AI Technical Summary
The existing punch press slide is prone to rebound or vibration when falling, which leads to unstable contact between the upper die and the workpiece and affects the stamping quality.
A buffer cavity is set in the main body of the punch press slide, and several buffer plates are set on the guide post 4. The buffer plates are slidably connected to the guide post 4 and are slidably connected to the guide post 4 through the elastic plate 5. The buffer plate and the guide post are slidably connected. The buffer cavity is equipped with elastic plates and elastic pads, which are made of rubber to reduce noise and damping.
It effectively reduces the springback tendency of the slider, ensures the smoothness of the stamping process, reduces noise, and improves stamping quality.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of punch press parts, and more specifically, it relates to a punch press slide. Background Technology
[0002] The design principle of a punch press is to convert circular motion into linear motion. The main motor drives the flywheel, which in turn drives the gears, crankshaft (or eccentric gear), connecting rods, etc., via the clutch to achieve the linear motion of the slide. The slide drives the upper die to stamp the workpiece, thus completing the production of stamped parts. However, when the slide falls and brings the upper die into contact with the workpiece, the workpiece also exerts an upward force on the upper die and the slide, which may cause the slide to rebound or vibrate slightly. This results in unstable contact between the upper die and the workpiece, affecting the stamping quality. Utility Model Content
[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a punch press slide.
[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a punch press slider, including a main body, a buffer cavity is provided in the main body, and a plurality of buffer plates are provided in the buffer cavity, the buffer plates being movable in the vertical direction relative to the main body.
[0005] The present invention is further configured such that: a guide post is fixedly connected between the inner bottom surface and the inner top surface of the buffer cavity, the buffer sheet is sleeved on the guide post, and the buffer sheet is slidably connected to the guide post.
[0006] The present invention is further configured such that an elastic sheet is provided between adjacent buffer sheets.
[0007] The present invention is further configured such that the thickness of the elastic sheet is less than the thickness of the buffer sheet.
[0008] The present invention is further configured such that: the inner top surface and the inner bottom surface of the buffer cavity are provided with elastic pads coaxial with the guide post.
[0009] The present invention is further configured such that the radius of the elastic pad is greater than the radius of the buffer sheet.
[0010] In summary, this utility model has the following beneficial effects: when the main body falls slowly, the buffer plate applies a downward force to the main body under the action of inertia, reducing the rebound tendency of the main body and ensuring the impact force of the stamping, ensuring the smooth stamping process. Both the elastic plate and the elastic pad are made of rubber, which reduces the noise caused by the collision between the buffer plates and between the buffer plate and the inner wall of the buffer cavity.

[0012] Figure 2 This is a cross-sectional view of the present invention.
[0013] In the diagram: 1. Main body; 2. Buffer cavity; 3. Buffer plate; 4. Guide post; 5. Elastic plate; 6. Elastic gasket. Detailed Implementation
[0014] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0015] Example: A punch press slide, such as Figure 1 , Figure 2 As shown, the machine includes a main body 1 with flange holes and bolt holes for installation, allowing it to connect with other parts of the press and the upper die. A buffer cavity 2 is provided inside the main body 1, containing several buffer plates 3. The buffer plates 3 can move vertically relative to the main body 1. When the upper die contacts the workpiece, the workpiece exerts an upward force on the main body 1 through the upper die, slowing the descent of the main body 1. At this time, the buffer plates 3, under inertia, exert a downward force on the main body 1, reducing the rebound tendency of the main body 1 and ensuring the impact force of the stamping, thus ensuring a smooth stamping process. A guide post 4 is fixedly connected between the inner bottom and inner top surfaces of the buffer cavity 2. The buffer plates 3 are fitted onto the guide post 4 and are slidably connected to the guide post 4. The buffer plates 3 are perforated circular plates. The guide post 4 reduces the horizontal displacement of the buffer plates 3. The radius of the buffer cavity 2 is larger than the radius of the buffer plates 3. The buffer plates 3 are limited by the guide post 4, preventing them from contacting the buffer cavity 2 during movement and thus reducing their kinetic energy.
[0016] like Figure 1 , Figure 2 As shown, an elastic sheet 5 is provided between adjacent buffer sheets 3. The thickness of the elastic sheet 5 is less than the thickness of the buffer sheet 3. The inner top and inner bottom surfaces of the buffer cavity 2 are provided with elastic pads 6 coaxial with the guide post 4. The radius of the elastic pad 6 is greater than the radius of the buffer sheet 3. Both the elastic sheet 5 and the elastic pad 6 are made of rubber. Rubber has good shock absorption and noise reduction functions, reducing the noise generated by the collision between buffer sheets 3 and between buffer sheets 3 and the inner wall of the buffer cavity 2. The thinner thickness of the elastic sheet 5 shortens the process of the impact being transmitted downward from the deceleration of the main body 1 to the buffer sheet 3. The elastic pad 6 is fixed to the inner top and inner bottom surfaces of the buffer cavity 2 by adhesive bonding. The contact between the elastic pad 6 and the buffer sheet 3 is ensured by increasing the radius of the elastic pad 6.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
