Technical Field

Background
The material of the hot end heat shield product of the automobile exhaust system is usually stainless steel. Along with the development of technology and the improvement of the requirements on heat insulation performance, when the heat shield steel plate is manufactured, spherical concave-convex arc surfaces which are uniformly pressed and distributed in an array are generally pressed on the steel plate, firstly, the product strength of the heat shield steel plate is enhanced, the weight of the steel plate is reduced to the maximum extent, and the light-weight requirement of an automobile is met; secondly, a cavity matrix is formed between the heat shield and the heat insulation surface of the workpiece by utilizing the concave-convex arc surface, so that heat convection is effectively inhibited, heat conduction is blocked, and the heat insulation effect is further improved; thirdly, the cavity matrix is utilized to avoid the problems of cracking or necking of the steel plate in the stamping or extending process, so that the reject ratio is high.
At present, the spherical concave-convex arc surface is uniformly pressed in an array manner aiming at the steel plate, and the uniform array pressing can be realized by adopting two processes: the technology firstly can not effectively adjust the spacing between the spherical concave-convex arc surfaces according to the requirements (the technology can be realized by replacing the pressing plate, but the required pressing plate mould is more, the replacement technology is complex and time and labor are wasted), and secondly, the steel plate needs to be manually placed and removed (namely, the technology automation can not be realized), so that the labor productivity is greatly wasted; the other is through setting up two compression rollers that are parallel to each other, set up spherical concave convex arc surface simultaneously on the compression roller surface correspondence, utilize the rotation of compression roller for place the steel sheet between them by compression molding and remove, however, this technology firstly can't carry out the effective regulation of interval between two compression rollers (adjust need carry out the demolish of compression roller), and then can't adapt to the steel sheet of different thickness, secondly, its regulation to interval between the spherical concave convex arc surface is produced through compression roller rotational speed and the cooperation of steel sheet feed speed, and is loaded down with trivial details and the complex operation of calculation, reduction pressing efficiency.
In summary, when the existing process equipment is used for profiling the heat shield steel plates with the surfaces being provided with the spherical concave-convex arc array surfaces, the problems that the effective adjustment of the distance between the adjacent concave-convex arc surfaces cannot be carried out according to different heat shield requirements, the adjustment cannot be carried out according to different steel plate thicknesses, the process automation cannot be realized, time and labor are wasted, the pressing efficiency is low and the like exist.

when the heat insulation cover is used, the screw rod 52 is started to rotate firstly, so that the lifting slide block 51 moves up and down in the sliding cavity 112, and then the lifting slide block 51 drives the rotary shaft 21 of the driven roll shaft assembly 30 to move up and down, so that the adjustment of the gap between the driving roll shaft assembly 20 and the driven roll shaft assembly 30 is realized, and the heat insulation cover is suitable for heat insulation cover steel plates with different thicknesses; in the adjusting process, the positioning block 44 moves up and down along with the rotating shaft 21 due to the driving of the rotating shaft 21 of the driven roll shaft assembly 30, so that the adjusting block 45 is pulled by the two connecting rods 47 to move in the direction of approaching or separating from each other on the slide rod 46, and the two auxiliary gears 43 are driven to move in the direction of approaching or separating from each other, so that the meshing state of the transmission chain 48 with the auxiliary gears 43, the gear ring 413 and the driven gears 42 is ensured in the up and down moving process of the driven roll shaft assembly 30, the problems of tooth disengagement, clamping stagnation and the like are avoided when the gap between the driving roll shaft assembly 20 and the driven roll shaft assembly 30 is adjusted according to the heat shield steel plates with different thicknesses, the follow-up adjustment and calibration of the transmission assembly are avoided, and the labor force is saved; then, the heat shield steel plate to be pressed is placed in the gap between the driving roll shaft assembly 20 and the driven roll shaft assembly 30, the driving motor is started to drive the rotating shaft 21 of the driving roll shaft assembly 20 to rotate anticlockwise as shown in fig. 3, the driving gear 411 rotates anticlockwise, the planetary gear 412 rotates clockwise, the gear ring 413 rotates clockwise, the driven gear 42 is driven to rotate clockwise through the transmission chain 48 and the auxiliary gear 43, the pressing of the heat shield steel plate positioned in the gap between the driving roll shaft assembly 20 and the driven roll shaft assembly 30 is achieved, and in the pressing process, the heat shield steel plate is fed at the same time, so that continuous and uninterrupted pressing treatment is achieved.
When the profiling device is required to be adjusted according to the requirements of the shapes (namely the intervals among the cavity matrixes) of the surfaces of different heat shields, firstly, the driven roll shaft assembly 30 is adjusted to the top of the supporting block 11 through the lifting assembly, so that interference generated in the unfolding process of the driving roll shaft assembly 20 and the driven roll shaft assembly 30 is avoided; then, the connecting screw between the slider 22 and the rotating shaft 21 is removed (in this embodiment, the slider 22 is fixedly connected with the rotating shaft 21 through the connecting screw, the connecting screw is uniformly distributed around the central axis of the rotating shaft 21, that is, the outer wall of the rotating shaft 21 and the horizontal chute are in an ectopic manner, and a plurality of rows of positioning screw holes, specifically, 4 rows of positioning screw holes are uniformly formed around the axis of the rotating shaft, each row of positioning screw holes are arranged along the central axis direction of the rotating shaft 21, the slider 22 is provided with a through screw hole corresponding to the positioning screw hole, the connecting screw is screwed into the through screw hole and the positioning screw hole to realize the sliding limit of the slider 22), and then, the sliding slider 22 on the rotating shaft 21 is used for realizing the unfolding or folding of the profiling rib 23 (as shown in fig. 7, which is a schematic diagram of the unfolding of the profiling rib 23 relative to fig. 6, that is, the spacing between two adjacent rows of spherical concave-convex arc surfaces of the heat shield steel plate is increased), and then the adjustment between the driving roll shaft assembly 20 and the driven roll shaft assembly 30 is realized; in the adjusting process, the expanded or folded profiled edges 23 are supported through deformation of the supporting members 232, and the uniform stress in the pressing process is ensured (for example, the telescopic rod adopted in the application can be inflated or deflated in the air guide pipe through an externally arranged air pump device, so that the telescopic rod can be matched with the expansion or contraction of the profiled edges 23 to expand or fold, and the effective support is completed, and if a spring is adopted, the telescopic rod or the spring can be used as the supporting members 232 through deformation of the spring and matched with the expansion or contraction of the profiled edges 23. Afterwards, the hard limit of the sliding block 22 is realized again through the connecting screw; the gap between the driven roll shaft assembly 30 and the driving roll shaft assembly 20 is adjusted again to adapt to the thickness of the heat shield steel plate; finally, profiling is performed according to the method described above.
