Description

Technical Field

[0001] The utility model relates to the technical field of plate flattening, and particularly relates to a steel plate flattening machine for construction engineering. Background Technique

[0002] Steel plates are flat steel plates cast from molten steel and pressed after cooling, which are formed by direct rolling or shearing from wide steel strips; in construction engineering, a certain number and different thicknesses of plates are required, mainly thin steel plates and medium-thick steel plates, which are used in different positions of the building; if the overall plate is uneven when used in the exterior of the construction project, it will seriously affect the consistency and aesthetics of the construction project. During transportation, the steel plate may be bent due to external forces or improper handling, and it is necessary to flatten the steel plate before use to ensure its flatness.

[0003] After retrieval, a steel plate flattening device for construction engineering with a publication number such as CN210387044U, by increasing the guiding and traction effects, is beneficial for the steel plate to travel along the vertical direction of the pressure roller to ensure the best flattening effect. However, for small-scale flattening requirements or situations with limited budgets, manual flattening may be a more economical option, and manual flattening is more conducive to control to ensure the depth of flattening. The operator can make real-time adjustments according to the actual situation to achieve the best flattening effect. Content of the Utility Model

[0009] Preferably, a first mounting seat is provided on one side of the fixed plate away from the driving member, and the first mounting seat is located at the top of the shaft rod.

Detailed implementation manners

[0026] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the present utility model will be further introduced in detail below with reference to the accompanying drawings.

[0027] An embodiment of the present utility model discloses a steel plate flattening machine for construction engineering.

[0028] The present utility model provides a Figures 1-5 as shown in

[0029] a steel plate flattening machine for construction engineering, which includes a base (1), a support plate (2) is welded on the top of the base (1), two fixing plates (3) are symmetrically welded on the outer wall of the support plate (2), a shaft rod (4) is rotatably connected between the two fixing plates (3), a driving member (5) is installed on the shaft rod (4), a pressing block (6) is located at the bottom of the driving member (5), a steel plate body (7) is placed on the base (1), and the steel plate body (7) is located between the pressing block (6) and the base (1).

[0030] Place the steel plate body 7 on the base 1. The operator holds the handle 503 and pulls down the two bumps 501. The outer wall of the bump 501 abuts against the top surface of the pressing block 6, pushing the pressing block 6 to move downward and approach the steel plate body 7. According to the thickness and bending degree of the steel plate body 7, by controlling the rotation angle of the bump 501, the flattening depth of the steel plate body 7 can be controlled to achieve the best flattening effect.

[0031] To improve the practicality of the present utility model, as Figure 1 shown, first mounting seats 8 are provided on the sides of the fixing plate 3 away from the driving member 5, and the first mounting seats 8 are located at the tops of the shaft rods 4. Second mounting seats 9 are symmetrically provided on the top of the pressing block 6. The second mounting seats 9 and the first mounting seats 8 have the same structure, both consisting of an n-shaped seat and a rotating block inside it. An elastic member 10 is connected between two adjacent first mounting seats 8 and second mounting seats 9.

[0032] To conform to the actual situation, the elastic member 10 is preferably a spring. After the driving member 5 pushes the pressing block 6 downward to flatten the steel plate body 7, the driving member 5 rotates in the reverse direction around the axis of the shaft rod 4. Under the elastic action of the elastic member 10, the pressing block 6 is driven to return to the initial position, facilitating the flattening of the next steel plate body 7.

[0033] As Figure 1 shown, both ends of the shaft rod 4 are movably penetrated through the wall body of the fixing plate 3, and tightening nuts 11 are threadedly connected to both ends of the shaft rod 4; by turning the tightening nuts 11, the friction force between the tightening nuts 11 and the side wall of the fixing plate 3 can be adjusted, so that the driving member 5 can fix its angle after rotation, facilitating the fixing of the driving member 5 to drive the pressing block 6 to reset as a whole.

[0034] As Figure 5 shown, a heating cavity is formed inside the pressing block 6, and an electric heating wire 16 is installed in the heating cavity. The electric heating wire 16 is electrically connected to an external power supply through a wire and a control switch.

[0035] The electric heating wire 16 preheats the whole pressing block 6. When the bottom surface of the pressing block 6 fits against the top surface of the steel plate body 7, the steel plate body 7 is more likely to deform and be flattened.

[0036] Finally, to improve the functionality of the present utility model, as Figure 3 、 Figure 4 shown, vertical chutes 12 are formed on the wall body of the support plate 2. A slider 13 is integrally formed and connected to the outer wall of the pressing block 6, and the slider 13 is slidably connected in the vertical chutes 12 to improve the stability of the pressing block 6 when moving up and down; a number of through holes 14 are linearly formed on one side of the vertical chutes 12, and a positioning pin 15 is inserted into one of the through holes 14.

[0037] Before the driving member 5 pushes the lower pressing block 6 to move downward, according to the actual thickness of the steel plate body 7 to be flattened, the positioning pin 15 is inserted into the corresponding through hole 14 to limit the downward movement distance of the lower pressing block 6, avoiding over-flattening the steel plate body 7 and preventing the crystal grain structure of the steel plate body 7 from becoming finer and more irregular, thereby increasing its brittleness and fragility.

[0038] Only some exemplary embodiments of the present invention have been described by way of illustration above. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
