Description

Technical Field

[0001] This utility model relates to the field of hardware stamping technology, specifically a hardware stamping part straightening mechanism. Background Technology

[0002] Metal stamping is a process that uses a punch press and dies to deform or break sheets of stainless steel, iron, aluminum, copper and other materials to achieve a certain shape and size. Shaping is a process that applies a small amount of deformation to a local area of ​​the workpiece after stamping to adjust the flatness, fillet radius and other aspects of the stamped part to meet the requirements of the workpiece.

[0003] The applicant discovered through a search that a Chinese patent discloses "A hardware stamping part straightening mechanism" with publication number "CN219426476U". This patent mainly includes a base plate, a vertical plate connected to the side of the base plate, a horizontal beam plate connected to the top of the vertical plate, a top plate slidably connected to the horizontal beam plate, a first telescopic member set on the top plate, a mounting frame connected to the bottom of the first telescopic member, a drive motor installed in the mounting frame, a straightening and grinding part connected to the bottom of the drive motor through a rotating shaft, a placement plate set on the base plate, and third telescopic members set on both sides of the placement plate to drive the mounting plate and clamping plate to move and quickly clamp and fix the hardware stamping parts. The clamping plate can be detachably installed on the mounting plate, making replacement convenient and quick. When it is necessary to clamp hardware stamping parts of different shapes and sizes, it is only necessary to replace the corresponding clamping plate and install it on the mounting plate. It can realize quick replacement of clamping plates to clamp different hardware stamping parts, resulting in better performance.

[0004] However, the following shortcomings still exist:

[0005] When the clamping plate interacts with the metal stamping part, friction and wear are likely to occur at the contact points, resulting in defects such as scratches and indentations on the surface. On the other hand, during the straightening process, the friction between the clamping plate and the metal stamping part continuously generates heat. At the same time, when the metal stamping part is ground and straightened, a large amount of heat is also generated, causing the metal stamping part to experience problems such as hardness changes and deformation due to overheating. Therefore, we propose a metal stamping part straightening mechanism. Utility Model Content

[0006] The purpose of this utility model is to provide a shaping mechanism for metal stamping parts.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a metal stamping part straightening mechanism, including a base plate, a workbench and a placement platform above the base plate, and a liquid return assembly inside the base plate. The liquid return assembly includes a guide plate, an inlet pipe one, an inlet pipe two, a liquid return tank, a filter box, a filter screen one, a filter screen two, a pump, and a pumping pipe. The guide plate is located above the workbench and has an inclined structure with a higher top and lower bottom. The inlet pipe one is symmetrically connected to both sides of the inner wall of the workbench. The inlet pipe one is connected to the liquid return tank through a lower through groove, the inlet pipe two, and the liquid return tank. The filter boxes are symmetrically installed on both sides of the inner wall of the liquid return tank. The workbench and base plate have a pull-out structure. Filter screen one and filter screen two are both located on the inner wall of the filter box. The mesh size of filter screen one is larger than that of filter screen two. The liquid pump is located above the return tank. The liquid pumping pipe is connected above the liquid pump. The workbench is equipped with a lubrication assembly, which includes a storage tank, a lubrication pump, a delivery pipe, a diverter pipe, a connecting pipe, and a nozzle. The storage tank is fixed to the inner wall of the workbench. The lubrication pump is located above the storage tank. The delivery pipe is connected to the diverter pipe and the connecting pipe above. The connecting pipe is connected through a guide plate, a clamping plate, and a nozzle. The nozzle is located on both sides of the inner wall of the clamping plate.

[0008] As a further embodiment of this utility model: clamping plates are installed on both sides inside the placement platform, and the clamping surface of the clamping plates is provided with several through holes 1. The clamping plates are connected to the placement platform through an electric telescopic rod 1, and the top surface inside the placement platform is provided with several through holes 2.

[0009] As a further embodiment of this utility model: a fixing plate is fixed below the placement platform, the fixing plate is connected to the placement platform through a gear one above, a gear two is provided on one side of the gear one, the gear one and the gear two are meshed with each other, and the gear two is connected to the drive end of the motor one.

[0010] As a further embodiment of this utility model: a bracket is fixed to the back of the workbench, a screw is provided below the bracket, the screw is connected to the drive end of the second motor, and a slider is sleeved on the outside of the screw.

[0011] As a further embodiment of this utility model: an electric telescopic rod is connected below the slider.

[0012] As a further embodiment of this utility model: the electric telescopic rod 2 is connected to the mounting plate and the fixing frame below, and a motor 3 is provided on one side of the fixing frame, and the drive end of the motor 3 is connected to the grinding wheel.

