DETAILED DESCRIPTION

[0031] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific embodiments.

[0032] Among them, the drawings are only used for illustrative explanations, and they only represent schematic diagrams rather than actual pictures, and should not be understood as limitations on the present application; in order to better illustrate the embodiments of the present invention, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.

[0033] Embodiment 1: This embodiment provides a stainless steel standard part stamping device, specifically as follows Figure 1-Figure 5As shown, it includes a workbench 1, and the workbench 1 includes a frame 101. A stamping assembly 2 is arranged on the frame 101. The stamping assembly 2 includes two symmetrically arranged stamping die units and an adjusting slide 205 for installing the stamping die units. The adjusting slide 205 is slidably connected to the frame 101. The stamping assembly 2 also includes a hydraulic cylinder 201 installed on the frame 101, and an outer edge punching head 203 is installed on the hydraulic cylinder 201; the adjusting slide 205 is slidably connected to the adjusting frame 202, and the adjusting frame 202 is connected to the frame 101 through a reset spring 204. The longitudinal movement of the adjusting frame 202 drives the two adjusting slides 205 to move horizontally and in opposite directions, and the outer edge punching head 203 is engaged with the adjusting frame 202; when the two stamping die units are fitted together, they are spliced ​​into a stamping die set, and the outer edge punching head 203 cooperates with the stamping die set to stamp the stainless steel plate 5.

[0034] When the hydraulic cylinder 201 extends out to push the outer edge punch head 203, the outer edge punch head 203 is embedded in the adjusting frame 202, and then drives the adjusting frame 202 to move synchronously, the return spring 204 is compressed, and the downward pressure of the adjusting frame 202 causes the two adjusting slides 205 to move horizontally and approach each other, that is, the two stamping die units approach each other. When the two stamping die units are fitted, the adjusting frame 202 continues to press down, but at this time the adjusting slide 205 will only be limited by the adjusting frame 202 and will not continue to move. As the adjusting frame 202 is pressed down, the outer edge punch head 203 begins to press the stainless steel plate 5 on the stamping die group against the stamping die group for stamping. After the stamping is completed, the hydraulic cylinder 201 retracts, and the adjusting frame 202 moves upward and resets under the elastic force of the return spring 204. When the adjusting frame 202 is reset, the stamping die unit is also separated. At this time, the standard parts on the stamping die unit after stamping begin to fall onto the frame 101 due to the separation of the two stamping die units. Through the above arrangement, after stamping the stainless steel plate 5, the two stamping die units of the stamping die set can be separated to quickly remove the stamped standard parts from the stamping die set. The standard parts will not be stuck in the stamping die set, and manual removal is unnecessary, thereby improving work efficiency.

[0035] Embodiment 2: This embodiment is further expanded on the basis of Embodiment 1, specifically as follows Figure 4-Figure 9As shown, the stamping die unit includes a stamping die seat 206, which is slidably connected to the adjusting slide 205, and the adjusting slide 205 is provided with a mounting pin 210, which is inserted into the stamping die seat 206 to fix it on the adjusting slide 205; a stamping pad 216 and a sliding ring 218 are slidably connected to the stamping die seat 206, and a first limiting ring 219 is provided between the stamping pad 216 and the stamping die seat 206, and an inner edge stamping head 214 is installed on the stamping die seat 206, and at least two screws 222 are provided on the inner edge stamping head 214, and the inner edge stamping head 214 is fixed to the stamping die seat 206 by the cooperation of a nut 217 and the screw 222. On the die seat 206; the stamping die unit also includes a separation ring 215, a second limit ring 220 is arranged between the separation ring 215 and the sliding ring 218, the inner edge of the stamping pad 216 is in contact with the outer edge of the separation ring 215, the inner edge of the separation ring 215 is in contact with the outer edge of the inner edge punching head 214, and a stamping spring 221 is arranged between the separation ring 215 and the stamping die seat 206; a through hole is arranged on the outer edge punching head 203, and the shape of the through hole is the same as the outer edges of the two spliced ​​inner edge punching heads 214; the outer edge punching head 203 cooperates with the two stamping pads 216 to perform a primary stamping, and the two inner edge punching heads 214 cooperate with the outer edge punching head 203 to perform a secondary stamping.

[0036] The specific models and shapes of the inner edge punch head 214, separation ring 215, punch pad 216 and outer edge punch head 203 in the punch die unit can be selected according to the style of the specific standard parts to be processed. By replacing the punch die unit, a variety of standard parts can be stamped, which is more practical.

[0037] When the outer edge punch head 203 is pressed down to the stainless steel plate 5, the outer edge punch head 203 cooperates with the punch pad 216 to punch out the steel plate, and then the outer edge punch head 203 continues to press down, and the punched standard blank is pressed on the separation ring 215, and the punch spring 221 begins to be compressed until the standard blank contacts the inner edge punch head 214. At this time, the inner edge punch head 214 cooperates with the outer edge punch head 203 to further punch out the standard blank to obtain a standard finished product, and the waste punched from the standard blank stays on the inner edge punch head 214; then the outer edge punch head 203 moves upward to reset, and the separation ring 215 is also reset under the action of the punch spring 221. By setting the inner edge punch head 214, the annular standard part can be punched once, reducing the punching process and improving the working efficiency.

