Abstract
Description
Technical Field
[0001] This utility model relates to the field of sheet metal processing technology, and in particular to a positioning auxiliary device for sheet metal processing. Background Technology
[0002] Currently, sheet metal part positioning auxiliary devices are tools used to accurately determine the position of sheet metal parts during sheet metal processing. They help ensure the positional accuracy of sheet metal parts during cutting, bending, drilling, and other processing.
[0003] A bending machine is disclosed in Chinese utility model patent with publication number CN220612046U. Although the above-mentioned prior art uses clamping plates to hold and fix the workpiece, thereby avoiding the deviation and tilting caused by manual hand transport, the sheet metal needs a certain range of motion during the bending process after the clamping plates hold the sheet metal and the bending machine presses down to bend the sheet metal. Otherwise, the sheet metal will be subjected to both bending by the bending machine and clamping by the clamping plates. Under the action of these two forces, the sheet metal will deform. Not only will the bending position be bent, but even the clamped position will be deformed, which will cause damage to the sheet metal. Therefore, it is necessary to design a sheet metal processing positioning auxiliary device that can automatically release the clamping of the sheet metal during bending. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a sheet metal part processing positioning auxiliary device.
[0005] This utility model is achieved by the following technical solution: a sheet metal part processing positioning auxiliary device, including a bending machine, wherein the bending platform of the bending machine is provided with a clamping component capable of positioning and clamping the sheet metal part, and one side of the clamping component is provided with an unlocking component that automatically unlocks the clamping component when the bending machine bends the sheet metal part, the clamping component includes a replacement base provided on one side of the bending machine, a support plate fixedly installed on the top of the replacement base, and a clamping plate rotatably installed on the support plate.
[0006] With the above technical solution, when bending sheet metal parts, it is only necessary to place the sheet metal parts on the clamping assembly, and then close the clamping assembly to clamp the sheet metal parts. When the bending machine presses down to bend, the unlocking assembly will be triggered, and the unlocking assembly will open the clamping assembly. At this time, the bending machine has already pressed the sheet metal parts tightly, thus avoiding the sheet metal parts from conflicting with the clamping assembly and deforming when being bent.
[0007] As a further improvement to the above solution, a clamping groove is provided on one side of the clamping plate that is in contact with the support plate, and a rubber plate is fixedly installed inside the clamping groove.
[0008] With the above technical solution, the rubber sheet will fit snugly against the sheet metal part, thus preventing the sheet metal part from moving.
[0009] As a further improvement to the above solution, a sliding groove is provided on the bending platform of the bending machine, and a sliding block is slidably fitted inside the sliding groove. The sliding block is fixedly connected to the replacement base.
[0010] With the above technical solution, the position of the replacement base can be adjusted by sliding the sliding block inside the sliding groove, and the sliding block can be removed from the sliding groove so that the replacement base can be replaced.
[0011] As a further improvement to the above solution, the unlocking component includes a push plate fixedly installed on one side of the clamping plate, a sealing sleeve disposed on the top of the push plate and having a sliding hole, and a push column slidably sealed inside the sliding hole. The top of the sealing sleeve is fixedly connected to an oil pipe, and one end of the oil pipe is fixedly connected to an elastic oil bag.
[0012] Through the above technical solution, when the elastic oil bag is pressed down by the bending machine, the oil inside will be squeezed into the oil pipe, and then input into the sealing sleeve through the oil pipe. This will squeeze the push column inside the sealing sleeve, thereby causing the push column to squeeze the push plate.
[0013] As a further improvement to the above solution, the upper part of the oil pipe is fitted with a connecting plate that is fixedly installed with the replacement base, the cylindrical surface of the sealing sleeve is fixedly fitted with a fixing plate that is fixedly installed with the connecting plate, and the inside of the sealing sleeve is provided with a retraction spring, the two ends of which are fixedly connected to the top of the inner cavity of the sealing sleeve and the top of the push column, respectively.
[0014] With the above technical solution, after the push column is pushed out of the sealing sleeve, the return spring will be pulled open. When the elastic oil bag stops outputting oil, the return spring will pull the push column back into the sealing sleeve, thereby allowing the push plate to return to its original position.
[0015] As a further improvement to the above solution, the elastic oil bag is located at the position where the bending machine bends the sheet metal part.
[0016] With the above technical solution, when the bending machine bends sheet metal parts, it will press down on the sheet metal parts and the elastic oil bag.
[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0018] This invention, by setting up a clamping component and an unlocking component, allows for bending of sheet metal parts. Simply place the sheet metal part on the clamping component, then close the clamping component to hold the sheet metal part. When the bending machine presses down to bend, the unlocking component is triggered, which opens the clamping component. At this point, the bending machine has already pressed the sheet metal part firmly, thus avoiding any conflict between the sheet metal part and the clamping component that could cause deformation during bending.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0026] Please combine Figures 1-4 This embodiment of a sheet metal part processing positioning auxiliary device includes a bending machine 1. The bending platform of the bending machine 1 is provided with a clamping component capable of positioning and clamping the sheet metal part. One side of the clamping component is provided with an unlocking component that automatically unlocks the clamping component when the bending machine 1 bends the sheet metal part.
