Description

Technical Field

[0001] This utility model belongs to the field of continuous stamping, and specifically relates to an automatic continuous stamping device. Background Technology

[0002] In the field of stamping machines, although existing automatic stamping devices have initially achieved automation of stamping and forming of strips, there are still many technical defects in the design of the perforation area, especially in the multi-process continuous processing flow, making it difficult to balance production efficiency and processing accuracy.

[0003] Existing perforation mechanisms lack precise depth limiting and positioning structures. On the one hand, the perforation depth largely relies on manual preset mechanical stroke, which cannot be dynamically adjusted according to the actual thickness of the sheet metal flange. This can easily lead to problems such as excessively deep holes causing flange damage or excessively shallow holes failing to meet subsequent installation requirements. On the other hand, perforation is only positioned by a single guide component, and there is no targeted clamping structure in the sheet metal flange area. During the stamping and perforation process, the flange is prone to warping or displacement due to stress, causing the hole position to deviate from the design reference, resulting in a low product qualification rate. Furthermore, the perforation process is often designed independently from the preceding stamping and straightening processes. The stamped and straightened sheets need to be transferred to a dedicated perforation station or equipment for processing, which not only increases the sheet metal transfer time and causes production interruptions, but also affects the overall assembly accuracy of the product due to positioning errors during multiple transfers. Utility Model Content

[0045] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0046] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0047] This utility model provides an automatic continuous stamping device for forming several products on a strip of material, comprising: a fixed die base 2 and a movable die base 1. The fixed die base 2 guides the strip of material 3 from an external feeder into its interior; the movable die base 1 is movably disposed above the fixed die base 2; a cutting area 10 is disposed on the movable die base 1, and the cutting area 10 is used to form two symmetrically arranged and interconnected sheet pieces 30 on the strip of material 3; and a stamping area 11 is disposed on the movable die base 1, and the stamping area 11 is used to stamp along a line perpendicular to the two sheet pieces 30. The stamping is performed along the symmetry line to form the main body 300 and the connecting part 301 on the two sheets 30. The stamping is also performed along a direction parallel to the symmetry line of the two sheets 30 to form a convex part 300a and a concave part 301a on the sidewalls of the main body 300 and the connecting part 301, respectively. The ends of both concave parts 301a are formed with flanges 302 perpendicular to the connecting part 301. The straightening area 12 is used to press and fold the flanges 302 along the bottom of the fixed mold base 2, so that the flanges 302 and the connecting part... The side walls of the connecting part 301 are on the same vertical plane; the perforated area 13 includes a pressing block 130 and a pushing block 133. The pressing block 130 is disposed on the moving mold base 1 and is connected to a positioning plate 131. The pushing block 133 is movably disposed on both sides of the two material pieces 30. The pushing block 133 is provided with a positioning groove 134 and a perforating head 136a. The positioning groove 134 includes a guide surface 134a and a locking surface 134b. The pressing block 130 moves against the pushing block 133. When the positioning... When plate 131 is located on guide surface 134a, pressing block 130 and positioning plate 131 push pushing block 133 to move along flange 302 direction, and when positioning plate 131 abuts against locking surface 134b, perforating head 136a forms hole on flange 302 and is used to limit the depth of perforating head 136a forming hole on flange 302; demolding area 14 is provided on moving mold base 1, demolding area 14 is used to cut the connection between two formed material pieces 30 to form independent products.

