Description

Technical Field

[0001] This application relates to the field of stamping technology, specifically to a multi-hole stamping positioning device for injection equipment. Background Technology

[0002] Currently, the conventional method for multi-hole stamping of angle steel workpieces is to use a conventional press in conjunction with a single-hole stamping die. During the stamping operation, for each hole to be processed, the operator needs to individually install a corresponding positioning device on the workpiece, or adjust the same positioning device multiple times. Specifically, when processing one hole, the angle steel workpiece to be punched must first be installed and fixed in place using a positioning device, and then the press is started to complete the stamping of that hole. When processing the next hole, the previous positioning device must be removed, and a positioning device for the new hole must be installed, then the workpiece is fixed again and stamped. This cycle is repeated until all holes are processed. The entire processing relies on the operator manually performing the positioning, clamping, and stamping operations for each step.

[0003] In the aforementioned traditional stamping operations, each hole requires an independent installation (or adjustment) of a positioning device and a workpiece fixing process, resulting in a lengthy processing time, repetitive and tedious steps, and high labor intensity. Furthermore, the repeated positioning and clamping processes inevitably introduce positioning errors. These small deviations accumulate as the number of holes increases, making it difficult to accurately guarantee the relative dimensions (such as hole spacing) between multiple holes, leading to poor consistency. This lack of precision directly affects the assembly quality and reliability of the punched angle steel workpiece with other components.

[0018] Unless otherwise specified, the unit modules, components, structures, mechanisms, or sensors involved in the following embodiments are all commercially available products.

[0019] To better understand the technical solution of this application, the above technical solution will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] To address the technical problem of low processing efficiency and poor accuracy caused by the need for multiple replacements of the positioning device during the existing multi-hole stamping of angle steel, this embodiment discloses a positioning device for multi-hole stamping of angle steel in a filling equipment, such as... Figure 1 As shown, it includes a punching base plate, a punching guide plate, and a punching positioning assembly, wherein the punching base plate provides an installation platform for the punching guide plate and the punching positioning assembly.

[0021] like Figure 1 As shown, in this embodiment, after the worker determines the positions of the angle steel workpiece 1 to be punched, each with the same hole structure on the same straight line, the angle steel workpiece 1 is placed on the punching and shearing machine workbench 2 for punching. To ensure the stable placement of the angle steel workpiece 1 and improve processing safety, a punching base plate 3 is fixed at the corresponding position on the punching and shearing machine workbench 2. The angle steel workpiece 1 placed on the punching base plate 3 must correspond to the punching die 5 of the punching and shearing machine. After the punching and shearing machine punches one position of the angle steel workpiece 1, the angle steel workpiece 1 needs to be moved along the length of the punching base plate 3 to position the next position to be punched on the same straight line. Therefore, a punching guide plate 4 is fixed on the punching base plate 3 to limit the position of the angle steel workpiece 1 in the direction perpendicular to the length of the punching base plate 3, ensuring the positioning of each position to be punched on the angle steel workpiece 1 and the punching die 5 in the direction perpendicular to the length of the punching base plate 3. Meanwhile, as the angle steel workpiece 1 to be punched moves horizontally under the guidance of the punching guide plate 4, it is also necessary to position and punch each hole to be processed relative to the punching die 5 of the punching and shearing machine along the length of the punching base plate. Therefore, a punching positioning component is provided on the punching base plate 3 to limit the positioning of the angle steel workpiece 1 to be punched along the length of the punching base plate 3, so as to ensure the positioning of each hole to be processed on the angle steel workpiece 1 relative to the punching die 5 along the length of the punching base plate 3. Through the setting of the punching guide plate 4 and the punching positioning component, the precise positioning of the angle steel workpiece 1 to be punched relative to the punching die 5 along the length of the punching base plate 3 and perpendicular to the length of the punching base plate 3 is achieved. This also greatly reduces the positioning difficulty of each hole to be processed on the angle steel workpiece 1 and improves the working efficiency when processing the same hole structure on the same straight line.

[0022] The angle steel workpiece 1 to be punched is placed on the worktable 2 of the punching and shearing machine via the punching base plate 3. Specifically, as shown... Figure 2 , 3As shown, in this embodiment, the punching base plate 3 is an L-shaped plate, which includes a horizontal plate 31 fixed horizontally to the top surface of the punching and shearing machine workbench, and a vertical plate 32 perpendicular to the horizontal plate and connected to the side of the punching and shearing machine workbench by two bolts 8. Preferably, in order to stably place the angle steel workpiece 1 to be punched on the punching base plate 3 for moving and positioning, the length of the punching base plate 3 is greater than the length of the angle steel workpiece 1 to be punched. However, since the punching die 5 of the punching and shearing machine is prone to interference with the punching base plate 3 when punching the angle steel workpiece 1, causing damage to the punching die 5, in this embodiment, a hole 6 matching the cross-sectional contour of the punching die is opened on the punching base plate 3 corresponding to the punching die 5. The hole 6 is vertically collinear with the punching die 5 to improve the safety during punching.

