Technical Field

[0001] This application relates to the field of metal extrusion presses, and in particular, to a silicon-aluminum alloy extrusion press. Background Art

[0002] A metal extrusion press is a device for realizing metal extrusion processing. Metal extrusion is processed by using metal plastic pressure forming, and can process metal ingots into profiles such as tubes and rods.

[0003] The related metal extrusion press includes a workbench and a hydraulic cylinder. The cylinder body of the hydraulic cylinder is fixed on one side of the workbench. The piston rod of the hydraulic cylinder can slide in the cylinder body. The user places the workpiece on the workbench, so that the piston rod can slide and abut against the workpiece, and then the workbench and the piston rod jointly extrude the workpiece to complete the processing.

[0004] The above-mentioned related technical solutions have the following defects: during the telescopic process of the hydraulic cylinder, the user needs to manually control the feed amount of the hydraulic cylinder, and it is difficult to accurately control the displacement of the hydraulic cylinder during the processing, resulting in difficult control of the quality of the workpiece after extrusion processing. Utility Model Content

[0005] In order to facilitate the user to accurately control the telescopic amplitude of the hydraulic cylinder, this application provides a silicon-aluminum alloy extrusion press.

[0006] A silicon-aluminum alloy extrusion press provided by this application adopts the following technical solutions:

[0007] A silicon-aluminum alloy extrusion press includes a workbench, a hydraulic cylinder, a travel frame, a fixed frame, and a plurality of travel switches. The hydraulic cylinder includes a cylinder body and a piston rod. The cylinder body is installed above the workbench. A fixed plate is installed on the workbench. The piston rod is slidably connected to the cylinder body. The piston rod is perpendicular to the fixed plate. The travel frame is fixed on the piston rod. One end of the fixed frame is fixed on the workbench. The length direction of the fixed frame is parallel to the length direction of the hydraulic cylinder. The travel switches are fixed on the fixed frame. The plurality of travel switches are arranged at intervals along the length direction of the fixed frame. When the travel frame moves with the piston rod, it triggers the travel switch.

[0008] By adopting the above technical solutions, by setting a hydraulic cylinder on the workbench, the user can place the workpiece on the fixed plate, so that the piston rod of the hydraulic cylinder abuts against the workpiece to achieve the effect of extruding the workpiece. By setting a fixed frame on the workbench and a plurality of travel switches on the fixed frame, when the hydraulic cylinder expands and contracts, the travel frame can move and trigger the travel switch. After the travel switch is triggered, it can transmit an electrical signal. After the controller receives the electrical signal, it controls the hydraulic cylinder to stop moving, thereby improving the accuracy when the hydraulic cylinder expands and contracts, and improving the processing quality of the workpiece extrusion.

[0009] Optionally, a scale is provided on the fixed frame, and the length direction of the scale is parallel to the length direction of the fixed frame.

[0010] By adopting the above technical solution, a scale is set on the fixed frame, and multiple travel switches are set on one side of the scale. The user can check the spacing between the travel switches through the scale, which makes it convenient for the user to select a suitable travel switch to limit the movement of the hydraulic cylinder according to the range of extension and retraction of the hydraulic cylinder.

[0011] Optionally, the zero scale line of the scale coincides with the plane where the fixed plate is located.

[0012] By adopting the above technical solution, the user can further determine the distance between the piston rod and the fixed plate when the hydraulic cylinder moves according to the indication of the scale, thereby facilitating the user to control the feed amount of the hydraulic cylinder according to the process requirements.

[0013] Optionally, the travel switch includes a body, a rocker and an abutment wheel. The body is mounted on a fixed frame, one end of the rocker is rotatably connected to the body, and the other end is rotatably connected to the abutment wheel. The travel frame toggles the rocker through the abutment wheel, and a torsion spring is provided at the rotation connection between the rocker and the body. The torsion spring is used to automatically reset the rocker and make it stationary on the moving path of the travel frame.

