Description

Technical Field

[0001] The invention belongs to the technical field of profile processing equipment, and specifically refers to a steel die fixing device for a profile bending machine. Background Art

[0002] A stretch-bending machine is a metal processing equipment, which is mainly used to bend metal materials into the desired shape. Stretch-bending machines can be divided into many types, including rotary table stretch-bending machines, double-arm stretch-bending machines and various special stretch-bending machines. Double-arm stretch-bending machines can be used for bending processing of metal materials of various shapes and sizes, and are widely used. The forming mold and table of the double-arm stretch-bending machine are fixed, and the rotating arms at both ends are used to rotate the profile to gradually fit the steel mold to obtain the desired shape. Therefore, before stretching and bending, it is necessary to make the corresponding steel mold according to production needs, and then fix the steel mold on the table of the stretch-bending machine.

[0003] At present, the fixing device of the steel mold includes a plurality of independently arranged clamps and a template with a plurality of screw holes. The clamps are fixed to the template through the screw holes. After the clamps are installed, the positions are fixed, thereby stably clamping the steel mold.

[0004] Affected by the bending springback of the profile, the profile often needs to bend to a certain extent when bending to offset the rebound of the material. Therefore, when making the steel mold, the bending radius of the steel mold forming surface needs to be smaller than the bending radius required by the profile. In the actual process of making the steel mold, the bending amplitude required by the springback coefficient of the steel mold is difficult to control, and affected by the processing accuracy of the bending machine and the operating skills of the personnel, there will be a certain error between the manufactured steel mold and the required size. Therefore, it is often necessary to disassemble and assemble the steel mold for adjustment many times, which is time-consuming and labor-intensive. Summary of the invention

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a steel mold fixing device for a profile bending machine, which at least partially solves the above problems.

[0006] The technical solution adopted by the present invention is as follows: The present invention proposes a steel mold fixing device for a profile bending machine, comprising: A bottom plate is fixed on the working table of the stretch bending machine, the bottom plate supports a fixed template, and the fixed template is provided with a plurality of mounting threaded holes distributed in an array; A plurality of clamps are arranged on the fixed template along the curved path of the steel mold and are used to clamp the steel mold; Wherein, the fixed template comprises a plurality of rectangular strips sequentially distributed along the length direction of the bottom plate, the clamp is fixed on the rectangular strips, and the rectangular strips are configured to be able to slide along their own length direction; A driving component is provided on one side of the bottom plate, and the telescopic direction of the telescopic end of the driving component is parallel to the sliding direction of the rectangular strips. The driving component is configured to be able to slide along the distribution direction of the rectangular strips, so that the telescopic end of the driving component can be connected to any one of the rectangular strips and drive the rectangular strips to slide; The bottom plate is provided with two locking components, which are located at two ends of the rectangular bar in the sliding direction and are used to lock the position of the rectangular bar.

[0007] Furthermore, the clamp includes a column and a connecting screw and a clamping screw respectively fixed at both ends of the column, the connecting screw and the clamping screw are respectively provided with a clamping plate, the connecting screw is connected to the mounting threaded hole, and the clamping screw is connected to a clamping nut for clamping the clamping plate onto the steel mold.

[0008] Furthermore, a limiting rod is respectively provided on one side of the two clamping plates corresponding to each other, and a clamping gap for clamping the steel mold is formed between the limiting rod and the column.

[0009] Furthermore, a clamping joint is fixed to the top end of the compression screw.

[0010] Furthermore, the telescopic end of the driving component is provided with a connecting arm, and the connecting arm includes an extension rod and a connecting rod. One end of the extension rod is connected to the telescopic end of the driving component, and the connecting rod is connected to the other end of the extension rod. A connecting ring is rotatably connected to the connecting rod, and a connecting pin is connected to the connecting ring. The connecting pin is connected to the mounting threaded hole, so that the telescopic end of the driving component is connected to the rectangular bar.

[0011] Furthermore, the top end of the compression screw is rotatably connected to a support plate, and the support plate is connected to the connecting pin.

