[0041] The clamping assembly 2 is used to clamp the profile, such as Figure 1 and Figure 2As shown, a vertical second jacking member 23 is provided on the top of the base 13, that is, the second jacking members 23 are arranged in rows, and the second jacking members 23 in each row are arranged along the width direction of the pultrusion channel. It is achievable that a plurality of grooves distributed in a matrix are provided on the top surface of the base 13, and the lower ends of the second jacking members 23 are embedded in the corresponding grooves.

[0042] Optionally, the first lifting member 22 and the second lifting member 23 both include a straight rod structure and an electric telescopic rod, and the straight rod structure drives its own lifting movement through the electric telescopic rod fixedly connected to it.

[0043] It should be noted that the arrangement of the first lifting members 22 and the second lifting members 23 is not limited, for example, they can be arranged evenly. Figure 3 As shown, the two closest first lifting members 22 or second lifting members 23 in two adjacent columns are arranged along the length direction of the pultrusion channel, or are staggered, and the line connecting the two closest first lifting members 22 or second lifting members 23 in two adjacent columns has a non-zero angle with the length direction of the pultrusion channel, as long as the pultrusion requirements of the preset profile can be met; further, the control mode of each first lifting member 22 is not limited, the first lifting members 22 or second lifting members 23 in a column are synchronously controlled, and the first lifting members 22 or second lifting members 23 in each column are independently controlled, or the first lifting members 22 or second lifting members 23 in a column are all independently controlled, and the first lifting members 22 or second lifting members 23 in each column are independently controlled, etc.

[0044] When in use, the profile is inserted into the pultrusion channel along the length direction, the first lifting member 22 is started, so that the upper end of each first lifting member 22 abuts against the lower surface of the profile, the first telescopic member 21 is started to push the pressing seat 12 down, so that the first lifting member 22 is close to the upper surface of the profile, and then the first lifting member 22 is started, so that the lower end of the second lifting member 23 abuts against the upper surface of the profile, thereby achieving the clamping of the profile.

There is no need to frequently replace the clamping tool during the production of the variable-section profile, which effectively reduces the operational difficulty during the production of the variable-section profile. The clamping tool is applicable to a wide range of profile types and has strong versatility.

[0046] On the basis of the above embodiment, the base 13 is connected to the mounting seat 11 through the guide rod 3 , and the guide rod 3 passes through the pressing seat 12 .

[0047] like Figure 1 As shown, a guide rod 3 is arranged between the base 13 and the mounting seat 11. The guide rod 3 is arranged vertically parallel to the first compression member, the first lifting member 22 and the second lifting member 23, and the lower end of the guide rod 3 is fixedly connected to the base 13, and the upper end is fixedly connected to the mounting seat 11; a vertical through hole is opened on the pressing seat 12 for the first compression member to pass through, so that the guide rod 3 can guide the pressing seat 12 to move smoothly in the longitudinal direction.

[0048] Based on the above embodiment, the second lifting member 23 includes a first rod-shaped structure and a second telescopic member. The top of the base 13 is fixedly connected to a first mounting plate 14. Each first rod-shaped structure slides through the first mounting plate 14. The second telescopic member is arranged on the base 13, and each second telescopic member cooperates with the corresponding first rod-shaped structure.

[0049] like Figure 1 As shown, the first mounting plate 14 is fixedly connected to the top of the base 13 by welding or bolting, the first telescopic member 21 is vertically arranged on the base 13, and several first rod-like structures in the second lifting member 23 can slide through the first mounting plate 14, and there is a gap between the base 13 and the first mounting plate 14, leaving sufficient room for movement for the first rod-like structure and the second telescopic member.

[0050] like Figure 3 As shown, each first rod-shaped structure is arranged vertically, and the upper end of the second telescopic member cooperates with the lower end of the corresponding first rod-shaped structure. Optionally, the second telescopic member is fixedly connected to the corresponding first rod-shaped structure. When in use, the upper end of the second telescopic member extends or retracts to drive the first rod-shaped structure to rise or fall. Optionally, the second telescopic member is arranged relative to the corresponding first rod-shaped structure. When in use, the upper end of the second telescopic member extends to push the first rod-shaped structure to rise, and the first rod-shaped structure can be lowered under the extrusion of the profile. With such an arrangement, the structure of the clamping tool is simple and reasonable, easy to assemble, and easy to change the control mode of each first rod-shaped structure by replacing the connection structure between the second telescopic member and the first rod-shaped structure.

