Description

Technical Field

[0001] This utility model relates to the field of stamping device technology, specifically a stamping device for the production of machine tool parts that is easy to handle. Background Technology

[0002] A stamping device is a special process equipment used in cold stamping to process metal or non-metal materials into parts. Stamping is a pressure processing method that uses a die mounted on a press to apply pressure to the material at room temperature, causing it to separate or plastically deform, thereby obtaining the desired parts. Stamping devices are frequently used in the production of machine tool parts.

[0003] As disclosed in the patent announcement CN222343960U, a stamping device for easy-to-handle machine tool parts production includes a base plate. Four columns are fixedly connected to the top of the base plate, and a worktable is fixedly connected to one end of each column. A turntable is rotatably connected to the worktable, which has four limiting holes. The turntable has four stamping holes of different diameters, and a first pulley is fixedly connected to the bottom of the turntable. The beneficial effects of this invention are as follows: by setting up stamping holes, a belt, limiting rods, tension springs, threaded rods, punches, and limiting holes, the punch can be quickly replaced, and the stamping holes can be quickly switched. Furthermore, the four limiting holes correspond one-to-one with the four stamping holes. Inserting the limiting rod into the limiting hole aligns the center of the stamping hole with the center of the punch, eliminating the need for multiple adjustments to the turntable position. This simplifies operation, facilitates stamping holes of different diameters, and improves work efficiency.

[0004] Although the aforementioned patent features a rotatable and adjustable turntable, it uses belt drive to rotate the turntable to switch the punching holes. Since the belt and pulley rely on friction transmission, there is a risk of slippage, which may cause the actual rotation angle of the turntable to differ from the theoretical angle, affecting the alignment accuracy of the punching holes and the punch.

[0026] 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.

[0027] like Figure 1-6 As shown, this utility model provides a technical solution:

[0028] A stamping device for producing machine tool parts that is easy to handle includes a worktable 1 with a transverse groove 2 penetrating its center. A stamping table 3 is slidably connected inside the transverse groove 2. A horizontal adjustment mechanism is provided between the stamping table 3 and the worktable 1. The horizontal adjustment mechanism includes sliding grooves 6 symmetrically formed on the inner walls of both sides of the transverse groove 2, and sliders 7 symmetrically fixedly connected to the outer walls of both sides of the stamping table 3. The sliders 7 are horizontally slidably connected to the sliding grooves 6. The horizontal adjustment mechanism also includes a rack 8 fixedly connected to the bottom right side of the stamping table 3, and shaft brackets 9 symmetrically fixedly connected to the bottom left and right sides of the worktable 1. The two shaft brackets 9 are connected to each other. A worm gear 10 is rotatably connected to the shaft frame 9 via a bearing. One end of the worm gear 10 extends to the outside of the shaft frame 9 and is fixedly connected to a handwheel 11. A worm wheel 12, meshing with the worm gear 10, is rotatably connected to the bottom center of the worktable 1 via a bearing. The worm wheel 12 extends downward and is fixedly connected to a gear 13 that meshes with the rack 8. Several punching holes 14 are arranged side by side and equidistant from each other on the stamping table 3. The diameter of the punching holes 14 decreases sequentially from left to right. Positioning marks 15 are evenly distributed on the left side of the punching holes 14 on the stamping table 3. Positioning marks 15 are arranged on the left side of the horizontal groove 2 on the worktable 1. Positioning mark 15 is matched with positioning mark 16. When positioning mark 15 and positioning mark 16 are aligned, the center line of the corresponding punching hole 14 coincides with the axis of the punching head 18. Support frame 4 is fixedly connected to the upper middle part of the worktable 1. A punching mechanism is provided on support frame 4. The punching mechanism includes a hydraulic cylinder 17 vertically fixedly connected to the middle of the top of support frame 4, and a punching head 18 detachably installed on the output shaft end of hydraulic cylinder 17. Discharge hopper 5 is fixedly connected to the lower middle part of the front of worktable 1. A material picking mechanism is provided between discharge hopper 5 and worktable 1. The material picking mechanism includes an opening mechanism. A lifting groove 19 is located in the middle of the left side of the workbench 1, and a fixing block 20 is fixedly connected to the middle of the inner wall of the lifting groove 19. Vertical guide bars 21 are fixedly connected to both sides of the front end of the lifting groove 19. A baffle 22 is slidably connected between the two guide bars 21. An operating protrusion 23 is fixedly connected to the middle of the top front of the baffle 22. A locking screw 24 is threadedly connected to the top back of the baffle 22. A threaded hole that mates with the locking screw 24 is opened in the middle of the fixing block 20. The lower end of the baffle 22 abuts against the upper front end of the hopper 5. The right side of the hopper 5 is located below the middle of the transverse groove 2.

