Description

Technical Field

[0001] This utility model mainly relates to the field of steel strip testing, specifically to a tensile testing machine for steel strip. Background Technology

[0002] As is well known, a steel strip includes the strip body and connecting buckles set at both ends of the strip body. The main purpose of the tensile test is to obtain the maximum resistance to damage of the steel strip in order to determine the actual bearing capacity of the steel strip.

[0003] In the invention patent application CN201821775373.6, published on July 26, 2019, entitled "A Tensile Testing Device for Stainless Steel Strip," a long strip-shaped strip body and matching connectors at both ends of the strip body are included. The connectors are anti-detachment type. The testing device includes a test platform detachably mounted on the base of a tensile testing machine, a positioning module mounted on the test platform, a positioning tube horizontally positioned on the positioning module, and a connecting module above the positioning tube through which the strip body passes. This device directly applies tensile force to the strip body, causing the steel strip to break, thus more accurately demonstrating the strip's resistance to breakage. Furthermore, it has a simple structure and is easy to implement.

[0004] However, this tensile testing device cannot test the tensile force at different positions of the steel strip; it can only test the middle position of the steel strip with support at both ends. Utility Model Content

[0005] 1. The technical problem to be solved by the utility model:

[0006] This utility model provides a tensile testing machine for steel strips, which solves the problem that it is impossible to test the tensile force at different positions of the steel strip, and that it can only test the middle position of the steel strip with the two ends as supports.

[0007] 2. Technical Solution:

[0008] To achieve the above objectives, the technical solution provided by this utility model is as follows: a tensile testing machine for steel strip, comprising a smooth base plate, a positioning buckle fixedly connected to the upper surface of the smooth base plate, sliding rails fixedly connected to the two side surfaces of the smooth base plate, an electric trolley provided on the upper surface of the sliding rails, an upper suspension frame fixedly connected to the upper surface of the electric trolley, and a lower support box provided below the upper suspension frame on the surface of the smooth base plate.

[0009] Furthermore, the upper suspension frame forms a movable structure above the lower support box via an electric trolley, and the lower support box is fixed above the smooth bottom plate by positioning buckles.

[0010] Furthermore, the upper suspension frame includes a side support arm, a reinforcing rod fixedly connected to the surface of the side support arm, a slotted slider provided on the top surface of the side support arm, a transverse support plate slidably connected to the upper surface of the slotted slider, a traction cylinder provided on the upper surface of the transverse support plate, a screw hook installed at the lower end of the traction cylinder, and a "T"-shaped tie rod installed at the lower end of the screw hook. The "T"-shaped tie rod is configured as a "T"-shaped structure consisting of a hollow hook and a transversely fixed base rod.

[0011] Furthermore, the traction cylinder is mounted on the upper surface of the empty slot slider via a transverse support plate, and the "T"-shaped tie rod and screw hook form a lifting structure through the traction cylinder.

[0012] Furthermore, the lower support box includes a sliding box, the lower surface of which is provided with a recessed groove, the upper surface of which is provided with a recessed groove, the surface of which is provided with a plurality of tie rod grooves, and the surface of which a lower support tie rod is fitted and connected.

[0013] Furthermore, the sliding box body forms a sliding structure on the upper surface of the smooth bottom plate, and forms a fixed structure by the fitting connection between the recessed groove and the positioning buckle. The pull rod groove on the surface of the sinking groove extends to both sides of the sinking groove, and a slot is provided in the sliding box body. The lower support pull rod is installed on the surface of the pull rod groove through the slot.

[0014] 3. Beneficial effects:

[0015] This utility model features a reasonable design. During steel strip tensile testing, the upper end of the steel strip is installed at the center of the hollow hook above the "T"-shaped tie rod. When testing multiple steel strips, the strips are installed on both sides of a horizontally fixed base rod, with the lower end inserted into the tie rod groove. Simultaneously, the lower support tie rod is inserted between the tie rod groove and the steel strip through slots on both sides of the sliding housing, providing initial fixation. The lower support tie rod provides two-point support for the lower end of the steel strip, creating a triangular support structure. An electric trolley moves the upper suspension frame and the top support point of the steel strip, allowing for different postures of the steel strip during tensile testing and enriching the diversity of test data.

