The bending machine processes the steel plates by stamping to bend the steel plates into various shapes. The heavy-duty steel plate bending machine is a large-scale steel plate processing equipment, mainly for large-sized and heavy-weight steel plates.

[0003] The traditional way of fixing steel plates in bending machines is mostly to use downward clamping fixtures to fix the steel plates, but the horizontal direction of the steel plates is not effectively restricted, which makes them prone to deviation and affects the processing effect of the bending machine. Utility Model Content

[0008] The telescopic working platform body is provided with a telescopic clamping assembly, which is used to fix the steel plate to be bent. The telescopic clamping assembly includes a compression telescopic push rod, a tension spring, a gantry, a slide rail, a first slide sleeve, an L-shaped slide rod, a guide groove plate and an inclined guide groove;

[0009] The telescopic clamping assembly also includes a gantry, which is fixedly connected to the lower fixed block, the slide rail is slidably connected between the two vertical rods of the gantry, the first slide sleeve is slidably connected to the slide rail, the lower surface of the first slide sleeve is fixedly connected to the slide groove rail, and multiple sliders are slidably connected in the slide groove rail.

[0015] (3) Beneficial effects

[0016] Compared with the prior art, the present invention provides a telescopic working platform for a steel plate bending machine, which has the following beneficial effects:

[0017] 1. The telescopic working platform for the steel plate bending machine can make multiple L-shaped slide bars expand outward at the same time by the fixed column being guided by the inclined guide groove when following the upward movement. At this time, the L-shaped slide bar will drive the slider to expand outward at the same time through the second sliding sleeve. The W-shaped rubber pad can firmly fix the processed steel plate when it expands outward synchronously after contacting the steel plate, so that the steel plate can obtain pulling force on both sides and be pressed downward at the same time. This avoids the problem that the horizontal direction of the steel plate cannot be restricted when a single downward clamping fixture is used to fix the steel plate in the traditional way, which is easy to deviate and affects the processing effect of the bending machine.

[0018] 2. The telescopic working platform for the steel plate bending machine can expand and move separately through multiple L-shaped sliding rods set in the telescopic clamping assembly. This allows bending to be performed even when there are impurities or potholes on the surface of the steel plate, resulting in uneven thickness. The fixed area of ​​the steel plate can also be effectively fixed, avoiding unstable clamping caused by uneven thickness.

[0019] 3. The telescopic working platform for the steel plate bending machine can adjust the position of the first sliding sleeve left and right on the slide rail by screwing the positioning nut to adapt to the fixation of steel plates of different sizes and shapes, thereby improving the applicability of steel plate processing.

[0028] See also Figure 1-3The utility model provides a new technical solution: a telescopic working platform for a steel plate bending machine, comprising a telescopic working platform body 1, the supporting legs of the telescopic working platform body 1 are electric telescopic table legs that can be automatically raised and lowered, a feeding conveyor belt assembly for placing steel plates is provided on the telescopic working platform body 1, a lower fixing block 3 is fixedly connected to the telescopic working platform body 1, and the lower fixing block 3 is located on one side of the working area of ​​the steel plate bending machine;

[0029] A telescopic clamping assembly is provided on the telescopic working platform body 1, which is used to fix the steel plate to be bent. The telescopic clamping assembly includes a compression telescopic push rod 2, a tension spring 4, a gantry 5, a slide rail 7, a first slide sleeve 8, an L-shaped slide rod 11, a guide groove plate 13 and an inclined guide groove 14;

[0030] The telescopic clamping assembly also includes a gantry 5, which is fixedly connected to the lower fixed block 3, a slide rail 7 that is slidably connected between the two vertical rods of the gantry 5, a first slide sleeve 8 that is slidably connected to the slide rail 7, and a slide groove rail 9 that is fixedly connected to the lower surface of the first slide sleeve 8, in which a plurality of sliders 10 are slidably connected.

[0031] Furthermore, outer surfaces of the plurality of sliders 10 are fixedly connected to second sliding sleeves 12 , and the plurality of L-shaped sliding rods 11 are slidably connected in corresponding second sliding sleeves 12 .

[0032] Furthermore, the outer surface of the second sliding sleeve 12 is fixedly connected to a tension spring fixing column 16 , and the upper end of the vertical plate of the L-shaped sliding rod 11 is fixedly connected to a fixing column 15 .

