Description

Technical Field

[0001] This utility model relates to the technical field of aluminum alloy bending machines, specifically to an aluminum alloy bending machine. Background Technology

[0002] A bending machine uses a set of molds (general or special molds) to bend cold metal sheets into workpieces with various geometric cross-sectional shapes. It is a sheet metal forming machine designed for cold-rolled sheet metal processing and is widely used in sheet metal bending processing in industries such as automobiles, aircraft manufacturing, light industry, shipbuilding, containers, elevators, and railway vehicles.

[0003] Existing aluminum alloy bending machines can only perform bending operations on a single shape. When it is necessary to adjust the bending angle, different bending blocks need to be replaced for extrusion bending, which is very inconvenient. Therefore, an aluminum alloy bending machine is proposed to solve the above-mentioned problems. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides an aluminum alloy bending machine with advantages such as ease of use. It solves the problem that existing aluminum alloy bending machines can only perform bending operations on a single shape, and when it is necessary to adjust the bending angle, different bending blocks are usually required for extrusion bending, which is very inconvenient to use.

[0006] (II) Technical Solution

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: an aluminum alloy bending machine includes a base, a translation mechanism is provided inside the base, two right-angle molds are connected to the outside of the translation mechanism and are slidably connected to the base, an arc groove is opened on the top of the base, and a bending head is also provided above the base.

[0008] The right-angle mold includes modules, two of which are symmetrically distributed from left to right. The opposite side of the two modules is inclined, and the inclined surfaces of the two modules can form a 90-degree angle. The bottom of each of the two modules is fixedly connected to a slide rail, and the two slide rails are slidably connected to the inside of the base. The bottom of each slide rail is fixedly connected to a translation mechanism.

[0009] The bending head includes a punch, the top of which is fixedly connected to a hydraulic device. The bottom of the punch is arc-shaped, and the radius of the arc at the bottom of the punch matches the radius of the arc groove. The left and right sides of the punch are inclined at an angle of 90 degrees. A right-angled pressure block extending to the bottom of the punch is slidably connected inside the punch. The bottom of the right-angled pressure block is right-angled and matches the module. A fixing block slidably connected to the top of the right-angled pressure block is fixedly connected to the inside of the punch. Two fixing holes are provided on both the front and rear sides of the fixing block and are symmetrically distributed vertically. Two through holes are provided inside the fixing block and are symmetrically distributed vertically. The two through holes are respectively matched with the four fixing holes. A removable pin is inserted between the through holes and the two fixing holes on the same horizontal plane.

[0010] The beneficial effects of this utility model are: when it is necessary to bend aluminum alloy into a right angle, the two modules are put together by the translation mechanism, and the right angle pressure block is fixed by the connection of the pin with the through hole and the fixing hole after the right angle pressure block is released from the punch. The aluminum alloy plate placed on the surface of the two modules can be bent into a right angle by pressing down the hydraulic equipment.

[0011] When it is necessary to bend into an arc shape, the two modules are separated by a translation mechanism. After the right-angle pressure block is taken into the punch, it is fixed by the connection of the pin with the through hole and the fixing hole. The aluminum alloy plate placed on the surface of the two modules is pressed down by the hydraulic equipment and squeezed into the arc groove by the arc surface of the bottom of the punch, so that it can be bent into an arc groove. This way, the bending of right angle or arc edge can be completed without changing the mold.

[0012] This aluminum alloy bending machine has the advantage of being easy to use.

[0013] Based on the above technical solution, the present invention can be further improved as follows.

[0014] Furthermore, the bottom of the pedestal is fixedly connected to two fixing plates that are symmetrically distributed from left to right, and both fixing plates are arranged in an L-shape.

[0015] The advantage of adopting the above-mentioned further solution is that the fixing plate is used to fix the base to the external workbench.

[0016] Furthermore, a centrally located support block is fixedly connected to the bottom of the pedestal. The support block is T-shaped, and threaded connection holes for assembly are provided at the bottom of both the fixed plates and the support block.

[0017] The beneficial effect of adopting the above-mentioned further solution is that the support block is used to support the pressure part at the bottom of the pedestal, so as to prevent the pedestal from deforming during the bending of the aluminum alloy.

[0018] Furthermore, the translation mechanism includes a lead screw, which is rotatably connected to the inside of the base. Two threaded rings, symmetrically distributed on the left and right sides, are threaded to the outer side of the lead screw. The two threaded rings are respectively fixedly connected to the bottom of two slide rails. One end of the lead screw extends to the outer side of the base, and an adjustment disc is fixedly connected to the end of the lead screw extending to the outer side of the base.

[0019] The beneficial effect of adopting the above-mentioned further solution is that the thread has self-locking properties, which can fix the two modules to any position by adjusting them to any position.

[0020] Furthermore, each of the two modules has two mold connection holes on its top, which are symmetrically distributed from left to right. The four mold connection holes are arranged in a rectangular array and are used to connect irregular molds.

[0021] The beneficial effect of adopting the above-mentioned further solution is that the mold connection hole can move with the movement of the module, allowing it to bend into other shapes using an external mold, except for right-angle bends and arc-angle bends.

[0022] Furthermore, both slide rails are integrally cast and are T-shaped. The base has grooves inside that are adapted to the two slide rails. The furthest distance between the two modules is equal to the left and right spacing of the arc groove.

[0023] The beneficial effect of adopting the above-mentioned further solution is that the farthest distance between the two modules is equal to the left and right distance of the arc groove, which enables the two modules to bend assisted by their inclined surfaces when making arc-shaped bends.

