Description

Technical Field

[0001] This application relates to the field of CNC turret punch press technology, and more specifically, to a CNC turret punch press mold positioning assembly. Background Technology

[0002] CNC turret punch molds are core tooling components adapted to CNC turret punch presses. They are mainly used for efficient and precise punching, trimming, and forming of metal sheets. According to processing requirements, they can be divided into standard general-purpose molds and non-standard customized molds.

[0003] In related technologies, to solve the problems of cumbersome turret mold replacement process and the susceptibility of positioning accuracy to manual operation, for example, the patent with publication number CN218925968U provides a turret positioning device for a CNC turret punch press. This positioning component sets an annular positioning seat on the lower end face of the turret, and opens several sets of arc-shaped positioning grooves adapted to the mold on the inner side of the positioning seat. At the same time, an arc-shaped positioning block matching the positioning groove is fixed on the upper end face of the mold, and an electromagnetic adsorption component is added between the positioning seat and the mold. In use, the positioning seat is first initially aligned with the positioning groove and positioning block of the mold by rotating the turret. Then, the electromagnetic adsorption component is activated to generate an adsorption force, so that the positioning block is tightly attached to the inner wall of the positioning groove, realizing the rapid pre-positioning of the mold. Finally, the mold is radially tightened by the tightening bolts on the side of the positioning seat to complete the secondary fixation.

[0004] Although the existing technical solutions mentioned above solve the problem that the positioning accuracy of turret molds is easily affected by manual operation by setting spring-driven limit blocks to engage with the mold limit grooves, the position of the limit blocks and the size of the limit grooves are fixed designs. If the mold width changes, the original fixed position of the limit blocks will not be able to accurately align with the limit grooves of the new molds. At this time, either the new molds need to be re-processed to create new limit grooves that match the position of the limit blocks, or the limit blocks and connecting plates that are compatible with the limit grooves of the new molds need to be replaced, which increases the cost of manpower and materials and limits the applicability and flexibility of the equipment.

[0005] In view of this, we propose a positioning component for a CNC turret punch press mold. Utility Model Content

[0006] The purpose of this application is to provide a positioning component for a CNC turret punch press die, which can effectively solve the problem in the prior art that, due to the fixed position of the limit block and the size of the limit groove, the original positioning structure cannot be accurately aligned when the die width changes, requiring secondary processing of a new die or replacement of the matching limit component, resulting in increased manpower and material costs and limited applicability and flexibility of the equipment. The application achieves the effect that the positioning component can be adapted to punch press dies of different widths.

[0019] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0020] (1) This application uses an arc plate, which drives the arc plates on both sides to move synchronously towards the mold body along the radial direction of the bearing shell through the drive component, forming a stable ring-shaped clamping and fixing of the mold body. This allows the arc plate to clamp and fix molds of different widths, thus effectively solving the problem in the prior art that the original positioning structure cannot be accurately aligned when the mold width changes because the position of the limiting block and the size of the limiting groove are fixed. This requires secondary processing of a new mold or replacement of the matching limiting component, which leads to increased manpower and material costs and limited equipment applicability and flexibility. This application achieves the effect that the positioning component can be adapted to punching molds of different widths.

The control system analyzes and processes the identification information. Based on the analysis results, the adjustment component drives the mold body to rotate at a precise angle so that the bottom features of the mold body are consistent with the preset processing positioning reference, and finally achieves efficient and precise positioning of molds of different specifications.

Detailed Implementation

[0027] The present application will be further described in detail below with reference to the accompanying drawings.

[0028] Reference Figure 1 , Figure 2 and Figure 3 This application discloses a CNC turret punch mold positioning component, including a bearing shell 1, which is rotatably mounted on the top of a processing table 200. The bearing shell 1 has several through holes on its inner side, and arc-shaped plates 2 are symmetrically arranged on the inner side of each through hole for clamping the mold body 100. A driving component 3 is arranged on the outer side of the arc-shaped plates 2 for driving the arc-shaped plates 2 to clamp and fix the corresponding mold body 100. A recognition camera 4 is arranged at the bottom of the discharge port 201 and is located at the bottom of the scrap drawer 202. An adjustment component 5 is arranged at the bottom of the driving component 3 for positioning the mold body 100. The recognition camera 4 is fixedly mounted on the bottom of the processing table 200 via a fixing seat 41. A top plate is arranged on the top of the processing table 200, and a hydraulic cylinder 203 is arranged on the inner side of the top plate corresponding to the discharge port 201. The hydraulic cylinder 203 is used to press down the pressing part 101 of the mold body 100 to process the metal sheet.

[0029] First, the mold body 100 is placed inside the through hole of the bearing shell 1. At this time, the drive assembly 3 is activated so that the arc plate 2 clamps and fixes the mold body 100. After the mold body 100 is clamped, the recognition camera 4 set at the bottom of the discharge port 201 is used to identify the contour edge of the bottom of the mold body 100. The recognition camera 4 transmits the identified information to the control system. If it is necessary to adjust the position of the mold body 100 to achieve positioning, the adjustment assembly 5 is activated. The adjustment assembly 5 drives the mold body 100 to rotate until the mold body 100 reaches the preset positioning position, thus completing the positioning and fixing operation of the mold body 100.

