How To Make a Spring in Solidworks

Solidworks is at the heart of Sierra Pacific Products and Engineering’s custom part design process. Although we are happy to handle all the modeling ourselves, some of our clients are eager to learn about Solidworks so they can better communicate their ideas and requirements.

If you are interested in learning how to use Solidworks like a pro, we have provided step-by-step instructions on how to make a spring in Solidworks based on the expert knowledge of SPEP engineers’. Learn how to change materials, create threads and much more.

How To Use Solidworks – The Basics (At The Part Level)

Before learning to make a spring, it is helpful to understand a few basics of Solidworks. After mastering these fundamentals, you will be ready to learn more. Whether you want to learn how to make a gear in Solidworks or a complex multi-component device, starting at the beginning is important.

How To Change Units in Solidworks

There are a few unit options in the program. The most significant distinction is between choosing imperial or metric units. These are the options:

• Inch, pound, second
• Millimeter, gram, second
• Centimeter, gram, second
• Meter, kilogram, second

You can switch between them in two ways. To change the unit system for a document, click “Tools” then “Options” then “Document Properties” and select “Units”. You can also change the unit system at the document template level and implement consistently on all new documents.

How To Change Material in Solidworks

Managing your materials in Solidworks is essential for accurately calculating weights for each component or device you are creating in the program. The process for assigning a material to a part is very simple. Just right-click “Material” in the feature manager design tree then “Select Material”. Lastly, select the material you want to use and click “Apply” followed by “Close”.

How To Scale in Solidworks

Scaling is another important element of using Solidworks. In the part document, simply click “Scale” then set the options in the pop-up window. Finally, click the checkmark to finish scaling. Note that scaling is not common at the part level. It’s commonly addressed in the drawing level

Steps for Making a Spring

Now that you are familiar with some of the basics of Solidworks, you are ready to make a spring. The following steps can be used to make an open spring (with rounded ends) or a ground spring (with flat ends).

1. 1. Step 1 – Make a Wire Sketch
      Start by creating a wire sketch on the front plane. Make sketch lines to determine the wire circle location. Set the diameter of the spring per your requirements. Make sure you are setting the center, outside or inside diameter based on your preference. For the open spring, the center line for the spring diameter should connect with the bottom tangent of the wire circle. For the ground spring, it is to the center of the circle.
      
      
   2. Step 2 – Make a Length Sketch
      Create a new sketch on the front plane with a construction line. This line should not be fully defined to help achieve the desired dynamic spring. For an open spring, at the top of the construction line, there should be a perpendicular line that is equal to the inside diameter of the wire circle.
      
      
   3. Step 3 – Implement a Sweep
      • Select the sweep feature. Then, follow these steps for both types of springs:
      • Select “Profile” sketch and “Path” sketch.
      • Select “Profile Twist Value” in the “Profile Twist” drop down menu.
      • Select “Revolutions” from the “Twist Control” drop down menu.
      • Select the preferred rotation direction and number of revolutions per your requirements.
        
        
   4. Step 4 – Create a Parallel Plane
      Now that you have learned how to make threads in Solidworks for your spring, you may want to add flat ends for a ground spring. For an open spring, skip to step seven. Select the second sketch. Create a plane perpendicular to the centerline of the spring. This should be parallel with the top plane. These planes will mark where your ground spring flat ends are cut off.
      
      
   5. Step 5 – Add Top Flat End
      Select the plane at the top of the spring. Then, insert a cut to the material with the SurfaceCut feature. Make sure the direct the cut away from the spring.
      
      
   6. Step 6 – Add Bottom Flat End
      Repeat the same for the bottom flat end. At this point, your ground spring is ready to be inserted into an assembly design.
   7. Step 7 – Insert Into Assembly
      Depending on what you intend to do with your spring design, you can use it in an assembly or just send it to the SPEP engineers. We are happy to work with your part design. Alternatively, we can add other features as you may need.
      
      

How To Render in Solidworks

If you want to show off your design, you may want to create a rendering of the 3D model. To do this, click “Tool” then “Add-ins”. Add PhotoView 360. Start a previous in the graphics area and make whatever changes you need such as scene and decals. Make sure to position and edit the lighting to achieve your desired look. You can also play around with the PhotoView options if you like. Finally, click “PhotoView” then “Final Render” to export a rendering of the part.
