Description

Flat steel blanking fixture

technical field

The utility model relates to a blanking fixture, in particular to a flat steel blanking fixture.

Background technique

Since the self-contained clamps of the band sawing machine cannot meet the process requirements, the positioning size must be checked manually with a standard block every time the sawing machine is cut. The error of the sawing size is artificially large, resulting in different sizes of the cutting material and skewed workpiece incision. The parallelism and verticality are not good enough to meet the process standards, which not only causes waste of materials, but also has a great impact on the processing quality of subsequent processes. Although the fixture has been improved several times, the effect is minimal, and the product processing quality is still not ideal.

Utility model content

The purpose of the utility model is to solve the existing deficiencies and provide a flat steel blanking fixture.

In order to solve the above technical problems, the utility model adopts the following technical solutions:

A flat steel blanking fixture, comprising a flat bottom plate, the front end of the flat bottom plate is provided with a movable jaw, the rear end of the flat bottom plate is provided with a fixed jaw, and the upper right side of the flat bottom plate is provided with a concave groove. The left side plate surface of the concave groove is a horizontal plane, and a positioning block is slidingly connected to the left and right in the concave groove, and the upper end surface of the positioning block is higher than the left side plate surface of the concave groove, and the positioning block is provided with two "U"-shaped slot, the "U"-shaped slot is provided with a positioning screw, and the right side of the flat bottom plate is provided with an adjustment screw, and the adjustment screw passes through the flat bottom plate and is connected to the positioning block. The positioning block, The design of the positioning screw and the adjusting screw makes it necessary to move the positioning block to the required size through the adjusting screw and fix it with the positioning screw when setting the size. Each batch of blanks only needs to be set once to achieve continuous sawing. When feeding The material is sent to the positioning block to be close, the size is accurately positioned, and the sawing machine can be clamped to work.

Further, the upper end surface of the positioning block is 10mm higher than the end surface of the notch of the concave groove, which facilitates the positioning of the blank.

Further, the flat bottom plate is an extended flat bottom plate, and the length of the fixture base is doubled to that of the ordinary flat bottom plate, which is equal to the length of the double-size material, and the contact area between the material surface and the high surface of the bottom surface of the fixture is increased to make it fully contact and improve The clamping effect reduces the slight vibration or displacement that may occur during sawing, thereby preventing the loss of precision during sawing.

Furthermore, four circular through holes are provided on the flat bottom plate, which has a simple structure and a reasonable design.

Compared with the prior art, the flat steel blanking fixture of the utility model adopts the design of positioning block, positioning screw and adjusting screw, so that when the size is fixed, only the positioning block needs to be moved to the required size and fixed with screws, and each batch of blanks It only needs to set the size once to realize continuous sawing. When feeding, the material is sent to the positioning block to be close, the size is accurately positioned, and the sawing machine can be clamped to work. Increase the length of the base of the fixture to double the length of the ordinary flat bottom plate, equal to the length of the double-size material, increase the contact area between the material surface and the high surface of the bottom surface of the fixture, make them fully contact, improve the clamping effect, and reduce the possibility of sawing. Slight vibration or displacement, so as to prevent the decrease of precision when sawing.

Description of drawings

Fig. 1 is the structural representation of the utility model.

1. Flat bottom plate, 2. Movable jaw, 3. Fixed jaw, 4. Concave groove, 5. Positioning block, 6. "U" shaped groove, 7. Positioning screw, 8. Adjusting screw, 9. Round through hole.

Detailed ways

In order to further understand the utility model, the utility model is described below in conjunction with the accompanying drawings.

As shown in Figure 1, a flat steel blanking fixture provided in this embodiment includes a flat bottom plate 1, a movable jaw 2 is provided at the front end of the flat bottom plate 1, and a fixed jaw 3 is provided at the rear end of the flat bottom plate 1 , the upper right side of the flat bottom plate 1 is provided with a concave groove 4, the left side plate surface of the concave groove 4 is a horizontal plane, and a positioning block 5 is slidingly connected to the left and right in the concave groove 4, and the positioning block 5. The upper end surface is higher than the left side of the concave groove 4. The positioning block 5 is provided with two "U"-shaped grooves 6, and the "U"-shaped groove 6 is provided with a positioning screw 7. The flat bottom plate The right side of 1 is provided with an adjustment screw 8, and the adjustment screw 8 passes through the flat bottom plate 1 and is connected with the positioning block 5 in transmission.

Explain the various parts of this embodiment:

1) The upper end surface of the positioning block 5 is 10mm higher than the end surface of the notch of the concave groove 4.

2) The flat bottom plate 1 is an extended flat bottom plate.

3) Four circular through holes 9 are provided on the flat bottom plate 1 .

Working principle: When the fixture starts to work, first determine the position of the positioning block by adjusting the screw according to the size of the blank, then fix it with the positioning screw, open the movable jaw, and send the blank into the bottom surface of the fixture so that one side is close to the fixed jaw and the other side is close to the fixed jaw. The positioning block is close, and finally the movable jaw is clamped with the third side of the blank through the hydraulic device to complete the entire blank clamping process and enter the follow-up processing.

The above are only preferred embodiments of the present utility model, and it should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present utility model, various deformations and improvements can also be made, which should also be regarded as Protection scope of the present utility model.
