Jiangmen cast iron T-shaped groove platformThe manufacturer processes and sells a 2-meter * 4-meter * 5-meter cast iron welding platform in Jiangmen; Load capacity of 10 tons;
Jiangmen cast iron T-shaped groove platformThe installation process of anchor is as follows:
1. * * Determine installation location * *: According toCast iron T-shaped groove platformDetermine the installation position of the anchor on the platform based on the usage requirements and installation dimensions provided by the anchor. Ensure that the position of the anchor does not affect the use or aesthetics of the platform.
2. * * Drilling * *: Use a drill bit that matches the diameter of the anchor expansion bolt to drill installation holes on the cast iron platform. The depth of the hole should be slightly greater than the length of the expansion bolt.
3. * * Cleaning Holes * *: Use a hair dryer or compressed air to remove dust and debris from the holes.
4. * * Install expansion bolt * *: Insert the expansion bolt into the hole, and then use a hammer to strike the bolt head to expand the expansion sleeve, thereby fixing the expansion bolt in the hole.
5. * * Install anchor * *: Align the embedded parts of the anchor with the expansion bolt, and then tighten the nut. When tightening the nut, be careful not to apply too much force to avoid damaging the anchor or nut.
6. * * Adjust Height * *: If the anchor needs to be adjusted in height, shims or washers can be used for adjustment. Place the gasket or washer between the embedded part of the anchor and the platform, and then tighten the nut.
7. * * Fixed Anchor * *: Tighten all nuts to ensure that the anchor is securely fixed to the cast iron platform.
In addition, for the side roof anchor, the installation steps are as follows:
1. * * Preparation * *: First unscrew the small nut of the side roof anchor and take out the upper pad, then loosen the platform support nut until the thread of the bolt is no longer visible.
2. * * Thread the screw * *: Lift the large cast iron platform with a crane, thread the side roof anchor screw into the reserved side roof anchor hole on the cast iron platform, and then tighten the side roof anchor nut.
3. * * Placement in pit * *: Slowly place the cast iron platform and side roof anchor into the reserved pit, with all side roof anchors in the middle of the pit.
4. Grouting: After the cast iron platform is placed at a certain height, grout is poured into the side anchor pit from the position of the anchor hole on the platform. After 48 hours, when the cement reaches a strength of over 90%, the side anchor is fine tuned to achieve the expected accuracy of the cast iron platform.
5. * * Follow up inspection * *: After adjusting the accuracy of the cast iron platform, the accuracy should be checked six months later. If there is any deviation, it should be adjusted again. Check and debug once a year in the future.
When installing the anchor, attention should be paid to using appropriate tools and materials. The length of the expansion bolt should be slightly greater than the depth of the hole to ensure that the expansion sleeve has sufficient expansion space. When tightening the nut, pay attention to applying moderate force to avoid damaging the anchor or nut. After the installation of the anchor, it should be checked in a timely manner to ensure its firmness and reliability, and the anchor should be regularly inspected and maintained to ensure its safety during use.


Guide to Avoiding Pits in Purchasing Cast Iron Platforms: A Comprehensive Analysis of Seven Core Points from Material to After sales
1、 Material selection: Avoid low strength cast iron, prioritize HT200/HT300
Core requirements: The cast iron platform must have high strength, wear resistance, and deformation resistance, and the material is the foundation.
Avoiding pitfalls:
Be cautious of using low-quality cast iron (such as high impurities and insufficient strength) in low-priced products, which can easily cause deformation or cracking of the platform.
Recommended material: HT200 or HT300 gray cast iron, tensile strength ≥ 200MPa, hardness HB170-240, excellent wear resistance and shock absorption.
Verification method: The manufacturer is required to provide a material testing report to verify the chemical composition (such as carbon content of 3.3% -3.6%) and mechanical performance indicators.
2、 Accuracy level: Choose as needed to avoid "high configuration, low usage" or "low configuration overload"
Core requirement: The accuracy level directly affects the effectiveness of use and needs to be matched with actual requirements.
Avoiding pitfalls:
Excessive pursuit of high precision (such as level 00) will increase costs, while low precision (such as level 3) may not meet the requirements of precision measurement.
