Description

Technical Field

[0001] This utility model relates to the technical field of steel plate processing equipment, specifically a thick steel plate curved surface forming equipment. Background Technology

[0002] Steel plate bending forming involves applying external force to a steel plate using molds or mechanical equipment, causing it to undergo plastic deformation to obtain a workpiece of the desired shape and size. Its main purpose is to meet the needs of different industries for the shape and size of metal workpieces, improve material utilization, reduce production costs, and simultaneously improve the mechanical properties and surface quality of the workpiece. Among these methods, using hydraulic equipment to bend steel plates is a common method for forming curved surfaces.

[0003] To control the shape of the steel plate after bending, it is usually necessary to control the pressure and stroke of the hydraulic equipment. This requires the hydraulic equipment to be equipped with a relatively complex control system and sensor system, resulting in high operating costs and maintenance difficulties. At the same time, it also requires a large working space, which is difficult for small processing workshops to afford and is not conducive to widespread use. Therefore, to address the above problems, a thick steel plate curved surface forming equipment is proposed. Utility Model Content

[0004] The technical problem this utility model aims to solve is to provide a thick steel plate curved surface forming equipment. The hydraulic system of this steel plate processing equipment has a relatively simple structure, requiring only the hydraulic cylinder in the pressure gantry to apply pressure. The applied pressure is evenly distributed by several spring support members. When the pressure applied by the hydraulic cylinder increases, the stroke of the spring support members increases synchronously, and vice versa. The stroke information of the spring support members can be reflected by the scale indicator block and scale lines. Therefore, the operator can know the current pressure applied by the hydraulic cylinder and whether it has reached the rated value for bending processing. In summary, the degree of bending of the steel plate can be reflected through a simple structure, which facilitates the operator to control the start and stop of the hydraulic cylinder, greatly reducing the operating cost of the equipment. This solves the technical problem in the prior art that when it is necessary to obtain steel plates with a specified bending shape in batches, the hydraulic equipment usually needs to be equipped with a relatively complex control system and sensor system, which leads to high operating costs and maintenance difficulties, making it inconvenient for widespread use.

[0005] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0006] A thick steel plate curved surface forming device includes a support frame with an adjustable guide plate mounted on it. A sliding table is slidably mounted on the adjustable guide plate. Spring supports are detachably mounted on the sliding table, and rolling end rollers are installed between opposing spring supports to support the ends of the steel plate to be bent. A pressure gantry applies pressure to the middle of the steel plate to bend it. Each spring support has a scale indicator block with a marking groove, and the spring support has scale lines. The markings in the grooves correspond to the current travel of the spring support. The hydraulic system in this steel plate processing equipment has a relatively simple structure, with the pressure applied by the hydraulic cylinder being evenly distributed among several spring supports. When the pressure applied by the hydraulic cylinder increases, the stroke of the spring supports increases synchronously, and vice versa. The stroke information of the spring supports can be reflected by the scale indicator block and scale lines. Therefore, the operator can know the current pressure applied by the hydraulic cylinder and whether the rated value for bending processing has been reached. The structure of the above technical solution is relatively simple and has a low operating cost while achieving the control effect.

[0007] In one possible implementation, the spring support includes a base plate with limit blocks fixedly installed at both its upper and lower ends. A sliding rod is slidably installed in the limit block, and a connecting slider is fixedly installed on the sliding rod. A support spring is sleeved on the lower side of the connecting slider and fitted outside the sliding rod. In addition, a connecting shaft is bolted to the connecting slider and fixedly connected to the end of the plate end roller. The plate end roller supports the end of the steel plate. When the steel plate is bent under pressure, the plate end roller will push the connecting slider to overcome the resistance of the support spring and slide down. When the pressure increases, the connecting slider will continue to slide down. When the pressure decreases, the connecting slider will slide up under the thrust of the support spring. Based on the above technical solution, the magnitude of the pressure on the steel plate can be determined by the position of the connecting slider.

[0008] In one possible implementation, when the connecting slider is in contact with the upper limiting block, i.e., when the support spring is in its initial state, it is in a compressed state. The above technical solution can ensure that the support spring has a certain resistance in its initial state, making the whole device easy to use.

[0009] In one possible implementation, the scale indicator block is fixedly mounted on the upper limit block and is made of transparent material. The scale line is located on the upper part of the sliding rod. When the connecting slider slides, the sliding rod slides synchronously, and the corresponding scale in the marking groove changes synchronously. The operator can judge the current pressure by the scale information in the marking groove.

[0010] In one possible implementation, the adjustable guide plate includes a plate body with two guide rods fixedly arranged on its inner side. The sliding table is slidably arranged on the guide rods. Based on the above structure, the sliding table can slide freely along the guide rods, thereby adjusting the distance between the two plate end rollers. This makes it suitable for processing steel plates of different sizes. At the same time, by changing the support point, the bending shape of the steel plate under pressure can be adjusted to a certain extent.

