Description

Technical Field

[0001] The invention relates to the technical field of rolling, in particular to a rolling device for high and low voltage switch cabinet parts. Background Art

[0002] As the name implies, high and low voltage switchgear is equipment for connecting high voltage or low voltage cables. Generally, power supply bureaus and substations use high voltage cabinets, which are then stepped down by transformers to low voltage cabinets, and then to distribution boxes for various power users. The cabinets are nothing more than some protective devices such as switches and circuit breakers assembled into one electrical equipment. Among them, the cabinets of high and low voltage switchgear are generally composed of various alloy plates, and rolling is a method often used to produce alloy plates. Rolling is a metal processing process, which refers to the pressure processing method of passing metal billets through the gap between a pair of rotating rollers, which reduces the cross-section of the material and increases the length due to the compression of the rollers. Rolling is the most commonly used production method for steel, mainly used to produce profiles, plates, and pipes, divided into hot rolling and cold rolling.

[0003] Through patent search, it was found that a rolling device for high and low voltage switchgear components with announcement number CN117900272B is used. The metal billet is transferred to the rolling mechanism for rolling through a supporting mechanism. The metal billet can be rolled by multiple rollers. Among them, since the center point of the roller is at different straight line distances from multiple sides of the adjusting part, when the adjusting part is controlled by the sliding rotation component to rotate to different edges and abut against the moving block, the adjusting part can be used to limit the width of the metal billet with different rolling thickness requirements. The sliding rotation component can also control the adjustment part to move along the roller, which can meet the adjustment of different rolling widths.

[0004] The above-mentioned comparative document changes the distance between the two groups of rollers on the upper line by adjusting the angle of a multi-faceted adjustment member. However, due to the multi-faceted design, there are gears for adjusting the spacing between the upper and lower groups of rollers, and each gear corresponds to a group of prismatic surfaces. Therefore, the adjustment of the two groups of rollers cannot be steplessly adjusted, which results in certain limitations in the adjustment of the spacing between the two groups of rollers.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The present application replaces the prismatic structure in the comparative document with an elliptical limit adjustment piece. Through the meshing drive of the worm part and the worm wheel part, the distance between the limit adjustment piece and the lower roller support block can be steplessly adjusted through the rotation of the limit adjustment piece. In this way, the spacing adjustment of the top roller and the bottom roller is more precise, and more precise roller operation can be achieved, thereby improving practicality and scope of application. The position of the limit adjustment piece outside the top roller is adjusted by adjusting the meshing of the screw part with the meshing sleeve. Since the frequency of adjustment of the spacing of the limit adjustment piece is low, a spiral manual adjustment method is adopted, which can reduce the cost of use and facilitate subsequent maintenance.

[0017] The present application also uses the drive of a hydraulic cylinder to realize the reciprocating movement of the lower roller support block on one side of the limit adjustment member. In order to reduce the gap between the limit adjustment member and the support block column, multiple groups of longitudinally distributed auxiliary push plates can be filled in the gap, and the upper and lower groups of auxiliary push plates are combined by positioning plugs and reinforcing the socket parts. The combined auxiliary push plates have stronger integrity and are more stable when the auxiliary push plates are moved under force, so that the metal billet is more efficient and more stable when moving forward to the rolling rollers.

[0018] In the present application, the longer the length of the screw handle that penetrates into the gap between the support block column and the limit adjustment member, the more auxiliary push plates can be placed, so that the gap can be filled with a sufficient number of auxiliary push plates to maximize the filling, further improving the ability to push the metal blank, and the installation and position adjustment of the screw handle can be quickly adjusted by the descent of the positioning bar and the limit penetrating rod, making the entire device more convenient for subsequent adjustment operations, reducing the use of electrical equipment, and being more practical.

[0019] After the position adjustment of the limit adjustment member is completed, the present application can provide support for the limit adjustment member by supporting the side of the limit adjustment member through the support block portion, so as to avoid the thread being withdrawn due to excessive rolling intensity during the rolling process, thereby improving the stability of the limit adjustment member in restraining the metal blank and reducing the damage rate.

