Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing technology, specifically to an automated material plate positioning mold. Background Technology

[0002] In fully automated blanking die production lines, stable feeding and precise positioning of the blank are crucial for ensuring blanking quality and preventing die damage. Traditional blanking dies suffer from two major problems: First, blank positioning relies entirely on manual labor, which is inefficient, inconsistent, time-consuming, and labor-intensive. Second, they generally employ simple rigid structures such as guide pins, which are prone to puncturing the blank or damaging the die due to feeding pitch deviations. Third, the dies lack real-time positioning detection capabilities; if the blanking action is initiated before the blank is in place, die collision failures are likely to occur. Utility Model Content

[0003] This utility model provides an automated material plate positioning mold, which solves the problems of low feeding and positioning accuracy and reliance on manual calibration in traditional blanking molds. The technical solution is as follows:

[0004] An automated material plate positioning mold includes a positioning structure and corresponding upper and lower mold bases. The upper surface of the lower mold base has a horizontally extending feed guide rail, which supports the material plate and guides it from the feed end to the discharge end. The positioning structure includes a marking component near the feed end and a stationary plate assembly near the discharge end. The marking component includes a first punch on the upper mold base and a first punch hole on the lower mold base, the first punch and the first punch hole being movable relative to each other to punch a cut on the side skirt of the material plate. The stationary plate assembly includes a sensing element on the lower mold base, a base, and... The system includes a sliding rod and a spring located between the base and the sliding rod. The sensing element is fixed on the base. The sliding rod slides through the base, with the through portion corresponding to the sensing element. Under the action of the spring, the sliding rod slides away from the base. When the material plate moves on the feed guide rail, the sliding rod can switch to a retracted state that interacts with the side skirt of the material plate, or an ejected state that engages with the cut of the material plate under the action of the return spring. When the sliding rod is in the retracted state, the sensing part of its through portion is misaligned with the sensing element. When the sliding rod is in the ejected state, the material plate is limited and the sensing part corresponds to the sensing element, so that the sensing element outputs a positioning signal.

[0005] Preferably, the slide bar has a locking head adapted to the cut; one side of the cut is perpendicular to the direction of material plate movement; when the locking head of the slide bar enters the cut and acts, the side abuts against the locking head, restricting the reverse movement of the material plate.

[0006] Preferably, the cut also has a guide bevel, which is set at an angle to the direction of material plate movement.

[0007] Preferably, the card head is configured in a right-angled trapezoidal shape.

[0008] Preferably, the upper die holder is further provided with an upper insert, and the lower die holder is further provided with a lower insert, the upper insert and the lower insert being vertically offset and corresponding; after the sensor outputs a positioning signal, the upper die holder moves downward, causing the upper insert and the lower insert to move relative to each other to punch the material plate.

[0009] Preferably, the feeding guide rail includes a slide rail, rollers, and a movable spring located below the slide rail, with the rollers rotatably connected to the slide rail; the upper mold base is provided with a stop block corresponding to the slide rail; when the upper mold base moves upward, the movable spring pushes the slide rail upward, and the material plate is supported above the rollers inside the slide rail; when the upper mold base moves downward, the stop block presses against the slide rail and drives the slide rail to move downward, so that the material plate is removed from the roller support and is supported by the lower insert.

[0010] Preferably, it further includes a fine-tuning structure, which includes a second punch and a positioning pin disposed on the upper die base and a second punch disposed on the lower die base. The head of the positioning pin is configured as a sloping cone. The second punch and the second punch can move relative to each other to punch out a fine-tuning hole on the side skirt of the material plate. When the upper die base moves downward, the positioning pin is inserted into the fine-tuning hole and the position of the material plate is adjusted by the guiding action of the sloping cone.

[0011] Preferably, the bottom of the base has a through hole, the depth of which extends perpendicular to the direction of material plate movement, and the slide rod is located inside the through hole and slidably connected to the base.

[0012] Preferably, the upper end face of the slide rod has a limiting groove, which interacts with the inner wall of the base to limit the displacement stroke of the slide rod on the base.

[0013] Preferably, the feeding end of the lower mold base is provided with two opposing guide wheels, the axis of which is perpendicular to the horizontal plane; the material plate moves between the two guide wheels.

