Description

Technical Field

[0001] The utility model belongs to the technical field of bending machines, and in particular relates to a front material supporting device with rolling wheels. Background Art

[0002] A bending machine is a mechanical device used to bend metal sheets. It is widely used in machinery manufacturing, shipbuilding, automobiles, electric power, steel structures and other industries. The main working parts of the bending machine are the upper and lower molds. The upper mold is pressed down by hydraulic or mechanical transmission to press the sheet into the V-shaped groove of the lower mold, so that the sheet is bent and deformed, thereby achieving the required bending angle and shape.

[0003] In order to facilitate the operator to place the plate on the mold, the bending machine is usually equipped with a front support device, that is, some components supporting the plate are set at the front end of the bending machine so that the plate can slide smoothly onto the mold. The design of the front support device has an important influence on improving the working efficiency and quality of the bending machine;

[0004] Most of the existing front support devices of bending machines do not have rolling wheels, that is, the components supporting the plate are fixed planes or grooves. The disadvantages of this front support device are that for light bending parts, the operator can directly place the steel plate on the mold for bending, but for heavier bending parts, direct operation is more laborious and inconvenient for the operator to operate for a long time, which ultimately affects production efficiency. In addition, due to the large friction resistance between the plate and the front support device, the plate is prone to scratches or deformation during movement, which reduces the quality of the product;

[0005] In order to solve the above problems, it is necessary to propose a front supporting device with rolling wheels. Utility Model Content

[0006] The purpose of the utility model is to provide a front support device with a rolling wheel, which can make the friction resistance between the steel plate and the rolling wheel very small, so that the steel plate can be pushed to the required position for bending more easily, reduce the friction between the steel plate and the surface of the support frame, reduce the labor intensity of workers, save the time of steel plate pushing, improve production efficiency, adopt the rolling wheel, reduce the scratches on the surface of the bent part, and improve the quality of the product.

[0007] The technical solution adopted by the utility model is as follows:

[0008] A front support device with a rolling wheel comprises a support frame, a mold is installed at one end of the top of the support frame, a plurality of fixed shafts are arranged at the top of the support frame and on one side of the mold, rolling wheels are sleeved on the outer sides of the fixed shafts, grooves are arranged at both ends of the rolling wheels, and rotating components are assembled on the inner sides of the grooves, and the rotating components are used to drive the rolling wheels to rotate on the fixed shafts.

[0009] Each of the rotating components includes a deep groove ball bearing arranged inside the groove, and the outer side of the deep groove ball bearing is clamped with the rolling wheel. Pressure covers are also installed at both ends of the rolling wheel, and the pressure cover is located inside the groove and extends a contact annular strip, which contacts the deep groove ball bearing.

[0010] The bottom and both sides of the fixed shaft and the inner side of the mounting groove are provided with fitting sheets, and the fitting sheets are fitted with the inner wall of the mounting groove.

[0011] The pressure cover and the rolling wheel are fixedly connected via a plurality of fixing screws.

[0012] The diameter of the rolling wheel is greater than the height of the gland.

[0013] The bonding sheet is made of flexible material.

[0014] The technical effects achieved by the utility model are:

[0015] In the utility model, when the steel plate is pushed onto the mold on the surface of the rolling wheel, the bearing drives the rolling wheel to rotate, so that the friction resistance between the steel plate and the rolling wheel is very small, the steel plate is easier to be pushed to the required position for bending, the friction between the steel plate and the surface of the support frame is reduced, the labor intensity of the workers is reduced, the time for pushing the steel plate is relatively saved, the production efficiency is improved, the rolling wheel is used to reduce the scratches on the surface of the bent part, and the quality of the product is improved.

