Sheet metal bending machine die fixing protection device

Abstract

This utility model discloses a sheet metal bending machine mold fixing and protection device, including a lower mold and an upper mold of the bending machine. An installation mechanism is installed on both sides of the surface of the upper mold, and a moving mechanism is installed inside the installation mechanism. A protective mechanism is installed inside the moving mechanism, and limiting bolts are inserted at both ends of the moving mechanism. This utility model uses installation bolts to thread a mounting plate to the upper mold of the bending machine, allowing two sets of guide rods to be installed on both sides of the upper mold surface. This enables the installation rods to mount a protective baffle. The protective baffle provides protection and shielding during bending between the lower and upper molds. Furthermore, the sliding block along the inside of the guide rods allows for adjustment of the protective baffle, facilitating the blocking of materials of different sizes. The limiting bolts, by pressing against the surface of the guide rods, limit the movement of the sliding block.

Description

Technical Field

[0001] This utility model relates to the field of bending machine technology, and in particular to a die fixing and protection device for sheet metal bending machines. Background Technology

[0002] Sheet metal bending machines use equipped molds (general or special molds) to bend cold metal sheets into workpieces with various geometric cross-sectional shapes. They are sheet metal forming machines designed for cold-rolled sheet metal processing and are widely used in sheet metal bending processing in industries such as automobiles, aircraft manufacturing, light industry, shipbuilding, containers, elevators, and railway vehicles.

[0003] When using a sheet metal bending machine, the metal sheet is placed on the lower die, and the upper die presses down to bend the metal sheet. However, the material may crack due to shearing or punching during the bending process, which may cause material or debris to fly and injure production personnel. To address this problem, we propose a die fixing and protection device for sheet metal bending machines. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a sheet metal bending machine mold fixing and protection device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A sheet metal bending machine mold fixing and protection device includes a lower mold and an upper mold of the bending machine. The upper mold of the bending machine is equipped with an installation mechanism on both sides of its surface, and a moving mechanism is installed inside the installation mechanism. A protective mechanism is installed inside the moving mechanism. Limiting bolts are inserted into both ends of the moving mechanism, and a limiting mechanism is fixed above both ends of the moving mechanism.

[0007] Preferably, the mounting mechanism includes mounting bolts, and a mounting plate is mounted on the surface of the mold on the bending machine via the mounting bolts, and a guide rod is fixedly connected to the outer side of the mounting plate.

[0008] Preferably, the moving mechanism includes a movable slider, the guide rod has a groove inside, and the movable slider is inserted into the groove. The outer end of the movable slider is fixedly connected to a mounting rod.

[0009] Preferably, the protective mechanism includes a fixed shaft, with the fixed shaft inserted into both ends of the mounting rod, and a protective baffle fixedly connected to the end of the fixed shaft.

[0010] Preferably, the outer end of the movable slider is threaded with a limiting bolt, which is composed of a stud and a nut, and the side of the guide rod is provided with a strip-shaped through groove that matches the stud.

[0011] Preferably, the limiting mechanism includes a fixed frame, with fixed frames fixedly connected to the upper ends of both ends of the mounting rod, and the inner wall of the fixed frame is welded to one end of the return spring, the other end of the return spring is welded to the upper side of the fixed plate, and a plug-in post is fixedly connected to the lower side of the fixed plate.

[0012] Preferably, a pull rod is inserted into the outer end of the fixed frame, and the end of the pull rod is fixedly connected to the fixed plate. The insertion post is cylindrical, and the surface of the fixed shaft has two concave holes that are adapted to the insertion post.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This device connects the mounting plate to the upper die of the bending machine via mounting bolts. Two sets of guide rods can be installed on both sides of the upper die surface of the bending machine, allowing the mounting rods to install the protective baffle. The protective baffle then acts as a protective barrier when the lower die and upper die of the bending machine are bending. Furthermore, by moving the slider along the inside of the guide rod, the protective baffle can be adjusted to block materials of different sizes. The limiting bolts press against the surface of the guide rods to limit the movement of the slider.

[0015] 2. By pulling the pull rod, the fixed plate can move the plug-in column within the fixed frame. At this time, the spring force of the return spring can make the fixed plate move the plug-in column back to its original position, so that the plug-in column can be inserted into the recessed hole inside the fixed shaft, which facilitates the vertical or horizontal positioning and fixing of the protective baffle.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Reference Figure 1-4 A sheet metal bending machine mold fixing and protection device includes a lower mold 1 and an upper mold 2. The upper mold 2 is equipped with mounting mechanisms 3 on both sides of its surface, and a moving mechanism 4 is installed inside the mounting mechanism 3. A protective mechanism 5 is installed inside the moving mechanism 4. The protective mechanism 5 can conveniently provide shielding and protection. Limiting bolts 6 are inserted at both ends of the moving mechanism 4, and a limiting mechanism 7 is fixed above both ends of the moving mechanism 4.

