Description

Technical Field

[0001] This application relates to the field of busbar processing technology, and in particular to a floating die structure for a busbar punching machine. Background Technology

[0002] The current busbar processing requires punching, which is mainly done using a punching machine. When using a punching machine, the punch generates a downward force of up to 30 tons with each press. Over time, the ball bearing guides bear this impact force, leading to damage to the ball bearing guide structure. Damaged ball bearing guides affect the processing accuracy of the punching machine, ultimately causing equipment failure.

[0003] The information disclosed in the background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that such information constitutes prior art known to those skilled in the art.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can typically be arranged and designed in various different configurations.

[0017] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0018] Technical means not detailed in this application and not used to solve the technical problems of this application are all set according to common general knowledge in the field, and multiple common general knowledge setting methods can be implemented.

[0019] The structure provided in this application is installed on existing commonly used busbar punching and / or shearing machines, such as the CKJ30S CNC busbar automatic punching machine. The structure of other components of the punching machine is the same as that of existing punching machines, and will not be described in detail here.

[0020] See Figure 1 The floating die structure of the busbar punching machine provided in this application has a mounting hole 131 in the central area of ​​the die base 1, which houses the die sleeve 13. A stepped groove 132 is provided above the mounting hole 131, and the width of the stepped groove 132 is greater than the width of the mounting hole 131. A mounting ring is provided at the top of the die sleeve 13. A gap 141 is provided between the mounting ring and the inner wall of the stepped groove 132. Multiple elastic material buffers 14 are provided in the gap 141. Ball bearing guides 221 are symmetrically arranged on the outer side of the pad 231. The pad 231 and the guide mounting plate 22 are mounted on the top surface of the base plate 3.

[0021] A buffer gap 133 is provided between the bottom surface of the die sleeve 13 and the pad block 231. When the busbar 12 placed on the die sleeve 13 is pressed down by the upper punch 11, the busbar 12 is inserted into the die cavity 211, forming a punch on the busbar 12. At the same time, the downward pressure pushes the die sleeve 13, which is connected to the outer wall of the die cavity 211, down. At this time, the die sleeve 13 presses down and squeezes the elastic material buffer 14. The bottom of the die sleeve 13 presses down on the pad block 231 simultaneously, thereby effectively dispersing and buffering the downward pressure of the punch, avoiding direct impact on the ball guide rail 221 and causing damage to the ball guide rail 221. The die sleeve 13 is set to move up and down reciprocally within the mounting hole 131, and squeezes the elastic material buffer 14 each time it presses down to punch.

[0022] In one specific embodiment, elastic material buffer members 14 are spaced apart and filled within the gap 141.

[0023] In one specific embodiment, a discharge hole 21 is provided in the central area of ​​the pad block 231 and the base plate 3 so that the punching waste of the busbar 12 falling from the die 211 can be discharged.

[0024] In one specific embodiment, the die sleeve 13 is provided below the die cavity 211 and is connected to the die cavity 211 and the central discharge hole 21 of the pad block 231, thereby realizing the directional and timely discharge of punching waste.

[0025] In one specific embodiment, the elastic material buffer 14 is a polyurethane buffer strip or a natural rubber buffer strip.

[0026] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
