Description

Technical Field

[0001] This utility model relates to the field of hydraulic shearing machine technology, and in particular to a guide material support mechanism for a hydraulic shearing machine. Background Technology

[0002] The main function of the guiding and supporting mechanism is to support and guide the sheet metal to be sheared, keeping it stable during the shearing process and preventing deviation or skewing when the sheet metal is fed into the shearing area. This helps improve shearing accuracy and safety. In a hydraulic shearing machine, the guiding and supporting mechanism works closely with the hydraulic transmission system during the shearing process. When the sheet metal is fed into the shearing area, the guide rollers and the supporting plate work together to ensure that the sheet metal moves steadily along a predetermined path to achieve the best shearing effect.

[0003] When using the existing guiding material feeding mechanism, if the overall length of the steel plate is large, the steel plate will put a lot of pressure on the operator's hands, and the feeding process is prone to jamming, which will affect the forming quality of the product.

[0004] An existing patent (publication number: CN219274641U) discloses a shearing machine bracket, which includes a support frame, guide rollers, and an assembly plate. The guide rollers are equidistantly rotatably disposed inside the support frame. The assembly plate is welded to the end face of the support frame, and the surface of the assembly plate has assembly holes. Limiting components are symmetrically installed on the upper surface of the support frame. The limiting components include an assembly seat, a telescopic connecting rod, a limiting frame, and limiting rollers. The steel plate is attached to the surface of the guide rollers of the support frame at its bottom. When the steel plate is pushed in a directional manner, the two sides of the steel plate are limited and guided by the limiting rollers, maintaining the smooth movement of the steel plate and improving the stability of the feeding.

[0005] To address the aforementioned issues, existing patents propose solutions where the bottom of a steel plate is attached to the surface of the guide rollers on the support frame. When the steel plate is pushed in a directional manner, the two sides of the steel plate are limited and guided by the limiting rollers, thus maintaining the stable movement of the steel plate. However, since a long steel plate cannot be completely placed on the bracket at once, this causes the center of gravity of the steel plate to shift, which in turn causes the steel plate on the bracket to tilt. Once the steel plate tilts, the limiting rollers on both sides of the steel plate cannot effectively perform their guiding function. Summary of the Invention

[0006] The purpose of this utility model is to provide a guide and material support mechanism for a hydraulic shearing machine, which can guide and limit the steel plate. With the cooperation of the connecting rod and the tension spring, the tension spring pulls the fixed block to move vertically, thereby driving the limiting ball to contact the upper surface of the steel plate and pressing the steel plate. This can effectively reduce the situation where the steel plate warps due to the shift of the center of gravity, thus solving the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a guide and material-supporting mechanism for a hydraulic shearing machine, comprising a fixed plate, wherein the upper end of the fixed plate is provided with a material-supporting mechanism for supporting steel plates, both ends of the fixed plate are provided with limiting mechanisms for limiting the steel plates, and one side of the limiting mechanism is provided with a guide mechanism for guiding the steel plates.

[0008] The limiting mechanism includes two mounting plates, each fixed to both ends of a fixed plate. Each mounting plate has a mounting tube on one side, and one end of the mounting tube is telescopically connected to a movable rod.

[0009] The guiding mechanism includes a guide member, which is fixed to the end of the movable rod. Several guide rollers are installed inside the guide member. The outer surface of the guide rollers is covered with a protective rubber sleeve. Both ends of the guide rollers are fitted with fixed bearings embedded in the guide member.

[0010] Preferably, a stepper motor that is fixedly connected to one end of the guide roller is fixed to the upper surface of the guide member by screws.

[0011] Preferably, three limiting balls are installed on one side of the guide member, and a connecting rod that passes through the upper end of the guide member is fixed on the upper surface of the three limiting balls.

[0012] Preferably, a tension spring is fitted on the outer surface of the connecting rod, and a fixing block that is fixedly connected to the connecting rod is abutted against the upper surface of the tension spring.

[0013] Preferably, an adjusting electric cylinder that is fixedly connected to the mounting tube is bolted to the other side of the mounting plate, and a compression spring that is abutted and connected to the movable rod is installed inside the mounting tube.

[0014] Preferably, the material support mechanism includes two material support components, both of which are mounted on the upper end of the fixed plate, and both of the material support components are fitted with fixing bolts that are threadedly connected to the fixed plate on their upper surfaces.

[0015] Preferably, each of the two material support components is equipped with an mounting component at its upper end, and the inner wall of the mounting component is equipped with a fixing screw that is threadedly connected to the material support component, and the interior of the mounting component is equipped with guide balls.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. The set limiting mechanism can guide and limit the steel plate. With the cooperation of the connecting rod and the tension spring, the tension spring pulls the fixed block to move vertically, thereby driving the limiting ball to contact the upper surface of the steel plate and pressing the steel plate.

