Description

Technical Field

[0001] This invention relates to the field of automotive parts manufacturing equipment technology, specifically to a fully automatic desprue machine for automotive steering wheel die castings. Background Technology

[0002] Automotive steering wheel die castings are mostly made of aluminum alloy using high-pressure die casting technology. Due to the complex overall structure and irregular shape of the steering wheel, and the thin-walled annular structure of the outer ring, die casting is difficult. If the pouring and feeding layout is not reasonable, casting defects such as insufficient material, porosity, cold shuts, and shrinkage porosity can easily occur during the casting process. Therefore, existing die casting processes generally adopt a composite feeding design with one main gate and multiple auxiliary gates. The main gate is mainly responsible for supplying material to the central area of ​​the steering wheel body, ensuring the complete formation of core structures such as the central hub and mounting plate. The auxiliary gates are evenly distributed and mainly fill the thin-walled outer ring of the steering wheel body to ensure the annular shape. After the die-cast blank cools and solidifies, the main gate and auxiliary gates are both redundant and waste structures that must be completely removed before subsequent finishing to meet the requirements of assembly, coating, and safe use. At present, the industry has a relatively mature process for removing the main gate. It is common to use a special punching die in conjunction with a press. The punching die is fixed on the press table, and the die-cast blank of the steering wheel is positioned inside the punching die. The main gate is punched off and separated by the downward pressure of the press. After the main gate is punched off, the auxiliary gates distributed on the outer ring of the disc still need to be specially removed.

[0003] Existing technologies have disclosed related auxiliary gate removal equipment, such as the fully automatic gate removal machine for steering wheel die castings disclosed in CN206578268U. This device mainly relies on a workpiece positioning rotary table in conjunction with a vertical clamping device to complete the clamping and basic positioning of the steering wheel body, and drives the steering wheel body to perform step-by-step rotational motion along its own central axis. During the intermittent rotation of the workpiece, an independent gate removal mechanism arranged outside the workpiece positioning rotary table is used to remove the auxiliary gates on the wheel body one by one. However, this existing equipment has obvious technical defects: First, it requires the addition of a workpiece rotation transmission mechanism to realize the step-by-step rotation of the steering wheel. The whole machine has many transmission parts, a bulky and complex structure, high equipment manufacturing costs, and is prone to rotation jamming, positioning deviation and other faults under long-term mass production conditions, making subsequent inspection and maintenance difficult; Second, The workpiece relies solely on a single vertical clamping device for axial positioning, lacking a matching radial support and positioning structure. During the punching process of the auxiliary gate, the workpiece is easily affected by shearing vibration, causing it to shift and wobble, which in turn leads to quality problems such as casting deformation, skewed cuts, and thin-walled disc cracking. Thirdly, the multiple sets of gate removal mechanisms on the outer periphery require multiple independent power sources for separate driving, resulting in a dispersed power layout, high energy consumption, and poor synchronization of the actions of each mechanism. Fourthly, the four evenly distributed auxiliary gates are processed by step-by-step punching, which cannot achieve synchronous shearing. A single punching easily generates unilateral tensile stress on the annular disc, exacerbating casting deformation. Furthermore, the operation cycle is lengthy and the processing efficiency is low, making it difficult to meet the needs of large-scale, high-precision mass production of steering wheel die castings.

[0004] Therefore, there is an urgent need to develop a specialized gate removal equipment with a simplified structure, reliable positioning, single-power linkage, and simultaneous punching of multiple gates, in order to solve the industry pain points of insufficient positioning, asynchronous action, complex structure, and low yield in the secondary gate removal process of existing technologies. Summary of the Invention

