The application discloses a manufacturing method of a spiral baffle plate, which adopts a casting process to integrally form a spiral baffle plate unit, and then splices the integrally formed spiral baffle plate unit to form a large-diameter thin-wall spiral baffle plate which is radially continuous; and heat exchange pipe holes on a plate body of the spiral baffle plate unit are integrally formed in the casting process, and the plate body of the spiral baffle plate does not need to be further opened to form the heat exchange pipe holes. Compared with the production and processing method of the existing spiral baffle plate, the method simplifies the process steps, greatly improves the production efficiency of the spiral baffle plate, and is particularly suitable for manufacturing a spiral heat exchange plate with a small central hole or even without a central hole, and has small operation difficulty, short time consumption and high qualified rate.

The application discloses a kind of TGV glass substrate processing equipment and processing method, the TGV glass substrate processing method is, preheating is carried out to the point to be punched before punching, so that the temperature of the point to be processed and surrounding area is increased to form preheating zone, preheating can make the local temperature of glass substrate more uniform, so that when punching, the heat applied by laser cutting is not easy to cause sharp temperature difference, thereby effectively reducing the thermal stress generated in the material, and then eliminating or reducing the occurrence of crack or rough surface condition;The TGV glass substrate processing equipment is connected by the light path of cutting head and preheating head, and the laser beam of cutting head is partially reflected into the preheating head by the beam splitter, so that punching of glass substrate and preheating of the next processing point are carried out at the same time, which saves the processing time of glass substrate.

The utility model relates to metal forming processing technical field, and disclose a pressure -maintaining device based on bearing ring liquid state die forging, including box body, still include: fixedly connected in the inside mounting plate of box body, the inside left side mounting of mounting plate has the motor, through motor drive bidirectional screw rod rotation, utilize its screw thread drive characteristic, the accurate clamping of clamping piece's clamping block is connected in the clamping groove of mould outer wall, this structure design has realized the flexible clamping adaptation of different model mould, only need through motor control bidirectional screw rod's rotation angle, can quick adjustment two clamping piece's interval, make it closely matches mould both sides, completes steady clamping, this device has reduced the adjustment time and manpower cost when replacing mould greatly, need not complex reforming process, has improved production efficiency significantly, satisfies the diversification production demand, has strengthened the versatility and production flexibility of equipment.

The invention discloses an industrial design appearance defect intelligent detection system based on computer vision, and relates to the technical field of computer vision and industrial intelligent detection.During operation of the system, multi-angle space information and multispectral imaging data of the surface of a to-be-detected product are obtained through a preset structured light source module and an array type industrial camera cluster; the method comprises the following steps: reconstructing high-dimensional visual feature distribution on the surface of a product, executing noise suppression and fusion, generating an enhanced feature map with a high signal-to-noise ratio, receiving the enhanced feature map, identifying defects by utilizing an attention mechanism, generating defect candidate areas and a preliminary classification probability, reducing the calculated amount through knowledge distillation, and realizing few-sample migration; and deploying the optimized detection model to a high-parallel hardware acceleration platform, resolving a detection result in real time, and sending a sorting instruction, an alarm signal or a process parameter correction instruction to a production execution system according to a preset quality judgment threshold.

The application relates to a full-range and multi-point automatic pipe feeding device for a mist atomizing nozzle rubber pipe, which comprises a sleeve and a pipe feeding power device. The application breaks the traditional pipe feeding mode and selects the cooperation of a radial extrusion shaping channel and a pipe feeding channel, or the cooperation of a pressure feeding channel and the pipe feeding channel, or the cooperation of the extrusion shaping channel, the pressure feeding channel and the pipe feeding channel, so that the same core output of different deformation or non-deformation rubber pipes is achieved. The defects of assembly failure or high assembly failure rate caused by the deformed rubber pipe are eliminated, continuous and efficient and high-quality production is realized, and the intervention frequency of the operator is greatly reduced. Based on the formed synchronous clamping and feeding, the defects of relative pipe feeding movement of the rubber pipe itself are eliminated, so that the pipe feeding length is kept equal, the consistency of the rubber pipe assembly length is improved, and under the limitation of the extrusion amount, the excessive extrusion is avoided.
