Description
Technical Field
The utility model relates to a press machine, in particular to an electric press machine.
Background
A press is a machine that uses pressure to process products such as metal, plastic, rubber, wood, powder, etc. It is commonly used in press processes and press forming processes, such as: forging, stamping, cold extrusion, straightening, bending, flanging, sheet drawing, powder metallurgy, press fitting, and the like.
The common press is a hydraulic press, the pressure of the hydraulic press is derived from hydraulic oil, and the pressure of the press is difficult to accurately and rapidly control. There are also electric presses on the market, which can rapidly and accurately regulate the pressure of the press, but as a load cell for detecting the pressure on the press, a certain pretightening force exists when the load is removed, and after the load is removed, the pretightening force also causes the load cell to be pressed, and the existence of the pressed load cell can not accurately reflect the pressure of the press, so that improvement is necessary.
Disclosure of Invention
Aiming at the defects of the prior art, the utility model provides an electric press machine, and after the load is removed, the load cell can accurately reflect the pressure of the press machine.
The technical scheme adopted for solving the technical problems is as follows: the utility model provides an electric press, includes the base, be fixed with the one end of many guide bars on the base, the other end of guide bar is fixed on last plummer, go up the plummer on be provided with motor assembly, motor assembly drive movable block motion, the movable block cover is in on the guide bar, be provided with the fixed block on the base, the top of movable block has the load cell subassembly, motor assembly includes motor, screw rod group, bearing frame group and linking seat, the one end top of the screw rod of screw rod group is in on the movable block, the other end of the screw rod of screw rod group is connected the bearing frame group, the bearing frame group set up in go up the plummer and via linking seat connects the motor, the screw rod top of screw rod group and load cell subassembly contact each other, load cell subassembly includes fixed block and load cell, the bolt passes behind the fixed block with the load cell links to each other, the cover is equipped with the gasket on the bolt, the gasket with have the clearance between the bolt.
In the above technical scheme, preferably, a through hole is formed in the middle of the load cell, a protrusion is arranged at the bottom of the bolt fixing block, and the protrusion is matched with the through hole to realize connection of the load cell and the bolt fixing block.
In the above technical scheme, preferably, the top of the fixed block is provided with a sinking table, and the screw rod is connected in the sinking table.
In the above technical solution, preferably, the gap is 0.1mm.
The beneficial effects of the utility model are as follows: the gap is formed between the gasket and the bolt, and the pre-tightening force is not used between the load element and the fixed block after the load is removed by the press due to the gap, so that the load on the load element can be reflected more truly.
Drawings
Figure 1 is a cross-sectional view of the present utility model.
Fig. 2 is a schematic diagram of a pair of load cell components.
Detailed Description
The utility model is described in further detail below with reference to the attached drawings and detailed description:
referring to fig. 1 to 2, an electric press comprises a base 1, one end of a plurality of guide rods 2 is fixed on the base 1, the other end of each guide rod 2 is fixed on an upper bearing table 3, a motor assembly 4 is arranged on the upper bearing table 3, the motor assembly 4 drives a moving block 5 to move, the moving block 5 is sleeved on each guide rod 2, a fixed block 11 is arranged on the base 1, and a load cell assembly 6 is arranged at the top of the moving block 5.
The motor assembly 4 includes a motor 41, a screw rod assembly 42, a bearing seat assembly 43 and a connecting seat 44, wherein one end of a screw rod 421 of the screw rod assembly 42 is propped against the moving block 5. The other end of the screw 421 of the screw group 42 is connected to the bearing block group 43, and the bearing block group 43 is provided on the upper table 3 and is connected to the motor 41 via the connection base 44.
The top of the screw 421 of the screw group 42 is connected with the load cell assembly 6, the load cell assembly 6 comprises a fixed block 61 and a load cell 62, a bolt 63 penetrates through the fixed block 61 and then is connected with the load cell 62, a gasket 631 is sleeved on the bolt 63, and a gap is formed between the gasket 631 and the bolt 62, and the gap is 0.1mm. Because of the gap, the load on the load element can be reflected more truly because the pre-tightening force is not used between the load element and the fixed block after the load is removed by the press machine.
For positioning and fixing the load cell 62 and the fixing block 61, a through hole 621 is arranged in the middle of the load cell 62, a protrusion 611 is arranged at the bottom of the fixing block 61, and the protrusion 611 and the through hole 621 are matched to realize connection of the load cell and the fixing block.
The top of the fixed block 61 is provided with a sinking table 612, and the screw 421 is propped in the sinking table 612.