[0005] The purpose of this invention is to provide a fully automatic de-gate machine for automotive steering wheel die castings to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automatic de-sprue machine for die-cast automotive steering wheels, comprising a worktable and a dual-function assembly. Four dual-function assemblies are concentrically arrayed on the worktable. Each dual-function assembly includes a guide rail fixedly mounted on the worktable. A support is fixedly mounted at the end of the guide rail, and a linear bearing is embedded in the middle of the support. A connecting rod is axially slidably mounted inside the linear bearing, and trunnions are fixedly connected to both ends of the rear end of the connecting rod. A sliding block is fixedly connected to the front end of the connecting rod, and the sliding block is slidably mounted on the guide rail. A punching head is fixedly mounted at the bottom of the recess of the sliding block, and an abutment block is movably mounted at the top of the recess of the sliding block. The outer periphery of the abutment block is limited and engaged with a pre-set groove on the end face of the punching head by a pin, and the end of the abutment block is elastically connected to the side wall of the recess of the sliding block by a spring.

[0007] Furthermore, a back plate is fixedly installed on the back of the workbench, and a controller is installed on the side of the back plate via a bracket.

[0008] Furthermore, a press is bolted to the top of the back plate, and a clamping block is fixedly connected to the telescopic end of the press.

[0009] Furthermore, a pre-positioning component is fixedly installed on the workbench. The pre-positioning component includes a waste discharge ring fixedly installed on the workbench. The bottom of the waste discharge ring is provided with an inward-outward inclined surface, and the opening of the waste discharge ring is located on the inner end face facing the punching head. The outer end face of the waste discharge ring is provided with a discharge outlet, and a guide plate is inclinedly connected to the outside of the discharge outlet.

[0010] Furthermore, the prepositioning component also includes a support ring fixedly installed above the outer side of the waste discharge ring. The support ring has an opening at the top and four notches recessed at the bottom, with the notches corresponding to the punching positions of the punching head.

[0011] Furthermore, a disc frame is placed inside the support ring, and the inner ring of the disc frame is radially supported by abutment blocks. Four secondary gates are evenly spaced at the bottom edge of the outer edge of the disc frame, and the two adjacent secondary gates are at a 90-degree angle. The position of the secondary gates corresponds to the position of the four notches at the bottom of the support ring. When the punching head moves outward, the secondary gates are punched and fall into the waste discharge ring below.

[0012] Furthermore, the inner ring of the disc frame is fixed with connecting ribs, and the end of the connecting rib facing away from the disc frame is fixedly connected to the steering column mounting plate. The steering column mounting plate has a through hole in the middle for subsequent assembly of the car steering column.

[0013] Furthermore, a clamping drive assembly is fixedly installed in the middle of the workbench. The clamping drive assembly includes a column fixedly installed in the middle of the workbench. Four side slots are concentrically arrayed on the outer periphery of the bottom end of the column, and a cross block is vertically raised and lowered inside the side slots.

[0014] Furthermore, the clamping drive assembly also includes a groove plate fixedly installed at the bottom of the cross block. The inclined sliding groove inside the groove plate slides in conjunction with the trunnions on both sides of the rear end of the connecting rod. The vertical lifting of the cross block in the side groove is converted into the horizontal movement of the connecting rod by the sliding of the trunnions in the inclined sliding groove of the groove plate.

[0015] Furthermore, the clamping drive assembly also includes a second spring installed at the bottom of the cross block. A trigger rod is fixedly connected to the top of the cross block, and the axis of the trigger rod coincides with the axis of the column cavity. An elastic shoulder pad is installed at the top of the trigger rod, and the elastic shoulder pad is in close contact with the clamping block at the telescopic end of the press. While the clamping block achieves axial clamping of the steering column mounting plate through the elastic shoulder pad, it also drives the cross block to move vertically up and down simultaneously through the trigger rod.

[0016] This invention provides a fully automatic de-gate removal machine for automotive steering wheel die castings, which has the following beneficial effects; 1. This application innovatively integrates radial contact positioning and gate punching functions into a dual-function component, realizing an orderly linkage operation process of stabilizing the part first and then punching. At the same time, through the synchronous cooperation of four dual-function components in a concentric array on the worktable, the four auxiliary gates of the steering wheel die casting are evenly distributed at a 90-degree angle and are cut off at one time. Compared with the traditional method of punching in stages and manual cutting, the operation cycle of a single workpiece is greatly shortened, the gate removal operation efficiency is effectively improved, and it is fully adapted to the mass production needs of steering wheel die castings.

