Description

Technical Field

[0001] The utility model relates to the technical field of automobile part processing, in particular to a punching device for parts. Background Technique

[0002] Automobile parts are the general term for all parts and components that make up an automobile. They are the foundation of the automobile industry, including everything from engines, transmissions, drive shafts, tires, braking systems, electronic devices to interior trim, seats, windows, etc. Some automobile parts need to be punched during production. When punching automobile parts, if a solid punching die is used, the waste material (the material broken at the punching position) generated by the punching die during punching is likely to remain on the platform and affect the subsequent punching process of the parts. If a hollow punching die is used to punch the parts, after multiple punchings, too much waste material is likely to accumulate inside the punching die and cause blockage, which will in turn affect the subsequent punching operation. Therefore, how to design a punching device that can prevent waste material from affecting the punching of parts during punching and can effectively discharge the waste material continuously has become a problem that needs to be solved by those skilled in the art. Content of the Utility Model

[0003] The purpose of the utility model is to aim at the above deficiencies at present and provide a punching device for parts, which can prevent waste material debris from affecting the punching of parts during punching and can continuously discharge the waste material debris.

[0004] To solve the above technical problems, the utility model adopts the following technical solutions: A punching device for parts, including,

The discharging table is arranged at the moving end of the punching device. The top wall of the guiding block is inclined downward. A guiding hole communicating with the inside of the punching head is vertically formed inside the guiding block. The ejector rod cooperates with the punching head to push the waste material upward and pass through the guiding hole. The inclined surface at the top of the guiding block is used to guide the waste material passing through the guiding hole to be discharged out of the discharging table at the lower end of the inclined surface;

[0010] The punching device is used to drive the punching head to move up and down and punch a hole in the workpiece placed on the workbench.

[0011] Further, a chamfer is provided inside the pipe orifice at the bottom of the punching head.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-4 , the present utility model discloses a component punching device, including a mounting seat 1 and a punching die 4. A punching device 2 and a workbench 3 are installed on the mounting seat 1. The moving end of the punching device 2 faces downward, and the workbench 3 is located at the bottom of the moving end of the punching device 2. The workbench 3 is used to carry the workpiece to be punched. The punching die 4 includes a discharge mechanism connected to the moving end of the punching device 2 and a punching head 42 provided at the bottom of the discharge mechanism. Both the discharge mechanism and the punching head 42 are hollow and communicate with each other. The punching device 2 is used to cooperate with the punching die 4 to punch the workpiece. The punching device 2 can be a hydraulic device. When in use, the workpiece to be punched (automobile component) is placed on the workbench 3, and then the moving end of the punching device 2 is driven to descend. At this time, the punching die 4 also descends and punches the workpiece.

[0025] In one embodiment, a perforation 5 is provided on the workbench 3. The punching head 42 is located directly above the perforation 5. A top-out rod 6 is provided on the mounting seat 1. The top of the top-out rod 6 is located in the perforation 5 and is used to push the waste material inside the punching head 42 into the discharge mechanism when the punching head 42 descends and sleeves outside the top-out rod 6. The discharge mechanism is used to continuously discharge the waste material therein.

[0026] In specific implementation, after the punching head 42 finishes punching the workpiece, the punching device 2 will continue to control the punching head 42 to descend. At this time, the punching head 42 enters into the perforation 5. As the descent continues, the punching head 42 will gradually sleeve onto the ejector rod 6. The top of the ejector rod 6 contacts the waste material inside the punching head 42 and continues to push the waste material upward until it is pushed into the discharge mechanism, and the discharge mechanism will continuously discharge the waste material inside it. Such a design can not only prevent the residual material from contacting the components during punching and affecting the punching effect, but also continuously discharge the residual material, without blocking the inside of the punching head 42, thus facilitating actual use.

[0027] In one embodiment, the discharge mechanism includes a discharge table 41 with a hollow interior. A guide block 43 is installed in the hollow part inside the discharge table 41. The discharge table 41 is installed at the moving end of the punching device 2. The top wall of the guide block 43 is inclined downward. A guide hole communicating with the inside of the punching head 42 is vertically opened inside the guide block 43. The inner diameter of the guide hole is the same as the inner diameter of the punching head 42. The ejector rod 6 cooperates with the punching head 42 to push the waste material and make it pass through the guide hole. The inclined surface at the top of the guide block 43 is used to guide the waste material passing through the guide hole to the lower end of the inclined surface and discharge it outside the discharge table 41. Among them, the punching device 2 is used to drive the punching head 42 to move up and down and punch the workpiece placed on the workbench 3.

