Lock former machines

Types of Lock Former Machines

The Lock former machines are used to make special type of joints known as "lock seams" for the HVAC ducts. Generally, these joints are complex designs which consist of an external flange, a hooked internal flange, and a groove. Lock seam machines can manufacture the lock seam type joints on the edges of the ducts with the help of using rolls and formers.

Based on the working principle and ease of use, the lock former machines can be categorized into the following three types:

• Manual Lock former Machine

This machine comes with a foot pedal that manual operates the lock forming process. The operator puts the metal into the machine and then pushes the pedal with their foot to start forming the lock. Manual machines are smaller, lighter, and easier to move around than electric ones. However, they make it harder to use just because the locks need to be made by hand.

• Electric Lock Former Machine

For handling various forms of metal sheets that may be used in the production of ducts, the electrically operated lock former machine proves to be a very helpful piece of equipment. Users can run the machine at their convenience without having to stop for rest periods or delays, thereby increasing output and efficiency. An electric motor used to drive this model provides the entire machine and its production capabilities with minimal operational and maintenance costs. It also ensures a constant low production cost per item. Operation and control are easy and fast, and the degree of server's skill required is also low, as the server knows how to run the controls easily and understand what's going on through the easy-to-read displays.

• Pneumatic Lock Former Machine

Pneumatic lock former machines are more effective and faster than manual ones. They're powered by air, which drives the pounding and locking process. Because of this, production speeds are much higher than with manual machines. Aside from being faster, they pretty much make the operator's job easier to do and cut down on the amount of work and time that goes into making locks. With their high production rate, pneumatic lock former machines let users produce a lot more pieces in less time.

Specifications and maintenance of lock former machines

The following are specifications that buyers need to familiarize themselves with before investing in a lock seam machine:

• Material thickness: The material thickness is usually described as guage or mm. Vaires by manufacturer and capable of handling aluminum stainless steel, galvanized steel, copper or other metals with a thickness ranging from thin gauge steel to over"> lock former machines can process materials with particular thicknesses.
• Operation speed: Machine's working pace is generally measured in meters per minute or feet per minute and can range from up production lines. The transformation speed indicates how quickly machine can make lock seams. Higher operating speeds mean lock former machines can produce seams faster, which increases efficiency.
• Seam Types: Lock former machines are made to create a variety kinds of seams. The double lock seam, the single lock seam, and others are examples of seam forms. Each kind of seam has distinct characteristics and uses. Depending on the seam types created by the machine, choose a model that is suitable for the requirements and applications.
• Machine sizes: Lengths and widths of lock former machines may vary greatly. Ensure areas and requirements can accommodate the dimensions of lock former machines.

Maintenance

It's crucial to keep the lock seam forming machine in good shape if one wants to produce lock seams more effectively and precisely while extending the machine's lifespan. The main care routines are as follows:

• Regular cleaning: Dirt, grease, and metal shavings accumulated over time should be cleaned off of the entire machine, including its surface, parts, and interiors. Use clean water and neutral detergent to wipe it down. Avoid using corrosive chemical substances to prevent damaging the machine's surfaces and paint layers.
• Lubrication: Lubricate the moving components and gear boxes of the machine frequently with lubricating oil. Lubricating oil can reduce friction, avoid undue wear, and guarantee smooth movement, facilitating the lock seam forming process.
• Fastening parts: Regularly check fasten parts, such as bolts and screws, to ensure they are tightly fastened. In case the fasten parts are loose, they should be fastened again, which helps to improve the stability and precision of the lock seam forming machine.
• Electrical system maintenance: Avoid exposing the electrical system to dampness or water. Periodically, wipe the electrical components carefully to remove any dust and debris. Ensure wires and connections are steady and reliable, and examine electrical parts to see if any damage requires repair.

Usage scenarios of lock former machines

A lock former machine forms and rolls the edges of metal sheets to make a seamless profile. This machine has multiple applications in the HVAC industry and beyond.

• Fabricating boat parts: A hydraulic lock former machine can make staves and gunnels. This machine easily rolls metal sheets into curves, creating smooth shapes needed for the boat's structure.
• Constructing ducts and pipes: The HVAC industry is the largest user of lock seam machines. This is because lock seam machines can create strong pipes and ducts for heating, ventilation, and air conditioning systems. Ducts made using lock former machines have interlocks that resist stretching and provide good airflow.
• Making roofing materials: Standing seam metal roofs have interlocks made with lock seam machines. The interlocks make the roof resistant to harsh weather. Besides, the seams hide the metal panels' edges, reducing the risk of water penetration.
• Shaping curtain rails and coil parts: Curtain coil parts and curtain rails can be made with a lock former machine. This machine is ideal for making parts with interlocks. Lock interlocks provide strong connections between the pieces.
• Creating lock seams: The main use of a lock former machine is to make lock seams on various products. Most seams are strong and provide good support where needed.
• Furnaces and flues: A lock former machine can make the panels used to construct flues and furnaces. The seams formed with this machine are strong enough to withstand high temperatures.
• Making agricultural products: A lock former machine can make strong agricultural products, such as grain bins and chutes. Products made with this machine can resist corrosion and provide long service.

How to choose lock former machines

• Production needs analysis:

  Firstly, it is important to determine the type of product the business will need to produce. Also, consider the production scale and frequency, as well as the material and thickness of the locking profile.

• Machine performance:

  Consider the functions and features of the machine, such as: whether it is equipped with automatic or semi-automatic feeding, locking, and cutting functions; whether it has the ability to process multiple types of profiles; and whether it supports customizing specific machine parameters, etc.

• Machine specifications:

  Choose the proper machine specifications according to the business's production scale and workshop space. This includes determining the size of the machine, as well as weighing system, feeding mode, and locking mechanism.

• Quality and reliability:

  Select a machine that is well-manufactured and reliable in quality. Here, it will help to read reviews of other customers and experience sharing, and to understand the brand's reputation and after-sales service.

• Cost and budget:

  Consider the cost of the machine and ensure it is within the budget. In addition to the purchase cost, one should also consider factors such as installation, debugging, training, and maintenance costs.

• Safety and environmental performance:

  Choose machines that meet safety standards and have appropriate safety devices, such as anti-slip platforms, emergency stop buttons, protective covers, etc. In addition, machines with energy-efficient and environmentally-friendly performance should be preferred to reduce environmental impact.