[0017] 2. This application sets up a clamping drive component, which relies on the axial clamping power of the press to simultaneously drive the slider horizontally. By using the cooperative structure of the cross block, slot plate and connecting rod, the vertical axial movement of the press is accurately converted into the horizontal radial movement of the slider. The linkage operation of axial clamping and slider horizontal drive can be completed without the need for additional independent drive components, which simplifies the structure of the equipment power system and reduces the equipment manufacturing cost and subsequent failure rate.

[0018] 3. This application achieves precise pre-positioning of the steering wheel die-casting part by setting up a pre-positioning component and using a support ring to ensure that the four auxiliary gates of the workpiece correspond precisely to the bottom notch of the support ring and the position of the punching head. At the same time, with the waste discharge ring with a slope and the guide plate, the waste material from the auxiliary gates that is punched off can be automatically guided along the slope of the waste discharge ring and flow into the guide plate through the discharge outlet for centralized collection. There is no need for manual additional cleaning of waste material, which avoids the waste material blocking the continuous operation of the equipment and realizes an unmanned and automated continuous production mode.

[0019] 4. This application adopts a single power source drive design. With only the press as the sole power source, the three core actions of axial clamping, radial clamping, and synchronous punching can be realized simultaneously. Before the punching operation at the secondary gate, the steering wheel die casting is first subjected to the axial pressure of the top clamping block and the radial clamping force of the slider, which limits and fixes it. During the punching process, the workpiece will not move or deviate. This fundamentally avoids the problems of workpiece deformation and skewed cut caused by unstable workpiece positioning in traditional punching, and ensures the structural accuracy and quality stability of the steering wheel die casting as a core safety component of automobiles.