Accuracy level reference:
Level 00: Flatness error less than or equal to 0.003mm/m, suitable for metrology rooms and research institutions;
Level 0: ≤ 0.006mm/m, suitable for machine tool calibration and precision testing;
Level 1: ≤ 0.012mm/m, suitable for ordinary mechanical processing;
Level 2-3: Suitable for low precision scenarios such as marking and assembly by fitters.
Verification method: Use a laser interferometer or electronic level to check the flatness of the platform and verify if it meets the nominal level.
3、 Carrying capacity: Reserve 20% -30% safety margin
Core requirement: The platform must withstand the total weight of the workpiece, fixture, and equipment, as overloading can cause deformation.
Avoiding pitfalls:
When estimating the carrying capacity, dynamic loads (such as vibration and impact) are ignored, or safety margins are not reserved.
Calculation example: If the actual total weight is 5 tons, it is recommended to choose a platform with a bearing capacity of ≥ 6.5 tons (5 × 1.3).
Verification method: Check the bearing capacity curve provided by the manufacturer, or request a static load test (such as loading to 1.2 times the nominal bearing capacity for 24 hours without deformation).
4、 T-shaped slot design: matching fasteners to avoid "large slot with small parts" or "small slot with large parts"
Core requirement: The T-shaped groove is used to fix the workpiece, and the size and spacing should match the matching bolts and nuts.
Avoiding pitfalls:
The T-shaped groove opening is too large or too small, causing the bolt to be unable to be inserted or fixed unstably;
Unreasonable spacing affects the flexibility of fixture layout.
Design standards:
Opening width: Select according to the bolt diameter (e.g. M16 bolt corresponds to an opening of 22mm);
Spacing: commonly 50mm, 100mm, 150mm, depending on the size of the workpiece and the number of fixtures;
Depth: ≥ 1.5 times the diameter of the bolt (e.g. M16 bolt corresponds to a depth of 24mm).
Verification method: Bring commonly used bolts and nuts to the manufacturer for trial assembly and check if they match.
5、 Casting process: Resin sand molding is superior to cement sand molding
Core requirement: The casting process affects the internal quality and surface accuracy of the platform.
Avoiding pitfalls:
Cement sand molding has low cost, but it is prone to defects such as pores and sand holes, which can reduce the strength of the platform;
Resin sand molding costs 20% -30% more, but has good surface smoothness and high dimensional accuracy (tolerance ± 0.5mm).
Verification method: Observe whether there are uniform scratch marks on the surface of the platform (resin sand molding platform scratch point density ≥ 12 points/cm2), or request the manufacturer to provide casting process instructions.
6、 Heat treatment process: Stress relief annealing is key
Core requirement: Heat treatment can eliminate internal stresses in casting and prevent platform deformation.
Avoiding pitfalls:
Failure to perform heat treatment or insufficient heat treatment temperature and time, resulting in gradual deformation of the platform during use;
Standard process: Stress relief annealing (kept at 550-650 ℃ for 4-8 hours, cooled in the furnace to below 200 ℃ and removed from the furnace).
Verification method: The manufacturer is required to provide heat treatment records or use an X-ray diffractometer to detect residual stress (stress ≤ 50MPa).
7、 After sales service: prioritize "full lifecycle" support
Core requirement: The platform needs to be used for a long time, and after-sales service directly affects the cost of use.
Avoiding pitfalls:
The manufacturer only provides basic installation and does not include debugging, maintenance guidance, or quick response repairs;
High quality service content:
Free installation and debugging (including horizontal calibration and precision re inspection);
Regular maintenance guidance (such as checking flatness every 6 months);
Respond to quality issues within 24 hours and provide backup platforms or on-site repairs.
Verification method: Check the manufacturer's service contract terms or contact old customers to understand the actual service situation.
Summary: Tips for Choosing Cast Iron Platforms
The material selection is HT200/300, with precision as needed and no waste;
Leave 20% -30% of the load capacity, and match the T-shaped groove with the component;
Resin sand heat treatment, no tearing during the entire after-sales cycle. ”
By strictly controlling the seven key points mentioned above, common pitfalls in purchasing cast iron platforms can be effectively avoided, ensuring the selection of high-quality platforms with high cost-effectiveness and long lifespan.