[0048] like Figures 1 to 6As shown, the external feeder transports the strip 3 to the interior of the fixed mold base 2. The movable mold base 1, which is movably mounted above the fixed mold base 2, begins to perform a stamping action (i.e., repeatedly moving closer to and away from the fixed mold base). The cutting area 10 first forms two symmetrical and connected pieces 30 on the strip 3. The stamping area 11 stamps out the main body 300 and the connecting part 301 along a direction perpendicular to the symmetry line of the pieces 30, and then stamps along a direction parallel to the symmetry line of the pieces 30, so that the side wall of the main body 300 forms a convex part 300a and the side wall of the connecting part 301 forms a concave part 301a, and the end of the concave part 301a forms a flange 302 perpendicular to the connecting part 301. The straightening area 12 moves the flange 302 along the fixed mold base. The bottom of seat 2 is squeezed and folded so that the flange 302 and the side wall of the connecting part 301 are on the same vertical plane. In the perforation area 13, the pressing block 130 and the positioning plate 131 simultaneously push the pushing block 133, so that the pushing block 133 moves and presses against the flange 302. At the same time, the positioning plate 131 slides along the guide surface 134a to the locking surface 134b and presses against the locking surface 134b, perforating the flange 302 and limiting the perforation depth. Finally, the demolding area 14 cuts the connection between the two material pieces 30 to obtain the product, realizing the full-process automation from material strip 3 to independent product, greatly reducing manual intervention, improving production efficiency, and ensuring product accuracy and improving product quality through the perforation area 13.

[0049] A first buffer spring is provided on the fixed mold base 2, and a connecting hole is provided on the material strip 3. The first buffer spring is movably connected to the connecting hole and is used to support the material strip 3 so that the feeder can send the material strip 3 to the next processing area.

[0050] When the moving mold base 1 presses downward, the first buffer spring (not shown in the figure) at the bottom of the strip 3 is compressed downward. After the moving mold base 1 is completed, it is lifted upward. The first buffer spring is elastically reset and lifts the strip 3. Then the feeder sends the strip 3 to the next processing area. The first buffer spring is set at the connection of the two strips 30 to facilitate the transmission of the strip 3 on the fixed mold base 2 and prevent the strip 3 from interfering with other parts on the fixed mold base 2. This can effectively reduce the wear of parts and improve work efficiency.

[0051] One end of the positioning plate 131 is fixedly connected to the pressing block 130 along an inclined direction perpendicular to the positioning groove 134. The other end of the positioning plate 131 is provided with a slider 132. The slider 132 is provided with a first sliding surface 132a and a second sliding surface 132b. When the first sliding surface 132a is located on the guide surface 134a, the pressing block 130 and the positioning plate 131 push the pushing block 133 to move along the flange 302. When the second sliding surface 132b is located on the locking surface 134b, the depth of the hole formed by the perforating head 136a on the flange 302 is limited.

[0052] like Figure 3 As shown, Figure 3The positioning grooves 134 are symmetrically arranged on both sides of the push block 133. When the moving mold base 1 is stamping, the pressing block 130 drives the positioning plate 131 to move downward. The positioning plate 131 slides in the positioning groove 134. The first sliding surface 132a on the slider 132 slides to the guide surface 134a. At this time, the pressing block 130 and the positioning plate 131 simultaneously push the push block 133 to move along the flange 302. As the pressing block 130 continues to move downward, the second sliding surface 132b of the slider 132 slides to the locking surface 134b. The locking surface 134b restricts the positioning plate 131 from continuing to move, thereby accurately controlling the perforation depth of the perforation head 136a on the flange 302 on the push block 133 and improving product quality.

[0053] The push block 133 is provided with a guide slope 135 perpendicular to the tilt direction of the positioning groove 134. The guide slope 135 is connected to the positioning groove 134. One end of the guide slope 135 is connected to the end of the locking surface 134b. The guide slope 135 is used to reduce the row distance between the pressing block 130 and the push block 133.

[0054] like Figure 3 As shown, when the pressing block 130 completes the perforation action and disengages from the pushing block 133, the positioning plate 131 moves upward with the pressing block 130. By setting the guide slope 135, the positioning plate 131 does not need to slide completely out of the positioning groove 134. It only needs to disengage from the locking surface 134b to quickly disengage from the pushing block 133. This reduces the distance required for the pressing block 130 to disengage from the pushing block 133, prevents the positioning plate 131 from jamming with the positioning groove 134, and saves materials and reduces manufacturing costs by setting the guide slope 135.

