Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of metal profile processing equipment, in particular to an automatic punching equipment for steel frame. BACKGROUND

[0002] In a solar power station, a metal profile frame structure is often used as a support frame. In profile processing, a steel plate is rolled into a steel frame profile after entering a rolling line, and then a corresponding hole opening equipment is used to reserve mounting holes and grounding hole positions on the steel frame.

[0003] The existing hole opening equipment, such as Chinese patent CN105562511A, is named "profile automatic punching machine". The patent includes a rack, a clamping device, a punching die, a crossbeam, an automatic limiting device, a driving device, a mechanical limiting device, and a controller. The crossbeam is provided with an automatic limiting device and a mechanical limiting device, which are respectively used to realize the automatic positioning function and the mechanical positioning function of the crossbeam.

[0004] Since the hole diameter parameters and positions of the mounting holes and grounding hole positions on the steel frame profile are different, in order to improve the processing efficiency, the existing technology adopts the mode of using multiple groups of punches with different dies to punch a section of steel frame profile at the same time, so as to reserve mounting holes and grounding hole positions on the steel frame at the same time. However, this mode has the following disadvantages. In actual production, since the length dimensions of long frames and short frames required by each customer are the same, only the spacing between grounding holes and mounting holes is different, and the delivery cycle of the order is relatively short. For example, after the production of customer A product is completed, the spacing between the new grounding hole and the mounting hole die needs to be adjusted to produce the product of customer B. However, the hole spacing adjustment of the existing punching equipment is difficult. Multiple fastening screws between the punching equipment and the base need to be disassembled and assembled each time, so that the flexible adaptability of hole spacing adjustment is poor, and the punching equipment has a high occupancy rate for single model size product.

[0043] Further, the limiting groove 3.244 is composed of multiple blind holes, the tooth groove 3.242 comprises an arc-shaped groove 3.2421 located at the bottom of the sliding block 3.241, an arc-shaped rack 3.2422 fixed to the arc-shaped groove bottom of the arc-shaped groove 3.2421 is capable of being clamped with the worm roller 3.23, when the arc-shaped rack 3.2422 is separated from the worm roller 3.23, at this time the sliding block 3.241 is in the avoiding position, the pin shaft hole 11 is provided on one side of the gear space 10 opened on the groove wall of the arc-shaped groove 3.2421, the pin shaft hole 11 is movably connected with the pin shaft 12, the long limiting groove 22 is arranged on the inner wall surface of the pin shaft hole 11, the sliding sheet 23 fixed with the pin shaft 12 is slidably connected in the long limiting groove 22, the length direction of the long limiting groove 13 is parallel to the length direction of the pin shaft 12, the number of the long limiting groove 13 is not less than 2, preferably, the number of the long limiting groove 13 is three, so as to limit the axial rotation of the pin shaft 12, the outer end of the pin shaft 12 capable of extending outwards and being inserted into the limiting groove 3.244 is the outer end of the pin shaft 12, the sleeve 13 is movably connected to the outer end of the pin shaft 12, the sleeve 13 is connected with the outer end of the pin shaft 12 through the spring 14, the sleeve 13 is capable of being inserted into the limiting groove 3.244, the bottom outer end of the sleeve 13 is a semicircular sphere, which is used to reduce the rotating friction, the other end of the pin shaft 12 is screwedly connected with the threaded sleeve 15, the other end of the threaded sleeve 15 is fixedly connected with the internal gear 16, the internal gear 16 is rotatably arranged in the gear space 10, the gear teeth of the internal gear 16 are engaged with the worm roller 3.23, preferably, the worm roller 3.23 and the straight tooth cylinder are of the same structure, the moving direction of the internal gear 16 is in the tooth line direction of the worm roller 3.23;

[0044] In actual use, when the sliding block 3.241 is in the blocking position, at this time the gear teeth of the internal gear 16 are engaged with the worm roller 3.23, since the worm roller 3.23 is limited by the arc-shaped rack 3.2422, at this time the internal gear 16 does not rotate; when the sliding block 3.241 is in the avoiding position, at this time the gear teeth of the internal gear 16 are still engaged with the worm roller 3.23, since the worm roller 3.23 is separated from the limitation of the arc-shaped rack 3.2422, when the worm 4.1 continues to rotate, at this time the worm roller 3.23 can rotate, so that the internal gear 16 engaged with the worm roller 3.23 rotates synchronously, in the rotating process of the internal gear 16, at this time the rotation of the threaded sleeve 15 makes the pin shaft 12 extend outward until being inserted into the corresponding limiting groove 3.244, so as to limit the sliding block 3.21;

[0049] Further, the extension rod 17 is spirally inserted into the sleeve 6.21, and the extension rod 17 is provided with scale marks, in actual use, when the distance between the punching devices 2 needs to be controlled, the extension length of the extension rod 17 is adjusted, when the two punching devices 2 reach the preset distance, the extension rod 17 receives axial extrusion force, so that the sleeve 6.21 is axially moved in time in the through cavity 6.1, so that the corresponding sliding block 3.21 no longer receives the driving of the worm 4.1, and under the continuous rotation of the worm 4.1, the sliding block 3.21 is limited in the through slot 3.12 through the pin 12, that is, in the distance adjustment process between the punching devices 2, when the punching devices 2 reach the specified distance, the driving force of the worm 4.1 is no longer received to move, and the driving force of the worm 4.1 is used to lock in the stopped position, which is beneficial to improve the adjustment efficiency.