[0033] Furthermore, a plurality of tension springs 4 are fixedly connected between corresponding fixing columns 15 and tension spring fixing columns 16 , and the lower surface of the horizontal plate of the L-shaped slide bar 11 is fixedly connected with a W-shaped rubber pad 17 for increasing friction.

[0034] Furthermore, the guide groove plate 13 is fixedly connected to the outer surface of the first sliding sleeve 8, and multiple inclined guide grooves 14 are opened on the outer surface of the guide groove plate 13. The spacing between the multiple inclined guide grooves 14 is opened in a gradually decreasing manner, and the ends of the multiple fixed columns 15 away from the tension spring 4 are all slidably connected to the inner walls of the corresponding inclined guide grooves 14.

[0035] Furthermore, the two compression and telescopic push rods 2 are fixedly mounted on the lower surface of the horizontal plate of the gantry 5, and the output ends of the compression and telescopic push rods 2 are fixedly connected to the first sliding sleeve 8, on which a positioning nut 6 for tightening the slide rail 7 is threadedly connected.

[0036] Furthermore, when in use, the steel plate can be moved to the bottom of the gantry 5 by the feed conveyor belt assembly provided on the telescopic working platform body 1. At this time, by starting the two compression telescopic push rods 2, the two compression telescopic push rods 2 can synchronously drive the first slide sleeve 8 and the slide rail 7 to move downward together until the lower surfaces of the multiple L-shaped slide rods 11 can contact the processed steel plate. At this time, the L-shaped slide rod 11 will be affected by the contact force of the W-shaped rubber pad 17 and the steel plate, and move upward. At this time, the fixed column 15 is guided by the inclined guide groove 14 when following the upward movement. The directional action can cause multiple L-shaped slide bars 11 to expand outward at the same time, and at this time the L-shaped slide bar 11 will drive the slider 10 to expand outward at the same time laterally through the second slide sleeve 12. After contacting the steel plate, the W-shaped rubber pad 17 can expand outward synchronously and firmly fix the processed steel plate, which enables the steel plate to obtain pulling force on both sides while being pressed downward at the same time. This avoids the problem that the horizontal direction of the steel plate cannot be restricted when a single downward clamping fixture is used to fix the steel plate in the traditional way, which is easy to deviate and affect the processing effect of the bending machine.

[0037] Furthermore, by screwing the positioning nut 6, the position of the first sliding sleeve 8 can be adjusted left and right on the slide rail 7 to adapt to the fixation of steel plates of different sizes and shapes, thereby improving the applicability of steel plate processing;

[0038] The multiple L-shaped sliding rods 11 set in the telescopic clamping assembly can expand and move separately, which makes it possible to bend the steel plate when there are impurities or potholes on the surface, resulting in uneven thickness. The area where the steel plate is fixed can also be effectively fixed, avoiding unstable clamping caused by uneven thickness.

[0039] Working principle: When in use, the feed conveyor belt assembly set on the telescopic working platform body 1 can move the steel plate to the bottom of the gantry 5. At this time, by starting the two compression telescopic push rods 2, the two compression telescopic push rods 2 can synchronously drive the first slide sleeve 8 and the slide rail 7 to move downward until the lower surfaces of multiple L-shaped slide bars 11 can contact the processed steel plate. At this time, the L-shaped slide bar 11 will be affected by the contact force of the W-shaped rubber pad 17 with the steel plate and move upward. At this time, the fixed column 15 is guided by the inclined guide groove 14 when following the upward movement, which can make multiple L-shaped slide bars 11 expand outward at the same time. At this time, the L-shaped slide bar 11 will drive the slider 10 to expand outward laterally at the same time through the second slide sleeve 12. After contacting the steel plate, the W-shaped rubber pad 17 can firmly fix the processed steel plate when it expands outward synchronously, which enables the steel plate to obtain pulling force on both sides and be pressed downward at the same time.

[0040] Furthermore, by screwing the positioning nut 6, the position of the first sliding sleeve 8 can be adjusted left and right on the slide rail 7 to accommodate the fixing of steel plates of different sizes and shapes;

[0041] The multiple L-shaped slide rods 11 provided in the telescopic clamping assembly can expand and move separately, which enables bending when there are impurities or potholes on the surface of the steel plate, resulting in uneven thickness, and the area where the steel plate is fixed can also be effectively fixed.
