Description

Technical Field

[0001] The utility model belongs to the technical field of stamping templates, and in particular relates to a die-closing protection stamping template component. Background Art

[0002] During the stamping process, in order to ensure the safety of mold clamping and improve the stamping quality, a stop guard assembly is generally set between the lower mold plate and the upper mold plate to provide mold clamping protection. However, the problem of mold clamping stroke during the mold clamping process is ignored. When the speed of the mold clamping stroke is uneven, it is not only easy to damage the mold structure, but also more likely to damage the parts, reducing the safety of the mold structure and the stamping quality. Summary of the invention

[0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the utility model provides a mold-closing protection stamping template component, which detects the rotation speed of the rotating part driven by the side contact through the bottom convex scraping mold-closing stroke detection component, and can determine whether the mold-closing stroke is uniform and stable, thereby protecting the mold structure safety and ensuring the stamping quality.

[0004] Technical solution: To achieve the above purpose, the utility model provides a die protection stamping template assembly, comprising an upper template and a lower template. In the die closing state, the bottom convexity of the upper template extends into the clearance notch of the lower template;

[0005] It includes a mold closing stroke detection component located in the clearance gap; the mold closing stroke detection component includes a rotating part and a speed detection unit corresponding to the rotating part; when the bottom convex gradually extends into the clearance gap, the bottom convex side contacts the rotating part, driving the rotating part to rotate.

[0006] Furthermore, the mold closing stroke detection assembly also includes a bracket connected to the lower template and a rotating shaft rotatably connected to the bracket; the rotating part is a roller on the rotating shaft, and the roller is coaxially provided with a pinion; the speed detection unit on the bracket is a speed sensor, and the speed sensor is arranged toward the tooth surface of the pinion.

[0007] Furthermore, the bottom convex includes a shell and a contact block elastically arranged at a side opening of the shell by blocking and an elastomer, the shell is connected to an upper template, and the contact block contacts the elastic side of the rotating part through an elastic thrust provided by the elastomer.

[0008] Furthermore, the lower end portion of the side surface of the contact block close to the rotating part is divided into an inclined surface inclined in the opposite direction to the rotating part.

[0009] Furthermore, a limit blocking portion for laterally blocking the contact block is provided on the top of the shell.

[0010] Furthermore, when the contact block side contacts the rotating part, there is a lateral spacing between the contact block and the adjacent side surfaces of the limit blocking part, the width value of the lateral spacing is L1, the lateral width value of the inclined surface is L2, and L1 and L2 satisfy the relationship: L1﹤L2.

[0011] Beneficial effect: The utility model detects the rotation speed of the rotating part driven by the side contact through the bottom convex scraping mold closing stroke detection component, so as to obtain whether the mold closing stroke is uniform and stable. When the speed is unstable, the machine is stopped in time for maintenance to avoid impact damage to the mold structure and parts caused by non-uniform mold closing, thereby protecting the mold structure safety and ensuring the stamping quality. It is suitable for large-scale promotion and application. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Attached Figure 1 It is a schematic diagram of the structure of the cutaway template assembly in the mold closing state;

[0013] Attached Figure 2 It is a structural schematic diagram of the lower template;

[0014] Attached Figure 3 It is a structural schematic diagram of the mold closing stroke detection component. DETAILED DESCRIPTION

[0015] The utility model is further described below in conjunction with the accompanying drawings.

[0016] As attached Figure 1 As shown, a mold closing protection stamping template assembly includes an upper template 1 and a lower template 2. In the mold closing state, the bottom convex 10 of the upper template 1 extends into the clearance notch 20 of the lower template 2; it includes a mold closing stroke detection assembly 3 located in the clearance notch 20; the mold closing stroke detection assembly 3 includes a rotating part 3.1 and a speed detection unit 3.2 corresponding to the detection of the rotating part 3.1; when the bottom convex 10 gradually extends into the clearance notch 20, the bottom convex 10 contacts the rotating part 3.1 from the side, driving the rotating part 3.1 to rotate. The utility model scrapes the mold closing stroke detection assembly 3 by the bottom convex 10, and detects the speed of the rotating part 3.1 driven to rotate by the side contact, so as to determine whether the mold closing stroke is uniform and stable. When the speed is unstable, the machine is stopped in time for maintenance to avoid impact damage to the mold structure and parts under non-uniform mold closing, thereby protecting the mold structure safety and ensuring the stamping quality.

[0017] As attached Figure 2 As shown, the lower template 2 has a screw hole 21, a pin hole 22, a guide sleeve hole 23, a floating guide pin hole 24, a guide pin avoidance hole 25, a punching insert hole 26, a die 27, a floating pin hole 28, an oil drain groove 29, a limit column hole 2.1 and a pressing block hole 2.2.

[0018] As attached Figure 1 and attached Figure 3 As shown, the mold closing stroke detection assembly 3 also includes a bracket 3.3 connected to the lower mold plate 2 and a rotating shaft 3.4 rotatably connected to the bracket 3.3; the rotating part 3.1 is a roller on the rotating shaft 3.4, and the roller is coaxially provided with a pinion 3.5; the speed detection unit 3.2 on the bracket 3.3 is a speed sensor, and the speed sensor is arranged toward the tooth surface of the pinion 3.5. When the roller is rotated by side contact, the coaxial pinion 3.5 rotates synchronously, and the speed detection unit 3.2 performs speed detection in real time.

[0019] As attached Figure 1 and attached Figure 3 As shown, the bottom convex 10 includes a housing 4 and a contact block 7 elastically arranged at the side opening of the housing through a plug 5 and an elastic body 6. The housing 4 is connected to the upper mold plate 1, and the contact block 7 elastically contacts the rotating part 3.1 through the elastic thrust provided by the elastic body 6. The purpose of the elastic contact is to ensure that the contact block 7 can contact the rotating part 3.1 side when the mold is closed. Even if friction and wear occur between the contact block 7 and the rotating part 3.1 during long-term operation, the elastic force can ensure normal side contact, thereby maintaining the structure of the mold closing stroke detection component 3 and the effectiveness of the detection.

[0020] In order to make it easier for the contact block 7 and the rotating part 3.1 to enter a side contact relationship state, in the present invention, the lower end of the side surface of the contact block 7 close to the rotating part 3.1 is divided into an inclined surface 70 inclined in the opposite direction to the rotating part 3.1.

[0021] As attached Figure 1 As shown, a limit stopper 8 for laterally blocking the contact block 7 is provided on the top of the housing 4. The first aspect of the setting of the limit stopper 8 is to prevent the contact block 7 from falling off from the housing 4, and the second aspect is to prevent the contact block 7 from moving too far laterally, which causes the next side contact to be unable to be carried out. In order to prevent the above-mentioned second aspect from occurring, at the same time, when the contact block 7 is in side contact with the rotating part 3.1, the contact block 7 and the adjacent side surfaces of the limit stopper 8 have a lateral spacing 9, and the width value of the lateral spacing 9 is L1, and the lateral width value of the inclined surface 70 is L2, and L1 and L2 satisfy the relationship: L1﹤L2. Under the obstruction of the limit stopper 8, the contact block 7 will neither fall off from the housing 4 nor move too far laterally, which causes the contact block 7 to be unable to normally enter the side contact state with the rotating part 3.1.

[0022] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
