Description

Technical Field

[0001] The utility model relates to a spring preparation technology and its using equipment. Specifically, it is a spring sheet cutting mechanism with high-precision positioning and preloading flexibility. Background Art

[0002] The spring sheet strip is formed by gear-type pressing and then cut according to the required length to obtain the required spring products.

[0003] At the current stage, the cutting method is that an operator holds the spring sheet strip by hand and uses a cutting tool for cutting. Actually, it is a positioning method for cutting by hand by the operator. This method is affected by the subjective initiative of the operator, unable to guarantee the cutting quality, and there is a certain risk factor in holding the position by hand. In case of improper operation, the operator's finger will be cut and damaged.

[0004] Therefore, it is necessary to provide a spring sheet cutting mechanism with high-precision positioning and preloading flexibility to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a spring sheet cutting mechanism with high-precision positioning and preloading flexibility.

[0006] The utility model realizes the above purpose through the following technical solutions:

[0007] A spring sheet cutting mechanism with high-precision positioning and preloading flexibility includes a cutting platform, and a cutting tool is rotatably arranged at the edge of the cutting platform;

[0008] A flexible pressing module is connected to the cutting tool. The flexible pressing module includes a pressing body elastically arranged, and a sloping pressing positioning slope is arranged on the pressing body;

[0009] As the cutting tool rotates, the flexible pressing contact of the spring sheet strip is preformed on one side of the pressing positioning slope to form a point pre-pressing structure. Then, as the cutting tool continues to rotate, the entire plane of the pressing positioning slope fits to the pressed spring sheet strip to form a high-precision positioning structure with compliant slow pressing.

[0010] Further, the pressing body is connected to a pre-pressing part setting block through an elastic body.

[0011] Further, the elastic body is composed of a number of uniformly arranged compression springs.

[0012] Further, the pre-pressing part setting block is connected to the cutting tool through a pre-pressing rotating shaft.

[0013] Further, an upper anti-rotation positioning plate is arranged on the cutting tool corresponding to the pre-pressing part setting block.

[0014] Further, one end of the cutting tool is rotatably connected to a rotating setting seat arranged on the cutting platform through a rotating shaft.

[0015] Further, a cutting extension handle is provided at the other end of the cutting knife.

[0016] Compared with the prior art, the utility model forms a highly precise and positioned compliant slow pressure by pre-pressing the spring strip at a point position and then pressing and adhering to the entire plane of the pressing positioning slope, ensuring the cutting quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Figure 1 It is one of the structural schematic diagrams of the utility model.

[0018] Figure 2 It is the second structural schematic diagram of the utility model. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Embodiment:

[0020] Refer to Figure 1-2 , this embodiment shows a spring strip cutting mechanism with flexible high-precision positioning pre-pressing, including a cutting platform 1, and a cutting knife 2 is rotatably arranged at the edge of the cutting platform 1;

[0021] A flexible pressing module 3 is connected to the cutting knife 2. The flexible pressing module 3 includes a pressing body 31 arranged elastically, and a pressing positioning slope 32 in a slope shape is arranged on the pressing body 31;

[0022] As the cutting knife 1 rotates, one side of the pressing positioning slope 32 makes flexible pressing contact with the spring strip first, such as making pre-contact positioning pressing at point A to form a point position pre-pressing structure. Then the cutting knife 1 continues to rotate, and the entire plane of the pressing positioning slope 32, the plane formed by point A, point B and other points, adheres to the pressing spring strip accordingly, forming a highly precise positioning structure with compliant slow pressure.

[0023] The pressing body 31 is connected to the pre-pressing part setting block 34 through an elastic body 33.

[0024] The elastic body 33 is composed of a plurality of uniformly arranged compression springs.

[0025] The pre-pressing part setting block 34 is connected to the cutting knife 1 through a pre-pressing rotating shaft 35.

[0026] An upper anti-rotation positioning plate 4 is arranged on the cutting knife 1 corresponding to the pre-pressing part setting block 35.

[0027] One end of the cutting knife 1 is rotatably connected to a rotating setting seat arranged on the cutting platform 1 through a rotating shaft 5.

[0028] A cutting extension handle 6 is provided at the other end of the cutting knife 1.

[0029] Compared with the prior art, the utility model first pre-presses the spring strip at the point positions, and then presses and adheres to the entire plane of the positioning slope, forming a highly precise and compliant slow-pressure positioning to ensure the cutting quality.

[0030] The above are only some embodiments of the utility model. For those of ordinary skill in the art, without departing from the inventive concept of the utility model, several modifications and improvements can still be made, and these all fall within the protection scope of the utility model.
