Description

Technical Field

[0001] The utility model belongs to the technical field of terminal processing, in particular to a terminal bending machine. Background Art

[0002] Terminal blocks are an accessory product used to achieve electrical connections. They are classified as connectors in the industry. With the increasing degree of industrial automation and the increasingly stringent and precise requirements for industrial control, the use of terminal blocks has gradually increased. With the development of the electronics industry, the scope of use of terminal blocks has expanded, and there are more and more types of terminal blocks.

[0003] Some existing terminal bending mechanisms usually include a fixed tool for fixing the terminal, a punch for determining the bending curvature of the terminal, and a bending die set (including a concave die matching the punch) that allows the terminal to be bent on the punch along the curvature determined by the punch. The terminal can be bent on the punch by controlling the movement of the bending die set. In order to reduce the error, the punch is usually set close to the position where the terminal extends out of the fixed tool (such as Figure 1 As shown), in actual use, the inventors found that when the operator puts the terminal into the fixed tooling, it is blocked by the punch, which will prolong the single insertion time. The shorter the terminal is, the closer its end will be to the punch, and the greater the impact will be. In addition, the operator's hands are also easily injured by scraping, cutting, and pressing by the punch and its fixed parts. Utility Model Content

[0004] The purpose of the utility model is to provide a terminal bending machine to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, a technical solution adopted by the utility model is: a terminal bending machine, including an operating table, on which a terminal fixing tool, an angle adjustment punch group and a bending assembly are arranged, and the operating table is also provided with a first driving mechanism for controlling the angle adjustment punch group to reach and move away from the terminal bending position.

[0006] Preferably, the horizontal height of the angle adjusting convex group after the first driving mechanism drives the angle adjusting convex group away from the terminal bending position is lower than the horizontal height of the angle adjusting convex group when the first driving mechanism drives the angle adjusting convex group to the terminal bending position.

[0007] Preferably, the fixing fixture comprises a fixing base and a fixing module arranged thereon, the fixing module comprises a fixing block with a fixing groove, and the fixing block is provided with a locking module for preventing the terminal from escaping from the fixing groove.

[0008] Preferably, the locking module comprises a fixed column and a shifting block sleeved on the fixed member, and an elastic member is sleeved on the fixed column. The shifting block is fitted on the surface of the fixed block under the action of the elastic member.

[0009] Preferably, the angle adjustment convex mold assembly comprises a mounting block with a mounting groove, and a convex module is arranged in the mounting groove.

[0010] Preferably, the male mold and the mounting groove are detachably connected, and the mounting block is provided with a fastener for tightly fitting the male mold block and the mounting groove.

[0011] Preferably, the bending assembly comprises a fixing frame and a second driving mechanism arranged thereon, and a concave die is arranged on the output end of the second driving mechanism.

[0012] Preferably, the die is a fixed pulley disposed on the output end of the second driving mechanism, and when the bending assembly is working, the terminal falls into the groove of the fixed pulley;

[0013] After the terminal is bent, a first straight arm is formed in the fixed groove, a curved arm at the bent portion and a second straight arm connected to the curved arm. The second driving mechanism controls the movement direction of the fixed pulley to be consistent with the direction of the second straight arm. An auxiliary molding surface that fits the second straight arm is present on the convex module.

[0014] Preferably, there is a fixing portion on the terminal, and there is a matching groove on the fixing groove for matching with the fixing portion.

[0015] Beneficial effects of the utility model: the scheme drives the angle-adjusting convex die set to reach and move away from the terminal bending position by setting a first driving mechanism. During the manual feeding process, the angle-adjusting convex die set is moved away from the terminal fixing tool, so that the space for feeding the terminal fixing tool is open. Therefore, it is convenient for feeding, and no collision occurs between human body parts and equipment, which effectively reduces related hidden dangers.

[0016] Due to the limitation of human operating posture, the movement of the angle adjustment punch group at the same or similar horizontal height may still cause obstruction to the forearm of the person. By setting the difference that "the horizontal height of the angle adjustment punch group after the first driving mechanism drives the angle adjustment punch group away from the terminal bending position is lower than the horizontal height of the angle adjustment punch group when the first driving mechanism drives the angle adjustment punch group to reach the terminal bending position", the probability of collision can be reduced.

The operating table 1 is also provided with a first driving mechanism 7 for controlling the angle adjustment punch group to reach and move away from the bending position of the terminal 3. In this embodiment, the first driving mechanism 7 can be a cylinder.