[0012] Furthermore, a first locking screw is provided at one end of the extension rod, and a threaded hole is provided at the other end; a second locking screw is provided at one end of the connecting rod away from the connecting ring, and the second locking screw is connected to the threaded hole.

[0013] Furthermore, the locking component includes a fixing plate fixed on the base plate, and a plurality of threaded sleeves corresponding to the rectangular strip are fixed on the fixing plate. The threaded sleeves are all connected with fixing bolts, and the tightening or loosening direction of the fixing bolts is parallel to the sliding direction of the rectangular strip.

[0014] Furthermore, a first slide rail is provided on one side of the bottom plate close to the driving component, a sliding seat is slidably connected to the first slide rail, and the driving component is fixed on the sliding seat.

[0015] Furthermore, a second slide rail fixed to the bottom plate is provided at the bottom of the rectangular strip, and the rectangular strip is slidably connected to the second slide rail.

The fixed template is set to include a plurality of rectangular bars, and the rectangular bars are set to be able to slide.

Therefore, there is no need to frequently disassemble and assemble the steel mold, saving mold adjustment time and improving production efficiency.

[0017] 2. Since the rectangular bar can be slid and adjusted, the threaded holes on the rectangular bar can be moved and adjusted synchronously accordingly. Therefore, the positions of the threaded holes can be adjusted by sliding the rectangular bar so that the threaded holes can be distributed along the curved path of the steel mold. When installing the fixture, the fixture can better fit the steel mold. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] In the description of the present invention, it should be understood that terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “top”, “bottom”, “inside” and “outside” indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0023] like Figure 1 and Figure 2 As shown, the present invention proposes a steel mold fixing device for a profile bending machine, including a base plate 1, a fixed template and a clamp 3.

[0024] The base plate 1 is fixed on the working table of the stretch bending machine, and the fixed template is installed on the base plate 1. The fixed template is provided with a plurality of mounting threaded holes 201 distributed in an array. There is no limit on the number of clamps 3. According to the length of the steel mold, a corresponding number of clamps 3 are used, and a plurality of clamps 3 are arranged on the fixed template along the curved path of the steel mold, and the clamps 3 are connected to the mounting threaded holes 201 so that the clamps 3 are fixed on the fixed template, and then the steel mold is clamped and fixed by the clamps 3.

[0025] Combination Figure 2 and Figure 3As shown, the fixed template includes a plurality of rectangular bars 2 distributed in sequence along the length direction of the base plate 1, and the distribution direction of the rectangular bars 2 is perpendicular to the length direction of the rectangular bars 2, so that the plurality of rectangular bars 2 form a flat installation surface, the installation threaded holes 201 are evenly distributed on the plurality of rectangular bars 2, and the installation threaded holes 201 are evenly distributed along the length direction of the rectangular bars 2, the clamps 3 are connected to the installation threaded holes 201, so that the clamps 3 are fixed on the rectangular bars 2, and the rectangular bars 2 are configured to be able to slide on the base plate 1 along their own length direction, and accordingly, the clamps 3 fixed on the rectangular bars 2 can move synchronously.

[0026] Furthermore, a driving component 4 is provided on one side of the bottom plate 1, and the driving component 4 is located at one end of the sliding direction of the rectangular bar 2, and the telescopic direction of the driving component 4 is parallel to the sliding direction of the rectangular bar 2, and the telescopic end of the driving component 4 is provided with a connecting arm that can be connected to the rectangular bar 2, so that the driving component 4 can drive the rectangular bar 2 to slide; The driving component 4 is configured to be able to slide along the distribution direction of the rectangular bars 2, so that the telescopic end of the driving component 4 can be connected to any one of the rectangular bars 2 and drive the rectangular bars 2 to slide.

