Description

Technical Field

[0001] The utility model belongs to the technical field of trailer processing, and particularly relates to a steel plate bending machine. Background Art

[0002] A trailer generally refers to a freight or special-purpose vehicle without power that needs to be towed by a towing vehicle. Its structure includes multiple large metal frames and plates, such as a vehicle frame, a carriage wall plate, a support beam, etc. These components often need to be formed into specific angles and shapes according to design requirements, and at this time, a special steel plate bending machine is required.

[0003] A steel plate bending machine with the authorization announcement number of CN 220072877 U includes a workbench. On the front and back sides of the side walls on both sides of the middle of the workbench, a first chute is opened. A slider is movably installed in the inner cavity of the first chute, and a cross bar is fixedly installed between the left and right sliders; through the combined use of an elastic telescopic plate structure and an extrusion block structure, in this steel plate bending machine of the utility model, the steel plate is inserted into a first strip-shaped groove opened in the inner cavity of the front and back cross bars, and then all pull rings are manually stretched, so that the clamping blocks are moved out of the clamping holes, thereby quickly adjusting the positions of the front and back cross bars, facilitating the placement of steel plates of different lengths. At the same time, the bending angle of the steel plate can be observed at any time by using a dial, achieving the effect of effectively fixing steel plates of different lengths, widths, and thicknesses and timely observing the bending process of the steel plate, and reducing the bending error.

[0004] Although it can realize the bending operation of the steel plate, there are still some problems during the use process. The process of repositioning the bending point is relatively cumbersome, which hinders continuous and efficient multi-point bending operations and affects the overall work efficiency. In addition, when the bending angle is large, the removal of the steel plate becomes quite inconvenient, and it is even difficult to take out at some extreme angles, which undoubtedly limits the smoothness and application range of the equipment and reduces the user experience. Content of the Utility Model

[0005] In view of this, the utility model provides a steel plate bending machine, which can coordinate the work of an installation mechanism, a driving component, and a bending component. Only by simply adjusting the position of the steel plate and without repeating cumbersome operations, multi-point bending operations can be carried out continuously and efficiently. At the same time, the rapid extraction of the bent finished product is realized, greatly improving the operation smoothness, solving the problem that it is inconvenient to take out the steel plate after bending, and greatly improving the work efficiency and bending quality.

[0006] To solve the above technical problems, the present utility model provides a steel plate bending machine, which includes a mounting frame and a mounting mechanism disposed within the mounting frame. The mounting mechanism includes dovetail chutes one that are longitudinally and symmetrically disposed at the front and rear ends of the upper sides of the left and right surfaces of the mounting frame. Slide blocks are longitudinally slidably connected within the dovetail chutes one. Rotating frames are rotatably connected between two laterally adjacent slide blocks. Adjusting screws are threadedly connected within screw holes that are transversely and symmetrically disposed at the left and right ends of the upper surface of the rotating frame. Pressing plates are rotatably connected at the upper ends between two laterally adjacent adjusting screws. The pressing plates are respectively cooperatively disposed with the vertically adjacent rotating frames. A driving assembly for driving the movement of the slide blocks is further provided at the upper end of the mounting frame, and a bending assembly is further provided in the middle of the upper end of the mounting frame.

[0007] The driving assembly includes fixing blocks that are longitudinally and symmetrically disposed at the front and rear ends of the upper sides of the left and right surfaces of the mounting frame. A bidirectional lead screw is rotatably connected between two longitudinally adjacent fixing blocks. The front and rear ends of the bidirectional lead screw are respectively threadedly connected to threaded holes corresponding to the outer ends of the adjacent slide blocks on the same side; The driving assembly further includes knobs respectively disposed at the front and rear extending ends of the bidirectional lead screw.

[0008] Rotating rollers are transversely rotatably connected within openings provided in the middle of the rotating frame and the pressing plate. Two vertically adjacent rotating rollers are cooperatively disposed with each other.

[0009] The bending assembly includes dovetail chutes two that are transversely and symmetrically disposed in the middle of the upper ends of the left and right surfaces of the mounting frame. A sliding plate is vertically slidably connected between the two dovetail chutes two. A bending cutter head is fixedly installed on the lower surface of the sliding plate through a plurality of bolts. Electric telescopic rods are respectively provided within through mounting openings provided on the top wall surfaces of the dovetail chutes two. The lower ends of the telescopic ends of the two electric telescopic rods are fixedly connected to the upper surface of the sliding plate. The electric telescopic rods are electrically connected to an external single-chip microcomputer.

