Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of high-strength alloy template punching, and particularly relates to alloy U plate multi-group punching equipment. BACKGROUND

[0002] At present, in the construction field and the construction process of high-speed railway bridges, high-strength alloy U plates and scaffolds are gradually used to replace wooden templates and aluminum template scaffolds. The aluminum template is expensive (about 600 yuan per square meter), and the aluminum alloy is prone to sticking to dust, and the phenomenon of wave lines and drumming occurs. The use of high-strength alloy U plates greatly reduces the use of wood and reduces resource waste. The high-strength alloy U plate (about 220 yuan per square meter) can be repeatedly used and recycled, and the high-strength alloy U plate is flexible and fast in assembly, has high size matching degree, and greatly improves the construction speed and construction quality.

[0003] The material of the high-strength alloy U plate is S550GD galvanized aluminum magnesium, and the strength and rigidity of the same square aluminum template are similar. The reaction degree of the high-strength steel template with concrete is weaker than that of the aluminum alloy, and the high-strength alloy U plate is not prone to sticking to dust and can be directly washed with a high-pressure water gun. The high-strength alloy U plate is formed by laser welding, and the width is 100-400 mm in multiple specifications. The alloy U plate is the most important component, and punching is often completed on one side, and then manually adjusted to punch the other side. The web punching is completed on another mechanical device, and a trolley is required. After multiple operations, the punching precision and the distance between holes are difficult to guarantee. Manual type adjustment is required for multiple type changes, and the first two pieces need to be measured and then the type adjustment mold is adjusted after type change. Unqualified products may be produced due to unsuitable type adjustment, and finally batch production is required.

[0004] In summary, how to provide alloy U plate multi-group punching equipment can solve many problems in the production and use of high-strength alloy U plates. One device can complete automatic feeding, clamping, bidirectional multi-row punching, and multi-row web punching at the same time, and can also reduce costs and reduce the operation difficulty of workers.

4. The multi-group punching equipment for alloy U-plates as described in claim 3, characterized in that, The feeding mechanism includes an L-shaped connecting plate. A second servo motor, a second reducer, a gear, and a first cylinder are mounted on the horizontal surface of the L-shaped connecting plate. A third linear guide slider assembly is mounted on the vertical plane of the L-shaped connecting plate. A moving plate and an automatic clamping mechanism are mounted on the third linear guide slider assembly. The second servo motor drive shaft is connected to the second reducer, which is connected to the gear. The gear meshes with the rack for transmission. The first cylinder drives the moving plate to move up and down along the third linear guide slider assembly. The lower part of the first cylinder is connected to the automatic clamping mechanism, driving the automatic clamping mechanism to move up and down.

5. The multi-group punching equipment for alloy U-plates as described in claim 4, characterized in that, The automatic clamping mechanism includes a second cylinder, a connecting rod, an upper clamping head, a lower clamping head, and a mounting frame. The second cylinder is installed inside the mounting frame. The second cylinder is connected to one end of the upper clamping head through the connecting rod. The middle part of the upper clamping head is hinged to the mounting frame. The other end of the upper clamping head works together with the lower clamping head to clamp the alloy U-plate.

6. The multi-group punching equipment for alloy U-plates as described in claim 1, characterized in that, The web punching mechanism includes multiple punching devices distributed along the length of the web. A fourth linear guide slider pair is provided on the second punching base. The fourth linear guide slider pair is along the X-axis. Multiple base plates are installed on the fourth linear guide slider pair. A fixed seat is installed on each base plate. A lead screw is provided on the fixed seat along the Y-axis. The lead screw is connected to the punching device through a connecting seat.

7. The alloy U-plate multi-group punching equipment as described in claim 1, characterized in that, The first guide assembly includes two rows of guide assemblies arranged opposite each other; each row of guide assemblies includes several guide units arranged in sequence, and each guide unit includes a mounting plate, a guide transmission wheel, a clamping cylinder and a guide plate. Two guide transmission wheels and a clamping cylinder are fixed on the mounting plate, and the guide plate is located at the bottom of the mounting plate. Several drill bit guide holes are provided on the guide plate.