[0014] By adopting the above technical solution, a rocker is arranged on the machine body, so that when the piston rod drives the travel frame to move, the lever can move the rocker, and the travel switch is triggered when the rocker rotates relative to the machine body. When the piston rod drives the travel frame to continue to move, the lever is disconnected from the rocker, and the rocker is reset under the drive of the torsion spring. By arranging multiple travel switches on the fixed frame, the user can select a travel switch with a suitable position according to the length that the hydraulic cylinder needs to be extended and receive the electrical signal of the travel switch. When the travel frame passes through other travel switches during the extension and retraction of the hydraulic cylinder, the other travel switches will not block the moving path of the travel frame.

[0015] Optionally, a slide groove is provided on the fixing frame, and the machine body is slidably connected in the slide groove. A fixing bolt is provided on the machine body, and the fixing bolt passes through the machine body and is threadedly connected to the machine body, and the end of the fixing bolt abuts against the fixing frame.

[0016] By adopting the above technical solution, a slide groove is provided on the fixed frame so that the machine body can slide in the slide groove, thereby facilitating the user to adjust the position of the travel switch on the fixed frame according to the scale. After the user slides the travel switch to a predetermined position, the user can screw the fixing bolt so that the fixing bolt abuts against the fixed frame, thereby enabling the fixed travel switch to be fixed at different positions on the fixed frame.

[0017] Optionally, the travel frame is made of rubber material, the travel frame is sleeved on the piston rod, a through hole is provided on the travel frame, the piston rod is inserted into the through hole and has an interference fit with the through hole.

[0018] By adopting the above technical solution, by using a rubber material to make the travel rack, the travel rack can elastically deform and be sleeved on the piston rod, which facilitates the user to install the travel rack on the piston rod.

[0019] Optionally, the travel rack is made of a hard material. A through hole is provided on the travel rack, and the piston rod is inserted into the through hole. A plurality of bolts are provided on the travel rack. The bolts penetrate through the travel rack and are threadedly connected to the travel rack. The end of the bolt abuts against the piston rod.

[0020] By adopting the above technical solution, by using a hard material to make the travel rack, the travel rack has better structural strength. When the travel rack is installed on the piston rod, the travel rack is kept in a straight state, reducing the probability of deformation of the travel rack, thereby improving the accuracy of the travel switch controlling the movement of the hydraulic cylinder. When the travel rack toggles the travel switch, the probability of deformation of the travel rack can be reduced, and the accuracy of the travel switch controlling the movement of the hydraulic cylinder can be improved.

[0021] Optionally, the hydraulic cylinder is vertically arranged, and the fixing plate is horizontally arranged.

[0022] By adopting the above technical solution, by vertically arranging the hydraulic cylinder and horizontally arranging the fixing plate below the hydraulic cylinder, the user can place the workpiece on the horizontal fixing plate, so that the piston rod of the hydraulic cylinder vertically drops and presses the workpiece, improving the processing efficiency.

[0023] In summary, the beneficial technical effects of this application are as follows:

[0024] 1. By arranging a hydraulic cylinder on the workbench, the user can place the workpiece on the fixing plate, and make the piston rod of the hydraulic cylinder abut against the workpiece to achieve the effect of pressing the workpiece. By arranging a fixing frame on the workbench and arranging a plurality of travel switches on the fixing frame, when the hydraulic cylinder expands and contracts, the travel rack can move and trigger the travel switch. After the travel switch is triggered, it can transmit an electrical signal. After the controller receives the electrical signal, it controls the hydraulic cylinder to stop operating, thereby improving the accuracy when the hydraulic cylinder expands and contracts and improving the processing quality of pressing the workpiece;

[0025] 2. By arranging a scale on the fixing frame and arranging a plurality of travel switches on one side of the scale, the user can view the distance between the travel switches through the scale, thereby facilitating the user to select a suitable travel switch according to the range of expansion and contraction required by the hydraulic cylinder to limit the operation of the hydraulic cylinder;

