Abstract
Description
Technical Field
[0001] This utility model relates to the field of feeding equipment technology, and in particular to a workpiece driving mechanism. Background Technology
[0002] Electrical discharge wire cutting (EDM) utilizes the principle of "electrical discharge machining" to electro-erode conductive materials to achieve the machining purpose. The basic principle is that free positive ions and electrons accumulate in an electric field, quickly forming an ionized conductive channel. A current forms between the two plates, causing numerous collisions between particles, creating a plasma region that rapidly heats up to 8000 to 12000 degrees Celsius, instantly melting some material on the surfaces of the two conductors. For mold processing, EDM offers significant advantages over traditional cutting methods in cutting tapered and irregularly shaped surfaces, achieving precision down to 0.001 mm, with surface quality approaching grinding levels. It also significantly improves the accuracy of cross-sections and longitudinal sections.
[0003] When performing wire electrical discharge machining on cylindrical workpieces, workers need to move the cylindrical workpieces from a low position to the cutting station at equal intervals to perform the cutting operation. This process is not only labor-intensive, but also prone to changes in the feeding interval due to human error, which in turn affects the processing progress of the wire electrical discharge machining equipment. Utility Model Content
[0004] In view of this, the purpose of this utility model is to propose a workpiece driving mechanism to solve the problems mentioned above, which require workers to carry cylindrical workpieces from a low position to the cutting station at equal time intervals, resulting in high labor intensity and easy changes in the feeding interval that affect the processing progress of the wire EDM equipment.
[0005] To achieve the above objectives, this utility model provides a workpiece driving mechanism, including symmetrically arranged support frames, with a support platform located on one side of an electrical discharge wire cutting device fixed to one side of the two support frames that are close to each other, and further including: An intermittent lifting mechanism is provided on two support frames for intermittently conveying cylindrical workpieces to a support platform. The intermittent lifting mechanism includes two longitudinally distributed conveyor rollers, a conveyor belt located between the two support frames and connecting the two conveyor rollers, support units equally spaced on the conveyor belt for lifting the cylindrical workpieces, and a driver provided on one side of one of the support frames for driving the conveyor rollers to rotate intermittently.
[0006] Preferably, the support platform has a slot for the support unit to pass through, and the top of the support platform has an inclined surface.
[0007] Preferably, the support unit includes a fixed plate fixedly mounted on the conveyor belt, two adjustable support members mounted on the fixed plate for supporting cylindrical workpieces, and a locking member mounted on the fixed plate for fixing the position of the support plate.
[0008] Preferably, the support member includes a support plate that slides on one side of the fixed plate to support the cylindrical workpiece. A groove is provided on one side of the fixed plate. A slide block that slides inside the groove is fixedly connected to one end of the support plate. A stabilizing groove that communicates with the groove is provided at the top of the fixed plate. A positioning rod that slides inside the stabilizing groove is fixedly connected to the top of the slide block.
[0009] Preferably, the locking element includes a threaded groove formed on the positioning rod, and a locking block for abutting against the top surface of the fixing plate is threadedly connected to the positioning rod.
[0010] Preferably, the support plate is configured as an arc-shaped structure.
[0011] Preferably, the driver includes sprockets fixedly mounted on one end of two conveying rollers and longitudinally distributed, a chain connecting the two sprockets, a gear connected to one end of one of the conveying rollers, a motor mounted on one side of the support frame, and a half gear meshing with the gear on the motor output shaft.
[0012] The beneficial effects of this utility model are as follows: By setting up a support frame, support platform, conveyor rollers and conveyor belt, it is convenient for workers to place cylindrical workpieces on the support unit at a low position. The driver realizes the intermittent rotation of the conveyor rollers, which in turn drives the conveyor belt to realize the intermittent movement of the support unit. This facilitates the transport of cylindrical workpieces from a low position to a high position for loading into the wire EDM equipment, providing convenience for the operation of the wire EDM equipment. At the same time, the intermittent lifting of the support unit effectively provides time for workers to place cylindrical workpieces on the support unit. Attached Figure Description

[0018] This specification provides one or more embodiments of a workpiece driving mechanism, such as... Figure 1 , Figure 2 and Figure 3 As shown, the device includes symmetrically arranged support frames 1, with a support platform 2 located on one side of the wire EDM equipment fixed to one side of the two support frames 1 that are close to each other. It also includes: An intermittent lifting mechanism is provided on two support frames 1 for intermittently conveying cylindrical workpieces to a support platform 2. The intermittent lifting mechanism includes two longitudinally distributed conveyor rollers 3, a conveyor belt 4 located between the two support frames 1 and connecting the two conveyor rollers 3, support units equally spaced on the conveyor belt 4 for lifting the cylindrical workpieces, and a driver provided on one side of one of the support frames 1 for driving the conveyor rollers 3 to rotate intermittently.
