[0031] Example 1

[0032] The present application utilizes a strip-shaped planar metal plate or arc plate to press a roller shaft groove section blank with continuous spiral grooves, to realize one-time winding forming of spiral grooves, from which a spiral groove section blank is formed. Figures 1-4 It can be seen that the technical scheme comprises a forming mechanism, a stroke guide mechanism, a machine base 9, and a support frame 1 fixedly connected to the machine base.

[0033] The die roller shaft 3 is composed of a die section 3a and a guide section 3b, the die section 3a is provided with a spiral groove around the shaft line of the roller shaft 3, and a workpiece positioning mechanism is arranged in the spiral groove on the free end side of the die section 3a.

[0034] The guide section 3b of the die roller shaft 3 is installed on the machine base 9 through the shaft sleeve seat 4, so that the die roller shaft 3 rotates around the shaft in the shaft sleeve seat 4 while moving axially along the center line of the die roller shaft; the end of the die roller shaft 3 is provided with a connecting seat connected to an external power source.

[0035] The main pressing roller 2 is assembled on the support frame 1 through a roller frame and forms a rolling and winding mechanism with the die section 3a of the die roller shaft; the convex roller surface of the main pressing roller 2 cooperates with the spiral groove of the die roller shaft 3; an adjusting device for adjusting the pressing depth of the roller is arranged between the roller frame of the main pressing roller 2 and the support frame 1, which can be realized by using a conventional structure such as a lead screw.

[0036] The stroke guide mechanism for controlling the rotation and axial stroke of the die roller shaft is arranged between the die roller shaft 3 and the machine base 9 or the support frame 1, and the stroke guide mechanism is composed of a spiral guide groove and a guide block 8 which is clamped and slidably matched with the spiral guide groove.

[0037] As a preferred solution, the helical groove of the mold roller shaft mold segment 3a is directly used as a helical guide groove in this embodiment, and the guide block 8 is fixed on the frame 1 (or support frame). It should be ensured that the horizontal position of the guide block 8 is between the horizontal position (horizontal projection) of the shaft sleeve seat 4 and the main pressing roller 2. The guide block 8 is in sliding fit with the helical groove of the mold roller shaft. The contact surface of the guide block 8 and the helical groove of the mold roller shaft is matched to ensure good contact and sliding between them. The guide block 8 can also support the mold segment 3a to prevent the mold roller shaft from deforming under stress.

[0038] In addition, the helical guide groove can also be arranged on the guide segment 3b of the mold roller shaft, that is, the helical guide groove is arranged on the cylindrical surface of the guide segment around the axis, and the lead and rotation direction of the helical guide groove are the same as those of the helical groove of the mold segment 3a of the mold roller shaft. The guide block 3 is fixedly connected with the frame (or support frame) and is in sliding fit with the helical guide groove.

[0039] The external power of this embodiment adopts a set of driving units 5 fixed on the sliding seat 6. The sliding seat 6 is slidingly connected with the base 9 through the guide rail 7 (or slide rod). The guide rail (or slide rod) is parallel to the mold roller shaft, so that the driving unit can translate along the guide rail 7 with the sliding seat 6. The driving unit is composed of a motor and a speed reduction mechanism. The power output end of the driving unit is connected with the connecting seat of the mold roller shaft 3 through a universal joint mechanism.

[0040] In order to ensure that the strip-shaped metal plate (flat plate or arc-shaped groove plate) enters the main pressing roller 2 and the groove of the mold roller shaft smoothly and accurately, a feeding limiting mechanism is arranged on the support frame 1 body and opposite to the forming mechanism. The feeding limiting mechanism is composed of a set of limiting rollers 10 assembled on the feeding side of the forming mechanism. In this embodiment, four limiting rollers 10 are arranged in a rectangular shape to form a workpiece passage, and the number and shape of the limiting rollers are determined according to the workpiece to be processed. This can ensure smooth feeding and prevent the workpiece from being displaced during extrusion and shaping.

[0041] The working principle and process of the device will be described below by taking a groove plate blank subjected to arc pressing as an example.

[0042] Thicker metal plates can be pressed to form groove plate blanks by using a pressing device. During operation, the groove plate is first passed through the workpiece passage formed by the limiting rollers 10 and is lapped with the mold segment of the mold roller shaft. The end of the groove plate is fixedly connected with the helical groove by using the workpiece positioning mechanism.