[0010] Guide support slide rods are symmetrically distributed at the four corners of the lower surface of the pressing plate, and slide holes corresponding to the guide support slide rods one by one are provided at the four corners of the upper surface of the rotating frame.

[0011] Longitudinally symmetrically distributed scale lines are provided on the upper sides of the front and rear ends of the left and right walls of the mounting frame. The scale lines are respectively cooperatively disposed with the adjacent slide blocks on the same side.

[0012] The beneficial effects of the above technical solutions of the present utility model are as follows:

[0013] 1. First, the relevant operators place the steel plate between the vertically arranged rotating rollers and align the position to be bent with the bending knife head. Then, the relevant operators synchronously turn the adjusting screws located on the same pressing plate. The rotation of the adjusting screws drives the pressing plate and the rotating rollers on it to move downward synchronously. When the upper rotating roller slightly touches the steel plate without affecting the movement of the steel plate, the relevant operators stop turning the adjusting screws. When the steel plate is properly placed, the relevant operators control the operation of the electric telescopic rod through an external single-chip microcomputer. The telescopic end of the electric telescopic rod moves downward to push the sliding plate and the bending knife head to move downward synchronously, thereby applying pressure to the steel plate and bending it. At this time, the natural movement of the steel plate away from the bending area will cleverly trigger the adaptive swing of the rotating frame and the supporting mechanism on the same side, and at the same time, it will smoothly transition between adjacent rotating rollers. Once a bend is completed, only the position of the steel plate needs to be simply adjusted, and there is no need to repeat cumbersome operations, so that multi-point bending operations can be carried out continuously and efficiently, greatly improving the work efficiency and bending quality, and meeting the processing requirements of steel plates of various specifications.

[0014] 2. When it is necessary to change the bending degree required for the processing of the trailer steel plate, the relevant operators only need to synchronously rotate the bidirectional screw rod. The rotation of the bidirectional screw rod drives two adjacent sliding blocks on the same side to move synchronously towards or away from each other, thereby adjusting the distance between the two rotating frames, so as to meet the diverse bending angle requirements of the steel plate.

[0015] 3. After the steel plate bending operation is completed, only need to synchronously rotate the adjusting screw located on the same pressing plate counterclockwise, so that the pressing plate can be removed, realizing the rapid extraction of the bent finished product, greatly improving the operation smoothness, and solving the problem that it is inconvenient to take out the steel plate after bending. The matching design of the guiding support slide rod and the slide hole not only provides stable guiding support for the pressing plate, but also ensures the stability and durability of the entire bending process.

[0016] 4. The scale line provides an intuitive reference for the operator, facilitating the rapid setting and reproduction of the specific sliding block position, so as to achieve the required steel plate clamping width or bending position, and improving the repeatability and accuracy of the work.

Based on the described embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present utility model.

[0023] As Figures 1-4 shown:

[0024] This embodiment provides a steel plate bending machine, which includes a mounting bracket 100 and a mounting mechanism arranged inside the mounting bracket 100. The mounting mechanism includes first dovetail chutes 200 symmetrically arranged longitudinally at the front and rear ends of the upper sides of the left and right surfaces of the mounting bracket 100 respectively. Sliding blocks 201 are longitudinally slidably connected in the first dovetail chutes 200. Rotating frames 202 are rotatably connected between two laterally adjacent sliding blocks 201. Adjusting screws 203 are threadedly connected in the screw holes symmetrically arranged horizontally at the left and right ends of the upper surface of the rotating frame 202. Pressing plates 204 are rotatably connected between the upper ends of two laterally adjacent adjusting screws 203. The pressing plates 204 are respectively arranged in cooperation with the vertically adjacent rotating frames 202. A driving assembly for driving the sliding blocks 201 to move is further provided at the upper end of the mounting bracket 100, and a bending assembly is further provided in the middle of the upper end of the mounting bracket 100; the bending assembly includes second dovetail chutes 500 symmetrically arranged horizontally at the middle parts of the upper ends of the left and right surfaces of the mounting bracket 100. A sliding plate 501 is vertically slidably connected between the two second dovetail chutes 500. A folding cutter head 502 is fixedly installed on the lower surface of the sliding plate 501 through a plurality of bolts. Electric telescopic rods 503 are arranged in the through mounting openings provided on the top wall surfaces of the second dovetail chutes 500. The lower ends of the telescopic ends of the two electric telescopic rods 503 are fixedly connected to the upper surface of the sliding plate 501. The electric telescopic rods 503 are electrically connected to an external single-chip microcomputer; Guide support slide bars 600 are symmetrically arranged at the four corners of the lower surface of the pressing plate 204, and slide holes corresponding to the guide support slide bars 600 one by one are arranged at the four corners of the upper surface of the rotating frame 202.