[0027] In this way, the driving component 4 is moved to any rectangular bar 2, and then the rectangular bar 2 is connected to the telescopic end of the driving component 4 through the connecting arm. The driving component 4 applies a thrust or a pull to the rectangular bar 2, so that the rectangular bar 2 can slide. Correspondingly, the clamp 3 on the rectangular bar 2 slides synchronously, and the area corresponding to the steel mold clamped by the clamp 3 is subjected to a thrust or a pull, thereby deforming. By sliding and adjusting each rectangular bar 2, the steel mold can be shaped in a small range. Therefore, in the actual production process, if the steel mold needs to be shaped in a small range, it is not necessary to frequently disassemble and assemble the steel mold, which saves mold adjustment time and improves production efficiency. At the same time, since the rectangular bar 2 can be slidably adjusted, the mounting threaded holes 201 on the rectangular bar 2 can be moved and adjusted synchronously accordingly. Therefore, the position of the mounting threaded holes 201 can be adjusted by sliding the rectangular bar 2 so that the mounting threaded holes 201 can be distributed along the curved path of the steel mold. When the clamp 3 is installed, the clamp 3 can better fit the steel mold.

[0028] Combination Figure 1 and Figure 4 As shown, a first slide rail 11 is provided on one side of the bottom plate 1 close to the driving component 4, a sliding seat 12 is slidably connected to the first slide rail 11, the sliding direction of the sliding seat 12 is consistent with the distribution direction of the rectangular strips 2, and the driving component 4 is fixed on the sliding seat 12 by a pipe clamp.

[0029] In an optional embodiment, the driving component 4 is one of a hydraulic cylinder, an electric cylinder or a pneumatic cylinder. Preferably, the driving component 4 is a hydraulic cylinder and is connected to a hydraulic station through a pipeline. The hydraulic cylinder is driven by the hydraulic station to extend and retract. The hydraulic cylinder has no transmission gap, moves smoothly, and can accurately adjust the steel mold.

[0030] Combination Figure 8 As shown, the bottom of the rectangular bar 2 is provided with a second slide rail 21 fixed on the bottom plate 1, and the bottom surface of the rectangular bar 2 is provided with a slide groove corresponding to the shape of the second slide rail 21, and the rectangular bar 2 is slidably connected to the second slide rail 21 through the slide groove.

[0031] In an optional embodiment, the slide groove on the bottom surface of the rectangular bar 2 is a dovetail slide groove, and accordingly, the cross-sectional shape of the rectangular bar 2 is consistent with the cross-sectional shape of the slide groove. After the dovetail-shaped slide groove and the slide rail are connected, they can not only play the role of sliding guide, but also play the role of limiting, so that the rectangular bar 2 can only move along the slide rail and cannot move in other directions.

[0032] Combination Figure 1 , Figure 2 and Figure 7 As shown, two locking components are provided on the bottom plate 1 , and the locking components are located at the two ends of the rectangular bar 2 in the sliding direction, so that the position of the rectangular bar 2 can be locked by the two ends of the rectangular bar 2 .

[0033] In a specific embodiment, the locking component includes a fixing plate 5 fixed on the base plate 1, the fixing plate 5 is arranged parallel to the distribution direction of the rectangular strips 2, and threaded sleeves 51 of the same number as the rectangular strips 2 are fixed on the fixing plate 5, the threaded sleeves 51 respectively correspond to the end faces of the rectangular strips 2, and the threaded sleeves 51 are threadedly connected with fixing bolts 52, and the tightening or loosening direction of the fixing bolts 52 is parallel to the sliding direction of the rectangular strips 2.

[0034] In this way, when sliding and adjusting the position of the rectangular bar 2, the fixing bolts 52 at the positions corresponding to the two ends of the rectangular bar 2 are loosened to provide space for sliding adjustment of the rectangular bar 2. After the adjustment of the rectangular bar 2 is completed, the fixing bolts 52 at both ends are tightened until they are tightly against the two ends of the rectangular bar 2, so that the two ends of the rectangular bar 2 are locked. At this time, the rectangular bar 2 cannot slide, so that the position of the clamp 3 installed on the rectangular bar 2 is fixed.

