Through setting up the pressure assembly, make staff only need to go up and down straight line movement quick drive mechanism can cooperate transmission mechanism drive clamping plate to rise and release elasticated band or drop and press the elasticated band, thereby conveniently and quickly complete the clamping operation to the elasticated band end, effectively improved the convenience and practicality of the device.

The utility model provides a kind of substrate rack, including support frame and protection component, support frame has opposite front and back, and at least one substrate placement area through front and back, wherein the front of support frame and the plating film surface of substrate are oriented same;Protection component is at least set on the front of support frame, for preventing heat directly radiates to support frame during plating film process, and preventing film layer directly covers on support frame;The utility model adds protection component on support frame, the protection component can effectively block radiation heat, prevent support frame from serious deformation due to temperature is too high, to avoid affecting normal use of substrate rack or leading to its damage.In addition, the protection component can also prevent film layer from covering support frame in large quantities, to extend the cleaning maintenance cycle and service life of substrate rack.

The invention relates to the technical field of aluminum alloy machining, in particular to high-corrosion-resistance colorful aluminum alloy decorating part forming machining equipment which comprises a conveying system, an aluminum alloy plate and a mold used in cooperation with the aluminum alloy plate, and further comprises four clamping plates, a first clamping plate, a second clamping plate, a third clamping plate and a fourth clamping plate, according to the high-corrosion-resistance colorful aluminum alloy decorating part forming machining equipment, the two sets of clamping plates are matched with the four centering plates, the centering plates are driven by the correcting part to conduct synchronous extrusion and correction, it is ensured that the aluminum alloy plate is accurately aligned with the mold, and the machining efficiency is improved. Therefore, when the end of the aluminum alloy plate is clamped subsequently, the end of the aluminum alloy plate is filled through the mold, the situation that the plate is seriously deformed or damaged due to the fact that the clamping force of the clamping plate is too large is avoided, meanwhile, rapid mold replacement is achieved through an inserting rod and inserting groove matching structure of the assembling and disassembling piece, and the equipment maintenance and production switching efficiency is remarkably improved; and the downtime is reduced.
