Description

Technical Field

[0001] This utility model relates to the field of profile punching technology, specifically to a double-sided punching machine. Background Technology

[0002] Punching is a common process in the manufacturing of metal sheets, pipes, profiles, and other workpieces, widely used in industries such as construction, automotive, home appliances, electronics, and hardware. With increasing product complexity and higher production efficiency requirements, the demand for double-sided or multi-position simultaneous or continuous punching of workpieces is growing. Traditional single-sided punching equipment (such as ordinary punch presses or single-head punching machines) typically punches one side of the profile first, then flips the profile over for re-punching, a cumbersome and inefficient process.

[0003] Therefore, existing technologies need further development. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and provide a double-sided punching machine to solve the technical problem that the relevant technology usually punches one side of the profile first, and then flips the profile over to punch it again, which is cumbersome and has low production efficiency.

[0005] To achieve the above technical objectives, the present invention adopts the following technical solution: a double-sided punching machine is provided, comprising: a lower die core, on which a machining through hole is formed; a die cavity located at the bottom of the lower die core; a punching assembly having a driving part and a punching part, the punching part being movably disposed, the driving part being drivenly connected to the punching part for driving the punching part to move toward or away from the lower die core; wherein, when the punching part moves toward the lower die core and contacts the die cavity, the punching part punches holes on both sides of the profile placed on the lower die core.

[0006] Furthermore, the punching assembly includes: a drive member that extends and retracts toward the lower die core; and a punch, the drive member being driven to connect with the punch so as to drive the punch to move along the machined through hole and abut against the die to punch both sides of the profile placed on the lower die core.

[0007] Furthermore, the double-sided punching machine also includes: an anti-deformation component, which has a connecting part and an anti-deformation part. The connecting part is connected to the punching part, and the side of the connecting part away from the punching part is connected to the driving part. The anti-deformation part is movably disposed relative to the connecting part, and a first clearance hole is provided on the anti-deformation part. The punching part is movably disposed within the first clearance hole. The driving part is used to drive the connecting part, the punching part, and the anti-deformation part to move together toward the lower die core until the anti-deformation part abuts against the profile. After that, the driving part continues to drive the connecting part and the punching part to move relative to the anti-deformation part and toward the lower die core, so that the punching part passes through the first clearance hole and punches both sides of the profile.

[0008] Further, the anti-deformation component includes: an upper template connected to the punching section, with the side of the upper template away from the punching section connected to the drive unit; an anti-deformation plate movably disposed relative to the upper template, with a first clearance hole provided on the anti-deformation plate. Further, the anti-deformation component also includes: a connector, which sequentially passes through the upper template and the anti-deformation plate, with the anti-deformation plate movably disposed relative to the connector, and the connector connected to the upper template; a spring sleeved on the connector, with both ends of the spring connected to the upper template and the anti-deformation plate respectively. Further, the double-sided punching machine also includes: two vertical plates, both extending along a preset direction, arranged opposite to each other, with the drive unit mounted on the top of the two vertical plates, at least a portion of the lower die core located between the two vertical plates, the extension direction of the lower die core perpendicular to the extension direction of the vertical plates; a guide plate, with both ends connected to the two vertical plates, the punching section movably disposed relative to the guide plate, and the punching section passing through the guide plate.

[0009] Furthermore, the double-sided punching machine also includes two rollers, which are adjustablely arranged on opposite sides of the two vertical plates, with the lower die core located between the two rollers.

[0010] Furthermore, a material discharge hole is provided on the die cavity.

[0011] Furthermore, the double-sided punching machine also includes a positioning component, which includes a fixing part and a positioning part. The positioning part passes through the lower die core and is inserted into the fixing part to position the profile.

[0012] Furthermore, the positioning component includes: a positioning block and a positioning plate. The positioning plate extends along the extension direction of the lower mold core and is located at the bottom of the lower mold core. The lower mold core has multiple first positioning holes, and the positioning plate has multiple second positioning holes. The multiple second positioning holes are spaced apart along the extension direction of the positioning plate. The multiple first positioning holes and the multiple second positioning holes are arranged in a one-to-one correspondence. The positioning block passes through the first positioning hole and is inserted into the second positioning hole.