[0035] Combination Figure 5As shown, the clamp 3 includes a column 31 and a connecting screw 32 and a clamping screw 33 respectively fixed at both ends of the column 31, and a clamping plate 34 is respectively sleeved on the connecting screw 32 and the clamping screw 33. The connecting screw 32 is threadedly connected to the mounting threaded hole 201 of the rectangular bar 2 close to the steel mold, and then the rectangular bar 2 is slid to adjust the position of the column 31 so that the column 31 is pressed against the inner wall of the steel mold, and the steel mold is placed between the two clamping plates 34. A clamping nut 36 is connected to the clamping screw 33. By tightening the clamping nut 36 downward, the clamping plate 34 clamps the steel mold. When the profile is bent along the outer side of the steel mold, the column 31 supports the steel mold to improve the stability of the steel mold.

[0036] Furthermore, the two clamping plates 34 are provided with limiting rods 35 on the surfaces corresponding to each other, and a clamping gap for clamping the steel mold is formed between the limiting rods 35 and the columns 31, and the width of the clamping gap is adapted to the thickness of the steel mold. Therefore, when clamping the steel mold, the steel mold is placed in the clamping gap formed between the limiting rods 35 and the columns 31. At this time, the inner wall of the steel mold is limited by the columns 31, and the outer wall of the steel mold is limited by the limiting rods 35 located at the upper and lower sides of the steel mold. When the driving component 4 applies a thrust or a pull to adjust the shape of the steel mold, the column 31 applies an outward deformation force to the steel mold, and the limiting rod 35 applies an inward deformation force to the steel mold, making the force deformation process of the steel mold more stable and avoiding slippage between the clamp 3 and the steel mold.

[0037] It should be noted that the two clamps 34 are respectively mounted on the connecting screw 32 and the clamping screw 33, and the two clamps 34 can rotate. Therefore, when clamping the steel mold, the two clamps 34 can be rotated and adjusted so that the limit rod 35 is located outside the steel mold and adjusted until the steel mold can be placed in the clamping gap formed between the limit rod 35 and the column 31. The position of the limit rod 35 is not affected by the rotation of the connecting screw 32.

[0038] Furthermore, a clamping joint 37 is fixed to the top of the clamping screw 33. The clamping joint 37 is a regular hexagonal prism and can be connected to the clamping joint 37 using a universal wrench on the market. Then, the column 31, the connecting screw 32 and the clamping screw 33 are rotated to tighten the connecting screw 32 into the mounting threaded hole 201.

[0039] It should be understood that the thread opening directions of the connecting screw 32 and the clamping screw 33 are consistent, so that the tightening direction of the connecting screw 32 is consistent with the tightening direction of the clamping nut 36, and when the clamping nut 36 is tightened, the connecting screw 32 is prevented from being loosened.

[0040] Combination Figure 1 , Figure 2 , Figure 4 and Figure 6As shown, the connecting arm includes an extension rod 41 and a connecting rod 42, one end of the extension rod 41 is connected to the telescopic end of the driving component 4, and the connecting rod 42 is connected to the other end of the extension rod 41. A connecting ring 421 is rotatably connected to the connecting rod 42, and a connecting pin 6 is connected to the connecting ring 421. An external thread is provided at the bottom of the connecting pin 6. The connecting pin 6 passes through the connecting ring 421 and is then threadedly connected to the mounting threaded hole 201 on the rectangular bar 2, so that the telescopic end of the driving component 4 is connected to the rectangular bar 2, and a thrust or pull is applied to the rectangular bar 2 to make the rectangular bar 2 slide.

[0041] There is no limit to the number of extension rods 41. Therefore, by adding extension rods 41, the connecting ring 421 and the connecting pin 6 can be brought close to the clamp 3, and the connecting pin 6 can be connected to the mounting threaded hole 201 closest to the clamp 3. Accordingly, the top end of the clamping screw 33 is rotatably connected to the support plate 38, and the support plate 38 can be connected to the connecting pin 6. At this time, the support plate 38 and the connecting pin 6 can play an auxiliary supporting role to prevent the clamp 3 from deforming when the driving component 4 applies thrust or tension.

