How to make quality wire nails?
Try to choose the nail making machine from famous and good reputation manufacturers. Usually large-scale and powerful nail machine manufacturers, they have the leading technology, good quality of automatic nail machine,can ensure the quality of nail machine, and after-sales service is relatively perfect.
When purchasing a fully automatic nail making machine, it is better to visit the factory in person. so that they can intuitively understand the production status of the manufacturer of the nail making machine, and at the same time, they can observe the quality of the nail making machine with their own eyes.
The manufacture of large and small iron nails for woodworking is done by making a roll of low carbon steel wire with a diameter equal to the diameter of the iron nail through the following process actions.
1) Straighten steel wire. And intermittently transported to the clamping station according to the rhythm requirements.
2) Cold pier to form the nail cap, before this, clamping the steel wire.
3) Cold squeeze the nail tip.
4) Cut the wire.
Raw data and design requirements of making nails:
1) Diameter of nails Φ 1.2 – 6.5 mm.
2) The nail length is 10- 200 mm.
3) Productivity of 160-450 pieces /min.
4) Maximum cold pier force 3000N, maximum shear force 2500N.
5) The mass of the cold pier slider is 8kg, and the mass and moment of inertia of other components are not included.
6) It requires compact structure, excellent transmission performance and minimum noise.
Finally, communication more with the manufacturer’s technical person, in order to buy the ideal nail machine.
Finished nails storage :
After the nail machine produces finished nails, if the storage method is not proper, the nails will easy get rusty. How to make the nails durable? There are two commonly used storage methods:
1. After the nails are made, make it polished.
The equipment used is: the polishing machine,firstly add sawdust and paraffin, and then pours the nails into the polishing drum. The polishing machine adopts a drum design. Under the action of friction, the nails, sawdust and paraffin can remove rust and increase the nail brightness. A protective layer is formed on the nail surface, so that the nails are not only bright but also resistant to storage. The cost of nail polishing treatment is low, which is one of the most economical and practical methods.
2. Galvanize the nails
After the nail is made and formed, make it galvanized. After galvanizing, a protective layer will be formed on the surface of the nail, which not only improves the appearance quality of the nail, but also improves the high temperature resistance and corrosion resistance. The methods of galvanizing nails include electroplating and hot-dip galvanizing. The equipment requires galvanizing equipment and various chemicals. The nails are placed in the electroplating solution, or they are tightly connected together by electric current. Or combine it with the nail surface by relevant physical and chemical methods, resulting in a good coating. This coating can improve the strength of nails, so it is favored by many manufacturers.
Nail galvanizing equipment can not only be used for galvanizing nails, but also can be used for galvanizing various metal products, such as: iron wire, threaded nails , insulation nails, corrugated nails, bolts, etc., but the nail galvanizing treatment equipment has certain pollution, and it is related to the output and site, and the investment cost is bigger than that of the polishing treatment equipment.
What are the common types of wire drawing machines?
Definition of wire drawing machine: A machine that draws wire rods to smaller diameter wire. Classification of wire drawing machines: large-scale continuous-tank wire-drawing machines, dry pully wire drawing machines, large-water tank wire-drawing machines, and small water-tank wire-drawing machines.
The old-fashioned pulley wire drawing machine is the main type, and there are also double reel type, straight type, looper type, tuning roller linear type, combined type and various water tank wire drawing machines coexist. The pulley wire drawing machine is a non-slip dry continuous wire drawing machine that can be integrated; during the drawing process, the wire and the surface of the reel do not slide relative to the circumferential direction of the reel, and the surface wear of the two is relative. It is relatively small, and when a reel in the middle is temporarily stopped, the reels behind it can still work as usual for a period of time depending on their respective accumulated line quantities. This model has the advantages of simple structure, convenient operation and maintenance, and low manufacturing cost.
Nail making machine workshop’s requirements:
The requirements for the workshop in the production of nail are also very important. The production line nail making equipment can produce F nails, T nails, K nails, N nails, J nails and other models and specifications of different specifications. Requirements for the production site of air nailing and nailing machine equipment:
The workshop needs more than 2.5 meters high, more than 22 meters long, and more than 6 meters wide (installed side by side)
The above workspace includes raw material storage, from production equipment to finished product, sorting, packaging, storage.
How to solve the nail cap problems during nail making?
1. If there is no nail cap:
This is a common fault, Most of it is the reason why the clamp cannot clamp the nail wire tightly. You only need to replace the clamp;
There is another possibility that the nail wire is reserved for punching the nail cap. If it is too short, you can adjust the length of the reserved nail wire.
Also check if the wire diameter is smaller than the nail die size.
2, If the nail cap is not round:
This fault is usually also on the fixture. Firstly, observe whether the countersunk hole on the fixture is round. If it is not round, it needs to be re-drilled; it is also necessary to observe whether the die hole of the fixture is uneven, and adjust it to ensure smooth.
There is also a problem with the nail wire, either the nail wire reserved for punching the nail cap is too short, adjust the length of the reserved nail wire; or the nail wire is too hard to punch the nail cap or the nail cap is unqualified , the nail wire needs to be annealed.
3, The thickness of the nail cap:
It is also necessary to check the fixture to see whether the height of the two sets of fixtures is the same, and also to see whether the fixture can clamp the nail wire, and then observe whether the countersink hole of the fixture has serious wear on one side. In the end, it is necessary to observe whether the nail wire is too hard and the nail cap punched out is unqualified.
4, The nail cap is skewed:
first, check whether the center of the two nail knives is consistent with the center of the nail mold, whether the front and rear heights of the nail knives are neat, and whether the counterbore positions of the two nail molds are on the same plane, and finally check the mold. Whether the shell is loose.
Daily maintenance of nail making machine:
1. Do not adjust the machine while it is working.
2. Keep the machine clean and tidy, the nail molds should be cleaned frequently, and do not use rusty wire to make nails.
3. After starting, wait for the machine to run normally before pulling the wire feed handle to feed the wire nails. When stop the machine, stop feeding the wire first.
4, Grind the nail cutter and keep the it sharp.
5. During the operation of the machine, attention should be paid to the temperature rise change of each friction part and the occurrence of abnormal noise.
6. Disconnect the power first when repairing equipment or electrical appliances.
7. The equipment that needs to be replaced shall use the original specifications.
8. Regularly inject oil and lubricate to ensure that each lubricating part is well lubricated. When the new machine is used, it is best to carry out a large amount of lubrication within 15 days.
9. Do not drive without removing the protective cover.
