Description

Technical Field

[0001] The utility model relates to the technical field of presses, in particular to a press with a positioning structure. Background Art

[0002] A press is a general-purpose press with a sophisticated structure. It has the characteristics of wide application and high production efficiency. The press can be widely used in processes such as cutting, punching, blanking, bending, riveting and forming. It applies strong pressure to the metal blank to cause plastic deformation and fracture of the metal to be processed into parts. In the production process of casting molding materials, a press is needed to plasticize the material.

[0003] For example, a press for producing molding materials for casting disclosed in publication number CN218361534U drives the first clamping member and the second clamping member through the third telescopic drive member to retract and clamp the material. This method of clamping is accurate and stable. The retraction of the second telescopic drive member causes the material to move horizontally to one side, thereby completing the clamping work.

[0004] However, when the positioning structure is in use, it can only clamp and fix one side of the material. Such fixation not only easily causes the material to be displaced due to collision, resulting in poor positioning effect, but also this clamping method will cause a part of the material to not be punched, thereby reducing the use effect of the device. In view of this, we propose a press with a positioning structure. Utility Model Content

[0005] The purpose of the utility model is to provide a press machine with a positioning structure to solve the problems raised in the above background technology.

[0014] Compared with the prior art, the utility model provides a press with a positioning structure, which has the following beneficial effects:

[0015] 1. The press machine with a positioning structure is provided with a positioning structure so as to facilitate positioning and fixing of two sides or four sides of the workpiece. When in use, the user places the workpiece on the upper end of the base, and then the user can start the motor to drive the screw to rotate, and the rotation of the screw drives the sleeve on the surface to move, and the movement of the sleeve drives the connecting rod of the side wall to move, and the movement of the connecting rod drives the four groups of positioning plates to move to position and fix the two sides or four sides of the workpiece, and the positioning structure will not cause a part of the material to be unable to be punched, thereby improving the use effect of the device.

[0016] 2. The press machine with a positioning structure is provided with a cleaning structure so as to facilitate automatic cleaning of the material and the base surface after pressure processing. When the workpiece is processed, the positioning plate moves outward, and the positioning plate drives the pressure rod to move. The movement of the pressure rod drives the piston plate at its end to move inward. At this time, the movement of the piston plate will squeeze the air in the cylinder into the ventilation pipe, and then the gas will be ejected from the air spray frame to automatically clean the material and the positioning frame surface, thereby preventing the waste chips generated by the processing from falling on the material and the positioning frame surface.

[0023] Specifically, the positioning structure 3 of the technical solution of the utility model includes: a positioning frame 31, a screw rod 32, a sleeve 33, a motor 34, a slide groove 35, a positioning plate 36, and a connecting rod 37.

[0024] In one embodiment of the utility model, a positioning structure 3 is provided to facilitate positioning and fixing of two or four sides of a workpiece. When in use, the user places the workpiece in the middle of the upper end of the base 1, and then the user can start the motor 34 to work. The model of the motor 34 is HG-JR353BK. The motor 34 provides power for the rotation of the screw 32. The output shaft of the motor 34 drives the screw 32 fixedly connected thereto to rotate. The rotation of the screw 32 drives the sleeve 33 threadedly connected to its surface to move. The movement of the sleeve 33 drives the connecting rod 37 of its side wall to move. The movement of the connecting rod 37 drives the four groups of positioning plates 36 hinged thereto to move. At this time, the positioning plates 36 move in a directional manner inside the slide groove 35. The two or four sides of the workpiece are positioned and fixed by the movement of the four groups of positioning plates 36. Moreover, since the height of the positioning plates 36 located outside the positioning frame 31 is relatively short, a part of the material will not be unable to be punched, thereby improving the use effect of the device.

[0025] When the connecting rod 37 moves and drives the four groups of positioning plates 36 hinged thereto to move, the movement of one group of positioning plates 36 will also drive the pressure rod 45 of its side wall to move, and the movement of the pressure rod 45 drives the piston plate 46 at its end to move outward. At this time, the piston plate 46 moves so that the intake pipe 44 can replenish gas inside the cylinder 41. A first one-way valve 10 and a second one-way valve 11 are respectively provided on the surfaces of the ventilation pipe 42 and the intake pipe 44. The first one-way valve 10 allows the ventilation pipe 42 to only discharge gas to the outside, and the second one-way valve 11 allows the intake pipe 44 to only discharge gas to the outside. Gas can be added into the cylinder 41, and when the workpiece is processed, the user can control the positioning plate 36 in the positioning structure 3 to move outward and return to the original position. At this time, the positioning plate 36 will drive the pressure rod 45 on its side wall to move, and the movement of the pressure rod 45 will drive the piston plate 46 at its end to move inward. At this time, the movement of the piston plate 46 will squeeze the air in the cylinder 41 into the ventilation pipe 42, and then the gas will be ejected from the air spray frame 43 to automatically clean the surface of the material and the positioning frame 31, thereby preventing the waste chips generated by the processing from falling on the surface of the material and the positioning frame 31.

[0026] And when the positioning plate 36 moves, it will drive the fixing bar 7 of its side wall to move, and the movement of the fixing bar 7 will drive the tooth plate 8 of its side wall to move, and the movement of the tooth plate 8 will drive the rotating gear 9 meshing with it to rotate, and the rotation of the rotating gear 9 will drive the ventilation pipe 42 inside it to rotate a certain angle, so that when cleaning, the air spray frame 43 can clean from one side of the positioning frame 31 to the other side of the positioning frame 31, further improving the use effect of the device.

[0027] Please continue reading Figure 1-Figure 4The cleaning structure 4 includes a cylinder body 41 fixedly mounted on the side wall of the bracket 2, one end of a ventilation pipe 42 is fixedly mounted on the side wall of the cylinder body 41, and an air jet frame 43 is fixedly mounted on the other end of the ventilation pipe 42.

A rotating gear 9 is fixedly mounted on the surface of the ventilation pipe 42, and a first one-way valve 10 and a second one-way valve 11 are respectively provided on the surfaces of the ventilation pipe 42 and the intake pipe 44. The intake pipe 44 and the ventilation pipe 42 are in a connected state with the inside of the cylinder body 41, and a notch adapted to the moving trajectory of the toothed plate 8 is opened on the side wall of the bracket 2, and the rotating gear 9 and the toothed plate 8 are in a meshing state.

[0028] During operation, the user places the workpiece on the middle of the upper end of the base 1, and then starts the motor 34 to drive the screw 32 to rotate, the rotation of the screw 32 drives the sleeve 33 to move, the movement of the sleeve 33 drives the connecting rod 37 to move, the movement of the connecting rod 37 drives the four groups of positioning plates 36 hinged thereto to move, and the two sides or four sides of the workpiece are positioned and fixed by the movement of the four groups of positioning plates 36, and then the electric push rod 5 is started to drive the pressing plate 6 to move downward for processing.