[0013] Beneficial effects: 1. By setting up a punching assembly with a drive unit and a movable punching unit, as well as a lower die core with a machining through hole, the punching unit can perform the punching action in the single clamping and positioning state of the profile. The punching action punches both sides of the profile in one punching action, which achieves the effect of eliminating the workpiece flipping process and significantly improving production efficiency. The drive unit drives the punching unit to move toward or away from the lower die core, which achieves the effect of precisely controlling the punching stroke and ensuring the reliable completion of the punching action.

[0014] 2. By setting up an anti-deformation component and its relatively movable connecting part and anti-deformation part, and using a drive unit to first drive all three to move down together so that the anti-deformation part presses the profile, and then driving the connecting part and punching part to move down separately to punch, the workpiece is effectively pressed down before punching, preventing the workpiece from deforming or shifting during punching, and ensuring punching accuracy. By opening a first clearance hole on the anti-deformation part for the punching part to pass through, and the shape of the first clearance hole is the same as the processing through hole, the smooth operation of the punching part is ensured and no additional interference is caused to the workpiece.

[0015] 3. By setting a connector through which the upper template and anti-deformation plate are installed, and by making the anti-deformation plate movable along the connector, the movement of the anti-deformation plate relative to the upper template is precisely guided, ensuring its smooth downward pressure. By setting a spring on the connector, with its two ends acting on the upper template and the anti-deformation plate respectively, the upper template and punch are allowed to continue to move independently downward to punch after the anti-deformation plate presses the workpiece, overcoming the spring force. After punching, the restoring force of the spring is used to automatically reset the anti-deformation plate. Through the elastic connection of the spring, a flexible buffer is provided when the anti-deformation plate presses the workpiece, avoiding rigid impact damage to the workpiece surface.

Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0019] According to an embodiment of this utility model, a double-sided punching machine is provided. Please refer to [link / reference]. Figures 1 to 3 The assembly includes: a lower die core 1, on which a machining through hole is provided; a die cavity 16 located at the bottom of the lower die core 1; and a punching assembly 2, which has a driving part and a punching part, the punching part being movably disposed, the driving part being drivenly connected to the punching part for driving the punching part to move toward or away from the lower die core 1; wherein, when the punching part moves toward the lower die core 1 and contacts the die cavity 16, the punching part punches holes on both sides of the profile placed on the lower die core 1, wherein the holes on both sides of the profile are concentric holes.

[0020] By adopting the above technical solution, and by setting up a punching assembly 2 with a driving part and a movable punching part, and a lower die core 1 with a machining through hole, the punching part can perform the punching action in the single clamping and positioning state of the profile. When the punching part moves toward the lower die core 1 and contacts the die 16, a punching action is completed, that is, punching both sides of the profile, thus eliminating the workpiece flipping process and significantly improving production efficiency. By driving the punching part toward or away from the lower die core 1 through the driving part, the punching stroke is precisely controlled, ensuring that the punching action is reliably completed.

[0021] Specifically, the lower die core 1 is mounted on the base plate 4 via the fixed base 3, and the punching assembly 2 is mounted on the base plate 4.

[0022] Furthermore, the lower mold core 1 includes a lower mold and a mold body, and the lower mold and the mold body are detachably connected.

[0023] By adopting the above technical solution, the lower die core 1 is stably installed on the base plate 4 through the fixed base 3, which achieves the effect of enhancing the working stability of the lower die core 1 and ensuring the punching accuracy. By designing the lower die core 1 as a structure in which the lower die and the die body can be detachably connected, it achieves the effect of facilitating the replacement of worn lower dies or adapting to lower dies with different punching requirements, improving the equipment's versatility and ease of maintenance.

[0024] Please refer to Figure 2 The punching assembly 2 includes: a driving member 5, which extends and retracts toward the lower die core 1; and a punch 6, which is driven to move along the through hole and abut against the die 16 to punch both sides of the profile placed on the lower die core 1.

[0025] Furthermore, the drive component 5 is preferably a hydraulic cylinder.

[0026] Furthermore, the shape of the punch 6 is the same as the shape of the through hole being machined.

[0027] The driving component 5 forms the driving part, and the punch 6 forms the punching part.