[0027] When bending sheet metal parts, simply place the sheet metal parts on the clamping assembly, then close the clamping assembly to hold the sheet metal parts. When the bending machine 1 presses down to bend, it will trigger the unlocking assembly, which will open the clamping assembly. At this time, the bending machine 1 has already pressed the sheet metal parts tightly, thus avoiding the sheet metal parts from conflicting with the clamping assembly and deforming when being bent.
[0028] The clamping assembly includes a replacement base 201 disposed on one side of the bending machine 1, a support plate 202 fixedly installed on the top of the replacement base 201, and a clamping plate 203 rotatably installed on the support plate 202. The clamping plate 203 has a clamping groove on one side that is in contact with the support plate 202, and a rubber plate 4 is fixedly installed inside the clamping groove.
[0029] The clamping plate 203 will work with the rubber plate 4 to clamp the sheet metal parts, so that the sheet metal parts will not move.
[0030] The bending platform of the bending machine 1 is provided with a sliding groove 5, and a sliding block 6 is slidably fitted inside the sliding groove 5. The sliding block 6 is fixedly connected to the replacement base 201.
[0031] The sliding block 6 can be slid inside the sliding groove 5 to adjust the position of the replacement base 201, and the sliding block 6 can be removed from the sliding groove 5 to replace the replacement base 201.
[0032] The unlocking assembly includes a push plate 301 fixedly installed on one side of the clamping plate 203, a sealing sleeve 302 set on the top of the push plate 301 and having a sliding hole, and a push column 303 slidably sealed inside the sliding hole. The top of the sealing sleeve 302 is fixedly connected to an oil pipe 304, one end of the oil pipe 304 is fixedly connected to an elastic oil bag 305, a connecting plate 7 fixedly installed on the upper part of the oil pipe 304 and the replacement base 201, a fixing plate 8 fixedly installed on the cylindrical surface of the sealing sleeve 302 and the connecting plate 7, and a retraction spring 9 is provided inside the sealing sleeve 302. The two ends of the retraction spring 9 are fixedly connected to the top of the inner cavity of the sealing sleeve 302 and the top of the push column 303, respectively.
[0033] When the elastic oil bag 305 is pressed down by the bending machine 1, the oil inside will be squeezed into the oil pipe 304, and then input into the sealing sleeve 302 through the oil pipe 304. This will squeeze the push column 303 inside the sealing sleeve 302, so that the push column 303 will squeeze the push plate 301.
[0034] After the push column 303 is pushed out of the sealing sleeve 302, the return spring 9 will be pulled open. After the bending machine 1 is separated from the elastic oil bag 305, the elastic oil bag 305 will no longer output oil. The return spring 9 will pull the push column 303 back into the sealing sleeve 302, thereby allowing the push plate 301 to return to its original position.
[0035] The elastic oil bag 305 is located at the position where the sheet metal parts are bent by the bending machine 1.
[0036] When bending machine 1 bends sheet metal parts, it will press on the sheet metal parts and the elastic oil bag 305.
[0037] The implementation principle of a sheet metal part processing positioning auxiliary device in this application embodiment is as follows: when bending the sheet metal part, select the clamping plate 203 that is suitable for the current sheet metal part, insert the sliding block 6 into the sliding groove 5, and adjust the position of the replacement base 201 so that the sheet metal part can be placed on the support plate 202. Then, pull the clamping plate 203 by hand so that the clamping plate 203 cooperates with the rubber plate 4 to press the sheet metal part.
[0038] After the sheet metal part is pressed down by the clamping plate 203, the bending part of the bending machine 1 will be pressed down. After contacting the sheet metal part, it will also contact the elastic oil bag 305. Thus, when the sheet metal part is pressed down and bent, the elastic oil bag 305 will also be continuously pressed down.
[0039] When the elastic oil bag 305 is pressed down by the bending machine 1, the oil inside is squeezed into the oil pipe 304, and then input into the sealing sleeve 302 through the oil pipe 304. This will squeeze the push column 303 inside the sealing sleeve 302, and the push column 303 will be pushed out of the sealing sleeve 302. At this time, the return spring 9 will be pulled open, and the pushed column 303 will squeeze the push plate 301. After the push plate 301 is pushed downward, it will lift the clamping plate 203 off the support plate 202. In this way, the rubber plate 4 will separate from the sheet metal part, thereby avoiding the sheet metal part from being deformed due to the force generated by the clamping plate 203 when it is bent.
[0040] After the bending machine 1 completes the bending, the lower pressing part retracts and separates from the elastic oil bag 305. When the elastic oil bag 305 stops outputting oil, the retraction spring 9 pulls the push column 303 back into the sealing sleeve 302, thereby allowing the push plate 301 to return to its original position, which is convenient for clamping subsequent sheet metal parts.
[0041] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
