Description

Technical Field

[0001] The present application relates to the technical field of asynchronous jigs, and in particular to a half-cutting asynchronous jig. Background Art

[0002] The asynchronous fixture for half-cut blanking is a device used in the half-cut blanking process. Its main function is to ensure the stability and accuracy of the workpiece during the half-cut blanking process. The design of the asynchronous fixture can be adjusted according to the shape and size of different workpieces to ensure that the workpiece will not move or deform during the processing.

[0003] When the die-cutting and half-cutting are asynchronous, the knife marks are cut on the main material strip, which causes knife marks on the main material strip and affects the process production. In view of the technical problem mentioned above, a new bottom plate jig is developed. Through the double-layer structure design, the main material strip is free of knife marks after being asynchronous, thus solving the above-mentioned problem. Utility Model Content

[0004] In view of the shortcomings of the prior art, the present application provides a half-cut blanking asynchronous jig, which has the advantages of a double-layer adjustable jig and no knife marks left after asynchronous die-cutting.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a half-cutting and blanking asynchronous jig, comprising an upper jig and a lower jig mounted on a workbench, the upper jig being provided with a knife row and foam for completing the cutting, the workbench being provided with a connecting structure, and a bottom platform for the main material belt to pass through being fixedly mounted on the inner bottom wall of the workbench;

[0006] The connection structure comprises a fixed block fixed on the top of the base, a bracket slidably connected to the fixed block and a support plate fixedly connected to the bracket, and the lower jig is fixed on the support plate.

[0007] Furthermore, the foam is located on one side of the knife row and the lower end exceeds the end of the knife row by 2 mm.

[0008] Furthermore, a cylinder for pushing the upper jig to move is fixedly mounted on the inner top wall of the workbench, a power end of the cylinder is directly connected to the upper jig, and a bottom platform for the main material belt to pass through is fixedly mounted on the inner bottom wall of the workbench.

[0009] Furthermore, the upper tooling comprises a bottom plate and a knife row plate which are detachably mounted on the cylinder, and the knife row is fixedly mounted on the knife row plate.

[0010] Furthermore, a groove for positioning the knife row plate is formed through the side of the bottom plate, and a positioning pin is protruded from one side surface of the knife row plate attached to the bottom plate, and the positioning pin is plugged into the end of the groove correspondingly.

[0011] Furthermore, a first pad and a second pad for fixing the knife row plate are fixedly mounted on the bottom plate by bolts.

[0012] Furthermore, the second pad includes two pieces, the two second pads are distributed at the position where the groove is provided on the bottom plate, and the second pad is provided with a material running groove corresponding to the positioning pin.

[0013] Furthermore, the fixing block and the bracket are divided into two groups and are symmetrically installed on the base platform front and back.

[0014] Furthermore, a slide groove is provided inside the fixed block, and a slide plate is fixedly connected to one end of the bracket extending into the slide groove. An adjustment rod is rotatably installed in the fixed block, and the slide plate is threadedly connected to the adjustment rod.

[0015] Furthermore, one end of the adjusting rod extends to the outside of the fixing block, and a bolt is fixedly mounted on the end of the adjusting rod extending to the outside of the fixing block.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0026] See also Figure 1-6 In this embodiment, a half-cutting asynchronous jig includes an upper jig and a lower jig 6 installed on a workbench 1. The upper jig is provided with a knife row 8 and a foam 13 for completing the cutting. The foam 13 is located on one side of the knife row 8 and the lower end exceeds the end of the knife row 8 by 2 mm. It is used to squeeze the main material after cutting, so that the main material is pressed down to the main material belt for transmission.

[0027] It should be noted that a cylinder 3 for pushing the upper jig to move is fixedly installed on the inner top wall of the workbench 1, a base 2 for the main material belt to pass through is fixedly installed on the inner bottom wall of the workbench 1, and a connecting structure is provided on the base 2 for installing the lower jig 6. The power end of the cylinder 3 is directly connected to the upper jig, and the upper jig movement can be loaded through the cylinder 3.

[0028] Specifically, the upper tooling includes a base plate 4 and a knife row plate 7 detachably mounted on the cylinder 3. The knife row 8 is fixedly mounted on the knife row plate 7. A groove 12 for positioning the knife row plate 7 is also penetrated through the side of the base plate 4. A positioning pin 11 is protruded from one side surface of the knife row plate 7 that is attached to the base plate 4. The ends of the positioning pin 11 and the groove 12 are correspondingly plugged in to achieve the snap-fit ​​positioning of the knife row plate 7 relative to the base plate 4.

[0029] It should be noted that the base plate 4 is also fixed with a first pad 9 and a second pad 10 for fixing the knife row plate 7 by bolts, wherein the second pad 10 includes two pieces, and the two second pads 10 are distributed at the position where the groove 12 is opened in the base plate 4, and the second pad 10 is provided with a material feeding groove 14 corresponding to the positioning pin 11.

[0030] Specifically, the back side of the second pad 10 needs to be milled to a depth of 0.6 mm, and one end of the bottom plate 4 needs to be milled with a rounded corner.

[0031] In this embodiment, the connection structure includes a fixed block 16 fixed to the top of the base 2 , a bracket 15 slidably connected to the fixed block 16 , and a support plate 5 fixedly connected to the bracket 15 , and the lower jig 6 is fixed on the support plate 5 .

[0032] Preferably, the fixing block 16 and the bracket 15 are divided into two groups and are symmetrically installed on the base 2 front and back, so that the space between the lower jig 6 and the base 2 is hollow to facilitate the passage of the main material belt.

[0033] In the present application, the main material is cut by cooperating with the upper jig through the overhead mounted lower jig 6. Since the knife row 8 falls directly on the lower jig 6, the main material belt does not flow back under the knife mark. At the same time, the main material can be cut and pressed down to the main material belt for transmission after the foam 13 is asynchronous.

[0034] It should be noted that a slide groove 17 is further provided inside the fixed block 16 , a slide plate 18 is fixedly connected to one end of the bracket 15 extending into the slide groove 17 , an adjustment rod 19 is rotatably installed in the fixed block 16 , and the slide plate 18 is threadedly connected to the adjustment rod 19 .

[0035] One end of the adjusting rod 19 extends to the outside of the fixing block 16 , and a bolt is fixedly installed on the end of the adjusting rod 19 extending to the outside of the fixing block 16 , so that the adjusting rod 19 can be conveniently pulled to rotate by using a tool.

[0036] In a specific implementation, by rotating the adjustment rod 19, the position of the slide plate 18 can be adjusted under the threaded fit, and the positions of the bracket 15 and the support plate 5 can be further adjusted to adapt to the main material belt.

[0037] The working principle of the above embodiment is:

[0038] The lower jig 6 is installed and set through the support plate 5 suspended on the base 2, and then the main material belt is passed through the gap between the support plate 5 and the base 2 for feeding, and the main material is conveyed and cut by the pressure roller. Under the reciprocating traction of the cylinder 3, the knife row 8 on the upper jig falls and fits the lower jig 6 to complete the cutting of the main material conveyed by the pressure roller. At the same time, the cut main material is pressed down to the main material belt extending from the bottom of the support plate 5 by the foam 13 located on one side of the knife row 8, so that no cutting marks are left on the surface of the main material belt. At the same time, the adjusting rod 19 can be rotated to make the adjusting rod 19 drive the sliding plate 18 connected with the external thread to slide in the slide groove 17, so that the bracket 15 connected to the outside of the support plate 5 extends to adjust the height position of the lower jig 6, which is convenient for adapting to the main material belt.
