References to directional terms, such as "inner", "outer", "top", "bottom", etc., in embodiments of the present utility model are merely with reference to the orientation of the drawings. Accordingly, directional terminology is used for better, clearer description and understanding of embodiments of the utility model, and is not intended to indicate or imply that the devices or elements so referred to must be in a particular orientation, be constructed and operate in a particular orientation, and therefore should not be construed as limiting of embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
The utility model provides a device for correcting a copper net for an average hot plate by adopting an upper pressure head and a lower pressure head, which is shown in figure 4. The device comprises: an upper ram 3 and a lower ram 4, in particular:
The upper press head 3 is composed of an upper press head main body 31 with an arc surface at one end surface, the arc surface is an upper press head pressing surface 32 which is contacted with the processed copper net 1, and a connecting rod 33 is arranged at the upper end surface of the upper press head main body 31 and connected with a cylinder for applying downward pressure.
The lower press head 4 is formed by a lower press head main body 41 with a concave structure and is used for bearing the processed copper net 1, and a lower press head bearing surface 42 of the lower press head 4 has a second radian matched with the first radian of the upper press head pressing surface 32.
As shown in fig. 1, the copper net is in a roll shape before being processed, the radius of a roll core is R, and when the copper net is cut and processed into a copper net to be used (as shown in fig. 2), the surface of the copper net still maintains the radian when the copper net is curled. Therefore, the positioning and welding requirements in the vacuum cavity etched by the VC soaking plate can greatly increase the difficulty, the VC soaking plate is usually leveled by adopting a manual leveling mode, a large amount of manpower is consumed, and the effect is not very good.
The structure of the utility model can well solve the problem of manual processing.
When the device is used, the rolled copper net is processed into a required shape and then is conveyed to the appointed parts of the upper pressure head 3 and the lower pressure head 4 through the conveyor belt 2 (shown in figure 3), and the radian of the processed copper net 1 is downward and opposite to the radian direction of the upper pressure head.
In order to achieve a better leveling effect, the arc radius R Upper part of the first radian meets the requirement that R Upper part =r+5-10 mm, wherein R is the core radius of the unprocessed copper mesh, and the arc radius R Upper part of the first radian is 5-10 mm smaller than the arc radius R Lower part(s) of the second radian so as to prevent over-correction.
The hardness of the upper ram 3 is less than the hardness of the lower ram 4. Preferably, the upper pressing head 3 and the lower pressing head 4 are made of polyurethane materials, further, the shore hardness of the upper pressing head 3 is 20+/-3, and the shore hardness of the lower pressing head 4 is 40-50. The hardness of the upper pressure head is slightly microsoft, so that the correction effect is ensured.
When the upper pressure head 3 is driven by the air cylinder to move downwards, the lower pressure head 4 is not moved, the copper net product with warp deformation is pressed in the lower pressure head 4, and the Shore hardness of the upper pressure head 3 is smaller than that of the lower pressure head 4, so that deformation can be generated according to the circular arc of the lower pressure head 4, and the pressure maintaining time after pressing can be controlled by a time relay for better leveling effect.
After the compacting time is reached, the negative pressure suction hole on the upper pressure head 3 generates negative pressure (an electromagnetic valve for controlling the generation of negative pressure can be arranged to start during actual production, and the negative pressure is generated through compressed air), so that the leveled copper mesh is sucked, when the leveling effect requirement is reached, the upper pressure head 3 is driven by the driving cylinder, the processed copper mesh 1 is conveyed to a good product area, and then the negative pressure is closed, so that the processed copper mesh falls at a corresponding position.
As shown in FIG. 5, the utility model also discloses a leveling system for leveling the copper net for the hot plate by adopting the upper and lower pressing heads, which comprises a plurality of groups of devices for leveling the copper net for the hot plate by adopting the upper and lower pressing heads, wherein the devices are arranged at preset intervals in sequence.
The figure shows 3 groups of devices, preferably, the radius R Upper part N of the arc of the first radian of the Nth upper pressure head is 5-10 mm smaller than the radius R Lower part(s) N of the arc of the second radian of the Nth lower pressure head; the arc radius R Upper part N of the first radian of the Nth upper press head is 5-10 mm smaller than the arc radius R Upper part N+1 of the first radian of the (n+1) th upper press head. Namely, the arc radius R Upper part 2 of the first radian of the 2 nd upper pressure head is 5-10 mm smaller than the arc radius R Lower part(s) 2 of the second radian of the 2 nd lower pressure head; the arc radius R Upper part 2 of the first radian of the 2 nd upper press head is 5-10 mm smaller than the arc radius R Upper part 3 of the first radian of the 3 rd upper press head.
The situation that a plurality of groups of leveling devices are arranged can aim at the copper mesh close to the winding core, because the copper mesh warpage is more serious when the copper mesh is closer to the winding core of the copper mesh winding tape; the larger the number of copper meshes is, the more serious the copper mesh warpage is; the larger the diameter of copper wires of the braided copper net is, the more serious the copper net is warped; these can cause severe warpage of the processed copper mesh product, and multiple leveling actions are needed to perform leveling.
The leveling process is the same, after 1 st time of leveling, 1 st upward the pressure head under the cylinder drives, will pass through the copper mesh of 1 st time of leveling and convey 2 nd leveling station through negative pressure absorption and level, and 2 nd upward the pressure head under the cylinder drives, will pass through the copper mesh of 2 nd time of leveling and convey 3 rd leveling station through negative pressure absorption and level, until the leveling effect satisfies the requirement.
The above embodiments are merely preferred embodiments of the present utility model, and are not intended to limit the present utility model; although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
