Description

Technical Field

[0001] The present invention relates to the technical field of reducing pipe processing, in particular to a reducing pipe processing device and a processing method for a spiral anchor. Background Art

[0002] Some spiral anchors are more than ten meters or even more than twenty meters long. In order to facilitate transportation and installation, they need to be assembled on site with multiple anchor rods. Figure 6 As shown, the existing anchor rod connection method is to weld the first anchor rod 23 and the connecting sleeve 25 together (first weld 26 and second weld 27). Then, the second anchor rod 24 is inserted into the connecting sleeve 25 on site and connected to the connecting sleeve 25 via a through-bolt. The disadvantages of this method are: welding the first weld 26 is difficult, and the weld quality and weld flaw detection cannot be verified. The through-bolt and outer sleeve increase the external dimensions of the anchor rod, and the anchor rod may cause soil loosening during construction. Figure 7 As shown, the connecting sleeve 25 is replaced with a reducer with only one weld. The reducer and the second anchor rod 24 are loosely matched and connected by through-pins, which can solve the above shortcomings. However, the processing of the reducer requires workers to hold one end of the reducer blank, place the end to be deformed in a heating furnace for heating, and then place the heated reducer blank in a deformation mold for deformation. After the processing is completed, the mold needs to be manually unloaded and the material needs to be unloaded, the processing efficiency is low, and workers are prone to injury. Summary of the Invention

The process does not require manual participation, thereby improving processing efficiency.

[0004] The technical solution of the present invention is implemented as follows: a reducer pipe processing device for spiral anchors includes a workbench, a heating station and a deforming station are provided on the workbench, a reciprocating positioning component is provided on the machine base between the heating station and the deforming station, the positioning component includes a vertically lifting positioning seat, a heating furnace is provided above the heating station, a machine base is provided at the deforming station, a vertically lifting deforming mold is provided on the machine base, the deforming mold is located above the positioning seat, a blanking component is fixed on the machine base between the deforming mold and the positioning seat, the blanking component includes two downwardly inclined blanking slides, a blanking chute is formed between the two blanking slides, the spacing of the blanking chutes is greater than the initial outer diameter d of the reducer blank, and smaller than the outer diameter D of the tapered end of the reducer after deformation, and a number of vertical stripping rods are also fixed on the machine base for stripping the reducer from the deforming mold.

[0005] Furthermore, the deformation mold includes a top plate, an annular side mold is provided at the lower end of the top plate, a conical mold is provided inside the annular side mold, the inner side of the annular side mold is an inclined surface, a V-shaped groove is formed between the annular side mold and the conical mold, and a coaxial positioning mold is provided at the lower end of the conical mold. The lower end of the stripper rod slides through the top plate and the conical mold in sequence. The provision of the stripper rod prevents the finished reducer from being embedded in the deformation mold.

[0006] Furthermore, each positioning seat includes a base plate, a positioning post is provided at the upper end of the base plate, a coaxial positioning ring plate is provided outside the positioning post, and a positioning groove is formed between the positioning ring plate and the positioning post.

The working end of the shifting and telescopic cylinder is connected to the lifting and telescopic cylinder, and the positioning seat is driven to reciprocate between the heating station and the deformation station through the shifting and telescopic cylinder.

[0008] A method for processing a reducer for a spiral anchor, using the processing device, comprises the following steps:

[0009] (1) The positioning seat is located at the heating station. The reducer tube blank is placed on the positioning seat. The positioning seat moves upward, driving the upper end of the reducer tube blank into the heating furnace for heating;

[0010] (2) After heating is completed, the positioning seat drives the reducer tube blank to move down and reset, and move to the deformation station; then the positioning seat drives the reducer tube blank to move up to the set height, and the upper end of the reducer tube passes through the blanking chute;

[0011] (3) The deformation die moves downward, so that the upper end of the reducer tube blank becomes a tapered end, and the reducer tube product is obtained. Then the deformation die moves upward and resets, and the stripping rod causes the reducer tube product to fall off the deformation die. After the positioning seat moves downward and resets to the heating station, the reducer tube product remains in the discharge chute and slides down the discharge chute to be discharged.

[0012] Beneficial effects of the present invention:

[0013] The present invention realizes the transfer of the diameter-reducing blank between the heating station and the deformation station through the reciprocating motion of the positioning component; through the cooperation of the vertically lifting deformation mold, the vertically lifting positioning seat, the stripping rod and the blanking component, the automatic deformation, stripping and blanking of the diameter-reducing pipe blank after heating are realized, and this process does not require human participation, thereby improving processing efficiency.

DETAILED DESCRIPTION

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without creative work are within the scope of protection of the present invention.

[0024] Example 1

[0025] like Figure 1As shown, a reducer pipe processing device for spiral anchors includes a workbench 1, on which a heating station 2 and a deforming station 3 are provided. A shift groove 4 is provided on a machine base 11 between the heating station 2 and the deforming station 3. A reciprocating positioning component is provided at the shift groove 4. The positioning component includes a vertically lifting positioning seat, and a vertical lifting and telescopic cylinder 5 is fixed to the lower end of the positioning seat. A shift telescopic cylinder 6 is also fixed to the machine base 11. The working end of the shift telescopic cylinder 6 is connected to the cylinder body of the lifting and telescopic cylinder 5. The positioning seat is driven to move along the moving groove by the shift telescopic cylinder 6, thereby performing reciprocating motion between the heating station 2 and the deforming station 3.

