Description

Technical Field

[0001] This utility model relates to the field of stamping sheet metal testing technology, and in particular to a raw material screening machine for the production of metal stamping parts. Background Technology

[0002] Metal stamping parts refer to metal parts processed by stamping technology. This process uses molds and stamping equipment (such as punch presses) to apply pressure to metal sheets, causing them to separate or plastically deform, thereby obtaining parts with the required shape and size.

[0003] Chinese patent CN222568504U discloses a raw material screening machine for the production of metal stamping parts. This machine uses an image recognition module to detect protrusions, depressions, or cracks on the surface of metal sheets. However, during inspection, the image recognition module identifies surface features of the metal sheet without actual contact. Pure image recognition cannot directly measure thickness, and therefore cannot directly detect the flatness and thickness tolerance of the metal sheet. Furthermore, the presence of reflections and shadows on the metal sheet surface directly affects the inspection results, leading to inaccurate visual inspection. Additionally, for sheets with defects, the machine rotates to select the output direction and transports the sheet separately, resulting in a complex transport process that increases inspection time and reduces efficiency. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to propose a raw material screening machine for the production of metal stamping parts, which moves the sheet metal for comprehensive inspection, records the overall flatness of the sheet metal and the thickness tolerance at different positions, improves the accuracy of sheet metal structure and shape inspection, and increases the efficiency of inspection and separation output.

[0006] To achieve the above objectives, this utility model proposes a support frame, a conveying mechanism, a detection component, and a material transfer component. The conveying mechanism is disposed within the support frame, the material transfer component is disposed on the support frame, and the detection component includes a connecting frame, multiple dial indicators, and multiple adjustment mechanisms. The connecting frame is disposed on the support frame, the multiple adjustment mechanisms are disposed on the connecting frame, and the multiple dial indicators are disposed on the connecting frame and extend into the adjustment mechanisms.

[0007] This utility model discloses a raw material screening machine for the production of metal stamping parts. It measures the flatness and thickness tolerance of stamped metal sheets. The metal sheets are conveyed within a support frame via a conveying mechanism, passing through a detection component for inspection. During conveying, multiple horizontally placed adjustment mechanisms within the connecting frame roll in contact with the sheet surface, moving up and down to adjust with the surface undulations. These mechanisms also contact the detection ends of multiple corresponding dial indicators. Data comparison is achieved by adjusting the dial indicator pointers, thus realizing the detection of thickness tolerance and flatness of the metal sheets. After conveying and inspection, at the outlet of the support frame, the telescopic adjustment of the conveying component separates and screens out unqualified sheets, improving inspection efficiency.

[0008] In addition, the raw material screening machine for the production of metal stamping parts according to the present invention may also have the following additional technical features:

[0009] Specifically, the adjustment mechanism includes two symmetrical limiting frames, two sliding rods, two connecting blocks, and a detection wheel. The two symmetrical limiting frames are disposed within the connecting frame, the two sliding rods are respectively disposed within the limiting frames, the two connecting blocks are respectively disposed on the two sliding rods, and the detection wheel is rotatably connected between the two connecting blocks and makes rolling contact with the detection end of the dial indicator.

[0010] Specifically, multiple dial indicators are arranged at equal intervals along the horizontal direction of the connecting frame, and multiple adjustment mechanisms correspond to the positions of the dial indicators.

[0011] Specifically, the conveying mechanism includes a conveyor belt, a plurality of support rollers, and a first driving device, wherein the conveyor belt is disposed within the support frame via the plurality of support rollers, and the first driving device is disposed outside the support frame and connected to one of the support rollers.

[0012] Specifically, the material transfer assembly includes two second drive devices, two mounting brackets, and multiple material transfer cylinders. The two second drive devices are located on the outside of the support frame, the two mounting brackets are located at the execution ends of the second drive devices, and the multiple material transfer cylinders are located between the two mounting brackets.

[0021] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0022] The raw material screening machine for producing metal stamping parts according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0023] like Figures 1-5 As shown, the raw material screening machine for producing metal stamping parts according to this utility model embodiment may include a support frame 1, a conveying mechanism 2, a detection component 3, and a material transfer component 4.

[0024] The conveying mechanism 2 is located inside the support frame 1, and the material conveying component 4 is located on the support frame 1.

[0025] It should be noted that the conveying mechanism 2 rotates and conveys the metal sheet within the support frame 1, and is stably supported by the support frame 1 and the bottom support legs. The material transfer component 4 processes the tested metal sheet on the discharge port side of the support frame 1, thereby realizing the conveying of qualified sheets and the screening out of unqualified sheets.

[0026] The detection component 3 includes a connecting frame 31, multiple dial gauges 32, and multiple adjustment mechanisms 33.

[0027] The connecting frame 31 is mounted on the support frame 1, multiple adjusting mechanisms 33 are mounted on the connecting frame 31, and multiple dial gauges 32 are mounted on the connecting frame 31 and extend into the adjusting mechanisms 33.