[0020] The present application can penetrate a penetration column in the limit penetration hole, and can transversely penetrate a multi-faceted multi-faceted penetration rod in the multi-faceted transverse penetration hole, so that the side opening of the sleeve can be sleeved on the outside of the multi-faceted penetration rod, so that the cleaning scraper can be against the surface of the bottom roller and the top roller, and the surface of the bottom roller and the top roller in a rotating state can be cleaned and scraped, which greatly reduces the influence of particles and impurities on the rolling process, and the two adjacent groups of multi-faceted sleeves adopt a transversely plug-in splicing structure, and different numbers of multi-faceted sleeves can be freely disassembled and assembled according to the spacing adjustment of the two groups of limit adjustment parts, which is convenient for subsequent adjustment and use.

In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0035] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] See also Figure 1-12 , including: a top roller 4, a bottom roller 3 arranged parallel to the top roller 4, a lifting adjustment plate 2 installed at both ends of the bottom roller 3 and the top roller 4, an upper roller motor 13 for driving the top roller 4 to rotate, a lower roller motor 14 for driving the bottom roller 3 to rotate, a lower roller support block 15 slidably sleeved on the outside of the bottom roller 3, and a support block column 17 fixedly connected to one end of the lower roller support block 15. The metal billet to be rolled enters between the bottom roller 3 and the top roller 4. Since the gap between the bottom roller 3 and the top roller 4 is smaller than the thickness of the metal billet, the bottom roller 3 and the top roller 4 rotate in opposite directions driven by the upper roller motor 13 and the lower roller motor 14, and the metal billet of the high and low voltage switch cabinet parts with larger thickness can be pressed, thereby completing the rolling operation.

[0038] The limit adjustment member 6 is slidably sleeved outside the top roller 4. The limit adjustment member 6 adopts a special elliptical structure, the upper part of which is half of a circle and the lower part is half of an ellipse. A lower roller support block 15 is arranged below the limit adjustment member 6. Due to the special appearance of the limit adjustment member 6, when different positions of the outer part of the limit adjustment member 6 contact the upper part of the lower roller support block 15, the distance between the bottom roller 3 and the top roller 4 can be adjusted. Moreover, the shape design of the limit adjustment member 6 determines that as the limit adjustment member 6 rotates, the distance between the bottom roller 3 and the top roller 4 can be adjusted steplessly. Compared with the comparative document, the specific adjustment The adjustment is more precise, the end surface of the limit adjustment member 6 close to the lifting adjustment plate 2 is connected with an adjusting screw portion 11, the front end of the adjusting screw portion 11 is embedded in the groove on the surface of the limit adjustment member 6 and can be rotated and cannot be separated, the adjusting screw portion 11 can