Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of spring bending, in particular to a chuck spring continuous bending device. BACKGROUND

[0002] In the field of chip clamps, springs are often used to compress the chip using the spring force. The elastic properties of the spring can ensure the positioning of the chip without damaging it.

[0003] Chinese patent CN116037734B discloses a spring bending device and method, which includes a base, a fixed clamp fixed to the base, the fixed clamp including a first clamp block and a second clamp block, the first clamp block and the second clamp block being used to fix the spring, the first clamp block and the second clamp block further being provided with matching limiting features for limiting the root of the extension arm to an inclined posture towards a preset direction, a drawing device including a pressing block assembly clamped at a position of the extension arm at a preset distance from the root thereof, and a clamping mechanism for applying a preset pressing force to the pressing block assembly. However, the device still has the following problems during use: Before the spring is bent, a bead hole for easy pressing and an index positioning hole for easy assembly are formed on the spring body, so the blank needs to be cut into pieces in advance. However, the bead hole on the spring will affect the feeding of the spring bending, and after the spring bending of the device is completed, the bent work station is directly extruded by the discharging device. The spring has elasticity, which can easily cause the spring to fly and be damaged during discharging.