[0011] In one possible implementation, a positioning screw is provided between the guide rods. Correspondingly, a through hole with a diameter larger than that of the positioning screw is provided on the sliding table. In addition, locking wheels that are threadedly connected to the positioning screw are provided on both sides of the sliding table. After the position of the sliding table is adjusted, the locking wheels on both sides are turned so that the locking wheels can clamp and fix the sliding table, thereby fixing the position of the sliding table and preventing it from sliding when the steel plate is pressed, which would affect the processing.

[0012] In one possible implementation, the pressure gantry includes a gantry body, in which a hydraulic cylinder is fixedly installed. A pressure frame is installed at the output shaft end of the hydraulic cylinder, and several symmetrically arranged pressure rollers are rotatably installed on it. The hydraulic cylinder can apply pressure to the steel plate through the pressure rollers, causing it to deform under pressure. In addition, the pressure rollers can reduce the friction between the steel plate and the pressure rollers.

[0013] In one possible implementation, the upper surface of the pressure frame is fixedly provided with several anti-bending ribs. This structure can enhance the bending strength of the pressure frame and prevent it from bending and deforming during pressurization. In addition, several symmetrically arranged guide rods are slidably arranged in the gantry body, and their bottom ends are fixedly connected to the upper surface of the pressure frame. The guide rods can guide the movement of the pressure frame and prevent it from deviating during the up and down movement.

[0014] In summary, this utility model has the following beneficial technical effects:

[0015] The hydraulic system in this steel plate processing equipment is relatively simple, requiring only the hydraulic cylinder in the pressure gantry to apply pressure. The applied pressure is evenly distributed among several spring supports. When the pressure applied by the hydraulic cylinder increases, the stroke of the spring supports increases synchronously, and vice versa. The stroke information of the spring supports can be reflected by the scale indicator block and scale lines. Therefore, the operator can know the current pressure applied by the hydraulic cylinder and whether the rated value for bending processing has been reached. In summary, the degree of bending of the steel plate can be reflected through a simple structure, making it easy for the operator to control the start and stop of the hydraulic cylinder and significantly reducing the operating cost of the equipment.

[0023] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0024] like Figure 1 - Figure 2As shown, this embodiment provides a thick steel plate curved surface forming device, including a support frame 1 on which an adjustable guide plate 2 is mounted. A sliding table 3 is slidably mounted on the adjustable guide plate 2. A spring support member 4 is detachably mounted on the sliding table 3, and rolling plate end rollers 5 are installed between opposite spring support members 4 to support the ends of the steel plate to be bent. A pressure gantry 6 is used to apply pressure to the middle of the steel plate to bend it. The spring support member 4 is equipped with a scale indicator block 7 with a marking groove 71, and the spring support member 4 is provided with a scale line 72. The scale in the marking groove 71 corresponds to the current position of the spring support member 4. The stroke corresponds to the pressure applied by the current pressurizing gantry 6. The hydraulic system in this steel plate processing equipment has a relatively simple structure. The pressure applied by the hydraulic cylinder 62 is evenly distributed by several spring support members 4. When the pressure applied by the hydraulic cylinder 62 increases, the stroke of the spring support members 4 increases synchronously, and vice versa. The stroke information of the spring support members 4 can be reflected by the scale indicator block 7 and the scale line 72. Therefore, the operator can know the current pressure applied by the hydraulic cylinder 62 and whether it has reached the rated value for bending processing. The structure of the above technical solution is relatively simple and has a low operating cost while achieving the control effect.

[0025] like Figure 3 - Figure 4 As shown, the spring support 4 includes a base plate 41, with limit blocks 42 fixedly installed at both its upper and lower ends. A sliding rod 43 is slidably installed in the limit block 42, and a connecting slider 44 is fixedly installed on the sliding rod 43. A support spring 45 is sleeved on the lower side of the connecting slider 44 and is sleeved on the sliding rod 43. In addition, a connecting shaft 46 is bolted to the connecting slider 44 and fixedly connected to the end of the plate end roller 5. The plate end roller 5 supports the end of the steel plate. When the steel plate is bent under pressure, the plate end roller 5 will push the connecting slider 44 to overcome the resistance of the support spring 45 and slide down. When the pressure increases, the connecting slider 44 will continue to slide down. When the pressure decreases, the connecting slider 44 will slide up under the thrust of the support spring 45. Based on the above technical solution, the magnitude of the pressure on the steel plate can be determined by the position of the connecting slider 44.

