Description

Technical Field

[0001] The present invention relates to the technical field of stamping part processing, and particularly to an efficient continuous production device for hardware stamping parts. Background Art

[0002] Hardware: Parts processed from steel or some non-ferrous metals. Processing methods: cold / hot stamping, extrusion, rolling, welding, cutting, etc., and also include some other processes, with a relatively broad definition.

[0004] Hardware stamping parts are metal stamping parts that constitute various components. Among hardware stamping parts, some directly become components after stamping, and some need to go through processes such as welding, or machining, or painting, etc. after stamping to become device components. After the stamping parts are formed, their surfaces need to be polished to ensure that there are no burrs on the surfaces and prevent the burrs from scratching the pipe fittings.

[0005] However, there are some problems with the current hardware stamping parts during grinding and polishing. Currently, when stamping parts are ground and polished, most are manually ground with grinding tools. The efficiency of manual grinding is low, and when workers work in the grinding environment for a long time, it is easy to inhale the debris during grinding into the body, causing harm to the body of the grinding workers. However, due to the high-speed rotation of the grinding tool during the grinding of stamping parts, the stamping parts shift and shake, resulting in insufficient grinding of the stamping parts by the grinding tool.

[0031] Compared with the prior art, the present invention provides a first telescopic rod 51, a first clamping plate 56, a second clamping plate 512 and other mechanisms, and the stamping part is transported to the inside of the protective plate 2 by the existing conveying device, and the stamping part follows the rotating shaft 515 inside the strip groove 514 on the side wall of the first clamping plate 56 and enters between the first clamping plates 56. Under the gravity of the stamping part, the base 52 moves downward, and the base 52 drives the hydraulic rod 53, the first spring 57, and the second spring 59 to contract. At the same time, the second spring 59 pushes the slider 58 to slide downward, and the slider 58 drives the connecting rod 510 to deflect, thereby driving the first support rod 511 to lift upward, thereby driving The first clamping plate 56 and the second clamping plate 512 rise upward, and the push rod 55 cannot slide left and right due to the limiting action of the slide groove 54, so that the push rod 55 moves downward, and under the limiting action of the push rod 55 and the connecting rod 510, the first clamping plate 56 deflects along the connection point of the push rod 55 and the connecting rod 510.

[0032] Reference Figures 1 - 4, a return flow mechanism 6 for guiding water flow is provided on the base 1 and the protection plate 2. The return flow mechanism 6 includes an inner cavity 61 opened inside the base 1. A plurality of drain ports 62 are opened at the upper end of the base 1. The plurality of drain ports 62 communicate with the inner cavity 61. A piston plate 63 is slidably installed inside the inner cavity 61. The bottom end of the ejector rod 55 is fixedly connected to the upper end of the piston plate 63. A plurality of water guide ports 64 are opened on the piston plate 63. A plurality of water guide pipes 69 are fixedly connected between the base 1 and the protection plate 2. A plurality of spray heads 610 are fixedly installed on the inner wall of the protection plate 2. The two ends of the water guide pipe 69 communicate with the inner cavity 61 and the spray heads 610 respectively.

[0033] In the embodiment of the present application, the present invention forms a compression on the air in the inner cavity 61 by setting mechanisms such as the drain port 62, the piston plate 63, and the water guide port 64. The piston plate 63 slides downward in the inner cavity 61 under the drive of the ejector rod 55, so that the cooling water in the inner cavity 61 is squeezed into the spray heads 610 from the water guide pipe 69, and the cooling water is sprayed from the plurality of spray heads 610 onto the stamping part to cool the stamping part, preventing the stamping part from being damaged due to overheating during grinding. The rinsed cooling water returns to the inner cavity 61 again from the drain port 62 for reuse, getting rid of the disadvantage of additionally setting a driving device in the cooling device in the traditional technology, realizing the self-driving of the cooling device, and reusing the water resources.

[0034] Refer to Figure 2 , Figure 4 , a plurality of fourth springs 68 are fixedly connected to the bottom wall of the inner cavity 61. The top ends of the plurality of fourth springs 68 are fixedly installed with a floating plate 65. A plurality of water outlet ports 66 are opened on the floating plate 65. A plurality of blocking blocks 67 are fixedly installed on the upper end of the floating plate 65.

[0035] In the embodiment of the present application, the present invention forms a compression on the fourth spring 68 by setting mechanisms such as the fourth spring 68, the floating plate 65, and the water outlet port 66. The cooling water flows downward from the water guide port 64 and then flows into the cooling water in the inner cavity 61 through the water outlet port 66. When the piston plate 63 slides downward in the inner cavity 61, it drives the floating plate 65 to move downward, compressing the fourth spring 68. With the support of the fourth spring 68 and the self-tension of the cooling water on the floating plate 65, the floating plate 65 and the piston plate 63 are closely attached together. The blocking block 67 on the floating plate 65 blocks the water guide port 64 on the piston plate 63, preventing the cooling water from overflowing from the water guide port 64 during the extrusion process.

