Description

Technical Field

[0001] The invention relates to the technical field of stainless steel table knife production, in particular to a stainless steel table knife molding die. Background Art

[0002] In the production process of stainless steel table knives, an open press is required. The steel plate is placed on the lower die of the forming mold, and the upper die of the forming mold is hydraulically controlled to stamp toward the lower die of the forming mold to form the initial shape of the table knife. During the downward stamping process of the open press, the punch is pressed into the die, and the material is formed in the die, which causes greater wear on the die itself. When the material is stamped, the temperature of the material itself is high, and the die is easily damaged by heat and external forces. In common stamping dies, the die is often matched with the punch when in use. The die is used frequently and is more easily worn. Therefore, how to solve the above problems is the key to reducing production costs. Summary of the invention

[0018] 3. Because the distance between the left and right limit blocks is fixed, when the punch moves downward, the maximum downward movement distance of the punch will be limited, so that a specified gap is left between the punch and the buffer seat, avoiding the problem of excessive downward pressure of the punch, which causes serious damage to the replaceable die. In addition, because the limit block can slide up and down relative to the punch, it will not affect the buffer seat to buffer the downward pressure during stamping.

[0019] 4. The guide seat moves to drive the rotating roller to move, and then pushes the die mounting seat to move, so that the position of the replaceable die can be adjusted. Compared with the fixed guide seat, this method is more practical and can also correct the position of the die mounting seat without stopping the machine, thereby improving the processing efficiency.

By installing five replaceable dies 706 on the die mounting seat 704, the use frequency of a single replaceable die 706 can be reduced, and it can be After a replaceable die 706 is working, the replaceable die 706 is withdrawn from the working position, so that the temperature of the replaceable die 706 is reduced, and the workers are also used to clean and protect the replaceable die 706, which will not reduce the work efficiency, but also reduce the wear rate of the replaceable die 706, thereby achieving the purpose of reducing costs. The electric slide rail 701 drives the sliding seat 702 to move forward and backward, and then drives the elastic connecting seat 703 to move forward and backward. The elastic connecting seat 703 moves forward and backward and drives the die mounting seat 704 to move forward and backward, which is used to switch the position of the replaceable die 706. Because the die mounting seat 704 falls on the buffer seat 5, the bottom of the buffer seat 5 is the buffer spring 6, and the bottom of the die mounting seat 704 is the elastic connecting seat 703, so during the stamping process, the impact of the punch 4 pressing down can be buffered, further avoiding damage to the replaceable die 706, and a guide slide rail 708 is provided to guide the die mounting seat 704, so that the die mounting seat 704 will not deviate left and right during the forward and backward movement.

[0035] The elastic connecting seat 703 includes a guide rail seat 7031 and a connecting plate 7033. The guide rail seat 7031 is fixedly installed on the top of the sliding seat 702.

[0036] The guide rail 708 includes a guide seat 7081, which is arranged on the left and right sides of the die mounting seat 704. The inner side of the guide seat 7081 is rotatably connected with a rotating roller 7082 through a bearing. The rotating roller 7082 contacts the outer wall of the die mounting seat 704. The outer wall of the guide seat 7081 is connected with a support column 7083, and the support column 7083 is fixedly installed on the electric rail 701. The height of the rotating roller 7082 is greater than the thickness of the die mounting seat 704. The guide seat 7081 is provided for installing the rotating roller 7082. The left and right groups of rotating rollers 7082 are pressed against the die mounting seat 704 to guide the die mounting seat 704, so that the die mounting seat 704 will not deviate left and right during the forward and backward movement. Moreover, because the height of the rotating roller 7082 is greater than the thickness of the die mounting seat 704, the rotating roller 7082 can press against the die mounting seat 704 during the upward and downward movement of the die mounting seat 704.

[0037] A vertical plate 16 is fixedly installed on the top of the electric slide rail 701, and a positioning sensor 17 is fixedly installed on the outer wall of the vertical plate 16. The detection end of the positioning sensor 17 faces the die mounting seat 704.

An industrial camera 20 is fixedly installed on the mounting plate 19. The industrial camera 20 is located directly above the die mounting seat 704. The second vertical plate 18 is symmetrically staggered with the first vertical plate 16. The replaceable die 706 is photographed by the industrial camera 20 to determine whether there are impurities inside the replaceable die 706 or whether the replaceable die 706 is damaged. Because the first vertical plate 16 is staggered with the second vertical plate 18, the staggered position can allow employees to stand or install other automated equipment;

[0039] A reserved mounting seat 21 is fixedly installed on the top of the electric slide rail 701. There are two groups of reserved mounting seats 21, which are respectively located near the vertical plate 16 and the vertical plate 2 18. The reserved mounting seats 21 are used to install other automation equipment.

A guide hole is opened on the baffle plate 9, and an anti-tilt roller 11 is slidably arranged in the guide hole. A connecting plate 2 10 is fixedly installed on the outer wall of the anti-tilt roller 11. The left and right anti-tilt rollers 11 are respectively against the left and right outer walls of the buffer seat 5. The anti-tilt rollers 11 are provided to limit the buffer seat 5 to avoid the problem of left and right deviation of the buffer seat 5.

[0041] An anti-slip rod 13 is fixedly installed on the inner wall of the upper die seat 2, and a limit block 12 is provided on the outer wall sliding sleeve of the anti-slip rod 13.

The left and right outer walls of the punch 4 are provided with integrally formed protrusions 15, and the protrusions 15 are slidably arranged in the limit grooves 14. The limit block 12 falls on the buffer seat 5. Because the spacing between the left and right limit blocks 12 is fixed, when the punch 4 moves downward, the maximum downward movement distance of the punch 4 will be limited, so that a specified gap is left between the punch 4 and the buffer seat 5, avoiding the problem of excessive downward pressure of the punch 4, resulting in serious damage to the replaceable die 706, and because the limit block 12 can slide up and down relative to the punch 4, it will not affect the buffer seat 5 to buffer the downward force during stamping;

[0042] There are two electric slide rails 701, which are respectively located at the front and rear of the mold base 1. There are two sliding seats 702 on an elastic connecting seat 703, which increase the support force of the die mounting seat 704 at both ends and avoid the problem of serious deformation of the middle part of the die mounting seat 704 due to force.

[0043] Working principle: When in use, the replaceable die 706 is installed in the five die mounting grooves 705 in turn, and then the sliding seat 702 is driven to move back and forth by the electric slide rail 701, thereby driving the elastic connecting seat 703 to move, and the movement of the elastic connecting seat 703 drives the die mounting seat 704 to move, and then one of the replaceable dies 706 is extended to the bottom of the punch 4, and then the stamping and forming is started. After stamping, the replaceable die 706 is withdrawn from the working position to facilitate workers or robots to take out the molded parts, and then the replaceable die 706 is cleaned or oiled. During this period, the replaceable die 706 can also cool down, which reduces the frequency of use of a single replaceable die 706 and also reduces the cleaning and maintenance costs of the replaceable die 706.

When the positioning sensor 17 detects that the replaceable die 706 is offset, the guide seat 7081 is moved to drive the rotating roller 7082 to move, thereby pushing the die mounting seat 704 to move and adjust the position of the replaceable die 706. Compared with the fixed guide seat 7081, this method is more practical and can also correct the position of the die mounting seat 704 without stopping the machine, thereby improving the processing efficiency.

[0057] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present invention.
