Technical Field

[0001] This utility model relates to the field of press technology, and in particular to a linkage-type manual press. Background Technology

[0002] In small manufacturing workshops, hardware processing workshops, and parts repair scenarios, there is a wide demand for press-fitting of parts such as bearings, bushings, and small components. These operations are often characterized by "small batches and multiple specifications," requiring the press to have sufficient structural stability to ensure press-fitting accuracy, and also requiring it to be flexible enough to adapt to the press-fitting needs of parts of different sizes and types.

[0003] Existing manual presses suffer from poor overall stability during pressing due to their simple structure and lack of reinforcement design. This leads to pressure head misalignment, resulting in misaligned parts and low precision. Insufficient and uneven pressing pressure also causes parts to be loosely pressed, leading to loosening and detachment. The fixed pressing fixtures cannot be replaced, limiting their use to pressing only single products. When dealing with parts of various specifications, different presses must be used, increasing equipment costs and operating time, resulting in low efficiency. Furthermore, the low height adjustment precision makes it difficult to accurately adapt to products of different heights, further affecting the pressing quality. Utility Model Content

[0004] The purpose of this invention is to solve the problems of poor overall stability, easy displacement of the press head, misalignment of parts, and low precision in the press-fitting process of existing presses, and to propose a linkage-type manual press.

Because the lead screw 7 is threadedly connected to the movable seat 11 and the movable seat 11 is located in the square groove 6, it cannot rotate with the lead screw 7. When the lead screw 7 rotates, the movable seat 11 slides up and down along the square groove 6, adjusting the pressure head 12 to a height suitable for the product to be pressed. Then, place the product to be pressed on the placement plate 19 on the inner side wall of the bottom of the L-shaped base 5. Then, pull down the elbow lever 15. The elbow lever 15 drives the swing arm seat 14 to rotate around the pin near the top inside the movable seat 11. The bottom of the swing arm seat 14 pushes the hinge plate 13 through the pin, and the hinge... Plate 13 drives the pressure head 12 to move downward within the movable seat 11. The pressure block 17 embedded at the bottom of the pressure head 12 then drives the pressing fixture 18 to press down synchronously, performing pressing operations on the product placed on plate 19. The triangular plates 4 on the four sides of the vertical column 1 and the bottom plate 2 together enhance the overall structural stability of the equipment and prevent shaking during pressing. The round head 16 at one end of the elbow 15 improves operational safety. The pressure plate 20 of the movable seat 11 can help fix the position of the movable seat 11 to ensure pressing accuracy. After pressing is completed, the elbow 15 is pulled upward to drive the pressure head 12 and the pressing fixture 18 to move upward and remove the pressed product. If different types of products need to be pressed, the pressing fixture 18 at the bottom of the pressure head 12 can be replaced.