[0029] 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.

[0030] In the embodiments, by Figure 1-4 The present invention provides an aluminum alloy bending machine, comprising a base 1, a translation mechanism 2 inside the base 1, two right-angle molds 3 connected to the outside of the translation mechanism 2 and slidably connected to the base 1, an arc groove 4 on the top of the base 1, and a bending head 5 above the base 1.

[0031] The right-angle mold 3 includes modules 301. The two modules 301 are symmetrically distributed from left to right. The opposite side of the two modules 301 is inclined and the inclined surfaces of the two modules 301 can form a 90-degree angle. The bottom of each module 301 is fixedly connected to a slide rail 302. The two slide rails 302 are slidably connected to the inside of the base 1. The bottom of each slide rail 302 is fixedly connected to the translation mechanism 2.

[0032] The bending head 5 includes a punch 501, with a hydraulic device 502 fixedly connected to the top of the punch 501. The bottom of the punch 501 is arc-shaped, and the radius of the arc at the bottom of the punch 501 matches the radius of the arc groove 4. The left and right sides of the punch 501 are inclined at an angle of 90 degrees. A right-angle pressure block 507, extending from its bottom to below the punch 501, is slidably connected inside the punch 501. The bottom of the right-angle pressure block 507 is set at a right angle and is adapted to the module 301. The top of the corner block 507 is fixedly connected to a fixing block 503 that is slidably connected to the inside of the punch 501. The fixing block 503 has two fixing holes 504 on both the front and rear sides, which are symmetrically distributed vertically. The fixing block 503 has two through holes 505 inside, which are symmetrically distributed vertically. The two through holes 505 are respectively adapted to the four fixing holes 504. The same pluggable pin 506 is inserted between the through hole 505 and the two fixing holes 504 on the same horizontal plane.

[0033] The bottom of the base 1 is fixedly connected to two fixing plates 6 that are symmetrically distributed from left to right, and both fixing plates 6 are L-shaped.

[0034] The fixing plate 6 is used to fix the base 1 to the external workbench;

[0035] The bottom of the base 1 is fixedly connected to a support block 7 that is centrally positioned. The support block 7 is T-shaped. Both the bottom of the two fixing plates 6 and the support block 7 are provided with threaded connection holes 8 for assembly.

[0036] The support block 7 is used to support the pressure-bearing part at the bottom of the base 1 to prevent the base 1 from deforming during the bending of the aluminum alloy.

[0037] The translation mechanism 2 includes a lead screw 201, which is rotatably connected to the inside of the base 1. Two helical rings 202 are threadedly connected to the outside of the lead screw 201 and are symmetrically distributed on the left and right. The two helical rings 202 are fixedly connected to the bottom of the two slide rails 302 respectively. One end of the lead screw 201 extends to the outside of the base 1, and an adjustment plate 203 is fixedly connected to the end of the lead screw 201 extending to the outside of the base 1.

[0038] The threaded connections between the lead screw 201 and the two screw rings 202 have opposite thread directions;

[0039] The thread has a self-locking property, which allows the two modules 301 to be adjusted to any position and then fixed by the self-locking property of the thread;

[0040] The top of each of the two modules 301 has two mold connection holes 9 that are symmetrically distributed from left to right. The four mold connection holes 9 are arranged in a rectangular array and are used to connect irregular molds.

[0041] The mold connection hole 9 can move with the movement of module 301, allowing it to bend into other shapes using an external mold, except for right-angle bends and arc-angle bends;

[0042] Both slide rails 302 are integrally cast and are T-shaped. The base 1 has a groove 10 inside that matches the two slide rails 302. The furthest distance between the two modules 301 is equal to the left and right distance of the arc groove 4.

[0043] The furthest distance between the two modules 301 is equal to the left and right spacing of the arc groove 4, which allows for auxiliary bending through the inclined surfaces of the two modules 301 when making arc-shaped bends.

[0044] Working principle:

[0045] Step 1: When it is necessary to bend the aluminum alloy into a right angle, rotate the adjusting plate 203. The adjusting plate 203 drives the screw ring 202 to move closer together through the lead screw 201, so that the two modules 301 are in contact with each other. After the right angle pressure block 507 is released from the punch 501, it is fixed by inserting the pin 506 into the through hole 505 and the fixing hole 504 below. The aluminum alloy plate placed on the surface of the two modules 301 can be bent into a right angle by the 90-degree angle between the two modules 301 and the right angle pressure block 507.

[0046] Step 2: When it is necessary to bend into an arc shape, rotate the adjustment plate 203. The adjustment plate 203 drives the screw ring 202 to move closer together through the lead screw 201, separating the two modules 301 from each other, exposing the arc groove 4 on the surface of the base 1. After the right angle pressure block 507 is put into the punch 501, it is fixed inside the punch 501 by inserting the pin 506 into the through hole 505 and the upper fixing hole 504. The right angle pressure block 507 is then fixed inside the punch 501 by pressing down the aluminum alloy plate placed on the surface of the two modules 301 through the inclined surface of the opposite side of the two modules 301 and the arc surface of the arc groove 4.

[0047] Step 3: When bending the irregular surface, rotate the adjusting plate 203. The adjusting plate 203 drives the screw ring 202 to move closer together through the lead screw 201, separating or bringing the two modules 301 closer together. Adjust the distance between the connecting holes 9 of the molds on both sides to fit the connecting pin of the existing irregular mold. Then insert the irregular mold into the surface of the two modules 301 to complete the assembly. Then use the hydraulic equipment 502 to squeeze and bend.