[0029] In this embodiment, the meshing transmission of the worm gear 10 and the worm wheel 12, combined with the guiding structure of the slider 7 and the groove 6, enables precise multi-position adjustment of the stamping table 3, solving the technical problem of insufficient positioning accuracy of the traditional belt drive mechanism. This allows the stamping holes 14 of different diameters to be accurately aligned with the stamping head 18, meeting diverse processing needs.

[0030] Furthermore, by using the lifting baffle 22 in conjunction with the unloading hopper 5 and the fastening structure of the locking screw 24, the centralized collection function of batch stamped parts is realized, which solves the technical problem of low efficiency caused by the need for traditional equipment to pick up materials one by one, and improves the convenience of unloading operation.

[0031] Working principle: The operator first selects a matching stamping head 18 according to the processing requirements and installs it on the output shaft end of the hydraulic cylinder 17. The handwheel 11 drives the worm gear 10 to rotate, which in turn drives the meshing worm wheel 12 to rotate. The worm wheel 12 drives the rack 8 to move horizontally through the coaxially connected gear 13, thereby causing the stamping table 3 to slide within the transverse groove 2 of the worktable 1. The movement stability is ensured by the cooperation between the slider 7 and the slide groove 6. When the stamping table 3 moves to the required position, the positioning mark 15 on the stamping table 3 is observed to align with the positioning mark 16 on the worktable 1. At this time, the center line of the corresponding stamping hole 14 coincides with the axis of the stamping head 18. After precise positioning, the external feeding mechanism conveys the strip steel plate to the stamping head 18. The pressure table 3 is aligned with the area to be processed and the stamping hole 14 is aligned. The hydraulic cylinder 17 is activated to drive the stamping head 18 to press down and complete the stamping operation. The stamped workpiece is temporarily stored in the unloading hopper 5 below the stamping hole 14. After the batch stamping operation is completed, the operator first loosens the locking screw 24 to release the locking block 20 on the baffle 22, and then pulls the operating protrusion 23 upward to make the baffle 22 rise along the guide bar 21 to open the unloading channel, so that the accumulated stamped products slide out of the unloading hopper 5 for collection. After the unloading is completed, the baffle 22 is reset and the locking screw 24 is tightened to achieve a seal. When it is necessary to change the stamping hole diameter or the stamping head 18, the above adjustment process is repeated so that the stamping hole 14 of different diameters is aligned with the corresponding stamping head 18.

[0032] It should be noted that in the specific implementation of this technical solution, the stamping head 18 can be configured with conventional detachable connection structures in the prior art (such as threaded connections, quick-release pins, or flange connections). Although such detachable connection structures are not described in detail in the technical solution, they are additional components that can be conventionally selected by those skilled in the art according to actual stamping processing needs. Their installation methods and working principles follow well-known technologies in the field and do not affect the implementation of the core innovation of this solution. In practical applications, the stamping head 18 is mainly used for stamping processing of workpieces of different specifications, but its specific type and connection method can be adjusted according to production requirements, all of which fall within the reasonable extension scope of this technical solution.

[0033] In another specific embodiment of this technical solution, positioning mark 15 and positioning mark 2 16 can be installed and fixed using conventional methods in the prior art (such as countersunk screw fastening, surface groove embedding, or laser engraving). Although such installation methods are not described in detail in the technical solution, they are fixing means that can be conventionally selected by those skilled in the art based on actual installation needs.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
