Description

A positioning tool for precision sheet metal stamping

Technical Field

The utility model relates to the technical field of sheet metal stamping, and more specifically to a positioning tool for precision sheet metal stamping.

Background technique

Some metal sheets are plastically deformed by hand or die stamping to form the desired shape and size, and further formed into more complex parts by welding or a small amount of machining. This process is called sheet metal processing. Precision sheet metal parts are thin plate hardware parts, that is, parts that can be processed by stamping, bending, stretching, etc. Generally refers to parts whose thickness does not change during the processing. Corresponding are castings, forgings, machined parts, etc. For example, the iron shell outside the car is a precision sheet metal part, and some cabinets made of stainless steel are also precision sheet metal parts.

The existing patent CN218049994U, by rotating the No. 2 rotating block, the threaded rod drives the clamp to press the workpiece, which is conducive to quickly pressing square and round workpieces and improving the processing efficiency of the workpiece; rotating the No. 1 rotating block to rotate the bidirectional screw, and then the two positioning columns move on the outside of the bidirectional screw, which is conducive to adjusting the spacing between the two positioning columns according to the diameter of the round workpiece, so as to facilitate the processing of round workpieces of different diameters, but for the stamping of precision sheet metal, when the stamping mechanism is stamping, slight friction is easily generated between the clamp and the workpiece in the vertical direction, affecting the processing accuracy. In view of this, we propose a positioning tool for precision sheet metal stamping.

Detailed ways

The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

Example:

Please refer to Figures 1-4, a positioning tool for precision sheet metal stamping includes a base 1, and a fixing mechanism 2 is movably connected to the base 1; it is used to fix the sheet metal part to be stamped on the top surface of the base 1.

The fixing mechanism 2 includes a connecting block 201, a movable frame 202 is arranged inside the connecting block 201, a limiting column 203 is arranged at one end of the outer side of the movable frame 202, a clamping block 204 is sleeved on the limiting column 203, and rubber pads 205 are arranged at both ends of the clamping block 204. By arranging the rubber pads 205 at both ends of the clamping block 204 in the vertical direction, when the stamping mechanism stamps the sheet metal part, the sheet metal part will be subjected to downward pressure, and at this time, the clamping block 204 will move slightly downward with the sheet metal part, so that the rubber pad 205 is squeezed, thereby slowing down the moving friction between the sheet metal part and the clamping block 204, avoiding damage to the side of the sheet metal part, and at the same time will not affect the fixed position of the sheet metal part. And because the elastic deformation of the rubber pad 205 is small, the sheet metal part will not shift when it is not subjected to the pressure of stamping.

In the present application, the limiting column 203 is a prismatic structure, which limits the clamping block 204 so that the clamping block 204 can only move in the vertical direction. The rubber pad 205 is sleeved on the limiting column 203, and the clamping block 204 and the rubber pad 205 both slide in cooperation with the limiting column 203, so as to facilitate the movement of the clamping block 204 and the rubber pad 205 in the vertical position along the limiting column 203.

In the present application, a spring 206 is provided between the connecting block 201 and the movable frame 202, and a slide groove is provided inside the connecting block 201, and the movable frame 202 slides in cooperation with the slide groove. The setting of the spring 206 provides a certain buffer force when the clamping block 204 clamps the sheet metal, preventing the clamping block 204 from contacting the sheet metal too tightly and damaging the workpiece.

In the present application, movable plates 3 are arranged on both sides above the base 1, and the movable plates 3 can move along the base 1. The fixing mechanism 2 is arranged on the inner side of the movable plate 3. Limiting grooves 101 are arranged on both sides of the base 1. Both ends of the movable plate 3 extend into the limiting grooves 101. Both ends of the movable plate 3 are slidably matched with the limiting grooves 101. The limiting grooves 101 limit the positions of the two ends of the movable plate 3, so that the movable plate 3 can move in a straight line along the direction of the limiting grooves 101.

In the present application, a mounting groove 301 is provided on the inner side of the movable plate 3 , and a connecting rod 4 is rotatably connected in the mounting groove 301 . The connecting rod 4 is provided with two threaded sections with opposite rotation directions.

The connection blocks 201 on the same side are arranged in two groups, and the connecting rod 4 passes through the two groups of connection blocks 201 in sequence, and the connection blocks 201 are threadedly connected with the threaded sections. The distance between the two groups of connection blocks 201 can be adjusted by rotating the connecting rod 4, so that it is convenient to adjust according to sheet metal workpieces of different sizes.

In the present application, a hand wheel 5 is provided on one side of the movable plate 3 , and the hand wheel 5 passes through the movable plate 3 and is connected to one end of the connecting rod 4 , so that the connecting rod 4 is rotated by the hand wheel 5 .

In the present application, a baffle 102 is provided at the position of the base 1 outside the movable plate 3, and a cylinder 6 is provided outside the baffle 102, and the output shaft of the cylinder 6 is connected to the movable plate 3. The output shaft of the cylinder 6 is used to push the movable plate 3 to move, thereby fixing the positions of both sides of the sheet metal.

Working principle: When using the utility model, install the stamping die in the groove on the top surface of the base 1, and then place the precision sheet metal to be processed on the top surface of the die. First, adjust the distance between the two connecting blocks 201 on the same side according to the size of the sheet metal, and then use the output shafts of the cylinders 6 on both sides to push the movable plate 3 to move inward, so that the fixing mechanism 2 fixes the positions of both sides of the sheet metal. By setting a spring 206 between the connecting block 201 and the movable frame 202, when the clamping block 204 is clamped with the sheet metal, the spring 206 is in a compressed state. The setting of the spring 206 makes the clamping block 204 have a certain buffering force when the sheet metal is clamped, so as to prevent the clamping block 204 from contacting the sheet metal too tightly and clamping the workpiece.

When adjusting the distance between the two connection blocks 201 , the hand wheel 5 is rotated to drive the connecting rod 4 to rotate. When the connecting rod 4 rotates, the connection blocks 201 located on the two threaded sections of the connecting rod 4 will move relatively, thereby changing the distance between the two connection blocks 201 .