[0026] See also Figure 5The fixing tool 2 includes a fixing base 21 and a fixing module arranged thereon, and the fixing module and the fixing base 21 are detachably connected to facilitate the replacement of fixing modules of different specifications, etc. The fixing module includes a fixing block 22 with a fixing groove, wherein a fixing portion 31 is present on the terminal 3, and a matching groove used to cooperate with the fixing portion 31 is present on the fixing groove. At the same time, a locking module for preventing the terminal 3 from escaping from the fixing groove is provided on the fixing block 22, and the locking module includes a fixing column 23 and a shifting block 24 sleeved on the fixing member. An elastic member 25 is also sleeved on the fixing column 23, and the elastic member 25 can be a spring. Under the action of the elastic member 25, the shifting block 24 is made to fit on the surface of the fixing block 22. By providing the elastic member 25, both the fixing effect can be ensured and the hard collision between the shifting block 24 and the fixing block 22 can be avoided.

[0027] See also Figure 4 , a connecting plate 71 which moves therewith is fixed at the output end of the first driving mechanism 7, and the angle adjustment convex mold group includes a mounting block 6 with a mounting groove 61, and the mounting block 6 can be fixed on the connecting plate 71 by bolts or the like and move therewith, and a convex module 4 is arranged in the mounting groove 61, and the convex module 4 and the mounting groove 61 are detachably connected, and a fastener is arranged on the mounting block 6 to fasten the convex module 4 and the mounting groove 61. In this embodiment, there is a fixing hole 62 which penetrates from the side to the mounting groove 61, and the fixing hole 62 is a threaded hole, and a fastening bolt is connected to the inner thread thereof, and the fastening bolt is also a fastener. When the convex module 4 is inserted into the mounting groove 61, the convex module 4 is tightly attached to the inner side wall of the mounting groove 61 by tightening the fastening bolt, so that the convex module 4 and the mounting groove 61 are fixed, wherein, refer to Figure 3 , Figure 5 A directional mounting block 626 is fixed on the fixed base 21, and one side of the directional mounting block 626 is inclined. The first driving mechanism 7 is fixed on the inclined surface of the directional mounting block 626 and its output end moves along the direction of the inclined surface, thereby achieving that the horizontal height of the angle adjusting convex group after the first driving mechanism 7 drives the angle adjusting convex group away from the bending position of the terminal 3 is lower than the horizontal height of the angle adjusting convex group when the first driving mechanism 7 drives the angle adjusting convex group to reach the bending position of the terminal 3.

[0028] See also Figure 3 The bending assembly 5 includes a fixing frame 51 and a second driving mechanism 52 arranged thereon. The second driving mechanism 52 may be a cylinder. A die 53 is arranged on the output end of the second driving mechanism 52. The die 53 is a fixed pulley arranged on the output end of the second driving mechanism 52. When the bending assembly 5 is working, the terminal 3 falls into the groove of the fixed pulley.

[0029] After being bent, the terminal 3 forms a first straight arm located in the fixed groove, a curved arm at the bent portion and a second straight arm connected to the curved arm. The second driving mechanism 52 controls the movement direction of the fixed pulley to be consistent with the direction of the second straight arm. The convex module 4 has an auxiliary molding surface that fits with the second straight arm.

[0030] Working principle and process:

[0031] When the bending machine in the present scheme is in the initial state, the output ends of the first driving mechanism 7 and the second driving mechanism 52 are both in the retracted state. At this time, the material is manually loaded, and the terminal 3 is initially fixed by the cooperation between the fixing portion 31 and the matching groove. Then, the oscillating dial block 24 partially closes the opening of the fixing groove. Affected by the cross-sectional shape of the terminal 3, if the cross-section of the terminal 3 is circular and not suitable for fixing, the dial block 24 needs to be moved to the top of the fixing portion 31 of the terminal 3, so as to fix the terminal 3 in the fixing groove. Then, the equipment is started, and the first driving mechanism 7 controls the convex module 4 to reach the bending position of the terminal 3. Then, the second driving mechanism 52 controls the movement of the concave die 53, so as to complete the bending of the terminal 3 on the convex module 4. Then, the first driving mechanism 7 and the second driving mechanism 52 are reset respectively, and the dial block 24 is opened to take out the processed terminal 3. Figure 1 The original bending machine described above, in this solution, a first driving mechanism is set to drive the angle-adjusting punch group to reach and move away from the terminal bending position. During manual loading, the angle-adjusting punch group is moved away from the terminal fixing tooling, so that the space for loading the terminal fixing tooling is open. Therefore, loading is convenient, and collision between human body parts and equipment will not occur, effectively reducing related hidden dangers.
