The matching is convenient, the contact area of the rolling wheels and the guide rail is small, the friction force is small, and the operation and the control are free.

The invention relates to a small narrow band bending straightener and belongs to the technical field of metal bar straightening equipment. The straightener consists of straightening roll group mechanism positioned on an upper part, a bending roll group in the middle, a machine seat and a power mechanism at bottom and a control device, wherein the straightening roll group mechanism comprises a straightening roll group and a supporting and regulating device, and the straightening roll group consists of a straightening roll and a pair of pressing rolls; the bending roll group consists of two pairs of driving and driven bending rolls and a pressing roll; the power mechanism comprises a main driving motor and a transmission mechanism; the driving and driven bending rolls and the pressing roll are arranged on the back plate of the machine base through a rotating shaft cantilever, and the straightening roll and the pressing rolls are arranged on the supporting and regulating device by rotating shaft cantilevers; the main driving motor is connected with the rotating shaft of the driving bending roll through the transmission mechanism, the main driving motor is below a working platform panel, and the transmission mechanism is arranged behind the back plate of the machine frame; and the two motors are controlled by the control device. The straightener has the advantages that: band straightening speed and the relative positions of the straightening rolls can be regulated; the structure is simple and compact; the band insertion and operation are convenient; the straightening effect is good; and the like.

The invention belongs to the technical field of auxiliary mounting, and particularly relates to a flange alignment tool and an operation method. The flange alignment tool comprises a base, positioning mechanisms, a connecting rod and an alignment mechanism, wherein one end of each positioning mechanism is connected with the base, and the other end of the corresponding positioning mechanism is suitable for being connected with a bolt hole of a first flange; the connecting rod is vertically connected with the base, and can be longitudinally adjusted relative to the base; one end of the alignment mechanism is arranged on the connecting rod, and the other end of the alignment mechanism can be abutted against a second flange; the alignment mechanism can be adjusted along the axial direction perpendicular to the second flange, relative to the connecting rod; and the alignment mechanism and the positioning mechanisms are in parallel arrangement. Through the adoption of the flange alignment tool, flanges can be rapidly aligned. The flange alignment tool has the advantages of being flexible in adjustment, and small in space of occupation.

The invention relates to a clamping structure for machining plunger inclined grooves. The clamping structure comprises base disc which in location connection with a location round pin of a bottom plate. A first center mechanism and a clamp mechanism are fixedly connected onto the bottom plate respectively. A second center mechanism is arranged in the clamp mechanism, and a location mechanism is arranged on the clamp mechanism. According to the clamping structure, a center hole of one end and a cap of the other end of the plunger are clamped through a yin center and a yang center respectively, so that the circle center location of the two ends of the plunger is achieved, and the location reference is consistent with the design reference; the location mechanism is use, a location block of the location mechanism used for being attached to the plunger flat surface, the relative position of the plunger axis direction is adjustable through the yin center and the yang center, and the adjustability of the rotation direction and the machining angle is achieved through a dial.

Provided is a resonant cavity, including a cavity body, at least two metamaterial plates located inside the cavity body, each metamaterial plate including at least one metamaterial sheet, the cavity body being further installed thereon with an adjustment device for adjusting the relative position between the at least two metamaterial plates. The present invention realizes the purpose of frequency reduction by way of placing a metamaterial plate in a resonant cavity and using the high refractive index property of metamaterial, and further realizes trimming of the resonant frequency under the condition of reduced frequency by providing an adjustment device for the metamaterial plate to make the relative position between each metamaterial plate adjustable, which can meet more accurate filtering demands. In addition, also provided is a filter having said resonant cavity.
