Description

Technical Field

[0001] The invention relates to the manufacturing of half-tube forming machine equipment, in particular to a sealing half-tube forming machine. Background Art

[0002] The traditional method of making a half-tube is: first draw a spiral line on the actual position of the head as required, then divide the round tube into multiple sections, and bend each section into arcs according to the actual position drawn on the head. Then use plasma or gas cutting to cut the arcs into arc-shaped semi-circular tubes. Since we usually use manual gas cutting, the cutting edges are rough and the quality is very unstable. The other half that is cut can only be discarded, resulting in a large waste of materials. At present, pressure vessels are made of stainless steel and other materials. Such materials are expensive. The cost of using round tubes is extremely high. In addition, the edges of the semi-circular tubes we cut are extremely uneven and have oxidation slag, etc., which need to be manually polished.

The first driving gear 103 and the first driven gear 104 are meshed. The first driven gear 104 is arranged on the feed shaft 105.

[0053] That is, when the first motor 102 is in operation, the first driving gear 103 and the first driven gear 104 are used to drive the feed shaft 105 to rotate.

[0056] In addition, the fixed outer plate 206 is also provided with an outer step surface 207 for opening on the outer shell 201 to form a pre-fixation for easy installation.

[0060] The half-tube forming part 2 further comprises a transmission member, which is connected to the driving member and the roller to provide full-range power for the half-tube.

[0061] Furthermore, if Figure 4 As shown, the transmission member includes a driving driving wheel 211 and a driving driven wheel 210: a driving driven wheel 210 is arranged on the outer side of one of the mounting blocks 209 of each convex wheel 203, a driving driving wheel 211 is meshed between two adjacent driving driven wheels 210, and one of the driving driving wheels 211 is connected to a second motor 212 ( Figure 1 As shown, the rotation axis of the second motor 212 is the X-axis. As the second axis of the 4-axis CNC device, the second motor 212 provides full-range power to the entire device by driving the active wheel 211 and the driven wheel 210. No forward power source is set at the feeding end and the discharging end of the entire device, so as to avoid the side effect of accumulation caused by the power source at the feeding end to the half-tube forming, and also avoid the side effect of pulling caused by the power source at the discharging end to the half-tube forming, so as to ensure that the shape of the half-tube is intact and the product is good.

[0062] like Figure 1 As shown, the discharge portion 3 is erected using a base, etc., one end of which is connected to the discharge port of the half-tube forming portion 2, and the other end is connected to the feed port of the three-dimensional forming portion 4. The discharge portion 3 serves as an intermediate transition section. Firstly, the length is long enough to provide sufficient space for the discharge to prevent half-tube accumulation, and secondly, further shaping is performed in the discharge portion 3.

[0063] like Figure 8 FIG. 4 is a side view of the discharge portion 3. Fig. 9 Shown is Figure 8 A-A cross-sectional diagram, as shown in Fig.10 Shown is Figure 8 The top view decomposition diagram of Fig.11 Shown is Figure 8 The bottom perspective exploded schematic diagram, wherein the discharge portion 3 includes a first shell 301, a second shell 302, and an internal tube 303, the internal tube 303 is placed in the second shell 302, and the first shell 301 is covered on the second shell 302 to form a discharge cavity M3; Fig. 9The inner diameter of the first shell 301 is equal to the outer diameter of the half tube, the inner diameter of the second shell 302 is equal to the inner diameter of the half tube, and the outer diameter of the inner tube 303 is equal to the inner diameter of the half tube, so that a discharge cavity M3 is formed between the first shell 301, the second shell 302, and the inner tube 303. In addition, the setting of these radius dimensions can be set according to the required size of the half tube.

[0064] One end of the discharge cavity M3 is connected to the molding cavity M2, and the central axis of the discharge cavity M3 is colinear with the central axis of the molding cavity M2 to facilitate rotational movement in the X-axis direction.

Before the change, the outer wall of the half pipe is attached to the outer wall of the first shell 301, and the inner wall is attached to the inner wall of the half pipe. It is attached to the outer wall of the built-in tube 303 for advancement, and the inner and outer walls are fully fitted, resulting in large friction, which is not conducive to the advancement of the half-tube, increases the energy consumption of the power source, and affects the quality of the half-tube. After the transformation, the outer wall of the half-tube is attached to the first protrusion 309, and the inner wall is attached to the third protrusion 308 for advancement. The first protrusion 309, the third protrusion 308 and the half-tube are attached at intervals, which reduces the attachment area, reduces friction, is conducive to the advancement of the half-tube, reduces the energy consumption of the power source, and ensures the quality of the half-tube.