[0025] As Figures 1-4As shown in the figure, the driving assembly includes fixing blocks 300 symmetrically arranged longitudinally at the front and rear ends of the upper sides of the left and right surfaces of the mounting frame 100. A bidirectional lead screw 301 is rotatably connected between two longitudinally adjacent fixing blocks 300. The front and rear ends of the bidirectional lead screw 301 are respectively threadedly connected to threaded holes corresponding to the outer ends of the adjacent sliding blocks 201 on the same side. The driving assembly further includes knobs 302 respectively arranged at the front and rear extending ends of the bidirectional lead screw 301.

[0026] As Figures 1-2 As shown in the figure, rotation rollers 400 are horizontally rotatably connected in the openings provided in the middle of the rotating frame 202 and the pressing plate 204, and two vertically adjacent rotation rollers 400 are cooperatively arranged.

[0027] The working principle of a steel plate bending machine provided by the present utility model is as follows: First, relevant operators place the steel plate between the vertically arranged rotation rollers 400 and align the position to be bent with the bending knife head 502. Then, the relevant operators synchronously turn the adjusting screw 203 located on the same pressing plate 204. The rotation of the adjusting screw 203 drives the pressing plate 204 and the rotation rollers 400 thereon to move downward synchronously. When the upper rotation roller 400 slightly contacts the steel plate and does not affect the movement of the steel plate, the relevant operators stop turning the adjusting screw 203. When the steel plate is placed well, the relevant operators control the operation of the electric telescopic rod 503 through an external single-chip microcomputer. The telescopic end of the electric telescopic rod 503 moves downward to push the sliding plate 501 and the bending knife head 502 to move downward synchronously, thereby applying pressure to the steel plate and bending it. At this time, the natural movement of the steel plate away from the bending position will cleverly trigger the adaptive swing of the rotating frame 202 and the supporting mechanism on the same side, and at the same time, there is a smooth transition between adjacent rotation rollers 400. Once a bending is completed, only by simply adjusting the position of the steel plate, without repeating cumbersome operations, multi-point bending operations can be continuously and efficiently carried out, greatly improving the work efficiency and bending quality, and meeting the processing requirements of various specifications of steel plates. When it is necessary to change the bending degree required for trailer steel plate processing, the relevant operators only need to synchronously rotate the bidirectional lead screw 301. The rotation of the bidirectional lead screw 301 drives two adjacent sliding blocks 201 on the same side to move towards or away from each other synchronously, thereby adjusting the distance between the two rotating frames 202, so as to meet the diverse bending angle requirements of the steel plate. The setting of the knob 302 facilitates the manual operation of the operator. After the adjustment is completed, when the steel plate bending operation is completed, only by synchronously rotating the adjusting screw 203 located on the same pressing plate 204 counterclockwise, the pressing plate 204 can be removed, realizing the rapid extraction of the bent finished product, greatly improving the operation fluency, and solving the problem that it is inconvenient to take out the steel plate after bending. The matching design of the guiding support slide rod 600 and the slide hole not only provides stable guiding support for the pressing plate 204, but also ensures the stability and durability of the system during the entire bending process.

[0028] As Figures 1-3As shown, longitudinal symmetrically distributed scale lines 700 are provided on the upper sides of the front and rear ends of the left and right walls of the mounting bracket 100. The scale lines 700 are respectively arranged in cooperation with the adjacent sliding blocks 201 on the same side. The scale lines 700 provide an intuitive reference for the operator, facilitating the quick setting and reproduction of specific sliding block positions, thereby achieving the required steel plate clamping width or bending position, and improving the repeatability and accuracy of the work.

[0029] In addition, it should be noted that in the description of the present utility model, unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0030] The above is the preferred embodiment of the present utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the principle described in the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