[0026] The scale indicator block 7 is fixedly mounted on the upper limit block 42 and is made of transparent material. The scale line 72 is located on the upper part of the sliding rod 43. When the connecting slider 44 slides, the sliding rod 43 slides synchronously. Correspondingly, the scale in the marking groove 71 will change synchronously. The operator can judge the current pressure by the scale information in the marking groove 71.

[0027] In addition, when the connecting slider 44 is in contact with the upper limiting block 42, that is, when the support spring 45 is in its initial state, it is in a compressed state. The above technical solution can ensure that the support spring 45 has a certain resistance in its initial state, making the whole device easy to use.

[0028] like Figure 2 - Figure 3 As shown, the adjustable guide plate 2 includes a plate body 21, on which two guide rods 22 are fixedly arranged on the inner side. The sliding table 3 is slidably arranged on the guide rods 22. Based on the above structure, the sliding table 3 can slide freely along the guide rods 22, thereby adjusting the distance between the two plate end rollers 5. This makes it suitable for processing steel plates of different sizes. At the same time, by changing the support point, the bending shape of the steel plate under pressure can be adjusted to a certain extent.

[0029] In addition, a positioning screw 23 is provided between the guide rods 22. Correspondingly, a through hole with a diameter larger than that of the positioning screw 23 is provided on the sliding table 3. Furthermore, locking wheels 24 that are threadedly connected to the positioning screw 23 are provided on both sides of the sliding table 3. After the position of the sliding table 3 is adjusted, the locking wheels 24 on both sides are turned so that the locking wheels 24 can clamp and fix the sliding table 3, thereby fixing the position of the sliding table 3 and preventing it from sliding when the steel plate is pressed, which would affect the processing.

[0030] like Figure 5 As shown, the pressure gantry 6 includes a gantry body 61, in which a hydraulic cylinder 62 is fixedly installed. A pressure frame 63 is installed at the output shaft end of the hydraulic cylinder 62, and several symmetrically arranged pressure rollers 64 are rotatably mounted on it. The hydraulic cylinder 62 can apply pressure to the steel plate through the pressure rollers 64, causing it to deform under pressure. In addition, the pressure rollers 64 can reduce the friction between the steel plate and the pressure frame. Furthermore, several anti-bending ribs 65 are fixedly provided on the upper end face of the pressure frame 63. This structure can enhance the bending strength of the pressure frame 63 and prevent it from bending and deforming during pressure application. In addition, several symmetrically arranged guide rods 66 are slidably arranged in the gantry body 61, and their bottom ends are fixedly connected to the upper end face of the pressure frame 63. The guide rods 66 can guide the movement of the pressure frame 63 and prevent it from deviating during vertical movement.

[0031] The working principle and usage process of this utility model:

[0032] During processing, the steel plate is lifted by the hoisting equipment and placed on the plate end roller 5 on one side. Then, the steel plate is pulled to the plate end roller 5 on the other side until both ends of the steel plate overlap the plate end roller 5. Alternatively, the steel plate is transported to the plate end roller 5 by a conveyor belt. Then, the hydraulic cylinder 62 works to apply pressure, causing the steel plate to bend and be shaped under pressure.

[0033] The hydraulic system in this steel plate processing equipment is relatively simple. It only requires the hydraulic cylinder 62 in the pressure gantry 6 to apply pressure. The applied pressure is evenly distributed by several spring support members 4. When the pressure applied by the hydraulic cylinder 62 increases, the stroke of the spring support members 4 increases synchronously, and vice versa. The stroke information of the spring support members 4 can be reflected by the scale indicator block 7 and the scale line 72. Therefore, the operator can know the current pressure applied by the hydraulic cylinder 62 and whether it has reached the rated value for bending processing. In summary, the bending degree of the steel plate can be reflected through a simple structure, which makes it easy for the operator to control the start and stop of the hydraulic cylinder 62 and greatly reduces the operating cost of the equipment.

[0034] The visualization of the stroke information of the aforementioned spring support 4 is specifically manifested as follows: when the steel plate is bent under pressure, the plate end roller 5 will push the connecting slider 44 to overcome the resistance of the support spring 45 and slide down. When the pressure increases, the connecting slider 44 will continue to slide down, while when the pressure decreases, the connecting slider 44 will slide up under the thrust of the support spring 45. When the connecting slider 44 slides, the sliding rod 43 slides synchronously, and the corresponding scale in the marking groove 71 will change synchronously. The operator can judge the current pressure by the scale information in the marking groove 71.

[0035] In addition, the sliding table 3 can slide freely along the guide rod 22, thereby adjusting the distance between the two plate end rollers 5, which is suitable for processing steel plates of different sizes. At the same time, the bending shape of the steel plate under pressure can be adjusted to a certain extent by changing the support point.

[0036] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
