Description

Technical Field

[0001] The invention relates to the technical field of profile processing, in particular to a composite material shaping device. Background Art

[0002] The pultrusion process is an efficient and large-scale method for producing high-performance fiber composite materials. It is characterized by simple and efficient processes and is suitable for large-scale production of high-performance fiber composite materials. In traditional processing methods, fibers are usually discontinuous, which makes the fiber strength unable to be fully utilized. In contrast, the pultrusion process can best play the reinforcing role of fibers. In most composite manufacturing processes, fibers are discontinuous, which causes a great loss of fiber strength. Even if continuous fibers are wound, the strength is lost to a certain extent due to the bending and overlapping of the fibers. For example, in spiral winding, the tension of the fibers can only reach 75% to 85%. In contrast, in pultrusion, the fibers are not only continuous but also fully unfolded, which is an ideal form for exerting fiber strength. In addition, the pultrusion process has the advantages of small quality fluctuations, high degree of automation, few processes, and short time. The operating technology and environment have little effect on the quality of the product. Therefore, when using the same raw materials, the quality stability of pultruded products is higher than that of other process products.

The three sliding blocks 19 are respectively slidably connected in the two first sliding grooves 5 and one slide groove 3 along the left and right directions. Two sliding ends are arranged in the electric slide rail 28, and the sliding direction of the sliding end of the electric slide rail 28 is the front-to-back direction.

A mold repair hole 101 is arranged on the side where the two outer templates 10 are close to each other, and the two outer templates 10 are symmetrically arranged front to back. The electric slide rail 28 can be the following structure: including a slide rail body, the slide rail body is provided with two groups of support sliders spaced front to back, the lower parts of the two groups of support sliders slide in the slide rail body along the front-to-back direction, and the two groups of support sliders have two groups of cylinders that can be telescopic in the front-to-back direction to drive the front-to-back sliding respectively;

[0034] Preferably, the internal shaping component 7 includes a center frame 11, which is fixedly connected to the left side wall of the installation box 2. The center frame 11 is provided with several groups of internal support components corresponding to the external shaping components 6.

[0037] The driving assembly 4 of the present invention may be an electric telescopic rod along the left and right directions, or may be the following structure;

[0038] The beneficial effects of the above technical solution are:

[0039] In the initial state, the first cylinder 13 is in a contracted state, and the profile is mounted on the inner shaping component 7. The first cylinder 13 is controlled to extend to a preset length, so that the extrusion plate 14 is in close contact with the inner wall of the profile, providing support for the profile while shaping the inner wall of the profile, ensuring the flatness of the inner wall of the profile and correcting the straightness of the profile.

The first cylinder 13 controls the extension and contraction of the extrusion plate 14, which facilitates the disassembly and assembly of the non-uniform cross-section profile, avoids the difficulty in installing the profile due to different cross-sectional shapes, and avoids the increased difficulty in loading and unloading due to the deformation of the inner wall of the profile, thereby improving the disassembly and assembly efficiency of the profile. The heating component is used to heat the extrusion plate 14, which facilitates the deformation of the profile, and avoids the rebound of the profile after shaping, thereby improving the shaping effect of the profile.

The inner wall of the locking hole 15 is fixedly connected with a mounting frame 1 24. Four locking blocks 25 are installed on the mounting frame 1 24. The four locking blocks 25 are respectively installed on the front, back, left and right sides of the mounting frame 1 24. The right end of the locking block 25 contacts the conical surface 23. The left side wall of the installation box 2 is fixedly connected with a mounting frame 26. The mounting frame 26 is slidably connected with a movable ring 1 27 in the left and right directions. A spring 36 is fixedly connected between the right surface of the movable ring 1 27 and the left surface of the mounting frame 26. The right side wall of the movable ring 1 27 is fixedly connected with two sliding rods 28. The sliding rods 28 slide through the installation box 2 along the left and right directions.

[0043] The beneficial effects of the above technical solution are:

[0044] In the initial state, the electric telescopic rod 21 is in an extended state. As the profile is placed in place, the right end of the profile will squeeze the movable ring 27, and squeeze the movable ring 27 to the right, so that the two sliding rods 28 squeeze the two trigger blocks 30 respectively, so that the two trigger blocks 30 are close to each other, and the sliding rod 16 is squeezed by the inclined surface 31, so that the sliding rod 16 moves to the left in the locking hole 15, so that the conical block 22 is squeezed between the four locking blocks 25. Under the action of the conical surface 23, the four locking blocks 25 move away from each other, locking the left and right movement of the profile, avoiding the left and right position of the profile changing during the shaping process, affecting the shaping effect, and at the same time avoiding the profile from escaping from the shaping device and causing danger.

