Description

Technical Field

[0001] The utility model belongs to the technical field of cold extrusion machines, in particular to an automatic loading and unloading device for cold extrusion machines. Background Art

[0002] Cold extrusion machine is a kind of equipment that uses cold extrusion technology to plastically deform metal materials. Its main working principle is to apply high pressure to metal materials at room temperature to make them plastically deform, so as to obtain products of desired shape and size.

[0003] For example, a cold extrusion device for extruding solid bars disclosed in a Chinese patent with publication number CN204523813U includes a hydraulic press of an upper oil cylinder, a hydraulic press of a lower oil cylinder, and a mold. The mold includes an upper mold fixing plate, an upper mold inner and outer core, a middle mold inner core, a lower mold inner core, and an ejector rod. The upper mold inner and outer cores are provided with a flange cap with a thread. The upper mold fixing plate is connected to the fixing groove of the upper machine table of the hydraulic press of the upper oil cylinder. The middle mold inner core is placed in the outer fixing sleeve through a conical sleeve and fits on the lower mold inner core. The lower mold inner core is fixed to the lower mold support plate of the lower machine table plate groove by a connecting flange and a screw. The middle mold inner core and the lower mold inner core are pressed tightly with a common conical sleeve by interference fit. The upper and lower contact mating surfaces are designed with absolute plane precision. The middle mold core and the lower mold core are supported by the two end surfaces of the lower mold pad to prevent the mold core from moving down and becoming loose. The connecting flange on the upper circular boss is fixed to the lower mold support plate by screws. A flat cavity is provided in the center of the lower mold core. The lower mold flat cavity and the mold core need to be inserted into the ejector rod of the lower mold; the ejector rod is aligned and fixedly connected with the center of the piston of the lower cylinder of the hydraulic press, and a threaded pull rod is provided on the fixed plate. The ejector rod passes through the lower mold fixed plate to align the center and fix the lower mold plate. The ejector rod moves freely up and down in the lower mold core, and the up and down stroke distance is determined to the precise position by the stroke switch positioning of the cylinder push rod.

[0004] The above-mentioned cold extrusion device is actually a cold extrusion press (also known as a hydraulic press). In the current cold extrusion process, the processing of the blank involves two key steps: first, the blank to be processed is accurately placed in the inner core of the middle mold for extrusion molding, and second, after the product is extruded, it needs to be efficiently removed from the mold. However, the currently commonly used solution is to rely on separate loading and unloading devices to perform these two steps respectively, that is, after the unloading device completes the unloading operation, the loading device starts a new round of loading. This mode not only significantly reduces the overall loading and unloading efficiency, but also leads to an increase in the equipment footprint, which is not conducive to the optimal use of production space. Utility Model Content

[0015] The automatic loading and unloading device equipped with the cold extrusion machine disclosed in the present application realizes the orderly arrangement and operation of the loading mechanism and the unloading mechanism through the precise lifting and sliding functions of the linear rail assembly on the machine base. The linear rail assembly first slides to the preset position to ensure that the unloading mechanism is accurately located above the formed blank, and the loading mechanism corresponds to the top of the blank to be processed.

[0023] Reference Figure 1This embodiment discloses an automatic loading and unloading device for a cold extrusion machine, which is equipped with a machine base 1 on which a slidable linear rail assembly 2 is installed. The lifting and lowering action of this assembly is realized by the linear rail motor driving the screw 6 to rotate, thereby driving the sliding of the linear rail assembly 2. On the linear rail assembly 2, a feeding mechanism 4 and a feeding mechanism 3 are arranged in order, and the two realize synchronous loading and unloading operations. Specifically, the feeding mechanism 4 is arranged at the end of the linear rail assembly 2, and the feeding mechanism 3 is located at the rear side thereof. A material rack 10 is connected to the machine base 1, and the material rack 10 is located between the feeding mechanism 3 and the feeding mechanism 4. The precise lifting and sliding of the linear rail assembly 2 on the machine base 1 ensures the orderly arrangement and efficient operation of the feeding mechanism 3 and the feeding mechanism 4.

[0024] Reference Figure 2 The unloading mechanism 4 includes a mounting plate 41 connected to the linear rail assembly 2 and a suction plate 42 mounted on the mounting plate 41. The mounting plate 41 is detachably connected to the linear rail assembly 2 by bolts. Two suction plates 42 are provided. A negative pressure pipe (not shown) is connected to the top of the suction plate 42. The loading mechanism 3 includes a driving member 31 provided on the linear rail assembly 2 and two clamping arms 32 slidably provided at the bottom of the driving member 31 and used for clamping materials. The driving member 31 is driven by a rodless cylinder, which can drive the two clamping arms 32 to move toward and away from each other to clamp and discharge materials.

[0025] Reference Figure 3 , the base 1 is provided with a lifting mechanism and a guide mechanism for driving the linear rail assembly 2 to rise and fall. The lifting mechanism includes an active motor (not shown) arranged at the lower end of the linear rail assembly 2, a driven motor 5 driven by a belt with the active motor, a screw rod 6 rotatably arranged at the bottom end of the driven motor 5, and a nut seat 7 arranged on the base 1, wherein the nut seat 7 is threadedly connected with the screw rod 6, and the guide mechanism includes a guide rail 8 arranged on the base 1, and a slider 9 arranged at the lower end of the linear rail assembly 2 and slidably engaged with the guide rail 8. The active motor drives the driven motor 5 to rotate through the belt, and the driven motor 5 drives the screw rod 6 to rotate. Since the screw rod 6 is threadedly connected with the nut seat 7 on the base 1, and under the cooperation of the guide rail 8 and the slider 9, the lifting and falling of the linear rail assembly 2 is realized. Two guide mechanisms are provided, which are located on both sides of the lifting mechanism to improve the stability of the linear rail assembly 2.

[0026] During operation, the linear rail assembly 2 first slides to a preset position to ensure that the unloading mechanism 4 is accurately aligned with the top of the formed blank, and the loading mechanism 3 corresponds to the top of the rack 10. Then, the linear rail assembly 2 is lowered to allow the loading assembly to accurately clamp the blank to be processed, while the unloading assembly simultaneously absorbs the completed blank.

[0027] After completing the above actions, the linear rail assembly 2 moves up and slides to the specified position, the unloading mechanism 4 moves to the unloading area to complete the unloading operation, and the loading mechanism 3 moves to the top of the mold to prepare for a new round of loading operations. The entire process realizes the synchronization of loading and unloading, greatly improving the overall loading and unloading efficiency, and effectively optimizing the spatial layout of the equipment and reducing the floor space.

[0028] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