[0022] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention. Please see Figures 6 to 7This invention provides a technical solution: a fully automatic de-sprue machine for die-cast automotive steering wheels, comprising a worktable 1 and a dual-function component 2. Four dual-function components 2 are concentrically arrayed on the worktable 1. Each dual-function component 2 includes a guide rail 201 fixedly mounted on the worktable 1, a support 202 fixedly mounted at the end of the guide rail 201, and a linear bearing 203 embedded in the middle of the support 202. A connecting rod 204 is axially slidably mounted inside the linear bearing 203, and the connecting rod 204 is further... A trunnion 205 is fixedly connected to both ends of the connecting rod 204. A sliding block 206 is fixedly connected to the front end of the connecting rod 204. The sliding block 206 is slidably mounted on the guide rail 201. A punching head 207 is fixedly mounted at the bottom end of the recess of the sliding block 206. An abutment block 208 is movably mounted at the top end of the recess of the sliding block 206. The outer periphery of the abutment block 208 is limited and matched with the pre-set groove on the end face of the punching head 207 by a pin. The end of the abutment block 208 is elastically connected to the side wall of the recess of the sliding block 206 by a spring 209. The specific operation is as follows: After the abutment block 208 completes radial stabilization support, the sliding block 206 continues to feed outward. The punching head 207 at the bottom of the notch of the sliding block 206 simultaneously passes through the notch 705 set in the support ring 704, and accurately performs synchronous lateral shearing on the four secondary gates 9 evenly distributed at ninety degrees. The four sets of dual-function components 2 work together to complete the cutting and separation of all secondary gates 9 in one go. This application innovatively integrates radial abutment positioning and gate punching function into dual-function component 2 to realize the orderly linkage operation process of stabilizing the part first and then punching. At the same time, through the synchronous cooperation of the four dual-function components 2 in the concentric array of the worktable 1, the four secondary gates 9 evenly distributed at ninety degrees on the steering wheel die casting are cut off at one time. Compared with the traditional method of punching in stages and manual cutting, the operation cycle of a single workpiece is greatly shortened, the gate removal operation efficiency is effectively improved, and it is fully adapted to the mass production needs of steering wheel die castings. Please see Figures 1 to 4A back plate 3 is fixedly installed on the back of the workbench 1, and a controller 4 is installed on the side of the back plate 3 via a bracket. A press 5 is bolted to the top of the back plate 3, and a clamping block 6 is fixedly connected to the telescopic end of the press 5. A pre-positioning component 7 is fixedly installed on the workbench 1. The pre-positioning component 7 includes a waste discharge ring 701 fixedly installed on the workbench 1. The bottom of the waste discharge ring 701 has an inward-outward inclined surface, and the opening of the waste discharge ring 701 is located on the inner end face facing the punching head 207. The outer end face of the waste discharge ring 701 has a discharge outlet 702, and a guide plate 703 is inclinedly connected to the outside of the discharge outlet 702. The pre-positioning component 7 also includes a support ring 704 fixedly installed above the outer side of the waste discharge ring 701. The opening of the support ring 704 is located at the top, and the bottom of the support ring 704 has four recessed openings. There is a notch 705, and the position of the notch 705 corresponds to the punching position of the punching head 207. The disc frame 8 is placed inside the support ring 704, and the inner ring of the disc frame 8 is radially supported by the abutment block 208. Four auxiliary gates 9 are evenly spaced at the bottom of the outer edge of the disc frame 8, and the two adjacent auxiliary gates 9 are at a 90-degree angle. The position of the auxiliary gates 9 corresponds to the position of the four notches 705 at the bottom of the support ring 704. When the punching head 207 moves outward, the auxiliary gates 9 are punched and fall into the waste discharge ring 701 below. The inner ring of the disc frame 8 is fixed with connecting ribs 10, and the end of the connecting ribs 10 away from the disc frame 8 is fixedly connected to the steering column mounting plate 11. The steering column mounting plate 11 has a through hole in the middle for subsequent assembly of the car steering column. The specific operation is as follows: the die-cast steering wheel frame 8 is placed on the support ring 704 of the pre-positioning component 7. The four secondary gates 9, which are evenly spaced at 90-degree angles on the outer edge of the frame 8, are precisely embedded into the four corresponding notches 705 at the bottom of