Description

Technical Field

[0001] The utility model relates to the field of casting shaping, in particular to a single-side driven shaping machine for castings. Background Art

[0002] Castings are widely used in various industrial fields, especially cylindrical castings. In the processing of cylindrical castings, shaping is one of the essential processing steps.

[0003] Most existing shaping machines use a cylinder to perform a single-sided shaping. If a secondary shaping is performed on the relative casting, secondary loading and shaping is required. One-time two-way shaping usually requires two driving devices in opposite directions, which is expensive to manufacture. In addition, most shaping machines use manual loading. Workers put the casting to be shaped into the shaping mold and then drive the shaping mechanism to perform shaping. Therefore, two-way shaping is time-consuming and labor-intensive, which is not conducive to improving productivity. For example, the shaping mechanism provided by a rounding shaping sleeve integrated molding device provided by Patent No. CN219597844U requires manual placement of the workpiece to be shaped into the shaping through hole and then drives the shaping mechanism to perform a single-sided shaping on the workpiece. Summary of the invention

[0004] In view of this, the utility model provides a single-side driven shaping machine for castings which can solve the above-mentioned problems.

[0005] A single-side driven shaping machine for castings comprises a workbench, a bracket arranged on the workbench, a transmission mechanism arranged on the workbench, a shaping mechanism arranged on the bracket, and a pickup unit arranged at one end of the transmission mechanism. The shaping mechanism comprises a mold unit arranged on the bracket, a core rod shaping unit arranged on the bracket and corresponding to the mold unit, a shaping drive mechanism arranged at one end of the core rod shaping unit, and a shaping unit connecting assembly arranged on the bracket and used to connect the mold unit, the core rod shaping unit, and the shaping drive mechanism.

[0006] Furthermore, the mold unit includes a support plate fixedly arranged on the workbench, an external shaping mold arranged on the support plate, and an external shaping mold limiting unit sleeved on the outside of the external shaping mold.

[0007] Furthermore, the external shaping mold includes a mold mounting seat, a material stripping drive shaft inserted in the mold mounting seat, and a mold body arranged between the material stripping drive shaft and the mold mounting seat.

[0008] Furthermore, one end of the material-removing driving shaft is inserted into the mold mounting seat and inserted into the mold body, and one end of the material-removing driving shaft facing away from the mold mounting seat is interconnected with the shaping unit connecting assembly.

[0009] Furthermore, the outer shaping mold limiting unit includes a limiting body and a limiting ring sleeve fixedly arranged at one end of the limiting body.

[0010] Furthermore, the mandrel shaping unit includes a shaping mandrel fixedly connected to the shaping drive mechanism, and a mandrel stabilizing assembly sleeved on the shaping mandrel, and the diameter of the free end of the shaping mandrel matches the diameter of the piece to be shaped.

[0011] Furthermore, the shaping drive mechanism includes a preparatory drive cylinder disposed on the bracket, and a shaping drive cylinder fixedly disposed at one end of the preparatory drive cylinder.

[0012] Furthermore, the shaping unit connecting assembly includes a movable plate slidably connected to the bracket, a guide rod arranged around the shaping drive cylinder, and an external shaping unit connecting member fixedly connected to the movable plate and arranged on the side of the movable plate facing away from the shaping drive mechanism.

[0013] Compared with the prior art, the utility model provides a single-side driven shaping machine for castings, which includes a transmission mechanism, a shaping mechanism, and a pickup unit. The shaping mechanism includes a mold unit arranged on the bracket, a mandrel shaping unit arranged on the bracket and corresponding to the mold unit, a shaping drive mechanism arranged at one end of the mandrel shaping unit, and a shaping unit connecting assembly arranged on the bracket and used to connect the mold unit, the mandrel shaping unit, and the shaping drive mechanism.

[0017] The following is a further detailed description of the specific embodiments of the present invention. It should be understood that the description of the present invention herein is not intended to limit the protection scope of the present invention.

[0018] like Figures 1 to 3 As shown, it is a structural schematic diagram of a single-side driven shaping machine for castings provided by the utility model. The single-side driven shaping machine for castings includes a workbench 1, a bracket 2 arranged on the workbench 1, a transmission mechanism 10 arranged on the workbench 1, a shaping mechanism 20 arranged on the bracket, and a pickup unit 30 arranged at one end of the transmission mechanism 10. It is conceivable that the single-side driven shaping machine for castings should also include some other functional components, such as assembly components, electrical connection components, control devices, sensor devices, etc., which are technologies well known to those skilled in the art and will not be described one by one here.

[0019] The workbench 1 and the bracket 2 are used to support the various mechanisms of the shaping machine so as to combine the various mechanisms into a coordinated whole. They are conventional arrangements in the art and are all prior art, and will not be described in detail here.

