The utility model discloses an auxiliary structure of feeding of electrohydraulic bending machine belongs to electrohydraulic bending machine technical field. An auxiliary structure of feeding of electrohydraulic bending machine, including electrohydraulic bending machine main part and two support frames, the both sides below support frame all are provided with guide frame, and the outside sliding connection of guide frame has moving block, and the installation of two moving blocks has the moving branch board, and the outside sliding connection of moving branch board has two auxiliary positioning frame. The utility model solves the problem that the existing bending machine feeding auxiliary device is limited by product specification, leads to the use effect of auxiliary structure to be not good, influences the processing effect, and the utility model adjusts the position of moving block in guide frame and the position of auxiliary positioning frame according to product specification, and after moving to the both ends of product, through the elongation second electric cylinder, the clamping plate presses down the product to the upper end of push -on frame, clamps the both ends of product, and can satisfy the asymmetric product type according to product type, and the adaptability is good, and it is convenient for long -term work.

The utility model discloses a high-strength light-weight front wheel cover reinforcing plate for an automobile, and belongs to the technical field of automobile accessories. The high-strength light-weight front wheel cover reinforcing plate for the automobile comprises a reinforcing plate body, the reinforcing plate body comprises a protruding part, two outer reinforcing plates and buffering protruding strips, a plurality of outer supporting parts are arranged on the outer portions of the two outer reinforcing plates, and a plurality of inner buffering grooves are formed in the inner portions of the two outer reinforcing plates. According to the front wheel cover reinforcing plate, the problems that the structural strength of an existing front wheel cover reinforcing plate cannot be kept stable, the weight of the reinforcing plate is too large, stability on a vehicle is affected, and long-term use is not facilitated are solved, protection is achieved through the outer supporting part on the surface of the outer reinforcing plate, and meanwhile the overall weight of the outer reinforcing plate can be reduced through the inner buffering groove; and when the reinforcing plate main body is extruded and impacted, the pressure of the front wheel cover is reduced, so that the pressure resistance of the front wheel cover is improved, and long-term work is facilitated.

The utility model discloses a mobile filter device for waterborne epoxy resin belongs to waterborne epoxy resin production technical field. A mobile filter device for waterborne epoxy resin, including filter main part and mobile seat, the inside installation of filter main part has filter drum, and the one side of filter main part is provided with diaphragm pump, and the both sides of mobile seat are hinged and are connected with photovoltaic board, and the inside of mobile seat is provided with battery. The utility model solves the problem that the existing filter device is limited by environment, is not favorable to moving, and the adaptability is not good, the utility model moves through universal wheel drive filter main part and diaphragm pump, and the power supply of servo motor and diaphragm pump is given through battery, provides power supply and carries out filtering work, adapts to temporary outdoor work, installs timer and adjusts stepping motor, adapts to sunshine position, improves the receiving effect of photovoltaic board, and photovoltaic board stores into battery through converter with the converted electric energy, to improve the use effect.

This utility model relates to the field of router board technology, and discloses a router board component that supports modular expansion. In modern network communication, existing router board expansion suffers from problems such as cumbersome operation, unstable connection, difficult disassembly and assembly, and poor heat dissipation. This component consists of multiple router board units that can be stacked vertically. Each board unit includes an expansion box and a board body, which are connected by a snap-fit ​​component. The L-shaped latch of the lower unit is pushed by the abutment protrusion on the support block of the upper unit, automatically rotates and retracts, and snaps into the limiting groove of the upper unit, completing the connection and locking. To disassemble, the latch can be unlocked by moving the sliding base. At the same time, the board body is easy to install, and the stacked components form a heat dissipation channel. This component improves assembly efficiency and structural stability, enhances heat dissipation, and is suitable for router board expansion scenarios.