[0042] It is understandable that, when the steel mold is not adjusted, a connecting pin 6 can also be set on one side of each clamp 3, and then the support plate 38 is connected to the connecting pin 6, which can improve the stability of the clamp 3 when the profile is bent.

[0043] In a specific embodiment, a hole corresponding to the connecting pin 6 is formed on the supporting plate 38 , and the connecting pin 6 passes through the hole on the supporting plate 38 and is connected to the mounting threaded hole 201 .

[0044] Combination Figure 6 As shown, a first locking screw 411 is provided at one end of the extension rod 41, and a threaded hole 412 is provided at the other end. A second locking screw 422 is provided at the end of the connecting rod 42 away from the connecting ring 421. The second locking screw 422 is connected to the threaded hole 412, so that the connecting rod 42 is fixed on the extension rod 41.

[0045] It can be understood that since the connecting ring 421 is rotatably connected to the connecting rod 42, when the connecting rod 42 is rotated and locked, the connecting ring 421 can be rotatably adjusted so that the hole of the connecting ring 421 and the mounting threaded hole 201 are in parallel with each other, which will not affect the installation of the connecting pin 6.

[0046] The working principle of the present invention is as follows: according to the length of the steel mold, a corresponding number of clamps 3 are used, and multiple clamps 3 are arranged on the fixed template along the curved path of the steel mold, and the connecting screw 32 of the clamp 3 is connected to the mounting threaded hole 201, so that the clamp 3 is fixed on the fixed template, and then the rectangular strips 2 are slid and adjusted to make the clamp 3 close to the steel mold, and then the steel mold is placed between the two clamps 34, and the column 31 is pressed against the inner wall of the steel mold, and then the clamp 34 is rotated to adjust the position of the limit rod 35, so that the steel mold can be placed in the clamping gap formed between the limit rod 35 and the column 31, and then the clamping nut 36 is rotated to make the two clamps 34 clamp the steel mold, at this time, the steel mold is fixed, and the profile can be bent along the outer side of the steel mold; Move the driving component 4 to any rectangular bar 2, then pass the connecting pin 6 through the connecting ring 421 and threadably connect it to the mounting threaded hole 201 on the rectangular bar 2, so that the telescopic end of the driving component 4 is connected to the rectangular bar 2, and then loosen all the fixing bolts 52 at both ends of the rectangular bar 2, and apply tension or thrust to the rectangular bar 2 through the driving component 4, so that the rectangular bar 2 can slide, and accordingly, the clamp 3 on the rectangular bar 2 slides synchronously, and the area corresponding to the steel mold clamped by the clamp 3 is subjected to thrust or tension, thereby deforming. After the adjustment is completed, tighten the fixing bolts 52 at both ends until they are tightly pressed against the two ends of the rectangular bar 2, so that the two ends of the rectangular bar 2 are locked. At this time, the rectangular bar 2 cannot slide, so that the position of the clamp 3 installed on the rectangular bar 2 is fixed, and each rectangular bar 2 is adjusted by sliding to achieve a small-scale shaping of the steel mold.

[0047] In summary of the above embodiments: by setting the fixed template to be composed of multiple rectangular bars 2, and the rectangular bars 2 are set to be able to slide on the bottom plate 1 along their own length direction, correspondingly, the clamps 3 fixed on the rectangular bars 2 can move synchronously, therefore, the driving component 4 is used to apply a pulling force or a thrust to the rectangular bars 2 to make the rectangular bars 2 slide, and correspondingly, the clamps 3 on the rectangular bars 2 slide synchronously, and the area corresponding to the steel mold clamped by the clamps 3 is subjected to a thrust or a pulling force, thereby causing deformation, and each rectangular bar 2 is adjusted by sliding to achieve a small-scale shaping of the steel mold. Therefore, in the actual production process, if the steel mold needs to be shaped in a small range, there is no need to frequently disassemble and assemble the steel mold, thereby saving mold adjustment time and improving production efficiency.

[0048] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0049] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.

[0050] The present invention and its embodiments are described above, and such description is not restrictive.
