Description

Technical Field

[0001] The utility model belongs to the technical field of precious metal ultra-thin material processing, and in particular relates to a feeding auxiliary device for an ultra-thin precious metal alloy strip stamping device. Background Art

[0002] During the processing of ultra-thin precious metal alloy strips, the corrected ultra-thin precious metal alloy strips are sequentially discharged from the discharge port of the straightening machine, and then enter the stamping device (such as a punch press) through the feed port to obtain the required stamping parts. The remaining strip material after stamping (still in strip shape) is wound by the coiling mechanism on the discharge port side of the stamping device; ideally, the stepping speed of the straightening machine and the stamping device is consistent, and the strip between the straightening machine and the stamping device moves in a straight or substantially straight state, so that the strip can be horizontally moved to the mold surface of the stamping device; however, in actual production, the correction cannot be guaranteed. The stepping speed of the straightening machine and the punching device is exactly the same. Once the stepping speed of the punching device is greater than that of the straightening machine, the strip will be pulled or even broken. For this reason, a section of strip is usually reserved between the straightening machine and the punching device. The two ends of this section of strip are respectively placed on the rollers at the discharge end of the straightening machine and the feed end of the punching device, and the middle part is loose and drooping. Although such treatment can ensure the safety of the strip, there are still the following defects: First, the strip is not restricted when sliding on the surface of the roller, and the punching force will be transmitted toward the direction of the roller, which makes the moving direction of the strip difficult to control, and at least water The flat swing may cause deviation, and even cause the strip to bend or deform. Usually, a dedicated person is required to supervise and adjust the strip position at any time. In serious cases, the machine needs to be stopped for adjustment, resulting in reduced stamping efficiency and product quality. Secondly, the roller at the feed end of the stamping device is usually fixed. If the height of the stamping die is inconsistent during stamping of different batches, the upper end surface of the roller and the upper surface of the stamping die cannot be adjusted to be flush, which will inevitably affect the strip entry angle and even cause hard friction between the lower surface of the strip and the stamping die. Even if the upper end surface of the roller and the upper surface of the stamping die can be leveled, due to the difference between the roller and the upper surface of the stamping die, the strip will not be flush with the stamping die. There is a certain distance between the stamping dies, and the strip is unrestricted when sliding on the surface of the roller. The strip between the roller and the stamping die is also in a bent and drooping state. When feeding, hard friction is prone to occur between the lower surface of the strip and the edge of the die, which in turn causes surface scratches and reduces processing accuracy; thirdly, the straightening machine may also experience abnormal acceleration of discharge during the production process. Since the strip has a certain rigidity and is unrestricted when sliding on the surface of the roller, the strip will enter the stamping device at a speed exceeding the normal stamping rhythm, affecting the normal stamping operation and easily causing the strip to bend, fold, and other abnormal conditions.

[0003] To this end, a feeding auxiliary device suitable for ultra-thin precious metal alloy strip stamping equipment is designed to overcome the defects of roller-assisted feeding in the existing technology, which is very important for improving the processing efficiency and product quality of ultra-thin precious metal alloy strips.

[0008] 1. The utility model replaces the roller provided at the feed port of the stamping device with a supporting platen bent into an inverted L shape. By relatively arranging the horizontal plate and the pressure plate in the supporting platen and cooperating with the flexible pad material belt I and the flexible pad material belt II, the strip is horizontally moved in a channel with flexible materials on both sides. By selecting an appropriate distance between the pressure plate and the horizontal plate, the flexible material is used to avoid scratches on the surface of the strip. At the same time, the clamping force formed on both sides of the strip makes the strip between the supporting platen and the stamping die close to a taut state.

The utility model sets the pressure plate as a combination of a straight plate and an inclined plate connected by a transition arc, and the inclined plate is inclined upward toward the feed side; when the discharge from the straightening machine side is abnormally accelerated, even if the increased thrust causes the strip with a certain rigidity to jump upward significantly, the strip is pressed downward by the inclined plate and rebounds, which will not cause the strip to bend excessively or form creases, and the strip and the bottom surface of the inclined plate are in flexible contact, which will not cause damage to the strip surface.

[0011] 4. The two setting methods adopted by the utility model enable the supporting table to be raised and lowered through the sliding groove and the adjusting screw, so that the surface height of the horizontal plate can be adjusted according to the height of the stamping die to make the two flush.

The through holes on both sides of the straight plate 21 are slidably connected with the locking screws 1, and a locking nut is provided at the end of the locking screw 1. The free end of the inclined plate 22 faces the feed side and is inclined upward; the clamp 13 arranged on the upper surface of the inclined plate 22 clamps one end of the flexible pad material strip I23, and the other end of the flexible pad material strip I23 is arranged around the end and lower surface of the inclined plate 22 and the lower surface of the straight plate 21 and extends from the free end of the straight plate 21; the clamp 13 arranged on the bottom surface of the horizontal plate 32 on the feed side clamps one end of the flexible pad material strip II34, and the other end of the flexible pad material strip II34 is arranged around the end and upper surface of the horizontal plate 32 and extends to the side of the upper end of the vertical plate 31; the feeding channel for the ultra-thin precious metal alloy strip is between the flexible pad material strip I23 and the flexible pad material strip II34.