[0051] Based on the above embodiment, the first lifting member 22 includes a second rod-shaped structure and a third telescopic member. The bottom of the pressing seat 12 is fixedly connected to a second mounting plate 15. Each second rod-shaped structure slides through the second mounting plate 15. The third telescopic member is arranged on the pressing seat 12, and each third telescopic member cooperates with the corresponding second rod-shaped structure.

[0052] Similarly, if Figure 1 As shown, the second mounting plate 15 is fixedly connected to the bottom of the top pressing seat 12 by welding or bolting, and the third telescopic member is vertically arranged on the top pressing seat 12. The plurality of second rod-shaped structures in the first lifting member 22 can slide through the second mounting plate 15, and there is a gap between the top pressing seat 12 and the second mounting plate 15, leaving sufficient activity space for the second rod-shaped structures and the third telescopic member, as shown in FIG. Figure 3 As shown, each second rod-shaped structure is arranged vertically, and the lower end of the third telescopic member cooperates with the upper end of the corresponding second rod-shaped structure, so as to push the second rod-shaped structure to be lowered. With such arrangement, the structure of the clamping tool is simple and reasonable, easy to assemble, and easy to change the control mode of each second rod-shaped structure by replacing the connection structure between the third telescopic member and the second rod-shaped structure.

[0053] Preferably, Figure 3 As shown, the top end of the first rod-shaped structure and the bottom end of the second rod-shaped structure are both ball head structures. Such an arrangement is conducive to ensuring the surface quality of the profile.

[0054] In some embodiments, each first lifting member 22 in each column of first lifting members 22 is connected to the same third telescopic member. When in use, each first lifting member 22 in the same column will rise or fall synchronously under the drive of the third telescopic member to which it is connected. Since the shape and height of the surface of the same cross-section of the profile along the width direction are usually the same, the first lifting member 22 in this embodiment has a certain versatility, and the structure of the clamping tool is simple and easy to control.

[0055] In some embodiments, each second lifting member 23 in each column of second lifting members 23 is connected to the same second telescopic member. Similarly, when in use, each second lifting member 23 in the same column will rise or fall synchronously under the drive of the second telescopic member to which it is connected. In this embodiment, the second lifting members 23 have a certain versatility, which further simplifies the structure of the clamping tooling and reduces the control difficulty.

[0056] In some embodiments, the first telescopic member 21 is a hydraulic cylinder; in some embodiments, the second telescopic member is a hydraulic cylinder; in some embodiments, the third telescopic member is a hydraulic cylinder. With such an arrangement, the clamping tool has a stronger performance in clamping the profile.

[0057] In addition to the above-mentioned clamping fixture, the utility model also provides a pultrusion molding machine with flexible clamping and self-adaptive clamping force, which includes the clamping fixture disclosed in the above-mentioned embodiment, and the pultrusion molding machine also includes a workbench 4, a drive motor, a speed detector 6 and a controller. Among them, the top surface of the workbench 4 is provided with a rotatable screw 5 in the horizontal direction, and the screw 5 is connected with at least two clamping fixtures with flexible clamping and self-adaptive clamping force to drive each clamping fixture with flexible clamping and self-adaptive clamping force to move in the horizontal direction; the output end of the drive motor is connected to the screw 5; the speed detector 6 is arranged on the workbench 4, which is used to detect the pultrusion parameters of the profile; the first telescopic member 21, the first jacking member 22, the second jacking member 23, the drive motor and the speed detector 6 are all connected to the controller signal.

[0058] like Figure 4 As shown, the workbench 4 can adopt a box structure or a table structure, and a rotatable screw 5 is arranged above the workbench 4, and the screw 5 extends in the transverse direction. At least two of the above-mentioned clamping tools are arranged in the transverse direction above the workbench 4. The profile can be clamped by two clamping tools arranged at intervals, and the profile can be stably pulled to move laterally. The base 13 in the clamping tool is threadedly matched with the screw 5, so the screw 5 can drive the clamping tool to move left or right by rotating forward or reverse.

[0059] Preferably, a lead screw 5 is provided on each side of the workbench 4, and the two lead screws 5 are parallel to each other so as to stably support and clamp the tooling.