[0013] Compared with the prior art, the beneficial effects of this utility model by adopting the above technical solution are as follows:

[0014] 1. This utility model starts by a lubrication pump, which draws the cooling medium from the storage tank, introduces it into the distribution pipe through the delivery pipe, and then delivers it to the nozzle through the connecting pipe. The nozzle sprays the cooling medium into the clamping plate. Because there is a through hole on the side of the clamping plate, the cooling medium flows out and is evenly applied to the key parts of the clamped metal stamping parts, effectively reducing the heat generated by friction and preventing the parts from overheating and being damaged.

[0015] 2. In this invention, excess cooling medium drips through the through-hole two of the placement platform onto the guide plate. Through the inclined structure of the guide plate, the cooling medium flows smoothly into the inlet pipe one, then through the through groove and the inlet pipe two, and flows into the return tank. At this time, the cooling medium passes through the filter screen one and the filter screen two in the filter box in sequence. The filter screen one intercepts large particles of impurities, and then the filter screen two performs fine filtration to remove small impurities, ensuring that the cooling medium is clean and reusable. The filtered cooling medium is then transported back to the storage tank by the pump and the pump pipe, realizing recycling and reducing costs.

[0016] 3. With this utility model, the liquid storage tank can be pulled out of the base plate by the operator pulling the handle at the front end of the base plate, and then the filter box can be pulled out, so as to easily clean or replace filter screen one and filter screen two and maintain the efficient operation of the filtration system.

[0023] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand this utility model, but does not constitute a limitation on this utility model.

[0024] Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0025] Please see the appendix Figure 1 - Appendix Figure 4 This utility model discloses a hardware stamping part straightening mechanism, including a base plate 1, a worktable 2 and a placement table 3 arranged above the base plate 1, wherein, for example... Figure 1 , Figure 2 as well as Figure 4As shown, the base plate 1 is internally equipped with a liquid return assembly 101. The liquid return assembly 101 includes a guide plate 1101, an inlet pipe 1102, an inlet pipe 2 1103, a liquid return tank 1104, a filter box 1105, a filter screen 1106, a filter screen 2 1107, a pump 1108, and a pumping pipe 1109. The guide plate 1101 is located above the workbench 2 and has an inclined structure with a higher top and lower bottom. The inlet pipe 1102 is symmetrically connected to both sides of the inner wall of the workbench 2. The inlet pipe 1102 is connected to the liquid return tank 1104 through a lower through groove, the inlet pipe 2 1103, and the filter box 1105 is symmetrically installed on both sides of the inner wall of the liquid return tank 1104. The filter box 1105, the workbench 2, and the base plate 1 have a pull-out structure. Both filter screen 1106 and filter screen 1107 are disposed on the inner wall of filter box 1105. The mesh size of filter screen 1106 is larger than that of filter screen 1107. A pump 1108 is disposed above the return tank 1104. A suction pipe 1109 is connected above the pump 1108. A lubrication assembly 21 is installed inside the workbench 2. The lubrication assembly 21 includes a storage tank 2101, a lubrication pump 2102, a delivery pipe 2103, a diversion pipe 2104, a connecting pipe 2105, and a nozzle 2106. The storage tank 2101 is fixed to the inner wall of the workbench 2. The lubrication pump 2102 is disposed above the storage tank 2101. The delivery pipe 2103 is connected to the connecting pipe 2105 via the diversion pipe 2104 above. The connecting pipe 2105 passes through... The flow guide plate 1101, clamping plate 31, and liquid nozzle 2106 are connected. The liquid nozzle 2106 is located on both sides of the inner wall of the clamping plate 31. The lubrication pump 2102 is started, which delivers the cooling medium stored in the storage tank 2101 to the delivery pipe 2103. The cooling medium flows in the delivery pipe 2103 and then enters the distribution pipe 2104 and the connecting pipe 2105. The cooling medium is sprayed into the interior of the clamping plate 31 through the liquid nozzle 2106. Since the clamping plate 31 has a through hole 32 on its side, the sprayed cooling medium will flow out through the through hole 32 and be evenly coated on the clamped metal stamping parts, achieving effective lubrication of the key parts of the metal stamping parts, reducing the heat generated by friction, avoiding damage to the parts due to overheating, and also reducing noise generation. When the cooling medium has finished... After the coating is applied to the metal stamping parts, excess cooling medium drips into the second through-hole 34 in the placement platform 3. The cooling medium drips downwards through the second through-hole 34 and flows onto the guide plate 1101. Due to the inclined structure of the guide plate 1101, which is higher at the top and lower at the bottom, the cooling medium naturally flows along the guide plate 1101 to the first inlet pipe 1102. Then, the cooling medium enters the return tank 1104 through the through-slot and the second inlet pipe 1103. In the return tank 1104, the cooling medium enters the filter box 1105 and comes into contact with the first filter screen 1106 and the second filter screen 1107 in sequence. The first filter screen 1106 first performs preliminary filtration of the cooling medium, intercepting larger particulate impurities. Then, the second filter screen 1107 performs secondary fine filtration of the cooling medium.Removing smaller particulate impurities effectively removes various particulate impurities that may have entered the cooling medium during use, ensuring its cleanliness and making it usable again. Subsequently, the pump 1108 is activated, drawing the filtered cooling medium from the return tank 1104 and transporting it to the extraction pipe 1109. The cooling medium then re-enters the storage tank 2101 through the extraction pipe 1109, achieving the recycling of the cooling medium and reducing its usage cost. As the filter box 1105 is used for longer periods, its filtration efficiency is affected. At this point, the operator pulls the handle on the front of the base plate 1 to remove the storage tank 2101 from the base plate 1, and then pulls the filter box 1105 to remove it from the storage tank 2101. This facilitates cleaning or replacement of filter screens 1106 and 1107, ensuring the efficient operation of the filtration system.