The second rotating part includes a motor 401. The rotation axis of the motor 401 is the T2 axis. As the third axis of the 4-axis CNC device, the second rotating part is connected to the three-dimensional discharge head 409 and drives the three-dimensional discharge head 409 to rotate around the X axis, so that the three-dimensional discharge cavity M4 rotates around the X axis, that is, the angle change of the T2 axis causes the angle change of the three-dimensional discharge cavity M4 on the X axis. The second rotating part is arranged on the seat, and the loading part is connected to the second rotating part to realize rotational motion, and the seat is connected to the arc adjustment part 5 to realize the Z-axis motion of the three-dimensional discharge cavity M4.

When the curvature adjustment part 5 drives the three-dimensional discharge cavity M4 to move along the Z axis, the second rotating member moves along the Z axis, so that T1 and T2 are not colinear. At this time, the three-dimensional discharge cavity M4 and the discharge cavity M3 are not colinear, and there is a deviation between the three-dimensional discharge cavity M4 and the discharge cavity M3, and the angle changes, that is, the rotation of T1 and T2 adjusts the angle of the formed half-tube discharge, and the Z-axis straight line adjusts the curvature of the three-dimensional product forming.

[0072] Further, the loading part adopts cylindrical gear 403, such as Fig.13 FIG. 4 is an exploded schematic diagram of the installation position of the cylindrical gear 403.

[0075] like Fig.12 and Fig.13 As shown, the second rotating member includes a second driving member, a second gear 402 ( Fig.13 As shown, the second driving member is fixed on the base body using a motor 401, and the second gear 402 is engaged with the cylindrical gear 403 to drive the cylindrical gear 403 to perform reciprocating rotation along the X-axis.

[0076] Among them, when the motor 401 is in operation, the second gear 402 is used to drive the cylindrical gear 403 to rotate around the center of the circle, and the first fixed plate 404 and the first guide column 405 remain relatively fixed. Under the action of the first guide column 405 and the guide groove 406, the cylindrical gear 403 rotates, and rotates around a fixed track (guide groove 406), ensuring that the movement of the cylindrical gear 403 is accurate and will not deviate, thereby ensuring the accurate movement of the three-dimensional discharge head 409 and the accuracy of the half-tube discharge to form a three-dimensional product.

[0080] Working principle:

[0081] Prepare NC programs according to drawings;

[0082] like Fig.17 Shown is Figure 1 The cross-sectional schematic diagram shows that a suitable steel strip coil is first put into the base material coil for unloading, the base material enters from the feed cavity M1 of the feed part 1, passes through the feed shaft 105 and enters the forming cavity M2 of the half-tube forming part 2, and the base material is formed into a half-tube by multiple groups of rollers. At the same time, the power source provided in the half-tube forming part 2 provides the power for the half-tube to move forward; the rollers squeeze the base material to form a half-tube with the same shape as the forming cavity M2, and the rollers convey the half-tube forward;

[0083] After the half-tube is formed and discharged from the half-tube forming part 2, it enters the discharge cavity M3 of the discharge part 3 and moves forward in the discharge cavity M3 until it is discharged;

[0084] Initially, the discharge chamber M3 and the three-dimensional discharge chamber M4 are coaxial, so that the half-tube enters the three-dimensional discharge chamber M4 of the three-dimensional discharge head 409 after coming out of the discharge chamber M3. As the half-tube is continuously discharged, the Z-axis position of the curvature adjustment part 5 is adjusted so that the discharge chamber M3 and the three-dimensional discharge chamber M4 are not coaxial, resulting in mutual offset, thereby controlling the diameter curvature of the bending side of the half-tube, and at the same time adjusting the T1 angle of the first rotating part and the T2 axis angle of the second rotating part, thereby adjusting the angle of the half-tube, wherein the T2 axis rotation angle: the second rotating part is used to control the rotation of the cylindrical gear 403, the T1 axis rotation angle: the first rotating part is used to control the rotation of the feeding part 1, the half-tube forming part 2, and the discharge part 3, and the first rotating part rotates back and forth within the angle range of 90° to control the horizontal angle of the half-tube discharge and guide the discharge direction of the spiral half-tube.

[0085] At the same time, the servo motor of the curvature adjustment part 5 is controlled to move, so that the three-dimensional discharge head 409 reciprocates along the Z axis straight line, so that the half pipe forms a spiral three-dimensional state while the curvature changes;

[0086] Use the prepared arc mold plate and angle plate to check the bending curvature of the spiral half-tube at any time, and fine-tune the CNC system data in time to make the finished product consistent with the drawing.