[0028] By adopting the above technical solution, the punch 6 is directly driven by a retractable drive component 5 (such as a hydraulic cylinder), which achieves the effect of providing stable and strong power for the punching action; by making the shape of the punch 6 the same as the shape of the machining through hole of the lower die core 1, the effect of ensuring accurate punching contour and high punching quality is achieved.

[0029] Please refer to Figure 2 The double-sided punching machine also includes: an anti-deformation component 7, which has a connecting part and an anti-deformation part. The connecting part is connected to the punching part, and the side of the connecting part away from the punching part is connected to the driving part. The anti-deformation part is movably disposed relative to the connecting part, and a first clearance hole is provided on the anti-deformation part. The punching part is movably disposed within the first clearance hole. The driving part is used to drive the connecting part, the punching part, and the anti-deformation part to move together toward the lower die core 1 until the anti-deformation part abuts against the profile. After that, the driving part continues to drive the connecting part and the punching part to move relative to the anti-deformation part and toward the lower die core 1, so that the punching part passes through the first clearance hole and punches both sides of the profile.

[0030] Furthermore, the first clearance hole has the same shape as the machined through hole.

[0031] By adopting the above technical solution, by setting the anti-deformation component 7 and its relatively movable connecting part and anti-deformation part, and by using the driving part to first drive all three to move down together so that the anti-deformation part presses the profile, and then driving the connecting part and the punching part to move down separately to punch, the effect of effectively pressing the workpiece before punching, preventing the workpiece from deforming or displacing during the punching process, and ensuring the punching accuracy is achieved; by opening a first clearance hole on the anti-deformation part for the punching part to pass through, and the shape of the first clearance hole is the same as that of the machining through hole, the effect of ensuring smooth operation of the punching part and not causing additional interference to the workpiece is achieved.

[0032] Please refer to Figure 2 The anti-deformation component 7 includes: an upper template 8, which is connected to the punching part, and the side of the upper template 8 away from the punching part is connected to the driving part; and an anti-deformation plate 9, which is movably disposed relative to the upper template 8, and has a first clearance hole.

[0033] The punching part is movably inserted into the first clearance hole; the driving part is used to drive the upper template 8, the punching part and the anti-deformation plate 9 to move together toward the lower mold core 1 until the anti-deformation plate 9 abuts the profile; then, the driving part continues to drive the upper template 8 and the punching part to move relative to the anti-deformation plate 9 and toward the lower mold core 1, so that the punching part passes through the first clearance hole and punches holes on both sides of the profile.

[0034] The upper template 8 forms the connecting part; the anti-deformation plate 9 forms the anti-deformation part.

[0035] By adopting the above technical solution, by setting the upper template 8 as a connecting part to connect the driving part and the punching part, the driving force is effectively transmitted to the punching part and serves as the motion reference for the anti-deformation plate 9. By setting the anti-deformation plate 9, which is movable relative to the upper template 8, as the anti-deformation part, and opening a first clearance hole on it for the punch 6 to pass through, the anti-deformation plate 9 is used to press the workpiece surface before punching, providing stable support to prevent deformation. The driving part drives the upper template 8 and the punch 6 to continue to move downward relative to the anti-deformation plate 9 that has pressed the workpiece to complete the punching, achieving the effect of precise punching under effective anti-deformation measures.

[0036] Furthermore, the driving component 5 is driven to connect with the upper template 8, and a punch 6 is provided on the side of the upper template 8 away from the driving component 5, with the punch 6 passing through an anti-deformation plate 9.

[0037] Please refer to Figure 2 and Figure 3 The anti-deformation component 7 also includes: a connector 10, which is sequentially fitted with an upper template 8 and an anti-deformation plate 9, the anti-deformation plate 9 being movably disposed relative to the connector 10, and the connector 10 being connected to the upper template 8; and a spring 11, which is sleeved on the connector 10, with both ends of the spring 11 being connected to the upper template 8 and the anti-deformation plate 9, respectively.

