Abstract
Description
Technical Field
[0001] This invention relates to the field of PS profile processing, and more particularly to a finishing device for PS profile production. Background Technology
[0002] The purpose of straightening and trimming PS profiles is to eliminate residual internal stress and shape defects after rolling or extrusion, so that the straightness, dimensional accuracy, and surface quality of the profiles meet the technical requirements of subsequent processing (such as cutting, welding, and painting) and assembly. In the actual straightening process, when straightening and trimming PS profiles one by one, the tension is not completely uniformly distributed along the entire PS profile, especially in the central area. If the tension is not properly adjusted, local excessive plasticity or stress concentration can easily occur in the central area, leading to abnormal deformation such as lateral bending or even side bending. This will result in a high scrap rate for straightening and trimming PS profiles, affecting the overall production cost of PS profiles. Furthermore, straightening and trimming PS profiles one by one requires a lot of time for the individual transfer and positioning of PS profiles, affecting the overall production efficiency of PS profiles. Summary of the Invention

The location descriptions selected in the specification, such as upper, lower, lateral, etc., also refer to the directly described and illustrated figures and are semantically applied to the new location when the location changes.
[0026] Example 1: A finishing device for PS profile production, such as... Figures 1-8As shown, the assembly includes a mounting frame 11, a support frame 12, an electric conveyor 2, an electrically controlled stretching machine 3, a lower limiting pressure plate 41, a lower hydraulic press 42, an upper limiting pressure plate 51, an upper hydraulic press 52, a side limiting pressure plate 53, and a side hydraulic press 54. The support frame 12 is fixedly connected to the mounting frame 11. An electric conveyor 2 is installed on both the left and right sides of the support frame 12. An electrically controlled stretching machine 3 is installed on both the left and right sides of the mounting frame 11. The clamping components of the electrically controlled stretching machine 3 have four clamping ports, capable of simultaneously clamping four PS profiles. The electrically controlled stretching machine 3 is aligned with the middle of the support frame 12 and the electric conveyor 2. A lower limiting pressure plate 41 is slidably connected to the support frame 12. The upper surface of the lower limiting pressure plate 41 is initially at the same height as the support frame 12. The support frame 12 is relatively aligned; a lower hydraulic press 42 is installed on the support frame 12; the telescopic end of the lower hydraulic press 42 is fixedly connected to the lower limiting pressure plate 41; an upper limiting pressure plate 51 is slidably connected to the mounting frame 11, and the upper limiting pressure plate 51 is aligned with the upper side of the lower limiting pressure plate 41; an upper hydraulic press 52 is installed on the mounting frame 11; the telescopic end of the upper hydraulic press 52 is fixedly connected to the upper limiting pressure plate 51; a side limiting pressure plate 53 is slidably connected to the lower front and lower rear parts of the upper limiting pressure plate 51; two side hydraulic presses 54 are installed on the upper limiting pressure plate 51; the telescopic ends of the two side hydraulic presses 54 are respectively fixedly connected to the corresponding side limiting pressure plates 53; two groove structures 4101 are opened on the lower limiting pressure plate 41, which are respectively corresponding to the corresponding side limiting pressure plates 53.
[0027] like Figures 4-7 As shown, an electric heating plate 6 is installed in the middle of the lower limiting pressure plate 41; an electric heating plate 6 is also installed in the middle of the upper limiting pressure plate 51; each electric heating plate 6 has several heat dissipation holes 601; each electric heating plate 6 is equipped with two heat dissipation fans 7, and all heat dissipation holes 601 on the same electric heating plate 6 are connected to the corresponding heat dissipation fans 7.
[0028] The working steps of the trimming equipment for PS profile production according to the present invention are as follows.
[0029] First, the external feeding equipment places four PS profiles on the electric conveyor 2. The electric conveyor 2 drives the four PS profiles backward along the support frame 12 between the lower limiting plate 41 and the upper limiting plate 51. Then, the upper hydraulic press 52 drives the upper limiting plate 51 and its connected side limiting plates 53 and side hydraulic press 54 downward until the four PS profiles are aligned between the front and rear side limiting plates 53. The side limiting plates 53 enter the groove 4101 of the lower limiting plate 41, preventing the lower limiting plate from being in the groove. The pressure plate 41 blocks the downward movement of the side limiting pressure plate 53. Then, the two side hydraulic presses 54 push the two side limiting pressure plates 53 toward the four PS profiles. The two side hydraulic presses 54 push the four PS profiles to stick together tightly, so that the ends of the four PS profiles are aligned with the four clamping port structures on the clamping parts of the electric tensioning machine 3 on the same side. Then, the electric tensioning machine 3 controls the clamping parts to clamp the ends of the four PS profiles through the four clamping port structures, thus completing the automatic feeding of the four PS profiles.
