Description

Technical Field

[0001] The utility model relates to the technical field of spring sheet processing, in particular to a spring sheet tail end side rolling device. Background Art

[0002] Shrapnel is a device widely used in shock-absorbing and anti-vibration devices and relay delay devices in the fields of machinery and vehicles. They are usually made of materials such as phosphor bronze and tin bronze. They have the characteristics of being easy to bend in one direction, but have large tensile stiffness and bending stiffness in the other direction. During the processing of shrapnel, the tail end of the shrapnel needs to be rolled sideways to prevent the end of the shrapnel from scratching the human body. The processing of shrapnel mainly uses a stamping die to stamp the tail end of the shrapnel to make it bend and roll sideways.

[0003] Chinese patent publication number CN218108978U proposes a side-rolling device for the tail end of a spring clip. This device works by moving a movable seat downward, linking a movable side pressure block to laterally squeeze the tail end of the spring clip, causing the tail end of the spring clip to bend and deform along a first forming guide groove and a second forming guide groove, bending the originally sharp tail end into an arc structure.

[0004] The above solution has a structural design in which the spring piece is bent and deformed in the first forming guide groove and the second forming guide groove, which easily leads to excessive friction between the spring piece and the inner wall of the groove, causing wear to the spring piece and affecting the quality of the spring piece forming.

[0005] In order to solve the above problems, this application proposes a spring tail end side rolling device. Utility Model Content

[0006] Based on the technical problems existing in the background technology, the utility model proposes a side rolling device for the tail end of a spring.

[0008] A convex block is integrally formed on the bottom edge of the punch head, a bending disk is rotatably mounted on the bottom and convex portion of the punch head, a bending groove is provided on the outer circumference of the bending disk, and a first spring is connected to the side of the punch head and the bending disk;

[0009] A fixing seat is installed on the base, a forming piece is installed on the fixing seat, and the end of the forming piece extends outward to the position below the bending disk, an elastic push roller is installed horizontally on the fixing seat, and the elastic push roller is used to roll the spring sheet on the bottom of the forming piece.

[0010] Preferably, the forming part includes a strip and an arc block, the strip is mounted on a fixing seat, the end of the strip extends to a position below the bending disk and is mounted with an arc block, and the bending groove is adapted to the arc block.

[0011] Preferably, the elastic push roller member includes an elastic part, a movable seat and a roller shaft. The elastic part is laterally inserted into the fixed seat, the movable seat is installed at the end of the elastic part, and an assembly groove is opened at the top edge of the movable seat. The roller shaft is rotatably installed in the assembly groove.

[0012] Preferably, the elastic part includes a movable rod, an end block and a second spring. A through slide is provided in the fixed seat, the movable rod slides through the slide, the movable seat is installed at one end of the movable rod, and an end block is installed at the end of the movable rod away from the movable seat. The second spring is sleeved on the movable rod, and the two ends of the second spring are respectively connected to the fixed seat and the end block.

[0013] Preferably, a guide wheel is installed at one end of the bar away from the arc block, and an electric push rod is installed on the top of the bar. The driving end of the electric push rod is connected to a pull rope, and the pull rope passes around the guide wheel and is connected to the end block.

[0014] The above technical solution of the utility model has the following beneficial technical effects:

[0015] By means of the elastic push roller, the spring piece that needs to be side-rolled can be placed at the end position on the formed part, and then the punch head can be driven by the cylinder to approach the spring piece, so that the bending groove opened in the bending disk can be fitted against the top of the spring piece. When the punch head is pressed down, the bending disk can be rotated, and the tail end of the spring piece can be abutted against the end of the formed part along the bending groove opened in the bending disk, thereby bending the tail end of the spring piece in an arc shape, and then the bottom position of the bent part of the spring piece can be pushed by the elastic push roller to roll on the bottom of the formed part, thereby bending the bottom of the spring piece again, so that the tail end of the spring piece is side-rolled. This structure can reduce the friction between the spring piece and the forming guide groove during the forming process, reduce the wear of the spring piece, and improve the forming quality. At the same time, it avoids the problem of spring piece damage caused by excessive friction in traditional processes, thereby improving processing efficiency and product reliability.