be used as a way to push the limit adjustment member 6 to move, a worm gear portion 7 is installed between the limit adjustment member 6 and the lifting adjustment plate 2, a meshing sleeve 9 is fixed in the worm gear portion 7, the adjusting screw portion 11 is meshed and penetrated in the meshing sleeve 9, and the worm portion 8 is meshed and connected above the worm gear portion 7. Since the meshing sleeve 9 is meshed and connected with the adjusting screw portion 11, and the meshing sleeve 9 is fixed on the worm The surface of the wheel portion 7 is formed by rotating the adjusting screw portion 11, so when the end of the screw portion 11 is rotated, the limit adjustment member 6 can be pushed by the rotation of the adjusting screw portion 11, so as to adjust the position of the limit adjustment member 6 outside the top roller 4, thereby changing the distance between the two oppositely distributed groups of limit adjustment members 6, and rolling metal blanks with different widths. The motor at one end of the worm portion 8 can drive the worm portion 8 to rotate, and the worm portion 8 can drive the worm wheel portion 7 to rotate after the rotation of the worm portion 8. After the rotation of the worm wheel portion 7, the meshing sleeve 9 and the adjusting screw portion 11 can be driven to rotate, so that the limit adjustment member 6 rotates, and the lifting mechanism on one side of the worm wheel portion 7 A C-shaped screw moving groove 10 is opened on the surface of the lifting adjustment plate 2, so that the adjusting screw part 11 can pass through the screw moving groove 10 and extend to the other side of the lifting adjustment plate 2, and the screw moving groove 10 does not affect the normal rotation of the adjusting screw part 11. At the same time, in order to improve the rotation stability of the worm gear part 7, an annular groove is opened on the end face of the lifting adjustment plate 2 close to the worm gear part 7, and a limiting ring groove 16 is slidably connected in the annular groove. The other end of the limiting ring groove 16 is fixed to the surface of the worm gear part 7. During the rotation of the worm gear part 7, the limiting ring groove 16 slides in the annular groove to improve the position of the worm gear part 7 and the rotation stability.Since one end of the adjusting screw portion 11 is connected to the limit adjustment member 6, the distance between the top roller 4 and the bottom roller 3 can be changed by rotating the worm gear portion 7, and a supporting bottom plate 1 is arranged below the lifting adjustment plate 2, and the supporting bottom plate 1 is connected to the lifting adjustment plate 2 through a hydraulic cylinder. Therefore, when the limit adjustment member 6 rotates, the position of the lifting adjustment plate 2 and the supporting bottom plate 1 can be adjusted so that the lower end surface of the limit adjustment member 6 is always in contact with the upper part of the lower roller support block 15, and different positions of the limit adjustment member 6 contact the lower roller support block 15, so that the distance between the top roller 4 and the bottom roller 3 can be accurately adjusted, thereby realizing stepless adjustment of the distance between the bottom roller 3 and the top roller 4.