[0018] 2. The material support mechanism can support the steel plate, and the adjusting electric cylinder on the mounting plate can drive the mounting tube to move horizontally, thereby driving the two guide members to move closer to each other, so that the two guide members and the two sides of the steel plate come into contact.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides a technical solution:

[0028] Please see Figures 1 to 4A guide and material-supporting mechanism for a hydraulic shearing machine includes a fixed plate 1. The upper end of the fixed plate 1 is provided with a material-supporting mechanism for supporting steel plates. Both ends of the fixed plate 1 are provided with limiting mechanisms for limiting the steel plates. One side of the limiting mechanism is provided with a guide mechanism for guiding the steel plates.

[0029] The limiting mechanism includes a mounting plate 3, and there are two mounting plates 3. Both mounting plates 3 are fixed to both ends of the fixed plate 1. Each of the two mounting plates 3 has a mounting tube 32 on one side, and a movable rod 34 is telescopically connected to one end of the mounting tube 32.

[0030] The guiding mechanism includes a guide member 4, which is fixed to the end of the movable rod 34. Several guide rollers 41 are installed inside the guide member 4. The outer surface of the guide rollers 41 is covered with a protective rubber sleeve 42. Both ends of the guide rollers 41 are fitted with fixed bearings 43 embedded in the guide member 4. The upper surface of the guide member 4 is fixed with a stepper motor 44 that is fixedly connected to one end of the guide rollers 41 by screws. Three limiting balls 45 are installed on one side of the guide member 4. The upper surface of the three limiting balls 45 is fixed with a connecting rod 46 that passes through the upper end of the guide member 4. The outer surface of the connecting rod 46 is covered with a tension spring 47. The upper surface of the tension spring 47 abuts against a fixing block 48 that is fixedly connected to the connecting rod 46.

[0031] By adopting the above technical solution, before using the guide material support mechanism of the hydraulic shearing machine, the fixing plate 1 is first fixed to the feed port of the hydraulic shearing machine. Several guide rollers 41 inside the guide component 4 contact the side wall of the steel plate, thereby guiding and limiting the steel plate. The protective rubber sleeve 42 set on the guide roller 41 can play a protective role, thereby reducing the damage caused by the guide roller 41 to the side wall of the steel plate. The fixed bearing 43 set can ensure the normal rotation of the guide roller 41. The stepper motor 44 can drive one guide roller 41 to rotate. Due to the friction between the guide roller 41 and the side wall of the steel plate, the steel plate can be driven to be conveyed. The limiting ball 45 set on the guide component 4, under the cooperation of the connecting rod 46 and the tension spring 47, the tension spring 47 pulls the fixing block 48 to move vertically, thereby driving the limiting ball 45 to contact the upper surface of the steel plate and press the steel plate. This can effectively reduce the situation where the steel plate tilts due to the shift of the center of gravity.

[0032] Specifically, such as Figure 1 and Figure 4As shown, an adjusting electric cylinder 31, which is fixedly connected to the mounting tube 32, is fixed on the other side of the mounting plate 3 by bolts. A compression spring 33, which is abutted and connected to the movable rod 34, is installed inside the mounting tube 32. The material support mechanism includes a material support component 2. There are two material support components 2. Both material support components 2 are installed on the upper end of the fixed plate 1. The upper surface of both material support components 2 is equipped with a fixing bolt 5 that is threadedly connected to the fixed plate 1. An installation component 21 is installed on the upper end of both material support components 2. A fixing screw 22 that is threadedly connected to the material support component 2 is installed on the inner wall of the installation component 21. A guide ball 23 is installed inside the installation component 21.

[0033] By adopting the above technical solution, the steel plate to be processed is placed on the support member 2. The guide ball bearing 23 on the mounting member 21 can support the steel plate. At the same time, the adjusting electric cylinder 31 on the mounting plate 3 can drive the mounting tube 32 to move horizontally, thereby driving the two guide members 4 to move closer to each other, so that the two guide members 4 contact the two sides of the steel plate. After the guide members 4 contact one side of the steel plate, with the cooperation of the movable rod 34, the compression spring 33 in the mounting tube 32 can be pushed to compress. After the compression spring 33 is compressed, it generates tension, thereby pushing the guide member 4 to better contact one side of the steel plate. By unscrewing the fixing bolt 5, the support member 2 can be disassembled. By unscrewing the fixing screw 22, the mounting member 21 can be replaced separately, which is convenient for use.

[0034] Working principle: The adjusting electric cylinder 31 on the mounting plate 3 drives the mounting tube 32 to move horizontally, and the two guide members 4 move closer to each other, so that the two guide members 4 contact the two sides of the steel plate. After the guide members 4 contact one side of the steel plate, they push the compression spring 33 in the mounting tube 32 to compress, so that the compression spring 33 generates tension after being compressed, thereby pushing the guide members 4 to contact the side of the steel plate better. Several guide rollers 41 in the guide members 4 contact the side wall of the steel plate, thereby guiding and limiting the steel plate. The stepper motor 44 can drive one guide roller 41 to rotate. Due to the friction between the guide roller 41 and the side wall of the steel plate, the steel plate can be driven to be conveyed. The limiting ball 45 set on the guide member 4, with the cooperation of the connecting rod 46 and the tension spring 47, pulls the fixing block 48 to move vertically, thereby driving the limiting ball 45 to contact the upper surface of the steel plate and press the steel plate.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