[0019] In use, the operator can easily place the cylindrical workpiece on the support unit at a low position. Then, the driver realizes the intermittent rotation of the conveyor roller 3, which in turn causes the conveyor belt 4 to drive the support unit to move intermittently, so as to transport the cylindrical workpiece from a low position to a high position and transport it to the side of the wire EDM equipment, thus realizing the loading of the wire EDM equipment. At the same time, due to the intermittent lifting of the support unit, it effectively provides time for the operator to place the cylindrical workpiece on the support unit.
[0020] In embodiments of this utility model, such as Figure 1 , Figure 2 and Figure 3 As shown, the support platform 2 has a slot 10 for the support unit to pass through, and an inclined surface 9 is provided at the top of the support platform 2. This design, through the slot 10, facilitates the conveyor belt 4 to move the support unit downwards within the slot 10, allowing the cylindrical workpiece on the support unit to be supported on the support platform 2, effectively separating the cylindrical workpiece from the support unit and providing convenience for loading the cylindrical workpiece. The inclined surface 9 also allows for the movement of the cylindrical workpiece.
[0021] In embodiments of this utility model, such as Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the support unit includes a fixed plate 7 fixedly mounted on the conveyor belt 4, two adjustable support members mounted on the fixed plate 7 for supporting cylindrical workpieces, and a locking member mounted on the fixed plate 7 for fixing the position of the support plate 8. This design allows the support members to slide on the fixed plate 7 according to the length of the cylindrical workpiece, effectively adjusting the distance between the two support members and facilitating the conveying of workpieces of various sizes.
[0022] In embodiments of this utility model, such as Figure 1 , Figure 2 and Figure 3 As shown, the support member includes a support plate 8 that slides on one side of a fixed plate 7 to support a cylindrical workpiece. A groove 14 is provided on one side of the fixed plate 7. A slide block 15, which slides inside the groove 14, is fixedly connected to one end of the support plate 8. A stabilizing groove 16, which communicates with the groove 14, is provided at the top of the fixed plate 7. A positioning rod 17, which slides inside the stabilizing groove 16, is fixedly connected to the top of the slide block 15. This design allows the support plate 8 to move, causing the slide block 15 to slide inside the groove 14. The slide block 15 then drives the positioning rod 17 to slide on the stabilizing groove 16. This effectively improves the stability of the movement of the support plate 8 driven by the slide block 15, facilitating the support of both ends of the cylindrical workpiece by the two support plates 8, and providing convenience for loading the cylindrical workpiece.
[0023] In embodiments of this utility model, such as Figure 5As shown, the locking element includes a threaded groove on the positioning rod 17, and a locking block 18 for abutting against the top surface of the fixing plate 7 is threaded onto the positioning rod 17. This design, by threading the locking block 18 onto the positioning rod 17, fixes the position of the positioning rod 17, thereby fixing the position of the support plate 8 and effectively improving the support stability of the support plate 8 for the cylindrical workpiece.
[0024] In embodiments of this utility model, such as Figure 1 , Figure 3 and Figure 4 As shown, the support plate 8 is configured with an arc-shaped structure. This design, through the arc-shaped support plate 8, facilitates stable support for the cylindrical workpiece, preventing the cylindrical workpiece from rolling and falling during the lifting process.
[0025] In embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the driver includes sprockets 5 fixedly mounted on one end of two conveying rollers 3 and longitudinally distributed, a chain 6 connecting the two sprockets 5, a gear 13 connected to one end of one of the conveying rollers 3, a motor 11 mounted on one side of the support frame 1, and a half gear 12 that meshes with the gear 13 fixedly sleeved on the output shaft of the motor 11. This design involves starting motor 11, which drives half gear 12 to rotate. Through the meshing connection between half gear 12 and gear 13, gear 13 drives one of the conveyor rollers 3 to rotate. In turn, conveyor roller 3 drives one of the sprockets 5 to rotate. Through the action of chain 6, the other sprocket 5 drives the other conveyor roller 3 to rotate, facilitating the intermittent rotation of the two conveyor rollers 3. The two conveyor rollers 3 cause the conveyor belt 4 to move intermittently, which facilitates the intermittent lifting of the cylindrical workpiece by the support plate 8 driven by the conveyor belt 4. During the stop movement, time is provided for the operator to place the cylindrical workpiece on the lower support plate 8. At the same time, the cylindrical workpiece is intermittently fed onto the support platform 2, realizing the orderly feeding of cylindrical workpieces from the lower position. This avoids the operator having to carry the workpiece to a higher position for feeding, reducing labor intensity. At the same time, this design can also keep the feeding interval constant, effectively realizing the stable processing of the EDM wire cutting equipment.
