The manufacturing process of the connection type spring core mattress

Author: Synwin–Mattress Manufacturer

Foshan Mattress Factory introduced that the connecting spring core is based on the size of the bed core of various specifications, and the concave spring is connected by a spiral spring and a surrounding steel to form an elastic whole. This not only increases the strength of the bed core, but also makes all the bed cores form a whole spring cushion spring core Foshan Mattress Factory recommends that the manufacturing process of the connected spring core is as follows: Machine threading (hand threading) - adding support Force spring - edge steel - air gun - bed core inspection - loading - dressing (1) Spring threading Foshan Mattress Factory has experienced that threading the spring is the process of connecting the coil springs in the spring mattress into a whole. The threading spring is wound with 70 carbon steel with a diameter of 1.2-1.6mm, and the diameter of the coiled spring is slightly larger than the diameter of the threading spring, and the gap is within 2mm.

When winding the through spring, the upper and lower circles of the adjacent coil springs in the spring cushion are respectively connected in a criss-cross manner to form the cushion spring core. Then use wire pliers to bend both ends of the spring wire to tighten the spring coil. Simple, fast, and solid.

Before wearing the spring, first calculate the number of rows of springs and the number of springs in each row according to the specifications of the mat. The form of placement is usually horizontally one by one next to each other, and vertically (the long direction of the mat) is lined up at regular intervals, and the interval between rows is usually 60mm. The clear space between adjacent springs in the width direction and the length direction needs to be less than 40mm, or they are tightly connected.

(2) Add support spring The support spring is a kind of support spring, which is a double spring added to the edge of the bed core to prevent the mattress from sinking nearby after long-term use. Foshan mattress factory support spring can increase the bearing capacity and durability of the entire bed core. It is usually used in the center of the outermost circle of the spring core of the cushion, especially the four corners of the spring core.

Usually, a support spring is added every 2 to 5 general springs. (3) Edge-cutting steel Foshan Mattress Factory uses steel wires with a diameter of 3.5 to 5 mm, which are cut with a regulating machine (cutting steel wire) according to the required size around the mattress, and then bent by an automatic bending machine according to the shape of the spring bed core. Fold the wire ring to make it fit with the tension spring around the tension spring core, and then weld the steel wire into the edge steel through the frame steel wire butt welding machine. The contact points of the upper and lower circles of each spring around the spring core can be firmly established. (4) Loading In order to avoid the deformation of the spring core after long-term use, each bed core of Foshan Mattress Factory must be preloaded and shaped by a leveling machine for many times to eliminate the residual deformation of the spring and make the mattress durable. After finishing, the bed core will not sag, the fabric will not slacken, and the cushion will be flat and stretched for a long time.