[0016] During the tensile test, the traction cylinder in the upper suspension frame is activated, which drives the screw hook, the "T"-shaped tie rod, and the upper end of the steel belt to pull upward, thus achieving the purpose of tensile testing. In addition, during the test, the electric trolley is activated to make the upper suspension frame slide on the sliding track surface, thereby changing the test posture of the steel belt during the test.

[0027] See attached document Figure 1-4 The system includes a smooth base plate 1, a positioning buckle 2 fixedly connected to the upper surface of the smooth base plate 1, sliding rails 3 fixedly connected to the two side surfaces of the smooth base plate 1, an electric trolley 4 mounted on the upper surface of the sliding rails 3, an upper suspension frame 5 fixedly connected to the upper surface of the electric trolley 4, and a lower support box 6 mounted below the upper suspension frame 5 on the surface of the smooth base plate 1. The upper suspension frame 5 forms a movable structure above the lower support box 6 via the electric trolley 4, and the lower support box 6 is fixed above the smooth base plate 1 by the positioning buckle 2. This technical solution realizes the posture change of the steel strip during the inspection process through the movable upper suspension frame 5.

[0028] The upper suspension frame 5 includes a side support arm 501, a reinforcing rod 502 fixedly connected to the surface of the side support arm 501, a slotted slider 503 provided on the top surface of the side support arm 501, a transverse support plate 504 slidably connected to the upper surface of the slotted slider 503, a traction cylinder 505 provided on the upper surface of the transverse support plate 504, a screw hook 506 installed at the lower end of the traction cylinder 505, a "T"-shaped pull rod 507 installed at the lower end of the screw hook 506, the traction cylinder 505 is installed on the upper surface of the slotted slider 503 through the transverse support plate 504, the "T"-shaped pull rod 507 and the screw hook 506 form a lifting structure through the traction cylinder 505, the "T"-shaped pull rod 507 is set as a "T"-shaped structure composed of a hollow hook and a transversely fixed base rod.

[0029] In this embodiment, during the steel strip tensile test, the upper end of the steel strip is installed at the center of the hollow hook above the "T"-shaped tie rod 507. When testing multiple steel strips, the steel strips are installed on both sides of the horizontally fixed base rod, and the lower end of the steel strip is inserted into the tie rod groove 604. At the same time, the lower support tie rod 605 is inserted between the tie rod groove 604 and the steel strip through the slots on both sides of the sliding box 601 to initially fix the steel strip. The lower support tie rod 605 provides two-point support for the lower end of the steel strip, making the steel strip form a triangular support. The upper suspension frame 5 and the top support point of the steel strip are moved by the electric trolley 4, which realizes the different postures of the steel strip during tensile testing, enriching the diversity of test data.

[0030] The lower support housing 6 includes a sliding housing 601. The lower surface of the sliding housing 601 has a recessed groove 602, and the upper surface of the sliding housing 601 has a recessed groove 603. The surface of the recessed groove 603 has several pull rod grooves 604. Lower support pull rods 605 are fitted into the surfaces of the pull rod grooves 604. The sliding housing 601 forms a sliding structure on the upper surface of the smooth base plate 1 and a fixed structure through the fitting connection between the recessed groove 602 and the positioning buckle 2. The pull rod grooves 604 on the surface of the recessed groove 603 extend to both sides of the recessed groove 603, and slots are provided in the sliding housing 601. The lower support pull rods 605 are installed on the surface of the pull rod grooves 604 through these slots.

[0031] In this embodiment, when performing tensile testing, the traction cylinder 505 in the upper suspension frame 5 is activated, which drives the screw hook 506, the "T"-shaped tie rod 507 and the upper end of the steel belt to pull upward, thereby performing tensile testing on the steel belt and achieving the purpose of tensile testing. During the testing process, the electric trolley 4 is activated to make the upper suspension frame 5 slide on the surface of the sliding track 3, thereby achieving the purpose of changing the testing posture of the steel belt during the testing process.