[0018] In the above technical solution, the vertical plate 31 of the supporting plate is directly fixed to the side of the feed port of the punching device through the sliding groove 14 and the adjusting screw 7. The height of the horizontal plate 32 can be adjusted by moving the vertical plate 31.

[0019] Combined with attachment Figure 1 、 2It can be seen that, as a preferred embodiment, the present invention further includes a mounting seat 8 and a slide plate 9 of adapted size; the mounting seat 8 is a thick rectangular plate, one side plane of the mounting seat 8 is fixedly arranged on the side of the feed port of the punching device, and the adjusting screw 7 is vertically arranged on the other side plane of the mounting seat 8; the back side of the vertical plate 31 is fitted with the slide plate 9 and combined into one by the fixing screw 5, a vertical sliding groove 14 is set through the vertical plate 31 and the slide plate 9 and slides with the adjusting screw 7, and the slide plate 9 and the adjusting screw 7 are locked by the locking nut at the end of the adjusting screw 7.

[0020] The above technical solution further optimizes the setting method of the supporting table, and one side of the mounting seat 8 is fixedly set on the side of the feed port of the stamping device. The vertical plate 31 is slid and lifted with the help of the slide plate 9, lifting screw 10 and other structures, which is more convenient for adjustment.

[0021] A spring 6 is arranged between the locking nut of the locking screw 1 and the flat plate 21; a spring 6 of appropriate hardness is selected, and combined with the flexible pad material strip I23 and the flexible pad material strip II34, a flexible feeding channel with a certain elasticity is provided for the ultra-thin precious metal alloy strip, which facilitates the adjustment of the clamping force on both sides of the strip.

[0022] The free end of the flat plate 21 is an upwardly curled arc structure to avoid damage to the surface of the ultra-thin precious metal alloy strip.

[0023] The angle between the inclined plate 22 and the horizontal plate 32 is 10-20 degrees.

[0024] The end of the horizontal plate 32 is provided with an extension section 33 downward through a transition arc, and the angle between the extension section 33 and the horizontal plate 32 is 45~90°. A clamp 13 is provided on the back side of the extension section 33, and the flexible pad material II34 clamped by the clamp 13 is arranged around the end and surface of the extension section 33 and the upper surface of the horizontal plate 32 and extends to the side of the upper end of the vertical plate 31; with such a setting, the side of the extension section 33 supports the lower surface of the ultra-thin precious metal alloy strip, avoiding the adverse effect of the end of the horizontal plate 32 on the surface of the strip; setting the angle between the extension section 33 and the horizontal plate 32 to 45~90° can ensure that the extension section 33 will not damage the surface when the strip moves vertically.

[0026] The sliding grooves 14 are symmetrically arranged in two groups, and the two groups of sliding grooves 14 are slidably matched with the two adjusting screws 7. An oblique support 4 is set between the vertical plate 31 and the horizontal plate 32. With such an arrangement, the combined structure is more stable and has higher structural strength.

[0027] A rotating handle 12 is provided at the lower end of the lifting screw 10 .

[0028] The supporting plate, the pressing plate, the mounting seat 8 and the sliding plate 9 are made of stainless steel and have a polished surface.

[0029] The fixing screws 5 are symmetrically arranged in two pieces, and washers cooperating therewith are arranged on the fixing screws 5 and the adjusting screw 7; with such an arrangement, the assembled structure is more stable.

[0030] The working principle of this utility model:

[0031] Compared with the prior art, the present invention replaces the roller provided at the feed port of the punching device with a supporting plate bent into an inverted L shape. The horizontal plate 32 in the supporting plate provides a plane for guiding the horizontal movement of the strip. At the same time, the pressure plate arranged opposite to the horizontal plate 32 restricts the upward movement of the strip, and cooperates with the flexible pad belt I23 and the flexible pad belt II34 to enable the strip to move horizontally in the channel where the flexible material is adhered on both sides. When the distance between the pressure plate and the horizontal plate 32 is set appropriately (mainly to adapt to strips of different thicknesses), the flexible material can avoid scratches on the surface of the strip. When the strip is fed, a certain clamping force is formed on both sides of the strip; because the strip has a certain rigidity and has been corrected, and the continuous force of the winding mechanism at the discharge end of the stamping device is applied, even if the strip between the supporting platen and the straightener is still in a relaxed and drooping state, the clamping force during feeding not only limits the deviation of the strip, but also makes the strip between the supporting platen and the stamping die close to a taut state; even if the stepping speed of the stamping device is abnormally accelerated, the clamping force is not enough to limit the movement of the strip, and the strip will not be damaged, which overcomes the defects of the roller-assisted feeding in the prior art.

