Description
Technical Field
[0001] The utility model relates to the technical field of steel plate bending processing equipment, in particular to an upper crossbeam for a bending machine. Background Art
[0002] The manufacturing process of welded steel pipes in the prior art usually involves bending and curling a steel plate into a cylindrical shape and then welding the two edges of the steel plate to obtain a steel pipe. The steel plate bending or curling process usually uses a bending machine to repeatedly press and bend the steel plate to bend the steel plate into a tubular shape. First, a bending machine is used to bend one half of the steel plate to form a C-shaped structure, and then the other half of the steel plate is bent by the bending machine to form another C-shaped structure. The two C-shaped structures are arranged opposite to each other to form a cylindrical workpiece with an opening. After the cylindrical workpiece is removed from the bending machine, the opening is manually spot welded and butt welded to form a complete steel pipe.
[0003] In the existing process of applying pressure to bend the steel plate by a bending machine, multiple cylinders installed on the upper beam drive the same pressure head to move downward. In this process, since the pressure head is driven by the cylinder, its movement path is easily affected by the cylinder. When the cylinder applies uneven force or the pressure is insufficient, it is easy to cause the pressure head to deviate, resulting in different position intervals or pressures on the steel plate, affecting the bending angle of the steel plate, and then affecting the bending accuracy of the steel plate, requiring manual rework and adjustment, reducing production efficiency.

[0029] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0030] like Figures 1 to 3 As shown together, the utility model comprises two oppositely arranged side plates 1, and two end plates 2 are fixedly arranged between the two side plates 1. The two side plates 1 and the two end plates 2 together surround and form a complete accommodating area, and the accommodating area is used to accommodate the oil cylinder.
[0031] The utility model also includes a clamping guide device 3; the clamping guide device 3 includes a guide mounting seat 31 fixedly arranged at the bottom of the side plate 1, two guide mounting plates 32 arranged oppositely are fixedly arranged on the guide mounting seat 31, and a guide mounting plate inclined surface 321 is arranged on the guide mounting plate 32, and at least one adjustment plate 33 is adjustably installed on the guide mounting plate 32, and the two adjustment plates 33 arranged on the two guide mounting plates 32 are arranged oppositely, and the adjustment plate 33 is provided with an adjustment plate inclined surface 331 adapted to the guide mounting plate inclined surface 321.
[0032] When the adjusting plate inclined surface 331 slides along the guiding mounting plate inclined surface 321, one adjusting plate 33 approaches or moves away from the other adjusting plate 33, or the two adjusting plates 33 approach or move away from each other, the pressing head between the two adjusting plates 33 can be clamped and guided, and the pressing head can only move between the two adjusting plates 33, thereby limiting the moving direction of the pressing head and preventing the pressing head from deviating. Moreover, by adjusting the positions of the two adjusting plates 33, the downward movement path of the pressing head can be fine-tuned, thereby improving the bending accuracy of the bending machine, improving production efficiency, and reducing production costs.
[0033] In the present invention, copper plates 34 are installed on the opposite surfaces of the two adjustment plates 33 , and the copper plates 34 abut against the pressure head, which can prevent the pressure head and the adjustment plates 33 from directly rubbing against each other, thereby increasing the service life of the pressure head and the adjustment plates 33 .
[0034] The copper plate 34 is provided with a lubrication groove 341, and the adjustment plate 33 is provided with an oil injection hole 332. The lubrication groove 341 is connected with the oil injection hole 332, and the oil injection hole 332 is connected with the outside through an oil passage provided in the adjustment plate 33. In the process of clamping and guiding the pressure head, the copper plate 34 and the adjustment plate 33 will not move relative to each other. Therefore, the positions of the oil injection hole 332 and the lubrication groove 341 will not change relative to each other. The lubrication oil from the outside can enter the lubrication groove 341 through the oil passage and the oil injection hole 332, and lubricate the pressure head abutting against the copper plate 34, thereby reducing the friction between the pressure head and the copper plate 34 when the pressure head moves, reducing the movement resistance, and improving the movement effect.
[0035] The guide mounting plate 32 is provided with a guide mounting groove 322, the guide mounting plate inclined surface 321 is arranged at the groove bottom of the guide mounting groove 322, the adjustment plate 33 is clamped in the guide mounting groove 322, and the guide mounting groove 322 limits the adjustment plate 33 to move with the pressure head, thereby improving the adjustment effect.
[0036] like Figure 1 , Figure 4 , Figure 5 As shown together, a bottom plate 4 is fixed between the two side plates 1, and a plurality of cylinder mounting holes 5 are opened on the bottom plate 4 along its length direction. After the cylinder is installed in the accommodation area, the driving end of the cylinder extends downward through the cylinder mounting hole 5 and is fixedly connected to the pressure head, so as to drive the pressure head to move back and forth in the vertical direction. Among them, the cylinder mounting hole 5 includes a pressing cylinder mounting hole 51 and a lifting cylinder mounting hole 52. The pressing cylinder mounting hole 51 is used to install the pressing cylinder, and the lifting cylinder mounting hole 52 is used to install the lifting cylinder.
[0037] A plurality of ribs 6 are fixedly arranged between the two side plates 1, and the ribs 6 are fixedly connected to the bottom plate 4. The arrangement of the ribs 6 can enhance the connection strength between the two side plates 1 and the bottom plate 4. At the same time, the ribs 6 are arranged close to the cylinder mounting holes 5 to improve the connection strength at the cylinder mounting location.
[0038] When the utility model is in use, the adjustment plate 33 slides along the guide mounting plate inclined surface 321 through the cooperation between the adjustment plate inclined surface 331 and the guide mounting plate inclined surface 321, and the position of the adjustment plate 33 on the guide mounting plate 32 is adjusted. The two relatively arranged adjustment plates 33 cooperate with each other, and the clamped pressure head can only move between the two clamping guide devices 3, thereby changing the degree of deviation of the pressure head in the vertical direction, and fine-tuning the moving path of the pressure head to prevent the pressure head from deviating, thereby ensuring that the position interval of the pressure head pressing on the steel plate is the same, and ensuring the bending accuracy of the steel plate, thereby improving production efficiency and reducing production costs.
[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
