Description

Technical Field

[0001] This utility model relates to the field of punching equipment for parts, and more specifically, to a punching die with a waste removal function. Background Technology

[0002] Punching is a common method for creating holes in thin-walled parts. After punching, the punched-out central sheet is waste material and needs to be removed promptly, otherwise it will affect the punching operation at the next location of the part. The company's existing punching dies do not have a waste removal function, and the waste sheet needs to be removed manually with tools. This not only wastes operation time but also poses production safety risks. Therefore, the company's technical department has carried out an improved design for the punching dies for thin-walled parts to meet the production operation needs of the workshop. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a punching die with a waste removal function. This utility model is reasonably designed and uses the elastic upward movement of the movable seat to lift the waste material pieces. Taking advantage of the light weight of the waste material pieces, the waste removal mechanism forms upward and side airflows, thereby automatically completing the removal of waste material pieces.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A punching die with waste removal function includes a die base, a movable base, and a waste removal mechanism. The bottom of the die base is bolted to a base plate, and the top surface of the die base is recessed downward to form a first cavity. The movable base is adapted to be installed into the first cavity. The movable base is vertically and elastically connected. The waste removal mechanism includes a first air blowing component and a second air blowing component. The first air blowing component can communicate with the air passage of the movable base to form an upward airflow, and the second air blowing component forms a horizontal airflow at the top of the die base.

[0006] Furthermore, a linkage rod is fixedly connected to the bottom surface of the movable seat, and a second cavity is formed by an upward recess on the bottom surface of the mold seat. The linkage rod extends through into the second cavity and is fixedly connected to a limiting plate. A spring is fitted on the outside of the linkage rod, and the spring is disposed in the first cavity. The spring is pressed down by the movable seat.

[0007] Furthermore, the bottom of the linkage rod is connected to a threaded head, and the limiting disc is threadedly connected to the threaded head.

[0008] Furthermore, the maximum rising height of the movable seat is determined by the limiting plate, and the movable seat can rise to be flush with the top surface of the mold base.

[0009] Furthermore, the first air blowing assembly includes a first air supply element installed on the outer side of the mold base. The mold base has a first ventilation channel arranged horizontally. The outlet of the first air supply element is connected to the first ventilation channel. The movable seat has a second ventilation channel. The second ventilation channel extends vertically upward and penetrates the top surface of the movable seat. When the movable seat rises to the upper limit position, the first ventilation channel and the second ventilation channel are connected accordingly.

[0010] Furthermore, the second ventilation duct has a narrowed air outlet on the top surface of the movable seat.

[0011] Furthermore, the second air blowing assembly includes a bracket and a second air supply element. The bracket is fixedly installed on the side wall of the mold base, the second air supply element is vertically installed on the bracket, and the outlet of the second air supply element is arranged horizontally.

[0012] Furthermore, a conical shroud is installed at the outlet connection of the second air supply element.

[0013] Furthermore, a switch is installed inside the second cavity. The switch is partially embedded and blocks the upward path of the limiting plate. The switch is a momentary pressure switch, and the activation of the first and second air blowing components is controlled by triggering the switch.

[0014] The beneficial effects of this utility model are:

[0015] This utility model is reasonably designed. It uses the elastic upward movement of the movable seat to lift the waste material pieces. Taking advantage of the light weight of the waste material pieces, the waste material removal mechanism creates upward and lateral airflows, thereby automatically completing the removal of waste material pieces.

Detailed Implementation

[0018] 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.

[0019] like Figure 1 The punching die shown includes a die base 1, a movable base 3, and a waste removal mechanism 4. A base plate 2 is bolted to the bottom of the die base 1. The base plate 2 has bolt holes, allowing the entire punching die to be mounted on a punching workbench. The top surface of the die base 1 is recessed downwards to form a first cavity 11, which serves as the chamber for inserting a punch (the punch is an important component of the punching equipment; it can be raised and lowered vertically, and when it descends into the first cavity 11, it can cut holes in thin-walled parts). The punching equipment (which is existing technology and is not shown in the diagram, but only briefly described here) is fitted into the first cavity 11. The movable seat 3 is vertically and elastically connected, and plays a role in punching holes with the punch. When the punch descends rapidly, the movable seat 3 can also descend and retract accordingly without affecting the descent of the punch. However, it can cooperate with the punch to cut the surface of thin-walled parts to make holes. The cut-off waste material is located at the top of the movable seat 3. As the punch rises, the movable seat 3 also elastically returns to its original position. Waste sheets are lifted up. Currently, workers use tools to quickly remove the waste sheets from the mold, but this wastes time and poses certain operational and installation risks. Therefore, this invention designs and adds a waste sheet removal mechanism 4 to solve the problem of automatic removal of waste sheets. The waste sheet removal mechanism 4 includes a first blowing component 41 and a second blowing component 42. The first blowing component 41 is connected to the air passage of the movable seat 3 to form an upward airflow. The second blowing component 42 forms a horizontal airflow at the top of the mold seat 1. Since the thin-walled waste sheets are very light, this invention utilizes this characteristic to design an upward airflow to lift the waste sheets, and then uses a horizontal airflow to blow them down laterally. The direction of the blowing can be used to place a waste collection trough to collect the waste sheets. The automatic removal of waste sheets in this invention is performed automatically when a single punching operation is completed, and can quickly remove waste sheets without manual intervention. This invention has good practical effects, improving production efficiency and ensuring production safety.

