Product Description

We are a paramount Toggle Clamps exporter from India. We bring toggle clamps, Mechanical Toggle Clamps, Pneumatic Toggle Clamps etc., which all are available in different shapes and sizes. Durability and reliability are some of the authentications of our products ranging from toggle clamps, mechanical toggle clamps etc. We bring toggle clamps, mechanical toggle clamps etc., at the most pocket friendly price.

Technologically and mechanically advanced, we deal in wide variety of Toggle Clamps which are ideally used for holding the clamp that is used to carry out a piece of work in a stationary condition. Our precision engineered toggle clamps are mainly fixed to a bench or fixture or hand held for holding the work pieces together. Operated on a system of levers and pivots, we provide our customers toggle clamps that move against the work piece, while the linkage of the toggle is stretched or compressed. We also provide locking system in our toggle clamps. Durable enough, it holds the workpiece firmly in its position until the user moves the handle to release the toggle. We also provide action toggle clamps that ensures fast action and put great force in relation with their size and can be used both as push and pull applications.

 

What is a Toggle Clamp?

Toggle clamp is a simple Mechanism, which holds instantly.
The Toggle Clamps Consist of :

  • Handle to operate

  • Clamping arm to reach the work piece

  • Linkages for multiplying the applied force

  • Spindle for pressure adjustment

  • Base for mounting at the workplace

The handle is operated which thereby moves the clamping arm to hold the work piece. A required clamping force is achieved and exerted on the work piece. Under this action the Toggle Clamp Holds the work piece firmly and positively.

Holding Capacity :

The holding capacity mentioned for each clamp refers to the maximum force, which the clamp can withstand after being over-centered without damage to the clamp and without the toggle unlocking due to distortion of the clamp.

The over-center dimension is carefully chosen in relation to the elasticity of the clamp to maximize clamping force while ensuring that the clamp locks closed even under vibration or intermittent loading.

For Hold Down Clamps, holding capacity is measured with the spindle at the farthest end of the clamping arm and will increase as the spindle goes closer to the clamping arm.

Clamping Force :

Clamping Force, the amount of force actually applied to the work piece by closing and locking the clamp, is generally less than the stated holding capacity. Actual clamping force depends on many factors including; spindle position, proper spindle height adjustment, spindle cushioning, work piece material and the clamps mechanical advantage. In most cases, roughly 1/3rd of the stated holding capacity can be applied by hand with medium effort.

 

 

 

Toggle Principle

Toggle action clamps operate through a linkage system of levers and pivots. The fixed length levers, connected by pivot pins supply the action and clamping force. Toggle action has an over centre lock point which is a fixed stop and linkage. Once in the over centre position, the clamp cannot move or unlock unless the linkage is moved. All types of toggle clamps have same action, just oriented differently.

The Toggle Mechanism in a clamp has three functions.

  1. To multiply applied load at the handle into a high clamping force to hold the work piece.

  2. To create an over - centre lock to prevent the clamp from opening & releasing the work piece until opened by the operator.

  3. To rapidly open & close the clamp giving a maximum clearance in which to load & unload the work piece.

 Types of Toggle Actions

This Website contains about 200 different standard toggle clamps & clamping systems. The complete range of these clamps are designed with one of the actions displayed below. Steel-Smith has developed its range of clamps & clamping equipments for infinite applications, considering the different shapes, sizes, holding capacity, operator's position & strength, frequency of operation etc. Most of the Toggle Clamps belong to one of the following five main actions groups, which are

 

1) Vertical Hold Down Action Clamp

    ( VTC Series)

 

2) Horizontal Hold Down Action Clamp

    ( H Series)

 

3) Straight Line Action Clamp

    ( HTC Series)

 

4) Pull Action Clamp

    ( PAH Series)

 

5) Squeeze Action Clamp

    ( TP Series)

 

    ( PAH Series)

 

5) Squeeze Action Clamp

Identification of Clamps

SELECTING THE PROPER CLAMP :

The information contained in this catalogue is designed to select the right clamp for your job. For most of the ordinary applications, consideration Of the following points will lead to the proper selection of clamps:

  • Size & Shape of the parts to be held

  • Uniformity of the part size

  • Holding capacity required

  • Strength & dexterity of the operator

  • Operators suitability

  • Frequency & time cycle of the operation

  • Environmental factors

  • In case of pneumatic clamps cycling time and sequence

For more complicated applications our engineering department as well as our representatives are always ready to make necessary modification in the existing standard range or design something suitable for the job.
