Description

Technical Field

[0001] This invention relates to the field of wheel processing technology, and more specifically to a wheel cover vacuum forming device. Background Technology

[0002] Existing wheel cover vacuum forming equipment lacks a tensioning device for the plastic fabric during wheel cover production. As a result, relative displacement occurs between the plastic fabric and the vacuum forming mold during the vacuum forming process, which affects the vacuum forming effect and prevents the formation of a complete wheel cover.

[0003] When making wheel covers, existing vacuum forming equipment lacks a winding device, which prevents continuous vacuum forming and reduces its production efficiency. At the same time, because the plastic fabric is not softened during the vacuum forming process, the plastic fabric and the vacuum forming mold cannot fit tightly. When vacuum forming, a large suction force is required to perform vacuum forming, which reduces its production efficiency.

[0004] Therefore, it is necessary to invent a vacuum forming device for wheel covers. Summary of the Invention

[0005] To address this issue, the present invention provides a wheel cover vacuum forming device. By using a pressing component to press the plastic fabric tightly, and a softening component to soften and deform the plastic fabric, a geared motor is driven to make the softened plastic fabric fit tightly with the wheel mold. At the same time, a forming device is used to form a wheel cover that meets the requirements, thereby solving the problems of poor vacuum forming effect and low vacuum forming efficiency of existing vacuum forming devices.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a wheel cover vacuum forming device, comprising an adjustment device and a forming device, wherein the adjustment device is located at the top of the forming device and is connected to the forming device, the adjustment device includes a pressing component, wherein two sets of the pressing component are provided and are respectively located on both sides of the forming device, and the top of the two sets of pressing components are provided with a softening component;

[0007] The clamping component includes a side frame, two sets of push blocks are fixedly installed on the top outer wall of the side frame, circular sleeves are fixedly installed at both ends of the side frame, two sets of cylinders are fixedly installed on the outer side wall of the side frame, the two sets of cylinders are respectively located at the bottom of the two sets of push blocks and the output shaft slides through the bottom of the push blocks, and two sets of lifting components are provided on the outer side wall of the side frame.

[0008] The softening component includes a square frame two. Both sides of the square frame two have L-shaped slots at the bottom. The two sets of L-shaped slots are respectively engaged with the inner walls of the two sets of side frames, and both sides of the square frame two are respectively fixedly connected to the outer walls of the four sets of push blocks. A square sealing groove is provided at the top of the square frame two.

[0009] The softening component also includes a square frame, the bottom of which is fixedly connected to four sets of cylinder output shafts on both sides. Sealing boxes are fixedly installed on both sides of the top of the square frame. The bottom of the sealing box has an oblique air outlet, the angle between the oblique air outlet and the plane is 45 degrees. Three sets of micro fans are fixedly connected to the top of the sealing box. Heating wires are provided inside the sealing box. Square ribs are fixedly installed at the bottom of the square frame, and the square ribs are used in conjunction with the square sealing groove.

[0010] Preferably, the inner walls of the two sets of circular sleeves on the same side are rotatably connected to the same roller, and the outer walls of the two sets of circular sleeves on the far right are fixedly installed with servo motors, the output shaft of the servo motors being fixedly connected to the rollers located inside the circular sleeves.

[0011] Preferably, the molding device includes a hollow base, with two sets of exhaust holes on one side of the hollow base, and two sets of wheel molds fixedly installed on the top of the hollow base. The outer walls of the top of the two sets of wheel molds each have multiple sets of suction holes arranged in a circumferential array, and the multiple sets of suction holes are connected to the interior of the hollow base.

[0012] Preferably, the lifting assembly includes a base, the bottom of which is fixedly connected to the side wall of the hollow base, and two sets of sliding plates are fixedly installed on the top of the base. A rack is fixedly installed on the outer side wall of the sliding plate on the right side.

[0013] The lifting assembly also includes a bridge frame, the outer wall of which is fixedly connected to the outer wall of the side frame. Two sets of slide rails are fixedly installed at the bottom of the bridge frame. Each set of slide rails has insertion holes at its bottom. Both sets of insertion holes pass through the slide rails and the bridge frame. Two sets of sliding plates are slidably connected to the two sets of insertion holes respectively. A reduction motor is fixedly installed on the inner wall of the bridge frame. A matching gear is fixedly installed on the output shaft of the reduction motor. The matching gear works in conjunction with the rack.

[0014] The beneficial effects of this invention are:

[0015] 1. Pass the plastic fabric to be vacuum-formed sequentially through the left roller, the gap between square frame two and square frame one, and the right roller. Start two sets of servo motors, making them rotate in opposite directions. The output shafts of the servo motors drive the rollers to rotate in opposite directions. At this time, the two sets of rollers can tighten the plastic fabric between square frame two and square frame one. After tightening the plastic fabric, drive four sets of cylinders, making the output shafts of the four sets of cylinders drive square frame one to move downwards, so that the square ribs on square frame one cooperate with the square sealing grooves on square frame two, thereby clamping the plastic fabric between square frame two and square frame one. Then, energize the two sets of heating wires to release heat, and at the same time drive the micro fan to blow air into the sealed box. The airflow can carry the heat emitted by the heating wires out from the oblique air outlet, thereby heating the plastic fabric between square frame two and square frame one and softening it.