[0043] The structure of the workpiece positioning mechanism in this embodiment is that a positioning hole is arranged in the bottom of the spiral groove at the free end of the mold segment 3a, and the end of the groove-shaped plate is fixed in the groove by bolts or pins; the main pressing roller 2 is adjusted to enter the arc-shaped notch of the groove-shaped plate and is pressed tightly; the motor of the driving unit is started to drive the mold roller shaft to rotate; under the action of the stroke guide mechanism (the guide block 8 acts as a screw nut), the mold roller shaft rotates and simultaneously translates axially along the center line of the roller shaft in the shaft sleeve seat 4 to one side of the mold segment; at this time, the driving unit moves synchronously with the mold roller shaft along the guide rail, so that the groove-shaped plate is wound on the spiral groove of the mold segment 3a, as shown in Figure 4 .

[0044] When the groove-shaped plate blank is completely wound on the mold segment 3a to form a spiral groove blank segment with a continuous notch, the workpiece positioning mechanism is released, the spiral groove blank segment is clamped, and the motor is started in reverse direction, so that the mold roller shaft rotates reversely and moves reversely to reset, and the spiral roller blank segment is removed from the mold segment to complete the forming operation. Since the workpiece is accurately positioned and always clamped during the entire shaping process, the spiral notches are integrated neatly and tightly, which ensures the accuracy of the spiral groove blank segment and eliminates the need for post-shaping, thereby greatly improving the production efficiency and product quality.

[0045] Embodiment 2

[0046] From Figure 5 It can be known that the difference between this embodiment and embodiment 1 is that this embodiment further comprises at least one set of arc pressing mold group, the arc pressing mold group is composed of a set of cooperating male mold pressing roller and female mold pressing roller, the arc pressing mold group is assembled on the support frame 1 and located at the feeding side of the forming mechanism, as shown in Figure 5 In this embodiment, two sets of arc pressing mold groups are arranged at the feeding side of the forming mechanism, including a first arc pressing mold group 12 composed of a first male mold pressing roller 12a and a first female mold pressing roller 12b, and a second arc pressing mold group 13 composed of a second male mold pressing roller 13a and a second female mold pressing roller 13b, and the two male mold pressing rollers and the female mold pressing rollers are connected with the external power device such as the motor through a conventional transmission device.

[0047] After the two arc pressing mold groups press the planar strip-shaped plate to form an arc-shaped notch structure by the male and female mold pressing rollers with different roller surface shapes (curvatures), the planar strip-shaped plate enters the forming mechanism, and the plate is formed by one-time completion of the arc forming and winding.

[0048] The other technical features of this embodiment are the same as those of embodiment 1.

[0049] Embodiment 3

[0050] From Figure 6The difference between the embodiment and the embodiment 2 is that the embodiment further comprises a shaping roller 14 for shaping the auxiliary helical groove blank section. The shaping roller 14 is assembled on the support frame or the machine base through a roller frame and is located at the discharging side of the forming mechanism. The shaping roller 14 cooperates with the helical groove of the die roller shaft and performs secondary pressing on the workpiece wound on the die section 3a, so as to avoid position deviation of the workpiece during shaping. An adjusting device is arranged between the roller frame of the shaping roller 14 and the support frame 1 or the machine base to adjust and control the pressing depth of the roller.

[0051] The other technical features of the embodiment are the same as those of the embodiment 2.

[0052] Embodiment 4

[0053] The difference between the embodiment and the embodiment 1 is that the stroke guide mechanism is structured in that the shaft sleeve seat 4 is threadedly connected with the guide section 3b, and the lead and the rotation direction of the connecting thread are the same as those of the helical groove of the die section 3a of the die roller shaft.

[0054] Another difference between the embodiment and the embodiment 1 is that the feeding limiting mechanism adopts a clamp installed at the feeding side of the forming mechanism to form a clamping opening or a workpiece passage, so as to ensure accurate and smooth feeding.

[0055] In addition, a connecting position of a lever or a crank can be arranged at the connecting seat of the die roller shaft, so that the strip-shaped plate is wound and shaped by manual stirring. The structure is suitable for processing small batch helical groove blank sections with low labor intensity.

[0056] Finally, it should be noted that the above embodiments are used to illustrate the technical solutions of the present application rather than limit the same. The skilled in the art can modify the embodiments or replace some technical features with equivalent ones without departing from the essence of the technical solutions of the present application, which should be covered in the scope of the present application.
