This utility model provides a device for spot welding a catalyst support and a nut, which can effectively control the inward shrinkage of the catalyst support and avoid deformation of the catalyst support due to uneven temperature. It includes an upper electrode and a lower electrode that cooperate with each other. The lower electrode is provided with a positioning pin, which can position the nut and the support. The upper electrode is characterized by having an inner support fixed on it, and a wear-resistant ring is fixed on the outer side of the inner support. The outer diameter of the wear-resistant ring matches the size of the catalyst support. During welding, the wear-resistant ring can support the support in the catalyst support and limit the legs of the catalyst support to prevent the legs of the catalyst support from shrinking inward.

The invention belongs to the technical field of titanium alloy forming, and relates to a titanium alloy sheet bending forming method which comprises the following steps: (1) spraying: cleaning the surface of a sheet, spraying a protective coating until the film thickness is 0.2-0.3 mm, and drying the film in the shade; (2) annealing is conducted, specifically, the thin plate obtained after spraying in the step (1) is annealed, and the annealing temperature ranges from 700 DEG C to 925 DEG C; (3) bending is conducted, specifically, after annealing and heat preservation are finished, bending is conducted, and after bending forming is conducted, natural cooling is conducted to the room temperature; and (4) the step (2) and the step (3) are repeated, and bending forming of the whole product is completed. By the adoption of the method, bending forming of titanium alloy parts of different thicknesses and different materials can be achieved, the utilization rate of raw materials of products is increased, and the machining cost is reduced.

This utility model relates to the technical field of weighbridges, and more particularly to a visual wheel-by-wheel weighbridge. It comprises two weighbridges, a frame, a device for timed data acquisition, a GPS / BeiDou central control vehicle-mounted instrument, a data platform, a weighing image display screen, and a camera. The timed data acquisition device collects the output signals of the two weighbridges sequentially and at different times. The output signals are transmitted via the GPS / BeiDou central control vehicle-mounted instrument to the data platform for processing, and the time-wheel pressure signal curve structure of each wheel is recorded. This significantly reduces the size of the weighbridge equipment, reduces the installation, calibration, and maintenance costs of the weighbridge, dynamically calculates the weighing time using the wheel pressure signal curve to balance detection efficiency and accuracy requirements, further saves weighing time, improves weighing efficiency, and simultaneously achieves wheel-by-wheel weight statistics and axle off-center load rate calculation.
