[0027] The beneficial effects of the present invention are as follows:

[0028] (1) The profile is placed inside the profile shaping mechanism, and the position of the profile remains unchanged. The adjusting device of the present invention can make the profile shaping mechanism rotate in the pitch direction and the horizontal direction to change the relative position of the profile and the profile shaping mechanism, thereby making the inner wall of the profile shaping mechanism extrude the profile, and finally adjusting the shape of the profile. The profile after the shape adjustment can meet the actual use requirements.

[0029] (2) The adjusting device of the present invention can make the profile shaping mechanism rotate in four directions: upward, downward, leftward, and rightward. Therefore, any side of the profile can be adjusted, which can better adjust the shape of the profile and thus improve the qualified rate of the processed profile.

[0030] (3) The water tank of the present invention is hinged to the base at a position close to the outlet end, and the molding die is also hinged to the base at a position close to the inlet end. The present invention sets a lifting seat at the position where the water tank and the molding die are connected, and the adjustment blocks on both sides below the lifting seat are in a sliding fit with the lifting seat. The two adjustment blocks move toward each other, causing the lifting seat to carry the water tank and the molding die to move upward, so that the water tank and the molding die rotate in the pitch direction to extrude the lower side of the profile, thereby adjusting the shape of the profile. Similarly, when the two adjustment blocks move back to back, the water tank and the molding die extrude the upper side of the profile. The adjustment blocks and the lifting seat of the present invention are in a sliding fit, which can control the displacement of the lifting seat moving up and down within a certain range, and then control the rotation angle of the water tank and the molding die in the pitch direction within a safe range to prevent the profile from being damaged due to excessive rotation angle.

[0031] (4) The slider of the present invention is located between the two screw racks, that is, the movable distance of the slider is limited to between the two screw racks, thereby limiting the rotation angle of the water tank and the molding die in the horizontal direction to prevent the profile from being damaged due to excessive rotation angle.

[0032] (5) The slider of the present invention is fixedly connected to the support, so that the entire horizontal rotation mechanism can move up and down synchronously with the support, and the horizontal rotation mechanism can still adjust the rotation angle of the water tank and the shaping mold during the movement. Therefore, the horizontal rotation mechanism and the pitch rotation mechanism of the present invention cooperate with each other, and can adjust the shape of the profile from multiple sides of the profile at the same time, thereby improving efficiency.

[0033] (6) A bending section is provided on the screw rod frame of the horizontal rotation mechanism of the present invention, and the length of the bending section along the moving direction of the lifting seat is greater than the vertical movable distance of the lifting seat of the pitch rotation mechanism, which can ensure that the screw rod frame is always not detached, thereby better controlling the horizontal rotation angle of the water tank and the molding die.

[0034] (7) The water tank and the shaping mold are softly connected through an accordion-type sealing cover, and the ball head and the shaping mold form a universal joint. The two cooperate with each other, so that the water tank and the shaping mold rotate gradually rather than suddenly, so that in the process of adjusting the shape of the profile, the water tank and the shaping mold can be prevented from damaging the profile due to sudden rotation.

[0035] (8) The horizontal rotating plate and the pitch rotating plate of the present invention cooperate with each other, so that the water tank and the shaping mold can rotate relative to the base. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0056] Example 1

[0057] An automatic adjustment device for profile shaping, such as Figure 1 As shown, it includes the following components:

[0058] The pitch rotation mechanism 2 is used to drive the profile shaping mechanism 4 to rotate relative to the profile 5 located inside the profile shaping mechanism 4 in the pitch direction.

[0059] The horizontal rotation mechanism 3 is used to drive the profile shaping mechanism 4 to rotate relative to the profile 5 located inside the profile shaping mechanism 4 in the horizontal direction.

[0060] The pitch rotation mechanism 2 and the horizontal rotation mechanism 3 cooperate with each other to drive the inner wall of the profile shaping mechanism 4 to extrude the profile 5 so as to adjust the shape of the profile 5 .

[0061] The base 1 is used to support and place the pitch rotation mechanism 2, the horizontal rotation mechanism 3 and the profile shaping mechanism 4. They are introduced below:

[0062] like Figure 1 and Figure 2 As shown, the base 1 includes two guide rails 11 arranged in parallel along the extrusion direction of the profile 5, and fixing plates 13 are respectively fixed on the two guide rails 11 near the front end and the rear end, and a guide seat 12 is fixed at the middle position of the guide rails 11. The end surface of the guide seat 12 facing the profile shaping mechanism 4 is provided with a groove, and the guiding direction of the guide seat 12 is perpendicular to the length direction of the guide rail 11 in the horizontal plane.