[0045] When the shaping is completed, the electric telescopic rod 21 contracts and the conical block 22 is pulled out from between the four locking blocks 25. Under the action of the spring 2 34, the locking block 25 returns to the initial position. At the same time, under the action of the spring 36, the movable ring 27 returns to the initial position and pushes out the profile to facilitate the manipulator to clamp the profile. Under the action of the spring 20, the sliding rod 16 moves to the right and squeezes the trigger block 30 to return the trigger block 30 to the initial position. After that, the electric telescopic rod 21 returns to the extended state, which is convenient for the continuous shaping action and improves the shaping efficiency.

[0046] By setting the second inclined plane 35, when the profile does not reach the target position, a rightward pushing force is provided to the profile to ensure that the profile is installed in place, thereby avoiding failure of the locking device caused by the profile not being installed in place, thereby affecting the shaping efficiency.

After the shaping of a cross-section segment is completed, when the outer shaping component 6 needs to be replaced, when the driving block 39 moves to the replacement position of the outer shaping component 6, the guide rail 40 is transformed into the high-position segment 402, and the roller 48 moves upward to drive the trigger plate 47 to move upward, so that the upper end of the trigger plate 47 lifts the second end of the rotating plate 52, so that the first end of the rotating plate 52 moves downward, thereby moving the connecting rod 55 downward through the center rod 51, so that the second rod segment 57 is pulled out from the connecting hole 43, and the connecting assembly is connected with the previous outer shaping assembly. 6, and then as the driving block 39 continues to move, the guide rail 40 is transformed into the low section 401. Under the action of the spring four 64, the trigger plate 47 moves downward and no longer moves the rotating plate 52. Under the action of the spring six 59, the first rod segment 56 moves upward and drives the rotating plate 52 back to the initial position. At this time, the spring five 58 is in a compressed state. As the driving block 39 continues to move, the second rod segment 57 is aligned with the connecting hole 43. Under the action of the spring five 58, the second rod segment 57 is inserted into the connecting hole 43, completing the connection between the connecting assembly and the next outer shaping assembly 6.

[0052] By cooperating with the trigger assembly and the connecting assembly, the continuous switching of the external shaping assembly 6 is completed. The switching process does not require the driving block 39 to stop moving, which ensures the continuity of the shaping action, improves the shaping effect, and improves the shaping efficiency. The setting of the roller 48 improves the smoothness of the movement of the trigger plate 47 on the slide groove three 44, and avoids jamming during the shaping process, which affects the shaping effect. Through the setting of the spring five 58, after the first rod segment 56 rises, the second rod segment 57 can be aligned with the connecting hole 43 as the driving block 39 moves, which reduces the accuracy requirement of the driving block 39 movement during the switching process of the external shaping assembly 6, ensuring the smooth switching action. After completing the shaping of a profile, as the driving block 39 moves in the opposite direction, all the external shaping assemblies 6 can be reset to the initial state at the same time in the process of returning to the initial position, without the need for manual reset by the staff, which reduces the labor intensity of the staff and improves the continuity of profile shaping.

[0053] Embodiment 4, on the basis of embodiment 3, as Figure 8 , Fig.12 As shown, the upper surface of the driving block 39 is also provided with two left-right symmetrical extension grooves 61, and a buffer plate 62 is slidably connected in each extension groove 61 along the up-down direction. A U-shaped plate 63 arranged along the left-right direction is provided above each trigger rod 49, and the two ends of the U-shaped plate 63 slide in the up-down direction through the lower surface of the extension groove 61 and are fixedly connected to the lower surfaces of the two buffer plates 62 respectively.

[0054] The beneficial effects of the above technical solution are:

[0055] When the second end of the rotating plate 52 is lifted, the U-shaped plate 63 is also lifted upward at the same time, so that the two buffer plates 62 are extended from the extension groove 61. The two buffer plates 62 are respectively located on the left and right sides of the previous external shaping component 6, thereby avoiding the two external shaping components 6 from colliding and causing damage. At the same time, the buffer plates 62 can drive the two external shaping components 6 to move at the same time after the connecting rod 55 is separated from the connecting hole 43, thereby avoiding the previous external shaping component 6 from stopping too early, resulting in part of the profile not being shaped. The two buffer plates 62 are respectively arranged on the left and right sides of the previous external shaping component 6, which can ensure that the buffering effect can be played both in the outward and return strokes of the shaping process, thereby ensuring the buffering effect.

[0056] When one end of the rotating plate 52 drops, under the action of gravity, the buffer plate 62 falls back into the extension groove 61, and then the first rod segment 56 rises. The second rod segment 57 cannot bounce up under the pressure of the lower surfaces of the two external shaping components 6 (the gap between the two external shaping components 6 is not large enough for the second rod segment 57 to bounce up under the action of the spring five 58). As the driving block 39 continues to move, the second rod segment 57 is aligned with the connecting hole 43. Under the action of the spring five 58, the second rod segment 57 is inserted into the connecting hole 43, completing the connection between the connecting component and the next external shaping component 6.
