Description

Technical Field

[0001] The utility model relates to the technical field of die processing, and particularly relates to a calibration mechanism for the punching depth of a punching die head. Background Technique

[0002] A die is usually composed of an upper die and a lower die, and is used for forming materials under the action of a press. The punching and pasting work of the punching die is to process metal sheets through a stamping machine (such as a punching press) to produce required parts or products. The working process of punching and pasting the punching die is a precise operation process involving multiple steps. It is a pressure processing method that uses a die installed on a stamping device (mainly a press) to apply a certain pressure to materials (metal or non-metal sheets), causing them to separate or form, so as to obtain parts with certain dimensional requirements and qualified appearance quality.

[0003] Since the sizes of the die punches on site may be different, and the installation methods of different die punches are also different, before the punching and pasting processing of the die, the operator needs to first install the die, and then start the stamping machine to perform the punching and pasting processing on the workpiece.

[0004] Due to the non-uniform size or different installation methods of the die punches on site, and generally the operator manually sets the punching depth in the control program. The operator operates the device manually, which easily leads to great differences in the actual use effects of the punching and pasting machine. Therefore, it is necessary to propose a calibration mechanism for the punching depth of a punching die head. Content of the Utility Model

[0005] The purpose of the utility model is to provide a calibration mechanism for the punching depth of a punching die head to solve the problems raised in the above background technique.

[0006] To solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A calibration mechanism for the punching depth of a punching die head includes a base; an installation plate is fixedly installed at the top of the base, one end of the installation plate is fixedly connected with a slide cylinder, a calibration platform is fixedly installed at the top of the slide cylinder, one end of the slide cylinder is detachably installed with an induction stop piece through a pair of fixing bolts, one side of the installation plate is fixedly connected with a fixing plate, a sensor is fixedly installed at one end of the fixing plate, a control panel is fixedly connected to one end of the fixing plate at the bottom of the sensor, a part of the induction stop piece close to one side extends into the interior of the sensor, and an auxiliary component is arranged on the other side of the installation plate, and the auxiliary component is used for assisting in calibrating the height adjusted by the slide cylinder.

[0008] After the die head contacts the top of the calibration platform, the die head can slowly press the calibration platform downward, so that the slide cylinder can shrink and drive the sensing baffle to move downward synchronously. After the sensing baffle is pushed to the inside of the sensor, the sensor immediately sends a signal to the control panel, and the control panel controls the slide cylinder to stop shrinking, so that the die head stops moving. At this time, by observing the specific position of the pointer block pointing to the scale line, the user can know the current Z-axis position data of the die head, so as to use the slide cylinder to automatically adjust the depth of the die head in the future, so as to avoid the mold depth exceeding the tolerance and affecting the subsequent mold processing effect.

[0009] A further improvement of the technical solution of the utility model is that the auxiliary component includes a fixing frame, which is fixedly connected to the surface of the other side of the mounting plate, a connecting frame is fixedly installed on the other side of the mounting plate at the bottom of the fixing frame, the fixing frame and the connecting frame are fixedly connected through a measuring plate, a scale line is attached to one end of the measuring plate, a pointer block is installed at one end of the slide cylinder through a bolt thread, the pointer block is located at the bottom of the sensing baffle, and the other side of the pointer block is close to the scale line.

[0010] The above technical solution is adopted. In this solution, if the sensor fails or is damaged, the die head can be used to slowly press down the calibration platform. At the same time, the specific position of the scale line pointed by the pointer block is constantly observed, so that the user can know the current Z-axis position data of the die head until the die head is calibrated to the correct depth, thereby expanding the performance of the device.

[0011] A further improvement of the technical solution of the utility model is that a pair of limit plates are fixedly installed at one end of the slide cylinder on the top of the induction baffle, and a baffle is provided at one end of the induction baffle, which baffles are in contact with the surface of one end of each fixing bolt, and a pair of sliding blocks are fixedly installed on the top of one side of the baffle, and a sliding groove matching the shape of the sliding block is provided inside each limit plate, and each sliding block is respectively slidably connected to the inside of each limit plate, and a supporting component for supporting the bottom of the fixing bolt is provided inside the baffle near the bottom.