[0063] like Figure 2 As shown, the pitch rotation mechanism 2 includes a pitch screw 23, a pitch motor 21 for driving the pitch screw 23 to rotate, a first wire sleeve portion 24 and a second wire sleeve portion 25 which are sleeved on the pitch screw 23 and are arranged opposite to each other, and a lifting seat 26 which is located between the two sets of wire sleeve portions and is arranged along the length direction of the pitch screw 23, and is used to support a screw seat 22 of the pitch screw 23. The screw seat 22 is fixed to the end of the guide seat 12 facing the pitch motor 21, a through hole is formed on the screw seat 22, a bearing is fixed on the inner wall of the through hole, the outer ring of the bearing is fixed on the hole wall of the through hole, and the inner ring of the bearing rotates synchronously with the pitch screw 23.

[0064] like Figure 2As shown, the first thread sleeve portion 24 includes a first thread sleeve 24a that forms a ball screw structure with the pitch screw rod 23, and a first adjustment block 24b that is connected to the first thread sleeve 24a and sleeved on the outside of the pitch screw rod 23; the second thread sleeve portion 25 includes a second thread sleeve 25a that forms a ball screw structure with the pitch screw rod 23, and a second adjustment block 25b that is connected to the second thread sleeve 25a and sleeved on the outside of the pitch screw rod 23;

[0065] like Figure 3 As shown, the upper end surface of the first adjustment block 24b and the upper end surface of the second adjustment block 25b are both provided with inclined surfaces, and the two inclined surfaces respectively form a sliding fit with the corresponding inclined surfaces on the lifting seat 26. The lifting seat 26 is an isosceles trapezoid, and the end surfaces where the two waists of the isosceles trapezoid are located respectively form a sliding fit with the inclined surfaces of the first adjustment block 24b and the second adjustment block 25b. The pitch screw 23 is rotated so that the two first adjustment blocks 24b and the second adjustment blocks 25b move along the length direction of the pitch screw 23, which is used to make the two adjustment blocks adjust the lifting seat 26 to move up and down. A limit member 261 is fixedly provided on the guide seat 12 in the vertical direction. In this embodiment, the limit member 261 is a screw, and the limit member 261 and the lifting seat 26 form a hole-axis match. The lifting seat 26 can move up and down along the limit member 261. During the upward movement of the lifting seat 26, the profile shaping mechanism 4 is prompted to perform a pitch rotation around the hinge point.

[0066] like Figure 2 As shown, the horizontal rotation mechanism 3 includes a horizontal screw rod 34 arranged in a horizontal plane perpendicular to the length direction of the profile shaping mechanism 4, a horizontal motor 33 for driving the horizontal screw rod 34 to rotate, a slider 32 that cooperates with the horizontal screw rod 34 to form a ball screw, and a first screw rod frame 31a and a second screw rod frame 31b located on both sides of the slider 32 and cooperate with the horizontal screw rod 34 to form a hole axis. The ends of the first screw rod frame 31a and the second screw rod frame 31b are bent downward to form a bending section, and the two bending sections are clamped on the outer surface of the base 1, and the length of the bending section along the moving direction of the lifting seat 26 is greater than the movable distance of the lifting seat 26.

[0067] like Figure 1 and Figure 2As shown, the profile shaping mechanism 4 includes a shaping die 41 and a water tank 42 arranged along the extrusion direction of the profile 5, and a linkage mechanism 421 located below the joint between the shaping die 41 and the water tank 42. The shaping die 41 includes a platen 412 and a mold 411 fixed on the platen 412, a mold cavity 411a is arranged inside the mold 411, the end where the mold 411 is connected to the water tank 42 is the outlet end of the mold 411, and the end where the water tank 42 is connected to the mold 411 is the inlet end of the water tank 42. The inlet end of the water tank 42 is provided with an inlet plate 423 communicating with the inside of the water tank 42, the outlet end of the shaping die 41 is provided with a sealing plate 419 communicating with the inside of the shaping die 41, and an accordion-type sealing cover 44 is connected between the inlet plate 423 and the sealing plate 419. The inside of the water tank 42 is provided with shaping plates 422 in sequence along the extrusion direction of the profile 5 , the plate surface of the shaping plates 422 faces the inlet end of the water tank 42 , and the shaping plates 422 are provided with through holes whose size and shape are compatible with the profile 5 .

[0068] The linkage mechanism 421 includes a support 4211 that fits the upper end surface of the lifting seat 26, and a fixing seat 4214 fixed to the lower end surface of the support 4211. Figure 4 and Figure 6 As shown, a ball rod 4215 is arranged along the extrusion direction of the profile 5 and connected to the fixing seat 4214, and a ball head 4216 is arranged at the end of the ball rod 4215. The fixing seat 4214 is located on one side of the lifting seat 26. There is no connection between the fixing seat 4214 and the lifting seat 26. The ball rod 4215 is threadedly connected to the fixing seat 4214. Figure 2 and Figure 4 As shown, a first ball seat 417 is fixed to the lower end surface of the table 412, and a second ball seat 418 is fixed to the lower end surface of the first ball seat 417. Both the first ball seat 417 and the second ball seat 418 are provided with grooves, and the hole groove formed by the two grooves is adapted to the size of the ball head 4216. Assuming that the cross-sectional diameter of the ball rod 4215 is d, and the diameter of the hole groove is D, d and D satisfy the following relationship: The value range of (Dd) / 2 is 2 to 5 mm, so that the rotation angle of the molding mold 41 and the water tank 42 is not less than eight degrees.