[0039] The column longitudinal groove 18 is provided inside the support block column 17, and the support block column 17 is provided with an insertion transverse groove 19 connected to the column longitudinal groove 18. The insertion transverse groove 19 is arranged in multiple groups at equal intervals along the longitudinal direction of the column longitudinal groove 18. An adjustment transverse plate 21 is horizontally penetrated in the groove of the insertion transverse groove 19, and a transverse plate convex plate 22 adapted to the side opening of the insertion transverse groove 19 is fixed on the side wall of the adjustment transverse plate 21. An opening extending to one side is provided in the groove of the insertion transverse groove 19, so that the insertion transverse groove 19 and the opening combination form a convex groove structure, so that the combined structure of the transverse plate convex plate 22 and the adjustment transverse plate 21 can move laterally in the groove of the insertion transverse groove 19, and at the same time, the width of the insertion transverse groove 19 and the opening combination is the same as the slot width of the column longitudinal groove 18, so that the transverse plate convex plate 22 and the adjustment transverse plate 21 can directly extend from the groove top of the column longitudinal groove 18, and enter the groove of each insertion transverse groove 19 laterally;

[0040] The convex plate groove 26 is provided inside the transverse plate convex plate 22, and the support block column 17 is longitudinally placed on one side of the limit adjustment member 6. Due to the special shape of the limit adjustment member 6, a gap is left between the limit adjustment member 6 and the support block column 17, and an auxiliary push plate 27 is placed in the gap. A positioning plug 29 adapted to the convex plate groove 26 is fixed at the bottom of the auxiliary push plate 27, and a reinforcement socket portion 30 identical to the convex plate groove 26 is provided at the top of the auxiliary push plate 27. The upper and lower sets of auxiliary push plates 27 are combined by plugging the positioning plug 29 with the reinforcement socket portion 30. Due to the special structure of the limit adjustment member 6, the limit The size of the gap between the adjusting member 6 and the support block column 17 will change, and the gap width at the lower position will be larger, so the adjusting cross plate 21 at the bottom layer can be extended longer from the insertion groove 19, while the extension distance of the upper adjusting cross plate 21 gradually decreases, and the positioning plug 29 that can be fixedly connected to the lower part of the auxiliary push plate 27 can be longitudinally sleeved on the top of the convex plate groove 26, so that the front end of the auxiliary push plate 27 is flush with the surface of the support block column 17, so that the auxiliary push plate 27 and the support block column 17 play the same role, and the metal blank overflowing to both sides is pressed between the two sets of limit adjusting members 6, and In order to reinforce the auxiliary push plates 27 distributed up and down, the positioning plug 29 fixedly connected to the bottom of the upper auxiliary push plate 27 can pass through the upper convex plate groove 26 and then extend downward and be inserted into the reinforcement socket portion 30, so that the upper and lower sets of auxiliary push plates 27 can be reinforced, thereby improving the integrity and strength of the entire auxiliary push plate 27 combination. One end of the auxiliary push plate 27 is spirally combined with a contact ball portion 28, and the contact ball portion 28 is composed of two parts, one of which is a screw rod, which is connected to the screw hole on the side of the auxiliary push plate 27, so that the contact ball portion 28 is vertically installed on one side of the auxiliary push plate 27, and the contact ball portion 28 is vertically installed on the side of the auxiliary push plate 27. The other part of the ball portion 28 is a universal ball, which adopts a metal shell to be sleeved on the outside of the metal ball, so that the metal ball can rotate freely and cannot fall off, so that the contact ball portion 28 on each plane is against the surface of the limit adjustment member 6, and the surface of the entire support block column 17 is connected by a hydraulic cylinder. Through the connection of the hydraulic cylinder, the support block column 17 is reciprocated radially outside the bottom roller 3, and the metal blank that is about to overflow is pressed inward. Through the action of the metal ball at the front end of the contact ball portion 28, the auxiliary push plate 27 is made as close to the surface of the limit adjustment member 6 as possible, which greatly reduces wear and improves service life.

[0041] The positioning bottom groove 20 is provided at the bottom of the groove of the column longitudinal groove 18, and a positioning strip 25 is inserted in the groove of the positioning bottom groove 20. The top of the positioning strip 25 is fixedly provided on the top cover plate 23. The surface of the support block column 17 is longitudinally provided with a socket adapted to the convex plate groove 26. The bottom of the top cover plate 23 is fixedly provided with a limit rod portion 24 which is inserted into the socket and the convex plate groove 26. After the position adjustment of the adjustment cross plate 21 is completed, it can be longitudinally inserted into the positioning bottom groove 20 by inserting the cross groove 19. At the same time, the upper roller motor 13 at the top of the positioning strip 25 is buckled on the top of the support block column 17. The positioning strip 25 can be used to adjust the position of the cross plate 21. The adjusting cross plate 21 will not fall off laterally by resisting against it, and at the same time, the limiting through rod portion 24 can be lowered to be inserted into the convex plate groove 26, so as to constrain the front and rear positions of multiple groups of adjusting cross plates 21 distributed at upper and lower intervals, thereby realizing the rapid locking of the position of the adjusting cross plate 21. Through this structure, the subsequent adjustment and locking of the position of the adjusting cross plate 21 can be greatly facilitated, and the structural design is simple, and the production and use costs are low. Moreover, the opening of the convex plate groove 26 can be adapted to the limiting through rod portion 24, the reinforcement socket portion 30 and the positioning plug block 29 at the same time, and the structure has strong versatility and is more convenient to produce and use.

