Description

Technical Field

[0001] The utility model relates to the technical field of impact testing machines, in particular to a waste collection device for an impact testing machine. Background Art

[0002] An impact testing machine is a material testing machine that applies an impact force to a specimen to perform an impact test. Impact testing machines are categorized into manual pendulum impact testing machines, semi-automatic impact testing machines, digital impact testing machines, computer-controlled impact testing machines, drop-weight impact testing machines, and non-metallic impact testing machines.

[0003] The pendulum impact tester is a type of impact tester. It is a detector used to measure the impact resistance of metal materials under dynamic loads, thereby judging the quality condition of the material under dynamic loads.

[0004] The pendulum impact tester currently used has a protective frame net added on one or both sides of the tester to prevent the test material from rushing a long distance after breaking due to impact, thereby protecting the experimenter.

[0005] Chinese patent CN212502643U discloses a waste sample recovery device for an impact testing machine, which is applied to the technical field of impact testing machines. The waste sample recovery device for an impact testing machine includes a waste sample conveyor, a protective component, and a waste sample collection basket. The waste sample conveyor is located below the impact testing machine, the protective component is located on the side of the impact testing machine, and the waste sample collection basket is located on the side of the waste sample conveyor. The waste sample recovery device for an impact testing machine has a simple structure, is easy to manufacture, and is easy to use. It can effectively realize automatic cleaning of waste samples (waste materials), eliminate the safety hazard of easy bumps and injuries caused by narrow working space during manual cleaning, and effectively improve cleaning efficiency.

[0006] This device uses a conveyor belt installed at the bottom of a traditional protective frame. After the broken scrap hits the protective frame, it falls onto the conveyor belt and is then transported to a collection box. While this device can collect the broken scrap, the noise generated when the broken pieces hit the protective frame and the long rebound distance make centralized collection inconvenient. Utility Model Content

[0007] The purpose of the utility model is to provide a waste collection device for an impact testing machine, so as to solve the problems of waste collection of the impact testing machine in the prior art mentioned in the background technology, such as loud noise generated during the impact process, long rebound distance of metal blocks, and inconvenient collection.

[0008] To achieve the above-mentioned object, the present invention provides the following technical solution: a waste collection device for an impact testing machine, comprising a base, a pendulum impact testing machine being fixed to the upper surface of the base by screws, a protective frame for capturing waste being fixed to one end of the base by screws, a protective structure for reducing the impact rebound force of the waste being provided in the protective frame, a collection box for collecting the waste being provided at the bottom of the protective frame, the collection box being placed on one side of the base, a clearance groove being provided at the bottom of the protective frame, and a waste feeding mechanism being provided in the clearance groove;

[0009] The protection structure includes an impact plate, a friction rod is fixed to the other side of the impact plate, a guide structure for inserting the friction rod is provided in the protection frame, a connecting plate is hinged at the bottom of the impact plate, and a torsion spring is sleeved on the outside of the rotating shaft of the connecting plate.

[0010] Preferably, the protective structure further comprises a sponge, which is glued to one side of the connecting plate and the impact plate respectively.

[0011] Preferably, the waste feeding mechanism includes a feeding conveyor belt, which is installed at the bottom of the inner cavity of the protective frame. One end of the feeding conveyor belt passes through the give way slot and is located above the collection box. A feeding motor that drives the feeding conveyor belt to rotate is fixed to the outer wall of the protective frame.

[0012] Preferably, the guide structure includes a guide column, one end of which is provided with a circular hole, the inner wall of the circular hole and the outer wall of the friction rod are both glued with rubber friction sheets, and the friction rod is inserted into the circular hole.

[0013] Preferably, the guide columns and friction rods are provided in four groups, and the four friction rods are respectively fixed at the four corners of the impact plate.

[0014] Preferably, the guide structure further includes a spring, the spring is fixed in the circular hole, and one end of the spring is fixedly connected to one end of the friction rod.