[0038] By adopting the above technical solution, by setting the connector 10 through which the upper template 8 and the anti-deformation plate 9 are inserted, and by setting the anti-deformation plate 9 to be movable along the connector 10, the effect of providing precise guidance for the movement of the anti-deformation plate 9 relative to the upper template 8 and ensuring its smooth downward pressing is achieved; by setting the spring 11 sleeved on the connector 10, with its two ends acting on the upper template 8 and the anti-deformation plate 9 respectively, the effect of allowing the upper template 8 and the punch 6 to continue to move independently downward to punch after the anti-deformation plate 9 presses the workpiece is achieved, and the effect of automatically resetting the anti-deformation plate 9 by using the restoring force of the spring 11 after punching is completed is achieved; through the elastic connection of the spring 11, the effect of providing flexible buffer when the anti-deformation plate 9 presses the workpiece is achieved, avoiding rigid impact damage to the surface of the workpiece.

[0039] Preferably, four connectors 10 and springs 11 are provided, and the connectors 10 and springs 11 are spaced apart along the periphery of the anti-deformation plate 9.

[0040] By adopting the above technical solution, and by setting four connecting parts 10 and springs 11 at intervals along the periphery of the anti-deformation plate 9, the anti-deformation plate 9 is subjected to balanced force and moves smoothly, avoiding the effect of tilting and jamming; through multi-point elastic support, the uniformity of the clamping force of the anti-deformation plate 9 on the workpiece is enhanced, and the anti-deformation effect and workpiece stability are further improved.

[0041] Please refer to Figure 3The double-sided punching machine also includes: two upright plates 12, both of which extend along a preset direction and are arranged opposite to each other; a drive unit is installed on the top of the two upright plates 12; at least a portion of the lower die core 1 is located between the two upright plates 12; the extension direction of the lower die core 1 is perpendicular to the extension direction of the upright plates 12; a guide plate 13, both ends of which are connected to the two upright plates 12 respectively; an anti-deformation plate 9 is movably arranged relative to the guide plate 13; a punching part is movably arranged relative to the guide plate 13; and the punching part passes through the guide plate 13.

[0042] Specifically, two upright plates 12 are set on the base plate 4.

[0043] By adopting the above technical solution, by setting two opposing vertical plates 12 with their extension direction perpendicular to the lower die core 1, and installing the drive unit on top of them, a stable support frame is provided for the entire stamping system (drive unit 5, upper die plate 8, punch 6, etc.). By setting a guide plate 13 between the two vertical plates 12 and allowing the anti-deformation plate 9 and the punching part (punch 6) to be movably set relative to the guide plate 13 with the punch 6 passing through it, the effect of providing precise guidance for the up and down movement of the anti-deformation plate 9 and the punch 6, ensuring the linearity of movement and the punching accuracy is achieved. By setting the vertical plates 12 on the base plate 4, the overall structure of the equipment is made stable, rigid, and has strong impact resistance.

[0044] Please refer to Figure 2 The double-sided punching machine also includes two rollers 14, which are adjustablely arranged on opposite sides of the two upright plates 12, with the lower die core 1 located between the two rollers 14. Furthermore, the two rollers 14 are threadedly engaged with two screws 15, which are installed on opposite sides of the two upright plates 12.

[0045] By adopting the above technical solution, by setting two adjustable rollers 14 on opposite sides of the two upright plates 12 and placing the lower mold core 1 between them, the effect of providing rolling support for the long strip profile placed or passing through the lower mold core 1 is achieved, facilitating the feeding and positioning of the profile; by threading the rollers 14 with the screws 15 installed on the upright plates 12, the distance between the two rollers 14 can be easily adjusted, thereby adapting to the processing needs of profiles of different widths.

[0046] Please refer to Figure 2 The die 16 has a material discharge hole.

[0047] By adopting the above technical solution, by setting a die 16 with a material discharge hole at the bottom of the lower die core 1, the waste generated by punching is received and discharged smoothly through the material discharge hole, thus avoiding the accumulation of waste and affecting continuous processing.

[0048] Specifically, the die 16 is set on the base plate 4, and the base plate 4 has a discharge hole, which is set in correspondence with the material leakage hole.

[0049] By adopting the above technical solution, by setting the die 16 on the base plate 4 and making the discharge hole on the base plate 4 correspond to the leakage hole of the die 16, the effect of constructing a continuous waste discharge channel is achieved, ensuring that the waste is discharged from the equipment efficiently and smoothly, which facilitates waste collection and treatment.