[0020] The transmission mechanism 10 includes a transmission unit 11 and a driving motor 12 arranged on one side of the transmission unit 11. The transmission unit 11 includes a mounting frame 111 arranged on the workbench 1, a transmission belt 112 arranged on the mounting frame 111, and a limiting groove 113 arranged at one end of the transmission belt 112. The driving motor 112 is fixedly arranged on one side of the mounting frame 111 to drive the transmission belt 112 to move. The limiting groove 113 is arranged at one end of the transmission belt 112 to prevent the casting from falling due to inertia after the transmission is completed. The mounting frame 111, the transmission belt 112, and the limiting groove 113 are all existing technologies and will not be described in detail here.

[0021] The shaping mechanism 20 includes a mold unit 21 arranged on the bracket 2, a core rod shaping unit 22 arranged on the bracket 2 and corresponding to the mold unit 21, a shaping drive mechanism 23 arranged at one end of the core rod shaping unit 22, and a shaping unit connecting assembly 24 arranged on the bracket 2 and used to connect the mold unit 21, the core rod shaping unit 22, and the shaping drive mechanism 23.

[0022] The mold unit 21 includes a support plate 211 fixedly disposed on the workbench 1 , an external shaping mold 212 disposed on the support plate 211 , and an external shaping mold limiting unit 213 sleeved on the outside of the external shaping mold 212 .

[0023] The support plate 211 is used to place and support the external shaping mold 212 and the external shaping mold limiting unit 213, and a plurality of mounting holes for setting the bracket 2, the shaping connection component 24, and the external shaping mold 212 are correspondingly arranged on the support plate 211.

[0024] The external shaping mold 212 includes a mold mounting seat 2121 , a material stripping drive shaft 2122 inserted into the mold mounting seat 2121 , and a mold body 2123 disposed between the material stripping drive shaft 2122 and the mold mounting seat 2121 .

[0025] The mold mounting seat 2121 is in a hollow cylindrical shape, and a limiting convex edge is arranged on the outer side of the mold mounting seat 2121 to cooperate with the outer shaping mold limiting unit 213 to fix the mold mounting seat 2121 on the support plate 211.

[0026] One end of the material-removing drive shaft 2122 is inserted into the mold mounting seat 2121 and inserted into the mold main body 2123. The material-removing drive shaft 2122 is used to drive the mold main body 2123 to move axially. The end of the material-removing drive shaft 2122 facing away from the mold mounting seat 2121 is connected to the shaping unit connecting assembly 24, and the material-removing drive shaft 2122 will be described in detail in conjunction with the shaping unit connecting assembly 24.

[0027] The mold body 2123 is fixedly inserted in the mold mounting seat 2121, and the material withdrawal drive shaft 2122 is inserted in the mold body 2123. When the external shaping mold 212 is in the shaping process, the material withdrawal drive shaft 2122 is fixed in the position in the mold body 2123 and abuts against the processed casting, so that the casting is accommodated in the mold body 2123, and the material withdrawal drive shaft 2122 is limited to the position of the casting in the mold body 2123. When the shaping is completed, the material withdrawal drive shaft 2122 pushes one end of the casting to be shaped accommodated in the mold body 2123, so that the casting is separated from the mold body 2123.

[0028] The outer shaping mold limiting unit 213 includes a limiting body 2131 and a limiting ring sleeve 2132 fixedly arranged at one end of the limiting body 2131. The limiting body 2131 is fixedly connected to the support plate 211 through a nut, and the limiting ring sleeve 2132 is fixedly connected to the limiting body 2131 and clamped on the convex edge of the mold mounting seat 2121 to fix the mold mounting seat 2121 on the support plate 211.

[0029] The mandrel shaping unit 22 includes a shaping mandrel 221 fixedly connected to the shaping drive mechanism 23, and a mandrel stabilizing assembly 222 sleeved on the shaping mandrel 221. The diameter of the free end of the shaping mandrel 221 matches the diameter of the piece to be shaped, and is inserted into the piece to be shaped during shaping to shape the inner side of the belt shaping piece. The mandrel stabilizing assembly 222 is sleeved on the shaping mandrel 221 and fixedly connected to the moving plate 241 described below, so as to stabilize the shaping mandrel 221 and prevent the shaping mandrel 221 from radial displacement and thus breaking. When the mold unit 21 and the mandrel shaping unit 22 are to be shaped, the minimum distance between the shaping mandrel 221 and the mold unit 21 is greater than the height of the cast to be processed, so as to facilitate the placement of the cast into the mold unit 21.

[0030] The shaping drive mechanism 23 is disposed on the side of the core rod shaping unit 22 opposite to the die unit 21 to drive the inner shaping mechanism 23 and the die unit 21. The shaping drive mechanism 23 can be a driving device such as a cylinder.

[0031] The shaping drive mechanism 23 includes a preparatory drive cylinder 231 disposed on the bracket 2, and a shaping drive cylinder 232 fixedly disposed at one end of the preparatory drive cylinder 231. The preparatory drive cylinder 231 is used to move the shaping mandrel 221 to the entrance of the external shaping unit 21 for alignment. After alignment, the shaping drive cylinder 232 punches thereto to insert the shaping mandrel 221 into the external shaping unit 21 and into the casting, thereby performing internal shaping on the casting.

