Description

Technical Field

[0001] This invention relates to the field of mold support trestles, and more particularly to an adaptive mold support trestle and its support method. Background Technology

[0002] In steel production, the molds used for steel production are usually supported by trestles due to their large weight. This not only increases the stability of the molds but also raises their height.

[0003] However, when using a support stool, it is often necessary to move it frequently to the ideal placement area. However, the weight of the support stool is still relatively high. Both hoisting and manual handling consume too many resources when moving the support stool. Therefore, it is usually equipped with rollers with elastic extension capacity to support the support stool, so that the support stool has the advantage of easy movement. After the mold is placed on the support stool, the mold pressure overcomes the spring force, so that the support stool is supported on the support surface, thereby completing the stable support of the mold.

[0004] Utility model patent CN204604263U discloses a movable trestle for mold repair, belonging to the field of mold repair tooling. It includes a trestle support beam, two trestle bodies, and a roller assembly. The trestle body has an "A"-shaped structure, consisting of two trestle legs and a support beam. The two ends of the trest support beam are fixedly connected to the upper ends of the two trest bodies. The roller assembly includes a guide roller and two driven rollers. However, in actual steel production, a single trestle may support different types of molds depending on the actual usage, and the weight of different types of molds varies. Given a fixed number of springs, if the total spring elasticity is low, the trestle will excessively compress the support surface after supporting a heavy mold, leading to damage to the support surface. If the total spring elasticity is high, the trestle may not be able to contact the support surface after supporting a light mold, resulting in unstable support for the mold. Therefore, this solution proposes an adaptive mold support trestle and its support method to address the above problems. Summary of the Invention

[0005] In view of this, the present invention proposes an adaptive mold support trestle and its support method. The trestle supports the mounting bracket using a first spring and a second spring. When supporting heavy molds, the dual action of the first and second springs allows the auxiliary rollers to share more of the mold weight, preventing excessive support force on the mounting bracket from damaging the external support surface. When supporting light molds, by adjusting the second spring mounting seat, the mounting seat slides along the mounting bracket without being subject to the elastic force of the second spring, relying solely on the elastic support of the first spring. This allows the mounting bracket to smoothly support itself on the external support surface, increasing the stability of supporting light molds.

[0006] The technical solution of this invention is implemented as follows: This invention provides an adaptive mold support trestle, including a mounting bracket, a support beam, a first elastic support component, a second elastic support component, an adjustment component, a mounting base, and auxiliary transfer rollers, wherein, A support beam, located at the top of the mounting bracket, is used to support the mold; The first elastic support component includes a first spring, which is used to support the mounting bracket; The second elastic support component includes a second spring, and the adjusting component is disposed on the second elastic support component.

The second mounting cylinder is fixedly connected to the first mounting cylinder; The second sliding member is slidably disposed on the second mounting cylinder, and the mounting base is fixedly connected to the second sliding member; The sliding inner plate is slidably connected inside the second sliding member, and the two ends of the second spring respectively abut against the second mounting cylinder and the sliding inner plate. The adjusting component is used to adjust the sliding inner plate to disengage from the second sliding member.

[0009] Based on the above technical solutions, preferably, the regulating component includes a regulating screw and a regulating slide, wherein, The top of the second mounting cylinder is provided with a threaded hole, and the adjusting screw is threadedly connected to the threaded hole; An adjusting slide bar is disposed on the inner sliding plate and is slidably connected to the adjusting screw.

[0010] Based on the above technical solutions, preferably, the system also includes an assembly insert, and the control component further includes a handwheel. The assembly insert is a square insert, which is located on top of the regulating screw; The handwheel has an assembly socket for inserting the assembly block, and the shape of the assembly socket is adapted to the shape of the assembly block.

[0011] Based on the above technical solutions, preferably, the number of auxiliary transfer rollers is four, and each of the mounting bases is provided with a first elastic support component and a second elastic support component.

[0012] Based on the above technical solutions, preferably, the first elastic support component further includes a connecting shaft, wherein... The top of the first mounting cylinder has a sliding joint hole, and the connecting shaft passes through the sliding joint hole and is fixedly connected to the first sliding member. The first spring is sleeved on the circumference of the connecting shaft and is fixedly connected to the first sliding member and the first mounting cylinder.

