[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0020] Please refer to Figure 1-3 ;

[0021] The rework jig of the present invention is intended to rework defective products 31, realize resource reuse and improve utilization rate. Under normal circumstances, the card point 32 needs to be bent inward at a certain angle, and the defect in the product 31 is that the bending angle of the card point 32 is not enough or it is not bent during stamping, which is called a bad point. Therefore, the jig is intended to bend the card point 32 to meet the requirements; specifically, it includes a base plate 1, a fixing seat 21 is provided on the base plate 1, and a placement position 22 for the product 31 to enter is provided on the fixing seat 21, which is located on at least one side of the fixing seat 21. A manual slide 41 is movably connected, and the manual slide 41 can move relative to the fixed seat 21. The specific method can be that the manual slide 41 is slidably connected to the bottom plate 1, or a fixed slide rod 53 is further provided on the side of the fixed seat 21, and the fixed slide rod 53 is inserted into the manual slide 41 and slidably connected thereto, which can play the role of position limitation and sliding, or the slide can be provided with the above two sliding methods, which are not limited here; a plurality of ejector knives 42 are provided in the manual slide 41, and the ejector knives 42 penetrate the fixed seat 21 and can extend to the placement position 22;

[0022] The card point 32 in the product 31 is set on its side. When in use, the product 31 is placed in the placement position 22, and the side of the product 31 is tightly attached to the side wall of the placement position 22, and the card point 32 is aligned with the outlet of the ejector 42. The middle of the product 31 is hollow. Specifically, you can use your hand to reach into the product 31 and apply pressure to the side from the inside to the outside to keep the side of the product 31 in close contact with the side wall of the placement position 22. Initially, the manual slide 41 is in a state away from the fixed seat 21, and the ejector 42 is retracted into the fixed seat 21. Push the manual slide 41 toward the fixed seat 21 by hand so that the ejector knife 42 extends from the fixed seat 21 and is inserted into the product 31 to contact the card point 32, thereby pushing the card point 32 to bend inward and straighten it. The bending angle requirement of the card point 32 can be specifically based on the extended length of the ejector knife 42. Of course, it is generally fixed. The corresponding ejector knife 42 is used according to the requirements of different products 31, and during the operation, the manual slide is in contact with the side of the fixed seat 21, so the extension amount of the ejector knife 42 is fixed.

[0023] In one embodiment, the bending angle of the clamping point 32 is not too large, so the ejector blade 42 only extends a little from the placement position 22. Preferably, the end of the ejector blade 42 is provided with a convex surface 45 for contacting the clamping point 32.

[0024] After the operation is completed, the manual slide 41 moves away from the fixing seat 21 , and the ejector knife 42 is also drawn out from the product 31 and retracted into the fixing seat 21 .

[0025] Typically, a product 31 has more than one card point 32 on the same side. Therefore, the jig of the present invention can be used to rework multiple card points 32 at one time, and the process can be completed in a few seconds at the fastest. The operation is simple and fast, which reduces waste and improves the utilization rate of defective products.

[0026] In an embodiment of the present utility model, the manual slide 41 is connected to the fixed seat 21 by a screw 51, and a spring 52 is provided on the screw 51. The spring 52 contacts the manual slide 41. A longer screw 51 is used for connection so that there is a movable margin between the manual slide 41 and the fixed seat 21. The manual slide 41 is pressed toward the fixed seat 21 and then released. It can be reset by the spring 52, and the release is convenient.

[0027] In the embodiment of the utility model, a vertically extending flange 23 is provided in the placement position 22, and a special-shaped slot 24 is formed between the flange 23 and the side wall. The special-shaped slot 24 is adapted to the end of the product 31, and an entrance is formed on the upper end face of the fixing seat 21. When in use, the product 31 is inserted into the special-shaped slot 24 from top to bottom, which has the effect of fixing the product 31, so that the side of the product 31 is tightly attached to the side wall of the placement position 22, and there is no need to manually apply external force.

[0028] The clamping point 32 is located close to the flange 23 , and a 90° bend may be required at the clamping point 32 , so there is a space between the flange 23 and the clamping point 32 .

[0029] In the embodiment of the present invention, the manual slide 41 is provided with several channels for the ejector knife 42 to pass through, and the end of the ejector knife 42 is provided with a boss 43, which can interfere with the outer wall of the manual slide 41. Such a design can realize the replacement of the ejector knife 42 to adapt to the requirements of different products 31. In addition, the design of the boss 43 can prevent the ejector knife 42 from excessively extending into the product 31 and affecting the bending angle of the card point 32. Of course, using this method, it is necessary to press the ejector knife 42 to avoid it popping out when it interferes with the card point 32. Of course, several ejector knives 42 can also be fixed by screws. There are many ways of fixing in the existing technology, which are not limited here.

[0030] Furthermore, a groove 44 is provided on the outer side of the manual slide 41 corresponding to the channel entrance position, and the boss 43 is located in the groove 44 so that the end face of the ejector knife 42 is flush with the side face of the manual slide 41, and the groove 44 can be used to install a locking piece (not shown) to fix the ejector knife 42.

[0031] In the present invention, the manual slide 41 has two respectively arranged on both sides of the fixed seat 21, and there are two corresponding placement positions 22 and special-shaped card slots 24. In this embodiment, the placement position 22 is relatively large, so it can be suitable for rework processing of products 31 of two sizes, and there are card points 32 on both sides of the product 31. For the larger product 31, its two ends can be simultaneously inserted into the two special-shaped card slots 24. For the smaller product 31, one end can be inserted into the corresponding special-shaped card slot 24 as needed.

[0032] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0033] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementations that can be understood by those skilled in the art.
