An impact testing machine with automatic sample delivery

Abstract

The utility model relates to the technical field of impact testing machines, and discloses an impact testing machine with automatic sample delivery, including two supporting bases symmetrically fixedly installed on both sides of the bottom of the front side of the impact testing machine. The impact testing machine with automatic sample delivery drives the reciprocating screw to rotate through the output end of the motor. As the reciprocating screw rotates, the push block moves from the end of the conveying table away from the impact testing machine to the end close to the impact testing machine. When it reaches the end of the reciprocating screw close to the impact testing machine, the push block starts to move toward the end away from the impact testing machine, so that the metal material to be tested is delivered into the test end of the impact testing machine, and tested by the hammer of the impact testing machine. The tested metal material is ejected from the test end of the impact testing machine by the subsequent metal material input, without the need to manually place the metal material or take out the tested metal material, thereby improving the efficiency of the impact test.

Description

Technical Field

[0001] The utility model relates to the technical field of impact testing machines, in particular to an impact testing machine with automatic sample delivery. Background Art

[0002] Impact testing machine (English name: impact testing machine) refers to a material testing machine that applies impact test force to the sample to perform impact tests. Impact testing machines are divided into manual pendulum impact testing machines, semi-automatic impact testing machines, digital display impact testing machines, microcomputer-controlled impact testing machines, drop-weight impact testing machines, and non-metallic impact testing machines. By replacing the pendulum and the sample base, two forms of tests, simply supported beam and cantilever beam, can be achieved. Drop-weight impact testing machine is another type of impact testing machine, suitable for drop-weight impact testing of ferritic steel (especially various pipeline steels).

[0003] At present, the existing pendulum impact testing machine delivers samples manually and in a single time, but this method of sample delivery is inefficient and reduces the efficiency of the impact test. Utility Model Content

[0004] 1. Technical issues to be solved

[0005] In view of the deficiencies of the prior art, the utility model provides an impact testing machine with automatic sample delivery, which is equipped with a motor (406) output end driving a reciprocating screw (405) to rotate. As the reciprocating screw (405) rotates, a moving block (408) reciprocates on the reciprocating screw (405). As the moving block (408) reciprocates, a push block (407) reciprocates on a conveying table (403). The push block (407) moves from one end of the conveying table (403) away from the impact testing machine (1) to the end of the conveying table (403) close to the impact testing machine (1). When the push block (407) reaches the end of the conveying table (403) far from the impact testing machine (1), the push block (407) moves to the end of the conveying table (403) close to the impact testing machine (1). When the reciprocating screw rod (405) reaches one end close to the impact tester (1), the push block (407) starts to move toward the end away from the impact tester (1), thereby delivering the metal material to be tested into the test end of the impact tester (1) and testing it through the hammer of the impact tester (1). The tested metal material is ejected from the test end of the impact tester (1) by the subsequent metal material input along with the subsequent metal material, without the need to manually place the metal material or take out the tested metal material, thereby improving the efficiency of the impact test and solving the above-mentioned technical problems.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an impact testing machine with automatic sample feeding, comprising an impact testing machine, two limit guide plates are symmetrically fixedly installed on both sides of the testing end of the impact testing machine, two support bases are symmetrically fixedly installed on both sides of the front bottom of the impact testing machine, the top surfaces of the two support bases are respectively fixedly connected to the two ends of the bottom surface of the sample feeding structure, and the sample feeding structure is used to feed the metal material to be tested into the impact testing machine for testing;

[0008] The sample conveying structure is composed of a fixed block, a limiting rod, a conveying table, a connecting block, a reciprocating screw rod, a motor, a pushing block and a moving block.

[0009] The two ends of the limit rod are respectively fixedly connected to the middle ends of the two fixed blocks, and the two limit rods are parallel to each other. The two limit rods are respectively located on both sides of the bottom surface of the conveying table. A through groove is opened in the middle end of the conveying table. The two ends of the moving block are respectively slidably connected to the limit rods, and a reciprocating slider is fixedly installed at the middle end of the bottom end of the moving block.

[0010] As a preferred technical solution of the utility model, a motor is fixedly installed at the bottom middle end of the side of the conveying table away from the impact testing machine, the output end of the motor is fixedly connected to one end of the reciprocating screw, and the output end of the motor is located at the middle end of the bottom surface of the conveying table, and a connecting block is fixedly installed at the middle end of the bottom surface of the conveying table away from the motor, and the other end of the reciprocating screw is rotatably connected to the middle end of the connecting block.

[0011] As a preferred technical solution of the utility model, the reciprocating thread on the outer wall of the reciprocating screw is connected to the reciprocating key thread at the middle end of the moving block, a push block is fixedly installed on the top surface of the moving block, and a buffer pad is fixedly installed on the front surface of the push block.

[0012] As the preferred technical solution of the utility model, the bottom surface of the fixed block is fixedly connected to the top surface of the supporting base, the output end of the conveying table is connected to the test end of the impact testing machine, and the side of the conveying table adjacent to the impact testing machine is tightly fitted with the limiting guide plate.