[0020] like Figure 1As shown, this utility model has a linkage rod 31 fixedly connected to the bottom surface of the movable seat 3. The linkage rod 31 moves together with the movable seat 3. The bottom surface of the mold seat 1 is recessed upward to form a second cavity 12. The linkage rod 31 extends through into the second cavity 12 and is fixedly connected to a limit plate 33. A spring 32 is fitted on the outside of the linkage rod 31. The spring 32 is located in the first cavity 11 and is pressed by the movable seat 3. The spring 32 provides elastic lifting force to the movable seat 3. During the punching operation, the spring 32 is compressed. When the punching is completed, the movable seat 3 rises and returns to its original position under the elastic lifting force of the spring 32 due to the rise of the punch. The depth of the second cavity 12 must meet the descent stroke of the movable seat 3. The design of the second cavity 12 is to facilitate the installation of the limiting plate 33 and other components. The linkage rod 31 is installed from top to bottom, and the bottom of the linkage rod 31 is connected to the threaded column head 311. The limiting plate 33 is installed from bottom to top and is threadedly connected to the threaded column head 311. The maximum rising height of the movable seat 3 is determined by the limiting plate 33. When the movable seat 3 is at its rising limit, the movable seat 3 is flush with the top surface of the mold base 1. This will not affect the movement of the thin-walled parts on the mold base 1. The rising limit of the movable seat 3 occurs when the limiting plate 33 abuts against the top surface of the second cavity 12.

[0021] like Figure 1As shown, the first air blowing assembly 41 includes a first air supply element 411 installed on the outer side of the mold base 1. The first air supply element 411 is a valve body that controls the airflow. The first air supply element 411 has an inlet and an outlet. The inlet of the first air supply element 411 is connected to an external air source (providing the air required for blowing). A first ventilation channel 13 is provided on the mold base 1 in a horizontal direction. The outlet of the first air supply element 411 is connected to the first ventilation channel 13. When the first air supply element 411 is opened, air first enters the first ventilation channel 13. A second ventilation channel 34 is provided on the movable seat 3. The second ventilation channel 34 extends vertically upward and penetrates the top surface of the movable seat 3. When the movable seat 3 rises to the upper limit position, the first ventilation channel 13 and the second ventilation channel 34 are correspondingly connected. The movable seat 3 rising to the upper limit position indicates that the punching is completed and the waste material is pushed to the highest position. At this time, the first ventilation channel 13 and the second ventilation channel 34 are correspondingly connected, allowing airflow to enter the second ventilation channel 34 and exit from the movable seat 3. The top surface is blown out to lift up the waste material pieces. The second ventilation duct 34 of this utility model has an air outlet 341 with a reduced opening at the top surface of the movable seat 3. This design increases the airflow velocity by reducing the cross-section, so as to better lift up the waste material pieces. The second blowing assembly 42 of this utility model includes a bracket 421 and a second air supply element 422. The bracket 421 is fixedly installed on the side wall of the mold seat 1, and the second air supply element 422 is vertically installed on the bracket 421. The second air supply element 422 is also a valve body for controlling airflow. The second air supply element 422 also has an inlet and an outlet. The inlet of the second air supply element 422 is also connected to an external air source (to provide the air required for blowing). The outlet of the second air supply element 422 is arranged horizontally. In order to increase the air receiving area, a conical wind hood 423 is connected and installed at the outlet of the second air supply element 422. The conical wind hood 423 can increase the air outlet area and can smoothly blow down the waste material pieces lifted by the upward airflow laterally.

[0022] In this invention, controlling the activation timing of the first blowing assembly 41 and the second blowing assembly 42 is also crucial. The first blowing assembly 41 and the second blowing assembly 42 should only be activated after punching is complete and the movable seat 3 has raised the waste material sheet to its highest position. Therefore, as follows... Figure 1As shown, a switch 43 is installed in the second cavity 12. The switch 43 is installed at the top of the second cavity 12 and is partially embedded. The switch 43 can be deformed by pressure and triggered. The present invention designs the switch 43 to block the rising path of the limiting plate 33. The switch 43 is a momentary pressing switch. After the limiting plate 33 reaches the rising limit, it triggers the switch 43 and presses the switch 43 completely into the mounting hole (at this time, the punching is finished and the movable seat 3 raises the material waste sheet to the highest position). The switch 43 is momentary controlled. Each pressing can only start the first air blowing component 41 and the second air blowing component 42 once. The present invention uses the trigger of the switch 43 to momentary control the simultaneous activation of the first air blowing component 41 and the second air blowing component 42. In actual use, it was found that the ventilation activation time of the first air supply element 411 and the second air supply element 422 can be set within 1 second, which is sufficient for automatic removal of material waste sheets.