[0012] The above-mentioned technical scheme is adopted. In this scheme, after the induction baffle is installed by using the fixing bolt, the baffle is pushed downward so that the baffle is blocked at one end of the fixing bolt, and the sliding trajectory of the baffle at one end of the limit plate can be guided and limited by installing a slider, so as to ensure that the baffle can only move upward or downward, thereby preventing the slide cylinder from vibrating during use and causing the fixing bolt to loosen, thereby causing the position of the induction baffle to shift, thereby preventing errors in the calibration work of the punch die head.

[0013] A further improvement of the technical solution of the present utility model lies in that: the supporting member includes a pair of supporting blocks, each supporting block is slidably connected to the inside of the baffle, and each supporting block is respectively in contact with the surface of the bottom of each fixing bolt. One end of each supporting block is fixedly installed with a connecting rod, each connecting rod passes through one end of the baffle and is fixedly connected to a connecting plate. A pair of springs are fixedly installed inside the baffle, and each spring is respectively located around each connecting rod and is fixedly connected to one end of each supporting block.

[0014] With the above technical solution, in this solution, the elastic force of the spring can squeeze the supporting block towards the other end, so that the supporting block can hold the bottom of the fixing bolt, thereby preventing the fixing bolt from coming off, and further playing a role of limiting and strengthening the fixing bolt.

[0015] A further improvement of the technical solution of the present utility model lies in that: a pulling block is fixedly installed at one end of each connecting plate.

[0016] With the above technical solution, in this solution, by installing the pulling block, the contact area between the user's hand and the connecting plate can be enlarged, and then it is convenient to pull the connecting plate towards one end, so that the supporting block is separated from the bottom of the fixing bolt.

[0017] A further improvement of the technical solution of the present utility model lies in that: the lower surface of the supporting block is set as an inclined surface that slopes towards the bottom of the other end.

[0018] With the above technical solution, in this solution, by setting the lower surface of the supporting block as an inclined surface that slopes towards the bottom of the other end, when the baffle is located above the fixing bolt, the baffle drives the supporting block to move downward, and the inclined surface of the supporting block can first come into contact with the two fixing bolts, thereby being able to squeeze the inclined surface, causing the supporting block to automatically move towards one end, so as to facilitate the downward movement of the baffle, thus reducing the operation steps and improving the work efficiency.

[0019] A further improvement of the technical solution of the present utility model lies in that: an anti-slip pad is attached to the surface of one end of the baffle, and the anti-slip pad is located on top of each connecting plate.

[0020] With the above technical solution, in this solution, by installing the anti-slip pad, the friction between the hand and the surface of one end of the baffle can be increased, and then it is convenient to manually move the baffle up or down, providing convenience for the operation of the user.

[0021] Due to the adoption of the above technical solution, the technical progress achieved by the present utility model compared with the prior art is:

[0022] 1. The utility model provides a calibration mechanism for the punching depth of a punching die head. Through the mutual cooperation between a sensor and an induction flapper, during the process of the punching die head slowly pressing down on the calibration platform, it can drive the slide cylinder to continuously contract and drive the induction flapper to move downward synchronously. After pushing the induction flapper into the interior of the sensor, it can trigger the induction signal of the sensor, causing the punching die head to immediately stop moving. At this time, by reading the Z-axis position data of the current punching die head and comparing it with the standard Z-axis data, the depth of the Z-axis punching die head is automatically adjusted according to the difference, and the adjusted depth is the correct depth, thus avoiding the influence of the over-tolerance of the die depth on the subsequent die processing effect.

[0023] 2. The utility model provides a calibration mechanism for the punching depth of a punching die head. Through the mutual cooperation between auxiliary components, when the sensor fails, it can separately determine the position of the punching die head by observing the different specific positions where the pointer points to the scale line, thereby realizing the auxiliary calibration of the depth of the die punch and expanding the use performance of the device.

