Description

Technical Field

[0001] The present invention relates to the technical field of medical facility manufacturing, and particularly relates to a pipe bending device for blood collection chair production. Background Art

[0002] A blood collection chair is a special device used for blood donation or blood collection in medical places. The bracket of the blood collection chair is a metal bracket formed by bending, welding, and bolt connection of metal pipes. The bending process of the metal pipes is generally completed using a bending device to form a U-shaped leg frame of the blood collection chair.

[0003] However, for the current pipe bending device of the blood collection chair frame, when bending the pipe body, it is necessary to manually operate the hydraulic press for support and bending. When manually loading, it is necessary to accurately measure the positional relationship between the pipe body and the hydraulic equipment. During the unloading process, manual unloading is required, resulting in low safety, inconvenient operation, and difficulty in achieving efficient production. Summary of the Invention

[0004] In view of this, the present invention provides a pipe bending device for blood collection chair production, which has an automatic alignment structure and can align the pipe body through its own structure for auxiliary bending, thereby improving the bending accuracy and efficiency. Additionally, it has an automatic unloading function, and the finished product automatically drops after bending, making the processing more convenient.

[0005] The present invention provides a pipe bending device for blood collection chair production, specifically including: a hydraulic compressor, a rear connecting plate is fixedly connected to the rear of the hydraulic compressor, and an upper fixing table is fixedly connected above the rear connecting plate. The upper fixing table includes: a lower wheel frame, which is fixedly connected to the lower surface of the upper fixing table; two lower connecting seats are provided, and both groups of lower connecting seats are fixedly connected to the lower surface of the upper fixing table; the lifting push plate is connected above the hydraulic compressor through the telescopic driving mechanism of the hydraulic compressor; two telescopic driving members are provided, and the two telescopic driving members are respectively fixedly connected to the upper surfaces of the two lower connecting seats through bolts; the front combined stop strip is fixedly connected to the push rod of the front telescopic driving member, and the front combined stop strip is slidably connected to the front guide block; the rear combined stop strip is fixedly connected to the push rod of the rear telescopic driving member, and the rear combined stop strip is slidably connected to the rear guide block. The rear combined stop strip includes: an inner push strip, which is fixedly connected to the rear of the rear combined stop strip through two round rods; five inner anti-detachment convex blocks are provided, and all five inner anti-detachment convex blocks are opened on the front surface of the rear combined stop strip; an inner positioning semi-groove is opened on the front side above the rear combined stop strip, and the inner positioning semi-groove is a groove with an arc structure.

[0006] Optionally, the hydraulic compressor includes: positioning and adjusting side plates. There are two positioning and adjusting side plates, which are respectively fixedly connected to both sides of the hydraulic compressor, and the upper half of the positioning and adjusting side plate is concave through bending processing.

[0007] Optionally, the lifting push plate includes: a lifting push table, which is fixedly connected to the upper surface of the lifting push plate; an inclined discharge plate, which is fixedly connected to the upper surface of the lifting push table by welding, and the inclined discharge plate is in an inclined state with the front end lower and the rear end higher.

[0008] Optionally, the lifting push table includes: lifting push wheels. There are two lifting push wheels, which are respectively rotatably connected to the lifting push table through bearings; a limit wheel groove, which is arranged on the wheel surface of the lifting push wheel, and the two sides of the groove body of the limit wheel groove are provided with ramp structures.

[0009] Optionally, the lower wheel frame includes: a right positioning wheel, which is rotatably connected to the right side of the middle gap of the lower wheel frame through a bearing, and a left positioning wheel, which is rotatably connected to the left side of the middle of the lower wheel frame through a bearing.

[0010] Optionally, the lower connecting seat includes: connecting rib plates, which are fixedly connected to the connecting plate of the lower connecting seat; guide blocks. There are two guide blocks, both of which are fixedly connected to the upper surface of the lower connecting seat, and a circular through groove is opened in the middle of the guide blocks.

[0011] Optionally, the front combined stop bar includes: an outer push bar, which is fixedly connected to the front side of the front combined stop bar through two connecting round rods; five anti - detachment round holes, all of which are round hole structures; an outer positioning semi - groove, which is opened at the upper rear side of the front combined stop bar, and the outer positioning semi - groove is a groove body with an arc structure.

[0012] Beneficial effects According to the blood collection chair support bending device of the embodiments of the present invention, compared with the traditional bending device, it has an automatic alignment structure, can align the pipe body through its own structure for auxiliary bending, thereby improving the bending accuracy and efficiency. In addition, it has an automatic unloading function, and the finished product automatically drops after bending, making the processing more convenient.

[0013] In addition, through the action of the positioning and adjusting side plates on both sides of the hydraulic compressor, the length between the hydraulic compressors is the length of the workpiece to be bent. When the workpiece is driven upward by the lifting push plate, the two ends of the workpiece contact the inner wall of the plate body of the positioning and adjusting side plate, and the workpiece is moved towards the middle through the action of the inclined surfaces of the two plate bodies, realizing the automatic centering of the workpiece. Compared with the traditional manual centering, the centering efficiency is faster and the accuracy is higher.

[0014] In addition, the position of the rear combined stop bar is controlled by the telescopic drive. When the lifting push table rises and the rod body is lifted to the position of the positioning wheel, the two telescopic drives are controlled to push the front combined stop bar and the rear combined stop bar towards the middle at the same time, so that the rear combined stop bar and the front combined stop bar are combined. The formed semi-circular groove plays a role in limiting and positioning the pipe body. The inner anti-disengagement convex block of the rear combined stop bar is inserted into the anti-disengagement round hole of the front combined stop bar to form a connection, thereby improving the connection tightness and firmness of the front combined stop bar and the rear combined stop bar, and avoiding the situation that the front combined stop bar and the rear combined stop bar are separated due to pressure.

[0015] In addition, with the rise of the lifting push table, during the rising process, the rod bodies located on the two lifting push wheels come into contact with the two positioning wheels. Through the extrusion of the lifting push wheels and the left positioning wheel and the right positioning wheel, the extrusion position of the workpiece to be bent is bent along the wheel body arcs of the right positioning wheel and the left positioning wheel, so as to realize the bending of the pipe body from both sides.

[0016] After the bending is completed, the two telescopic drives contract, so that the front combined stop bar and the rear combined stop bar return to their original positions respectively. The bent pipe body is in a U-shaped structure, and can then fall from between the two lifting push wheels and fall to the front of the bending device through the inclined discharge plate with an inclined structure, realizing the function of automatic discharging, which is convenient for workpiece collection. It can be seen that by setting the combined stop bar of this bending mechanism, the bent workpiece can fall automatically, greatly improving the material taking convenience of the product and being beneficial to improving the efficiency of bending processing.
