Today, zhejiang weigao Industrial Bolt Factory will give you a detailed introduction to the four methods of Industrial Bolt device
For industrial bolts that have no strict requirements for tightening force, general wrenches are generally used for tightening, pneumatic or electric wrenches are used for tightening, and sledgehammers or loose hammers are impacted by single-end wrenches. Torque method or hydraulic tension tightening method.
In the fixation method of the equipment and the foundation, the Industrial Bolt is the first choice to connect, adjust the horn to level the equipment, and then grouting to fix the equipment on the foundation of the equipment. 1. Fix Industrial Bolt Used to fix equipment without intense oscillation and impact. Such as straight hook bolt, hook bolt, bending bolt, U-shaped bolt, claw bolt, anchor plate bolt, etc.
2. Activity Industrial Bolt is used to fix heavy mechanical equipment with intense vibration and impact during fixed work. Such as T-head bolts, screw-in bolts, counter-twist bolts, etc.
3. Some of the simple equipment or auxiliary equipment that is still standing sometimes use the expansion bolt Industrial Bolt connection method. The Industrial Bolt device shall meet the following requirements:
(1) The distance from the center of the expansion anchor Industrial Bolt to the margin of the root base is not less than 7 times the diameter of the expansion anchor Industrial Bolt;
(2) The base strength of the Industrial Bolt of the expansion anchor of the device shall not be less than 10MPa;
(3) There should be no cracks in the drilled hole.When drilling, avoid collision between the drill bit and the steel bars and buried pipes in the root;
(4) The diameter and depth of the drill hole should match the Industrial Bolt.
As a professional China Stud Supplier, Zhejiang Weigao Standard Parts Co., Ltd., we look forward to your message and look forward to serving you.

1. Code for Construction and Acceptance of Steel Structure Engineering (GB 50205-2001)

2. Code for Manufacturing Railway Steel Bridges (TB10212-2012)

3. Technical Requirements for High Strength Large Hexagon Head Bolts, Large Hexagon Nuts and Steel Structure Washers (GB/T1231-2006)

(1) The construction sequence and initial and torsional moments of hexagonal flange bolt connection pairs shall conform to the design requirements and regulations of JGJ82, which is the current industry standard for design, construction and acceptance of large hexagonal bolt connections.

(2) After finally tightening a pair of Hexagon Flange Bolt, the bolt threads shall be exposed by 2-3 retaining rings, of which 10% of the bolt threads shall be exposed by 1 retaining ring or 4 retaining rings. Number of inspections: 5% of the number of nodes, not less than 10.

(3) The friction surface of hexagonal flange bolt connection shall be kept dry and clean. There shall be no flash, burr, welding spatter, welding scar, iron oxide scale, dirt, etc. In addition to the design requirements, paint shall not be applied.

(4) Hexagonal flange bolts shall be able to freely penetrate through bolt holes. High strength bolt holes should not be reamed by gas cutting. The number of reaming shall be approved by the design. The hole diameter after reaming shall not exceed 1.2D(d is the bolt diameter).

(5) After the hexagonal flange bolt spherical joint is assembled, the high-strength bolt and the spherical joint shall be closely connected. The thread length of the high-strength bolt screwed into the bolt ball should not be less than 1.0d(d is the diameter of the bolt), and there should be no clearance or looseness at the joint.

The above is about the inspection of hexagonal flange bolts. Our products have been strictly inspected to ensure compliance with relevant national standards. Our products have been updated and improved to achieve better results.

(1) The bolt factory shall assemble the engine oil pan and check the usage of the engine bearing bush when carrying out secondary maintenance for 12000 kilometers each time. If the clearance of individual bearing bushes is found to be too large, the bolt shall be replaced, and the connecting rod bolt shall be replaced at the same time. During normal operation, if the engine is found to have unstable operation and abnormal noise, it should also be stopped and checked in time.
(2) The newly replaced connecting rod bolts shall be checked during each maintenance. Attention should be paid to whether there are cracks or dents in the head, guide part and thread part of the Hexagon Flange Bolt, whether the tooth shape and pitch of the thread are abnormal, and whether there are abnormal situations should be resolutely avoided.
(3) When assembling the connecting rod cap, use a torque wrench to tighten it according to the specified specifications to prevent excessive and small torque.
④ Select the connecting rod hexagon flange bolts produced by the matching factory.
