Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1-7A high-quality aluminum alloy bright strip single-station quick-change stamping mechanism, comprising: The lower die 100 is fixed at the die placement location of the stamping device; The upper die 200 is fixed at the output end of the hydraulic cylinder of the stamping device and located directly above the lower die 100; The guide pillars 300 are vertically fixed at the four corners of the lower mold 100 and the upper mold 200 to guide the upper mold 200 in the up and down direction. The lower mold 100, the upper mold 200 and the guide pillars 300 form a mold frame. This application can be used as a general structure. Station 400 is evenly distributed on the lower mold 100; Mounting slot 500 is correspondingly opened on workstation 400; The workstation plate 600 is placed in the mounting slot 500 to hold the mold core; The locking block 700 is fixed at the end of the mounting groove 500 and is used to fix the workstation plate 600. The locking block 700 is fixed at the end of the mounting groove 500 by screws.

[0019] In use, each workstation plate 600 holds a corresponding aluminum alloy precision forging die core. Each time the upper die 200 presses down the lower die 100, the die core on each workstation plate 600 completes the corresponding stamping work. When it is necessary to change workstations 400, simply remove the workstation plate 600 on the corresponding workstation 400 and replace it with a new workstation plate 600. The process is as follows: first, remove the locking block 700, then pull out the workstation plate 600, then insert the new workstation plate 600 into the mounting slot 500, and finally tighten the locking block 700. Alternatively, it can be removed without replacing the workstation plate 600. Each workstation 400 is independent of each other. During maintenance, the corresponding workstation plate 600 is removed and then maintenance is performed, which is quick and efficient.

[0020] Please see Figure 5 , Figure 6 and Figure 7 The mounting groove 500 has a slot 501 at the end, and the work station plate 600 has a plug plate 601 fixed at both ends. The plug plate 601 is adapted to the contact point of the slot 501 and the locking block 700.

[0021] In use, the engagement of slot 501 with insert plate 601 and the engagement of insert plate 601 with locking block 700 can increase the limit of the station plate 600 after it is fixed.

[0022] Please see Figure 1 , Figure 6 , Figure 8 and Figure 9 The locking block 700 includes a block 701 fixed to the end of the mounting groove 500, and: A through screw hole 703 is provided on one side of the block 701 for easy screw use; An inclined abutment surface 702 is provided in the middle of the other side of the block 701, and the inclined abutment surface 702 is adapted to the surface of the insert plate 601; A movable groove 704 is provided at the inclined abutment surface 702 for the use of the abutment plate 705; Abutment 705 is connected inside the movable slot 704; A sliding groove 706 is formed inside the block 701. The extension line of the sliding groove 706 is perpendicular to the surface of the abutment plate 705, which facilitates processing. The end of the sliding groove 706 passes through one side of the screw hole 703 and communicates with the inside of the screw hole 703. A sliding rod 707 is slidably connected inside the sliding groove 706. One end of the sliding rod 707 is vertically fixed to the middle of the abutment plate 705, and the other end of the sliding rod 707 passes through one side of the screw hole 703. A reset member 708 is connected between the outer side of the middle part of the sliding rod 707 and the middle part of the sliding groove 706. The reset member 708 is a spring.

[0023] In use, when tightening the locking block 700, first bring the inclined abutment surface 702 into contact with the surface of the insert plate 601, then insert the screw into the screw hole 703, and tighten it. The screw contacts the sliding rod 707, causing the sliding rod 707 to slide into the sliding groove 706, pressing the reset piece 708. The sliding rod 707 sliding into the sliding groove 706 drives the abutment plate 705 to move outward, thereby causing the abutment plate 705 to abut against the surface of the insert plate 601, thus increasing the fixing effect. When the insert plate 601 is subjected to impact and shaking, the abutment plate 705 will move back, thereby driving the sliding rod 707 to slide towards the screw surface, so that the sliding rod 707 is inserted into the screw surface, fixing the screw to a certain extent and making the fixing effect more obvious.

[0024] Among them, the reset component 708 is a spring, and the block 701 has a receiving groove at the position of the reset component 708 to facilitate the placement of the reset component 708. The inner diameter of the receiving groove is larger than the inner diameter of the sliding groove 706. If the inner diameters are the same, the spring can move easily; if the inner diameters are smaller, it cannot be used.

[0025] Please see Figure 9 and Figure 10 The abutment 705 includes a base plate 705a vertically fixed to one end of the sliding rod 707. The base plate 705a is a metal plate, and this application uses steel plate for manufacturing. A rubber sheet 705b is laid on the surface of the substrate 705a, and the rubber sheet 705b is glued to the surface of the substrate 705a. An arc-shaped pad 705c is provided between the rubber plate 705b and the substrate 705a. The arc shape of the arc-shaped pad 705c can play an elastic role, which can help increase the overall elasticity. The protrusions 705d are evenly fixed on the surface of the rubber sheet 705b, and the protrusions 705d serve to increase friction.

[0026] In use, the protrusion 705d increases the friction with the surface of the insert plate 601, and the rubber plate 705b increases the elasticity, which can further increase the friction effect of the protrusion 705d, so as to restrict the position of the insert plate 601.

[0027] Among them, the arc-shaped pad 705c has an embedded elastic arc plate to increase the support strength and prevent excessive elasticity from affecting the normal fixing effect. In addition, there are gaps between the arc-shaped pads 705c to allow space when the arc-shaped pads 705c are deformed under pressure.

[0028] Please see Figure 1 , Figure 3 and Figure 4 Elastic support columns 800 are provided between the guide columns 300. The elastic support column 800 is a type of elastic telescopic rod. Its structure is a telescopic rod plus a spring, which is a conventional structure.

[0029] The lower die 100 is fixed with an installation strip, which is fixed to the die placement location of the stamping device by bolts.

[0030] When in use, the installation strip facilitates the installation of the lower mold 100.

[0031] Please see Figure 3 and Figure 5 The mounting groove 500 has a limit groove at the position of the locking block 700, and the bottom of the locking block 700 is fixed with a limit block.

[0032] When in use, the combination of the limiting groove and the limiting block can increase the fixing effect when the locking block 700 is fixed.

[0033] Among them, anti-interference partitions are installed between workstations 400. The anti-interference partitions are a type of partition to prevent interference between each workstation 400.

[0034] Working principle: First, the corresponding aluminum alloy precision forging is placed on each stamping die core. The upper die 200 presses down on the lower die 100, so that the die core on each station plate 600 can complete the corresponding stamping work. When it is necessary to change the station 400, simply remove the station plate 600 on the corresponding station 400 and replace it with a new station plate 600. The process is as follows: first, loosen the screws and remove the plate, then disassemble the block 701, then pull out the station plate 600, and then insert the new station plate 600 into the mounting slot 500. The insert plate 601 is inserted into the slot 501, and the inclined abutment surface 702 is aligned with the other end of the insert plate 600. 01. After surface contact, the screw is finally inserted into the screw hole 703 and tightened. The screw contacts the sliding rod 707, causing the sliding rod 707 to slide into the sliding groove 706, pressing the reset piece 708. The sliding rod 707 slides into the sliding groove 706, causing the abutment plate 705 to move outward, so that the abutment plate 705 abuts against the surface of the insert plate 601, thereby increasing the fixing effect. When the insert plate 601 is subjected to impact and shaking, the abutment plate 705 will move back, thereby causing the sliding rod 707 to slide towards the screw surface, so that the sliding rod 707 is inserted into the screw surface, fixing the screw to a certain extent.

[0035] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
