Description

Technical Field

[0001] This utility model relates to the field of punching technology, and in particular to a material head punching device. Background Technology

[0002] Material end punching refers to the process of removing excess material generated during material processing, i.e., material ends. These material ends are usually generated by cutting, stamping or other forming processes. If they are not treated, they may lead to product defects or affect subsequent processing steps. Therefore, a punching device is needed to remove the material ends, so as to facilitate subsequent operations.

[0003] In a material head punching device with announcement number CN205058179U, an upper die base and a lower die base are provided on the frame. The bottom surface of the upper die base is provided with a plurality of punching dies arranged in a ring. The top surface of the lower die base is provided with a workpiece groove corresponding to the punching dies. A punching cylinder connected to the upper die base is provided on the frame above the upper die base. An ejection cylinder is provided on the frame below the lower die base. The ejection cylinder is connected to an ejector rod set in the workpiece groove. This utility model effectively solves the problem of low production efficiency caused by the single multiple punching method for separating workpieces of the whole mold component in the prior art. The material head punching device of this utility model can complete the separation of multiple workpieces in one punching, with high production efficiency, good product consistency, and high practical value.

[0004] However, the above-mentioned blanking device still has the following defects when in use: In the use of the above-mentioned existing technology, the blanking cylinder is turned on by a switch, the upper seat plate drives the upper die seat to move downward, the workpiece pressure plate first abuts against the workpiece and presses and fixes the workpiece, the upper die seat continues to move downward, and the cutter extends out from the through groove of the workpiece pressure plate, cutting all the workpieces off the whole die component at once. However, in actual use, the above operation does not have a cleaning function, so it is inconvenient to collect the blanks that have been punched off. If these blanks are not cleaned in time, they will not only pollute the working environment, but also reduce the efficiency of blanking. Utility Model Content

[0005] The purpose of this invention is to provide a material head punching device to solve the problem mentioned in the background art that the existing material head punching devices are inconvenient to collect the punched material head during use.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a material head punching device, comprising a base and a support base, wherein the support base is fixed at the top of the base;

[0007] An adjustment block is provided on one side of the top of the base, and an adjustment rod passes through the inside of the adjustment block. A servo motor is fixed to one end of the adjustment rod. A guide block is provided on the other side of the top of the base, and a guide rod passes through the inside of the guide block.

[0009] When using a cutting device for cutting a workpiece according to this technical solution, a cleaning mechanism is provided to facilitate the cleaning of the cutting head, thereby preventing it from polluting the working environment and improving processing efficiency.

[0010] Furthermore, the cleaning mechanism includes a collection box, which is located at the bottom of the base. A filter screen is hinged inside the collection box. An exhaust fan is installed inside the collection box at the bottom of the filter screen. A driven shaft is installed at the top of the exhaust fan. A driven bevel gear is fixed to the outer side of one end of the driven shaft. A driving bevel gear meshes with one side of the driven bevel gear. A driving shaft passes through the inside of the driving bevel gear. A cam is fixed to the outer side of the driving shaft. A cleaning motor is fixed to one side of the driving shaft. An adsorption tube is fixedly connected to the top of the collection box.

[0011] Furthermore, one end of the driven shaft extends into the interior of the exhaust fan, and a rotating impeller is provided inside the exhaust fan. One end of the driven shaft is fixedly connected to the rotating impeller inside the exhaust fan.

[0017] The cleaning motor drives the drive shaft to rotate, and the driven shaft rotates synchronously under the action of the drive bevel gear and the driven bevel gear. This causes the exhaust fan to generate suction force, and the collection box and suction tube facilitate the suction and collection of the material head after the workpiece is punched, thus avoiding pollution to the working environment. On the other hand, the cam hits the protrusion at the bottom of the filter screen, causing the filter screen to shake up and down, thereby preventing the filter screen from clogging and improving its working efficiency.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] Please see Figures 1-5 An embodiment of this utility model is provided: a material head punching device, including a base 1 and a support base 13. The support base 13 is fixed at the top of the base 1. An adjustment block 4 is provided on one side of the top of the base 1, and an adjustment rod 15 passes through the interior of the adjustment block 4. A servo motor 14 is fixed at one end of the adjustment rod 15. A guide block 2 is provided on the other side of the top of the base 1, and a guide rod 16 passes through the interior of the guide block 2. A cleaning mechanism 3 is provided at the bottom of the base 1.

[0028] The cleaning mechanism 3 includes a collection box 305, which is located at the bottom of the base 1. A filter screen 303 is hinged inside the collection box 305. An exhaust fan 301 is installed inside the collection box 305 at the bottom of the filter screen 303. A driven shaft 302 is installed at the top of the exhaust fan 301. A driven bevel gear 310 is fixed to the outer side of one end of the driven shaft 302. A driving bevel gear 309 meshes with one side of the driven bevel gear 310. A driving shaft 307 passes through the inside of the driving bevel gear 309. A cam 308 is fixed to the outer side of the driving shaft 307. A cleaning motor 304 is fixed to one side of the driving shaft 307. An adsorption tube 306 is fixedly connected to the top of the collection box 305.

[0029] One end of the driven shaft 302 extends into the interior of the exhaust fan 301. A rotating impeller is provided inside the exhaust fan 301. One end of the driven shaft 302 is fixedly connected to the rotating impeller inside the exhaust fan 301.

