Description

Technical Field

[0001] This utility model relates to the field of testing machine technology, and in particular to a large-tonnage horizontal tensile testing machine. Background Technology

[0002] A tensile testing machine is a mechanically applied testing machine used to perform static load, tensile, compression, bending, shearing, peeling and other mechanical property tests on materials. It is suitable for testing various physical and mechanical properties of materials such as plastic sheets, pipes, profiles, plastic films, rubber, wires and cables, and has been widely used in the field of tensile testing.

[0003] Existing vertical tensile testing machines are limited by experimental space and cannot perform tensile tests on large-sized test pieces. Furthermore, increasing the tensile distance inevitably increases the height of the testing machine, making it less stable and prone to shaking under external forces, which also increases the difficulty of operation for operators. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the technical problem to be solved by this utility model is to propose a horizontal tensile testing machine that ensures the stability of the test process, reduces the difficulty of the operation process, and improves the convenience of operation.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] This utility model provides a large-tonnage horizontal tensile testing machine, including a base, a protective door slidably connected to the base, a viewing window provided on one side of the protective door, a fixed support seat and a movable support seat respectively provided on the top two sides of the base, a fixed plate provided on both the fixed support seat and the movable support seat, a clamping device provided between the fixed plate and the fixed support seat and the movable support seat, a groove provided on the top of the base, the movable support seat slidably connected to the groove, and the movable support seat is driven by a cylinder;

[0007] A reinforcing plate is provided on the side of the movable support away from the cylinder, and the reinforcing plate is slidably connected to the bottom of the groove. A connecting plate is provided on the side of the movable support near the cylinder, and the connecting plate is connected to the cylinder drive end. A lead screw assembly is provided on the top of the base, and a support is rotatably connected to the lead screw assembly. The support is fixed on both sides of the top of the base.

[0008] The preferred technical solution of this utility model is that the clamping device includes an electric push rod and a clamping seat. The electric push rod is disposed at the bottom of the fixed plate, the driving end of the electric push rod is connected to the clamping end, and the clamping seat is equipped with an adjusting clamping part by bolts.

[0009] The preferred technical solution of this utility model is that the bottom of the clamping end is provided with a biting protrusion, and the inner wall of the adjusting clamping part is evenly distributed with a number of sets of clamping protrusions.

[0010] A preferred embodiment of this invention is that guide rods are provided on both sides of the bottom of the clamping end, and a guide groove is provided on the top of the clamping seat corresponding to the guide rods.

[0011] The preferred technical solution of this utility model is that a sliding groove is provided on both sides of the inner wall of the groove, and a sliding seat is provided on both sides of the movable support seat to be slidably connected to the sliding groove.

[0012] The preferred technical solution of this utility model is that the lead screw assembly includes several sets of fixed seats arranged on both sides of the top of the base. Each pair of fixed seats is connected to a screw and a slide rod. The screw and slide rod are connected to the support. The screw is a double-ended screw with opposite directions of rotation. One end of the screw is connected to a motor. Two sets of sliders are provided on both the screw and the slide rod. The sliders are fixedly connected to the protective doors on both sides.

[0013] The preferred technical solution of this utility model is that an embedded groove is provided on the side of the inner wall of the groove away from the movable support seat, and the embedded groove is adapted to the reinforcing plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This utility model replaces the vertical tensile testing machine and can be adapted to large-size test pieces for tensile testing. Under the action of the reinforcing plate and the connecting plate, the movable support can move smoothly during the tensile test, which effectively improves the stability of the tensile test process. The reinforcing plate adopts a stepped structure, which further increases the contact area with the groove, improves rigidity, reduces the difficulty of operation for operators, and is equipped with a protective door to ensure the safety of on-site operators.

[0016] This utility model can select the corresponding adjusting clamping part according to the size and specifications of the test piece, and install it on the clamping seat by bolts. The bottom of the clamping end is provided with a biting protrusion, which cooperates with the clamping protrusion of the adjusting clamping part to form a multi-point biting, further increasing the firmness of the clamping of the test piece and ensuring the smooth progress of the tensile test.

[0026] During testing, the two ends of the product under test are fixed by the clamping device 5 on the fixed support 7 and the movable support 3. The protective door 2 is closed by controlling the screw assembly 6 to prevent the sample from breaking and flying in all directions during the test, which could cause injury to the staff and provide safety for the test site. The movable support 3 is driven by the cylinder to move away from the fixed support 7. The operator can observe the test process through the viewing window 21. It replaces the vertical tensile testing machine and can be used to conduct tensile tests on large-sized test pieces.
