Description

Technical Field

[0001] This utility model relates to the technical field of square pile end plate processing equipment, specifically a punching device for a punch press used for processing square pile end plates. Background Technology

[0002] The square pile end plate is a component installed at both ends of a prestressed concrete hollow square pile. It is mainly used for anchoring the prestressed tension steel bars during the production of square piles and for splicing piles during construction. When processing the square pile end plate, it is necessary to punch holes in the square pile end plate to facilitate the subsequent quick docking and installation of the square pile end plate.

[0003] For example, the utility model patent disclosed in publication number CN215965777U discloses a punching mechanism for a punch press used for processing square pile end plates. The mechanism includes a main body and a positioning block. An operating groove is provided inside the main body, and a motor is installed inside the operating groove. The output end of the motor is connected to a first gear. A bearing is installed inside the operating groove, and a first rotating rod is connected through the bearing. This punching mechanism of the punch press for processing square pile end plates is equipped with a cylinder that can slide along a threaded ring. When the threaded ring slides along the thread, it can drive a notch to rotate. When the notch rotates to the side of another set of notches, it can engage with the positioning block. After the notch engages with the positioning block, it pulls the punching block, which can move a fixed block. When the fixed block moves, it can slide through a fixed groove, and when the fixed block slides, it can drive the positioning block to move. When the positioning block moves, it can slide and separate through a notch, facilitating the disassembly and replacement of the punching block.

[0004] Although the above-mentioned equipment can perform punching operations on the end plates of square piles, its efficiency in cyclic punching of the end plates of square piles is still insufficient, which reduces the processing speed of the end plates of square piles. Therefore, there is an urgent need for a punching device for a punch press for processing the end plates of square piles to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide a punching device for a punch press used for processing square pile end plates, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a punching device for a punch press used for processing square pile end plates, comprising a support base, aluminum profile columns at the four corners of the upper end face of the support base, and a support top plate at the upper end face of the four sets of aluminum profile columns; and four sets of support brackets equidistantly arranged near the interior of the upper end face of the support base.

[0007] A guiding device is fixedly installed at the middle of the inner end face of the support base, and a stepper motor is provided at the input end of the guiding device. The guiding device is used for positioning and guiding.

[0008] A punching device is fixedly installed on the inner end face of the support top plate near the front part, and the punching device is used for punching and limiting.

[0009] Preferably, the punching device includes a thin cylinder, the output end of which is provided with a cylinder guide rod, and a guide slide is fixedly provided at the center of the lower end face of the cylinder guide rod. Two sets of guide slide shafts are provided on the upper end face of the guide slide, and four sets of punching dies are equidistantly provided on the lower end face of the guide slide.

[0010] Preferably, the guiding device includes a hollow rotating platform, a guide turntable is fixedly installed at the center of the upper end face of the hollow rotating platform, and four sets of positioning fixtures are fixedly engaged at equal intervals on the inner end face of the guide turntable. A limit clamping shaft is fixedly installed at the center of the inner end face of the positioning fixture, and four sets of alignment guide grooves are opened at equal intervals on the inner end face of the positioning fixture. Four sets of square pile end plates are slidably engaged at equal intervals on the inner end face of the guide turntable.

[0011] Preferably, the guide slide is slidably engaged with the inner end face of the support top plate via the guide slide shaft, and the guide slide and the limiting shaft are coaxial and directly opposite each other, which can effectively improve the stability of the subsequent displacement of the guide slide in the output direction of the cylinder guide rod, and also improve the stability and accuracy of the equipment in punching the square pile end plate.

[0012] Preferably, the square pile end plate is slidably engaged with the upper end face of the positioning fixture via the limiting clip shaft. The limiting clip shaft can slide and limit the middle part of the square pile end plate, thereby limiting the radial direction of the square pile end plate and improving the stability of the radial limit when punching the square pile end plate.

[0013] Preferably, the four sets of alignment guide grooves are directly opposite the four sets of punching dies. When punching the end plate of the square pile, the alignment guide grooves can provide sufficient guiding space for the punching die, thereby improving the punching stability of the punching die.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model, by setting up a punching device and a guiding device, enables the stepper motor to drive the guide turntable to rotate intermittently by 90 degrees through the hollow rotating platform during the cyclic feeding and punching of the square pile end plate. This allows the guide turntable to drive the square pile end plate to be cyclically positioned at the bottom of the guide slide through the positioning fixture, effectively improving the efficiency of the equipment in cyclic feeding of the square pile end plate. At the same time, the thin cylinder can cooperate with the rotation of the guide turntable to guide the material, performing uninterrupted punching of the square pile end plate, thereby improving the efficiency of the equipment in punching the square pile end plate.
