According to the riveting punch, the positioning pin is matched with the center hole for positioning, the punching pin punches the edge of the riveting groove, the thrust mechanism pushes the wafer, and therefore one-time riveting forming is achieved, and the production efficiency and the product yield are improved.

This utility model discloses a grinding wheel groove structure, a grinding wheel, and a grinding auxiliary device, including a contoured groove for adapting to the edge of the glass and symmetrical first and second inclined surfaces. The bottom edges of the first and second inclined surfaces are respectively connected to the two opposite sides of the contoured groove. The included angle formed by the intersection of the extended lines of the first and second inclined surfaces ranges from 45° to 55°. This utility model adds a first and second inclined surface, thus forming a larger groove. This allows for a smoother transition of the edge arch height between the contoured groove and the glass during the grinding process. Furthermore, due to the enlarged groove, the cooling effect of the cooling water during the grinding process is better, and the ground glass powder is carried away by the cooling water more promptly. This reduces the probability of defects such as scorching and edge breakage during the grinding process, resulting in a smoother edge and improved grinding effect.

The application discloses a racing road bicycle tire, which comprises a tire, the tire comprises a tread and a carcass, a center area is arranged at the center of the tread, and side edge areas are arranged at both sides of the tread. The unfolding width of the center area of the tread of the tire is 15%-35% of the total unfolding width of the tread, the center area is a smooth surface, a plurality of inverted Z-shaped pattern groups are arranged in the side edge areas, the pattern group is cut into a plurality of diamond blocks by a plurality of inclined long grooves and high transverse inclined short grooves, the included angles of the inner and outer sidewalls of the inclined long grooves with the radial normal are different, the included angle β of the outer sidewall with the radial normal is greater than the included angle α of the inner sidewall with the radial normal, and the drainage and low rolling resistance performance are considered.

This invention discloses a spectral reconstruction method for a channel-type polarization spectrometer based on adaptive sparse bases, comprising the following steps: 1. Input data: Obtain the measured spectrum through a CSP modulation system; 2. Obtain the preliminary reconstructed spectrum: Input a sparse basis matrix composed of a traditional Legendre polynomial and a DCT basis, and obtain an approximate spectral solution using compressed channel polarization technology; 3. Form an adaptive sparse basis matrix and iteratively solve for the reconstructed spectrum: By removing "useless atoms" from the original sparse basis and adding "sub-subdivision atoms" to the remaining effective atomic functions, an adaptive sparse basis matrix is ​​formed. The adaptive sparse basis matrix is ​​then iteratively solved to obtain a better reconstructed spectrum. This invention improves the reconstruction effect of traditional compressed channel polarization methods for high-frequency spectral signals and those with multiple absorption peaks, further enhancing the reconstruction accuracy of high-frequency complex spectra.

This utility model belongs to the technical field of fabric spreading machine accessories, and relates to an edge-trimming structure for a fabric spreading machine. It includes an edge-trimming flat tube, with a fabric guide plate horizontally arranged above the tube. Edge-trimming mechanisms driven by an edge-trimming motor are symmetrically arranged on both sides of the fabric guide plate. Each edge-trimming mechanism includes a first pulley, a second pulley, and a synchronous belt. The upper surface of the synchronous belt forms an edge-trimming surface that connects with the fabric guide plate. The edge-trimming surface is conveyed outwards and inclined upwards along the conveying direction. The first pulley is mounted on an inner fixed seat, and the second pulley is mounted on an outer movable seat. A connecting pipe is provided between the fixed seat and the movable seat. One end of the connecting pipe is hinged to the fixed seat, and the other end is hinged to the movable seat. The movable seat is connected to a height adjustment mechanism. The edge-trimming structure for the fabric spreading machine provided by this utility model has better edge-trimming effect and better adaptability.