[0038] like Figure 5 As shown, an anti-blocking rod 208 is slidably connected in the through hole on the outer edge punching head 203 , and an anti-blocking spring 209 is arranged between the anti-blocking rod 208 and the outer edge punching head 203 .

[0039] When the inner edge punch head 214 cooperates with the outer edge punch head 203 to perform secondary punching on the standard part blank, the waste from the secondary punching may remain in the through hole on the outer edge punch head 203. When the outer edge punch head 203 is reset, the anti-blocking rod 208 is no longer squeezed by the inner edge punch head 214, so it begins to reset under the action of the anti-blocking spring 209. At this time, the anti-blocking rod 208 can push the waste from the secondary punching out of the through hole on the outer edge punch head 203, and place the waste in the through hole.

[0040] like Fig. 9 As shown, when the stamping spring 221 is not under pressure, the height difference between the separation ring 215 and the stamping pad 216 is a, the height difference between the inner edge stamping head 214 and the separation ring 215 is also a, and the thickness of the stainless steel plate 5 is less than a.

[0041] Since the height difference a is provided, after the outer edge punch head 203 is reset, the punch spring 221 drives the separation ring 215 to reset. When the separation ring 215 completes the reset, the punched standard parts will stay at the height difference between the separation ring 215 and the punch pad 216, and the secondary punched waste will stop at the height difference between the separation ring 215 and the inner edge punch head 214. This setting can prevent the standard parts from being pushed back onto the steel plate and the secondary punching waste from being pushed back onto the standard parts, so that the standard parts are separated from the stainless steel plate 5, and the secondary punching waste is separated from the standard parts, without the need for subsequent further processing, thereby improving the operating efficiency.

[0042] like Figure 4 , Figure 6 As shown, the stamping die unit also includes a correction unit for correcting the position of the stainless steel plate 5, and the correction unit includes a pulley seat 213 slidably connected to the stamping die seat 206, a correction spring 211 is arranged between the pulley seat 213 and the stamping die seat 206, and a pulley 212 is arranged on the pulley seat 213.

[0043] By correcting the stainless steel plate 5 through two sets of correction units, it is possible to effectively prevent the stainless steel plate 5 from being offset at the stamping position, which results in an incomplete stamping standard part, and effectively reduce the scrap rate.

[0044] like Figure 5 , Fig.10As shown, the frame 101 is also provided with a lubrication assembly 3, and the lubrication assembly 3 includes a rotating drum 302 rotatably connected to the frame 101, a return torsion spring 305 is provided between the rotating drum 302 and the frame 101, the rotating drum 302 is fixedly connected to a steering column 303 and an oil collecting box 301, and the oil collecting box 301 is provided with an oil spray lubrication unit, where the oil spray lubrication unit is a common device adaptively selected by technicians in this field, the lubrication assembly 3 also includes a pressure rod 304 fixedly connected to the output end of the hydraulic cylinder 201, and the pressure rod 304 cooperates with the steering column 303; the outer edge punch head 203 is obliquely provided with a lubrication oil channel 207 with a connecting through hole.

[0045] When the hydraulic cylinder 201 is extended, the pressure rod 304 squeezes the steering column 303 to make the rotating drum 302 rotate, and the return torsion spring 305 is squeezed. After the rotating drum 302 rotates, the oil collecting box 301 will not interfere with the displacement of the outer edge punching head 203. Then the pressure rod 304 continues to move downward, but it only limits the steering column 303; when the hydraulic cylinder 201 is retracted, the pressure rod 304 moves synchronously. When the height of the outer edge punching head 203 is slightly higher than the opening on the oil collecting box 301, the inclined surface of the pressure rod 304 begins to contact the steering column 303. At this time, the steering column 303 begins to reverse and reset under the action of the return torsion spring 305. When the oil collecting box 301 moves to the position directly below the outer edge punching head 203, the oil injection lubrication unit on the oil collecting box 301 starts to spray oil on the outer edge punching head 203, and the excess oil on the outer edge punching head 203 drips into the oil collecting box 301. Some of the oil will flow into the lubricating oil passage 207. Since the anti-blocking rod 208 blocks the hole at one end of the lubricating oil passage 207, the oil is temporarily stored in the lubricating oil passage 207. When the inner edge punching head 214 performs secondary punching, the anti-blocking rod 208 moves to cause the oil in the lubricating oil passage 207 to flow to the inner edge punching head 214, thereby lubricating the inner edge punching head 214. With this arrangement, the punching part can be continuously lubricated to prevent abnormal operation due to lack of lubricating oil in the punching part.

[0046] like Fig.11 As shown, a first filter plate 106 is installed on the frame 101, and a second filter plate 105 is installed on the first filter plate 106. A standard parts collection box 102 is provided at the discharge end of the first filter plate 106, a waste collection box 103 is provided at the discharge end of the second filter plate 105, and a debris collection box 104 is provided at the leakage end of the second filter plate 105.