[0026] In the first embodiment, clamping plates 31 are installed on both sides inside the placement platform 3. The clamping surfaces of the clamping plates 31 are provided with several through holes 32. The clamping plates 31 are connected to the placement platform 3 via an electric telescopic rod 33. The top surface inside the placement platform 3 is provided with several through holes 34.

[0027] Specifically, the position between the clamping plate 31 and the metal stamping part is adjusted by the telescopic movement of the electric telescopic rod 33, so that it can be clamped and fixed according to the size of the metal stamping part. While clamping the metal stamping part, the cooling medium inside the clamping plate 31 flows out through the through hole 32 and is applied to the surface of the metal stamping part. When the excess cooling medium drips into the through hole 34, the cooling medium drips down and is collected.

[0028] In the second embodiment, a support 8 is fixed behind the workbench 2, and a screw 9 is provided below the support 8. The screw 9 is connected to the drive end of the motor 10, and a slider 11 is sleeved on the outside of the screw 9.

[0029] The cooling medium is a water-based coolant, and the water-based coolant formula is: 90% deionized water, 6% borate ester rust inhibitor, 3.5% thiophosphate extreme pressure agent, and 0.5% organosilicon defoamer.

[0030] Specifically, driven by motor 10, slider 11 slides outside screw 9. The position of the lower component is adjusted by sliding slider 11, and the position between grinding wheel 16 and metal stamping part is adjusted so that different parts of metal stamping part are ground.

[0031] Working principle:

[0032] First, the metal stamping part is placed in the placement table 3. At this time, the electric telescopic rod 33 adjusts the position between the clamping plate 31 and the metal stamping part. Then, the motor 10 starts and drives the screw 9 to rotate, so that the slider 11 sleeved on the screw 9 slides axially. Since the grinding wheel 16 is installed below the slider 11, the position of the grinding wheel 16 is adjusted when the slider 11 slides, so that it can be aligned with different parts of the metal stamping part to achieve efficient grinding. The electric telescopic rod 12 drives the mounting plate 13, the fixing frame 14 and the grinding wheel 16 to move closer to the position of the metal stamping part. At the same time, the motor 15 drives the grinding wheel 16 to grind and straighten the metal stamping part. While grinding the metal stamping part, the motor 7 drives the gear 6 to rotate and mesh with the gear 5, so that the gear 5 rotates on the fixing plate 4, thus driving the rotation of the placement table 3 to achieve the angle adjustment of the metal stamping part.

[0033] The lubrication pump 2102 starts, drawing cooling medium from the storage tank 2101. The medium is then sprayed through the delivery pipe 2103, the branch pipe 2104, and the connecting pipe 2105, and sprayed into the clamping plate 31 through the nozzle 2106. It is then applied to key parts of the metal stamping parts through the first through-hole 32 to reduce frictional heat and noise. Excess cooling medium flows through the second through-hole 34 of the placement platform 3, along the guide plate 1101, into the first inlet pipe 1102, and through the through-slot and the second inlet pipe 1103 into the return tank 1104. Inside the return tank 1104... The cooling medium passes sequentially through filter screen 1106 in filter box 1105 to intercept large particles and filter screen 1107 to filter out small impurities, thus achieving cleaning. The liquid pump 1108 is started to pump the filtered cooling medium back to the storage tank 2101 for recycling. When the filtration effect of filter box 1105 deteriorates, the operator pulls the handle at the front end of the base plate 1 to pull out the storage tank 2101 and then pulls out the filter box 1105 to clean or replace the filter screen, maintaining the efficient operation of the system. At this point, the entire workflow is complete.