[0026] like Figure 1 、 2 As shown in FIG4 , the positioning seats include a base plate 7, a positioning column 8 is fixed to the upper end of the base plate 7, a coaxial positioning ring plate 9 is fixed to the outer side of the positioning column 8, and a positioning groove is formed between the positioning ring plate 9 and the positioning column 8. The lower end of the reducer blank 21 is placed in the positioning groove, and the positioning column 8 is placed in the reducer blank 21. The reducer is positioned and fixed by the cooperation of the positioning column 8 and the positioning ring plate 9.

[0027] like Figure 1 As shown, a heating furnace 10 is fixed above the heating station 2 via a bracket. The upper end of the reducer tube 21 is the deformation end. The upper end of the reducer tube 21 is driven into the heating furnace 10 for heating by the vertical lifting of the positioning base, facilitating subsequent deformation. A vertical machine base 11 is fixed to the deformation station 3, and a vertical lifting and telescopic cylinder 12 is fixed to the machine base 11. The deformation mold is fixed to the lower end of the lifting and telescopic cylinder 12, and the deformation mold is driven to move vertically by the lifting and telescopic cylinder 12. The deformation mold includes a top plate 13, a ring-shaped side mold 14 is fixed at the lower end of the top plate 13, a coaxial tapered mold 15 is fixed on the top plate 13 inside the ring-shaped side mold 14, the inner side of the ring-shaped side mold 14 is an inclined surface, and a V-shaped groove is formed between the ring-shaped side mold 14 and the tapered mold 15. The V-shaped groove is used for forming the welding bevel of the reducer, and no additional processing of the bevel is required subsequently. A coaxial positioning mold 16 is provided at the lower end of the tapered mold 15. The tapered mold 15 and the positioning mold 16 are an integrated structure. The positioning mold 16 is placed in the reducer blank 21, and the tapered mold 15 is used for forming the tapered end of the reducer.

[0028] A plurality of vertical stripper rods 17 are also fixed to the machine base 11. The stripper rods 17 are arranged along the circumference of the deformation mold. The lower ends of the stripper rods 17 slide through the top plate 13 and the tapered mold 15 in sequence. The deformation mold moves downward along the stripper rods 17, which serve as a guide. After the deformation mold moves upward and resets, it extends from the tapered mold 15 through the stripper rods 17. If the finished reducer tube 22 is embedded in the tapered mold 15, the stripper rods 17 can be used to strip the finished reducer tube 22 from the deformation mold, preventing the finished reducer tube 22 from moving upward synchronously with the deformation mold.

[0029] like Figure 1 and 3 As shown, the deformation mold is located above the positioning seat. A blanking assembly 18 is fixed on the machine base 11 between the deformation mold and the positioning seat. The blanking assembly 18 includes two downwardly inclined blanking slides 19. The end of the blanking slide 19 close to the heating station 2 is the upper end, and the other end is downward. A blanking chute 20 is formed between the two blanking slides 19. The spacing of the blanking chute 20 is greater than the initial outer diameter d of the reducer blank 21 and smaller than the outer diameter D of the tapered end of the reducer after deformation. Figure 4 As shown, the initial state of the reducer tube blank 21 is a constant diameter tube, and its initial outer diameter is d. Figure 5 As shown, the upper end of the reduced tube product 22 is tapered, and the outer diameter of the tapered end increases, that is, the outer diameter D of the tapered end is larger than the initial outer diameter d of the reduced tube body 21. The spacing of the discharge chutes 20 is larger than the initial outer diameter d of the reduced tube body 21, and smaller than the outer diameter D of the tapered end after deformation. This spacing of the discharge chutes 20 facilitates the upper end of the reduced tube body 21 to pass through the discharge chutes 20. After subsequent processing is completed, it also facilitates the reduced tube product 22 to remain in the discharge chutes 20 and slide out along the discharge chutes 20.

[0030] Example 2

[0031] Using the processing device described in Example 1, a method for processing a reducer for a spiral anchor includes the following steps:

[0032] (1) The shift telescopic cylinder 6 contracts, driving the positioning seat to be located at the heating station 2, and placing the reducer tube blank 21 on the positioning seat; the lifting telescopic cylinder 5 extends, driving the positioning seat to move upward, and driving the upper end of the reducer tube blank 21 into the heating furnace 10 for heating;

[0033] (2) After heating is completed, the lifting telescopic cylinder 5 contracts, the positioning seat drives the reducer tube body 21 to move down and reset, the shifting telescopic cylinder 6 extends, the positioning seat drives the reducer tube body 21 to move to the deformation station 3; then the lifting telescopic cylinder 5 extends, the positioning seat drives the reducer tube body 21 to move up to the set height, and the upper end of the reducer tube passes through the unloading chute 20;

[0034] (3) The lifting and telescopic cylinder 12 extends, driving the deformation mold to move downward, the positioning mold 16 extends into the reducer, the tapered mold 15 makes the upper end of the reducer blank 21 become a tapered end, and the annular side mold 14 forms the welding bevel of the reducer. Then the lifting and telescopic cylinder 12 contracts, the deformation mold moves up and resets, and the stripping rod 17 makes the reducer finished product 22 fall off the deformation mold; the jacking and telescopic cylinder 5 contracts, and after the positioning seat moves downward, the shifting and telescopic cylinder 6 contracts and drives the positioning seat back to the heating station 2. The reducer finished product 22 remains in the unloading chute 20 and slides out along the unloading chute 20.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
