Description

Technical Field

[0001] The utility model relates to the technical field of punching machine tools, in particular to a waste material removing device for punching machine tools. Background Art

[0002] A punch press is a stamping press. In national production, the stamping process has the advantages of saving materials and energy, high efficiency, low technical requirements for operators, and the ability to make products that cannot be achieved by mechanical processing through various mold applications. Therefore, its use is becoming more and more extensive. Stamping production is mainly for sheet metal. Through molds, it can make blanking, punching, forming, drawing, trimming, fine blanking, shaping, riveting and extrusion parts, etc., which are widely used in various fields. For example, the switches, sockets, cups, cupboards, plates, computer cases, and even missile aircraft we use... There are many accessories that can be produced by punching machines through molds. Among them, single-stroke stamping equipment is more commonly used. During the stamping process, a large amount of waste will accumulate on the stamping table, and too much waste accumulation will affect the normal use of stamping.

[0003] For example, the Chinese patent publication number CN213793652U discloses a waste removal device for a stamping machine, which belongs to the technical field of stamping machines, and includes a box body, the front of the box body is fixedly connected to the back of the box body, the upper surface of the box body is fixedly connected to the lower surface of the support plate, the upper surface of the support plate is fixedly connected to the lower surface of the stamping structure, and the bottom end of the stamping structure is fixedly connected to the upper surface of the movable mold. The waste removal device for a stamping machine, by setting a transmission belt body, a slide groove and a slider, two threaded rods drive two threaded sleeves to start moving toward each other, the two threaded sleeves drive the telescopic plate to move to the right through the connecting block and the fixed block, and the pressing plate drives the slider to slide in the slide groove at the same time, and then the pressing plate maintains a stable rightward movement and starts to squeeze the waste. Under the joint action of the two pressing plates, the waste is squeezed into a square. This method can compress the waste when in use, reduce the space it occupies, and facilitate the subsequent processing of the collected waste.

[0004] The existing technology has the following problems:

[0005] The cleaning device only considers the waste located on the left and right sides of the plate, but does not consider the waste located on the front and back sides of the plate. This leads to requirements for the mold by the cleaning device, that is, the waste after stamping is only located on the left and right sides of the plate, which reduces the applicability of the product.

DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] like Figure 1 As shown, a waste removal device for a stamping machine tool comprises a workbench 1, an upper surface of the workbench 1 is fixedly connected to a vertical table 2 near the left and right sides, a stamping mechanism 3 is movably installed on the inner upper surface of the vertical table 2, a moving mechanism 4 is fixedly connected to the inner front and rear sides of the workbench 1, and a cleaning mechanism 5 is fixedly connected to the upper side of the workbench 1 near the left rear side.

[0027] It should be noted that the moving mechanism 4 contains components such as a moving assembly and a moving mold, and the moving assembly drives the moving mold to move up and down to achieve the purpose of stamping.

[0028] like Figure 2 , Figure 3 As shown, the moving mechanism 4 includes a first motor 41, the front side of the first motor 41 is fixedly connected to the inner front surface of the workbench 1 near the lower left side, the output end of the first motor 41 is fixedly connected to a bent rod 42, and two bent rods 42 are symmetrically distributed on the left and right, both ends of the bent rod 42 are rotatably connected to the front and back surfaces of the inner side of the workbench 1, the outer sides of the two bent rods 42 are rotatably connected to a number of evenly distributed connecting rods 43, the upper ends of the connecting rods 43 are rotatably connected to a fixed platform 44, the outer side of the fixed platform 44 is movably sleeved on the inner side of the upper wall of the workbench 1 near the upper side, and a fixed mold 45 is fixedly connected to the axis center of the upper surface of the fixed platform 44.

[0029] It should be noted that the first motor 41 drives the curved rod 42 located on the left side to rotate, and when the curved rod 42 rotates, it drives the lower end of the connecting rod 43 to move downward, thereby driving the fixed mold 45 to move up and down.