[0036] Refer to Figures 1 - 5 , an adsorption mechanism 7 for cleaning debris is provided inside the protection plate 2. The adsorption mechanism 7 includes a plurality of second support rods 71 hinged to the upper end of the base 1. Magnetic plates 72 are hinged to the top ends of the plurality of second support rods 71. A fifth spring 73 is fixedly connected between the two second support rods 71. Two second telescopic rods 74 are fixedly connected between the first clamping plate 56 and the magnetic plate 72.

[0037] In the embodiment of the present application, the present invention sets up a second support rod 71, a magnetic plate 72, a fifth spring 73 and other mechanisms. When the first clamping plate 56 slides, it drives the second telescopic rod 74 to support the magnetic plate 72 upward, so that the magnetic plate 72 rises above the upper side of the first clamping plate 56. The debris generated by the stamping parts during grinding is flushed to the surface of the magnetic plate 72 under the flushing of the water flow, and then the debris is adsorbed to prevent the debris from splashing and causing dust pollution to the air.

[0038] Reference Figure 2 , the first clamping plate 56 is set to a C-shaped structure.

[0039] In the embodiment of the present application, the first clamping plate 56 is set as a C-shaped structure, so that the first clamping plate 56 can clamp and fix stamping parts of different specifications, and the second clamping plate 512 inside the C-shaped structure can clamp stamping parts of smaller specifications.

[0040] Reference Figure 2 The first clamping plate 56 is made of high manganese steel.

[0041] In the embodiment of the present application, high manganese steel has the characteristics of high strength and wear resistance, so that the first clamping plate 56 will not be worn due to friction between the first clamping plate 56 and the stamping part during the process of clamping the stamping part.

[0042] Reference Figure 2 The areas of the piston plate 63 and the floating plate 65 are equal to the cross-section of the inner cavity 61, and the materials of the piston plate 63 and the floating plate 65 are butadiene rubber.

[0043] In the embodiment of the present application, the areas of the piston plate 63 and the floating plate 65 are set to be equal to the cross-section of the inner cavity 61, so that the piston plate 63 and the floating plate 65 completely seal the inner cavity 61 when they are in close contact; butadiene rubber has the characteristics of high elasticity and wear resistance, so that the piston plate 63 and the floating plate 65 can be in close contact with the inner wall of the inner cavity 61 under the action of their own elastic force, so that a sealed state is formed in the inner cavity 61.

[0044] Working principle:

[0045] The stamping part is transported to the inside of the protective plate 2 by the existing conveying device, and the stamping part enters between the first clamping plates 56 along the rotating shaft 515 inside the strip groove 514 on the side wall of the first clamping plate 56. Under the gravity of the stamping part, the base 52 moves downward, and the base 52 drives the hydraulic rod 53, the first spring 57, and the second spring 59 to contract. At the same time, the second spring 59 pushes the slider 58 to slide downward, and the slider 58 drives the connecting rod 510 to deflect, thereby driving the first support rod 511 to lift upward, thereby driving the first clamping plate 56 and the second clamping plate 59 to move downward. 12 rises upward, and the push rod 55 cannot slide left and right under the limiting effect of the slide groove 54, so that the push rod 55 moves downward, and under the limiting effect of the push rod 55 and the connecting rod 510, the first clamping plate 56 deflects along the connection point of the push rod 55 and the connecting rod 510, and several first clamping plates 56 fix the stamping parts at the same time, and the second clamping plate 512 can clamp the stamping parts with smaller specifications. The piston plate 63 slides downward in the inner cavity 61 under the drive of the push rod 55, and the piston plate 63 squeezes the air in the inner cavity 61 , the cooling water flows from the water guide port 64 to the bottom, and then flows into the cooling water in the inner cavity 61 through the water outlet 66. When the piston plate 63 slides downward in the inner cavity 61, it drives the floating plate 65 to move downward, compressing the fourth spring 68. As the fourth spring 68 and the tension of the cooling water itself support the floating plate 65, the floating plate 65 and the piston plate 63 are tightly attached together. The blocking block 67 on the floating plate 65 blocks the water guide port 64 on the piston plate 63 to prevent the cooling water from overflowing from the water guide port 64 during the squeezing process, thereby allowing the cooling water in the inner cavity 61 to flow out of the water guide port 64. The water pipe 69 is squeezed into the nozzle 610, and cooling water is sprayed from multiple nozzles 610 to the stamping parts to cool the stamping parts to prevent the stamping parts from overheating and damage during grinding. The flushed cooling water returns to the inner cavity 61 from the drain port 62 for reuse. At the same time, the first clamping plate 56 drives the second telescopic rod 74 to support the magnetic plate 72 upward when sliding, so that the magnetic plate 72 rises to the upper side of the first clamping plate 56. The debris generated by the stamping parts when being ground is flushed to the surface of the magnetic plate 72 under the flushing of the water flow, thereby adsorbing the debris.