[0026] 3. By setting a rocker on the machine body, when the piston rod drives the stroke frame to move, the lever can push the rocker. When the rocker rotates relative to the machine body, the travel switch is triggered. After the piston rod drives the stroke frame to continue moving, the lever is disengaged from the rocker. At this time, the rocker is reset under the drive of the torsion spring. By setting multiple travel switches on the fixed frame, the user can select a travel switch with a suitable position according to the required elongation length of the hydraulic cylinder and receive the electrical signal of this travel switch. When the stroke frame passes by other travel switches during the telescopic process of the hydraulic cylinder, the other travel switches will not block the movement path of the stroke frame.

Detailed Description of the Embodiment

[0032] The following further describes the present application in detail with reference to the drawings.

[0033] The embodiment of the present application discloses a silicon-aluminum alloy extruder. Refer to Figure 1, including a workbench 1, a hydraulic cylinder 2, a travel frame 3, a fixed frame 4 and multiple travel switches 5. The workbench 1 is fixedly arranged, and a fixed plate 11 is arranged on the workbench 1. The fixed plate 11 is horizontally arranged. The hydraulic cylinder 2 is vertically arranged above the workbench 1. The hydraulic cylinder 2 includes a cylinder block 21 and a piston rod 22. The cylinder block 21 is fixed above the workbench 1, and the piston rod 22 is used to reciprocate vertically relative to the cylinder block 21. An operator can place the silicon aluminum alloy on the fixed plate 11, and the piston rod 22 can drop and squeeze the silicon aluminum alloy on the fixed plate 11. The travel frame 3 is fixed on the piston rod 22. When the piston rod 22 moves vertically, the travel frame 3 reciprocates vertically with the piston rod 22. The fixed frame 4 is vertically arranged, and the lower end of the fixed frame 4 is fixed on the workbench 1. The length direction of the fixed frame 4 is parallel to the length direction of the hydraulic cylinder 2. Multiple travel switches 5 are installed on the fixed frame 4, and the travel switches 5 are arranged at intervals along the length direction of the fixed frame 4. When the hydraulic cylinder 2 acts, the travel frame 3 can move with the piston rod 22 and trigger the travel switches 5 in sequence. When the travel switch 5 is connected to the power supply circuit where the hydraulic cylinder 2 is located, the travel frame 3 triggering the travel switch 5 can make the hydraulic cylinder 2 stop acting, so that the end of the piston rod 22 can reciprocate within the control range of the travel switch 5, which can improve the extrusion effect on the silicon aluminum alloy and improve the movement accuracy of the hydraulic cylinder 2.

[0034] In other embodiments, the hydraulic cylinder 2 is horizontally arranged. The fixed plate 11 is vertically fixed on the workbench 1. When an operator abuts the silicon aluminum alloy against one side of the fixed plate 11, the hydraulic cylinder 2 can extend and squeeze the silicon aluminum alloy.

[0035] Refer to Figure 1 and Figure 2 , a scale 41 is arranged on the fixed frame 4. The length direction of the scale 41 is parallel to the length direction of the fixed frame 4, and the zero scale line of the scale 41 coincides with the plane where the fixed plate 11 is located. When the travel switch 5 is arranged on the fixed frame 4, an operator can select the travel switch 5 connected to the power supply circuit of the hydraulic cylinder 2 according to the scale 41, so that the hydraulic cylinder 2 can expand and contract within a specific length range, which further facilitates the operator to extrude and process the silicon aluminum alloy according to the process requirements.

