Cutting device

Abstract

The invention discloses a cutting device. The cutting device comprises a supporting body (8) which is fixedly provided with a housing (9). A cutting tool rod (7) is slidably mounted on the supporting body (8). The cutting tool rod (7) comprises a cutting tool bit (72), a notch (71), a right-side protruding portion (76), a left-side protruding portion (75) and a jointing end (77), wherein the cutting tool bit (72) is located at the left end of the cutting tool rod (7) and used for executing cutting; the notch (71) is formed in the upper side face of the cutting tool rod (7); the right-side protruding portion (76) and the left-side protruding portion (75) are located on the lower side face of the cutting tool rod (7); and the jointing end (77) is located at the right end of the cutting tool rod (7) and used for being jointed with the housing (9). The jointing end (77) is further jointed with an elastic bracing-and-pressing part (770), so that the jointing end (77) of the cutting tool rod (7) can lean on the housing (9) in an asymmetrically-pressing manner. A wedge-shaped plate (73) is arranged in the supporting body (8) in the manner of corresponding to the notch (71), wherein the wedge-shaped plate (73) can slide up and down and is braced and pressed towards the cutting tool rod (7) by an elastic bracing-and-pressing spring (74).

Description

technical field [0001] The invention relates to a material processing device, in particular to a cutting device, such as a cutting device for soft materials. Background technique [0002] Cutting devices are widely used in the field of material processing. The cutting device often adopts the reciprocating motion of the blade to complete the cutting of the material. [0003] However, during the cutting process, the cut material often leaves weak residual connection parts after the cutting is completed. This has a detrimental effect on the processing quality as well as on subsequent processing steps. Especially for cutting soft materials with a certain degree of elasticity, it is not easy to completely cut off the material due to the slow movement of the blade at a small position, resulting in material residues. [0004] However, if simply adding equipment performance to the cutting device, such as increasing the running speed and cutting force of the blade, this will signi...

Problems solved by technology

[0003] However, during the cutting process, the cut material often leaves a weak residual connection after the cutting is completed.

This adversely affects the processing quality as well as subsequent processing steps

Especially for cutting soft materials with a certain degree of elasticity, it is not easy to completely cut off the material due to the slow movement of the blade at a small position, resulting in residual material

[0004] However, if the equipment performance is simply increased to the cutting device, such as increasing the operating speed and cutting force of the blade, this will significantly increase the cost and increase the complexity of the equipment, which is not conducive to maintenance
