Description

Technical Field

[0001] This utility model relates to the field of bending machine technology, and in particular to an auxiliary support for a bending machine. Background Technology

[0002] With the development of industrial technology, bending machines currently used on the market can be roughly divided into two categories according to the feeding method. One type is the more advanced automatic feeding type, in which the feeding and bending of the sheet metal are completed by the bending machine's own program control, and the operator does not need to manually feed the sheet metal. The other type requires the operator to manually feed the sheet metal during bending. However, considering the issue of procurement costs, most factories still use the relatively inexpensive manual feeding bending machine.

[0003] However, when using manual feeding, the operator needs to place a temporary support frame in front of the bending machine and then place the sheet on the support frame. This way, the operator does not need to hold the sheet for a long time and can simply feed it horizontally forward. Some bending machines come with a bracket, but this type of bracket is fixed to the bending machine and its position cannot be adjusted. When the width of the sheet being bent is less than the distance between the two brackets, the bracket cannot provide support. In this case, the operator still needs to find a temporary bracket. In addition, the brackets that come with the bending machine cannot be flexibly stored.

[0004] A utility model patent with publication number CN 208245511 U and publication date of December 18, 2018, discloses a bending machine, including a frame, an upper bending die, and a lower bending die. A sheet metal clamping assembly is provided on the frame, comprising a first bracket and a second bracket, which are slidably mounted on the frame. Each of the first and second brackets is equipped with clamping parts for clamping the edge of the sheet metal and slidable towards the lower bending die. A driving assembly is provided on the frame to drive the first and second brackets to slide. After the sheet metal is installed, the operator pushes the sheet metal between the upper and lower bending dies, driving the upper bending die towards the lower bending die to complete the bending process. During the bending process, the operator's hands can hold the clamping parts of the first and second brackets without directly contacting the sheet metal. The vibration of the sheet metal during bending will not cause injury to the operator's hands, thus improving the safety of the sheet metal bending operation.

[0005] In this patent, the distance between the first and second supports is adjusted by means of gears and racks, which makes up for the problem of the non-adjustable distance mentioned above. However, the first and second supports in this patent cannot be stored after use or during transportation, which will increase the overall width of the bending machine, resulting in a large space occupation and inconvenience for transportation.

[0006] Therefore, there is an urgent need for an auxiliary support for bending machines, which can flexibly adjust the spacing of the supports according to the width of the sheet metal, while also facilitating storage and transportation and reducing space occupation. Utility Model Content

[0007] To address the aforementioned technical problems, this utility model provides an auxiliary support for a bending machine, which solves the problems of fixed support positions in current bending machines, inability to flexibly adjust the spacing according to the width of the sheet metal, and lack of storage capability, resulting in large space occupation and inconvenience during transportation.

[0008] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0009] An auxiliary support for a bending machine includes a body, a pressure arm on the body, a pressure knife on the pressure arm, a bending knife on the body below the pressure knife, and a horizontal slide rail on the body near the bending knife, with at least one slider slidably mounted on the slide rail.

[0010] A rotating sleeve is detachably installed on the slider. A rotating column is rotatably arranged inside the rotating sleeve. The axis of the rotating column is perpendicular to the length direction of the slide rail. A first support arm is horizontally provided at one end of the rotating column. An inclined brace is provided between the first support arm and the end of the rotating column away from the rotating sleeve. The inclined brace, the rotating column, and the first support arm form a right triangle.

[0011] The slider is equipped with a first braking bolt;

[0012] The rotating sleeve is equipped with a second braking bolt.

[0013] Furthermore, the first support arm has a hinge at one end away from the rotating sleeve, and the other end of the hinge is connected to a second support arm. The second support arm can rotate 180 degrees relative to the first support arm. A support plate is provided at the junction of the first support arm and the second support arm and on the opposite side of the hinge. One end of the support plate is fixedly connected to the first support arm.

[0014] Furthermore, the second support arm has sliding grooves on both sides along its length, and a slide frame is slidably mounted in the sliding grooves. A support column is welded to one side of the slide frame, and the support column is used to prevent the first support arm and the second support arm from sagging.

