Abstract
Description
Technical Field
[0001] This utility model relates to the field of manual press technology, and in particular to a labor-saving manual press. Background Technology
[0002] A press is a machine used to form or assemble industrial products by pressure. It has a wide range of applications and is mainly divided into two types: automatic press and manual press. Automatic presses are generally driven by hydraulic cylinders, so they are also called oil presses. They can meet the pressing needs of large tonnage, but the equipment investment is large. For situations where the pressure requirement is not high, manual presses are mostly selected. For example, the pressing of oil pipe parts is generally done by manual press or by hand.
[0003] In actual use, the following shortcomings were found in this device:
[0004] When adjusting the height of the press head, it is usually done by manually driving the operating handle. The automatic adjustment of the operating handle is not very precise, and the switching between manual and automatic operation of the operating handle is not very effective, which reduces the effort-saving effect for the operator when driving the press.
[0005] Therefore, this application provides a labor-saving manual press to meet the requirements. Utility Model Content
[0006] The purpose of this utility model is to solve the problems existing in the above-mentioned background technology and to propose a labor-saving manual press.
[0007] The technical problem to be solved by this utility model is to provide a labor-saving manual press to solve the problems of low automatic adjustment of the operating handle angle and poor performance in driving the operating handle and switching between manual and automatic operation.
[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0009] A labor-saving manual press includes a press body: a fixed rod is fixedly connected to the outer wall of the press body; a lifting block is slidably connected to the outer wall of the fixed rod; an operating shaft is rotatably connected to the outer wall of the lifting block; an electric push rod is fixedly connected to the outer wall of the lifting block; a connecting block is fixedly connected to one end of the electric push rod and slidably connected to the outer wall of the lifting block; a sliding block is slidably connected to the outer wall of the lifting block; a swing rod is slidably connected to the outer wall of the sliding block and fixedly connected to the rotation center of the operating shaft; and a telescopic rod is fixedly connected to the outer wall of the lifting block and fixedly connected to the bottom of the sliding block. To improve the switching effect between automatic and manual rotation of the operating shaft, when automatic rotation of the operating shaft is required, the electric push rod is opened. Through the connection of the limiting rod, the connecting block is driven to move up and down, causing the connecting block to squeeze the sliding block and causing the sliding block to slide synchronously along the inner wall of the slide groove and the limiting groove. This causes the swing rod to rotate, and the rotation of the swing rod drives the operating shaft to rotate automatically, improving the labor-saving operation of the press.
[0010] Preferably, the outer wall of the connecting block is fixedly connected to a limiting rod that is slidably connected to the outer wall of the lifting block.
[0011] Preferably, the sliding block is positioned on the motion trajectory of the connecting block.
[0012] Preferably, a sliding groove is provided at the connection between the outer wall of the lifting block and the sliding block, and a limit groove is provided at the connection between the outer wall of the swing rod and the sliding block.
[0013] Preferably, a rotating handle is fixedly connected to the outer wall of the operating shaft, and an operating handle is threadedly connected to the inner wall of the rotating handle.
[0014] Preferably, the outer wall of the operating handle is provided with an outer spiral, and the inner wall of the rotating handle is provided with an inner spiral that is threadedly connected to the outer wall of the outer spiral.
[0015] Preferably, an anti-slip ball is fixedly connected to the end of the operating handle.
[0016] Compared with the prior art, this utility model has at least the following beneficial effects:
[0017] In the above scheme, by setting a swing rod, when it is necessary to drive the operating shaft to rotate and lower the lifting block, in order to improve the switching effect of automatic and manual rotation of the operating shaft, when the operating shaft needs to be driven to rotate automatically, the electric push rod is opened, and through the connection of the limit rod, the connecting block is driven to move up and down, so that the connecting block squeezes the sliding block and drives the sliding block to slide synchronously along the inner wall of the slide groove and the limit groove, so that the swing rod rotates. The rotation of the swing rod drives the operating shaft to rotate automatically, improving the efficiency of the operator in operating the press. When the operating shaft needs to be operated manually, the electric push rod is closed, and the operator manually drives the operating handle, so that the operating handle drives the operating shaft to rotate.
[0018] In the above scheme, by setting external and internal helices, when the operating shaft needs to be manually driven, in order to improve the adjustment effect of the operating handle's length, the operating handle is rotated, and the length of the rotating handle and the operating handle changes due to the threaded connection of the external and internal helices.
