Cast iron workbench with splicing

Hebei Beizhong manufacturer produces splicing plates based on the designed splicing plate blueprint. First, individual cast iron plates are cast, and then multiple cast iron plates are combined to form the splicing plate, ensuring that the grooves and holes align neatly on the surface. Splicing plates are mostly used for larger workbenches where a single cast iron plate cannot meet user requirements. This splicing method compensates for the limitations of single cast iron plates. Most work surfaces have T-slots, primarily used for securing workpieces.
Types of splicing plates: Flat splicing plates, T-slot splicing plates, etc.
Applications of splicing plates: They serve as foundational work surfaces for fitters to debug equipment, assemble devices, and perform maintenance. Widely used in machining, tool workshops, machine (inspection) repair shops, large equipment bases, metrology rooms, and for inspection, measurement, and grinding in precision machining. They enable accurate measurement and inspection of workpiece flatness and straightness.
Technical requirements for splicing plates: Straight-line connections are used during splicing, so the four corners of the splicing plate must be 90° right angles during processing. In large plate splicing processes, a collimator should be used for inspection, offering better precision and efficiency compared to traditional plate splicing methods.
Advantages of splicing plates: Since the precision of large cast iron plates (4000*6000--3000*8000mm) cannot meet the demands of actual production, smaller规格 cast iron plates are spliced to achieve the required size. This splicing method has no impact on usage. It addresses issues such as production and transportation of large cast iron plates, especially in applications like power tests, where it helps distribute the longitudinal and lateral torque承受 by the plates.
Surface precision of splicing plates: Manufactured according to the latest national standard GB/T22095-2008, achieved through scraping or grinding, and classified into grades 0, 1, 2, and 3.
Material of splicing plates: The working surface hardness is HB170-240. After two artificial treatments (artificial annealing at 600°C-700°C and natural aging for 2-3 years), the product exhibits stable precision and good wear resistance.
Installation method of splicing plates: The installation steps mainly include: measuring and inspecting the splicing plate foundation---installing ground anchors or anchor bolts at the bottom of the plate---positioning the plate foundation---initial adjustment of the plate---grouting the plate---curing of the grout---fine adjustment of the plate---precision acceptance of the plate---appearance acceptance of the plate. Splicing plates are adjusted primarily using ground anchors or anchor bolts. Other adjustment methods include adjustment via shims, jacking screws, etc. The surface precision after adjustment depends on the adjustment area and the customer's intended use.