[0028] Furthermore, refer to Figure 2 and Figure 3 It can be seen that the mounting mechanism 3 includes mounting bolts 31. The surface of the mold 2 on the bending machine is mounted with a mounting plate 32 by mounting bolts 31, and a guide rod 33 is fixedly connected to the outside of the mounting plate 32. Two guide rods are installed in the mounting plate 32 by mounting bolts 31, which can increase the installation stability of the mounting plate 32 and the guide rod 33.

[0029] Furthermore, refer to Figure 3 and Figure 4 It can be seen that the moving mechanism 4 includes a movable slider 41. The guide rod 33 has a groove inside, and the movable slider 41 is inserted in the groove. The movable slider 41 can slide along the groove through the groove inside the guide rod 33, which plays the role of guiding and adjusting the mounting rod 42. The outer end of the movable slider 41 is fixedly connected to the mounting rod 42. The mounting rod 42 has a U-shaped cross-section, which facilitates the installation of the protective mechanism 5.

[0030] Furthermore, refer to Figure 3 and Figure 4It can be seen that the protective mechanism 5 includes a fixed shaft 51. The fixed shaft 51 is inserted into both ends of the mounting rod 42, and the end of the fixed shaft 51 is fixedly connected to a protective baffle 52. The protective baffle 52 can be easily rotated inside the mounting rod 42 through the fixed shaft 51.

[0031] Furthermore, refer to Figure 3 and Figure 4 It can be seen that the outer end of the movable slider 41 is threaded with a limiting bolt 6, which is composed of a stud and a nut. The guide rod 33 has a strip-shaped through groove on its side that matches the stud. By rotating the limiting bolt 6, the limiting bolt 6 can move along the movable slider 41 and make the nut abut against the surface of the guide rod 33, thus limiting the movable slider 41 and the mounting rod 42. At the same time, through the strip-shaped through groove on the side of the guide rod 33, the movable slider 41 can drive the limiting bolt 6 to slide along the strip-shaped through groove, which facilitates the adjustment of the position of the mounting rod 42.

[0032] Furthermore, refer to Figure 3 and Figure 4 It can be seen that the limiting mechanism 7 includes a fixed frame 71. The fixed frame 71 is fixedly connected to the upper ends of both ends of the mounting rod 42. The inner wall of the fixed frame 71 is welded to one end of the return spring 72, and the other end of the return spring 72 is welded to the upper side of the fixed plate 73. Through the elastic force of the return spring 72 itself, the fixed plate 73 and the plug-in post 74 can be easily pushed to reset. The plug-in post 74 is fixedly connected to the lower side of the fixed plate 73. The fixed frame 71 can play the role of limiting and guiding the fixed plate 73.

[0033] Furthermore, refer to Figure 3 and Figure 4 It can be seen that a pull rod 75 is inserted into the outer end of the fixed frame 71, and the end of the pull rod 75 is fixedly connected to the fixed plate 73. The pull rod 75 can easily pull the fixed plate 73 and the plug-in post 74. The plug-in post 74 is cylindrical. The surface of the fixed shaft 51 has two recessed holes that are compatible with the plug-in post 74. The recessed holes on the surface of the fixed shaft 51 allow the plug-in post 74 to be inserted into the recessed holes to limit the movement of the protective baffle 52. Furthermore, the cylindrical shape of the plug-in post 74 reduces the wear of the plug-in connection.

[0034] Working principle: When this utility model is in use, when the lower die 1 of the bending machine is in use, according to the attached... Figure 1 Appendix Figure 2 Appendix Figure 3 and attached Figure 4By connecting the mounting bolts 31 through the mounting plate 32 to both sides of the upper die 2 of the bending machine, the guide rod 33 can be installed. Rotating the limiting bolt 6 allows it to move along the sliding block 41, causing it to abut against the guide rod 33 and limit the mounting rod 42. When the pulling rod 75 is pulled, it causes the fixing plate 73 and the insertion post 74 to retract into the fixing frame 71, thereby allowing the protective baffle 52 to rotate within the mounting rod 42, driving the fixing shaft 51 to rotate. When the protective baffle 52 is vertically positioned, it can be used to fold the lower die 1 and the upper die 2 of the bending machine. When bending, the protective baffle 52 is installed horizontally to facilitate the loading and unloading of materials. When the protective baffle 52 is placed vertically or horizontally, the pull rod 75 is released. The elastic force of the return spring 72 can cause the fixed plate 73 to drive the insertion post 74 to return to its original position, so that the insertion post 74 can pass through the mounting rod 42 and be inserted into the fixed shaft 51, thus limiting the protective baffle 52. At the same time, by moving the limiting bolt 6 away from the surface of the guide rod 33, the movable slider 41 can slide along the guide rod 33, which is convenient for adjusting the distance between the protective baffle 52 and the lower die 1 and the upper die 2 of the bending machine.

[0035] The above is the complete working principle of this utility model.