[0028] It should be noted that multiple dial gauges 32 and multiple adjustment mechanisms 33 are positioned correspondingly and are evenly spaced along the horizontal direction of the connecting frame 31. The detection end of the dial gauge 32 extends through the connecting frame 31 into the adjustment mechanism 33. The adjustment mechanism 33 contacts the surface of the metal plate, and the up-and-down movement of the adjustment mechanism 33 contacts the detection end of the dial gauge 32 to achieve the detection of the flatness and thickness tolerance of the metal plate surface.

[0029] Specifically, during the actual testing process, relevant personnel place the metal sheet on the conveying mechanism 2. The metal sheet moves towards the discharge port of the support frame 1 and comes into contact with multiple horizontally distributed testing components 3. The flatness and thickness tolerance of the metal sheet are tested by calculating the pointer fluctuation and numerical difference of the dial indicator 32. If the pointer of the dial indicator 32 moves within the allowable tolerance range, the stamping requirements are met, and the sheet is horizontally conveyed by the material transfer component 4. If the detected difference exceeds the allowable tolerance range, the stamping requirements of the metal sheet are not met, and the material transfer component 4 moves away from the support frame 1. The unqualified sheet slides down the slope between the material transfer component 4 and the discharge port of the support frame 1, achieving separate output of the unqualified sheet and improving the efficiency of sheet testing and separation.

[0030] In one embodiment of this utility model, such as Figure 5 As shown, the adjustment mechanism 33 includes two symmetrical limit frames 331, two slide rods 332, two connecting blocks 333 and a detection wheel 334.

[0031] Two symmetrical limiting frames 331 are set inside the connecting frame 31, two sliding rods 332 are respectively set inside the limiting frames 331, two connecting blocks 333 are respectively set on the two sliding rods 332, and the detection wheel 334 is rotatably connected between the two connecting blocks 333 and rolls in contact with the detection end of the dial indicator 32.

[0032] It should be noted that the detection wheel 334 described in this embodiment is adjusted by sliding up and down along two corresponding slide rods 332 via two connecting blocks 333. A support spring is wound around the outside of the slide rods 332. The downward pressure of the support spring makes the connecting block 333 located at the bottom of the limiting frame 331. The two symmetrical limiting frames 331 fix the two slide rods 332 to the bottom of the connecting frame 31, thereby limiting the position of the detection wheel 334 and satisfying the up and down movement of the detection wheel 334. The up and down movement stroke of the detection wheel 334 is detected by the detection end of the dial indicator 32.

[0033] In one embodiment of this utility model, such as Figure 1 and Figure 2 As shown, multiple dial gauges 32 are arranged at equal intervals along the horizontal direction of the connecting frame 31, and multiple adjustment mechanisms 33 correspond to the positions of the dial gauges 32.

[0034] It should be noted that by using multiple horizontally arranged dial gauges 32 and corresponding multiple adjustment mechanisms 33, the inspection surface of the metal sheet is expanded, thereby increasing the inspection efficiency of flatness and thickness tolerance.

[0035] In one embodiment of this utility model, such as Figure 1 and Figure 3 As shown, the conveying mechanism 2 includes a conveyor belt 21, multiple support rollers 22 and a first drive device 23.

[0036] The conveyor belt 21 is installed inside the support frame 1 by multiple support rollers 22, and the first drive device 23 is installed on the outside of the support frame 1 and connected to one of the support rollers 22.

[0037] It should be noted that the first driving device 23 described in this embodiment uses a rotary motor to drive one of the support rollers 22 to rotate, while simultaneously driving the conveyor belt 21 to transport the metal sheet. Multiple support rollers 22 provide stable support for the conveyor belt 21, increasing the stability of the conveying process.

[0038] In one embodiment of this utility model, such as Figure 1 and Figure 3 As shown, the material transfer assembly 4 includes two second drive units 41, two mounting brackets 42, and multiple material transfer cylinders 43.

[0039] Two second drive units 41 are located on the outside of the support frame 1, two mounting frames 42 are located at the execution end of the second drive units 41, and multiple feed cylinders 43 are located between the two mounting frames 42.

[0040] It should be noted that the second driving device 41 described in this embodiment is driven by a cylinder. Through the extension and retraction ends of the two cylinders, the two mounting brackets 42 are moved back and forth to adjust, and the positions of multiple material transfer cylinders 43 are adjusted simultaneously to change the distance between them and the support frame 1, so as to facilitate the separation and feeding of unqualified metal plates.

[0041] In summary, the raw material screening machine for metal stamping parts production according to this utility model embodiment moves the sheet metal for comprehensive inspection, records the overall flatness of the sheet metal and the thickness tolerance at different locations, improves the accuracy of sheet metal structure and shape inspection, and increases inspection and separation output efficiency.