[0030] Next, the lower hydraulic press 42 pushes the lower limiting plate 41 upward to press the lower surfaces of the four PS profiles, while the upper hydraulic press 52 pushes the upper limiting plate 51 downward to press the upper surfaces of the four PS profiles. Simultaneously, the two side hydraulic presses 54 push the two side limiting plates 53 to continue moving closer together, so that the front side limiting plate 53 presses the front surface of the first PS profile, and the rear side limiting plate 53 presses the rear surface of the first PS profile. Then, two electric heating plates 6 simultaneously heat the four PS profiles, and the left and right electrically controlled stretching machines 3... Do not pull the two ends of the four PS profiles to the left and right to straighten and trim them. This operation can simultaneously straighten and trim multiple PS profiles, unify the stretching ratio of the four PS profiles, and avoid uneven stress on individual PS profiles. The lower limiting pressure plate 41, together with the upper limiting pressure plate 51 and the two side limiting pressure plates 53, constrains the lateral deformation of the PS profile, prevents the PS profile from twisting or bending in the middle during the stretching process, and allows the PS profile to be heated evenly under pressure, effectively reducing the yield strength of the material and improving the straightening efficiency of the PS profile.
[0031] Then, the two side hydraulic presses 54 drive the two side limiting pressure plates 53 to move in opposite directions to loosen the PS profile. The lower hydraulic press 42 and the side hydraulic press 54 drive the lower limiting pressure plate 41 and the side limiting pressure plate 53 to move in opposite directions to loosen the PS profile. At the same time, the cooling fan 7 uses the heat dissipation holes 601 on the electric heating plate 6 to perform air cooling treatment on the PS profile, so that the temperature of the PS profile is reduced. After the PS profile is gradually cooled, its straightened shape is fixed to prevent springback, thus completing the straightening and trimming work of the four PS profiles.
[0032] Example 2, based on Example 1 above, as follows: Figures 1-7 As shown, in this embodiment, a plurality of support rollers 13 are rotatably connected to the support frame 12; a plurality of U-shaped stacking frames 14 are fixedly connected to the rear side of the support frame 12; during the process of conveying the left and right ends of the PS profile by the electric conveyor 2, the middle part of the PS profile moves backward along the support rollers 13 on the support frame 12, so as to avoid the middle part of the PS profile being subjected to large frictional force due to direct movement along the surface of the support frame 12, which would cause the middle part of the PS profile to be dragged by the frictional force of the surface of the support frame 12, so that the PS profile forms a C-shaped bending structure. The movement allows the PS profiles to be conveyed backward while remaining straight. After the straightening and trimming process is completed, the electric conveyor 2 drives the four PS profiles to fall backward along the support rollers 13 into the U-shaped stacking frame 14. The four PS profiles are vertically stacked on the U-shaped stacking frame 14 while remaining straight, which makes it convenient for workers to manually or by controlling an external packing machine to pack the four PS profiles, eliminating the need for subsequent counting, alignment and stacking of the four PS profiles.
[0033] Example 3, based on Example 1 above, as follows: Figures 1-7 As shown, in this embodiment, each electric heating plate 6 is slidably connected to a lifting plate 81; each lifting plate 81 is fixedly connected to three pressure plates 82, and the pressure plates 82 are slidably connected to the electric heating plate 6, with the pressure plates 82 in the upper and lower electric heating plates 6 aligned with each other; each electric heating plate 6 is equipped with an electric push rod 83; the telescopic end of each electric push rod 83 is fixedly connected to the corresponding lifting plate 81; each pressure plate 82 has a central heat-spreading plate 84 fixedly connected to its front and rear sides; each of the two side limiting pressure plates 53 has a side heat-spreading plate 55 fixedly connected to its opposing sides; all side heat-spreading plates 55 and all central heat-spreading plates 84 are made of silicon carbide heat-spreading material with high compressive strength and excellent heat-spreading effect; during the straightening and trimming process of the PS profile, both ends of the PS profile are stretched. The width of PS profiles will narrow due to material deformation, and gaps will appear between adjacent PS profiles. Therefore, when straightening and trimming the ends of PS profiles, the electric push rod 83 pulls the lifting plate 81, which causes the pressure plate 82 to extend outward from the electric heating plate 6. The pressure plates 82 on the upper and lower sides are inserted into the gaps between the corresponding two PS profiles. The pressure plates 82 inserted between the two PS profiles, together with the side limiting pressure plate 53, clamp all the front and rear sides of the PS profiles, keeping the front and rear surfaces of the PS profiles pressed and limited. At the same time, the silicon carbide heat dissipation material used in the side heat dissipation plate 55 and the middle heat dissipation plate 84 can enhance the uniform diffusion of heat in all areas of the PS profiles, ensuring that the straightening and trimming of the PS profiles is carried out efficiently.
