Description

Technical Field

[0001] The utility model relates to the technical field of servo presses, and particularly to a raw material position correction structure for servo press feeding. Background Art

[0002] A servo press is a high-precision and high-efficiency metal sheet processing equipment driven by a servo motor, which can realize precise stamping, forming, cutting and other operations, and is an important equipment indispensable in modern manufacturing.

[0003] A circular plate is a commonly used processing raw material. In actual production, in order to improve production efficiency, the press generally designs a supporting feeding mechanism to achieve continuous feeding, which greatly improves the working efficiency of the press. However, during the feeding process, the raw material often shifts in position due to vibration or collision, thus affecting the accuracy of the normal pressure of the press. This requires the use of a correction and positioning structure to cooperate in positioning the feeding position. The existing correction method is generally to fix a concave die corresponding to the outer shape of the raw material in the stamping area to achieve precise limit. However, different diameter circular plates require different limit concave dies, and the installation, disassembly and replacement are also relatively troublesome. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is that the size of the existing die for positioning circular plates is fixed and it is inconvenient to adjust and correct correspondingly according to the change of the diameter of the raw material.

[0005] To solve the above technical problem, the utility model provides the following technical solution: A raw material position correction structure for servo press feeding proposed by the utility model includes an installation positioning block, a clamping structure and a driving structure installed on the installation positioning block. The clamping structure includes an arc-shaped positioning block and clamping components hinged on both sides of the arc-shaped positioning block. The arc-shaped positioning block is arranged on the side wall of the installation positioning block. The clamping components include clamping jaws, return springs and driving bumps. The clamping jaws are arranged in an arc structure. One end of the clamping jaws is hinged on both side walls of the arc-shaped positioning block. The return springs are arranged on the side wall of the arc-shaped positioning block and the other end is connected with the clamping jaws. The driving bumps are arranged on the outer wall of the clamping jaws.

[0006] Preferred Technical Solution 1: The driving structure includes a driving chamber, a driving motor, a threaded block, a driving screw rod, and a transmission rod. The driving chamber is provided on the other side wall of the installation positioning block. The two ends of the driving screw rod are rotatably provided on the opposite side walls inside the driving chamber. The driving motor is provided on the outer wall of the driving chamber and its power output shaft is connected to the driving screw rod. There are two sets of thread groups with opposite thread directions on the driving screw rod. There are two sets of threaded blocks, and the two sets of threaded blocks are threadedly connected to the two sets of thread groups with opposite thread directions. A limiting sliding groove is provided on the side wall of the driving chamber. One end of the transmission rod is provided on the threaded block, and the other end of the transmission rod penetrates and slides in the limiting sliding groove. A guiding roller is provided at one end of the transmission rod, and a guiding sliding groove corresponding to the guiding roller is provided on the driving convex block.

[0007] Preferred Technical Solution 2: An adjusting screw rod penetrates through and is threadedly connected to the clamping jaw. A guiding rod also penetrates and slides through the clamping jaw. A pressing block is provided on the guiding rod, and one end of the adjusting screw rod is rotatably connected to the pressing block.

[0008] Preferred Technical Solution 3: Two positioning pins are provided at the bottom of the installation positioning block. An installation bolt is also threadedly connected to the installation positioning block.

[0009] Preferred Technical Solution 4: An uneven anti-slip pad is also provided on the pressing block.

[0010] For a raw material position correction structure for a servo punch press feeding proposed by the present utility model, the beneficial effects obtained by adopting the above structure are as follows:

[0011] (1) It is installed on the stamping table through the installation positioning block. The driving motor, threaded block, driving screw rod, and transmission rod cooperate to drive the two clamping jaws to perform auxiliary positioning on the circular plate part.