the support ring 704, completing the initial positioning of the casting. At this time, the steering column mounting plate 11 is located directly below the clamping block 6. The entire machine is ready for feeding. The waste material from the secondary gates 9 that has been punched off falls directly into the lower waste discharge ring 701. Relying on the inclined structure from the inside to the outside at the bottom of the waste discharge ring 701, the waste material slides down the inclined surface and flows into the guide plate 703 through the discharge outlet 702, automatically... To prevent waste from accumulating and jamming, this application uses a pre-positioning component 7 and a support ring 704 to accurately position the steering wheel die casting. This ensures that the four auxiliary gates 9 of the workpiece correspond precisely to the bottom notch 705 of the support ring 704 and the position of the punching head 207. At the same time, with the inclined waste discharge ring 701 and the guide plate 703, the waste from the punched auxiliary gates 9 can be automatically guided along the inclined surface of the waste discharge ring 701 and flow into the guide plate 703 through the discharge outlet 702 for centralized collection. No manual cleaning of waste is required, which avoids waste jamming and affecting the continuous operation of the equipment, and realizes an unmanned and automated continuous production mode. Please see Figures 5 to 6A clamping drive assembly 12 is fixedly installed in the middle of the workbench 1. The clamping drive assembly 12 includes a column 1201 fixedly installed in the middle of the workbench 1. Four side slots 1202 are concentrically arrayed on the outer periphery of the bottom end of the column 1201. A cross block 1203 is vertically raised and lowered inside the side slots 1202. The clamping drive assembly 12 also includes a groove plate 1204 fixedly installed on the bottom of the four sides of the cross block 1203. The inclined sliding groove provided inside the groove plate 1204 slides with the trunnions 205 on both sides of the rear end of the connecting rod 204. The vertical raising and lowering of the cross block 1203 in the side slots 1202 is achieved by the inclined sliding groove provided by the trunnions 205 in the groove plate 1204. The sliding within the inclined groove is converted into the horizontal movement of the connecting rod 204. The pressing drive assembly 12 also includes a spring 1205 installed at the bottom of the cross block 1203. A trigger rod 1206 is fixedly connected to the top of the cross block 1203, and the axis of the trigger rod 1206 coincides with the axis of the column 1201 cavity. An elastic shoulder pad 1207 is installed at the top of the trigger rod 1206, and the elastic shoulder pad 1207 is in close contact with the pressing block 6 at the telescopic end of the press 5. While the pressing block 6 axially presses the steering column mounting plate 11 through the elastic shoulder pad 1207, it also drives the cross block 1203 to move vertically up and down simultaneously through the trigger rod 1206. The specific operation is as follows: the press 5 drives the clamping block 6 at the telescopic end to move downward. The clamping block 6 first fits against the elastic shoulder pad 1207, which on the one hand achieves axial clamping and fixing of the steering column mounting plate 11 of the steering wheel die casting, completely locking the vertical movement freedom of the casting. On the other hand, the elastic shoulder pad 1207 presses down the trigger rod 1206, which drives the cross block 1203 in the clamping drive assembly 12 to move vertically downward synchronously along the side groove 1202 of the column 1201. When the cross block 1203 moves downward, the inclined sliding groove inside the groove plate 1204 around it forms a sliding fit with the trunnion 205 at the rear end of the connecting rod 204, converting the vertical downward movement of the cross block 1203 into the horizontal outward linear movement of the connecting rod 204 along the linear bearing 203. The sliding block 206 is driven to slide outward along the guide rail 201. The abutment block 208 on the sliding block 206 first fits against the inner ring of the disc frame 8, and with the spring 209, it achieves flexible elastic clamping, completing the full circumferential radial support limit of the casting, eliminating vibration offset during punching operations. This application sets up a clamping drive assembly 12, relying on the axial clamping power of the press 5 to simultaneously achieve horizontal drive of the slider. By utilizing the cooperation structure of the cross block 1203, the slot plate 1204 and the connecting rod 204, the vertical axial movement of the press 5 is accurately converted into the horizontal radial movement of the slider. The linkage operation of axial clamping and horizontal drive of the slider can be completed without additional independent drive components, simplifying the structure of the equipment power system and reducing the equipment manufacturing cost and subsequent failure rate.