[0014] As can be seen from the above description of this utility model, compared with the prior art, this utility model has the following beneficial effects:

[0015] (1) This utility model provides an automated material plate positioning mold. The marking component generates positioning cuts, and the plate fixing component realizes mechanical limit constraint and positioning signal detection of the material plate. It can achieve full automation without relying on manual calibration, which is highly efficient. At the same time, the positioning signal output by the plate fixing component can also be linked with the die punching action to avoid starting the punching when the material plate is not in place, effectively protecting the die components, adapting to the production needs of automatic lines, improving productivity and reducing production costs.

[0016] (2) In this technical solution, the contact structure between the slide bar head and the vertical side of the cut can effectively limit the reverse movement of the material plate after feeding, prevent the positioning deviation caused by the material plate retreating and destroying the positioning reference, and thus lead to punching defects, thereby improving production stability.

[0017] (3) In this technical solution, the guide bevel of the cut can guide the slide bar chuck to smoothly enter the cut. Even if there is a small step error in the feeding of the material plate, it can avoid the hard collision between the chuck and the cut, reduce the risk of slide bar jamming, and effectively maintain the continuous operation of the production line.

[0018] (4) In this technical solution, the right-angled trapezoidal card head can be guided into position by the trapezoidal hypotenuse and the right-angled side can be guided into position by the vertical side. The right-angled side can be guided into position by the vertical side. The guiding and anti-retraction functions are integrated in a single structure. No additional parts are required, which simplifies a large number of mechanical structures and reduces manufacturing costs.

[0019] (5) In this technical solution, the second punch and the second punch automatically punch out the fine adjustment hole, and the slanted cone-shaped positioning pin compensates for the slight positioning deviation of the plate assembly on the material plate through the guiding effect, thereby further improving the positioning accuracy.

[0037] Please see Figures 1 to 9 .

[0038] This embodiment provides an automated material plate positioning mold, which solves the problems of low feeding and positioning accuracy and reliance on manual calibration in traditional blanking molds. This embodiment mainly includes a positioning structure and corresponding upper mold base 1 and lower mold base 2; see [link to documentation]. Figure 1 and Figure 2 The upper surface of the lower mold base 2 has a horizontally extending feed guide rail 21, which supports the material plate 4 and guides the material plate 4 to move from the feed end to the discharge end; the positioning structure includes a marking component 31 near the feed end and a fixed plate component 32 near the discharge end; wherein,

[0039] Marker component 31, see Figure 6 It includes a first punch 311 disposed on the upper die holder 1 and a first punch 312 disposed on the lower die holder 2. The first punch 311 and the first punch 312 are movable relative to each other. See [link / reference] Figure 3 Cut a notch 41 on the side skirt of the material plate 4;

[0040] Fixed plate assembly 32, see Figures 3 to 5 It includes a sensing element 321 with a lower mold base 2, a base 322, a sliding rod 323, and a spring located between the base 322 and the sliding rod 323. The sensing element 321 is fixed on the base 322. The bottom of the base 322 has a through hole 322a. The depth extension direction of the through hole 322a is perpendicular to the movement direction of the material plate 4. The sliding rod 323 is slidably connected to the base 322 through it, and the through part corresponds to the sensing element 321. Under the action of the spring, the sliding rod 323 slides away from the base 322.

[0041] In this embodiment, see Figure 3 When the material plate 4 moves on the feed guide rail 21, the slide rod 323 can be switched to a contracted state that interacts with the side skirt of the material plate 4 under the action of the material plate 4. See [link to relevant documentation]. Figure 4Or, under the action of the return spring 324, in an ejected state that engages with the cut 41 of the material plate 4; the upper end face of the slide rod 323 has a limiting groove 323b, which interacts with the inner wall of the base 322 to limit the displacement stroke of the slide rod 323 on the base 322; see Figure 3 When the slider 323 is in the retracted state, the contact part of its through-hole is misaligned with the sensor 321; see also Figure 4 When the slide bar 323 is in the ejected state, the material plate 4 is limited and the sensing part corresponds to the sensing element 321, so that the sensing element 321 outputs a positioning signal.