[0042] The end of the adjusting screw part 11 away from the limit adjusting member 6 is fixedly provided with a screw handle part 12. The end of the screw handle part 12 is rotatably sleeved with a linkage connecting plate 31, and the other end of the linkage connecting plate 31 is sleeved with a driven slide 32, and the front end side wall of the driven slide 32 is fixedly provided with a support block part 43, and the surface of the support block part 43 is provided with a block bar attached to the surface of the limit adjusting member 6. After the positions of the driven slide 32 and the support block part 43 are locked by the slide positioning block 34, the support block part 43 can support the limit adjusting member 6, improve the support stability of the limit adjusting member 6, and reduce the occurrence of the slipping of the adjusting screw part 11. The surface of the lifting adjustment plate 2 is provided with a rectangular hole allowing the driven slide 32 to slide through. The side wall of the driven slide plate 32 is provided with slide plate limiting holes 33 arranged at equal intervals, and the lifting and adjusting plate 2 is slidably installed with a slide plate positioning block 34 that can be inserted into the groove of the slide plate limiting hole 33. The end of the screw handle 12 is cylindrical and embedded in the end of the linkage connecting plate 31, so that when the screw handle 12 rotates, it can drag the linkage connecting plate 31 to move radially. Therefore, as the screw handle 12 rotates, the adjustment screw part 11 moves and the linkage connecting plate 31 is also driven to move synchronously, so that the driven slide plate 32 moves parallel to one side of the adjustment screw part 11, and the driven slide plate 32 can be locked by being inserted into the groove of the slide plate limiting hole 33 through the slide positioning block 34, so that the position of the linkage connecting plate 31 and the adjustment screw part 11 can be locked synchronously.

[0043] The limiting hole 33 of the last slide plate passes through the limiting penetration hole 35 longitudinally, and a penetration column 36 is penetrated in the limiting penetration hole 35. A penetration column 36 has a multi-faceted transverse penetration hole 37 transversely formed on the surface of the penetration column 36. A larger block is fixed to the outside of the penetration column 36, so that a part of the penetration column 36 can pass through the limiting penetration hole 35 to extend to the bottom of the driven slide plate 32, and the other part remains above the driven slide plate 32. The two groups of multi-faceted transverse penetration holes 37 are respectively located at the upper and lower parts of the penetration column 36. A multi-faceted penetration rod 38 can be transversely penetrated in each group of multi-faceted transverse penetration holes 37. An opening is provided at the end of the multi-faceted penetration rod 38, and a multi-faceted sleeve 39 is longitudinally inserted into the opening so that the multi-faceted penetration rod 38 cannot be separated from the multi-faceted transverse penetration hole 37. After installation, the multi-faceted penetration rod 38 is located on one side of the bottom roller 3 and the top roller 4, and does not affect the normal rolling operation of the bottom roller 3 and the top roller 4 on the metal blank.

[0044] A multi-faceted sleeve 39 is provided on the outer sleeve of the multi-faceted penetration rod 38, and a cleaning scraper 40 is fixedly provided on the side wall of the multi-faceted sleeve 39. A sleeve side opening 41 is provided at one end of the multi-faceted sleeve 39, and a sleeve side insertion rod 42 which is plugged and matched with the sleeve side opening 41 is provided at the other end of the multi-faceted sleeve 39. Since the distance between the oppositely distributed limit adjustment members 6 can be adjusted, a detachable split multi-faceted sleeve 39 and a cleaning scraper 40 are used for cleaning the surfaces of the bottom roller 3 and the top roller 4. The sleeve side insertion rod 42 on the side wall of the multi-faceted sleeve 39 can be inserted into the sleeve side opening 41 groove of the multi-faceted sleeve 39 on the other side, thereby completing the combination of the two sets of multi-faceted sleeves 39. The cleaning scraper 40 after the combination is In the same way, due to the multi-faceted shape of the multi-faceted penetrating rod 38, the multi-faceted sleeve 39 can be directly locked after adjusting the angle, so that the bottom roller 3 and the top roller 4 can be cleaned conveniently by using the cleaning scraper 40. The entire device transfers the metal billet to between the bottom roller 3 and the top roller 4 by the transmission of the material conveying roller 5. The bottom roller 3 and the top roller 4 can roll the metal billet with thicker thickness by rotating. In order to prevent the metal billet from overflowing from both sides of the limit adjustment member 6 during the rolling process, the lower roller support block 15 and the support block column 17 are repeatedly moved radially on one side of the limit adjustment member 6 through hydraulic drive, so that the billet that is about to move outward can be squeezed between the limit adjustment members 6.
