Description

Technical Field

[0001] This utility model relates to the field of press technology, and in particular to the guiding mechanism of the rolling linear guide pair of the press. Background Technology

[0002] A press is a forging machine that applies pressure to metal or other materials, causing plastic deformation or separation to obtain workpieces of desired shapes and sizes. It is used in the automotive, aerospace, machining, and home appliance manufacturing industries. Structurally and in terms of working principle, a press consists of a frame, working mechanism, transmission system, operating system, and auxiliary system. Its core working mechanism utilizes an electric motor to drive the transmission system, converting rotary motion into the reciprocating linear motion of a slide block. When the slide block drives the upper die downwards, it cooperates with the lower die fixed on the worktable, applying pressure to the blank placed between the dies to complete the stamping, forging, bending, and shearing processes. Based on the driving method, presses can be classified into... There are mechanical presses and hydraulic presses. Mechanical presses transmit power through cranks and connecting rods, and are characterized by high working speed and high production efficiency, making them suitable for mass production. Hydraulic presses use hydraulic oil as the working medium and utilize the pressure generated by a hydraulic pump to drive the movement of a slide. They offer flexible adjustment of pressure and stroke, can withstand large impact loads, and are suitable for processing complex-shaped workpieces. In addition, presses can be classified by tonnage into small, medium, and large presses, and by structure into open and closed presses. Different types of presses can meet diverse processing needs. As an important forging and pressing machine, the performance of the guiding mechanism of the press is crucial to processing accuracy and production efficiency.

[0003] With the increasing demands for high precision, high speed, and high efficiency in modern manufacturing, rolling linear guide pairs are gradually replacing traditional sliding guides. A rolling linear guide pair consists of a guide rail, slider, rolling elements, reverser, and cage. It boasts advantages such as low friction coefficient, high guiding accuracy, high rigidity, high repeatability, and long service life, better meeting the high-speed, precision motion requirements of presses. However, in practical applications, the complex structure of rolling linear guide pairs often necessitates significant time-consuming disassembly for lubrication, severely impacting equipment efficiency. Installing an automatic lubrication device on the slider, which indirectly controls the valve's opening and closing by controlling the motor, allows for timely and automatic lubrication addition. This not only saves time spent disassembling the device, improving operational efficiency, but also avoids wear on components during disassembly. Furthermore, the rolling linear guide pair's material is sensitive to temperature changes. High temperatures cause thermal expansion and contraction, altering the fit clearance and affecting motion accuracy, while low temperatures degrade lubricant performance, exacerbating friction and wear. Therefore, proper temperature control is essential. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a rolling linear guide pair guiding mechanism for a press, aiming to improve the problem that in the prior art, the rolling linear guide pair often has a complex structure, requiring a lot of time to disassemble when adding lubricant, which seriously affects the working efficiency of the equipment.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a rolling linear guide pair guiding mechanism for a press, including a slide rail, a slider slidably connected to the outer wall of the slide rail, a branch pipe connected to the top of the slider, a valve chamber connected to the top of the branch pipe, a main pipe connected to the top of the valve chamber, a hollow ball rotatably connected to the inner wall of the valve chamber, a switch motor arranged on the left side of the valve chamber, a rotating block fixedly connected to the output end of the switch motor, a side cover slidably connected to the outer wall of the slider, threaded columns fixedly connected to the front and rear ends of the left and right sides of the slider, nuts threadedly connected to the outer wall of the threaded columns, and a temperature-regulating mechanism arranged on the rear side of the slide rail. The function of the temperature-regulating mechanism is to ensure that the temperature of the slide rail and the slider is always at a suitable working temperature.

[0006] As a further description of the above technical solution:

[0007] The constant temperature mechanism includes a heating wire, the outer wall of which is fixedly connected to the bottom of the inner wall of the slider. A cooling pipe is fixedly connected to the inner wall of the slide rail. The left end of the cooling pipe is connected to a return pipe, the right end of which is connected to a storage tank. The right side of the storage tank is connected to a connecting pipe. A water pump is installed in the middle of the connecting pipe. A cooling motor is installed at the bottom of the return pipe. A rotating column is fixedly connected to the output end of the cooling motor, and a fan blade is fixedly connected to the top of the rotating column.

