And then, gradually applying the stress of gradually increasing the stroke by matching the displacement of the grouting pipe section with the three pressing hammers so as to enable the three triangular plates to bend out of radian, and thus, the head structure of the grouting pipe is manufactured. The processing efficiency is greatly improved, the labor cost is reduced, and the process difference in the original manual operation process can be reduced through mechanical accurate cutting and forming, so that the product quality is improved.

The geological exploration steel pipe processing method improves the structure of the cutting seam, and the three triangle structures can be left on the grouting pipe section except that the traditional cutting seam is formed by connecting three first inclined cutting seams and three second inclined cutting seams in an end-to-end mode at intervals. When the joint of the first inclined cutting slot and the second inclined cutting slot is cut, the static steel pipe blank of the cutting torch rotates clockwise and anticlockwise alternately, and a horizontal cutting slot structure is additionally arranged, so that the joint of the triangular plate and the grouting pipe section is reduced. Therefore, when the triangle is bent to form, the connection point of the triangle and the grouting pipe section cannot be greatly deformed to influence the quality of a finished product as in the traditional processing mode.
3. According to the geological exploration steel pipe processing method, when the horizontal cutting seam is cut, when the cutting torch and the steel pipe blank are kept still, the cutting torch is driven to reciprocate in the first arc-shaped groove based on the combination of the vertical arc of the central axis of the steel pipe blank and the arc on the horizontal plane, so that the cutting torch cuts a round angle at the left-side joint of the first inclined cutting seam and the horizontal cutting seam and at the right-side joint of the second inclined cutting seam and the horizontal cutting seam. Therefore, a gap is reserved when three triangular plates are bent, so that two corners of the triangular plates cannot be extruded with the corners of the adjacent triangular plates. The three triangular plates are positioned at the end points of the grouting pipe section side and can be mutually extruded to cause deformation when being bent.

s23, then the cutting torch 430 moves reversely along the central axis direction of the steel pipe blank 100, and simultaneously the steel pipe blank 100 continues to rotate clockwise so that the cutting torch 430 cuts to the next first cutting point position a along the second cutting point position b to form a second inclined cutting slot 113;
s24, repeating the steps S21, S22 and S23 for a plurality of times to form a complete cutting seam 110;
s3, forming:
s31, respectively moving a plurality of pressing hammers 520 in a forming mechanism 500 arranged on a workbench 200 to a plurality of triangular plates 140 for one stroke so that the plurality of triangular plates 140 bend towards the central axis of the steel pipe blank 100;
s32, enabling the grouting pipe section 120 to reversely move for a distance along the central axis and then stop, and enabling the triangular plates 140 to continue bending by moving the plurality of hammers 520 to the plurality of triangular plates 140 for a secondary stroke larger than the primary stroke;
s33, repeating the steps S31 and S32 to enable the triangular plates 140 to complete bending;
s4, blanking: removing the grouting pipe section 120 to obtain a product;
in step S1, a loading rail 210 is provided on the workbench 200, the loading rail 210 is used for loading the steel pipe blank 100, and two clamping assemblies 310 are symmetrically provided at two sides of the joint of the loading rail 210 and the unloading rail 220;
in step S2, the workbench 200 is provided with a chute 230, and the clamping assembly 310 connected with the scrap section 130 releases the scrap section 130 and falls through the chute 230;
in step S4, a blanking track 220 is provided on the workbench 200, the blanking track 220 is used for blanking the grouting pipe section 120, after the grouting pipe section 120 is loosened by the clamping assembly 310 connected with the grouting pipe section 120, the grouting pipe section 120 is pushed into the blanking track 220 by the operation of the fifth cylinder 600 provided in the workbench 200;
in step S3, the forming mechanism 500 includes a plurality of fourth cylinders 510 disposed on the table 200, and a plurality of hammers 520 are respectively disposed on piston rods of the plurality of fourth cylinders 510.
In this embodiment: when the steel pipe blank 100 slides down from the feeding track 210 to the groove at the joint of the feeding track 210 and the discharging track 220, two clamping assemblies 310 symmetrically arranged on the left and right clamp the two ends of the steel pipe blank 100. Then cutting is started, which is a cutting device for cutting metal materials by using fuel gas and oxygen or gasoline and oxygen, and plasma cutting, high-pressure water cutting and the like can be selected.
The cutting torch 430 moves leftwards along the central axis of the steel pipe blank 100, and the steel pipe blank 100 rotates clockwise under the driving of the grabbing mechanism 300, so that the cutting torch can be matched with the cutting torch to cut from the first cutting point a to the second cutting point b on the steel pipe blank 100, and a first oblique line oblique cutting seam 111 with radian is cut.
Then, the steel pipe blank 100 and the cutting torch 430 stop moving, at this time, the cutting torch 430 is located at the second cutting point b and is also the middle section of the horizontal cutting slit 112, and then the cutting torch 430 reciprocates back and forth along the right arc direction shown in fig. 11, so as to cut the round angle between the second cutting point b and the third cutting point c.
The steel tube blank 100 then continues to rotate clockwise and the torch 430 cuts horizontally from the second cutting point b to the third cutting point c.
Then the steel pipe blank 100 is rotated counterclockwise instead, and the torch 430 is horizontally cut from the third cutting point c to the fourth cutting point d.
Then the steel tube blank 100 is turned clockwise again, the cutting torch 430 returns from the fourth cutting point d to the second cutting point b, and at this time, the cutting torch 430 reciprocates back and forth along the left arc direction shown in fig. 11, so as to cut the round angle between the fourth cutting point d and the second cutting point b.
The steel pipe blank 100 continues to rotate clockwise while the torch 430 moves rightward to cut from the second cutting point b to the next first cutting point a, cutting a diagonal second chamfer slit 113 having an opposite direction.
Finally, the above process is repeated to cut down the grouting pipe section 120 and the waste section 130, and three triangular plates 140 are provided on the grouting pipe section 120. The function of the horizontal slits 112 and the rounded corners is to reduce the deformation amount of the three triangular plates 140 when they are bent and deformed, and to allow space for the deformation of the three triangular plates 140 so that the corners of the three triangular plates 140 are not squeezed together.
After the cutting is completed, the right clamping assembly 310 releases the scrap section 130 so that the scrap section 130 falls into the chute 230, and the left clamping assembly 310 drives the grouting pipe section 120 to move leftwards and rotate so that the triangular plates 140 and the pressing hammers 520 are in one-to-one correspondence, and then the plurality of fourth cylinders 510 arranged circumferentially based on the steel pipe blank 100 drive the plurality of pressing hammers 520 to move radially, and stress is applied to the three triangular plates 140 to bend the three triangular plates. The three hammers 520 are then reset and the steel pipe blank 100 is moved a further distance to the left, the three hammers 520 are then stressed with a further greater stroke, and the three triangular plates 140 are bent into the arc shape shown in fig. 2 by progressively applying a further greater stroke.
Finally, the left clamping assembly 310 releases the grouting pipe section 120, and the fifth cylinder 600 extends the ejecting grouting pipe section 120 to fall into the blanking track 220, so that the whole processing process is completed.