[0036] Refer to Figure 2, a lever 31 is provided on the travel frame 3, and the lever 31 is used to abut against the travel switch 5 and trigger the travel switch 5. The travel switch 5 includes a body 51, a rocker 52 and an abutment wheel 53. The body 51 is installed on the fixed frame 4, one end of the rocker 52 is rotatably connected to the body 51, and the other end is rotatably connected to the abutment wheel 53. A torsion spring is provided at the rotation connection between the rocker 52 and the body 51. When the body 51 is fixed on the fixed frame 4, the rocker 52 maintains a vertical state relative to the fixed frame 4 in a natural state. When the travel frame 3 moves with the piston rod 22, the lever 31 can abut against the abutment wheel 53 when it moves vertically. At this time, the rocker 52 rotates relative to the body 51, and the travel switch 5 is triggered.

[0037] Reference Figure 2 , a plurality of travel switches 5 are arranged on the fixed frame 4, and the travel switches 5 include a starting switch and a plurality of end switches. The starting switch is installed on the upper side of the fixed frame 4, and the plurality of end switches are arranged at different positions on the lower side of the fixed frame 4. When the piston rod 22 moves upward, the piston rod 22 drives the travel frame 3 to move upward and contact the starting switch, at which time the hydraulic cylinder 2 stops contracting and starts to extend. When the hydraulic cylinder 2 needs to extend to a large extent, during the extension process of the hydraulic cylinder 2, the travel frame 3 first contacts a plurality of end switches, at which time the lever 31 can toggle the rocker 52 of the travel switch 5 and continue to move. The travel switch 5 toggled by the lever 31 is not connected to the power circuit or has been marked by the controller, and the travel switch 5 cannot control the hydraulic cylinder 2 to stop moving, and the piston rod 22 can continue to slide. By rotating and connecting the rocker 52 to the body 51, the probability of the travel switch 5 blocking the extension path of the hydraulic cylinder 2 can be reduced, so that the travel frame 3 on the hydraulic cylinder 2 can sequentially trigger a plurality of travel switches 5 until the energized travel switch 5 controls the hydraulic cylinder 2 to stop moving.

[0038] Reference Figure 2 , a slide groove 42 is provided on the fixing frame 4, and the length direction of the slide groove 42 is parallel to the length direction of the fixing frame 4. The body 51 is embedded and slidably connected in the slide groove 42, and the travel switch 5 can slide on the fixing frame 4 along the length direction of the fixing frame 4. A fixing bolt 511 is installed on the body 51, and the fixing bolt 511 passes through the body 51 and abuts on the surface of the fixing frame 4, so that the travel switch 5 can be fixed at different positions on the fixing frame 4. The user can adjust the position of the travel switch 5 according to the scale 41, so that the user can control the telescopic range of the hydraulic cylinder 2 conveniently, so that the hydraulic cylinder 2 can extrude the silicon aluminum alloy to a suitable thickness.

[0039] Reference Figure 3 In other embodiments, the travel frame 3 is made of rubber material, a through hole is provided in the middle of the travel frame 3, and the piston rod 22 can be inserted into the through hole and has an interference fit with the through hole. The travel frame 3 can be easily and quickly installed on the hydraulic cylinder 2.

[0040] Reference Figure 4, to improve the stiffness of the stroke frame 3, the stroke frame 3 can be made of metal materials. Through holes are provided on the stroke frame 3, and the piston rod 22 is inserted into the through holes. A plurality of bolts are provided on the stroke frame 3. The bolts penetrate through the stroke frame 3 and are threadedly connected to the stroke frame 3. The ends of the bolts can abut against the side wall of the piston rod 22, so that the stroke frame 3 can be installed on different hydraulic cylinders 2.

[0041] The implementation principle of the embodiment of the present application is as follows: By arranging the hydraulic cylinder 2 on the workbench 1, the piston rod 22 can move in the direction close to the fixing plate 11, thereby squeezing the silicon aluminum alloy placed on the fixing plate 11. By arranging the fixing frame 4 on the workbench 1 and arranging the scale 41 on the fixing frame 4, the user can determine the position of the travel switch 5 according to the scale 41, and then can determine the degree of squeezing of the silicon aluminum alloy by the piston rod 22, which is convenient for the user to adjust the moving range of the hydraulic cylinder 2 according to the process requirements.

[0042] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