[0013] Based on the above technical solutions, a preferred embodiment also includes an assembly rack, wherein... The mounting bracket includes a horizontal beam and a vertical beam, the horizontal beam and the vertical beam are connected perpendicularly to each other, the vertical beam is fixedly connected to the supporting beam, and the horizontal beam is located at the end of the vertical beam away from the supporting beam; The assembly frame is an L-shaped frame, which is fixedly connected to the end of the crossbeam, and the first mounting cylinder is fixedly connected to the assembly frame.

[0014] Based on the above technical solutions, preferably, the system also includes a first reinforcing frame, a second reinforcing frame, and a third reinforcing frame, wherein, There are two vertical beams, and the two vertical beams are respectively fixedly connected to both ends of the supporting beam; The first reinforcing frame is inclined and fixedly connected to the crossbeam and the vertical beam; The second reinforcing frame is fixedly connected to the two vertical beams; The third reinforcing frame is inclined and fixedly connected to the vertical beam and the supporting beam.

[0015] This invention also proposes a support method for an adaptive mold support trestle, which, using the aforementioned adaptive mold support trestle, further includes the following steps: S1. The movement of the mounting bracket is adjusted by the auxiliary rollers to complete the movement of the trestle; S2. When it is necessary to support the low-weight mold, insert the handwheel into the assembly block and turn the handwheel. At this time, the handwheel drives the adjusting screw to rotate through the assembly block. The adjusting screw moves to the top and drives the adjusting slide to the top. The adjusting slide drives the sliding inner plate to slide to the top and compresses the second spring. S3. Repeat step S2 to move each control screw upwards to the same position; S4. Place the low-weight mold on top of the support beam. At this time, the first spring is compressed and applies force to the mounting base, and the crossbeam is supported on the external support surface.

[0016] The adaptive mold support saddle and its support method of the present invention have the following advantages over the prior art: (1) When supporting a low-weight mold, the second spring is disengaged from the mounting seat by adjusting the control component, and the low-weight mold is then placed on the support beam. At this time, the first spring is compressed by the mounting seat, and the mounting bracket slides down to support the support surface, thus completing the support treatment for the high-weight mold. This design allows the trestle of this application to support the high-weight mold. Due to the dual action of the first and second springs, the auxiliary transfer roller can share more of the mold weight during use, thereby preventing the mounting bracket from being subjected to excessive support force and damaging the external support surface. When supporting a low-weight mold, by adjusting the second spring mounting seat, the mounting seat can slide along the mounting bracket without being subjected to the elastic force of the second spring. Under the elastic support of the first spring, the mounting bracket can be smoothly supported on the external support surface, thereby increasing the support stability for the low-weight mold.

[0017] (2) By opening an assembly socket on the handwheel, the handwheel is in a detached state during actual use and is not connected to the assembly socket, preventing the adjusting screw from rotating unexpectedly due to external force. When it is necessary to adjust each adjusting screw to slide to the top, the handwheel only needs to be selectively inserted into each assembly socket. Since the assembly socket is a square socket, the handwheel can be adjusted to rotate the adjusting screw through the assembly socket, increasing the convenience of adjusting the adjusting screw. Because the trestle of this application does not require disassembly of the first and second springs when supporting high-weight or low-weight molds, the convenience of using the trestle is increased.

Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0021] like Figures 1-5 As shown, the adaptive mold support trestle of the present invention includes a mounting bracket 1, a support beam 2, a first elastic support component 3, a second elastic support component 4, an adjustment component 5, a mounting base 61, and an auxiliary transfer roller 62. The support beam 2 is disposed on the top of the mounting bracket 1 to support the mold. The first elastic support component 3 includes a first spring 33, which supports the mounting bracket 1. The second elastic support component 4 includes a second spring 44. The adjustment component 5 is disposed on the second elastic support component 4 and is used to adjust the second spring 44 to selectively support the mounting bracket 1. The mounting base 61 is slidably disposed relative to the mounting bracket 1, and both the first spring 33 and the second spring 44 are located on the top of the mounting base 61 and press against the mounting base 61. The auxiliary transfer roller 62 is rotatably disposed at the bottom of the mounting base 61 to support the mounting base 61.

[0022] In specific implementation, the auxiliary roller 62 supports the mounting base 61, the mounting base 61 supports the first spring 33 and the second spring 44, both of which are used to support the mounting bracket 1. The mounting bracket 1 can be selectively supported on the external support surface to support the supporting beam 2.