[0032] In addition, the flexible pad material strip II34 extends to the side of the upper end of the vertical plate 31. Since the flexible pad material strip II34 has a certain thickness, when the surface of the horizontal plate 32 is flush with the surface of the stamping die, the position of the strip at the end of the supporting plate is slightly higher than the surface of the stamping die; in this case, even if the strip between the supporting plate and the stamping die is slightly loose, the lower surface of the strip will not cause hard friction with the edge of the stamping die.

[0033] Furthermore, the pressure plate is set to be a combination of a straight plate 21 and an inclined plate 22 connected by a transition arc. The straight plate 21 cooperates with the horizontal plate 32 to control the horizontal movement of the strip, and the inclined plate 22 tilts upward toward the feed side; when the discharge from the straightening machine side is abnormally accelerated, the increased thrust causes the strip with a certain rigidity to form a large jump upward. If the end of the pressure plate is in a flat state, the large jump may cause the strip to bend or form a crease at the edge of the pressure plate; relatively speaking, due to the provision of the inclined plate 22, the strip with a large jump tendency is pressed and rebounded by the bottom surface of the inclined plate 22, and is not prone to excessive bending or crease formation. Moreover, the strip is in surface contact with the bottom surface of the inclined plate 22, and the presence of the flexible pad belt I23 will not cause damage to the strip surface.

[0034] In addition, the present invention adopts two ways to set the supporting table. No matter which way, the surface of the horizontal plate 32 and the surface of the stamping die can be adjusted to be flush with each other through the sliding groove 14 and the adjusting screw 7, overcoming the defects of the prior art when using rollers to assist feeding.

[0035] Application method of the utility model:

[0036] The vertical plate 31 is set on the side of the feed port of the stamping device through the sliding groove 14, the adjusting screw 7 directly or through the mounting seat 8 and the associated lifting structure, and the surface of the horizontal plate 32 is adjusted to be flush with the surface of the stamping die; then, the flexible mat material strip II34 is clamped by the clamp 13 of the horizontal plate 32 and arranged in a circle until it extends to the side of the upper end of the vertical plate 31. The flexible mat material strip II34 is located between the two locking screws 1. The spacing between the two locking screws 1 is adapted to the width of the strip. Usually, a larger spacing is selected to accommodate strips of more width specifications; the flexible mat material strip I23 is clamped by the clamp 13 of the inclined plate 22 and arranged in a circle (it will eventually Extend the free end of the straight plate 21), then sleeve the straight plate 21 on the locking screw 1, arrange the flexible mat material belt I23 between the two locking screws 1 and fit it up and down with the flexible mat material belt II34; introduce the end of the belt between the flexible mat material belt I23 and the flexible mat material belt II34, and control the distance between the pressure plate and the horizontal plate 32 according to the thickness of the belt, so that a suitable clamping force is formed through the flexible mat material belt and the belt can move with the driving force, and then tighten the locking nut on the locking screw 1; reserve a certain length of belt between the supporting table and the discharge end of the straightening machine, and keep it in a relaxed drooping state; then start the straightening machine and the punching device to perform the straightening and punching operations.

[0037] Example 1: The ultra-thin precious metal alloy to be stamped is AgCu alloy, which is a strip material with a thickness of 0.4 mm and a width of 15 mm; during the assembly process of the present invention, the flexible mat material strip I23 and the flexible mat material strip II34 are both made of dust-free, clean, thickened medical absorbent cotton gauze, and the strip is introduced between the flexible mat material strip I23 and the flexible mat material strip II34. The distance between the pressing plate and the horizontal plate 32 is adjusted according to the thickness of the strip and locked (for the strip that has been corrected, the locking screw 1 can be tightened slightly to ensure that the strip can move normally, so that a better clamping force can be formed); the utility model can make the ultra-thin AgCu alloy strip smoothly fed, the stamping process proceeds smoothly, there is no bending, deformation and offset of the strip, and the surface of the product after processing is clean and tidy.

[0038] Example 2: The ultra-thin precious metal alloy to be stamped is AgCuGa alloy, AgCuPd alloy, AgCuIn alloy, etc. The operation is carried out according to Example 1. The feeding is also stable and the stamping process is smooth. There is no bending, deformation or offset of the strip. The surface of the product after processing is clean and tidy.

[0039] Comparative example: The strip is the same as that in Example 1. Due to the use of traditional roller-assisted feeding, the strip swings left and right during the feeding process; when the step speed of the stamping device is accelerated, the strip falls off the roller, causing serious distortion of the strip during stamping. The machine is then stopped and calibrated again, but the previous situation occurs many times, and oil and dust remain on the product after processing; relatively speaking, the production efficiency of Examples 1 and 2 is more than three times that of the comparative example, and the product quality is good.