[0030] like Figure 3As shown, four rectangularly distributed first limiting rods 46 are movably sleeved on the left and right sides of the fixing platform 44 , and first springs 47 are movably sleeved on the outer walls of the four first limiting rods 46 , and the first springs 47 are located at the lower side of the fixing platform 44 .

[0031] It should be noted that the first limit rod 46 is used to limit the fixed platform 44, so that the fixed platform 44 can only move up and down to prevent the moving position of the fixed platform 44 from being offset. The first spring 47 pushes the fixed platform 44 upward to prevent the fixed mold 45 from moving during stamping, affecting the quality control after stamping.

[0032] like Figure 3 As shown, the outer walls of the two bent rods 42 are fixedly connected to positions near the rear ends thereof, and the side surfaces of the sprockets 48 are meshedly connected to chains 49 .

[0033] It should be noted that when the left curved rod 42 rotates, it drives the left sprocket 48 to rotate, and the chain 49 causes the two sprockets 48 to rotate synchronously in the same direction, thereby causing the two curved rods 42 to rotate synchronously in the same direction, so that the left and right sides of the fixed platform 44 are subjected to balanced force.

[0034] like Figure 1 , Figure 4 and Figure 5 As shown, the cleaning mechanism 5 includes a second motor 51, the left and right sides of the second motor 51 are fixedly connected to a boss on the upper surface of the workbench 1 near the left rear side, the output end of the second motor 51 is fixedly connected to a linkage shaft, the outer wall of the linkage shaft is fixedly connected to a first winding wheel 52 near the left and right ends, the upper surface of the workbench 1 near the rear side is slidably connected to a push plate 511, the inner sides of the two first winding wheels 52 are both wound with a first traction rope, the front end of the first traction rope is fixedly connected to the left and right sides of the push plate 511 near the rear side, and the left and right sides of the workbench 1 near the rear side are Two left-right symmetrical second winding wheels 53 are rotatably connected to the boss, and two left-right symmetrical fixed pulleys 55 are rotatably connected to the bosses on the left and right sides of the workbench 1 near the front side. The inner sides of the two second winding wheels 53 are wound with second traction ropes, and the upper ends of the second traction ropes are fixedly connected to the left and right sides of the push plate 511 near the front side, and the inner sides of the second traction ropes are overlapped on the front sides of the fixed pulleys 55. The two first winding wheels 52 and the two fixed pulleys 55 are fixedly connected to the side away from the push plate 511 with gears 54, and the two gears 54 on the same side are meshed and connected together.

[0035] It should be noted that the second motor 51 drives the first winding wheel 52 to rotate. When the first winding wheel 52 rotates, it drives the gear 54 located on the first winding wheel 52 to rotate, and then drives the second winding wheel 53 to rotate. The rotation directions of the first winding wheel 52 and the second winding wheel 53 are opposite, so that when the first winding wheel 52 releases the first traction rope, the second winding wheel 53 retracts the second traction rope, and vice versa, the second winding wheel 53 releases the second traction rope. Depending on the state of the two traction ropes, the push plate 511 is driven to move back and forth on the workbench 1 to push the waste on the workbench 1 to the front side.

[0036] like Figure 4 As shown, two second limit rods 59 symmetrically on the left and right are movably sleeved on the lower side of the push plate 511, the rear end of the second limit rods 59 is fixedly connected to the mechanism platform 56, and the second limit rods 59 are located in the grooves on the left and right sides of the mechanism platform 56, and the outer walls of the two second limit rods 59 are movably sleeved with third springs 510, and the third springs 510 are located on the front side of the push plate 511.

[0037] It should be noted that the third spring 510 pushes the lower side of the push plate 511, causing the push plate 511 to move forward and drive the mechanism platform 56 forward. When the front end of the second limit rod 59 presses against the inner front surface of the workbench 1, the mechanism platform 56 is fixed, and the push plate 511 can continue to move forward.

[0038] like Figure 4 As shown, a plurality of evenly distributed second springs 57 are fixedly connected to the inner lower surface of the mechanism platform 56 , and a top plate 58 is fixedly connected to the upper side of the second spring 57 .

