Description

Technical Field

[0001] This utility model relates to the field of connector stamping die technology, specifically a stamping die for positioning connectors. Background Technology

[0002] Stamping dies are special process equipment used in cold stamping to process materials (metal or non-metal) into parts (or semi-finished products). They are also known as cold stamping dies. Stamping dies are installed on a press, and the pressure and power provided by the press cause the upper and lower dies of the die to move relative to each other, applying pressure to the sheet metal placed between them, causing it to undergo plastic deformation or separation, thereby obtaining parts of the required shape and size.

[0003] A search revealed that application number CN202020071331.5 discloses a communication connector stamping die for easy positioning. The die includes a lower base, an upper base fixedly mounted above the lower base, a left support rod fixedly connected to the left side of the lower and upper bases, and a right support rod fixedly connected to the right side of the lower and upper bases. Limit seats are fixedly mounted at the lower ends of the left and right support rods, which are then fixedly mounted to the lower base via the limit seats. A mounting base is fixedly mounted at the upper end of the upper base, and a hydraulic cylinder is fixedly mounted at the upper end of the mounting base. An upper template is movably mounted above the lower and upper bases, and a lower template is fixedly mounted below the upper template, located above the lower base. This communication connector stamping die for easy positioning can always run on a fixed trajectory, eliminating the need for positioning during each stamping operation, thus greatly facilitating the positioning and use of the stamping die.

[0004] However, when the above-mentioned device is used, it positions the upper and lower templates but lacks positioning for the connector. When the upper template is pressed down, the connector is prone to displacement and misalignment, resulting in insufficient dimensional accuracy and shape deviation of the connector after stamping, which seriously affects product quality.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example:

[0031] Please see Figures 1 to 7 This utility model provides a technical solution:

[0032] A stamping die for positioning a connector, comprising:

[0033] The base 1 has an installation part 105. Guide columns 6 are fixedly connected to both sides of the upper surface of the base 1. A fixing plate 2 is fixedly connected to the top of the guide column 6. A cylinder 5 is fixedly connected to the upper surface of the fixing plate 2. The output end of the cylinder 5 passes through the fixing plate 2 and reaches the other side to be fixedly connected to the upper surface of the protective shell 3.

[0034] A connecting ring 301 is fixedly connected inside the protective shell 3. The connecting ring 301 is slidably connected to the outside of the guide post 6. A mold punch 302 is fixedly connected inside the protective shell 3.

[0035] The mounting part 105 has sliding grooves 106 on both sides of its bottom, and positioning components are slidably connected to the sliding grooves 106.

[0036] Specifically, the connecting ring 301 is made of wear-resistant metal or engineering plastic, such as copper alloy or polytetrafluoroethylene, to ensure good sliding performance with the guide post 6.

[0037] Specifically, the positioning component includes a lower mold 4, with sliders 403 fixedly connected to both sides of the lower end face of the lower mold 4. The sliders 403 are slidably connected to the slide groove 106, and the lower end face of the lower mold 4 is in contact with the upper end face of the mounting part 105.

[0038] In this embodiment, the lower mold 4 is slidably connected to the sliding grooves 106 on both sides of the mounting part 105 of the base 1 via the slider 403, so that the lower end face of the lower mold 4 is in contact with the upper end face of the mounting part 105. The mounting part 105 is equipped with a limiting block 109 at the end of the sliding groove 106. After the lower mold 4 is slidably installed on the mounting part 105 along the sliding groove 106, the rear end of the lower mold 4 is in contact with the limiting block 109.

[0039] Specifically, a mounting block 102 is fixedly connected to the front end face of the base 1, and a limiting plate 103 is fixedly mounted on the mounting block 102 by a first mounting bolt 104. A rubber block 108 is fixedly connected to the inner side of the limiting plate 103, and the rubber block 108 is in contact with the front end face of the lower mold 4.

[0040] Specifically, the base 1 is made of high-strength metal materials, such as cast iron and steel, to ensure the stability and load-bearing capacity of the equipment.

[0041] In this embodiment, an "L"-shaped mounting block 102 is fixedly connected to the base 1. A limiting plate 103 is inserted from above the mounting block 102. A rubber block 108 is fixedly connected to the inner side of the limiting plate 103. The rubber block 108 is made of composite rubber material. After the limiting plate 103 is installed in place, the rubber block 108 abuts against the front end of the lower mold 4. The rubber block 108 has a certain elasticity and deforms under the cooperation of the limiting plate 103 and the lower mold 4. Since the limiting plate 103 is fixed by the mounting block 102, the rubber block 108 is pressed tightly against the lower mold 4, so that the lower mold 4 is fixed above the mounting part 105. In addition, the rubber block 108 has a certain coefficient of friction, which effectively prevents the lower mold 4 from shaking when the stamping mold is working.

[0042] Specifically, a positioning hole 401 is provided on the upper part of the lower mold 4, and a punch hole 402 is provided on the positioning hole 401 for stamping. The shape of the positioning hole 401 is consistent with the shape of the connector.