[0008] As a further description of the above technical solution:

[0009] Both ends of the slide rail are fixedly connected to baffles, and anti-collision pads are fixedly connected to adjacent sides of the two baffles.

[0010] As a further description of the above technical solution:

[0011] A solid ball is slidably connected to the inner wall of the slider, and shock-absorbing chambers are fixedly connected to both the left and right sides of the side cover.

[0012] As a further description of the above technical solution:

[0013] The inner walls of the shock-absorbing chambers are slidably connected with pistons, and springs are provided on adjacent sides of the two pistons.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, by removing the nut and moving the side cover away from the slider, the solid ball can be taken out from the inside of the slider. When the slider hits the baffle, the baffle pushes the piston into the shock absorption chamber through the connecting column, causing the piston to squeeze the spring. The spring absorbs the force generated by the impact. When the lubrication between the slider and the slide rail fails, the switch motor drives the hollow ball to rotate through the rotating block. The lubricating oil flows into the solid ball inside the slider through the main pipe and branch pipes. The solid ball applies the lubricating oil to the surface of the contact between the slide rail and the slider.

[0022] 2. In this utility model, when the temperature is too high, the water pump draws the coolant into the connecting pipe, allowing the coolant to flow into the cooling pipe through the connecting pipe. The coolant continuously absorbs heat, and after absorbing heat, the coolant flows from the cooling pipe into the return pipe. While the coolant is passing through the return pipe, the cooling motor is started. The cooling motor drives the fan blades to rotate through the rotating column, and the fan blades help dissipate the heat absorbed by the coolant. When the temperature is too low, the heating wire continuously heats the slider and the area around the slider. Attached Figure Description

[0039] Working principle: Driven by a driving device, slider 7 slides continuously along the surface of slide rail 1, causing solid ball 22 to move. Since solid ball 22 is in contact with slide rail 1, it rolls continuously inside slider 7. When solid ball 22 needs to be replaced, turn nut 9 to remove it from threaded post 8, and move side cover 5 away from slider 7. This allows solid ball 22 to be removed from inside slider 7. If slider 7 moves too fast, it will collide with baffle 16, which pushes connecting post 24 into the shock-absorbing chamber 19. The piston 23 is pushed into the damping chamber 19, causing the piston 23 to continuously compress the spring 21. The spring 21 absorbs the force generated by the impact. When the lubrication between the slider 7 and the slide rail 1 fails, the main pipe 4 is connected to the pipeline that delivers lubricating oil, and the switch motor 3 is started. The switch motor 3 drives the rotating block 10 to rotate, and the rotating block 10 drives the hollow ball 12 to rotate until the valve chamber 11 is connected. The lubricating oil flows into the solid ball 22 inside the slider 7 through the main pipe 4 and the branch pipe 6. The rolling of the solid ball 22 drives the lubricating oil to move, so that the lubricating oil is coated on the contact surface of the slide rail 1 and the slider 7.

[0040] When the temperature is too high, the water pump 206 is started, and the water pump 206 draws the coolant stored in the storage tank 204 into the connecting pipe 205, so that the coolant flows into the cooling pipe 202 through the connecting pipe 205. When the coolant flows through the cooling pipe 202, it continuously absorbs the heat of the slide rail 1 and the area around the slide rail 1. After absorbing the heat, the coolant flows from the cooling pipe 202 into the return pipe 203. At the same time as the coolant passes through the return pipe 203, the cooling motor 207 is started, and the cooling motor 207 drives the rotating column 208 to rotate. The rotating column 208 drives the fan blade 209 to rotate, and the fan blade 209 accelerates the airflow speed near the return pipe 203, thereby helping to dissipate the heat absorbed by the coolant. After dissipating the heat, the coolant finally flows back to the storage tank 204 from the return pipe 203. When the temperature is too low, the heating wire 201 is connected to the power supply, so that the heating wire 201 continuously heats the slider 7 and the area around the slider 7.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
