Traditional operations require one worker to clamp the forging with pliers, and another worker to place the punch seat on the lower forging platform with pliers. The forging is then placed on the punch seat, and finally the punch column is placed on the forging. The ram of the forging press presses down, punching through the forging through the punch column to complete the hole.

[0003] In an existing forging production punching device, the center point is easily deviated when punching holes in forgings, resulting in a deviation in the punching size. Utility Model Content

[0004] In order to address the deficiencies of the prior art, the present invention provides a punching device for forging production, which solves the problem that the center point is easily deviated during forging punching, resulting in a deviation in the punching size.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a punching device for forging production, comprising a receiving base plate, wherein limit assemblies for limiting punching forgings are symmetrically mounted on the left and right ends of the receiving base plate, and a punching member is provided on the upper end of the limit assembly so as to slide within the range of the receiving base plate;

[0008] In one embodiment, a receiving groove is provided on the opposing structures of the limiting substrate and the receiving substrate, and the receiving grooves of the two symmetrically arranged limiting substrates form an accommodating inner cavity for accommodating the punched forging;

[0009] The plug-in hole is opened above the accommodating groove and a positioning sleeve is installed on the structure through which the top column passes. The inner diameter of the positioning sleeve is adapted to the outer diameter of the plug-in column.

[0010] In one embodiment, the bottom diameter of the top column is larger than the width of the accommodating groove, and a cutout adapted to the width of the accommodating groove is opened on the bottom surface of the top column.

[0011] In one embodiment, the top post is cylindrical and has a plurality of equally spaced sockets formed in a longitudinal direction thereon, the diameter of the sockets being no less than the diameter of the plug-in post, a sleeve is sleeved on the structure of the top post with the sockets formed thereon, the sleeve is placed on the upper end of the limiting base plate, and the sleeve is provided with slots adapted to the number of top posts, and an L-shaped convex plate is installed on the side wall of the slot;

[0016] Beneficial effects:

[0017] In the technical solution disclosed by the present utility model, a limiting component arranged on the receiving base plate is used to limit the forging to be punched within the working range of the drill bit and reduce the amount of movement generated by the drill bit when it is working. Furthermore, the forging to be punched is fixed and restricted to the top surface of the receiving base plate and fits the receiving base plate, thereby reducing the vibration of the forging to be punched caused by its own suspension when the drill bit is working, thereby enhancing the limiting effect.

[0018] By providing a cutout on the bottom surface of the top column that matches the width of the accommodating groove, the utility model enables the accommodating cavity established by the two relative limiting substrates to change in size after the wall of the accommodating groove is worn after several cycles of use. At this time, the top column is always in an inconvenient position, and the side wall of the cutout can abut against the forging to be punched, so as to reduce the problem of the forging shaking left and right in the accommodating cavity caused by the wear of the accommodating cavity, thereby enhancing the limiting effect and extending the service life.

DETAILED DESCRIPTION

[0024] The following will describe the implementation methods of the present application in detail with reference to the accompanying drawings and examples, so that the implementation process of how the present application applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0025] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0026] Figure 1-Figure 3 This is an embodiment of the present invention. The specific problem addressed by this embodiment is that the traditional operation requires one worker to use a clamp to pick up the forging, and another worker to use a clamp to place the punching seat on the lower forging platform, and then place the forging on the punching seat, and finally place the punching column on the forging. The ram of the forging press presses down, and the forging is punched through by the punching column to complete the hole. The existing forging production punching device is easy to deviate from the center point when punching the forging, resulting in a deviation in the punching size. This solution proposes a forging production punching device, which uses a limiting component 2 set on a receiving base plate 1 to limit the forging to be punched within the working range of the drill bit 32 and reduce the amount of movement generated by the drill bit 32 when it is working. Furthermore, the forging to be punched is fixed to the top surface of the receiving base plate 1 and is in contact with the receiving base plate 1, thereby reducing the vibration of the forging to be punched due to its own suspension when the drill bit 32 is working, thereby enhancing the limiting effect.

[0027] The punching device for forging production described in this scheme specifically includes a receiving base plate 1, and a limiting component 2 for limiting punching forgings is symmetrically installed on the left and right ends of the receiving base plate 1. The upper end of the limiting component 2 is provided with a punching member 3 that slides within the range of the receiving base plate. The punching member 3 includes a sliding component 31 installed at both ends of the limiting base plate 21. The sliding component 31 installs a drill bit 32 between the two limiting base plates 21. The drill bit 32 can be suitable for existing common drilling drill bits 32. The sliding component 31 includes a support rod that slides on the limiting base plate 21 through a screw rod. A connecting rod connecting the drill bit 32 is installed between the two support rods. The connecting rod slides on the support rod through a screw drive. The connecting rod slides up and down on the support rod. The connecting rod and the drill bit 32 slide on the connecting rod through the screw rod to cover the position where the forging to be punched needs to be punched. A ramp plate 4 with an inclined top surface is installed on the structure that supports the substrate 1 in the loading direction. The end surface position of the ramp plate 4 is smaller than the end surface position of the limiting substrate 21, which is convenient for loading.

[0028] The limiting assembly 2 includes a limiting base plate 21 whose length is greater than that of the supporting base plate 1. The upper end of the limiting base plate 21 is provided with a plurality of top columns 22 for longitudinally limiting the movement range of the punching forging in the limiting base plate 21. A plug-in plate 23 is provided on the side wall of the limiting base plate 21 and is vertically plugged into the top columns 22. The plug-in plate 23 includes a plug-in plate 231 and a plug-in column 232 installed on the plug-in plate 231. A group of plug-in holes 24 adapted to the plug-in columns 232 are opened on the limiting base plate 21, and the plug-in holes 24 pass through the limiting base plate 21.

[0029] Receiving slots 25 are defined on the opposing structures of the limiting base plate 21 and the receiving base plate 1. The symmetrically positioned receiving slots 25 of the two limiting base plates 21 create an internal cavity for accommodating the punched forging. The insertion hole 24 is located above the receiving slot 25 and is mounted on the structure through which the top post 22 extends. A positioning sleeve 26 is installed, and the inner diameter of the positioning sleeve 26 matches the outer diameter of the insertion post 232. The bottom diameter of the top post 22 is larger than the width of the receiving slot 25, and a notch 27 is defined on the bottom surface of the top post 22 to match the width of the receiving slot 25. After the walls of the receiving slot 25 wear after several cycles of use, the dimensional changes of the receiving cavity established by the two opposing limiting base plates 21 occur. At this time, the top post 22 is positioned in an inconvenient manner, and the sidewalls of its notch 27 can abut against the punched forging to reduce the problem of the forging swaying inside the receiving cavity due to wear, thereby enhancing the limiting effect and extending the service life.

[0030] The top column 22 is a columnar body and has a number of equally spaced sockets opened in the longitudinal direction. The diameter of the socket is not less than the diameter of the plug-in column 232. A sleeve 28 is sleeved on the structure with the socket of the top column 22. The sleeve 28 is placed on the upper end of the limiting base plate 21. The sleeve 28 is provided with slots adapted to the number of the top columns 22. An L-shaped convex plate 29 is installed on the side wall of the slot. A groove 210 is opened on the side wall of the top column 22 at the position adapted to the convex plate. The lower end of the groove 210 extends to the bottom surface of the top column 22 and is connected to the groove 210 through the convex plate 29.

[0031] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. In addition, the present invention is mainly used to protect mechanical devices, so the control method and circuit connection are no longer explained in detail in the present invention.

[0032] It should be noted that, in this article, the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements that are inherent to such process, method, article or apparatus.

[0033] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