[0028] In specific implementation, when the top of the ejector rod 6 contacts the residual material and pushes it into the inside of the discharge table 41, the residual material is located in the guide hole on the guide block 43 at this time. As the punching head 42 continues to move, the ejector rod 6 cooperates with the punching head 42 to push the waste material and make it pass through the guide hole. At this time, the waste material passes through the guide hole and is located on the inclined surface of the guide block 43. The waste material will be guided by the inclined surface of the guide block 43 and discharged outside the discharge table 41. In actual use, a conduit or a guide groove can be installed on the side of the discharge table 41 corresponding to the downward inclined surface of the guide block 43, so that the residual material slides into the conduit or the guide groove and is output in a specified direction, thus facilitating the discharge of the residual material without contacting the workpiece.

[0029] In one embodiment, a chamfer is provided inside the pipe orifice at the bottom of the punching head 42, which is used to make the size of the residual material pushed into the punching head 42 larger than the inner diameter of the punching head 42, and is used to reduce the resistance when punching the workpiece to be punched.

[0030] In the prior art, the chamfer of the punching head 42 is generally set outside the pipe orifice at the bottom of the punching head 42. This is mainly to reduce the resistance during punching of the workpiece and make the size of the waste material generated after punching consistent with the inner diameter of the punching head 42, so that the waste material can enter the inside of the punching head 42 to avoid blocking the punching head 42. However, since the chamfer is on the outside, the edge of the hole punched will bulge to one side and dent on the other side, which requires a lot of time to grind off the bulge during subsequent processes such as grinding; while in this device, the chamfer of the punching head 42 is inside the pipe orifice of the punching head 42. Although this will make the size of the residual material pushed into the punching head 42 slightly larger than the inner diameter of the punching head 42, due to the setting of the ejector rod 6, the waste material can still be pushed into the punching head 42 and the guide hole. And because the waste material is relatively thin (usually a sheet metal part, generally with a thickness not greater than 2 mm), when the waste material contacts the ejector rod 6, it is pushed into a curved shape. After the waste material detaches from the guide hole, it returns to a flat state under its own elastic force, and its size will be slightly larger than the guide hole. In this way, it further avoids the waste material falling back into the guide hole. Therefore, it can only be discharged by the guide block 43 and will not fall back into the guide hole and the punching head 42 repeatedly.

[0031] In one embodiment, a fixed seat 7 is installed on the mounting seat 1, the ejector rod 6 is installed on the fixed seat 7 in a liftable and slidable manner, a driving device 8 is arranged on the mounting seat 1, and the driving device 8 is used to drive the ejector rod 6 to move upward in the punching head 42 when the punching head 42 descends into the through hole 5, and eject the residual material inside the punching head 42 out of the guide hole, and the ejector rod 6 resets when the punching head 42 ascends.

[0032] With such a design, when the punching head 42 finishes punching the workpiece and continues to descend into the through hole 5, the driving device 8 is immediately started to drive the ejector rod 6 to actively rise. Therefore, the ejector rod 6 can be inserted into the punching head 42 more comprehensively and quickly, so that the speed of ejecting the residual material can be further accelerated, and the discharge efficiency of the waste material inside the punching head 42 is improved.

[0033] In one embodiment, the driving device 8 includes a mounting frame 81 installed on the moving end of the punching device 2, a first rack 82 vertically downward is installed on the mounting frame 81, a gear 83 meshing with the first rack 82 is rotatably installed on the mounting seat 1, a second rack 84 meshing with the side of the gear 83 away from the first rack 82 is slidably arranged up and down on the mounting seat 1, and the bottom of the second rack 84 is connected to the ejector rod 6 through a connecting rod.

[0034] With such a design, when the punching device 2 is activated and its moving end descends, the first rack 82 descends synchronously. When the moving end of the punching device 2 descends until the punching head 42 enters into the through hole 5, the first rack 82 immediately contacts and meshes with the gear 83, and the gear 83 starts to rotate. During this process, the second rack 84 meshes with the gear 83 and ascends. The ascending of the second rack 84 drives the ejector rod 6 to ascend, so that the ejector rod 6 quickly enters into the punching head 42 and conducts internal cleaning. When the moving end of the punching device 2 ascends, the first rack 82 ascends synchronously therewith, and cooperates with the gear 83 to make the second rack 84 and the ejector rod 6 continue to descend.

[0035] In one embodiment, a vertically arranged and strip-shaped sliding groove 9 is formed on the inner side wall of the mounting seat 1, and both the mounting frame 81 and the second rack 84 are slidably inserted into the sliding groove 9.

[0036] With such a design, the mounting frame 81 and the second rack 84 can be more stable and reliable during lifting and lowering adjustment.

[0037] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present invention, the directional indications are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly.

[0038] In addition, if there are descriptions such as "first", "second", etc. involved in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features.
