.625 Rectangular Wire Compression Spring

Tuesday, March 20th, 2018

This week’s capability video features a rectangular-wire compression spring , running on our largest CNC….capable of running the largest produced cold-wound wire size; .625″. Rectangular-wire compression springs are typically used in applications that have a higher load requirement than the space allows for, using a round-wire compression spring. Rectangular-wire is more expensive to produce due to raw material, specialized tooling required and longer set-up times therefore when it’s feasible, round wire is recommended.

This week’s capability video features a spring assembly. The assembly includes a .030 music wire spring, a deep-draw stamping, a zinc-plated pin and a lock washer.
The assembly allows the spring to be preset, further relieving spring stress. As a safety feature, the operator must press both paddles with both hands which compresses the spring and allows the washer to secure the internal pin.

Torsion Springs

Torsion springs are helical springs that exert a torque or rotary force and are subject to bending stresses. Torsion springs should always wind up from the free position – never to unwind from the free position. As they wind up, torsion springs reduce in diameter and their length becomes longer. Such springs should be supported over a rod whenever possible. Some spacing should remain between coils to minimize friction which can alter torque and deflection.

The History of Katy Spring- manufacturing rectangular-wire springs.

The History of Katy Spring

The history of companies is built by many short stories; some boring, some not. We’re going to try and tell the not-so-boring ones (in our humble opinion) about Katy Spring & Mfg., Inc.; a company in Katy Texas that started with a conversation that ended something like this; “Why not.”

These are the stories about Katy Spring, small bits of a bigger story that started in 1999. The stories are still unfolding new chapters every day, thanks to our wonderful customers. It’s written for our customers and future customers so that they can get to know our company, our employees, some historical background and philosophy a little better.

The stories are not told in chronological order. This blog is more of a “Readers Digest” about Katy Spring, written in whatever random order they appear. So without further ado, let’s get started with the next read which is titled; “We’ve Always Done it That Way.”

It’s one of the most rewarding things we do in this business; help a customer redesign a spring that truly has a high impact on improving their business in terms of profitability, safety, and in some cases peace of mind. It also takes a lot of courage for a customer to agree change a design and not be satisfied with the status quo that just because “We’ve always done it that way,” doesn’t necessarily mean it’s the best way. Change does involve risk.

There was one customer in particular that has a well-known brand and history in the U.S. who took that very risk to improve their position. Katy Spring was fortunate enough to be asked to take on the project, which we eagerly did, because assisting customers with spring design is one of the best things we do; mainly due to our “three generations of spring maker” knowledge that continues to be past on to current and future Katy Spring employees.

For this particular project, a rectangular-wire compression spring was being used for an application that was for the automotive market. The spring assisted in the braking mechanism so safety was an important factor and concern in moving forward with a design change.

The reason the design change was requested was due to the expense and difficulty involved in manufacturing rectangular-wire springs. The reason rectangular-wire compression springs are generally used in the first place; is when a lot of power is needed in a small space. In this case, the space required was not that small and there was room to use round music wire, a common, readily-available material that requires much less set-up time and run time to manufacture. The original rectangular spring turned out to be overkill in terms of force required and when we worked on a round-wire design, Katy Spring came to the conclusion that round wire will be more than adequate to do the job.

After several months of testing, the new spring design passed inspection and today, is one of this customer’s highest-volume springs used.

Wire forms come in endless varieties of shapes, sizes, and materials. Several materials used to manufacture wire forms include; high carbon spring steel, phosphor-bronze, brass, beryllium-copper, stainless steel, nickel-silver, high-nickel specialty alloys, and non-tempered wire. Wire forming companies such as Katy Spring can bend wire into fabricated shapes such as clips, pins, springs, rings, hooks, and wire racks to name a few.

Torsion spring with lateral legs

Tuesday, March 6th, 2018

This week’s capability video features a torsion spring with lateral legs, made from .062 music wire. This spring is being made on Katy Spring’s CNC wire former, then stress relieved in the in-line oven at 550 degrees F for thirty minutes. The application for this spring is for downhole-oilfield technology.
