Description

Technical Field

[0001] This utility model relates to the field of metal mold stamping production technology, and more specifically, it relates to an automatic collection device for metal mold stamping parts. Background Technology

[0002] In the metal mold stamping production process, the automatic collection and sorting of stamped parts is an important link to improve production efficiency and product quality. Especially in high-frequency stamping and continuous production modes, the collection device needs to work closely with the stamping equipment to achieve precise positioning and stable collection.

[0003] In traditional metal mold stamping production lines, the collection device usually adopts a simple mechanical clamping or bolt fixing method. This fixing method lacks convenience and reliability when facing the need for frequent collection box replacement and position adjustment. Operators need to use professional tools to perform complex disassembly and installation operations, which is not only cumbersome but also time-consuming.

[0004] In production environments with multiple product specifications and rapid model changes, traditional fixing methods often cannot quickly respond to different collection needs, resulting in prolonged equipment downtime and reduced production efficiency. At the same time, due to the simple design of the fixing structure, it is prone to loosening or displacement when subjected to stamping vibration and the weight of the collection box, affecting the working accuracy of the collection device and the accuracy of stamping parts collection.

The insertion rod is inserted into the fixing hole and the insertion hole to achieve precise docking between the collecting device and the support frame, ensuring the accuracy of the fixed position and the reliability of the connection.

[0008] The present invention is further configured such that all of the multiple sets of rotating shafts are damping rotating shafts, providing damping control for the rotation of the locking block, preventing the locking block from rotating accidentally and ensuring the smoothness of locking and unlocking actions.

[0009] The present invention is further configured such that a guide block is fixedly provided on the inner side of the limiting sleeve, and a guide groove is provided on the outer wall of the fixed sleeve. Multiple sets of the guide block and the guide groove are provided and slidably connected to ensure the linear sliding and precise positioning of the limiting sleeve, and to prevent the limiting sleeve from deviating and jamming during the movement process.

[0010] The present invention is further configured such that a tension spring is connected to the outer wall of the rotating sleeve, and multiple sets of tension springs are provided, each with a connecting ring at its bottom end. An arc-shaped block is fixed on the bottom surface of each set of connecting rings, and an annular groove is opened on the top surface of the rotating sleeve. The multiple sets of arc-shaped blocks slide within the annular groove, providing automatic reset force for the limiting sleeve and smooth rotation operation of the rotating sleeve, ensuring reliable reset of the locking system and convenient operation.

[0011] The present invention is further configured such that a positioning sleeve is fixedly provided on the top surface of the rotating sleeve, and a sliding hole is provided on the inner wall of the positioning sleeve. Multiple sets of sliding holes are provided, and each set of sliding holes is connected to a push spring on its inner side.

[0014] (III) Beneficial Effects Compared with the prior art, this utility model provides an automatic collection device for stamped parts of hardware molds, which has the following beneficial effects: 1. This device effectively solves the problems of cumbersome operation and slow response of traditional collection device fixing methods through the insertion and engagement of the insertion rod and the fixed sleeve, as well as the rotation and locking mechanism of the locking block and the slot. The operator only needs to insert the insertion rod into place and push the limiting sleeve to quickly fix the collection box by rotating the locking block. There is no need to use professional tools for complicated bolt disassembly and assembly operations. The distributed locking design of multiple sets of locking blocks provides reliable clamping force and load-bearing stability. The damping shaft ensures the smooth rotation and precise positioning of the locking block, which significantly shortens the operation time for replacing and adjusting the position of the collection box, improves the equipment utilization rate and production efficiency in the production of multi-specification products and rapid changeover environments, and effectively reduces equipment downtime and the frequency of manual intervention.

[0015] 2. This device employs a locking system combining a limiting sleeve and a tension spring. Through the action of elastic force, it reliably maintains the position of the clamping block and provides vibration protection, effectively overcoming the problems of easy loosening and unstable load-bearing in traditional mechanical clamping methods. The sliding connection between the guide block and the guide groove ensures the straightness and positioning accuracy of the limiting sleeve movement. The elastic design of multiple tension springs provides continuous preload to resist the effects of stamping vibration and thermal expansion and contraction. The cooperation between the arc-shaped block and the annular groove enhances the smoothness of rotation operation and the stability of force transmission. The sliding connection between the bottom surface of the arc-shaped clamping block and the mounting groove increases the contact area and clamping uniformity, significantly improving the reliability and durability of the fixing system under high-intensity stamping conditions, ensuring the long-term stability of the collection box position and the accuracy of stamped parts collection.

[0016] 3. The quick unlocking system of this device, which combines the rotating sleeve and the limiting block, achieves one-button unlocking by switching the limiting block between the limiting groove and the unlocking hole. This effectively solves the problems of complex unlocking and safety risks associated with traditional fixing methods. The automatic positioning function of the positioning sleeve and the push spring ensures the precise positioning of the rotating sleeve and the reliable maintenance of the operating state. The entire disassembly and assembly process only requires rotating the rotating sleeve to complete multi-point synchronous unlocking, avoiding the safety hazards of multi-step operations and accidental loosening. The automatic reset mechanism reduces the impact of operational errors and human factors, significantly improving the safety and convenience of maintenance operations, reducing the technical requirements and labor intensity of operators, and meeting the high reliability and rapid response technical requirements of modern hardware stamping production for collection devices.

Then, the fixing sleeve 8 is inserted into the top of the insertion rod 7. The insertion rod 7 pushes multiple sets of locking blocks 11 to rotate along the rotating shaft 10 and pushes the locking blocks 11 to make way for the insertion rod 7. Then, the limiting sleeve 13 pushes the multiple sets of locking blocks 11 to rotate and engage in the slot 12. At the same time, the limiting sleeve 13 stretches multiple sets of tension springs 23.

The insert rod 7 pushes the multiple sets of locking blocks 11 to rotate along the rotating shaft 10 and disengage from the locking groove 12, releasing the fixation on the fixing plate 6.

[0032] In summary, during the use or operation of the overall equipment: when it is necessary to fix the collection box 5, align the insertion hole 20 with the fixing hole 19 and insert it into the insertion rod 7. Then, insert the fixing sleeve 8 into the top of the insertion rod 7.
