Description

TECHNICAL FIELD

[0001] The utility model relates to a spring pre-pressing machine and belongs to the spring processing field. BACKGROUND

[0002] A spring is a mechanical part that works by using elasticity. The part made of elastic material deforms under the action of external force and returns to the original state after the external force is removed. In the production process of the spring, the spring elasticity before pressing cannot meet the use requirements, and the spring pre-pressing machine is needed to press the spring to the appropriate size. Pre-pressing is an important step in the spring manufacturing process. Pre-pressing refers to applying a certain static load to the model of the spring to improve the carrying capacity of the spring and reduce the settlement of the spring under load. The pre-pressing method is to compact the spring and then remove the load.

[0003] The spring pre-pressing machine is a device for pre-pressing impact load on the spring formed by cold coiling.

[0004] The existing application number is 201621347156.8, and the patent application name is a spring pre-pressing machine. It is disclosed that the spring pre-pressing machine includes a rotary table feeding mechanism, a pre-pressing mechanism, and a controller. The rotary table feeding mechanism includes a bearing table, a feeding rotary table installed above the bearing table, a plurality of bushings for placing springs uniformly distributed around the edge of the feeding rotary table, and a first driving device connected with the feeding rotary table and driving the feeding rotary table to rotate. The pre-pressing mechanism includes a gantry installed on the bearing table above the feeding rotary table, a pre-pressing die installed on the gantry and abutting the upper surface of the rotary table, and a second driving device connected with the pre-pressing die and driving the pre-pressing die to move up and down perpendicular to the bearing table. The feeding rotary table and the pre-pressing die are controlled by the controller connected to the first driving device and the second driving device to perform coordinated motion, and the spring is pre-pressed. The pre-pressing effect of the spring is better, the burden of the worker is reduced, and the labor cost is reduced.

[0005] However, the above-mentioned device still has the following problems: the time required for spring pre-pressing is not fixed and is affected by many factors, and the feeding rotary table for placing materials can only place materials at the edge. Although automation is achieved and the burden of workers is reduced, the production efficiency is not high. For springs that need to be pre-pressed for more than ten minutes, the device is always operating, which consumes a lot of energy.

[0006] Therefore, the utility model provides a semi-automatic spring pre-pressing machine for pre-pressing a large number of springs. UTILITY MODEL CONTENTS