[0032] The shaping unit connection assembly 24 includes a moving plate 241 slidably connected to the bracket 2, a guide rod 242 arranged around the shaping drive cylinder 232, and an outer shaping unit connection member 243 fixedly connected to the moving plate 241 and arranged on the side of the moving plate 241 facing away from the shaping drive mechanism 23. The moving plate 241 is provided with a plurality of connection holes for installing the guide rod 242 and the shaping outer unit connection member 243. The moving plate 241 is used to set the mandrel stabilizing assembly 222. The two ends of the guide rod 242 are fixedly connected to the two ends of the shaping drive cylinder 232 respectively, and the end of the guide rod 242 away from the preparatory drive cylinder 231 is slidably connected to the moving plate 241, so that the shaping drive cylinder 232 can be lifted and slid on the moving plate 241, and the height of the shaping drive cylinder 232 can be changed. The outer shaping unit connecting member 243 includes two connecting rods 2431 fixedly disposed on the moving plate 241, and a connecting plate 2432 for connecting the connecting rods 2431 and the material stripping drive shaft 2122. The length direction of the two connecting rods 2431 is parallel to the length direction of the material stripping drive shaft 2122.

[0033] The shaping unit connecting assembly 24 connects the guide rod 242 and the outer shaping unit connecting piece 243 into a whole through the moving plate 241. When the preparatory driving cylinder 231 punches toward one side of the shaping driving cylinder 232, the preparatory driving cylinder 231 can drive the shaping driving cylinder 232, the moving plate 241, the mandrel shaping unit 22, and the outer shaping unit connecting piece 243 to move simultaneously, and the outer shaping unit connecting piece 243 drives the material withdrawal driving shaft 2122 to move, and the material withdrawal driving shaft 2122 moves in the outer shaping mold 212. Thus, the shaping unit connecting assembly 24 links the mold unit 21 and the mandrel shaping unit 22 together, so that the mold unit 21 and the mandrel shaping unit 22 can complete the stamping shaping work by sharing a set of driving equipment.

[0034] The pickup unit 30 includes a mounting frame 31 fixedly arranged on the support plate 211, a horizontal driving device 32 fixedly arranged on the mounting frame 31, a vertical driving device 33 arranged on the horizontal driving device 32, and a pickup clamp 34 arranged on the vertical driving device 33. The length direction of the mounting frame 31 is perpendicular to the length direction of the transmission mechanism 10. The horizontal moving device 32 and the vertical moving device 33 can both be driving parts such as screw rods or cylinders. The horizontal driving device 31 is arranged along the length direction of the mounting frame 31 to drive the pickup clamp 34 to reciprocate in the horizontal direction. The vertical driving device 33 is used to drive the pickup clamp 34 to move back and forth in the vertical direction. The clamping part of the pickup clamp 34 is aligned with the mold unit 21, that is, the central axis of the clamped casting to be processed is on the same straight line as the central axis of the mold unit 21. When the pick-up gripper 34 grabs the casting, the vertical drive device 33 drives the pick-up gripper 34 to move up and down in the vertical direction so that the casting is higher than the mold unit 21, and the horizontal drive device 32 drives the pick-up gripper 34 to move along the line connecting the central axis of the casting and the mold unit 21. When the central axis of the casting coincides with the central axis of the mold unit 21, the pick-up gripper 34 releases the casting and drops it into the external shaping mold 212. After the casting is processed by the shaping mechanism 20, the pick-up gripper 34 moves here to take it out.

[0035] In summary, when the shaping machine is in operation, the transmission mechanism 10 first transports the casting to be processed to the pickup unit 30, and the pickup unit 30 places the casting in the outer shaping mold 212 through the pickup clamp 34. The preparatory drive cylinder 231 drives the core rod shaping unit 22 to move downward so that the shaping core rod 221 is aligned with the casting. The shaping drive cylinder 232 drives the core rod shaping unit 22 to punch downward and cooperate with the outer shaping mold 212 to complete the shaping of the casting. After the shaping is completed, the shaping drive cylinder 232 moves upward, driving the material withdrawal drive shaft 2122 to move upward, thereby pushing one end of the casting out of the outer shaping mold 212 to facilitate the removal of the shaped casting. Finally, the pickup unit 30 moves here to take out the casting, forming a complete shaping cycle.

[0036] Compared with the prior art, the utility model provides a single-side driven shaping machine for castings, which includes a transmission mechanism 10, a shaping mechanism 20, and a pickup unit 30. The shaping mechanism 20 includes a mold unit 21 arranged on the bracket 2, a core rod shaping unit 22 arranged on the bracket 2 and corresponding to the mold unit 21, a shaping drive mechanism 23 arranged at one end of the core rod shaping unit 22, and a shaping unit connecting assembly 24 arranged on the bracket 2 and used to connect the mold unit 21, the core rod shaping unit 22, and the shaping drive mechanism 23. Since the shaping unit connecting assembly 24 forms a linkage between the mold unit 21 and the core rod shaping unit 22, the single-side driven shaping machine for castings only needs to set the shaping drive mechanism 23 on one side of the core rod shaping unit 22 to simultaneously drive the mold unit 21 and the core rod shaping unit 22 to perform shaping and material removal procedures.
