extension spring 

The tension spring generates tension and bears the load through axial stretching. It is also called a tension spring, or simply a tension spring. Tension springs are generally manufactured from steel wires with circular sections. When space is limited, they can also be produced with flat section steel wires. When not subjected to tensile load, the coils of the tension spring are generally close together. At this time, there is a certain internal stress between the tightly closed spring wires, which is technically called primary tension. The initial pulling force can be freely adjusted during production, but the maximum value is determined by the material, pitch diameter and thread diameter. nbsp;

Extended categories: British hook tension springs, German hook tension springs, movable hook tension springs, side lug tension springs, semicircular hook tension springs, non-hook tension springs, Drawbar tension springs. Application areas: Tension springs are the * commonly used spring types by customers, and they are used in al* all industrial fields.

Catalog's tension springs mainly serve six major industries including mechanical automation, packaging and filling, medical equipment, electronics, power transmission and auto parts.

 Common production equipment for Catalog springs 

Compression spring production equipment 

Catalog Company has nearly 20 computer spring presses of various types, covering the wire diameter range of 0.08-10.00mm. These equipment can be used to produce various types of compression springs, tower springs, square wire springs, circlip springs and wave springs. Compression spring production equipment Spring equipment Tension spring torsion spring production equipment Katarot Company has 9 computer universal machines and wire straightening and punching machines, covering the wire diameter range of 0.15-6.00mm. These equipment can be used to produce various types of tension springs, torsion springs, wire forming and flat coil top wave springs, etc. nbsp;

tooling die

Precise elasticity and guaranteed life 

Based on Cataro's existing computer universal machine and equipped with customized punching heads and curling heads, these equipment can complete operations such as punching, bending and curling of leaf springs and spring shells. nbsp;

Spring end grinding equipment

 Spring grinding is an important auxiliary process in spring production. The amount of grinding and the verticality of the spring grinding will directly affect the mechanical properties of the spring. Cataro has 8 spring grinding machines of various types, with a spring grinding wire diameter of 0.5-20 mm. In particular, our computer spring grinding machine has segmented pressing and grinding wheel compensation functions, which can control the length tolerance of the spring after spring grinding. Within 0.1 mm. nbsp;

 Tempering workshop heat treatment equipment 

The heat treatment furnace is a key equipment in spring production, which directly affects the stability and consistency of the spring! The heat treatment furnaces in Kataro are divided into two categories: the crawler tempering furnace is used to temper springs at medium to low temperatures below 500℃, and the 3-meter-long furnace space can be divided into three sections for temperature control and monitoring. The maximum temperature of the box-type muffle furnace can reach 1200 ° C, and multiple heating curves can be freely set to meet the high temperature heat treatment requirements of special alloy springs. Both types of heat treatment furnaces in Cataro have heating curve recording and exporting functions to facilitate process control and data traceability for important projects.

 Spring shot blasting and pre-pressing equipment 

Catalog also has some auxiliary equipment for spring production, which can strengthen and improve certain aspects of spring performance. For example, spring shot blasting equipment can hit the spring surface at high speed by stainless steel pellets with a diameter of 0.3-0.4mm, which can produce a prefabricated compressive stress layer, which increases the service life of the spring by 3-10 times; at the same time, it can also eliminate the spring surface. Fine burrs and surface defects. The automatic spring prepress customized by Catalog Company can automatically prepress springs with certain overstress in design, stabilize the free length and force value of the spring, and also have certain benefits for extending the service life. nbsp;