[0042] In this embodiment, the sensing element 321 is mainly a limit switch or a proximity switch, etc. If the sensing element 321 is a limit switch, when the slide rod 323 is in the ejected state, the contact part of the exposed through part of the slide rod 323 will correspond to and resist the sensing element 321 (such as the spring of the limit switch). The trigger end of the sensing element 321 will send a control signal to the machine control console. After receiving the signal, the control console will drive the upper mold base 1 of the mold to move downward. If the sensing element 321 is a proximity switch, when the slide rod 323 is in the ejected state, the contact part of the exposed through part of the slide rod 323 moves to the detection range of the proximity switch and corresponds to it. After the contact part is detected within the detection range of the proximity switch, the internal circuit is triggered and sends an electrical control signal to the machine control console. After receiving the signal, the control console will drive the upper mold base 1 of the mold to move downward.

[0043] In this embodiment, see Figure 3 The slide bar 323 has a locking head 323a that matches the cut 41; that is, the shape of the locking head 323a matches the shape of the cut 41, and the locking head 323a is configured as a right-angled trapezoid. One side 41a of the cut 41 is perpendicular to the direction of movement of the material plate 4; see [link to other documentation]. Figure 4 When the locking head 323a of the slide bar 323 enters the cut 41, the side 41a abuts against the locking head 323a, restricting the reverse movement of the material plate 4. The cut 41 also has a guide bevel 41b, which is set at an angle to the direction of movement of the material plate 4. The guide bevel 41b of the cut 41 can guide the locking head 323a of the slide bar 323 to smoothly enter the cut 41. Even if there is a small step error in the feeding of the material plate 4, the locking head 323a can be avoided from hard collision with the cut 41.

[0044] In this embodiment, see Figure 1 and Figure 7 The upper mold base 1 is also provided with an upper insert 11, and the lower mold base 2 is also provided with a lower insert 22. The upper insert 11 and the lower insert 22 are staggered and correspond to each other. After the sensor 321 outputs a positioning signal, the upper mold base 1 moves downward, causing the upper insert 11 and the lower insert 22 to move relative to each other (using staggered shear force) to punch the material plate 4.

[0045] In this embodiment, see Figure 1 The feeding guide rail 21 includes a slide rail 211, a roller 212, and a movable spring (not shown) located below the slide rail 211. The roller 212 is rotatably connected to the slide rail 211. The upper die base 1 is provided with a stop block corresponding to the slide rail 211. When the upper die base 1 moves upward, the movable spring pushes the slide rail 211 upward, and the material plate 4 is supported above the roller 212 inside the slide rail 211. When the upper die base 1 moves downward, the stop block presses against the slide rail 211 and drives the slide rail 211 to move downward, so that the material plate 4 is separated from the support of the roller 212 and supported by the lower insert 22. The downward movement of the slide rail 211 can effectively avoid interference with the lower insert 22, ensuring that the lower insert 22 and the upper insert 11 can move relative to each other, and improving the punching stability.

[0046] In this embodiment, see Figures 6 to 9 It also includes a fine-tuning structure 5, which includes a second punch 51 and a positioning pin 53 located on the upper die base 1, and a second punch 52 located on the lower die base 2. The head of the positioning pin 53 is configured as a beveled cone. See also Figure 3 The second punch 51 and the second punch hole 52 can move relative to each other to punch out a fine-tuning hole 42 on the side skirt of the material plate 4. When the upper die holder 1 moves downward, the positioning pin 53 is inserted into the fine-tuning hole 42 and adjusts the position of the material plate 4 by the guiding action of the inclined cone head. In this embodiment, the inclined cone-shaped positioning pin 53 compensates for the slight positioning deviation of the fixed plate assembly 32 on the material plate 4 by the guiding action. That is, the cut 41 of the material plate 4 mainly plays a coarse positioning role by the limiting action of the slide rod 323, while the tapered inclined surface of the positioning pin 53 inserted into the fine-tuning hole 42 of the material plate 4 can make a fine adjustment of a few millimeters, further improving the positioning accuracy.

[0047] In this embodiment, see Figure 1 The feed end of the lower mold base 2 is provided with two opposing guide wheels 23, the axis of which is perpendicular to the horizontal plane; the material plate 4 is located between the two guide wheels 23. Thus, when the material plate 4 moves from the feed end to the discharge end, the skirts on both sides of the material plate 4 will abut against the guide wheels 23. The guide wheels 23 rotate and guide the material plate 4 to slide smoothly without deviation.