[0023] The angle steel workpiece 1 to be punched is positioned on the punching base plate 3 by the punching guide plate 4, and the punching die 5 is positioned in a direction perpendicular to the length of the punching base plate 3. Specifically, as follows: Figure 2 , 3 As shown, the punching guide plate 4 includes a base plate 41 fixed to a horizontal plate 31 by four welded positioning pins 10, and a side plate 42 arranged along the length of the horizontal plate 31 and perpendicular to the base plate 41 for contacting one side of the angle steel workpiece 1 to be punched. Considering the stability of the punching guide plate 4, in this embodiment, the punching guide plate 4 is a U-shaped plate, which also includes another rigid side plate 43 perpendicular to the base plate 41 and located at the edge of the punching base plate 3. The base plate 41 and the other rigid side plate 43 have the same length as the punching base plate 3, and the length of the side plate 42 is only greater than the diameter of the hole 6. In addition, when the punching machine processes the punching, in order to prevent the punching die 5 of the punching machine from interfering with the side plate 42 of the punching guide plate 3, the hole 6 passes through both the punching base plate 3 and the side plate 42 to ensure safe processing. To enhance the installation of the punching base plate 3 and the punching guide plate 4, preferably, the punching base plate 3 is positioned on the punching guide plate 4 by welding positioning pins 10, and the horizontal plate 31 and the base plate 41 are fixed by welding; at the same time, the punching base plate 3 and the punching guide plate 4 are fixedly installed on the punching and shearing machine worktable 2 by two fixing pins 9 that pass through the horizontal plate 31 and the base plate 41.

[0024] Therefore, under the limiting guidance of the punching guide plate 3, the angle steel workpiece 1 to be punched is positioned so that each hole to be processed corresponds one-to-one with the punching die 5 of the punching and shearing machine through the punching positioning assembly. Specifically, as shown in the figure... Figure 3As shown, the punching positioning assembly includes a plurality of elastic positioning pins 7 arranged along the length of the punching base plate 3 and corresponding to the end of the angle steel workpiece 1 to be punched. The spacing between the plurality of elastic positioning pins 7 matches the spacing between the holes to be processed on the angle steel workpiece 1. Thus, the end of the angle steel workpiece 1 to be punched abuts against the elastic positioning pins 7 at different positions to achieve positioning of each hole to be processed and the punching die 5 along the length of the punching base plate 3. However, when the angle steel workpiece 1 to be punched is placed on the punching base plate 3 for end positioning, some elastic positioning pins may interfere with the angle steel workpiece 1. Therefore, in this embodiment, the punching base plate 3 is provided with pin slots corresponding to the positions of the elastic positioning pins 7. Specifically, the elastic positioning pin 7 includes a housing 71 fixed to the bottom of the horizontal plate 31 and corresponding to the pin slot, a positioning pin 72 slidably disposed in the housing 71 and with one end extending upwards from the punching base plate 3 to contact the end of the angle steel workpiece 1 to be punched, and a spring 73 sleeved on the other end of the positioning pin 72 located inside the housing 71. Preferably, the elastic positioning pins 7 can be symmetrically distributed on the punching base plate 3 with the hole 6 as the center, so that the angle steel workpiece 1 to be punched is positioned with the elastic positioning pins 7 on the left and right sides of the punching base plate 3 respectively, so that hole structures with the same spacing are processed on the left and right sides of the angle steel workpiece 1 to be punched. The worker presses the angle steel workpiece 1 to be punched onto the punching base plate 3 and starts punching from one end. Each time, the end of the angle steel workpiece 1 is in contact with a positioning pin 72 of an elastic positioning pin 7. The elastic positioning pins 7 that interfere with the angle steel workpiece 1 are compressed and their positioning pins 72 are retracted into the housing 71. When there is no interference with the angle steel workpiece 1, the positioning pins 72 automatically extend out of the punching base plate 3 by the elastic force of the spring 73. Thus, under the guidance of the punching guide plate 4, the angle steel workpiece 1 is processed sequentially for each hole on the same straight line until all holes are processed.

[0025] In some other embodiments, considering that one end of the angle steel workpiece 1 to be punched is positioned by abutting the elastic positioning pin 7, while the other end needs to be pressed by hand by the worker, in order to reduce manpower consumption, the elastic positioning pin 7 in this example can abut against both ends of the angle steel workpiece 1 to be punched, so that the angle steel workpiece 1 to be punched is clamped on the punching clamping plate 3, without the need for the worker to hold it, thereby realizing the positioning of the hole to be processed and the punching mold 5, reducing errors in manual operation, and improving safety.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of this application.
