Description

Technical Field

[0001] The utility model belongs to the technical field of stamping templates, and particularly relates to a stamping template assembly for monitoring the steady state of mold closing. Background Technique

[0002] During the stamping production process, the existing upper template uses a guiding component for guiding so that it can cooperate with the lower template to achieve better mold closing for stamping. Affected by the failure of the guiding component or the installation error of the template, the upper and lower templates are prone to the error inclination situation of non-facing mold closing. Due to the small inclination degree, it is difficult to discover and solve from the visual aspect, which brings trouble to the template adjustment and reduces the quality of mold closing processing. Summary of the Invention

[0003] Purpose of the Invention: In order to overcome the deficiencies existing in the prior art, the utility model provides a stamping template assembly for monitoring the steady state of mold closing. Through a double-point touch-pressure mold closing steady state monitoring structure formed by a pair of push-button pressure monitors during mold closing, the steady state of mold closing can be judged according to the differential pressure monitoring of the two push-button pressure monitors, and the quality of mold closing for stamping can be improved.

[0004] Technical Solution: To achieve the above purpose, a stamping template assembly for monitoring the steady state of mold closing of the utility model includes an upper template and a lower template. A contact head is arranged at the bottom of the upper template, and a push-button pressure monitor is embedded in the lower template. The contact head is arranged to touch-press the push-button pressure monitor; the push-button pressure monitors are a pair symmetrically distributed on the lower template. In the mold closing state, the contact head correspondingly touches and presses the push-button pressure monitor to form a double-point touch-pressure mold closing steady state monitoring structure.

[0005] Further, one of the push-button pressure monitors is located on the concave die side of the lower template, and the other push-button pressure monitor is located on the insert block hole side of the lower template. The contact head and the push-button pressure monitor are arranged in a one-to-one correspondence up and down.

[0006] Further, an embedding groove corresponding to the push-button pressure monitor is opened on the lower template, and the push-button pressure monitor is embedded in the embedding groove.

[0007] Further, the push-button pressure monitor includes a housing, a piston, a push rod, and a gas pressure detection device; the housing is installed in the embedding groove through a housing seat; the push rod is hermetically slidably matched with the housing through the piston; the gas pressure detection device penetrates through the housing seat and is installed so that its detection probe extends into the inner bottom of the housing; the movement state of the push rod includes a downward movement state of being touched and pressed by the contact head and an upward movement state of pushing the piston back by the gas pressure in the housing when the touch pressure is released. The gas pressure change is detected by the gas pressure detection device when the push rod is in the upward movement state and the downward movement state.

[0008] Further, a protective ring is provided at the inner bottom of the outer shell, which encloses and is higher than the detection probe of the air pressure detection device.

[0009] Further, mounting holes corresponding to the air pressure detection device and wire routing gaps for the air pressure detection device to route wires are provided at the bottom of the lower template.

[0010] Beneficial effects: The utility model forms a double-point touch pressure closing die steady state monitoring structure by a pair of push-button pressure monitors during the closing die process. It can judge the steady state of the closing die according to the difference in pressure monitoring of the two push-button pressure monitors, so as to adjust the inclination of the template, eliminate the steady state hidden danger existing in the stamping die, and improve the closing die stamping quality, which is suitable for large-scale popularization and application. Description of the Drawings

[0011] Appendix Figure 1 is a schematic structural diagram of the lower template of the utility model;

[0012] Appendix Figure 2 is a partially sectional schematic structural diagram of the stamping template assembly of the utility model. Detailed Embodiments

[0013] The following further describes the utility model with reference to the drawings.