[0048] The working principle and usage process of this utility model:

[0049] When using the mold,

[0050] The first step requires initial manual debugging; see [link / reference] Figure 1 and Figure 2 The material plate 4 on the winding machine is manually pulled out and placed between the two guide rollers 23, so that the material plate 4 is placed stably on the feed guide rail 21 of the lower die base 2; the winding machine is started, and the winding machine rotates to drive the material plate 4 to move from the feed end to the discharge end along the feed guide rail 21. The guide rollers 23 laterally limit the material plate 4 to prevent the material plate 4 from deviating.

[0051] The second step involves manually controlling the upper mold base 1 to descend for the first time when the movement reaches a certain distance (below the marker component 31 and the fine-tuning structure 5). (See below.) Figure 6 The first punch 311 of the upper die holder 1 punches the material plate 4 simultaneously relative to the first punch hole 312 and the second punch 51 punches the material plate 4 relative to the second punch hole 52, respectively punching out the marking cut 41 for coarse positioning and the fine adjustment hole 42 for precision positioning on the material plate 4; after punching, the upper die holder 1 is manually controlled to move upward and reset, and the coiling machine restarts to drive the material plate 4 to continue moving towards the discharge end.

[0052] Third step, during the continued movement of material plate 4, see... Figure 3 During this process, the side skirt of the material plate 4 will continuously press against the clip 323a of the slide rod 323, causing the slide rod 323 to slide along the through hole 322a of the base 322 towards the base 322. The return spring 324 on the rear side of the slide rod 323 is compressed and stored, forming a compressed state. At this time, the sensing part on the free end of the slide rod 323 is misaligned with the sensing element 321. The sensing element 321 will transmit the signal that the material plate 4 is not in place to the machine control console. After receiving the signal, the control console will issue a lock command to prevent the upper die base 1 from moving downward, thus avoiding accidental punching.

[0053] Step 4, see Figure 4 When the material plate 4 continues to move until the coarse positioning cut 41 corresponds to the locking head 323a of the slide rod 323, the squeezing force of the side skirt of the material plate 4 on the slide rod 323 disappears, the return spring 324 releases its stored energy, and pushes the slide rod 323 to slide towards the material plate 4 and lock into the cut 41 to form an ejection state; at the same time, the sensing part on the free end of the slide rod 323 corresponds to the sensing element 321. After the sensing element 321 detects the sensing part, the internal circuit is triggered and sends a control signal to the machine control console to indicate the position; after receiving the signal, the control console drives the upper mold base 1 of the mold to move downward for the second time (the control console will also send a stop operation signal to the coiler at the same time).

[0054] Fifth, when the upper die holder 1 descends for the second time, the positioning pin 53 of the upper die holder 1 will preferentially insert into the fine-tuning hole 42, and compensate for the small step error of the material plate 4 feeding through the inclined guide action, so as to achieve precise positioning. After positioning, the upper die holder 1 continues to descend, driving the upper insert 11 and the lower insert 22 of the lower die holder 2 to move relative to each other, and punching and cutting the material plate 4. After punching, the upper die holder 1 automatically moves upward to reset, and the machine control console sends a restart signal to the coiler. The material plate 4 continues to move, and the subsequent operation is fully automated. In summary, this utility model uses the marking component 31 to process and generate the positioning cut 41, and then uses the fixed plate component 32 to realize the mechanical limit constraint and positioning signal detection of the material plate 4. It can achieve full automation without relying on manual calibration, which is highly efficient. At the same time, the positioning signal output by the fixed plate component 32 can also be linked with the punching action of the die to avoid starting the punching before the material plate 4 is in place, effectively protecting the die components, adapting to the production needs of automatic lines, improving productivity, and reducing production costs.

[0055] The foregoing description of the specifications and embodiments is intended to explain the scope of protection of this utility model, but does not constitute a limitation on the scope of protection of this utility model. Modifications, equivalent substitutions, or other improvements to the embodiments of this utility model or a portion thereof that can be obtained by those skilled in the art through logical analysis, reasoning, or limited experimentation, based on the teachings of this utility model or the foregoing embodiments, should all be included within the scope of protection of this utility model.
