AI Technical Summary
When adjusting the position of the steel connection holes before the photovoltaic bracket is formed, the existing multi-station hydraulic press needs to disassemble and reinstall the oil cylinder, which is time-consuming and labor-intensive and leads to low production efficiency.
A gravity center adjustable punching machine is designed. By providing parallel grooves and longitudinal projections on the top of the cylinder, combined with the structure of the longitudinal rod, the cross rod and the limit pressure rod, the oil cylinder allows sliding along the cross rod to adjust its position and pass through Bolted to avoid disassembly and install.
This greatly improves production efficiency, reduces operating time and labor intensity, and achieves fast and accurate hole position adjustment.

[0002] It is well known in the photovoltaic bracket production and application industry that before the photovoltaic bracket is formed, it is necessary to process the through holes for connection. At present, the equipment used to process the connection holes of the steel section before the photovoltaic bracket is formed is a multi-station hydraulic punching machine. This multi-station hydraulic punching machine contains a machine base frame, which is a rectangular frame, on which a bottom plate is connected, and above the bottom plate there is a top frame with the same contour as the bottom plate. The bottom plate and the top frame are both rectangular and equal in area, and columns are connected between their four corners. There are no less than two oil cylinders longitudinally below the top frame, and the oil cylinder contains a cylinder body and a piston rod, and the outer end of the piston rod is downward and connected to a pressure plate. Among them, the cylinder body of the oil cylinder is fixedly connected to the top frame. When it is necessary to adjust the front and rear position dimensions of the connection holes on the steel section, the oil cylinders need to be removed from the top frame one by one, and after adjusting the front and rear position dimensions of the connection holes on the steel section, they need to be installed on the top frame one by one, which is not only time-consuming and labor-intensive, but also has low production efficiency. Utility Model Content
[0003] The problem to be solved by the utility model is to overcome the above-mentioned shortcomings and provide a gravity center adjustable punching machine for punching steel workpieces. The utility model can not only save time and labor, but also greatly improve production efficiency.
[0004] The above-mentioned problems to be solved by the utility model are achieved by the following technical solutions:
[0005] The utility model discloses a gravity center adjustable punching machine for punching steel workpieces, comprising a base frame, which is a rectangular parallelepiped frame, on which a bottom plate is connected, and a top plate is arranged above the bottom plate. The bottom plate and the top plate are both rectangular and of equal area, and columns are connected between their four corners. The top plate is evenly distributed with screw holes, and there are no less than two oil cylinders in the longitudinal direction below it, which contain a cylinder body and a piston rod, and the outer end of the piston rod faces downward and is connected to a pressure plate. It is characterized in that: a pair of opposite cylinder wall outer sides at the top of the cylinder body are provided with grooves, and the two grooves are parallel. The top plates on both sides of the cylinder body are connected with cross bars, and the side of the cross bars adjacent to the grooves is provided with longitudinal protrusions, and the longitudinal protrusions are slidably inserted into the corresponding grooves. Another pair of opposite cylinder wall outer sides at the top of the cylinder body are connected with longitudinal rods, and the two longitudinal rods are parallel to each other and to the longitudinal direction of the top plate. The outer sides of the cross bars between the two ends of the longitudinal bars are provided with limit pressure rods, the inner ends of the limit pressure rods are pressed under the corresponding cross bars, and the other ends are connected with the bottom of the top plate.
[0006] A further improvement of the utility model is that an anti-drop rod is connected between the same ends of the two cross bars.
[0007] A further improvement of the utility model is that the long sides of the bottom plate and the top plate are evenly distributed with rod holes, and there are tie rods between the corresponding rod holes. The upper end and the lower end of the tie rod are respectively passed through the corresponding rod holes on the top plate and the corresponding rod holes on the bottom plate, and nuts are screwed on their passing ends.
[0008] A further improvement of the utility model is that a gasket is provided on the protruding end between the nut and the bottom plate or the top plate.
[0009] It can be seen from the above scheme that since there are grooves on the outer side of a pair of relative cylinder walls at the top of the cylinder body, the two grooves are parallel. The top plates on both sides of the cylinder body are connected with cross bars, and the side of the cross bars adjacent to the grooves has longitudinal protrusions, and the longitudinal protrusions are slidably inserted into the corresponding grooves. The other pair of relative cylinder wall outer sides at the top of the cylinder body are connected with longitudinal bars, and the two longitudinal bars are parallel to the longitudinal direction of the top plate. There are limit pressure rods on the outer side of the cross bars between the two ends of the longitudinal bars, and the inner end of the limit pressure rod is pressed under the corresponding cross bar, and the other end is connected to the bottom of the top plate. When it is necessary to adjust the front and rear position size of the connection hole on the steel section, it is only necessary to loosen the bolts between the longitudinal bar, the cross bar, the limit pressure rod and the top plate, push the cylinder body of the oil cylinder to move horizontally along the two cross bars to the desired position, and then use bolts to fix the longitudinal bar, the cross bar, the limit pressure rod and the top plate together. Compared with the background technology, there is no need to remove the oil cylinders from the top frame one by one, adjust the front and rear position sizes of the connecting holes on the steel section, and then install them on the top frame one by one, which not only saves time and labor, but also greatly improves production efficiency.
