Description

Technical Field

[0001] The utility model relates to the technical field of upsetting, and specifically discloses a linking sheet upsetting mechanism. Background Art

[0002] like Figure 1 The new energy link plate shown needs to be thinned at position A after being bent and formed in order to meet the needs of later use. The method used in the prior art is generally cutting, which has slow working efficiency and high processing cost. In order to solve this problem, the present application discloses a link plate thinning mechanism. Utility Model Content

[0003] In order to overcome the deficiencies of the prior art, the utility model discloses a linking piece upsetting mechanism.

[0004] To achieve the above-mentioned purpose, the utility model is implemented through the following technical solutions: a link plate thinning mechanism, including a lower die pad, a pressure block and an upsetting punch, the upsetting punch can be axially raised and lowered through the pressure block, the bottom of the pressure block is formed with a limiting structure for preventing the link plate from deforming, and the limiting structure includes a plurality of limiting blocks arranged on the periphery of the contact part between the link plate and the lower die pad.

[0005] It is further preferred that the cross-section of the upset punch is one of a circular, square, diamond or trapezoidal structure.

[0006] Further preferably, a through slot having the same cross-sectional shape as the upsetting punch is vertically opened at the inner center of the pressing block, and the upsetting punch can be axially raised and lowered through the through slot.

[0007] The utility model achieves the following beneficial effects:

[0008] The present application thins the corresponding position of the link sheet by upsetting instead of cutting while ensuring that the link sheet does not deform, which not only improves work efficiency but also reduces production costs and has strong use value.

[0009] Other features and advantages of the utility model will be described in the following description, and partly become apparent from the description, or understood by implementing the utility model. The purpose and other advantages of the utility model can be realized and obtained through the structures indicated in the description and the drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0016] In the description of the present invention, it should be understood that terms such as "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0017] Example

[0018] In order to solve the problem of cutting Figure 1 The A position 51 of the link sheet 50 shown in the figure is thinned, which has the problems of low working efficiency and high cost. Figure 2 and Figure 3 As shown, the present application discloses a thinning mechanism for a linking piece 50, including a lower die pad 10, a pressure block 20 and an upsetting punch 30. The upsetting punch 30 can be axially raised and lowered through the pressure block 20, and a limiting structure 40 is formed at the bottom of the pressure block 20 for preventing the linking piece 50 from deforming.

[0019] When the link sheet 50 is subjected to upsetting processing, the bent link sheet 50 is first placed on the lower die pad 10, and the pressing block 20 is first used to press the link sheet 50, and then the upsetting punch 30 is passed through the pressing block 20 to apply pressure to the link sheet 50. After that, a thinned groove will appear at position A 51 of the link sheet 50. In addition, the side of the link sheet 50 can be limited by the limiting structure 40 cooperating with the pressing block 20. When the upsetting punch 30 is upsetting, the link sheet 50 will not be deformed, thereby ensuring the quality of the product after upsetting.

[0020] In one specific embodiment, the limiting structure 40 includes a plurality of limiting blocks 41 disposed on the periphery of the contact portion between the linking piece 50 and the lower mold cushion block 10 .

[0021] An option of the present application is that the cross-section of the upsetting punch 30 of the present application is one of circular, square, diamond or trapezoidal structures. During the specific implementation, if personnel in this technical field need to use an upsetting punch 30 of other shapes for upsetting processing, it can also be adaptively selected.

[0022] In order to enable the upsetting punch 30 to pass through the pressing block 20 to perform upsetting processing on the linking plate 50, the present application vertically opens a through groove 21 consistent with the cross-sectional shape of the upsetting punch 30 in the inner center of the pressing block 20, and the upsetting punch 30 can be axially raised and lowered through the through groove 21.

[0023] In the description of this specification, the description with reference to the terms "one embodiment", "example", "specific example", etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0024] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable technicians familiar with the technical field to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
