[0002] After extrusion, aging, and sandblasting, aluminum alloy photovoltaic frame profiles require various deep processing steps, including stamping. The stamping die is a consumable part, and its cost is relatively high. Therefore, an improved design that can extend service life and save costs is still needed. Utility Model Content

[0003] To address the aforementioned problems, the purpose of this utility model is to provide a double-headed punch and a punch assembly with a corresponding power block.

[0004] According to one aspect of the present invention, a double-headed punch is provided, which is configured to have a longitudinal section with a parallelogram outer contour and a polygonal cross section. The inclined sides at both ends in the longitudinal direction are respectively configured as inclined blade surface I and inclined blade surface II. Grooves I and groove II for fitting and fixing are respectively provided on the surfaces of the two transverse sides adjacent to the corresponding inclined blade surface I and inclined blade surface II.

[0005] Preferably, the double-headed punch is configured with a rectangular cross-section and a centrally symmetrical longitudinal section.

[0006] Preferably, in the longitudinal direction, groove I and groove II are separated from the corresponding inclined blade surface I and inclined blade surface II by a set distance and do not overlap.

[0007] Preferably, the oblique cutter face I and oblique cutter face II are formed at a 45° angle with the adjacent side face I and side face II, respectively, to form cutter head I and cutter head II.

[0008] According to another aspect of the present invention, a punch assembly is provided, including the aforementioned double-headed punch and a power block. The power block has a fitting groove that opens to one side. The bottom surface of the fitting groove includes an inner inclined surface I near the opening side and an inner inclined surface II away from the opening side. In a longitudinal section view, the inner inclined surface I and the inner inclined surface II are broken lines formed by two line segments that form a predetermined angle with each other. When the double-headed punch is inserted into the fitting groove along the groove wall adjacent to the inner inclined surface I, the inclined blade surface I or the inclined blade surface II is in contact with the inner inclined surface I. At the same time, the corresponding blade tip extends beyond the inner inclined surface I and extends into and is suspended at the bottom of the groove with the inner inclined surface II as the groove bottom surface. A gap is formed between the punch and the inner inclined surface II and between the punch and the groove wall on the other side opposite to the inner inclined surface I.

[0009] Preferably, the punch assembly further includes a right guide roller and a left guide roller disposed on both sides of the double-headed punch for respectively abutting against the two opposite sides of the double-headed punch.

[0010] Preferably, the power block also has a threaded hole communicating with the fitting groove, and the double-headed punch is fixed in the fitting groove by inserting a bolt into groove I or groove II.

[0011] Preferably, the left side of the tank wall adjacent to the inner inclined surface I forms a 135° angle with the inner inclined surface I, and the right side of the tank wall opposite to the inner inclined surface I forms a 30° angle with the inner inclined surface II.

[0012] The beneficial effects of this invention are: both ends are punches, so if one punch wears out, the other end can be replaced and the device can continue to be used, doubling the service life and saving costs. The special structure of the power block can be perfectly adapted to double-ended punches with punches at both ends. Attached Figure Description

[0022] Bolt 500 includes: threaded rod 501 and nut 502.

[0023] <Double-headed punch 100>

[0024] From the front view, the whole structure has a centrally symmetrical structure.

[0025] The cutter head I101 is located on the left and right sides of the front view, and is composed of the side surface I105 and the oblique cutter surface I109 respectively, with the two surfaces at a 45° angle.

[0026] The cutter head II102 is located on the left and right sides of the main view, and is composed of the side surface II106 and the oblique cutter surface II110 respectively, with the two surfaces at a 45° angle.

[0027] The beveled face I109 and the beveled face II110 are parallel to each other.

[0028] Groove I103 is located on side I105, and groove II104 is located on side II106.

[0029] Side I 105 and side II 106 are parallel to each other, and side III 107 and side IV 108 are parallel to each other.

[0030] Side I 105 and side III 107 are perpendicular to each other.

[0031] Side II 106 and side IV 108 are perpendicular to each other.

[0032] <Power Block 200>

[0033] The threaded hole 202 is perpendicular to the right side face 208.

[0034] The settling tank I203 consists of a left side surface 205, an inner inclined surface I206, and a right side surface 208.

[0035] The settling tank II204 consists of an inner inclined surface II207 and a right side surface II208.

