Description

Technical Field

[0001] This invention relates to the field of cassette fixture technology, and particularly to a wire drawing fixture for titanium cassettes. Background Technology

[0002] A SIM card tray is an accessory used in mobile phones. Its structure consists of a card plate for holding the SIM card and a card cap located perpendicular to the card plate on one side. The width of the card cap is greater than the thickness of the card plate, meaning there is a gap between the card cap and both sides of the card plate along its thickness. The card plate is inserted into the phone, and the card cap fits snugly against the side wall of the phone. This type of SIM card tray is a metal part and requires a series of post-processing treatments such as sandblasting, oxidation, and wire drawing.

[0003] When performing wire drawing on card trays, the card trays to be processed are usually first placed into the corresponding card tray fixture, and then the surface of the card tray cap is wire drawn. The surface of the existing card tray fixture has several grooves for placing card trays. The width of the grooves is roughly the same as the width of the card tray plate. When performing wire drawing, the worker needs to place the card trays vertically into the grooves one by one. At this time, the card tray cap is slightly higher than the surface of the card tray fixture, and then the wire drawing is performed.

[0004] During the wire drawing process, because the card tray plate and the groove are not completely fitted, the card tray will inevitably wobble, resulting in uneven wire drawing effect on the surface of the card cap after wire drawing, and in severe cases, damage to the surface of the card cap.

[0005] Therefore, the inventor conducted in-depth research on the above-mentioned problems, which led to the creation of this case. Summary of the Invention

[0006] This invention provides a wire drawing fixture for titanium cassettes, aiming to solve the problems of incomplete fixation and easy shaking of existing cassettes in cassette fixtures.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] A drawing fixture for titanium card trays includes a base plate and a panel covering the base plate. The panel has a plurality of recesses for placing card trays. The recesses extend downward into the interior of the base plate, and there is a gap between the base plate and the panel. An elastic limiting component for engaging or disengaging from the recess is provided in the gap. One end of the base plate is also provided with a pusher component for entering the gap and pushing the elastic limiting component out of the recess.

[0009] Furthermore, taking the length direction of the base plate as the left and right direction, the top surface of the base plate is recessed with a placement groove for accommodating the elastic limiting component. The bottom of the placement groove is provided with a plurality of receiving blocks, which are arranged in a matrix. The top surface of each receiving block is recessed with a receiving hole for accommodating the card tray plate, and the side of the receiving block is also provided with a limiting groove for the elastic limiting component to be inserted.

[0010] Furthermore, the aforementioned panel is disposed above the placement groove, and the panel is provided with multiple raised strips arranged at intervals in the left-right direction. Each of the multiple raised strips is provided with several strip-shaped holes, which correspond to several receiving holes. The length of the strip-shaped holes is greater than the length of the receiving holes. A stepped groove for placing the card holder and the receiving block is formed between the strip-shaped holes of the panel and the receiving block. The strip-shaped holes and the receiving holes together form the aforementioned groove.

[0011] Furthermore, the aforementioned elastic limiting component is a movable plate, which has several rectangular holes. Several of the aforementioned receiving blocks pass through several of the aforementioned rectangular holes, and the width of the rectangular holes is greater than the width of the receiving blocks. The inner sidewall of each rectangular hole is provided with a special-shaped buckle for engaging with the aforementioned limiting groove. Several horizontally arranged springs are provided between the front side of the aforementioned movable plate and the adjacent sidewall of the placement groove. One end of the multiple springs abuts against the movable plate, and the other end abuts against the sidewall of the placement groove.

[0012] Furthermore, the side wall adjacent to the front side of the aforementioned placement groove and the movable plate is provided with a plurality of guide posts corresponding to the aforementioned spring, and one end of the spring is located inside the guide post.

[0013] Furthermore, the rear end of the aforementioned base plate is provided with a receiving groove for placing the aforementioned pushing component; the aforementioned pushing component is a movable block that is rotatably disposed in the receiving groove and can push the movable plate to move into the placement groove.

[0014] Furthermore, the aforementioned movable block is movably riveted into the receiving groove, and the end of the movable block facing the movable plate has an arc-shaped protrusion for pushing the movable plate.

[0015] Furthermore, the aforementioned panel is made of stainless steel.

[0016] The present invention also includes a wire drawing device, which is equipped with the above-mentioned wire drawing fixture.

[0017] As can be seen from the above description of the structure of the present invention, the present invention has the following advantages:

[0018] Firstly, the present invention provides a movable plate, a spring, and a pushing assembly between the base plate and the panel. The pushing assembly pushes the movable plate to move on the base plate, allowing the irregularly shaped buckles on the movable plate to engage or disengage from the grooves of the wire drawing fixture. This fixes the clips onto the wire drawing fixture, preventing them from shaking during the wire drawing process and ensuring the quality of the product after wire drawing.

[0019] Secondly, the method of fixing the card tray in the wire drawing fixture of the present invention is more convenient, which not only speeds up the feeding and fixing speed of the card tray, but also indirectly improves the production efficiency of the card tray wire drawing process.

[0020] Third, the wire drawing fixture of the present invention has a modular structure, which can be installed on any wire drawing equipment, making it more widely applicable. Attached Figure Description

Detailed Implementation

[0028] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] Fixtures are mainly used as tools to assist in controlling position or movement, and are widely used in various fields such as machinery, welding, and parts processing. Among them, chuck fixtures are mostly used to stabilize the chuck during processing, so that the chuck remains in a stable state during processing, which helps to ensure the processing accuracy of the workpiece and stabilize product quality.

