Description

Technical Field

[0001] The utility model belongs to the field of thermoplastic pneumatic joint processing, in particular to a flash processing device for thermoplastic forming of pneumatic joints. Background Art

[0002] In the process of making pneumatic joints through thermoplastic molding, some thermoplastics will overflow into the gaps such as the mold parting line and the demolding line and remain on the pneumatic joint to form residual material edges called flash. The flash will affect the appearance and even the assembly of the product. Therefore, it is necessary to use flash processing equipment to cut off the flash on the molded pneumatic joint.

[0003] At present, the existing flash processing equipment does not have a protective function. In the process of cutting the flash, plastic fragments are easy to burst out, posing a threat to the surrounding workers. At the same time, the burst plastic fragments will also increase the difficulty of cleaning and collection.

[0004] Therefore, in view of the problem that the existing flash processing equipment does not have a protective function and the plastic fragments that burst out during the flash cutting process pose a threat to the surrounding workers, the existing flash processing equipment is improved so that it can prevent the fragments from bursting out and ensure the safety of the surrounding workers. Utility Model Content

[0005] In order to overcome the problem that the existing flash processing equipment does not have a protective function, the plastic fragments that break out during the cutting process can easily scratch the staff.

[0006] The technical solution of the utility model is: a flash processing device for thermoplastic forming of pneumatic joints, comprising a supporting base, a protective cover, a clamping assembly, a flash processing mechanism, a moving assembly, and a chip removal mechanism; a transparent polycarbonate protective cover is installed on the supporting base, a movable door for loading and unloading materials is connected to the protective cover by a hinge, a protective cover for fixing the pneumatic joint is installed on the supporting base, a flash processing mechanism is arranged in the protective cover, a moving assembly for adjusting the distance between the flash processing mechanism and the clamping assembly is installed on the supporting base, and a chip removal mechanism is installed on the supporting base.

[0007] Preferably, a transparent protective cover is added to the existing flash processing equipment to prevent plastic fragments cut by the flash processing mechanism from breaking, flying out and scratching the staff. The distance between the flash processing mechanism and the clamping component of the fixed pneumatic joint is adjusted by moving the component, so that the flash processing device can adapt to pneumatic joints of various sizes. At the same time, the chip removal mechanism cleans and collects these tiny plastic fragments, ensuring the cleanliness of the equipment while facilitating the subsequent secondary processing of the plastic fragments.

[0008] Preferably, the clamping assembly includes a centering chuck and claws; a centering chuck is arranged on the right side of the supporting base, and three claws with arc-shaped clamping surfaces are movably connected to the centering chuck, a rotating shaft is fixedly connected to the left side of the centering chuck, and a transmission element is installed on the right side of the protective cover and is connected to a motor on the rotating shaft. The claws will move synchronously on the centering chuck, and the arc-shaped clamping surface fits with the pneumatic joint. After the motor is started, it drives the rotating shaft and the pneumatic joint fixed on the chuck.

[0009] Preferably, the burr processing mechanism includes a hot cutter and a grinding block; a hot cutter is arranged in the protective cover and is opposite to the clamping assembly, and a grinding block is arranged in front of the hot cutter. By rotating the pneumatic joint, the hot cutter cuts the burr of the pneumatic joint, and the grinding block is used to grind the incision produced by the cutting to prevent the incision from scratching the staff.

[0010] Preferably, the moving component includes a slide groove, a slider, and a cylinder; a slide groove is opened on the support base, and the slider is slidably connected in the slide groove. A cylinder with a piston rod connected to the right side of the slider is installed on the right side of the support base. After the cylinder is started, the piston rod pushes the slider and the flash processing mechanism installed above the slider to move in the slide groove, thereby changing the distance between the flash processing mechanism and the clamping assembly.

[0011] Preferably, the moving component further includes a lifting platform, a threaded rod, and a limit column; a lifting platform is arranged on the slider, a threaded rod is inserted on the slider, a limit column is fixedly connected to the slider, the lifting platform is sleeved on the threaded rod and the outside of the limit column, a transmission element is arranged in the slider and is connected to the motor on the threaded rod, after the motor is started, the threaded rod starts to rotate, and under the restriction of the limit column, the lifting platform and the burr processing mechanism installed on the lifting platform cannot rotate with the threaded rod, but move up and down on the threaded rod, so as to change the height of the burr processing mechanism.

[0012] As a limitation, the moving component also includes a moving block and an electric push rod; a moving block with a hot cutting knife and a grinding block installed on the top is arranged on the lifting platform, and an electric push rod with a piston rod connected to the front side of the moving block is installed on the front side of the lifting platform. The piston rod of the electric push rod pushes the moving block and the hot cutting knife or grinding block installed on the moving block to move, which can prevent the grinding block and the hot cutting knife from forming obstacles when each other is working.

[0013] Preferably, the chip removal mechanism includes a chip box and a dust collector head; a chip box with a built-in fan is installed on the outside of the support base, and a dust collector head connected to the chip box through an air duct is plugged into the inside of the protective cover. After the fan in the chip box is started, the dust collector head sucks the plastic debris generated by cutting and grinding into the chip box through the air duct, cleans and collects these plastic fragments, and facilitates subsequent secondary processing of the plastic fragments.

[0014] Beneficial effects of the utility model:

[0015] 1. A protective cover is installed on the flash processing device to prevent the plastic fragments generated by cutting the flash from splashing out. The protective cover is made of transparent polycarbonate material, which is the same material used in riot shields and has high strength. The fragments are blocked in the protective cover to protect the safety of surrounding staff. At the same time, the transparency also makes it convenient for staff to observe the flash processing of internal pneumatic joints;

[0016] 2. The hot cutter cuts off the flash on the outside of the pneumatic joint. After the cutting is completed, the grinding block grinds the incision. The plastic debris generated by cutting and grinding is sucked into the chip collection box through the vacuum head, which has the effect of cleaning the device platform. At the same time, these thermoplastic plastic fragments can be collected for secondary processing to prevent waste. BRIEF DESCRIPTION OF THE DRAWINGS