[0036] The left side 205 and the right side 208 are parallel to each other.

[0037] The left side 205 forms a 135° angle with the inner inclined surface I206.

[0038] The inner inclined plane II207 forms a 30° angle with the right side plane 208.

[0039] Left 209 and right 211 are parallel to each other.

[0040] The bottom surface 210 and the left surface 209 are perpendicular to each other.

[0041] The left side 205 is perpendicular to the bottom side 210.

[0042] <Assembly and Assembly>

[0043] With the double-headed punch 100 punch cutter II (see Figure 1 Taking the upper half of the insertion into the sinkhole Ⅰ203 of the power block 200 as an example.

[0044] Make the oblique cutter surface II110 close to the inner oblique surface I206, and make the side surface I105 close to the left side surface 205.

[0045] The threaded rod 501 of the bolt 500 is screwed into the threaded hole 202, so that the end of the threaded rod 501 is embedded in the groove II 104. At this time, the punch II of the double-headed punch 100 is close to the recess I 203 of the power block 200, and the tip of the cutter II 102 is suspended in the recess II 204.

[0046] The right guide roller 300 presses against the side II 106 of the double-headed punch 100, and the left guide roller 400 presses against the side I 105 of the double-headed punch 100. The power block 200 drives the double-headed punch 100 to move up and down smoothly and linearly.

[0047] After the working cutter head I101 wears out, the double-headed punch 100 can be removed from the power block 200, and the cutter head I101 and cutter head II102 can be interchanged.

[0048] As described above, a double-headed punch 100 is provided, which is generally configured with a parallelogram-shaped longitudinal section and a rectangular (or square) cross-section. The inclined sides at both ends in the longitudinal direction are respectively configured as inclined blade surfaces I 109 and II 110. On the surfaces of the two transverse sides, grooves I 103 and II 104 for fitting and fixing are respectively provided adjacent to the corresponding inclined blade surfaces I 109 and II 110. Preferably, the term "adjacent" here means that they are adjacent to each other in the longitudinal direction but do not overlap. This spacing helps to ensure the rigidity of the corresponding inclined blade surfaces I 109 and II 110. The term "quadrilateral" here refers to the overall outer contour shape, ignoring the influence of local unevenness such as grooves I 103 and II 104.

[0049] As described above, a power block is provided for cooperating with the aforementioned double-headed punch 100 to form a punch assembly. This power block has a fitting groove opening to one side. The bottom surface of the fitting groove includes an inner inclined surface I206 near the opening side and an inner inclined surface II207 away from the opening side. The inner inclined surfaces I206 and II207 are not coplanar; that is, in a longitudinal cross-sectional view, they are a broken line composed of two line segments forming a predetermined angle with each other. This allows the double-headed punch 100 to be inserted into the fitting groove along its left side 205 (the groove wall adjacent to the inner inclined surface I206), so that the inclined blade surface I109 or the inclined blade surface II110 can fit against the inner inclined surface I206, and simultaneously the corresponding blade... The pointed end extends beyond the inner inclined surface I 206 and into the bottom of the groove, where the inner inclined surface II 207 forms the bottom surface. It does not contact the inner inclined surface II 207 but forms a gap with it. Simultaneously, in the longitudinal section view, the width of the fitting groove is greater than the width of the double-headed punch 100. That is, the tip will not contact the opposite side of the inner inclined surface I 206 (i.e., the groove wall opposite the inner inclined surface I 206, corresponding to the right side 208). The power block also has a threaded hole 202 communicating with the fitting groove. Bolts 500 are inserted into grooves I 103 or II 104 to fix the double-headed punch 100 in the fitting groove. The punch assembly also includes a right guide roller 300 and a left guide roller 400 disposed on both sides of the double-headed punch, for respectively abutting against the two opposite sides of the double-headed punch.

[0050] Advantages: Both ends are punches (punch I and punch II). When one punch wears out, the other end can be replaced and the machine can continue to be used, doubling the service life and saving costs. The special structure of the power block 200 can be perfectly adapted to the double-ended punch 100, which has punches at both ends.

[0051] The double-headed punch 100 shown above has a rectangular cross-section, but it is not limited to this and can also be formed into other polygonal or prismatic shapes as needed.