[0030] After positioning, the waste drawer 202 is pushed into the bottom of the processing table 200 to block the bottom of the discharge port 201. The hydraulic cylinder 203 at the top of the processing table 200 is activated, and the hydraulic cylinder 203 outputs a downward driving force to press down the pressing part 101, so that the mold body 100 stamps the metal sheet placed on the top of the processing table 200. The waste generated during the processing will fall into the waste drawer 202 below through the discharge port 201 for subsequent centralized cleaning.

[0031] Reference Figure 3 and Figure 4 The drive assembly 3 includes a drive motor A31. A bidirectional screw 32 is fixedly installed at the output end of the drive motor A31. Threaded moving rings 33 are threaded on both sides of the bidirectional screw 32. A fixing plate 34 is fixedly installed on the outer side of the threaded moving rings 33. The fixing plate 34 is fixedly installed with the arc plate 2. A limit rod 35 is fixedly installed between the motor seat 311 and the bearing seat A321. The threaded moving rings 33 are slidably installed on the outer side of the limit rod 35.

[0032] The mold body 100 is placed inside the through hole of the bearing shell 1. The drive assembly 3 is started, and the drive motor A31 outputs power to drive the bidirectional screw 32 to rotate. The bidirectional screw 32 is stably supported by the bearing seat A321. When the bidirectional screw 32 rotates, the threaded moving ring 33 is threadedly engaged with the bidirectional screw 32, so that the threaded moving ring 33 will move closer to each other synchronously along the axial direction of the bidirectional screw 32. Then, the fixed plate 34 pushes the arc plate 2 to clamp and fix the mold body 100. The centers of the two arc plates 2 are concentric with the center of the through hole of the bearing shell 1, so that the two arc plates 2 can initially position the mold body 100.

[0033] Reference Figure 3 and Figure 4 The adjustment assembly 5 includes a drive motor B51, a gear 52 fixedly mounted on the output end of the drive motor B51, a gear ring 53 meshing with the outer side of the gear 52, the gear ring 53 being used to drive the arc plate 2 to rotate, a base plate 11 being provided at the bottom of the bearing shell 1, the drive motor B51 being fixedly mounted on the top of the base plate 11, the gear ring 53 being rotatably mounted on the top of the base plate 11 via a bearing seat B531, the bottom of the drive motor A31 being fixedly mounted on the top of the gear ring 53 via a motor seat 311, a bidirectional screw 32 being rotatably mounted on the inner side of the bearing seat A321, the bearing seat A321 being fixedly mounted on the top of the gear ring 53, a spring 21 being provided on the outer side of the arc plate 2, a connecting plate 22 being fixedly mounted on the outer side of the spring 21, and the connecting plate 22 being fixedly mounted on the inner side of the gear ring 53.

[0034] If the position of the mold body 100 needs to be adjusted to achieve positioning, start the drive motor B51 to drive the gear 52 to rotate. The gear 52 meshes with the gear ring 53 for transmission. The gear ring 53 is stably supported by the bearing seat B531, and then the mold body 100 rotates until the mold body 100 reaches the preset positioning position.

[0035] In summary, when using the CNC turret punch mold positioning assembly disclosed in this application embodiment, firstly, the mold body 100 is placed inside the through hole of the bearing shell 1, the drive assembly 3 is started, and the drive motor A31 outputs power to drive the bidirectional screw 32 to rotate. The bidirectional screw 32 is stably supported by the bearing seat A321. When the bidirectional screw 32 rotates, the threaded moving ring 33 is threadedly engaged with the bidirectional screw 32, so that the threaded moving ring 33 will synchronously move closer to each other along the axial direction of the bidirectional screw 32. Then, the fixed plate 34 pushes the arc plate 2 to clamp and fix the mold body 100. The centers of the two arc plates 2 are concentric with the center of the through hole of the bearing shell 1, so that the two arc plates 2 can initially position the mold body 100.

[0036] After the mold body 100 is clamped, the identification camera 4 set at the bottom of the discharge port 201 is used to identify the contour edge of the bottom of the mold body 100. The identification camera 4 transmits the identified information to the control system. If the position of the mold body 100 needs to be adjusted to achieve positioning, the drive motor B51 is started, which drives the gear 52 to rotate. The gear 52 meshes with the gear ring 53 for transmission. The gear ring 53 is stably supported by the bearing seat B531, and then the mold body 100 rotates until the mold body 100 reaches the preset positioning position.

[0037] After positioning, the waste drawer 202 is pushed into the bottom of the processing table 200 to block the bottom of the discharge port 201. The hydraulic cylinder 203 at the top of the processing table 200 is activated, and the hydraulic cylinder 203 outputs a downward driving force to press down the pressing part 101, so that the mold body 100 stamps the metal sheet placed on the top of the processing table 200. The waste generated during the processing will fall into the waste drawer 202 below through the discharge port 201 for subsequent centralized cleaning.
