Description

Technical Field

[0001] The utility model relates to the technical field of cutting and processing of automobile interior decoration parts, in particular to a shape-following cutting device for processing automobile armrest cover. Background Art

[0002] The contemporary population has higher and higher demands and aesthetics for the functions of car interiors, and various seat armrests have been developed for this purpose. During the assembly process of the armrest, it is necessary to ensure that the edge of the fixed face cover has no dimensional interference with the subsequent assembly parts. In order to facilitate the fixing and shaping of the face cover, a longer face cover edge is usually required during the fixing process of the face cover, and this longer face cover edge will cause subsequent assembly interference, which requires the operator to use a handheld utility knife to cut and trim the excess face cover edge that is prone to dimensional interference. The handheld utility knife cutting and trimming face cover edge size process has the advantages of long operation time, inconsistent position status, sometimes requiring secondary trimming, overcutting and scratching risks, and when overcutting and scratching occur, rework is not possible, resulting in product scrapping and increased manufacturing costs. The utility model patent with authorization announcement number CN221136903U discloses a mold for processing automobile interior decoration parts, including a base frame, an L-shaped column is arranged on the top of the base frame, a guide sleeve is arranged on the top surface of the base frame, and an upper mold body for hot pressing the top surface of the cloth is arranged on the top surface of the L-shaped column. The first connecting rod is flipped along the rotating axis by pushing the rod, so that the first connecting rod drives the second connecting rod and the lower hot pressing plate to move vertically and contact the bottom surface of the cloth, and the cloth is hot pressed by the upper hot pressing plate and the lower hot pressing plate. When the cloth is hot pressed, the cutting knife is inserted into the cutting groove when the upper hot pressing plate moves, and then the bottom surface of the movable plate contacts the top surface of the cloth, so that the spring is compressed, and the movable plate and the top surface of the guide sleeve are limited and fixed to the cloth by the spring to prevent the cloth from deflecting. However, the device adopts an integral cutting method to operate, which has high requirements on the quality of the tool, and the tool needs to be replaced as a whole after local damage, and the manufacturing cost is high.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The following further describes the present utility model with reference to the drawings:

[0020] As Figure 1 , Figure 2 and Figure 3 shown, a conforming cutting device for processing the armrest surface cover of an automobile includes a support bottom plate 1. A positioning die 2 is fixedly arranged on the top of the support bottom plate 1 through fasteners. Guiding conforming components 3 are fixedly arranged on the top of the support bottom plate 1, on the left and right sides of the positioning die 2. The guiding conforming component 3 includes a longitudinal guide rail 30 and a guiding groove plate 31 fixedly arranged on the top of the support bottom plate 1 through fasteners. A guiding groove 32 is arranged on the guiding groove plate 31. The shape of the guiding groove 32 is consistent with the cutting route to be cut. During operation, different guiding groove plates 31 are set according to different product cutting shapes, having strong versatility.

[0021] A bidirectional cutting assembly 4 is slidably arranged on the two sets of guide conformal assemblies 3. The face cover to be cut is fixedly mounted on the positioning fetal membrane 2 through a fixing piece. The bidirectional cutting assembly 4 slides along the guide conformal assemblies 3 to cut the face cover to be cut.

[0022] The bidirectional cutting assembly 4 includes a longitudinal slider 40 slidably mounted on the longitudinal guide rail 30, a transverse slider 41 set on the longitudinal slider 40 by fasteners, a transverse support plate 42 fixedly set on the top of the transverse slider 41 by fasteners, a guide cam 43 fixedly set at one end of the transverse support plate 42 by fasteners, a cutting piece 44 fixedly set at the other end of the transverse support plate 42 by fasteners, and an operating handle 45 set on the top of the two cutting pieces 44. The operator can drive the longitudinal slider 40 to slide back and forth along the longitudinal guide rail 30 by operating the handle 45.

[0023] In one embodiment, the transverse slide 41 includes a transverse guide rail fixedly mounted on the top of the longitudinal slide 40 by fasteners and a transverse slide slidably mounted on the transverse guide rail, and the transverse support plate 42 is fixedly mounted on the top of the transverse slide by fasteners. The guide cam 43 is arranged in the guide groove plate 31 and slides along the guide groove 32. When the transverse slide 41 can adapt to the displacement perpendicular to the longitudinal guide rail 30, it can adapt to the curved shape cutting operation.

[0024] The cutting member 44 includes a guide sleeve 440 fixedly mounted on the top of the transverse support plate 42 by fasteners, a knife handle 441 slidably mounted in the guide sleeve 440, a cutting knife 442 fixedly mounted at the bottom of the knife handle 441, a protective cover 443 fixedly mounted at the bottom of the transverse support plate 42 by fasteners, and a reset spring 444 disposed in the protective cover 443.
