to the lower jacking gear 10 in the lower part of the fuselage 1 , and the lower jacking gear 10 meshes with the lower side of the main gear 9 .

Described cam 4 is connected with transmission shaft by connecting key.

Example

When the cam punch press is working, the motor 2 on the body 1 first starts the driving wheel to rotate, the driving wheel drives the driven wheel 3 through the belt, the driven wheel 3 drives the output gear through the transmission shaft 8, the output gear drives the main gear 9, the main The gear 9 drives the cam 4 and the lower jacking gear 10, and the lower jacking gear 10 can drive the feeding structure to work. The feeding structure sends the raw materials to the punching port of the punching machine, and at the same time controls the pressure of the punching machine and the position of the punching machine. After that, the cam 4 will control the slider 5 to continuously impact the product, so that the product is stretched to form a mold. When the convex part of the cam 4 touches the lower wheel 7 of the slider, the product is in a state of maintaining pressure. This kind of stamping using the cam method can It is convenient for the punching machine to keep the pressure on the dead point of the product, improve the production efficiency of the product, and ensure the quality of the product.
