[0028] The limiting plate 41 is welded to the back of the pressing plate, and the side thereof is fitted with the fixing block 43 , and a liner 42 is provided at the connection between the fixing block and the side of the pressing plate to reduce friction and wear.

[0029] The fixing block 43 is fixed to the slide block 2 by bolts to fix the pressure plate assembly.

[0030] The fixing member 7 includes a support plate 71 and a fixing clamp 72 arranged below the middle of the support plate. After the fixing clamp is inserted into the fixing slot 23 of the slider, it is fixed by screws 3 to achieve the connection between the water tank assembly and the slider.

[0043] This embodiment provides another implementation method of the tension beam structure of a novel belt tensioner, focusing on further optimization of the water tank assembly and enhanced design of the slider and pressure plate assembly to meet higher requirements for strip processing.

[0044] A novel tension beam structure of a belt tension machine mainly comprises a water tank assembly 1, a slider 2 and a pressure plate assembly 4.

[0045] Sink component 1: The water tank assembly continues to use 45# forged steel as raw material, and is hollowed out to form a basic shape. In order to further improve its strength and wear resistance, this embodiment adds an additional heat treatment step in the manufacturing process of the water tank assembly, that is, secondary tempering is performed after quenching to eliminate internal stress and improve the comprehensive mechanical properties of the material.

[0046] Before the ceramic coating, the friction surface of the water tank assembly in contact with the belt is sandblasted to remove the surface oxide layer and tiny defects to ensure the close bonding between the coating and the substrate. The ceramic coating layer uses highly wear-resistant and highly corrosion-resistant ceramic materials, which are evenly covered on the friction surface of the water tank assembly through plasma spraying technology to further improve its wear resistance and corrosion resistance.

[0047] The interior of the water tank assembly is divided more finely by a group of horizontal partitions and nine groups of longitudinal partitions to form more independent water storage tanks to optimize the flow path of cooling water and improve cooling efficiency; at the same time, argon arc welding is used for welding at the joints between the partitions to ensure sealing and structural strength.

[0048] The water injection pipe 6 is equipped with a flow regulating valve and a filter as standard, so that the user can accurately control the injection amount of cooling water and filter impurities according to actual needs. In addition, a water level monitoring device is added to monitor the water level in the water tank in real time through a sensor, and issue an alarm when the water level is too low, reminding the operator to replenish water in time.

[0049] Enhanced Slider 2: Made of high-strength alloy steel, the thickness of the two side vertical plates 22 and the middle cross frame 21 are increased to improve their bearing capacity and anti-deformation ability. The fixing slot 23 opened on the cross frame is precisely processed to ensure a close fit with the fixing head 72 of the fixing member 7 to reduce the possibility of loosening and displacement.

[0050] On the reinforcing base plate 5 welded at the bottom of the slider, multiple reinforcing ribs are added to enhance the rigidity and overall stability of the slider. At the same time, the reinforcing base plate is connected to the slider body with high-strength bolts, and a sealant is applied for sealing to prevent cooling water leakage.

[0051] The pressing plate 44 is made of wear-resistant alloy steel, and the surface is shot-peened to improve its surface hardness and fatigue resistance. The fixing block 43 is made of stainless steel to prevent rust and corrosion.

[0052] The groove in the middle of the pressure plate is optimized to better adapt to the shape and tension changes of the belt. The two ends of the pressure plate are connected to the vertical plate 22 on the side of the slider by interference fit and fastened by high-strength bolts and locking washers. The fitting surface between the limit plate 41 and the fixed block 43 is precisely processed and polished to reduce friction and wear.

[0053] The liner 42 provided at the side connection between the fixing block 43 and the pressing plate 44 is made of a highly elastic and wear-resistant polyurethane material to absorb vibration and impact and protect the pressing plate and the slider from damage.

[0054] Assembly and debugging: Assemble the processed water tank assembly 1, slider 2 and pressure plate assembly 4 according to the design requirements. During the assembly process, pay attention to the matching accuracy between the components and the control of the tightening torque. After the assembly is completed, carry out overall debugging and trial operation to check the operation of the cooling water circulation system, the stability and accuracy of the tension beam structure, and the operation status of the belt under tension. Make corresponding adjustments and optimizations based on the debugging results to ensure that the tension beam structure meets the design requirements and reaches the best working state.