[0016] 2. After the plastic fabric softens, the geared motor is driven, causing the output shaft of the geared motor to rotate and engage with the rack on the sliding plate. This causes the bridge frame to move the two side frames, which in turn cause the square frame two, which is fixedly connected to the side frames, to move the plastic fabric downwards. When the square frame two moves to engage with the hollow base, the softened plastic fabric is tightly adhered to the top of the hollow base. At this point, by connecting the air pump to the exhaust port, the air pump is started to extract the gas inside the hollow base. This reduces the internal pressure of the hollow base, allowing the air pump to extract the gas between the plastic fabric and the top of the hollow base through the suction port. The pressure between the hollow base and the softened plastic fabric decreases, and under the action of external air pressure, the softened plastic fabric will tightly adhere to the surface of the wheel mold. After the plastic fabric cools, it forms a wheel cover that meets the requirements. After completion, the servo motor on the right side is driven to rewind the wheel cover, and the next wheel cover is made simultaneously. Attached Figure Description

Detailed Implementation

[0029] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0030] See attached document Figure 1-11 The present invention provides a wheel cover vacuum forming device, including a control device 100 and a forming device 200. The control device 100 is located on top of the forming device 200 and connected to the forming device 200. The control device 100 includes a pressing member 130. The pressing member 130 is provided in two sets and is located on both sides of the forming device 200 respectively. The top of the two sets of pressing members 130 is provided with a softening component 110.

[0031] The clamping component 130 includes a side frame 131. Two sets of push blocks 132 are fixedly installed on the top outer wall of the side frame 131. Circular sleeves 133 are fixedly installed at both ends of the side frame 131. Two sets of cylinders 134 are fixedly installed on the outer wall of the side frame 131. The two sets of cylinders 134 are located at the bottom of the two sets of push blocks 132, and their output shafts slide through the bottom of the push blocks 132. Two sets of lifting components 140 are provided on the outer wall of the side frame 131. Specifically, the plastic fabric to be vacuum-formed is sequentially passed through the left roller 160, the gap between the second square frame 120 and the first square frame 111, and the right roller 160. Two sets of servo motors 135 rotate in opposite directions. The output shafts of the servo motors 135 drive the rollers 160 to rotate in opposite directions. At this time, the two sets of rollers 160 can tighten the plastic fabric between the second square frame 120 and the first square frame 111. After tightening the plastic fabric, four sets of cylinders 134 are driven, and the output shafts of the four sets of cylinders 134 drive the first square frame 111 to move downward, so that the square ribs 116 on the first square frame 111 cooperate with the square sealing grooves 121 on the second square frame 120, thereby clamping the plastic fabric between the second square frame 120 and the first square frame 111.

[0032] The softening component 110 includes a square frame 120. L-shaped slots 122 are provided on the bottom of both sides of the square frame 120. The two sets of L-shaped slots 122 are respectively engaged with the inner walls of the two sets of side frames 131, and the two sides of the square frame 120 are respectively fixedly connected to the outer walls of the four sets of push blocks 132. A square sealing groove 121 is provided on the top of the square frame 120.

[0033] The softening component 110 also includes a square frame 111. The bottom sides of the square frame 111 are fixedly connected to the output shafts of four sets of cylinders 134. Sealing boxes 112 are fixedly installed on both sides of the top of the square frame 111. The bottom of the sealing box 112 has an angled air outlet 113, which forms a 45-degree angle with the plane. The 45-degree angle of the air outlet 113 allows hot air to be blown onto the plastic fabric. Three sets of miniature fans 115 are fixedly connected to the top of the sealing box 112. Inside the sealing box 112... A heating wire 114 is provided, and a square rib 116 is fixedly installed at the bottom of the square frame 111. The square rib 116 is used in conjunction with the square sealing groove 121. Specifically, the two sets of heating wires 114 are energized to release heat, and at the same time, a micro fan 115 is driven to blow air into the sealing box 112. The airflow can carry the heat emitted by the heating wires 114 out through the oblique air outlet 113, thereby heating the plastic cloth between the square frame 2 120 and the square frame 111 and softening it.

[0034] Furthermore, the inner walls of the two sets of circular sleeves 133 located on the same side are rotatably connected to the same roller 160, and the outer walls of the two sets of circular sleeves 133 located on the far right are fixedly installed with servo motors 135, and the output shaft of the servo motors 135 is fixedly connected to the roller 160 located inside the circular sleeves 133.

