Description

Technical Field

[0001] The invention belongs to the technical field of forming mechanical equipment, in particular to a device for forming the camber of a steel beam bottom plate. Background Art

[0002] In the existing technology, the bottom plate of the curved steel beam is manually operated by padding something underneath to form the camber and fit it with the cover plate. This technology is not only inefficient and has low processing accuracy, but also has certain safety risks, and it is difficult to meet production needs. Summary of the invention

[0003] The purpose of the present invention is to overcome the deficiencies in the prior art and to provide a steel beam bottom plate camber forming device which can well control the camber accuracy, has high production safety and high production efficiency.

[0004] According to the technical solution provided by the present invention, the steel beam bottom plate camber forming device includes a base, a screw rod, a beam, a beam end seat, a moving block, a lifting cylinder, and a clamping block; screw rods are installed in the inner and outer bases, beam end seats are fixed at the inner and outer ends of the beam, the upper end of the screw rod is hinged to the beam end seat, inner and outer moving blocks are installed in each beam, a lifting cylinder is fixed on each moving block, a clamping block is fixed on the upper end of the piston rod of the lifting cylinder, the clamping part of the clamping block installed on the left moving block faces the right, and the clamping part of the clamping block installed on the right moving block faces the left, and a plurality of motors are fixed on the base, and each motor drives each of the screw rods.

[0005] Preferably, a dust cover is provided on the screw rod between the end seat of the beam and the base.

[0006] Preferably, a running rail is fixed inside the crossbeam.

[0007] Preferably, travel wheels are installed on the moving block.

[0008] The invention does not require workers to put things under the machine during operation. It only needs to adjust the lifting height of each group of vertical lifting mechanisms to form a certain height difference, and the bottom plate is bent by force to form a camber. The invention can also use digital control of the height difference, so the accuracy of the camber can be well controlled, and the production safety and production efficiency are high.

[0014] The present invention will be further described below in conjunction with specific embodiments.

[0015] The steel beam bottom plate camber forming device of the present invention is as follows: Figures 1 to 3 As shown, it includes a base 1, a screw rod 2, a cross beam 3, a cross beam end seat 4, a moving block 5, a lifting cylinder 6, and a clamping block 7; the screw rod 2 is installed in the inner and outer two parallel bases 1, and the screw rod 2 is installed in the corresponding base 1 at equidistant intervals, and the cross beam end seats 4 are fixed to the inner and outer ends of the cross beam 3, and the upper end of the screw rod 2 is hinged to the cross beam end seat 4, and the inner and outer moving blocks 5 are installed in each cross beam 3, and a lifting cylinder 6 is fixed on each moving block 5, and a clamping block 7 is fixed on the upper end of the piston rod of the lifting cylinder 6, the clamping part of the clamping block 7 installed on the left moving block 5 faces to the right, and the clamping part of the clamping block 7 installed on the right moving block 5 faces to the left, and a plurality of motors 8 are also fixed on the base 1, and each motor 8 drives each of the screw rods 2.

[0016] A dust cover 9 is provided on the screw rod 2 between the cross beam end seat 4 and the base 1 , and the dust cover 9 can prevent dust from adhering to the screw rod 2 and causing the screw rod 2 to run poorly.

[0017] A running rail 3.1 is fixed in the cross beam 3, and a running wheel 5.1 is installed on the moving block 5, and the running wheel 5.1 cooperates with the running rail 3.1.

[0018] When working, Figure 4 As shown, first, the bottom plate 10 to be formed into a camber is placed on the cross beam 3, and the moving blocks 5 on both sides are moved horizontally to be close to the bottom plate 10 through the walking wheels 5.1. Then, the lifting cylinder 6 drives the clamping block 7 to clamp the bottom plate 10. The upward extension length of each group of screw rods 2 is adjusted by the motor 8 to adjust the lifting height of the cross beam 3 to form a certain height difference, so that the bottom plate 10 forms the required curvature to meet the requirements of fitting with the cover plate.