[0015] Furthermore, the carriage is provided with a base plate, and the base plate is provided with symmetrical locking blocks on both sides, the locking blocks slidingly engaging with the slide groove.

[0016] Furthermore, the groove passes through the second support arm and extends to one-fifth of the length of the first support arm.

[0017] Furthermore, the length of the carriage is less than one-fifth of the length of the first support arm.

[0018] Furthermore, a plurality of first rubber strips are equidistantly arranged on one side of the first support arm along its length, and a plurality of second rubber strips are equidistantly arranged on both sides of the second support arm. The first rubber strips and the second rubber strips are arranged alternately, and the maximum height of the hinge is less than the thickness of the first rubber strips and the second rubber strips.

[0019] Furthermore, a baffle is provided at one end of the second support arm.

[0020] Furthermore, the support column includes a sleeve and a telescopic rod, and the sleeve is provided with a third braking bolt.

[0021] Furthermore, the support plate is provided with a clearance groove.

[0022] In summary, the beneficial technical effects of this utility model are as follows:

[0023] (1) The relative sliding of the two first support arms is achieved by the cooperation of the slide rail and the slider, so that the spacing of the first support arms can be adjusted according to the width of the plate during use. The first brake bolt is used to fix the position of the first support arm on the slide rail. The rotating column and the rotating sleeve are used to realize the circumferential rotation of the first support arm, so that the first support arm can rotate and fit tightly against the side wall of the body during transportation. This avoids the extra increase in the width of the bending machine, reduces the space occupation, and facilitates transportation.

[0024] (2) The second support arm compensates for the length of the first support arm, which facilitates the support and bending of long plates. At the same time, the hinge enables the second support arm to be folded relative to the first support arm, which facilitates storage. Attached Figure Description

[0034] The present invention will now be described clearly and completely with reference to the embodiments.

[0035] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0036] In the description of the embodiments, unless otherwise expressly specified and limited, the terms "set," "connect," etc., should be interpreted broadly. 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 a direct connection or a connection through an intermediate medium, or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0037] See appendix Figure 1-8 The image shows an auxiliary support for a bending machine, including a body 1. A pressure arm 2 is provided on the body 1, and a pressure knife 3 is installed at one end of the pressure arm 2. At the same time, a bending knife 4 is provided on the body 1 below the pressure knife 3. A slide rail 5 is horizontally installed on the body 1 along the length direction near the bending knife 4. Two sliders 6 are slidably provided on the slide rail 5. Each slider 6 is equipped with a first braking bolt 10, which fixes the position of the slider 6 on the slide rail 5.

[0038] A rotating sleeve 7 is bolted onto the slider 6. A rotating column 8 is rotatably mounted inside the rotating sleeve 7. A first support arm 9 is horizontally welded to one end of the rotating column 8. A diagonal brace 26 is provided between the first support arm 9 and the end of the rotating column 8 away from the rotating sleeve 7. The diagonal brace 26, the rotating column 8, and the first support arm 9 form a right triangle. The diagonal brace 26 provides support for the first support arm 9. In addition, a second braking bolt 11 is provided on the rotating sleeve 7. The second braking bolt 11 can fix the position of the rotating column 8 inside the rotating sleeve 7. During bending, the two first support arms 9 can slide horizontally along the slide rail 5, thereby adjusting the distance between the two first support arms 9 according to the width of the sheet metal. At the same time, when storing, the rotating column 8 can rotate along the rotating sleeve 7, pressing the first support arms 9 tightly against the side wall of the main body 1. This avoids increasing the overall width of the bending machine during transportation, reduces the space occupied, and facilitates transportation.

[0039] Furthermore, a hinge 12 is provided at the end of the first support arm 9 away from the rotating sleeve 7, and a second support arm 13 is connected to the other end of the hinge 12. The second support arm 13 can rotate 180 degrees relative to the first support arm 9 through the hinge 12. At the same time, the lengths of the first support arm 9 and the second support arm 13 are equal. When bending normally, the second support arm 13 can be folded and stored in the first support arm 9 through the hinge 12. When bending a long plate, the second support arm 13 can be rotated and opened through the hinge 12 to compensate for the length of the first support arm 9.