[0035] Furthermore, the molding device 200 includes a hollow base 210. Two sets of exhaust holes 211 are provided on one side of the hollow base 210. Two sets of wheel molds 220 are fixedly installed on the top of the hollow base 210. Multiple sets of suction holes 221 arranged in a circumferential array are provided on the outer wall of the top of each set of wheel molds 220. All suction holes 221 communicate with the interior of the hollow base 210. Specifically, by connecting an air pump to the exhaust holes 211 and simultaneously activating the air pump to extract gas from inside the hollow base 210, the hollow base... As the internal pressure of the base 210 decreases, the hollow base 210 can draw gas from the top of the plastic cloth through the suction hole 221. At this time, the pressure between the hollow base 210 and the softened plastic cloth decreases. Under the action of external air pressure, the softened plastic cloth will tightly adhere to the surface of the wheel mold 220. After the plastic cloth cools down, it can form a wheel cover that meets the requirements. After the production is completed, the servo motor 135 on the right side can be driven to roll up the wheel cover and make the next wheel cover at the same time.

[0036] Furthermore, the lifting assembly 140 includes a base 141, the bottom of which is fixedly connected to the side wall of the hollow base 210, and two sets of sliding plates 142 are fixedly installed on the top of the base 141. A rack 143 is fixedly installed on the outer side wall of the sliding plate 142 on the right side.

[0037] The lifting assembly 140 also includes a bridge frame 150. The outer wall of the bridge frame 150 is fixedly connected to the outer wall of the side frame 131. Two sets of slide rails 151 are fixedly installed at the bottom of the bridge frame 150. Each set of slide rails 151 has a receiving hole 152 at its bottom, and both sets of receiving holes 152 pass through the slide rails 151 and the bridge frame 150. Two sets of sliding plates 142 are slidably connected to the two sets of receiving holes 152 respectively. A reduction motor 153 is fixedly installed on the inner wall of the bridge frame 150. A mating gear 154 is fixedly installed on the output shaft of the reduction motor 153. In conjunction with rack 143, specifically, it drives geared motor 153, causing the output shaft of geared motor 153 to drive mating gear 154 to rotate, thereby meshing with rack 143 on sliding plate 142, causing bridge frame 150 to drive two side frames 131 to move, thereby causing square frame two 120 and square frame one 111, which are fixedly connected to side frame 131, to move plastic cloth downward. When square frame two 120 moves to engage with hollow base 210, the softened plastic cloth is tightly attached to the top of hollow base 210.

[0038] The process of using this invention is as follows: Those skilled in the art will pass the plastic fabric to be vacuum-formed sequentially through the left roller 160, the gap between the second square frame 120 and the first square frame 111, and the right roller 160. By activating two sets of servo motors 135, the two sets of servo motors 135 rotate in opposite directions. The output shafts of the servo motors 135 drive the rollers 160 to rotate in opposite directions. At this time, the two sets of rollers 160 can tighten the plastic fabric between the second square frame 120 and the first square frame 111. After tightening the plastic fabric, four sets of cylinders 134 are driven, causing the output shafts of the four sets of cylinders 134 to drive the... The square frame 111 moves downward, causing the square ribs 116 on the square frame 111 to engage with the square sealing groove 121 on the square frame 120, thereby clamping the plastic cloth between the square frame 120 and the square frame 111. Then, the two sets of heating wires 114 are energized to release heat, and at the same time, the micro fan 115 is driven to blow air into the sealing box 112. The airflow can carry the heat emitted by the heating wires 114 out through the oblique air outlet 113, thereby heating the plastic cloth between the square frame 120 and the square frame 111 and softening it.

[0039] When the plastic fabric softens, the drive motor 153 is activated, causing its output shaft to rotate and engage with the gear 154. This engages with the rack 143 on the sliding plate 142, causing the bridge frame 150 to move the two side frames 131. This, in turn, causes the square frame 120 (fixed to the side frames 131) and the square frame 111 (fixed to the side frames 131) to move the plastic fabric downwards. When the square frame 120 engages with the hollow base 210, the softened plastic fabric is tightly pressed against the top of the hollow base 210. At this point, by connecting the air pump to the exhaust port 211, the plastic fabric... When the air pump is activated, the gas inside the hollow base 210 is extracted. At this time, the pressure inside the hollow base 210 decreases, and the air between the plastic cloth and the top of the hollow base 210 can be extracted through the air suction hole 221. At this time, the pressure between the hollow base 210 and the softened plastic cloth decreases. Under the action of external air pressure, the softened plastic cloth will tightly adhere to the surface of the wheel mold 220. After the plastic cloth cools down, it can form a wheel cover that meets the requirements. After the production is completed, the servo motor 135 on the right side is driven to roll up the wheel cover and make the next wheel cover at the same time.

Any person skilled in the art can modify the present invention or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of the present invention fall within the scope of protection claimed by the present invention.
