rivet dismantling method and a dismantling device thereof. The dismantling method firstly places a riveting piece with a failed rivet installed on a die having a blanking hole, and then uses a punch that coincides with the center line of the rivet on the riveting piece to impact the rivet. , the rivet falls into the blanking hole under the impact of the punch to complete the disassembly; the dismantling device includes a concave die for positioning and supporting the riveting piece installed with the failed rivet, and the concave die is provided with a blanking hole; The upper part of the die is provided with a punch for punching the rivet into the blanking hole, and the punch and the center line of the rivet are coincident; Yueluo adopts the punch to dismantle the failed rivet, which not only has high work efficiency, but also has high work strength. It is small, and does not damage the riveting parts on which the rivets are installed; the impact process will not cause the rivets to splash, and the safety is high; and the cost of dismantling equipment is low.

At present, there are mainly the following methods for classifying screws of different lengths mixed together: First, visual identification and manual sorting. This method is time-consuming, labor-intensive and inefficient. Second, the screws are centrifuged and screened according to the quality and size of the screws. However, the quality of screws of the same length is not necessarily the same when the materials of the screws are different. Third, sorting is carried out using a screening device with sieve holes, but the sieve holes are generally simple geometric shapes, which can only roughly distinguish the length of the screws. Moreover, the specific position where the screw falls into the screen hole will also affect the degree of screening. It can be seen that the above-mentioned methods for classifying screws all have the problem of poor effect.

screw is a tool that uses the physical and mathematical principles of the circular rotation and friction of an object to fasten the mechanism of the object step by step. When using screws to fasten objects and parts, it is often necessary to use screws with spring washers and flat washers to lock and fix the relative position, so as to improve the stability of the fastening connection and make the screws less prone to loosening. However, in the prior art, the method of manually inserting the spring washer and the flat washer in sequence is generally used, which not only increases the workload of the staff, but also makes the installation efficiency relatively low. On the other hand, the traditional screw with a gasket only has the function of fixing, Without the function of sealing, it cannot be applied to special equipment such as oil tanks and airtight cabins. Therefore, it is necessary to design a screw that can reduce the workload and have its own sealing structure.

In the fastening connection parts and parts assembly of various equipment and tooling, if the screw and nut anti-loosening treatment is required, there is a contradiction between anti-loosening and tightening or tightening and loosening. For example, the resistance is large when tightening. , or the resistance is large when loosening, or the anti-loosening effect is not good, or the service life is short, and it will be scrapped after 2 to 3 times of use. In a word, all kinds of anti-loosening nuts have the above problems at present. Therefore, it is necessary to utilise a new type of anti-loosening nut with low resistance when tightening or loosening, but with better anti-loosening effect and long service life.

Hydraulic wrench or pulling method Use hydraulic torque wrench or puller to fasten large screws, which saves effort and has high precision. However, hydraulic tools are expensive, screws of different sizes need to be equipped with different wrenches, and now the hydraulic pullers in the world are generally only M160×6. If the screws are too large, special specifications or very few in number, it is extremely uneconomical to equip them with hydraulic tightening tools.

We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: full-thread hexagon socket head bolts, U-bolts with nuts, anti-thread bolts, 4.8 grade hexagonal galvanized nuts and other products, we can provide you with suitable products Your fastener solution.