[0050] Please refer to Figure 1 The double-sided punching machine also includes a positioning component 17, which includes a fixing part and a positioning part. The positioning part passes through the lower die core 1 and is inserted into the fixing part to position the profile through the positioning part.

[0051] By adopting the above technical solution, and by setting the positioning component 17, the positioning part can pass through the lower die core 1 and be inserted into the fixing part, thereby achieving the effect of accurately positioning the profile placed on the lower die core 1 and ensuring the accuracy of the punching position.

[0052] Please refer to Figure 2 The positioning component 17 includes a positioning block 18 and a positioning plate 19. The positioning plate 19 extends along the extension direction of the lower mold core 1 and is disposed at the bottom of the lower mold core 1. The lower mold core 1 has a plurality of first positioning holes, and the positioning plate 19 has a plurality of second positioning holes. The plurality of second positioning holes are spaced apart along the extension direction of the positioning plate 19. The plurality of first positioning holes and the plurality of second positioning holes are arranged one-to-one. The positioning block 18 passes through the first positioning hole and is inserted into the second positioning hole.

[0053] The positioning block 18 forms a positioning part; the positioning plate 19 forms a fixing part.

[0054] Furthermore, a proximity switch 20 is detachably provided on the positioning plate 19. When the profile abuts against the positioning block 18, the proximity switch 20 is triggered, the drive component 5 is activated, and the punch 6 passes through one side of the profile, the lower die core, and the other side of the profile in sequence until it abuts against the die 16, so as to complete the punching of both sides of the profile sleeved on the lower die core 1.

[0055] By adopting the above technical solution, and by setting a positioning plate 19 arranged along the extension direction of the lower die core 1 and a positioning block 18 that can be selectively inserted into the combination of the first positioning hole and the second positioning hole at different positions, the positioning point position can be flexibly adjusted in the length direction of the lower die core 1 to adapt to the needs of different length profiles or different punching positions. By setting a detachable proximity switch 20 on the positioning plate 19 and triggering it when the profile moves to abut against the positioning block 18, the automatic detection of the profile's arrival and precise control of the timing of the start of the punching action of the drive component 5 are achieved, realizing the effect of automated processing. The detachable setting of the proximity switch 20 facilitates the adjustment of its installation point according to the position of the positioning block 18 and ensures the accuracy of detection.

[0056] Working principle: At the start of the operation, the operator adjusts the positioning block 18 according to the actual punching position, and achieves positioning by adjusting the positioning block 18 to be inserted into the second positioning hole at different positions on the positioning plate 19; then the operator feeds the profile to be processed (such as pipe or profile) into the equipment along the extension direction of the lower die core 1, so that the profile is placed on the lower die core 1 between the two vertical plates 12, and pushes the profile so that its end or designated position abuts against the positioning block 18 inserted in the first positioning hole of the lower die core 1; at this time, the proximity switch 20 installed on the positioning plate 19 detects the profile positioning signal and triggers it, the control system starts the drive component 5 to extend downward, and drives the upper template 8 connected to the drive component 5, the punch 6 fixed to the bottom of the upper template 8, and the anti-deformation plate 9 elastically connected to the upper template 8 through the connector 10 and the spring 11 to move downward synchronously; the anti-deformation plate 9 first contacts the upper surface of the profile and applies a clamping force. After the profile is fully clamped, the drive component 5 continues to push the upper template 8 and punch 6 to move independently downward relative to the anti-deformation plate 9, overcoming the elastic force of the spring 11. The punch 6 passes through the first clearance hole of the anti-deformation plate 9 and the guide hole of the guide plate 13. Then, the punch 6 passes through one side of the profile, the lower die core, and the other side of the profile in sequence until it abuts against the die 16 to complete the punching of both sides of the profile sleeved on the lower die core 1. The punching waste passes through the processing through hole of the lower die core 1 and falls into the discharge hole of the die 16, and is then discharged through the discharge hole of the bottom plate 4. After the punching is completed, the drive component 5 retracts, driving the upper template 8 and punch 6 to rise. At this time, the spring 11 drives the anti-deformation plate 9 to reset and detach from the workpiece surface. The operator takes out the processed profile, and the equipment returns to standby mode to wait for the next processing cycle.