[0069] The two guide rails 11 are respectively fixed with fixing plates 13 at positions near the inlet end of the shaping mold 41 and the outlet end of the water tank 42. The fixing plates 13 are connected with universal hinges, such as Figure 2 As shown, the two sets of universal joints each include a pitch rotation plate 433 and a horizontal rotation plate 431. The pitch rotation plate 433 forms a pitch rotation structure with the fixed plate 13 through a pitch rotation axis 434, the horizontal rotation plate 431 below the water tank 42 is fixedly connected to the water tank 42, the horizontal rotation plate 431 below the shaping mold 41 is fixedly connected to the table 412, and each horizontal rotation plate 431 forms a horizontal rotation match with the corresponding pitch rotation plate 433 through a horizontal rotation axis 432.

[0070] The working process of the pitch rotation is as follows: start the pitch motor 21, the pitch motor 21 drives the pitch screw 23 to rotate, and the first wire sleeve part 24 and the second wire sleeve part 25 on both sides below the lifting seat 26 move toward each other. Since the two wire sleeve parts form a sliding surface fit with the lifting seat 26, the two wire sleeve parts move toward each other, which can lift the lifting seat 26 to move upward, and then the lifting seat 26 moves upward against the support 4211. Since the support 4211 is fixedly connected to the inlet end of the water tank 42, the inlet end of the water tank 42 moves upward, and the water tank 42 is near the outlet end and forms a pitch hinge with the fixed plate 13 on the guide rail 11 through the pitch rotation plate 433, so the water tank 42 can perform pitch rotation around the pitch rotation plate 433.

[0071] The lower end of the support 4211 is fixedly connected to a fixed seat 4214, and the fixed seat 4214 is connected to a ball rod 4215 and a ball head 4216. The ball head 4216 extends into a hole groove formed by the first ball seat 417 and the second ball seat 418. During the upward movement of the support 4211, the ball rod 4215 presses against the upper wall of the hole groove, causing the outlet end of the molding die 41 to move upward. Therefore, the molding die 41 can also perform a pitch rotation around the pitch rotation plate 433 below it.

[0072] Since the shaping mold 41 and the water tank 42 are softly connected via the accordion-type sealing cover 44, the two are allowed to rotate successively during the rotation process.

[0073] The slider 32 is fixedly connected to the support 4211, so that when the support 4211 moves upward, the horizontal rotation mechanism 3 where the slider 32 is located also moves upward, so that during the pitch rotation, the slider 32 can also rotate horizontally, so that the pitch rotation and the horizontal rotation can cooperate with each other. The two screw rods of the horizontal rotation mechanism 3 will never leave the guide rail 11 during the upward movement.

[0074] The working process of horizontal rotation is as follows: the horizontal motor 33 is started, and the horizontal motor 33 drives the horizontal screw 34 to rotate, so that the slider 32 moves along the length direction of the horizontal screw 34. The movement of the slider 32 can carry the support 4211 to move horizontally, and the movement of the support 4211 causes the shaping mold 41 and the water tank 42 to rotate horizontally. A guide hole 4213 is opened on the support 4211, and a guide member 4212 is fixed on the lifting seat 26. The guide member 4212 and the guide hole 4213 cooperate with each other, so as to allow the support 4211 to move horizontally relative to the lifting seat 26.

[0075] like Figure 5As shown, when the lower surface of the profile 5 is bent, the pitch motor 21 is started, and under the cooperation of the lifting seat 26, the first wire sleeve part 24, and the second wire sleeve part 25, the water tank 42 and the shaping mold 41 rotate upward, while the profile 5 remains stationary. When the water tank 42 and the shaping mold 41 rotate upward, they will squeeze the bent part of the profile 5 to adjust the shape of the profile 5.

[0076] Example 2

[0077] The profile shaping mechanism 4 only includes a water tank 42, the outlet end (one end) of the water tank 42 is universally hinged with the base 1, and the inlet end (the other end) of the water tank 42 is moved up and down by moving the lifting seat 26 up and down, so that the water tank 42 can pitch and rotate around the hinge point with the base 1.

[0078] The slider 32 moves along the length direction of the horizontal screw rod 34 , driving the inlet end (the other end) of the water tank 42 to move horizontally, so that the water tank 42 rotates horizontally around the hinge point with the base 1 .

[0079] Example 3

[0080] The profile shaping mechanism 4 only includes a shaping die 41, and the inlet end (one end) of the shaping die 41 forms a universal hinge with the base 1. The support 4211 is fixed on the shaping die 41, and the support 4211 can move horizontally relative to the lifting seat 26. The lifting seat 26 is moved up and down to realize the up and down movement of the support 4211, and then the outlet end (the other end) of the shaping die 41 is moved up and down, so that the shaping die 41 can pitch and rotate around the hinge point with the base 1.