[0055] The pressing block 130 is provided with a first pressing inclined surface, and the pushing block 133 is provided with a second pressing inclined surface. The first pressing inclined surface is used to move and press against the second pressing inclined surface, so that the first pressing surface and the slider 132 simultaneously push the pushing block 133 to move and press against the flange 302.

[0056] During stamping, the first stamping inclined surface and the second stamping inclined surface move and abut against each other. At the same time, the slider 132 cooperates with the positioning groove 134, so that the first stamping inclined surface and the slider 132 simultaneously push the push block 133 to move and abut against the flange 302, providing a stable positioning base for the piercing head 136a to pierce on the flange 302 and ensuring accurate piercing position.

[0057] The push block 133 includes: a mounting plate 136, which is fixedly connected to the push block 133; an extrusion plate 137, one end of which movably abuts against two material pieces 30, and the other end of which movably abuts against the mounting plate 136; a through-hole head 136a is provided on the mounting plate 136 and passes through the extrusion plate 137; and a compression spring 138, one end of which is connected to the push block 133, and the other end passes through the mounting plate 136 and is connected to the extrusion plate 137.

[0058] like Figure 4 As shown, when the push block 133 moves to press against the flange 302, it pushes the mounting plate 136 and the extrusion plate 137 to move towards the two pieces 30, so that the extrusion plate 137 moves to press against the two pieces 30, and the piercing head 136a passes through the extrusion plate 137 to pierce the flange 302. After piercing, the pressing block 130 is lifted, and the compression spring 138 returns to its elastic state, pushing the block 133 to move away from the two pieces 30, preparing for the next processing. This achieves both stable fixing of the pieces 30 and ensures the accuracy of piercing.

[0059] The demolding area 14 includes: a support block 21, which is disposed on the fixed mold base 2, and the top wall of the support block 21 is movably abutting against two material sheets 30; a second buffer spring 20, one end of which is connected to the fixed mold base 2 and the other end of which is connected to the support block 21; a top head 141 and a support base 140, the support base 140 being fixedly connected to the moving mold base 1 through a connecting plate 144, a connecting rod 142 being disposed on the support base 140, the top head 141 being movably connected to the end of the connecting rod 142, an elastic element 143 being sleeved on the connecting rod 142, one end of the elastic element 143 being connected to the top head 141 and the other end being connected to the support base 140.

[0060] like Figure 6 As shown, when the two processed material pieces 30 are sent to the demolding area 14, the second buffer spring 20 lifts the support block 21, so that the connection between the two material pieces 30 abuts against the ejector head 141. Under the buffering effect of the elastic element 143, the ejector head 141 pushes against the connection between the two material pieces 30 to adjust the position of the two material pieces 30 relative to the fixed mold base 2. This is beneficial to improve product accuracy and increase work efficiency. Furthermore, by setting the elastic element 143, the thrust generated by the abutment against the ejector head 141 can be reduced, thus extending the service life of the parts.

[0061] It is worth mentioning that the stamping area 11 is provided with a bending die 110, which is used to form the main body 300 and the connecting part 301 on the two sheets 30.

[0062] The stamping area 11 is provided with a stamping block 111, and the stamping block 111 is provided with a curved groove 112. The sidewall of the curved groove 112 is formed with a concave arc 112a and a convex arc 112b that are connected to each other, so that a convex part 300a and a concave part 301a can be formed on the sidewall of the main body 300 and the connecting part 301 respectively.

[0063] like Figure 1 and Figure 5As shown, during stamping, the stamping block 111 first stamps the sheet 30 along a direction perpendicular to the symmetry line of the sheet 30 to form the main body 300 and the connecting part 301; then the stamping continues, the convex arc 112b of the curved groove 112 presses the side wall of the main body 300 to form the convex part 300a, and the concave arc 112a presses the side wall of the connecting part 301 to form the concave part 301a. The shape of the curved groove 112 is used to shape specific parts of the sheet 30.

