Description

Technical Field

[0001] The utility model relates to the technical field of stacking devices, in particular to a stacking device used in a pressing process of tungsten carbide alloy blanks. Background Art

[0002] Tungsten carbide is an important hard alloy that is widely used in engineering frames, such as the disc cutters used in shield machines. The addition of tungsten carbide can effectively improve rock breaking performance. For this reason, tungsten carbide is widely used. After the tungsten carbide is pressed, a stacking device is required to stack the tungsten carbide.

[0003] Publication number CN218753612U discloses a stacking device for the pressing process of tungsten carbide alloy billets, including a receiving tray, a material guide ramp, and a receiving plate arranged at the end of the material guide ramp, the receiving plate is provided with a limit plate for limiting the tungsten carbide alloy billet, a push plate is provided on one side of the receiving plate, the end of the push plate away from the receiving plate is connected to a pushing mechanism, a cross moving platform is provided on the side of the receiving plate away from the pushing mechanism, the receiving tray is arranged on the cross moving platform, one end of the receiving plate is above the receiving tray, and the receiving plate is moved on the receiving tray under the action of the cross moving platform. Although this type of palletizing device realizes the orderly palletizing of tungsten carbide alloy billets and realizes the automation of the palletizing process at a low cost, when the tungsten carbide alloy billets slide on the top surface of the receiving tray, the inner wall of the receiving tray will be worn and stained with stubborn stains during long-term use, which will cause the inner wall of the receiving tray to be rough and not smooth. In this way, during the process of stacking the tungsten carbide alloy billets, the tungsten carbide alloy billets are prone to displacement and rotation when sliding on the inner wall of the receiving tray for palletizing, thereby affecting the palletizing effect. In addition, the rough inner wall is also prone to wear on the tungsten carbide alloy billets, which needs to be improved. Utility Model Content

[0004] The purpose of this utility model is to solve the technical problems raised in the above background technology.

[0005] The utility model adopts the following technical scheme: a stacking device for a tungsten carbide alloy blank pressing process comprises a base, a mounting plate is fixedly installed on the top surface of the base, a cylinder is fixedly installed on the surface of the mounting plate, a material receiving tray is installed on the output end of the cylinder, a mounting frame is fixedly installed on the side of the base, an electric push rod is fixedly installed on the side of the mounting frame, a push plate is installed on the output end of the electric push rod, a material receiving plate is fixedly installed on the top surface of the mounting frame, the back side of the material receiving plate is connected to a material guide ramp, a long rod is provided through the side of the material receiving tray, a movable plate is fixedly installed on one end of the long rod, a short rod is provided through the top of the long rod, a stop block is fixedly installed on one end of the short rod, a bottom plate is fixedly installed on the other end of the short rod, sandpaper is fixedly installed on the bottom surface of the bottom plate, and a spring is sleeved on the surface of the short rod.

[0006] Preferably, a rubber pad is fixedly installed on the side of the movable plate, and the material of the rubber pad is natural rubber. Here, the tungsten carbide alloy blank can be protected.

[0007] Preferably, the short rod and the long rod are slidably connected, and the long rod and the receiving tray are slidably connected.

[0008] Preferably, the mounting frame is an "L"-shaped structure, and the sandpaper fits against the inner wall of the receiving tray.

[0009] Preferably, the cylinders are symmetrically distributed on the surface of the mounting plate, and there are two groups of cylinders.

[0010] Preferably, a limiting mechanism is fixedly mounted on the inner side of the receiving plate. The limiting mechanism comprises a circular groove formed on the inner side of the receiving plate, a magnet fixedly mounted on the inner wall of the circular groove, and a circular block provided on the inner wall of the circular groove, a limiting pad fixedly mounted on one end of the block. In this manner, tungsten carbide alloy billets can be pre-stacking.

[0011] Preferably, the material of the limiting pad is natural rubber, and the material of the round block is ferritic stainless steel. Here, the service life of the round block can be increased.

[0012] Compared with the prior art, the advantages and positive effects of the present invention are:

[0013] 1. In the present invention, when actually used, the tungsten carbide alloy blank enters through the material guide ramp, and then the tungsten carbide alloy blank enters the material receiving plate along the material guide ramp until the tungsten carbide alloy blank is squeezed by the rubber pad. At this time, the tungsten carbide alloy blank can be blocked by the extrusion of the rubber pad until the tungsten carbide alloy blank is arranged in a row in the material receiving plate. At this time, the tungsten carbide alloy blank can be limited, and then the electric push rod drives the push plate to push the tungsten carbide alloy blank to slide on the material receiving plate until the tungsten carbide alloy blank is pushed into the material receiving tray. Then the tungsten carbide alloy blank slides on the material receiving tray until it is completely fitted with the material receiving tray. At this time, the stacking of the tungsten carbide alloy blank can be completed. At the same time, when the inner wall of the receiving tray is relatively rough and affects the sliding of the tungsten carbide alloy blank, the staff only needs to push the long rod, and the long rod then drives the movable plate to move, and the movable plate then drives the bottom plate to move, and the bottom plate then drives the sandpaper to rub the inner wall of the receiving tray. At this time, the inner wall of the receiving tray can be polished. At the same time, due to the elastic force of the spring, the spring can drive the bottom plate to move downward, and the bottom plate then drives the sandpaper to stick to the inner wall of the receiving tray. The sandpaper provided in the utility model can polish the receiving tray, which can improve the smoothness of the receiving tray, and the elastic force of the spring can also make the sandpaper stick to the inner wall of the receiving tray, which can improve the polishing effect and has high practicality.

