Abstract
Description
Technical Field
[0001] This utility model relates to the field of press technology, and in particular to an open fixed table press. Background Technology
[0002] The open-type fixed-table press uses the crankshaft and connecting rod as its working mechanism. It is a general-purpose press for sheet metal stamping and can be used for cutting, punching, blanking, forming, bending, shallow drawing, forming and other cold stamping processes.
[0003] When steel strip is used as raw material for stamping products, it is fed into the press from one side. After being stamped by the press, the parts are discharged from below the worktable, and the waste is discharged from the right side of the press. When the steel strip is fed into the press, it lacks auxiliary support, which can easily cause the steel strip to bend and the stamped part to curl upwards, thus affecting the stamping quality of the parts.
[0004] Therefore, this application provides an open-type fixed-table press to meet the requirements. Utility Model Content
[0005] The purpose of this application is to provide an open-type fixed-table press, which aims to solve the problem of insufficient auxiliary support for the steel strip, thereby affecting the stamping quality of parts.
[0006] To achieve the above objectives, this application provides the following technical solution: an open-type fixed-table press, comprising a press body and a worktable, wherein the worktable is mounted on the press body, and the worktable cooperates with the press body to complete the stamping process of parts;
[0007] The worktable is provided with hinge seats on both the left and right sides. A rotating rod is rotatably connected to the hinge seat. A mounting frame is also provided on the rotating rod. A support roller is provided on the mounting frame. The support roller is used to support the steel strip to be processed. By setting mounting frames on both sides of the worktable and cooperating with the rotating rod and support roller, the mounting frame can be rotated so that the support roller provides auxiliary support for the steel strip, ensuring that the steel strip is horizontal, which facilitates the subsequent stamping of parts and thus improves product quality.
[0008] The hinged base is also equipped with a limiting mechanism and a locking mechanism for the rotating rod.
[0009] Preferably, both ends of the rotating rod protrude from the hinge seat, and the two ends of the rotating rod correspond to the positions of the limiting mechanism and the locking mechanism, respectively.
[0010] Preferably, the locking mechanism includes a threaded section and a nut. The threaded section is provided on the right end of the rotating rod, and the nut is engaged on the threaded section. The rotating rod is limited by the friction between the nut and the hinge seat. A limiting mechanism is provided at one end of the rotating rod so that the operator can limit the rotation of the rotating rod and the mounting bracket in time when adjusting the rotation angle. In conjunction with the locking mechanism, the tilt angle between the mounting bracket and the worktable is fixed, increasing the adaptability of the equipment.
[0011] Preferably, the limiting mechanism includes a limiting sleeve and a spring. The limiting sleeve is slidably connected to the hinge seat, and the spring is provided between the limiting sleeve and the hinge seat. The limiting sleeve is positioned corresponding to the left end of the rotating rod. A keyway is provided on the left end of the rotating rod, and a spline adapted to the size of the keyway is provided on the inner wall of the limiting sleeve.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Example 1: Reference Figure 1-4 An open-type fixed-table press is shown, including a press body 1 and a worktable 2. The worktable 2 is installed on the press body 1, and the worktable 2 cooperates with the press body 1 to complete the stamping process of the parts.
[0023] The workbench 2 is provided with hinge seats 6 on both the left and right sides. A rotating rod 5 is rotatably connected to the hinge seat 6. A mounting frame 3 is also provided on the rotating rod 5. A support roller 4 is provided on the mounting frame 3. The support roller 4 is used to support the steel strip to be processed.
[0024] The mounting frame 3 includes vertical rods 31 and horizontal rods 32. There are two sets of vertical rods 31, which are symmetrically arranged on the rotating rod 5. The horizontal rods 32 are also provided between the two sets of vertical rods 31. The horizontal rods 32 are used to support and fix the two sets of vertical rods 31. One end of the two sets of vertical rods 31 is connected to the rotating rod 5, and the other end is rotatably connected to the support roller 4. The support roller 4 is a rubber roller, which plays a supporting role for the steel strip.
[0025] The hinge seat 6 is also provided with a limiting mechanism and a locking mechanism for the rotating rod 5.
[0026] Both ends of the rotating rod 5 protrude from the hinge seat 6, and the two ends of the rotating rod 5 correspond to the positions of the limiting mechanism and the locking mechanism, respectively.
[0027] The locking mechanism includes a threaded section 9 and a nut 8. The threaded section 9 is provided on the right end of the rotating rod 5, and the nut 8 is engaged on the threaded section 9. The rotating rod 5 is limited by the friction between the nut 8 and the hinge seat 6.
[0028] The limiting mechanism includes a limiting sleeve 7 and a spring 10. The limiting sleeve 7 is slidably connected to the hinge seat 6. The limiting sleeve 7 can only slide along the axial direction of the rotating rod 5 and cannot rotate. The spring 10 is provided between the limiting sleeve 7 and the hinge seat 6. The limiting sleeve 7 corresponds to the left end of the rotating rod 5. A keyway 11 is provided on the left end of the rotating rod 5. A spline 12 that matches the size of the keyway 11 is provided on the inner wall of the limiting sleeve 7. The spline 12 cooperates with the keyway 11 to limit the rotation rod 5 and the mounting bracket 3.
[0029] The working principle of this utility model is as follows: Before use, adjust the angle between the mounting bracket 3 and the worktable 2, pull the limiting sleeve 7 to move it away from the rotating rod 5, the spring 10 is stretched, the spline 12 on the limiting sleeve 7 separates from the keyway 11 on the rotating rod 5, releasing the limitation on the rotating rod 5. Rotate the mounting bracket 3, which simultaneously drives the rotating rod 5 to rotate on the hinge seat 6, adjusting the angle of the mounting bracket 3. After adjustment, release the limiting sleeve 7, and under the elastic force of the spring 10, the limiting sleeve 7 returns to its original position, and the spline 12 is embedded in the keyway 11. The rotating rod 5 is limited, thus temporarily limiting the mounting frame 3. The nut 8 is rotated, and through its meshing relationship with the threaded section 9, the nut 8 contacts the hinge seat 6. Under the action of friction between the two, the mounting frame 3 is locked and limited, completing the equipment adjustment. One end of the steel strip is placed on the worktable 2 through the support roller 4, and the press body 1 is started for stamping. Under the support of the support roller 4, the steel strip remains horizontal, preventing it from warping at the stamping point and affecting the stamping accuracy of the parts.