[0043] Specifically, the positioning component also includes a waste trough 107, which is disposed on the mounting part 105. The waste trough 107 passes through the mounting part 105 and is connected to the waste outlet 101 below the base 1. The punch 402 passes through the lower mold 4 and is connected to the waste trough 107.

[0044] In this embodiment, the lower mold 4 is provided with a positioning hole 401. The shape of the positioning hole 401 is the same as that of the connector, thereby positioning the connector. The shape of the positioning hole 401 is not fixed. The lower mold 4 can be replaced by removing the limiting plate 103. The lower mold 4 with the corresponding shape of the positioning hole 401 can be replaced according to the connector to be produced. This allows the equipment to quickly replace the lower mold 4 with the corresponding shape of the positioning hole 401 according to different types and specifications of connectors, so as to quickly adapt to production. When the mold is worn or damaged, only the limiting plate 103 needs to be removed to replace the lower mold 4. There is no need to carry out large-scale overhaul or replacement of the entire stamping equipment, which reduces the difficulty and cost of mold maintenance.

[0045] Specifically, a punch mounting plate 303 is fixedly connected to the bottom of the die punch 302. The punch mounting plate 303 is fixedly connected to the lower end face of the protective shell 3 by a second mounting bolt 304. When the cylinder 5 drives the protective shell 3 to press down, the protective shell 3 completely covers the lower die 4 to prevent waste from splashing.

[0046] Specifically, the lower die 4 and the die punch 302 can be made of high-hardness, high-wear-resistant die steel materials, such as Cr12MoV, to ensure the stamping accuracy and service life.

[0047] Specifically, the die punch 302 can also be replaced by removing the second mounting bolt 304. The die punch 302 can be replaced according to production needs.

[0048] In this embodiment, the bottom of the die punch 302 is fixedly connected to the punch mounting plate 303. The upper end face of the punch mounting plate 303 is in contact with the lower end face of the protective shell 3 and is fixed by the second mounting bolt 304. The cylinder 5 pneumatically drives the connecting column 501 connected to the output end of the cylinder 5 to descend. The connecting column 501 drives the protective shell 3 to press down. The protective shell 3 slides down along the guide column 6 through the connecting ring 301 until it completely covers the lower die 4. The die punch 302 punches the connector in the positioning hole 401. The protective shell 3 covers the lower die 4 to effectively prevent the phenomenon of waste splashing during the punching process. Waste splashing is an undesirable phenomenon that may occur during the punching process. It may be caused by a variety of factors, such as the punching gap being too large or too small, the punching speed being too fast, and the material hardness being uneven. It may threaten the safety of the operator. The protective shell 3 protects the workers by blocking the flying waste when waste splashes.

[0049] After stamping, the waste material falls through the punch 402 and into the waste discharge outlet 101 through the waste trough 107. A gentle slope can be set below the waste discharge outlet 101 to allow the waste material to slide out automatically for collection, which is convenient for subsequent processing.

[0050] Specifically, the upper end face of the protective shell 3 is fixedly connected to the movable rod 7, the other side of the movable rod 7 is slidably connected inside the fixed plate 2, and the fixed plate 2 has a limiting structure to prevent the movable rod 7 from disengaging.

[0051] Specifically, a tension spring 701 is sleeved on the outer side of the movable rod 7. One end of the tension spring 701 is fixedly connected to the lower end face of the fixed plate 2, and the other end is fixedly connected to the upper end face of the protective shell 3.

[0052] In this embodiment, when the output end of the cylinder 5 drives the connecting column 501 and the protective shell 3 to press down, the top of the movable rod 7 slides downward within the fixed plate 2, and the tension spring 701 outside the movable rod 7 is stretched. During the stamping process, the tension spring 701 remains in a stretched state, continuously accumulating elastic potential energy, providing auxiliary pulling force for the return movement of the protective shell 3 and the die punch 302. After the stamping process is completed, the output end of the cylinder 5 retracts upward. Under the combined action of the pulling force of the cylinder 5 and the rebound force generated by the release of elastic potential energy by the tension spring 701, the protective shell 3 and the connecting column 501 quickly move upward and reset along the guide column 6, reducing the load on the cylinder 5 and providing a guiding effect, thus ensuring the stability of the protective shell 3 during the movement.

[0053] In use, this utility model involves installing a lower mold 4 of the corresponding specifications according to production needs, placing the connector material to be stamped in the positioning hole 401 above the lower mold 4, starting the cylinder 5, and driving the protective shell 3 downward through the output end of the cylinder 5. The protective shell 3 slides downward along the guide post 6 through the connecting ring 301 until it completely covers the lower mold 4. At this time, the mold punch 302 stamps the material in the positioning hole 401, and the material is formed through the punch 402. The waste falls into the waste trough 107. After the stamping is completed, the cylinder 5 drives the protective shell 3 to move upward and reset. The tension spring 701 provides a certain elastic buffer during the upward movement of the protective shell 3, and the movable rod 7 ensures the stability of the movement of the protective shell 3. Finally, the formed connector product is taken out, the waste in the waste trough 107 is cleaned, and one stamping operation is completed.

[0054] All other parts of this utility model not described herein are the same as existing technologies, or are known technologies, or can be implemented using existing technologies, and will not be described in detail here.

[0055] 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.
