Description

Technical Field

[0001] This utility model relates to the field of punch press dies, and in particular to a structure for automated production of multi-station dies. Background Technology

[0002] In the rectangular sheet metal stamping process, this positioning device is cleverly integrated into the lower die. Its core function is to achieve precise positioning during the sheet metal unloading stage, ensuring the consistency of the material's initial position. However, existing automated production lines commonly use robotic arms for loading and unloading operations, but a key technical bottleneck exists: when the ejector pushes out the stamped workpiece at high speed, the instantaneous separation of the workpiece from the die and the inertia often cause the workpiece to jump or shift within the die cavity. This dynamic displacement causes a deviation between the robotic arm's gripping point and the theoretical position, resulting in inaccurate positioning of the workpiece in subsequent stations such as bending, welding, or inspection, ultimately leading to dimensional errors or assembly failures. Utility Model Content

[0003] The purpose of this utility model is to provide a structure for automated production of multi-station molds to solve the technical problem of inaccurate gripping position of workpieces after discharge.

[0004] To solve the above-mentioned technical problems, this utility model provides a structure for automated production of multi-station molds, including a positioning block set on the lower template, an ejector set on the lower template, the ejector including a cylinder and an ejector rod set on the piston rod of the cylinder, and a magnet is also provided on the side of the ejector rod facing the workpiece.

[0005] In a preferred embodiment, four positioning blocks are provided and arranged symmetrically, and a right-angle groove is provided on the side of the positioning block facing the workpiece.

[0006] In the preferred embodiment, wear-resistant plates are provided on both sides of the right-angle groove.

[0007] In a preferred embodiment, a floating device is further provided on the lower template. The floating device includes a base, a first guide hole in the base, a floating rod that moves along the direction of the first guide hole in the first guide hole, a spring in the first guide hole below the floating rod, a connecting rod on the floating rod, and the positioning block is mounted on the connecting rod.

[0008] In a preferred embodiment, a material detector for detecting the presence or absence of a workpiece is also provided on the lower template.

[0009] In a preferred embodiment, an annular plate is provided above the first guide hole, and a second guide hole with a smaller size than the first guide hole is provided on the annular plate. The floating rod moves within the second guide hole, and a guide block matching the first guide hole is provided below the floating rod. The spring is located below the guide block.

[0010] The beneficial effects of this utility model are as follows: by setting a magnet on the side of the push rod facing the workpiece, the push rod can hold the workpiece in place during the upward lifting process, preventing the workpiece from jumping during the lifting process and avoiding affecting the final positioning of the workpiece, thereby affecting the robot arm's gripping of the workpiece in the next process; furthermore, by setting a ring plate, the movement of the spring within the first guide hole can be restricted, preventing the spring from coming out.

[0013] In the description of this invention, it should be understood that if terms such as "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0014] Example 1: Please see Figure 1-5As shown, this application provides a technical solution: a structure for automated production of multi-station molds, including a positioning block 11 on the lower template and an ejector 2 on the lower template. The ejector 2 includes a cylinder 21 and an ejector rod 22 on the piston rod of the cylinder 21. A magnet 23 is also provided on the side of the ejector rod 22 facing the workpiece 101. Multiple ejectors 2 can be provided according to the workpiece; in this embodiment, four can be symmetrically arranged.

[0015] With the above structure, the workpiece can be directly placed on the positioning block 11 on the lower template for positioning. After the workpiece completes the stamping action, the ejector 2 below the workpiece lifts the workpiece. By setting the magnet 23, the magnet 23 can hold the workpiece. In this way, the position of the workpiece and the relative position of the ejector 22 can remain unchanged during the lifting process. Thus, the positioning position of the workpiece can also remain unchanged, which makes it convenient for the robot arm in the next process to grab the workpiece from the positioning position.

[0016] In a preferred embodiment, four positioning blocks 11 are provided and arranged symmetrically, and a right-angle groove 111 is provided on the side of the positioning block 11 facing the workpiece 101.

[0017] With the above structure, the four positioning blocks 11 and the corresponding right-angle slots 111 can form a rectangular placement space, which makes it convenient to place the rectangular workpiece in the space enclosed by the positioning blocks 11 and realize the lateral positioning of the workpiece 11.

[0018] In the preferred embodiment, wear-resistant plates 35 are provided on both sides of the right-angle groove 111.

[0019] With the above structure, since the workpiece is frequently placed there, there is a lot of friction between the workpiece and the right-angle groove 111. The wear-resistant plate 35 can improve the wear resistance of the right-angle groove 111. The wear-resistant plate 35 is mainly composed of low carbon steel plate and alloy wear-resistant layer, such as high manganese steel plate.

[0020] In a preferred embodiment, a floating device 3 is also provided on the lower template. The floating device 3 includes a base 31, a first guide hole 32 is provided in the base 31, a floating rod 33 is provided in the first guide hole 32 and moves along the direction of the first guide hole 32, a spring 34 is also provided in the first guide hole 32 below the floating rod 33, a connecting rod 36 is provided on the floating rod 33, and the positioning block 11 is installed on the connecting rod 36.

[0021] With the above structure, the working process of the floating device 3 is as follows: when the upper template moves downward, it will press the floating device 3 to descend. When the upper template moves upward, the floating device 3 can rebound to the initial position. In this way, during the movement of the floating device 3, the positioning block 11 can move together with the floating device 3. This is to facilitate the floating device 3 to push open the stamping waste at the positioning block 11 when it rebounds.

[0022] In a preferred embodiment, a material detector 12 for detecting the presence or absence of workpiece 101 is also provided on the lower template.

[0023] With the above structure, once the workpiece 101 is placed in position, the material detector 12 can receive a signal. Based on the signal from the material detector 12, the system can determine that a workpiece has been placed at the positioning block 11, and only then will the system control the subsequent stamping process. The material detector 12 can be a proximity sensor for detecting metal.

[0024] Example 2: Further explanation in conjunction with Example 1; This embodiment is a further optimized design based on Embodiment 1. Repeated content will not be described here; only the differences from Embodiment 1 will be described. These differences are as follows: In a preferred embodiment, an annular plate 37 is provided above the first guide hole 32, and a second guide hole 371 with a smaller size than the first guide hole 32 is provided on the annular plate 37. The floating rod 33 moves within the second guide hole 371, and a guide block 38 matching the first guide hole 32 is provided below the floating rod 33. The spring 34 is below the guide block 38.

[0025] With the above structure, by setting the ring plate 37, the movement of the spring 34 within the first guide hole 32 can be restricted, so that the spring 34 cannot come out of the first guide hole 32, thereby maintaining the structural stability of the floating device 3.

[0026] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
