Referring to fig. 1 to 3, a connecting spring for a square linear motor capable of vibrating up and down includes a material plate 1; four spring bodies 11 are arranged and stamped on the material plate; each spring body 11 is provided with

fixing parts

1101, 1103 and a vibration buffering part 1102, wherein the two

fixing parts

1101, 1103 are parallel to each other and are correspondingly positioned at two ends of the obliquely arranged vibration buffering part 1102, and an included angle α between the

fixing parts

1101, 1103 and the vibration buffering part 1102 is an obtuse angle; one fixing portion 1101 of each spring body 11 located on the same side is partially connected to the material plate 1 by the scrap 12 (the remainder of the material plate 1 from which the spring bodies 11 are punched), and the other fixing portion 1103 and the vibration damping portion 1102 both extend toward the lower end surface of the material plate.

Specifically, the spring bodies 11 are formed by punching through a progressive punching die, a plurality of spring bodies 11 can be punched in parallel on one flitch according to the area of the flitch 1, part of each punched spring body is still connected to the flitch, and other parts which are not connected to the flitch extend out towards the lower end face of the flitch. The remainder of the blank plate 1, except for the punched spring bodies 11, is the scrap 12, which corresponds to the uniform distribution of the spring bodies 11 inside the scrap 12 in terms of position. Each spring body 11 is stamped into a zigzag structure having two

fixing portions

1101, 1103 and one vibration buffering portion 1102, the

fixing portions

1101, 1103 at both ends are used for correspondingly connecting with the vibrator and the upper and lower cases, while the vertical height of the middle vibration buffering portion 1102 corresponds to the amplitude of vibration of the mover assembly in the case, and the requirements of different mover assembly amplitudes can be correspondingly met by adjusting the vertical heights of the two vibration buffering portions 1102.

The partial connection relation between the two sides of the fixing part 1101 and the waste material is reserved during punching, so that the spring bodies can still be connected with the waste material into a whole, and the function of protecting the spring bodies can be achieved. Preferably, a dummy slit 13 is formed at a position where the spring body fixing portion 1101 is connected to the scrap 12, so that the scrap can be easily removed after the spring body 11 is fixed to a product.