[0024] 3. The utility model provides a calibration mechanism for the punching depth of a punching die head. By setting a baffle and a support block, it can respectively block and limit the bottom of one end of the fixing bolt, thereby preventing the slide cylinder from vibrating during use and causing the fixing bolt to become loose, and further causing the position of the induction flapper to shift, thus preventing errors in the calibration work of the punching die head and improving the die processing effect.

[0033] The following further describes the present utility model in detail with reference to the embodiments:

[0034] Embodiment 1

[0035] As Figure 1 , Figure 2 and Figure 3 shown, the present utility model provides a die head punching depth calibration mechanism, including a base 1; a mounting plate 2 is fixedly installed on the top of the base 1, one end of the mounting plate 2 is fixedly connected with a slide cylinder 3, a calibration platform 8 is fixedly installed on the top of the slide cylinder 3, one end of the slide cylinder 3 is detachably installed with an induction baffle 7 through a pair of fixing bolts 701, one side of the mounting plate 2 is fixedly connected with a fixing plate 201, a sensor 6 is fixedly installed at one end of the fixing plate 201, one end of the fixing plate 201 at the bottom of the sensor 6 is fixedly connected with a control panel 4, a part of the induction baffle 7 near one side extends into the interior of the sensor 6, and an auxiliary component 5 is arranged on the other side of the mounting plate 2, and the auxiliary component 5 is used for performing auxiliary calibration processing on the height adjusted by the slide cylinder 3. The auxiliary component 5 includes a fixing frame 501, and the fixing frame 501 is fixedly connected with the surface of the other side of the mounting plate 2. A connecting frame 502 is fixedly installed on the other side of the mounting plate 2 at the bottom of the fixing frame 501. The fixing frame 501 and the connecting frame 502 are fixedly connected through a measuring plate 504. A scale line 505 is attached to one end of the measuring plate 504. One end of the slide cylinder 3 is threadedly installed with a pointer block 503 through a bolt 506. The pointer block 503 is located at the bottom of the induction baffle 7, and the other side of the pointer block 503 is close to one side of the scale line 505.

[0036] In this embodiment, after the die head contacts the top of the calibration platform 8, the die head can slowly press down the calibration platform 8, enabling the slide cylinder 3 to contract and driving the sensing flap 7 to move downward synchronously. After the sensing flap 7 is pushed into the sensor 6, the sensor 6 immediately sends a signal to the control panel 4, and the control panel 4 controls the slide cylinder 3 to stop contracting, causing the die head to stop moving. At this time, by observing the specific position where the pointer block 503 points to the scale line 505, it is convenient for the user to know the Z-axis position data of the current die head, so as to subsequently automatically adjust the depth of the die head by using the slide cylinder 3, avoiding the influence of the excessive die depth on the subsequent die processing effect.

[0037] Embodiment 2

[0038] As Figure 2 、 Figure 4 and Figure 5 shown, on the basis of Embodiment 1, the present utility model provides a technical solution: Preferably, a pair of limit plates 10 are fixedly installed at one end of the slide cylinder 3 at the top of the sensing flap 7. A baffle 9 is provided at one end of the sensing flap 7, and the baffle 9 is in contact with the surface of one end of each fixing bolt 701. A pair of sliders 901 are fixedly installed at the top of one side of the baffle 9. A chute matching the shape of the slider 901 is provided inside each limit plate 10, and each slider 901 is slidably connected to the inside of each limit plate 10. A support member 11 for supporting the bottom of the fixing bolt 701 is provided inside the baffle 9 near the bottom. The support member 11 includes a pair of support blocks 1101, each support block 1101 is slidably connected to the inside of the baffle 9, and each support block 1101 is in contact with the surface of the bottom of each fixing bolt 701. A connecting rod 1104 is fixedly installed at one end of each support block 1101, each connecting rod 1104 passes through one end of the baffle 9 and is fixedly connected to a connecting plate 1103. A pair of springs 1102 are fixedly installed inside the baffle 9, each spring 1102 is respectively located around each connecting rod 1104 and is fixedly connected to one end of each support block 1101. A pull block 1105 is fixedly installed at one end of each connecting plate 1103.