[0030] Reference Figure 1 and Figure 2 A drawing fixture for titanium cassettes includes a base plate 10 and a panel 20 covering the base plate 10. The panel 20 is preferably made of stainless steel, which is highly corrosion-resistant and has a long service life. The panel 20 is recessed with a plurality of grooves for placing cassettes. The grooves extend downward into the interior of the base plate 10, and there is a gap between the base plate 10 and the panel 20. An elastic limiting component for engaging or disengaging from the groove is provided in the gap. One end of the base plate 10 is also provided with a pusher component for pushing the elastic limiting component out of the groove.

[0031] Reference Figures 1 to 4 With the length direction of the base plate 10 as the left-right direction, the top surface of the base plate 10 is recessed with a placement groove 11 for accommodating the elastic limiting component. The placement groove 11 is rectangular, and the bottom of the placement groove 11 is provided with a plurality of receiving blocks 12. The receiving blocks 12 are long strips and are arranged in a matrix. The top surface of each receiving block 12 is recessed with a receiving hole 121 for accommodating the card tray. The length of the receiving hole 121 is less than the length of the receiving block 12, and the side of the receiving block 12 is also provided with a limiting groove for the elastic limiting component to be inserted. 122; Panel 20 is placed on top of placement groove 11. Panel 20 has multiple raised strips 21 arranged at intervals in the left and right direction. Each of the raised strips 21 has a number of strip holes 211. The number of strip holes 211 correspond to a number of receiving holes 121, and the length of the strip holes 211 is greater than the length of the receiving holes 121. This makes it possible to form a stepped groove 22 for placing card holders and card caps between the strip holes 211 of panel 20 and the receiving block 12. The strip holes 211 and the receiving holes 121 together form the groove.

[0032] Reference Figures 1 to 6The elastic limiting component is a movable plate 30, which has several rectangular holes 31. Several receiving blocks 12 pass through several rectangular holes 31, and the width of the rectangular holes 31 is greater than the width of the receiving blocks 12, so that the movable plate 30 can move back and forth in the placement groove 11. The inner sidewall of each rectangular hole 31 is provided with a special-shaped buckle 311 for engaging with the limiting groove 122. The special-shaped buckle 311 can engage or disengage from the limiting groove 122 as the movable plate 30 moves back and forth, thereby fixing or unfixing the titanium card holder. Several horizontally arranged springs 4 are provided between the front side of the movable plate 30 and the adjacent sidewall of the placement groove 11. One end of each of the aforementioned springs 40 abuts against the movable plate 30, and the other end abuts against the side wall of the placement groove 11. To make the springs 40 more stable when compressed, multiple guide posts (not shown in the figure) can also be provided on the side wall of the placement groove 11. One end of the spring 40 passes through the guide post, and the other end abuts against the movable plate 30. Alternatively, both ends of the spring 40 can be fixed to the side wall of the placement groove 11 and the front side of the movable plate 30, respectively. It should be noted that the guide posts are provided on the side wall adjacent to the front side of the placement groove 11 and the movable plate 30 to further stabilize the springs 40. The guide posts will not interfere with the movement of the movable plate 30 in the placement groove 11.

[0033] The rear end of the base plate 10 is provided with a receiving groove 13 for placing the pusher assembly. The end of the receiving groove 13 that is close to the movable plate 30 has a flared opening. The pusher assembly is a movable block 50 that is riveted to the receiving groove 13. The movable block 50 can rotate left and right in the receiving groove 13. The end of the movable block 50 facing the movable plate 30 is provided with an arc-shaped protrusion 51 for pushing the movable plate 30. The arc-shaped protrusion 51 extends towards the movable plate 30 and gradually narrows. When the arc-shaped protrusion 51 of the movable plate 50 rotates to the middle of the receiving groove 13, the arc-shaped protrusion 51 abuts against the side wall of the movable plate 30 and pushes the movable plate 30 to move in the placement groove 11, thereby causing the irregular buckle 311 on the movable plate 30 to disengage from the limiting groove 122.

[0034] Reference Figures 1 to 6 During the wire drawing process, the movable block 50 is first rotated so that the arc-shaped protrusion 51 of the movable block 50 abuts against the movable plate 30, causing the irregular buckle 311 of the movable plate 30 to disengage from the limiting groove 122 of the receiving block 12. Then, the worker sequentially places the card into the groove formed by the strip hole 211 and the receiving hole 121. At this time, the card cap of the card is slightly higher than the protrusion 21 on the panel 20. Next, the movable block 50 is rotated to one side of the receiving groove 13 so that the arc-shaped protrusion 51 disengages from the movable plate 50. Under the action of the spring 40's rebound force, the irregular buckle 311 of the movable plate 50 abuts against the card plate of the card placed in the groove, thereby fixing the card onto the wire drawing fixture.

[0035] The wire drawing fixture of the present invention has a movable plate 30 between the base plate 10 and the panel 20. The movable plate 30 passes through the receiving block 12 of the base plate 10, and the movable plate 30 is also provided with a plurality of irregular buckles 311 for locking into the limiting groove 122 of the receiving block 12. By rotating the movable block 50, the arc-shaped protrusion 51 abuts against the movable plate 30, thereby causing the irregular buckles 311 of the movable plate 30 to disengage from the limiting groove 122 of the receiving block 12. Then the worker can load the card tray. After the loading is completed, the movable block 50 is rotated again to disengage the arc-shaped protrusion 51 from the movable plate 30. Under the action of the spring 40, the card tray can be quickly fixed on the wire drawing fixture. This is not only convenient and fast, but also improves the production yield.

[0036] The present invention also includes a wire drawing device, which is equipped with the above-mentioned wire drawing fixture, and the wire drawing device may be a metal wire drawing machine.

[0037] The above are merely specific embodiments of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial modifications made to the present invention using this concept shall be considered as infringing upon the protection scope of the present invention.
