Description

Technical Field

[0001] The utility model belongs to the technical field of ground pile production equipment, and in particular relates to a ground pile tip shrinking production line for continuous production of ground piles. Background Art

[0002] Ground piles are a type of rivet commonly used in the fields of electricity and construction. Their overall structure is cylindrical with sharp corners at the ends. In order to facilitate plugging into the ground, spiral blades are usually provided on the outer diameter of the ground piles.

[0003] When producing the above-disclosed ground pile workpiece, the process is to cut the steel pipe, put the steel pipe into the heating device manually, heat the steel pipe, and then move the steel pipe to the tube shrinking machine manually. The sharp corners are formed by the tube shrinking machine, and the formed ground pile is placed on the round hole processing equipment again for round hole processing. During the processing, all semi-automatic auxiliary processing is required to be carried out by manual labor and positioned. The disadvantages of this processing method are: 1. Low efficiency, frequent personnel participation is required in the whole process. Because the weight of the ground pile is more than 3 kilograms, thousands of ground piles are continuously processed during batch processing, which brings great pressure to the production operators; 2. The operation risk factor is high. During the processing operation, the heating, tube shrinking and drilling of the ground pile all need to be completed by equipment, and there is also a high temperature environment during the processing, which poses a great safety hazard to the personnel working between the equipment; 3. The processing accuracy is low. The existing processing method is frequently disturbed by the operator. If the operator does not operate properly during the movement and positioning of the ground pile, it is easy to cause the product accuracy to be unable to be guaranteed.

[0004] In response to the above technical problems, as technical personnel in this industry, the technical problem that urgently needs to be solved is: it is urgent to design and develop a spiral ground pile welding machine that can realize automatic operation, can realize continuous processing of ground piles through automatic connection between multiple devices, and can effectively guarantee the processing accuracy during the processing process. This is a technical problem that technical personnel in this field urgently need to solve. Utility Model Content

[0030] As shown in the attached drawings, a pile tip shrinking production line includes an inclined feeding rack 1, which is arranged toward a vertical lifting rack 4. The inclined feeding rack 1 is a common equipment in the field of mechanical material transportation and will not be described in detail here.

[0031] A vertical lifting frame 4 is provided at the lower end of the inclined feeding frame 4, and a work station support frame 2 is provided on the rear side of the vertical lifting frame 4. A plurality of supporting stations are provided on the work station support frame, which are, from the vertical lifting frame 4 to the outside, an internal temporary storage station 25, a heating station 24, a tube shrinking station 23, a punching station 22, and an external temporary storage station 21.

Through the above structural arrangement, under the drive of the heating drive cylinder 61, the electric heating coil 65 can be dragged in and out of the ground pile end around the ground pile, and when the electric heating coil 65 is arranged around the ground pile, high-temperature heating of the end can be achieved.

[0035] The tube shrinking module 7 is a fixed type, which includes a tube shrinking machine 71, on which a tube shrinking machine head 72 is arranged, and a tube shrinking die 74 is arranged on the rotating machine head 72 facing the tube shrinking station 23 support frame, and the tube shrinking die 74 is clamped and driven by the vertical tube shrinking drive cylinder 73 on the rotating machine head 72.

[0038] When the utility model is working, the ground pile slides to the right side of the internal temporary storage station 25 through the inclined feeding rack 1 and is blocked. The vertical lifting rack 4 drives the pallet 44 to lift the ground pile on the upper part of the pallet 44 to the upper part of the internal temporary storage station 25, and the ground pile automatically rolls into the internal temporary storage station 25. In this process, the ground pile is blocked from sliding down to the bottom of the pallet 44 by multiple blocking parts 43.

[0039] Next, the stepping material transfer machine 5 is operated to move the ground pile in the internal temporary storage station 25 to the heating station 24. At this time, the electric heating coil 65 can be dragged around the ground pile by driving the heating drive cylinder 61 on the heating module 6. When the electric heating coil 65 is arranged around the ground pile, high-temperature heating of the end can be achieved. After heating is completed, the heating drive cylinder 61 on the heating module 6 applies force in the reverse direction to drag the electric heating coil 65 away from the end of the ground pile.

[0040] Next, the stepper material transfer machine 5 is operated to shift the ground pile in the heating station 24 to the tube shrinking station 23.

Then, the vertical drive cylinder 35 drives the movable clamping end 36 to cooperate with the clamping bottom mold 37 to clamp the ground pile toward the tube shrinking module 7 to achieve sharp-angle tube shrinking processing.

[0041] Next, the stepper material transfer machine 5 is operated to move the ground pile in the tube shrinking station 23 to the drilling station 22. At this time, the drilling drive cylinder 81 on the drilling module 8 drives the vertical frame 84 to move toward the ground pile. The vertical frame 84 is provided with a drilling gun 85. The front end of the bottom plate 83 is provided with a pusher 86, which is arranged at the lower part of the ground pile corner. When drilling, the driving stroke of the drilling drive cylinder 81 is set. When the vertical frame 84 moves, as shown in FIG. Figure 7 As shown, the pushing portion 86 at the front end of the bottom plate 83 pushes the ground pile to move. When the pushing portion 86 contacts the sharp corner of the ground pile, it is pushed for a distance. At this time, the ground pile is already stable in the drilling station 22. After the bottom plate 83 stops moving, a hole is drilled on the sharp corner by the drilling gun 85.

[0042] Next, the stepping material transfer machine 5 is operated to move the ground piles in the drilling station 22 to the external temporary storage station 21. At this time, the external equipment is waited for to move the ground piles.

[0043] Through the above structure and operation mode, the utility model can realize inclined material guiding by the deadweight of the ground pile through the inclined feeding frame 1, and then gradually shift and process between the heating module 6, the shrinking module 7 and the punching module 8 through the stepping material moving machine 5. The device has a novel structure design and is easy to operate. It can effectively process the ground pile step by step, and the whole process is automatic, which improves efficiency and accuracy and has a higher safety factor.