[0023] In specific implementation, when both the first spring 33 and the second spring 44 need to press against the top of the mounting base 61 and apply force to the mounting bracket 1 so that the mounting bracket 1 is disengaged from the support surface, the treadmill of this application can be moved by adjusting the auxiliary roller 62.

[0024] When it is necessary to support a heavy mold, the heavy mold is placed directly on the support beam 2. At this time, the first spring 33 and the second spring 44 both exert force on the mounting bracket 1, and the mounting bracket 1 slides down to support the support surface, thus completing the support treatment for the heavy mold.

[0025] When it is necessary to support a low-weight mold, the second spring 44 is disengaged from the mounting base 61 by adjusting component 5, and then the low-weight mold is placed on the support beam 2. At this time, the first spring 33 is compressed by the mounting base 61, and the mounting bracket 1 slides down to support the support surface, thus completing the support treatment for the low-weight mold.

[0026] This design allows the auxiliary roller 62 to bear more of the mold weight when supporting heavy molds due to the combined action of the first spring 33 and the second spring 44, thus preventing excessive support force on the mounting bracket 1 from damaging the external support surface. When supporting light molds, by adjusting the mounting seat 61 of the second spring 44, the mounting seat 61 can slide along the mounting bracket 1 without being subject to the elastic force of the second spring 44, and only under the elastic support of the first spring 33, allowing the mounting bracket 1 to be smoothly supported on the external support surface, thereby increasing the stability of supporting light molds.

[0027] In a preferred embodiment, the first elastic support component 3 further includes a first mounting cylinder 31 and a first sliding member 32, wherein the first mounting cylinder 31 is fixedly connected to the mounting bracket 1; the first sliding member 32 is slidably disposed on the first mounting cylinder 31, the mounting base 61 is fixedly connected to the first sliding member 32, and the first spring 33 is disposed between the first sliding member 32 and the first mounting cylinder 31 for resetting the sliding position of the first sliding member 32.

[0028] Specifically, when the supporting beam 2 supports the mold, the first sliding member 32 slides along the first mounting cylinder 31, thereby compressing the first spring 33.

[0029] In a preferred embodiment, the second elastic support component 4 further includes a second mounting cylinder 41, a second sliding member 42, and a sliding inner plate 43. The second mounting cylinder 41 is fixedly connected to the first mounting cylinder 31. The second sliding member 42 is slidably disposed on the second mounting cylinder 41, and the mounting base 61 is fixedly connected to the second sliding member 42. The sliding inner plate 43 is slidably connected inside the second sliding member 42, and the two ends of the second spring 44 respectively abut against the second mounting cylinder 41 and the sliding inner plate 43. The adjusting component 5 is used to adjust the sliding inner plate 43 to disengage from the second sliding member 42.

[0030] Specifically, when the supporting beam 2 supports the heavy mold, the second sliding member 42 slides along the second mounting cylinder 41 and pushes the inner sliding plate 43 to slide upward. The inner sliding plate 43 squeezes the second spring 44, thereby compressing the second spring 44 and supporting the mounting bracket 1.

[0031] Specifically, when the supporting beam 2 supports the low-weight mold, the adjusting component 5 adjusts the sliding inner plate 43 to slide along the second sliding member 42 to the top, thereby compressing the second spring 44 and no longer pressing against the mounting base 61. At this time, the second spring 44 cannot support the mounting bracket 1.

[0032] It should be noted that both the first sliding member 32 and the second sliding member 42 are cylindrical parts, which are inserted into the interior of the first mounting cylinder 31 and the second mounting cylinder 41 respectively for sliding connection.

[0033] In a preferred embodiment, the control component 5 includes a control screw 51 and a control slide rod 52. The top of the second mounting cylinder 41 is provided with a threaded hole 411, and the control screw 51 is threadedly connected to the threaded hole 411. The control slide rod 52 is disposed on the sliding inner plate 43 and is slidably connected to the control screw 51.

[0034] In practice, when the second sliding member 42 slides, the second sliding member 42 drives the inner sliding plate 43 to slide, and the inner sliding plate 43 drives the adjusting slide rod 52 to slide, thereby completing the compression of the second spring 44.