[0022] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0023] like Figure 1-4 As shown, a front support device with rolling wheels comprises a support frame 1, on which a steel plate workpiece 8 is arranged, a mold 7 is installed at one end of the top of the support frame 1, and a groove body is arranged on the top of the mold 7, so that the bending mechanism can conveniently bend the steel plate workpiece 8, and a plurality of fixed shafts 3 are arranged on the top of the support frame 1 and on one side of the mold 7. The fixed shafts 3 are made of metal and can bear the weight of subsequent structures, and can be made of steel and other materials. A rolling wheel 4 is sleeved on the outer side of the fixed shaft 3, and the rolling wheel 4 is located on the outer side of the fixed shaft 3 and can rotate. The steel plate workpiece 8 is arranged on the rolling wheel 4, and the steel plate workpiece 8 is received by the rolling wheel 4;

[0024] When it is necessary to guide and push the steel plate workpiece 8 until it is close to the mold 7, the steel plate workpiece 8 can be placed on the rolling wheel 4, so that the rolling wheel 4 can rotate on the fixed shaft 3, thereby driving the steel plate workpiece 8 to move better, reducing the labor intensity of the workers, and relatively saving the pushing time of the steel plate workpiece 8, thereby improving production efficiency. By setting the rolling wheel 4, the scratches on the surface of the bent part can be reduced, and the quality of the product can be improved.

[0025] Grooves are provided at both ends of the rolling wheel 4 , and rotating components are installed inside the grooves. The rotating components are used to drive the rolling wheel 4 to rotate on the fixed shaft 3 .

[0026] See attached Figure 1-3 As shown, each rotating assembly includes a deep groove ball bearing 2 arranged inside the groove, and the outer side of the deep groove ball bearing 2 is clamped with the rolling wheel 4. The clamping can be carried out in any way, such as by the mutual clamping of the clamping strip and the clamping groove, etc. Of course, fixing by other means is also within the protection scope of the present application. Pressure caps 5 are also installed at both ends of the rolling wheel 4. The diameter of the rolling wheel 4 is greater than the height of the pressure cap 5. Through this arrangement, when the steel plate workpiece 8 is too wide and needs to be mounted on the upper part of the pressure cap 5, it can be carried by the rolling wheel 4 without contacting the pressure cap 5. The pressure cap 5 is located inside the groove and extends an abutting annular strip, which abuts against the deep groove ball bearing 2. The pressure cap 5 is used to fix the deep groove ball bearing 2 so that it will not slip when rolling.

[0027] When the rolling wheel 4 is guided by the deep groove ball bearing 2, the rolling wheel 4 can rotate more smoothly, thereby reducing the friction between the steel plate workpiece 8 and the rolling wheel 4, and further saving the advancement time of the steel plate workpiece 8. When installing the deep groove ball bearing 2, the deep groove ball bearing 2 on one side can be installed first, until the deep groove ball bearing 2 is installed in the groove, and the pressure cover 5 is installed. The deep groove ball bearing 2 is limited by the pressure cover 5. The pressure cover 5 and the rolling wheel 4 are fixedly connected by multiple fixing screws 6. At this time, the fixing screws 6 can be screwed in and the pressure cover 5 is restricted. When screwing the fixing screws 6, there is no need to tighten the fixing screws 6. According to the above method, after installing the deep groove ball bearing 2 and the pressure cover 5 on the other side, the fixing screws 6 on both sides are screwed and tightened to complete the installation of the deep groove ball bearing 2.

[0028] See attached Figure 4 As shown, the bottom and both sides of the fixed shaft 3 and the inner side of the mounting groove 9 are provided with a bonding sheet 10, and the bonding sheet 10 is in contact with the inner wall of the mounting groove 9. Through the setting of the bonding sheet 10, the fixed shaft 3 is installed on the inner side of the mounting groove 9 without rotation, thereby preventing the fixed shaft 3 from shaking and limiting the pushing effect of the steel plate workpiece 8 on the rolling wheel 4. The bonding sheet 10 is made of a flexible material. Through this setting, the bonding sheet 10 can fit tightly with the bracket 1 and prevent the fixed shaft 3 from directly contacting the bracket 1, thereby causing wear and damage to the fixed shaft 3 or the bracket 1, and the material of the bonding sheet 10 can be rubber or the like.

[0029] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
