Abstract
Description
Technical Field
[0001] This utility model belongs to the field of sheet metal processing and testing technology, specifically a tensile strength testing device for sheet metal. Background Technology
[0002] Tensile strength testing is a necessary inspection procedure after the manufacturing and processing of color-coated steel sheets. When conducting tensile tests on metal sheets and color-coated steel sheets, operators often use clamps to clamp and fix the metal sheets. However, the clamping range of existing clamps is limited. If the thickness of the metal sheet is greater than the clamping range, the existing clamps will not be able to clamp and fix the metal sheet, and it is necessary to replace them with clamps with a larger clamping range. This is inconvenient to operate and has limited practicality. Summary of the Invention
[0003] The purpose of this utility model is to address the aforementioned problems in existing technologies and propose a solution. A tensile strength testing device for sheet materials has the advantage of greater compatibility.
[0004] The purpose of this utility model can be achieved through the following technical solution: a tensile strength testing device for sheet metal, including a processing table, a placement frame installed on one side of the processing table, a first support part for supporting the lower surface of one end of the sheet metal inside the placement frame, a first hydraulic cylinder installed on the top of the placement frame, a first lifting pressure plate for pressing one end of the sheet metal on the piston rod of the first hydraulic cylinder, and a feed port opened on both sides of the placement frame. A drive groove is provided on the processing table, and a guide rail is installed in the drive groove. A sliding seat is slidably connected to the guide rail. A second drive motor is installed on the other side of the processing table. A lead screw is driven and connected to the drive shaft of the second drive motor. The lead screw passes through the sliding seat and is connected to the sliding seat. A second frame is installed on the sliding seat. The second frame has a second support part for supporting the lower surface of the other end of the plate. A second hydraulic cylinder is installed on the second frame. The piston rod of the second hydraulic cylinder is fixedly connected to a second lifting pressure plate for pressing down the other end of the plate.
[0005] Preferably, the processing table is also equipped with a limiting guide for guiding and limiting the second frame.
[0006] Preferably, the first support portion and the second support portion are set at the same height.
[0007] Preferably, the first support portion has an inclined portion on the side near the second frame to facilitate feeding.
[0008] Preferably, an observation window is also installed on one side of the placement frame.
[0009] Compared with the prior art, the advantages of this utility model are: by setting a movable and stretchable second frame on the other side of the processing table, the second frame is driven to move left or right by the second drive motor, and the second lifting plate is pressed on the upper surface of the plate by the second hydraulic cylinder, which is conducive to automatic stretching of the plate. At the same time, for plates of different thicknesses, the first lifting plate can still be pressed down to the upper surface of one end of the plate first, and the second frame automatically moves to the corresponding position so that the second lifting plate is pressed down to the upper surface of the other end of the plate. Then, the tensile test is carried out by moving the second frame to the right. This is convenient to operate and has stronger compatibility. Attached Figure Description

Detailed Implementation
[0014] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0015] like Figures 1 to 3 As shown, a tensile strength testing device for sheet metal includes a processing table 2, a placement frame 3 installed on one side of the processing table 2, a first support part 31 for supporting the lower surface of one end of the sheet metal inside the placement frame 3, a first hydraulic cylinder 32 installed on the top of the placement frame 3, a first lifting pressure plate 33 for pressing one end of the sheet metal is fixed on the piston rod of the first hydraulic cylinder 32, and a feed port 34 is opened on both sides of the placement frame 3. A drive groove 41 is provided on the processing table 2, and a guide rail 42 is installed in the drive groove 41. A sliding seat 43 is slidably connected to the guide rail 42. A second drive motor 44 is installed on the other side of the processing table 2. A lead screw 45 is driven and connected to the drive shaft of the second drive motor 44. The lead screw 45 passes through the sliding seat 43 and is connected to the sliding seat 43. A second frame 46 is installed on the sliding seat 43. The second frame 46 has a second support part 47 for supporting the lower surface of the other end of the plate. A second hydraulic cylinder 48 is installed on the second frame 46. The piston rod of the second hydraulic cylinder 48 is fixedly connected to a second lifting pressure plate 49 for pressing the other end of the plate.
[0016] With the above structure, a movable and stretchable second frame 46 is provided on the other side of the processing table 2. The second drive motor 44 drives the second frame 46 to move left or right, while the second hydraulic cylinder 48 presses the second lifting plate 49 onto the upper surface of the plate. This facilitates automatic stretching of the plate. For plates of different thicknesses, the first lifting plate 33 can still be pressed down onto the upper surface of one end of the plate, and the second frame 46 can automatically move to the corresponding position, so that the second lifting plate 49 is pressed down onto the upper surface of the other end of the plate. Then, the second frame 46 is moved to the right to perform a tensile test. This makes the operation convenient and the compatibility stronger.
[0017] Specifically, such as Figures 1 to 3 As shown, the processing table 2 is also equipped with a limiting guide part 5 for guiding and limiting the second frame 46.
[0018] With the above structure, by setting the limiting guide part 5, the second frame 46 can be limited in the front and back directions when it moves to the left or right, so as to prevent the second frame 46 from deviating during movement and thus affecting the subsequent test results. The structure is simple and reliable.
[0019] like Figures 1 to 3 As shown, the first support portion 31 and the second support portion 47 are set at the same height. This type of structure can keep the height of both ends of the plate consistent, reducing errors during testing.
[0020] like Figures 1 to 3 As shown, the first support 31 has an inclined portion 6 on the side near the second frame 46 for facilitating material feeding. By providing the inclined portion 6, it is convenient to place the plate into the placement frame 3 and to easily send one end of the plate directly under the first lifting pressure plate 33 for fixing one end of the plate.
[0021] like Figures 1 to 3 As shown, an observation window 7 is also installed on one side of the placement frame 3. This structure allows operators to easily observe the tensile strength of the sheet material in real time.
[0022] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.
[0023] Furthermore, the use of terms such as "first" and "second" in this invention is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Meanwhile, the word "and / or" throughout the text means including three solutions; for example, "A and / or B" includes solution A, solution B, or a solution that simultaneously satisfies A and B. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.
[0024] All of the above components are general standard parts or components known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.
[0025] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