[0035] Specifically, when adjusting the sliding inner plate 43 to slide upward relative to the second sliding member 42, the adjusting screw 51 is rotated. At this time, the adjusting screw 51 moves upward under the action of the threaded connection, and drives the adjusting slide rod 52 to move upward. The adjusting slide rod 52 drives the sliding inner plate 43 to move upward, thereby completing the sliding adjustment of the sliding inner plate 43.

[0036] In a preferred embodiment, the assembly plug 7 is also included, and the control component 5 also includes a handwheel 53. The assembly plug 7 is a square plug and is disposed on the top of the control screw 51. The handwheel 53 has an assembly socket 531 for the assembly plug 7 to be inserted, and the shape of the assembly socket 531 is adapted to the shape of the assembly plug 7.

[0037] In practice, the handwheel 53 is detached and not connected to the mounting block 7 to prevent the adjusting screw 51 from rotating unexpectedly due to external force. When it is necessary to adjust the sliding of each adjusting screw 51 to the top, the handwheel 53 only needs to be selectively inserted into each mounting block 7. Since the mounting block 7 is a square block, the handwheel 53 can be adjusted to rotate the adjusting screw 51 through the mounting block 7, which increases the convenience of adjusting the adjusting screw 51.

[0038] Because the trestle of this application does not require disassembly of the first spring 33 and the second spring 44 when supporting high-weight or low-weight molds, the trestle is more convenient to use.

[0039] In a preferred embodiment, the number of auxiliary rollers 62 is four, and each mounting base 61 is provided with a first elastic support member 3 and a second elastic support member 4.

[0040] It also includes an assembly frame 8, wherein the mounting bracket 1 includes a horizontal beam 11 and a vertical beam 12, the horizontal beam 11 and the vertical beam 12 are connected perpendicularly to each other, the vertical beam 12 is fixedly connected to the support beam 2, and the horizontal beam 11 is located at the end of the vertical beam 12 away from the support beam 2; the assembly frame 8 is an L-shaped frame, the assembly frame 8 is fixedly connected to the end of the horizontal beam 11, and the first mounting cylinder 31 is fixedly connected to the assembly frame 8.

[0041] In a preferred embodiment, the first elastic support component 3 further includes a connecting shaft 34, wherein the top of the first mounting cylinder 31 is provided with a sliding hole 311, and the connecting shaft 34 passes through the sliding hole 311 and is fixedly connected to the first sliding member 32. The first spring 33 is sleeved on the periphery of the connecting shaft 34 and is fixedly connected to the first sliding member 32 and the first mounting cylinder 31.

[0042] This design allows the first spring 33 to deform along the connecting shaft 34 when it is compressed, thereby increasing the stability of the extension and retraction of the first spring 33.

[0043] In a preferred embodiment, the system further includes a first reinforcing frame 91, a second reinforcing frame 92, and a third reinforcing frame 93, wherein there are two vertical beams 12, and the two vertical beams 12 are respectively fixedly connected to both ends of the supporting beam 2; the first reinforcing frame 91 is inclined and is fixedly connected to the horizontal beam 11 and the vertical beams 12; the second reinforcing frame 92 is fixedly connected to the two vertical beams 12; and the third reinforcing frame 93 is inclined and is fixedly connected to the vertical beams 12 and the supporting beam 2.

[0044] This design increases the overall structural strength of the mounting bracket 1 through the first reinforcing frame 91 and the second reinforcing frame 92, and enhances the support effect of the mounting bracket 1 on the supporting beam 2 through the third reinforcing frame 93.

[0045] This invention also proposes a support method for an adaptive mold support trestle, which, using the aforementioned adaptive mold support trestle, further includes the following steps: Step 1: Adjust the movement of the mounting bracket 1 using the auxiliary roller 62 to complete the movement of the trestle; Step 2: When it is necessary to support the low weight mold, insert the handwheel 53 into the assembly block 7 and rotate the handwheel 53. At this time, the handwheel 53 drives the adjusting screw 51 to rotate through the assembly block 7. The adjusting screw 51 moves to the top and drives the adjusting slide rod 52 to the top. The adjusting slide rod 52 drives the sliding inner plate 43 to slide to the top and compresses the second spring 44. Step 3: Repeat step 2 until each adjusting screw 51 moves upward to the same position; Step 4: Place the lightweight mold on top of the support beam 2. At this time, the first spring 33 is compressed and applies force to the mounting base 61, and the crossbeam 11 is supported on the external support surface.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
