[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] Specific implementation cases:

[0018] like Figure 1As shown, a waste discharge device for a stamping machine tool comprises a chassis 1, an adjustment frame 2 is installed below the chassis 1 for adjusting the application height of the entire device, and can be applied to different types of stamping machines, a cover 3 is installed on the chassis 1, a waste inlet 31 is installed on the cover 3, a pushing mechanism 4 is installed on both sides of the chassis 1, a recovery box 5 is installed below the chassis 1, and a waste collection device (not shown in the figure) is installed below the recovery box 5;

[0019] When in use, the device is placed at the waste outlet of the punching machine, and the device is adjusted to a suitable position by using the adjusting frame 2. The punching waste enters the chassis 1 from the waste inlet 31, and is pushed into the recovery box 5 by the pushing mechanism 4. The function of the cover 3 is to prevent the fine waste dust in the chassis 1 from scattering and affecting the indoor air quality and causing harm to the health of the operator.

[0020] like Figure 2 As shown, the chassis 1 is provided with a slide 6, the upper end of the slide 6 is divided into a slope, and the waste enters the pushing mechanism 4 along the slope;

[0021] The push mechanism 4 includes a rotating wheel 41, which is mounted on the outside of the chassis 1, and a first crank 42 is mounted on the rotating wheel 41. The driving mode of the rotating wheel 41 is motor-driven. A second crank 43 is mounted on the other end of the first crank 42, and a pulley 49 is mounted on the second crank 43. A third crank 44 is mounted on the other side of the pulley 49, and three groups of pulleys 49 are mounted on the third crank 44. A limit plate 45 is mounted on the outer side of the pulley 49 to limit the moving direction of the second crank 43 and the third crank 44;

[0022] The rotating wheel 41 drives the first crank 42 to rotate, the first crank 42 drives one end of the second crank 43 to make an arc motion, the other end of the second crank 43 is limited by the limiting plate 45 to make a linear motion, the second crank 43 drives the third crank 44 to make a linear motion, and the motion range of the third crank 44 is limited by the limiting plate 45;

[0023] A connecting frame 46 is installed on the second crank 43, and a connecting frame 46 is installed on the third crank 44. The connecting frame 46 is slidably connected to the side of the chassis 1, and a limiting block 47 is provided on the connecting frame 46. The limiting block 47 is fixed and has an obtuse arc groove with a certain angle on its surface. A push plate 48 is installed on the limiting block 47. The limiting block 47 is rotatably connected to the push plate 48, and a torsion spring (not shown in the figure) is provided at the connection for returning the push plate 48.

[0024] The push plate 48 is made of soft plastic, and the bottom of the push plate 48 contacts the surface of the slideway 6. Two groups of push plates 48 are provided, which are respectively installed on two connecting frames 46. A positioning protrusion (not shown in the figure) is provided at the connection between the upper part of the push plate 48 and the limit block 47;

[0025] One of the push plates 48 is mounted on the second crank 43, and the other push plate 48 is mounted on the third crank 44;

[0026] For ease of understanding, the mechanism has an initial state. In the initial state, the first crank 42 is horizontal to the ground and close to the waste inlet 31, and the second crank 43 is connected to one end of the first crank 42 close to the waste inlet 31, so that the second crank 43 as a whole overlaps with the first crank 42. In this initial state, the second crank 43 and the third crank 44 are farthest from the recycling box 5, and the torsion spring provided at the connection between the limit block 47 and the push plate 48 is in an open state, and the positioning protrusion provided above the push plate 48 is located at the lowest point of the obtuse arc groove provided on the limit block 47;

[0027] After the electric drive rotating wheel 41 rotates, the first crank 42 drives the second crank 43 to move forward as a whole. Due to the limitation of the limiting plate 45, the end of the second crank 43 connected to the pulley 49 only moves linearly in the limiting plate 45. At the same time, under the action of the pulley 49, the second crank 43 pushes the third crank 44 to move linearly. At the same time, the connecting frame 46 fixedly connected to the pulley 49 slides on the outer wall of the chassis 1, driving the bottom end of the push plate 48 to contact the slideway 6 and make a reciprocating motion.

[0028] When the locking protrusion provided on the push plate 48 is located at the lowest point of the obtuse arc groove provided on the limit block 47 and moves toward the highest point, the process of pushing the material is started. The torsion spring provided at the connection between the limit block 47 and the push plate 48 is tightened until the locking block is located at the highest point of the obtuse arc groove, so that there is an acute angle between the push plate 48 and the slide 6, so that the waste chips on the slide 6 can be pushed away more effectively. When the locking protrusion provided on the push plate 48 is located at the highest point of the obtuse arc groove provided on the limit block 47 and moves toward the lowest point, this process is the return state, and the torsion spring provided at the connection between the limit block 47 and the push plate 48 is opened, so that there is no resistance between the bottom end of the push plate 48 and the surface of the slide 6. Because the material of the push plate 48 is soft plastic, the bottom end will pass over the uncleaned waste until the locking block is located at the lowest point of the obtuse arc groove, so that there is an obtuse angle between the push plate 48 and the slide 6, and when the next reciprocating motion is made, the push plate 48 continues to push the waste into the recycling box 5;

[0029] The mechanism is provided with two sets of push plates 48, the purpose of which is to make the waste fall into the recycling box 5 more effectively through the alternating cooperation of the two sets of push plates 48, and at the same time play a role in continuously cleaning the slideway 6. When the first crank 42 and the second crank 43 move to the same horizontal line, the push plate 48 moves to the maximum distance, and the push plate 48 close to the recycling box 5 is close to the inner wall of the recycling box 5;

[0030] To sum up, the waste is pushed into the recycling box 5 through the pushing mechanism 4, and the function of the machine cover 3 is to prevent the fine waste dust in the chassis 1 from scattering and affecting the indoor air quality and causing harm to the health of the operator; the rotation of the rotating wheel 41 drives the first crank 42, the second crank 43, and the third crank 44 to cooperate with each other and continue to reciprocate under the limitation of the limit plate 45, and at the same time drives the pushing plate 48 to continuously push the processed waste of different sizes into the recycling box 5, and clean the inner wall of the slide 6.

[0031] The above is only a preferred implementation of the present application. The protection scope of the present application is not limited to the above embodiments. All technical solutions under this idea belong to the protection scope of the present application. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present application should also be regarded as the protection scope of the present application.