[0060] The output end of the driving motor is connected to one end of the screw 5 to drive the screw 5 to rotate. The driving motor can be a servo motor or a stepper motor, etc., so that the speed and direction of the driving motor and other parameters can be adjusted by the controller, and the moving speed of the clamping tooling that cooperates with the screw 5 can be converted by the controller according to the speed of the driving motor.

[0061] The speed detector 6 is used to detect the pultrusion parameters of the profile in real time. It can be set on the top surface and side of the workbench 4. It can be realized that the speed detector 6 uses a speed sensor to directly obtain the real-time pultrusion speed of the profile. Of course, any other type of speed detector 6 can also be used as long as it can meet the above functions.

[0062] When in use, the controller compares the real-time pultrusion speed with the moving speed of the clamping fixture. When the real-time pultrusion speed is inconsistent with the moving speed of the clamping fixture, the profile will "slip". Then, the controller can send a signal to increase the clamping force to the first telescopic member 21, the first jacking member 22, and the second jacking member 23 until the "slipping" of the profile stops. The pultrusion molding machine has a high degree of automation and can automatically adjust the clamping force as needed, effectively reducing the occurrence of the "slipping" phenomenon, which is conducive to ensuring the quality of the profile, and is conducive to ensuring the stability of the profile pultrusion production process, and effectively improving the stability and efficiency of pultrusion production.

[0063] Furthermore, the controller can set a safe pressure range according to the compressive resistance index of the produced profile. According to the number of the selected first lifting members 22 and the second lifting members 23 and their contact area with the profile, the preset pressure range of each first lifting member 22 and each second lifting member 23 can be obtained after data processing by the controller. Then, while preventing the "slipping" phenomenon from occurring, the pressure values ​​of the first lifting members 22 and the second lifting members 23 can be controlled within a safe range to prevent the profile from being deformed by pressure, so as to ensure the quality of the profile.

[0064] On the basis of the above-mentioned embodiment, the screw 5 is a ball screw. With such arrangement, the pultrusion machine can pull the profile more stably, which is beneficial to improving the quality of the profile.

[0065] On the basis of the above embodiment, protective nets 7 are provided on both sides of the top of the workbench 4, and a clamping tool with flexible clamping and adaptive clamping force is located between the two layers of protective nets 7. Figure 4 As shown, when in use, the clamping tool moves in the space between the two layers of protection nets 7. Such an arrangement is beneficial to protecting the pultrusion machine from external influences during operation and is beneficial to protecting the safety of the operator.

[0066] It should be noted that the type of the protective net 7 is not limited, such as a wire net or a nylon net, etc., as long as the above functions can be achieved.

[0067] On the basis of the above embodiment, the speed detector 6 is a length counter. In this embodiment, the speed detector 6 adopts a length counter, and the real-time pultrusion speed of the profile can be obtained after being processed by the controller. Such a setting has a lower cost.

[0068] On the basis of the above embodiment, it further includes a mold installation unit 8 and a cutting unit 9 . The mold installation unit 8 is located at the starting section of the workbench 4 , and the cutting unit 9 is located at the end of the workbench 4 .

[0069] like Figure 4As shown, a mold installation unit 8 is provided at the left end of the workbench 4 to install a preset extrusion mold for extruding and producing a profile with a preset cross-sectional shape; a cutting unit 9 is provided at the right end of the workbench 4 to cut the extruded long strip profile into profiles of a preset length. When in use, after the profile is extruded, it moves stably to the right end under the clamping and traction action of the clamping tooling, and is separated into profiles of a preset length by the cutting unit 9.

[0070] It is worth noting that the mold installation unit 8 and the cutting unit 9 are relatively mature existing technologies and will not be described in detail herein.

[0071] It should be noted that the relational terms such as "first" and "second" mentioned above are merely used to distinguish one entity from other entities, and do not necessarily require or imply any actual relationship or order between these entities; the "upper surface, lower surface, top, bottom" and the directional words "upper, lower, left, right" mentioned above are all defined based on the drawings in the specification.

[0072] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0073] The above is a detailed introduction to the pultrusion machine with flexible clamping and adaptive clamping force provided by the utility model. This article uses specific examples to illustrate the principle and implementation method of the utility model. The description of the above embodiment is only used to help understand the method and core idea of ​​the utility model.