[0039] In this embodiment, after the induction flap 7 is installed using the fixing bolt 701, by toggling the baffle 9 downward, the baffle 9 is blocked at one end of the fixing bolt 701. Among them, by installing the sliding block 901, the sliding trajectory of the baffle 9 at one end of the limiting plate 10 can be guided and limited, so as to ensure that the baffle 9 can only move upward or downward, thereby preventing the fixing bolt 701 from loosening due to vibration during the use of the sliding table cylinder 3, and further preventing the position of the induction flap 7 from shifting, and further preventing errors in the calibration work of the punching die head. Through the elastic force of the spring 1102, the supporting block 1101 can be squeezed toward the other end, so that the supporting block 1101 can hold the bottom of the fixing bolt 701, thereby preventing the fixing bolt 701 from detaching, and further playing a role of limiting and strengthening the fixing bolt 701. By installing the pulling block 1105, the contact area between the user's hand and the connecting plate 1103 can be enlarged, which is convenient for pulling the connecting plate 1103 toward one end, so that the supporting block 1101 is separated from the bottom of the fixing bolt 701.

[0040] Embodiment 3

[0041] As Figure 5 and Figure 6 shown, on the basis of Embodiment 2, the present utility model provides a technical solution: Preferably, the lower surface of the supporting block 1101 is set as an inclined surface that slopes toward the bottom of the other end.

[0042] In this embodiment, by setting the lower surface of the supporting block 1101 as an inclined surface that slopes toward the bottom of the other end, when the baffle 9 is located on top of the fixing bolt 701, the baffle 9 drives the supporting block 1101 to move downward. The inclined surface of the supporting block 1101 can first come into contact with the two fixing bolts 701, so as to squeeze the inclined surface, causing the supporting block 1101 to automatically move toward one end, so as to facilitate moving the baffle 9 downward, thereby reducing the operation steps and improving the work efficiency.

[0043] Embodiment 4

[0044] As Figure 1 and Figure 5 shown, on the basis of Embodiment 3, the present utility model provides a technical solution: Preferably, an anti-slip pad 902 is attached to the surface of one end of the baffle 9, and the anti-slip pad 902 is located on top of each connecting plate 1103.

[0045] In this embodiment, by installing the anti-slip pad 902, the friction between the hand and the surface of one end of the baffle 9 can be increased, which is convenient for manually toggling the baffle 9 to move upward or downward, providing convenience for the operation of the user.

[0046] Next, the working principle of the punching depth calibration mechanism of the punching die head will be specifically described.

[0047] As Figures 1-6 shown, after the user installs the base 1 on the equipment at the bottom of the die head, the die head is slowly moved downward to continuously approach the calibration platform 8, so that the die head contacts the top of the calibration platform 8. The die head continues to slowly press down on the calibration platform 8, causing the slide cylinder 3 to continuously contract, driving the induction flap 7 to move downward synchronously, and pushing it into the interior of the inductor 6. After triggering the induction signal of the inductor 6, the control panel 4 controls the slide cylinder 3 to stop contracting, causing the die head to stop moving. At this time, the user can read the Z-axis position data of the current die head, compare it with the standard Z-axis data, and automatically adjust the depth of the Z-axis die head according to the difference. The adjusted depth is the correct depth, thus avoiding the influence of the over-tolerance of the die depth on the subsequent processing effect of the die. If the inductor 6 is damaged and fails, the user can slowly press down the die head on the calibration platform 8 while observing the specific position where the pointer block 503 points to the scale line 505 at all times, so that the user can know the Z-axis position data of the current die head until the die head is calibrated to the correct depth to achieve the auxiliary calibration work of the die head depth.

[0048] The above has generally described the present invention in detail, but based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
