Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of optical glass strip roll round forming, and particularly relates to an automatic flat head device of a roll bar machine. BACKGROUND

[0002] With the development of the optical glass industry, the optical glass strip roll is pressed into a round bar and then sliced to become another main production method in addition to secondary compression processing. In normal cases, the two ends of the round bar will be hemispherical, and the two hemispherical parts are not suitable for subsequent production and processing based on the diameter, which increases the material cost. To deal with this situation, the production line uses manual auxiliary tools to perform flat head, that is, the two ends of the bar are modified by extrusion and flattening.

[0003] The following two points are insufficient when the manual auxiliary operation is used to perform flat head on the bar:

[0004] First, the operation experience and technology of the operator are required. The center axes of the lower compression roller and the two supporting rollers of the roll bar machine form an equilateral triangle, and when a small-diameter round bar is pressed, the space for the handheld flat head tool to work is small, and the operation is difficult. The clamping angle, force size and tool extraction direction of the handheld tool have a great influence on the flat head effect of the round bar;

[0005] Second, the work intensity is large. In order to improve the production efficiency, the production cycle of the automatic roll bar machine currently used has been shortened, and the time for the operator to perform auxiliary flat head operation in a unit cycle is short, which requires high concentration of attention, and continuous regular actions are easy to make people tired, increase the probability of operation errors, increase the material cost, shorten the service life of the operation equipment components, and even cause production accidents. In addition, monotonous work will affect the mental state of the operator during work, which is not conducive to the development of personnel mental health. SUMMARY

[0009] The transverse guide rod in the technical solution of the present application is two; the guide rod positioning holes are two, located on the side away from the working end of the flat head baffle, and symmetrically distributed above and below.

[0010] The flat head baffle between the guide rod positioning hole and the working end of the flat head baffle in the technical solution of the present application is provided with an arc groove matched with the supporting roller of the roller bar machine.

[0011] The pushing mechanism in the technical solution of the present application is composed of a pushing device connecting rod and a pushing device.

[0012] The pushing device connecting rod in the technical solution of the present application is fixedly connected with the flat head baffle and the pushing device at both ends, respectively.

[0013] The transverse guide rod in the technical solution of the present application is parallel to the pushing device connecting rod.

[0014] The pushing device in the technical solution of the present application is a pneumatic cylinder.

[0016] The technical solution of the present application further includes a pushing mechanism control circuit for controlling the pushing mechanism; and the pushing mechanism control circuit is connected with the roller bar machine control circuit.

DETAILED DESCRIPTION

[0027] The present invention will be further described below with reference to the accompanying drawings.

[0028] Example 1 Figures 1 to 5 As shown, the present invention is an automatic flattening device for a roller bar machine, comprising a set of two flattening baffles 1, two transverse guide rods 2, two propulsion mechanisms and a propulsion mechanism control circuit for controlling the propulsion mechanisms, wherein the propulsion mechanism control circuit is connected to the control circuit of the existing roller bar machine.

[0029] The two flat baffles 1 have identical structure and shape, each featuring a plate-like structure of defined thickness and hardness, constructed from high-temperature refractory material. The flat baffle 1 is an L-shaped baffle, consisting of an upper horizontal plate and a left vertical plate. The upper horizontal plate features an arcuate groove in the lower left portion for mate with one of the roll mill support rollers 6, an arcuate groove in the lower right portion for mate with the other roll mill support roller 6, and an arcuate groove in the upper right portion for mate with the roll mill lower pressure roller 5. The right end of the upper horizontal plate, located within the working space between the roll mill lower pressure roller 5 and the two roll mill support rollers 6, constitutes the flat baffle's working end 8. Guide rod locating holes 7 are symmetrically located at the upper and lower left sides of the left vertical plate. These holes allow the flat baffle 1 to be mounted on the transverse guide rod 2, ensuring stable lateral movement of the flat baffle.

[0030] The two transverse guide rods 2 each have a fixed diameter and fit into guide rod locating holes 7. They are fixed to the base of the roller mill and positioned parallel to and to one side of the roller mill's support rollers 6. The transverse guide rods 2 pass through guide rod locating holes 7 in the flat baffle 1, limiting the direction of movement of the flat baffle 1.

[0031] The propelling mechanism is composed of a propelling device connecting rod 3 and a propelling device 4. The propelling device 4 can be a conventional propelling device, such as a pneumatic cylinder. The propelling device connecting rod 3 is transversely connected to the flat head baffle 1 at one end by welding and is transversely connected to the extended end of the propelling device 4 at the other end by welding, and the propelling device connecting rod 3 is parallel to the transverse guide rod 2. Both of the propelling devices 4 are fixed on the base of the roller bar machine. The propelling device 4 provides power for the stable movement of the flat head baffle 1 along the transverse guide rod 2.

[0032] After the PLC control program is connected to the roller bar machine operation program, the actual action of the roller bar machine automatic flat head device is as follows Figure 5 The relationship between time and the height of the press roller is shown in the t-h broken line graph:

[0033] At T1, the pneumatic cylinder acts, and the flat head baffles 1 on both sides move to the middle, and the roller bar machine lower press roller 5 starts to descend from the highest point h0.

[0034] At T2, the flat head baffle 1 moves to the designated position, and the position of the blank is limited at the same time.

[0035] At T3, the roller bar machine lower press roller 5 contacts the blank, the roller bar machine lower press roller 5 is pressed down, and the roller round operation starts.

[0036] At T4, the roller bar machine lower press roller 5 continues to press down, and at this time, the shape of the blank is close to a round bar, but the diameter does not meet the process requirements. The blank ends are pressed flat by the flat head baffles 1 on both sides under the pressure of the flat head baffles 1. The pneumatic cylinder acts, and the flat head baffles 1 move to the ends for recovery.

[0037] At T5, the roller bar machine lower press roller 5 moves to the lowest point h2, the roller bar is formed, and the diameter meets the process requirements. The roller bar machine lower press roller 5 starts to rise.

[0038] At T6, the roller bar machine lower press roller 5 moves to the highest point h0, and the blank starts to fall.

[0039] At T7, the t1 action is repeated.

[0040] At T8, the t2 action is repeated. The working cycle period is entered.

[0041] In use, the roller bar machine lower press roller 5 in the automatic roller bar machine is moved towards the softening furnace, and the outer gap left between the roller bar machine support roller 6 is put into the working end 8 of the flat head baffle 1. The roller bar machine automatic flat head device is fixed at the outer designated position, and the corresponding PLC control program is connected to the roller bar machine automatic operation program.

[0042] Before formal rolling production, the corresponding key parameters that meet the production requirements of this batch are determined through debugging to realize the automatic flat head operation of the round bar rolling of the corresponding optical glass blank. While ensuring the quality of the flat head product, the artificial productivity is liberated. EMBODIMENT

[0043] On the basis of example 1, it is extended to flat head for double root bar rolling.

[0044] The two sides of the advancing mechanism are connected with two flat head baffles 1, and the flat head baffles 1 connected by the left and right sides of the advancing mechanism are staggered and work simultaneously, so that the double root bar rolling flat head can be realized. Embodiment

[0045] On the basis of example 2, it is extended to flat head for three root bar rolling.

[0046] The two sides of the advancing mechanism are connected with three flat head baffles 1, and the flat head baffles 1 connected by the left and right sides of the advancing mechanism are staggered and work simultaneously, so that the three root bar rolling flat head can be realized.
