Description

Technical Field

[0001] This utility model relates to the field of conductive copper plate stamping, and in particular to an automatic feeding mechanism for copper plate stamping. Background Technology

[0002] In the existing stamping process, after the die stamping is completed, the material strip needs to be manually pulled to load the material. This loading method requires a high level of worker skill. Because the alignment accuracy between the material strip and the stamping die is low when manually pulling the material strip, there are problems such as low material utilization and waste. In addition, the manual loading method is not conducive to protecting the safety of workers. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the purpose of this utility model is to provide an automatic feeding mechanism for copper plate stamping to achieve the purpose of automated feeding.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] An automatic feeding mechanism for copper plate stamping includes a feeding platform on the side of the stamping machine for feeding sheet metal to the stamping machine. The feeding platform is characterized by having a stepping feeding mechanism that is linked to the stamping machine and synchronously feeds the sheet metal to the stamping machine through the feeding platform.

[0006] In a preferred embodiment of the present invention, the stepping feeding mechanism includes a transmission plate connected to the stamping machine and moving up and down with the opening and closing of the stamping machine; a stepping guide rail disposed on the side; and a feeding clamp that pushes the material sheet forward with the opening and closing of the stamping machine under the guidance of the stepping guide rail.

[0007] In a preferred embodiment of this utility model, the stepping guide rail is provided with a curved stepping guide groove. The stepping guide groove has a second end located near the side of the press and a second end located away from the side of the press, so that the feeding clamp moves forward when it rises under the drive of the transmission plate and moves backward when the transmission plate falls down.

[0008] In a preferred embodiment of the present invention, the feeding clamp is provided with a limiting member to restrict the material sheet from moving backward relative to the feeding clamp.

[0009] In a preferred embodiment of the present invention, the limiting member includes a limiting pin that directly contacts the sheet material. The limiting pin has an inclined structure located on the side away from the press, thereby restricting the loading clamp from moving backward relative to the sheet material.

[0010] In a preferred embodiment of the present invention, the limiting member further includes a spring-loaded structure that supports the limiting pin to extend outward.

[0011] In a preferred embodiment of the present invention, the stepping feeding mechanism further includes a sliding guide rail arranged between the feeding platform and the feeding clamp.

[0012] The beneficial effects of this utility model are as follows:

[0013] The automatic feeding mechanism for copper plate stamping provided by this utility model is a slider-type automatic stepping feeding mechanism set on one side of the feeding table. The feature of the stepping guide rail inclined groove enables the feeding clamp to drive the material sheet to be automatically fed in accordance with the stamping machine cycle.

[0018] In the description of this utility model, it should be noted that the terms "upper", "lower", "left", "right", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. The above description is for the purpose of simplifying the description of this utility model and does not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0019] Unless otherwise specified, the singular forms “a,” “the,” and “the” used in this specification include the plural forms. The terms “comprising,” “including,” and “containing” used in this specification indicate the presence of the claimed feature, but do not exclude the presence of one or more other features.

[0020] When a component is described in the specification as being "on", "fixed" to, "connected" to, or "joined" to another component, the component may be directly located on, fixed to, connected to, joined to, or in contact with the other component, or there may be an intermediate component present.

[0021] Exemplary embodiments of this application will now be described with reference to the accompanying drawings. However, it should be understood that this application can be presented in many different ways and is not limited to the embodiments described below. It should also be understood that the embodiments disclosed herein can be combined in various ways to provide further additional embodiments. Throughout the drawings, the same reference numerals denote the same or functionally identical elements.

[0022] Figure 1 The overall structure of this automatic feeding mechanism for copper plate stamping is shown, mainly including a feeding table 30 located on the side of the stamping machine 20 for feeding the sheet metal 10 into the stamping machine 20 for processing. In order to achieve automatic feeding, a stepping feeding mechanism 40 is provided on the feeding table 30, which works synchronously with the opening and closing of the stamping machine 20.

[0023] Figure 2 and Figure 3 The structure of the stepping feeding mechanism is shown. A pair of stepping guide rails 41 on the side of the stepping feeding mechanism 40 are placed on both sides of the feeding table 30. The feeding clamp 44 is placed on the feeding table 30 and connected to the stepping guide rails 41 on both sides. The top of the stepping guide rails 41 is connected to the stamping machine 20 through a transmission plate 46, so that it moves up and down with the opening and closing of the stamping machine 20. A stepping guide groove 42 is provided on the stepping guide rail 41. The stepping guide groove 42 is curved, and its second end 42b is located on the side closer to the stamping machine 20 relative to the first end 24a. The feeding clamp 44 is hinged in the stepping guide groove 42 by a pin, so that when the stepping guide rail 41 undergoes vertical displacement, it drives the feeding clamp 44 to move forward and backward along the stepping guide groove 42 on the feeding table 30.

[0024] A limiting component is arranged inside the feeding clamp 44. This component includes a limiting pin 47 and a spring-loaded structure 47b for keeping the limiting pin 47 elastically extended towards the feeding table 30. A plurality of small holes 11 are spaced apart on the sheet material 10. Preferably, the spacing is a pre-reserved distance for each stamping process. To allow the limiting pin 47 to engage with the sheet material 10, the side of the limiting pin 47 away from the press 20 is a sloped structure, thus restricting the sheet material 10 to only move forward relative to the limiting pin 47. When the press 20 is open and feeding is required, the limiting pin 47 engages with the small hole 11, and the displacement of the stepping guide rail 41 moves the sheet material 10 forward. When the press 20 is closed, the stepping guide rail 41 moves the feeding clamp 44 backward, and the limiting pin 47 engages with the next small hole 11.

[0025] In one embodiment, a sliding guide rail 43 is provided between the loading clamp 44 and the loading platform 30 to guide the loading clamp 44 to slide smoothly.