[0047] The frame 101 is provided with a leak hole. When the two stamping die units are separated, the standard parts, secondary stamping waste and some debris will fall on the first filter plate 106 through the leak hole. At this time, the standard parts fall into the standard parts collection box 102 along the first filter plate 106, and the secondary stamping waste and debris fall on the second filter plate 105 through the holes on the first filter plate 106. At this time, the secondary stamping waste falls into the waste collection box 103 along the second filter plate 105, and the debris falls into the debris collection box 104 through the holes on the second filter plate 105. Through the above arrangement, the standard parts, secondary stamping waste and debris can be separated and then collected, thereby improving the working efficiency.

[0048] like Fig.12 As shown, a conveying assembly 4 is also provided on the frame 101, and the conveying assembly 4 includes two groups of transmission units, one group of transmission units is responsible for feeding, and the other group of transmission units is responsible for discharging; the transmission unit includes two conveying rollers 401, and a gear 403 is fixedly connected to the conveying roller 401, and the two gears 403 are meshed. The conveying roller 401 is rotatably connected to the frame 101, and a motor 402 is installed on the frame 101. One conveying roller 401 is transmission-connected to the motor 402, and a stainless steel plate 5 is placed between the two conveying rollers 401.

[0049] The motor 402 is started intermittently. When the motor 402 is started, the two conveying rollers 401 drive the stainless steel plate 5 to move a certain distance. When the stainless steel plate 5 moves to the stamping position, the motor 402 stops. After the stamping of the stainless steel plate 5 is completed, the motor 402 continues to start, so that the stainless steel plate 5 continues to move a certain distance. This is repeated until the stainless steel plate 5 is completely used up. Through the above arrangement, there is no need for personnel to transport, which reduces the labor intensity of personnel on the one hand, and on the other hand, the distance of the stainless steel plate 5 when it moves is more uniform and accurate, which can greatly improve the utilization rate of the stainless steel plate 5.

[0050] Example 3: This example is described on the basis of Example 2, taking the stamped standard part as a bolt washer as an example. In this example, the inner edge of the stamped pad 216 is a semicircular arc, the inner and outer edges of the separation ring 215 are both semicircular arcs, the outer edge of the inner edge punching head 214 is a semicircular arc, the outer edge of the outer edge punching head 203 is a circular arc, and the through hole on the outer edge punching head 203 is circular in shape.

[0051] During operation, the conveying assembly 4 is first started, and the stainless steel plate 5 is conveyed for a distance by the conveying assembly 4, so that the stainless steel plate 5 is in the stamping position, and then the stainless steel plate 5 stops moving. At this time, the oil injection lubrication unit on the lubrication assembly 3 sprays lubricating oil on the outer edge stamping head 203, and then the hydraulic cylinder 201 is started. Driven by the hydraulic cylinder 201, the outer edge stamping head 203 moves downward, and the inclined surface of the pressure rod 304 begins to squeeze the steering column 303, so that the rotating drum 302 rotates, and the oil collecting box 301 is away from the outer edge stamping head 203, and then the outer edge stamping head 203 is embedded in the adjustment frame 202. In the process, the adjusting frame 202 is driven to move synchronously. When the adjusting frame 202 moves, the reset spring 204 is compressed. At the same time, driven by the adjusting frame 202, the two adjusting slides 205 begin to drive the extrusion die units to approach each other. When the extrusion die units are fitted, the adjusting frame 202 continues to descend, the adjusting slide 205 stops moving, and the outer edge punching head 203 begins to punch the stainless steel plate 5 for the first time. This time, the outer edge of the bolt washer is punched out to form a bolt washer blank. After that, the outer edge punching head 203 presses the bolt washer blank onto the separation ring 215. The separation ring 215 is pressed down, and the punching spring 221 is compressed, and then the bolt washer blank contacts the inner edge punch head 214. At this time, as the outer edge punch head 203 continues to press down, the inner edge punch head 214 begins to perform secondary punching on the bolt washer blank, and the inner edge of the bolt washer is punched out here to form a complete bolt washer; then the hydraulic cylinder 201 drives the outer edge punch head 203 to start resetting, and the anti-blocking rod 208 pushes out the secondary punching waste under the action of the anti-blocking spring 209, and the separation ring 215 is reset under the action of the punching spring 221, and the stainless steel plate 5, the bolt washer and the secondary punching waste stay at different heights in the punching die set. position, realizing the separation of the bolt washer from the stainless steel plate 5 and the secondary stamping waste respectively; with the reset of the outer edge punch head 203, the two adjusting slides 205 drive the stamping die unit to separate, and the bolt washer and the secondary stamping waste begin to fall on the first filter plate 106, and are finally collected respectively; with the reset of the outer edge punch head 203, the pressure rod 304 no longer limits the steering column 303, and the rotating drum 302 rotates and resets to the bottom of the outer edge punch head 203 under the action of the reset torsion spring 305. At this time, the oil injection lubrication unit once again sprays lubricating oil on the outer edge punch head 203, and this cycle can be carried out.

[0052] The present invention is not limited to the above-mentioned specific implementation modes. Various changes made by technicians in the relevant technical field based on the above-mentioned conception without creative work all fall within the protection scope of the present invention.
