Description

Technical Field

[0001] This utility model relates to the field of fixture technology, and in particular to a fixing fixture for a metal processing punch press. Background Technology

[0002] Metal processing typically involves using a punch press, which is a stamping press. Compared to traditional machining, stamping offers advantages such as material and energy savings, high efficiency, lower operator skill requirements, and the ability to produce products unattainable through machining using various molds. Therefore, its applications are becoming increasingly widespread. Stamping production is primarily for sheet metal. When processing metal with a punch press, a fixture is usually used to fix the metal in place and prevent it from shifting during processing. Currently, the fixtures on existing metal processing punch presses are typically directly mounted on the press.

[0003] Existing fixtures are generally set on the worktable of a punch press, which has a stamping cavity. For clamping and positioning of sheet-shaped workpieces, two limiting plates are generally used for positioning, which has poor clamping flexibility and needs to be improved and optimized.

[0004] Therefore, this utility model proposes a metal processing punch press fixing fixture to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a metal processing punch press fixing fixture to solve the problems mentioned in the background art.

[0016] The technical solutions in the embodiments of this utility model will be clearly and completely described below. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] Please see Figures 1 to 4 The present invention provides a technical solution: a metal processing punch press fixing fixture, including a worktable 1 and a punching cavity 2 disposed at the center of the top of the worktable 1; A limit slide 3 and an adjustment groove 4 are provided in the workbench 1, and the limit slide 3 is located at the bottom of the adjustment groove 4. A limiting component is provided in the limiting slide 3. The limiting component includes a support shaft 501 and an auxiliary component provided on the top of the support shaft 501. The auxiliary component limits the plate shape, and the support shaft 501 is positioned by the provided positioning structure.

[0018] In this scheme, when positioning a plate-shaped workpiece during stamping, the plate is first placed on the worktable 1. Then, the positions of each support shaft 501 are adjusted so that the limiting threaded pin 703 contacts the side wall of the plate-shaped workpiece. The position of the support shaft 501 is then positioned using the positioning structure, and the limiting threaded pin 703 is tightened. This process is convenient for both installation and disassembly of the limiting components. The multiple sets of support shafts 501 and auxiliary components provide a good positioning effect not only for square and rectangular plates but also for round plates, offering good operational flexibility. The support shaft 501 is placed in the regulating groove 4, with a base plate 502 fixedly installed at the bottom end and a connecting threaded part 503 at the top. This connecting threaded part 503 is threadedly connected to a connecting nut 504, which in turn connects to the auxiliary components. The base plate 502 is located in the limiting slide groove 3.

[0019] When it is necessary to position the support shaft 501, according to the attached... Figure 1-2As shown, the positioning structure includes a fixed plate 601 mounted on the support shaft 501, with threaded holes 602 in the fixed plate 601. These threaded holes 602 are evenly spaced in a ring within the fixed plate 601 and are threadedly connected to positioning screws 603. A knob cap 604 is fixedly mounted on the top of the positioning screw 603. Positioning the support shaft 501 involves rotating the knob cap 604 to tighten the positioning screw 603. To further improve positioning stability, the positioning structure also includes anti-slip texture 605, which is located on the worktable 1 and on one side of the slot at the top of the control groove 4. This means that rotating the positioning screw 603 using the knob cap 604 causes the bottom of the positioning screw 603 to contact the anti-slip texture 605, after which the positioning screw 603 is tightened further.

[0020] Combined with the appendix Figure 3-4 As shown, when positioning rectangular or square plate-shaped workpieces, the sides of the workpiece are straight. That is, after placing the workpiece on the worktable 1, when moving the support shaft 501, the bottom end of the limiting threaded pin 703 used to limit the workpiece needs to contact the surface of the worktable 1. At this time, it is only contact and does not need to be tightened. Then, move the position of the support shaft 501 until the limiting threaded pin 703 contacts and limits the side wall of the plate. Then, the positioning structure is used to position the support shaft 501. Finally, the limiting threaded pin 703 is tightened by the auxiliary handle 705. The auxiliary component includes a support plate 701 set on the side wall of the connecting nut 504. A bearing head 702 is fixedly set at the other end of the support plate 701. The limiting threaded pin 703 is threaded through the bearing head 702. The top end of the limiting threaded pin 703 is fixedly set with the auxiliary handle 705.

[0021] To further improve the stability of the limiting threaded pin 703 after it is tightened, that is, to enhance its limiting effect on the workpiece, this solution also provides an anti-slip pad 704 at the bottom end of the limiting threaded pin 703.

[0022] If it is necessary to position a circular plate, in order to better ensure that the limiting threaded pin 703 contacts and fits against the side wall of the circular plate, this solution provides a connecting threaded part 503 on the top of the support shaft 501, and the connecting threaded part 503 is threadedly connected to the connecting nut 504. The two work together to provide a rotational adjustment effect, that is, the limiting threaded pin 703 can be made to contact the side wall of the plate by rotating the connecting nut 504. Then, the support shaft 501 is positioned, and the limiting threaded pin 703 is tightened by the auxiliary handle 705. The positioning of the circular plate is then completed.

[0023] The multiple sets of limiting components set on the workbench 1 can not only provide a suitable positioning effect for plates of different shapes, but also position plates of the same shape but different sizes, which is flexible and adaptable to work.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