[0039] It should be noted that when the mechanism table 56 moves forward and moves to the opening of the upper wall of the workbench 1, the second spring 57 pushes the top plate 58 upward, causing the outer side of the top plate 58 to be movably sleeved into the inner side of the upper wall of the workbench 1, thereby preventing waste slag on the upper side of the workbench 1 from entering the inner side of the workbench 1.

[0040] like Figure 4 As shown, the top plate 58 is in the shape of a right-angled trapezoid, and the inclined surface of the top plate 58 faces the rear side.

[0041] It should be noted that the shape of the top plate 58 is such that when the push plate 511 drives the mechanism table 56 to reset, the inner downward edge of the upper wall of the workbench 1 can push the inclined surface of the top plate 58, causing the top plate 58 to move downward, so that the top plate 58 enters the inner side of the mechanism table 56.

[0042] The working principle of the utility model is as follows: first, the second motor 51 drives the first winding wheel 52 to rotate. When the first winding wheel 52 rotates, it drives the gear 54 located on the first winding wheel 52 to rotate, and then drives the second winding wheel 53 to rotate. The first winding wheel 52 and the second winding wheel 53 rotate in opposite directions, so that when the first winding wheel 52 releases the first traction rope, the second winding wheel 53 retracts the second traction rope, and vice versa, the second winding wheel 53 releases the second traction rope, and relies on the state of the two traction ropes to drive the push plate 511 to move back and forth on the workbench 1, and push the waste on the workbench 1 to the front side. The third spring 510 pushes the lower side of the push plate 511, so that when the push plate 511 moves forward, the mechanism is driven When the platform 56 moves forward, when the front end of the second limit rod 59 presses against the inner front surface of the workbench 1, the mechanism platform 56 is fixed, and the push plate 511 can continue to move forward. When the mechanism platform 56 moves forward, it moves to the opening of the upper wall of the workbench 1, and the second spring 57 pushes the top plate 58 upward, so that the outer side of the top plate 58 is movably sleeved into the inner side of the upper wall of the workbench 1 to prevent the waste residue on the upper side of the workbench 1 from entering the inner side of the workbench 1. The shape of the top plate 58 causes the push plate 511 to drive the mechanism platform 56 to reset, and the lower rear edge of the inner side of the upper wall of the workbench 1 can push the inclined surface of the top plate 58, causing the top plate 58 to move downward, so that the top plate 58 enters the inner side of the mechanism platform 56 and moves down to the workbench through the fixed mold 45. 1, the second motor 51 drives the first winding wheel 52 to rotate, so that the first traction rope and the second traction rope pull the push plate 511, causing the push plate 511 to move left and right, push the waste forward, and keep the upper side of the workbench 1 clean. The top plate 58 closes the inner side of the upper wall of the workbench 1 to prevent the waste from entering the interior of the workbench 1, thereby cleaning up all the waste, and cleaning up the waste on the four sides of the fixed mold 45, thereby improving the applicability of the device. Finally, the first motor 41 drives the curved rod 42 on the left side to rotate. When the curved rod 42 rotates, it drives the lower end of the connecting rod 43 to move down, thereby driving the fixed mold 45 to move up and down. The first limit rod 46 is used to limit the fixed table 44, causing the fixed table 44 can only move up and down to avoid the movement position of the fixed table 44 from being offset. The first spring 47 pushes the fixed table 44 upward to avoid the fixed mold 45 from moving during stamping and affecting the quality control after stamping. When the curved rod 42 on the left side rotates, it drives the sprocket 48 on the left side to rotate. Relying on the chain 49, the two sprockets 48 rotate synchronously in the same direction, and then the two curved rods 42 rotate synchronously in the same direction, so that the left and right sides of the fixed table 44 are balanced. The curved rod 42 is driven to rotate by the first motor 41, and then the fixed table 44 moves up and down, so that the fixed mold 45 moves down to the inner side of the workbench 1, so as to achieve the purpose of demoulding, while avoiding affecting the work of the cleaning mechanism 5 and hindering the movement of the push plate 511.