[0030] The filter screen 303 is arranged obliquely inside the collection box 305, and the bottom end of the filter screen 303 is attached with rubber protrusions.

[0031] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, during use, by starting the cleaning motor 304, the active bevel gear 309 rotates under the action of the drive shaft 307. Under the action of the driven bevel gear 310 and the driven shaft 302, the exhaust fan 301 generates suction force and collects the material head generated by the workpiece punching through the suction tube 306. On the other hand, the filter screen 303 shakes up and down under the action of the cam 308, thereby avoiding the phenomenon of filter screen 303 clogging and thus ensuring its filtration effect.

[0032] The top of the guide block 2 and the adjusting block 4 are fixed with a movable plate 12, and the top of the movable plate 12 is slidably provided with a lower mold 6. The top of the support base 13 is fixed with a punching cylinder 9, and the bottom of the punching cylinder 9 is provided with a horizontal plate 8. The bottom of the horizontal plate 8 is slidably provided with an upper mold 7. Two sliders 5 are fixed on one side of both the lower mold 6 and the upper mold 7, and the outer side of each slider 5 is provided with a sliding groove 10. Limiting mechanisms 11 are provided on both sides of both the lower mold 6 and the upper mold 7.

[0033] The limiting mechanism 11 includes two sets of fixing blocks 1101, and the two sets of fixing blocks 1101 are respectively fixed on one side of the horizontal plate 8 and the moving plate 12. The interior of each set of fixing blocks 1101 is slidably provided with a baffle 1105, and a limiting rod 1104 is fixed on one side of the baffle 1105. A pull rod 1102 is fixed on the other side of the baffle 1105. A return spring 1103 is evenly wound on the outer side of the pull rod 1102.

[0034] There are two sets of reset springs 1103, and each set of reset springs 1103 has two springs. The reset springs 1103 in each set are symmetrically distributed and are in a stretched state inside the fixed block 1101.

[0035] There are two sets of limit rods 1104, and each set of limit rods 1104 has two rods. Limit grooves are provided on the outer side of both sets of limit rods 1104.

[0036] Specifically, such as Figure 1 , Figure 3 , Figure 5 As shown, in use, by pulling the pull rod 1102 respectively, the limiting rod 1104 is retracted into the fixed block 1101, thereby releasing the limitation on the lower mold 6 and the upper mold 7, which makes it easier to replace them and thus improves their practicality.

[0037] Working principle: When using this utility model, firstly, when it is necessary to punch the material head on the workpiece, the workpiece is placed on the lower mold 6, and the servo motor 14 is started to make the adjusting rod 15 move horizontally, which in turn makes the adjusting block 4 move synchronously. Under the action of the guide block 2 and the guide rod 16, the moving plate 12 moves synchronously until the lower mold 6 moves directly below the upper mold 7. The punching cylinder 9 is started to make the horizontal plate 8 move downward, which makes the upper mold 7 move downward synchronously until one side of the upper mold 7 and one side of the lower mold 6 are in contact with each other, so as to facilitate punching the material head on the workpiece for subsequent operations.

[0038] Secondly, by starting the cleaning motor 304, the drive shaft 307 rotates. Simultaneously, the drive bevel gear 309 rotates synchronously. Because the drive bevel gear 309 and driven bevel gear 310 mesh, their rotation causes the driven bevel gear 309 to rotate synchronously, which in turn causes the driven shaft 302 to rotate synchronously. Since the driven shaft 302 is fixedly connected to the impeller inside the exhaust fan 301, the rotation of the driven shaft 302 simultaneously causes the impeller inside the exhaust fan 301 to rotate synchronously, thus enabling the exhaust fan to... 301 generates an adsorption force, which in turn generates an adsorption force inside the collection box 305. Under the action of the adsorption tube 306, it is easy to adsorb the material head cut off the workpiece and collect it inside the collection box 305. Through the above operation, the material head can avoid polluting the working environment, thereby improving its environmental friendliness and improving work efficiency. Meanwhile, the drive shaft 307 rotates, and at the same time, the cam 308 rotates synchronously. This causes the cam 308 to hit the rubber protrusion at the bottom of the filter screen 303, which in turn causes the filter screen 303 to shake up and down. Through the above operation, the filter screen 303 can be prevented from clogging during use, thereby improving its practicality.

[0039] Finally, when it is necessary to replace the lower mold 6 and upper mold 7 with different models according to actual usage, by pulling the two sets of pull rods 1102 respectively, the baffle 1105 slides inside the fixed block 1101. During the movement of the baffle 1105, on the one hand, it squeezes the return spring 1103, thereby compressing the return spring 1103 under the squeezing force, and on the other hand, it causes the limiting rod 1104 to move synchronously. During the continuous pulling of the pull rod 1102, the limiting rod 1104 is retracted into the fixed block 1101, thereby facilitating the release of the limitation on the lower mold 6 and upper mold 7, and pulling the lower mold 6 and upper mold 7 to make the slider 5 slide inside the slide groove 10, thereby facilitating the disassembly of the lower mold 6 and upper mold 7 for replacement. Through the above operation, it is convenient to replace the lower mold 6 and upper mold 7 with different models according to actual usage, thereby improving its flexibility to cope with different usage situations.