[0064] The straightening area 12 includes: a first pressing block 120, which is used to press and fold the flange 302 along the bottom of the fixed mold base 2; an extrusion block 121, which is disposed on the fixed mold base 2, and the extrusion block 121 is provided with an arc surface 121a and an extrusion part 121b, the extrusion part 121b being used to movably press against the flange 302; and a second pressing block 122, which is disposed on the moving mold base 1, and the second pressing block 122 is provided with a pressing inclined surface 122a, the pressing inclined surface 122a being used to movably press against the extrusion block 121, so that the flange 302 and the side wall of the connecting part 301 are on the same vertical plane.

[0065] like Figure 1 and Figure 2 As shown, during stamping, the first pressure block 120 presses and folds the flange 302 along the bottom of the fixed mold base 2 and sends it to the next processing area for stamping again. The pressure inclined surface 122a of the second pressure block 122 is movably pressed against the extrusion block 121, and the extrusion part 121b on the extrusion block 121 is movably pressed against the flange 302, so that the flange 302 and the side wall of the connecting part 301 are on the same vertical plane, which is beneficial to improving product quality and ensuring processing accuracy.

[0066] The demolding area 14 includes: a cutter 145, which is disposed on the moving mold base 1. The cutter 145 is used to cut the connection between the two formed material pieces 30 to form an independent product; and a material distribution platform 22, which is disposed on the fixed mold base 2. The material distribution platform 22 is provided with a first discharge port 22a and a second discharge port 22b symmetrically distributed on both sides of the first discharge port 22a. The first discharge port 22a is used to receive waste material, and the second discharge port 22b is used to receive products.

[0067] When the moving mold base 1 presses downward, the cutter 145 cuts the connection between the two formed material pieces 30, so that the waste material slides out from the first discharge port 22a and the product slides out from the second discharge port 22b, which helps to improve work efficiency, can quickly complete sorting, and reduce labor costs.

[0068] The working principle of this automatic continuous stamping device is as follows:

[0069] The external feeder transports the strip 3 to the fixed mold base 2. After the fixed mold base 2 guides the strip 3 in, it first cuts the strip 3 through the cutting area 10 to form two symmetrically connected pieces 30. The stamping area 11 first stamps out the main body 300 and the connecting part 301 along the direction perpendicular to the symmetry line of the pieces 30. Then, the curved groove 112 stamps out the convex part 300a, the concave part 301a and the flange 302 along the direction parallel to the symmetry line of the pieces 30. The straightening area 12 initially folds the strip through the first pressure block 120. Flanging 302 is then pressed by the pressing inclined surface 122a of the second pressing block 122, pushing the extrusion block 121 to press the flange 302 to the same vertical surface as the side wall of the connecting part 301. In the perforated area 13, the first stamping inclined surface of the pressing block 130 abuts against the second stamping inclined surface of the pushing block 133. At the same time, the slider 132 of the positioning plate 131 slides along the positioning groove 134. When the first sliding surface 132a is located at the guide surface 134a, the pressing block 130 and the positioning plate 131 push the pushing block 133 along the flange 302. The pressing plate 137 moves in two directions and presses against the two material pieces 30. When the second sliding surface 132b is located at the locking surface 134b, it limits the depth of the hole formed by the piercing head 136a on the flange 302 and pierces the flange 302. After piercing, the pressing block 130 is lifted, and the compression spring 138, due to its elastic return, pushes the block 133 to move away from the two material pieces 30, preparing for the next processing. This achieves both stable fixation of the material pieces 30 and ensures the precision of the piercing. For precision, the demolding zone 14 first abuts against the top head 141 at the connection point of the two material sheets 30, adjusting the position of the two material sheets 30 relative to the fixed mold base 2. Then, the cutter 145 cuts the connection point of the material sheets 30 to form an independent product, ensuring the precision of the cutting.