[0023] In summary, when using this fully automatic de-gate machine for automotive steering wheel die castings: Workpiece pre-positioning and loading stage: The disc frame 8 of the automotive steering wheel die casting is placed on the support ring 704 of the pre-positioning component 7. The four auxiliary gates 9, which are equally spaced at ninety degrees on the outer edge of the disc frame 8, are precisely embedded in the four corresponding notches 705 at the bottom of the support ring 704, completing the initial positioning of the casting. At this time, the steering column mounting plate 11 is located directly below the clamping block 6, and the whole machine is ready for loading. Axial clamping and locking stage: Press 5 drives the clamping block 6 at the telescopic end to move downward. The clamping block 6 first fits against the elastic shoulder pad 1207. On the one hand, it achieves axial clamping and fixing of the steering column mounting plate 11 of the steering wheel die casting, completely locking the freedom of the casting to move up and down. On the other hand, the elastic shoulder pad 1207 presses down the trigger rod 1206, driving the cross block 1203 in the clamping drive assembly 12 to move vertically downward synchronously along the side groove 1202 of the column 1201. During the power reversal and radial support positioning stage: When the cross block 1203 moves downward, the inclined sliding groove inside the surrounding groove plate 1204 forms a sliding engagement with the trunnion 205 at the rear end of the connecting rod 204, converting the vertical downward movement of the cross block 1203 into the horizontal outward linear movement of the connecting rod 204 along the linear bearing 203. The connecting rod 204 drives the sliding block 206 to slide outward along the guide rail 201. The abutment block 208 on the sliding block 206 first fits against the inner ring of the disc frame 8, and with the help of the spring 209, achieves flexible elastic clamping, completing the full circumference of the casting. Radial support limit eliminates vibration offset during punching operations. This application sets up a clamping drive assembly 12, which relies on the axial clamping power of the press 5 to simultaneously drive the slider horizontally. By utilizing the cooperation structure of the cross block 1203, the slot plate 1204 and the connecting rod 204, the vertical axial movement of the press 5 is accurately converted into the horizontal radial movement of the slider. The linkage operation of axial clamping and slider horizontal drive can be completed without additional independent drive components, which simplifies the structure of the equipment power system and reduces the equipment manufacturing cost and subsequent failure rate. Four-point synchronous punching and gate removal stage: After the abutment block 208 completes radial stabilization support, the sliding block 206 continues to feed outward. The punching head 207 at the bottom of the notch of the sliding block 206 simultaneously passes through the notch 705 set in the support ring 704, and accurately performs synchronous lateral shearing on the four sub-gates 9 evenly distributed at ninety degrees. The four sets of dual-function components 2 work together to complete the cutting and separation of all sub-gates 9 in one go. This application innovatively integrates radial abutment positioning and gate punching functions into dual-function components 2 to realize an orderly linkage operation process of stabilizing the part first and then punching. At the same time, through the synchronous cooperation of the four dual-function components 2 in the concentric array of the worktable 1, the four sub-gates 9 evenly distributed at ninety degrees on the steering wheel die casting are cut off at one time. Compared with the traditional step-by-step punching and manual cutting method, the operation cycle of a single workpiece is greatly shortened, the gate removal operation efficiency is effectively improved, and it is fully adapted to the mass production needs of steering wheel die castings. Automatic waste discharge and diversion stage: The waste material from the secondary gate 9 that has been punched off falls directly into the lower waste discharge ring 701. Relying on the inclined structure from the inside to the outside at the bottom of the waste discharge ring 701, the waste material slides down the inclined surface and flows into the guide plate 703 through the discharge outlet 702, automatically diverting and collecting it outwards, avoiding waste accumulation and jamming. This application sets up a pre-positioning component 7 and uses the support ring 704 to achieve precise pre-positioning of the steering wheel die casting, ensuring that the four secondary gates 9 of the workpiece correspond precisely to the bottom notch 705 of the support ring 704 and the position of the punching head 207. At the same time, with the inclined waste discharge ring 701 and the guide plate 703, the waste material from the secondary gate 9 that has been punched off can be automatically diverted along the inclined surface of the waste discharge ring 701 and flows into the guide plate 703 through the discharge outlet 702 for centralized collection. There is no need for manual cleaning of waste material, avoiding waste jamming that affects the continuous operation of the equipment, and realizing an unmanned and automated continuous production mode. Mechanism reset and cycle operation stage: After a single punching operation, the press 5 drives the clamping block 6 to move upward and reset. The cross block 1203 returns to its original position under the elastic force of the spring 1205. Through the linkage between the slot plate 1204 and the trunnion 205, the connecting rod 204 and the sliding block 206 move inward synchronously. The abutment block 208 releases the radial support of the inner ring of the disc frame 8, and the finished casting can be taken out. After the whole machine is reset, it enters the next round of fully automatic operation cycle. The entire equipment is uniformly controlled and operated by the controller 4. This application adopts a single power source. The drive design, using only the press 5 as a single power source, can simultaneously achieve three core actions: axial clamping, radial clamping, and synchronous punching. Before the punching operation at the secondary gate 9, the steering wheel die casting is first subject to dual limiting and fixing by the axial pressure of the top clamping block 6 and the radial clamping force of the slider. During the punching process, the workpiece will not move or shift, fundamentally avoiding the problems of workpiece deformation and skewed cuts caused by unstable workpiece positioning in traditional punching. This ensures the structural accuracy and quality stability of the steering wheel die casting as a core safety component of automobiles.