[0015] Preferably, the top of the protection frame is rectangular, the bottom of the protection frame is inclined, and an open side for waste to enter is provided on the side of the protection frame close to the pendulum impact tester.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] The utility model provides an impact plate that can move backward when hit in the traditional fixed protective frame net, and glues sponge to the impact surface of the impact plate to prevent metal blocks from directly hitting the protective frame net. This structure can greatly reduce the noise intensity generated by the impact. At the same time, the buffering of the sponge and the spring can shorten the rebound distance of the metal waste. After the metal waste hits the impact plate, part of the energy is consumed by the friction of the friction rod on one side of the impact plate, so that the metal waste rebounds closer, which is convenient for unified collection of the waste. Compared with the traditional protective frame net, this device is not only more convenient for collecting waste but also produces less noise. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-4The utility model provides a technical solution: a waste collection device for an impact testing machine, comprising a base 1, a pendulum impact testing machine 2 being fixed to the upper surface of the base 1 by screws, a protective frame 3 for capturing waste being fixed to one end of the base 1 by screws, a protective structure 4 for reducing the impact rebound force of the waste being arranged in the protective frame 3, a collecting box 5 for collecting waste being arranged at the bottom of the protective frame 3, the collecting box 5 being placed on one side of the base 1, a clearance groove 6 being opened at the bottom of the protective frame 3, a waste feeding mechanism 7 being arranged in the clearance groove 6; by arranging the collecting box 5 and the clearance groove 6, when the waste feeding mechanism 7 is in operation, the broken metal waste falling on the conveyor belt can be conveyed to the collecting box 5 through the clearance groove 6 for unified collection.

[0025] The protective structure 4 includes a strike plate 401, with a friction rod 402 fixed to its other side. A guide structure 8 for inserting the friction rod 402 is provided within the protective frame 3. A connecting plate 9 is hingedly connected to the bottom of the strike plate 401, and a torsion spring 10 is sleeved on the outer portion of the rotating shaft of the connecting plate 9. By providing the strike plate 401 with the friction rod 402, when the broken metal scrap strikes the strike plate 401, the impact force of the strike plate 401 drives the friction rod 402 to move within the circular hole 802, converting some of the impact force into frictional force, thus acting as a buffer. This method can shorten the rebound distance of the metal scrap, allowing the metal scrap to easily fall onto the conveyor belt for unified collection.

[0026] The protective structure 4 further comprises a sponge 11, which is respectively glued to one side of the connecting plate 9 and the impact plate 401. By providing the sponge 11, when the broken metal scraps impact the impact plate 401, the impact noise can be reduced.

[0027] The waste feeding mechanism 7 includes a feeding conveyor belt 701, which is installed at the bottom of the inner cavity of the protection frame 3. One end of the feeding conveyor belt 701 passes through the clearance groove 6 and is located above the collection box 5. The outer wall of the protection frame 3 is fixed with a feeding motor 702 that drives the feeding conveyor belt 701 to rotate. After the feeding motor 702 is started, the feeding conveyor belt 701 rotates counterclockwise, as shown in FIG. Figure 2 As shown, the metal scraps dropped onto the feeding conveyor belt 701 are conveyed into the collecting box 5 through the chute 6 .

[0028] The guide structure 8 includes a guide post 801, one end of which is provided with a circular hole 802. A rubber friction sheet 803 is glued to the inner wall of the circular hole 802 and the outer wall of the friction rod 402. The friction rod 402 is inserted into the circular hole 802. The provision of the rubber friction sheet 803 increases friction, thereby partially absorbing the impact force when the guide post 801 slides within the circular hole 802.

[0029] The guide posts 801 and the friction rods 402 are provided in four groups, and the four friction rods 402 are respectively fixed at the four corners of the impact plate 401 .

[0030] The guide structure 8 further includes a spring 804 . The spring 804 is fixed in the circular hole 802 . One end of the spring 804 is fixedly connected to one end of the friction rod 402 .

[0031] The top of the protection frame 3 is rectangular, the bottom of the protection frame 3 is inclined, and an open side 12 for waste to enter is provided on a side of the protection frame 3 close to the pendulum impact tester 2 .

[0032] During use, the structure of the pendulum impact tester 2 is the same as that of the impact tester in the prior art. After the metal block to be tested is placed in the groove of the impact tester base, the pendulum is controlled to swing downward. When the pendulum hits the metal block, the metal block breaks. The broken waste material hits the sponge 11 and then continues to hit the impact plate 401. Under the action of the impact force, the impact plate 401 drives the friction rod 402 to move in the circular hole 802, converting part of the impact force into frictional force for consumption. This method can shorten the rebound distance of the metal waste. This makes it easier for the metal waste to fall onto the conveyor belt and facilitates unified collection. Compared with traditional waste collection devices, this device has a shorter waste rebound distance, is more convenient for collection, and has low noise from waste impact.

[0033] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