[0014] 2. In the present invention, during actual use, the tungsten carbide alloy blank can be blocked by the extrusion of the limit pad, so that the tungsten carbide alloy blank can be arranged in the receiving plate. At the same time, when the limit pad is severely worn, the staff only needs to pull the limit pad outward, and the limit pad then drives the round block to leave the round groove. At this time, the limit pad can be removed. At the same time, since the material of the round block is ferritic stainless steel, the magnet can absorb the round block, which can effectively limit the limit pad. In this way, when installing the limit pad, it is only necessary to fit the round block to the magnet to install the limit pad, which effectively improves maintenance efficiency.

At this time, the tungsten carbide alloy billet can be blocked by the extrusion of the rubber pad 17 until the tungsten carbide alloy billet is arranged in a row in the receiving plate 8. At this time, the tungsten carbide alloy billet can be limited, and then the electric push rod 6 drives the push plate 7 to push the tungsten carbide alloy billet to slide on the receiving plate 8 until the tungsten carbide alloy billet is pushed into the receiving tray 4, and then the tungsten carbide alloy billet slides on the receiving tray 4 until it is completely fitted with the receiving tray 4.

[0028] Example 2

[0029] See also Figure 5-6The inner side of the receiving plate 8 is fixedly installed with a limiting mechanism, which includes a circular groove 18. The circular groove 18 is opened on the inner side of the receiving plate 8. A magnet 19 is fixedly installed on the inner wall of the circular groove 18.

The tungsten carbide alloy blank can be blocked by the extrusion of the limiting pad 21, so that the tungsten carbide alloy blank can be arranged on the receiving plate. In the plate 8, when the limit pad 21 is severely worn, the staff only needs to pull the limit pad 21 outward, and the limit pad 21 then drives the round block 20 to leave the circular groove 18. At this time, the limit pad 21 can be removed.

[0030] Working principle: The tungsten carbide alloy billet enters through the material guide ramp 9, and then the tungsten carbide alloy billet enters the receiving plate 8 along the material guide ramp 9 until the tungsten carbide alloy billet is squeezed by the rubber pad 17. At this time, the tungsten carbide alloy billet can be blocked by the extrusion of the rubber pad 17 until the tungsten carbide alloy billet is arranged in a row in the receiving plate 8. At this time, the tungsten carbide alloy billet can be limited, and then the electric push rod 6 drives the push plate 7 to push the tungsten carbide alloy billet to slide on the receiving plate 8 until the tungsten carbide alloy billet is pushed into the receiving tray 4. Then the tungsten carbide alloy billet slides on the receiving tray 4 until it is completely fitted with the receiving tray 4. At this time, the stacking of the tungsten carbide alloy billet can be completed. At the same time, when the inner wall of the receiving tray 4 is relatively rough and affects the sliding of the tungsten carbide alloy billet, the staff only needs to push the long rod 10, and the long rod 10 then drives the movable plate 11 to move, and the movable plate 11 then drives the bottom plate 14 to move The bottom plate 14 then drives the sandpaper 15 to rub the inner wall of the receiving tray 4, and the inner wall of the receiving tray 4 can be polished at this time. At the same time, due to the elastic force of the spring 16, the spring 16 can drive the bottom plate 14 downward to move, and the bottom plate 14 then drives the sandpaper 15 to close to the inner wall of the receiving tray 4, which can achieve the polishing effect. The tungsten carbide alloy blank can be blocked by the extrusion of the limit pad 21, thereby arranging the tungsten carbide alloy blank in the receiving plate 8. At the same time, when the limit pad 21 is seriously worn, the staff only needs to pull the limit pad 21 outward, and the limit pad 21 then drives the round block 20 to leave the circular groove 18. At this time, the limit pad 21 can be removed. At the same time, since the material of the round block 20 is ferritic stainless steel, the magnet 19 can attract the round block 20, which can effectively limit the limit pad 21. In this way, when installing the limit pad 21, it is only necessary to fit the round block 20 into the magnet 19 to install the limit pad 21, which effectively improves the maintenance efficiency.