[0014] As shown in Appendix Figure 1 and Appendix Figure 2 A stamping template assembly for closing die steady state monitoring includes an upper template 1 and a lower template 2. A contact 3 is provided at the bottom of the upper template 1, and a push-button pressure monitor 4 is embedded in the lower template 2. The contact 3 is arranged to touch and press the push-button pressure monitor 4. The push-button pressure monitors 4 are a pair symmetrically distributed on the lower template 2. In the closed die state, the contact 3 correspondingly touches and presses the push-button pressure monitors 4 to form a double-point touch pressure closing die steady state monitoring structure. The utility model forms a double-point touch pressure closing die steady state monitoring structure by a pair of push-button pressure monitors 4 during the closing die process. It can judge the steady state of the closing die according to the difference in pressure monitoring of the two push-button pressure monitors 4, so as to adjust the inclination of the template, eliminate the steady state hidden danger existing in the stamping die, and improve the closing die stamping quality.

[0015] As shown in Appendix Figure 1As shown, affected by the installation operations of the mold insert and the female die, it will affect whether the template is installed horizontally, and there is a relatively large distance between the insert and the female die. To improve the monitoring intuitiveness, one of the push-type pressure monitors 4 is located on the side of the female die 21 of the lower template 2, and the other push-type pressure monitor 4 is located on the side of the insert hole 22 of the lower template 2. The contact heads 3 are arranged in one-to-one correspondence with the push-type pressure monitors 4 up and down. If the template tilts, the difference in the pressure values measured by the two push-type pressure monitors 4 will be relatively large, so that it can be more intuitively concluded that the mold closing is in an unsteady state.

[0016] As shown in the Figure 1 attachment, an embedding groove 23 corresponding to the push-type pressure monitor 4 is formed on the lower template 2, and the push-type pressure monitor 4 is embedded in the embedding groove 23.

[0017] More specifically, as shown in the Figure 2 attachment, the push-type pressure monitor 4 includes a housing 41, a piston 42, a push rod 43, and a pneumatic detection device 44. The housing 41 is installed in the embedding groove 23 through a housing seat 41a and then fixed by bolts 41b. The push rod 43 is in sealed sliding fit with the housing 41 through the piston 42. The pneumatic detection device 44 is installed through the housing seat 41a so that its detection probe extends into the inner bottom of the housing 41. The motion states of the push rod 43 include a downward movement state of being touched and pressed by the contact head 3 and an upward movement state of pushing the piston 42 back by the air pressure in the housing 41 when the touch and press are released. The push rod 43 detects the air pressure change through the pneumatic detection device 44 in the upward movement state and the downward movement state. The principle of the present utility model for monitoring the steady state of mold closing is as follows: When stamping and closing the mold, the upper template 1 drives the contact head 3 to move downward synchronously. The contact head 3 touches and presses the push rod 43, causing the push rod 43 to drive the piston 42 to move downward to compress the gas in the housing 41. The pneumatic detection devices 44 of the two push-type pressure monitors 4 perform air pressure detection. The pneumatic detection devices 44 are connected to the system terminal, and the system terminal compares and analyzes the air pressure detection values detected by the two pneumatic detection devices 44. When there is a difference in the comparison of the air pressure detection values, it indicates that the mold closing is in an unsteady state. An alarm can be given through the alarm built in the system terminal, and at the same time, the stamping processing operation can be controlled to stop by the system terminal, and the maintenance personnel can conduct fault troubleshooting. When there is no difference in the comparison of the air pressure detection values, it indicates that the mold closing is in a steady state. Among them, the pneumatic detection device 44 is preferably a pneumatic sensor.

[0018] To prevent over-travel during mold closing, that is, the stroke of the contact head 3 touching and pressing the push rod 43 is too large, causing the piston 42 to damage the pneumatic detection device 44. In the present utility model, as shown in the Figure 2 attachment, a protective ring 45 that surrounds and is higher than the detection probe of the pneumatic detection device 44 is arranged at the inner bottom of the housing 41.

[0019] As attached Figure 2 As shown, the bottom of the lower template 2 is provided with a mounting hole 24 corresponding to the air pressure detection device 44 and a wiring notch 25 for the air pressure detection device 44 to route wires.

[0020] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