[0040] Furthermore, a support plate 14 is provided at the joint of the first support arm 9 and the second support arm 13. The support plate 14 is located on the opposite side of the hinge 12, and one end of the support plate 14 is welded and fixed to the first support arm 9. The support plate 14 can provide an upward lifting effect on the second support arm 13 after it is opened.

[0041] Furthermore, the second support arm 13 has sliding grooves 15 on both sides along its length. The sliding grooves 15 pass through the second support arm 13 and extend to one-fifth of the length of the first support arm 9. The first support arm 9 and the second support arm 13 are slidably fitted with a slide frame 16 through the sliding grooves 15. The slide frame 16 has a base plate 17. The base plate 17 has symmetrically arranged locking blocks 18 on both sides. The locking blocks 18 are slidably fitted with the sliding grooves 15. A support column is vertically welded on one side of the base plate 17. The support column includes a sleeve 19 and a telescopic rod 20. The sleeve 19 is provided with a third braking bolt 21 for fixing the telescopic rod 20. When the second support arm 13 is opened, the support column is slid through the sliding grooves 15 to the front end of the second support arm 13. At this time, the support column provides upward support for the second support arm 13, preventing the second support arm 13 from sagging and losing its support function under the action of the plate.

[0042] It should be noted that, in order to facilitate the storage of the support column, the length of the slide 16 is less than the extension length of the slide groove 15 on the first support arm 9. When the second support arm 13 is folded and stored, the support column can be slid onto the first support arm 9 through the slide groove 15. This not only allows the support column to be stored, but also provides further support to the first support arm 9.

[0043] Furthermore, the first support arm 9 is provided with a plurality of first rubber strips 22 at equal intervals on the side in contact with the plate, and at the same time, a plurality of second rubber strips 23 are provided at equal intervals on both sides of the second support arm 13. The first rubber strips 22 and the second rubber strips 23 are arranged alternately. When the second support arm 13 is folded and stored on the first support arm 9, the second rubber strip 23 is located between two adjacent first rubber strips 22. At the same time, the support plate 14 is provided with a relief groove 25 at the position of the second rubber strip 23. When the second support arm 13 is opened, the second rubber strip 23 is placed in the relief groove 25.

[0044] Furthermore, in order to prevent the hinge 12 from scratching the board due to its own height, the maximum height of the hinge 12 is less than the thickness of the first rubber strip 22 and the second rubber strip 23. In this way, when the board is placed on the first support arm 9 and the second support arm 13, the board is prevented from contacting the hinge 12.

[0045] Finally, in order to prevent the slide 16 from sliding out of the slide groove 15 when the support column supports the second support arm 13, a baffle 24 is provided at the end of the second support arm 13. When the support column is disassembled, the support column can be slid to the end of the slide groove 15 located at the first support arm 9, and then the slide 16 can slide out along the slide groove 15.

[0046] When bending, the first support arm 9 and the second support arm 13 are first rotated 90 degrees along the rotating sleeve 7 by the rotating column 8. Then, the rotating column 8 is locked by the second brake bolt 11. Next, the distance between the two first support arms 9 is adjusted by sliding along the slide rail 5 according to the width of the plate and fixed by the first brake bolt 10. When it is necessary to compensate for the length of the first support arm 9, the second support arm 13 is opened by the hinge 12. Then, the support column is slid along the slide groove 15 to one end of the second support arm 13 and one end of the telescopic rod 20 is brought to the ground and fixed by the third brake bolt 21. At this time, the first support arm 9 and the second support arm 13 are in a coplanar horizontal state.

[0047] When transportation and storage are required, slide the support column into the groove 15 at one end of the first support arm 9, then retract the support column, then fold the second support arm 13 into the first support arm 9 via the hinge 12, then rotate the first support arm 9 as a whole by 90 degrees and press it against the side wall of the body 1, and finally fix the current position using the first brake bolt 10 and the second brake bolt 11.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape and principle of the present utility model should be included within the scope of protection of the present utility model.