[0013] Compared with the prior art, the utility model provides an impact testing machine with automatic sample delivery, which has the following beneficial effects:

[0014] The utility model drives the reciprocating screw to rotate through the output end of the motor. As the reciprocating screw rotates, the moving block reciprocates on the reciprocating screw. As the moving block reciprocates, the pushing block also reciprocates on the conveying table. The pushing block moves from the end of the conveying table away from the impact testing machine to the end close to the impact testing machine. When it reaches the end of the reciprocating screw close to the impact testing machine, the pushing block starts to move toward the end away from the impact testing machine, thereby delivering the metal material to be tested into the test end of the impact testing machine and testing it with the hammer of the impact testing machine. The tested metal material is ejected from the test end of the impact testing machine by the subsequent metal material as the subsequent metal material is input. There is no need to manually place the metal material or take out the tested metal material, thereby improving the efficiency of the impact test. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] See also Figure 1-5 , an impact testing machine with automatic sample feeding, comprising two support bases 3 symmetrically installed at the bottom of the front side thereof, the top surfaces of the two support bases 3 are respectively fixedly connected to the two ends of the bottom surface of the sample feeding structure 4, in addition, the test end of the impact testing machine 1 is fixedly installed with two limit guide plates 2, and the two limit guide plates 2 are symmetrical to each other, and the function of the sample feeding structure 4 is to feed the metal material to be tested into the test end of the impact testing machine 1 for testing;

[0025] The sample delivery structure 4 is specifically composed of a fixed block 401, a limit rod 402, a delivery table 403, a connecting block 404, a reciprocating screw rod 405, a motor 406, a push block 407 and a moving block 408;

[0026] Four fixing blocks 401 are fixedly installed at the four corners of the bottom surface of the conveying table 403, and the bottom surface of the fixing block 401 is fixedly connected to the top surface of the supporting base 3. The two ends of the limiting rod 402 are fixedly connected to the middle ends of the two fixing blocks 401, and the two limiting rods 402 are parallel to each other. At the same time, the two limiting rods 402 are respectively located on both sides of the bottom surface of the conveying table 403, and the output end of the conveying table 403 is connected to the test end of the impact testing machine 1. The limiting guide plate 2 of the impact testing machine 1 is tightly fitted with a side of the conveying table 403 close to the impact testing machine 1, thereby limiting the metal material to be conveyed to avoid the metal material The conveying table 403 is detached from the test end of the impact tester 1, and a through groove is opened in the middle end of the conveying table 403, and the two ends of the moving block 408 are respectively slidably connected with the limit rod 402, and a reciprocating slider 409 is fixedly installed at the middle end of the bottom end of the moving block 408. A motor 406 is fixedly installed at the middle end of the side of the conveying table 403 away from the impact tester 1, and the output end of the motor 406 is fixedly connected to one end of the reciprocating screw rod 405. A connecting block 404 is fixedly installed at the middle end of the side of the conveying table 403 away from the motor 406, and the other end of the reciprocating screw rod 405 is rotatably connected to it. The outer wall of the reciprocating screw rod 405 The reciprocating thread on the moving block 408 is connected with the reciprocating key thread at the middle end of the moving block 408. A push block 407 is fixedly installed on the top surface of the moving block 408. A buffer pad is fixedly installed on the front of the push block 407. The reciprocating screw rod 405 is driven to rotate by the output end of the motor 406. As the reciprocating screw rod 405 rotates, the moving block 408 reciprocates on the reciprocating screw rod 405. As the moving block 408 reciprocates, the push block 407 also reciprocates on the conveying table 403. The push block 407 moves from the end of the conveying table 403 away from the impact tester 1 to the end close to the impact tester 1. When it reaches the reciprocating thread, the push block 407 moves back and forth on the conveying table 403. When the rod 405 is close to one end of the impact testing machine 1, the push block 407 starts to move toward the end away from the impact testing machine 1, thereby delivering the metal material to be tested into the test end of the impact testing machine 1 and testing it through the hammer of the impact testing machine 1. The tested metal material is pushed out from the test end of the impact testing machine 1 by the subsequent metal material input along with the subsequent metal material. There is no need to manually place the metal material or take out the tested metal material, thereby improving the efficiency of the impact test. In addition, a material collection frame can be placed at the rear end of the test end of the impact testing machine 1 to collect the tested metal material.

[0027] When in use, after moving the push block 407 to the end away from the impact testing machine 1, the metal material to be tested is placed on the middle end of the conveying table 403, and after it is attached to the surface of the buffer pad, multiple metal materials are placed in sequence. At the same time, a collection frame is placed on the side of the test end of the impact testing machine 1 away from the conveying table 403. During testing, the motor 406 is started to drive the reciprocating screw 405 to rotate, and the push block 407 rotates with the reciprocating screw 405 and moves toward the impact testing machine 1, thereby sending the metal material to be tested into the test end of the impact testing machine 1. When the metal to be tested enters the test end of the impact testing machine 1, the tester controls the motor 406 to turn off through the PLC controller, and the impact testing machine 1 is started to test the metal material to be tested. After the metal material detection is completed, the motor 406 is continued to be controlled to start, and another metal material to be tested is sent into the impact testing machine 1. At this time, the metal material to be tested will push the metal material that has completed the detection out of the test end of the impact testing machine 1 and fall into the collection frame for recovery.
